Background

In the preparation process of the refractory material, the tunnel kiln is used for roasting green bricks or tile blanks, and the kiln car is used for bearing the green bricks or tile blanks. The electric trailer hauls the kiln car to move on the track of tunnel kiln entry and exit end. The kiln car pushing device is arranged on the electric trailer, and can transversely push out the kiln car from the electric trailer so as to send the kiln car into the tunnel kiln, or pull out the kiln car from the tunnel kiln and send the kiln car onto the electric trailer. The kiln car cart device plays a key role in the transportation process of the kiln car.

At present, a common kiln car pushing device on an electric trailer is a hydraulic cylinder type car pusher. The hydraulic cylinder type car pusher has a complex structure and is driven by a hydraulic cylinder. The hydraulic cylinder type car pusher must be arranged in a limited space between the lower part of the kiln car and the electric trailer frame along the traveling direction of the kiln car. Because the kiln car needs to have the function of pushing and pulling the kiln car in two directions, two sets of hydraulic cylinder type car pushers must be arranged oppositely, so that the original narrow space is more crowded. Meanwhile, the thrust and the stroke of each hydraulic cylinder type car pusher are also limited by the installation size, and the cost of the hydraulic cylinder is obviously increased by selecting the hydraulic cylinder with a large stroke; in addition, the hydraulic cylinder is easy to break down in the using process, and the maintenance period is long. Therefore, when the installation space is small or the production scale is enlarged, the hydraulic cylinder type car pusher cannot meet the requirements. There is a need for a cart device that can set the thrust and stroke according to the process requirements without the limitations of space or equipment type selection.
