Description

Technical Field

[0001] The utility model relates to the technical field of secondary lining trolleys, in particular to a positioning formwork trolley for tunnel secondary lining pouring. Background Art

[0002] The trolley, full name lining trolley, is mainly used for tunnel, water diversion tunnel, secondary lining (second lining) concrete pouring, such as shield machine trolley, etc. The trolley is divided into two structures, one is the through-type and the other is the needle beam type. The trolley is mainly composed of a gantry and formwork. The gantry mainly bears the weight, and the formwork is designed according to the tunnel shape. It has the advantages of automatic walking and hydraulic automatic positioning and demoulding (it can move up, down, left and right).

[0003] Some trolleys cannot achieve quick positioning of the formwork and cannot guarantee the quality of the secondary lining. Even if it can be achieved, the structure is relatively complex. Therefore, a positioning formwork trolley for tunnel secondary lining pouring that can solve the above problems is needed. Summary of the Invention

[0004] The purpose of the utility model is to provide a positioning formwork trolley for tunnel secondary lining pouring according to the deficiencies of the above-mentioned prior art. The top formwork and side formwork are both connected to the gantry frame through lifting supports, and the side formwork is of a split design. The second side formwork of the side formwork is foldable, which is convenient for the overall movement of the trolley, thereby realizing the quick positioning of the formwork.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] A positioning formwork trolley for tunnel secondary lining pouring, characterized in that: the trolley includes a gantry frame, formwork, bottom beam, lifting support, telescopic support rod and retractable support. The formwork is composed of a top formwork and a side formwork. The side formwork includes a first side formwork connected to the top formwork and a second side formwork hinged to the first side formwork. The gantry frame is connected to the top formwork and the first side formwork through the lifting support. The bottom beams are respectively arranged below both sides of the bottom of the gantry frame. The bottom beams are connected to the second side formwork through the retractable support. The telescopic support rods are installed inside both sides of the bottom of the gantry frame, and the telescopic support rods are connected to the bottom beams.

[0007] Inner baffles are installed at the ends of the formwork. Outer baffles are arranged outside the inner baffles. A reserved clamping hole for installing a waterstop is formed between the outer baffles and the inner baffles.

[0008] Support seats are fixed on the trolley. The outer baffles and the support seats are connected through hydraulic telescopic rods. Both ends of the hydraulic telescopic rods are respectively hinged to the outer baffles and the support seats.

[0009] A fixed support and a trolley leg are successively installed at the bottom of the bottom beam.

[0010] The second side form is fixed to the ground by a ground screw.

[0011] The advantages of the present utility model are: simple structure and convenient operation; both the top form and the side form are connected to the gantry frame through lifting supports, and the side form is a split design, and the second side form of the side form is foldable, which is convenient for the overall movement of the trolley, thereby realizing the rapid positioning of the form.

[0016] The features of the present utility model and other related features are further described in detail below with reference to the accompanying drawings through embodiments for the understanding of those skilled in the same industry:

[0017] As Figures 1 to 4 shown, the marks in the figure are respectively represented as:

[0018] Gantry frame 1, bottom beam 2, lifting support 3, telescopic support rod 4, telescopic support 5, top form 6, first side form 7, second side form 8, fixed support 9, trolley leg 10, inner baffle 11, outer baffle 12, reserved clamping hole 13, support seat 14, hydraulic telescopic rod 15, arc plate 16.

[0019] Embodiment: As Figures 1 to 4As shown in the figure, this embodiment relates to a positioning formwork trolley for the secondary lining pouring of a tunnel. The trolley mainly includes a gantry frame 1, formwork, a bottom beam 2, lifting supports 3, telescopic support rods 4, telescopic supports 5, fixed supports 9, and trolley legs 10. The formwork consists of a top form 6 and side forms. The side forms include a first side form 7 connected to the top form 6 and a second side form 8 hinged to the first side form 7. In this embodiment, the first side form 7 and the second side form 8 are connected by a hinge. The gantry frame 1 is connected to the top form 6 and the first side form 7 through the lifting supports 3 for fine adjustment of the positions of the top form 6 and the first side form 7. There are two relatively arranged bottom beams 2, and the two bottom beams 2 are respectively arranged under both sides of the bottom of the gantry frame 1. The bottom beam 2 is connected to the second side form 8 through the telescopic support 5 for position adjustment of the second side form 8. The telescopic support rods 4 are installed inside both sides of the bottom of the gantry frame 1, and the telescopic support rods 4 are connected to the bottom beam 2 for rough adjustment of the positions of the top form 6 and the first side form 7. The fixed support 9 and the trolley legs 10 are successively installed at the bottom of the bottom beam 2 to play a supporting role. When the trolley is in the working state, the lifting supports 3, the telescopic support rods 4, and the telescopic supports 5 are all in the extended state, and the second side form 8 is fixed to the ground through the ground screw. When the trolley is in the non-working state, the lifting supports 3, the telescopic support rods 4, and the telescopic supports 5 are all in the contracted state, facilitating the movement of the trolley.

[0020] As Figures 1 to 4 shown, an inner baffle 11 is installed on the arc plate 16 of the trolley. An outer baffle 12 is provided on the outer side of the inner baffle 11. A reserved clamping hole 13 for installing a waterstop is formed between the outer baffle 12 and the inner baffle 11. A support seat 14 is fixed on the arc plate 16 of the trolley. The outer baffle 12 and the support seat 14 are connected by a hydraulic telescopic rod 15. Both ends of the hydraulic telescopic rod 15 are respectively hinged to the outer baffle 12 and the support seat 14. When installing the waterstop into the reserved clamping hole 13, the hydraulic telescopic rod 15 contracts, causing the outer baffle 12 and the inner baffle 11 to clamp the waterstop, preventing leakage during the pouring of the secondary lining and improving the quality of the secondary lining.

[0021] The beneficial technical effects of this embodiment are as follows: simple structure and convenient operation; both the top form and the side forms are connected to the gantry frame through the lifting supports, and the side forms are of a split design. The second side form of the side forms is foldable, facilitating the overall movement of the trolley, thereby realizing the rapid positioning of the formwork.

[0022] Although the above embodiments have described in detail the concept and implementation of the purpose of the present invention with reference to the accompanying drawings, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present invention without departing from the scope defined by the claims. Therefore, they are not elaborated one by one here.
