Abstract
The utility model discloses an adjusting device of a scraper conveyor. The scraper conveyor is hinged to a hydraulic support through a horizontally arranged hydraulic pushing rod, and a hydraulic oil cylinder is arranged between the scraper conveyor and the hydraulic support. A hinged base is arranged on the scraper conveyor, the hydraulic support is provided with a lower hinged base, a circular hole in the retractable end of the hydraulic cylinder is hinged to the upper hinged base through a hinge pin, and a circular hole in the fixed end of the hydraulic oil cylinder is hinged to the lower hinged base through a hinge pin. When the bottom of the scraper conveyor needs to be lifted or horizontally placed, the liquid is supplied to the hydraulic oil cylinder, the retractable end of the hydraulic oil cylinder extends outwards or retracts inwards to drive the scraper conveyor to rotate around the hinged point of the scraper conveyor and the hydraulic pushing rod, and then bottom lifting or bottom horizontally placed of the scraper conveyor is achieved. The scraper conveyor occupies small space, and is wide in adaptability, easy to operate, flexible in usage and suitable for the bottom lifting of the scraper conveyor under the complex geological condition or a working plane under the pitching exploiting condition.
Description
Technical field
The utility model relates to the adjusting device in coal mining field, particularly a kind of drag conveyor.
Background technology
China is the main producing coal country in the world, and colliery sum surpasses other All Countries colliery number sums of the whole world, and comprehensive mechanical coal mining also becomes the main method that coal seam is exploited.
Comprehensive mechanical coal mining equipment at coal-face is mainly comprised of coal-winning machine, drag conveyor and hydraulic support three.Drag conveyor is the work plane haulage device of comprehensive mechanical coal mining, and its major function is to transport the coal of adopting.Hydraulic support is the support apparatus of comprehensive mechanical coal mining, and supporting stope top board, safeguards the working space of the equipment such as coal-winning machine and drag conveyor, and promote coal excavation apparatus and the reach of self.The equipment connections such as the general and drag conveyor of the front end pusher rod of hydraulic support, realize performing comprehensive coal mining.
For the comprehensive mechanical coal mining equipment of coal-face, due to self structure restriction, be not all equipped with in the ordinary course of things the adjusting device that drag conveyor is lifted the end and pitching.Therefore, as run into the situation of features as poor geologic condition at down-hole coal excavation work plane, when hydraulic support or drag conveyor base front end sink, cannot normally pushing and sliding pusher rod.Now, for hydraulic support, often by taking the mode that increases bottom lifting device to solve the end problem of lifting of himself, for relevant devices such as drag conveyors, cannot solve, mostly can only by lift by crane sagging drag conveyor then the method such as chock plug, steel plate solve, such method wastes time and energy, and workload is large, has increased unnecessary cost.
Utility model content
The technical problem solving:
Technical scheme: for solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of adjusting device of drag conveyor, the telescopic end of drag conveyor and horizontally disposed hydraulic pressure pusher rod is hinged, the fixed end of hydraulic pressure pusher rod is fixed on hydraulic support front end, between drag conveyor and hydraulic support, hydraulic jack is set, on the telescopic end of described hydraulic jack and fixed end, is equipped with circular hole; Described drag conveyor is provided with upper hinge seat, and upper hinge seat is positioned at the top of drag conveyor and hydraulic pressure pusher rod pin joint, and described hydraulic support is provided with lower hinge seat, and lower hinge seat is positioned at hydraulic support front end; The circular hole of the telescopic end of described hydraulic jack and upper hinge seat are hinged by bearing pin, and the circular hole of the fixed end of described hydraulic jack and lower hinge seat are hinged by bearing pin.
Further, in the utility model, the axis direction of described circular hole is vertical with the axis direction of hydraulic jack.
Beneficial effect: the adjusting device of the drag conveyor that the utility model provides, because the telescopic end of hydraulic jack is connected with the upper hinged seat of drag conveyor by bearing pin, fixed end is connected with the lower hinged seat of hydraulic support.When needs are lifted the end or planted agent to drag conveyor, to hydraulic jack feed flow, the telescopic end of hydraulic jack is overhanging or inside contract, thereby drives drag conveyor around the pin joint rotation of drag conveyor and hydraulic pressure pusher rod, and that realizes drag conveyor lifts the end or planted agent.Due to this device take up room little, wide adaptability, simple to operate, use flexibly, be suitable for the work plane that drag conveyor under Complicated Geologic Condition is lifted the end or had pitching exploitation situation.Than the method for traditional lifting, saved the manpower and materials of artificial lifting drag conveyor, choker block wood, paving steel plate, save man-hour, reduced cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation while lifting the end of the present utility model;
Structural representation when Fig. 3 is planted agent of the present utility model;
Fig. 4 is the structural representation of hydraulic jack in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of adjusting device of drag conveyor, described drag conveyor 1 is hinged with the telescopic end of horizontally disposed hydraulic pressure pusher rod 7, the fixed end of hydraulic pressure pusher rod 7 is fixed on hydraulic support 2 front ends, between drag conveyor 1 and hydraulic support 2, hydraulic jack 3 is set, on the telescopic end of described hydraulic jack 3 and fixed end, be equipped with circular hole, and the axis direction of described circular hole is vertical with the axis direction of hydraulic jack 3.Described drag conveyor 1 is provided with upper hinge seat 4, upper hinge seat 4 is positioned at the top of drag conveyor 1 and hydraulic pressure pusher rod 7 pin joints, described hydraulic support 2 is provided with lower hinge seat 5, lower hinge seat 5 is positioned at hydraulic support 2 front ends, the circular hole of the telescopic end of described hydraulic jack 3 and upper hinge seat 4 are hinged by bearing pin 6, and the circular hole of the fixed end of described hydraulic jack 3 and lower hinge seat 5 are hinged by bearing pin 6.
In the course of the work, when drag conveyor 1 need to be lifted the end, the expansion link of hydraulic jack 3 shortens, and pulls drag conveyor 1 to rotate around the pin joint of drag conveyor and hydraulic pressure pusher rod 7, makes the lifting of drag conveyor leading portion.Then the advancing jack (not shown) of hydraulic support 2 is extended, and promotes hydraulic pressure pusher rod 7 and moves forward and then promote drag conveyor 1 reach, realizes drag conveyor 1 and lifts the end.
In the course of the work, when drag conveyor 1 need to be acted as a planted agent, the expansion link of hydraulic jack 3 extends, and promotes drag conveyor 1 and rotates around the pin joint of drag conveyor and hydraulic pressure pusher rod 7, and drag conveyor is crouched for 1 time.Then the advancing jack (not shown) of hydraulic support 2 is extended, and promotes hydraulic pressure pusher rod 7 and moves forward and then promote drag conveyor 1 reach, realizes drag conveyor 1 planted agent.
Hydraulic jack 3 flexible can make drag conveyor 1 around its with the pin joint of hydraulic pressure pusher rod 7 centered by, in vertical plane, rotate-10 °～10 °.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
