Description

SUPPORT UNIT FOR ROTATING CYLINDER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylinder supporting unit, and more particularly, to a cylinder supporting and supporting unit for rotatably supporting a cylinder used in various actuators.

Generally, cylinders are widely used as means for lifting, pushing or pulling an object or for supporting a force.

Such a cylinder has a basic structure capable of expanding and contracting using hydraulic pressure or pneumatic pressure. Cylinders are widely used in various fields such as forklifts, trucks, various kinds of transportation means such as specially equipped vehicles, lifters for lifting objects and people, and various construction equipment.

For example, a plurality of cylinders are used as an actuator for opening and closing a wing door on a vehicle. The cylinder for opening and closing the wing door includes a body to which a fluid line for supplying a working fluid (oil or air) is connected, and a piston rod slidably coupled to the body. The body is rotatably supported at its one end on the skeleton frame of the overhead carriage. The piston rod protrudes outward from the other end of the body and is rotatably supported by a wing door hinged to the skeletal frame of the train.

When the working fluid is injected into the cylinder body through the fluid line, the piston rod is pushed outward by the fluid pressure, so that the wing door is lifted up against the skeleton frame of the top rim to open the wing door. On the other hand, when the wing door is closed, the piston rod slowly moves into the body due to the action of the working fluid, and the wing door gradually moves in the closing direction.

These cylinders are installed in the skeletal frame or the wing door of the vehicle through the support brackets. That is, the body of the cylinder is rotatably mounted on a pivot pin attached to a support bracket fixed to a skeleton frame of the vehicle, and the piston rod of the cylinder is coupled to another support bracket fixed to the wing door The pivot pin is installed to be rotatable about the rotation center axis.

Conventionally, a pivot pin is attached to a support bracket to mount a cylinder, and then a pivot pin is coupled to a support bracket by using a pair of snap rings. That is, after coupling the pivot pin, the snap ring was connected to both ends of the pivot pin using a special tool.

However, the snap ring is thin and thin, making it inconvenient for the operator to handle. And it is easy for the operator to drop the snapping during the operation of combining the snapping with the special tool. Also, since the size of the snap ring is small, it is difficult to find a snap ring that has fallen from a wide work area. Normally, the cylinder manufacturer sells auxiliary materials such as cylinders and support brackets as a packaged product without spare parts, and it is not possible to install the cylinder unless any of the components of the set product is equipped. Therefore, even if it is a simple and small part, if you lose the snap ring, you will have to buy the entire cylinder set again. Also, since the snap ring has a short service life and can not be replaced or repaired, the entire cylinder set must be replaced if the snap ring is broken.
