Abstract

The utility model relates to a double-beam double-column front hydraulic bracket stepping device, and belongs to the technical field of the underground supporting equipment in the coal mine. The hydraulic bracket stepping device comprises a plurality of groups of brackets which respectively consist of an external bracket door and an internal bracket door. The brackets are connected and fixed together. In the main technical proposal, two external bracket supporting columns of the external bracket door are sleeved outside two internal bracket supporting columns of the internal bracket door; an advancing bracket oil cylinder body is fixed at the upper beam of the external bracket; a piston rod end is fixed at the upper beam of the internal bracket; and the external bracket supporting columns and the internal bracket supporting columns form a supporting column oil cylinder. Because the utility model adopts the dual protection support of the external bracket door and the internal bracket door, the coal mining working surface can operate within the protection for production safety, and the external bracket door and the internal bracket door advance alternatively and can run synchronously with the coal winning machine, the front trough, the rear trough and the hydraulic bracket. The supporting top beam of the roadway can be repeatedly used; the resources can be saved; and the production cost is reduced.

Description

Twin-beam twin-column advanced hydraulic support step device
Technical field
The utility model belongs to support apparatus technical field under the coal mine.
Background technology
The support apparatus of existing conventional face has beams of metal individual prop and slippage bracket, and these two kinds of support apparatus all have characteristics in light weight, easy accessibility.But the beams of metal individual prop needs manually-operated when supporting, workman's working strength is big, and efficient is low, and support speed is slow and dangerous.
And slippage bracket is with slider guide mechanism the major-minor beam to be linked together, and when moving frame, the pillar reach is mentioned in a back timber step-down, and pillar is propped up; Another back timber step-down is carried post and is moved ahead then.Though use this class support to alleviate workman's part labour intensity, when moving frame, still need manually to set upright pillar, do not break away from heavy manual labor, and slippage bracket itself is unstable, can not guarantee the safety in production of work plane.
Summary of the invention
The purpose of this utility model provides a kind of twin-beam twin-column stepping leading hydraulic support, and is stable when moving frame, can alleviate workman's working strength, increases work efficiency.
The utility model is achieved in that twin-beam twin-column advanced hydraulic support step device, the structure of outrigger door is: vertical contractile outer post setting respectively is installed about on the outrigger bottom girder, outer post setting top is fixed on the outrigger upper beam, and outrigger is put the beams in place and is provided with the i iron guide rail; The structure of internal frame door is: interior post setting respectively is installed about on the internal frame bottom girder, and interior post setting top is fixed on the internal frame upper beam, and internal frame has roller on putting the beams in place, and roller is positioned at internal frame upper beam lateral surface;
Two outer post settings of outrigger door are sleeved on two interior post setting outsides of internal frame door, and the cylinder body that moves the frame oil cylinder is fixed on the outrigger upper beam, and piston rod end is fixed on the internal frame upper beam; Outer post setting, interior post setting are the pillar oil cylinder; Hydraulic jack links to each other with oil pump station by pipeline road, and is provided with the operation valve on each pipeline.
Compared with prior art the beneficial effects of the utility model are: owing to adopted the duplicate protection of outrigger door and internal frame door to support; coal-face can be in the protection work down of production safety; outrigger door and internal frame door alternately move ahead, and can walk in the same way synchronously with coal-winning machine, front and back chute, hydraulic support.The supporting back timber in tunnel can recycle, and economizes on resources, and has reduced cost of production.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the B-B sectional view of Fig. 1.
The specific embodiment
Be described further below in conjunction with accompanying drawing.
The structure of outrigger door 1 is: vertical contractile outer post setting 6 respectively is installed about on the outrigger bottom girder 8, and outer post setting 6 tops are fixed on the outrigger upper beam 11, and outrigger upper beam 11 is provided with i iron guide rail 5;
The structure of internal frame door 3 is: post setting 7 in respectively being equipped with about on the internal frame bottom girder 9, interior post setting 7 tops are fixed on internal frame and put the beams in place on 10, and roller 4 is positioned at internal frame 10 lateral surfaces of putting the beams in place;
Two outer post settings 6 of outrigger door 1 are sleeved on two interior post setting 7 outsides of internal frame door 3, and the cylinder body that moves frame oil cylinder 2 is fixed on the outrigger upper beam 11, and piston rod end is fixed on the internal frame upper beam 10; Outer post setting 6, interior post setting 7 are the pillar oil cylinder.
As shown in Figure 1, roller 4 is installed in internal frame 10 lateral surfaces of putting the beams in place.Roller 4 stretches with internal frame column 7, outrigger column 6 and moves up and down at outrigger 11 medial surfaces of putting the beams in place.The structure of roller 4 is identical with the roller structure of the matching used sliding seat of existing i beam guide rail.
When internal frame 10 ends of putting the beams in place withstand on the tunnel and push up, when internal frame bottom girder 9 contacts with ground, outrigger column 6 shrinks, descend, outrigger upper beam 11 leaves on the tunnel and pushes up outrigger bottom girder 8 built on stilts, at this moment roller 4 is positioned at the put the beams in place soffit on 11 medial surface tops of outrigger, this time shift frame oil cylinder 2 shrinks, and roller 4 is put the beams in place along outrigger and 11 moved, and has finished outrigger door 1 and has moved and move a step.
Afterwards, internal frame door 1 begins reach.
Stretch on the outrigger column 6, outrigger bottom girder 8 contacts with ground, and outrigger 11 tops of putting the beams in place are withstood on the tunnel and pushed up.
At first internal frame column 7 shrinks, and descends, and internal frame upper beam 10 leaves on the tunnel and pushes up, internal frame bottom girder 9 built on stilts, and at this moment roller 4 is positioned at the outrigger upper beam 11 inboard basifacial planes of going up.Stretch out with time shift frame oil cylinder 3 piston rods, promote internal frame door 3 and move forward a step.
Afterwards, internal frame bottom girder 9 contacts with ground, and internal frame 10 tops of putting the beams in place are withstood on the tunnel and pushed up.
Circulate repeatedly with this, internal frame door 3, outrigger door 1 take turns to walk forward, guarantee to have all the time a pack support to support and withstand the top, tunnel.
Outer post setting 8, interior post setting 7 are the pillar oil cylinder.Identical with existing mine prop cylinder structure.Outer post setting pool cylinder cylinder body is fixed on the outrigger bottom girder 8, and piston rod end is fixed on the outrigger upper beam 11.Interior post setting 7 cylinder blocks are fixed on the internal frame bottom girder 9, and piston rod end is fixed on the internal frame upper beam 10.
