Description

Technical Field

[0001] This utility model relates to the field of wire rope pipe winding machines, and in particular to a wire rope pipe winding machine with a pre-tightening function. Background Technology

[0002] As an important load-bearing and traction material, steel wire rope is widely used in construction, bridges, hoisting and other fields. Its quality directly affects the safety of the project. In the production process of steel wire rope, the tube stranding machine is the key equipment to realize the stranding of multiple steel wires. The single wires and strands need to be stranded by the stranding machine before they can be made into finished cables. Stranding is achieved by the single wires rotating around the stranding axis at a constant angular velocity and the strands moving forward at a constant speed. The commonly used materials are copper and aluminum. Copper and aluminum wires can be stranded into various specifications and types of cables. The tube stranding machine is a machine that uses the rotation of a tubular rotating body to complete the stranding process to produce stranded wires. The baskets of each pay-off reel are floatingly installed on the axis of the tube body and then wound on the round rollers for collection.

[0003] Existing wire rope tube stranding machines guide the wire to the winding roller via two guide rollers after stranding for winding. However, existing wire rope tube stranding machines rely solely on the friction of the traction rollers and lack a wire rope pre-tensioning adjustment function. This results in uneven tension among the strands of the wire rope, which can easily lead to problems such as uneven tension, wire breakage, or loose stranding. Consequently, the quality of the stranded wire rope is affected, and the service life and reliability of the wire rope are reduced. Therefore, a wire rope tube stranding machine with a pre-tensioning function is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a wire rope pipe winch with a pre-tensioning function, which aims to improve the problem in the prior art that "the wire rope pipe winch equipment relies solely on the friction of the traction roller, resulting in uneven tension of each strand of the wire rope".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wire rope conduit winch with pre-tensioning function, comprising a frame and a base, wherein a tensioning plate is provided inside the frame, a guiding mechanism is provided inside the frame, and a pre-tensioning mechanism is provided inside the frame, the pre-tensioning mechanism comprising a square frame and a screw, wherein a groove is provided inside the tensioning plate, the square frame is slidably connected to the inner wall of the groove, an I-beam wheel is rotatably connected to the inner wall of the square frame, the screw is threadedly connected to the inner wall of the tensioning plate, the screw is rotatably connected to the surface of the square frame, a knob is fixedly connected to the end of the screw away from the square frame, and a rope outlet tube is fixedly connected to the right side of the inner wall of the frame, wherein a wire rope is provided inside the rope outlet tube.

[0012] As a further description of the above technical solution:

[0013] The guiding mechanism also includes a take-up frame, which is fixedly connected to the outer wall of the support tube. A hollow tube is fixedly connected to the inner wall of the take-up frame, and the wire rope passes through the interior of the hollow tube.

[0021] 1. In this utility model, by setting a guiding mechanism, the wire rope maintains a constant tension through the position locking of the I-beam pulley during the winding process. The fixed pulley, hollow tube and collar of the guiding mechanism ensure that the wire rope is smoothly transported along the central axis, avoiding problems such as loose winding and breakage caused by uneven tension or deviation in direction.

[0022] 2. In this utility model, the screw is driven to rotate by the knob, and the screw drives the square frame to slide linearly along the radial direction of the tensioning plate in the groove of the tensioning plate through the thread transmission, thereby adjusting the position of the I-beam wheel. If it is necessary to increase the preload, the knob is rotated to make the square frame drive the I-beam wheel to move closer to the center of the tensioning plate to tighten the wire rope. If it is necessary to reduce the preload, the knob is rotated in the opposite direction to loosen the wire rope until a suitable tension is achieved, which meets the high-efficiency stranding requirements of multiple specifications of wire rope and improves applicability.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3This utility model provides an embodiment of a wire rope conduit winch with pre-tensioning function, comprising a frame 1 and a base 2. The frame 1 is located on the left side of the base 2. The frame 1 and the base 2 serve as the basic support structure of the equipment, providing a mounting carrier for internal components such as the tension plate 3, the guide mechanism 10, and the pre-tensioning mechanism 11, ensuring the stability of the overall structure. The tension plate 3 is provided inside the frame 1, providing a guide track for the horizontal movement of the frame 111, and supporting the screw 114 to achieve pre-tensioning force adjustment. The guide mechanism 10 is provided inside the frame 1, and the pre-tensioning mechanism 11 is provided inside the frame 1. The pre-tensioning mechanism 11 includes a frame 111 and a screw 114. The tension plate 3 has a groove 112 inside, and the frame 111 is slidably connected to the inner wall of the groove 112. The sliding direction of the frame 111 is the radial direction of the tension plate 3.

[0031] Reference Figure 3 , Figure 4 A helical wheel 113 is rotatably connected to the inner wall of the frame 111. The sliding of the frame 111 causes the helical wheel 113 to move, changing the tensioning path of the wire rope 19. The surface of the wire rope 19 contacts the surface of the helical wheel 113. The helical wheel 113 moves with the frame 111, realizing the tensioning or slack adjustment of the wire rope 19. The screw 114 is threadedly connected to the inner wall of the tensioning plate 3. The screw 114 is rotatably connected to the surface of the frame 111. A knob 115 is fixedly connected to the end of the screw 114 away from the frame 111. Rotating the knob 115 can drive the screw 114 to rotate, causing the frame 111 to move linearly along the groove 112, precisely adjusting the position of the helical wheel 113, thereby applying or releasing the preload of the wire rope 19. A rope outlet tube 18 is fixedly connected to the right side of the inner wall of the frame 1. The wire rope 19 is installed inside the rope outlet tube 18.

[0032] Reference Figures 2-4 The guiding mechanism 10 includes a horizontally arranged support tube 101, which is fixedly connected to the right side of the inner wall of the frame 1. The surface of the support tube 101 is fixedly connected to the inner wall of the tensioning plate 3. The guiding mechanism 10 also includes a circular plate 102, which is fixedly connected to the outer wall of the support tube 101. A fixed pulley 103 is rotatably connected to the inner wall of the circular plate 102. The fixed pulley 103 on the inner wall of the circular plate 102 can rotate, change the direction of the wire rope 19 and reduce friction, guide the wire rope 19 to turn, and ensure its smooth delivery. The surface of the fixed pulley 103 contacts the surface of the wire rope 19.

[0033] Reference Figures 2-4The guiding mechanism 10 also includes a take-up frame 104, which is fixedly connected to the outer wall of the support tube 101. A hollow tube 105 is fixedly connected to the inner wall of the take-up frame 104. The wire rope 19 passes through the interior of the hollow tube 105. The hollow tube 105 guides and constrains the wire rope 19 in a straight line to prevent it from deviating during transport. The guiding mechanism 10 also includes a collar 106, which is fixedly connected to the left side of the inner wall of the frame 1. The wire rope 19 passes through the interior of the collar 106. The central axes of the tension plate 3, the circular plate 102, and the take-up frame 104 are all on the same straight line. The collar 106 is fixed to the left inner wall of the frame 1. The wire rope 19 passes through the collar 106, further defining the initial direction of the wire rope 19 and ensuring that its axis is consistent with the central axis of the tension plate 3, the circular plate 102, and the take-up frame 104, thus ensuring uniform tension.

[0034] Working principle: In use, according to the specifications and stranding requirements of the wire rope 19, rotate the knob 115 of the pretensioning mechanism 11. The knob 115 drives the screw 114 to rotate. The screw 114 drives the square frame 111 to slide linearly along the radial direction of the tensioning plate 3 in the groove 112 of the tensioning plate 3 through the thread transmission, thereby adjusting the position of the I-beam wheel 113. If it is necessary to increase the pretension force, rotate the knob 115 to make the square frame 111 drive the I-beam wheel 113 to move closer to the center of the tensioning plate 3 to tighten the wire rope 19. If it is necessary to reduce the pretension force, rotate the knob 115 in the opposite direction to loosen the wire rope 19 until the appropriate tension is achieved.

[0035] Subsequently, the wire rope 19 is guided in a straight line through the hollow tube 105 of the take-up frame 104 to the fixed pulley 103 of the circular plate 102. The fixed pulley 103 changes the direction of the wire rope 19 and guides it to bypass the hollow tube 105. Then, through the positioning of the support tube 101 and the tensioning plate 3, it finally passes through the collar 106 from the left side inside the frame 1 and is output to the winding component of the winch. When the tube winch is started, during the winding process, the pre-tensioning mechanism 11 maintains a constant tension force by locking the position of the I-beam pulley 113. The fixed pulley 103, hollow tube 105 and collar 106 of the guiding mechanism 10 ensure that the wire rope 19 is smoothly transported along the central axis, avoiding problems such as loosening and breakage caused by uneven tension or deviation in direction, thereby achieving efficient and stable pre-tensioning and winding of the wire rope 19.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
