Problems solved by technology

[0002] At present, the manhole covers used in municipal engineering are often circular iron covers, and the manhole covers are generally higher than the road surface. When the circular iron covers are crushed by cars for a long time, the circular iron covers will vibrate due to the unevenness of the well wall bosses. , and the vibration sound is loud, so it will cause damage to the car and the road surface, and cause sound pollution
In addition, the design and structure of the manhole cover is simple, easy to be lifted, resulting in loss

Embodiment approach

[0042]The specific implementation method is: at first the shaft wall 13 is processed into the shaft wall 13 structure with the boss in the present invention, the balance adjustment mechanism 36 is installed on the boss of the shaft wall 13, and now the support column 28 is in the fourth spring 32 and the balance The adjustment mechanism 36 is in a state of free balance under the action of gravity, the rack 20 is in a state of free balance under the action of the second spring 17, and the top of the rack 20 protrudes from the lower manhole cover 15, and the block 26 is in contact with the support column 28 under the action of the adjustment block 21. Keep a certain gap; then install the adjustment snap mechanism 35 on the balance adjustment mechanism 36, at this time, the lower end of the adjustment shell 1 in the adjustment snap mechanism 35 faces the rack 20 to generate pressure, and the rack 20 is pressed into the lower well cover In the trigger chamber 34 in 15, the downward...

Abstract

The invention belongs to the technical field of municipal engineering manhole covers, and particularly relates to a manhole cover used in municipal engineering. The manhole cover comprises a well wall, an adjustment clamping position mechanism and a balance adjustment mechanism, wherein the balance adjustment mechanism is installed on a boss of the inner round surface of the well wall, and the adjustment clamping position mechanism is installed on the upper side of the balance adjustment mechanism; and functions of prevention of thievery, height adjustment of the manhole cover, and balance adjustment of the manhole cover are achieved. Clamping strips extending out of adjusting grooves of an adjusting shell can be inserted into adjusting grooves on the well wall to play the role of definingthe up and down movement and the rotating movement of the adjusting shell and a top cover, and the manhole cover can be prevented from being prone to being lifted. The purpose of adjusting the expansion and contraction of a clamping block is achieved by inserting an auxiliary tool into a lock hole of an adjustment shaft to rotate the adjustment shaft.

Description

Technical field [0001] The invention belongs to the technical field of municipal engineering manhole covers, in particular to a manhole cover used in municipal engineering. Background technique [0002] At present, the manhole covers used in municipal engineering are often circular iron covers, and the manhole covers are generally higher than the road surface. When the circular iron covers are crushed by cars for a long time, the circular iron covers will vibrate due to the unevenness of the well wall bosses. , and the vibration sound is loud, so it will cause damage to the car and the road surface, and cause sound pollution. In addition, the design and structure of the manhole cover is simple, and it is easy to be lifted and lost. [0003] The invention designs a well cover used in municipal engineering to solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned defects in the prior art, the present invention discloses a well co...
