Description

Technical Field

[0001] The utility model relates to the technical field of secondary lining trolleys, in particular to a large longitudinal slope trolley pouring system for a tunnel without gantry secondary lining trolleys. Background Technique

[0002] The concrete lining trolley is a special equipment that must be used in the secondary lining during the tunnel construction process for the concrete lining construction of the tunnel inner wall. The concrete lining trolley is an indispensable non-standard product in the secondary lining during the tunnel construction process, mainly including simple lining trolleys, fully hydraulic automatic walking lining trolleys and grid-type lining trolleys. The fully hydraulic lining trolley can be further divided into side-top-arch type, full-circle needle beam type, bottom form needle beam type, full-circle passing type, etc. In the construction of hydraulic tunnels and bridges, lifting slip forms, jacking slip forms and turnover forms are also commonly used.

[0003] The pouring system in traditional tunnel construction often fails to work effectively in tunnels with large longitudinal slopes because the large slope may cause uneven concrete flow or difficult control, making it inconvenient to use. Therefore, we propose a large longitudinal slope trolley pouring system for a tunnel without gantry secondary lining trolleys to solve the above-mentioned technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the pouring system in traditional tunnel construction often fails to work effectively in tunnels with large longitudinal slopes because the large slope may cause uneven concrete flow or difficult control, and to propose a large longitudinal slope trolley pouring system for a tunnel without gantry secondary lining trolleys.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A large longitudinal slope trolley pouring system for a tunnel without gantry secondary lining trolleys, including a trolley body, a trolley pouring main machine is slidably connected to the top of the trolley body, a hopper moving trolley is arranged on the top of the trolley pouring main machine, a three-way distribution pipe is fixedly communicated with one side of the hopper moving trolley, a plurality of pouring holes are respectively arranged on both sides of the trolley body, a plurality of waste collection grooves are arranged on the trolley body, a first-layer feeding pipe, a second-layer feeding pipe, a third-layer feeding pipe, a fourth-layer feeding pipe and a fifth-layer feeding pipe are respectively arranged on both sides of the trolley body, the first-layer feeding pipe, the second-layer feeding pipe, the third-layer feeding pipe, the fourth-layer feeding pipe and the fifth-layer feeding pipe are respectively used in cooperation with the plurality of pouring holes, and a feeding assembly for feeding the trolley pouring main machine is arranged on the inner wall of one side of the trolley body.

[0007] In a possible design, the feeding assembly includes a horizontal dragging and fixing pipe fixedly connected to one side of the trolley casting main machine. One end of the horizontal dragging and fixing pipe is provided with a first elbow. One end of the first elbow is fixedly connected to a first horizontal dragging pipe. One end of the first horizontal dragging pipe is fixedly connected to a second horizontal dragging pipe. One end of the second horizontal dragging pipe is provided with a high-pressure pump pipe clamp. One end of the high-pressure pump pipe clamp is fixedly connected to a vertical fixing straight pipe. One end of the vertical fixing straight pipe is fixedly connected to a second elbow. One end of the second elbow is fixedly connected to the main machine feeding pipe.

[0008] In a possible design, a feeding pipe hanger is provided on the inner wall of one side of the trolley body. The feeding pipe hanger is used to support the main machine feeding pipe. A feeder is provided on one side of the trolley body. The feeder is used to supply materials to the main machine feeding pipe.

[0009] In a possible design, a plurality of side form distribution pipes are arranged inside the trolley body. A plurality of first feeding chutes and second feeding chutes are arranged on both sides of the trolley body. The side form distribution pipes are used in cooperation with the first feeding chutes and the second feeding chutes. The first feeding chutes are used in cooperation with the first-layer feeding pipe, the second-layer feeding pipe, the third-layer feeding pipe, and the fourth-layer feeding pipe. The second feeding chutes are used in cooperation with the fifth-layer feeding pipe.

[0010] In a possible design, a plurality of trolley cleaning heads are arranged on the trolley body.

[0011] In a possible design, a cable reel is arranged at one end of the trolley body.

[0012] Beneficial effects:

[0013] 1. The tunnel has a relatively large longitudinal slope, such as 9% or other slopes as shown in the figure.

[0014] 2. The tunnel secondary lining trolley adopts a design without a gantry system (this name is inaccurate. Theoretically, it has fewer gantries). There is no traditional supporting screw rod between the gantry and the formwork. A large hinge rod is provided at the position of the upper longitudinal beam and supports at a position slightly below the middle of the formwork.

[0015] 3. The characteristics of the trolley without a gantry are as follows: The formwork system has sufficient strength. It is vertically and obliquely reinforced and locked at the position where the formwork supports the ground, and the large hinge rod at the side form position is locked. When pouring concrete, the formwork will not deform or shift.

[0016] 4. In order to prevent the gantry from tilting and deforming on a large slope, a lower longitudinal beam is provided under the column, and a gantry column brace is set. The advantage of this is that the support point is outward, preventing the center of gravity of the trolley from being outside the fulcrum and preventing the trolley from tipping over when walking.

[0017] 5. To prevent the trolley from slipping when walking, the secondary lining trolley adopts an oil cylinder pushing and stepping walking method.

[0018] 6. A distributing trolley is provided on the cross beam of the trolley bracket. There is a towing pipe behind the distributing trolley to prevent insufficient power for the trolley to climb the slope. A gear-rack device is provided under the trolley, which is driven by a high-torque hydraulic motor and equipped with a hydraulic braking system. A concrete inlet window pipeline is provided in front of the trolley.

[0019] a. Only one hopper is provided above the trolley. It can move longitudinally with the pouring trolley.

[0020] b. Telescopic chutes are provided at the discharge openings on both sides of the hopper.

[0021] c. When the hopper needs to move longitudinally with the trolley, the chutes at both ends of the discharge hopper need to be retracted.

[0022] d. Travel tracks are provided on both sides of the hopper.

[0023] 7. Compared with the traditional rotary pouring system, the trolley pouring system reduces the number of pipelines above the trolley and the labor intensity of pipeline cleaning.

[0024] The characteristics of this trolley are a large longitudinal slope and a gantry-free structure, and a longitudinal pouring system for the trolley is provided. Brief Description of the Drawings
