Description

Technical Field

[0001] This utility model relates to the field of tunnel trolley technology, specifically an integrated device for multi-face tunnel construction trestle and trolley. Background Technology

[0002] In tunnel drilling and blasting construction, invert filling and secondary lining are two crucial processes. The invert work area usually presents as a huge opening at the bottom of the tunnel (invert filling opening), which severely obstructs the construction passage. In order to ensure that the materials, equipment and vehicles for subsequent lining construction can pass through this work area smoothly, it is traditionally necessary to erect a special construction trestle.

[0003] Currently, construction sites commonly use independent trestle systems and independent lining trolleys. This separate operation mode has the following inherent drawbacks: First, the equipment has a single function and low efficiency in connecting processes. The trestle only serves the function of crossing and allowing traffic, while the lining trolley needs to be used independently behind or in front of the trestle for pouring. The two are used alternately in the limited space of the tunnel, which restricts each other, resulting in frequent process changes and time-consuming equipment entry, exit and positioning, which seriously restricts the overall construction progress.

[0004] Traditional trestle bridges cannot meet the needs of lining operations. Independent trestle bridges are only passageways, and their structural design does not consider providing a stable working platform for the lining trolley. If lining construction is to be carried out in the section covered by the trestle bridge, the trestle bridge must be moved away and the trolley must be in place before the operation can be carried out, or an additional complex support system must be built. This not only increases the construction cost, but also makes it extremely difficult to achieve rapid lining in the invert arch section. Utility Model Content

[0005] This utility model provides a multi-face tunnel construction trestle and trolley integrated device that can reliably cross the invert arch working area and provide a stable driving passage, and can also provide an immediately usable working platform for lining operations, thereby integrating the functions of passage and lining into one, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An integrated device for multi-face tunnel construction trestle and trolley includes a bridge chassis with drive wheels mounted on the bottom. It also includes a transverse sliding plate, a jacking mechanism, and two telescopic outriggers. Trolley side frames are fixedly mounted on both sides of the upper part of the bridge chassis, forming a passageway between the two side frames. Flip plates are movably hinged to both ends of the bridge chassis. Linear guide rails are fixedly mounted along the length direction on both sides of the bottom of the bridge chassis. The transverse sliding plate is slidably mounted at the bottom of the two linear guide rails, which drive the transverse sliding plate to move along the length direction of the linear guide rails. One end of each of the two telescopic outriggers is movably hinged to one end of the side of the transverse sliding plate. Hydraulic rods are movably hinged to both ends of the bottom of the transverse sliding plate, with the piston shaft of the hydraulic rods movably hinged to the telescopic outriggers. The jacking mechanism is mounted on the transverse sliding plate and is used to adjust the length of the telescopic outriggers.

[0007] As a preferred technical solution of this application, the telescopic outrigger includes a sleeve and a rod, one end of the sleeve is movably hinged to the transverse plate, and the rod is movably inserted into the sleeve.

[0008] As a preferred technical solution of this application, the pushing mechanism includes a movable block, a lead screw motor and a pull plate. A notch is provided in the middle of one side of the transverse plate. The movable block is hinged in the notch. One end of the lead screw motor is fixedly connected to the movable block. Both ends of the pull plate are fixedly connected to the middle of the insertion rod. A threaded hole is provided in the middle of the pull plate. The threaded rod of the lead screw motor is connected to the threaded hole.

[0009] As a preferred technical solution of this application, a slider is slidably provided on the linear guide rail, and the upper two ends of the transverse plate are respectively fixedly connected to the corresponding slider.

[0010] As a preferred technical solution of this application, lane plates are fixedly installed on both sides of the bottom of the vehicle passage.

[0011] As a preferred technical solution of this application, a roller is rotatably mounted on the outer end of the insertion rod.

[0012] The beneficial effects of this utility model are as follows: This utility model combines a trestle bridge with a trolley, and sets up a trolley side frame on the bridge chassis to facilitate construction. When the bridge chassis moves to the position of the invert arch filling opening, the hydraulic rod is activated to retract, causing the telescopic outriggers to tilt into the invert arch filling opening. The length of the telescopic outriggers is adjusted by the jacking mechanism so that the telescopic outriggers can contact the bottom of the invert arch filling opening, which can effectively prevent the bridge chassis from tilting and falling into the invert arch filling opening. At the same time, it is also convenient for the bridge chassis to move at the position of the invert arch filling opening. Construction vehicles can pass through the invert arch filling opening through the vehicle passage without the need to build a separate trestle bridge, which effectively saves costs and improves construction efficiency.

[0016] See Figures 1-3 As shown, this utility model provides an integrated device for multi-face tunnel construction trestle and trolley, including a bridge chassis 1, with drive wheels installed at the bottom of the bridge chassis 1, and also includes a transverse sliding plate 6, a jacking mechanism 8, and two telescopic outriggers 7. Trolley side frames 2 are fixedly installed on both sides of the upper part of the bridge chassis 1, forming a passageway 11 between the two trolley side frames 2. Flip plates 3 are movably hinged to both ends of the bridge chassis 1, and the flip plates 3 can be flipped to rest on the upper ends of the invert arch filling opening, facilitating the entry of construction vehicles into the passageway 11. Linear guide rails 5 are fixedly installed on both sides of the bottom along the length direction. The transverse plate 6 is slidably installed at the bottom position of the two linear guide rails 5. The linear guide rails 5 are used to drive the transverse plate 6 to move along the length direction of the linear guide rails 5. One end of the two telescopic legs 7 is movably hinged to the two ends of the side of the transverse plate 6. Hydraulic rods 4 are movably hinged to both ends of the bottom of the transverse plate 6. The piston shaft of the hydraulic rod 4 is movably hinged to the telescopic legs 7. The pushing mechanism 8 is installed on the transverse plate 6. The pushing mechanism 8 is used to adjust the length of the telescopic legs 7.

[0017] In this embodiment, the telescopic outrigger 7 includes a sleeve 71 and an insert rod 72. One end of the sleeve 71 is movably hinged to the transverse plate 6, and the insert rod 72 is movably inserted into the sleeve 71. The piston shaft of the hydraulic rod 4 is movably hinged to the sleeve 71. In the design, the hydraulic rod 4 is movably hinged to the bottom of the transverse plate 6 through a U-shaped seat, wherein the U-shaped seat is fixedly installed at the bottom of the transverse plate 6, thereby ensuring that the hydraulic rod 4 has a large deflection angle.

[0018] In this embodiment, the pushing mechanism 8 includes a movable block 81, a lead screw motor 82, and a pull plate 83. A notch is provided in the middle of one side of the transverse plate 6. The movable block 81 is hinged in the notch. One end of the lead screw motor 82 is fixedly connected to the movable block 81. Both ends of the pull plate 83 are fixedly connected to the middle of the insertion rod 72. A threaded hole is provided in the middle of the pull plate 83.

The length of the telescopic outrigger 7 is adjusted by the screw motor 82 so that its roller 9 can contact the bottom of the invert arch filling opening. The transverse plate 6 can be moved by the linear guide rail 5 so that the telescopic outrigger 7 can move to a suitable position in the invert arch filling opening, ensuring the stability of the bridge chassis 1 on the invert arch filling opening, while preventing the bridge chassis 1 from tilting and falling into the invert arch filling opening. Construction vehicles can pass through the invert arch filling opening through the vehicle passage 11.
