Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, and in particular to a noise-preventing sealing device for municipal road manhole covers. Background Technology

[0002] With the continuous development of technology, urban construction has increased, with infrastructure being particularly important. Some drainage facilities and other pipelines are laid underground, reducing the number of external pipelines in the city and avoiding the safety issues associated with overhead power lines. However, some pipelines still require regular maintenance, necessitating the construction of manholes at designated locations to facilitate subsequent maintenance of the facilities within the pipelines. When maintenance is not required, manhole covers are installed at the manholes to prevent debris and personnel from falling in. This is a crucial part of municipal construction.

[0003] Manhole covers are often installed close to roads, causing vehicles to frequently come into contact with them. Since the manhole covers are designed for hard contact installation, they vibrate, causing loud noises. In addition, the frequent vibrations can cause the manhole covers to loosen, and in severe cases, they may bounce up and become misaligned, leading to unnecessary safety hazards.

[0011] This utility model provides a noise-preventing sealing device for municipal road manhole covers, which has the following beneficial effects:

[0012] In this invention, a sealing component is directly added to the location where the manhole cover assembly is installed on the pipeline well. The sealing component is made of rubber and features an arc-shaped contact strip. The contact strip helps to increase the seal after contact and prevents debris from accumulating at the contact strip, thus eliminating noise from the overall placement of the manhole cover assembly and providing stable cushioning. The support component is designed to snap onto the pipeline well, and a collection component can be installed at the bottom of the support component to help prevent debris from falling. A buffer component is installed near the pipeline well on the support component, and a leaf spring is added at the installation position of the buffer component. A contact frame is installed on the bottom surface of the manhole cover assembly, and the contact frame directly contacts the buffer component, allowing the buffer component to provide auxiliary cushioning for the manhole cover assembly, making the manhole cover assembly more stable. The entire support component can be quickly assembled and disassembled, increasing the ease of use of the device.

[0013] Furthermore, to make the manhole cover assembly more stable under impact, a base frame ring is directly installed on the top of the manhole. The support ring between the base frame ring and the manhole provides stability to the base frame ring. When the manhole cover assembly is closed, the top frame ring of the manhole cover assembly contacts the base frame ring, achieving overall cushioning of the manhole cover assembly by the sealing assembly. A contact strip is provided on the contact surface between the base frame ring and the top frame ring, and the contact strip is made into an arc shape, so that the sealing assembly can increase the sealing performance through the contact strip. After the sealing assembly is opened, the arc structure of the contact strip avoids the presence of some debris.

[0014] Furthermore, the bottom of the support frame is designed to be raised to avoid contact between the reinforcing ribs at the bottom of the manhole cover assembly and the support assembly. The limiting block structure on the support frame helps to stabilize the overall installation of the support assembly. A guide groove is provided at the top of the support frame to facilitate the subsequent sliding installation of the buffer assembly.

[0015] In addition, the top slide is directly slidably installed on top of the support assembly, while the bottom plate is hinged to the bottom of the top slide. The end of the bottom plate is directly fixed with bolts, so that the top slide can slide stably. Two sets of leaf springs are set at the outer end of the top slide, and side guide wheels are installed on the top slide, so that the side guide wheels can contact the contact frame. When the manhole cover assembly vibrates and descends, the contact frame will contact the side guide wheels to test the pressure of the buffer assembly, thereby achieving the stable buffering effect of the buffer assembly.

[0016] In addition, to avoid the discharge of some debris, the connecting column is directly connected to the support component. A spring frame is installed on the top of the connecting column, so that the collection component can slide on the support component, giving the collection component a buffering effect. The collection rack at the bottom of the connecting column can catch debris, and the side wall wheel on the outer end face of the collection rack assists in sliding in the pipe well.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1: Please refer to Figures 1 to 6 :

[0035] This utility model proposes a noise-proof sealing device for manhole covers on municipal roads, comprising: a pipe well 1; a manhole cover assembly 2 is hingedly installed at the top of the pipe well 1; a sealing assembly 3 is installed between the pipe well 1 and the manhole cover assembly 2; a support assembly 4 is installed at the upper end of the pipe well 1; a collecting assembly 6 is installed at the bottom of the support assembly 4; and a buffer assembly 5 is installed near the pipe well 1 where the support assembly 4 is located, with the top of the buffer assembly 5 contacting the bottom of the manhole cover assembly 2.

[0036] Among them, such as Figure 2 Figure 5 As shown, the manhole cover plate 201 of the manhole cover assembly 2 is hinged to the top of the pipe well 1. The bottom surface of the manhole cover plate 201 is provided with bolt posts 202 extending downwards. A contact frame 203 is installed at the bolt posts 202 of the manhole cover plate 201. The corresponding bolt post 202 of the contact frame 203 is set with a slotted structure. When the device is in use, the bolt post 202 of the manhole cover plate 201 needs to be installed with the contact frame 203 so that when the manhole cover assembly 2 is closed as a whole, the contact frame 203 contacts the buffer assembly 5, thereby realizing the overall buffering of the manhole cover assembly 2. The slotted structure at the corresponding bolt post 202 of the contact frame 203 allows the position of the contact frame 203 to be adjusted in the manhole cover plate 201.

[0037] Among them, such as Figure 2 Figure 4 As shown, the support ring 301 of the sealing component 3 is installed on the top of the manhole cover component 2, corresponding to the top of the manhole 1. The bottom of the support ring 301 has a protrusion, and the upper end of the support ring 301 is a base ring 302. The top ring 303 of the sealing component 3 is fixed to the bottom surface of the manhole cover component 2. Contact strips 304 are provided on the contact surfaces of the top ring 303 and the base ring 302. The contact strips 304 are arc-shaped. To make the manhole cover component 2 more stable under impact, the base ring 302 is directly installed on the top of the manhole 1. The base ring 302 and the manhole cover... The support ring 301 between the two rings has the function of increasing the stability of the base ring 302. When the manhole cover assembly 2 is closed, the top ring 303 of the manhole cover assembly 2 will contact the base ring 302, realizing the overall buffer of the manhole cover assembly 2 by the sealing assembly 3. The contact surface between the base ring 302 and the top ring 303 is provided with a contact strip 304, and the contact strip 304 is set in an arc shape, so that the sealing assembly 3 can increase the sealing performance through the contact strip 304. After the sealing assembly 3 is opened, the arc structure of the contact strip 304 avoids the presence of some debris.

[0038] Among them, such as Figure 3 Figure 5 As shown, the support frame 401 of the support component 4 is configured as a frame-like structure. The bottom of the support frame 401 is convex, and the end of the support frame 401 is snapped onto the pipe well 1. A limiting block 402 is installed near the pipe well 1 on the support frame 401. A guide groove 403 is provided on the support frame 401. Firstly, the overall bottom of the support frame 401 is convex to avoid contact between the bottom reinforcing rib of the manhole cover component 2 and the support component 4. The limiting block 402 structure on the support frame 401 helps to make the overall installation of the support component 4 more stable. The guide groove 403 on the top of the support frame 401 facilitates the subsequent sliding installation of the buffer component 5.

[0039] Among them, such as Figure 3 Figure 6 As shown, the top slide 501 of the buffer assembly 5 is slidably mounted on the top of the support assembly 4. A bottom clamping plate 502 is hinged to the bottom of the top slide 501, and the end of the bottom clamping plate 502 is fastened with bolts, directly sliding the top slide 501 onto the top of the support assembly 4. The bottom clamping plate 502 is hinged to the bottom of the top slide 501, and the end of the bottom clamping plate 502 is directly fixed with bolts, enabling the top slide 501 to slide stably. Two sets of leaf springs 50 are installed on the outward-facing end of the bottom clamping plate 502. 4. A side guide wheel 503 is rotatably installed at the upper outer end of the top slide 501. The side guide wheel 503 directly contacts the contact frame 203 of the manhole cover assembly 2. Two sets of leaf springs 504 are set at the outer end of the top slide 501, and the side guide wheel 503 is installed on the top slide 501, so that the side guide wheel 503 can contact the contact frame 203. When the manhole cover assembly 2 vibrates and descends, the contact frame 203 will contact the side guide wheel 503 to test the pressure of the buffer assembly 5, thereby achieving the stable buffering effect of the buffer assembly 5.

[0040] Among them, such as Figure 2 Figure 3 As shown, the connecting column 601 of the collecting component 6 is adjusted and installed in the middle position of the support component 4. A spring frame 602 is installed between the top of the connecting column 601 and the support component 4. A collecting frame 603 is set at the bottom of the connecting column 601. The collecting frame 603 is set in a mesh frame shape. Side wall wheels 604 are rotatably installed on the edge of the collecting frame 603. In order to avoid some debris from falling out, the connecting column 601 is directly sleeved on the support component 4. The spring frame 602 is installed on the top of the connecting column 601 so that the collecting component 6 can slide on the support component 4, so that the collecting component 6 has a buffering effect. The collecting frame 603 at the bottom of the connecting column 601 can catch debris. The side wall wheel 604 on the outer end face of the collecting frame 603 assists in sliding in the pipe well 1.

[0041] The working principle of this embodiment is as follows: During installation, the collecting component 6 is first installed at the bottom of the support component 4. The collecting component 6 is manually pressed to check whether it is stable under the support component 4. Then, the collecting component 6 is first guided into the position of the pipe well 1, so that the support component 4 at the top is snapped into the upper part of the pipe well 1. The buffer component 5 is slidably installed at the snapping position of the support component 4. At the same time, the contact frame 203 is installed at the bottom of the manhole cover component 2. The contact frame 203 is positioned at the support component 4 so that after the manhole cover component 2 is closed, the contact frame 203 contacts the buffer component 5, forming a buffering effect on the manhole cover component 2.

[0042] The support ring 301 of the sealing component 3 is directly installed on the top of the pipe well 1. The base frame ring 302 is installed on the support ring 301. The top frame ring 303 of the sealing component 3 is fixed to the bottom of the manhole cover component 2. After the manhole cover component 2 is closed as a whole, the base frame ring 302 and the top frame ring 303 are in contact with each other.
