Description

Technical Field

[0001] This utility model relates to the field of power installation technology, specifically to a wire laying device for power installation. Background Technology

[0002] In power installation projects, the wire laying device is a key piece of equipment, and its performance directly affects the construction efficiency and quality.

[0003] Currently, traditional cable laying devices mostly adopt a single-station fixed clamping structure, which can only lay out single bundles of cables, making it difficult to meet the needs of simultaneous laying of multiple cable bundles in large-scale power construction.

[0004] Furthermore, the clamping mechanisms of existing devices often lack adaptive adjustment capabilities. When dealing with wire coils of different specifications, frequent clamp changes or manual adjustments are required, which is not only cumbersome but also prone to clamping instability, affecting the accuracy and efficiency of wire feeding. In terms of the guiding structure, most wire feeding devices are only equipped with a single guide wheel, which cannot effectively solve the problems of directional dispersion and tangling when feeding multiple wire bundles simultaneously, increasing the workload and construction risks of manually sorting wire bundles.

[0005] As the scale of power engineering projects continues to expand, higher requirements are placed on the performance of wire laying devices, such as multi-wire bundle synchronous operation, adaptive adjustment, precise guidance, and flexible movement. There is an urgent need to develop new wire laying devices to overcome the shortcomings of existing technologies. Utility Model Content

[0006] The purpose of this invention is to provide a wire-laying device for power installation, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cable-laying device for power installation includes a base, a support frame fixedly mounted on the upper surface of the base, two shafts rotatably mounted through the support frame, two inner baffles fixedly mounted on the middle section of each shaft, the two inner baffles being located on the left and right sides of the support frame respectively, and an adaptive inner clamping device being installed on the side of each inner baffle away from the support frame, and outer baffles being mounted on both the left and right ends of the shaft, with locking nuts screwed onto the outer surfaces of both ends of the shaft, the locking nuts being located on the side of the outer baffle away from the adaptive inner clamping device.

[0009] Preferably, each of the adaptive inner clamping devices includes two sleeve blocks. The sleeve block near the inner baffle is fixedly installed on the outer surface of the shaft, and the other sleeve block is slidably sleeved on the outer surface of the shaft. The outer surface of the sleeve block is provided with at least three mounting grooves circumferentially and evenly spaced. Each mounting groove is rotatably installed with a connecting rod through a rotating shaft, and an inner liner is rotatably installed between the two corresponding connecting rods on the left and right sides.

[0010] Preferably, a return spring is fixedly installed between the two sleeve blocks, and the return spring is sleeved on the outside of the shaft.

[0011] Preferably, four inner rotor bearings are welded and fixedly installed inside the frame. The four inner rotor bearings are arranged in a rectangular distribution inside the frame. The shaft passes through two corresponding inner rotor bearings on the left and right, and there is an interference fit between the shaft and the corresponding inner rotor bearing.

[0012] Preferably, the front surface of the support frame is provided with a T-shaped support rod, a spacer block is fixedly installed between the rear surface of the support rod and the support frame, and two guide rings are fixedly installed on the outer surfaces of both ends of the support rod.

[0013] Preferably, the front surface of the support frame is provided with a T-shaped support rod, a spacer block is fixedly installed between the rear surface of the support rod and the support frame, and two guide rings are fixedly installed on the outer surfaces of both ends of the support rod.

[0014] Preferably, four wire rings are fixedly installed circumferentially at equal intervals on the outer surface of the front end of the support rod.

[0015] Preferably, auxiliary wheels are rotatably mounted on both the left and right sides of the rear end of the base, and support legs are symmetrically fixedly mounted on the front end of the lower surface of the base. The lower surface of the support legs and the lower surface of the auxiliary wheels are at the same horizontal plane, and a handrail is fixedly mounted on the rear surface of the stand.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, by incorporating multiple adaptive internal clamping devices on the shaft, can simultaneously secure four bundles of coiled wire, enabling synchronous unloading of multiple wire bundles and significantly improving construction efficiency. Furthermore, through a sleeve block and connecting rod transmission structure, the position of the inner liner can be automatically adjusted according to the specifications of the wire coils, achieving stable clamping of coils of different thicknesses and diameters. This avoids the drawbacks of traditional devices requiring frequent clamp changes, reduces manual operation costs, and enhances the versatility and applicability of the device.

[0018] This utility model, by setting a T-shaped support rod and integrating a guide ring and a wire-gathering ring combination structure, can first guide the wires precisely through the guide ring, and then naturally converge through the wire-gathering ring. While avoiding excessive compression of the wire harness, it effectively solves the problem of the dispersed traction direction of multiple wire harnesses, and can significantly reduce the phenomenon of wire harness jamming and tangling during the wire laying process, improve the efficiency of wire laying and the regularity of wire harness laying, and reduce construction risks.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution:

[0027] A wire-laying device for electrical installation, such as Figure 1 As shown, the device includes a base 1, on the upper surface of which a support frame 2 is welded and fixedly installed. Two shafts 3 are rotatably installed through the support frame 2. Two inner baffles 31 are fixedly installed on the middle section of each shaft 3. The two inner baffles 31 are located on the left and right sides of the support frame 2, respectively. An adaptive inner clamping device 4 is installed on the side of the inner baffles 31 away from the support frame 2. Outer baffles 5 are installed on both the left and right ends of the shafts 3, and locking nuts 6 are screwed onto the outer surfaces of both ends of the shafts 3. The locking nuts 6 are located on the side of the outer baffles 5 away from the adaptive inner clamping device 4.

[0028] It should be noted that, in combination Figure 4 and Figure 5As shown, the adaptive inner clamping device 4 includes two sleeve blocks 41. The sleeve block 41 near the inner baffle 31 is welded and fixedly installed on the outer surface of the shaft 3. The other sleeve block 41 is slidably sleeved on the outer surface of the shaft 3. The outer surface of the sleeve block 41 is provided with at least three mounting grooves 411 circumferentially and equidistantly. A connecting rod 42 is rotatably installed in each mounting groove 411 through a rotating shaft. An inner liner 43 is rotatably installed between the two corresponding connecting rods 42 on the left and right. The inner liner 43 is a metal part. In the actual production process, the length of the inner liner 43 is greater than the thickness of the wire coil to ensure the stability when clamping the first coil from the inside (the inner liner 43 in the attached figure is only used for view reference and does not represent the actual production size).

[0029] During use, the coiled wire is fitted onto the outside of the adaptive inner clamping device 4. First, the inner liner 43 at the upper part of the adaptive inner clamping device 4 supports the coiled wire. Then, the outer baffle 5 is fitted onto the outer surface of the shaft 3 from the end of the shaft 3. Next, the locking nut 6 is connected to the end of the shaft 3 by a thread and continuously tightened. The locking nut 6 can be used to push the outer baffle 5 towards the adaptive inner clamping device 4. The outer baffle 5 causes the sleeve block 41, which is slidably set on the shaft 3, to move towards the fixed sleeve block 41. Then, the inner liner 43 is lifted outward by the connecting rod 42, thereby clamping and fixing the inner side of the coiled wire. This allows the wire to be rotated with the shaft 3 to complete the manual traction and wire release operation.

[0030] In practical applications, up to four bundles of coiled wire can be respectively fitted onto the corresponding adaptive inner clamping device 4 for fixation. With the rotation of the shaft 3, the four bundles of wire can be manually pulled and unloaded simultaneously. Compared with existing technologies, this device, through the cooperation of the sleeve block 41 and the connecting rod 42, enables the adaptive adjustment of the inner liner 43, allowing for stable clamping of coiled wire of different specifications. This solves the problem of low efficiency in traditional single-station unloading, enabling the fixing and unloading of multiple bundles of wire, effectively reducing manual operation costs, and meeting the needs of synchronous unloading of multiple wire bundles in industrial applications.

[0031] In addition, after the wire laying operation is completed, in order to achieve quick repositioning of the inner liner 43 to facilitate the installation of the next roll of wire, combined with... Figure 4 and Figure 5 As shown, a return spring 44 is fixedly installed between the two sleeve blocks 41. The return spring 44 is sleeved on the outside of the shaft 3. When the outer baffle 5 is removed, the external thrust acting on the sliding sleeve block 41 disappears. The return spring 44 drives the sliding sleeve block 41 to move to the initial position through the elastic restoring force, and then drives the inner liner 43 to reset inward through the connecting rod 42, thus completing the automatic return of the clamping mechanism. The setting of the return spring 44 realizes the passive automatic reset of the clamping mechanism, which does not require an additional power source, simplifies the operation process, shortens the roll changing time, and improves the ease of use and continuous operation capability of the equipment.

[0032] Combination Figure 1 , Figure 3 and Figure 4 As shown, four inner rotor bearings 21 are welded and fixedly installed inside the frame 2. The four inner rotor bearings 21 are arranged in a rectangular distribution inside the frame 2. The shaft 3 passes through two corresponding inner rotor bearings 21 on the left and right, and the shaft 3 and the corresponding inner rotor bearing 21 are interference-fitted, thereby realizing the rotatable installation of the shaft 3 inside the frame 2.

[0033] In addition, in the scenario of simultaneous laying of four bundles of wires, in order to solve the problem of dispersed traction direction of multiple wire bundles, a T-shaped support rod 7 is set on the front surface of the support frame 2. A spacer block is welded and fixed between the rear surface of the support rod 7 and the support frame 2. By welding the spacer block, it is extended forward to optimize the spatial layout. Two guide rings 71 are fixedly installed on the outer surface of both ends of the support rod 7, and four wire gathering rings 72 are fixedly installed circumferentially at equal intervals on the outer surface of the front end of the support rod 7. The outer surfaces of two adjacent wire gathering rings 72 are attached together.

[0034] During the cable laying operation, the wires first pass through the guide ring 71 for initial guidance, and then converge through the wire-gathering ring 72. This design breaks through the limitations of the traditional single guide structure. Compared with existing technologies, it eliminates the need for repeated manual adjustments to the cable bundle direction. The guide ring 71 achieves precise guidance of a single wire, and the combined structure of the wire-gathering ring 72 enables the natural convergence of multiple cable bundles while avoiding excessive compression and tangling. This effectively reduces cable bundle jamming and tangling during the laying process, significantly improving cable laying efficiency and the neatness of cable bundle installation.

[0035] Finally, to improve the mobility of the device, such as Figure 1 As shown, auxiliary wheels 11 are rotatably installed on both the left and right sides of the rear end of the base 1. Support legs 12 are symmetrically fixedly installed on the front end of the lower surface of the base 1. The lower surface of the support legs 12 and the lower surface of the auxiliary wheels 11 are on the same horizontal plane. Handrails 22 are fixedly installed on the rear surface of the stand 2.

[0036] When the device is stationary, the support leg 12 is in contact with the ground to ensure the stability of the equipment; when it needs to be moved, the operator can press down on the handle 22 and use the auxiliary wheel 11 as a fulcrum to flip the device, so that the support leg 12 is off the ground, and the device can be easily pushed to move. A single person can complete the short-distance transport of the device.
