[0019] Please see Figures 1-8This utility model provides a lightweight lightning protection lifting device, including a first side plate 100 and a second side plate 102. A plurality of connecting columns 104 are fixed between the first side plate 100 and the second side plate 102 on one side close to each other. A rotating shaft 200 is movably connected between the first side plate 100 and the second side plate 102. One side of the rotating shaft 200 passes through the second side plate 102. A roll film 201 is wound onto the outer wall of the rotating shaft 200. A lower plate 300 is fixed to one side of the second side plate 102. A ratchet 301 is fixed to one side of the outer wall of the rotating shaft 200. A middle plate 500 is fixed to one side of the lower plate 300. A first pawl 302 is movably connected to one side of the middle plate 500 and the lower plate 300. A second pawl 305 is movably connected to the other side of the middle plate 500 and the lower plate 300. The first pawl 302 and the second pawl 305 are respectively engaged with the ratchet 301. A swing assembly is provided on one side of the lower plate 300.
[0020] Further as Figure 5 As shown, screws 303 are connected to both sides of one side of the lower plate 300. A first tension spring 304 is fixed on the outer wall of one screw 303. One end of the first tension spring 304 is fixed to one side of the first pawl 302. A second tension spring 306 is fixed on the outer wall of the other screw 303. One end of the second tension spring 306 is fixed to one side of the second pawl 305.
[0021] By setting the first tension spring 304 and the second tension spring 306, the first pawl 302 or the second gripper is pushed by the swing block 400, and the first tension spring 304 or the second tension spring 306 can be stretched. Then, when the swing block 400 rotates in the opposite direction, the first tension spring 304 or the second tension spring 306 can be reset, thereby driving the first pawl 302 or the second pawl 305 to reset.
[0022] Further as Figure 5 As shown, the swing assembly includes a swing block 400, the middle of one side of the swing block 400 is movably connected to one side of the lower plate 300, and an adjusting rod 401 is fixed to the side of the swing block 400 away from the lower plate 300.
[0023] The swing assembly allows the first pawl 302 and the second pawl 305 to rotate, thereby facilitating the control of the ratchet 301 to rotate in the forward or reverse direction, so that the wound film 201 can be stretched or wound back.
[0024] The following is the working process of this solution: When assembling and using the lifting device, first place the lifting device in the corresponding position, then pull out the gap plate 800, and then push down the adjusting rod 401. The adjustment rod 401 moves and drives the swing block 400 to rotate, so that the swing block 400 pushes the second pawl 305 to rotate. At this time, the second tension spring 306 is stretched, and the second pawl 305 separates from the ratchet 301 until the ball 402 is engaged in the first contact hole 404 and the second contact hole 405, so that the position of the swing block 400 is fixed. Then, one foot steps on the foot pedal 803, so that the side of the foot pedal 803 near the roll film 201 contacts the roll film 201. This configuration increases the resistance when the film roll 201 is pulled out, preventing it from being pulled out too much. Then, pulling the pull bar 202 causes the rotating shaft 200 to rotate in the forward direction, allowing the film roll 201 to be pulled out a suitable length from below the rolling shaft 601. Next, releasing the foot pedal 803 causes the spring 805 to pull the foot pedal 803 away from the film roll 201. Then, pushing the adjusting rod 401 causes the swing block 400 to rotate. At this point, the ball 402 moves out of the first contact hole 404 and the second contact hole 405, the second pawl 305 is de-positioned, and the second tension spring 306 pulls the ratchet 301 to reset. When the adjusting rod 401 is reset, the ratchet 301 is positioned in two directions by the first pawl 302 and the second pawl 305, and the rotating shaft 200 will not rotate. Then, multiple reinforcing clamps 700 and pull rope clamps 708 are fixed to the outer wall of the vertical roll film 201. The reinforcing clamps 700 are used to strengthen the strength of the roll film 201, and the pull rope clamps 708 are used to connect the pull ropes 703. Then, the fixing sleeve 701 is put on the top of the roll film 201, and the top surface of the fixing sleeve 701 is fixed with the Tianji lightning rod 702. Then, one end of the down conductor 706 is fixed to the Tianji lightning rod 702, and then multiple pull ropes 703 are connected to the multiple pull rope clamps 708 respectively. On the 08, a single pull rope clamp 708 is connected to four pull ropes 703. The lifting device is then erected, and four ground stakes 709 are inserted into the holes on the two brackets 105 respectively. The ground stakes 709 are then inserted into the ground to fix the lifting device in place. Next, four circumferentially distributed anchors 704 are inserted into the ground. One end of each pull rope 703 is then fixed to the corresponding anchor 704. A striking cap 707 is placed on top of the corresponding portable grounding electrode 705, and the striking cap 707 is struck with a hammer to insert the portable grounding electrode 705 into the ground. Finally, the remaining portable grounding electrodes 705 are inserted into the ground to complete the setup of the entire device. Figure 8 As shown.
[0025] When disassembling the device, remove the anchor 704, portable grounding electrode 705, and ground nail 709 respectively, and remove the pull rope 703, reinforcing clamp 700, fixing sleeve 701, and pull rope clamp 708. Then push the adjusting rod 401 up so that the first pawl 302 is pushed and the first pawl 302 is separated from the ratchet 301. At this time, the rotating shaft 200 can rotate in the opposite direction. Then the mold can be wound up on the rotating shaft 200. Finally, the gap plate 800 is re-clamped between the first stop 801 and the roll film 201 so that the part of the roll film 201 near the pull bar 202 is fixed.
[0026] When the Tianji lightning rod 702 receives a lightning strike, the lightning current is safely discharged to the ground through the down conductor 706 and the portable grounding electrode 705.
[0027] As can be seen from the above working process: the ratchet 301, the first pawl 302, and the second pawl 305 allow the ratchet 301 to be in three modes: fixed, rotating forward, and rotating backward. This makes it easy to firmly fix the roll film 201 to the rotating shaft 200 when not in use. When using the lifting device, the rotating shaft 200 can only rotate forward. When retracting the roll film 201, the rotating shaft 200 can only rotate in the reverse direction. Through the roll film 201 and the reinforcing clamp 700, the lifting device can achieve lifting and lowering, which is simple to operate, has a low failure rate, and is more in line with the needs of field operations.
[0028] The grounding nails 709 allow the lifting device to be fixed to the ground. The pull rope clamps 708, pull ropes 703, and pull anchors 704 allow the roll-up membrane 201 to be held in a vertical position. The lightning rods 702, down conductors 706, and portable grounding electrodes 705 ensure that the lightning current is safely discharged to the ground, guaranteeing the safety of the equipment and personnel.
[0029] By using fiberglass and resin as the main material for the lifting device, injuries to personnel during transportation, use, and storage are avoided.
[0030] Further as Figure 7 As shown, the swing block 400 has two fixing plates 406 fixed on one side away from the lower plate 300. A side hole 407 is provided on one side of the fixing plate 406. A spring 408 is fixed on one side of the inner wall of the side hole 407. A ball 402 is fixed at the top of the spring 408. The ball 402 is engaged in the side hole 407.
[0031] By using the ball 402 and spring 408, when the pendulum block 400 rotates, the two balls 402 can respectively engage in the corresponding first contact hole 404 and second contact hole 405, thereby fixing the position of the pendulum block 400.
[0032] Further as Figure 4 As shown, the middle plate 500 has a first arc-shaped opening 501, a second arc-shaped opening 502, and a third arc-shaped opening 503 on one side away from the lower plate 300. The ball 402 on one side corresponds to the first arc-shaped opening 501, and the ball 402 on the other side corresponds to the second arc-shaped opening 502. The adjusting rod 401 passes through the third arc-shaped opening 503. An upper plate 403 is fixed to the middle plate 500 on one side away from the lower plate 300. The upper plate 403 has two first contact holes 404 and two second contact holes 405 on one side near the middle plate 500.
[0033] The first arc-shaped opening 501 and the second arc-shaped opening 502 allow the two balls 402 to pass through the middle plate 500, and the third arc-shaped opening 503 allows the adjusting rod 401 to pass through the middle plate 500.
[0034] Further as Figure 1 As shown, the first side plate 100 and the second side plate 102 are respectively fixed with side rods 600 close to each other on the top of one side, and the two side rods 600 are movably connected to each other on one side by a rolling shaft 601.
[0035] By using the roller 601, the position of the roll film 201 can be dynamically limited when it is pulled out from the rotating shaft 200, so that the pulled-out roll film 201 can be in a vertical position.
[0036] Further as Figure 1 As shown, a pull strip 202 is fixed to one end of the roll film 201, and two brackets 105 are fixed between the bottom of the first side plate 100 and the second side plate 102, which are far apart from each other.
[0037] The pull bar 202 allows one end of the roll film 201 to be easily pulled out.
[0038] Further as Figure 2 As shown, a first cover plate 101 is fixed to one side of the first side plate 100, a second cover plate 103 is fixed to one side of the second side plate 102, and a fourth arc-shaped opening 504 is provided on one side of the second cover plate 103, through which the adjusting rod 401 passes.
[0039] The fourth arc-shaped opening 504 allows the adjusting rod 401 to pass through the second cover plate 103.
[0040] Further as Figure 1 As shown, the material of the roll film 201 is glass fiber reinforced resin.
[0041] By using fiberglass and resin as the main material for the lifting device, injuries to personnel during transportation, use, and storage are avoided.
[0042] Further as Figure 1 As shown, a first stop bar 801 and a second stop bar 804 are fixed between the first side plate 100 and the second side plate 102. A rotating rod 802 is movably connected between the first side plate 100 and the second side plate 102. A foot pedal 803 is fixed to the outer wall of the rotating rod 802. A connecting foot 806 is fixed to the middle of the top surface of one side of the bracket 105. A tension spring 805 is fixed between the connecting foot 806 and the foot pedal 803. A gap plate 800 is provided between the first stop bar 801 and the roll film 201.
[0043] The gap plate 800 ensures that the portion of the film roll 201 near the pull bar 202 is fixed after it is wound up. The foot pedal 803 increases the resistance when the film roll 201 is pulled out, preventing it from being pulled out too much.
[0044] In summary: When assembling and using the lifting device, first place the lifting device in the appropriate position, then pull out the gap plate 800, and then push down the adjusting rod 401. The adjustment rod 401 moves and drives the swing block 400 to rotate, causing the swing block 400 to push the second pawl 305 to rotate. At this time, the second tension spring 306 is stretched, and the second pawl 305 separates from the ratchet 301 until the ball 402 engages with the first contact hole 404 and the second contact hole 405, thus fixing the position of the swing block 400. Then, step on the foot pedal 803 so that the side of the foot pedal 803 closest to the film 201 contacts the film 201. This setup allows for... This increases the resistance when the film roll 201 is pulled out, preventing it from being pulled out too much. Then, the pull bar 202 is pulled, causing the rotating shaft 200 to rotate forward, allowing the film roll 201 to be pulled out a suitable length from below the rolling shaft 601. Next, the foot pedal 803 is released, pulling the spring 805 to separate the foot pedal 803 from the film roll 201. Then, the adjusting rod 401 is pushed up, causing the swing block 400 to rotate. At this point, the ball 402 moves out of the first contact hole 404 and the second contact hole 405, the second pawl 305 is depositioned, and the second tension spring 306 pulls the ratchet 301 to reset. At this point, the adjusting rod 4... 01. After reset, ratchet 301 is positioned in two directions by the first pawl 302 and the second pawl 305, preventing the rotating shaft 200 from rotating. Then, multiple reinforcing clamps 700 and pull rope clamps 708 are fixed to the outer wall of the vertical roll film 201. The reinforcing clamps 700 are used to strengthen the roll film 201, and the pull rope clamps 708 are used to connect the pull ropes 703. Next, a fixing sleeve 701 is fitted onto the top of the roll film 201, with a lightning rod 702 fixed to its top surface. Then, one end of the down conductor 706 is fixed to the lightning rod 702, and multiple pull ropes 703 are connected to the multiple pull rope clamps 708. A single pull rope clamp 708 is connected to four pull ropes 703. The lifting device is then erected, and four ground stakes 709 are inserted into the holes on the two brackets 105. The ground stakes 709 are then inserted into the ground to secure the lifting device. Next, four circumferentially distributed anchors 704 are inserted into the ground. One end of each pull rope 703 is then fixed to the corresponding anchor 704. A striking cap 707 is placed on top of the corresponding portable grounding electrode 705, and the striking cap 707 is struck with a hammer to insert the portable grounding electrode 705 into the ground. Finally, the remaining portable grounding electrodes 705 are inserted into the ground to complete the setup of the entire device. Figure 8 As shown.
[0045] When disassembling the device, remove the anchor 704, portable grounding electrode 705, and ground nail 709 respectively, and remove the pull rope 703, reinforcing clamp 700, fixing sleeve 701, and pull rope clamp 708. Then push the adjusting rod 401 up so that the first pawl 302 is pushed and the first pawl 302 is separated from the ratchet 301. At this time, the rotating shaft 200 can rotate in the opposite direction. Then the mold can be wound up on the rotating shaft 200. Finally, the gap plate 800 is re-clamped between the first stop 801 and the roll film 201 so that the part of the roll film 201 near the pull bar 202 is fixed.
[0046] When the Tianji lightning rod 702 receives a lightning strike, the lightning current is safely discharged to the ground through the down conductor 706 and the portable grounding electrode 705.
[0047] Among them, the four portable grounding electrodes 705 are connected to the down conductors 706 respectively.
