Description

Technical Field

[0001] The utility model relates to the technical field of grouting machine devices, and more specifically to a high-rise foundation grouting reinforcement machine. Background Art

[0002] Foundation grouting is a foundation treatment technology that can increase the bearing capacity and stability of the foundation, making the foundation more suitable for supporting buildings or other structures. It can fill the gaps and cracks in the strata and improve the overall density and consistency of the soil. At the same time, foundation grouting can reduce the settlement of the soil, especially when the foundation is uneven or loose.

[0003] During the grouting process, according to the design requirements, holes are drilled in the foundation, and holes of a certain depth are usually selected for grouting. In order to achieve a better grouting effect, the grouting head is usually inserted into a suitable depth. Since the grouting port is downward, the grouting port needs to be suspended and fixed at a certain height to prevent the grouting port from touching the bottom of the borehole and affecting the grouting effect. The traditional device requires manual suspension and fixation of the grouting head. This method causes the grouting pipe to easily fall over during grouting, making it unstable.

A grouting head 9 is fixedly installed at the lower end of the grouting pipe 6, and a fixing plate 5 is fixedly installed in the middle of the outer side of the grouting pipe 6. A pair of adjusting rings 4 are symmetrically arranged on the left and right sides of the upper end of the fixing plate 5.

A main support plate 7 is fixedly installed at the lower end of the adjusting screw rod 3 on both sides, and four auxiliary support pieces 8 are rotatably installed on the upper periphery of the main support plate 7.

[0035] A mixing blade 25 is fixedly installed on the outer side of the middle of the main stirring shaft 16. The mixing blade 25 is composed of multiple sections of metal stirring blades. The main stirring shaft 16 drives the mixing blade 25 to rotate, which can mix the internal mud and prevent the cement slurry from solidifying.

[0036] A square feeding trough is provided at the front upper end of the main mixing box 15, and the operator can pour cement slurry into the main mixing box 15 through the square feeding trough;

[0037] A transmission belt is arranged between the secondary drive disc 14 and the secondary transmission disc 13, and a transmission belt is arranged between the main drive turntable 19 and the linkage turntable 17 and the conveying turntable 18 and the linkage turntable 17. The linkage turntable 17 can be driven to rotate by the main drive turntable 19, and the linkage turntable 17 drives the conveying turntable 18 to rotate. The main stirring shaft 16 in the middle of the linkage turntable 17 drives the secondary transmission disc 13 to rotate through the secondary drive disc 14;

[0038] The secondary stirring rod 21 is located at one end of the secondary stirring box 11 and is fixedly mounted with a secondary stirring blade 22 that matches the inner cavity of the secondary stirring box 11. The secondary stirring blade 22 can pump the internal slurry out from the discharge pipe 1 to ensure that the slurry is evenly mixed and pumped out;

[0039] The rotation limiter 501 is a circular "L"-shaped limiter structure. The lower end of the adjusting ring 4 is opened and closed with a rotation groove corresponding to the rotation limiter 501. The adjusting ring 4 can ensure free rotation while not being separated from the fixing plate 5.

[0040] A pair of stabilizing screw rods 10 are fixedly installed on the front and rear sides of the upper end of the main support plate 7. A circular through groove corresponding to the main support plate 7 is opened on the upper side of the fixed plate 5. The stabilizing screw rods 10 can play a certain stabilizing role in the process of adjusting the main support plate 7 up and down;

[0041] The outer wall of the discharge pipe 1 is fixedly mounted with a spiral blade 24 that matches the diameter of the material conveying pipe 23 . The spiral blade 24 can pressurize the internal mortar and drive it into the secondary mixing box 11 .

[0042] The working principle of the utility model is as follows: the operator fills the concrete slurry into the main mixing box 15, the servo motor 20 drives the main driving turntable 19 to rotate, a transmission belt is arranged between the secondary driving disk 14 and the secondary transmission disk 13, and a transmission belt is arranged between the main driving turntable 19 and the linkage turntable 17 and the conveying turntable 18 and the linkage turntable 17. The main driving turntable 19 drives the linkage turntable 17 and the conveying turntable 18 to rotate, and the linkage turntable 17 drives the main stirring shaft 16 to rotate. At this time, the concrete slurry is first stirred and mixed by the transmission shaft 26 and falls into the material conveying pipe 23. When the conveying turntable 18 drives the transmission shaft 26 and the spiral blades 24 to rotate, the concrete slurry is pressurized during the rotation process and enters the secondary mixing box 11 in the direction of the spiral blades 24. The main stirring shaft 16 drives the secondary transmission disk 13 to rotate through the secondary driving disk 14, and the secondary transmission disk 13 drives the secondary stirring blades 22 to rotate through the secondary stirring rod 21, so that the concrete slurry The liquid enters the interior of the grouting pipe 6 from the discharge pipe 1 and is finally sprayed out from the grouting head 9. Since foundation grouting is usually carried out inside the drilled grouting hole, if the grouting head 9 is directly inserted into the grouting hole, the grouting head 9 will fall to the bottom of the grouting hole due to gravity. At this time, the bottom of the grouting head 9 is blocked, resulting in a decrease in grouting efficiency and a poor grouting effect. Therefore, an additional fixing device is required to fix the grouting pipe 6. The operator can directly rotate the adjusting ring 4 to drive the adjusting screw rod 3 to rotate to adjust the height of the main support plate 7 on the lower side. When the operator inserts the grouting pipe 6 into the grouting hole, the main support plate 7 will first contact the ground, thereby playing a role in supporting and fixing the grouting head 9. Since the main support plate 7 is rotatably connected to the auxiliary support plate 8, after the grouting head 9 is set, the auxiliary support plate 8 can be flipped to the outside to increase the overall contact area and make the device more stable, so that the overall device does not need additional fixation during the grouting process and can remain stable.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
