Description

Technical Field

[0001] This utility model belongs to the technical field of wire rope equipment, and in particular relates to a wire rope winch with adjustable support diameter. Background Technology

[0002] A patent entitled "A Wire Rope Drum" with application number CN202221256240.4 is disclosed in the existing Chinese patent database. This patent aims to solve the problem that the entire wire rope drum needs to be replaced after wear, which is not conducive to cost savings. It includes a first end plate, a second end plate, and a drum body. The drum body is sandwiched between the first end plate and the second end plate. The drum body includes an inner drum and an outer drum. One side of the inner drum is fixedly connected to the first end plate. The outer drum is sleeved on the inner drum. A screw rod is passed through the side of the outer drum and the inner drum near the first end plate. A nut is provided on the screw rod. The second end plate is sleeved on the outer drum and is snapped into the outer drum. A support is provided on the side of the second end plate away from the snap-in point. A limiting rod is rotatably connected to the support. The outer drum and the inner drum are provided with relief grooves that match the limiting rod. A locking device for fixing the limiting rod is provided on the second end plate. The inner cylinder is fixedly connected to the first end plate, and one side of the outer cylinder is connected to one side of the inner cylinder by a screw. The cooperation between the limiting rod and the clearance groove facilitates the disassembly and assembly of the outer cylinder with the first end plate, the inner cylinder and the second end plate.

[0003] In the existing technology, there are many diameter specifications for wire ropes. During the wire rope winding process, the winding diameter needs to be adjusted according to the specifications of the wire rope to ensure the tightness of the wound wire rope and avoid excessive stress and premature fatigue damage caused by excessive bending. Therefore, this paper aims to propose a wire rope winch with adjustable support diameter, which can adjust the winding diameter according to the specifications of the wire rope, thereby improving the winding effect of the wire rope. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to adjust the winding diameter of the wire rope during the winding process. In order to solve the above technical problem, this utility model provides a wire rope winch with adjustable support diameter.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A wire rope winch with adjustable support diameter includes a base, a counterweight integrally formed on one side of the base, a horizontally arranged central rod fixedly connected to the counterweight, a winch body fixedly sleeved on the central rod, a sleeve horizontally slidably sleeved on the free end of the central rod, a plurality of first hinge plates integrally formed on the outer circumferential surface of the sleeve, the plurality of first hinge plates being radially evenly distributed with the axis of the central rod as the center line, the winch body having a number of through slots corresponding to the number of first hinge plates, the length direction of the through slots being along the diameter direction of the winch body, a second hinge plate located in the same plane as the corresponding first hinge plate being inserted into the through slot, the second hinge plate being connected to the corresponding first hinge plate via a set of parallel connecting rods.

[0007] Compared with the prior art, the beneficial effects of this utility model are: due to the cooperative arrangement of the sleeve, the first hinge plate and the second hinge plate, the winding diameter formed by several hinge plates can be adjusted by changing the lateral position of the sleeve on the central rod, so as to avoid excessive bending of the wire rope caused by the winding diameter being too small, thereby generating excessive stress and premature fatigue damage. This device is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, the outer circumferential surface of the free end of the central rod is provided with several grooves of various shapes. The grooves are radially distributed with the axis of the central rod as the center line, and the length direction of the grooves is consistent with the length direction of the central rod. The inner wall of the sleeve is integrally provided with a locking protrusion that slides and engages with the grooves.

[0009] As a preferred embodiment, the free end of the central rod is provided with an external thread, and a stop block is screwed onto the free end of the central rod located outside the sleeve, with the inner end face of the stop block abutting against the outer end face of the sleeve.

[0010] As a preferred embodiment, rollers are provided on the second hinge plates located on both sides of the through groove. The outer circumferential surface of the rollers is fitted to the surface of the winch body to assist the movement of the second hinge plates within the through groove.

[0011] As a preferred embodiment, the first hinge plate and the second hinge plate are provided with at least three sets. Attached Figure Description

[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 As shown, a wire rope winch with adjustable support diameter includes a base 1, a counterweight 2 integrally formed on one side of the base 1, a horizontally arranged central rod 3 fixedly connected to the counterweight 2, a winch body 4 fixedly sleeved on the central rod 3, a sleeve 5 horizontally slidably sleeved on the free end of the central rod 3, a plurality of first hinge plates 6 integrally formed on the outer circumference of the sleeve 5, the plurality of first hinge plates 6 being radially evenly distributed with the axis of the central rod 3 as the center line, the winch body 4 having a number of through slots 7 corresponding to the number of first hinge plates 6, the length direction of the through slots 7 being along the diameter direction of the winch body 4, a second hinge plate 8 located in the same plane as the corresponding first hinge plate 6 being inserted in the through slots 7, the second hinge plate 8 being connected to the corresponding first hinge plate 6 via a set of parallel connecting rods 9, the two ends of the connecting rods 9 being hinged to the first hinge plate 6 and the second hinge plate 8 respectively.

[0017] like Figure 2 As shown, several grooves 10 of various shapes are formed on the outer circumferential surface of the free end of the central rod 3. These grooves 10 are radially distributed around the axis of the central rod 3, and their length direction is consistent with that of the central rod 3. A locking protrusion 11 is integrally formed on the inner wall of the sleeve 5 to slide and engage with the grooves 10. The free end of the central rod 3 is provided with an external thread 12. A stop block 13 is screwed onto the free end of the central rod 3 located outside the sleeve 5, and the inner end face of the stop block 13 abuts against the outer end face of the sleeve 5. The inner bottom surface of the grooves 10 is recessed into the root surface of the external thread 12.

[0018] Specifically, rollers 14 are provided on the second hinge plates 8 located on both sides of the through groove 7. The outer circumferential surface of the rollers 14 is fitted against the surface of the winch body 4 to assist the movement of the second hinge plates 8 within the through groove 7. By integrally providing shafts on both sides of the second hinge plates 8, the rollers 14 are rotatably connected to the shafts and fitted against the surface of the winch body 4, ensuring that the second hinge plates 8 can move smoothly along the length direction of the through groove 7, i.e., the diameter direction of the winch body 4, during the lateral movement of the sleeve 5, thereby changing the winding diameter.

[0019] Specifically, at least three sets of the first hinge plate 6 and the second hinge plate 8 are provided. The arrangement of three or more sets improves the stability of the winding frame formed by several second hinge plates 8. At the same time, in order to avoid wear of the wire rope during the winding process, soft pads can be provided on the outer surface of the second hinge plate 8 by means of bonding, wrapping or other methods, so as to protect the wire rope from hard friction with the second hinge plate 8.

[0020] When this utility model is in operation, the operator moves the sleeve 5 laterally along the axis of the central rod 3. When the sleeve 5 moves inward, the connecting rod 9 swings clockwise, and at the same time, the second hinge plate 8 moves towards the outer circumference of the winch body 4 along the direction of the through groove 7. The winding diameter formed by the several second hinge plates 8 increases, which can accommodate steel wire ropes with larger diameters. Then, the stop block 13 is screwed onto the free end of the central rod 3 and set against the outer end face of the sleeve 5. Because when the steel wire rope is wound on the frame formed by the second hinge plates 8, due to the gravity of the steel wire rope, there is a tendency to squeeze the sleeve 5 outward along the direction of the central rod 3. Therefore, the stop block 13 is placed against the outer end face of the sleeve 5 to restrict the sleeve 5 from moving laterally outward.

[0021] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
