[0002] A manhole cover is a device used to cover a deep well on a road or in a home. Its main function is to prevent people or objects from falling. Manhole covers can be seen everywhere in roads, alleys, sidewalks and other places in the city, and they play an important role in ensuring public safety. During the installation of the manhole cover, the manhole cover support needs to be fixed to the ground and fixed with concrete.

[0003] After the existing manhole cover support is installed, there will be gaps due to poor internal connection stability.

[0007] A further improvement to the above solution is that a rough surface is provided on the surface of the installation step opposite to the material outlet.

[0008] A further improvement to the above solution is that a positioning metal ring is provided on the lower side of the installation step, and the positioning metal ring is used for assembling the positioning ring for positioning.

[0009] A further improvement to the above solution is that a support platform is provided on the inner periphery of the manhole cover support seat and the connection and installation portion, and the support platform is used for placing the manhole cover.

[0010] A further improvement to the above solution is that a separation ring is provided between the support platform and the rotating groove.

[0012] A method for assembling a manhole cover support seat, comprising the manhole cover support seat assembly mechanism; the assembly method comprises the following steps: Step S1, pit digging and construction: planning the location where the manhole cover needs to be constructed, and then preparing the installation wellhead on the construction carrier by using mud and sand concrete; Step S2, assembling the manhole cover support seat: waiting for the installation manhole on the building carrier to solidify, and after solidification, placing the manhole cover support seat on the installation manhole for assembly; Step S3, injecting asphalt material: after completing the assembly of the manhole cover support seat, injecting asphalt material on the rotating groove, and the asphalt material is discharged from the material outlet to fill the gap between the installation step and the connecting installation part; Step S4, asphalt extrusion: after the gap filling is completed, an extrusion element is installed on the rotating trough, and the rotating ring is rotated to drive the push plate to rotate on the rotating trough, so as to squeeze out the asphalt material in the rotating trough, further seal and fill the gap between the installation step and the connecting installation part, and block the material outlet by the push plate; Step S5, asphalt solidification: After waiting for the asphalt to solidify, remove the extrusion element from the rotating groove, and cover the upper surface of the rotating groove and the fixed outer ring with mud and sand concrete, so that the manhole cover support seat is buried at the installation wellhead.

[0013] A further improvement to the above scheme is that in step S1, when preparing and constructing the installation wellhead, a rough gravel surface is reserved on the wall surface of the installation step.

[0014] A further improvement to the above scheme is that in step S3, liquid asphalt is poured into the rotating trough, and the gap between the installation step and the connecting installation part is filled by the liquid asphalt flowing on the rotating trough.

[0015] The beneficial effects of the present invention are: Compared with the existing installation of the manhole cover support seat, the present invention effectively improves the installation stability and load-bearing capacity of the manhole cover support seat through the precise matching of the manhole cover support seat and the building carrier installation wellhead, especially the close fit between the assembly positioning ring and the bottom of the installation wellhead, and the design that the connecting and mounting part abuts against the installation step. This design not only ensures the safety of the manhole cover in daily use, but also effectively resists the influence of external environmental factors (such as wind and rain erosion, vehicle rolling, etc.) on the structural integrity of the manhole cover. The design of the rotating groove and the extrusion element greatly simplifies the installation process of the manhole cover support seat. The extrusion element includes a swivel and a push plate. The rotation of the swivel on the rotating groove drives the push plate to move in the groove, realizes the extrusion of the material, and squeezes the material from the rotating groove to fill the gap, thereby ensuring the connection stability and reliability between the manhole cover support seat and the installation step. The combined design of the rotating groove and the extrusion element is used to deal with the small gap that may exist between the installation step and the connecting and mounting part. The material (usually asphalt, filler, etc.) is introduced through the material inlet of the rotating groove and is evenly and tightly squeezed into the gap under the action of the extrusion element. The flexible rotation of the swivel on the rotating groove, combined with the extended design of the push plate, enables the material to be effectively pushed along the path of the rotating groove until it is squeezed out from the material outlet, completing the sealing and filling of the gap. It is not only easy to operate, but also greatly improves the sealing efficiency and quality, effectively avoiding leakage problems caused by unsealed gaps.

[0016] The assembly method of the manhole cover support seat, first, in step S1, the pit construction and the preparation of the installation wellhead are the basic links. By accurately planning the position of the manhole cover and using mud and sand concrete to prepare the installation wellhead on the building carrier, the accuracy of the manhole cover position and the stability of the wellhead structure are ensured. This step provides a solid foundation for the subsequent assembly of the manhole cover support seat, and also ensures the smooth progress of the entire installation process. In step S2, assembling the manhole cover support seat is a key step. After waiting for the installation wellhead to solidify, the manhole cover support seat is placed on the wellhead for assembly. This step ensures the close combination of the manhole cover support seat and the installation wellhead, avoiding the loosening or displacement problems that may occur during subsequent use. At the same time, the design of the manhole cover support seat also fully considers the load-bearing and stability requirements, ensuring the safety and reliability of the manhole cover in long-term use. Steps S3 and S4 involve the injection and extrusion of asphalt materials. After the assembly of the manhole cover support seat is completed, the asphalt material is injected through the rotating trough, and the asphalt material is extruded using the extrusion element and the push plate to fill the gap between the installation step and the connecting installation part. This step not only achieves the complete filling of the gap, but also effectively prevents moisture, debris, etc. from entering the inside of the manhole cover through the sealing of asphalt, thereby extending the service life of the manhole cover. At the same time, the extrusion process of asphalt also ensures the uniformity and tightness of the filler, and improves the stability and load-bearing capacity of the manhole cover. In step S5, the curing of asphalt is the final link. After waiting for the asphalt to be completely cured, the extrusion element is removed from the rotating groove, and the upper surface of the rotating groove and the fixed outer ring is covered with silt concrete. This step not only makes the manhole cover support seat more firmly buried at the installation wellhead, but also further enhances the impact resistance and durability of the manhole cover through the covering of silt concrete. At the same time, the covering of silt concrete also has additional effects such as beautifying the environment and reducing noise. The present invention realizes efficient, stable and durable installation of the manhole cover through a series of steps such as precise planning, stable assembly, asphalt filling and extrusion, and curing and covering. This method not only improves the installation quality and efficiency of the manhole cover, but also ensures the safety and reliability of the manhole cover in long-term use.

DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Figure 1 to Figure 7As shown, in one embodiment of the present invention, a manhole cover support seat assembly mechanism is involved, including a building carrier 1, a manhole cover support seat 2 and an extrusion element 3, the building carrier 1 is provided with a mounting wellhead 4, the mounting wellhead 4 is provided with a mounting step 41, the manhole cover support seat 2 includes an assembly positioning ring 21, a connecting mounting portion 22 and a fixed outer ring 23, one side of the connecting mounting portion 22 abuts against the mounting step 41, the assembly positioning ring 21 is used to cooperate with the bottom of the mounting wellhead 4, and the fixed outer ring 23 is in At the port where the wellhead 4 is installed, the connecting and installing part 22 is provided with a rotating groove 221, and the rotating groove 221 is provided with a material outlet 222, one end of the material outlet 222 is connected to the installation step 41, and the extruding element 3 includes a rotating ring 31 and a push plate 32, the rotating ring 31 is rotatably arranged on the rotating groove 221, and the push plate 32 extends into the rotating groove 221, and the rotating ring 31 is used to drive the push plate 32 to rotate in the rotating groove 221, so as to squeeze the material in the rotating groove 221 out of the material outlet 222. In this embodiment, the installation stability and load-bearing capacity of the wellhead support 2 are effectively improved by the precise matching of the wellhead 4 installed by the wellhead support 2 and the building carrier 1, especially the close fit between the assembly positioning ring 21 and the bottom of the wellhead 4, and the design that the connecting and installing part 22 abuts against the installation step 41. This design not only ensures the safety of the wellhead in daily use, but also effectively resists the influence of external environmental factors (such as wind and rain erosion, vehicle rolling, etc.) on the structural integrity of the wellhead. The design of the rotating groove 221 and the extrusion element 3 greatly simplifies the installation process of the manhole cover support seat 2. The extrusion element 3 includes a swivel 31 and a push plate 32. The rotation of the swivel 31 on the rotating groove 221 drives the push plate 32 to move in the groove, thereby realizing the extrusion of the material, extruding the material from the rotating groove 221 to fill the gap, thereby ensuring the stability and reliability of the connection between the manhole cover support seat 2 and the installation step 41. The combined design of the rotating groove 221 and the extrusion element 3 is used to deal with the small gap that may exist between the installation step 41 and the connecting installation part 22. The material (usually asphalt, filler, etc.) is introduced through the material inlet of the rotating groove 221 and is evenly and tightly squeezed into the gap under the action of the extrusion element 3. Among them, the flexible rotation of the swivel 31 on the rotating groove 221, combined with the extended design of the push plate 32, enables the material to be effectively pushed along the path of the rotating groove 221 until it is extruded from the material outlet 222 to complete the sealing filling of the gap. It is not only easy to operate, but also greatly improves the sealing efficiency and quality, effectively avoiding leakage problems caused by unsealed gaps.

[0022] The building carrier 1 is provided with a reinforcement part 11 on the periphery of the installation wellhead 4, and the reinforcement part 11 is made of concrete mud. Specifically, the opposite surface of the installation step 41 and the material outlet 222 is provided with a rough surface 411. In this embodiment, the provision of the reinforcement part 11 greatly enhances the structural stability of the installation wellhead 4. As a high-strength and high-durability material, concrete mud can effectively resist the erosion of external loads and environmental factors, thereby ensuring the safety and reliability of the wellhead during long-term use. The rough surface 411 provided on the opposite surface of the installation step 41 and the material outlet 222 further improves the firmness of the assembly. The rough surface 411 increases the friction of the contact surface, so that the manhole cover support seat 2 can be more closely combined with the wellhead during installation, avoiding safety hazards caused by looseness. Especially when the filler is filled, the filling contact area is larger and the stability is better.

[0023] A positioning metal ring 412 is provided on the lower side of the installation step 41, and the positioning metal ring 412 is used to position the assembly positioning ring 21. In this embodiment, the introduction of the positioning metal ring 412 greatly improves the assembly efficiency. During the assembly process of the manhole cover support seat 2, the positioning ring can quickly and accurately dock with the positioning metal ring 412, avoiding the position deviation that may exist in the traditional assembly method, thereby shortening the assembly time and reducing labor intensity. Secondly, the close combination of the positioning metal ring 412 and the installation step 41 not only provides a stable support for the positioning ring, but also effectively disperses the pressure of the manhole cover and vehicle load on the support seat, thereby extending the service life.

[0024] A support platform 24 is provided on the inner periphery of the connecting mounting portion 22 of the manhole cover support seat 2, and the support platform 24 is used to place the manhole cover. Specifically, a separation ring 25 is provided between the support platform 24 and the rotating groove 221. In this embodiment, the separation ring 25 effectively isolates the space between the support platform 24 and the rotating groove 221, preventing the manhole cover from being displaced or shaken during installation or use, thereby further improving the stability of the overall structure. At the same time, the separation ring 25 also serves as a barrier to reduce the erosion of the internal structure of the manhole cover support seat 2 by external environmental factors and extend its service life. In addition, the coordinated use of the support platform 24 and the separation ring 25 also optimizes the force distribution of the manhole cover support seat 2, making the structure more balanced when bearing the weight of the manhole cover and external loads, and reducing the risk of damage caused by stress concentration.

[0025] The outer periphery of the swivel 31 is provided with a rotating tooth 311, and a driving groove 223 is provided on one side of the connecting and mounting portion 22. A driving gear 224 is provided on the driving groove 223, and the driving gear 224 is meshed with the rotating tooth 311 to drive the swivel 31 to rotate in the rotating groove 221. In this embodiment, the rotating teeth 311 provided on the outer periphery of the swivel 31 form a precise meshing with the driving gear 224 in the driving groove 223, and this structure ensures the accurate transmission of the driving force. When the driving source acts on the driving gear 224, the swivel 31 can be driven to rotate in the rotating groove 221 smoothly and efficiently through the close fit between the teeth. This design not only improves the operating efficiency of the assembly mechanism of the manhole cover support seat 2, but also effectively reduces the energy loss caused by friction and wear. In addition, the meshing mode of the driving groove 223 and the driving gear 224 also has high stability and reliability. During the assembly process of the manhole cover support 2, even in the face of large external interference or vibration, the structure can maintain a stable driving effect, thereby ensuring the correct assembly and firm locking of the manhole cover support 2.

[0026] like Figure 1 to Figure 7 As shown, a method for assembling a manhole cover support seat includes the manhole cover support seat 2 assembly mechanism; the assembly method includes the following steps: step S1, pit digging construction: planning the location where the manhole cover needs to be constructed, and then preparing the installation wellhead 4 on the building carrier 1 through mud and sand concrete; step S2, assembling the manhole cover support seat 2: waiting for the installation wellhead 4 on the building carrier 1 to solidify, and after solidification, placing the manhole cover support seat 2 on the installation wellhead 4 for assembly; step S3, injecting asphalt material: after completing the assembly of the manhole cover support seat 2, injecting asphalt material into the rotating groove 221, and the asphalt material is discharged from the material outlet 222 to align the installation step 41 with the connecting installation step 41. Fill the gap between the mounting parts 22; Step S4, asphalt extrusion: after the gap filling is completed, the extrusion element 3 is installed on the rotating groove 221, and the rotating ring 31 is rotated to drive the push plate 32 to rotate on the rotating groove 221, so as to extrude the asphalt material in the rotating groove 221, and further seal and fill the gap between the installation step 41 and the connecting mounting part 22, and block the material outlet 222 by the push plate 32; Step S5, asphalt curing: after waiting for the asphalt to solidify, the extrusion element 3 is removed from the rotating groove 221, and the upper surface of the rotating groove 221 and the fixed outer ring 23 is covered with mud and sand concrete, so that the manhole cover support seat 2 is buried in the installation wellhead 4.

[0027] In step S1 of the present embodiment, the preparation of pit digging and installation of the wellhead 4 is the basic link. By accurately planning the position of the manhole cover and using mud and sand concrete to prepare the installation wellhead 4 on the building carrier 1, the accuracy of the manhole cover position and the stability of the wellhead structure are ensured. This step provides a solid foundation for the subsequent assembly of the manhole cover support seat 2, and also ensures the smooth progress of the entire installation process. In step S2, assembling the manhole cover support seat 2 is a key step. After waiting for the installation wellhead 4 to solidify, the manhole cover support seat 2 is placed on the wellhead for assembly. This step ensures the close combination of the manhole cover support seat 2 and the installation wellhead 4, avoiding the loosening or displacement problems that may occur during subsequent use. At the same time, the design of the manhole cover support seat 2 also fully considers the load-bearing and stability requirements, ensuring the safety and reliability of the manhole cover in long-term use. Steps S3 and S4 involve the injection and extrusion of asphalt materials. After the assembly of the manhole cover support seat 2 is completed, asphalt material is injected through the rotating groove 221, and the asphalt material is squeezed out by the extrusion element 3 and the push plate 32 to fill the gap between the installation step 41 and the connecting installation part 22. This step not only realizes the complete filling of the gap, but also effectively prevents moisture, debris, etc. from entering the inside of the manhole cover through the sealing of the asphalt, thereby extending the service life of the manhole cover. At the same time, the extrusion process of asphalt also ensures the uniformity and tightness of the filler, and improves the stability and load-bearing capacity of the manhole cover. In step S5, the curing of asphalt is the final link. After waiting for the asphalt to be completely cured, the extrusion element 3 is removed from the rotating groove 221, and the upper surface of the rotating groove 221 and the fixed outer ring 23 is covered with silt concrete. This step not only makes the manhole cover support seat 2 more firmly buried at the installation wellhead 4, but also further enhances the impact resistance and durability of the manhole cover through the covering of silt concrete. At the same time, the covering of silt concrete also has additional effects such as beautifying the environment and reducing noise. The present invention realizes efficient, stable and durable installation of manhole covers through a series of steps including precise planning, stable assembly, asphalt filling and extrusion, and solidification covering. This method not only improves the installation quality and efficiency of manhole covers, but also ensures the safety and reliability of manhole covers in long-term use.

[0028] In step S1, when preparing and installing the wellhead 4, a rough gravel surface is reserved on the wall surface of the installation step 41. In this embodiment, the rough gravel surface is used for more sufficient filling and connection during asphalt filling, with better stability, better connection strength, and more stable seismic strength.

[0029] In step S3, liquid asphalt is poured on the rotating groove 221, and the gap between the installation step 41 and the connecting and mounting portion 22 is filled by the liquid asphalt flowing on the rotating groove 221. In the present embodiment, liquid asphalt manhole cover. In the present embodiment, the fluidity of the liquid asphalt is excellent, and it can quickly and evenly cover various areas on the rotating groove 221, especially for the small gap between the installation step 41 and the connecting and mounting portion 22, the liquid asphalt can penetrate and fill, thereby effectively improving the sealing of the assembly. This feature is very important for preventing the leakage of liquids such as rainwater and sewage, and ensures the stable operation of the manhole cover support seat 2 and the system in which it is located. Secondly, through the rotation of the rotating groove 221, the liquid asphalt can be further compacted and evenly distributed during the flow process, which enhances the compactness and firmness of the filling. This dynamic filling method is more efficient than static filling, and can reduce potential defects caused by uneven filling.

[0030] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
