Description

Technical Field

[0001] The utility model relates to a municipal road surface repair device, belonging to the technical field of road surface repair. Background Art

[0002] After a period of use, the road surface is prone to cracks due to factors such as roadbed settlement. When repairing the road surface cracks, molten asphalt is often added to a rectangular frame, and the upper and lower ends of the frame are open, so that the frame moves along the direction of the cracks, so that the asphalt in the frame flows into the cracks to repair the road surface cracks. At present, the volume of the frame used to store asphalt is fixed, while the width of the road surface cracks is different. When the frame is used to store molten asphalt, more asphalt is smeared on the area far away from the cracks, thereby increasing the asphalt consumption and reducing the asphalt utilization rate. Therefore, it is necessary to design a municipal road surface repair device that can adjust the space width of the asphalt storage according to the width of the road surface cracks. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a municipal pavement repair device to solve the problems raised in the above-mentioned background technology. The utility model can adjust the width of the space for storing asphalt according to the width of the pavement cracks, thereby improving the utilization rate of asphalt.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a municipal pavement repair device, including a U-shaped frame, a push rod is installed on one side of the U-shaped frame, a baffle is slidably installed in the U-shaped frame, a vertical plate is connected and fixed at an edge of one side of the upper surface of the baffle, a support plate is connected and fixed on the side of the upper surface of the U-shaped frame close to the push rod, a horizontally arranged cross plate is connected and fixed on the upper end of the support plate, two strip grooves are symmetrically provided on one side of the cross plate, the strip grooves are arranged along the length direction of the cross plate, the upper end of the vertical plate is in contact with the cross plate, and two studs matching the strip grooves are connected and fixed at the upper position of one side surface of the vertical plate, the studs penetrate the strip grooves, nuts are threaded on the studs, and the nuts are arranged on the side of the cross plate away from the vertical plate.

[0005] Furthermore, a wear-resistant bottom edge is installed at the bottom of the U-shaped frame, and the wear-resistant bottom is a U-shaped structure.

[0006] Furthermore, wear-resistant strips are installed on the lower surface of the baffle, and the wear-resistant strips are arranged along the length direction of the baffle.

[0007] Furthermore, a rubber sleeve is sleeved on one end of the push rod away from the U-shaped frame, one end of the rubber sleeve is closed, a plurality of annular protrusions are evenly fixed on the outer surface of the rubber sleeve, and the annular protrusions and the rubber sleeve are an integrally formed structure.

[0008] Furthermore, an inclined hole is provided at the position where the push rod is installed in the U-shaped frame, the inclined hole is inclined upward, and one end of the push rod is connected and fixed in the inclined hole.

[0009] Furthermore, the support plate and the transverse plate are an integrally formed structure, and the support plate and the transverse plate are arranged perpendicular to each other.

[0010] Furthermore, two blind holes are provided at the upper part of one side of the vertical plate facing the horizontal plate, and one end of the stud is connected and fixed in the blind hole.

[0011] Furthermore, the vertical plate and the baffle are an integrally formed structure, and the vertical plate and the baffle are arranged perpendicular to each other.

[0012] Beneficial effects of the utility model:

[0013] 1. According to the width of the road cracks, the position of the baffle in the U-shaped frame is adjusted. At this time, the width of the space formed by the baffle and the U-shaped frame for storing molten asphalt changes, so that the width of the space for storing asphalt can be adjusted with the width of the road cracks, reducing the amount of asphalt smeared on the road surface away from the crack area and improving the utilization rate of asphalt.

[0014] 2. When adjusting the position of the baffle, the baffle drives the vertical plate to move, and the vertical plate drives the stud to move along the strip groove. When the relative position of the baffle and the U-shaped frame meets the requirements of the crack width, screw the nut on the stud to fix the relative position of the vertical plate and the horizontal plate. That is, the relative position of the baffle and the U-shaped frame is restricted. Under the action of the vertical plate and the support plate, the stud and the nut are kept away from the U-shaped frame to prevent the molten asphalt from adhering to the stud and the nut.

[0015] 3. Install a wear-resistant bottom edge at the bottom of the U-shaped frame and a wear-resistant strip at the lower end of the baffle to avoid direct contact between the U-shaped frame and the baffle and the road surface, thereby protecting the U-shaped frame and the baffle. There is no need to use materials with good wear resistance to produce the U-shaped frame and the baffle, thereby reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end of the vertical plate 6 is provided with a plurality of studs 12 which are matched with the strip grooves 11. The upper end of the vertical plate 6 is provided with a plurality of studs 12 which are matched with the strip grooves 11. The threaded connection is provided with a nut 8, which is arranged on the side of the horizontal plate 7 away from the vertical plate 6. According to the width of the road crack, the position of the baffle 10 in the U-shaped frame 1 is adjusted. At this time, the width of the space formed by the baffle 10 and the U-shaped frame 1 for storing molten asphalt changes, so that the width of the space for storing asphalt is adjusted along with the width of the road crack, reducing the amount of asphalt smeared on the road surface away from the crack area, and improving the utilization rate of asphalt. When the position of the baffle 10 is adjusted, the baffle 10 drives the vertical plate 6 to move, and the vertical plate 6 drives the stud 12 to move along the strip groove 11. When the relative position of the baffle 10 and the U-shaped frame 1 meets the requirement of the crack width, the nut 8 is screwed on the stud 12 to fix the relative position of the vertical plate 6 and the horizontal plate 7, that is, the relative position of the baffle 10 and the U-shaped frame 1 is restricted. Under the action of the vertical plate 6 and the support plate 9, the stud 12 and the nut 8 are kept away from the U-shaped frame 1 to prevent the molten asphalt from adhering to the stud 12 and the nut 8.

There is no need to use materials with good wear resistance to produce the U-shaped frame 1 and the baffle 10, thereby reducing production costs.

[0025] Specific implementation method: According to the width of the road crack, the position of the baffle 10 in the U-shaped frame 1 is adjusted. At this time, the width of the space formed by the baffle 10 and the U-shaped frame 1 for storing molten asphalt changes, so that the width of the space for storing asphalt can be adjusted along with the width of the road crack, reducing the amount of asphalt smeared on the road surface away from the crack area, and improving the utilization rate of asphalt. When the position of the baffle 10 is adjusted, the baffle 10 drives the vertical plate 6 to move, and the vertical plate 6 drives the stud 12 to move along the strip groove 11. When the relative position of the baffle 10 and the U-shaped frame 1 meets the requirement of the crack width, the nut 8 is screwed on the stud 12 to fix the relative position of the vertical plate 6 and the horizontal plate 7, that is, the relative position of the baffle 10 and the U-shaped frame 1 is restricted. Under the action of the vertical plate 6 and the support plate 9, the stud 12 and the nut 8 are kept away from the U-shaped frame 1 to prevent the molten asphalt from adhering to the stud 12 and the nut 8.
