Description

Technical Field

[0001] The utility model relates to a grouting device, in particular to a grouting device for bridges and tunnels. Background Technique

[0002] Grouting is a common reinforcement technique. By injecting solidifying materials (such as cement, lime or other chemical substances) into the cracks and pores in the foundation rock and soil, it aims to prevent foundation leakage and enhance the integrity, strength and stiffness of the rock and soil. The grouting device is a special equipment designed for such projects.

[0003] When the traditional grouting device is performing grouting operations, the grouting head needs to be inserted into the insertion pipe pre-installed in the tunnel crack to inject the material into the crack through the insertion pipe. However, under complex terrain conditions such as tunnels, due to the semi-circular shape of the tunnel and uneven crack distribution, there are many inconveniences in the traditional grouting method. During the actual operation process, the operator must hold the heavy grouting head to find and insert the insertion pipes with different positions. This process is not only laborious, but also when the insertion pipe is at a high position, an additional lifting platform is needed for assistance, which undoubtedly increases the construction difficulty and cost and reduces the work efficiency.

[0004] Based on this, in order to solve the above-mentioned technical defects, a grouting device for bridges and tunnels is now proposed. Content of the Utility Model

[0005] In order to overcome the shortcoming that the traditional grouting device needs to hold the grouting head to complete the connection with the insertion pipe in the tunnel crack for grouting, which is rather troublesome to operate, the technical problem of the utility model is: to provide a grouting device for bridges and tunnels.

[0006] The technical solution is: a grouting device for bridges and tunnels, including a grouting machine, a controller, a grouting pump, a connecting pipe, a grouting head, a base, a first electric push rod, a lifting plate, a second electric push rod, a first motor and a rotating frame. The left side of the grouting machine is connected with the grouting pump, the connecting pipe is connected to the grouting pump, the left side of the chassis of the grouting machine is connected with the base, the first electric push rod is installed at the rear side of the top of the base, the lifting plate is connected to the telescopic rod of the first electric push rod, the second electric push rod is installed on the lifting plate, the first motor is installed on the telescopic rod of the second electric push rod, the rotating frame is connected to the output shaft of the first motor, the grouting head is installed at the tail end of the connecting pipe, the grouting head passes through the rotating frame and is fixedly connected to the rotating frame, and the grouting pump, the first electric push rod, the second electric push rod and the first motor are all electrically connected to the controller.

[0007] Further explanation, it also includes a column. The column is provided on the left side of the top of the base, and the connecting pipe is wound on the column.

[0008] Further description, it also includes universal wheels, and the bottom of the base and the bottom of the grouting machine chassis are both rotatably connected with multiple universal wheels.

[0009] Further description, it also includes a fixed block and a camera. The middle part of the grouting head is connected to the fixed block, and the camera is installed on the upper side of the fixed block. The camera is electrically connected to the controller.

[0010] Further explanation: it also includes a spring and a buffer frame. The left end of the grouting head is slidingly connected to the buffer frame. A spring is connected between the buffer frame and the fixed block. The spring is sleeved on the grouting head. A slot with a diameter larger than the diameter of the grouting head pipe mouth is opened in the middle of the buffer frame.

[0011] Further explanation: it also includes a rotating cylinder, a lighting lamp, a second motor and a gear. The rotating cylinder is rotatably connected to the right side of the fixed block, a lighting lamp is installed on the upper side of the rotating cylinder, and a second motor is installed on the right side of the lower part of the fixed block. The output shaft of the second motor is connected to a gear. A plurality of tooth grooves are evenly arranged on the outside of the rotating cylinder, and the gears are engaged with the tooth grooves.

[0012] Beneficial effects: 1. By configuring the first electric push rod, the second electric push rod and the first motor, the height, horizontal direction and rotation angle of the grouting head can be accurately adjusted. This not only enables the equipment to adapt to the various grouting point requirements inside the tunnel, but also realizes automatic adjustment, thereby avoiding the need for manual holding of the grouting head and the plug-in pipe;

[0013] 2. Combining the use of lighting and cameras, the lighting provides the necessary fill light function, while the camera is responsible for recording the movement trajectory of the grouting head, which helps the operator complete the plugging task more accurately and quickly. In addition, the design of the lighting allows its angle to be adjusted to ensure that it can provide the best fill light effect regardless of the position, thereby ensuring that the clarity of the camera's field of view is not affected.

The left side of the chassis of the grouting machine 1 is connected to the base 5, and a plurality of universal wheels 6 are rotatably connected to the bottom of the base 5 and the bottom of the chassis of the grouting machine 1. The first electric push rod 7 for adjusting the height of the grouting head 4 is installed on the rear side of the top of the base 5 by bolts. The lifting plate 8 is connected to the telescopic rod of the first electric push rod 7, and the second electric push rod 9 for adjusting the horizontal position of the grouting head 4 is installed on the lifting plate 8. The first motor 10 for adjusting the angle of the grouting head 4 is installed on the telescopic rod of the second electric push rod 9 by bolts. The rotating frame 11 is connected to the output shaft of the first motor 10. The tail end of the connecting pipe 3 is provided with a grouting head 4, and the grouting head 4 passes through the rotating frame 11 and is fixedly connected to the rotating frame 11. The grouting pump 2, the first electric push rod 7, the second electric push rod 9 and the first motor 10 are all electrically connected to the controller 101.

[0021] As Figure 3 shown, it further includes a fixing block 12, a camera 13, a spring 14 and a buffer frame 15. The middle of the grouting head 4 is connected to the fixing block 12, the camera 13 is installed on the upper side of the fixing block 12, and the camera 13 is electrically connected to the controller 101. The left end of the grouting head 4 is slidably connected to the buffer frame 15, a spring 14 is connected between the buffer frame 15 and the fixing block 12, the spring 14 is sleeved on the grouting head 4, and a notch with a diameter larger than the pipe orifice diameter of the grouting head 4 is opened in the middle of the buffer frame 15.

[0022] As Figure 4 shown, it further includes a rotating cylinder 16, a lighting lamp 17, a second motor 18 and a gear 19. The right side of the fixed block 12 is rotatably connected to the rotating cylinder 16. The lighting lamp 17 is installed on the upper side of the rotating cylinder 16. The second motor 18 is installed on the lower right side of the fixed block 12. The output shaft of the second motor 18 is connected to the gear 19. A plurality of tooth grooves are evenly formed on the outer side of the rotating cylinder 16, and the gear 19 is engaged with the tooth grooves.

[0023] When grouting a cracked bridge tunnel, it is first necessary to determine the grouting points and pre-install insertion pipes at each grouting point. Subsequently, move this device to the designated position in the tunnel through the universal wheels 6 it is equipped with. After reaching the destination, connect the camera 13 to the operator's mobile terminal through the controller 101, and then the operator can view the images captured by the camera 13 in real time. Next, operate the controller 101 to start the grouting pump 2 to ensure continuous stirring and mixing of the materials to prevent them from settling and solidifying. According to the position of the insertion pipe, align the grouting head 4 with the insertion pipe. Then, operate the controller 101 to start the first electric push rod 7, so that the telescopic rod of the first electric push rod 7 extends, driving the lifting plate 8 and the components thereon to rise, thereby moving the grouting head 4 upward. When it is necessary to adjust the height of the grouting head 4, it can be achieved by controlling the telescopic movement of the telescopic rod of the first electric push rod 7. If it is necessary to adjust the horizontal position of the grouting head 4, start the second electric push rod 9, so that the telescopic rod of the second electric push rod 9 extends or retracts, driving the first motor 10 and the rotating frame 11 to move left and right, and then driving the grouting head 4 to move left and right. When it is necessary to adjust the angle of the grouting head 4, start the first motor 10, and drive the rotating frame 11 to rotate through its output shaft to adjust the angle of the grouting head 4. Through the above steps, the height, left and right positions, and angle of the grouting head 4 can be flexibly adjusted according to the actual position of the insertion pipe. After the position of the grouting head 4 is adjusted in place, turn off the relevant equipment, and turn on the lighting lamp 17 through the controller 101 to provide necessary lighting. By viewing the images transmitted by the camera 13, accurately confirm whether the grouting head 4 is aligned with the insertion pipe and make fine adjustments. Then, operate the controller 101 to control the relevant equipment to drive the grouting head 4 to move, so that the buffer frame 15 passes through the insertion pipe through the notch and contacts the tunnel wall. At this time, the spring 14 will be compressed. As the grouting head 4 continues to move forward until it is completely docked with the insertion pipe, the buffer frame 15 plays a role in buffering the grouting head 4. After the insertion is completed, turn off the relevant equipment and start the grouting pump 2 to transport the materials in the grouting machine 1 to the connecting pipe 3 and enter the insertion pipe through the grouting head 4, finally filling the tunnel crack and completing the grouting operation. After the grouting is completed, turn off the grouting pump 2, and control the grouting head 4 to withdraw from the insertion pipe through the equipment, and the spring 14 will reset accordingly, causing the buffer frame 15 to rebound and reset. For subsequent grouting points, repeat the above operations. In addition, the angle of the lighting lamp 17 can also be adjusted according to the position of the insertion pipe. Operate the controller 101 to start the second motor 18, and drive the gear 19 to rotate through its output shaft. The gear 19 then drives the rotating cylinder 16 and the lighting lamp 17 to rotate to adjust the lighting lamp 17 to the most suitable angle. After the adjustment is completed, turn off the second motor 18.
