Abstract

A lane fore supporting frame is provided. Two frames parallelly form a group and realize connection by the use of a falling resistance jack via a connection lug; every frame consists of support beams, upright posts, a base, a four connection pole mechanism, and also a shed replacing mechanism and a moving frame jack hinged at the front of the support beam, and a retractable beam is further provided. Wherein, one end of the support beam is connected with the shed replacing mechanism via the hinge pin, and the other end of the support beam is connected with one end of the retractable beam via the hinge pin, while the other end of the retractable end is hinged with the support beam of the other support frame; every support beam realizes connection with base via two upright posts and the four connection pole mechanism between two upright posts; and the moving jack connects two neighboring bases. This kind of supporting frame realizes self advancing support in the mine lane, thereby ensuring safety of the underground minors and devices in the lanes. The utility model belongs to mine mechanism manufacture and application fields.

Description

Lame advanced supporting rack
Technical field: the utility model relates to a kind of lame advanced supporting rack, and this kind support can carry out in various mine laneways from moving the stepped type supporting, the safety of equipment in protection underground labour and the tunnel.Belong to mining machinery manufacturing and application.
Background technology: in the mine of modern fully-mechanized mining, especially in the stope of coal mines, along with the propelling of coal-face, the tunnel at work plane two ends is destroyed thereupon, the tunnel at the rear that coal-face moves collapses and, and it is unstable that near the tunnel the work plane also becomes; Yet be again the only way which must be passed that production equipment is assembled transportations such as ground and coal and equipment in the tunnel, work plane two ends, therefore national Safety of Coal Mine Production rules stipulate that clearly work plane two lanes add the strong supporting section must not be less than 20 meters.But at present China's coal-mine is very few to herein " adding strong supporting " way, and not only efficient is low, the time and influence the propelling of high-yield and high-efficiency work plane, even because supporting relies on manpower fully and the generation of security incident is arranged repeatly in advancing.
Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, and provides a kind of scientific structure reliable and meet the lame advanced supporting rack that condition is installed and used in the down-hole.This lame advanced supporting rack is formed one group side by side, is connected by engaging lug by anti-down jack between two for two; Every comprises back timber, column, base and quadric chain, and be articulated in the back timber front end the roof replacing machine structure, move the frame jack, it also comprises extensible canopy, one end of above-mentioned back timber links to each other with the roof replacing machine structure by bearing pin, the other end links to each other with an end of extensible canopy by bearing pin, and the other end of extensible canopy and the back timber of another support are hinged; Link to each other with quadric chain in the middle of being positioned at two root posts by two root posts between each back timber and the base; Be connected with between two adjacent bases and move the frame jack.
Described extensible canopy is made of the inside and outside casing of socket, and inside and outside casing is connected with adjacent two back timber by bearing pin respectively; Inside and outside casing is welded with the ear seat with the back timber junction separately close, and connects by jack.
The utlity model has following characteristics:
1, all connections are simple bearing pin connection, adapt to the down-hole and install and use condition;
2, support is that unit uses with the group, and a pack support is formed side by side by two, and two supports support each other, alternately walking;
3, connect with anti-down jack between two, not only can adjust spacing, the attitude of two supports, also do not influence it and alternately move ahead;
4, every support width is narrower, and it is few to take lane space, and haulage device is arranged between two, and two supports outside can the pedestrian, has protected equipment and workman's safety;
5, the stent support ability is big, and working resistance is big, and reasonable to tunnel top, base plate active area, the supporting state is good;
6, each jack of support is controlled by hydraulically operated valve, and operation control is flexible, and the cancellation a dead lift can be realized advancing synchronously with work plane, boosts productivity greatly.
Description of drawings:
Fig. 1 is a front view of the present utility model, and dotted portion is one of connected back.
Fig. 2 is a lateral view of the present utility model.
Fig. 3 is a base vertical view of the present utility model.
The specific embodiment:
Embodiment:
With reference to Fig. 1-3, two of this lame advanced supporting racks are formed one group side by side, are connected by engaging lug 7 by anti-down jack 8 between two; Every comprises back timber 1, column 2, base 3 and quadric chain 4, and be articulated in back timber 1 front end roof replacing machine structure 1-1, move frame jack 6, it is characterized in that: it also comprises extensible canopy 5, one end of above-mentioned back timber 1 links to each other with roof replacing machine structure 1-1 by bearing pin, the other end links to each other with an end of extensible canopy 5 by bearing pin, and the other end of extensible canopy 5 and the back timber of another support 1 are hinged; Link to each other with quadric chain 4 in the middle of being positioned at two root posts 2 by two root posts 2 between each back timber 1 and the base 3; Be connected with between two adjacent bases 3 and move frame jack 6.
Described extensible canopy 5 is made of the inside and outside casing of socket, and inside and outside casing is connected with adjacent two back timber 1 by bearing pin respectively; Inside and outside casing is welded with the ear seat with back timber 1 junction separately close, and connects by jack 5-1.
Operating principle of the present utility model:
During holding state, as shown in Figure 1, column stretches out, and back timber 1 and base 3 support top, the base plate in tunnel respectively; When dividing a word with a hyphen at the end of a line away, frame falls in one group of the front one (among Fig. 1 one of solid line), be that column 2 is regained, this moment, jack 5-1 and anti-down jack 8 were in the servo-actuated state, after back timber 1 leaves top board, and jack 5-1 and move frame jack 6 and stretch out, (among Fig. 1 one of dotted line) is in holding state because the support of back, this of front will be passed a jack stroke forward, and its column 2 rises then, and support is in holding state; At this moment the support of back (among Fig. 1 one of dotted line) column 2 reduces, and back timber 1 leaves top board, jack 5-1 and move 6 withdrawals of frame jack then, and then the support of back has been dragged a stroke forward; Column 2 rises, and support is in holding state again; In like manner, another arranged side by side with it passed a stroke forward with same process, and after the support, one of the back also and then moves forward a stroke.
