Description

Technical Field

[0001] The utility model relates to the technical field of sand feeding devices, in particular to a locomotive mobile sand feeding device. Background Art

[0002] With the rapid development of railway transportation, locomotives, as the core equipment of railway transportation, have received widespread attention for their operating efficiency and safety. During the starting and braking process of electric locomotives, sand is usually sprinkled on the rails to increase the friction between the wheels and the rails. Sand is stored in the sand box of the electric locomotive and needs to be added to the sand box during locomotive maintenance. Locomotive sanding operations are an important part of locomotive maintenance and are of great significance for ensuring the normal operation of the locomotive. Currently, there are two common methods for adding sand to the sand box of electric locomotives: manual sanding and mechanical automatic sanding.

[0003] While manual sanding is simple to operate, it is inefficient, labor-intensive, and prone to uneven sanding due to human factors. Manual sanding takes approximately 30 minutes per locomotive, and the amount of sand applied is difficult to precisely control, resulting in waste.

[0004] Mechanical sanding uses automated pneumatic conveying equipment to evenly distribute sand, improving both efficiency and accuracy. However, the purchase and maintenance costs of mechanical sanding equipment are high, and they are typically deployed on both sides of the track being sanded. When a locomotive is sanding, a sand-feeding locomotive must be deployed to that track, making the sanding process cumbersome.

[0005] Therefore, a locomotive mobile sand loading equipment has become a problem that needs to be solved urgently. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a locomotive mobile sand-feeding device, which can reduce the labor intensity of manual sand-feeding, is flexible to operate, can be interspersed between tracks in the preparation yard, and has the characteristics of easy use, flexible operation, and low manufacturing and maintenance costs.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a locomotive mobile sand loading equipment, including an electric flat car, a sand box, a conveying device and a control device,

[0008] The sand box is fixed on an electric flat car, and a fixed bracket is provided inside the sand box;

[0009] The conveying device includes a conveying motor, a spiral hinge wheel and a shell. The shell is fixed in the sand box by a fixing bracket. The lower part of the shell is provided with a feed port, and the upper part of the shell is provided with a discharge port. The conveying motor is fixed on the shell. The spiral hinge wheel is arranged inside the shell and is transmission-connected to the conveying motor.

[0010] The control device includes a controller, a battery and a remote controller. The controller is electrically connected to the battery, the controller is wirelessly connected to the remote controller, and the controller is electrically connected to the conveying motor.

[0011] Furthermore, a funnel cavity is provided at the bottom of the sand box, and the lower end of the shell is fixed inside the funnel cavity.

[0012] Furthermore, a first sprocket is provided at the power output end of the conveying motor, a second sprocket is provided at the end of the spiral hinge wheel, and the first sprocket and the second sprocket are connected via a chain transmission.

[0013] Furthermore, the spiral hinge wheel includes a main shaft and spiral blades, the main shaft is rotatably connected to both ends of the shell, the second sprocket is arranged at the end of the main shaft, and the spiral blades are arranged spirally around the main shaft.

[0014] Furthermore, the discharge port is provided with a rotary joint, and the rotary joint is provided with a sand adding hose.

[0015] The advantages of the utility model compared with the prior art are that the utility model can adaptively move the sand loading device through the electric flat car, so that the sand loading device can flexibly load sand according to the parking position of the electric locomotive, has high sand loading efficiency, strong operational adaptability, and low operating and maintenance costs, and effectively solves the problems of high labor intensity of manual sand loading and high investment in mechanical sand loading equipment.
