Description

Invention

refers to lifting mechanisms, in -lacTHOCTH to Pneumatic auxiliary lifting equipment.

Pneumatic lifts are known that contain telescopically articulated sliding cylinders with annular projections and a norm shaft mounted on an oyorp plate.

The purpose of the invention is to increase the reliability of operation and reduce the size of the lift.

This is achieved by the fact that the sliding cylinders are equipped with stator rings, which are fitted externally at least in several upstream cylinders and inlet cylinders, which are attached to the ends of the underlying sliding cylinders, and attached to a support plate to be mounted on the support plates. In addition, the dimensions of the aforementioned plate, tf this, on the razdvpzhny cylinders are put on an elastic protective sheath.

FIG. 1 schematically shows the described pneumatic yan; in fig. 2 - the same.

The base plate / rollers 2 are placed, attached to the croc- ples 3, and also the flange 4, to which the split cylinder 5 is attached, is attached to the base / plate / also attached 6 hectares with a handle 7 .

To t 6 of the middle of the hook 5, the air supply is fixed to the schljg 9, which is inserted into the internal cavity of the cluster 5.

The sliding cylinder 5 telescopically joins the sliding cylinders 10, II, 12, equipped with annular protrusions 13-19, and in this upper sliding center cylinder is built in 1 20 with a brush 21, and one flange 22.

The several overlying sliding cylinders, cylinder cylinders //, 12, have locking rings 23, 24, co1: 1pccaying, mounted on the outside; respectively, with the ends of the annular projections / 5, 17, limiting the cap; they have 11 telescopic upper sliding cylinders: one of the other sliding cylinders (in the off position).

An elastic protective sheath 25 is attached to the support flange22, covering the outside sliding cylinders: Ndra, iredoKhran yup1a nx from contamination of injuries and damages. The end of the elastic shell 25 may be attached to the flange 4.

At the end of the hose there is a valve 26.

The operation of the lift is as follows.

The support plate / with the lift is supplied by the clamp 6 with the handle 7 to the place of lifting the load, for example, to the car.

The support plate is placed on the floor or floor, and the working surface of the rollers is raised above the floor.

The rollers are installed so that when the plits are tilted, to the horizon at an angle of 45 °, their working surfaces are in contact with the ground, and the slab / can be transported on the rollers. Then, compressed air is supplied to the internal cavity of the sliding cylinders, which, acting on the piston 20, lifts it together with the rod 21 and the flange 22, 111, and the weight placed on the flange 22 rises. The annular protrusions 13- / 5 interact with each other, while maintaining the stability of the power axis of the sliding cylinders and 1 of the piston 20 with the brush 21. When the load is lowered, the compressed air bleeds, the sliding cylinders telescopically enter each other, and the circlips 23, 24 descend, meet with the ends of the underlying sliding cylinders and keep them from

“I put it inside these sliding cylinders.”

Subject invention

Pneumatic (lift containing telescopically articulated sliding cylinders with annular protrusions and piston mounted on the base plate, characterized in that, in order to increase reliability and reduce the overall dimensions of the lift, the sliding cylinders are fitted with retaining rings embedded at least outside for several overhead pipes | I | X section VIZH (cylinders and interacting with the ends of the underlying sliding cylinders, and the rollers are attached to the support roller, located on the opposite side of the handle Weaving and outgoing dimensions of the mentioned 1PLITE. At the same time, an elastic protective sheath is put on the sliding cylinders.
