Description

Technical Field

[0001] The utility model relates to the technical field of bridge support detection, in particular to a vertical bearing capacity testing device for a bridge basin-type support. Background Art

[0002] The pot bearing is a new type of bridge bearing composed of steel components and rubber. The main function of the pot bearing is to reliably transmit the reaction force of the upper pier structure to the lower pier, and at the same time be able to adapt to the deformation bearing capacity required by the bridge structure. Before use, it is necessary to use a press to test the vertical bearing capacity of the pot bearing. During the test, the staff will carry the pot bearing to the load-bearing trolley on the guide frame of the press, and adjust the pot bearing to the central position of the load-bearing trolley, push the load-bearing trolley to the center of the press, start the hydraulic cylinder of the press to lift the load-bearing trolley and the pot bearing, and contact with the top plate of the press for pressure testing. After the hydraulic cylinder is loaded with different levels of pressure, the deformation of the pot bearing is tested to see if it meets the requirements;

[0003] In the prior art, since the pot-type support is heavy, it usually takes two people to lift the pot-type support and place it on the carrying trolley, which is laborious and poses certain safety hazards. At the same time, after placement, personnel need to use a steel ruler to measure and adjust the position of the pot-type support on the carrying trolley and place it in the center (the deformation data of the test is more accurate when the force is not biased during the experiment). This adjustment takes a long time, which leads to low efficiency of the test as a whole. In response to the above problem, the document with application number: 202221586051.3 discloses a vertical bearing capacity test device for a bridge pot-type support, which includes a pressure testing machine for testing the bearing capacity of the pot-type support, a guide rail frame is provided on the pressure testing machine, and a carrying trolley for moving and placing the pot-type support is provided on the guide rail frame, and a cantilever crane for lifting the pot-type support is provided on the outside of the guide rail frame. The cantilever crane lifts the pot-type support onto the carrying trolley through the electric hoist on the top and accurately positions the pot-type support in the center of the carrying trolley through the limiter provided on the guide rail frame.

[0004] However, a thorough reading of the above patent documents reveals the following problems: when in use, not only does it require the steel wire rope to be set at the center of the bridge pot support, which has certain limitations, but also the placement of the bridge pot support requires the assistance of staff, resulting in cumbersome operating steps, time-consuming and labor-intensive operations, and low work efficiency.
