Microcomputer servo control bridge expansion joint performance tester

Abstract

The invention discloses a microcomputer servo control bridge expansion joint performance tester which comprises a base, a first moving beam and a second moving beam; the first moving beam and the second moving beam are arranged on the base; a first drive device used for driving the first moving beam to move in a width direction of the base is arranged between the first moving beam and the base; asecond drive device used for driving the second moving beam to move in a length direction of the base and a third drive device used for driving the second moving beam to move in the length direction of the base are arranged between the second moving beam and the base; and the upper side of each of the first moving beam and the second moving beam is provided with a friction tester and a pressure tester. The microcomputer servo control bridge expansion joint performance tester provided by the invention can perform comprehensive performance detection on the bridge expansion joint performance, isconvenient to operate and can ensure the accuracy of detection data of the bridge expansion joint performance.

Description

technical field [0001] The invention relates to the technical field of test equipment, in particular to a performance test device for bridge expansion joints controlled by a microcomputer servo. Background technique [0002] Bridge expansion joints refer to the connectors that are usually installed between the two girder ends, between the girder end and the abutment, or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. Displacements and linkages between the superstructure due to loads and bridge construction materials. For bridge expansion joints that are not of sufficient quality, if they are applied to actual road and bridge construction, the breakage of the bridge expansion joints will cause huge losses before the service life is reached, and it will also pose a threat to the lives of passing vehicles and pedestrians. Therefore, the performance test of bridge expansion joints is very important, and there are relevant i...

Problems solved by technology

For bridge expansion joints that are not of good quality, if they are applied to actual road and bridge construction, the breakage of the bridge expansion joints before reaching the service life will cause huge losses and cause life threats to passing vehicles and pedestrians.

Therefore, the performance test of bridge expansion joints is very important, and there are relevant industry standards for the performance test of bridge expansion joints, but the test tools in the industry standards are relatively simple, which will not only make the test process more cumbersome, difficult to operate, but also cause test data.
