Tension tester for super tonnage winch

Abstract

The invention relates to a tension tester for a super tonnage winch. The tension tester comprises a support I, a support II, a coiling block and a testing steel rope wound around the coiling block. The support I and the support II are fixedly arranged on a foundation. The coiling block is erected between the support I and the support II. A free end of the testing steel rope is connected with one testing end of a plate ring type tension sensor. Another testing end of the plate ring type tension sensor is connected with a steel rope of the winch to be tested. Levers are arranged at the back ends of the support I and the support II. One ends of the levers are connected with a braking belt of the coiling block. The other ends of the levers are provided with scale pans in a hanging mode. The scale pans are used for pulling the braking belt to stop the coiling block, and weights are placed on the scale pans. An extending end of a rotating shaft of the coiling block is connected with a power output shaft of a speed reducer. The power output shaft of the speed reducer is provided with a power input device for adding force to the coiling block. According to the tension tester, testing efficiency is high, and tested data are accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of tensile testing, and in particular relates to a tensile testing machine for a super-large-tonnage winch. Background technique [0002] The traditional hoist tension test uses a test bench, and the weight is pulled by turning the pulley, which has potential safety hazards for the large-tonnage hoist tension test. Moreover, when the tension is too large, it cannot be achieved only through the test bench. During the last test, the efficiency of the pulley was lost, and the accuracy of the actual pulling force of the hoist could not be guaranteed. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a tensile testing machine for a super-large-tonnage hoist. The device greatly improves the reliability and accuracy of the tensile test of the super-large-tonnage hoist. [0004] In order to achieve the above object, the technical scheme that ...
