Pressure tester

Abstract

The invention discloses a pressure tester which comprises a pedestal, wherein struts are symmetrically arranged at two ends of the pedestal, the struts are used for supporting a top seat and fixing the top seat to the upper end of the pedestal, two bases are transversely arranged side by side on the upper end face of the pedestal, a test bed is fixedly connected to each base, first through holes corresponding to the two test beds are formed in the top seat, hydraulic cylinders are mounted on the top seat through mounting seats, a lower pressure block is concentrically arranged on one end, closed to the test beds, of a piston rod of each hydraulic cylinder, positioning devices for positioning a test piece are arranged at the upper ends of the test beds, a push device connected to a box is arranged on one side of the pedestal, and a cleaning mechanism is arranged on the other side of the pedestal. By adopting the pressure tester, test pieces of different sizes can be positioned; the cleaning device has a relatively good cleaning effect, and the two test beds are arranged to switch between test and cleaning, so that the cleaning effect is relatively good and the test efficiency is relatively high.

Description

technical field [0001] The invention relates to the technical field of testing machines, in particular to a pressure testing machine. Background technique [0002] The testing machine, also known as the electronic pressure testing machine, is mainly suitable for various physical and mechanical performance tests of concrete, rubber, plastic sheets, pipes, profiled materials, material films, wires and cables, waterproof coils, metal wires, cartons, pallets and other materials; With the improvement of construction technology, the country accelerates the construction of infrastructure projects, and the application of concrete in the construction market is increasing. In construction projects, it is usually necessary to regularly test the performance of concrete. The method is to cast a batch of specified sizes The cube concrete test blocks are squeezed by a pressure testing machine until the test blocks are broken, and various data values ​​are obtained.

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned pressure testing machines are not equipped with a positioning mechanism for concrete test pieces. When testing the performance of concrete test pieces, test pieces of different specifications are often tested. The types of test pieces include cubes, cuboids and cylinders. When concrete If the size of the test piece is small, it will easily cause the concrete test piece to fall during the test; if the size of the concrete test piece is large, it will easily cause the concrete test piece to slip from the test bench during the test. The positioning of the concrete test piece will cause poor results due to inaccurate positioning, and the above situations will affect the test results; the cleaning mechanism of the above-mentioned pressure testing machine cannot clean the dust generated during the experiment, and the cleaning effect is poor. At the same time, when the pressure testing machine After the first experiment, the test bench needs to be cleaned first, and the second test can only be carried out after the test bench is cleaned, resulting in low test efficiency
