Description
Technical Field
The utility model relates to the technical field of hoisting equipment, in particular to a hoisting device for a hob and a cutter ring of a tunnel boring machine.
Background
With the rise of the shield construction method, the tunnel boring machine is widely applied. The hobbing cutter has an important role in tunnel construction, and because the hobbing cutter ring is worn and torn and the like and needs to be frequently replaced, the hob ring and the hobbing cutter need to be manually carried in a large amount in the assembling and maintaining process, so that the time and the labor are consumed.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention aims to provide a hoisting device for a hob and a cutter ring of a tunnel boring machine, which is convenient to use, reduces labor force, and improves carrying efficiency, in view of the defects of the prior art.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a tunnel boring machine hobbing cutter and hoist device for cutter ring, includes that hexagon bolt, cover establish lug on the hexagon bolt screw rod is pressed from both sides and is got the mechanism to and threaded connection are in locknut on the hexagon bolt.
According to the technical scheme, the clamping mechanism is sleeved on the screw rod of the hexagon bolt and can rotate, the hobbing cutter or the cutter ring is clamped through the clamping mechanism, the lifting lug is matched with the electric hoist or the crane to lift the hobbing cutter or the cutter ring to the set position, manual carrying of the hobbing cutter or the cutter ring is omitted, the workload of workers is reduced, and the working efficiency is improved.
Preferably, press from both sides and get mechanism including the cover establish jib I and jib II on the hex bolts, and set up the arcuation backup pad of jib I and II bottoms of jib. Adopt the arc backup pad can make its and hobbing cutter or cutter ring better cooperation, improve the laminating nature of snatching to hobbing cutter or cutter ring.
Preferably, the two ends of the outer side of the supporting plate are respectively provided with a baffle plate. The baffle prevents the hob or cutter ring from shifting during the transfer process.
Preferably, rubber pads are respectively arranged on the supporting plate and the baffle plate. Increase the frictional force between backup pad, baffle and hobbing cutter or the cutter ring, improve the fastness of snatching to hobbing cutter or cutter ring.
Preferably, handles are arranged on the outer sides of the two baffles. The relative position between the clamping mechanism and the hobbing cutter or the cutter ring is conveniently adjusted, and the handle is arranged outside the baffle plate to exert force better and control the clamping mechanism better.
Preferably, a proximity switch is provided at the rear end of the support plate. The proximity switch is used for controlling the relative position between the hob or the cutter ring and the baffle, so that the hob or the cutter ring is clamped between the two supporting plates, and the condition that the hob or the cutter ring falls off due to the fact that grabbing is not in place is prevented.
Preferably, a guide groove is formed inside the upper portion of the lifting lug. Make things convenient for lifting hook and lug on electric block or the crane to counterpoint fast, and the guide way plays limiting displacement to the lifting hook at the removal in-process, reduces the range of swaying of hobbing cutter or cutter ring.
The utility model has the beneficial effects that:
the automatic conveying device is simple in structure, strong in practicability, high in conveying efficiency, strong in stability and high in safety, reduces the labor amount of workers, and saves labor cost.

In the figure: 1 hex bolts, 2 lugs, 3 locknuts, 4 jib I, 5 jib II, 6 backup pads, 7 baffles, 8 rubber pads, 9 handles, 10 proximity switches, 11 guide ways, 12 hobbing cutters.
Detailed Description
The utility model is further described below with reference to the figures and examples.
As shown in fig. 1-4, a hoisting device for a hob and a cutter ring of a tunnel boring machine comprises a hexagon bolt 1, a lifting lug 2 and a clamping mechanism which are sleeved on a screw rod of the hexagon bolt 1, and a locknut 3 which is in threaded connection with the hexagon bolt 1. A guide groove 11 is arranged at the inner side of the middle part above the lifting lug 2.
The clamping mechanism comprises a suspender I4 and a suspender II 5 which are sleeved on the hexagon bolt 1, and an arc-shaped supporting plate 6 which is arranged at the bottoms of the suspender I4 and the suspender II 5. The two ends of the outer side of the supporting plate 6 are respectively provided with a baffle 7, and the supporting plate 6 and the baffle 7 are respectively provided with a rubber pad 8. Handles 9 are provided on the outer sides of the two shutters 7, and a proximity switch 10 is provided at the rear end of the support plate 6.
The working principle of the utility model is as follows: the lifting lug 2, the lifting rod I4 and the lifting rod II 5 are respectively sleeved on the screw rod of the hexagon bolt 1 and are blocked and limited by the locknut 3. The lifting lug 2 is lifted by a crane or an electric hoist to enable the suspender I4 and the suspender II 5 to be respectively positioned on two outer sides of the hobbing cutter 12 or the cutter ring, the hobbing cutter 12 or the cutter ring is clamped, the suspender I4 and the suspender II 5 are positioned by manual assistance, and therefore the hobbing cutter 12 or the cutter ring is lifted to a set position.
The apparatus elements referred to in the above embodiments are conventional apparatus elements unless otherwise specified, and the structural arrangements, operations, or controls referred to in the above embodiments are conventional in the art unless otherwise specified.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent substitutions made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
