Description
Technical Field
The utility model belongs to the technical field of shield constructs quick-witted part jack-up hoist and mount, specific saying so relates to a detachable device that is used for shield to construct quick-witted cutterhead hoist and mount and stands up.
Background
The cutter head is used as a core component of the shield, is positioned at the foremost end of the shield machine, is a carrier of the cutter and has the functions of excavation, stabilization and stirring; in the process of manufacturing a cutter head of a new machine, the cutter head needs to be hoisted and turned over for a plurality of times according to the actual welding and assembling process. In addition, in the tunneling process of the shield tunneling machine, due to the fact that the working environment is severe, the cutter head bears large torque, large thrust and complex alternating load, abrasion and damage are prone to occurring, and generally, the shield tunneling machine needs to be maintained or repaired after one mark section is finished. In the process of maintaining or repairing the cutter head, the cutter head also needs to be hoisted and turned over for a plurality of times.
At present, at the in-process of tool setting dish hoist and mount and standing up, use two kinds of lug forms usually: 1. welded lug, this kind of lug has arranged two kinds of modes: (1) the lifting lugs are welded on the outer peripheral surface of the cutter ring of the cutter head, and the space of the wear-resisting plate of the cutter ring is occupied, so that the lifting lugs need to be planed before tunneling after the shield machine goes down the well, and the wear-resisting plate of the cutter ring is welded at the positions of the lifting lugs, so that the good tunneling function of the cutter head is met; (2) the lifting lugs are welded on the inner circumferential surface of the cutter head cutter ring, although the overall function of the cutter head is not affected by the mode, in the tunneling process of the shield tunneling machine, the flowing scouring of the slag soil or the broken stones can cause the abrasion or the damage of the lifting lugs, and further the function failure of the lifting lugs is caused. The use of the lifting lug can increase the welding and planing times per se, and the recycling times per se of the lifting lug is not high; in addition, the planing of the lifting lug can also damage the cutter head body. 2. The detachable lifting lug is used for lifting or turning over the cutter head by taking a certain position of the cutter ring of the cutter head as a lifting point. If the wear-resistant cutter ring with the embedded hard alloy is used as the cutter ring wear-resistant plate, the lifting lugs are easy to damage the hard alloy in the process of hoisting or turning over the cutter head.
Disclosure of Invention
In order to overcome the defects, the utility model provides a detachable device for shield constructs machine cutter head hoist and mount and stand up can satisfy the blade disc and tunnel the functional requirement, the lug subassembly that can dismantle again to realize new-built, the blade disc maintenance of blade disc and the hoist and mount of blade disc when entering the well or going out of the well, guaranteed lug subassembly's used repeatedly simultaneously.
The utility model discloses a solve the technical scheme that its technical problem adopted and be: a detachable device for hoisting and turning over a cutter head of a shield tunneling machine comprises a fixed base, a bolt, a washer, a lifting lug assembly and a plug, wherein the fixed base is welded and fixed on a cutter head body of the shield tunneling machine and is positioned on the inner side of a cutter ring of the cutter head; the fixed base is provided with a plurality of threaded holes, and when the lifting lug assembly is not installed, a plug is correspondingly screwed into each threaded hole; the lifting lug assembly is correspondingly provided with a mounting hole, when the cutter head of the shield machine needs to be hoisted and turned over, the lifting lug assembly is fixed on the fixed base through bolts and washers after corresponding to the mounting hole on the lifting lug assembly and the threaded hole on the fixed base, and the lifting hole of the lifting lug assembly after installation is positioned on the outer side of the cutter head cutter ring.
As a further improvement, unable adjustment base is square board, and the four corners sets up the chamfer structure, the screw hole is four, is located this unable adjustment base's four corners.
As a further improvement, the mounting hole on the lug assembly with screw hole one-to-one on the unable adjustment base sets up, when installing the lug assembly, each a screw in bolt extremely in the mounting hole the screw is downthehole to it is equipped with the packing ring to correspond between the nut of bolt and the lateral surface of mounting hole.
The utility model has the advantages that: 1) the detachability of the lifting lug ensures the cyclic utilization of the lifting lug; 2) the installation is simple, and the disassembly is convenient; 3) the damage of other lifting lug types to the cutter head body is effectively avoided.

Detailed Description
The following description of a preferred embodiment of the present invention will be made in conjunction with the accompanying drawings.
Referring to fig. 1-4, for the utility model discloses a detachable device for shield constructs machine cutterhead hoist and mount and stand up, including unable adjustment base 1, bolt 2, packing ring 3, lug assembly 4 and end cap 5.
The fixed base 1 is welded and fixed on a cutter head body 6 of the shield tunneling machine and is positioned on the inner side of a cutter head cutter ring 7, the thickness of the fixed base does not affect the aperture ratio parameter of the cutter head, the design requirement of the shield tunneling machine is met, and the good tunneling function of the shield tunneling machine is guaranteed.
Lifting lug assembly 4 passes through bolt 2, packing ring 3 to be fixed on unable adjustment base 1, in order to guarantee that the blade disc possesses the requirement of standing up at the in-process of hoist and mount, need extend lifting eye 4's hoist and mount hole outside the blade disc cutter ring.
In the process of tunneling construction after the shield tunneling machine goes into the well, the plug 5 needs to be screwed into the threaded hole of the fixed base 1, so that the situation that the threads are damaged by the slag or broken stones cut by the cutter head in the tunneling construction process of the shield tunneling machine, and the installation of the lifting lug assembly 4 is further influenced is avoided.
Therefore, the utility model discloses can satisfy the blade disc tunnelling functional requirement, the lug assembly that can dismantle again to realize the hoist and mount when the blade disc is newly made, blade disc maintenance and blade disc enter the well or go out the well, guaranteed lug assembly's used repeatedly simultaneously.
