Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering machinery technology, and in particular to a trestle device 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 trestle device that is simple in structure, low in cost, occupies less tunnel space, and has high construction continuity, which can be used for laying materials.

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

[0006] A trestle device for fabric placement 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. The transverse trolley is detachably connected to the mounting frame and is used to move the mounting frame to the side of the main bridge. The mounting frame is equipped with a concrete conveying mechanism. Fabric placement components for docking with the concrete conveying mechanism and support frames for supporting the mounting frame are provided on both sides of the main bridge. The support frames are equipped with support rollers for longitudinal movement of the mounting frame.

[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 front end of the mounting frame is detachably connected to the transverse trolley. A gantry is provided on the main bridge, and a rear transverse track is provided on the gantry above the main bridge. A rear transverse trolley is slidably mounted on the rear transverse track, and the rear end of the mounting frame is detachably connected to the rear transverse trolley.

[0010] The mounting frame is detachably connected to the transverse trolley and the rear transverse trolley via a lifting drive component.

[0011] The main bridge is equipped with longitudinally movable full-arc trolleys on both sides, which are used to transport the invert arch formwork.

[0012] 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.

[0013] The full-arc trolley is equipped with a traction component for pulling the mounting frame to move longitudinally.

[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 discloses a trestle device 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 is 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. The mounting frame is detachably connected to the lateral moving trolley. After the first construction area is poured, the mounting frame can be moved longitudinally to continuously pour multiple construction areas, resulting in a wider construction range and higher construction continuity. During operation, there is a certain distance between the lateral moving 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, allowing other vehicles on the main bridge to pass normally.

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

[0032] like Figures 1 to 7As shown, the trestle equipment for laying materials 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, and a passageway for vehicles to pass on the main bridge 1 is formed between the transverse track 11 and the main bridge 1. A transverse trolley 12 is movably mounted on the transverse track 11. The transverse trolley 12 is detachably connected to the mounting frame 2 and is used 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. The main bridge 1 has laying components 5 for docking with the concrete conveying mechanism and support frames 15 for supporting the mounting frame 2 on both sides. The support frames 15 are equipped with support rollers 16 for the mounting frame 2 to move longitudinally.

[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 first construction area on this side is poured by the concrete placement component 5. After the first 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 first construction area on the other side. After the first construction areas on both sides are poured, the mounting frame 2 is disconnected from the transverse trolley 12, the mounting frame 2 moves longitudinally to the second construction area, and the second construction area is poured according to the above steps, so that the continuous pouring of multiple construction areas can be achieved. The concrete-laying trestle of this embodiment can be used for laying concrete. By setting up 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 to lay concrete in the construction area on the other side of the main bridge 1. Only one set of mounting frame 2 and concrete conveying mechanism is needed to lay concrete on both sides of the main bridge 1. The structure is simple, the cost is low, and it occupies less tunnel space. The mounting frame 2 is detachably connected to the transverse trolley 12. After the first construction area is poured, the mounting frame 2 can be moved longitudinally to continuously pour multiple construction areas, which has a wider construction range and higher construction continuity. 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, such as Figure 1 and Figure 5 As shown, 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 is subjected to the buoyancy of the concrete slurry. The anti-floating device 6 can provide a vertically downward clamping force to the invert arch formwork 7. By integrating the transverse track 11 onto the anti-floating device 6, the structure is further simplified. The anti-floating device 6 can be any existing anti-floating device, which will not be described in detail here.

[0035] Furthermore, such as Figure 1 and Figure 6 As shown, in this embodiment, the front end of the mounting frame 2 is detachably connected to the transverse trolley 12. A gantry 17 is provided on the main bridge 1, and a rear transverse track 14 located above the main bridge 1 is provided on the gantry 17. A rear transverse trolley 18 is slidably mounted on the rear transverse track 14, and the rear end of the mounting frame 2 is detachably connected to the rear transverse trolley 18. The mounting frame 2 is moved by the front and rear supports of the transverse trolley 12 and the rear transverse trolley 18, resulting in a reliable structure and smoother movement. Disconnecting the mounting frame 2 from the transverse trolley 12 and the rear transverse trolley 18 allows the mounting frame 2 to move longitudinally on the supporting rollers 16, resulting in a simple and reliable structure.

[0036] Furthermore, such as Figure 5 and Figure 6 As shown, in this embodiment, the mounting frame 2 is detachably connected to the transverse trolley 12 and the rear transverse trolley 18 via a lifting drive component 21. When the lifting drive component 21 (e.g., a hydraulic cylinder) descends, it places the mounting frame 2 on the support rollers 16. Disconnecting the mounting frame 2 from the transverse trolley 12 and the rear transverse trolley 18 allows the mounting frame 2 to move longitudinally on the support rollers 16. Connecting the mounting frame 2 to the transverse trolley 12 and the rear transverse trolley 18, and raising the lifting drive component 21, lifts the mounting frame 2, allowing it to move laterally. The structure is simple and reasonable.

[0037] Furthermore, such as Figure 1 and Figure 5 As shown, in this embodiment, the main bridge 1 is equipped with longitudinally movable full-arc trolleys 13 on both sides. 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.

[0038] Furthermore, such as Figure 2 As shown, 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 mounted on the invert arch template 7, and the filling concrete placement component 52 is mounted on the full-arc trolley 13. Concrete is poured onto the invert arch through the invert arch concrete placement component 51, and the filling layer is poured 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 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.

[0039] Furthermore, such as Figure 3As shown, in this embodiment, the full-arc trolley 13 is equipped with a traction component for pulling the mounting frame 2 to move longitudinally. After the first construction area is poured, the full-arc trolley 13 is pulled to the second construction area by the traction component for pouring; by integrating the traction component onto the full-arc trolley 13, there is no need to set up a separate traction component, and the structure is simplified. Preferably, in this embodiment, the traction component is a buckle set on the full-arc trolley 13. By fastening the buckle to the mounting frame 2, the full-arc trolley 13 can be connected to the mounting frame 2, thereby realizing the traction of the mounting frame 2. Of course, in other embodiments, other forms of traction components can also be used.

[0040] Furthermore, such as Figure 1 As shown in this embodiment, multiple support rollers 16 are provided along the longitudinal direction, making the support more stable and reliable.

[0041] Furthermore, 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.

[0042] 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.

[0043] Furthermore, in this embodiment, the belt conveyor mechanism includes a conveyor belt 34, a plurality of longitudinally arranged first conveyor rollers 35, 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, and 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.

[0044] In particular, such as Figure 2 and Figure 4 As shown, in this embodiment, since both ends of the second concrete conveying assembly 4 are provided with second discharge ports 41 (when the second concrete conveying assembly 4 conveys materials in the forward direction, the second discharge port 41 at the front end discharges materials; when the second concrete conveying assembly 4 conveys materials in the reverse direction, the second discharge port 41 at the rear end discharges materials), after the second construction area is completed, there is no need to adjust the position of the mounting frame 2. The anti-floating device 6 and the inverted arch template 7 can be moved from the second discharge port 41 at one end of the second concrete conveying assembly 4 to the second discharge port 41 at the other end of the second concrete conveying assembly 4 by the full-arc trolley 13, so that the third construction area can be poured, and the construction efficiency is higher.

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.
