A hydraulic cylinder anti-lateral force performance test device

Abstract

The invention provides a device for testing the lateral force resisting performance of a hydraulic cylinder. According to the device, a mounting base is horizontally placed and fixed; a mounting bracket is fixed at one side of the mounting base and used for supporting and fixing a to-be-tested hydraulic cylinder; a loading actuator is fixed at the other side of the mounting base; a load sensor isconnected at the tail end of a piston rod of the loading actuator; a rotating wheel bracket is connected at the end, which faces away from the piston rod of the loading actuator, of the load sensor; aloading rotating wheel is fixed on the rotating wheel bracket through a rotating shaft of the loading rotating wheel; and the loading rotating wheel is propped against the piston rod of the to-be-tested hydraulic cylinder. The device has the beneficial effects that a lateral force is loaded on the hydraulic cylinder and the degree of freedom in the axial direction, of the piston rod of the to-be-tested hydraulic cylinder is released by means of a rotating wheel way, so that the testing of the lateral force bearing performance of the hydraulic cylinder in full stroke at any position is realized.

Description

technical field [0001] The invention relates to a hydraulic cylinder lateral force performance testing device, which belongs to the field of hydraulic cylinder testing. Background technique [0002] The hydraulic cylinder is the actuator in the hydraulic transmission system, which can convert hydraulic energy into mechanical energy. It is often used in dynamic loading or static loading in the industrial field or test field. In the working conditions of the hydraulic cylinder, some working conditions require the hydraulic cylinder to bear a large lateral force or overturning moment, which requires the hydraulic cylinder to have strong lateral force resistance. [0003] At present, the lateral force resistance performance of the existing hydraulic cylinders is only estimated by theoretical calculations without actual measurement, and there is no mature lateral force measurement device on the market. It will cause certain danger. Once the theoretical calculation value is wron...

[0003] At present, the lateral force resistance performance of the existing hydraulic cylinders is only estimated by theoretical calculations without actual measurement, and there is no mature lateral force measurement device on the market. will pose a certain risk

Once the theoretical calculation value is wrong, the estimated value is larger than the actual tolerable lateral force, and the load is carried out according to the estimated value during use, the lateral force may be higher than the actual tolerable lateral force. Lead to loading failure and damage to the hydraulic cylinder, and more serious may cause dangerous accidents to the operator
