Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to a road and bridge pavement maintenance device. Background Technology

[0002] Roads and bridges play an extremely important role in modern society. They are core components of transportation infrastructure and have a profound impact on economic development, social communication, regional connectivity, and emergency rescue. During use, road and bridge surfaces can be damaged due to vehicle overloading or natural factors, thus requiring regular maintenance to ensure the load-bearing capacity and effectiveness of the bridges.

[0003] When bridge pavement is damaged, potholes or craters will appear on the surface, obstructing passing vehicles. The potholes are exposed to the outside, allowing a large amount of impurities or gravel to enter. Because the inner wall of the pothole is uneven when it is damaged, it is difficult to clean the impurities inside the pothole. As a result, the repair material cannot fully bond with the inner wall of the pothole after being poured, which reduces the quality of the repair and affects the performance of the pavement after repair. Utility Model Content

[0004] The purpose of this utility model is to provide a road and bridge pavement maintenance device to solve the problem mentioned in the background art that when repairing potholes on bridge pavements, the complex internal structure of the potholes makes it difficult to completely clean the impurities and gravel inside, resulting in the inability of the filling repair material to fully bond with the pothole, thus reducing the repair effect and affecting the pavement performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road and bridge pavement maintenance device, including a support base, an installation frame at the bottom of the support base, a cleaning component for cleaning impurities in road surface potholes inside the installation frame, the cleaning component including a motor at the top of the support base, a lead screw at the output end of the motor, a collar outside the lead screw, and a connecting screw and a connecting rod inside the collar;

[0006] The bottom of the collar is provided with a connecting tube, one end of which is provided with a positioning hole and the other end is provided with an air bladder. The air bladder is provided with a soft rubber layer on the outside and an air supply pipe is provided inside the mounting frame.

[0007] Preferably, the mounting frame is located at the bottom of the support base and is connected to the support base by bolts. The motor is connected to the top of the support base by bolts. The output end of the motor is connected to the lead screw through a coupling, and the other end extends into the mounting frame.

[0008] Preferably, the mounting frame has a hollow structure inside, the collar is sleeved on the outside of the lead screw, and the texture of the outer wall of the lead screw corresponds to the inner wall of the collar. One end of the connecting rod is connected to the inner wall of the mounting frame by bolts.

[0009] Preferably, both the connecting screw and the connecting rod pass through the collar and extend into the positioning hole at the top of the connecting tube, and the connecting screw is screwed into the inner wall of the positioning hole to connect the collar to the connecting tube.

[0010] Preferably, one end of the connecting tube is connected to the airbag, the inside of the airbag is in a closed state, the soft rubber layer is wrapped around the outside of the airbag and connected to the outer wall of the airbag, the outer wall of the soft rubber layer has a hollow structure and is provided with multiple holes, and the inside of the holes of the soft rubber layer is coated with an adhesive coating.

[0011] Preferably, one end of the air supply pipe is connected to the air supply end of the air pump, and the other end extends into the mounting frame, slides against the inner wall of the mounting frame, penetrates the airbag, and extends into the interior of the airbag.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The mounting frame can be suspended inside the pit using the support base. When the motor rotates with the lead screw, the texture on the outer wall drives the collar to slide within the mounting frame, thereby causing the connecting pipe to slide out of the mounting frame and extend into the pit. This places the airbag outside the connecting pipe in the pit, and gas is injected into the airbag through the air supply pipe, causing the airbag to inflate and support the soft rubber layer so that it adheres to the inner wall of the pit. Impurities or gravel in the pit enter through the perforations on the outer wall of the soft rubber layer, and the adhesive coating on the inner wall of the perforations adheres to the impurities, collecting them from the pit. The airbag ensures a full fit with the inner wall of the pit, thereby improving the cleaning effect of the pit's inner wall, reducing impurity residue, and ensuring the quality of the repair material for the pit repair.

[0014] 2. The connecting screws between the collar and the connecting tube allow for flexible installation and removal of the connecting tube and the collar. This facilitates replacement when the soft rubber layer is used to absorb impurities, improving the efficiency of impurity cleaning. Furthermore, disassembly makes it easier to clean impurities on the airbag and the soft rubber layer, ensuring multiple uses and guaranteeing the effectiveness of the product.

[0015] This invention utilizes an inflatable airbag to ensure it fully adheres to the inner wall of the pothole. The soft rubber layer with perforated holes on the outside of the airbag absorbs impurities within the pothole during inflation, improving the cleaning effect and ensuring the quality of adhesion between the repair material and the pothole, thereby enhancing the performance of the repaired road surface.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0024] Please see the appendix Figure 1-3 As shown, a road and bridge pavement maintenance device includes a support base 1. A mounting frame 3 is provided at the bottom of the support base 1. The mounting frame 3 can store the airbag 6 and the soft rubber layer 7. Inside the mounting frame 3 is a cleaning component for cleaning impurities in road surface potholes. The cleaning component includes a motor 2 located at the top of the support base 1. When energized, the motor 2 drives a lead screw 201 to rotate. The output end of the motor 2 is provided with the lead screw 201. The outer wall texture of the lead screw 201 corresponds to the inner wall of the collar 4, so that when the lead screw 201 rotates, it can drive the collar 4 to rise and fall on the lead screw 201. A collar 4 is provided outside the lead screw 201. The collar 4 can be connected to a connecting pipe 5 via a connecting screw 401, facilitating disassembly and replacement of the airbag 6 after use. Inside the collar 4 are a connecting screw 401 and a connecting rod 402. The connecting rod 402 passes through the collar 4, thus limiting the angle of the collar 4 when the lead screw 201 drives the collar 4 to rise and fall.

[0025] Mounting frame 3 is located at the bottom of support base 1 and is connected to support base 1 by bolts. Motor 2 is connected to the top of support base 1 by bolts. The output end of motor 2 is connected to lead screw 201 by coupling, and the other end extends into mounting frame 3. The interior of mounting frame 3 is a hollow structure. Collar 4 is fitted on the outside of lead screw 201, and the texture of the outer wall of lead screw 201 corresponds to the inner wall of collar 4. One end of connecting rod 402 is connected to the inner wall of mounting frame 3 by bolts.

[0026] In this embodiment: when cleaning the pit, the support base 1 can be installed around the pit, so that the mounting frame 3 is suspended inside the pit. When the motor 2 is powered on, the lead screw 201 rotates and, in conjunction with the texture, the collar 4 extends outward inside the mounting frame 3, and drives the connecting pipe 5 and the airbag 6 to extend into the pit.

[0027] Furthermore, after the airbag 6 has been used to clean the pits, the collar 4 and the connecting tube 5 can be disassembled by rotating the connecting screw 401, and a new connecting tube 5 and airbag 6 can be quickly replaced, which facilitates the replacement of airbag 6. Especially when cleaning multiple pits, the airbag 6 can be quickly replaced to ensure cleaning efficiency.

[0028] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 2-5 The bottom of the collar 4 is provided with a connecting tube 5, which is a through structure to facilitate sliding of the collar 4 on the lead screw 201. When the lead screw 201 passes through the connecting tube 5 and abuts against the airbag 6, the airbag 6 is not affected by the abutment of the lead screw 201 because it is made of flexible material. One end of the connecting tube 5 is provided with a positioning hole 501 for positioning the collar 4 when it is connected to the connecting tube 5, and the other end is provided with an airbag 6. The airbag 6 is provided with a soft rubber layer 7. The soft rubber layer 7 is made of flexible material, so when the airbag 6 expands together with it, the hollow holes on the outside of the soft rubber layer 7 will deform and expand accordingly. This allows impurities to enter the hollow holes on the outer wall of the soft rubber layer 7 when it is in contact with the inner wall of the pit. The impurities are adsorbed and captured by the adhesive coating on the inner wall of the holes, thereby cleaning the inside of the pit. The mounting frame 3 is provided with an air supply pipe 8. One end of the air supply pipe 8 is connected to an air pump to extend and deliver gas into the airbag 6, thereby inflating the airbag 6 and supporting it to fit against the inner wall of the pit.

[0029] Both the connecting screw 401 and the connecting rod 402 pass through the collar 4 and extend into the positioning hole 501 at the top of the connecting tube 5. The connecting screw 401 is screwed into the inner wall of the positioning hole 501 to connect the collar 4 and the connecting tube 5. One end of the connecting tube 5 is connected to the airbag 6. The airbag 6 is closed inside. The soft rubber layer 7 is wrapped around the outside of the airbag 6 and connected to the outer wall of the airbag 6. The outer wall of the soft rubber layer 7 has a hollow structure and multiple holes. The holes of the soft rubber layer 7 are coated with an adhesive coating. One end of the air supply tube 8 is connected to the air supply end of the air pump, and the other end extends into the mounting frame 3, slides against the inner wall of the mounting frame 3, passes through the airbag 6, and extends into the airbag 6.

[0030] In this embodiment: when the airbag 6 is placed in the pit, the air pump connected to the other end of the air supply pipe 8 injects gas into the airbag 6 through the air supply pipe 8 (the air supply pipe 8 is a telescopic structure and can move with the connecting pipe 5), causing the airbag 6 to expand and support the soft rubber layer 7, which expands together and adheres to the inner wall of the pit. As the soft rubber layer 7 expands, the perforated holes on the outer wall enlarge, allowing impurities or gravel from the inner wall of the pit to roll into the perforated holes. The adhesive coating on the inner wall of the perforated holes helps to capture the impurities, thus cleaning the pit. After cleaning, the gas in the airbag 6 is extracted, causing it to contract. During contraction, the impurities are sealed in the perforated holes of the soft rubber layer 7 as required by the hole diameter, improving the cleaning effect of the impurities in the pit and ensuring that the repair material can fully bond with the pit, thus ensuring the quality of the repair.

[0031] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
