Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, specifically to a road crack filling and pressure grouting device. Background Technology

[0002] After prolonged use, urban roads develop narrow cracks due to thermal expansion and contraction and the pressure of passing vehicles. If these cracks are not repaired promptly, they will worsen and eventually render the road impassable. Currently, repairs are primarily done manually or using mechanical equipment. Manual repairs are typically used for a small number of cracks, while mechanical equipment is employed when the cracks are numerous and large. However, mechanical repair methods have drawbacks, including poor grouting results due to varying crack depths and the grout solidifying over time. For example, the utility model patent with authorization announcement number CN220685740U discloses a road crack filling pressure injection device, which includes a material mixing box. The right end of the material mixing box is connected to a placement plate, and a pressure boosting component is provided on the placement plate. The output end of the pressure boosting component is connected to a material conveying pipe. Two sets of support plates are symmetrically connected to the right end of the placement plate. A support frame is fixedly installed on the two sets of support plates. A bidirectional threaded rod is rotatably provided on the support frame. A handwheel is fixedly connected to the front end of the bidirectional threaded rod. A U-shaped handle is slidably provided on the fixed frame through a sliding hole. A limiting rack is fixedly connected to the U-shaped handle. Two sets of springs are sleeved on the U-shaped handle. The two ends of each set of springs are connected to the fixed frame and the limiting rack, respectively. Both sets of transmission plates are provided with limiting blocks, and the two sets of limiting blocks are engaged with the limiting rack, which can make the grouting pipe length adjustment continuous and avoid the situation of the grouting pipe being too long or too short, thus improving practicality. However, this device makes the grout maintain good uniformity for a long time. Utility Model Content

[0003] The purpose of this utility model is to provide a road crack filling pressure injection device. This injection device can not only inject grout for cracks of different depths and improve the grouting quality, but also maintain the temperature and fluidity of the grout and avoid the phenomenon of grout solidification. It is highly practical.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A road crack sealing and pressurized grouting device includes a support frame and a cylinder fixedly installed on the support frame. A heating plate and a stirring mechanism are installed inside the cylinder. The heating plate heats and keeps the grout inside the cylinder at a certain temperature, and the stirring mechanism stirs the grout inside the cylinder. Multiple grouting pipes are installed at the bottom of the cylinder. A base is fixedly installed on the outside of the cylinder. Two adjustable moving mechanisms are installed on the base and the support frame, and the position of the cylinder is moved by the two adjustable moving mechanisms.

[0005] Preferably, a cylinder cover is detachably installed on the top of the cylinder, and a grouting hole is provided on the cylinder cover.

[0006] Preferably, the stirring mechanism includes a drive motor mounted on the support frame, a drive shaft powered to the output end of the drive motor, a transmission cylinder mounted on the drive shaft, and a connecting column mounted on the transmission cylinder. One end of the drive shaft passes through the cylinder and is located inside the cylinder. Multiple stirring columns are installed on the drive shaft and the connecting column. When the drive motor is powered on and drives the drive shaft to rotate, the multiple stirring columns stir the slurry inside the cylinder.

[0007] Preferably, the support frame and the base are fixedly connected by a support plate.

[0008] Preferably, the adjustable moving mechanism includes a connecting seat fixedly mounted on the support frame, an upper connecting shaft disposed on the connecting seat, a connecting frame hingedly mounted on the upper connecting shaft, a roller mounted on the connecting frame via a lower connecting shaft, and a linear drive fixedly mounted on the base. A sliding groove is provided on the connecting frame, and one end of the linear drive is movably connected in the sliding groove. When the linear drive extends or retracts, it drives the connecting frame to swing around the upper connecting shaft.

[0009] Preferably, three linear drive elements are provided in one of the adjustable moving mechanisms; the linear drive elements are electric push rods or cylinders.

[0010] Preferably, a grouting pump is installed on the grouting pipe, and the grouting operation is carried out by controlling the corresponding grouting pipe through the grouting pump.

[0011] In this invention, the heating plate heats and maintains the temperature of the grout inside the cylinder, preventing solidification due to excessively low temperatures. The stirring mechanism continuously agitates the grout within the cylinder, ensuring its uniformity and preventing a viscous bottom and thin top caused by settling, thus guaranteeing the grouting effect. The adjustable moving mechanism allows the entire device to be moved along the crack direction under external force, and also adjusts the distance between the grouting pipe and the top of the crack, adapting to grouting operations at different crack depths and demonstrating strong adaptability.

[0013] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 , Figure 2 , Figure 3 and Figure 4 The road crack sealing and pressurized grouting device shown includes a support frame 6 and a cylinder 1 fixedly mounted on the support frame 6. A through hole is provided in the middle of the support frame 6, through which the cylinder 1 passes. A detachable cap 2 is installed on the top of the cylinder 1, and a grouting hole is provided on the top of the cap 2, through which grout can be injected into the cylinder 1. For asphalt road repair, the grout is asphalt. Of course, for cement road repair, cement mortar can also be used. The grouting hole is sealed with a sealing plug to ensure the airtightness of the cylinder 1. A vent hole is provided on the sealing plug, through which gas enters the cylinder 1 during grouting operations.

[0014] A heating plate 3 is installed inside the cylinder 1. The heating plate 3 heats and keeps the slurry inside the cylinder 1 warm, preventing the slurry from cooling and solidifying due to low temperature.

[0015] A stirring mechanism 4 is installed inside the cylinder 1. The stirring mechanism 4 stirs the slurry inside the cylinder 1 to avoid the phenomenon of thick slurry at the bottom and thin slurry at the top caused by sedimentation, thus ensuring the grouting effect. The stirring mechanism 4 includes a drive motor 401 fixedly installed on the support frame 6, a drive shaft 402 connected to the output end of the drive motor 401 via a coupling or key, a transmission cylinder 403 fixedly installed on the drive shaft 402, and a connecting column 404 installed on the transmission cylinder 403. Two connecting columns 404 are symmetrically arranged. One end of the drive shaft 402 is sealed and passes through the cylinder 1 and is located inside the cylinder 1. Multiple stirring columns 405 are installed on the drive shaft 402 and the connecting column 404. When the drive motor 401 is energized and drives the drive shaft 402 to rotate, the rotation of the drive shaft 402 and the connecting column 404 drives the multiple stirring columns 405 to stir the slurry inside the cylinder 1. To further improve the smoothness of the rotation of the drive shaft 402, one cantilevered end of the drive shaft 402 is connected to the cylinder 1 or the support frame 6 via a bearing.

[0016] Multiple grouting pipes 5 are installed at the bottom of the cylinder 1. A grouting pump is installed on each grouting pipe 5. The grouting operation is controlled by starting and stopping the grouting pump. A single grouting pipe 5 can be used for grouting, or multiple grouting pipes 5 can be used for grouting simultaneously.

[0017] A base 8 is fixedly installed on the outside of the cylinder 1. The base 8 is located below the support frame 6. The support frame 6 and the base 8 are fixedly connected by the support plate 7 to form a rectangular frame structure, which improves the stability of the cylinder 1 installation and avoids overturning.

[0018] Adjustable moving mechanisms 9 are installed on the base 8 and the support frame 6. Two adjustable moving mechanisms 9 are arranged opposite each other, and the position and height of the cylinder 1 are adjusted through the two adjustable moving mechanisms. The adjustable moving mechanism 9 includes a connecting seat 901 fixedly installed on the support frame 6, an upper connecting shaft 902 set on the connecting seat 901, a connecting frame 903 hinged to the upper connecting shaft 902, a roller 905 installed on the connecting frame 903 through a lower connecting shaft 904, and a linear drive 907 fixedly installed on the base 8. A sliding groove is provided on the connecting frame 903, and one end of the linear drive 907 is movably connected in the sliding groove through a limiting shaft 906. When the linear drive 907 is energized and extends or retracts, it drives the connecting frame 903 to swing around the upper connecting shaft 902, thereby realizing the height adjustment between the bottom of the cylinder 1 and the ground. In use, the device is pushed to move along the length of the crack. Of course, an electric roller can also be used instead of the roller 905, and the device can be automatically moved by a controller.

[0019] In a preferred embodiment, three linear actuators 907 are provided in an adjustable moving mechanism 9; the linear actuators 907 are electric push rods or cylinders, and the three linear actuators 907 move synchronously.

[0020] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
