Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides a new technical solution: an installation mechanism for precast special-shaped pipe piles, including a mounting base plate 1, and four vertical plates 2 are fixedly installed on the upper surface of the mounting base plate 1. The opposite surfaces of the four vertical plates 2 are all slidably sleeved with sliding grooves 3;

[0029] Among them, a fixing mechanism is provided on the mounting base plate 1. The fixing mechanism includes four first threaded rods 4, four first knobs 5, four moving blocks 6, four first support rods 7, four second support rods 8, four moving plates 9, four insertion rods 10, four second knobs 11, four second threaded rods 12, four sliding blocks 13, sixteen fixing blocks 14, sixteen fixing rods 15, sixteen springs 16 and sixteen spring grooves 17.

[0030] Furthermore, the lower ends of the four first threaded rods 4 are respectively rotatably connected to the inner surfaces of the four sliding grooves 3, the upper ends of the four first threaded rods 4 respectively penetrate through the upper surfaces of the four vertical plates 2, and the four moving blocks 6 are respectively threadedly sleeved on the outer surfaces of the four first threaded rods 4;

[0031] Among them, the four first knobs 5 are respectively fixedly installed on the upper ends of the four first threaded rods 4.

[0032] Furthermore, the four first support rods 7 are respectively rotatably connected to the opposite surfaces of the four moving blocks 6, the four second support rods 8 are respectively rotatably connected to the opposite ends of the four first support rods 7, and the lower ends of the four second support rods 8 are respectively rotatably connected to the opposite surfaces of the four vertical plates 2;

[0033] Among them, four moving plates 9 are rotatably connected to the opposite ends of four second support rods 8.

[0034] Furthermore, four insertion rods 10 are fixedly installed on the lower surface of the installation base plate 1, and sixteen spring grooves 17 are respectively opened in the inner walls of the four insertion rods 10.

[0035] Furthermore, the lower ends of the four second threaded rods 12 are respectively rotatably connected to the inner walls of the four insertion rods 10, and the upper ends of the four second threaded rods 12 all penetrate through the upper surface of the installation base plate 1;

[0036] Among them, four sliding blocks 13 are respectively threadedly sleeved on the outer surfaces of the four second threaded rods 12.

[0037] Furthermore, sixteen springs 16 are respectively fixedly installed in the inner walls of the sixteen spring grooves 17, sixteen fixing blocks 14 are respectively fixedly installed at the opposite ends of the sixteen springs 16, and the upper surfaces of the sixteen fixing blocks 14 are all arranged in an inclined plane.

[0038] Among them, sixteen fixing rods 15 are respectively fixedly installed on the opposite surfaces of the sixteen fixing blocks 14, and the sixteen fixing rods 15 respectively slide through the outer surfaces of the insertion rods 10;

[0039] When the installation mechanism of the prefabricated special-shaped pipe pile is in use, place the square pipe pile on the opposite surfaces of the four moving plates 9. At this time, by rotating the first knob 5, the first knob 5 drives the first threaded rod 4 fixedly installed on the lower surface to rotate. At this time, the first threaded rod 4 drives the moving block 6 threadedly sleeved on the outer surface to continuously move downward through the thread provided on the outer surface of the first threaded rod 4. At the same time, the moving block 6 drives the first support rod 7 rotatably connected to the front surface to gradually move downward. While the first support rod 7 moves downward, it gradually becomes horizontal. At the same time, the first support rod 7 gradually moves forward with respect to the second support rod 8 rotatably connected to the lower end. At the same time, the second support rod 8 rotates on the front surface of the vertical plate 2. At this time, the second support rod 8 exerts a forward thrust on the moving plate 9 rotatably connected to the upper end, causing the moving plate 9 to move forward. At this time, the four moving plates 9 clamp and fix the square pipe pile to complete the installation. By inserting the insertion rods fixedly installed on the lower surface of the installation base plate 1 into the soil, at this time, by rotating the second knob 11, the second knob 11 drives the second threaded rod 12 fixedly installed on the lower surface to rotate. At this time, the sliding block 13 threadedly sleeved on the outer surface of the second threaded rod 12 continuously moves downward through the thread provided on the outer surface of the second threaded rod 12. At this time, the sliding block 13 hits the inclined surface of the fixing block 14. At this time, the fixing block 14 exerts a pressure on the fixing rod 15 fixedly installed on the opposite surface, causing it to move toward the opposite surface, making it slide through the outer surface of the insertion rod 10. At the same time, the fixing block 14 exerts a pressure on the spring 16, causing it to contract;

[0040] The installation mechanism of the precast special-shaped pipe pile can drive four moving plates to move towards the opposite surfaces through the first threaded rod, clamp and fix the square pipe pile through the four moving plates, and a stable triangular force-bearing structure is formed between the second support rod, the moving plate and the installation bottom plate, which can enable the moving plate to stably support the square pipe pile to form installation. Moreover, for the installation mechanism of the precast special-shaped pipe pile, the contact area with the soil is increased by sliding four fixing rods through the outer surface of the insertion rod, and the installation bottom plate can be fixed more stably.

[0041] Working principle: When the installation mechanism of the precast special-shaped pipe pile is in use, place the square pipe pile on the opposite surfaces of the four moving plates 9. At this time, rotate the first knob 5, and the first knob 5 drives the first threaded rod 4 fixedly installed on the lower surface to rotate. At this time, the moving block 6 sleeved on the outer surface of the first threaded rod 4 continuously moves downward through the thread provided on the outer surface of the first threaded rod 4. At the same time, the moving block 6 drives the first support rod 7 rotatably connected to the front surface to gradually move downward. While the first support rod 7 moves downward, it gradually becomes horizontal. At the same time, the first support rod 7 gradually moves forward the second support rod 8 rotatably connected to the lower end. At the same time, the second support rod 8 rotates on the front surface of the vertical plate 2. At this time, the second support rod 8 exerts a forward thrust on the moving plate 9 rotatably connected to the upper end, causing the moving plate 9 to move forward. At this time, the four moving plates 9 clamp and fix the square pipe pile to complete the installation. By inserting the insertion rod fixedly installed on the lower surface of the installation bottom plate 1 into the soil, at this time, rotate the second knob 11, and the second knob 11 drives the second threaded rod 12 fixedly installed on the lower surface to rotate. At this time, the sliding block 13 sleeved on the outer surface of the second threaded rod 12 continuously moves downward through the thread provided on the outer surface of the second threaded rod 12. At this time, the sliding block 13 hits the inclined surface of the fixed block 14. At this time, the fixed block 14 exerts a pressure on the fixing rod 15 fixedly installed on the opposite surface, causing it to move towards the opposite surface, so that it slides through the outer surface of the insertion rod 10. At the same time, the fixed block 14 exerts a pressure on the spring 16, causing it to contract.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
