Description

Technical Field

[0001] This utility model relates to the field of grouting technology in geotechnical engineering, specifically to a grouting device for geotechnical engineering. Background Technology

[0002] Grouting devices in geotechnical engineering are indispensable equipment in grouting construction. They deliver solid or liquid grouting materials into holes or defects in the ground or structure in a certain way to fill voids, reinforce soil or rock, and improve their mechanical properties. However, how to adjust the guide cylinder according to the position of the grouting hole to ensure that the two are properly connected and to avoid gaps at the connection that could lead to grouting leakage is a problem that urgently needs to be solved.

[0003] A search revealed that CN214887216U discloses a grouting device for geotechnical engineering, relating to the field of geotechnical engineering construction technology. This invention includes a base, a mixing tank fixedly mounted on the upper surface of the base, a motor fixedly mounted on the upper surface of the mixing tank, a feed pipe fixedly mounted on the upper surface of the mixing tank, a rotating shaft fixedly connected to the output end of the motor, several rotating paddles vertically welded to the circumference of the rotating shaft, a discharge pipe fixedly connected to the bottom of the circumference of the mixing tank, a pump connected to the other end of the discharge pipe, a guide hose connected to one side of the pump, and a guide cylinder connected to one end of the guide hose. This invention connects the mixing tank, pump, and guide cylinder using the discharge pipe and guide hose, utilizing the mixing tank to mix the grout before conveying it to the guide cylinder, shortening the grouting process, simplifying the procedure, reducing costs, facilitating operation, and increasing efficiency. The detachable connection structure facilitates maintenance and cleaning of the guide hose and discharge pipe, extending their service life.

[0004] The above-mentioned geotechnical engineering grouting device involves moving the base to the target position via casters, then sequentially tightening each bolt to raise the base plate until the casters are off the ground, ultimately improving the stability of the base plate.

[0005] In this design, the guide cylinder located on one side of the base plate will rise synchronously with the above steps, resulting in a certain distance between the bottom of the guide cylinder and the grouting hole. Since the guide cylinder has a fixed length, this design requires the bolts to be tightened again to make the base plate move the guide cylinder down until the guide cylinder connects with the grouting hole. This ultimately leads to the problem of time-consuming and labor-intensive docking process between the guide cylinder and the grouting hole. Utility Model Content

[0006] This utility model proposes a grouting device for geotechnical engineering, which solves the problem in the prior art that the bottom plate needs to be tightened again to move the guide cylinder down until the guide cylinder connects with the grouting hole, which ultimately leads to a time-consuming and labor-intensive connection process between the guide cylinder and the grouting hole.

[0007] The technical solution of this utility model is as follows: a grouting device for geotechnical engineering, including a grouting assembly, the grouting assembly including an upper pipe and a lower pipe, the grouting assembly also including a corrugated pipe, the upper end of the corrugated pipe being fixedly connected to the upper pipe, the lower end of the corrugated pipe being fixedly connected to the lower pipe, a telescopic component being provided on the outside of the upper pipe that can drive the lower pipe to telescopically move at the bottom of the upper pipe, and a steering component being provided on the outside of the lower pipe that can drive the lower pipe to adjust its angle at the bottom of the upper pipe.

[0008] Preferably, the telescopic assembly further includes a side seat, which is fixedly connected to the outside of the upper tube. The telescopic assembly also includes a forward and reverse motor, which is fixedly installed inside the side seat, and a threaded rod is fixedly connected to the output end of the forward and reverse motor.

[0009] Preferably, the telescopic assembly further includes a ring seat, which is threadedly connected to the outside of the threaded rod. The telescopic assembly also includes two sets of vertical support rods, which are symmetrically fixedly connected to the bottom of the ring seat.

[0010] Preferably, the steering assembly includes a cylinder, which is fixedly installed on the outside of one of the vertical support rods. A sleeve plate is fixedly connected to the outside of the cylinder's telescopic end, and a toothed plate is fixedly connected to the outside of the sleeve plate. A limit slip is also fixedly connected to the side of the toothed plate.

[0011] Preferably, the steering assembly further includes two sets of rotating shafts, which are rotatably connected to the middle of each vertical support rod. The inner side of each rotating shaft is fixedly connected to the outer side of the lower pipe. The steering assembly also includes a gear, which is fixedly connected to the outer side of one of the rotating shafts. The gear contacts the toothed plate and is engaged in a transmission connection.

[0012] Preferably, the telescopic assembly further includes a limiting groove, which is formed on the outside of one of the vertical support rods, and the limiting groove corresponds to the position of the limiting slide buckle.

[0013] Preferably, the grouting assembly further includes a sealing ring and a threaded groove, which are fixedly connected to the bottom outer side of the lower pipe.

[0014] Preferably, the grouting assembly further includes a grouting replacement head, which is threadedly connected to a threaded groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention features a telescopic assembly and a bellows at the connection between the upper and lower connecting pipes. When adjusting the lower connecting pipe and the grouting replacement head to align with the grouting hole, a forward and reverse motor can be activated based on the distance between the grouting replacement head and the grouting hole. This causes the output of the forward and reverse motors to drive the threaded rod to rotate, which in turn causes the ring seat threaded to the outside of the threaded rod to drive the vertical support rod and the lower connecting pipe located between the two vertical support rods to move synchronously until the grouting replacement head at the bottom of the lower connecting pipe completes the alignment with the grouting hole. Simultaneously, a cylinder is activated based on the angle difference between the lower connecting pipe and the grouting hole. The telescopic end of the cylinder drives the toothed plate to move horizontally outside the vertical support rod, which in turn causes the gear on one side of the meshing toothed plate to drive the lower connecting pipe to rotate within a certain range at the bottom of the upper connecting pipe until the lower connecting pipe aligns with the grouting hole. Compared to the prior art, this design can quickly adjust the grouting assembly to align with the grouting hole using the telescopic and steering assemblies. Attached Figure Description

[0026] This design solves the problem in the existing technology that requires re-tightening the bolts to move the bottom plate and guide cylinder downwards until the guide cylinder connects with the grouting hole, which ultimately leads to a time-consuming and labor-intensive connection process between the guide cylinder and the grouting hole.

[0027] Please see Figure 2 The telescopic assembly 2 also includes a side seat 21, which is fixedly connected to the outside of the upper tube 11.

This design also facilitates the connection of the lower pipe 13 and the grouting replacement head 14 with the grouting hole.

[0030] Please see Figure 3 and Figure 4 and Figure 5 The steering assembly 3 includes a cylinder 31, which is fixedly installed on the outside of one of the vertical support rods 24. A sleeve plate 32 is fixedly connected to the outside of the telescopic end of the cylinder 31. A toothed plate 33 is fixedly connected to the outside of the sleeve plate 32.

[0037] The working principle and usage process of this utility model are as follows:

[0038] The staff first selects a grouting replacement head 14 that matches the diameter of the grouting hole, and then fixes the grouting replacement head 14 to the threaded groove 132 of the lower pipe 13 through the internal thread.

[0039] Then, the upper pipe 11 of the grouting assembly 1 is connected to the grouting mechanism;

[0040] After the above steps are completed, the forward and reverse motor 22 can be started first, so that the output end of the forward and reverse motor 22 drives the threaded rod 221 to rotate. Then, the ring seat 23 threaded to the outside of the threaded rod 221 drives the vertical support rod 24 and the lower pipe 13 located between the two vertical support rods 24 to move synchronously until the grouting replacement head 14 at the bottom of the lower pipe 13 completes the docking work with the grouting hole. At the same time, the cylinder 31 is started according to the angle difference between the lower pipe 13 and the grouting hole. The extension end of the cylinder 31 drives the toothed plate 33 to move horizontally outside the vertical support rod 24. Then, the gear 34 on one side of the meshing toothed plate 33 drives the lower pipe 13 to rotate within a certain range at the bottom of the upper pipe 11 until the lower pipe 13 is aligned with the grouting hole.
