Movable lifting lightning rod

1. The scope of use of the movable lifting lightning rod

Movable lifting lightning rod is also called mobile lightning rod and movable lifting rod lightning rod. The movable lifting lightning rod is actually a lightning rod, which can attract the surrounding lightning and discharge it in advance, and transmit the lightning current to the ground through its own grounding conductor. Avoid the object of protection being directly struck by lightning. Erection and support of various wireless communication antennas, lights, cameras, night vision devices, common lightning rods and other equipment. It is especially suitable for the assembly and use of various instruments with strong mobility and frequent movement. Such as satellite signal receiving antenna, erection and installation of mobile radar lightning rod, etc.

2. Applicable environment of movable lifting lightning rod

Working temperature: electric type -45°C~+55°C, manual type ±55°C. The maximum wind resistance is 30m/s (the installation foundation is firm and the cable is in the state), and it is used for the assembly of various instruments that are flat, hard and frequently move. Such as satellite signal receiving antenna, erection and installation of mobile radar lightning rod, etc. Solid ground (indoor and outdoor), interior and exterior decoration of vehicles and square warehouses, installation on ships and offshore drilling platforms.

3. Technical parameters of movable lifting lightning rod

 4. Conditions for selection of movable lifting lightning rod

1. Determine the maximum lift, closing height, bearing weight, and windward area of the load

2. Determine whether to install on the ground, outside the vehicle or inside the vehicle

3. The electric type determines whether to choose vertical or horizontal

4. The electric type determines the power used by the motor

5. Structural characteristics and working principle of movable lifting lightning rod

The structure is compact, and it is composed of a lifting rod, a tripod bracket, a hand crank, and a cable system. The power is transmitted by the combination of hand shaft, bevel gear, lead screw, screw nut and wire rope to achieve the purpose of lifting. The "double extension mechanism" is adopted, that is, the movable rods of each section rise and fall at the same time, the speed is fast, and the steel wire rope can be seen exposed after rising. It can be self-locked at any height without sliding down.

6. Requirements for erection of movable lifting lightning rod

1. The lifting lightning rod must be installed on a flat and hard foundation to ensure that it does not sink or tilt after bearing the load.

2. The loading of the lifting lightning rod is not allowed to exceed the specified weight, and the loading should act on the axis of the rod body. It is forbidden to tilt and bend the lifting lightning rod due to asymmetrical loads off the axis.

3. The lifting lightning rod must be vertical to the horizontal plane, and the allowed inclination is not more than 0.5°.

4. When the wind speed exceeds 14m/S, there must be a pull wire for erection or lifting.

5. The closing lock hook must be removed before raising the lifting pole.

6. The fasteners that fix the load must be tightened before lifting.

7. Smashing is strictly prohibited during use, installation or transportation to prevent deformation of the rod body.

8. If abnormal phenomena such as inflexible lifting or jamming occur during the lifting process, the work should be stopped immediately, and the cause should be found out and the fault should be eliminated before operation.

9. Remember that the short cable of the three-layer cable box of the fixed pipe must be in the locked state during the lifting and lowering process, see Figure 1 for the detailed view of the locked state.

7. Ground erection, lifting and pulling of movable lifting lightning rod

1. Choose a flat, hard and open site, and the square radius can meet the requirements of the ground nails for guy wires, that is, the site is a circular area greater than or equal to R=12.6m.

2. Referring to Figure 2, install the upper hinge, outriggers and diagonal braces on the lifting rod and then install the latch.

3. Adjust each cable lock pin of the cable box to the unlocked state (that is, pull out the lock pin handle and rotate it 90° to make the lock pin handle boss out of the lock body groove.

4. Hang the long, middle and short cable hooks of the cable box on the cable holes on the upper, middle and lower layers of the lifting rod respectively.

5. Put the load on the lifting rod and tighten the set screw and take off the closure lock hook.

6. Stand up the lifting rod and hold it, then unfold the outriggers, pull out the telescopic rod lock and pull out the telescopic rod to put it in place and lock it.

7. Put the foot support plate under the feet and turn the adjusting bolt to fine-tune the feet so that all three legs are supported and the lifting rod is in a vertical state.

8. Align the position of the cable hole on the top of the lifting pole, take the lifting pole as the center, and nail three ground nails to the ground with a radius of 12.6m, and the ground nail hanging ring faces the lifting pole.

9. Hang the cable box hooks of the three cable boxes on the three ground nail rings respectively.

10. Adjust the short pull wire lock pin of the pull wire box to make it in the locked state (that is, pull out the lock pin handle and rotate 90° so that the lock pin handle boss enters the groove of the lock body) Insert the pull wire box handle into the pull wire box short pull wire handle Inside the hole, turn the handle of the cable box clockwise, tighten the cable at three points at the same time, and fix the lifting rod in a vertical position.

11. Unscrew the cover of the hand crank shaft, insert the hand crank handle onto the hand crank shaft, and evenly shake the hand crank clockwise to raise the lift bar. During the lifting process, place the pull wire while raising, and designate a special person to observe the vertical condition of the lifting rod, and command the pull wire box operator to loosen or tighten the pull wire as needed to keep the lifting rod vertically raised. When you see the lower part of the second section When the red mark line is exposed or it feels unsteady, the lifting pole has been raised to the maximum height.

12. Adjust the length of the cable box and the lock pins of the middle cable to make them in the locked state, insert the handles of the cable box into the jacks of the long and middle cable handles of the cable box respectively, rotate the handle of the cable box clockwise and hear a "click" "Click" sound, tighten the pull wire at three points at the same time, and fix the lifting rod in the vertical position.

8. Lowering and dismantling of movable lifting lightning rod

1. Shake the hand crank counterclockwise and slowly drop the lifting rod. The cable box operator follows the cable and follows the

The observer instructs to adjust the stay wire to keep the lifting rod vertically lowered until the lifting rod lands in place.

2. Hold the lifting rod, remove the cable box from the ground nail, and retract the outrigger telescopic rod inward.

3. Remove the outriggers and diagonal braces and lay down the lifting rod.

4. Unload the load, take off the pull wire hook, then hang the closure lock hook and tighten the closure lock, etc.

Nine, removable lightning rod maintenance and maintenance

1. After the lifting rod is used in the rain, it should be dried before it is lowered to the closed state and then lowered to the closed state.

2. When the lifting pole is closed and parked in the open air, a protective cloth cover should be worn to prevent rain and dust from entering.

3. If it is not used for a long time, it should be raised and dried every half a month in the rainy season; it should be raised and dried every one month in the non-rainy season.

4. After the long-term erection of the lifting pole in the field, check the erection of the lifting pole after a strong wind or at intervals of one month. The pole body should not be tilted, deformed, and no slack is allowed. If any problem is found, it should be eliminated in time.
