Abstract
Description
Technical Field
[0001] The utility model relates to a device for detecting the tightness of a steel wire rope of a winch hoist. Background Art
[0002] When the winch hoist is closing the gate, often due to various reasons, the movable pulley will drop too much out of control after the gate is closed, and finally the wire rope will be too loose. In this way, the wire rope will not run according to the preset parameters when the gate is opened next time, resulting in inaccurate data transmitted by the winch hoist control system. In serious cases, the door will be mechanically closed when it is opened. Therefore, the existing winch hoist has limitations and needs to be improved. Summary of the invention
[0003] The purpose of the utility model is to design a device for detecting the tightness of a wire rope of a winch hoist.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a wire rope tension detection device for a winch hoist, comprising: a thin nut 1, a sensor 2, a support 3, a sensor support 4, a compression spring 5, a sensing sheet 6, a pulley support 7, a positioning pulley 8, a wire rope 9, an anti-slip pulley 10 and a balancing pulley support 11. Its characteristics are: the compression spring 5 is passed through the screw 701 of the pulley support 7, the screw 701 of the pulley support 7 is passed through the positioning hole of the support 3, one end of the compression spring 5 is attached to the pulley support 7, and the other end is attached to the support 3, two thin nuts 1 are mutually locked and fixed on the screw 701 of the pulley support 7 along the axial direction, the pulley support 7 is positioned on the support 3 and has a certain range of movement along the axial direction of the screw 701, but will not fall off by itself, the sensor 2 is fixed on the sensor support 4, the sensor support 4 is fixed to the support 3 with screws, and the sensing sheet 6 is fixed on the support 3 with screws. On the pulley bracket 7, the positioning pulley 8 and the anti-slip pulley 10 are positioned on the pulley bracket 7, and the wire rope 9 is passed between the positioning pulley 8 and the anti-slip pulley 10. When the wire rope 9 is tightened, the wire rope 9 will push the pulley bracket 7 to compress the compression spring 5, so that the two mutually locked thin nuts 1 are at a certain distance from the support 3, and the induction sheet 6 senses the sensor 2, and the sensor 2 transmits a tensioning signal. When the wire rope 9 is loose, the energy stored in the compression spring 5 when it is compressed is released, so that the induction sheet 6 is out of the sensing range of the sensor 2, and the sensor 2 cannot transmit a tensioning signal.

When the wire rope 9 is loose, the energy stored in the compression spring 5 when it is compressed is released, so that the induction sheet 6 is out of the sensing range of the sensor 2. The sensor 2 cannot transmit a tension signal, indicating that the wire rope is loose and not tensioned, and cannot work normally. A wire rope tension detection device for a winch gate hoist has a reasonable design, a compact structure, and is easy to operate.
