Abstract
The utility model discloses a combined type blade disc sword of backbreaking, including cutter (1), flexible hydro -cylinder (2) be connected with cutter (1), cutter (1) be fixed in blade holder (3) on, blade holder (3) are connected with flexible hydro -cylinder (2) through the round pin axle and are fixed, cutter (1) tear the sword for the heavy type, the sword of backbreaking install in the edge of combined type blade disc (4), be in same angle, same centre of a circle position with digging diameter orbit hobbing cutter. The utility model discloses operation convenient to use provides one kind and has stretched out and drawn back through the hydro -cylinder, replaces outermost orbit cutter excavation to a certain extent, and extension outermost orbit tool changing distance and the combined type blade disc sword of backbreaking who satisfies new hobbing cutter top installation space have improved the shield and has constructed the efficiency of construction.
Description
Technical field
The utility model relates to tunneling equipment field, is specifically related to a kind of combined type cutterhead and backbreaks cutter.
Background technology
Along with economic development, the quickening of urbanization process, the tunnels such as city underground, water conservancy and hydropower, highway, railway all need shield structure to excavate, and shield structure waits many advantages safely and fast with it and popularizes gradually.
Shield cutter in digging excavation process, outermost track hobboing cutter due to linear velocity maximum, tool wear is very fast, and cause digging diameter to reduce, time serious, shield body is by card, and the replacing cutter that opens a position need meet certain formation condition.
Therefore, provide one can play formation and carry out excavation effect, extend tool changing distance, improve efficiency of construction, simultaneously when replacing outermost track wearing and tearing cutter is new cutter, can necessarily dig in advance, meeting the novel device in the space needed for the installation of new cutter, has been a good problem to study.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art; the utility model provides a kind of flexible by oil cylinder; replace outermost track cutter excavation to a certain extent, extend outermost track tool changing Distance geometry and meet new hobboing cutter top installing space, the combined type cutterhead that improve shield-tunneling construction efficiency is backbreak cutter.
The purpose of this utility model is achieved in that
A kind of combined type cutterhead is backbreak cutter, comprises cutter 1, the telescopic oil cylinder 2 be connected with cutter 1;
Described cutter 1 is fixed on tool rest 3, and tool rest 3 is connected and fixed by bearing pin and telescopic oil cylinder 2;
Described cutter 1 is heavy tearing cutter;
Described cutter of backbreaking is installed on the edge of combined type cutterhead 4, is in same angle, same home position with digging diameter track hobboing cutter.
positive beneficial effect:the utility model is easy for operation; provide a kind of flexible by oil cylinder; replace outermost track cutter excavation to a certain extent, extend combined type cutterhead that outermost track tool changing Distance geometry meets new hobboing cutter top installing space and to backbreak cutter, improve shield-tunneling construction efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure be: cutter 1, telescopic oil cylinder 2, tool rest 3, combined type cutterhead 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of combined type cutterhead is backbreak cutter, comprises cutter 1, the telescopic oil cylinder 2 be connected with cutter 1;
Described cutter 1 is fixed on tool rest 3, and tool rest 3 is connected and fixed by bearing pin and telescopic oil cylinder 2;
Described cutter 1 is heavy tearing cutter;
Described cutter of backbreaking is installed on the edge of combined type cutterhead 4, is in same angle, same home position with digging diameter track hobboing cutter.
Described telescopic oil cylinder stroke is 50-75mm, when stroke is 75mm, can realize the maximum amount of the backbreaking 40mm of cutter.When combined type cutterhead 4 outermost track hob abrasion, when digging diameter reduces, stretched by telescopic oil cylinder 2, cutter 1 is extended, plays and necessarily digs effect; When replacing outermost track wearing and tearing hobboing cutter is new cutter, due to hob abrasion, digging diameter reduces, and new cutter installation headroom is not enough, and this cutter 1 stretches by telescopic oil cylinder, digs a part in advance, satisfied new cutter is in place.
The utility model is easy for operation, is stretched by oil cylinder, replaces outermost track cutter excavation to a certain extent, extends outermost track tool changing Distance geometry and meets new hobboing cutter top installing space, improve shield-tunneling construction efficiency.
Above embodiment is only for illustration of preferred embodiments of the present utility model; but the utility model is not limited to above-mentioned embodiment; in the ken that described exercising ordinary skill possesses; the any amendment done within spirit of the present utility model and principle, equivalently to substitute and improvement etc., it all should be encompassed within the technical scheme scope of the utility model request protection.
