Embodiment 1

[0040] refer to figure 1 , the device includes a transportation track 1, a transportation pump truck 2, a grouting pipeline 3 and a transfer elbow 4. Wherein, the transportation track 1 and the transportation pump truck 2 are all arranged on the trolley frame 100, specifically, the trolley frame 100 is arranged along the traveling direction of the trolley, and is used as the main supporting structure of the trolley to support the two sides of the trolley. Side and top molds.

[0041] The transport track 1 is arranged in the top space of the trolley frame 100, and is also arranged along the traveling direction of the trolley. The transport track 1 includes two monorails arranged in parallel, which can be welded and fixed on the trolley frame 100, or can be passed through Bolts are fixed on the trolley stand 100. In this embodiment, the transport track 1 uses I-beam as the material, and brake structures are arranged at both ends.

[0042] refer to figure 1 and 2, the transpo...

Embodiment 2

[0049] refer to Figure 4 , as another embodiment of the present application, the grouting device adds a pressurized assembly 5 on the basis of Example 1, and the pressurized assembly 5 is arranged between the transfer elbow 4 and the upper pipeline 32, and the pressurized The component 5 exerts pressure on the mortar entering the upper 32 pipeline to speed up the flow velocity of the mortar and improve the pouring efficiency of the lining structure.

[0050] The pressurizing assembly 5 includes a two-part structure of a storage box 51 and a pressurizing part, wherein the storage box 51 is arranged on both sides of the transportation track 1 along the direction of the transportation track 1, and is located between the transportation pump truck 2 and the upper pipeline 32 room, the inside of the material storage box 51 is divided into several single rooms, and each single room is connected with at least one group of grouting pipelines 3, and each single room is connected with a...

Abstract

The invention relates to the technical field of lining trolleys, in particular to a grouting device with a mold for an automatic lining trolley. Comprising a transportation track arranged on the top of a trolley rack, a transportation pump truck arranged on the transportation track in a sliding mode, a plurality of sets of grouting pipelines arranged downwards along a trolley formwork and a transfer bent pipe connected between the transportation pump truck and the grouting pipelines, and the grouting pipelines are arranged along the two sides of the transportation track; the lower ends of the grouting pipelines are provided with chutes penetrating through the trolley formwork to the outer side, the transfer bent pipes comprise a plurality of bent pipes connected end to end, the adjacent bent pipes are rotationally connected, and the transfer bent pipes are rotationally communicated with the grouting pipelines respectively. The grouting device of the lining trolley is simple in structure and convenient to use, and the grouting difficulty of a lining structure is reduced.

Description

technical field [0001] The present application relates to the technical field of lining trolleys, in particular to a belt-mold grouting device for automatic lining trolleys. Background technique [0002] The lining trolley is a special equipment that must be used in the secondary lining during the tunnel construction process, and is used for the concrete lining construction of the inner wall of the tunnel. Concrete lining trolley is an indispensable non-standard product for secondary lining in the tunnel construction process, mainly including simple lining trolley, fully hydraulic automatic walking lining trolley and grid lining trolley. Fully hydraulic lining trolley can be divided into side-top arch type, full-circle needle beam type, bottom mold needle-beam type, full-circle walking type, etc. [0003] In the related art, the lining trolley generally adopts the chute-type pouring method when pouring concrete. However, the inventors found that this method is heavy in str...
