AI Technical Summary

Technical Problem

The existing temporary isolation device for natural gas ground engineering construction is highly fixed during handling, which leads to difficulty in handling, and the structure cannot be folded, occupying a large space, and the connection process is cumbersome, which is time-consuming and labor-consuming.

Method used

A temporary isolation device including a base assembly and a top plate assembly is designed. The structure composed of hinges and bolts, latches and snaps allows the device to fold under gravity. The base and top plate realize telescopic function through a hinge frame and a telescopic frame. The universal wheel and rotary screw improve the stability and convenience of the device.

Benefits of technology

The isolation device is easily installed and disassembled, which reduces the difficulty of handling, reduces the height through the folding structure, simplifies the connection process, and improves the stability and transportation convenience of the device.

Abstract

The utility model discloses a temporary isolation device for natural gas ground engineering construction, which comprises a base assembly, a top plate assembly is mounted on the outer wall of one side of the base assembly through a hinge, two buckles are mounted on the outer wall of one side of the top plate assembly through bolts, and two latches are mounted on the outer wall of one side of the base assembly through bolts. One end of the latch is clamped to the buckle, two fluorescent stickers are bonded to the outer wall of one side of the top plate assembly, two reflective stickers are bonded to the outer wall of one side of the base assembly, and the base assembly comprises a first base and a second base; when the device needs to be carried, one end of the latch can be opened, so that a structure formed by the latch and the buckle does not limit the base assembly and the top plate assembly, and then because one side of the top plate assembly is not limited any more, the top plate assembly can fall down under the action of gravity, so that the isolation device is folded from the upper part; the height of the folding device is reduced, and the problem that the isolation device is difficult to carry is solved.
