Description

Technical Field

[0001] This utility model relates to the field of mixing pile technology, specifically a multi-head small-diameter mixing pile with adjustable pile spacing. Background Technology

[0002] The prior art patent document CN221372161U discloses a multi-head small-diameter mixing pile. This device, through its column design, effectively prevents collapse during mixing due to insufficient gaps between adjacent columns, thus improving worker efficiency. The cavity design effectively prevents soil and rocks from falling into the poured cement column during drilling, thereby increasing the column's utilization efficiency. The column door design allows for quick removal of soil from the cavity, preventing excessive soil buildup and blockage, further improving worker efficiency.

[0003] Although the existing technical solutions mentioned above can avoid the problem of collapse due to excessively small gaps between adjacent columns through column design, they still have the following drawbacks: the existing technology requires the output of soil, which involves many mixing steps and results in low efficiency in pouring the pile foundation. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide a multi-head small-diameter mixing pile with adjustable pile spacing, which solves the problem of multiple mixing steps and low efficiency of pile foundation pouring.

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0006] A multi-head small-diameter mixing pile with adjustable pile spacing, characterized in that: it includes a mixing mechanism, the mixing mechanism includes a grouting rod, the lower end of the grouting rod is connected and fixed with a grouting head, the lower part of the grouting rod is connected and fixed with multiple mixing blades, the lower part of the grouting rod is connected and fixed with multiple connecting rods, and the ends of the multiple connecting rods are connected and fixed with partition cylinders;

[0007] The grouting rod drives the mixing blade to rotate rapidly, breaking up the ground and mixing it. At the same time, the grouting head injects and mixes the grout. Then, under the isolation of the partition, the soil and cement slurry are mixed. Due to the isolation of the partition, adjacent mixing piles will not interfere with each other, thus forming a stable pile foundation.

[0008] The adjustable-spacing multi-head small-diameter mixing pile is characterized in that: a rotating motor is fixedly connected to the upper end of the grouting rod, and an installation frame is provided outside the rotating motor, and the installation frame is fixedly installed to the vehicle frame.

[0009] The adjustable-spacing multi-head small-diameter mixing pile is characterized in that: an adjustment mechanism is fixedly installed at the ends of the two rotating motors located at the outer end; the adjustment mechanism includes two sliding grooves opened on the bottom surface of the mounting frame; a slider is slidably connected inside the sliding grooves; a rack is fixedly connected to the lower end of the slider; gears are meshed at the inner ends of the two racks; a hydraulic push rod is fixedly connected to one of the racks; the other end of the hydraulic push rod is fixedly connected to the mounting frame; the gear is rotatably connected to the mounting frame; and the grouting rod is rotatably connected to the slider.

[0010] When the pile spacing needs to be adjusted, a hydraulic push rod drives one rack to move, which in turn drives another rack through the intermediate drive of the gear. The two sliders are then moved synchronously, which in turn moves the motor and mixing mechanism on the sliders to adjust the pile spacing synchronously and stably, ensuring the accuracy of the pile spacing.

[0011] The adjustable-spacing multi-head small-diameter mixing pile is characterized in that: the other ends of the two rotating motors located at the outer end are connected and fixed with two limiting slide plates, and the limiting slide plates are slidably connected to the mounting frame.

[0012] The adjustable-spacing multi-head small-diameter mixing pile is characterized in that: the upper ends of the two rotating motors located at the outer end are connected and fixed with electric push rods, and the inner wall of the mounting frame is provided with multiple slots, and the electric push rods are inserted into the slots for cooperation;

[0013] The electric push rod at the top of the motor, in conjunction with the slot, further limits and fixes the motor after it moves, preventing it from shaking during subsequent use and ensuring the stability of the mixing pile.

[0014] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a multi-head small-diameter mixing pile with adjustable pile spacing. By adopting the above technical solution and the design of the mixing mechanism, the grouting rod can drive the mixing plate to rotate quickly, thus breaking the ground and mixing. At the same time, the grouting head performs grouting and mixing. Then, under the isolation of the partition, the soil and cement slurry are mixed. Due to the isolation of the partition, adjacent mixing piles will not interfere with each other. The resulting pile foundation is more stable and has a higher quality qualification rate. Finally, there are fewer existing steps, and the efficiency of pouring the pile foundation is higher.

[0015] This application, through the design of the adjustment mechanism, allows for the movement of a rack via a hydraulic push rod when the pile spacing needs adjustment. This movement, driven by the intermediate gear, moves the other rack, and the two sliders move synchronously. This, in turn, moves the motor and mixing mechanism on the sliders, thus synchronously and stably adjusting the pile spacing and ensuring its accuracy. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0023] Reference Figure 1 and Figure 2 This application discloses a multi-head small-diameter mixing pile. The mixing mechanism 1 includes a grouting rod 2, a grouting head 3 fixedly connected to the lower end of the grouting rod 2, multiple mixing blades 4 fixedly connected to the lower part of the grouting rod 2, multiple connecting rods 5 fixedly connected to the lower part of the grouting rod 2, and a partition cylinder 6 fixedly connected to the end of the multiple connecting rods 5.

[0024] The design of the mixing mechanism 1 allows the grouting rod 2 to drive the mixing plate 4 to rotate rapidly, thus breaking up the ground and mixing it. At the same time, the grouting head 3 injects grout and mixes it. Then, under the isolation of the partition cylinder 6, the soil and cement slurry are mixed. Due to the isolation of the partition cylinder 6, adjacent mixing piles will not interfere with each other. The resulting pile foundation is more stable and has a higher quality qualification rate. Finally, there are fewer steps and the efficiency of pouring the pile foundation is higher.

[0025] Reference Figure 3 and Figure 4The upper end of the grouting rod 2 is connected to and fixed with a rotating motor 7. The rotating motor 7 is provided with a mounting frame 8 outside, and the mounting frame 8 is fixed to the vehicle frame.

[0026] Preferably, the ends of the two rotating motors 7 located at the outer end are fixed with an adjustment mechanism 9. The adjustment mechanism 9 includes two slide grooves 10 opened on the bottom surface of the mounting frame 8. A slider 11 is slidably connected inside the slide groove 10. A rack 12 is fixedly connected to the lower end of the slider 11. Gears 13 are meshed and connected to the inner ends of the two racks 12. A hydraulic push rod 14 is fixedly connected to one of the racks 12. The other end of the hydraulic push rod 14 is fixedly connected to the mounting frame 8. The gear 13 is rotatably connected to the mounting frame 8. The grouting rod 2 is rotatably connected to the slider 11.

[0027] The design of the adjustment mechanism 9 allows for the movement of one rack 12 via the hydraulic push rod 14 when the pile spacing needs adjustment. This movement is then driven by the intermediate drive of the gear 13, which in turn drives the other rack 12. Consequently, the two sliders 11 are moved synchronously, which in turn moves the motor 7 and the mixing mechanism 1 on the sliders 11. This allows for the synchronous and stable adjustment of the pile spacing, ensuring its accuracy.

[0028] Reference Figure 3 The other ends of the two rotating motors 7 located at the outer end are connected and fixed with two limiting slide plates 15, which are slidably connected to the mounting frame 8.

[0029] The sliding connection between the limiting slide plate 15 and the mounting frame 8 allows for stable rotation of the upper end of the motor 7.

[0030] Two rotating motors 7 located at the outer end are connected and fixed with electric push rods 16. Multiple slots 17 are provided on the inner wall of the mounting frame 8, and the electric push rods 16 are inserted into the slots 17.

[0031] The electric push rod 16 at the upper end of the rotating motor 7, in conjunction with the slot 17, can further limit and fix the rotating motor 7 after it moves, preventing it from shaking during subsequent use and ensuring the stability of the mixing pile.

[0032] The implementation principle of the adjustable-spacing multi-head small-diameter mixing pile in this application embodiment is as follows: During use, the grouting rod 2 at the end of the rotating motor 7 drives the mixing plate 4 to rotate rapidly, thus breaking up the ground and mixing it. At the same time, the grouting head 3 performs grouting and mixing. Then, under the isolation of the partition cylinder 6, the soil and cement slurry are mixed and stirred. Due to the isolation of the partition cylinder 6, adjacent mixing piles will not interfere with each other, and the resulting pile foundation is relatively stable. When the pile foundation spacing needs to be adjusted, the hydraulic push rod 14 drives one rack 12 to move. Thus, through the intermediate drive of the gear 13, the other rack 12 can be driven to move. In this way, the two sliders 11 will be driven synchronously, which can drive the motor 7 and the mixing mechanism 1 on the slider 11 to move and adjust. In this way, the pile foundation spacing can be adjusted synchronously and stably to ensure the accuracy of the pile foundation spacing.

[0033] The above are merely embodiments provided in this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
