Description
Technical field
The present invention relates to a kind of scraper plate hauler, it is specifically related to a kind of for 60 degree of deep inclined thin coal seam fully-mechanized mining working scraper conveyors.
Background technology
Along with the development of coal mine work production technique, the demand for special seam mining technology is more and more urgent. Scraping trigger is one of important equipment of fully-mechanized mining working, fully-mechanized mining working except coalingging, transporting coal also for coalcutter walk offer machine road, simultaneously for pushing and sliding and move frame provide support a little. Special coal seam is scraped trigger and is developed along with the development of production technique, and little mining height scrapes trigger and high spud angle is scraped trigger and in succession entered coal machine market in recent years. But can adapt to simultaneously high spud angle and little height mining face to scrape trigger few, and at present can reach 55 degree to the adaptation at working face inclination angle is maximum, pin row was arranged on above middle trough ledge in the past, highly higher, thin seam scrapes the seam mining that the minimum mining height of trigger also can only adapt to 1.1m, and it is a difficult problem that deep inclined thin coal seam scrapes trigger all the time.
For the little mining height scraper conveyor of high spud angle, technical barrier following points:
1, complete machine sliding force is big; 2, head lubrication problem is difficult to solve; 3, coal block scrape in trigger chute easily rolling damage equipment and hurt sb.'s feelings 4, coalcutter walk time, tractive force is big; 5, motor is in generator operation in operation, difficulty of stopping, and well work operation space is little. Existing market does not also have to overcome an above-mentioned difficult problem and provide a kind of inclination angle that can be used for be greater than 55 degree and be the scraper conveyor being less than 1.1m with the supporting minimum mining height of machine of adopting.
Summary of the invention
The present invention is directed to prior art and can not overcome an above-mentioned difficult problem, and a kind of scraper conveyor for 60 degree of deep inclined thin coal seam fully-mechanized mining workings is provided, it can be used for 60 degree, inclination angle and be the scraper conveyor of 0.9m with the supporting minimum mining height of machine of adopting, the geologic condition being applicable to be less than 60 degree of little height mining faces, and safe and reliable to operation.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of scraper conveyor for 60 degree of deep inclined thin coal seam fully-mechanized mining workings; comprise that head driving section always becomes, tail driving section and be connected to the scraper plate that head driving section always becomes the ramp pan between tail driving section, middle trough, intermediate section groove for opening clearstory chain and be arranged on chain; described head driving section always becomes and is equipped with retarding disc on the shaft coupling of the power part with tail driving section, and head driving section always becomes the power part with tail driving section to connect to be provided with stop block device open in usual on cover cylinder inwall.
Described stop block device open in usual comprises mechanical part and electrolyte control part; mechanical part is made up of cylinder body, the plunger being evenly arranged in cylinder body and the disc spring that is arranged between plunger end and cylinder body, and electrolyte control part is made up of the electric hydraulic control valve being connected with motor, the fluid-valve being connected with electric hydraulic control valve and tensimeter.
Described middle trough both sides are provided with ledge, are provided with the anti-draw runner of profile of tooth bottom ledge.
Described scraper chain is two, and two scraper chains are symmetricly set on both sides, scraper plate axis, and two scraper chain spacing are 250mm.
Described middle trough side is provided with pin row, and pin row is installed on inside middle trough ledge.
The present invention utilizes the principle of friction clutch coupling, power part high speed axle place design retarding disc in the assembly of transfer roller driving section, stop block device open in usual is designed at connection cover cylinder inwall, avoid and shut down difficulty, complete machine middle trough ledge bottom surface is designed to the anti-draw runner of profile of tooth, slip resistance under raising transfer roller, it is to increase transfer roller adapts to be not more than the ability at 60 �� of inclination angles; The design of accurate double center chain scraper plate, increases space of coalingging, further prevents lump coal from tumbling; Adopting horizontal pin row structure, supporting with little mining-height coal mining machine, machine height is about 675mm, greatly strengthens transfer roller to the adaptive faculty of thin seam, and mining height can reach 0.8m.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Fig. 1-Fig. 7, a kind of scraper conveyor for 60 degree of deep inclined thin coal seam fully-mechanized mining workings, comprise head driving section and always become 1, tail driving section 6 and be connected to head driving section and always become the ramp pan 2 between 1 and tail driving section 6, middle trough 3, intermediate section groove for opening clearstory chain 5 and the scraper plate 4 being arranged on chain, head driving section always become 1 and tail driving section 6 power part shaft coupling 7 on be equipped with retarding disc 8, retarding disc 8 and shaft coupling 7 are connected into one by bolt 9 and bearing pin by retarding disc 8, head driving section always become 1 and the power part of tail driving section 6 connect on cover cylinder 10 inwall and be provided with stop block device open in usual, stop block device open in usual comprises mechanical part 11 and electrolyte control part, wherein mechanical part 11 is by cylinder body 12, the plunger 13 being evenly arranged in cylinder body 12 and the disc spring 14 being arranged between plunger 13 end and cylinder body 12 are formed, plunger 13 end face and retarding disc 8 are compressed by the preliminary tension of application disc spring 14, multiple plunger 13 is evenly distributed on cylinder body 12, make retarding disc 8 uniform force, and enough friction resistances can be provided, braking is reliable, electrolyte control part is made up of the electric hydraulic control valve 16 being connected with motor 15, the fluid-valve 17 being connected with electric hydraulic control valve 16 and tensimeter 18. the present invention applies the principle of friction clutch coupling, power part high speed axle place design retarding disc in the assembly of transfer roller driving section, stop block device open in usual is designed at connection cover cylinder inwall, this device can realize shutdown and automatically lock scraper conveyor, the scraper plate problem such as operation automatically when preventing from shutting down difficulty, driving and maintenance.
