Anti-leakage sand automatic sand spreading device for mine electric locomotive

Abstract

The invention relates to a mining electric locomotive leak-proof automatic stuccoing device belonging to an electric locomotive leak-proof automatic stuccoing device. The device is mainly used for solving technical problems of sand falling and leakage of existing devices. The invention adopts a technical scheme that: the bottom plate of a sand body (1) and the top plate of a stuccoing box (5) are connected with the top of one side of a power device support plate (7); the other side of the power device support plate (7) is fixedly connected with a powder device (2); below the power device support plate (7), one side of the powder device (2) is fixedly connected with a spring (3); a powder shaft (6) connected with the power device (2) and crossing the stuccoing box (5) is surrounded on the inner side of the spring (3); the spring (3) is fixedly connected with a side plate of the stuccoing box (5); and a sealing plate (4) matching a round outlet of the top plate of the stuccoing box (5) is fixedly arranged on the power shaft (6). The device provided by the invention is mainly used in electric locomotive stuccoing.

Description

Technical field [0001] The invention relates to a sand-spreading device for electric locomotives, in particular to an automatic sand-spreading device for preventing sand leakage for electric locomotives. Background technique [0002] At present, the existing railway locomotives can safely brake during operation. Usually, a sanding device is installed on the four corners of each bogie of the locomotive. The sanding device can scatter sand between the wheels and the rails, increasing The adhesion between the two prevents wheels from slipping and scratches on the surface of the wheel; ideally, a constant amount of sand should be spread per meter of travel. If too much or too little sand is spread, the optimum will not be achieved. The anti-slip effect. Therefore, under the premise of ordinary sand sprinkling control devices, it is necessary to control the amount of sand sprinkling to minimize sand loss and sand leakage to prevent accidents. For example, the Golden Tiger of CSR Zhu...

Problems solved by technology

For example, Huang Jinhu of CSR Zhuzhou Electric Locomotive Co., Ltd. applied on September 2, 2011, and the application number published on June 6, 2012 is the patent of CN201120326818 "a sand spreading device for locomotives", which includes sand boxes, sensors and equipment. There is a sanding controller on the lower side of the sand box to control the amount of sanding. The sand inlet on the top of the sanding controller is connected to the outlet of the sanding box. The sensor is connected to the speed signal processing module and the central processing module controls the speed of the motor. Sanding There is a sand outlet on the lower side of the inner gear of the controller, which has the advantages of good anti-skid effect, but it also has the problems of too complicated structure, inconvenient operation and high production cost
