Abstract
The utility model relates to a device for preventing a scraper conveyor from rolling bottom and drifting. The device provided by the utility model is simple in structure, convenient to use, capable of effectively preventing the scraper conveyor from rolling the bottom and drilling. The device disclosed by the utility model comprises a hydraulic oil cylinder, a pushing rod and a pushing seat, wherein the hydraulic oil cylinder is fixedly mounted at the back end of a machine body of the scraper conveyor, a piston rod of the hydraulic oil cylinder is connected with the front end of the pushing rod through a front fixing pin, the back end of the pushing rod is connected with the pushing seat through a back fixing pin, and the pushing rod is connected with the machine body of the scraper conveyor at the position between the front fixing pin and the back fixing pin through a main fixing pin. According to the device disclosed by the utility model, due to the adoption of the structure, the main fixing pin can drive the back end of the machine body of the conveyor to ascend or descend by extension and contraction of the piston rod of the hydraulic oil cylinder, so that pushing force towards the front lower part or the front upper part can be applied to the side of a middle groove shovel plate connected with the front end of the machine body of the scraper and the purpose of preventing drifting or rolling the bottom can be achieved.
Description
Technical field
The utility model relates to a kind of drag conveyor of working along the coal wall in colliery, particularly relates to a kind of anti-anti-slip device that floats in the end that rolls of drag conveyor.
Background technology
In the exploitation transportation in colliery, coal wall; Coal-winning machine is ridden on the drag conveyor body of arranging along the coal wall parallel direction; As shown in Figure 1; The middle pan of scraper conveyor baffle plate 4 ' side channel group is through conveyer passing seat 3 ' direct be connected with the hydraulic support passing cross head 2 ' of hydraulic support pusher rod 1 ' front end (the supporting use of hydraulic support and drag conveyor and coal-winning machine is used to provide shielding support and passing and advances).Yet; Because geological conditions factors such as seam inclination; Said structure makes to be passed structure 1 ', 2 ' by hydraulic support to occur unavoidably in the passing process that drag conveyor rolls at the end (is that The middle pan of scraper conveyor shovel plate 5 ' side down is rolled into base plate or rib; Baffle plate 4 ' side is raised) or float slide (be that The middle pan of scraper conveyor shovel plate 5 ' side is raised, baffle plate 4 ' side reduces, and is the climbing shape) phenomenon and influence normal passing work; Make effectively cut rib of coal-winning machine, cause the significant wastage of coal mining.
The utility model content
In order to solve the problems of the technologies described above, the utility model provide a kind of simple in structure, easy to use, can prevent effectively that drag conveyor from rolling the end or floating the anti-anti-slip device that floats in the end that rolls of the drag conveyor of slide.
The anti-anti-slip device that floats in the end that rolls of the utility model drag conveyor; Comprise hydraulic jack, pusher rod and passing seat; Said hydraulic jack is fixedly mounted on the body rear end of drag conveyor; The piston rod of said hydraulic jack is connected through preceding steady pin with said pusher rod front end, and said pusher rod rear end is connected through the back steady pin with said passing seat, said pusher rod steady pin and saidly afterwards pass through main steady pin between the steady pin and be connected with the body of said drag conveyor before said.
The anti-anti-slip device that floats in the end that rolls of the utility model drag conveyor; Owing to adopt hydraulic cylinder piston rod to link to each other with the pusher rod front end through preceding steady pin; The pusher rod rear end links to each other with the passing seat through the back steady pin, and pusher rod links to each other with the drag conveyor body through main steady pin between forward and backward steady pin, thereby can be through regulating hydraulic cylinder piston rod; Make its elongation or contraction; Thereby make the winner steady pin drive drag conveyor body rear end lifting or decline,, slip or roll end problem to reach floating of the intermediate channel that prevents drag conveyor body front end with a thrust of intermediate channel shovel plate side of connecting for drag conveyor body front end to front lower place or front upper place.
The anti-end of rolling of the utility model drag conveyor, prevent floating slip device, and wherein said pusher rod is a knee.Pusher rod adopts the knee form, is easier to control pusher rod through stretching of control piston bar and rotates around main steady pin, and with better drive conveyer body rear end lifting or reduction, result of use is good.
The anti-end of rolling of the utility model drag conveyor, prevent floating slip device, and wherein said hydraulic jack is installed in the body rear end of drag conveyor through the oil cylinder fixed cover.
Below in conjunction with accompanying drawing the anti-end of rolling of the drag conveyor of the utility model, prevented that floating slip device is described further.
Description of drawings
Fig. 1 is the working state schematic representation that hydraulic support of the prior art is connected with the conveyer intermediate channel;
Fig. 2 is the anti-anti-structural representation that floats slip device in the end that rolls of the utility model drag conveyor;
Fig. 3 is the user mode figure (the piston rod elongation prevents floating slide) of the utility model;
Fig. 4 is the user mode figure (piston rod shrinks, anti-rolling at the end) of the utility model.
The specific embodiment
As shown in Figure 2; The anti-anti-slip device that floats in the end that rolls of the utility model drag conveyor; Comprise hydraulic jack 1, pusher rod 2 and pass seat 3, hydraulic jack 1 is fixedly mounted on body 4 rear ends of drag conveyor through oil cylinder fixed cover 9, and the piston rod 5 of hydraulic jack 1 is connected through preceding steady pin 6 with pusher rod 2 front ends; Pusher rod 2 rear ends are connected through back steady pin 7 with passing seat 3, and pusher rod 2 is connected with the body 4 of drag conveyor through main steady pin 8 between preceding steady pin 6 and back steady pin 7.Pusher rod 2 is a knee.
The anti-end of rolling of the utility model drag conveyor, prevent floating slip device in use; As shown in Figure 3, when the slide problem appearred floating in drag conveyor shovel plate 10 sides, regulator solution compressing cylinder 1 made piston rod 5 elongations; Piston rod 5 drives pusher rod 2 around main steady pin 8 rotations; Make pusher rod 2 low early and high after, thus the drag conveyor body 4 of lifting baffle plate 11 sides, and 12 pairs of passing seats 3 of hydraulic support pusher rod this moment just produce the thrust to the front lower place in drag conveyor baffle plate 11 sides when passing; Thereby force down shovel plate 10 sides, to solve the slide problem of floating of shovel plate 10 sides; As shown in Figure 4, when drag conveyor shovel plate 10 sides the end occurs rolling during problem, regulator solution compressing cylinder 1 shrinks piston rod 5; Piston rod 5 drives pusher rod 2 around main steady pin 8 rotations; High back is low before making pusher rod 2, thereby reduces the drag conveyor body 4 of baffle plate 11 sides, and 12 pairs of this hydraulic support pusher rod are passed when seat 3 is passed and just produced the thrust to the front upper place in drag conveyor baffle plate 11 sides; Thereby lifting shovel plate 10 sides are to solve the end problem of rolling of shovel plate 10 sides.
The utility model compared with prior art; Cancel hydraulic support and passed cross head 2 ' (as shown in Figure 1); Passing seat 3 directly links to each other through bearing pin with hydraulic support pusher rod 12; Make conveyer body 4 can access effective protection of hydraulic support, improved the safety of conveyer body 4 when this device uses, more reliable.
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.
