Abstract
The invention discloses integrally-moving protective forepoling for coal mine stope faces, which can serve as a protective forepoling, an end support and a transitional support. The integrally-moving protective forepoling is a hydraulic support which moves forward by the aid of an integral push device and is applicable to different stoping methods, different stoping heights and different roadway widths of coal mine stope faces.
Description
Technical field
The present invention relates to a kind of stope working surface of coal mines termination, lead-over groove, crossheading advanced stand device.
Background technology
At present, stope termination, lead-over groove, crossheading advanced stand device that the colliery is used are that hydraulic prop is joined hinged girder or ∏ type beam mostly, and support capacity is little, and dismounting, installation all need manually-operated, and labour intensity is big, poor stability.The special hydraulic support supporting is used in indivedual collieries, and support capacity is strong, and weight is big, transportation, install, move, maintenance difficulty is big.
Summary of the invention
The technical problem that the present invention will solve provides a kind of integral movable type advance support rack; Can be used as face end support and transition bracket simultaneously uses; The integral movable type advance support rack is a kind of self-advancing hydraulic support that utilizes push unit to realize; What of back timber can carry out reasonable disposition according to drift section and pressure condition, and the working resistance of pillar and bearing height can be selected according to actual conditions; Push unit is made up of brace summer and hydraulic pressure passing jack, and the length of brace summer is determined by span length.
Description of drawings
Fig. 1 is an integral movable type advance support rack structural representation of the present invention.
Fig. 2 is an integral movable type end support supporting structure sketch map of the present invention.
Fig. 3 is an integral movable type transition support frame structural representation of the present invention.
The specific embodiment
The technical scheme that the integral movable type advance support rack is taked is: mention the hydraulic prop (4) under the inboard back timber, utilize support back support beam (2) to do fulcrum, pass jack (3) and pass front support beam (2); Front support beam (2) drives inboard back timber (1) reach, after mobile the completion, hydraulic prop is propped up; Mention the hydraulic prop (4) under the back timber of the outside, utilize support front support beam (2) to do fulcrum, pass jack (3) and draw back support beam (2); Back support beam (2) drives outside back timber (1) reach; After moving completion, again hydraulic prop is propped up, accomplish one and move circulation.
Claims (4)
1. integral movable type advance support rack; Comprise back timber (1), brace summer (2), hydraulic pressure passing jack (3), bidirectional hydraulic pillar (4); It is characterized in that: back timber (1) and brace summer (2) are hinged or be slidingly connected; Pass jack (3) through hydraulic pressure between two brace summers (2) and connect, four above bidirectional hydraulic pillars (4) respectively with vertical connection of back timber (1).
2. according to the said integral movable type advance support rack of claim 1, it is characterized in that: back timber (1) and brace summer (2) are hinged or be slidingly connected
3. according to the said integral movable type advance support rack of claim 1, it is characterized in that: pass jack (3) through hydraulic pressure between two brace summers (2) and connect,
4. according to the said integral movable type advance support rack of claim 1, it is characterized in that: four above bidirectional hydraulic pillars (4) respectively with vertical connection of back timber (1).
