Electro-hydraulic servo pressure testing machine and cleaning protection device thereof

Abstract

The invention discloses an electro-hydraulic servo pressure testing machine and a cleaning and protecting device thereof, and particularly relates to the technical field of machines. The electro-hydraulic servo pressure testing machine comprises a supporting shell and a protecting shell, two collecting boxes are arranged in the supporting shell, and the upper surface of the supporting shell is fixedly connected with the lower surface of a supporting plate; and the upper surface of the supporting plate is fixedly connected with the lower surface of an air blowing assembly. By arranging an electric hydraulic rod, a fixing plate, a connecting rope, an air blowing assembly, a rope, a cleaning assembly and a collecting box, the device can automatically clean residues after an experiment in the process that the electric hydraulic rod drives a pressing plate to be separated from a test, large residues can be cleaned, and small particles can also be cleaned. The device is simple in structure and convenient to use, ensures thoroughness in cleaning, can collect residues, meets the use requirements, enables testing work to be easier, does not need other electric drive in the whole process, and can bring good use value.

Description

technical field [0001] The invention relates to the field of mechanical technology, more specifically, the invention relates to an electro-hydraulic servo pressure testing machine and its cleaning protection device. Background technique [0002] The pressure testing machine is an instrument for testing the compressive strength of cement and concrete. In the prior art, the pressure testing machine is generally composed of a placement table, a driving extrusion mechanism and a support. There are also the following problems in use: [0003] 1. After the pressure testing machine is used, the burst cement blocks or concrete blocks will be scattered everywhere, and it needs to be cleaned before the next test can be carried out, which is troublesome; [0004] 2. Because the extrusion area is open, when the pressure test is carried out, when the cement block or concrete block reaches the maximum strength, it will burst, and some fragments will splash and hurt people, making the safe...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electro-hydraulic servo pressure testing machine and its cleaning protection device. The technical problem to be solved by the present invention is: in the prior art, after the pressure testing machine is used, the cracked cement The blocks or concrete blocks will be scattered everywhere and need to be cleaned up before the next test can be carried out, which is troublesome, and when the pressure testing machine is performing a pressure test, when the cement blocks or concrete blocks reach the maximum strength, they will burst. Part of the fragments will splash and hurt people, making it a big safety hazard
