Description

Technical Field

[0001] This utility model relates to the field of tunnel lining construction technology, specifically to a tunnel lining construction support structure. Background Technology

[0002] Tunnel lining trolleys are specialized equipment essential for secondary processes in tunnel construction. They are used for concrete lining of the tunnel's inner walls. Concrete lining trolleys are indispensable non-standard products in tunnel construction, mainly including simple lining trolleys, fully hydraulic automatic walking lining trolleys, and grid-type lining trolleys. Fully hydraulic lining trolleys can be further divided into side-top arch type, full-circular needle beam type, bottom-form needle beam type, and full-circular through type, etc. Lifting, jacking slipform, and other functions are also commonly used in hydraulic tunnel and bridge construction.

[0003] Tunnel lining support columns are critical temporary structures in tunnel construction. Before the lining concrete is poured, the support columns maintain the stability of the excavation face and prevent deformation or collapse of the surrounding rock by transferring loads to the foundation or existing structure. Existing tunnel lining support structures lack flexibility in lifting and lowering, and the support force mainly relies on the lifting drive components, which not only overworks the lifting components but also reduces the stability of the support.

[0004] Therefore, it is particularly important to design a tunnel lining construction support structure to overcome the above-mentioned technical defects and improve the overall practicality. Utility Model Content

A fixing sleeve 501 is fixedly sleeved on the bottom of the outer side of the support main rod 5. A pulley assembly 502 that slides with the guide rails 201 is installed on the side of the fixing sleeve 501 facing the guide rod 2.

[0023] The support base plate 1 is provided with assembly brackets on both the left and right sides and at both the front and rear ends. The assembly brackets are provided with assembly bolts. The lifting platform plate 4 has grooves on both the left and right sides for the guide rods 2 to pass through, and a groove for the fixing rods 8 to pass through is provided in the center of the lifting platform plate 4.

[0024] In this embodiment, multiple sets of supporting auxiliary rods 6 are installed on the top of the lifting platform plate 4 near the middle. The top of the main supporting rod 5 and the supporting auxiliary rods 6 are jointly installed with a supporting top plate 7. A fixed upright rod 8 is installed in the middle of the top of the supporting bottom plate 1. A forward and reverse motor 801 is installed on the top of the fixed upright rod 8. The output end of the forward and reverse motor 801 passes through the interior of the fixed upright rod 8 and is connected to a rotating screw 802. A screw sleeve 803 is threaded onto the outer side of the rotating screw 802. Lifting brackets 804 are provided on both the left and right sides of the screw sleeve 803.

[0025] The base plate 1 is equipped with a controller, which is connected to the cylinder telescopic rod 3 and the forward and reverse motor 801 by wires and the connection is electrical.

[0026] The working process of this utility model is as follows: Using the tunnel lining construction support structure designed in this scheme, during operation or work, multiple sets of support bottoms 1 of this support structure are installed at different sections of the tunnel lining, ensuring that each section has at least two sets of symmetrical support to avoid unilateral stress and make the support more stable and secure. The forward and reverse motors 801 start and drive the rotating screw 802 to rotate, thereby driving the screw sleeve 803 to move up and down, causing the lifting support rod 804 to lift the top lifting platform plate 4. Simultaneously, multiple sets of cylinder telescopic rods 3 synchronously lift the lifting platform plate 4. Guides are symmetrically arranged on the support bottom plate 1. The guide rail 201 on the outer side of the upright 2 can slide and guide with the pulley assembly 502 of the main support rod 5 on the lifting platform plate 4, making the up and down movement more stable. Finally, the supporting top plate 7 supports the top of the tunnel lining. The support structure is stable. The central lifting power is formed by the fixed upright 8, the forward and reverse motor 801, and the rotating screw 802. Four sets of cylinder telescopic rods 3 are added to form the side lifting power. The whole can share the load. In addition, the main support rod 5 and the secondary support rod 6 are evenly distributed between the lifting platform plate 4 and the supporting top plate 7, so as to avoid unilateral force, make the support more stable and firm, and reduce the interference to the surrounding environment.
