Abstract

The invention relates to manhole cover plate locating devices and provides an internal pressure type manhole cover plate locating device in order to solve the problems that an existing high-pressure vessel internal pressure type manhole cover plate locating device is heavy in weight and difficult and complex in assembling and reassembling process, needs to be manually adjusted each time and is untight due to inaccurate locating. The internal pressure type manhole cover plate locating device comprises a cover plate fixing strip, a rotating shaft, a base plate, a positioning bolt, a support, a crank arm, a rotary shaft, a rocking handle and a connecting piece. The positioning bolt is in threaded connection with the base plate. The rotating shaft is fixedly mounted at one end of the crank arm. The top end of the positioning bolt abuts against the rotating shaft. The other end of the crank arm is rotatably connected with one end of the cover plate fixing strip through a first pin shaft. The other end of the cover plate fixing strip is rotatably connected with one end of the connecting piece through a second pin shaft. The other end of the connecting piece is connected with the rockinghandle. The rocking handle is rotatably connected with the curved portion of the crank arm through the rotary shaft. The cover plate fixing strip is mounted on a manhole cover plate. The manhole coverplate is mounted on a manhole base. The internal pressure type manhole cover plate locating device is applied to the field of internal pressure type manhole cover plate installation.

Description

technical field [0001] The invention relates to a manhole cover plate positioning device, in particular to an internal pressure type manhole cover plate positioning device. Background technique [0002] Existing high-pressure vessels and heat exchangers (such as high-pressure heaters, high-pressure boiler drums, and steam generators for photothermal power generation) usually use internal pressure manhole covers, and the manhole covers are tightly pressed against the manhole cover by using the high pressure inside the boiler. On the hole seat to ensure the sealing effect. The manhole is the access to the inside of the equipment for inspection and maintenance. In order to enter the manhole, the manhole door has to be disassembled, and for a high-pressure vessel with an internal pressure manhole cover, because the manhole cover is heavy, it is difficult to complete the disassembly without other auxiliary tools. At the same time, compared with the disassembly process, the reas...
