Jack static load test bench

Abstract

The embodiment of the invention discloses a jack static load test bench. The jack static load test bench comprises an upper cross beam, a lower cross beam, a limiting member, a vertical pull rod and aload cell, wherein a test jack and the load cell are placed between the upper cross beam and the lower cross beam, the vertical pull rod is connected with the upper cross beam and the lower cross beam for bearing a loading force of the test jack, the limiting member is arranged between the upper cross beam and the lower cross beam, the stress condition of the limiting member and the number of thevertical pull rods are changed by changing the connection mode of the limiting member and the cross beams, and the carrying capacity of the jack static load test bench can be changed. Therefore, thejack static load test bench disclosed by the embodiment of the present invention is compact in structure, light in weight, convenient to install and adjust, clear in load transmission path, and wide in applicability.

Description

technical field [0001] The invention relates to the technical field of jack static load test, in particular to a jack static load test bench. Background technique [0002] In the static load or dynamic load test of structural parts such as bridges and floor slabs, jacks are often used to load the tested structural parts to check the mechanical properties of the structural parts. Before the test, it is necessary to test the loading capacity of the jack used in the test, and the static load test bench is a device for testing the loading capacity of the test jack. Most of the jack static load test benches in the prior art are column-type ordinary steel frame structure test benches designed with the principle of internal force self-balancing. The poured thick steel plate is used as the loading table and connected to the solid round steel column, and the round steel column is connected to the loading table. The nut needs to be specially made, the structure is heavy, and it is in...

Problems solved by technology

Most of the jack static load test benches in the prior art are column-type ordinary steel frame structure test benches designed with the principle of internal force self-balancing. The poured thick steel plate is used as the loading table and connected to the solid round steel column, and the round steel column is connected to the loading table. The nut needs to be specially made, the structure is heavy, and it is inconvenient to disassemble and transport

Moreover, the test bench in the prior art improves the load-carrying capacity of the test bench by thickening the loading table and thickening the vertical tie rods, and the cost is relatively high
