Description

Technical Field

[0001] The invention relates to the technical field of power overhead line equipment, in particular to a power overhead line construction device and a construction method thereof. Background Art

[0002] Existing overhead lines are generally fixed to electric poles by means of tie bars. When using tie bars to fix overhead lines, it is necessary to first pull the overhead lines from the pay-off reel to the pole, and then the construction workers put the overhead lines on the tie bars on the pole to complete the line laying operation.

[0003] When installing overhead lines, a section of overhead line that is slightly longer than the two poles is taken, and then the overhead line is raised to the top of the pole through a device for installation. Due to the long distance between the two poles and the heavy weight of the overhead line, it is impractical to pull the overhead line manually. Manual pulling will cause the overhead line to have a larger curvature after installation. The larger the curvature, the greater the inertia when blown by the wind, which can easily cause wear and tear of the overhead line or even cause it to fall off, causing a safety accident. Summary of the invention

[0004] The purpose of the present invention is to provide an overhead power line construction device and a construction method thereof, so as to solve the problem that it is impractical to pull the overhead line manually due to the long distance between two electric poles and the large mass of the overhead line. Manual pulling will cause the overhead line to have a larger curvature after installation. The larger the curvature, the greater the inertia when it is blown by the wind, which can easily cause the overhead line to wear and even fall off, causing a safety accident.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a construction device for an overhead power line, comprising a ground, wherein two tensioning mechanisms are arranged on the top of the ground, wherein the tensioning mechanism comprises a moving box arranged on the top of the ground, wherein a rotating shaft is rotatably mounted on the moving box, wherein the front end of the rotating shaft extends out of the moving box, wherein a round block is fixedly sleeved on the rotating shaft, and further comprising: The circular block is provided with a plurality of rectangular grooves, and a tension spring is fixedly installed on the inner wall of a side where the plurality of rectangular grooves are close to each other, and an isosceles trapezoidal block is fixedly installed on the ends of the plurality of tension springs that are away from each other, and the plurality of isosceles trapezoidal blocks are slidably connected to the plurality of rectangular grooves, and the ends of the plurality of isosceles trapezoidal blocks that are away from each other extend out of the rectangular grooves, and a toothed plate is arranged above the moving box.

A plurality of card slots are formed on the outer wall of the utility pole. A fixing cap is slidably sleeved on the utility pole. The fixing cap is adapted to the plurality of card slots. A U-shaped limiting block is fixedly installed on the fixing cap. Two limiting wheels are rotatably installed on the U-shaped limiting block.

[0009] Further, driving mechanisms are respectively arranged on the two moving boxes. The driving mechanism includes a driving groove formed on the moving box. A driving motor is fixedly installed on the inner wall of the back surface of the driving groove. A driving rod is fixedly installed on the output shaft of the driving motor. The end of the driving rod is fixedly connected to the driving groove. A traction cable is wound around the driving rod. A fixing rod is fixedly installed on the moving box. The traction cable passes through the two limiting wheels. The end of the traction cable is fixedly connected to the fixing rod.

[0010] Further, sliding mechanisms are respectively arranged on the two moving boxes. The sliding mechanism includes a U-shaped plate fixedly installed on the left inner wall of the moving box. A special-shaped square rod is fixedly installed in the U-shaped plate. Two sliders are slidably sleeved on the special-shaped square rod. Activity rods are respectively hingedly installed on the two sliders. A U-shaped mounting plate is hingedly installed at one ends of the two activity rods close to each other. An arc-shaped wheel is rotatably installed on the U-shaped mounting plate. Two positioning springs are sleeved on the special-shaped square rod. One ends of the two positioning springs away from each other are both fixedly connected to the U-shaped plate. One ends of the two positioning springs close to each other are respectively fixedly connected to the two sliders.

[0011] Further, two clamping mechanisms are respectively arranged on the two special-shaped square rods.

The right end of the connecting rod is hingedly connected to the corresponding slider. A strip-shaped adapting rod is slidably installed on the left side of the U-shaped plate. A U-shaped adapting plate is fixedly installed on the left side of the U-shaped plate.

The right end of the strip-shaped adapting rod extends into the U-shaped plate. An adapting spring is sleeved on the strip-shaped adapting rod. The left end of the adapting spring is fixedly connected to the U-shaped adapting plate. The right end of the adapting spring is fixedly connected to the U-shaped plate. A T-shaped clamping plate is fixedly installed at the right end of the strip-shaped adapting rod; Two clamping grooves are formed in the outer wall of the electric pole. The two T-shaped clamping plates are respectively adapted to the two clamping grooves.

[0012] Further, the method steps of the electric power overhead line construction device are as follows: S1: First, move the two moving boxes to the designated positions of the two electric poles. Then, push the moving box. The moving box drives the U-shaped plate to move towards the electric pole, so that the two T-shaped clamping plates on the U-shaped plate are inserted into the clamping grooves on the electric pole. During the process of the U-shaped plate approaching the electric pole, the arc-shaped wheel will first contact the electric pole. The arc-shaped wheel will drive the U-shaped mounting plate to move away from the electric pole under the reaction force of the electric pole. The U-shaped mounting plate will drive the two movable rods to move away from each other. The movable rods drive the two sliders to move away from each other. At this time, the two clamping springs on the special-shaped square rod will be moved away from each other by the sliders and generate compressive deformation. The sliders drive the two connecting rods to move away from each other. The connecting rods drive the two U-shaped guiding blocks to move towards the electric pole at the same time. The two U-shaped guiding blocks will be inserted into the holes on the two strip-shaped adapting rods to play a role in limiting and fixing the strip-shaped adapting rods, avoiding the instability and shaking of the T-shaped clamping plates in the clamping grooves during the rising process of the moving box, and avoiding the risk of the staff on the device falling. The contact of the arc-shaped wheel with the electric pole will reduce the friction during the rising process when the moving box rises, improve the smoothness of the rising of the moving box. At the same time, the reaction force will also be applied to the two movable rods under the elastic force of the two clamping springs. The reaction force and the contact of the arc-shaped wheel can support the moving box; S2: Then, place the overhead line on the two rotating wheels. Then, rotate the threaded fixing rod. The threaded fixing rod drives the pressing plate to descend. The pressing plate presses and fixes the overhead line placed on the rotating wheels. At this time, most of the overhead line is still on the ground. Then, start the driving motor. The driving motor drives the driving rod to rotate. The driving rod winds up the traction cable. At this time, the traction cable becomes shorter. The traction cable will pull the fixing rod to generate an upward force. The fixing rod will drive the whole moving box to rise. During the rising process of the moving box, the contact of the arc-shaped wheel can keep the moving box balanced; S3: During the rising process of the moving box, the round block will contact the tooth plate, and the teeth on the tooth plate will drive several isosceles trapezoidal blocks to rotate, and the isosceles trapezoidal blocks will drive the round block to rotate, and the round block will drive the rotating shaft to rotate, and the rotating shaft will drive the rotating wheel to rotate, and the rotating wheel will drive the fixed plate to rotate, and the fixed plate will drive the extrusion plate to rotate under the action of the threaded fixing rod, and the extrusion plate will drive the overhead line to rotate, and the overhead line will be tightened from both ends in the direction away from each other, and the curvature in the middle of the overhead line will decrease; S4: After the overhead line is pulled to a certain extent, the stress of the overhead line will force the shaft to stop rotating. At this time, the round block will no longer rotate during the rising process. When the tooth plate contacts the isosceles trapezoidal block, the tooth plate will exert a reaction force on the isosceles trapezoidal block to squeeze the isosceles trapezoidal block. The isosceles trapezoidal block will move into the rectangular groove. At this time, the tension spring will be compressed and deformed. When the isosceles trapezoidal block moves into the rectangular groove to a certain distance, the teeth on the tooth plate will slide over the corresponding isosceles trapezoidal block under the action of the inclined surface of the isosceles trapezoidal block. At this time, the stress of the overhead line will offset the compression elastic force of the tension spring. S5: During the rotation of the rotating wheel, the trapezoidal block will be driven by the inclined surface to leave the limiting slot, and the trapezoidal block will drive the bar to move away from the rotating wheel. At this time, the telescopic spring is compressed and deformed. During the rotation of the rotating wheel, the trapezoidal block will be continuously stuck in the limiting slot under the elastic force of the telescopic spring. When the overhead line reaches the specified height and no longer moves, the trapezoidal block stuck in the limiting slot will also stop moving. Since the trapezoidal block is a right-angled trapezoid, the inclined surface on the trapezoidal block will only leave the limiting slot when the overhead line is tightened. Under the action of the vertical surface of the trapezoidal block, it will support the limiting slot to ensure that the trapezoidal block will not reverse and keep the overhead line in a tightened state, which is convenient for the staff to install the overhead line under the appropriate tension of the overhead line at high altitude.

[0013] The present invention has the following beneficial effects: (1)A construction device for overhead power lines according to the present invention. First, move two mobile boxes to the designated positions of two utility poles. Then, push the mobile boxes. The mobile boxes drive the U-shaped plate to move towards the utility pole, causing the two T-shaped clamping plates on the U-shaped plate to snap into the clamping grooves on the utility pole. During the process of the U-shaped plate approaching the utility pole, the arc-shaped wheels will first come into contact with the utility pole. The arc-shaped wheels will drive the U-shaped mounting plate to move away from the utility pole under the reaction force of the utility pole. The U-shaped mounting plate will drive the two movable rods to move away from each other, and the movable rods will drive the two sliders to move away from each other. At this time, the sliders will cause the two clamping springs on the special-shaped square rod to move away from each other and produce compressive deformation. The sliders will drive the two connecting rods to move away from each other, and the connecting rods will drive the two U-shaped guiding blocks to move towards the utility pole at the same time. The two U-shaped guiding blocks will be inserted into the holes on the two strip-shaped adaptable rods to play a role in limiting and fixing the strip-shaped adaptable rods, avoiding the instability and shaking of the T-shaped clamping plates in the clamping grooves during the ascent of the mobile box, and avoiding the risk of the workers on the device falling. The contact of the arc-shaped wheels with the utility pole will reduce the friction during the ascent when the mobile box ascends, improving the smoothness of the ascent of the mobile box. At the same time, under the elastic force of the two clamping springs, a reaction force will also be exerted on the two movable rods. The reaction force, combined with the contact of the arc-shaped wheels, can support the mobile box, thereby reducing the wear of the T-shaped clamping plates in the clamping grooves; (2)A construction device for overhead power lines according to the present invention. Then, place the overhead line on the two rotating wheels. Then, rotate the threaded fixing rod. The threaded fixing rod drives the pressing plate to descend, and the pressing plate presses and fixes the overhead line placed on the rotating wheels. At this time, most of the overhead line is still on the ground. Then, start the driving motor. The driving motor drives the driving rod to rotate. The driving rod winds up the towing cable. At this time, the towing cable becomes shorter, and the towing cable will pull the fixing rod to generate an upward force. The fixing rod will drive the entire mobile box to rise. During the ascent of the mobile box, the contact of the arc-shaped wheels can maintain the balance of the mobile box and ensure the stability of the mobile box when the workers are working at high altitudes; (3)A construction device for overhead power lines according to the present invention. During the ascent of the mobile box, the round block will come into contact with the toothed plate. Under the action of the teeth on the toothed plate, a number of isosceles trapezoidal clamping blocks will be driven to rotate. The isosceles trapezoidal clamping blocks will drive the round block to rotate. The round block will drive the rotating shaft to rotate. The rotating shaft will drive the rotating wheel to rotate. The rotating wheel will drive the fixing plate to rotate. The fixing plate will drive the pressing plate to rotate under the action of the threaded fixing rod. The pressing plate will drive the overhead line to rotate. At this time, the overhead line will be tightened from both ends towards the direction of moving away from each other. At this time, the arc in the middle of the overhead line will decrease, ensuring that the overhead line will be tightened simultaneously during the ascent, saving manual pulling and improving the efficiency of pulling the overhead line; (4) The present invention provides an overhead power line construction device. After the overhead line is pulled to a certain extent, the stress of the overhead line will force the rotating shaft to stop rotating. At this time, during the process of the round block rising, since the round block no longer rotates, when the tooth plate contacts the isosceles trapezoidal block, the tooth plate will exert a reaction force on the isosceles trapezoidal block to squeeze the isosceles trapezoidal block. The isosceles trapezoidal block will move into the rectangular groove. At this time, the tensioning spring will be compressed and deformed. When the isosceles trapezoidal block moves into the rectangular groove to a certain distance, the teeth on the tooth plate will slide under the corresponding isosceles trapezoidal block under the action of the inclined surface of the isosceles trapezoidal block. At this time, the stress of the overhead line will offset the compressive elastic force of the tensioning spring, which not only ensures that the overhead line can continue to rise, but also ensures that the tooth plate is not affected by the isosceles trapezoidal block and does not rotate; (5) The present invention provides an overhead power line construction device. During the rotation of the rotating wheel, the trapezoidal block will be driven by the inclined surface to leave the limit slot, and the trapezoidal block will drive the bar to move away from the rotating wheel. At this time, the telescopic spring will be compressed and deformed. During the rotation of the rotating wheel, the trapezoidal block will be continuously stuck in the limit slot under the elastic force of the telescopic spring. When the overhead line reaches a specified height and no longer moves, the trapezoidal block stuck in the limit slot will also stop moving. Since the trapezoidal block is a right-angled trapezoid, the inclined surface on the trapezoidal block will only leave the limit slot when the overhead line is tightened. Under the action of the vertical surface of the trapezoidal block, the limit slot will be supported to ensure that the trapezoidal block will not be reversed, so that the overhead line remains in a tightened state, which is convenient for workers to install the overhead line at a high altitude with appropriate tension of the overhead line.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is a construction device for electric power overhead lines, including a ground 1. Two tensioning mechanisms 100 are arranged on the top of the ground 1. The tensioning mechanism 100 includes a moving box 101 arranged on the top of the ground 1. A rotating shaft 102 is rotatably installed on the moving box 101. The front end of the rotating shaft 102 extends outside the moving box 101. A round block 103 is fixedly sleeved on the rotating shaft 102. It further includes: A plurality of rectangular grooves 104 are provided on the round block 103, and tension springs 105 are fixedly installed on the inner walls of the plurality of rectangular grooves 104 on the sides close to each other, and isosceles trapezoidal clamping blocks 106 are fixedly installed on the ends of the plurality of tension springs 105 away from each other, and the plurality of isosceles trapezoidal clamping blocks 106 are slidingly connected to the plurality of rectangular grooves 104, and the ends of the plurality of isosceles trapezoidal clamping blocks 106 away from each other extend outside the rectangular grooves 104, and a toothed plate 107 is provided above the moving box 101.

[0020] like Figure 2 and Figure 5 As shown, a rotating mechanism 2 is respectively arranged on the two rotating shafts 102, and the rotating mechanism 2 includes a rotating wheel 201 fixedly sleeved on the rotating shaft 102, and a plurality of limit slots 202 are respectively opened on the front and back sides of the rotating wheel 201, and strip rods 203 are respectively slidably installed on the front and back sides of the moving box 101, and the ends of the two strip rods 203 close to each other are extended into the moving box 101, and the ends of the two strip rods 203 close to each other are respectively fixedly installed with trapezoidal blocks 204, and the two trapezoidal blocks 204 are respectively inserted into the corresponding two limit slots 202, and telescopic springs 205 are respectively sleeved on the two strip rods 203, and the ends of the two telescopic springs 205 away from each other are fixedly connected to the moving box 101, and the ends of the two strip rods 203 close to each other are respectively fixedly connected to the two trapezoidal blocks 204.

[0021] During the rotation of the rotating wheel 201, the trapezoidal block 204 will be driven by the inclined surface to leave the limiting slot 202, and the trapezoidal block 204 will drive the bar 203 to move away from the rotating wheel 201. At this time, the telescopic spring 205 is compressed and deformed. During the rotation of the rotating wheel 201, the trapezoidal block 204 will be continuously stuck in the limiting slot 202 under the elastic force of the telescopic spring 205. When the overhead line 304 reaches the specified height and no longer moves, the trapezoidal block 204 stuck in the limiting slot 202 will also stop moving.

[0022] like Figure 2 As shown, a fixing mechanism 3 is respectively provided on the two rotating wheels 201, and the fixing mechanism 3 includes a fixing plate 301 fixedly installed on the rotating wheel 201, a threaded fixing rod 302 is threadedly installed on the fixing plate 301, and the threaded fixing rod 302 penetrates the fixing plate 301, and an extrusion plate 303 is rotatably installed on the bottom end of the fixing plate 301, and the ends of the extrusion plates 303 away from each other extend to the rotating wheel 201 and are slidably connected to the rotating wheel 201.

[0023] The rotating wheel 201 drives the fixed plate 301 to rotate. The fixed plate 301 drives the pressing plate 303 to rotate under the action of the threaded fixing rod 302. The pressing plate 303 drives the overhead line 304 to rotate. At this time, the overhead line 304 is tightened from both ends in the direction away from each other. At this time, the arc in the middle of the overhead line 304 decreases, ensuring that the overhead line 304 is tightened simultaneously during the rising process, saving manual pulling and improving the efficiency of pulling the overhead line 304.

[0024] As Figure 6 shown, two limiting mechanisms 4 are provided on the top of the ground 1. The limiting mechanism 4 includes a utility pole 401 fixedly installed on the top of the ground 1. A plurality of card slots 402 are formed on the outer wall of the utility pole 401. A fixed cap 403 is slidably sleeved on the utility pole 401. The fixed cap 403 is adapted to a plurality of card slots 402. A U-shaped limiting block 404 is fixedly installed on the fixed cap 403. Two limiting wheels 405 are rotatably installed on the U-shaped limiting block 404.

[0025] By providing two limiting wheels 405, when the driving rod 503 rotates to tighten the towing cable 504, the towing cable 504 can play a role in limiting and guiding under the action of the two limiting wheels 405, improving the smoothness of the rotation of the towing cable 504.

[0026] As Figure 3 shown, driving mechanisms 5 are respectively provided on the two moving boxes 101. The driving mechanism 5 includes a driving groove 501 formed on the moving box 101. A driving motor 502 is fixedly installed on the inner wall of the back surface of the driving groove 501. A driving rod 503 is fixedly installed on the output shaft of the driving motor 502. The end of the driving rod 503 is fixedly connected to the driving groove 501. A towing cable 504 is wound around the driving rod 503. A fixed rod 505 is fixedly installed on the moving box 101. The towing cable 504 passes through the two limiting wheels 405. The end of the towing cable 504 is fixedly connected to the fixed rod 505.

[0027] The driving motor 502 drives the driving rod 503 to rotate. The driving rod 503 winds up the towing cable 504. At this time, the towing cable 504 becomes shorter. The towing cable 504 pulls the fixed rod 505 to generate an upward force. The fixed rod 505 drives the entire moving box 101 to rise.

[0028] As Figure 7As shown in the figure, sliding mechanisms 6 are respectively arranged on two moving boxes 101. The sliding mechanism 6 includes a U-shaped plate 601 fixedly installed on the left inner wall of the moving box 101. An irregular square rod 602 is fixedly installed inside the U-shaped plate 601. Two sliders 603 are slidably sleeved on the irregular square rod 602. Activity rods 604 are respectively hingedly installed on the two sliders 603. The ends of the two activity rods 604 close to each other are hingedly installed with a U-shaped mounting plate 605. An arc-shaped wheel 606 is rotatably installed on the U-shaped mounting plate 605. Two clamping springs 607 are sleeved on the irregular square rod 602. The ends of the two clamping springs 607 away from each other are fixedly connected to the U-shaped plate 601 respectively. The ends of the two clamping springs 607 close to each other are fixedly connected to the two sliders 603 respectively.

[0029] During the process of the U-shaped plate 601 approaching the electric pole 401, the arc-shaped wheel 606 will first come into contact with the electric pole 401. Under the reaction force of the electric pole 401, the arc-shaped wheel 606 will drive the U-shaped mounting plate 605 to move away from the electric pole 401. The U-shaped mounting plate 605 will drive the two activity rods 604 to move away from each other. The activity rods 604 drive the two sliders 603 to move away from each other. At this time, the sliders 603 will make the two clamping springs 607 on the irregular square rod 602 move away from each other and produce compressive deformation.

[0030] As Figure 1 and Figure 7 As shown in the figure, two clamping mechanisms 7 are respectively arranged on the two irregular square rods 602. The clamping mechanism 7 includes a U-shaped guiding block 701 slidably sleeved on the irregular square rod 602. A connecting rod 702 is hingedly installed on the U-shaped guiding block 701. The right end of the connecting rod 702 is hinged to the corresponding slider 603. A strip-shaped adapting rod 703 is slidably installed on the left side of the U-shaped plate 601. A U-shaped adapting plate 704 is fixedly installed on the left side of the U-shaped plate 601. The strip-shaped adapting rod 703 penetrates through the U-shaped adapting plate 704 and is slidably connected to the U-shaped adapting plate 704. The right end of the strip-shaped adapting rod 703 extends into the U-shaped plate 601. An adapting spring 705 is sleeved on the strip-shaped adapting rod 703. The left end of the adapting spring 705 is fixedly connected to the U-shaped adapting plate 704. The right end of the adapting spring 705 is fixedly connected to the U-shaped plate 601. A T-shaped clamping plate 706 is fixedly installed at the right end of the strip-shaped adapting rod 703; Two clamping grooves 707 are opened on the outer wall of the electric pole 401. The two T-shaped clamping plates 706 are respectively adapted to the two clamping grooves 707.

[0031] The slider 603 drives the two connecting rods 702 to move away from each other. The connecting rods 702 drive the two U-shaped guide blocks 701 to move simultaneously towards the direction close to the electric pole 401. The two U-shaped guide blocks 701 will insert into the holes on the two strip-shaped adaptive rods 703 to play a role in limiting and fixing the strip-shaped adaptive rods 703, preventing the T-shaped clamping plate 706 from being unstable and shaking in the clamping groove 707 during the rising process of the moving box 101, and avoiding the risk of the staff on the device falling.

[0032] As Figure 1-8 shown, a construction device for overhead power lines has the following method steps: S1: First, move the two moving boxes 101 to the designated positions of the two electric poles 401. Then, push the moving box 101. The moving box 101 drives the U-shaped plate 601 to move towards the direction close to the electric pole 401, so that the two T-shaped clamping plates 706 on the U-shaped plate 601 are clamped into the clamping grooves 707 on the electric pole 401. During the process of the U-shaped plate 601 approaching the electric pole 401, the arc-shaped wheel 606 will first come into contact with the electric pole 401. The arc-shaped wheel 606 will drive the U-shaped mounting plate 605 to move away from the electric pole 401 under the reaction force of the electric pole 401. The U-shaped mounting plate 605 will drive the two movable rods 604 to move away from each other. The movable rods 604 drive the two sliders 603 to move away from each other. At this time, the sliders 603 will cause the two clamping springs 607 on the special-shaped square rod 602 to move away from each other and produce compressive deformation. The sliders 603 drive the two connecting rods 702 to move away from each other. The connecting rods 702 drive the two U-shaped guide blocks 701 to move simultaneously towards the direction close to the electric pole 401. The two U-shaped guide blocks 701 will insert into the holes on the two strip-shaped adaptive rods 703 to play a role in limiting and fixing the strip-shaped adaptive rods 703, preventing the T-shaped clamping plate 706 from being unstable and shaking in the clamping groove 707 during the rising process of the moving box 101, and avoiding the risk of the staff on the device falling. When the arc-shaped wheel 606 comes into contact with the electric pole 401, it will reduce the friction during the rising process when the moving box 101 rises, improve the smoothness of the rising of the moving box 101. At the same time, under the elastic force of the two clamping springs 607, a reaction force will also be exerted on the two movable rods 604. The reaction force, combined with the contact of the arc-shaped wheel 606, can support the moving box 101; S2: Then place the overhead line 304 on the two rotating wheels 201, and then rotate the threaded fixing rod 302, the threaded fixing rod 302 drives the squeezing plate 303 to descend, and the squeezing plate 303 squeezes and fixes the overhead line 304 placed on the rotating wheel 201. At this time, most of the overhead line 304 is still on the ground, and then start the driving motor 502, the driving motor 502 drives the driving rod 503 to rotate, and the driving rod 503 reels the traction rope 504. At this time, the traction rope 504 becomes shorter, and the traction rope 504 will pull the fixing rod 505 to generate an upward force. The fixing rod 505 will drive the moving box 101 to rise as a whole. During the rising process of the moving box 101, the contact of the arc wheel 606 can keep the balance of the moving box 101; S3: During the rising process of the moving box 101, the round block 103 will contact the tooth plate 107, and the teeth on the tooth plate 107 will drive a number of isosceles trapezoidal blocks 106 to rotate, and the isosceles trapezoidal blocks 106 will drive the round block 103 to rotate, and the round block 103 will drive the rotating shaft 102 to rotate, and the rotating shaft 102 will drive the rotating wheel 201 to rotate, and the rotating wheel 201 will drive the fixed plate 301 to rotate, and the fixed plate 301 will drive the extrusion plate 303 to rotate under the action of the threaded fixing rod 302, and the extrusion plate 303 will drive the overhead line 304 to rotate, and at this time, the overhead line 304 will be tightened from both ends in the direction away from each other, and the curvature in the middle of the overhead line 304 will be reduced; S4: After the overhead line 304 is pulled to a certain extent, the stress of the overhead line 304 will force the rotating shaft 102 to stop rotating. At this time, during the rising process of the round block 103, since the round block 103 also stops rotating, when the tooth plate 107 contacts the isosceles trapezoidal block 106, the tooth plate 107 will give the isosceles trapezoidal block 106 a reaction force to squeeze the isosceles trapezoidal block 106, and the isosceles trapezoidal block 106 will move into the rectangular groove 104. At this time, the tensioning spring 105 is compressed and deformed. When the isosceles trapezoidal block 106 moves a certain distance into the rectangular groove 104, the teeth on the tooth plate 107 will slide over the corresponding isosceles trapezoidal block 106 under the action of the inclined surface of the isosceles trapezoidal block 106. At this time, the stress of the overhead line 304 will offset the compression elastic force of the tensioning spring 105. S5: During the rotation of the rotating wheel 201, the trapezoidal block 204 will be driven by the inclined surface to leave the limiting slot 202, and the trapezoidal block 204 will drive the bar 203 to move away from the rotating wheel 201. At this time, the telescopic spring 205 is compressed and deformed. During the rotation of the rotating wheel 201, the trapezoidal block 204 will be continuously stuck in the limiting slot 202 under the elastic force of the telescopic spring 205. When the overhead line 304 reaches the specified height and stops moving, The trapezoidal block 204 inserted into the limit slot 202 will also stop moving. Since the trapezoidal block 204 is a right-angled trapezoid, the inclined surface on the trapezoidal block 204 will only leave the limit slot 202 when the overhead line 304 is tightened. Under the action of the vertical surface of the trapezoidal block 204, the limit slot 202 will be supported to ensure that the trapezoidal block 204 will not reverse and the overhead line 304 will remain in a tightened state, which is convenient for the staff to install the overhead line 304 under the appropriate tension of the overhead line 304 at high altitude.

Then, push the mobile box (101), and the mobile box (101) drives the C-shaped plate (601) to move towards the utility pole (401), so that the two T-shaped clamping plates (706) on the C-shaped plate (601) are inserted into the clamping grooves (707) on the utility pole (401). During the process of the C-shaped plate (601) approaching the utility pole (401), the arc-shaped wheel (606) will first come into contact with the utility pole (401). The arc-shaped wheel (606) will drive the C-shaped mounting plate (605) to move away from the utility pole (401) under the reaction force of the utility pole (401). The C-shaped mounting plate (605) will drive the two movable rods (604) to move away from each other. The movable rods (604) will drive the two sliders (603) to move away from each other. At this time, the sliders (603) will cause the two clamping springs (607) on the special-shaped square rod (602) to move away from each other and produce compressive deformation. The sliders (603) drive the two connecting rods (702) to move away from each other.

When the arc-shaped wheel (606) contacts the utility pole (401), it will reduce the friction during the rising of the mobile box (101) when the mobile box (101) rises, improving the smoothness of the rising of the mobile box (101). At the same time, under the elastic force of the two clamping springs (607), a reaction force will also be exerted on the two movable rods (604). The reaction force, combined with the contact of the arc-shaped wheel (606), can support the mobile box (101); S2: Then, place the overhead line (304) on the two rotating wheels (201). Then, rotate the threaded fixing rod (302), and the threaded fixing rod (302) drives the pressing plate (303) to descend. The pressing plate (303) presses and fixes the overhead line (304) placed on the rotating wheel (201). At this time, most of the overhead line (304) is still on the ground. Then, start the driving motor (502), and the driving motor (502) drives the driving rod (503) to rotate. The driving rod (503) winds up the traction cable (504). At this time, the traction cable (504) becomes shorter, and the traction cable (504) will pull the fixing rod (505) to generate an upward force. The fixing rod (505) will drive the entire mobile box (101) to rise. During the rising process of the mobile box (101), the contact of the arc-shaped wheel (606) can keep the mobile box (101) balanced; S3: During the ascending process of the moving box (101), the round block (103) contacts the tooth plate (107), and the teeth on the tooth plate (107) drive a plurality of isosceles trapezoidal blocks (106) to rotate, and the isosceles trapezoidal blocks (106) drive the round block (103) to rotate, and the round block (103) drives the rotating shaft (102) to rotate, and the rotating shaft (102) drives the rotating wheel (201) to rotate, and the rotating wheel (201) drives the fixed plate (301) to rotate, and the fixed plate (301) drives the extrusion plate (303) to rotate under the action of the threaded fixing rod (302), and the extrusion plate (303) drives the overhead line (304) to rotate, and at this time, the overhead line (304) is tightened from both ends in a direction away from each other, and at this time, the arc in the middle of the overhead line (304) is reduced; S4: After the overhead wire (304) is pulled to a certain extent, the stress of the overhead wire (304) forces the rotating shaft (102) to stop rotating. At this time, during the process of the round block (103) rising, the round block (103) also stops rotating. When the tooth plate (107) contacts the isosceles trapezoidal block (106), the tooth plate (107) exerts a reaction force on the isosceles trapezoidal block (106) to squeeze the isosceles trapezoidal block (106). (106) will move into the rectangular groove (104), at which time the tension spring (105) will be compressed and deformed. When the isosceles trapezoidal block (106) moves a certain distance into the rectangular groove (104), the teeth on the tooth plate (107) will slide over the corresponding isosceles trapezoidal block (106) under the action of the inclined surface of the isosceles trapezoidal block (106). At this time, the stress of the overhead line (304) will offset the compression elastic force of the tension spring (105); S5: During the rotation of the rotating wheel (201), the trapezoidal block (204) will be driven by the inclined surface to leave the limiting slot (202), and the trapezoidal block (204) will drive the bar (203) to move in a direction away from the rotating wheel (201). At this time, the telescopic spring (205) is compressed and deformed. During the rotation of the rotating wheel (201), the trapezoidal block (204) will be continuously stuck in the limiting slot (202) under the elastic force of the telescopic spring (205). When the overhead line (304) reaches a specified height and stops moving, , the trapezoidal block (204) inserted into the limit slot (202) will also stop moving. Since the trapezoidal block (204) is a right-angled trapezoid, the inclined surface on the trapezoidal block (204) will only leave the limit slot (202) when the overhead line (304) is tightened. Under the action of the vertical surface of the trapezoidal block (204), the limit slot (202) will be supported to ensure that the trapezoidal block (204) will not reverse and the overhead line (304) will remain in a tightened state, which is convenient for workers to install the overhead line (304) at a suitable tension at high altitude.
