To the shield tail of shield mechanism to be entered to the hole of the borehole wall other side, and a distance is tunneled forward, so that stratum and positive endless tube piece
Between frictional force can offset shield machine promote generated reaction force, then the negative endless tube piece between reaction frame to shield tail at this time
Just complete mission, it is necessary to remove negative endless tube piece to accelerate construction efficiency, also provide conveniently for later construction.It constructs negative ring
Section of jurisdiction is the assembly inside shield machine, just needs to sling section of jurisdiction using crane when removing, is hung to ground and is decomposed.At present
Negative endless tube piece mostly uses reinforced concrete segment, and from great, and there are extruding force between negative endless tube piece, this extruding force is even super
The weight for crossing section of jurisdiction itself, it is very high to the requirement of mechanical strength of suspender, to reduce the security risk in lifting.
Utility model content
The purpose of this utility model is to provide a kind of for dismantling the suspender of negative endless tube piece, suspender machine with higher
The safety coefficient in negative endless tube piece hoisting process can be improved in tool intensity.
To achieve the above object, the utility model provides a kind of for dismantling the suspender of negative endless tube piece, including transmission rod, spiral shell
Female, reinforcing disk, floor and the lifting lug for being provided with hole for hoist；Transmission rod includes thread segment and smooth section；Nut is set in the spiral shell
In line section；Disk fixation is reinforced to be set in smooth section；Lifting lug and the transmission rod and reinforce disk and be fixedly connected, and transmission rod plus
Gu the axis of disk and lifting lug is overlapped；Floor reinforcement by connection disk and lifting lug are symmetricly set on the two sides of lifting lug, the ipsilateral floor of lifting lug
It is symmetricly set on the two sides of transmission rod.
Further, above-mentioned for dismantling the suspender of negative endless tube piece, it further include the backing plate being set on the transmission rod；Pad
Plate is between nut and section of jurisdiction.
Further, reinforcing disk is hollow structure, including the top plate and bottom plate and connection top plate that are oppositely arranged and bottom plate
Side.
Further, a plurality of stiffening plate is provided between top plate and bottom plate.
Further, transmission rod is round steel；Disk is reinforced to be welded by steel plate；Lifting lug and floor are steel plate, and floor is
Triangle.
The beneficial effects of the utility model are:
It is according to set Hoisting Program that loop wheel machine is in place, the hole for hoist of negative endless tube piece is drilled through using impact drill, is then pacified
Suspender is filled, transmission rod is inserted into inside section of jurisdiction on the outside of negative endless tube piece by drilling, backing plate is installed, nut is tightened, hangs for the first time
Two nuts are twisted when dress, two suspension centres are installed in every section of jurisdiction, and suspension centre is symmetrical arranged about the center of gravity of negative endless tube piece, installs and hang
After tool, loop wheel machine and suspender are connected by lifting rope, section of jurisdiction is hung to designated place, after section of jurisdiction steadily lands, nut is backed out, removes
Backing plate extracts transmission rod.The lifting that the above movement carries out next endless tube piece is repeated, to have commander special messenger in entire hoisting process.
Disk and floor are reinforced due to being provided with, the bonding strength between transmission rod and lifting lug is effectively strengthened, improves hoisting process
Coefficient is installed, and structure is simple, production easy to process and installing and dismounting.
Detailed description of the invention
Fig. 1 is provided by the embodiment of the utility model for dismantling the structural schematic diagram of the suspender of negative endless tube piece.
In figure: 1- transmission rod；2- nut；3- reinforces disk；4- floor；5- lifting lug；6- backing plate.
Specific embodiment
The present embodiment provides a kind of for dismantling the suspender of negative endless tube piece, including transmission rod 1, nut 2, reinforcing disk 3, floor
4 and it is provided with the lifting lug 5 of hole for hoist；Transmission rod 1 includes thread segment and smooth section；Nut 2 is set on thread segment；Reinforce disk 3
Fixation is set in smooth section；It lifting lug 5 and transmission rod 1 and reinforces disk 3 and is fixedly connected, and transmission rod 1, reinforce disk 3 and lifting lug 5
Axis is overlapped；4 reinforcement by connection disk 3 of floor and lifting lug 5, are symmetricly set on the two sides of lifting lug 5, and the ipsilateral floor 4 of lifting lug 5 is symmetrically set
It sets in the two sides of transmission rod 1, symmetrically to apply support force to reinforcing disk 3 and lifting lug 5.
Further, above-mentioned for dismantling the suspender of negative endless tube piece, it further include the backing plate 6 being set on transmission rod 1；Backing plate
6 between nut 2 and section of jurisdiction, reduces damage of the nut 2 to section of jurisdiction to the pressure of section of jurisdiction to disperse nut 2 in hoisting process.
Further, reinforcing disk 3 is hollow structure, including the top plate and bottom plate and connection top plate that are oppositely arranged and bottom plate
Side, with mitigate reinforce disk 3 weight.
Further, in order to improve the bonding strength for reinforcing disk 3, a plurality of stiffening plate is provided between top plate and bottom plate.
