Tension test bench for electric winch

Abstract

A tension test bench for an electric winch comprises a buffer hydraulic oil cylinder, a tension sensor, a force measuring oil cylinder, a bench frame, a plurality of fixed steel wire ropes and a pulley, a tested electric winch is installed on one side of the rack, and one end of a first fixed steel wire rope is installed on a winding drum of the electric winch. One ends of the second fixed steel wire rope and the third fixed steel wire rope are mounted on the other side of the bench frame; the other ends of the second fixed steel wire rope and the third fixed steel wire rope are respectively connected with the tension sensor and one end of the force measuring oil cylinder; a connecting frame and a pulley are respectively mounted at two side ends of the buffer hydraulic oil cylinder; the other end of the first fixed steel wire rope is positioned in a pulley groove in one side of the buffer hydraulic cylinder; the tension sensor, the other end of the force measuring oil cylinder and thehead and tail ends of the fourth fixed steel wire rope are connected together; the middle of the fourth steel wire rope is located in a groove of the pulley on the other side of the buffering hydraulic cylinder. The tension test bench is more convenient to disassemble and assemble, convenience is brought to operators, and measured tension data is more real and effective.

Description

technical field [0001] The invention relates to the technical field of electric winch tensile test equipment, in particular to an electric winch tensile test bench. Background technique [0002] The electric winch is a kind of machinery widely used in industry and other fields. The pulling performance of the electric winch is directly related to the working performance and safety of the application equipment (such as the electric winch used by the crane, if the pulling force is not good and the performance is poor, there will be It may be impossible to lift heavy objects normally due to excessive load, and even cause safety accidents), so it is particularly important to test the tensile performance of the electric winch before application. [0003] At present, there is no special test bench for the tensile test of the electric winch. Generally, one end of the wire rope is temporarily fixed, and the other end is fixedly connected to the reel of the electric winch. Then the el...

Problems solved by technology

[0004] In order to overcome the existing pull test for electric winches, because there is no special test bench, too many connection points before and after the test will bring great inconvenience to the test personnel, which may cause the pull sensor to be overstressed instantaneously. Large disadvantages that affect the measurement accuracy or even the probability of damage, and only relying on a tension sensor to display the tension data of the electric winch can not guarantee that the tested electric winch tension data is true and effective, which will affect the safety of the electric winch. The drawbacks of the present invention After fixing the electric winch before the test, it only needs to connect the steel wire rope and the reel of the electric winch, which is more convenient for disassembly and assembly, which brings convenience to the operator, and uses the buffer cylinder as the tension sensor and force measuring cylinder. The buffer device prevents the possibility that the tension sensor and the force measuring cylinder are temporarily overstressed and the measurement accuracy is affected or even damaged, and the tension sensor and the force measuring cylinder are used to simultaneously display the tested tension data, making the measured tension data more real and effective. The electric winch tensile test bench provides strong technical support for the safety application of electric winch
