Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, and particularly to a pavement repair device. Background Art

[0002] Due to settlement and other reasons, cracks will appear in the municipal road surface. Usually, molten asphalt is poured into the gaps in the road surface. Usually, a thinner discharge pipe is installed at one end of a hollow pipe connected to a hose for transporting asphalt. The discharge pipe is rotatably installed in a limit frame for restricting the diffusion range of asphalt. During the process of repairing the road surface gap, a person holds the hollow pipe by hand and moves the limit frame along the road surface crack. Thus, under the restriction of the limit frame, the molten asphalt flowing out of the discharge pipe flows into the road surface gap. Because the hollow pipe is long and the thinner discharge pipe is rotatably installed in the limit frame, affected by the shapes of the limit frame and the hollow pipe, during storage or transportation, the thinner discharge pipe is prone to being squeezed and deformed and bent, resulting in damage to the discharge pipe. Therefore, it is necessary to design a pavement repair device that can prevent the discharge pipe from being damaged by extrusion. Content of the Utility Model

[0003] Aiming at the technical problems existing in the prior art, the utility model provides a pavement repair device, which forms a triangular structure jointly by a hollow pipe, a limit frame and an L-shaped plate, so that the relative positions of the limit frame and the hollow pipe remain unchanged. Furthermore, when an external force acts on the limit frame, the force received by the limit frame will act on the hollow pipe through the L-shaped plate, avoiding the connection part between the thinner discharge pipe and the limit frame from bearing a large extrusion force, preventing the thinner discharge pipe from being squeezed and bent and deformed, and playing a role in protecting the discharge pipe.

[0004] The utility model is realized through the following technical solutions:

[0005] A pavement repair device includes a limit frame and a hollow pipe for transporting molten asphalt. A handle is installed at one end of the hollow pipe. A pipe joint for connecting a hose for transporting molten asphalt is installed on the outer surface of the hollow pipe near the handle. A reducing pipe is fixedly connected to the end of the hollow pipe far from the handle; the reducing pipe is connected with a discharge pipe, and the discharge pipe is rotatably installed in the limit frame; a pipe sleeve fixedly connected to the hollow pipe is sleeved on the hollow pipe; a detachable L-shaped plate is installed at the lower position on the outer surface of the pipe sleeve; the L-shaped plate is detachably connected to the limit frame through a detachable component.

[0006] Further, as an improvement of the technical solution of the utility model, the detachable component includes a slot and a plug board; the slot is opened at one end of the L-shaped plate facing the limit frame; the plug board is installed on the outer side wall of the limit frame; the plug board is inserted into the slot.

[0007] As a further improvement of the utility model technical solution, a support rod is fixedly connected to the lower position of the outer surface of the pipe sleeve, and one end of the L-shaped plate is in contact with the support rod.

[0008] As a further improvement of the utility model technical solution, a perforation is provided at the contact part between the support rod and the L-shaped plate, and a connecting screw threadedly connected to the L-shaped plate is inserted into the perforation.

[0009] As a further improvement of the utility model technical solution, a threaded hole aligned with the perforation is provided at the contact part between the L-shaped plate and the support rod, and one end of the connecting screw is threadedly connected to the threaded hole.

[0010] As a further improvement of the utility model technical solution, a cylinder is provided on the side of the threaded hole away from the perforation. The open end of the cylinder is fixedly connected to the L-shaped plate. A spring is installed in the cylinder. One end of the spring is fixedly connected to a stud for blocking the threaded hole, and the stud is slidably installed in the threaded hole.

[0011] As a further improvement of the utility model technical solution, two shaft rods are symmetrically and fixedly connected to the outer surface of the discharge pipe. Shaft holes matching the shaft rods are provided on two parallel side surfaces of the limit frame, and one end of the shaft rod away from the discharge pipe is inserted into the shaft hole.

[0012] As a further improvement of the utility model technical solution, a pipe sleeve fixedly connected to the hollow pipe is sleeved on the hollow pipe, and a grip handle is fixedly connected to the upper position of the outer surface of the pipe sleeve.

[0013] As a further improvement of the utility model technical solution, a limit disk is installed at one end of the shaft rod away from the discharge pipe. The limit disk is arranged outside the limit frame and the limit disk is in sliding contact with the surface of the limit frame.

[0014] As a further improvement of the utility model technical solution, an external threaded pipe is installed at one end of the reducing pipe away from the hollow pipe. A hexagonal threaded cap is fixedly connected to one end of the discharge pipe close to the external threaded pipe, and the hexagonal threaded cap is threadedly connected to the external threaded pipe.

[0015] The beneficial effects of the present utility model:

[0016] When the present utility model is stored, the insertion plate on the limit frame is inserted into the slot on the L-shaped plate to realize the insertion connection between the L-shaped plate and the limit frame. Then, the support rod and the L-shaped plate are connected by a connecting screw. At this time, the hollow pipe, the limit frame and the L-shaped plate together form a triangular structure, so that the relative position between the limit frame and the hollow pipe remains unchanged. Furthermore, when an external force acts on the limit frame, the force received by the limit frame will act on the hollow pipe through the L-shaped plate, avoiding a large extrusion force on the connection part between the relatively thin discharge pipe and the limit frame, preventing the relatively thin discharge pipe from being squeezed and bent, and playing a role in protecting the discharge pipe.

[0017] When the connecting screw is passed through the through hole and screwed into the threaded hole, the connecting screw squeezes the column head, and the column head squeezes the spring, causing the spring to retract into the cylinder. Under the action of the spring rebound force, the probability of the connecting screw loosening is reduced. When the connecting screw is disengaged from the threaded hole, the column head is moved into the threaded hole and flush with the end of the threaded hole under the action of the spring rebound force, thereby achieving real-time blocking of the threaded hole and preventing small debris from entering the threaded hole at will.

[0030] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] Referring to Figures 1 to 7 , the present utility model relates to a road surface repair device, including a limit frame 11 and a hollow tube 1 for conveying molten asphalt. One end of the hollow tube 1 is installed with a handle 2. An outer surface of the hollow tube 1 near the handle 2 is installed with a pipe joint 3 for connecting a hose for conveying molten asphalt. The end of the hollow tube 1 far from the handle 2 is fixedly connected with a reduced-diameter pipe 19; the reduced-diameter pipe 19 is connected with a discharge pipe 10, and the discharge pipe 10 is rotatably installed in the limit frame 11; a pipe sleeve 4 fixedly connected with the hollow tube 1 is sleeved on the hollow tube 1; a detachable L-shaped plate 8 is installed at a lower position on the outer surface of the pipe sleeve 4; the L-shaped plate 8 is detachably connected with the limit frame 11 through a detachable component.

[0032] Specifically, in the solution of this embodiment, the detachable component includes a slot 12 and a plug board 15; the slot 12 is opened at one end of the L-shaped plate 8 facing the limit frame 11; the plug board 15 is installed on the outer side wall of the limit frame 11; the plug board 15 is inserted into the slot 12.

[0033] Specifically, in the solution of this embodiment, a support rod 6 is fixedly connected to the lower position of the outer surface of the pipe sleeve 4, and one end of the L-shaped plate 8 is attached to the support rod 6.

[0034] Specifically, in the solution of this embodiment, a through hole 16 is provided at the contact part between the support rod 6 and the L-shaped plate 8, and a connecting screw 7 threadedly connected to the L-shaped plate 8 is inserted into the through hole 16.

[0035] When the utility model is stored, the insertion plate 15 on the limit frame 11 is inserted into the slot 12 on the L-shaped plate 8 to realize the insertion connection between the L-shaped plate 8 and the limit frame 11. Then, the support rod 6 and the L-shaped plate 8 are connected by the connecting screw 7. At this time, the hollow tube 1, the limit frame 11 and the L-shaped plate 8 jointly form a triangular structure, so that the relative position between the limit frame 11 and the hollow tube 1 remains unchanged. Furthermore, when an external force acts on the limit frame 11, the force received by the limit frame 11 will act on the hollow tube 1 through the L-shaped plate 8, avoiding a large extrusion force on the connection part between the thinner discharge pipe 10 and the limit frame 11, preventing the thinner discharge pipe 10 from being squeezed and bent, and playing a role in protecting the discharge pipe 10.

[0036] Specifically, in the solution of this embodiment, a threaded hole 13 aligned with the through hole 16 is provided at the contact part between the L-shaped plate 8 and the support rod 6, and one end of the connecting screw 7 is threadedly connected to the threaded hole 13.

[0037] Specifically, in the solution of this embodiment, a cylinder 9 is provided on the side of the threaded hole 13 away from the through hole 16.

One end of the spring 23 is fixedly connected to a plug 22 for blocking the threaded hole 13, and the plug 22 is slidably installed in the threaded hole 13. When the connecting screw 7 is passed through the through hole 16 and screwed into the threaded hole 13, the connecting screw 7 presses the plug 22, and the plug 22 presses the spring 23, causing the spring 23 to retract into the cylinder 9. Under the action of the resilience of the spring 23, the probability of the connecting screw 7 loosening is reduced. When the connecting screw 7 is separated from the threaded hole 13, under the action of the resilience of the spring 23, the plug 22 moves into the threaded hole 13 and is flush with the end of the threaded hole 13, realizing the real-time blocking of the threaded hole 13 and preventing small sundries from randomly entering the threaded hole 13.

The limiting disk 18 is arranged outside the limiting frame 11 and the surface of the limiting disk 18 is in sliding contact with the surface of the limiting frame 11.

[0041] Specifically, in the solution of this embodiment, an external threaded pipe 20 is installed at one end of the reducing pipe 19 away from the hollow tube 1. One end of the discharge pipe 10 close to the external threaded pipe 20 is connected and fixed with a hexagonal threaded cap 21, and the hexagonal threaded cap 21 is in threaded connection with the external threaded pipe 20.

[0042] Compared with the existing technology, the beneficial effects of the present utility model are as follows:

[0043] When the present utility model is stored, the insertion plate 15 on the limiting frame 11 is inserted into the slot 12 on the L-shaped plate 8 to realize the insertion connection between the L-shaped plate 8 and the limiting frame 11. Then, the connecting screw 7 is used to connect the support rod 6 and the L-shaped plate 8. At this time, the hollow tube 1, the limiting frame 11 and the L-shaped plate 8 jointly form a triangular structure, so that the relative position between the limiting frame 11 and the hollow tube 1 remains unchanged. Furthermore, when an external force acts on the limiting frame 11, the force received by the limiting frame 11 will act on the hollow tube 1 through the L-shaped plate 8, avoiding a large extrusion force on the connection part between the relatively thin discharge pipe 10 and the limiting frame 11, preventing the relatively thin discharge pipe 10 from being squeezed and bent, and playing a role in protecting the discharge pipe 10. When the connecting screw 7 is passed through the through hole 16 and screwed into the threaded hole 13, the connecting screw 7 presses the stud 22, and the stud 22 presses the spring 23, so that the spring 23 retracts into the cylinder 9. Under the action of the resilience of the spring 23, the probability of the connecting screw 7 loosening is reduced. When the connecting screw 7 disengages from the threaded hole 13, under the action of the resilience of the spring 23, the stud 22 moves into the threaded hole 13 and is flush with the end of the threaded hole 13, realizing the real-time blocking of the threaded hole 13 and preventing small sundries from randomly entering the threaded hole 13.
