Oil-pressure chain combined type push-and-pull vehicle mechanism

Abstract

The invention relates to a push-and-pull vehicle device, which is arranged on a trolley of a kiln vehicle in a conveying parallel rail and is used for pushing and pulling the kiln vehicle. In the device, two groups of front and rear moveable pulleys are arranged on a rigid member and are driven by an oil cylinder; a chain is connected with a support capable of adjusting the elasticity of the chain after winding the front and rear moveable pulleys and then is fixed on a trolley frame; the two ends of the push-and-pull vehicle used for pushing and pulling the kiln vehicle are hinged with the chain and horizontally moves forward and backward along with the chain; a convex plate used for controlling the push-and-pull vehicle to push and pull the vehicle is arranged on the rigid member which is connected with the front and rear moveable pulleys; and one end of an anti-dumping device and an anti-equilibrium device are arranged on the trolley frame. The device has the characteristics of large thrust, long travel of the push-and-pull vehicle and stable action during pushing and pulling the vehicle. After the device is arranged on the trolley, the kiln vehicle can be pulled on the trolley; the whole array of the kiln vehicle group can be pushed continuously after the kiln vehicle is pushed out of the trolley; and the area and self-gravity of the equipment are reduced by over a half. The device is also applied to equipment which has the requirements on large thrust, long travel and stable movement in the horizontal direction.

Description

1. Technical field [0001] The invention relates to a push-pull car mechanism installed on a trolley, in particular to a push-pull car device for pushing and pulling a kiln car installed on a trolley for transferring kiln cars in parallel tracks. 2. Background technology [0002] 1. The existing push-pull cart mechanisms installed on the trolley mainly include the direct push type of the oil cylinder, the sprocket chain connection push plate type, and the sprocket chain oil cylinder push forward double-station combined type. The equipment has a single action, low production efficiency, and occupies an area of ​​​​and The volume is large, and the kiln car has to be manually fed into the trolley, and the cart is not stable enough when it works, which may easily cause the goods on the kiln car to collapse and increase the production cost.

Problems solved by technology

[0002] 1. The existing push-pull cart mechanisms installed on the trolley mainly include the direct push type of the oil cylinder, the sprocket chain connection push plate type, and the sprocket chain oil cylinder push forward double-station combined type. The equipment has a single action, low production efficiency, and occupies an area of ​​​​and The volume is large, and the kiln car must be manually fed into the trolley, and the cart is not stable enough to work, which may easily cause the goods on the kiln car to collapse and increase the production cost.

[0003] 2. The movable pulley stroke amplification mechanism is usually used in vertical movement, and the mechanism works in one direction. The return stroke adopts passive reset, and the accuracy of the return stroke is difficult to guarantee.

For example, "Mechanical Design Handbook" "Second Volume", Chemical Industry Press 1991 reprint, the mechanisms shown in Figure 7-143 and Figure 7-144 on page P181 of the third chapter, respectively rely on springs or self-resetting, and cannot be in the horizontal direction. Simultaneously complete the task of high thrust and two-way work
