Description

Technical Field

[0001] This utility model relates to a pressure-resistant and earthquake-resistant manhole cover. Background Technology

[0002] Urban construction involves numerous underground pipelines, such as sewers, underground gas pipelines, water supply pipelines, power pipelines, communication pipelines, and defense pipelines. These pipelines have an outlet to the surface at intervals; this section from the pipeline to the surface is called a manhole. The manhole opening is usually flush with the ground, thus requiring a cover called a manhole cover. Generally, a manhole cover consists of a base buried in the ground and a cover plate placed within the base. Due to heavy vehicles and construction machinery passing over the manhole cover, significant pressure and vibration can easily occur, causing the connection between the cover plate and the base to loosen or the cover plate to shift. When the cover plate's bearing capacity is exceeded, it may break, affecting traffic safety. Therefore, improvements and optimizations are being made to address this issue. Utility Model Content

[0003] To solve the above problems, the technical problem to be solved by this utility model is to provide a pressure-resistant and shock-resistant manhole cover.

[0004] The technical solution adopted by this utility model of pressure-resistant and shock-resistant manhole cover is characterized by comprising a manhole cover base, a manhole cover plate, a buffer receiving sleeve, and a buffer spring. The manhole cover base includes a base receiving part with a base through hole. The base receiving part has an inner base perimeter at the base through hole, and the inner wall of the inner base perimeter has an inner base retaining edge. The buffer receiving sleeve is placed inside the inner base perimeter. The buffer receiving sleeve includes a receiving sleeve body for receiving the manhole cover plate. The receiving sleeve body has a receiving sleeve through hole communicating with the base through hole. The outer wall of the receiving sleeve body is provided with receiving sleeve limiting blocks at intervals around an arc. The manhole cover plate is provided with... The manhole cover has a cover plate socket for inserting the receiving sleeve limiting plug. The outer wall of the manhole cover plate is provided with a cover plate limiting groove that communicates with the receiving sleeve limiting plug and is used to limit the receiving sleeve limiting plug. The buffer spring is arranged in an arc between the buffer receiving sleeve and the inner edge of the base. Its upper end abuts against the lower part of the receiving sleeve body and its lower end abuts against the inner edge of the base. The receiving sleeve body is provided with a receiving sleeve threaded hole in an arc. The inner edge of the base is provided with an inner edge mating hole in an arc corresponding to the receiving sleeve threaded hole. The screw passes through the inner edge mating hole and is threadedly connected to the receiving sleeve threaded hole.

[0005] The outer wall of the receiving sleeve limiting insert is provided with a vertically arranged insert guide groove, and the inner wall of the base inner perimeter is provided with an inner perimeter guide protrusion above the inner edge of the base that is connected to the insert guide groove.

The spring limiting seats have a limiting seat receiving groove for inserting the lower end of the buffer spring. The limiting seat receiving groove has the inner edge docking hole. There are four buffer springs and four spring limiting seats.

[0009] The advantages of this pressure-resistant and shock-resistant manhole cover are as follows: After the manhole cover is subjected to pressure and shock, the impact force is transferred to the buffer spring through the buffer bearing sleeve to disperse the impact force, effectively improving the pressure and shock resistance of the manhole cover. By rotating the manhole cover, the manhole cover is tightly connected to the buffer bearing sleeve to prevent the manhole cover from falling off. Then, the manhole cover is locked by the manhole cover locking plate, hiding the fixed interface, so that there are no uneven openings on the surface, reducing the risk of vehicle bumps and improving safety.

[0017] like Figure 1-6As shown, the pressure-resistant and shock-resistant manhole cover of this utility model includes a manhole cover base 1, a manhole cover plate 2, a buffer receiving sleeve 3, and a buffer spring 4. The manhole cover base 1 includes a base receiving part 8, a base through hole 9, and an inner base perimeter 10 at the base through hole 9. The inner wall of the inner base perimeter 10 is provided with an inner base baffle 11. The buffer receiving sleeve 3 is placed inside the inner base perimeter 10. The buffer receiving sleeve 3 includes... The manhole cover plate 2 is supported by a receiving sleeve body 13. The receiving sleeve body 13 has a receiving sleeve through hole 14 communicating with the base through hole 9. The outer wall of the receiving sleeve body 13 is provided with receiving sleeve limiting inserts 15 spaced around an arc. The manhole cover plate 2 is provided with cover plate insertion openings 16 spaced around an arc for inserting the receiving sleeve limiting inserts 15. The outer wall of the manhole cover plate 2 is provided with a cover that communicates with and limits the receiving sleeve limiting inserts 15. The plate limiting groove 17, the buffer spring 4 is arranged in an arc between the buffer receiving sleeve 3 and the inner flange 11 of the base, the upper end of the spring abuts below the receiving sleeve body 13 and the lower end abuts on the inner flange 11 of the base, the receiving sleeve body 13 is provided with a receiving sleeve threaded hole 19 in an arc, and the inner flange 11 of the base is provided with an inner flange mating hole 20 in an arc corresponding to the receiving sleeve threaded hole 19, the screw passes through the inner flange mating hole 20 and then engages with the receiving sleeve. The manhole cover 2 is connected by a threaded hole 19. After being subjected to pressure and vibration, the impact force is transmitted to the buffer spring 4 through the buffer bearing sleeve 3 to disperse the impact force, effectively improving the pressure and vibration resistance of the manhole cover. By rotating the manhole cover 2, the manhole cover 2 is tightly connected to the buffer bearing sleeve 3 to prevent the manhole cover 2 from falling off or shifting. Then, the manhole cover 2 is locked by the manhole cover locking plate 5, hiding and fixing the interface, so that there are no uneven openings on the surface, reducing the risk of driving bumps and improving safety.

[0018] The outer wall of the receiving sleeve limiting insert 15 is provided with a vertically arranged insert guide groove 21, and the inner wall of the base inner perimeter 10 is provided with an inner perimeter guide protrusion 22 above the base inner stop 11 that is connected to the insert guide groove 21, so that the up and down movement of the buffer receiving sleeve 3 is more reliable.

[0019] It also includes a manhole cover locking plate 5, which includes a locking plate body 24.

The cover plate inlet 16 of the manhole cover plate 2 is connected with the receiving sleeve limiting block 15 of the buffer receiving sleeve 3. The manhole cover plate is rotated at a certain angle, so that the receiving sleeve limiting block 15 moves into the cover plate limiting groove 17, realizing the limiting function of the manhole cover plate 2, so that the manhole cover plate 2 and the buffer receiving sleeve 3 form a whole. Then, the manhole cover locking plate 5 is placed on the manhole cover plate 2, so that the locking plate locking block 25 is inserted into the cover plate inlet 16. On the one hand, the concave and convex openings on the surface of the manhole cover plate 2 are blocked, making the upper surface smooth and improving driving safety. On the other hand, it effectively prevents the manhole cover plate 2 from accidentally rotating and falling off, improving the connection safety.

[0021] The inner wall of the base inner perimeter 10 is provided with a stop block 27 at intervals around the inner side 11 of the base in an arc, which is used to limit the downward stroke of the manhole cover plate 2. This prevents the manhole cover plate 2 from being over-buffered, which would damage the buffer spring 4. This makes the buffering process controllable and effectively prevents unevenness between the manhole cover plate 2 and the manhole cover base 1, thus improving the service life.

[0022] Spring limiting seats 29 are provided at intervals around the inner edge 11 of the base in an arc. The spring limiting seats 29 are provided with limiting seat receiving grooves 30 for the lower end of the buffer spring 4 to be inserted. The limiting seat receiving grooves 30 are provided with the inner edge docking holes 20. The buffer spring 4 has directional movement, reliable movement and is not easy to shift. There are 4 buffer springs 4 and 4 spring limiting seats 29, which makes the overall buffering more stable and the force more balanced.
