Description

A lifting device for lifting a transport vehicle

technical field

The present invention relates to the technical field of hoisting vehicles, in particular to a lifting device used for hoisting vehicles.

Background technique

The truck-mounted lifting truck can also be called a self-loading and unloading truck. It integrates hoisting and transportation, and is mostly used in stations, warehouses, docks, construction sites, field rescue and other places. Can be equipped with different lengths of cargo boxes and cranes of different tonnages.

The steel pipe transportation of the traditional steel pipe pickling unit is generally carried out by a manually driven ordinary double trolley crane. Since the hoisting wire rope of this manually driven ordinary double trolley crane is a flexible material, the steel pipe shakes very much during the transportation process. It is easy to damage the acid tank or other production equipment, and the accident rate is high.

To this end, the patent specification with publication number CN103350953B discloses a lifting device for a hoisting and transporting vehicle. The lifting and transporting vehicle includes a cart and two rails. Both ends of the cart are arranged on the two rails. The cart can move on two tracks, and the lifting device includes at least two sets of lifting equipment, and at least two sets of lifting equipment are arranged in the cart at equal intervals in a row. Each set of lifting equipment includes a transmission mechanism and two rigid guide columns. , wire rope and lifting mechanism. However, this kind of lifting device used for hoisting and transporting vehicles has shortcomings. The hanging rope often suffers rigid friction during winding, which is easy to cause the hanging rope to break, thereby causing the hanging object to fall, which is not only easy to damage the hanging object, but also There is a big security risk.

A protective box for clamping the suspending rope after the suspending rope is broken is fixed between the two rigid guiding columns through the supporting beam plate. The cross-shaped partition is divided into four working chambers, and the front and rear walls of each working chamber are respectively fixed with a first cylindrical disk and a second cylindrical disk. The front and rear walls are rotatably supported by the supporting blocks, and the two said rotating rods are located in the middle of the rod body outside the disk body with a rope winding groove corresponding to the position. The upper and lower side plates of the box body and the transverse plate portion of the cross-shaped partition plate are provided with perforations that are convenient for the hanging rope to pass through.

Further, in the above-mentioned lifting device for hoisting and transporting vehicles, the protective box is supported by a stainless steel material, and the wall thickness of the box body is 1-2 cm.

Further, in the above-mentioned lifting device for a hoisting and transporting vehicle, the support beam plate is welded with a reinforcing rib at the connection with the rigid guide column and the protective box.

Further, in the above-mentioned lifting device for a lift truck, the axes of the first cylindrical disk and the second cylindrical disk are offset from each other.

Further, in the above-mentioned lifting device for hoisting and transporting vehicles, the inner end of the belt of the spiral metal belt is clamped and fixed with the rotating rod, and the outer diameter of the belt is equal to the inner cavity of the first cylindrical disk or the second cylindrical disk. diameter.

Further, in the above-mentioned lifting device for hoisting and transporting vehicles, the spiral metal strip is a spiral aluminum strip.

The beneficial effects of the present invention are:

The structure of the invention is reasonable in design. The rigid guide column is used as the base to support the protective box, and the suspending rope passes through the protective box. When the suspending rope rises and falls normally and slowly, the rotating rod drives the spiral metal belt on it to rotate slowly along with it; When the rope breaks at the winding place, the sling will quickly fall due to the action of gravity, and the rotation speed of the rotating rod is greater than the adjustment speed of the spiral metal belt itself, which will cause the spiral metal belt to deform, and then the rotating rod will be stuck, and finally the sling will be stuck. Fixed to prevent the hanging objects from falling further and ensure safe production.

Of course, it is not necessary for any product implementing the present invention to achieve all of the above advantages simultaneously.
