Background technology
Drawing and moving seat is the flexible connection structure between rear portion The middle pan of scraper conveyor and the hydraulic support, and an end is fixed on the ledge of intermediate channel, and the round-link chain that connects the hydraulic support oil cylinder is fixed in to draw and moves in the seat.As shown in Figure 1, the drawing of prior art moved seat 1 ' and is provided with positive right-angled crossing formula bar hole 2 ', and the point of crossing position is positioned at more than the vertical bar hole 22 ' center; As shown in Figure 2; The upright ring of round-link chain 4 ' peace ring 5 ' pass staggered form bar hole 2 ' get into draw move seat 1 ' after, round-link chain is vertically moved down along staggered form bar hole 2 ', make the flat ring 5 ' of round-link chain be stuck in to draw and move the seat the inside; Drawing slotting round pin 3 ' on the through hole that moves seat two walls again; Make round pin 3 ' be pressed in annulus chain link 5 ' above, block annulus chain link 5 ' and up turn over, just can't move the seat hauling-out as long as flat ring 5 ' is arranged in horizontal bar hole 21 ' below from drawing.This kind utilizes round pin will equal the fixed form that hoop presses down; Make draw move drawing of seat move a little highly too low, and common the drawing to move a little highly all to be higher than to draw and move drawing of seat and move a height, connection like this of hydraulic support oil cylinder; Form an inclination angle that makes progress; Draw the pulling force that makes progress in the coal process that intermediate channel is upwards waftd, form the groove that wafts, cause the coal weak effect.
The utility model content
The purpose of the utility model provides a kind of rear portion The middle pan of scraper conveyor and draws and move seat, overcomes upwards the waft problem of groove of intermediate channel.
The utility model rear portion The middle pan of scraper conveyor is drawn and is moved seat; Be suitable for affixed round-link chain; Said drawing moved seat and is fixedly connected on the ledge of intermediate channel, draws to move seat and comprise drawing and move seat body and blend stop, draws and moves the multiaspect cavity that seat body is an opening; The first chamber wall of said cavity is provided with and is suitable for the staggered form bar hole that round-link chain passes through; The staggered form bar hole is formed by horizontal bar hole and vertical bar hole intersection, and said horizontal bar hole is positioned at below the mid point of vertical bar hole with the point of crossing of vertical bar hole, is respectively equipped with corresponding first through hole on the second chamber wall of wall both sides, first chamber; Said blend stop passes first through hole, and the last plane of blend stop is higher than plane, place, horizontal bar hole coboundary in the vertical.
The utility model rear portion The middle pan of scraper conveyor is drawn and is moved seat, and wherein said blend stop is a cuboid, and said first through hole is a stepped hole, and the long limit that said stepped hole is suitable for the cuboid cross-sectional plane stands or minor face stands passes.
The utility model rear portion The middle pan of scraper conveyor is drawn and is moved seat, and the two ends of wherein said blend stop are provided with second through hole.
The utility model rear portion The middle pan of scraper conveyor is drawn and is moved the point of crossing that a difference from prior art is that the utility model is provided with horizontal bar hole and vertical bar hole and be positioned at below the mid point of vertical bar hole, and the last plane of blend stop is higher than plane, place, horizontal bar hole coboundary in the vertical, the upright ring of round-link chain is peaceful encircle pass the staggered form bar hole after; Round-link chain is vertically moved up along vertical bar hole; Plug blend stop again and pass two first through holes, lift on the flat hoop with round-link chain, and the last plane setting of blend stop is higher than plane, place, horizontal bar hole coboundary in the vertical; Blocking the annulus chain link prevents that it from moving down and gets back to horizontal bar hole; Round-link chain is fixed on to draw moves in the seat, this kind fixed form has improved to draw moves drawing of seat and moves a little, makes it be higher than drawing of hydraulic support oil cylinder and moves a little; Form downward pulling force; Intermediate channel is pricked downwards, the groove that wafts can not occur, help coal.
The utility model rear portion The middle pan of scraper conveyor is drawn and is moved in the seat, and it is a cuboid that blend stop is set, and cross-sectional plane has the different both sides of length; First through hole is a stepped hole, the long limit of cuboid cross-sectional plane is stood or minor face can both pass when standing, so; When long limit stands, the height that lifts on the flat hoop of round-link chain is higher, make to draw and move a little also carry higher; When minor face stood, the height that the annulus chain link is lifted was low slightly, and the drawing to move a little of raising also just hanged down slightly; Draw the difference of moving a little according to the hydraulic support oil cylinder, can move drawing to move a little and highly regulating of seat drawing; Be provided with second through hole at the two ends of blend stop, be suitable for passing spring cotter, prevent to draw to move past that blend stop moves from first through hole in the journey.
Below in conjunction with accompanying drawing to the rear portion The middle pan of scraper conveyor of the utility model draw move the seat be described further.

The specific embodiment
Like Fig. 3,4, shown in 5, the utility model rear portion The middle pan of scraper conveyor is drawn and is moved seat and comprise drawing and move seat body 1 and blend stop 2 that blend stop 2 is a cuboid.As can beappreciated from fig. 6; Draw and move the multiaspect cavity that seat body 1 is an opening; The first chamber wall 3 of cavity is provided with and is suitable for the staggered form bar hole 4 that round-link chain passes through; Staggered form bar hole 4 is formed by horizontal bar hole 41 and vertical bar hole 42 intersections, and laterally bar hole 41 is positioned at below the mid point of vertical bar hole 42 with the point of crossing of vertical bar hole 42.Being respectively equipped with corresponding first through hole, 6, the first through holes 6 on the second chamber wall 5 of the first chamber wall, 3 both sides is a stepped hole, and the long limit that is suitable for the cuboid cross-sectional plane stands or minor face stands passes.Blend stop 2 passes first through hole 6, and the last plane of blend stop 2 is higher than plane, place, horizontal bar hole 41 coboundaries in the vertical, and the two ends of blend stop 2 are provided with second through hole 7.
During installation; Move on the ledge that seat body 1 is welded to the rear portion The middle pan of scraper conveyor drawing, the upright ring peace ring of round-link chain is passed staggered form bar hole 4, again round-link chain is vertically moved up along vertical bar hole 42; Plug blend stop 2 again it is passed two first through holes 6; The last plane of blend stop 2 is higher than plane, horizontal bar hole 41 coboundaries places in the vertical, blocks the annulus chain link and prevents that it from moving down and get back to horizontal bar hole 41, makes round-link chain move the seat from drawing; In second through hole 7 at blend stop 2 two ends, insert spring cotter again, the other end of round-link chain connects the hydraulic support oil cylinder.
When the hydraulic support oil cylinder draw move a little lower the time, the minor face of blend stop 2 cross-sectional planes stood passes first through hole 6, draw this moment and move drawing of seat and move the low slightly of a raising.
Move a little higher the time when the hydraulic support oil cylinder draws, the long limit of blend stop 2 cross-sectional planes is stood pass first through hole 6, draw this moment and move drawing of seat and move the higher of a raising.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
