Description

Technical Field

[0001] The utility model relates to tunnel construction equipment, in particular to a trestle bridge which is convenient for laying materials. Background Art

[0002] In recent years, my country has made significant progress in concrete spreading technology, placing higher demands on construction efficiency and quality. During the construction of tunnel invert fill layers, the existing method of pouring concrete primarily involves distributing concrete from one or more distribution chutes on either side of the trestle main beam. These chutes have a limited coverage area, preventing direct concrete spreading in large areas in the middle of the tunnel. Filling relies on the concrete's inherent fluidity, requiring manual labor to distribute the concrete throughout the fill layer. This increases labor intensity and compromises distribution efficiency. Furthermore, the installation of multiple distribution chutes also increases equipment costs. Utility Model Content

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] Figures 1 to 7 An embodiment of a material distribution trestle of the present invention is shown. The material distribution trestle of this embodiment includes a passage structure 1 and a material distribution chute 2, a hopper 3, a rotating guide rail 4, and a movable carriage 5 disposed on the rotating guide rail 4. The hopper 3 is disposed between the passage structures 1 on both sides, the rotating guide rail 4 is disposed below the passage structure 1, the material distribution chute 2 is rotatably connected to the discharge port of the hopper 3, and the movable carriage 5 is connected to the material distribution chute 2. Preferably, the trestle includes two rows of main beams 11 and a cross beam 12 disposed between the two rows of main beams 11. The passage structure 1 is disposed at both ends of the cross beam 12, and the rotating guide rail 4 is mounted on the underside of the cross beam 12.

[0034] The embodiment of the present invention is convenient for distributing materials. When pouring the filling layer concrete, the concrete tanker can drive onto the passage structure 1 and discharge the concrete into the hopper 3. The concrete is distributed through the hopper 3 and the distribution chute 2 in sequence. The area in the middle of the tunnel can be directly distributed. The mobile trolley 5 can move along the rotating guide rail 4, thereby driving the distribution chute 2 to rotate relative to the hopper 3, realizing 360° all-round distribution ( Figures 1 to 2 The figure shows the case where the material distribution chute 2 is rotated 180 degrees to distribute the material.

[0035] Furthermore, in this embodiment, a first cylinder 31 is provided at the discharge port of the hopper 3, and a second cylinder 21 is provided at one end of the distribution chute 2. The second cylinder 21 is rotatably connected to the first cylinder 31. The connection between the first cylinder 31 and the second cylinder 21 facilitates the relative rotation of the distribution chute 2 relative to the hopper 3.

[0036] See Figure 5 and Figure 6 Furthermore, in this embodiment, a first connecting rod 51 is provided between the second cylinder 21 and the movable carriage 5, and a second connecting rod 52 is provided between the first connecting rod 51 and the other end of the material distribution chute 2. The movable carriage 5 applies a driving force to both ends of the material distribution chute 2 via the first connecting rod 51 and the second connecting rod 52, thereby facilitating the rotation of the material distribution chute 2 around the first cylinder 31. This provides a reasonable and reliable structure.

[0037] Furthermore, in this embodiment, a slider 53 is provided on the first connecting rod 51 for driving the material distribution chute 2 to swing up and down. One end of the material distribution chute 2 is hinged to the second cylinder 21, and one end of the second connecting rod 52 is hinged to the slider 53, while the other end of the second connecting rod 52 is hinged to the other end of the material distribution chute 2. When the slider 53 slides along the first connecting rod 51, the second connecting rod 52 can drive the material distribution chute 2 to swing up and down, making it easier to adjust the inclination angle of the material distribution chute 2 and achieve more refined material distribution. At the same time, when not in use, the material distribution chute 2 can be swung upward for storage, reducing space occupation.

[0038] As a preferred embodiment, a locking structure is provided between the slider 53 and the first connecting rod 51. This locking structure secures the slider 53 to the first connecting rod 51, preventing the material distribution chute 2 from accidentally swinging and further improving reliability. Specifically, multiple locking holes can be provided at intervals on the first connecting rod 51, and at least one locking hole can be provided on the slider 53. After the locking holes are aligned, the two can be locked using a locking pin, bolt, or the like. Alternatively, a removable stopper can be provided on the first connecting rod 51 to prevent the slider 53 from accidentally sliding.

[0039] As a preferred embodiment, the first connecting rod 51 is provided with a sliding drive 54 for driving the slider 53 to slide, further improving the automation and intelligence of the device. The sliding drive 54 can be, for example, an air cylinder, an oil cylinder, a screw-nut pair, etc., which will not be described in detail.

[0040] See Figure 7 Furthermore, in this embodiment, a radial flange 32 is provided on the first cylinder 31, and a hook portion 22 is provided on the second cylinder 21, which is connected to the radial flange 32. The hook portion 22 cooperates with the radial flange 32 to strengthen the connection between the second cylinder 21 and the first cylinder 31, preventing the second cylinder 21 from separating from the first cylinder 31 due to the gravity of the material distribution chute 2 and the impact of concrete, further improving reliability.

[0041] See Figure 7 Furthermore, in this embodiment, U-shaped slots 33 are provided on both sides of the hopper 3. The U-shaped slots 33 are clamped on the passage structure 1, so as to facilitate the reliable positioning and installation of the hopper 3 on the passage structure 1 on both sides. Of course, in other embodiments, the hopper 3 can also be installed on the passage structure 1 by fasteners such as bolts and screws.

[0042] Preferably, the top surface of the hopper 3 is substantially flush with the top surface of the passage structure 1 , which helps to avoid collisions with construction vehicles and equipment passing on the passage structure 1 .

[0043] Preferably, the hopper 3 and the material distribution chute 2 are set to two and distributed along the length direction of the passage structure 1, and arranged one to one (correspondingly, the rotating guide rail 4 and the moving trolley 5 are also set to two), which can make full use of the space in the length direction of the trestle and further improve the efficiency of material distribution.

[0044] Furthermore, in this embodiment, the distribution chute 2 is a telescopic structure. By extending and retracting the distribution chute 2, the length of the distribution chute 2 can be adjusted, thereby adjusting the distribution area and further increasing the distribution coverage. Specifically, the distribution chute 2 can be a two-section structure, with one section having multiple first mounting holes along its length and the other section having at least one second mounting hole. By aligning the second mounting holes with different first mounting holes and locking them with bolts, pins, etc., the overall length of the distribution chute 2 can be adjusted, resulting in a simple structure and convenient use. Alternatively, the two sections can be connected by elongated holes in combination with fasteners such as bolts to achieve telescopic adjustment.

[0045] Example 2

[0046] Figure 8 Another embodiment of the trestle for facilitating material distribution of the present invention is shown. The trestle for facilitating material distribution of this embodiment is basically the same as that of the first embodiment, except that:

[0047] The material distribution trestle of this embodiment eliminates the slider 53 and the sliding drive 54 of the first embodiment. By installing second connecting rods 52 of different lengths, the inclination angle of the material distribution chute 2 can also be adjusted. Compared with the first embodiment, the structure is simplified and the corresponding cost is reduced.
