Description

Technical Field

[0001] The present invention relates to the technical field of cable installation, and particularly relates to an auxiliary tooling for cable laying. Background Art

[0002] The installation and laying of cables is a crucial link in electrical engineering. It involves safely and effectively laying power or communication cables from one point to another. To ensure the stable operation of the system and extend the service life of the cables, the cables need to be laid correctly according to requirements. During the work process, sometimes it is necessary to install and lay cables in a narrow space (such as a cable trench). The narrow working environment will limit the use of cable laying machines and manual operations, increasing the difficulty of cable laying and affecting the laying efficiency.

[0003] The patent application document with the publication number CN119070206A discloses a cable trench support structure and a cable laying method. The cable trench support structure includes a fixed frame fixedly connected to the side wall of the cable trench. A plurality of clamping grooves are formed in the inner wall of the fixed frame along the height direction; a sliding rod is slidably connected to the fixed frame along the height direction. A support rod for supporting the cable is fixed to the side wall of the sliding rod; a clamping component is arranged in the sliding rod. The clamping end of the clamping component can be clamped in the clamping groove to relatively fix the sliding rod and the fixed frame. The clamping component can stop the downward movement of the sliding rod; an unlocking component is arranged in the sliding rod for unlocking the clamping component. The operating end of the unlocking component is located outside the sliding rod. A second operating hole for the same cross bar to pass through is formed in a plurality of the sliding rods.

[0004] The cable trench support structure provided by the above patent application document reduces the obstruction when the cable is fixed to the support rod by setting the support rod and the sliding rod in a detachable connection manner. When laying the cable, the support rod located in the upper layer is disassembled, and the cable of the lowermost support rod is laid first. At this time, due to the influence of the upper support rod, the laying efficiency of the cable is further improved; after laying the cable of the lower support rod, the upper support rod is connected to the sliding rod, and the laying of the cable on the upper support rod continues. This scheme can reduce the influence of the upper support rod on cable laying.

[0005] During the cable laying process, usually multiple cables need to be laid on each layer. To avoid the cables from being entangled and crossed, the cables need to be straightened and then fixed with wire clips. When laying the cable with the cable trench support structure provided by the above scheme, although the influence of the upper support rod on the laying operation is avoided, it is still necessary to manually lay and fix the bundled cables neatly on the support rod. These operations are still greatly limited in the cable trench. Summary of the Invention

[0006] The present invention provides an auxiliary tool for cable laying, aiming to solve the problem in the related art that when a cable laying device is laying cables in a cable trench, the cable laying work is difficult due to the influence of the operating space and the cable laying efficiency is affected.

[0007] The present invention provides an auxiliary tool for cable laying, comprising a frame, a mounting plate is provided on the frame for lifting, a guide and a moving mechanism are provided on the frame, the length direction of the frame is parallel to the wiring direction of the cable, the guide reciprocates and slides with the frame along the length direction of the frame, a plurality of guide grooves are provided on the guide, which are opposite to and slide with each cable one by one, with the side facing the wiring direction as the front side, the moving mechanism is located at the rear side of the guide, and reciprocates and slides with the frame along the length direction of the frame;

[0008] The moving mechanism includes a bracket and a plurality of fixing parts, a cavity is formed inside the bracket, each of the fixing parts is longitudinally stacked inside the bracket and longitudinally slidably cooperates with the side wall of the bracket, each of the fixing parts is elastically limited and cooperates with the side wall of the bracket at the lower end inside the bracket, and a plurality of fixing grooves are provided on the upper and lower ends of the fixing parts, each of the fixing grooves corresponds to each cable of the upper and lower layers respectively, and the lower end of the fixing part is snap-fitted with the upper end of the fixing part of the lower layer.

[0009] The difficulty of laying cables in the cable trench is reduced. The guide member and the moving mechanism slide back and forth along the wiring direction on the mounting plate. During the sliding process of the guide member, the crossed and entangled cables are combed out and the cables are arranged neatly. The moving mechanism lowers the fixing members at intervals behind the guide member, and during the movement, the upper fixing members of the cable are plugged and fixed with the lower fixing members of the cable, thereby completing the automatic fixing operation of the cable, greatly facilitating the cable arrangement and fixing operations, and effectively improving the laying efficiency and laying effect of the cable.

[0010] Preferably, a slot with a closed front end is provided on the upper side of the fixing piece, a stop block is provided at the rear end of the slot for longitudinal sliding, the stop block is elastically connected to the fixing piece, a block is fixed at the lower end of the fixing piece, the block is longitudinally opposite to the slot, and the block is inserted into the slot from the rear end of the slot.

[0011] It is convenient to automatically fix the cable during the cable laying process. When the bracket moves to be opposite to the lower fixing piece of the cable, the lowermost fixing piece in the bracket is inserted into the slot of the lower fixing piece of the cable through the clamping block. When the two fixing pieces are relatively clamped, the upper fixing piece moves forward, and the clamping block squeezes the stopper at the rear end of the slot to move downward. When the front end of the clamping block fits with the front end of the slot, the upper and lower fixing pieces are docked, and the stopper at the rear end of the slot is reset to further limit the position of the upper fixing piece, thereby improving the cable laying efficiency.

[0012] Preferably, a cylinder is further provided on the bracket, and the extending end of the cylinder is in movable abutment with the uppermost fixing member inside the bracket.

[0013] Preferably, the rear end face of the stopper inclines forward from bottom to top, and the lower end of the stopper is elastically connected to the fixing member through a spring.

[0014] Preferably, a limiting block is elastically connected to the lower side of the side wall of the bracket. The front end face of the limiting block inclines backward along the direction away from the side wall of the bracket. A limiting groove is provided at the end of the fixing member that slidably fits with the bracket, and the limiting block is movably inserted and matched with the limiting groove.

[0015] Ensure that each fixing member in the bracket is fixed to each fixing member on the lower side of the cable in sequence. The cylinder pushes the fixing members in the bracket to move downward as a whole, and then pushes a new fixing member to move to the lower end of the bracket. Through the cooperation of the limiting groove and the limiting block at the lower end of the bracket, when the moving mechanism moves forward along the length direction of the mounting plate, each fixing member in the bracket is matched with each fixing member that has been fixed on the lower side of the cable one by one and automatically completes the plugging and fixing, realizing the neat laying and fixing operation of the cable.

[0016] Preferably, an arc-shaped gasket is provided in the fixing groove on the upper side of the fixing member. The gasket is slidably matched with the fixing groove along the wiring direction, and the gasket is in frictional contact with the cable.

[0017] By providing the arc-shaped gasket, on the one hand, the fixing strength between the fixing member and the cable can be improved, and on the other hand, the docking of the two fixing members is not affected. When the upper fixing member moves with the bracket to be close to the lower fixing member, the upper and lower fixing members gradually start to be plugged. The frictional force generated between the upper and lower fixing members and the cable gradually increases. Under the action of the frictional force, the gasket slides in the fixing groove of the lower fixing member along with the cable, avoiding excessive frictional force between the cable and the fixing groove from blocking the docking of the two fixing members.

[0018] Preferably, the distance between two adjacent guiding grooves on the guiding member is greater than the distance between two adjacent fixing grooves on the fixing member.

[0019] Preferably, a fixing portion is snap-fitted on the guiding member, and a plurality of grooves corresponding to each of the guiding grooves are provided on the fixing portion.

[0020] Preferably, a rotating portion is rotatably provided in both the groove and the guiding groove, and the rotating portion is in rolling frictional contact with the cable.

[0021] It is convenient for the guiding member to arrange and comb the cable. By providing the rotating portion in the guiding groove and the groove, the frictional force when the guiding member slides relative to the cable is reduced, and at the same time, the wear on the surface layer of the cable is reduced.

[0022] Preferably, a plurality of sets of lifting mechanisms that work synchronously are provided on the frame body. The lifting mechanism includes a driving source and a lead screw. The driving source is installed on the frame body, the driving end of the driving source is fixed to the lead screw, and the mounting plate is in threaded cooperation with the lead screw.

[0023] The beneficial effects of the present invention are as follows: The difficulty of laying cables in the cable trench is reduced. The guiding member and the moving mechanism reciprocally slide along the wiring direction on the mounting plate. During the sliding process of the guiding member, the crossed and entangled cables are combed out, and the cables are neatly arranged. The moving mechanism intermittently lowers fixing members at the rear side of the guiding member, and during the moving process, the upper fixing member of the cable is inserted and cooperated with the lower fixing member of the cable for fixing, completing the automatic fixing operation of the cable, greatly facilitating the cable routing and fixing operations, and effectively improving the laying efficiency and laying effect of the cable.

[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0032] As Figure 1 and Figure 2As shown in the figure, the auxiliary tooling for cable laying of the present invention includes a frame body 1. An installation plate 13, a guiding member 2 and a moving mechanism are provided on the frame body 1. When laying a cable 4 in a cable trench, the frame body 1 is directly placed into the cable trench. The cable 4 to be laid is laid layer by layer on the installation plate 13. To facilitate the layer-by-layer laying of the cable 4, the installation plate 13 is in lifting cooperation with the frame body 1. Specifically, the installation plate 13 can be driven to lift relative to the frame body 1 through a lifting mechanism. After each layer of cable 4 is laid, the installation plate 13 is driven to descend a certain distance, and then the cable 4 is continued to be laid on the upper layer of the laid cable layer until all the cables 4 are laid. Taking the side facing the wiring direction as the front side, the length direction of the frame body 1 is parallel to the wiring direction. The guiding member 2 is located in front of the moving mechanism. Both the moving mechanism and the guiding member 2 are slidably engaged with the frame body 1 along the length direction of the frame body 1. When the moving mechanism and the guiding member 2 slide relative to the frame body 1, the guiding member 2 straightens and neatly arranges the cable 4 in front of the moving mechanism, and the moving mechanism fixes the cable 4 at intervals behind the guiding member 2.

[0033] As Figure 5 shown, a slide rail is provided on the frame body 1. Two ends of the guiding member 2 are provided with a first chute 24 slidably engaged with the slide rail. A plurality of guiding grooves 22 are provided at the upper end of the guiding member 2 and are slidably engaged with each cable 4 one by one. When the guiding member 2 straightens and arranges the cable 4 in front of the moving mechanism, each cable 4 needs to be correspondingly placed into each guiding groove 22 one by one. A fixing portion 21 is also buckled on the guiding member 2. A plurality of grooves corresponding to each guiding groove 22 one by one are provided on the fixing portion 21. After each cable 4 in the same layer is placed into each guiding groove 22 one by one, the fixing portion 21 is buckled to further limit the positions of each cable 4. When the guiding member 2 slides along the frame body 1, the relatively scattered cable 4 is straightened into a neat state. To further reduce the frictional force between the guiding member 2 and the cable 4 when the guiding member 2 slides relative to the frame body 1, the radii of each guiding groove 22 and the grooves on the fixing portion 21 are both larger than the radius of the cable 4, and a rotating portion 23 is rotatably provided in the groove and the guiding groove 22. The rotating portion 23 is in rolling friction contact with the cable 4. In addition, to further reduce the resistance generated during the process of the guiding member 2 combing the cable 4 and fully disperse the intersecting cables 4, the distance between two adjacent guiding grooves 22 on the guiding member 2 is slightly larger than the distance between two adjacent fixing grooves 311 on the fixing member 31.

[0034] As Figures 2 to 4As shown, the moving mechanism includes a bracket 3 and a plurality of fixing members 31. The bracket 3 and the guiding member 2 can be detachably connected by means of clamping or threaded fitting. A second sliding groove for sliding cooperation with the track is provided at the lower end of the bracket 3. When laying the cable 4, an operator can push the upper part of the bracket 3, so that the bracket 3 and the guiding member 2 slide along the slide rail of the frame body 1. A cavity is formed inside the bracket 3. The fixing members 31 are longitudinally stacked inside the bracket 3 and are longitudinally slidably fitted with the side wall of the bracket 3. The lower ends of the fixing members 31 are elastically limited and fitted with the side wall of the bracket 3 inside the bracket 3. A plurality of fixing grooves 311 are provided at the upper and lower ends of the fixing member 31, and the fixing grooves 311 respectively correspond to the cables 4 in the upper and lower layers one by one. The lower end of the fixing member 31 is clamped and fitted with the upper end of the lower fixing member 31.

[0035] A limiting block 32 is elastically connected to the lower side of the side wall of the bracket 3. The front end face of the limiting block 32 is inclined backward along the direction away from the side wall of the bracket 3. A limiting groove 316 is provided at the end of the fixing member 31 that slidably fits with the bracket 3. The limiting block 32 is movably inserted and fitted with the limiting groove 316. A cylinder is also provided on the bracket 3. The extending end of the cylinder extends into the inside of the bracket 3 and is movably abutted against the uppermost fixing member 31 inside the bracket 3. The lowermost fixing member 31 of the bracket 3 is movably clamped with the limiting block 32 through the limiting groove 316. A clamping groove 314 with a closed front end is provided on the upper side of the fixing member 31. A blocking block 315 is longitudinally slidably provided at the rear end of the clamping groove 314. The blocking block 315 is elastically connected to the fixing member 31. The rear end face of the blocking block 315 is inclined forward from bottom to top. The lower end of the blocking block 315 is elastically connected to the fixing member 31 through a spring. A clamping block 313 is fixed at the lower end of the fixing member 31. The clamping block 313 is longitudinally opposite to the clamping groove 314. The clamping block 313 is inserted into the clamping groove 314 from the rear end of the clamping groove 314. The shapes of the clamping block 313 and the clamping groove 314 are the same. The clamping block 313 and the clamping groove 314 can be a cross-shaped structure to ensure that when the fixing members 31 are longitudinally stacked in the bracket 3, the clamping block 313 of the upper fixing member 31 will not be stuck in the clamping groove 314 of the lower fixing member 31.

[0036] Before laying the first layer of cables 4 on the mounting plate 13, first fix several fixing members 31 at intervals along the length direction of the mounting plate 13. The fixing members 31 directly fixed to the mounting plate 13 can be provided with fixing grooves 311 only on the upper side. Each fixing member 31 can be detachably connected to the mounting plate 13 by screws. Then, each cable 4 is sequentially inserted into the mounting grooves of the last fixing member 31 on the mounting plate 13, and the fixing grooves 311 on the fixing members 31 in the bracket 3 are kept in one-to-one correspondence with each cable 4 longitudinally. The guiding member 2 is slidably engaged with each cable 4 one by one through each guiding groove 22 on the front side of the bracket 3. Then, the bracket 3 is pushed to move. The guiding member 2 moves synchronously with the bracket 3 on the front side of the bracket 3 and combs the cables 4 on the front side of the bracket 3. When the bracket 3 moves to be opposite to the fixing member 31 on the lower side of the cable 4, the lowermost fixing member 31 in the bracket 3 is snapped into the slot 314 of the fixing member 31 on the lower side of the cable 4 through the engaging block 313. When the two fixing members 31 are relatively snapped together, the upper fixing member 31 moves forward, and the engaging block 313 squeezes the stopper 315 at the rear end of the slot 314 to move downward. When the front end of the engaging block 313 fits with the front end of the slot 314, the upper and lower fixing members 31 complete the docking. The stopper 315 at the rear end of the slot 314 resets to further limit the position of the upper fixing member 31. Thus, the automatic snap connection and fixation of the upper and lower two fixing members 31 are completed. Then, the bracket 3 continues to move forward. The lowermost fixing member 31 in the bracket 3 is blocked by the fixing member 31 on its lower side and does not move forward with the bracket 3. And the limiting groove 316 of the fixing member 31 is disengaged from the limiting block 32 at the lower end of the bracket 3. The air cylinder pushes the fixing members 31 in the bracket 3 to move downward as a whole, and a new fixing member 31 is pushed to move to the lower end of the bracket 3 again and is inserted and matched with the limiting block 32 at the lower end of the bracket 3 through the limiting groove 316. When the moving mechanism moves from the rear to the front along the length direction of the mounting plate 13, the fixing members 31 in the bracket 3 are matched with the fixing members 31 that have been fixed on the lower side of the cable 4 one by one and automatically complete the insertion and fixation, realizing the neat laying and fixing operation of the cable 4.

[0037] To ensure the clamping strength of the two fixing parts 31 in the longitudinal plug-in fit for the cable 4 and improve the stability of cable 4 laying, an arc-shaped gasket 312 is provided in the fixing groove 311 on the upper side of the fixing part 31. The gasket 312 is in sliding fit with the fixing groove 311 along the wiring direction. The gasket 312 is in frictional contact with the cable 4. The diameter of the fixing groove 311 is the same as or slightly smaller than that of the cable 4, so that after the two fixing parts 31 are longitudinally butted, the fixing groove 311 can firmly clamp the cable 4. By providing the arc-shaped gasket 312, on the one hand, the fixing strength between the fixing part 31 and the cable 4 can be improved, and on the other hand, the butt joint of the two fixing parts 31 is not affected. When the upper fixing part 31 moves along with the bracket 3 to be close to the lower fixing part 31, the upper and lower fixing parts 31 gradually start to be inserted. The frictional force generated between the upper and lower fixing parts 31 and the cable 4 gradually increases. Under the action of the frictional force, the gasket 312 slides in the fixing groove 311 of the lower fixing part 31 along with the cable 4, avoiding excessive frictional force between the cable 4 and the fixing groove 311 from blocking the butt joint of the two fixing parts 31.

[0038] During the laying process of the cable 4, to facilitate the laying of each layer of the cable 4, after each layer of cable 4 laying work is completed, the lifting mechanism drives the mounting plate 13 to move downward relative to the frame body 1 by a certain distance. The lifting mechanism includes a driving source 11 and a lead screw 12. The driving source 11 is installed on the frame body 1. The driving source 11 can be a motor. The driving end of the driving source 11 is fixed to the lead screw 12. The mounting plate 13 is in threaded fit with the lead screw 12. Four groups of lifting mechanisms can be provided. The four groups of lifting mechanisms are respectively arranged at the four corners of the frame body 1, and the four groups of lifting mechanisms work synchronously. In other embodiments, the mounting plate 13 can also be driven to move up and down relative to the frame body 1 by a plurality of cylinders.

[0039] The cable laying auxiliary tooling provided by the present invention facilitates the layer-by-layer laying of cables in the cable trench, and through the cooperation of the moving mechanism and the guiding member, automatically combs, arranges and fixes the cables, reduces the difficulty of cable laying and fixing during the cable laying process, and improves the cable laying efficiency.
