Description

Technical Field

[0001] This utility model relates to the field of road surface repair technology, and in particular to a rapid repair device for municipal road and bridge pavements. Background Technology

[0002] In recent years, many highways, after their completion, have experienced widespread early-stage damage due to factors such as rapid traffic growth, larger vehicles, severe overloading, channelized traffic, and the performance of asphalt materials and the quality of pavement construction. Some of these damages are quite severe, requiring extensive pothole repairs within one or two years of opening. It can be predicted that, with the increase in highway mileage and the extension of service life, the focus of highway construction in my country will shift from primarily construction to a combination of construction and maintenance, with a primary emphasis on maintenance.

[0003] Current traditional repair methods cannot achieve the telescopic function of pressure rollers, resulting in a large distance between operators and the ground during road repair. The dust and fumes generated are easily inhaled by workers, affecting their health. At the same time, existing methods lack anti-splash function during road rolling, making operators vulnerable to being hit by gravel or debris on the road surface, posing a safety hazard. Existing pressure rollers do not have a heating function or a buffer mechanism to prevent heat generation, resulting in low efficiency during road repair and the risk of structural damage due to road bumps. To address the above problems, this paper provides a rapid repair device for municipal road and bridge pavements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rapid repair device for municipal road and bridge pavements, which aims to improve the problems of traditional pavement repair methods that cannot control the distance between the pressure roller and the operator, and lack anti-splash function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid repair device for municipal road and bridge pavement, comprising a base plate and a pressure roller, wherein a base is installed at the top center of the base plate, a drive motor is fixedly installed through one side of the base plate, a plurality of heating plates are installed inside the pressure roller, buffer devices are provided on the surface and both ends of the heating plates, anti-splash mechanisms are provided on both sides and the front end of the pressure roller, a handle is installed at the back center of the base plate, and casters are installed around the bottom of the base plate.

[0006] As a further description of the above technical solution:

[0007] The buffer device includes several buffer springs connected to the heating plate. One end of each buffer spring is connected to a buffer plate, and both ends of the buffer plate extend to both sides of the heating plate and are connected to sleeves. Damping rods are installed between the sleeves.

[0008] As a further description of the above technical solution:

[0009] The anti-splash mechanism includes an inflatable sealing skirt installed at the front end of the pressure roller. Both ends of the inflatable sealing skirt are connected to an inflatable plate. The inflatable plate is connected to an inflation port at the connection point of the inflatable sealing skirt. An upright plate is fixedly connected to the inner side of the inflatable plate by external bolts. A top column is fixedly connected to the inner side of the upright plate.

[0010] As a further description of the above technical solution:

[0011] The top column is equipped with a quick-release mechanism at its back end, and the top column is connected to a hydraulic cylinder through the quick-release mechanism.

[0012] As a further description of the above technical solution:

[0013] The quick-release mechanism includes an insert block fixed to the back end of the top column, side blocks on both sides of the insert block, and two locking blocks fixedly installed inside the insert block at one end of the hydraulic cylinder. The side blocks are threaded through the insert block and screwed to the side blocks with locking bolts, and the locking bolts are screwed to the locking blocks for fixation.

[0014] As a further description of the above technical solution:

[0015] One end of the drive motor is mounted with a swing device through the inner side of the base. The top two sides of the swing device are fixedly connected to connecting plates that are movably disposed on the inner side of the base. U-shaped seats are fixedly installed between the inner sides of the connecting plates.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, a drive motor drives a swinging device to rotate, which in turn drives a connecting plate to rotate. The connecting plate then causes the hydraulic cylinder inside the U-shaped seat to shift at an angle, thereby causing the pressure roller to contact the ground. During road repair, the inflatable sealing skirt can be inflated through the air inlet, effectively preventing flying debris from affecting the safety of workers. A quick-release mechanism allows for rapid disassembly and repair of the hydraulic cylinder and repair components. A buffer device effectively mitigates damage to internal parts caused by road bumps when the heating plate is heating, thus improving service life. Attached Figure Description

[0024] 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.

[0025] Reference Figure 1-4 An embodiment of this utility model provides a rapid repair device for municipal road and bridge pavement, including a base plate 1 and a pressure roller 4. A base 2 is installed at the top center of the base plate 1, and a drive motor 3 is fixedly installed through one side of the base 2. Several heating plates 5 are installed inside the pressure roller 4. Buffer devices 6 are provided on the surface and both ends of the heating plates 5. Anti-splash mechanism 7 is provided on both sides and the front end of the pressure roller 4. A handle 13 is installed at the back center of the base plate 1, and casters 14 are installed around the bottom of the base plate 1.

[0026] The buffer device 6 includes several buffer springs 61 connected to the heating plate 5. One end of the buffer spring 61 is connected to a buffer plate 62. Both ends of the buffer plate 62 extend to both sides of the heating plate 5 and are connected to sleeves 63. Damping rods 64 are installed between the sleeves 63.

[0027] The anti-splash mechanism 7 includes an inflatable sealing skirt 71 installed at the front end of the pressure roller 4. Both ends of the inflatable sealing skirt 71 are connected to an inflatable plate 72. The inflatable plate 72 is connected to an air inlet 73 at the connection point of the inflatable sealing skirt 71. An upright plate 74 is fixedly connected to the inner side of the inflatable plate 72 by external bolts. A top column 75 is fixedly connected to the inner side of the upright plate 74.

[0028] The top post 75 is equipped with a quick-release mechanism 8 at its rear end, and the top post 75 is connected to a hydraulic cylinder 9 through the quick-release mechanism 8.

[0029] The quick-release mechanism 8 includes an insert block 81 fixed to the back end of the top column 75. Side blocks 82 are provided on both sides of the insert block 81. One end of the hydraulic cylinder 9 is inserted into the interior of the insert block 81 and two locking blocks 83 are fixedly installed. The side blocks 82 pass through the insert block 81 and are screwed together with locking bolts 84. The locking bolts 84 are screwed together with the locking blocks 83.

[0030] One end of the drive motor 3 passes through the inner side of the base 2 and is equipped with a swing device 10. The top two sides of the swing device 10 are fixedly connected with connecting plates 11 that are movably set on the inner side of the base 2. U-shaped seats 12 are fixedly installed on the inner sides of the connecting plates 11.

[0031] Specifically, the base plate 1 serves as the supporting bottom structure of the overall structure, while the base 2 acts as the adjustment and supporting structure. Starting the drive motor 3 causes the swing device 10 to deflect at an angle. The swing device 10 then moves the connecting plates 11 on both sides of the base 2, causing the connecting plates 11 to move synchronously with the U-shaped seat 12. The hydraulic cylinder 9 is fixed inside the U-shaped seat 12 by an external fixing clamp. The hydraulic cylinder 9 can adjust the orientation of the top column 75. The anti-splash mechanism 7 is deflected at an angle by the U-shaped seat 12, causing the pressure roller 4 to contact the ground. By aligning the external inflation component with the inflation port 73, air is added to the inflatable sealing skirt 71. The inflatable sealing skirt 71 effectively reduces the amount of gravel splashing during road repair. To enhance worker safety, the pressure rollers 4 are movably mounted on the inflatable plate 72 and can rotate between each other. When installation or disassembly is required, the quick-release mechanism 8 can quickly separate the fixed connection between the hydraulic cylinder 9 and the top column 75. The hydraulic cylinder 9 completes the structural fixation by inserting the locking block 83 into the insert block 81 and rotating the locking bolt 84 through the locking block 83. The same method can be used for quick disassembly, improving practicality. Several heating plates 5 are added inside the pressure rollers 4 to improve repair efficiency by reducing heat loss. A buffer device 6 is set on the heating plate 5 to reduce the amplitude of vibration caused by road bumps. The buffer spring 61 drives the buffer plate 62 to reduce vertical swaying. The lateral vibration damping is achieved by the extension and retraction of the damping rods 64 on both sides inside the sleeve 63.

[0032] Working principle: During use, the operator can move the base plate 1 and the overall structure by holding the handle 13 and driving the casters 14. The starter motor 3 drives the swing device 10 to rotate. The swing device 10 drives the connecting plates 11 at both ends to rotate through the top two sides. The connecting plates 11 drive the U-shaped seat 12 to move. The U-shaped seat 12 drives the hydraulic cylinder 9 to move. The locking bolt 84 is screwed to the clamp 83 through the quick release mechanism 8 to complete the fixed connection with the top column 75. The top column 75 drives the bottom pressure roller 4 to move down through the hydraulic cylinder 9, so that the pressure roller 4 moves to contact the road and bridge surface. The hydraulic cylinder 9 can adjust the position of the pressure roller 4 and the operator. Then, the heating plate 5 is started by the external power supply. Under the rolling action of the pressure roller 4, the road surface is repaired. When the road surface is bumpy, the buffer spring 61 and damping rod 64 in the buffer device 6 buffer and absorb the amplitude of vibration in different directions, so as to achieve a stabilizing effect. The external inflation device is aligned with the inflation port 73 to replenish the air into the inflatable sealing skirt 71, thereby effectively preventing the flying of gravel.
