Abstract
The utility model belongs to the technical field of coal cutters, and particularly relates to a coal cutter with an auxiliary support. The coal cutter solves the problem that the ground pressure of the existing coal cutter is too large. The coal cutter with the auxiliary support comprises a rack, wherein the middle part of the rack, close to the side of a gob, is connected with a Y-shaped guide hook, and the middle part of the rack, close to the side of a coal wall, is connected with a support shoe travelling on a shovel plate of a scraper conveyor. The coal cutter has the beneficial effects that the overspeed abrasion of a guide shoe and a skid shoe is alleviated, the labor intensity of workers is alleviated, the maintenance time is shortened, potential safety hazards of replacing the guide shoe and the skid shoe underground are eliminated, the frequency of replacing wearing parts is reduced, and the stability of the coal cutter is improved.
Description
Technical field
The utility model belongs to the technical field of coal-winning machine, is specifically related to a kind of coal-winning machine with supplemental support.
Background technology
Height increase along with a mining height of coal mine fully-mechanized mining working, for overcoming cutting resistance and tractive resistance, the power of coal-winning machine needs to improve greatly, the overall weight of coal-winning machine also grows proportionately with power, coal-winning machine power rises to nearly 3000kW by 100kW, and weight is more than 170 ton by about 20 tons surges.
Existing coal-winning machine all adopts two level and smooth boots and 4 supports of two guiding boots, the weight of coal-winning machine is all born by guiding boots, piston shoes, grounding pressure is very big, the subject matter that exists is coal-winning machine guiding boots and piston shoes quick abrasion, changes the frequency height, working strength of workers is big, and potential safety hazard is many, if improved the abrasion resistance of guiding boots and piston shoes, make shovel board and the wearing and tearing of pin rail of the work plane drag conveyor that matches faster, cost is higher; Coal-winning machine poor stability, the attachment bolt between the fuselage are loosening easily, and bolt subtracts disconnectedly when serious, and entire working surface stops production, and production efficiency reduces greatly.
Summary of the invention
The present invention is in order to solve the grounding pressure problems of too of existing coal-winning machine, reduced guiding boots and piston shoes the hypervelocity wearing and tearing, reduced working strength of workers, shortened time of maintaining, eliminated the potential safety hazard that guiding boots, piston shoes are changed in the down-hole, lower the frequency of changing consumable accessory, increased the stability of coal-winning machine.
The present invention adopts following technical scheme to realize:
A kind of coal-winning machine with supplemental support comprises frame, it is characterized in that frame is connected with the fork-shaped guide hook near the middle part of adopting the sky side, and frame is connected with the support boots of walking on the drag conveyor shovel board near the middle part of rib side.
Described frame connects the fork-shaped guide hook by rotational pin.Described frame connects the support boots by the supporting leg junction plate.
The relative prior art of the utility model has following beneficial effect:
1, original structure does not change, and only increases by two supplemental support, and all the other can exchange use fully with intrinsic part.
2, utilize the principle that increases contact area, reduce grounding pressure, improve the force-bearing situation of coal-winning machine, overcome the difficult problem of coal-winning machine piston shoes quick abrasion.
3, reduced the time of changing coal-winning machine guiding boots, piston shoes.
4, solved the difficult problem that the connection place bolt easily becomes flexible.
5, reduce labor strength, eliminated the potential safety hazard that guiding boots, piston shoes are changed in the down-hole.
6, improve the reliability of fully-mechanized mining equipment, increased the effective time of equipment, improved labor productivity.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure: the 1-frame, 2-fork-shaped guide hook, 3-supports boots, 4-rotational pin, 5-supporting leg junction plate.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present utility model is described further.
The coal-winning machine of band supplemental support comprises frame 1, it is characterized in that frame is connected with fork-shaped guide hook 2 near the middle part of adopting the sky side, and frame is connected with the support boots 3 of walking on the drag conveyor shovel board near the middle part of rib side.Frame 1 connects fork-shaped guide hook 2 by rotational pin 4.Frame 1 connects support boots 3 by supporting leg junction plate 5.
The point of attachment of the utility model in the middle of the coal-winning machine increases by two strong points again, by adopt the sky side adopt can swing, weld low-friction coefficient, wear-resisting, satisfied bend fork-shaped guide hook; The support boots that the rib skidding is walked on the drag conveyor shovel board adopt welding low-friction coefficient, structure wear-resisting, that can swing, coal-winning machine stress equalization, smooth running.The utility model can improve stable type, the reliability of equipment, has reduced the grounding pressure of coal-winning machine and becoming flexible of point of attachment bolt, reduces working strength of workers, has improved the efficient of fully-mechanized mining working greatly, has reduced cost.
The utility model is applied to not need to change the original structure of coal-winning machine on the coal-winning machine of coal mine fully-mechanized mining working, can not produce any influence to the Matching Relationship of coal-winning machine and scratch board conveyor.The utility model is big to power, fuselage long, the coal-winning machine of Heavy Weight has good effect.
