Abstract
The utility model relates to the field of fully-mechanized coal mining equipment in an underground coal mine, and discloses a hydraulic brake disc for a scraper machine. The hydraulic brake disc for the scraper machine comprises an oil cylinder, two clamp arms, a brake piece and a brake disc. The oil cylinder and the brake piece are hinged to the clamp arms, the oil cylinder is used as a motive power to achieve closing or opening of the brake disc, clamping and loosening actions of the brake disc are achieved through stretch and retraction of the oil cylinder, and working directions of the oil cylinder is controlled through a hydraulic direction-changing valve, so that tight chains work fast, and the labor intensity of underground workers is reduced.
Description
Technical field
Slat conveyer is fully-mechanized mining equipment under the coal mine, scraper plate captain time service, and loose phenomenon can appear in chain, thereby influences the work efficiency of slat conveyer, so must carry out tight chain work.Brake disc is the critical component of finishing tight chain work.
Background technology
Used brake disc is manually, belongs to mechanical, and workman's operation is effort, the more important thing is and can not satisfy modern mine to the requirement of High-efficient Production.
The utility model content
The armstrong's patent brake disc that prior art adopts moves inward brake plate by the M/C tong arm, by friction brake disc is stopped operating, and then carries out tight chain, pinch chain work of scraper plate machine, and cutter's labour intensity is big, inefficiency.The utility model provides and can reduce labor strength, the brake disc of increasing work efficiency.For the labour intensity that reduces the down-hole cutter, increase work efficiency, the utility model scraper plate machine hydraulic pressure brake disc, it comprises: oil cylinder, two tong arms, brake plate and brake discs; Described oil cylinder and brake plate are hinged on the tong arm, realize the closure of brake disc/unclamp with oil cylinder as power.With fluid pressure type substitute mechanical type, with the service direction of hydraulic directional control valve control oil cylinder, thereby realize the closure of brake disc/unclamp.
Description of drawings
Fig. 1 is the scheme drawing that the utility model scraper plate machine is used the hydraulic pressure brake disc;
Among the figure, 1: oil cylinder; 2: tong arm; 3: brake plate; 4: brake disc.
The specific embodiment
As shown in Figure 1, oil cylinder 1 and brake plate 3 are hinged on the tong arm 2, and oil cylinder 1 shrinks two tong arms 2 moves inward brake plate 3, by friction brake disc 4 is stopped operating, and then carry out tight chain, pinch chain work of scraper plate machine; When oil cylinder 1 piston rod stretches out, brake plate 3 outside mobile take-off the brake dishes 4, the scraper plate machine can carry out normal operation.
Claims (1)
1. scraper plate machine hydraulic pressure brake disc, it is characterized in that: it comprises: oil cylinder, two tong arms, brake plate and brake discs; Described oil cylinder and brake plate are hinged on the tong arm, realize the closure of brake disc/unclamp with oil cylinder as power.
