Description

Technical Field

[0001] This utility model relates to the field of wire feeding frame technology. Specifically, it is an integrated wire feeding frame. Background Technology

[0002] With the expansion of power system construction and the increasing demand for power grid upgrades and renovations, the efficiency and quality requirements for transmission line construction have significantly increased. As a crucial piece of equipment for transmission line erection, the performance of the conductor laying frame directly impacts construction safety, economy, and ease of use.

[0003] The cable reel stand is an important auxiliary device in the construction of tensioning equipment, and it is also a widely used and in-demand tool in tension cable reel projects. Its main function during tension cable reeling is to support the balanced rotation of the conductor reel to output the conductor, and to generate a continuously adjustable tail tension of 0-3kN under the action of a brake or hydraulic motor. Due to the large differences in cable reel diameters and inconsistent apertures, there are many types of cable reel stands on the market, generally divided into integral cable reel stands and assembled cable reel stands. With cable reel diameters ranging from 500-4000mm and apertures from 56-160mm, assembled cable reel stands on the market come in various models such as 3T, 5T, 8T, 10T, 12T, 15T, 20T, and 22T, depending on the rated load. The large variety of models presents significant challenges in the storage, classification, and management of multiple cable reel stands. They also require a large footprint and incur high management and maintenance costs.

[0004] Their structures are identical, consisting of a hydraulic motor, a spool shaft, a tripod, a base, and an adjusting support rod. During operation, the spool shaft is inserted into the spool hole and fixed. When reeling in the line, the hydraulic motor drives the spool shaft to rotate, which in turn drives the spool to rotate, thus reeling in the line. When unloading the line, the guide wire pulls the spool to rotate, and the spool shaft, driven by a dial shaft, rotates the spool shaft. The spool shaft forces the hydraulic motor to rotate with some resistance, preventing the spool from rotating too quickly due to inertia, which could lead to excessive or rapid unloading of line.

[0005] Different models of wire reel stands operate on the same principle; the difference lies in the diameter and width of the wire reels they are suitable for. Therefore, if different types of wire reel stands could be integrated without affecting the original structure, allowing for the integration of two or more types of wire reel supports, it would significantly reduce storage, transportation, and management costs. Furthermore, through lightweight and integrated design, it could reduce manpower and lower construction costs. However, no relevant public reports have been found to date. Summary of the Invention

[0006] Therefore, the technical problem to be solved by this utility model is to provide an integrated wire feeding frame, which can effectively solve the problem of many types of wire feeding frames and low integration.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An integrated wire feeding frame includes a tripod, a base frame, and an adjusting support rod. The tripod and the adjusting support rod are fixed with a groove at their ends. The wire spool is mounted in the groove via a bearing. A support mechanism is installed in the groove. A rotating fitting is mounted outside the bearing of the wire spool. The rotating fitting is placed in the support mechanism and fixed.

[0009] Preferably, the above-mentioned support mechanism is a nylon support, and two nylon supports are fixed on both sides of the U-shaped groove of the bracket.

[0010] Preferably, the rotating fitting is a bushing, which is fixedly fitted onto the end of the disc shaft. The flanges at both ends of the bushing are located outside the two nylon bushings and are fixed by pins on the groove to form a limiting structure.

[0011] Preferably, the aforementioned support mechanism is a bearing box of different sizes, with the bearing on the spool shaft installed inside the bearing box and fixed by a pin on the support groove.

[0012] The technical solution of this utility model has achieved the following beneficial technical effects:

[0013] This invention integrates two or more types of wire-laying frame supports through improvements to the wire reel shaft and bracket. This significantly reduces storage, transportation, and management costs of the wire-laying frames. The lightweight and integrated design also reduces manpower input and lowers construction costs. The integrated wire-laying frame allows for coverage of most working conditions with a small number of types, meeting the needs of diverse construction scenarios. It promotes the standardization and modularization of power construction equipment, reducing the difficulty of storing and managing multiple models of wire-laying frames, and achieving the goal of "cost reduction and efficiency improvement," resulting in significant social and economic benefits. Attached Figure Description

[0014] Figure 1 This is a three-dimensional structural schematic diagram of the present utility model;

[0015] Figure 2 This is a schematic diagram of the structure of an embodiment of the present utility model.

[0016] The reference numerals in the figure are as follows: 1-spool shaft; 2-slot; 3-nylon liner; 4-triangular frame; 5-base frame; 6-adjusting support rod; 7-pin; 8-shaft sleeve. Detailed Implementation

[0017] This utility model is as follows Figure 1 As shown, it includes a tripod 4, a base frame 5, and an adjusting support rod 6. The ends of the tripod 4 and the adjusting support rod 6 are fixed with a support groove 2. The spool shaft 1 is mounted in the support groove 2 via a bearing. The feature is that a support mechanism is installed in the support groove 2. A rotating fitting is mounted outside the bearing of the spool shaft 1. The rotating fitting is placed in the support mechanism and fixed.

[0018] In this embodiment, as Figure 1 As shown, the support mechanism is a nylon support 3, and two nylon supports 3 are fixed on both sides of the U-shaped groove of the support 2.

[0019] In this embodiment, a modification is made based on an 8T cable tray, such as... Figure 1 As shown, a nylon support 3 is installed in the slot 2. The bearing on the 8T wire reel shaft 1 is placed between the two nylon supports 3, with the outer surface of the bearing still in contact with the inner surface of the slot 2. The 8T wire reel shaft 1 is fixed in the nylon support 3 by a pin 7. The 8T wire feeder works normally.

[0020] like Figure 2 As shown, when a 5T pay-off frame is needed, a bushing 8 is installed on the bearing of the 5T wire reel shaft 1, and the bushing 8 is placed inside the nylon support 3. The flanges at both ends of the bushing 8 are located outside the two nylon supports 3. The 5T wire reel shaft 1 together with the bushing 5 is fixed inside the nylon support 3 with a pin 7. Due to the cooperation between the nylon support 3 and the bushing 5, the 5T wire reel shaft 1 can also be smoothly installed in the slot of the 8T pay-off frame. Through the same set of pay-off brackets, not only can the pay-off of the 8T pay-off reel be satisfied, but the pay-off of the 5T pay-off reel can also be satisfied, thus realizing the integration of the pay-off frame.

[0021] For small-sized wire-laying frames, a nylon liner 3 is added inside the slot 2. In another embodiment, for large-tonnage wire-laying frames, bearing boxes of different sizes are added inside the slot 2. Different models of wire reel shafts 1 can also achieve the integration and universality of the wire-laying frame through different bearing boxes. Through the integrated research of serialized wire-laying frames, different wire reel shafts 1 can be interchanged with a single wire-laying frame model, which also meets the needs of diverse construction scenarios and promotes the standardization and modularization of power construction equipment.

[0022] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
