Manhole cover performance testing equipment

Abstract

The invention discloses manhole cover performance testing equipment. The manhole cover performance testing equipment comprises a machine frame, wherein an L-shaped groove is formed in the right end ofthe machine frame, a supporting plate is fixed at the bottom end of the side wall of the L-shaped groove, a block groove is formed in the middle of the top end of the supporting plate, one end of theinterior of the block groove is provided with an electro-hydraulic push rod, a sliding block is fixed on a push rod of the electro-hydraulic push rod, the sliding block is located in the block groove, a side wall of the sliding block is connected with the push rod of the electro-hydraulic push rod, a lifting shell is fixed at the top end of the sliding block, a hydraulic cylinder is arranged at the bottom end inside the lifting shell, a piston rod of the hydraulic cylinder penetrates through the top end of the lifting shell, and the tail end of the piston rod of the hydraulic cylinder is fixed at the bottom end of a detection tank. The detection tank is arranged at the top of the hydraulic cylinder, the manhole cover is placed on a detection disc, so that the hydraulic cylinder is used for driving the manhole cover to be tightly connected with the detection disc, so that the installation time is greatly prolonged, the subsequent detection efficiency is improved, and the manhole coverperformance testing equipment is suitable for being widely popularized and used.

Description

technical field [0001] The invention relates to a testing device, in particular to a performance testing device for a manhole cover. Background technique [0002] At present, there are many applications of manhole covers, which are generally used on storage tanks. Manhole covers are also called normal pressure manhole covers and quick opening manholes. Most chemical vehicle manhole covers are flange manhole covers. The cover is installed on the top of the tank body of the chemical truck. It is a passage for people to enter and exit the tank, and an observation port for checking the goods and the natural conditions inside the tank. Especially when manhole covers transport dangerous or volatile objects, extra care is required. Test the sealing and pressure performance of the manhole cover, and check whether the manhole cover is up to standard through different pressure tests. At present, there is no equipment that can quickly detect whether the manhole cover meets the specific...

[0002] At present, there are many applications of manhole covers, which are generally used on storage tanks. Manhole covers are also called normal pressure manhole covers and quick opening manholes. Most chemical vehicle manhole covers are flange manhole covers. The cover is installed on the top of the tank body of the chemical truck. It is a passage for people to enter and exit the tank, and an observation port for checking the goods and the natural conditions inside the tank. Especially when manhole covers transport dangerous or volatile objects, extra care is required. Test the sealing and pressure performance of the manhole cover, and check whether the manhole cover is up to standard through different pressure tests. At present, there is no equipment that can quickly detect whether the manhole cover meets the specifications to deal with such problems, resulting in The safety of the manhole cover cannot be guaranteed. In order to solve the above-mentioned problems, we propose a manhole cover performance testing equipment
