Description

Technical Field

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

[0002] With the booming development of the transportation industry and the rapid development of industry, many roads in the suburbs of cities have been cracked by large engineering vehicles. These cracks not only affect the urban beauty, but also will turn into potholes over time, and will indirectly cause traffic accidents in the case of poor lighting, so it is necessary to carry out grouting repair treatment on the cracks.

[0003] At present, the existing grouting devices for repairing road cracks generally use mechanical pumps to pump concrete slurries. They are large in volume and heavy in weight, not convenient for transportation and carrying, and can only fill the slurries from the cracks on the ground surface layer. It is difficult to fill the slurries into the cracks deep below the ground surface, resulting in incomplete crack repair. Summary of the Utility Model

[0004] The present disclosure relates to a portable grouting device, which solves the problems of the existing grouting devices for repairing road cracks that generally use mechanical pumps to pump concrete slurries, are large in volume and heavy in weight, not convenient for transportation and carrying, and can only fill the slurries from the cracks on the ground surface layer. It is difficult to fill the slurries into the cracks deep below the ground surface, resulting in incomplete crack repair.

[0005] In the first aspect of the present disclosure, a portable grouting device is provided, which specifically includes: a grouting outer cylinder; the grouting outer cylinder is in a vertically communicating shape, a slurry storage funnel is welded outside the grouting outer cylinder, a grouting nozzle is threadedly connected to the bottom of the grouting outer cylinder, and the slurry storage funnel is connected to the grouting nozzle through the grouting outer cylinder; the grouting nozzle is divided into different specifications according to the length of the bottom outlet end; a hollowed-out frame is installed at the top of the grouting outer cylinder through bolts, a piston is installed inside the grouting outer cylinder, and the piston is connected to the hollowed-out frame; a hand-pressing lever is connected to the top of the grouting outer cylinder, and the hand-pressing lever is connected to the piston.

[0006] Further, a slurry inlet is provided outside the grouting outer cylinder, the bottom of the slurry storage funnel is connected to the slurry inlet, the bottom of the grouting outer cylinder is connected to the grouting nozzle, the bottom outlet end of the grouting nozzle is inserted into the road crack, and a pedal is provided outside the grouting nozzle. The user steps on the pedal with both feet to fix the device by using his own body weight.

[0007] Further, the piston is slidably connected inside the grouting outer cylinder, a vertical connecting rod is provided at the top of the piston, and the vertical connecting rod slidably penetrates through the hollowed-out frame. When the piston rises to the topmost position, the piston is located above the slurry inlet, and the concrete slurry for repair inside the slurry storage funnel enters the grouting outer cylinder. When the piston falls, the piston pushes the concrete slurry inside the grouting outer cylinder to be discharged from the bottom outlet end of the grouting nozzle, so that the concrete slurry reaches the deep part of the road crack.

[0008] Furthermore, an arc-shaped baffle is provided on the top of the piston. The arc-shaped baffle is in contact with the inner wall of the grouting outer cylinder, and the inner end of the slurry inlet is in contact with the outer side of the arc-shaped baffle. When the piston drops to the bottom end, the slurry inlet can be blocked by the arc-shaped baffle.

[0009] Furthermore, a support frame and a guide frame are provided outside the grouting outer cylinder. The hand-pressing lever is rotatably connected to the support frame, and the hand-pressing lever is slidably connected inside the guide frame.

[0010] Furthermore, arc-shaped sliding holes are provided on both sides of the guide frame, and two sliders are provided outside the hand-pressing lever. The sliders are slidably connected inside the arc-shaped sliding holes. By the sliding fit of the sliders and the arc-shaped sliding holes, the rotation angle of the hand-pressing lever is limited.

[0011] Furthermore, the top end of the vertical connecting rod is located inside the hand-pressing lever. Two force-bearing sliding holes are provided outside the hand-pressing lever, and two force-bearing blocks are provided at the top end of the vertical connecting rod. The force-bearing blocks are slidably connected inside the force-bearing sliding holes. When the hand-pressing lever is rotated, the force-bearing blocks move in the force-bearing sliding holes, and the piston can be driven to move up and down by the hand-pressing lever.

[0012] The utility model provides a portable grouting device, which has the following beneficial effects:

[0013] When the utility model is in use, the user steps on the pedal with both feet to fix the device by using his own body weight. When the piston rises to the top end, the piston is located above the slurry inlet, and the concrete slurry for repair in the storage slurry funnel enters the grouting outer cylinder. When the piston drops, the piston pushes the concrete slurry inside the grouting outer cylinder to be discharged from the bottom outlet end of the grouting nozzle, so that the concrete slurry reaches the deep part of the road crack, achieving the effect of repairing and reinforcing the road crack and ensuring the driving safety of the vehicle; when the piston drops to the bottom end, the slurry inlet is blocked by the arc-shaped baffle to prevent the concrete slurry inside the storage slurry funnel from entering the grouting outer cylinder.

[0014] In addition, by the sliding fit of the sliders and the arc-shaped sliding holes, the rotation angle of the hand-pressing lever is limited. When the hand-pressing lever is rotated, the force-bearing blocks move in the force-bearing sliding holes, and the piston is driven to move up and down by the hand-pressing lever, making the operation more labor-saving. The device is small in volume and more convenient for transportation and carrying.
