Description

Technical Field

[0001] The utility model relates to the technical field of disassembly assistance, in particular to a device for disassembly assistance in a shield machine tunnel. Background Art

[0002] A shield machine is a tunnel boring machine that uses the shield method. The shield construction method is that the tunnel boring machine builds (lays) the "shield" (referring to the supporting segments) of the tunnel while excavating, which is different from the open construction method. Internationally, the broad shield machine can also be used in rock formations, but it is different from the open (non-shield method) tunnel boring machine. In my country, tunnel boring machines used in soft soil formations are usually called (narrow sense) shield machines, and those used in rock formations are called (narrow sense) TBMs. Shield machines are generally divided into hand-dug shields, extrusion shields, semi-mechanical shields (local air pressure, global air pressure), and mechanical shields (open-chest cutting shields, air pressure shields, mud-water pressure shields, earth pressure balance shields, mixed shields, and special-shaped shields) according to their working principles. Shield machines usually require auxiliary equipment when dismantling the tunnel.

[0003] For example, a Chinese authorized patent with announcement number CN218708782U is a shield machine in-tunnel disassembly system, which includes a shield machine shield shell, equipment to be dismantled, a battery car and a main pipe piece car. A plurality of first lifting ears are welded to the upper part of the inner part of the shield machine shield shell, and a hand chain hoist is connected to the first lifting ear. The equipment to be dismantled is provided with a plurality of second lifting ears, and the other end of the hand chain hoist is connected to the second lifting ear. The main pipe piece car is located at a position opposite to the equipment to be dismantled, and a portal frame is fixedly installed on the main pipe piece car, and the battery car drives the main pipe piece car to move. The utility model provides a shield machine in-tunnel disassembly system, which solves the problem that the internal space of the shield machine is small and most of the equipment is large in size or heavy, and it is impossible to rely on large-scale lifting equipment, resulting in great difficulties in lifting and transportation during dismantling.

[0004] The above-mentioned traditional disassembly equipment uses lifting equipment to take out the disassembled materials, which is time-consuming and labor-intensive during transportation. Mobile racks are generally used for mobile transportation, but the mobile racks have a high height and the materials are heavy, which makes it inconvenient for workers to carry and place them on the mobile racks. This is time-consuming and labor-intensive during use, affecting the material handling efficiency. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example

[0030] Reference Figure 1-6 As shown, a shield machine in-hole disassembly auxiliary device includes a moving plate 1, and four groups of moving wheels 220 are fixed at the bottom of the moving plate 1. The four groups of moving wheels 220 are respectively installed at the four corners of the moving plate 1. The arrangement of the moving wheels 220 can facilitate the moving plate 1 to carry the disassembled object and move, and the operation is more comfortable. Two groups of side plates 211 are fixed on the top of the moving plate 1, which are relatively distributed. The inner walls of the two groups of side plates 211 are connected to the support plate 212 through an adjustment mechanism. The use height of the support plate 212 can be stably controlled by the adjustment mechanism, which is convenient for supporting and placing disassembled objects of different heights. The disassembled objects can be placed on the support plate 212 and the moving plate 1. The outer wall of the support plate 212 is rotatably connected to a rotating frame 214, and the inner wall of the rotating frame 214 is rotatably connected to a plurality of rotating columns 215. The outer walls of the plurality of rotating columns 215 are fixed with anti-skid layers 216. The anti-skid layers 216 can be made of rubber material, which has a good wear resistance effect, ensuring that the disassembled objects will not fall off, and can also prevent the disassembled objects from being worn and damaged. By pushing the disassembled object to be transported to the support plate 212 along the tilting direction of the rotating frame 214, the anti-skid layer 216 will roll, and the friction force of the tilting movement can be converted into rolling friction, thereby achieving the effect of saving driving force and enhancing the transportation efficiency of the equipment. Two groups of fixed plates 213 are fixed to the outer wall of the support plate 212, and the rotating frame 214 is rotatably connected between the two groups of fixed plates 213. The rotating frame 214 can rotate stably relative to the two groups of fixed plates 213, which can facilitate the rise of the disassembled object when in use. After the disassembled object is transported to the top of the support plate 212, the rotating frame 214 can be flipped upward to prevent the disassembled object from falling.

[0031] A vertical plate 217 is fixed to one side of the fixed plate 213 away from the rotating frame 214. The inner wall of the vertical plate 217 is threadedly connected to a limit bolt 218. The outer wall of the rotating frame 214 is provided with a screw hole 219 that matches the thread of the limit bolt 218. When the rotating frame 214 is in a vertical state, Figure 5-6 As shown, by rotating the limiting bolt 218 so that the limiting bolt 218 is threadedly connected with the screw hole 219, the rotating frame 214 is locked to ensure that the rotating frame 214 will not fall off, and it can also prevent the disassembled objects from falling during transportation, making the operation more efficient.

[0032] A first sliding block 312 is fixed to the outer wall of the support plate 212, and a first sliding groove 311 is vertically distributed and slidably matched with the first sliding block 312 on the inner wall of the side plate 211. The support plate 212 can move vertically under the action of the first sliding block 312 and the first sliding groove 311, which is convenient for transporting disassembled objects of different heights.

[0033] The adjusting mechanism includes a threaded sleeve 316, a hinge rod 317, a block 318, a fixed sleeve 319, a slot 320 and a driving component. The threaded sleeve 316 is connected to the bottom of the support plate 212 through the driving component. The outer wall of the threaded sleeve 316 is hinged with a block 318 through the hinge rod 317. A plurality of groups of vertically distributed fixed sleeves 319 are fixed to the outer wall of the side plate 211. A slot 320 corresponding to the block 318 is provided inside the plurality of groups of fixed sleeves 319. The threaded sleeve 316 is driven by the driving component to move closer to or away from the middle position of the support plate 212, thereby driving the hinge rod 317 to rotate and pushing the block 318 in and out of the slot 320 inside the fixed sleeve 319. When the block 318 is disengaged from the slot 320, the support plate 212 can be moved up and down to adjust the position of the support plate 212. Under the operation of the driving component, the block 318 is driven to be inserted into the slot 320 again to achieve the locking purpose. A second sliding block 321 is fixed to the top of the card block 318, and a second sliding groove 322 is opened at the bottom of the support plate 212 to slide with the second sliding block 321. The second sliding block 321 and the second sliding groove 322 ensure that the card block 318 moves more stably, so that it can accurately enter and exit the card slot 320.

[0034] The driving component includes a first connecting plate 313, a screw rod 314, and a second connecting plate 315. The first connecting plate 313 and the second connecting plate 315 are fixed to the bottom end of the support plate 212. The screw rod 314 is rotatably connected between the first connecting plate 313 and the second connecting plate 315, and the outer wall is threadedly connected to the threaded sleeve 316. The screw rod 314 is rotated, and the threaded sleeve 316 is driven to reciprocate close to or away from the middle position of the support plate 212 under the action of the thread, thereby achieving a stable driving effect and making the operation more efficient.

[0035] Working principle: When it is needed, the heavy object is pushed along the direction of the rotating frame 214 to make the anti-skid layer 216 and the rotating column 215 roll, which achieves a time-saving and labor-saving transportation effect. The material can be transported to the support plate 212 for support, and then the rotating frame 214 is rotated to drive the rotating column 215 and the anti-skid layer 216 to flip upward, and the limiting bolt 218 is made to correspond to the screw hole 219. By rotating the limiting bolt 218, the limiting bolt 218 can be threadedly connected with the screw hole 219 under the action of the thread, and the position of the rotating frame 214 can be locked to ensure that the rotating frame 214 will not tilt. The rotating frame 214 can protect the material and ensure that the material will not fall off.

[0036] When the height of the support plate 212 needs to be adjusted, the threaded sleeve 316 is moved to the side close to the middle position of the movable plate 1 by rotating the screw rod 314 forward, and the hinge rod 317 is driven to rotate, thereby pushing the block 318 to disengage from the slot 320 inside the fixed sleeve 319, and then the support plate 212 is pulled upward to drive the first sliding block 312 to slide inside the first sliding slot 311. When the block 318 corresponds to another set of slots 320, after the screw rod 314 is rotated in the opposite direction, the threaded sleeve 316 is driven to move away from the middle position of the movable plate 1 under the action of the thread, so that the hinge rod 317 rotates again, and pushes the block 318 to be inserted into the slot 320, thereby achieving the effect of locking the support plate 212.
