Description

Technical Field

[0001] This utility model belongs to the field of road and bridge construction technology, and specifically relates to a road surface maintenance machine. Background Technology

[0002] After prolonged use, road and bridge surfaces develop cracks and depressions due to vehicle traffic, requiring regular maintenance to fill these areas. During maintenance, operators move a maintenance machine loaded with asphalt filler across the road, releasing asphalt into cracked or depressed areas. The asphalt is released directly downwards through fixed nozzles, resulting in a fixed release point and height. This method is ineffective in distributing asphalt across varying heights and depths within the filling area. When filling irregular, long cracks, frequent machine movement complicates the process and reduces efficiency. Utility Model Content

[0003] This utility model provides a road maintenance machine that improves the filling and maintenance effect of the filled area and increases work efficiency.

[0004] This utility model provides the following technical solution: It includes a maintenance vehicle body and a maintenance tank fixed to the top of the maintenance vehicle body. A liquid pump is fixedly connected to the outer wall of the maintenance tank. Several release components are provided at the front of the maintenance vehicle body. Each release component includes a lifting drive, a release head, and a corrugated connecting pipe. The release head moves vertically in front of the liquid pump via the lifting drive and is connected to the liquid pump via the corrugated connecting pipe. Several adjustment components corresponding to the release components are provided above the maintenance vehicle body. Each adjustment component includes a connecting plate and an adjusting rod. The connecting plate moves horizontally above the liquid pump via the adjusting rod and is connected to the fixed end corresponding to the lifting drive.

[0005] The maintenance vehicle body has a fixed plate fixedly connected to the top, the liquid pump is located inside the fixed plate, and the outer wall of the liquid pump is fixedly connected to the inner wall of the fixed plate.

[0006] The connecting plate is located above the fixed plate. A guide block is fixedly connected to the bottom of the lower end of the connecting plate. The top of the fixed plate has several guide grooves corresponding to the connecting plate. The guide block is slidably connected inside the corresponding guide block.

[0007] The adjusting rod is fixedly connected to the outer wall of the connecting plate, and several sleeves corresponding to the adjusting rod are fixedly connected inside the curing tank, with the adjusting rod inserted into the corresponding sleeve.

[0008] The fixed end of the lifting drive component is fixedly connected to the bottom of the corresponding high end of the connecting plate, and the release head is fixedly connected to the output end of the lifting drive component.

[0009] The corrugated connecting pipe is located below the liquid pump, and its two ends are fixedly connected to the output end of the liquid pump and the outer wall of the release head, respectively.

[0010] The bottom of the pump is close to the top of the maintenance vehicle body, and the output end of the pump is exposed at the front of the maintenance vehicle body.

[0011] The beneficial effects of this utility model are:

[0012] This invention, through the installation of a fixed plate and multiple adjusting components, laterally positions multiple release components in front of the maintenance tank on the maintenance vehicle body. When the pump on the maintenance tank is activated, it releases the filling asphalt onto the release heads of the release components, which then discharge the asphalt. The release heads are vertically movable under the control of a lifting drive component to adjust the depth into the filling area. Pushing the adjusting rod allows the release heads to move horizontally via a connecting plate, adjusting the position of each release head. During road maintenance operations, the release heads can be effectively adjusted according to the state and depth of the cracks being filled, allowing for efficient asphalt release from different heights and depths within the crack filling area. This design flexibly adapts to filling irregular long cracks, improving the road surface filling and maintenance effect and increasing work efficiency.

[0019] Please see Figures 1-4 The present invention provides the following technical solution: a maintenance vehicle body 1 and a maintenance tank 2 fixed on the top of the maintenance vehicle body 1. A liquid pump 21 is fixedly connected to the outer wall of the maintenance tank 2. Several release components 3 are provided in front of the maintenance vehicle body 1. The release components 3 include a lifting drive 31, a release head 32 and a corrugated connecting pipe 33. The release head 32 moves vertically in front of the liquid pump 21 through the lifting drive 31 and is connected to the liquid pump 21 through the corrugated connecting pipe 33. Several adjustment components 4 corresponding to the release components 3 are provided on the top of the maintenance vehicle body 1. The adjustment components 4 include a connecting plate 41 and an adjusting rod 42. The connecting plate 41 moves horizontally above the liquid pump 21 through the adjusting rod 42 and is connected to the fixed end of the corresponding lifting drive 31.

[0020] In this implementation scheme: the maintenance vehicle body 1 is used to connect the maintenance tank 2, multiple release components 3, and multiple adjustment components 4, and moves on the road surface. The maintenance tank 2 is fixed to the top of the maintenance vehicle body 1, and the liquid extraction pump 21 is fixed to the outer wall of the maintenance tank 2. The maintenance tank 2 is used to store maintenance asphalt. When the liquid extraction pump 21 is activated, it can extract the asphalt from the inside of the maintenance tank 2 and discharge it through the output end. A fixing plate 11 is fixedly connected to the top of the maintenance vehicle body 1, and the liquid extraction pump 21 is located inside the fixing plate 11. The outer wall of the liquid extraction pump 21 is fixedly connected to the inner wall of the fixing plate 11, which improves the stability of the liquid extraction pump 21 on the maintenance vehicle body 1.

[0021] Release assembly 3 is located at the front of maintenance vehicle body 1. The number of adjustment assemblies 4 corresponds to the number of release assembly 3. Multiple adjustment assemblies 4 are horizontally connected above maintenance vehicle body 1 and are connected and positioned to correspond to the release assembly 3. Adjustment assembly 4 consists of connecting plate 41 and adjustment rod 42. Connecting plate 41 is located above fixed plate 11. Guide block 411 is fixedly connected to the bottom of the lower end of connecting plate 41. Several guide grooves 111 corresponding to connecting plate 41 are opened on the top of fixed plate 11. Guide block 411 is slidably connected inside the corresponding guide block 411, stably connecting connecting plate 41 above fixed plate 11. Connecting plate 41 can move horizontally above fixed plate 11 through the cooperation of guide block 411 and guide groove 111. The adjusting rod 42 is fixedly connected to the outer wall of the connecting plate 41. Several corresponding sleeves 22 are fixedly connected inside the curing tank 2. The adjusting rod 42 is inserted into the corresponding sleeve 22. By pushing the adjusting rod 42, the operator can control the movement of the connecting plate 41 above the fixed plate 11, facilitating the adjustment of the connecting plate 41's position. The sleeves 22 on the curing tank 2 provide space for the adjusting rod 42 to pass through, ensuring its normal operation.

[0022] The release assembly 3 consists of a lifting drive 31, a release head 32, and a corrugated connecting pipe 33. The fixed end of the lifting drive 31 is fixedly connected to the bottom of the corresponding high end of the connecting plate 41. The release head 32 is fixedly connected to the output end of the lifting drive 31. The corrugated connecting pipe 33 is located below the liquid pump 21, and its two ends are fixedly connected to the output end of the liquid pump 21 and the outer wall of the release head 32, respectively, stably connecting the release assembly 3 with the corresponding adjusting assembly 4. This positions the release head 32 in front of the liquid pump 21, and the corrugated connecting pipe 33 stably connects the release head 32 to the liquid pump 21. The lifting drive 31 can be an electric push rod. Under the control of the lifting drive 31, the release head 32 can move vertically in front of the liquid pump 21, allowing it to move vertically towards the crack filling area on the road surface. The release head 32 can enter the crack and continue to move inside, adjusting its position inside the crack. When the pump 21 is activated, it draws out the curing asphalt and guides it through the corrugated connecting pipe 33 into the release head 32, where it is then released directly into the crack. The bottom of the pump 21 is close to the top of the maintenance vehicle body 1, and the output end of the pump 21 protrudes from the front of the maintenance vehicle body 1, ensuring that the release head 32 can move normally in front of the maintenance vehicle body 1, while also ensuring that the corrugated connecting pipe 33 extends and retracts to return to its original position following the release head 32.

[0023] The fixed plate 11 on the top of the maintenance vehicle body 1 cooperates with multiple adjusting components 4 to laterally position multiple release components 3 in front of the maintenance tank 2 on the maintenance vehicle body 1. The pump 21 on the maintenance tank 2 is activated, which releases the filling asphalt into the release head 32 on the release component 3, and discharges it downwards from the release head 32. The release head 32 is vertically moved by the lifting drive component 31 to adjust the depth of the release head 32 into the filling area. Pushing the adjusting rod 42 causes the connecting plate 41 to move horizontally above the fixed plate 11. The connecting plate 41 drives the release component 3 to move horizontally in front of the maintenance vehicle body 1. The corrugated connecting pipe 33 undergoes adaptive stretching deformation, allowing the release head 32 to stably complete the horizontal movement. Each adjusting component 4 and release component 3 exists independently to facilitate adjustment of the position of each release head 32. During road maintenance operations, the release head 32 can be effectively adjusted according to the state and depth of the cracks to effectively release asphalt from different heights and depths in the crack filling area. It can flexibly adapt to the filling of irregular long cracks, improve the filling and maintenance effect of the road surface, and increase work efficiency.
