Abstract
The utility model provides a pass connecting block for circulating from moving advance support hydraulic support, be fixed with on a supporting beam assembly winding and unwinding devices's drive chain pass the connecting block, this pass connecting block includes bottom plate and clamp plate, the drive chain is located between the clamp plate and the bottom plate of passing the connecting block, the side is equipped with two at least arc pits on the bottom plate both ends, the cambered surface axis of these two pits is along bottom plate length direction, distance between two adjacent pit centers equals with the pitch of drive chain, correspondingly also be equipped with the arc pit in clamp plate downside corresponding position. The utility model discloses in set up arc pit structure and drive chain and cooperate, accessible drive chain drives and rotates with drive chain matched with sprocket, drives the motion that a supporting beam subassembly winding and unwinding devices who locates track subassembly front end and rear end realized receiving and releasing supporting beam subassembly, adopts the utility model discloses a to the strut of tunnel roof when the advance support not only can play the coal mining, can also realize moving the effect of frame, crane automatically, it is fast to move the frame.
Description
Technical field
The utility model relates to comprehensive mechanical coal mining roadway support equipment under the coal mine, specifically is a kind of passing contiguous block that is used to circulate from moving forepoling hydraulic support.
Background technology
Rich coal resources in China, fully-mechanized mining equipment is ripe, and coal winning technology is gradually improved; In short supply along with the energy, the quickening day by day of coal in China exploitation paces is also had higher requirement to the moving of support in tunnel like this; Such as requiring support can move frame automatically,, effective support is carried out in the tunnel to accelerate advancing velocity; Supporting measure before adopting can not adapt to the speed of present exploitation, and security performance is unstable.The applicant is in practical new patent " automatic moving type crossheading advance support rack " (on 07 13rd, 2009 applying date of the China of application in 2009; At on 05 12nd, 2010 notice of authorization day; Notice of authorization CN 201460937U); This support frame can realize moving automatically frame, but it adopts the step type moving manner, and the advancing velocity of this support is also lower.
Summary of the invention
The purpose of the utility model is to provide a kind of passing contiguous block that is used to circulate from moving forepoling hydraulic support; Describedly thisly be used for circulating that will to solve prior art tunnel support frame advancing velocity from the passing contiguous block that moves forepoling hydraulic support slower, can not satisfy the technical problem of the requirement that coal mining speed improves.
The purpose of the utility model realizes through following technical scheme: this circulation is from moving chain and sprocket driving device and the brace summer assembly draw off gear that is provided with rail assembly, brace summer assembly in the forepoling hydraulic support, moves the brace summer assembly; Be equipped with brace summer assembly draw off gear in the front-end and back-end of rail assembly; It is characterized in that: on the drive chain of brace summer assembly draw off gear, be fixed with described passing contiguous block; This passing contiguous block comprises base plate and pressing plate; Pressing plate is located on the base plate by bolt, and chain drive-belt is located between the pressing plate and base plate of passing contiguous block, and the base plate downside is provided with the connection otic placode; Base plate two ends upper side is provided with at least two arc pits; The cambered surface axis of these two pits is along the floor length direction, and the distance between adjacent two arc pit centres equates with the pitch of drive chain, correspondingly also is provided with the arc pit at pressing plate downside correspondence position.
Base plate two ends upper side is provided with four arc pits, correspondingly, also is provided with four arc pits at the pressing plate downside, and wherein the width of two the arc pits in middle part equates, the width of two arc pits is the half the of middle part arc pit on the limit.
Between base plate and pressing plate, also be provided with backing plate, backing plate is between the arc pit at base plate upper side two ends.
The utility model is compared with prior art, and its effect is actively with tangible.Originally be used for circulating and from the passing contiguous block that moves forepoling hydraulic support the arc bowl configurations be set and match with chain drive-belt; Can chain drive-belt be clipped in through bolt like this and pass on the framework; Driving the passing contiguous block by a passing jack moves; And then through the sprocket rotation that the chain drive-belt drive matches with chain drive-belt, drive the motion that the brace summer assembly draw off gear of being located at the rail assembly front-end and back-end is realized folding and unfolding brace summer assembly, so that automatically last group brace summer assembly frame is fallen on track; The brace summer assembly that will move to the track front end is then transferred to normal supporting state; To the supporting of back, can also realize moving automatically the effect of frame, crane when the advance support rack of employing the utility model not only can play coal mining, advancing velocity is fast.

Fig. 2 is the lateral view of Fig. 1.
Fig. 3 is the Q-Q sectional view of Fig. 2.
The specific embodiment
Through embodiment the utility model is done further explain below in conjunction with accompanying drawing.
Like Fig. 1, Fig. 2 and shown in Figure 3.In the present embodiment; This circulation is from moving chain and sprocket driving device and the brace summer assembly draw off gear that is provided with rail assembly, brace summer assembly in the forepoling hydraulic support, moves the brace summer assembly; Be equipped with brace summer assembly draw off gear in the front-end and back-end of rail assembly; It is characterized in that: on the drive chain of brace summer assembly draw off gear, be fixed with described passing contiguous block, this passing contiguous block comprises base plate 671 and pressing plate 672, and pressing plate 672 is located on the base plate 671 by bolt; Chain drive-belt is located between the pressing plate 672 and base plate 671 of passing contiguous block; The base plate downside is welded with and connects otic placode 673, and base plate two ends upper side is provided with four arc pits 674, and the cambered surface axis of these four pits 674 is along base plate 671 length directions; Distance between adjacent two arc pit centres equates with the pitch of drive chain, correspondingly also is provided with arc pit 675 at pressing plate 672 downside correspondence positions.Wherein the width of two the arc pits in middle part equates, the width of two arc pits is the half the of middle part arc pit on the limit.
Between base plate and pressing plate, also be provided with backing plate 676, backing plate can be used for being adapted to the chain clamping of differing heights through backing plate between the arc pit at base plate upper side two ends.
Certainly, the quantity of arc pit is at least two clampings that just can realize chain on base plate and the pressing plate, and its concrete quantity can be adjusted according to the active force to chain.
