Safe anti-theft municipal well lid, disassembling tool and disassembling and assembling method

Abstract

The invention provides a safe anti-theft municipal well lid, a disassembling tool and a disassembling and assembling method, and belongs to the field of municipal engineering equipment. According to the well lid, the disassembling tool and the disassembling and assembling method, the problem that an existing well lid is troublesome to disassemble and assemble is solved. The safe anti-theft municipal well lid comprises a well seat and a well lid body, wherein a baffle ring is arranged on the inner wall of the well seat, an annular locking groove is formed in the inner wall of the baffle ring, and disassembling holes are formed in the well lid body; the well lid further comprises connecting plates, limiting plates and connecting sleeves; wherein the outer edges of the connecting plates and the outer edges of the limiting plates are fixed to the top ends and the bottom ends of the connecting sleeves correspondingly, and the connecting plates are fixed on the bottom surface of the well lidbody; the well lid further comprises upper hinge seats, wherein the top ends of the upper hinge seats are fixed on the bottom surfaces of the connecting plates, the bottoms of the upper hinge seats are movably connected with lower hinge seats, and the axes of connecting shafts are parallel to the axis of the well lid body; the well lid also comprises lock rods fixed to the lower hinge seats, thelock rods are parallel to the bottom surface of the well lid body, the connecting shafts are sleeved with torsion springs, wherein the two ends of the torsion springs are fixed to connecting grooves and the connecting shafts correspondingly; and a rod hole is formed in the sleeve wall of each connecting sleeve. The well lid is good in anti-theft performance and convenient to assemble and disassemble.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering equipment, and relates to a safe and anti-theft municipal manhole cover, a disassembly tool and a disassembly method. Background technique [0002] Existing manhole covers are generally pulled up and opened by disassembly tools, which is difficult to disassemble, resulting in poor anti-theft performance. At the same time, when the manhole cover is being maintained, a deep well will be formed on the road surface, so that passing pedestrians or vehicles will fall into the deep hole inadvertently , a security incident occurred. [0003] The existing application number is 201610893655.5, which is a Chinese invention patent named "An Anti-theft Municipal Manhole Cover Disassembly Structure". , screw the disassembly rod to the disassembly hole, and make the disassembly rod press down on the cover plate, so that the steel plate rotates around the pin shaft and separates from the slot to di...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the cover body is often under pressure and the use environment is complex, the internal thread of the disassembly hole is easily damaged by pressure or corrosion, and it is extremely difficult to keep it intact. After damage, it cannot be used to install and disassemble the rod;

[0005] 2. Due to the need for multiple disassembly rods to cooperate, it is necessary to screw and fix the disassembly rods one by one, and the disassembly process is very troublesome;

[0006] 3. After the cover body is installed on the well seat, it is impossible to position and install the cover body, which leads to the inability to match the card groove and the steel plate in sequence, so it is necessary to align the card groove and the steel plate, resulting in troublesome installation; therefore, it is necessary to improve
