Description

Technical Field

[0001] This application relates to the field of geotechnical engineering technology, and in particular to a geotechnical mixing pile. Background Technology

[0002] Mixing pile technology has been applied in various fields such as railways, ports, foundation pit support, industrial and civil buildings, docks, airports, and water conservancy. Mixing piles are a method for reinforcing saturated soft clay foundations. They utilize cement as a hardening agent, and through specialized mixing machinery, the soft soil and hardening agent are forcibly mixed deep within the foundation. The resulting physicochemical reactions between the hardening agent and the soft soil cause the soft soil to harden into a high-quality foundation with integrity, water stability, and a certain strength.

[0003] A patent document with publication number CN207700183U discloses a soil mixing pile for geotechnical engineering, comprising a baffle, a protective cover, a motor, a protective pad, a second rotating shaft, a protective plate, a rotating rod, and a slotted rod. The baffle is positioned above the first rotating shaft, with a turntable positioned below it. The protective pad is located outside the motor and below the turntable. The second rotating shaft is connected to the outside of the motor and positioned below the protective cover. The protective plate is also located outside the second rotating shaft and below the protective cover. The second rotating shaft is connected above the rotating rod, and a rotating blade is fixed to the outside of the rotating rod. The slotted rod is fixed below the rotating rod. This soil mixing pile for geotechnical engineering features a rotating blade, which is fixed to the outside of the rotating rod and has a fan-shaped structure. This design of the rotating blade can accelerate the mixing speed, simplify operation, increase the contact area, and enhance the mixing effect.

[0004] In actual use, the above devices cannot adjust the distance between the rotating rods according to the actual situation of the soil and rock mixing site. Therefore, we provide a soil and rock mixing pile. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a soil and rock mixing pile, which overcomes the deficiencies of existing technologies and aims to solve the problem that the distance between the rotating rods cannot be adjusted according to the actual situation of the soil and rock mixing site in practical use.

[0006] To achieve the above objectives, this application provides the following technical solution: a soil mixing pile for geotechnical engineering, comprising a linkage shell, a first motor fixedly installed at the top of the linkage shell, and a first mixing mechanism fixedly installed at the output end of the first motor passing through the linkage shell; the first mixing mechanism includes a first rotating shaft, the top of the first rotating shaft fixedly installed at the output end of the first motor, a first mixing roller fixedly installed at the bottom end of the first rotating shaft passing through the bottom of the linkage shell, a first bearing fixedly installed on the outer surface of the first rotating shaft, electric push rods fixedly installed on both sides of the first bearing, and a second rotating mechanism fixedly installed at the telescopic end of the electric push rods. The second rotating mechanism includes a second bearing, which is fixedly installed on the telescopic end of the electric push rod. A second rotating shaft is fixedly installed on the inner ring of the second bearing. A second motor is fixedly installed on the top of the second rotating shaft through the top of the linkage housing. A second stirring roller is fixedly installed on the bottom of the second rotating shaft through the bottom of the linkage housing. A base plate is provided at the bottom of the second stirring roller. Two sets of slide rails are provided on the top of the linkage housing on both sides of the first motor. Two sets of sliders are slidably connected to the sliding ends of the two sets of slide rails. The tops of the two sets of sliders are fixedly installed to the bottom of the base plate. A groove matching the second stirring roller is provided at the bottom of the linkage housing.

[0007] By adopting the above technical solution, the distance between the second mixing roller and the first mixing roller is adjusted according to the actual situation of the soil and rock mixing site. The position of the second bearing is changed by driving the electric push rod. During movement, the top of the second rotating shaft drives the base plate to slide in the slide rail, and the bottom of the second rotating shaft drives the second bearing to slide in the slide groove. This allows the second motor and the second bearing to move synchronously with the second rotating shaft. After adjusting the distance between the second mixing roller and the first mixing roller to a suitable distance, the first motor drives the first mixing roller to rotate, and the second motor drives the second mixing roller to rotate, thus mixing the soil and rock. By adjusting the distance between the second mixing roller and the first mixing roller, it is possible to adjust the distance according to the actual situation of the soil and rock mixing site, thereby improving the practicality of use.

[0008] As a preferred technical solution of this application, connecting blocks are fixedly installed on both sides of the linkage housing, a hydraulic cylinder is fixedly installed at the bottom of the connecting blocks, and a base is fixedly installed at the bottom end of the hydraulic cylinder.

[0009] By adopting the above technical solution, when this mixing pile is mixing, the hydraulic cylinder is activated, which drives the linkage shell to rise or fall, causing the first mixing roller and the second mixing roller to rise or fall. This allows the mixing pile to mix areas where the soil is unevenly mixed, which is beneficial for automatically adjusting the mixing pile under the action of the hydraulic cylinder and reducing the workload of workers.

[0010] As a preferred technical solution of this application, both the first motor and the second motor are equipped with motor protective shells, and a shock-absorbing layer is fixedly installed inside the motor protective shells.

[0011] By adopting the above technical solution, the motor protective shell 13 improves the protection effect on the first motor 2 and the second motor. At the same time, the shock-absorbing layer 14 can play a buffering role when the first motor 2 and the second motor are working, thereby increasing the service life of the first motor 2 and the second motor.

[0012] As a preferred technical solution of this application, several sets of stirring blades are fixedly installed on the outer surfaces of both the first stirring roller and the second stirring roller.

[0013] By adopting the above technical solution, the mixing blade 15 assists the first mixing roller and the second mixing roller in mixing, which helps to make the mixing more uniform when the mixing pile rotates.

[0014] As a preferred technical solution of this application, slotted rods are fixedly installed at the bottom ends of both the first stirring roller and the second stirring roller.

[0015] By adopting the above technical solution, the slotted rod 16 facilitates the smoother and faster insertion of the first and second mixing rollers into the soil for mixing.

[0016] As a preferred technical solution of this application, the bottom end of the base is fixedly connected with several sets of resistance-increasing strips.

[0017] By adopting the above technical solution, the friction between the base and the contact surface is increased by adding resistance strips, thereby improving the stability of this mixing pile during operation.

[0018] The beneficial effects of this application are:

[0019] 1. Based on the actual conditions of the soil and rock mixing site, adjust the distance between the second mixing roller and the first mixing roller. The position of the second bearing is changed by an electric push rod. During movement, the top of the second rotating shaft drives the base plate to slide within the slide rail, and the bottom of the second rotating shaft drives the second bearing to slide in the slide groove. This allows the second motor and the second bearing to move synchronously with the second rotating shaft. After adjusting the distance between the second and first mixing rollers to a suitable level, the first motor drives the first mixing roller to rotate, and the second motor drives the second mixing roller to rotate, thus mixing the soil and rock. Adjusting the distance between the second and first mixing rollers allows for adjustments based on the actual conditions of the soil and rock mixing site, improving its practicality during use.

[0020] 2. When this mixing pile is in operation, the hydraulic cylinder is activated, which drives the linkage shell to rise or fall, causing the first and second mixing rollers to rise or fall. This allows the mixing pile to mix areas where the soil is unevenly mixed. It also helps to automatically adjust the mixing pile under the action of the hydraulic cylinder, reducing the workload of workers. Attached Figure Description

The second bearing 401 is fixedly installed at the telescopic end of the electric push rod 303. The inner ring of the second bearing 401 is fixedly installed with the second rotating shaft 402. The top of the second rotating shaft 402 passes through the top of the linkage housing 1 and is fixedly installed with the second motor 403. The bottom of the linkage housing 1 is fixedly installed with the second stirring roller 404. The bottom of the second stirring roller 404 is provided with a base plate 7. The top of the linkage housing 1 is provided with two sets of slide rails 5 on both sides of the first motor 2. The sliding ends of the two sets of slide rails 5 are slidably connected with two sets of sliders 6. The tops of the two sets of sliders 6 are fixedly installed with the bottom ends of the base plate 7. The bottom of the linkage housing 1 is provided with a groove 8 that matches the second stirring roller 404. The periphery of the first motor 2 and the second motor 403 are both equipped with motor protective shells 13, and the inside of the motor protective shells 13 is fixedly installed with a shock-absorbing layer 14.

[0027] By adjusting the distance between the second mixing roller 404 and the first mixing roller 304 according to the actual situation of the soil mixing site when using the soil mixing pile for geotechnical engineering, the position of the second bearing 401 is changed by the electric push rod 303. During the movement, the top of the second rotating shaft 402 drives the base plate 7 to slide in the slide rail 5, and the bottom of the second rotating shaft 402 drives the second bearing 401 to slide in the slide groove 8, so that the second motor 403 and the second bearing 401 move synchronously with the second rotating shaft 402. After adjusting the distance between the second mixing roller 404 and the first mixing roller 304 to a suitable distance, the first motor 2 drives the first mixing roller 304 to rotate, and the second motor 403 drives the second mixing roller 404 to rotate, thus mixing the soil and rock. By adjusting the distance between the second mixing roller 404 and the first mixing roller 304, it is beneficial to adjust the actual situation of the soil mixing site, thus improving the practicality during use. The motor protective shell 13 improves the protection of the first motor 2 and the second motor 403. At the same time, the shock-absorbing layer 14 can buffer the first motor 2 and the second motor 403 when they are working, thereby increasing the service life of the first motor 2 and the second motor 403.

[0028] Reference Figure 1-3Connecting blocks 9 are fixedly installed on both sides of the linkage housing 1. A hydraulic cylinder 10 is fixedly installed at the bottom of the connecting blocks 9, and a base 11 is fixedly installed at the bottom end of the hydraulic cylinder 10. Several sets of friction-increasing strips 12 are fixedly connected to the bottom end of the base 11. When this mixing pile is mixing, the hydraulic cylinder 10 is activated, which drives the linkage housing 1 to rise or fall, causing the first mixing roller 304 and the second mixing roller 404 to rise or fall. This allows the mixing pile to mix areas where the soil is unevenly mixed, which is beneficial for automatically adjusting the mixing pile under the action of the hydraulic cylinder 10, reducing the workload of workers. The friction-increasing strips 12 increase the friction between the base 11 and the contact surface, improving the stability of the mixing pile during operation.

[0029] Reference Figure 1 Several sets of mixing blades 15 are fixedly installed on the outer surfaces of both the first mixing roller 304 and the second mixing roller 404. A slotted rod 16 is fixedly installed at the bottom end of both the first mixing roller 304 and the second mixing roller 404. The mixing blades 15 assist the mixing of the first mixing roller 304 and the second mixing roller 404, which helps to make the mixing more uniform when the mixing pile rotates. The slotted rod 16 facilitates the smoother and faster insertion of the first mixing roller 304 and the second mixing roller 404 into the soil for mixing.

[0030] Working principle: Based on the actual conditions of the soil mixing site, the distance between the second mixing roller 404 and the first mixing roller 304 is adjusted. The position of the second bearing 401 is changed by the electric push rod 303. During movement, the top of the second rotating shaft 402 drives the base plate 7 to slide within the slide rail 5, and the bottom of the second rotating shaft 402 drives the second bearing 401 to slide at the slide groove 8. This causes the second motor 403 and the second bearing 401 to move synchronously with the second rotating shaft 402. After adjusting the distance between the second mixing roller 404 and the first mixing roller 304 to a suitable level, the first motor 2 drives the first mixing roller 304... The second motor 403 drives the second mixing roller 404 to rotate, mixing the soil and rock. By adjusting the distance between the second mixing roller 404 and the first mixing roller 304, it is possible to adjust the actual position of the soil and rock mixing site, improving its practicality. When this mixing pile is mixing, the hydraulic cylinder 10 is activated, which drives the linkage housing 1 to rise or fall, causing the first mixing roller 304 and the second mixing roller 404 to rise or fall, so that this mixing pile can mix areas where the soil is unevenly mixed. This is beneficial for automatically adjusting this mixing pile under the action of the hydraulic cylinder 10, reducing the workload of workers.

[0031] Among them, the motor protective shell 13 improves the protection effect of the first motor 2 and the second motor 403. At the same time, the shock-absorbing layer 14 can buffer the first motor 2 and the second motor 403 when they are working, increasing the service life of the first motor 2 and the second motor 403. The stirring blade 15 assists the stirring of the first stirring roller 304 and the second stirring roller 404, which is conducive to more uniform stirring when the mixing pile rotates.

[0032] Meanwhile, the slotted rod 16 facilitates the smoother and faster insertion of the first mixing roller 304 and the second mixing roller 404 into the soil for mixing.

[0033] In addition, the friction between the base 11 and the contact surface is increased by the friction-increasing strip 12, thereby improving the stability of the mixing pile during operation.
