Problems solved by technology

Existing test pits are usually built in the workshop, and there is no protective device on the upper part. Due to the high pressure inside the equipment, if there is an operation error or the internal pressure exceeds the limit of the equipment itself during the pressure test, equipment parts may appear. Falling off produces a super impact force, which may easily cause loss of equipment outside the test pit and casualties, and does not comply with safety production regulations

Abstract

The invention discloses a pressure test pit. The pit comprises a pit body, a folding-type pit cover and a pit cover driving mechanism, wherein the folding-type pit cover is arranged at the upper part of the pit body in a sliding manner and comprises a positioning end and a driving end; the positioning end of the folding-type pit cover is movably connected to the end part of the pit body; and the driving end of the folding-type pit cover is movably connected with the pit cover driving mechanism. According to the pressure test pit, firstly automatic opening and closing of the pit body can be quickly realized and secondly the pit body can be enabled to be in a relatively sealed state during testing, so that a situation caused by accidental injury is instantly compressed in the pit body and the pressure test risk is lowered.

Description

technical field [0001] The invention relates to the technical field of pressure testing, in particular to a pressure testing pit. Background technique [0002] The pressure test pit is a place for the factory to conduct pressure tests on the equipment that needs to be tested. It is usually a square inner pit, standing below the ground. Existing test pits are usually built in the workshop, and there is no protective device on the upper part. Due to the high pressure inside the equipment, if there is an operation error or the internal pressure exceeds the limit of the equipment itself during the pressure test, equipment parts may appear. If it falls off, it will generate a super strong impact force, which will easily cause the loss of equipment outside the test pit and casualties, and it does not meet the safety production regulations. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, ...
