Description

Technical Field

[0001] The utility model belongs to the technical field of pavement sealing, and in particular relates to pavement sealing equipment for urban road maintenance. Background Art

[0002] During the long-term use of urban roads, affected by factors such as traffic load and climate change, the road surface is prone to cracks and damage. If these cracks are not repaired in time, they will aggravate the impact of water infiltration, freeze-thaw and traffic load, further leading to road damage and structural damage. In order to extend the service life of roads and improve driving safety, pavement sealing technology has come into being. Pavement sealing equipment can effectively fill cracks and prevent water intrusion, while enhancing the overall performance of the road surface and reducing maintenance costs. Therefore, regular maintenance of urban roads requires efficient and precise sealing equipment.

[0003] A Chinese patent with patent publication number CN219450385U discloses an asphalt pavement sealing machine, comprising a barrel and a nozzle. The barrel is connected to the nozzle, a nozzle is provided at one end of the nozzle away from the barrel, a connecting pipe is provided at the connection between the nozzle and the nozzle, and an adjustment mechanism is provided on the nozzle, which is used to adjust the diameter of the connecting pipe. This patent has the effect of improving the efficiency of filling pavement cracks.

[0004] However, the current sealing machine has the following problems: the nozzle head of the sealing machine is blocked by the solidified filler in cold weather, which seriously affects the fluidity of the sealing material and cannot be smoothly sprayed into the cracks through the nozzle, resulting in the inability to proceed normally, affecting the maintenance progress and causing damage to equipment such as the nozzle and pump system. Therefore, we proposed a pavement sealing equipment for urban road maintenance. Utility Model Content

[0006] The technical solutions adopted by this utility model are as follows:

[0007] The top of the base plate is fixed with a barrel device, the inner wall of the barrel device is fixedly connected to the nozzle, and the top of the base plate is provided with an anti-blocking device. The anti-blocking device includes a support rod, the bottom of the support rod is fixedly connected to the top of the base plate, the top of the support rod is fixedly connected to an electric telescopic rod, the telescopic end of the electric telescopic rod is fixedly connected to a round block, the outer wall of the nozzle is fixedly connected to a telescopic shell, the top of the base plate is fixedly connected to a placing plate, the side of the placing plate is rotatably connected to a rotating column, the rotating column is driven by a motor, and the motor is fixedly connected to the side of the placing plate, the outer wall of the nozzle is fixedly connected to a supercharged shell, the inner wall of the supercharged shell is slidably connected to a sliding block, the side of the sliding block is fixedly connected to an L-shaped moving rod, the circumferential surface of the nozzle is fixedly connected to a fixed block, the circumferential surface of the nozzle is fixedly connected to an insulation pipe, the bottom of the base plate is provided with a wheel device, and the top of the base plate is fixedly connected to a pull rod.

[0008] The fixed block contacts the bottom plate, and the side surface of the round block contacts the inner wall of the telescopic shell.

[0009] The circumferential surface of the rotating column is provided with a notch for facilitating the movement of the L-shaped moving rod, and the circular surface of the L-shaped moving rod is in contact with the notch of the rotating column.

[0010] A scraping device is provided on the side of the base plate, and the scraping device includes a stopper, and the side of the stopper is fixedly connected to the side of the base plate. The circumferential surface of the long rod of the L-shaped moving rod is hinged with a hinged rod, and the end of the hinged rod away from the L-shaped moving rod is hinged with a vertical short plate, and the bottom of the vertical short plate is fixedly connected to a horizontal long plate, and the bottom of the horizontal long plate is fixedly connected to a triangular plate.

[0011] The stopper is located on the movement track of the hinged rod, and a gap is left between the horizontal long plate and the nozzle.

[0012] The material of the triangular plate is set to polyurethane, and a gap is left between the triangular plate and the nozzle.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model adopts the arrangement of the anti-clogging device so that the electric telescopic rod, the round block, the telescopic shell, the nozzle, the insulation tube, the rotating column, the L-shaped moving rod, the sliding block and the pressurized shell are coordinated. When the electric telescopic rod is started, the movement of the telescopic end of the electric telescopic rod drives the movement of the round block in the telescopic shell, and stops when it hits the inner wall of the nozzle, thereby sealing the lower half of the nozzle that is not wrapped by the insulation tube. The motor corresponding to the rotating column is started, and the rotation of the motor output shaft drives the rotation of the rotating column. The rotation of the rotating column drives the movement of the L-shaped moving rod. The movement of the L-shaped moving rod drives the sliding block to move in the pressurized shell, thereby squeezing the air in the nozzle, so that the filler that is solidified and blocked at the tip of the nozzle in cold weather can be removed from the nozzle.

[0015] The utility model adopts the arrangement of the scraping device to ensure the coordination of the L-shaped moving rod, the hinged rod, the vertical short plate, the horizontal long plate, the triangular plate and the nozzle. When the L-shaped moving rod moves outward, it drives the hinged rod to move outward. The outward movement of the hinged rod drives the hinged rod downward. The downward movement of the hinged rod drives the vertical short plate downward. The downward movement of the vertical short plate drives the horizontal long plate downward. The downward movement of the horizontal long plate drives the triangular plate downward. When the triangular plate touches the ground, it stops moving. When the trolley moves forward, the nozzle fills the filling material and the triangular plate scrapes the filling material flat, so that the ground is more flat and convenient for vehicles to pass.
