Abstract

The invention provides an inward-opening type self-tightening quick-opening manhole device and system. The device comprises a connecting pipe, an outer cover, an inner plate, a sealing gasket, a rocker arm assembly, a stud and a nut. The inner plate and the outer cover are located on the inner side and the outer side of the connecting pipe correspondingly, and the sealing gasket located between the connecting pipe and the inner plate is pressed through the stud and the nut. The inner side of the outer cover is connected with a supporting plate. The connecting pipe is connected with a container, and a first handle is welded on the outer wall. The outer side of the manhole inner plate is connected with a second handle and a guide plate, and the inner side is connected with the rocker arm assembly. The rocker arm assembly comprises a connecting plate, rotating sleeves, a positioning assembly, a rocker arm, a fixed plate and a reinforcing plate and is located on the inner side of the container. The connecting plate is connected with the inner plate, the two ends of the rocker arm are connected with the rotating sleeves, and a cylindrical shaft penetrates the connecting plate and the rotating sleeves to connect the rocker arm with the inner plate and is positioned through the positioning assembly. The fixed plate is connected with the wall of the container, stability is enhanced through the reinforcing plate, and the fixed plate and the rotating sleeves are connected through the cylindrical shaft. According to the device, self-tightening sealing can be realized under internal pressure.

Description

Technical field[0001]The invention relates to the technical field of manholes, in particular to an internally opening self-tightening quick opening manhole device and system.Background technique[0002]Manhole refers to an opening structure used for personnel to enter and exit equipment for installation, maintenance and safety inspection. It is widely used in pressure vessels such as tanks. The traditional manhole is generally connected with a short section or a pipe on the outside of the container, and the outer end is connected with a flange. The manhole cover is fastened to the flange by bolts or clamps to play the role of opening and sealing. In this way, the high pressure generated inside the container will be borne by the bolts or clamps, causing the manhole device to be cumbersome, and the disassembly and assembly procedures during opening and closing are complicated, which reduces the usability. For this reason, we provide an internal opening self-tightening quick opening manh...
