Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hoisting and capstan equipment and relates to a loose rope protection device for hoisting and capstan equipment. Background Art
[0002] At present, winches and other common hoisting equipment are mostly used in underground operations to send objects or personnel into or out of the well. During use, the wire rope of the winch may become loose, causing the force on the wire rope to change, affecting the normal transportation of objects. At this time, if the winch continues to run, it will cause the bending of the middle part of the wire rope to become more serious. If the wire rope suddenly recovers at this time, it will cause the transported hot objects or personnel to fall rapidly, causing a safety accident and damaging the winch. Therefore, it is necessary to monitor the wire rope of the hoisting equipment in real time. When loose rope occurs, the hoisting equipment should be stopped in time, and the operation should be resumed after troubleshooting. The current existing hoisting equipment protection device has low detection accuracy for loose rope conditions, and often cannot detect loose ropes in a timely and accurate manner, resulting in poor use effect. Utility Model Content
[0003] The purpose of the utility model is to provide a loose rope protection device for a hoisting equipment to solve the problem that the existing loose rope protection device in the background technology cannot accurately detect the loose rope part.
[0004] To this end, the utility model adopts the following technical solutions:
[0005] A loose rope protection device for a hoisting equipment includes a winch, the winch includes a machine body and a steel wire rope, a fixed pulley is provided on one side of the machine body, the steel wire rope is wound on the fixed pulley, a base is provided between the machine body and the fixed pulley, a support plate is provided on the base, the support plate can move up and down in a vertical direction, a first support rod is provided at one end of the support plate in the length direction, and a second support rod is provided at the other end, the first support rod is connected to a detection rope, the detection rope is below the steel wire rope, the detection rope is connected to a tension sensor, the tension sensor is connected to the second support rod, the tension sensor is connected to a controller, and the controller is connected to the machine body.
[0006] Furthermore, an adjusting sleeve is provided on the first support rod, the detection rope passes through the adjusting sleeve, a screw hole is provided on the side wall of the sleeve, and a screw is provided in the screw hole.
[0007] Furthermore, the first support rod and the second support rod are arranged vertically.

[0009] Furthermore, a hydraulic cylinder is provided on the base, and the support plate is fixed to the top end of the hydraulic cylinder.
[0010] Furthermore, the hydraulic cylinder is arranged vertically.
[0011] The beneficial effects of the present invention are as follows: a detection rope is arranged below the steel wire rope. When the steel wire rope becomes loose, the steel wire rope is subjected to force conveniently, causing the middle part of the steel wire rope to sag and contact the detection rope and exert downward pressure on the detection rope, and then the loose rope is detected by the tension sensor, and the detection result is timely and accurate; the structure is simple, the manufacturing cost is low, and the use method is convenient.

DETAILED DESCRIPTION
[0017] The utility model is described in detail below with reference to the accompanying drawings:
[0018] like Figure 1-3As shown, a rope slack protection device for a winch includes a winch 1, which is an existing conventional winch. The winch 1 includes a body 101 and a wire rope 102. The body 101 can roll up or release the wire rope 102, and lift or lower an object through the wire rope 102. A fixed pulley 2 is provided on one side of the body 101. The fixed pulley 2 is located at the same height as the body 101, and the wire rope 102 is wound around the fixed pulley 2, so that the fixed pulley 2 and the body 101 are aligned. The steel wire rope 102 between the fixed pulley 2 and the machine body 101 is in a horizontal state. When the rope is loose, the force on the steel wire rope 102 changes, causing the middle part of the steel wire rope 102 between the fixed pulley 2 and the machine body 101 to sag and be in an arc state. A base 3 is provided between the machine body 101 and the fixed pulley 2. A support plate 4 is provided on the base 3. The support plate 4 can move up and down in the vertical direction. Specifically, a vertically arranged hydraulic cylinder 5 is provided on the base 3. The middle part of the support plate 4 is fixed to the top of the hydraulic cylinder 5. , the support plate 4 can be driven to move downward by the hydraulic cylinder 5. A first support rod 6 is provided at one end of the support plate 4 in the length direction and a second support rod 7 is provided at the other end. The first support rod 6 and the second support rod 7 are arranged vertically. The first support rod 6 is connected to a detection rope 8, and the detection rope 8 is connected to a tension sensor 9. The tension sensor 9 is connected to the second support rod 7. The detection rope 8 is located below the wire rope 102. The detection rope 8 is arranged horizontally and is perpendicular to the wire rope 102. When the wire rope 102 is loose and sags, the wire rope 102 contacts the detection rope 8 and applies external force to the detection rope 8, thereby causing the sensor 9 to detect a change in the tension of the detection rope 8, thereby quickly judging that a loose rope has occurred. The tension sensor 9 is connected to a controller 10, and the controller 10 is connected to the machine body 101. The tension sensor 9 can transmit a tension signal to the controller 10, and the controller 10 can control the machine body 101 to stop running.
[0019] In order to prevent the detection rope 8 from becoming loose after being used for a period of time and affecting the detection results, an adjusting sleeve 11 is provided on the first support rod. The detection rope 8 passes through the adjusting sleeve 11. The side wall of the adjusting sleeve 11 is provided with a screw hole 12. A screw 13 is provided in the screw hole 12. The inner end of the screw 13 rests on the detection rope 8. When the detection rope 8 is loose, the screw 13 can be loosened, and then the detection rope 8 can be straightened, and then the screw 13 can be tightened to complete the adjustment of the detection rope 8.
[0020] The usage of this utility model is as follows:
[0021] First, install the base 3 and the detection rope 8. After the installation is completed, the distance between the detection rope 8 and the wire rope 102 can be adjusted by the hydraulic cylinder 5 so that the distance between the detection rope 8 and the wire rope 102 is constant. If the distance between the detection rope 8 and the wire rope 102 is too far, it will easily affect the detection result. When the winch 1 is operating normally, the wire rope 102 above the detection rope 8 is in a taut state and will not contact the detection rope 8. When the wire rope 102 of the winch 1 is loose, the force on the wire rope 102 is reduced. When the wire rope 102 above the detection rope 8 is loose and droops, the wire rope 102 contacts the detection rope 8 and applies downward pressure to the detection rope 8, thereby changing the tension value detected by the tension sensor 9, and then detecting the loose rope. At this time, the controller 10 controls the body 101 to stop to prevent installation accidents.
