Problems solved by technology
However, the commonly used suspension test benches are mainly designed for air spring suspensions and general suspensions for cars. The former is mainly used for large and medium-sized passenger cars, and the latter is mainly used for small vehicles such as cars. The loading capacity of the above test benches, The measurement range and test space cannot meet the test requirements of large size, heavy load, and complex working conditions for the oil-gas suspension of mining dump trucks. The purpose of effectively testing and testing the performance of oil and gas suspension has become an urgent problem in the industry

The invention discloses a mining self-unloading vehicle oil gas suspension vibration testing stand which is characterized in that: the testing stand comprises an installation pedestal which is provided with guiding columns respectively at four corners of the pedestal, the guiding columns penetrate an lower workbench and an upper workbench, the lower workbench and the upper workbench are sleeved on the guiding columns, tops of the guiding columns are in threaded connection with a fixed top board, a hydraulic exciting oil cylinder is provided between a lower workbench lower end face and the installation pedestal, and connects the former with the latter, a lower clamp and an upper clamp are provided between a lower workbench upper end face and an upper workbench lower end face correspondingly, an upper workbench upper end face is fixedly connected with a crossbeam, two ends of the crossbeam is provided with counterweight blocks respectively, the upper workbench upper end face also is provided with a stay-supported displacement sensor and an acceleration sensor, and the lower workbench upper end face also is provided with an acceleration sensor. Through arranging mining self-unloading vehicle oil gas suspension vibration testing stand in the invention, oil gas suspension performance can be subjected to a test effectively.
Description
technical field [0001] The invention relates to a detection and test device, in particular to a vibration test bench for an oil-gas suspension of a mining dump truck. Background technique [0002] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting, also known as a dump truck. According to different driving modes, it is also divided into 6×4, 8×4 and semi-trailer dump trucks. According to different uses, it is also divided into ① mine dump truck, used to transport coal mines and sand; ② sanitation and green dump truck, used to transport garbage, etc. According to the direction of the compartment turning, there are also front-lift and side-turning dump trucks. [0003] Mining dump truck is a large-scale transport vehicle specially used in mines (coal mine, iron ore, gold mine, etc.), which belongs to one of the mining equipment and is mainly used for the transportation of ore and other bulk materials in mines. Due to changes in dr...
