Description

Technical Field

[0001] This invention belongs to the field of electromechanical construction technology, and specifically relates to a cable laying device. Background Technology

[0002] In electromechanical construction, indoor cables are typically installed in cable trays on the ceiling. As a support structure for cables, cable trays neatly fix them in designated locations, preventing haphazard hanging or scattered cable arrangements and making cable laying and management more convenient. In electrical systems, cable maintenance and repair are unavoidable. Using cable trays makes the cable routing and location clear, allowing maintenance personnel to quickly locate and handle problems. Simultaneously, cable trays provide sufficient space for maintenance personnel to operate, improving work efficiency. This neat wiring method is not only aesthetically pleasing but also facilitates cable heat dissipation and ventilation, reducing safety hazards caused by cable overheating. Currently, cable trays generally use a U-shaped structure. When laying cables, manual movement of the cables into the grooves on the tray is required, which is inconvenient and poses certain safety hazards due to working at height. Summary of the Invention

[0003] The purpose of this invention is to provide a cable laying device that uses a scissor lift platform to assist manual cable laying.

[0004] The present invention is achieved through the following measures: a cable laying device, characterized in that it includes a scissor lift platform, a cable laying structure and a cable bridging structure set on the platform of the scissor lift platform; The cable bridge structure includes a base plate and upright plates symmetrically arranged on both sides of the base plate. A pivot is rotatably mounted on the upright plate near the cable tray. Sliding rods are symmetrically arranged at both ends of the upper part of the other upright plate. A connecting rod is fixedly mounted on the inner end of the two sliding rods. A spring is sleeved on the sliding rod. The outer end of the spring is fixed to the upright plate, and the inner end is fixed to the connecting rod. An upright is fixedly mounted above both ends of the connecting rod. A longitudinal rod parallel to the cable tray is fixedly mounted on the inner side of the upright. A mounting plate is fixedly mounted below the inner end of the longitudinal rod. A drive rod is rotatably mounted between the two mounting plates. A roller is rotatably mounted on the other end of the drive rod. A transverse rod facing the cable tray is fixedly mounted on the upper end of the upright. The outer ends of the two transverse rods are connected by a fixing rod. A mounting rod is mounted on the fixing rod. A ball is fixedly mounted on the inner end of the mounting rod. A cam is fixedly installed at one end of the rotating shaft near the bridge frame, which contacts the roller. The contact surface between the cam and the roller includes a small sector and a large sector concentric with the rotating shaft. The small sector and the large sector are connected by two symmetrically arranged arc-shaped parts. A limiting plate is concentrically provided on the outer end face of the cam. A sector-shaped boss is fixedly provided on the outer end face of the limiting plate. The outer end face of the sector-shaped boss and the outer end of the limiting plate are transitioned by an arc. The side of the sector-shaped boss is flush with the side of the large sector. The sector-shaped boss and the outer end face of the limiting plate can contact the sphere. A vertical rod is fixedly installed on the drive rod, and a support rod facing the cable tray is fixedly installed on the outer side of the vertical rod. A U-shaped frame is fixedly installed at the outer end of the support rod. A vertical roller is rotatably installed between the two side plates of the U-shaped frame. Ear plates are fixedly installed on the outer side of the two side plates, and a horizontal roller is rotatably installed on the ear plates. When the ball contacts the outer end face of the limiting plate, the roller contacts the small sector and the spring is not compressed; when the shaft rotates and the roller contacts the large sector, the ball begins to contact the outer end face of the sector boss, the spring is compressed after the drive rod is lifted, and the horizontal roller located below is lifted to a height higher than the side of the cable tray and moves from above the cable tray towards the cable tray.

[0005] It also includes a motor that drives the rotating shaft. The motor is fixed to the base plate, and the motor shaft and the rotating shaft are connected by a transmission mechanism. The transmission mechanism can be a belt drive or a chain drive.

[0006] The cable laying structure includes a base and columns fixedly installed on both sides of the base. A placement platform is fixedly installed on the upper end of the two columns. A drive shaft is rotatably installed on the two placement platforms. A cable reel is sleeved on the drive shaft. The cable is fixed to the drive shaft by screws.

[0007] 6. Two guide wheels with axes parallel to the drive shaft axis are rotatably mounted on the placement platform. The drive shaft is positioned between and tangential to the two guide wheels. Limiting plates are provided on the drive shaft and on the outer side of each guide wheel to prevent the drive shaft from detaching from the two guide wheels. A limiting block is fixed to the placement platform above the end of the drive shaft by screws. The limiting block prevents the drive shaft from detaching from the placement platform and is detachably connected for easy replacement of the cable reel.

[0008] A cable limiter is installed between the cable laying structure and the cable bridge structure. The cable limiter includes a support column and a ring fixed above the support column. Several bullseye bearings are evenly distributed circumferentially on the inner wall of the ring. The distance between two adjacent bullseye bearings is less than the outer diameter of the cable. The height of the ring is lower than the cable tray. This prevents the cable from being squeezed between two bullseye bearings. The support column is fixed to the platform of the scissor lift platform or to the base. The bullseye bearings are existing technology, and their specific structure will not be described in detail here. The spherical rolling elements of the bullseye bearings can contact the cable, facilitating cable positioning and reducing friction with the cable's outer wall.

[0009] The scissor lift platform, employing existing technology, generally includes a frame with drive wheels, a scissor bracket mounted on the frame, a telescopic rod that drives the scissor bracket to rise and fall, and a platform mounted on the scissor bracket. The telescopic rod is typically a hydraulic rod. Appropriate safety railings should be installed around the platform, depending on the actual situation, to ensure the safety of personnel using the platform.

[0010] How to use: The coiled cable is placed on the drive shaft and secured with screws. One end of the cable is passed through the ring and placed between the vertical roller and two horizontal rollers, then fixed to the cable tray with a clamp. The scissor lift platform moves along the cable tray to gradually lay the cable. The drive rod is initially in a horizontal position with the roller in contact with the small sector and the ball in contact with the outer end face of the limiting plate.

[0011] Once the device moves to the designated position, the motor is started. The motor drives the rotating shaft to rotate through the transmission mechanism. The rotation drives the cam and the limiting plate to rotate. When the roller contacts the large fan-shaped part on the cam, the ball contacts the fan-shaped boss. At this time, the drive plate is lifted and moves towards the cable tray. The cable is located above the cable tray on the vertical roller and the two horizontal rollers, which facilitates the laying of the cable. The beneficial effects of the technical solution provided by this invention are: it can assist in the manual laying of cables on cable trays. During the laying process, the scissor lift platform can move along the direction of the cable tray, gradually moving the cables to the cable tray. After the cables are fixed, subsequent laying can proceed. At this time, the cables are not concentrated on the cable tray but are located on the outside of the cable tray, which facilitates the construction work of the workers. During the laying process, the cables between the vertical rollers and the two horizontal rollers are initially located below the cable tray, thus ensuring that the cables on the cable tray are better attached to the cable tray.

Limiting plates are provided on the drive shaft 204 and on the outer side of each guide wheel 206 to prevent the drive shaft 204 from detaching from the two guide wheels 206. A limiting block 207, located above the end of the drive shaft 204, is fixed to the placement platform 203 by screws. The limiting block 207 prevents the drive shaft 204 from detaching from the top of the placement platform and is detachably connected for easy replacement of the cable reel.

[0020] A cable limiter 4 is installed between the cable laying structure 2 and the cable bridge structure 3. The cable limiter 4 includes a support column 401 and a ring 402 fixedly installed above the support column 401. Several bullseye bearings 403 are evenly distributed circumferentially on the inner wall of the ring 402. The distance between two adjacent bullseye bearings 403 is less than the outer diameter of the cable. The height of the ring 402 is lower than that of the cable tray 5. This prevents the cable from being squeezed between two bullseye bearings 403. The support column 401 is fixed to the platform 101 of the scissor lift platform 1 or to the base 201. The bullseye bearings 403 are existing technology, and their specific structure will not be described in detail here.

[0021] The scissor lift platform 1, employing existing technology, generally includes a frame 104 with drive wheels 105, a scissor bracket 103 mounted on the frame 104, a telescopic rod 102 that drives the scissor bracket 103 to rise and fall, and a platform 101 mounted on the scissor bracket 103. The telescopic rod 102 is generally a hydraulic rod. Appropriate safety railings should be installed around the platform 101 according to actual conditions to ensure the safety of personnel using the platform 101.

[0022] How to use: The coiled cable reel 205 is placed on the drive shaft 204 and secured with screws. One end of the cable is passed through the ring 402 and placed between the vertical roller 318 and the two horizontal rollers 320, and fixed to the cable tray 5 with a wire clamp. The scissor lift platform 1 moves along the direction of the cable tray 5 to gradually lay the cable. The drive rod 307 is initially in a horizontal position and the roller 308 is in contact with the small sector 31001, while the ball 324 is in contact with the outer end face of the limiting plate 311.

[0023] Once the cable has moved to the designated position, the motor 312 is started. The motor 312 drives the rotating shaft 309 to rotate through the transmission mechanism. The rotation drives the cam 310 and the limit plate 311 to rotate. When the roller 308 contacts the large sector 31002 on the cam 310, the ball 324 contacts the sector boss 31101. At this time, the drive plate is lifted and moves towards the cable tray 5. The cable is located above the cable tray 5 on the vertical roller 318 and the two horizontal rollers 320, which facilitates the laying of the cable.
