Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power transmission line construction technology, and specifically relates to a wire rope straightening and storage device. Background Technology
[0002] In the process of tension stringing of power transmission lines, steel wire ropes play an irreplaceable role and are often used in various construction conditions such as transition connection, traction, and lifting. A large number of steel wire ropes are used in each project. After the project is completed, when these steel wire ropes are brought back to the equipment company from the site for storage, they are usually quite messy. Furthermore, the steel wire ropes used in construction need to be inspected again before they can be stored.
[0003] Due to lax enforcement of wire rope storage standards and the lack of dedicated storage racks or isolation facilities, haphazard stacking exposes wire ropes to rainwater, mud, and other contaminants, accelerating surface corrosion and internal fiber core aging, reducing tensile strength and abrasion resistance. Furthermore, workers' insufficient awareness of wire rope maintenance leads to a failure to promptly clean surface dirt or inspect for damage after use. Random disposal can result in strand deformation, loosening of the structure, and even concealing existing cracks or broken wires, creating safety hazards.
[0004] The invention disclosed in CN117208677A is an automatic wire rope winding and unwinding device. Its key technical features include a rotating wire-laying frame and a winding mechanism, with a tensioning mechanism, a guiding mechanism, and a winding arrangement mechanism sequentially arranged between them. The rotating frame releases the tension generated during wire rope winding and prevents the rope from becoming increasingly tight during winding. The automatic winding frame, composed of the tensioning mechanism, guiding mechanism, and winding mechanism, uses separate motors to control the winding and unwinding mechanisms, facilitating speed adjustment and smoother coordination. Furthermore, the winding mechanism employs forward and reverse screws for automatic reversal, enabling orderly wire rope winding. This improves the current situation of disorderly wire rope stacking in warehouses of various machinery companies, standardizes the management of power wire ropes, and increases the efficiency of wire rope winding operations.
[0005] However, many problems related to the haphazard stacking and difficulty in transporting wire ropes still need further improvement. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of the existing technology by providing a wire rope organizing and storage device to achieve standardized storage of wire ropes.
[0007] To solve the above technical problems, the technical solution adopted by this utility model is as follows:
[0008] A wire rope straightening and storage device includes a hoisting device, a tension maintaining module and a rope coiling module arranged in sequence. The hoisting device includes a first base frame, a torque release module and a cantilever crane arranged on the first base frame, and the cantilever crane is rotatably arranged on the first base frame.
[0009] The torque release module includes a limiting post fixed on the first base frame, a limiting rope frame rotatably mounted on the first base frame, and a conical frame rotatably sleeved on the limiting post. The bottom of the conical frame is fixed on the limiting rope frame and rotates synchronously with the limiting rope frame.
[0010] During operation, the wire rope is hoisted to the torque release module via the cantilever crane, and then passes through the tension holding module and winds onto the rope coiling module.
[0011] The tension holding module includes a second base frame and a rope entry guide roller, a first pulley group, a second pulley group, and a rope exit guide roller arranged sequentially on the second base frame. The first pulley group and the second pulley group are arranged diagonally opposite each other, and the height of the rope exit guide roller is lower than the height of the rope coil on the rope coiling module.
[0012] The guide roller at the rope outlet end is also equipped with an encoder length measuring device, and the encoder length measuring device is concentrically arranged with the guide roller at the rope outlet end.
[0013] The outer edge of the limiting rope frame protrudes.
[0014] Both the first pulley group and the second pulley group are configured as elastic pulley groups.
[0015] Each of the elastic pulley groups includes a support frame, a guide shaft fixed axially inside the support frame, and a roller frame sleeved on the guide shaft. The roller frame passes through the support frame and has a roller installed at its front end.
[0016] An adjusting nut and a compression spring are also fitted on the guide shaft. The compression spring is located between the adjusting nut and the support frame, and the thrust on the roller frame is changed by rotating the adjusting nut.
[0017] The rope coiling module includes a rope laying device and a rope coil, and both are equipped with independent motors to control the rope laying and coiling speed.
[0018] The motor and the rope reel are connected at the joint via a connecting shaft.
[0019] The guide shaft is fixed to the support frame by a flange.
[0020] The beneficial effects of this utility model are:
[0021] (1) The wire rope straightening and storage device consists of a hoisting device, a tension maintaining module and a rope coiling module arranged in sequence. The hoisting device includes a first base frame and a torque release module and a cantilever crane arranged on the first base frame. The cantilever crane is rotated and arranged on the first base frame. The wire rope can be assisted in positioning by the cantilever crane, which can effectively reduce labor intensity and improve work efficiency. The tension maintaining module applies constant tension to the wire rope through a mechanical structure, making the rope coiling tighter and straighter, and realizing straightening and storage. The rope coiling module frame has a certain slope, which can easily position the rope coil by rolling the rope coil, thus solving the problem of unstable tension of the wire rope during the coiling process.
[0022] (2) To address the problem of heavy wire rope reels being difficult to handle, a hoisting mechanism is used to assist in the transfer and positioning of the wire ropes;
[0023] To address the issues of wire rope accumulation damage and difficulty in coiling, an electric rope coiling device, a wire laying device, and a rope winding device employ a dual-power design, resulting in more orderly and neat wire laying.
[0024] To address the issue of unstable tension in wire ropes during winding, an adjustable tension adjustment module is used. This module employs a combination of rollers and springs in an S-shaped layout to maintain stable tension in the wire rope at all times. This results in a more orderly winding of the wire rope. Furthermore, the tension wheel frame is equipped with an encoder for accurate length measurement of the wire rope.
[0025] The problem of heavy wire rope reels and difficult handling, as well as the problems of wire rope stacking damage and difficulty in winding up, have been solved, and the problem of unstable tension of wire rope during winding up has also been further improved. Attached Figure Description

[0033] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0034] This utility model provides a device for neatly storing steel wire ropes, such as... Figures 1 to 7 As shown.
[0035] A wire rope straightening and storage device includes a hoisting device, a tension maintaining module 3, and a rope coiling module 5 arranged sequentially. The hoisting device includes a first base frame 16, a torque release module 2 and a cantilever crane 1 arranged on the first base frame 16, and the cantilever crane 1 is rotatably arranged on the first base frame 16. The torque release module includes a limiting post 24 fixed on the first base frame 16, a limiting rope frame 25 rotatably mounted on the first base frame 16, and a conical frame 23 rotatably sleeved on the limiting post 24. The bottom of the conical frame 23 is fixed to the limiting rope frame 25 and rotates synchronously with the limiting rope frame 25. In this embodiment, the outer edge of the limiting rope frame 25 protrudes to limit the wire rope.
[0036] During operation, the wire rope 4 is hoisted to the torque release module 2 by the cantilever crane 1, and then passes through the tension holding module 3 and is wound around the rope coiling module 5.
[0037] The tension holding module 3 includes a second base frame 34 and a rope entry guide roller 31, a first pulley group 33, a second pulley group 35 and a rope exit guide roller 36 arranged sequentially on the second base frame 34. The first pulley group 33 and the second pulley group 35 are arranged diagonally opposite each other, and the height of the rope exit guide roller 36 is lower than the height of the rope coil 53 on the rope coiling module 5. Anchor plates 32 are also protruding around the second base frame 34.
[0038] The guide roller 36 at the rope outlet end is also equipped with an encoder length counting device 37, and the encoder length counting device 37 is arranged concentrically with the guide roller 36 at the rope outlet end.
[0039] The first pulley group 33 and the second pulley group 35 are both configured as elastic pulley groups. Each elastic pulley group includes a support frame 333, a guide shaft 334 fixed axially inside the support frame 333, and a roller frame 332 sleeved on the guide shaft 334. The roller frame 332 passes through the support frame 333 and has a roller 331 installed at its front end.
[0040] An adjusting nut 336 and a compression spring 335 are also fitted onto the guide shaft 334. The compression spring 335 is located between the adjusting nut 336 and the support frame 333, and the thrust on the roller frame 332 is changed by rotating the adjusting nut 336. The guide shaft 334 is fixed to the support frame by a flange.
[0041] The rope coiling module 5 includes a wire laying device 57 and a rope reel 53, both equipped with independent motors to control the wire laying and coiling speeds. The rope reel 53 is mounted on a rope reel frame 55, which has corresponding limiting grooves 54. A bearing positioning plate 56 for limiting the position of the rope reel 53 is also provided at its head end. The wire laying device 57 is controlled by a wire laying device motor 51, and the rope reel 53 is controlled by a rope coiling motor 52. The rope coiling motor 52 and the rope reel 53 are connected at their joints via a connecting shaft. When the rope reel rolls to a designated position, it can be connected to the connecting shaft via a connecting shaft buckle plate 4, thereby achieving power transmission.
[0042] The working principle of the wire rope straightening and storage device is as follows:
[0043] The wire rope straightening and storage device uses a cantilever crane 1 to hoist the wire ropes stacked on the ground onto the torque release module 2. The torque release module 2 consists of a conical frame, a limit shaft, and a thrust bearing, and can rotate freely in the circumferential direction to release torque. Then, the wire rope 4 passes through the tension holding module 3. The end roller of the tension holding module 3 is equipped with an encoder length measuring device 37, which can accurately measure the length of the wire rope 4. After passing through the tension holding module, the wire rope is stored by the rope coiling module 5. After the wire rope 4 is stored, the corresponding fastener on the rope coiling module 5 can be opened to allow the wire rope coil to slide down along the frame, which reduces labor intensity.
[0044] The torque release module and the slewing boom are integrated into a frame, making the structure more stable. The torque release module 2 includes a conical frame 23, a limiting post 24, a limiting rope frame 25, and a thrust bearing 27. The torque on the wire rope reel is released by the free rotation of the limiting rope frame 25 driven by the rope coiling module 5. The conical frame 23 and the limiting rope frame 25 are welded together. The top of the frame is designed with a conical structure to make it easier for the wire rope to enter the reel, which can effectively improve the work efficiency. The outer edge of the limiting rope frame 25 is protruding and has a vertical edge that is higher than the ground. A round tube can be welded around the vertical edge to prevent the wire rope 4 from falling off the reel, while also ensuring that the wire rope 4 will not be damaged during the storage operation. A high-load-bearing thrust bearing is installed at the bottom of the frame to ensure that the wire rope 4 will not get stuck when the torque is released, and the reliability is high.
[0045] The two sets of limit pulleys in the tension holding module are arranged diagonally, which forces the wire rope to follow an "S" shape, thus maintaining a certain tension on the wire rope. The pulley system is an elastic pulley system, allowing for flexible manual adjustment. An encoder length measuring device 37, such as a meter counter, is installed concentrically at the guide roller 36 at the rope exit end. Because the height of the rope reel is higher than the guide roller, the wire rope will always be in contact with the guide roller, allowing for accurate measurement of the wire rope length.
[0046] The elastic roller assembly includes rollers 331, roller frame 332, support frame 333, guide shaft 334, compression spring 335, and adjusting nut 336. The roller frame 332 is welded from square tubes, U-shaped plates, and steel plates. A round hole is drilled at the bottom for mating with the guide shaft. The other end of the guide shaft is fixed to the support frame 333 by a flange. The compression spring is installed between the bottom of the roller frame and the adjusting nut. Therefore, under the action of the spring, the roller will always have a forward thrust, and the magnitude of the force can be changed by rotating the adjusting nut.
[0047] The cable winding device 57 and the cable reel 53 of the cable winding module are powered by two different motors, which can better match the cable winding speed and the cable winding speed, making the wire rope storage more orderly. In addition, the slope of the frame is designed according to the diameter of the cable reel, so no additional power is needed when the cable reel is put on or taken off the frame. It can be rolled on or off the frame by relying on the limiting groove. The structure is simple, with low labor intensity and high reliability. After the wire rope reel is rolled into place, it can be positioned by the bearing limiting plate, which can effectively prevent the frame from rolling.
[0048] The motor and the rope reel are connected by a connecting shaft. When the frame rolls to the designated position, the reel and the connecting shaft can be connected by the connecting shaft buckle plate 4 to realize the transmission of power.
