Problems solved by technology
[0003] At present, after the concrete used to support the existing tunnel lining trolley formwork is solidified, the formwork needs to be removed manually, that is, the gap between the formwork and the concrete is manually pried out, which increases the manual workload
Since the supporting devices of the formwork are not removed during manual prying, this removal method will increase the deformation of the formwork and affect the long-term cycle use of the formwork

Embodiment Construction
[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0027] Such as Figure 1-7 As shown, this embodiment proposes a tunnel lining trolley, the tunnel lining trolley includes a formwork 1 and a frame assembly 2, the frame assembly 2 can be used to support the formwork 1, specifically, the formwork 1 includes a top formwork 11. The first side formwork 12 and the second side formwork 13, the first side formwork 12 and the second side formwork 13 are respectively arranged on opposite sides of the top formwork 11, and the first side formwork 12 and the second side formwork 13 They are detachably connected to opposite ends of the top template 11 respectively. The frame assembly 2 includes a frame 21 on which at least one set of first hydraulic push rods 22 and at least one set of second hydraulic push rods 23 are arranged. The first hydraulic push rods 21 and the second hydraulic push rods 22 ar...

The invention belongs to the technical field of tunnel construction equipment, and discloses a tunnel lining trolley. The tunnel lining trolley comprises a formwork and a rack assembly used for supporting the formwork. The formwork comprises a top formwork, a first side formwork and a second side formwork. The rack assembly comprises a rack, at least one set of first hydraulic push rods, at leastone set of second hydraulic push rods and two sets of supporting frames, wherein guide rails and limiting baffles are arranged on the rack, third hydraulic push rods are arranged between the first side formwork and one group of supporting frames, fourth hydraulic push rods are arranged between the second side formwork and the other group of supporting frames, and an avoiding space is formed in thetop formwork. When the formwork needs to be dismantled, the first hydraulic push rods and the second hydraulic push rods retract by a certain distance, the rigidity of the first side formworks and the rigidity of the second side formworks are reduced, the third hydraulic push rods and the fourth hydraulic push rods push the supporting frames to slide, a gap is generated between the top formwork and formed concrete, and subsequent manual seam prying is avoided.
Description
technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and more specifically relates to a tunnel lining trolley. Background technique [0002] With the development of society, there are more and more constructions of tracks, roads and railways, which bring great convenience to people's life. In these constructions, many tunnels need to be excavated or constructed, and there is a construction method called lining in tunnel construction. Lining refers to a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the surrounding rock from deforming or collapsing. In the tunnel lining process in recent years, tunnel lining trolleys have been introduced. The tunnel lining trolley is mainly composed of formwork and brackets, the brackets are mainly used for load bearing, and the formwork is designed according to the shape of the tunnel to be lined.
