Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically to a cable transfer device for power construction. Background Technology

[0002] The transport of cable reels is a crucial step in power construction. To ensure ease of handling, they are typically placed horizontally. However, during transport, especially in complex road conditions such as mountainous areas or slopes, vehicle bumps and tilting can easily cause the cable reels to roll or shift, posing significant safety hazards. Currently, multiple ropes are commonly used to secure the cable reels on-site, but the effectiveness of this method largely depends on the experience and responsibility of the transport workers; the process is cumbersome and prone to safety oversights. To improve the safety and efficiency of transport, specialized truck chassis for cable reel transport are available on the market, but these chassis are generally expensive, placing a considerable financial burden on many construction companies, especially small and medium-sized enterprises.

[0022] The container chassis 100 has a metal tubular frame structure and is equipped with container-style connecting corner brackets at the corners, which facilitates anchoring with existing container transport flatbed trucks.

[0023] As attached Figure 1 As shown in Figure 2, the front limiting rod assembly 200 includes several vertical fixing rods 210 and connecting crossbars 220. The vertical fixing rods 210 are vertically arranged at one end of the container chassis. Each vertical fixing rod 210 has a vertical trapezoidal slot 211 on the side away from the front of the vehicle, used to engage the edge of the cable reel. Its trapezoidal cross-sectional structure can be adapted to achieve good fixing of reel edges of different thicknesses. The vertical fixing rods 210 are arranged in pairs, connected by several connecting crossbars 220 to improve stability.

[0024] The roller slide rail assembly 300 includes several roller slide rails 310. The roller slide rails 310 are fixed on the container chassis 100, and two roller slide rails 310 are arranged in parallel and aligned with the vertical fixing rod 210. The roller slide rails 310 are U-shaped steel materials, including side plates and bottom plates. In use, the edge of the cable reel is pushed into the roller slide rail 310.

[0025] The locking unit 400 is detachably mounted on the roller slide rail 310 and works in conjunction with the vertical fixing rod 210 or the locking unit 400 to achieve initial fixation of the cable reel.

[0026] Several fixing rods 530 are provided on the outside of the roller slide rail 310. A ratchet locking structure can be provided on the fixing rods 530. Such structures are common in the field of truck cable locking.

[0027] As attached Figure 1 , 6 As shown, the fixed cable assembly 500 includes a central cable section 510 and edge cable sections 520, with the central cable section 510 and the two edge cable sections 520 forming a double Y-shape. Specifically, the center of the edge cable sections 520 is connected to both ends of the central cable section 510. Pull rings are provided on both sides of the edge cable sections 520 for connecting with the cable. This structure facilitates the fixing of the cable reel.

[0028] As attached Figure 3 As shown in Figures 4 and 5, the locking unit 400 includes two side latching portions 410 and a central locking portion 420. The latching portions 410 are disposed on both sides of the central locking portion 420. A vertical trapezoidal locking unit slot 411 is provided in the central area of ​​the end of the latching portion 410 for locking the edge of the cable reel into it. Its trapezoidal cross-sectional structure can be adapted to the edge of the reel of different thicknesses to achieve a good fixing effect.

[0029] The width of the locking part 420 of the central locking part 410 is equal to or slightly smaller than the width of the slide groove of the roller slide rail 310.

[0030] The central locking part 420 includes a central block 421, a side plate 422, a locking screw 423, a shaped push block 424, a locking block 425, and a spring 426.

[0031] The width of the central block 421 is equal to or slightly smaller than the width of the slide groove of the roller slide rail 310. Side plates 422 are provided on both sides, and there is a gap between the side plates and the central block 421. The gap between the side plates and the central block 421 is equal to or slightly larger than the thickness of the side plates of the roller slide rail 310.

[0032] A groove 421a is provided in the lower center of the central block 421, extending through the side of the central block 421. A threaded hole is provided in the center of the groove. The locking screw 423 has threads on its outer side, which mate with the threaded hole. To improve the connection strength, a reinforcing nut 427 is provided on the outer side of the threaded hole. An irregularly shaped push block 424 is fixed to the end of the locking screw 423 that extends into the groove 421a. The irregularly shaped push block 424 is elliptical.

[0033] The top of the locking screw 423 is provided with a hexagonal tightening part, which cooperates with the hexagonal sleeve to realize the tightening of the locking screw 423.

[0034] There are two locking blocks 425, which are arranged in parallel on both sides of the irregular push block 424. The two locking blocks 425 can extend out of the groove 421a under the push of the irregular push block. The two locking blocks 425 are provided with limit protrusions on both sides, which cooperate with the groove of the groove 421a on the side of the central block 421 to realize the limit of the reciprocating movement of the locking blocks 425. A spring 426 is provided between the two locking blocks 425.

[0035] The central locking part 420 also includes a base plate 428 for closing the groove 421a. A protrusion 4281 is provided in the center of the base plate 428, and its side is parallel to the side of the central block. The protrusion is used to define the position of the locking block 425 and to keep it in a parallel position.

[0036] In use, the locking screw 423 is turned by a specific wrench, which drives the irregular push block 424 to rotate, pushing the locking block 425 out of the groove 421a and abutting against the side plate of the roller slide rail 310, thereby fixing the locking unit 400.

[0037] In use, place both ends of the cable reel on the roller guide rail and push the cable reel to the front position manually or mechanically. The locking unit initially secures the cable reel. Subsequently, a secondary locking is performed using the fixing steel cable assembly 500.

[0038] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
