[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 5The telescopic support pile for building foundation pit support shown includes a base plate 1. An auxiliary mechanism 2 is provided on the upper surface of the base plate 1. The auxiliary mechanism 2 includes a fixed plate 21. A handrail 22 is rotatably connected to the upper surface of the fixed plate 21. The handrail 22 facilitates operation by the operator, and its rotating design allows for more flexible operating angles. A chain tooth 23 is fixedly connected to the outer arc surface of the handrail 22, and the chain tooth 23 meshes with a chain 24. A gear is rotatably connected to the upper surface of the fixed plate 21. 25. Gear 25 is connected to chain tooth 26 via a drive shaft. Chain tooth 26 meshes with chain 24. Gear 25 is also rotatably connected to the upper surface of the fixing plate 21. Gear 25 is connected to chain tooth 26 via a drive shaft, so that the rotation of gear 25 can be transmitted to chain tooth 26. Chain tooth 26 also meshes with chain 24, so that the movement of chain 24 can drive chain tooth 26 and the connected gear 25 to rotate. The fixing plate 21 penetrates the base plate 1 and is slidably connected to the base plate 1. A second gear 27 is rotatably connected to the upper surface, meshing with a first gear 25. The second gear 27 is fixedly connected to a lead screw 28, which passes through and is threadedly connected to the insertion rod 29. The upper surface of the substrate 1 has an insertion rod 29 that is slidably connected to it. Two sets of gears 25, 27, 26, and 29 are symmetrically arranged about the center line of the substrate 1. The center line of plate 1 is symmetrically arranged with the axis of symmetry. This symmetrical arrangement ensures the stability of the structure and the balance of operation. A limiting rod 210 is fixedly connected to the upper surface of the base plate 1. The limiting rod 210 passes through the insertion rod 29 and is slidably connected to the insertion rod 29. The limiting rod 210 restricts the movement trajectory of the insertion rod 29 and prevents the insertion rod 29 from deviating during movement. A pin 211 passes through the front surface of the base plate 1 and is slidably connected to the pin 211. The pin 211 passes through the fixing plate 21 and is slidably connected to the fixing plate 21.

[0026] Specifically: When it is necessary to lay the substrate 1 in the soil, a worker stands on the substrate 1. With the help of the worker's weight, the substrate 1 will sink into the soil. At the same time, after the worker holds the handrail 22, he rotates the handrail 22. The handrail 22 drives the chain tooth 23 to rotate. In conjunction with the chain 24, it drives the chain tooth 26 to rotate. Then, the transmission shaft drives the gear 25 to rotate. Since the gear 25 meshes with the gear 27, after the gear 25 rotates, the gear 27 drives the lead screw 28 to rotate. After the lead screw 28 rotates, the insertion rod 29 will move downward, making it easier for the worker to bury the substrate 1 in the soil.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0029] In a preferred embodiment, a protective plate mechanism 3 is provided on the upper surface of the substrate 1. The protective plate mechanism 3 includes a vertical cone rod 31. This sliding connection design provides a basis for the flexible adjustment of the entire protective plate mechanism 3, allowing the vertical cone rod 31 to be displaced vertically on the substrate 1 according to the needs of the actual use scenario, thereby adapting to different working conditions. The vertical cone rod 31 penetrates the substrate 1 and is slidably connected to the substrate 1. A support plate body 32 is rotatably connected to the upper surface of the vertical cone rod 31. In practical applications, the support plate body 32 can flexibly change its tilt angle according to the specific needs of protection or support to achieve the best working state. A reinforcing rod 33 is fixedly connected to the lower surface of the support plate body 32. The reinforcing rod 33 can effectively disperse and transmit stress, prevent loosening or damage at the connection points, and ensure the structural reliability of the entire protective plate mechanism 3. The reinforcing rod 33 penetrates the vertical cone rod 31 and is rotatably connected to the vertical cone rod 31.

[0030] In a preferred embodiment, a triangular locking rod 34 is slidably connected to the right surface of the vertical cone rod 31. The triangular locking rod 34 is fixedly connected to one end of the spring 35, and the vertical cone rod 31 is fixedly connected to the other end of the spring 35. When the triangular locking rod 34 is subjected to an external force, the spring 35 will deform accordingly, and use its own elastic force to buffer and adjust the position of the triangular locking rod 34 in order to maintain the balance and stability of the entire mechanism.

[0031] In a preferred embodiment, the lower surface of the support plate body 32 is provided with a circular array of slots 36. These slots 36 are slidably connected to triangular locking rods 34. This circular array of slots 36, in conjunction with the triangular locking rods 34, allows the triangular locking rods 34 to slide and position themselves in the slots 36 at different positions when the support plate body 32 rotates about the vertical cone rod 31. This method allows for precise control of the angular position of the support plate body 32 after rotation, achieving accurate positioning and fixation of the support plate body 32 at multiple angles, meeting diverse protection and support needs. For example, when providing protection and support for objects of different shapes or sizes, the support plate body 32 can be adjusted to the most suitable angle according to the actual situation and fixed by the cooperation of the triangular locking rods 34 and the slots 36, thereby ensuring that the support plate mechanism 3 performs at its best.

[0032] The working process of this utility model is as follows: First, when the base plate 1 needs to be laid in the soil, the support plate body 32 is rotated 90 degrees to ensure that the support plate body 32 will not affect the worker's operation. When the support plate body 32 is rotated, the support plate body 32 will drive the slot 36 to rotate. The slot 36 will squeeze the inclined surface of the triangular locking rod 34, causing the triangular locking rod 34 to disengage from the slot 36. At the same time, the spring 35 is compressed. After the support plate body 32 stops rotating, the triangular locking rod 34 is springed back into the slot by the spring 35. Within the groove 36, the support plate body 32 is limited. After the worker holds the handrail 22, he rotates the handrail 22. The handrail 22 drives the chain tooth 23 to rotate. In conjunction with the chain 24, it drives the chain tooth 26 to rotate. Then, the transmission shaft drives the gear 25 to rotate. Since the gear 25 meshes with the gear 27, after the gear 25 rotates, the gear 27 drives the lead screw 28 to rotate. After the lead screw 28 rotates, the insertion rod 29 moves downward. The above is the working principle of the telescopic support pile for the foundation pit support of this building.
