Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering machinery technology, and in particular to a trestle that can be used for laying materials. Background Technology

[0002] In the construction of tunnel invert arch and filling layer concrete pouring, the common method is to park concrete mixer trucks on trestle bridges and use chutes for gravity-flow concrete placement. In practice, workers must manually adjust the truck's parking position and the chute length to achieve pouring in different areas. This fully manual operation mode has significant drawbacks: harsh construction environment: workers are exposed to a high-load, high-risk working environment for extended periods, posing a direct threat to their health; low efficiency: limited by the single-lane design and load-bearing capacity of the trestle bridges, only one mixer truck is allowed to operate during pouring, preventing other construction vehicles from passing.

[0003] Chinese patent document CN111997652A discloses a trestle bridge suitable for concrete placement in the tunnel invert and filling layers. The technical solution described in this document involves configuring mounting brackets on the main beams on both sides of the trestle bridge, and correspondingly installing a first concrete conveying assembly and a second concrete conveying assembly on each mounting bracket to achieve the pouring of the invert on both sides, avoiding the obstruction of the trestle bridge passage by concrete mixer trucks. However, this solution requires independent configuration of mounting brackets and two sets of concrete conveying mechanisms on both sides of the trestle bridge, resulting in a complex overall structure, high layout and maintenance costs, and a large amount of tunnel space occupied. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a simple, low-cost, and less tunnel space occupied trestle that can be used for laying fabric.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A trestle for fabric laying includes a main bridge, a mounting frame, and a transverse track. The transverse track is located above the main bridge, forming a passageway between the transverse track and the main bridge for vehicles to pass on the main bridge. A transverse trolley is movably mounted on the transverse track and is connected to the mounting frame to move the mounting frame to the side of the main bridge. The mounting frame is equipped with a concrete conveying mechanism, and fabric laying components for docking with the concrete conveying mechanism are provided on both sides of the main bridge.

[0007] As a further improvement to the above technical solution:

[0008] It also includes an anti-floating device, the transverse track is provided on the anti-floating device, and the bottom of the anti-floating device is connected to an arch template.

[0009] The main bridge is equipped with longitudinally movable full-arc trolleys on both sides, which are used to transport the invert arch formwork.

[0010] The fabric components include an inverted arch fabric component and a filling fabric component. The inverted arch fabric component is mounted on the inverted arch template, and the filling fabric component is mounted on the full-arc trolley.

[0011] The front end of the mounting frame is fixedly connected to the transverse trolley, and the rear end of the mounting frame is also equipped with casters.

[0012] The front end of the mounting frame is detachably connected to the transverse trolley, the rear end of the main bridge is provided with a rear transverse track, and the rear end of the mounting frame is also provided with rollers, which are located on the rear transverse track.

[0013] The mounting frame is detachably connected to the transverse trolley via a lifting drive component, and support frames are also provided on both sides of the main bridge to support the mounting frame.

[0014] The concrete conveying mechanism includes a first concrete conveying component and a longitudinally movable second concrete conveying component. The first concrete conveying component has a receiving port at its rear end and a first discharge port at its front end located above the second concrete conveying component. The second concrete conveying component has a second discharge port at both ends for docking with the material placing component.

[0015] Both the first concrete conveying assembly and the second concrete conveying assembly are belt conveyor mechanisms.

[0016] The belt conveyor mechanism includes a conveyor belt, a plurality of first conveyor rollers arranged longitudinally, and second conveyor rollers disposed on both sides of the first conveyor rollers. The first conveyor rollers and the second conveyor rollers on both sides form a U-shaped conveying structure with the opening facing outwards. The conveyor belt is wound around each of the first and second conveyor rollers.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This utility model relates to a trestle bridge for concrete placement. By setting up a laterally movable mounting frame, after the construction area on one side of the main bridge is poured, the mounting frame can be moved laterally to the other side of the main bridge to place the concrete in the construction area on the other side of the main bridge. Only one set of mounting frame and concrete conveying mechanism are needed to achieve concrete placement on both sides of the main bridge. The structure is simple, the cost is low, and it occupies less tunnel space. During operation, there is a certain distance between the lateral track and the main bridge to form a passage. The mounting frame and concrete conveying mechanism are located on the side of the main bridge, and other vehicles on the main bridge can pass normally.

[0019] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] like Figures 1 to 3 As shown, the trestle for laying concrete in this embodiment includes a main bridge 1, a mounting frame 2, and a transverse track 11. The transverse track 11 is located above the main bridge 1, forming a passageway between the transverse track 11 and the main bridge 1 for vehicles to pass on the main bridge 1. A transverse trolley 12 is movably mounted on the transverse track 11, and the transverse trolley 12 is connected to the mounting frame 2 to move the mounting frame 2 to the side of the main bridge 1. The mounting frame 2 is equipped with a concrete conveying mechanism, and laying concrete components 5 are provided on both sides of the main bridge 1 for docking with the concrete conveying mechanism. In this specification, "forward" refers to the tunnel excavation direction, "longitudinal" refers to the tunnel length direction, and "lateral" refers to the tunnel width direction.

[0033] In this embodiment, the trestle bridge that can be used for concrete placement is operated as follows: the main bridge 1 moves into position, the mounting frame 2 and the concrete conveying mechanism are located on one side of the main bridge 1, the concrete mixer truck is parked at the rear end of the concrete conveying mechanism for docking, the concrete is conveyed by the concrete conveying mechanism, and finally the concrete placement component 5 is used to pour the concrete for the area to be constructed on this side. After the area to be constructed on this side is poured, the mounting frame 2 is moved along the transverse track 11 by the transverse trolley 12 to the other side of the main bridge 1 to pour the concrete for the area to be constructed on the other side. The trestle bridge used for concrete placement in this embodiment uses a laterally movable mounting frame 2. After the construction area on one side of the main bridge 1 is poured, the mounting frame 2 can be moved laterally to the other side of the main bridge 1. Only one set of mounting frame 2 and concrete conveying mechanism is needed to place concrete on both sides of the main bridge 1. The structure is simple, the cost is low, and it occupies less tunnel space. During operation, there is a certain distance between the transverse track 11 and the main bridge 1 to form a passage. The mounting frame 2 and the concrete conveying mechanism are located on the side of the main bridge 1, and other vehicles on the main bridge 1 can pass normally.

[0034] Furthermore, this embodiment also includes an anti-floating device 6, with a transverse track 11 mounted on the anti-floating device 6. The bottom of the anti-floating device 6 is connected to the invert arch formwork 7. During the invert arch pouring, the invert arch formwork 7 will be subjected to the buoyancy of the concrete slurry. The anti-floating device 6 can provide a vertically downward clamping force for the invert arch formwork 7. By integrating the transverse track 11 onto the anti-floating device 6, the structure is further simplified. Of course, in other embodiments, the transverse track 11 can also be installed separately on a gantry welded to the main bridge 1. The anti-floating device 6 can be any existing anti-floating device, which will not be described in detail here.

[0035] Furthermore, in this embodiment, longitudinally movable full-arc trolleys 13 are provided on both sides of the main bridge 1. The full-arc trolleys 13 are used to transport the invert arch formwork 7. When the invert arch formwork 7 needs to be moved to the next construction area, the full-arc trolleys 13 lift and raise the invert arch formwork 7, which can then move the invert arch formwork 7 to the next construction area, achieving reuse. The overall structure is simple and reliable.

[0036] Furthermore, in this embodiment, the concrete placement component 5 includes an invert arch concrete placement component 51 and a filling concrete placement component 52. The invert arch concrete placement component 51 is disposed on the invert arch template 7, and the filling concrete placement component 52 is disposed on the full-arc trolley 13. Concrete is poured onto the invert arch through the invert arch concrete placement component 51, and onto the filling layer through the filling concrete placement component 52, thus realizing the pouring of the invert arch and the filling layer. The concrete placement component 5 can move synchronously with the full-arc trolley 13 and the invert arch template 7, reducing the number of concrete placement components 5 required and simplifying the structure. Preferably, in this embodiment, both the invert arch concrete placement component 51 and the filling concrete placement component 52 are concrete placement chutes.

[0037] Furthermore, in this embodiment, the front end of the mounting frame 2 is fixedly connected to the transverse trolley 12, and the rear end of the mounting frame 2 is also equipped with casters 23. When the mounting frame 2 moves laterally, the front end of the mounting frame 2 moves laterally via the transverse trolley 12, and the casters 23 at the rear end of the mounting frame 2 rotate 90°. As the transverse trolley 12 moves laterally, the mounting frame 2 can be moved to the other side of the main bridge 1. The mounting frame 2 is moved by the front and rear supports of the transverse trolley 12 and the casters 23, making the structure reliable and the movement more stable. Since the front end of the mounting frame 2 is fixedly connected to the transverse trolley 12, and the rear end of the mounting frame 2 is equipped with casters 23, when the full-arc trolley 13 moves the inverted arch formwork 7, it can move the anti-floating device 6 and the entire mounting frame 2 together, thus expanding the construction range.

[0038] like Figures 4 to 7As shown, in other embodiments, the front end of the mounting frame 2 is detachably connected to the transverse trolley 12, the rear end of the main bridge 1 is provided with a rear transverse track 14, and the rear end of the mounting frame 2 is also provided with rollers 22, which are mounted on the rear transverse track 14. The mounting frame 2 is moved by the front and rear supports of the transverse trolley 12 and the rollers 22, which makes the structure reliable and the movement more stable. Since the front end of the mounting frame 2 is detachably connected to the transverse trolley 12, the full-arc trolley 13 can move only the inverted arch template 7 and the anti-floating device 6 together, without moving the entire mounting frame 2, so that the position of the inverted arch template 7 and the anti-floating device 6 can be adjusted, and the load on the full-arc trolley 13 is lighter.

[0039] like Figure 5 As shown, in other embodiments, the mounting frame 2 is detachably connected to the transverse trolley 12 via a lifting drive component 21. Support frames 15 for supporting the mounting frame 2 are also provided on both sides of the main bridge 1. The lifting drive component 21 (e.g., a hydraulic cylinder) lowers to place the mounting frame 2 on the support frame 15. Disconnecting the mounting frame 2 from the transverse trolley 12 allows for subsequent adjustment of the positions of the inverted arch template 7 and the anti-floating device 6. Connecting the mounting frame 2 to the transverse trolley 12 and raising the lifting drive component 21 lifts the mounting frame 2, allowing for lateral movement of the mounting frame 2. This design is simple and reasonable.

[0040] Furthermore, such as Figures 1 to 3 As shown, in this embodiment, the concrete conveying mechanism includes a first concrete conveying assembly 3 and a longitudinally movable second concrete conveying assembly 4. The first concrete conveying assembly 3 has a receiving port 31 at its rear end and a first discharge port 32 located above the second concrete conveying assembly 4 at its front end. The second concrete conveying assembly 4 has second discharge ports 41 at both ends for docking with the placing component 5. During operation, the main bridge 1 moves into position, the concrete mixer truck is parked at the rear end of the first concrete conveying assembly 3 and docked with the receiving port 31, the second concrete conveying assembly 4 is moved to the corresponding placing component 5, and the first concrete conveying assembly 3 and the second concrete conveying assembly 4 are started. The concrete passes through the receiving port 31, the first concrete conveying assembly 3, the first discharge port 32, the second concrete conveying assembly 4 and the second discharge port 41 in sequence, and finally is poured into the construction area on this side by the placing component 5. After the construction area on this side is poured, the mounting frame 2 moves along the transverse track 11 via the transverse trolley 12 to the other side of the main bridge 1 to pour the construction area on the other side.

[0041] Furthermore, in this embodiment, both the first concrete conveying assembly 3 and the second concrete conveying assembly 4 are belt conveyor mechanisms. Belt conveying is stable and can effectively reduce the separation of concrete aggregate and mortar, ensuring the uniformity of concrete and construction quality.

[0042] Furthermore, such as Figure 3As shown, in this embodiment, the belt conveyor mechanism includes a conveyor belt 34, a plurality of first conveyor rollers 35 arranged longitudinally, and second conveyor rollers 36 disposed on both sides of the first conveyor rollers 35. The first conveyor rollers 35 and the second conveyor rollers 36 on both sides form an outward-facing U-shaped conveying structure. The conveyor belt 34 is wound around each of the first conveyor rollers 35 and the second conveyor rollers 36. Compared with the V-shaped conveying structure, the outward-facing U-shaped conveying structure has a larger conveying capacity, is less prone to clogging, and has a better conveying effect.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model using the methods and techniques disclosed above, or modify it into equivalent embodiments with equivalent changes, without departing from the spirit and technical solution of the present utility model. Therefore, any simple modifications, equivalent substitutions, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
