Problems solved by technology

The working mode of this kind of trolley is alternate movement, the structure is relatively complex, and the manufacturing cost is high; during the concrete curing period, the vibration of slag transport vehicles and pedestrians passing through the fasting trolley frame will be transmitted to the inverted arch formwork And affect the pouring quality of the incompletely solidified concrete

Embodiment 1

[0023] see Figure 1-3 , the composition of the tunnel inverted arch formwork trolley of the present invention comprises an anti-floating platform 2, a front traveling wheel 8, a rear traveling wheel 10, a lifting type front support seat 7, a rear support seat 9, and an empty stomach with a column 4 and a driving chassis 11. Type trolley frame 1 and the inverted arch formwork 3 arranged under the undercarriage 11, the front support base 7, the rear support base 9, the front travel wheels 8, and the rear travel wheels 10 are all installed at the bottom of the trolley frame 1. The anti-floating platform 2 is installed on the top of the trolley frame 1. The front traveling wheel 8 and the rear traveling wheel 10 are lift-type traveling wheels. The top of the arch formwork 3. Among the figure, 5 is the trestle bridge that enters trolley for slag truck, and 6 is track, all can continue to use prior art to arrange.

[0024] see Figure 4 The floating mechanism can be composed of ...

Embodiment 2

[0029] see Figure 7 -8, considering the situation that steel bars may need to be laid before the inverted arch pouring, in order to ensure the smooth forward movement of the trolley, an extension 25 can be set at the front end of the underframe of the trolley frame, and the front walking wheels 8 Mounted on the front end of the extension. Utilize this extended section to cross the next inverted arch pouring station of laying steel bar, make the front walking wheel 8 walk on the tunnel bottom surface before the next inverted arch pouring station. When walking, the front support seat 7 is upwardly folded and strides over the laid steel bar, so that the smooth forward movement of the trolley can be realized. Figure 6 is the track.

Abstract

The tunnel invert form board trolley, it belongs to the technology field of tunnel construction equipment. It includes the resist float platform, front walk wheel, back walk wheel, lift front, back supporting seat, cancelled structure trolley frame which contains column, the foundation frame of trolley and the invert form board set below the foundation frame of trolley, the said front, back supporting seat. And the front, back walk wheel are set in the end of the foundation frame of trolley, the resist float platform is set in the top of the invert form board, the said walk wheel are lift walk wheel, the said foundation frame of trolley is set above the invert form board by a float device. The merit is that the structure is simple, the cost of manufacture is low; the construction of the invert arch as well as upkeep and other work such as tunneling, slag, transportation can be in synchronously progress, and placing quality is not effected by the shocking of the vehicle. It is specially applied to the placing construction of long and big railway tunnel invert.

Description

technical field [0001] The invention relates to tunnel construction equipment. It particularly relates to a formwork trolley for pouring tunnel inverted arches. Background technique [0002] The lining and inverts shall be concreted after the excavation of the tunnel has been completed. The usual practice is to use a lining trolley to pour the lining, and the inverted arch and the inverted arch filling section are poured manually. The disadvantages of manual pouring of inverted arches are low efficiency and poor quality. It also affects that the excavation of the tunnel cannot be carried out in parallel with the pouring of the inverted arch. It also seriously interferes with other processes and operations, and cannot meet the construction requirements of long tunnels. In order to overcome this deficiency, the Chinese patent ZL03232894.X proposes a "tunnel full-ring integral molding lining formwork trolley", which mainly consists of a truss vierendeel frame beam, and a vehi...
