Description

Technical Field

[0001] The invention belongs to the technical field of power transmission and transformation line construction, and particularly relates to a power transmission and transformation line construction device with a protective function. Background Art

[0002] Based on existing technology, when maintenance personnel perform maintenance and construction on high-tower power transmission and transformation lines, they need to use protective devices to ensure that they are firmly connected to the tower or the cables in the transmission and transformation lines to prevent high-altitude falls. However, the existing protective devices have relatively limited functions and lack facilities for maintenance personnel to rest. As a result, maintenance personnel are easily exhausted physically and mentally during high-intensity work. When cracks or damage occur in the cables of the power transmission and transformation lines, maintenance personnel need to manually connect new cables to the damaged cables.

[0012] More preferably, the extrusion block is made of rubber.

[0013] More preferably, the guide wheel is made of rubber.

[0014] The advantages and positive effects of the present invention are: (1) The maintenance personnel carry the support plate on their backs and then climb up the tower. Then, they pull out the four slide bars from the corresponding round tubes, and make the clamps on each slide bar be mounted on the cables in the power transmission and transformation line. Then, they connect the four clamps to the cables in the power transmission and transformation line, and then lock the slide bar on the round tube, so that the support plate is firmly connected to the cables in the power transmission and transformation line. Then, they connect the high-altitude work safety belt worn by the maintenance personnel to the two pull rings through the buckle, and at the same time, they connect the high-altitude work safety belt to the cables in the power transmission and transformation line, so as to ensure that the maintenance personnel are firmly connected to the tower or the cables in the power transmission and transformation line, so as to prevent high-altitude falling accidents.

[0015] (2) By placing one leg of the maintenance worker on the front of the support board and the other leg on the back of the support board, the maintenance worker's overall center of gravity is more balanced, allowing the maintenance worker to take a short rest on the support board and replenish food and water to restore physical strength. The seat cushion is made of rubber, which can improve the comfort of the maintenance worker.

[0016] (3) When the maintenance personnel moves, the support plate moves accordingly. When the maintenance personnel detects an abnormal condition in a part of the cable, the maintenance personnel can step on the upper surface of the support plate to make the maintenance personnel's body center of gravity more stable. In addition, since the surface of the seat cushion is provided with an anti-slip layer, the friction between the support plate and the sole of the maintenance personnel's shoe can be increased, thereby reducing the possibility of the maintenance personnel slipping when stepping on the support plate.

[0017] (4) The maintenance personnel sits astride the support plate, takes out the cable, and places one end of the cable against the cutter. The maintenance personnel then pulls the handle by hand, and the movement of the handle drives the arc rod to move, and the movement of the arc rod drives the cutter to move and compresses the elastic member I, so that the cutter moves along the outer surface of the cable in a circle, thereby cutting the insulation layer of the cable. The cable is then pulled to move, so that the insulation layer at the end of the cable falls off, and then the insulation layer at the other end of the cable is stripped off, and the cable is then connected across the damaged cable, thereby maintaining the cable. The maintenance personnel can also keep their body center more balanced when working at height, and can more conveniently handle new cables, thereby improving the safety of maintenance work and reducing the intensity of maintenance work.

[0018] (5) By manually rotating the threaded rod, the rotation of the threaded rod drives the extrusion block to move toward the guide wheel, so that the extrusion block and the guide wheel can press against the cable together and compress the elastic part II, thereby clamping and limiting the cable, thereby further reducing the intensity of the maintenance personnel's work, improving the convenience of maintenance work, and making the length of the cable insulation stripping more accurate.

[0029] In the prior art, when maintenance personnel perform maintenance work on high-tower power transmission and transformation lines, they need to use protective devices to ensure that they are firmly connected to the tower or the cables 3 in the power transmission and transformation lines to prevent accidents caused by falling from heights. However, the existing protective devices have relatively limited functions and lack facilities for maintenance personnel to rest. This results in maintenance personnel easily feeling physically and mentally exhausted during high-intensity work. In order to solve the above problem, when maintaining the cable 3, the maintenance tools and several new cables 2 are placed in the storage box 14 in advance, and then the maintenance personnel carry the support plate 1 with the two elastic straps 12, and then climb the tower, thereby driving all the connected components to move to the tower, and the initial positions of the bracket 203 and all the components connected to the bracket 203 are all located below the support plate 1, and then when the maintenance personnel carry the support plate 1, the bracket 203 and all the components connected to the bracket 203 will not affect the maintenance personnel, and then Pull the four slide bars 202 out of the corresponding round tubes 201 in sequence, so that the clamps 2021 on each slide bar 202 are mounted on the corresponding cables 3 in the power transmission and transformation line, and then connect the four clamps 2021 to the cables 3 in the power transmission and transformation line in sequence, and then lock the slide bar 202 on the round tube 201 through the locking piece between the round tube 201 and the slide bar 202, so that the support plate 1 is firmly connected to the cables 3 in the power transmission and transformation line, and then connect the high-altitude work safety belt worn by the maintenance personnel to the two pull rings 13 through the buckle, as shown in FIG. Figure 1 As shown, at the same time, the maintenance personnel independently connect the high-altitude work safety belt they are wearing to the cable 3 in the power transmission and transformation line, thereby ensuring that they are firmly connected to the high tower or the cable 3 in the power transmission and transformation line to prevent high-altitude falling accidents.

[0030] When maintenance personnel feel tired after long periods of high-intensity work, they can sit on the support board 1 with both legs, that is, with the front of the support board 1 as the reference, one leg of the maintenance personnel is on the front of the support board 1, and the other leg is on the back of the support board 1, so that the overall center of gravity of the maintenance personnel is more balanced, so that the maintenance personnel can take a short rest on the support board 1, and at the same time replenish food and water to restore physical strength. The seat cushion 11 is made of rubber, which can improve the comfort of the maintenance personnel.

[0031] When the maintenance personnel are carrying out maintenance inspections along the line, they step on the cable 3 connected to the clamp 2021 with their feet, and at the same time hold the other two cables 3 above the support plate 1 with their hands, and move along the cable 3 to inspect various parts of the cable 3. The maintenance personnel move by pulling the two pull rings 13 through the high-altitude work safety belt and lock buckle worn on their body, thereby driving the support plate 1 to move, and then driving all the connected parts to move. When it is detected that there is an abnormal state in a part of the cable 3, the maintenance personnel stops moving, and the maintenance personnel's Both feet can be stepped on the upper surface of the support plate 1 so that the center of gravity of the maintenance personnel's body can be more stable. Compared with the existing maintenance personnel, when repairing the cable 3, the maintenance personnel need to step on the cable 3 and then inspect the cable 3, which easily makes the center of gravity of the maintenance personnel unstable. This method can greatly increase the stability of the maintenance personnel when repairing the cable 3, and because the surface of the seat cushion 11 is provided with an anti-slip layer, the friction between the support plate 1 and the sole of the maintenance personnel's shoe can be increased, thereby reducing the possibility of slipping when the maintenance personnel steps on the support plate 1.

[0032] When the cable 3 in the power transmission and transformation line is cracked or damaged, the maintenance personnel need to manually connect a new cable 2 to the damaged cable 3. During this process, the cable 2 needs to be held firmly by the hand and the maintenance tools need to be used to handle the new cable 2, which makes the maintenance work very cumbersome and easily causes the center of gravity of the body to shift during the operation, especially for the power transmission and transformation line far away from the tower, which will seriously affect the safety of the maintenance work. To solve the above problem, when the maintenance personnel connect the cable 2 to the cable 3 in the power transmission and transformation line, the maintenance personnel sit on the support plate 1 in the same way as above, take out the cable 2 stored in the storage box 14, and then pull the bracket 203 so that the bracket 203 is rotated 180 degrees counterclockwise along the circular tube 201 with the right side of the support plate 1 as the reference. The rotation of the bracket 203 drives all the connected parts to rotate, so that the arc plate 208 is located above the support plate 1. Figure 3As shown, the maintenance personnel then holds the cable 2 and places one end of the cable 2 into the inner side of the arc plate 208 and against the cutter 212, and then the maintenance personnel pulls the handle 210 by hand, the handle 210 moves to drive the arc rod 209 to move, the arc rod 209 moves to drive the cutter 212 to move, and compresses the elastic member I 211, so that the cutter 212 moves along the outer surface of the cable 2 for a circle, thereby cutting the insulation layer of the cable 2 and dividing the insulation layer of the cable 2 into two sections. At this time, the cutter 212 is against the space between the two insulation layers, and then the maintenance personnel The maintenance personnel pulls the cable 2 to move, thereby causing the insulation layer at the end of the cable 2 to fall off, and then puts the other end of the cable 2 into the inner side of the arc plate 208 and presses against the cutter 212, and then strips off the insulation layer at the other end of the cable 2, thereby stripping off the insulation layer at both ends of the cable 2, and then cross-connects the cable 2 to the damaged cable 3, thereby maintaining the cable 3, and enabling the maintenance personnel to have a more balanced center of body when working at high altitudes, and to handle the new cable 2 more conveniently, thereby improving the safety of the maintenance work and reducing the intensity of the maintenance work.

[0033] It should be noted that in order to adapt to cables 2 of different specifications, the pump 214 is controlled to start operating to inflate or suck air into the catheter 215, thereby causing the airbag 213 to deform. The deformation of the airbag 213 drives the cutter 212 to deform, thereby allowing the cutter 212 to adapt to cables 2 of different specifications, thereby stripping the insulation layer of cables 2 of different specifications. Example 2

[0034] On the basis of Example 1, according to Figure 4 and Figure 8 As shown, it also includes a clamping and limiting system; the clamping and limiting system is connected to the bracket 203; the clamping and limiting system includes a support frame 301, a threaded rod 302, an extrusion block 303, a sliding rod 304, a guide wheel 305 and an elastic member II 306; the support frame 301 is fixed to the lower surface of the bracket 203; the threaded rod 302 is rotatably connected to the support frame 301; the end of the threaded rod 302 is rotatably connected to the extrusion block 303; the sliding rod 304 is slidably connected to the support frame 301; the lower part of the sliding rod 304 is rotatably connected to the guide wheel 305; an elastic member II 306 is fixed between the sliding rod 304 and the support frame 301, and the elastic member II 306 is a spring, one end of the elastic member II 306 is fixed to the sliding rod 304, and one end of the elastic member II 306 is fixed to the support frame 301.

[0035] The squeezing block 303 is made of rubber and is used to prevent damage to the cable 2 .

[0036] The guide wheel 305 is made of rubber and is used to increase the friction between the guide wheel 305 and the cable 2.

[0037] When the insulation layer of the new cable 2 is stripped, in order to further reduce the intensity of the maintenance personnel's work, improve the convenience of the maintenance work, and make the length of the insulation layer of the cable 2 stripped more accurately, the maintenance personnel place the new cable 2 between the extrusion block 303 and the guide wheel 305, and manually rotate the threaded rod 302. The rotation of the threaded rod 302 drives the extrusion block 303 to move toward the guide wheel 305. The movement of the extrusion block 303 drives the cable 2 to move until the cable 2 is against the guide wheel 305. The movement of the guide wheel 305 drives the sliding rod 304 to move, thereby stretching the elastic member II 306, thereby making the extrusion block 30 3 and the guide wheel 305 jointly press against the cable 2, thereby clamping and limiting the cable 2, and then the end of the cable 2 is pressed against the cutter 212, and the support 205 is moved, so that the support 205 moves along the fixed rod 204. Since the fixed rod 204 is provided with a scale line, the moving distance of the support 205 can be known, so that the length of the insulation layer stripped at both ends of the cable 2 is consistent, so that the maintenance personnel no longer need to hold the cable 2 during the process of stripping the insulation layer of the cable 2, thereby further reducing the intensity of the maintenance personnel's work, improving the convenience of the maintenance work, and making the length of the insulation layer stripped of the cable 2 more accurate.
