Embodiment 1

[0027] The embodiment of the present invention provides a kind of winch test device, see figure 1 , the device comprises: a base plate 2 for installing the winch 1 to be tested, a first cable 3 for being connected to the winch 1 to be tested, a loading winch 4, a second cable 5 connected to the loading winch 4, and a shackle 6 , the force measuring device 7 for measuring the tension that the second cable 5 is subjected to, the loading winch control system 8 for controlling the loading winch 4 and the winch control system 9 for controlling the winch 1 to be tested; the first cable 3 passes The shackle 6 is connected to the second cable 5 . The loading winch 4 is electrically connected to the loading winch control system 8 , and the test winch 1 is electrically connected to the test winch control system 9 .

[0028] Among them, various performance parameters of the loading winch 4 have been calibrated, and the load capacity can be 125 tons to 500 tons.

[0029] Preferably, the...

Embodiment 2

[0037] The embodiment of the present invention provides a kind of winch test method, this method comprises:

[0038] Set the loading winch to the cable receiving state, and adjust the output of the loading winch through the loading winch control system, so that the tension on the second cable corresponds to the different load values ​​of the winch to be tested, and carry out load and overload tests on the winch to be tested. This test method uses the loading winch as the external load, and completes the load and overload tests without replacement.

[0039] Wherein, the drum of the winch to be tested is wound with a specified number of layers of the first cable, and its end passes through the fairlead and is firmly connected with the second cable on the loading winch through a shackle.

[0040] In specific implementation, the above-mentioned different load values ​​can be selected according to the test requirements and actual conditions, for example: during the load test: the t...

Abstract

The invention discloses a testing device and a method of a winch, belonging to the winch manufacturing field. The device comprises a bottom plate for installing a to-be-tested winch, a first cable connected with the to-be-tested winch, a loading winch, a second cable connected with the loading winch, a shackle, a force-measuring device for measuring tensile force of the second cable, a loading winch control system for controlling the loading winch and a to-be-tested winch control system for controlling the to-be-tested winch; wherein the first cable is connected with the second cable by the shackle. The device takes the loading winch as external load, only needs to regulate the output of the loading winch to change external load and then finish loading test of the to-be-tested winch; therefore, the device avoids complex work caused by frequently changing the external load when performing load testing.

Description

technical field [0001] The invention relates to the field of winch manufacture, in particular to a winch test device and method. Background technique [0002] A winch, also known as a hoist, is a lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. In order to ensure the safety of subsequent operations, strict performance tests are required during the winch manufacturing process, mainly including: load test, overload test, emergency stop test and emergency release test, etc. [0003] The existing winch test device mainly includes structures such as a tower frame, a pulley block arranged on the top of the tower, an external load, and a wire rope. One end of the wire rope is fixed on the external load, and the other end is connected to the winch to be tested by going around the pulley block, and the performance of the winch to be tested is checked by lifting or lowering the external load. When carrying out different performance tests, i...
