Embodiment 1

[0024] refer to Figure 1-5 , an adjustable anti-settling manhole cover used in municipal engineering, comprising a manhole cover body 1, a support seat 2 is installed at the bottom of the manhole cover body 1, a receiving seat 5 is installed at the bottom of the support seat 2, and the outside of the top of the receiving seat 5 is evenly installed along the circumferential direction. A fixed frame 15, the inner side of the top of the receiving seat 5 is evenly provided with a plurality of chute 13 along the circumferential direction, the position of the chute 13 corresponds to the position of the fixed frame 15, and the cross-sectional size of the fixed frame 15 is the same as that of the chute 13 The size matches, and the limit plate 10 is slidably installed inside the fixed frame 15, and the limit mechanism is installed between the well cover body 1 and the limit plate 10. The limit mechanism includes a limit ring 7 and a limit groove 8, and the limit ring 7 is installed on ...

Embodiment 2

[0028] refer to Figure 2-4 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that positioning blocks 9 are installed on both sides of the top of the receiving seat 5, positioning grooves 6 are opened on both sides of the bottom of the well cover body 1, and the positioning grooves 6 The position corresponds to the position of the positioning block 9, and the size of the positioning block 9 matches the size of the positioning groove 6. Through the mutual clamping of the positioning block 9 and the positioning groove 6, the alignment of the well cover body 1 can be completed when the well cover body 1 is installed. The preliminary positioning of the well cover body 1 facilitates the subsequent adjustment operation of the position of the well cover body 1, reduces the installation difficulty of the well cover body 1, and can improve the installation stability of the well cover body 1.

Abstract

The invention relates to the technical field of anti-settling well lids, and particularly relates to an adjustable anti-settling well lid for municipal engineering. The adjustable anti-settling well lid comprises a well lid body, wherein a supporting seat is mounted at the bottom of the well lid body; a bearing seat is mounted at the bottom of the supporting seat; a plurality of fixing frames are uniformly mounted on the outer side of the top of the bearing seat circumferentially; a plurality of sliding grooves are uniformly formed in the inner side of the top of the bearing seat circumferentially; the sliding grooves are in one-to-one correspondence to the fixing frames in position; section size of each fixing frame is matched with that of the corresponding sliding groove; a limiting plate is slidably mounted inside each fixing frame; a limiting mechanism is mounted between the well lid body and each limiting plate; a clamping groove is formed in the supporting seat; a clamping ring is connected inside the clamping groove in a clamped manner; an adjusting mechanism is mounted between the clamping ring and each limiting plate; a plurality of positioning holes are uniformly formed in the clamping ring circumferentially; and a plurality of positioning bolts are uniformly mounted on the outer side of the supporting seat circumferentially and correspond to the positioning holes in position. The adjustable anti-settling well lid is convenient to adjust and prevented from settling.

Description

technical field [0001] The invention relates to the technical field of anti-settling well covers, in particular to an adjustable anti-settling well cover used in municipal engineering. Background technique [0002] Manhole covers are generally round and used for green belts, sidewalks, motorways, docks, etc., to cover roads or deep wells to prevent people or objects from falling. The existing manhole covers can be divided into single-layer, double-layer, cast iron, and ductile cast iron. , composite, cement, etc., but no matter what kind of manhole cover is in use, most of the manhole cover settlement will occur. The manhole cover settlement is due to the uneven force on the manhole cover when the car passes by, resulting in excessive local stress on the manhole cover. Long-term The sinking phenomenon of the manhole cover after use will lead to depressions on the road surface, which will affect the normal use of the manhole cover and the driving of vehicles.
