Description

Technical Field

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

[0002] Pavement damage can be generally divided into two categories: structural damage and functional damage. Structural damage leads to a decrease in the bearing capacity of the pavement structure, which is manifested in the form of various structural cracks. Functional damage affects driving quality and safety, manifested in a decrease in pavement service capacity, flatness and anti-skid performance. Usually, when structural damage increases to a certain extent, functional damage will also occur.

[0003] However, in the prior art, when an existing road surface is damaged and needs to be repaired, asphalt is generally used to fill and patch cracks in the road surface to achieve the purpose of repairing the road surface. Generally, after filling the road cracks with asphalt, the asphalt needs to be leveled to ensure the flatness of the repaired road. However, the two operations of asphalt filling and asphalt leveling are often performed separately, which slows down the work efficiency of road repair. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: generally after filling the road gaps with asphalt, the asphalt needs to be leveled to ensure the flatness of the repaired road, but the two operations of asphalt filling and asphalt leveling are often performed separately, which slows down the work efficiency of road repair.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a road damage repair device, comprising a mobile cart, a control box and a mobile power supply are arranged on the surface of the mobile cart, an asphalt storage tank is fixed to the upper surface of the mobile cart, and a feed port is arranged on the side of the asphalt storage tank, a motor is fixed to the top of the asphalt storage tank, a screw rod is fixed to the output end of the motor, and the upper end of the screw rod is connected through the asphalt storage tank and the lower end is rotatably connected to the asphalt storage tank, a push plate is threadedly connected to the surface of the screw rod, and the push plate is slidably connected to the asphalt storage tank, a discharge pipe is arranged at the bottom of the asphalt storage tank, and the discharge pipe is connected through the mobile cart, and an electromagnetic valve is arranged on the surface of the discharge pipe, a moving column is connected through one side of the mobile cart, and a blocking block is fixed to one end of the moving column, a connecting block is fixed to the other end of the moving column, and a smoothing roller is rotatably connected to one side of the connecting block, and a spring is sleeved on the outer surface of the moving column.

[0006] As a preferred embodiment, the surface of the asphalt storage tank is wrapped with a thermal insulation layer.

[0007] As a preferred implementation, a protective plate is fixedly connected to the surface of the asphalt storage tank.

[0008] As a preferred embodiment, two discharge pipes are provided at the bottom of the asphalt storage tank.

[0009] As a preferred embodiment, a lifting plate is fixedly connected to the blocking block of the moving column, and an interlaced column is slidably penetrated through the lifting plate, and the interlaced column is interlacedly connected to the moving cart.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model squeezes the asphalt in the asphalt storage tank through the cooperation of the screw rod and the push plate, so that it can flow out from the discharge pipe at an accelerated speed, and the asphalt storage tank is assisted by the mobile cart to move along the direction of the road cracks, so that the flowed asphalt can fill the road cracks. In the process of asphalt filling, the smoothing roller is closely attached to the ground with the help of the spring to facilitate the subsequent leveling effect. When the mobile cart is pushed, the smoothing roller is driven to roll on the ground, and the asphalt used to fill the gap is leveled to ensure the flatness of the road after repair. Since the two operations of asphalt filling and asphalt leveling are carried out closely, the work efficiency of road repair is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 2

[0021] like Figure 1-3As shown, the surface of the asphalt storage tank 2 is wrapped with an insulation layer 7, which plays an insulation role for the asphalt storage tank 2, effectively preventing the high-temperature asphalt in the asphalt storage tank 2 from losing temperature quickly and causing self-solidification. A protective plate 8 is fixedly connected to the surface of the asphalt storage tank 2, which plays a protective role for the insulation layer 7, effectively preventing the insulation layer 7 from detaching from the asphalt storage tank 2. Two discharge pipes 6 are provided at the bottom of the asphalt storage tank 2, which accelerate the filling of road cracks by increasing the outflow of asphalt. To improve efficiency, a lifting plate 12 is fixedly connected to the blocking block of the moving column 9, and an interlaced column 13 is slidably penetrated in the lifting plate 12, and the interlaced column 13 is interlaced with the moving cart 1. When the smoothing roller 10 is not needed to level the road surface, the smoothing roller 10 is lifted up by lifting the lifting plate 12 to break away from the contact with the ground, and then the moving cart 1 is interlaced by the interlaced column 13 to fix the lifting plate 12, so that the smoothing roller 10 can be stably suspended in the air, reducing unnecessary wear of the smoothing roller 10.

[0022] Working principle:

[0023] like Figure 1-3 As shown, when the utility model is in use, the user first fills the asphalt storage tank 2 with asphalt through the feed port, then closes the feed port, and then pushes the mobile cart 1 to the position of the road crack, and then pulls the interlaced column 13 on the lifting plate 12 outward to disengage the connection with the mobile cart 1, and then under the influence of the rebound of the contraction spring 11 on the moving column 9, the smoothing roller 10 is pushed and moved and then close to the ground, and then the motor 3 and the solenoid valve are controlled to open by the control box, and the motor 3 drives the screw rod 4 to rotate, so that the push plate 5 squeezes and moves the asphalt in the asphalt storage tank 2, and accelerates the outflow of asphalt from the discharge pipe 6. During this period, the mobile cart 1 is pushed to move in the extension direction of the road crack, and the outflowing asphalt fills the gap in the road. When the mobile cart 1 is pushed, the smoothing roller 10 is driven to roll on the ground, and the asphalt used to fill the gap is leveled to ensure the flatness of the road after repair.
