Technical Field

[0001] The utility model relates to the technical field of municipal engineering equipment, in particular to a special manhole cover for preventing vehicle bounce and noise. Background Technique

[0002] The manhole cover is used to cover roads or deep wells at home to prevent people or objects from falling. Generally, it is circular and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] After the manhole cover is installed and used for a period of time, due to the manhole cover being rolled by wheels, the manhole cover and the manhole cover seat are worn. After long-term wear and aging and cracking, after replacing the new manhole cover, because the new manhole cover and the old manhole cover seat are not cast and formed by the same set of models, the horizontal gap between the manhole cover and the manhole cover seat is large and the vertical height is uneven; or because after the manhole cover is opened by construction or maintenance personnel and then restored, it is difficult to put it back to its original position, resulting in unevenness between the manhole cover and the manhole cover seat, and causing the manhole cover to bounce or jump off, which seriously affects road safety and at the same time generates abnormal noise, affecting the lives of nearby residents; generally, the long-term method to solve the frequent occurrence of manhole cover bounce and noise is to replace the qualified manhole cover, but the quantity is huge and it is difficult to achieve in the short term.

[0004] Therefore, this application proposes a special manhole cover for preventing vehicle bounce and noise, which is used to solve the abnormal noise generated by the manhole cover due to bounce and solve the noise problem. Content of the Utility Model

[0019] Please refer toFigures 1-2 , an embodiment of the present utility model provides a special manhole cover for preventing vehicle jumping and rattling, including a manhole cover 1 and a manhole cover seat 2. The manhole cover seat 2 and the manhole cover 1 are connected through a connecting member. The function of hinging between the manhole cover seat 2 and the manhole cover 1 is realized through the connecting member 3, which is the prior art and will not be elaborated here; a circumferential ring of horizontal annular clamping platforms 4 is fixedly arranged on the inner circumferential wall surface of the manhole cover seat 2. The annular clamping platforms 4 are used to cooperate with the manhole cover 1 to realize the closed state between the manhole cover 1 and the manhole cover seat 2, that is, to realize the covering of the wellhead;

[0020] An arc-shaped shock-absorbing strip 5 is fixedly arranged on the annular clamping platform 4 through a viscous filling paste. There are four arc-shaped shock-absorbing strips 5. The four arc-shaped shock-absorbing strips 5 enclose a ring on the annular clamping platform 4, that is, a circumferential shock-absorbing strip is arranged between the annular clamping platform 4 and the bottom surface of the manhole cover 1 to reduce the abnormal noise generated by the collision between the manhole cover 1 and the manhole cover seat 2 due to the jumping of the manhole cover 1.

[0021] In a preferred embodiment, the arc-shaped shock-absorbing strip 5 includes an arc-shaped top plate 51 attached to the top surface of the annular clamping platform 4. An integrally formed arc-shaped side plate 52 is fixedly arranged on the inner circumferential surface of the arc-shaped top plate 51. The arc-shaped side plate 52 and the arc-shaped top plate 51 are perpendicular to each other; a plurality of convex blocks 53 are evenly fixedly arranged on the bottom surface of the arc-shaped top plate 51 to increase the contact area with the viscous filling paste, thereby improving the stability of the arc-shaped shock-absorbing strip 5 after installation.

[0022] Preferably, an arc-shaped clamping plate parallel to the arc-shaped side plate 52 is fixedly arranged on the bottom surface of the arc-shaped top plate 51. The arc-shaped clamping plate and the arc-shaped side plate 52 are arranged in the same direction, and both are arranged with the bottom surface of the arc-shaped top plate 51 perpendicular downward.

[0023] An annular groove is arranged on the annular clamping platform 4 for clamping the arc-shaped clamping plate to improve the stability of the arc-shaped shock-absorbing strip 5 after installation; the height of the arc-shaped clamping plate is greater than the height of the convex blocks 53. After the arc-shaped clamping plate is embedded into the annular groove, the convex blocks can be in contact with the top surface of the annular clamping platform.

[0024] Among them, the viscous filling paste cooperates with the arc-shaped shock-absorbing strip on the annular clamping platform and hardens in the air after a certain time, stably fixing the arc-shaped shock-absorbing strip on the annular clamping strip.

[0025] In a preferred embodiment, the viscous filling paste includes a viscous filling dry material, and the viscous filling dry material is prepared from component A and component B in a mass ratio of 1:0.7; the viscous filling dry material reacts with water to form the viscous filling paste.

[0026] In a preferred embodiment, Component A is a dry powder mixed by sulfoaluminate cement, water reducing agent, setting regulator and rubber particles, wherein the mass ratio of sulfoaluminate cement to rubber particles, water reducing agent and setting regulator is 1:(0.6 - 0.9):(0.05 - 0.3):(0.05 - 0.3);

[0027] In a preferred embodiment, Component B is epoxy resin.

[0028] Among them, the mass ratio of the dry powder of the viscous filler to water is 1:(0.3 - 1.2).

[0029] Before stirring with water, the temperatures of the dry powder of Component A and the epoxy resin of Component B should be (20 ± 2) °C. Add the dry powder mixed by sulfoaluminate cement, water reducing agent, setting regulator and rubber particles and the epoxy resin into water, and stir for 10 - 60 minutes until it becomes uniform and has a certain fluidity, obtaining a viscous filler slurry, which has advantages such as support and shock absorption.

[0030] In a preferred embodiment, the rubber particles are made by crushing waste rubber to obtain rubber particles with different particle sizes.

[0031] In a preferred embodiment, the arc-shaped shock-absorbing strip 5 is made of rubber material.

[0032] After installing the well cover seat and the well cover, fix the arc-shaped shock-absorbing strip on the annular clamping platform through the viscous filler to ensure that when the well cover jumps, abnormal noise is avoided between the well cover and the well cover seat; in addition, this method of shock absorption and noise avoidance can be applied to the already installed well cover. Just fix the arc-shaped shock-absorbing strip on the well cover seat through the viscous filler slurry, and the function of preventing jumping and abnormal noise can be achieved, avoiding the generation of noise.
