Hydraulic load test system for crawler type walking device

Abstract

The invention discloses a hydraulic load test system for a crawler type walking device. The hydraulic load test system for the crawler type walking device comprises a main control unit, an oil supplementary unit, a tensioning unit, a cooling unit and an external oil tank, wherein the main control unit is connected with the oil supplementary unit through an oil pipe; and the oil supplementary unit,the tensioning unit and the cooling unit are connected with the external oil tank through oil pipes. A proportional overflow valve in a loop is selected to control the pressure and the oil pump displacement difference of a driver load motor, and the displacement and the pressure of crawler tensioning are adjusted through the tensioning unit, so that the aims of reducing the equipment installationperiod, reducing the manufacturing cost, and improving the experiment control accuracy and the system universality are achieved.

Description

technical field [0001] The invention relates to a walking structure detection device, in particular to a hydraulic loading test system for a crawler-type walking device. Background technique [0002] The detection device of the walking structure in the prior art is mainly composed of a hydraulic motor, a traveling reducer, a coupling, a speed increaser, a dynamometer, etc. The input end of the walking reducer is connected to the driving hydraulic motor, and the output end is passed through the speed increaser. , The dynamometer is connected, and the loading test is simulated. Use the test platform, eddy current dynamometer, speed reducer and coupling, etc., to connect with the travel reducer and simulate the resistance loading. Through the test platform, you can complete the performance tests of different types of travel reducer loading, fatigue strength, transmission efficiency, etc. , to provide test and test data parameters for the selection of the walking reducer; howev...

Problems solved by technology

Use the test platform, eddy current dynamometer, speed reducer and coupling, etc., to connect with the travel reducer and simulate the resistance loading. Through the test platform, you can complete the performance tests of different types of travel reducer loading, fatigue strength, transmission efficiency, etc. , to provide test and test data parameters for the selection of the walking reducer; however, the equipment investment is large, and the test bench includes dynamometers, speed increasers, couplings and other transmission components, test platforms and other consoles, and the price and cost are high; The axial connection is long, takes up a lot of space, and has poor versatility. In particular, the crawler type travel device currently installs the travel reducer directly on the construction machinery for inspection and testing. This method has a long test cycle, a large operating site, and high test costs. Part of the power is large, the energy consumption is large, and the energy cannot be recovered
