Tangential displacement testing device for building shock insulation rubber pipe

Abstract

The invention discloses a tangential displacement testing device for a building shock insulation rubber pipe, which comprises a rack, a vertical mounting seat and a horizontal mounting seat. A limiting sliding plate is fixedly arranged above the vertical mounting seat, a first hydraulic cylinder is fixedly arranged above the rack, and the free end of the first hydraulic cylinder passes through therack and is fixedly connected with the sliding plate; a sliding block is fixedly arranged below the horizontal mounting seat, the sliding block is in sliding connection with a horizontal sliding railbelow the rack, a second hydraulic cylinder is fixedly arranged on one side of the rack, and the free end of the second hydraulic cylinder penetrates through the rack and is fixedly connected with the horizontal mounting seat; mounting holes are arranged in the opposite surfaces of the vertical mounting seat and horizontal mounting seat, and the mounting holes are matched with an end socket of the building shock insulation rubber pipe to be tested. The structure achieves the independent loading in the horizontal direction and the vertical direction and also achieves the loading in the vertical direction and the horizontal direction simultaneously; so that the simulation of various use conditions is achieved, the accuracy of a test result is improved, and the performance monitoring of damage, fatigue and the like of a pipe is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pipe detection, and in particular relates to a device for testing the tangential displacement of a building shock-isolation rubber pipe. It is used to simulate the tangential displacement compensation of seismic isolation rubber pipes used in buildings during earthquakes, so as to test the expected life and fatigue coefficient of pipes under corresponding conditions. Background technique [0002] Most of the building isolation rubber pipes are buried in the ground and are greatly affected by stratum changes. When the earthquake or formation changes, the pipe will be subjected to corresponding force changes. However, the change of formation is uncertain, not only will there be horizontal stretching or compression, but also vertical rise or fall. Therefore, the effect on the tubing is a combination of axial and radial. [0003] The existing pipe testing device has the following disadvantages: 1. It can o...

Problems solved by technology

[0003] The existing pipe testing device has the following disadvantages: 1. It can only test the physical properties such as tension and compression in the axial direction of the pipe, and cannot effectively simulate the situation that the pipe is subjected to the combined force of the axial and radial directions, which affects the test. Accuracy; 2. The existing test device has a single function and does not have the function of one machine with multiple functions; 3. The tangential displacement rate of the existing test device is low, which cannot reach the required 400mm / s, especially when reversing , the time is long and the speed is slow, which affects the test results
