Problems solved by technology
[0003] However, the existing hydraulic press can only squeeze in one direction, and it is difficult to simulate the extrusion of the real road vehicle on the telescopic device, and the hydraulic machine can only detect the front side of the telescopic device, and it is difficult to detect the side and slope of the telescopic device, because the telescopic After the device is installed, it also needs to bear the tension and vibration of the wall, so it is difficult for the existing hydraulic machine to detect the strength of these aspects

The invention relates to the technical field of bridge telescopic device testing, in particular to a deformation bearing performance comprehensive test bed suitable for a highway bridge telescopic device, which comprises a hydraulic machine, a lubricating structure is mounted on the hydraulic machine, a cleaning structure is mounted on the lubricating structure, and the hydraulic machine is connected with an adjusting structure. A fixing structure is arranged on the adjusting structure, a simulation structure is installed on the hydraulic machine, an auxiliary structure is installed on the simulation structure, and a telescopic device can be well kept inclined or vertical through the adjusting structure so as to achieve the effect of simulating the pressure during bridge expansion. And the fixing structure is matched to simulate a pressure bearing state when a lower water layer is arranged below the telescopic device.
Description
technical field [0001] The invention relates to the technical field of testing bridge telescopic devices, in particular to a comprehensive test bench for deformation and bearing performance of road bridge telescopic devices. Background technique [0002] Bridge telescopic device means that in order to meet the deformation requirements of the bridge deck, telescopic devices are usually installed between the two girder ends, between the girder end and the abutment, or at the hinged position of the bridge, mainly to prevent damage to the bridge body due to summer and winter temperatures. In addition, it is also necessary to ensure that the vehicle should run smoothly, without sudden jumps and noises, so the expansion device needs to have a strong compressive capacity, so the strength of the expansion device will be tested before installation, and a hydraulic press is usually used for alignment. pressure test. [0003] However, the existing hydraulic press can only squeeze in...
