A cart machine

Abstract

The application provides a cart machine arranged on one side of a mine car track and used for assisting in pushing the mine car to move forward. The cart machine comprises a frame body, a rotary transmission assembly arranged on the frame body and a cart device. The bottom end of the rotary transmission assembly is higher than the height of the mine car track and lower than the height of the mine car, and the top end is higher than the height of the mine car. One end of the cart device is connected with the rotary transmission assembly, and the other end is horizontally arranged above the mine car track. When the mine car returns and runs below the rotary transmission assembly, the cart machine is started, and the cart device pushes the mine car to move. When the cart device runs above the rotary transmission assembly, the cart device is located at the top end of the rotary transmission assembly. When the mine car is pulled to the yard again, the cart device does not hinder the mine car. Since the cart machine is arranged on one side of the mine car track, even if the cart machine fails, the running mine car on the track will not be affected during maintenance. In addition, the cart machine has a simple structure and relatively low maintenance cost.

[0014] Preferably, the shaft hole connected with the driven shaft is a waist-shaped hole, the bearing seat is connected with the support frame by bolts, and the support frame is provided with waist-shaped bolt holes matched with the bolts.

[0015] Preferably, the trolley device comprises a trolley rod and a conveying link, the conveying link is connected in series on the transmission chain, and one end of the trolley rod is connected with the conveying link.

[0016] Preferably, two conveying links are arranged, the two conveying links are connected in series on the transmission chain after being connected, and the trolley rod is arranged between the two conveying links.

[0017] Preferably, the conveying link comprises a transmission link and an outward arm arranged on both sides of the transmission link, and the outward arm is provided with a fastener for fixing the trolley rod.

[0018] Preferably, the reduction motor is fixedly connected with the support frame through a fixing support.

[0019] Preferably, the support frame is a channel steel, and the opening ends of the two channel steels face opposite directions.

[0020] Preferably, a plurality of reinforcing ribs are distributed along the length direction of the channel steel between the two channel steels.

[0021] The trolley machine provided by the application has the following beneficial effects:

[0022] The application provides a trolley machine arranged on one side of a mine car track, which is used for assisting in pushing a mine car to move during a return process of the mine car after being pulled to a car yard to complete unloading, and comprises a frame, a rotary transmission assembly and a trolley device. The frame extends along the extension direction of the mine car track. The rotary transmission assembly is arranged on the frame.

The running direction of the bottom end of the rotary transmission assembly is along the moving direction of the mine car. The running direction of the top end of the rotary transmission assembly is opposite to the moving direction of the mine car. Since the rotary transmission assembly is higher than the height of the mine car track and lower than the height of the mine car, when the rotary transmission assembly runs, the trolley device horizontally arranged above the mine car track pushes the mine car below the rotary transmission assembly to move.

Even if the trolley machine fails, since the trolley machine is not arranged on the mine car track, the track is not occupied during maintenance, and the running of the mine car on the track is not affected. Moreover, the trolley machine has a simple structure and relatively low maintenance cost.
