Description

Technical Field

[0001] The utility model relates to the technical field of tunnel box culvert hoisting, in particular to a detachable integral box culvert hoisting device. Background Art

[0002] At present, large-diameter tunnels (≥10m) are mostly assembled with integral box culverts, and the technology of integral box culvert hoisting devices for large-diameter tunnels is relatively mature, which requires a large clearance in the shield machine trailer. The clearance in the large shield trailer can meet the space requirements of the existing integral box culvert hoisting device due to the large excavation diameter. However, there are few integral box culvert assembly projects in conventional tunnel construction (6m≤X≤10m), and due to the small excavation diameter, the clearance in the trailer is limited, which cannot better solve the space requirements of the existing integral box culvert hoisting device, and the technology is relatively short.

[0003] In the prior art, such as the patent for a method and device for lifting an integral box culvert with application number CN202111394692.9, a fixed claw is used. After the integral box culvert is transported to the appropriate position by marshaling, the claw needs to extend into the box culvert from the left and right sides. The gripping space is approximately greater than 1.8 times the thickness of the box culvert, which can meet the clearance in the shield machine trailer for the construction of large-diameter tunnels (≥10m). Conventional tunnels (6m≤X≤10m) have limited space, and the clearance in the shield machine trailer used for this type of tunnel cannot meet 1.8 times the thickness of the box culvert due to the limited clearance in the trailer. Therefore, it is necessary to design an integral box culvert lifting device suitable for the construction of conventional tunnels (6m≤X≤10m). Utility Model Content

[0004] In view of the deficiencies in the above-mentioned background technology, the utility model proposes a detachable integral box culvert lifting device, which solves the problem of difficulty and low efficiency in lifting the integral box culvert when the clearance in the shield machine trailer is insufficient in the conventional tunnel (6m≤X≤10m) construction in the prior art.

[0006] Further preferably, a rotary drive mechanism is detachably provided on the rope of the lifting hoist, and the rotary drive mechanism is detachably connected to the detachable claw mechanism; the rotary drive mechanism provides rotational power for the detachable claw mechanism in a horizontal plane.

[0007] Further preferably, the rotary drive mechanism includes a fixed frame connected to the lifting hoist, a slewing frame is rotatably provided on the fixed frame, the slewing frame is connected to a driving member arranged on the fixed frame, and the detachable claw mechanism is detachably connected to the slewing frame.

[0008] Further preferably, the detachable claw mechanism comprises a C-shaped structural frame, and a fixing piece and a connecting piece connected to the rotating frame are detachably provided on the upper crossbeam of the C-shaped structural frame. The C-shaped structural frame can be plugged and fixed to the box culvert member, and the fixing piece is used to stably connect the detachable claw mechanism in a non-working state to the box culvert member, and the connecting piece is used to realize rapid disassembly and assembly with the rotating frame.

[0009] Further preferably, the fixing member is a screw member or an oil cylinder member or an air cylinder member. When the fixing member is a screw member, the screw member is threadedly matched with a threaded through hole provided on the C-shaped structural frame.

[0010] Further preferably, the connecting piece is engaged with the rotating frame to achieve rapid disassembly and assembly with the rotating frame.

[0011] Further preferably, the connecting member is detachably connected to the rotating frame via a pin, so as to achieve rapid disassembly and assembly with the rotating frame.

The mobile frame 6 cooperates with the track beam 7 provided on the trailer 10 to form a moving pair, and the mobile frame moves along the track beam to realize the transportation of the integral box culvert. The mobile frame is used for the installation structure of the hoisting hoist; the track beam 7 is installed on the shield machine trailer, and the structure is stable, and the track beam is a carrier for bearing the mobile frame.

[0033] As a further preferred embodiment, the rope of the hoisting hoist 4 is detachably provided with a rotary drive mechanism 3, which is detachably connected to a detachable claw mechanism 1; the detachable claw mechanism is used to grab the integral box culvert. Under the action of the rotary drive mechanism, the detachable claw mechanism 1 can drive the integral box culvert to rotate and change the lifting posture of the integral box culvert.

[0034] like Figure 3 As shown, Example 2 is a detachable integral box culvert lifting device. Based on Example 1, this embodiment is preferred. The rotating drive mechanism 3 includes a fixed frame 31 connected to the lifting hoist 4, and the fixed frame is directly connected to the rope of the lifting hoist. A rotating frame 32 is rotatably provided on the fixed frame 31, and the rotating frame is connected to the fixed frame through a rotating member such as a bearing.

In specific implementation, the connector 1-2 is a shaft, and the slewing frame 32 is a cylinder with a buckle. The shaft and the cylinder are plug-fitted and fixed by the buckle, so as to achieve stable and fast assembly and disassembly.

[0038] In this embodiment, as a preference, the mobile frame 6 is provided with a running wheel 8 and a driving device 9 for driving the running wheel 8 to rotate.
