Technical Field

[0001] This utility model relates to the field of vertical lowering of retaining piles, specifically to an auxiliary device for vertical lowering of subway retaining piles. Background Technology

[0002] As an important component of the support system for subway tunnel construction, the retaining piles play a crucial role in bearing the soil load on both sides of the station, directly impacting the safety of station construction.

[0003] In subway construction, retaining piles are a key structure for foundation pit support. The accuracy of their vertical lowering directly affects the stability of the support system and the safety of construction. Currently, the lowering process of retaining piles mostly relies on manual calibration or simple mechanical assistance. When the crane lifts the retaining piles vertically, it is necessary to manually pull and drag the retaining piles in all directions to ensure that they are lowered into the foundation pit in a vertical state.

[0004] In traditional construction, retaining piles are prone to tilting due to their own weight, uneven lowering speed, or uneven pulling force by workers. Manual adjustment is difficult to ensure verticality in real time, which may lead to uneven stress on the support structure. In addition, manual pulling and adjusting the vertical lowering of retaining piles is time-consuming and labor-intensive. Therefore, an auxiliary device for the vertical lowering of subway retaining piles is proposed to address the above problems. Utility Model Content

[0013] According to some embodiments of the present utility model, the terminal of the servo motor is externally connected with a battery block.

[0014] Compared with the known prior art, the technical solution provided by the present utility model has the following beneficial effects: First, by passing the retaining pile through the mounting table, the upper cover plate and the mounting support plate, when the pressing rack moves inside the guide notch, the roller at the end of the pressing rack abuts against the outside of the retaining pile, so that the retaining pile is in a vertical state when passing through the central axes of the mounting table, the upper cover plate and the mounting support plate, which is beneficial to the vertical lowering of the retaining pile during construction.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] See attached document Figure 1-6An auxiliary device for vertically lowering subway retaining piles includes an installation platform 1, an installation support plate 14 fixedly connected to the bottom surface of the installation platform 1, a support frame 13 fixedly fixed below the installation support plate 14, an upper cover plate 2 fixedly connected to the top surface of the installation platform 1 by bolts, a guide notch 4 opened on the side of the installation platform 1, a pressing toothed rail 3 movably connected in the guide notch 4, and a roller provided in the end of the pressing toothed rail 3.

[0022] In the above technical solution, by passing the retaining pile through the mounting platform 1, the upper cover plate 2 and the mounting support plate 14, when the extrusion toothed rail 3 moves inside the guide notch 4, the roller at the end of the extrusion toothed rail 3 abuts against the outside of the retaining pile. Therefore, the retaining pile is in a vertical state when passing through the central axis of the mounting platform 1, the upper cover plate 2 and the mounting support plate 14, which is beneficial for the vertical lowering of the retaining pile during construction.

[0023] According to some embodiments of this utility model, a vertical bubble meter 5 is fixedly installed on the outside of the mounting platform 1, and a horizontal bubble meter 6 is fixedly installed on the top surface of the upper cover plate 2. The vertical bubble meter 5 measures whether the upper cover plate 2 is in a horizontal state, and the horizontal bubble meter 6 measures whether the mounting platform 1 is in a vertical state, so as to ensure the stability of the retaining piles vertically downward during construction.

[0024] According to some embodiments of this utility model, an annular groove 8 is provided above the mounting platform 1, and a rotating shaft is fixedly connected inside the annular groove 8. The outside of the rotating shaft is sleeved inside the T-shaped gear 12. The lower teeth of the T-shaped gear 12 mesh with the inner teeth of the annular gear ring 11, and the upper teeth of the T-shaped gear 12 mesh with the upper side teeth of the extrusion tooth rail 3. The rotating shaft inside the T-shaped gear 12 makes it rotate stably in the annular groove 8. Therefore, the T-shaped gear 12 drives the annular gear ring 11 to rotate in the annular groove 8. When the annular gear ring 11 drives the four sets of extrusion tooth rails 3 to move closer to each other in the mounting platform 1, the rollers at the ends of the extrusion tooth rails 3 will press the retaining pile against the vertical central axis of the mounting platform 1 when the retaining pile passes through the mounting platform 1.

[0025] According to some embodiments of this utility model, the outer rotation of the annular gear ring 11 is set inside the annular limiting groove 9, which is opened inside the mounting platform 1. The annular limiting groove 9 and the groove 10 are connected. The groove 10 is opened on the top surface of the mounting platform 1. The outer teeth of the annular gear ring 11 mesh with the teeth of the drive gear 17. The top surface of the drive gear 17 is fixedly connected to the output shaft end of the servo motor 7. The base of the servo motor 7 is fixed above the upper cover plate 2. The terminal of the servo motor 7 is connected to a battery block. When the servo motor 7 is started, the drive gear 17 meshes and drives the annular gear ring 11 to rotate automatically in the annular limiting groove 9. Therefore, the T-shaped gear 12 drives the extrusion gear 3 to move automatically in the mounting platform 1. Thus, it can be adjusted and stabilized according to the radius size of the retaining pile, which plays an auxiliary role in the vertical lowering of the retaining pile.

[0026] According to some embodiments of the present invention, a plug-in groove 15 is provided at the bottom of the mounting platform 1. The outside of the plug-in groove 15 is plugged into the outside of the card plate 16. The bottom surface of the card plate 16 is fixed to the top surface of the mounting bracket 14. By plugging the card plate 16 into the plug-in groove 15, it is convenient to disassemble the mounting platform 1 and the support frame 13.

[0027] In the above technical solution, the vertical bubble meter 5 measures whether the upper cover plate 2 is in a horizontal state, and the horizontal bubble meter 6 measures whether the mounting platform 1 is in a vertical state, ensuring the stability of the retaining pile vertically downward during construction. When the annular gear ring 11 drives the four sets of extrusion gear rails 3 to approach each other in the mounting platform 1, the rollers at the ends of the extrusion gear rails 3 will press the retaining pile against the vertical central axis of the mounting platform 1 when the servo motor 7 is started, the drive gear 17 meshes and drives the annular gear ring 11 to rotate automatically in the annular limiting groove 9. Therefore, the T-shaped gear 12 drives the extrusion gear rails 3 to move automatically in the mounting platform 1, so it can be adjusted and stabilized according to the radius size of the retaining pile, which plays an auxiliary role in the vertical lowering of the retaining pile.

[0028] Working principle: By passing the retaining pile through the mounting platform 1, the upper cover plate 2, and the mounting support plate 14, when the pressing toothed rail 3 moves inside the guide notch 4, the roller at the end of the pressing toothed rail 3 abuts against the outside of the retaining pile. Therefore, the retaining pile is in a vertical state when passing through the central axis of the mounting platform 1, the upper cover plate 2, and the mounting support plate 14, which is beneficial for the vertical lowering of the retaining pile during construction. When the servo motor 7 is started, the drive gear 17 meshes with the drive ring gear ring 11 to automatically rotate in the ring limiting groove 9. Therefore, the T-shaped gear 12 drives the pressing toothed rail 3 to move automatically in the mounting platform 1. Thus, it can be adjusted and stabilized according to the radius size of the retaining pile, which plays an auxiliary role in the vertical lowering of the retaining pile. When the ring gear ring 11 drives the four sets of pressing toothed rails 3 to approach each other in the mounting platform 1, when the retaining pile passes through the mounting platform 1, the roller at the end of the pressing toothed rail 3 abuts the retaining pile against the vertical central axis of the mounting platform 1.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
