Clamp type manhole cover structure

Abstract

The invention discloses a clamp type manhole cover structure and relates to the technical field of manhole covers. The clamp type manhole cover structure comprises a manhole base, an installation frame is fixedly installed on the right side surface of the manhole base, a connecting plate is fixedly installed between a front side plate and a rear side plate of the installation frame through a firstrotating shaft, a manhole cover plate is fixedly installed on the lower surface of the connecting plate, an installation box is fixedly installed on the portion, close to the right side, of the uppersurface of the manhole cover plate, a clamp body is fixedly installed on the portion, close to the left side edge, of the right side face of the installation box through a second rotating shaft, theouter surfaces of the manhole base and the manhole cover plate are sleeved with the clamp body, and the other end head of the clamp body is inserted into the installation box from the front side surface of the installation box. The clamp body is used for connecting and fixing the manhole cover plate and the manhole base, so that the manhole cover plate is uniform in stress and better in tightness,the clamp body can be dismounted without other articles, the dismounting efficiency of the manhole cover plate is higher, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of manhole covers, in particular to a clamp type manhole cover structure. Background technique [0002] The manhole cover is a common part of chemical thermal equipment including boilers, reaction kettles and storage tanks. It is mainly used to facilitate the entry and exit of engineering and technical personnel during equipment maintenance or installation. Traditional manhole covers are made of metal plates. The weight is heavy and the structure is firm, especially in the occasions where temperature resistance and pressure resistance are required. However, the existing manhole covers still have the following problems during use: [0003] 1. In the existing technology, the traditional manhole cover mostly uses 8-12 eye locking bolts. It takes a lot of time to disassemble and assemble the manhole cover, and the efficiency of loading and unloading is extremely low, and the locking bolts are easy to corrode and...
