Abstract
The utility model discloses a cleaning device of a tool bit of a shield tunneling machine. The cleaning device comprises an upper cross rod and a lower cross rod, wherein a connecting rod which can be used as a handle simultaneously is vertically connected between the middle part of the upper cross rod and the middle part of the lower cross rod, one end of the upper cross rod extends outwards to form a flat-head chisel, and one end of the lower cross rod extends outwards to form a pike. The cleaning device of the tool bit of the shield tunneling machine is simple in structure, convenient to use, capable of effectively cleaning stone chippings which are attached to the tool bit and pebbles which are embedded between the tool bits by being matched with a hammer to be used, and capable of guaranteeing the tool bit to be in the best working state, and meanwhile, the service life of the tool bit is prolonged.
Description
Technical field
The utility model relates to shield machine appurtenance field, is specifically related to a kind of shield machine cutter head cleaning plant.
Background technology
Shield machine is widely used in the tunneling field, it can improve the excavation progress in tunnel greatly, but when excavating sand and gravel stratum, the phenomenon of cobble usually occurs being embedded with on the cutter head or between the cutter head, because cobble has the characteristic of high rigidity, can reduce the stress of cutter head greatly, and running can very easily make cutter head burst apart for a long time, thereby reduce whole operating efficiency, and the further directly wearing and tearing of meeting knife rest in the back tunneling process that bursts apart, thereby loss increased.
The utility model content
The utility model purpose provides a kind of shield machine cutter head cleaning plant, and it can solve existing problem in the background technology effectively.
In order to solve existing problem in the background technology, it comprises cross tube and sheer pole, the vertical connecting rod that is connected with the double as handle between the middle part of described cross tube and sheer pole, an end of described cross tube extend outward the homalocephalus cutter, and an end of described sheer pole extends outward hammer drill.
Owing to adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, easy to use, can and being used of hammer under effectively cleaning be attached to the aggregate chips on the cutter head and be embedded in cobble between the cutter head, can when guaranteeing that cutter head is in optimum Working, improve the service life of cutter head.
Description of drawings
In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing embodiment is done simple introduction.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with among the utility model embodiment is clearly and completely described the technical scheme among the utility model embodiment.
Referring to Fig. 1, this specific embodiment is to be achieved by the following technical solutions, it comprises cross tube 1 and sheer pole 2, the vertical connecting rod 3 that is connected with the double as handle between the middle part of described cross tube 1 and sheer pole 2, one end of described cross tube 1 extends outward homalocephalus cutter 4, and an end of described sheer pole 2 extends outward hammer drill 5.
Owing to adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, easy to use, can and being used of hammer under effectively cleaning be attached to the aggregate chips on the cutter head and be embedded in cobble between the cutter head, can when guaranteeing that cutter head is in optimum Working, improve the service life of cutter head.
