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.

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 are installed 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

A tunnel inverted arch formwork trolley belongs to the technical field of tunnel construction equipment. Its composition includes anti-floating platform, front traveling wheels, rear traveling wheels, lift-type front and rear support bases, fasting platform frame with uprights, driving underframe and inverted arch formwork arranged under the driving underframe. The front and rear support bases and the front and rear running wheels are installed at both ends of the driving underframe, and the anti-floating platform is installed on the top of the trolley frame. The floating mechanism is installed above the inverted arch formwork. The advantage is that the structure is simple and the manufacturing cost is low; the pouring construction and maintenance of the inverted arch and other operations such as excavation and slag transportation can be carried out simultaneously, and the pouring quality is not affected by the vibration of passing vehicles. It is especially suitable for pouring construction of inverted arches of long railway tunnels.

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...
