Description
Technical Field
The utility model relates to a tunnel construction machines, in particular to hoist device is demolishd to burden ring canal piece.
Background
In the period that the infrastructure of China enters rapid development, subway tunnels, high-speed rail tunnels, highway tunnels and municipal tunnels bloom like bamboo shoots in the spring after rain, and shield construction is more and more widely applied along with the construction of each tunnel.
The shield construction mainly comprises three stages of shield initiation, shield tunneling and shield receiving. The negative ring pipe piece is required to be used in the shield starting stage, after the shield starting is finished, the negative ring pipe piece needs to be dismantled, and the negative ring pipe piece is large in size and heavy in weight, and is located at a high altitude in the dismantling process, so that the dismantling of the negative ring pipe piece is always a great hazard source.
In order to enable the negative ring pipe piece to be dismantled more safely, the negative ring pipe piece dismantling lifting appliance is designed aiming at the negative ring pipe piece dismantling through carefully researching the structure of the negative ring pipe piece, and the negative ring pipe piece dismantling lifting appliance is simple in operation, safe, reliable and high in efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a hoist device is demolishd to anion pipe piece is provided to effectively improve the anion pipe piece and demolish effectively, safe and reliable moreover.
The utility model provides a technical scheme that its technical problem adopted as follows:
the utility model discloses a hoist device is demolishd to burden ring canal piece, characterized by: the device comprises a carrying pole beam and a hanging ring hung in the center of the carrying pole beam, wherein adjusting holes are formed in the length direction of the carrying pole beam at equal intervals, two inverted chains are symmetrically installed on the carrying pole beam at intervals, the upper ends of the inverted chains are hooked on the adjusting holes corresponding to the positions of field negative ring pipes, the lower ends of the inverted chains are hooked with lifting lugs, and piercing bolts sleeved with plugging plates are installed on the lifting lugs.
The beneficial effects of the utility model are that, compare traditional negative ring canal piece and demolish, use this negative ring canal piece hoist to demolish the negative ring section of jurisdiction, not only easy operation, safe and reliable demolishs efficiently, and this hoist simple manufacture.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1 and 2, the utility model discloses a hoist device is demolishd to burden ring pipe piece includes that shoulder pole roof beam 2 sets up in its central rings 1 with hanging, the equidistant interval of length direction of shoulder pole roof beam 2 has seted up regulation hole 3, and two back strands 4 of interval symmetry installation on shoulder pole roof beam 2, 4 upper ends of back strands hook on with on-the-spot burden ring piece position corresponding regulation hole 3, 4 lower extreme hooks of back strand are used for connecting the lug 5 of fixed burden ring pipe piece, install the cover and are equipped with the cross-core bolt 6 of end plate 7 on the lug 5.
Referring to fig. 6, the flying ring 1 is a strong ring capable of bearing a load of 30T, the shoulder pole beam 2 is generally manufactured by processing a steel plate with a thickness of 4cm, the number of the adjusting holes 3 is generally 20, and the diameter is phi 50 mm. The function of the chain block 3 is to keep the shoulder pole beam 2 in a horizontal state by adjusting the length of the chain block 3 in addition to providing enough tension. The lifting lugs 5, the through bolts 6 and the plug plates 7 are used for connecting and fixing the negative ring duct piece. The through bolt 6 is a high-strength bolt, and the damage of various pulling forces and shearing forces in the process of dismantling the negative ring pipe piece is met.
When a negative ring duct piece is removed, a proper hole is respectively drilled in the positions of grouting holes in two sides of the negative ring duct piece by a water drill, a piercing bolt 6 sequentially penetrates through a lifting lug 5, a duct piece grouting hole and a plugging plate 7, a nut is screwed, a hook at the lower part of a chain block 4 is hung, a hook at the upper part of the chain block 4 selects and hangs a proper adjusting hole 3 according to the distance between the two lifting lugs 5, the length of the chain block 4 is adjusted, a shoulder pole beam 2 is in a horizontal state, the chain block 4 is tensioned, the duct piece bolt is removed, and the hoisting ring 1 is slowly lifted
The above is only used for illustrating some principles of the negative ring pipe piece dismantling lifting device of the present invention, and it is not intended to limit the present invention to the specific structure and the application range shown and described, so all the corresponding modifications and equivalents that may be utilized all belong to the patent scope applied by the present invention.
