DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Refer to the drawings in the description Figures 1-5 The utility model provides a subway tunnel soft soil support device, including base 1, the base 1 top is equipped with two for supporting subway tunnel soft soil structure's support piece, and the base 1 top is installed for adjusting two support piece height's adjusting part,

[0027] As Figure 5As shown, the adjusting component includes a support plate 7 mounted on the top of the base 1. The support plate 7 has a support groove 8 on its top, and a threaded rod 9 connected to it via a bearing is installed inside the support groove 8. A movable plate 10 is threadedly connected to the top of the threaded rod 9. An alarm 5 is mounted on the top of the movable plate 10, and a controller 6 is mounted on the rear side of the top of the support plate 7. Two fixed plates 2 are respectively mounted on both sides of the top of the movable plate 10. The threaded rod 9 drives the movable plate 10, which is limited by the support groove 8, to move up and down, thereby adjusting the height of the support component and improving the practicality of this invention. Since the cross-sections of the movable plate 10 and the support groove 8 are both rectangular, and the outer surface of the movable plate 10 is connected to the support groove 8... The inner walls of the groove 8 are in contact, allowing the support groove 8 to limit the movement of the moving plate 10, thus ensuring the stability of the moving plate 10 during displacement. The base 1 has a through hole 16 on its exterior, and a servo motor 17 is installed inside the through hole 16. The output shaft of the servo motor 17 passes through the base 1 and the support plate 7 in sequence and is fixed to the bottom end of the threaded rod 9. Dustproof nets 18 are provided on both the front and rear sides of the servo motor 17, and the exterior of the dustproof nets 18 is fixed to the inner wall of the through hole 16, so that the servo motor 17 can drive the threaded rod 9 to rotate, thereby improving the rotation efficiency of the threaded rod 9. At the same time, the dustproof nets 18 block dust in the air, preventing dust from adhering to the exterior of the servo motor 17 and affecting heat dissipation.

[0028] like Figures 1-4 As shown, the adjustment component is provided with a detection component for monitoring the support strength of the support component; the detection component includes two fixed plates 2 on the top of the base 1, the top of the two fixed plates 2 is provided with a reflector 3, and the bottom of the reflector 3 is provided with a plurality of distance sensors 4 installed on the top of the fixed plates 2; an alarm 5 and a controller 6 are provided between the two fixed plates 2, and the alarm 5 is located on the top of the controller 6.

[0029] When in use, the staff operates the handle 19 to move the base 1 supported by the self-locking caster 20 to a suitable position in the subway tunnel. Then, the servo motor 17 is started to drive the threaded rod 9 to rotate. The threaded rod 9 drives the moving plate 10, which is limited by the support groove 8, to move upward. In this way, the support plate 15 fixed on the moving plate 10 can be moved to the soft soil structure of the subway tunnel, and the soft soil structure is supported by the support plate 15.

[0030] When the support plate 15 is subjected to heavy pressure and twists the hollow plate 11, the reflector 3 will deform along with the hollow plate 11. At this time, the data information detected by the ranging sensor 4 changes and transmits the ranging information to the controller 6. The controller 6 activates the alarm 5 to issue a warning, inform the staff of the hazard information and timely maintenance, thereby reducing safety accidents and equipment damage.

[0031] To facilitate the support and protection of soft soil structures, such as Figure 1 ,3 As shown in the accompanying drawings, the supporting piece comprises a hollow plate 11 installed at one side of the top end of the moving plate 10, a spring 12 arranged inside the hollow plate 11, a locating seat 13 arranged at the end of the spring 12 away from the moving plate 10, a locating plate 14 installed at the end of the locating seat 13 away from the spring 12, and a supporting plate 15 penetrating through the hollow plate 11 and rotationally connected to the end of the locating plate 14 away from the locating seat 13. The reflecting plate 3 is installed at the bottom of the hollow plate 11. The locating seat 13 and the locating plate 14 are pushed outwards by the tension of the spring 12, and the locating plate 14 further pushes the supporting plate 15 to tightly contact with the soft soil structure, so as to ensure the stability and supporting strength of the supporting plate 15.

[0032] In order to facilitate the movement of the base 1, as shown in the accompanying drawings, a handle 19 is installed at the top of the rear end of the base 1, and a plurality of self-locking universal wheels 20 are installed at the top of the base 1. Figure 1 3 As shown in the accompanying drawings, the supporting piece comprises a hollow plate 11 installed at one side of the top end of the moving plate 10, a spring 12 arranged inside the hollow plate 11, a locating seat 13 arranged at the end of the spring 12 away from the moving plate 10, a locating plate 14 installed at the end of the locating seat 13 away from the spring 12, and a supporting plate 15 penetrating through the hollow plate 11 and rotationally connected to the end of the locating plate 14 away from the locating seat 13. The reflecting plate 3 is installed at the bottom of the hollow plate 11. The locating seat 13 and the locating plate 14 are pushed outwards by the tension of the spring 12, and the locating plate 14 further pushes the supporting plate 15 to tightly contact with the soft soil structure, so as to ensure the stability and supporting strength of the supporting plate 15.

[0033] Finally, the above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
