[0001] The invention relates to the technical field of electric power pole tower operation, in particular to a portable safety belt suspension trolley for electric power pole tower operation. Background Art

[0002] Power pole tower operations refer to the work activities related to the installation, maintenance, inspection and transformation of power facilities carried out by power system workers on pole towers and their surrounding areas. Such operations usually involve high-altitude operations.

[0003] Currently, when working on a power pole tower, construction workers need to wear a safety belt before climbing the pole tower. The two hooks of the safety belt are connected to the top of the pole tower, higher than the position of the workers. Then, one of the hooks on the side is unhooked from the pole tower, moved upward for a distance, and reconnected to a more secure point. After ensuring that the hook on one side is firmly connected, the other hook is unhooked, moved upward and connected to the new position. In this continuous climbing process, the workers need to repeat the operation and consume physical strength. Frequent operation of the safety belt hooks will take up a lot of time, reduce the climbing speed, and lead to low work efficiency.

[0004] Therefore, we proposed a portable safety belt suspension trolley for power work tower operations in order to solve the problems raised above. Summary of the Invention

[0011] Preferably, the outer surfaces of the four first rotating plates are in contact with the outer surfaces of the four second rotating plates respectively, the four second rotating plates form a group of two, and the outer surfaces of each group of the second rotating plates are fixedly connected with a second fixed shaft near the two side edges.

[0012] Preferably, the four first rotating plates form a group of two each, and a third fixed shaft is fixedly connected between the outer surfaces of each group of the first rotating plates near the two side edges, and a groove is provided on the outer surface of one side of the two fixed plates.

[0013] Preferably, ropes are movably sleeved between the outer surfaces of two of the second fixed shafts and two of the third fixed shafts, the outer surfaces of the two ropes movably penetrate the inner wall of the groove, and the outer surfaces of the two ropes are coupled with safety hooks.

[0014] Preferably, a pressure plate is movably provided between the outer surfaces of the other two second fixed shafts and the other two third fixed shafts, and a sliding groove is provided on the inner walls of the two pressure plates near the two side edges, and the inner walls of the four sliding grooves are respectively slidably connected to the outer surfaces of the other two second fixed shafts and the other two third fixed shafts.

[0015] Preferably, the outer surfaces of the two movable blocks are fixedly connected to the second connecting plates, the outer surfaces of the two second connecting plates are provided with strong magnets, the inner walls of the two fixed blocks are movably embedded with second rotating shafts, the outer surfaces of the two second rotating shafts are fixedly connected to baffles, and the outer surfaces of the two baffles are respectively fixedly connected to the outer surfaces of the two second connecting plates.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0017] 2. When the portable safety belt hanging trolley for electric power pole tower operation drives the construction workers to move upward, the construction workers' own gravity will tighten the rope, and the rope will drive the second fixed axis and the third fixed axis to move, thereby driving the pressure plate to move. When the pressure plate contacts the baffle, it will exert pressure on the baffle, and the baffle will exert force on the moving block, so that the two moving blocks will drive the first anti-slip pad and the second anti-slip pad to fit more closely with the outer surface of the pole tower, ensuring a tight connection between the portable safety belt hanging trolley for electric power pole tower operation and the pole tower when moving.

[0018] 3. When the outer surfaces of the first anti-slip pad and the second anti-slip pad are in close contact with the outer surface of the pole tower, the first anti-slip pad and the second anti-slip pad will increase the friction with the pole tower, ensuring that the electric power pole tower operation can carry the safety belt hanging trolley and travel normally outside the pole tower.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figure 1-8 The present invention provides a technical solution: a portable safety belt hanging trolley for power tower operation, comprising two fixed blocks 1, a moving assembly 2 is arranged inside the two fixed blocks 1, and the two moving assemblies 2 include a moving block 201, the outer surfaces of the two moving blocks 201 are movably covered with a first anti-slip pad 202, the inner walls of the two moving blocks 201 are fixedly embedded with a first rotating shaft 208 near the edges of both sides, the outer surfaces of the four first rotating shafts 208 are movably covered with a rotating wheel 205, and the four rotating wheels 205 are each a group of two, and a shoe is arranged between the outer surfaces of each group of rotating wheels 205. Belt 203, the outer surfaces of the two tracks 203 are fixedly covered with a second anti-slip pad 204, the outer surfaces of the two moving blocks 201 slide with the inner walls of the two fixed blocks 1 respectively, the outer surfaces of the two moving blocks 201 are fixedly connected with the first connecting plate 206, the outer surfaces of the two first connecting plates 206 are provided with motors 207, wherein the two first rotating shafts 208 are respectively provided at the output ends of the two motors 207, the inner walls of the two moving blocks 201 are movably embedded with fixed rods 209, and the outer surfaces of the two fixed rods 209 are respectively fixedly embedded in the inner walls of the two fixed blocks 1.

[0023] In this embodiment, when the electric power pole tower operation can be carried out with a safety belt hanging trolley, the construction personnel first connect the trolley to the pole tower, and the construction personnel first move the two moving components 2. The construction personnel rotate the moving block 201, and the moving blocks 201 move back to back. The inner wall of the moving block 201 rotates along the outer surface of the fixed rod 209, and the moving block 201 drives the moving component 2, the second connecting plate 4 and the strong magnet 5 to move back to back until the outer surfaces of the two moving blocks 201 can accommodate the pole tower. The construction personnel place the two moving blocks 201 on the outer surface of the pole tower and rotate the two moving blocks 201 again. At this time, the two moving blocks 201 will move toward each other until the outer surfaces of the two first anti-slip pads 202 are squeezed against the outer surface of the pole tower. The outer surfaces of the two second anti-skid pads 204 are pressed and contacted with the outer surface of the pole tower. At the same time, when the two moving blocks 201 move toward each other to embrace the outer surface of the pole tower, the two second connecting plates 4 will be driven to move toward each other, and the two second connecting plates 4 will drive the two strong magnets 5 to move toward each other. In the process of moving toward each other, the two strong magnets 5 will generate a mutual attraction. The mutual attraction generated by the two strong magnets 5 will drive the two second connecting plates 4 to move closer to each other, and the two second connecting plates 4 will drive the two moving blocks 201 to move closer to each other. The two moving blocks 201 will drive the outer surfaces of the two first anti-skid pads 202 to stick to the outer surface of the pole tower. At the same time, the two second anti-skid pads 204 will stick to the outer surface of the pole tower. The construction workers The worker hangs the external safety belt inside the two safety hooks 308, and then starts the two motors 207. The motor 207 will drive one of the first rotating shafts 208 to rotate. The first rotating shaft 208 will drive the outer surface of the wheel 205 to rotate. The wheel 205 will drive the track 203 to rotate. When the track 203 rotates, it will also drive the second anti-skid pad 204 and the other rotating wheel 205 to rotate. The other rotating wheel 205 will drive the first rotating shaft 208 to rotate. The outer surface of the first rotating shaft 208 will rotate on the inner wall of the moving block 201. The second anti-skid pad 204 will move along the outer surface of the tower when rotating and moving, and will drive the moving component 2 and the safety hook 308 to move. The moving component 2 will move along the outer surface of the tower, and the safety hook 308 will move. 8 will drive the construction workers' safety belts to move, and the safety belts will drive the construction workers to move along the outer surface of the tower. At the same time, the shape of the tower is thin at the top and thick at the bottom. When the moving component 2 drives the construction workers to move upward along the outer surface of the tower, the diameter of the tower is slowly getting smaller. At the same time, the attraction force between the two strong magnets 5 will drive the two strong magnets 5 to approach each other in the process of the tower diameter slowly getting smaller. The two strong magnets 5 will drive the two second connecting plates 4 to move, and the two second connecting plates 4 will drive the two moving blocks 201 to approach the tower, so that the outer surfaces of the first anti-slip pad 202 and the second anti-slip pad 204 are closely fitted with the outer surface of the tower, thereby being able to adapt to the diameter change of the tower. By setting the moving component 2,When construction workers climb a pole tower, they first place the two moving blocks 201 on the outer surface of the pole tower. The mutual attraction between the two strong magnets 5 causes the outer surfaces of the first anti-slip pad 202 and the second anti-slip pad 204 to fit tightly against the outer surface of the pole tower. Then, the hook on the safety belt is connected to the safety hook 308, and the motor 207 is started to rotate the crawler 203, which can drive the moving assembly 2 to move along the outer surface of the pole tower, thereby driving the construction workers to move along the outer surface of the pole tower. Construction workers do not need to repeatedly climb manually, which reduces climbing time and solves the problem of workers having to frequently operate the safety belt hooks, which takes up a lot of time and reduces work efficiency.

[0024] like Figure 1-8 As shown, the outer surfaces of the two fixed blocks 1 are provided with a clamping assembly 3, and the two clamping assemblies 3 include a fixed plate 301. The outer surfaces of the two fixed plates 301 are fixedly connected to the outer surfaces of the two fixed blocks 1 respectively. The inner walls of the two fixed plates 301 are fixedly embedded with a first fixed shaft 302. The outer surfaces of the two first fixed shafts 302 are movably sleeved with a first rotating plate 303 near both ends. The outer surfaces of the two first fixed shafts 302 are movably sleeved with a second rotating plate 304 near both ends. The outer surfaces of the four first rotating plates 303 are respectively in contact with the outer surfaces of the four second rotating plates 304. The four second rotating plates 304 are grouped in pairs. The outer surfaces of each group of second rotating plates 304 are fixedly connected with a second fixed shaft 305 near the edges on both sides. The four first rotating plates 303 are grouped in pairs. A third fixed shaft 306 is fixedly connected between the outer surfaces of each group of first rotating plates 303 near the edges on both sides, and a groove 310 is provided on the outer surface of one side of the two fixed plates 301. A rope 307 is movably sleeved between the outer surfaces of the two second fixed shafts 305 and the two third fixed shafts 306. The outer surfaces of the two ropes 307 are movably passed through the inner walls of the grooves 310. The outer surfaces of the two ropes 307 are coupled with safety hooks 308. A pressure plate 309 is movably sleeved between the outer surfaces of the other two second fixed shafts 305 and the other two third fixed shafts 306. The inner walls of the two pressure plates 309 are provided with sliding grooves 311 near the edges on both sides. The inner walls of the four sliding grooves 311 are slidably connected to the outer surfaces of the other two second fixed shafts 305 and the other two third fixed shafts 306 respectively.

[0025] In this embodiment, when the electric power tower operation can be carried out with a portable safety belt hanging trolley, the construction worker will hang the safety belt with the two safety hooks 308, and then start the motor 207 to drive the moving component 2 to move. When the moving component 2 moves, it will drive the clamping component 3 to move. When the clamping component 3 moves upward, it will drive the two safety hooks 308 to move. When the two safety hooks 308 move upward along the tower, the construction worker's own gravity will drive the two safety hooks 308 to fall downward, and the safety hooks 308 will drive the rope 307 to be tightened. When the rope 307 is tightened, it will drive the second fixed shaft 305 and the third fixed shaft 306 When the first and second fixed shafts 305 and 306 are moved closer to each other, the second fixed shaft 305 and the third fixed shaft 306 will drive the first rotating plate 303 and the second rotating plate 304 to rotate. The inner walls of the first rotating plate 303 and the second rotating plate 304 will rotate along the outer surface of the first fixed shaft 302. At the same time, the first rotating plate 303 and the second rotating plate 304 will drive the outer surfaces of the corresponding second fixed shaft 305 and the third fixed shaft 306 to slide along the inner wall of the sliding groove 311 in the pressing plate 309, which will drive the pressing plate 309 to move. The outer surface of the pressing plate 309 will contact the baffle 7 during the movement, squeezing the baffle 7. When the construction workers themselves The heavier the weight, the greater the tension of the rope 307. Therefore, when the pressure plate 309 is driven to move, the greater the force of the pressure plate 309 on the baffle 7, the greater the extrusion force exerted by the pressure plate 309 on the baffle 7, and the extrusion force exerted on the baffle 7 will drive the outer surface of the second rotating shaft 6 to rotate along the inner wall of the fixed block 1. At the same time, the force of the baffle 7 will act on the second connecting plate 4. The two second connecting plates 4 will drive the two strong magnets 5 and the two moving blocks 201 to approach each other, thereby strengthening the clamping of the two moving blocks 201 and the two first anti-slip pads 202 on the pole tower. By setting the clamping component 3, the device can be carried when the power pole tower operation is carried out. When the safety belt hanging trolley drives the construction workers to move upward, the construction workers' own gravity will tighten the rope 307, and the rope 307 will drive the second fixed shaft 305 and the third fixed shaft 306 to move, thereby driving the pressure plate 309 to move. When the pressure plate 309 contacts the baffle 7, it will apply pressure to the baffle 7, and the baffle 7 will apply force to the moving block 201, so that the two moving blocks 201 will drive the first anti-slip pad 202 and the second anti-slip pad 204 to fit more closely with the outer surface of the pole tower, ensuring the tight connection between the portable safety belt hanging trolley for power pole tower operation and the pole tower when moving.

[0026] like Figure 1-8As shown, the outer surfaces of the two movable blocks 201 are fixedly connected to the second connecting plates 4, the outer surfaces of the two second connecting plates 4 are provided with strong magnets 5, the inner walls of the two fixed blocks 1 are movably embedded with second rotating shafts 6, the outer surfaces of the two second rotating shafts 6 are fixedly connected to baffles 7, and the outer surfaces of the two baffles 7 are fixedly connected to the outer surfaces of the two second connecting plates 4 respectively.

[0027] In this embodiment, when the trolley with a portable safety belt hanging on the electric power pole tower is operating, when the trolley climbs up along the pole tower, the outer surfaces of the two first anti-slip pads 202 and the second anti-slip pads 204 will contact the outer surface of the pole tower. The materials used for the first anti-slip pads 202 and the second anti-slip pads 204 have a certain elasticity, which can reduce the vibration generated when the trolley moves along the pole tower, and at the same time can increase the friction between the trolley and the pole tower, ensuring that the trolley with a portable safety belt hanging on the electric power pole tower operation can travel normally outside the pole tower.

[0028] The method of use and working principle of this device: When the electric power pole tower operation can carry a safety belt hanging trolley for operation, the construction workers first place the two moving blocks 201 on the outer surface of the external pole tower, rotate the two moving blocks 201 to drive the outer surfaces of the two first anti-skid pads 202 to squeeze and contact the outer surface of the external pole tower, and the two strong magnets 5 at this time will generate a force of attraction. The attraction generated by the two strong magnets 5 will drive the outer surfaces of the first anti-skid pads 202 and the second anti-skid pads 204 on the two moving blocks 201 to stick to the outer surface of the external pole tower, and then the construction workers will hang the external safety belt on the inside of the two safety hooks 308, and then start the two motors 207. The motor 207 will drive the crawler 203 to rotate, and the crawler 203 will drive the second anti-skid pad 204 to move along the outer surface of the external pole tower, thereby driving the construction workers to move. Most existing external The shape of the pole tower is thin at the top and thick at the bottom. The attraction force between the two strong magnets 5 will drive the two strong magnets 5 to approach each other as the diameter of the external pole tower gradually decreases, thereby driving the two moving blocks 201 to approach the external pole tower. At the same time, the gravity of the construction workers themselves will drive the two safety hooks 308 to fall downward, and the safety hooks 308 will drive the ropes 307 to be tightened. When the ropes 307 are tightened, they will drive the first rotating plate 303 and the second rotating plate 304 to rotate. The first rotating plate 303 and the second rotating plate 304 will drive the pressure plate 309 to move, and the pressure plate 309 will squeeze the baffle 7. The squeezing force on the baffle 7 will act on the second connecting plate 4. The two second connecting plates 4 will drive the two strong magnets 5 and the two moving blocks 201 to approach each other, so as to strengthen the clamping of the two first anti-slip pads 202 on the external pole tower driven by the two moving blocks 201.

[0029] The wiring diagram of the motor in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to actual use, so the control method and wiring arrangement of the motor are no longer explained in detail.
