Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a longitudinal pouring trolley with variable dimensions adaptable to tunnel slopes. Background Art

[0002] With the increasing economic development and people's living needs in our country, urban expressways and railways can no longer meet the development requirements, and the transportation network connecting various regions and cities urgently needs to be constructed rapidly. Due to the vast territory of our country and extremely complex topographical and geological conditions, transportation routes often pass through large mountainous areas, and tunnels are the most favorable basic construction facilities for crossing mountains. The longitudinal pouring trolley is used for the pouring operation of the secondary lining of the tunnel. At present, during the construction of the secondary lining of the tunnel, the existing technical means for the pouring process of the arch top part mostly adopt upward pouring from the pouring port, similar to the form of a fountain spraying water upward. In the construction of tunnels and underground projects, the traditional longitudinal pouring trolley has the following problems: (1) Due to the error in the initial support contour of the tunnel and the slope in some tunnels, it is easy to form a closed cavity during the upward gushing of concrete, resulting in the inability to discharge air during the pouring of the arch top; (2) The heights of tunnels vary, and the longitudinal pouring trolley cannot adapt to the height changes of the secondary lining of the tunnel, bringing difficulties to the pouring of the arch top of the secondary lining. Summary of the Invention

[0003] The purpose of the utility model is to provide a longitudinal pouring trolley with variable dimensions adaptable to tunnel slopes according to the deficiencies of the above-mentioned prior art. It is composed of a gantry, a longitudinal pouring mechanism, a construction platform, and a traveling mechanism. The angle of the longitudinal pouring trolley can be adjusted by the slope adjustment hydraulic cylinder of the traveling mechanism to adapt to the slope changes in the tunnel. The height of the longitudinal pouring gun of the longitudinal pouring mechanism can be lifted by the vertical hydraulic jack of the longitudinal pouring mechanism to adapt to the pouring of the secondary lining concrete of different tunnel heights, ensuring the safety of tunnel excavation and the whole-life operation.

The tops and the middle parts of the four gantry columns 11 in each group of gantry columns 11 are connected by gantry longitudinal beams 18. There are two groups of gantry longitudinal beams 18 arranged in the vertical direction in the middle of the gantry columns 11. The bottoms of the four gantry columns 11 in each group of gantry columns 11 are connected by a longitudinal base beam 17. The gantry columns 11 and the gantry cross beams 12 are connected by gantry inclined columns 13 to play a strengthening role. The gantry short columns 14 are installed on the gantry cross beams 12 and there are eight gantry short columns 14 arranged along the transverse direction of the gantry cross beams 12, that is, each gantry cross beam 12 is provided with eight gantry short columns 14 along its transverse direction.

The platform 32 is used for construction by construction personnel. The guardrail 31 is installed on the platform 32, and the guardrail 31 plays a protective role.

[0026] As Figures 1 - 2As shown in the figure, the longitudinal pouring mechanism 2 is installed in the middle of the top of the gantry 1. The longitudinal pouring mechanism 2 includes a support 21, a base plate 23, a vertical hydraulic jack 24, a connecting beam 25, a longitudinal pouring gun 26, and a telescopic and rotating motor 27.

There are two groups of vertical hydraulic jacks 24 in the transverse direction. Each group of vertical hydraulic jacks 24 includes three vertical hydraulic jacks 24 arranged at intervals in the longitudinal direction. The two groups of vertical hydraulic jacks 24 are connected by a connecting beam 25. That is, one vertical hydraulic jack 24 in one group of vertical hydraulic jacks 24 is connected to the corresponding vertical hydraulic jack 24 (the vertical hydraulic jack 24 at the same longitudinal position) in the other group of vertical hydraulic jacks 24 by a connecting beam 25. The base plate 23 is connected to the top (fixed end) of the vertical hydraulic jack 24. Two supports 21 are installed on the base plate 23 and arranged along the longitudinal direction of the base plate 23. The telescopic and rotating motor 27 is installed on one of the supports 21. The longitudinal pouring gun 26 sequentially passes through the support hole 22 of one of the supports 21, the telescopic and rotating motor 27, and the support hole 22 of the other support 21.
