Description

Technical Field

[0001] This utility model relates to the field of tunnel construction, and in particular to an arch-top trolley. Background Technology

[0002] For example, Chinese Utility Model Patent Publication No. CN 205918432 U discloses a biomimetic hydraulic stepping arch inner formwork lining trolley for open-cut tunnels, including a gantry, a trolley top, a combined crossbeam, and a rotating column whose upper end is connected to the upper node on the combined crossbeam by a connecting pin, and whose lower end is connected to the traveling beam at the lower node by a connecting pin; a bending cylinder passes through the combined crossbeam to connect the rotating column and the anti-cantilever crossbeam. This design is not conducive to stable support during pouring, requires the entire trolley to move back and forth during movement, and consumes a large amount of power. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an arch trolley that can stably support the formwork during concrete pouring, and the entire trolley can be moved and lifted separately in the upper and lower parts, which helps to reduce power consumption.

[0004] To solve the above problems, a dome-shaped trolley was adopted, which includes:

[0005] The first track is laid parallel at intervals;

[0006] The first electric wheel frame is arranged at intervals on the first track;

[0007] The first bottom longitudinal beam is fixed at its front and rear ends to the first electric wheel frame;

[0008] The support frame has its uprights fixed to the first bottom longitudinal beam;

[0009] Boot supports are located on both sides of the boot support frame;

[0010] The first lifting cylinder is located below the first bottom longitudinal beam, with its telescopic end facing the first track;

[0011] The top longitudinal beams are fixed parallel to the support frame at intervals;

[0012] The second track is laid on the top longitudinal beam;

[0013] The second electric wheel frame is set at intervals on the second track;

[0014] The second bottom longitudinal beam is fixed at its front and rear ends to the second electric wheel frame;

[0015] The arched portal frame has its columns fixed to the second bottom longitudinal beam;

[0016] The second lifting cylinder is fixedly connected at intervals to the bottom of the second longitudinal beam, and its telescopic end faces the second track.

[0017] The electric push rod is fixed at its bottom to the crossbeam of the arch frame;

[0018] The arch formwork is connected to the telescopic end of the upper part of the electric push rod;

[0019] With this structure, the support shoe gantry and the arch gantry can be separated, and the support shoe of the support shoe gantry can abut against the inner wall around the tunnel to keep the trolley stable.

[0020] As a further improvement of this utility model, the arch template is provided with working windows and vibration holes at intervals.

[0021] With this structure, concrete can be poured through the working window and compacted by an attached vibrator installed through the vibration hole.

[0022] As a further improvement of this utility model, a clamping plate is added to the arch template, the clamping plate covers the notch of the arch template, and is then fixed by bolts and positioning pins.

[0023] With this structure, the plywood can be assembled with the arch formwork and other formwork to form a whole.

[0024] As a further improvement of this utility model, the arch template includes an inner mold and an outer mold, which are fixed by anchor rods.

[0025] With this structure, once the inner and outer molds are fixed, it is easy to support the formwork and pour concrete.

[0026] As a further improvement of this utility model, a soft overlap mold is provided at the rear end of the arch template. The soft overlap mold includes a first end plate and a second end plate spaced apart; and a rib plate located between the first end plate and the second end plate; a pad plate is connected to the first end plate, the second end plate and the rib plate, and a rubber strip is laid on the pad plate. A back bolt is provided on the rubber strip and passes through the pad plate and is tightened.

[0027] With this structure, the rubber strip is supported and can press tightly at the overlap when it overlaps with the previous section of secondary lining concrete to prevent grout leakage at the overlap. The rubber strip can also prevent the concrete from being crushed during the overlap.

[0028] As a further improvement of this utility model, a limiting plate is provided on the side of the rubber strip, and the limiting plate is fixedly connected to the side of the second end plate and the pad.

[0029] With this structure, when the rubber strip is compressed, the pressure at the contact edge with the concrete is increased due to the constraint of the limiting strip, thus further preventing grout leakage.

[0030] As a further improvement of this utility model, the surface of the rubber strip is provided with an inclined V-shaped notch.

[0031] With this structure, the inclined V-shaped notch can be used as an overlap position. At this time, the edge of the upper section of secondary lining concrete can extend into the V-shaped notch, and the entire contact edge forms a V-shaped zigzag line instead of a horizontal line, which better prevents grout leakage.

[0032] This invention provides stable formwork support during concrete pouring, and the entire trolley can be moved vertically, which helps reduce power consumption. Attached Figure Description
