Abstract

The utility model provides a scraper which gearbox is provided with parking brake, comprising a gearbox. The scraper is characterized in that the input shaft of the gearbox is provided with a brake which comprises a cylinder, a piston is arrange din the cylinder, a spring is arranged in the piston, one end of the spring is connected with the piston and the another end is connected with the cylinder cover, the top end of the piston is provided with a friction plate which polish plate is abut against the piston and the powder plate is connected with the input shaft, and the side wall of the cylinder is provided with an oil hole. The gearbox and the brake are controlled of oil supply by a vehicle hydraulic control pump, and when the hydraulic control pump stops feeding oil to the drive motor of the gearbox, the brake starts to brake synchronously to realize instant brake and stop the whole scraper. Compared with the prior art, the utility model resolves the parking brake problem of scrapers, having simple operation, simple use, safe and reliable brake.

Description

The scraper of gearbox band parking brake
Technical field
The utility model relates to a kind of scraper of gearbox band parking brake, belongs to the down-hole winning equipment.
Background technology
What the stop device on the existing scraper used all is common pincers dish braking, shortcoming is that security performance is lower, because scraper belongs to large-scale underground equipment, operation in hazardous environments such as the hillside fields of being everlasting again, it is very important therefore how can solving the stopping brake problem better.
Summary of the invention
The purpose of this utility model is to improve the weak point that prior art exists, and a kind of scraper of easy and simple to handle, the gearbox band parking brake that can stop immediately is provided
The technical solution of the utility model is: a kind of scraper of gearbox band parking brake, comprise gearbox, and characteristics are, on the power shaft of gearbox, be provided with brake, brake comprises oil cylinder, is provided with piston in the oil cylinder, is provided with spring in the piston, one end of spring is connected with piston, the other end is connected with oil cylinder cover, is provided with friction plate on the top of piston, and the mating plate and the piston of friction plate are abutted against, the powder sheet is connected with power shaft, is provided with hydraulic fluid port on the sidewall of oil cylinder.
The utility model has been installed brake on gearbox, by vehicle-mounted hydraulic control pump simultaneously to motor and brake fuel feeding, when the hydraulic control pump stops CD-ROM drive motor fuel feeding to gearbox, braking maneuver also takes place in brake simultaneously, instant braking, thereby the braking of realization scraper car load, compared with the prior art, this structure has solved the stopping brake problem of scraper, controls simple, convenience, brakes more safe and reliable.
Below in conjunction with drawings and Examples the utility model is done at length and to be explained.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The explanation of accompanying drawing drawing:
1 spring, 2 friction plates, 3 power shafts, 4 mating plates, 5 powder sheets, 6 oil cylinder covers, 7 gearboxes, 8 oil cylinders, 9 pistons, 10 hydraulic fluid ports, 11 output shafts.
The specific embodiment
Referring to Fig. 1, this scraper comprises the gearbox 7 on the car body, on gearbox 7 brake is installed, brake comprises an oil cylinder 8, be provided with piston 9 in the oil cylinder 8, an end of piston 9 is a hollow-core construction, is provided with spring 1 in it, one end of spring 1 is connected with piston 9, the other end is connected with oil cylinder cover 6, on the top of piston 9 friction plate 2 is set, and the mating plate 4 and the piston 9 of friction plate 2 are abutted against, powder sheet 5 is connected with power shaft 3, is provided with hydraulic fluid port 10 on the sidewall of oil cylinder 8.
Operating principle:
Brake of the present utility model can be by vehicle-mounted hydraulic control pump DFF Direct Fuel Feed, be that the hydraulic control pump is when giving the CD-ROM drive motor fuel feeding of gearbox 7, also give brake oil cylinder 8 fuel feeding by hydraulic fluid port 10 simultaneously by slippage pump, piston 9 retreats under the effect of hydraulic oil, spring 1 is compressed, and the mating plate 4 of friction plate 2 separates with powder sheet 5, removes the braking of friction plate 2, the output shaft 11 of gearbox 7 drives drive axle and rotates, and realizes travelling of scraper; Otherwise when the hydraulic control pump stopped to the CD-ROM drive motor fuel feeding, slippage pump also stopped simultaneously to the brake fuel feeding, under the effect of spring 1, piston 9 advances, and heads on mating plate 4 and is close to powder sheet 5, friction plate 2 begins effect, power shaft 3 brakings of gearbox 7, thereby the braking of realization scraper car load.
