Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a crack repair injector. Background Art

[0002] The construction of asphalt pavement repair projects is different from the construction of new pavement. The main difference is the treatment of asphalt pavement defects. Usually, in mild defects, after the original upper surface is milled, the edge of the crack in the lower surface is clear, and no branching cracks have developed. Usually, a slotting machine is used to expand the cracks, and then hot-melt polymer sealant is used to fill the cracks. Its functions are to seal the cracks to prevent water from seeping in and causing the disease to worsen, and to ensure the integrity of the lower surface.

[0003] The inventors have found that the current crack filling process mostly uses on-site gas furnace heating, and then transports to the crack for manual grouting. The temperature of the sealant can be controlled during heating, but the temperature cannot be accurately controlled during the filling process. Too high a temperature will easily cause the sealant to age, and too low a temperature will make it difficult for the sealant to be filled in. Manual grouting is not easy to fill the cracks, and the treatment effect is not good. Utility Model Content

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Please refer to Figure 1 The present embodiment provides a crack repair injector 100 for filling cracks in road surface with a crack sealant, which includes a flatbed trolley 10, a container 20, a valve 24, and a control component 30. The flatbed trolley 10 is provided with wheels 11 to facilitate the movement of the crack repair injector 100 on the road. The container 20 is fixedly mounted on the flatbed trolley 10 to contain the crack sealant. The container 20 is also provided with a discharge port 23. The valve 24 is connected to the discharge port 23 to control whether the discharge port 23 is opened or closed. The control component 30 is used to control the temperature in the container 20.

[0032] It is understandable that the flatbed truck 10 drives the container 20 to move on the road. When the flatbed truck 10 reaches the crack, the valve 24 is opened, and the crack filler flows out through the discharge port 23 and fills the crack to complete the crack filling. In this embodiment, the crack filling injector 100 is mainly used for filling cracks in asphalt pavement, and the main material of the crack filler is hot-melt polymer sealant.

[0033] Specifically, the control component 30 includes a temperature sensor 31 and a heater 32. The temperature sensor 31 is used to detect the temperature in the container 20. The heater 32 is used to heat the sealant in the container 20. In the present embodiment, the temperature sensor 31 is disposed in the container 20 to detect the temperature of the sealant in the container 20. The heater 32 is fixed to the flatbed vehicle 10 to heat the container 20. In the present embodiment, the heater 32 is a gas tank and a stove (not shown). In other embodiments, the heater 32 may be an electric heater 32, etc., which is not limited by the present utility model.

[0034] Furthermore, the control assembly 30 further includes a controller 33. In this embodiment, the controller 33 is fixedly connected to the flatbed vehicle 10. The controller 33 is electrically connected to the temperature sensor 31. The temperature sensor 31 converts the temperature signal in the container 20 into an electrical signal and transmits it to the controller 33.

[0035] Optionally, the controller 33 further includes a display panel 331. The display panel 331 is used to display the temperature in the container 20, so that construction workers can monitor the temperature of the sealant in real time.

[0036] In order to facilitate the construction personnel to control the opening and closing of the valve 24, in this embodiment, the crack repair injector 100 further includes a control handle 40. The control handle 40 is in transmission connection with the valve 24 and is used to control the opening or closing of the valve 24. It is understandable that since the discharge port 23 of the container 20 is close to the road surface and has a low height, the position of the valve 24 is low, and it is inconvenient for the construction personnel to operate. It is necessary to set the control handle 40 in transmission connection with the valve 24 so that one end of the control handle 40 is in a position that is convenient for the construction personnel to operate.

[0037] Specifically, in this embodiment, the control handle 40 mainly adopts a planar connecting rod mechanism, which includes a first transmission rod 41 and a second transmission rod 42. The first transmission rod 41 and the second transmission rod 42 are hinged, and one end of the second transmission rod 42 away from the first transmission rod 41 is connected to the valve 24. It can be understood that the construction personnel rotate one end of the first transmission rod 41 to drive the second transmission rod 42 to rotate, thereby driving the movement of the valve 24, and then controlling the discharge port 23 to open or close.

[0038] Furthermore, the crack filling injector 100 further includes a filling nozzle 25. The filling nozzle 25 is located below the discharge port 23 and is used to fill the crack. It is understood that when the crack filling agent flows out of the discharge port 23, it drips from top to bottom. In order to make the crack filling more uniform, a horizontal filling nozzle 25 is provided.

[0039] In order to adapt to cracks of different sizes, in the present embodiment, the filling nozzle 25 is detachably connected to the flatbed vehicle 10, and different filling nozzles 25 can be replaced according to the size of the crack.

[0040] Optionally, in order to close the container 20 , the container 20 includes a container cover 21 . The container cover 21 is provided with a handle 22 to facilitate opening or closing the container 20 .

[0041] In order to facilitate construction workers to move the flatbed truck 10 , a handle 12 is provided on the flatbed truck 10 .

[0042] The working principle and process of the crack repair injector 100 provided by the utility model are:

[0043] When it is necessary to fill the cracks in the road, the sealant is loaded into the container 20. The heater 32 is turned on to heat the container 20 so that the temperature of the sealant is stable and meets the construction requirements. The flatbed truck 10 is pushed and the discharge port 23 is aligned with the crack. The valve 24 is opened and the sealant is loaded into the crack by its own weight. The flatbed truck 10 is moved along the crack to evenly fill the sealant along the crack.

[0044] The beneficial effects of the crack repair injector 100 provided by the utility model are:

[0045] The crack repair injector 100 of the utility model includes a flatbed trolley 10, a container 20, a valve 24 and a control component 30. The flatbed trolley 10 is provided with wheels 11. The container 20 is fixedly mounted on the flatbed trolley 10 and is used to contain a sealant. The container 20 is also provided with a discharge port 23. The valve 24 is connected to the discharge port 23 and is used to control the discharge port 23 to be opened or closed. The control component 30 is used to control the temperature in the container 20. The crack repair injector 100 fixes the container 20 on the mobile flatbed trolley 10, and the control component 30 controls the temperature in the container 20 in real time, so that the temperature of the sealant during the repairing process can meet the use requirements, thereby improving the construction quality.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
