Description
Technical field
The utility model is related to Suporting structure technical fields, more particularly to a kind of list with offset monitoring function
Sword hobboing cutter.
Background technology
Growing with city, traffic problems also gradually highlight, and subway is the effective ways for alleviating traffic congestion.
After each Development of large city to certain phase, subway will certainly be all built on a large scale.And during subway work, Suporting structure is
Its essential digging tool.The large shield device structure of the prior art is complicated, involves great expense.Due in shield driving
Cheng Zhong needs to use hobboing cutter component to break ground, and the hobboing cutter component of shield machine is wear-out part, and service life is generally dependent on
The geological conditions of soil property.Common single-blade hob is usually all that heavy cutter ring is utilized to be installed with cutter hub interference fit, between existing centainly
Gap, and in use, heavy cutter ring due to unbalance stress is easy that larger offset or rotation occurs with cutter hub, leads to knife
Abrasion deformation occurs for external diameter, this is the main reason for causing cutter hub to fail, but since mechanicalness noise is big, the offset of heavy cutter ring
It is generally difficult to discover, so frequently resulting in cutter hub failure, needs to frequently replace, influence construction speed, increase construction cost.
Utility model content
The purpose of this utility model is that：It is easy to solve common single-blade hob because heavy cutter ring and cutter hub generation are inclined
It moves, causes cutter hub outer diameter that abrasion deformation occurs, reduce single-blade hob service life, influence construction speed, increase construction cost
Problem, the utility model provide a kind of single-blade hob with offset monitoring function.
The utility model specifically uses following technical scheme to achieve the goals above：
A kind of single-blade hob with offset monitoring function, including cutter shaft, outer cover plate, bearing, Seal Kit, cutter hub, again
Type cutter ring and mechanism for monitoring for monitoring heavy cutter ring offset, the outer cover plate are connected to the upper end of cutter shaft, the knife
Body is mounted on by bearing on outer cover plate, and the gap setting that the cutter hub is contacted with outer cover plate has Seal Kit, the heavy type knife
Mounted on the upside of cutter hub, the mechanism for monitoring is arranged on the outer ring of cutter hub with heavy cutter ring interference installation place circle；
The mechanism for monitoring includes flexible protective cover body, limiting plate, adjustable spring, pressure sensor, alarm, described soft
Property protecting cover one end be fixed on cutter hub, the other end of flexible boot is contacted by rubber pad with heavy cutter ring, described
Limiting plate is connect by adjustable spring with pressure sensor, and the pressure sensor is connected to by circuit with alarm, the pressure
Force snesor and alarm are each attached on cutter hub.
Preferably, the surface of the heavy type cutter ring is provided with one layer of coarse friction and breaks ground layer.
Preferably, being additionally provided with the abrasion detection ring for prompting changing in the middle part of the heavy type cutter ring.
The beneficial effects of the utility model are as follows：
1. common single-blade hob is installed using heavy cutter ring and cutter hub interference fit, there are certain intervals, and
In use, heavy cutter ring is easy that larger offset or rotation occurs with cutter hub, is led to cutter hub outer diameter due to unbalance stress
Abrasion deformation occurs, this is the main reason for causing cutter hub to fail.In operation process, since mechanicalness noise is big, and tunneling
The offset of the total heavy cutter rings of process Huang is difficult to discover, so frequently resulting in cutter hub failure, needs to frequently replace, influence to construct into
Degree increases construction cost.For this problem, the present apparatus is provided with mechanism for monitoring on the outside of heavy cutter ring, can find weight in time
Whether offset by a relatively large margin is occurred between type cutter ring and cutter hub, once there is the offset beyond normal range value, testing agency
Just can automatic alarm, remind operator single-blade hob is adjusted, can deviation occur first time correct in time, avoid
It is chronically at deviation post, and generation is irreversible to be seriously worn, to play the work of the heavy cutter ring offset distance of automatic monitoring
With improving the service life of single-blade hob, ensured construction speed, saved consumables cost.
2. traditional single-blade hob is directly broken ground by cutter head, since cutter head is mostly metal material, cutter head is using one
It after the section time, is easy to be polished smooth, reduces with the frictional force of soil, skid so as to cause cutter head, influence is broken ground efficiency, sternly
Ghost image rings construction speed, causes the consumption in vain of the energy.For this problem, the present apparatus is provided with one on the surface of heavy cutter ring
The coarse friction of layer is broken ground layer, be can effectively prevent heavy cutter ring ontology and is worn, using friction break ground layer offer frictional force come
It breaks ground, can effectively prevent heavy cutter ring and skid, substantially increase efficiency of breaking ground, saved the energy.
3. heavy cutter ring is in use, inevitably there is loss, the method that tradition checks the need for replacing hobboing cutter is
By way of naked eyes identification or by measurement, this mode inefficiency, and can not find in time in actual use
Hobboing cutter has exceeded effective use scope, and being continuing with can cause driving progress to slow down, hobboing cutter idle running, in vain consuming energy etc. one
Series of problems.For this phenomenon, the present apparatus effectively uses the tail position at end in heavy cutter ring, provided with one section for reminding
The abrasion detection ring of replacement, since abrasion detection ring is different from heavy cutter ring material, was breaking ground after may wear to this position
Cheng Zhonghui sends out the sound different from heavy cutter ring and soil block friction, to intuitively judge whether to have reached effective critical model very much
It enclosing, the person of being conveniently operated shuts down replacement in time, avoids the energy consumption that invalid free-running belt is come, improves the service efficiency of hobboing cutter,
Construction speed is ensured.
