Description
Technical field
The present invention relates to a kind of mine hydraulic bracket more particularly to a kind of simple face end supports of offset.
Background technique
With the continuous development of fully-mechanized mining working mechanization, the raising of fully mechanized coal face coal production, it is desirable that the tunnel in exploiting field is disconnected
Face size is increasing, to meet ventilation, the requirement of transport.Therefore, tunnel would generally be equipped on the outside of working face open-off cut eye at present
Face end support is used to supported laneway top plate, avoids monomer column from supporting repeatedly and destroys back, and elapses forward speed
Fastly, labor intensity of workers is reduced, coal mine economic benefit is improved.But generally existing following problems of face end support at present:
1, when tunnel is relatively low, the face end support back pressure of head side needs biggish planted agent to measure to head；
2, pedestal uses chassis assembly, and elevating conveyor is placed on the bottom plate of face end support, has raised elevating conveyor, influenced to unload coal；
3, there is bastard coal to enter between face end support bottom plate and elevating conveyor, be not easy to be discharged, raised elevating conveyor；
4, the roadway deformation of gob side entry retaining is larger, and for reduction volume at 1 meter or more, traditional face end support is wider, can not promote；
5, traditional face end support increases planted agent and expands side amount, improves manual labor's intensity, it is hidden to increase safety
Suffer from.
Summary of the invention
The object of the present invention is to provide a kind of simple face end supports of offset.
The purpose of the present invention is what is be achieved through the following technical solutions:
The simple face end support of offset of the invention, face end support, which is located under elevating conveyor, helps side, the width of face end support pedestal
Degree is 700mm.
As seen from the above technical solution provided by the invention, the simple end branch of offset provided in an embodiment of the present invention
Frame, when being not in that tunnel is relatively low, the problem of set cap back pressure transporter head；It unloads coal no influence on coal unloading hole；Without examining
Consider and coal mining machine roller and transport head interference problem；And increase maintenance and pedestrian space；And when the tunnel of gob side entry retaining becomes
When shape is larger, position can be adjusted flexibly, adapt to tunnel situation.

Specific embodiment
The embodiment of the present invention will be described in further detail below.What is be not described in detail in the embodiment of the present invention is interior
Appearance belongs to the prior art well known to professional and technical personnel in the field.
The simple face end support of offset of the invention, preferable specific embodiment is:
Face end support, which is located under elevating conveyor, helps side, and the width of face end support pedestal is 700mm.
Face end support top beam fixes two root posts using one piece of column pressing plate simultaneously.
The design of face end support top beam has top to adjust jack, adjusts frame range≤350mm.
Face end support top beam is connected with a jack with the crab bearer top beam of working face the extreme side.
The caving shield of face end support has gear cash side retaining wall towards the design of the side of transfer conveyor tail.
Pedal is equipped with above the advancing jack of face end support.
Face end support can be applicable in left working face and right working face is used interchangeably.
The simple face end support of offset of the invention, solves the problems of the prior art, has the characteristics that following:
1, bracket, which is located under elevating conveyor, helps side, and when being not in that tunnel is relatively low, set cap back pressure transporter head is asked
Topic；
2, bracket, which is located under elevating conveyor, helps side, unloads coal no influence on coal unloading hole；
3, bracket, which is located under elevating conveyor, helps side, does not have to consider and coal mining machine roller and transport head interference problem；
4, when the roadway deformation of gob side entry retaining is larger, position can be adjusted flexibly, adapt to tunnel situation；
5, bracket base width only has 700mm, increases maintenance and pedestrian space；
6, frame jack is adjusted in top beam design, prevents bracket from wandering off and frame；
7, the stability of bracket is improved while increasing working resistance using one grade of double post design.
8, lighter in weight, operation is simple, different from the problem that conventional stent sebific duct is mostly random.
Specific embodiment:
