Description
Technical field
The utility model belongs to the coal mine machinery equipment field, specially refers to a kind of puppet bow oblique coal face hydraulic support and scratch board conveyor coupling arrangement.
Background technology
At present, the half-edge coal seam fully-mechanized mining working all is to arrange along the true dip direction in coal seam both at home and abroad.But, when seam inclination is soft greater than 50 ° and coal seam, gliding and coal wall caving occurs appears in existing fully-mechanized mining equipment easily, fully-mechanized mining working equipment is in case occur gliding, because seam inclination is large, the fully-mechanized mining equipment that has glided to be returned to the normal position, very time-consuming, and can affects safety production and production efficiency.Fully-mechanized mining working equipment glides and the coal wall caving problem in order to solve, and fully-mechanized mining working is arranged by the true dip direction change into along the puppet tilted direction layout of bowing, and just is equivalent to reduce seam inclination, is conducive to the stability of raising equipment and rib.But the connector on original comprehensive mining hydraulic bracket push rod is that cross-drilled hole is connected with vertical connection ear on the scratch board conveyor, the direction of connector is all the time perpendicular to scratch board conveyor, thereby connector can't be along the direction move left and right of scratch board conveyor laying, so this kind draw bail, can only adapt to along the true dip direction and arrange fully-mechanized mining working, bow after the slanting face because make puppet into when coal-face, the position relationship of hydraulic support and scratch board conveyor no longer is vertical relation, support is in the process of passing scratch board conveyor, cause easily connector, connect the phenomenon that ear is fractureed, therefore, the connected mode of original connector and scratch board conveyor is not suitable for the puppet oblique coal work exploitation of bowing and uses.Therefore, design and a kind ofly can be applicable to the bow coupling arrangement of slanting face hydraulic support and scratch board conveyor of puppet, it is not fragile to guarantee that coupling arrangement uses in puppet is bowed the slanting face, is the bow key factor of oblique fully-mechanized mining working exploitation success of puppet.
Summary of the invention
The purpose of this utility model is: overcome the deficiency that prior art exists, a kind of puppet bow oblique coal face hydraulic support and scratch board conveyor coupling arrangement are provided, satisfy hydraulic support and can be coupled to each other with scratch board conveyor in the puppet slanting face of bowing, and solve connector of hydraulic support and scratch board conveyor connects the problem that ear fractures easily.
The technical solution of the utility model is achieved in that a kind of puppet bow oblique coal face hydraulic support and scratch board conveyor coupling arrangement, mainly comprise the support push rod, connector, vertical core, cross-drilled hole, first line of a couplet lug, second line of a couplet lug, upper earhole, lower earhole, perpendicular pin, lateral pin, base, ledge, plate in the scratch board conveyor, scratch board conveyor, first line of a couplet lug, second line of a couplet lug is parallel to plate in the scratch board conveyor, and be welded on the ledge side, connector is placed on first line of a couplet lug, in the middle of the first line of a couplet lug, perpendicular pin passes the upper earhole of first line of a couplet lug, the vertical core of connector, the lower earhole of second line of a couplet lug, with the vertical core connected mode, connector is connected in first line of a couplet lug, between the second line of a couplet lug, connector can be around perpendicular pin at first line of a couplet lug, left-right rotation is 0 ° between the second line of a couplet lug--and 180 °, connector cross-drilled hole end inserts in the support push rod, lateral pin passes the cross-drilled hole of support push rod and connector, with the cross-drilled hole connected mode, connector is hinged on the support push rod, and connector can swing up and down in the support push rod around lateral pin.
A kind of puppet that the utility model provides bow oblique coal face hydraulic support and scratch board conveyor coupling arrangement, when puppet is bowed oblique coal-face use, coupling head is sold at first line of a couplet lug around perpendicular, left-right rotation between the second line of a couplet lug, can carry out 0 ° with scratch board conveyor--180 ° of angles connect, satisfy hydraulic support and the puppet slanting face of bowing and become 0 °--during 180 ° angle, be rotatably connected in the connector on the scratch board conveyor, find the support push rod to connect with the support push rod with the angle position of scratch board conveyor, realize that hydraulic support and scratch board conveyor link, hydraulic support is with after scratch board conveyor connects, pass through hydraulic support push rod, the action of column reaches scratch board conveyor and hydraulic support to the puppet purpose that oblique stope rib advances of bowing.
The beneficial effects of the utility model are: the coupling arrangement that has solved original hydraulic support and scratch board conveyor can't satisfy the puppet technical barrier that oblique fully-mechanized mining working uses of bowing, this utility model is simple in structure, use reliably, overcome the defective that original connection ear and connector are easily fractureed.
