Abstract
The present invention relates to a hydraulic support for underground extracting working faces for coal mines, which is composed of top beams, a thrust oil cylinder, an individual hydraulic strut and two sets of flexible four bar linkage mechanisms, wherein one side of one set of the flexible four bar linkage mechanisms is provided with an upright swing bar with two arched slotted holes; the upright swing bar forms an upright swing sliding block bar linkage mechanism together with a sliding block, an upper link bar, a pin shaft and a positioning plate. When the support travels, one top beam supports a top plate, and the other top beam changes the distance from the back end to the supporting top beam through the swing of the upright swing bar so as to achieve the purpose of the automatic regulation of support moving direction. The present invention has the advantages of labor saving of moving the support, convenient operation, high flexibility and strong adaptive capacity.
Description
The present invention relates to the hydraulic support that stope is used under a kind of coal mine, be specially adapted to breaking roof and inclined seam stope.
Existing hydraulic prop for moving suspended top beam (China's patent 88104291) is made up of two support bodys, and each support body all has back timber, hydraulic prop etc.Two back timbers of hydraulic support are linked together by two groups of flexible quadric chains and slideway; Being hinged on the propelling oil cylinder of a back timber and the connecting rod hinge that waves on another back timber is hinged and realizes moving frame; But a back timber tilts with respect to another back timber front, rear, left and right, not only can be used for gently inclined seam, also can be used for high inclination-angle and breaking roof coal seam.But this hydraulic support is in moving frame, when needing to adjust direction of advance, because top board, especially loose roof, presses down with the back timber of off-load, is difficult to tuning, therefore, lean on artificial pulling back timber just can finish.
The object of the present invention is to provide a kind of support apparatus not enough in the prior art that overcomes.It not only can realize that half off-load moves frame by the linkage of back timber, adapts to different top board conditions, and can move the frame direction by automatic adjusting of upright fork swing of linkage, thereby reach wide adaptability, safe and reliable purpose as required.
The technical measures that the present invention taked are steering hydraulic support by back timber, propelling oil cylinder, hydraulic prop, and two group four connects mechanism's composition; Wherein a side of one group of quadric chain is provided with the upright fork with two long arc-shaped holes, and and slide block, goes up connecting rod, bearing pin and location-plate and form upright pendulum sliding-block linkage.
The technical measures that the present invention taked are that also steering hydraulic support Zuo Liang right side is welded with two location-plates in front and back, and there is the pin-and-hole of wearing bearing pin location-plate lower end, front and back, and there is the long arc-shaped holes of supply and marketing axle swing at upper end and middle part.
The technical measures that the present invention taked are that also upright fork has three pin-and-holes in upper, middle and lower, and following hole is connected with the location-plate lower end by bearing pin, and mesopore is worn bearing pin, and last hole is by bearing pin and last connecting rod and location-plate upper articulation.
The present invention compares with existing support apparatus, has following technique effect:
1, every pack support is formed by two support bodys, forms twin beams and supports side by side, can realize that half uninstall moves frame.Simultaneously, owing to adopted upright pendulum sliding-block linkage, therefore, can make support in advancing, a back timber roof supporting, another back timber changes the spacing of its rear end and supporting top beam by upright fork swing, thereby reach the purpose of adjusting the support direction of advance, and it is laborsaving to move frame, easy to operate, flexible, adaptive capacity is stronger.
2, because two back timbers of every pack support are hinged by one group of flexible quadric chain and one group of upright pendulum sliding-block linkage, the linkage of forming parallel four limit row, along with the variation of the linkage of parallelogram, a back timber can be higher or lower than another back timber of support arranged side by side like this.When support does not stress, the last plane keeping parallelism of two back timbers, when top board not at ordinary times, distance between the bearing pin of quadric chain can change, and to adapt to the top board injustice, four top shoes that connect mechanism also can turn an angle in the direction of back timber slideway upper edge beam simultaneously, high back is low before promptly allowing to occur a back timber, and the duty at the high preceding end behind another back timber, therefore, support can adapt to the rough variation of top board all directions.
3, the flexible connecting rod of support is made with spring steel, thereby the excursion of its adaptation is big, and stress is good, and job safety is reliable.
4, two of this support back timbers and hydraulic prop are dismantled easily, and each component weight is light, convenient in carrying, and the low cost of manufacture of support only is about 1/10th of a general hydraulic support.
Description of drawings is as follows:
Fig. 1, back four connecting rod slider adjusted device front views.Right back timber 1, left back timber 2, upright fork 3, rear slider 4, bearing pin 5 are wherein arranged, go up connecting rod 6, connecting rod coupling pin 7, alignment pin 8, bearing pin 9.
Fig. 2, back four connecting rod slider adjusted device lateral views.Location-plate 10, gusset 11, cottor pin 12, liner 13 are wherein arranged.
Fig. 3, back four connecting rod slider adjusted device A-A sectional drawings.Steel wire 14, spacer pin 15 are wherein arranged.
Embodiments of the invention are to pass through the two groups of quadric chains in front and back by back timber and the support body that advances oil cylinder, hydraulic prop to form thereof, and the slideway on the back timber couples together the upright pendulum sliding-block linkage that wherein back quadric chain is made up of last connecting rod, slide block, upright fork and location-plate; Last connecting rod reaches the upper articulation of upright fork and location-plate respectively with slide block by bearing pin; Upright fork then is connected with back timber by three bearing pins in upper, middle and lower by top, two long arc-shaped holes in middle part and bottom pin-and-hole.Steering hydraulic support of the present invention is when moving frame, two staggered displacements of support body, and move the frame direction by the change in location control of upright fork bearing pin in arcuate socket, promptly a support body supports, receive on the hydraulic prop of a support body, make it break away from top, base plate, make the support body displacement by advancing oil cylinder, change the spacing of its rear end and supporting top beam simultaneously by upright fork swing, regulate the support direction of advance; Support after support body puts in place, at this moment another support body can be shifted, and moves the same.
