Description

Technical Field

[0001] This utility model relates to a highway crack grouting device, specifically a portable grouting device for rapid filling and repair of highway cracks, belonging to the technical field of highway crack grouting devices. Background Technology

[0002] In real life, we can see that highways are subjected to repeated crushing by a large number of vehicles over a long period of time, especially overloaded vehicles such as heavy trucks, which can cause fatigue damage to the road surface structure. When the road surface material exceeds its bearing capacity, cracks will be caused. At the same time, the impact force generated by vehicles when they are driving, such as sudden braking and acceleration, will put additional pressure on the road surface, which can easily cause local cracks to appear. For the safety of vehicles, people need to repair them by grouting.

[0003] When cracks are discovered on a highway, workers need to carry grouting equipment to fill and repair the cracks. When dealing with crack repair work on different road sections, the heavy weight of the grouting equipment makes it extremely inconvenient to carry. Frequent site transfers require a lot of manpower, which seriously affects the efficiency of highway crack repair and makes it difficult to meet the requirements of efficient operation.

[0004] Therefore, a portable grouting device for rapid filling and repair of highway cracks is proposed here. Utility Model Content

[0005] This invention proposes a portable grouting device for rapid filling and repair of highway cracks, in order to solve the problem that existing grouting devices are not easy to carry.

[0006] This utility model is achieved through the following technical solution: a portable grouting device for rapid filling and repair of highway cracks, including a grouting cylinder, a moving mechanism provided on the outer surface of the grouting cylinder, the moving mechanism including a first fixed frame, symmetrical fixed blocks fixedly connected to the outer surface of the first fixed frame, support plates rotatably connected to the inner walls of the two fixed blocks, limit posts slidably connected to the inner walls of the two support plates, handles fixedly connected to the tops of the two limit posts, springs fixedly connected to the side of the handles near the fixed blocks, and moving wheels rotatably connected to the bottom ends of the two support plates.

[0007] Furthermore, the first fixing frame is fixedly connected to the outer surface of the grouting cylinder, and the limiting post extends to the outside of the fixing block and is slidably connected to the fixing block, so that the grouting cylinder can support the first fixing frame.

[0008] Specifically, the spring is fixedly connected to the fixing block, and the spring is sleeved on the outer surface of the limiting post. The fixing block can fix the spring, while the spring can also reset.

[0009] Specifically, a second fixing frame is fixedly connected to the outer surface of the grouting cylinder, and a set of fixing legs is fixedly connected to the bottom surface of the second fixing frame. Each fixing leg is fixedly connected to the upper surface of the first fixing frame, and people can use their hands to hold the fixing legs to move or perform filling operations.

[0010] Preferably, a cylinder cover is installed on the upper surface of the grouting cylinder, and a screw rod is rotatably connected to the inner wall of the cylinder cover. The cylinder cover is installed on the upper surface of the grouting cylinder with screws, and the top end of the screw rod passes through the cylinder cover.

[0011] Furthermore, a pressure plate is threadedly connected to the outer surface of the lead screw, and the pressure plate is slidably connected to the inner wall of the grouting cylinder. A motor is installed on the upper surface of the cylinder cover, and the output end of the motor is fixedly connected to the top of the lead screw. Grout can be injected into the grouting cylinder through the grouting pipe. A protrusion is fixed on the outer surface of the pressure plate and is adapted to the groove opened in the inner wall of the grouting cylinder, so that the pressure plate can be driven to move downward under the rotation of the lead screw, thereby injecting the grout into the cracks of the road through the grout discharge pipe.

[0012] This utility model provides a portable grouting device for rapid filling and repair of highway cracks, which has the following beneficial effects:

[0013] 1. The portable grouting device for rapid filling and repair of highway cracks is designed with a grouting cylinder and a moving mechanism. By flipping the support plate downwards until the moving wheels contact the ground, people can push the device with the fixed legs, making it convenient to carry during frequent site changes.

[0014] 2. This portable grouting device for rapid filling and repair of highway cracks is designed with a handle, a limiting post, a spring, a support plate, and a moving wheel in tandem. By pulling the handle outward until the limiting post releases the limiting position on the support plate, and then flipping the support plate downward until the moving wheel contacts the ground, the handle is released and the support plate is limited by the spring. Then, people can move the device by pushing it with the help of the moving wheel. Attached Figure Description
