Description
Technical field
The present invention relates to mining machinery field, in particular to a kind of adaptive top beam of advanced hydraulic support is adapted to coal mine
It is uneven or have certain tilt angle back supporting.
Background technique
Underground mine back complicated condition, general tunnel is moved towards along working face and working face tendency direction has centainly
Inclination angle, the top beam of advance timbering is designed as overall structure more at present, and the contact of top beam and back is poor, imitates to roof timbering
Fruit is undesirable, and top beam is easy to appear structural member damage phenomenon due to unbalance stress.Therefore it is required that top beam vertical and horizontal all
There is certain angle of oscillation, to adapt to top beam changing capability.
Patent of invention (ZL 201410091739.8) discloses a kind of adaptive leveling method of hydraulic support top beam and dress
It sets, this method is the numerical value of real-time monitoring obliquity sensor and result to be fed back to the master of system during hydraulic support setting prop
Controller, master controller are adjusted in real time according to top beam inclination angle, and it is very heavy that adjustment balance is begun through when column reaches just support
Top is to control top beam state.This method has two: (1) adaptation range is limited: being mainly adapted to the two of balance jack
Column protected type hydraulic support then can not for four post support shield type bracket or without the hydraulic support of balance jack structure
Control top beam state；(2) adaptability is not strong: top beam is mainly adjusted to horizontality by this method, when top plate is uneven or has
Certain tilt angle, then top beam and top plate are unable to close contact, and ideal supporting state is not achieved in hydraulic support.
Summary of the invention
The purpose of the present invention is for coal mine down-hole tunnel advance timbering provide it is a kind of can vertical and horizontal swing
Top beam allows advance timbering top beam to have and adapts to uneven or have certain tilt angle back supporting, improves advance timbering
Adaptability.
Technical solution: two limit plates are arranged in the bolumn cap longitudinal direction of traditional advance timbering top beam in the present invention, work as top beam
When pivot angle is more than design pivot angle α before and after longitudinal direction, limit plate contacts limit with the column cap of column, allow top beam longitudinal oscillation angle not
More than design pivot angle α.
Capital hole on hydraulic support column uses taper symmetrical structure, and capital sells both ends and uses spindle-type α-Fe2O3, pin shaft
Capital pin is fixed on the fixation otic placode of bolumn cap with briquetting, it is fixed when top beam or so lateral deflection angle is more than design pivot angle β
Otic placode contacts limit with the column cap of column, allows top beam horizontal swing angle to be no more than design pivot angle β, top beam is in entire swing process
In, capital pin is unfettered, pin stress bending in capital when top beam being avoided to swing.
The invention patent solves advance timbering top beam and adapts to uneven or have certain tilt angle back supporting
Problem allows advance timbering top beam all to have a fixed pendulum in vertical and horizontal both direction by the limiting device of top beam and column
Kinetic force improves advance timbering adaptability, preferably maintenance back.
Present invention tool has the advantage that.
(1) package unit is mainly made of fixed otic placode, limit plate, capital pin, briquetting and pin shaft, and structure is simple.
(2) pin both ends in capital are designed as special spindle-type α-Fe2O3, and top beam during horizontal swing, freely transport by capital pin
It is dynamic, it does not constrain, pin stress bending in capital when top beam being avoided to swing.
