Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and particularly to a cable laying trolley for a nuclear power cable tray. Background Art

[0002] Electronic components are mainly divided into three categories: circuit components, connection components, and devices. Cables belong to connection components and are used to achieve the physical connection of various components in a circuit. Cables play a core role in transmitting electrical energy and signals in a circuit and are an indispensable part of an electronic system. Their classifications include single-core cables, multi-core cables, shielded cables, etc., and are widely used in fields such as electronic devices and communication systems.

[0003] A tunnel cable automatic laying trolley with the publication number CN210350628U includes a bottom plate, a protective cover, and a laying bracket. The bottom plate is provided with a motor and a protective plate. The motor is bolted to the bottom plate, and the protective plate is bolted to the side of the bottom plate; the laying bracket is provided with a bracket, a bottom rod, a top rod, a diameter controller, and a control rod. The bracket is welded to both ends of the bottom plate, the bottom rod is embedded between the brackets, the top rod is embedded above the bottom rod, the diameter controller is connected to both ends of the top rod by interference fit, and the control rod is connected between the bracket and the diameter controller. The beneficial effect of the present utility model is that by rotating and pushing the adjusting rod, the clamping plate and the clamping groove cooperate with each other to fix the adjusting rod on the bracket. At the same time, by driving the diameter controller to move in the opposite direction, the moving range of the cable is limited, so that the cable will not shift left and right during the laying process, resulting in laying deviation. The above patent limits the moving range of the cable by driving the diameter controller to move in the opposite direction, but the rotating plate needs to be rotated manually. Due to the working environment in a tunnel with poor light, incorrect operations are likely to occur. Summary of the Invention

[0028] Embodiment: Refer to Figure 1 - Figure 8 shown in a cable laying trolley for a nuclear power bridge, including a bottom plate 1. Wheels 101 are fixedly connected to the four corners of the bottom surface of the bottom plate 1. A handle 102 is fixedly connected to one side of the top surface of the bottom plate 1. A bracket 103 is fixedly installed on the bottom plate 1. Storage grooves 104 are provided on both sides of the bracket 103. A wire roller 105 is rotatably connected inside the storage grooves 104; it further includes a limiting component, a positioning component, and a driving component. The limiting component is arranged on the frame 2 for transmitting the cable. The positioning component is arranged on the frame 2 for cooperating with the limiting component for use. The driving component is arranged on the bottom plate 1 for adjusting the positioning component.

[0029] Specifically, it should be noted here that both the oil cylinder 217 and the servo motor 407 are electrically connected to the existing control unit through wires, and the specific working principle between them is cited through the existing technology, so no more details will be elaborated here.

[0030] As an implementation manner in this embodiment, the limiting component includes a frame 2 fixedly installed on the bottom plate 1. The middle positions on both sides of the frame 2 are rotatably connected with a main shaft 201. One end of the main shaft 201 is fixedly connected with a linkage plate 202. One end of the main shaft 201 is rotatably connected with a first arm plate 203. The other end of the first arm plate 203 is rotatably connected to a first side plate 204.

The second side plate 211 is fixedly connected to one side of a second fixing plate 212. A second sliding sleeve 213 is fixedly installed on the second fixing plate 212. The second sliding sleeve 213 is slidably connected to the limiting rod 207. The middle position of the top surface of the second fixing plate 212 is fixedly connected with an oil cylinder 217. The top end of the oil cylinder 217 is fixedly installed on the frame 2. A pair of insertion rods 214 are movably inserted into the second fixing plate 212. The top ends of the pair of insertion rods 214 are fixedly connected with a collar 215. A spring 216 is sleeved on the pair of insertion rods 214. Both ends of the spring 216 are fixedly connected to one side of the second fixing plate 212 and one side of the collar 215 respectively. The bottom ends of the pair of insertion rods 214 are fixedly connected to a third fixing plate 218. A second hinge seat 219 is fixedly installed on the bottom surface of the third fixing plate 218. A second limiting roller 220 is rotatably connected to the second hinge seat 219.

[0031] Specifically, when it is necessary to adjust the distance between the first limiting roller 209 and the second limiting roller 220, the oil cylinder 217 pushes the second fixing plate 212 to move downward. The movement of the second fixing plate 212 causes the linkage plate 202 to rotate through the second arm plate 210 on the second side plate 211. The rotation of the linkage plate 202 causes the first arm plate 203 at the other end of the linkage plate 202 to push the first fixing plate 205 on the first side plate 204 to move. Place the cable between the first limiting roller 209 and the second limiting roller 220, and through the continuous movement of the second fixing plate 212 and the first fixing plate 205, make the second limiting roller 220 and the first limiting roller 209 fit on the surface of the cable.

[0032] As an implementation manner in this embodiment, the positioning component includes a bracket 3 fixedly connected to the frame 2. A positioning plate 301 is fixedly connected to the bracket 3. Slide bars 302 are fixedly connected to both ends of the positioning plate 301. A roller 303 is slidably connected to the slide bars 302. The roller 303 is rotatably connected to a docking plate 304. A third limiting roller 305 is rotatably connected to the docking plate 304. A frame body 306 is fixedly connected to one side of the docking plate 304. A push rod 307 is fixedly connected to the middle position of the frame body 306. The push rod 307 is movably inserted into the positioning plate 301. A sleeve 308 is fixedly connected to one end of the push rod 307. A guide wheel 309 is rotatably connected to the surface of the sleeve 308. A first shaft seat 310 is fixedly connected to the outside of the positioning plate 301. A rod body 311 is rotatably connected to the first shaft seat 310. A pair of driven plates 312 are fixedly connected to the top end of the rod body 311. A chute 313 is formed in the driven plate 312. The guide wheel 309 is slidably connected to the inside of the chute 313.

[0033] Specifically, the driven plate 312 on the rod body 311 is rotated by the driving component. The rotation of the driven plate 312 enables the guide wheel 309 to slide inside the chute 313, thereby facilitating the pushing of the push rod 307. The other end of the push rod 307 is fixedly connected to the frame body 306. The movement of the frame body 306 is caused by the pushing of the push rod 307. The frame body 306 is fixedly connected to the docking plate 304, and the docking plate 304 is rotatably connected with the roller 303. The roller 303 is slidably connected to the slide bar 302. The movement of the frame body 306 enables the roller 303 on the docking plate 304 to slide on the slide bar 302, increasing the stability of the movement of the docking plate 304. The movement of the docking plate 304 enables the third limiting roller 305 to limit both sides of the cable.

[0034] As an implementation manner in this embodiment, the driving component includes a gear 4 fixedly connected to the rod body 311. A toothed plate 401 is meshed with the gear 4. One end of the toothed plate 401 is fixedly connected to an adjusting plate 402. A pair of positioning rods 403 are movably inserted into the adjusting plate 402. A pull ring 404 is fixedly connected to one end of the pair of positioning rods 403. The other end of the positioning rod 403 is fixedly connected to a second shaft seat 405. One end of the second shaft seat 405 is fixedly connected to a mounting frame 406. The mounting frame 406 is fixedly installed on the bottom plate 1. A servo motor 407 is fixedly installed on the top surface of the mounting frame 406. A threaded rod 408 is fixedly connected to the output end of the servo motor 407. A sleeve plate 409 is threadedly connected to the threaded rod 408. The sleeve plate 409 is fixedly installed at the middle position of the adjusting plate 402.

[0035] Specifically, when the rod body 311 needs to be rotated, the servo motor 407 on the mounting bracket 406 operates. A threaded rod 408 is fixedly connected to the output end of the servo motor 407. The operation of the servo motor 407 causes the threaded rod 408 to rotate. A sleeve plate 409 is threadedly connected to the threaded rod 408. The rotation of the threaded rod 408 causes the sleeve plate 409 to drive the adjusting plate 402 to move. Tooth plates 401 are fixedly connected to both ends of the adjusting plate 402, and the tooth plates 401 are meshed with the gear 4. The movement of the adjusting plate 402 drives the gear 4 to rotate through the tooth plates 401, thereby facilitating the rotation of the rod body 311 on the gear 4.

[0036] Working principle of the present invention: When the distance between the first limiting roller 209 and the second limiting roller 220 needs to be adjusted, the oil cylinder 217 pushes the second fixing plate 212 to move downward. The movement of the second fixing plate 212 causes the linkage plate 202 to rotate through the second arm plate 210 on the second side plate 211. The rotation of the linkage plate 202 causes the first arm plate 203 at the other end of the linkage plate 202 to push the first fixing plate 205 on the first side plate 204 to move. Place the cable between the first limiting roller 209 and the second limiting roller 220. The continuous movement of the second fixing plate 212 and the first fixing plate 205 causes the second limiting roller 220 and the first limiting roller 209 to fit on the surface of the cable.

[0037] The driving component causes the driven plate 312 on the rod body 311 to rotate. The rotation of the driven plate 312 causes the guide wheel 309 to slide inside the chute 313, thereby facilitating the pushing of the push rod 307. The other end of the push rod 307 is fixedly connected to the frame body 306. The movement of the frame body 306 is caused by the pushing of the push rod 307. The frame body 306 is fixedly connected to the docking plate 304, and a roller 303 is rotatably connected to the docking plate 304. The roller 303 is slidably connected to the sliding rod 302. The movement of the frame body 306 causes the roller 303 on the docking plate 304 to slide on the sliding rod 302, increasing the stability of the movement of the docking plate 304. The movement of the docking plate 304 causes the third limiting roller 305 to limit both sides of the cable.

[0038] When the rod body 311 needs to be rotated, the servo motor 407 on the mounting bracket 406 operates. A threaded rod 408 is fixedly connected to the output end of the servo motor 407. The operation of the servo motor 407 causes the threaded rod 408 to rotate. A sleeve plate 409 is threadedly connected to the threaded rod 408. The rotation of the threaded rod 408 causes the sleeve plate 409 to drive the adjusting plate 402 to move. Tooth plates 401 are fixedly connected to both ends of the adjusting plate 402, and the tooth plates 401 are meshed with the gear 4. The movement of the adjusting plate 402 drives the gear 4 to rotate through the tooth plates 401, thereby facilitating the rotation of the rod body 311 on the gear 4.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
