A suspension device for disassembling and assembling manhole cover of chemical equipment

Abstract

The invention relates to the technical field of chemical equipment, in particular to a suspension device used for disassembling and assembling manhole covers of chemical equipment. It includes a suspension frame body, a suspension system, a clamping mechanical claw and an installation bracket. The suspension frame body is installed above several chemical equipment, the suspension system is set on the suspension frame body, and the installation bracket is installed on the suspension system. On the output end, the clamping mechanical claw is arranged on the mounting bracket, and the clamping mechanical claw includes a push mechanism, a manhole cover clamping mechanism for clamping and moving the manhole cover, and a manhole for clamping the manhole The outer wall clamping mechanism, the pushing mechanism is installed on the mounting bracket, and the pushing mechanism is provided with two output ends with opposite outputs. The manhole cover clamping mechanism and the manhole outer wall clamping mechanism are respectively installed on the two output ends of the pushing mechanism. superior. The hoisting device shown in the present application can quickly and accurately disassemble and assemble the manhole cover on each chemical equipment, and detect whether it contains toxic gas when the manhole cover is opened, which improves the safety performance and the disassembly and assembly efficiency.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a suspension device used for disassembling and assembling manhole covers of chemical equipment. Background technique [0002] Manhole cover refers to the general term for the cover plate with sealing performance and its fixing accessories installed on the manhole. The manhole cover can be divided into protruding type and buried type according to whether it is higher than the opening surface after installation. [0003] Chinese Patent Publication No. CN103624511A shows a suspender device for a cone shell, including a suspender arm and an adjustable structure; the suspender arm is bent, including a horizontal part parallel to the ground and a vertical part perpendicular to the ground The vertical part is detachably mounted on the manhole flange; the horizontal part is connected with the manhole cover through the adjustable structure, and the adjustable structure can mak...

Problems solved by technology

[0004] However, the above-mentioned device cannot be quickly switched among multiple chemical equipment. After the installation is completed, only one specific manhole cover of one of the chemical equipment can be disassembled and installed. The manhole cover, in a specific area with multiple chemical equipment such as a processing workshop, needs to be repeatedly disassembled and assembled during use, which is time-consuming and labor-intensive, and when the chemical equipment opens the manhole cover, there may be residual harmful gas leakage. The above-mentioned device Unable to detect harmful gases, which has certain potential safety hazards
