Description

one

The invention relates to a lifting machinery industry and can be used directly in gripping devices for lifting and

installation of lengthy products, primarily of beam-type building structures.

A gripping device is known for lifting and installing columns in high-rise building erection conditions, containing a cable suspension, a bar with a pro-tire and eccentrically attached to the bar by means of an axis, a bolt with a cam til. disengagement of the capture with the column.

It is also known gripping device containing rope suspension, rod and eccentric mounted on the rod bolt with a mechanism for fixing it in the off position 2.

The disadvantage of this device is the impossibility of ensuring the vertical orientation of the column and the safety of the rope from the impact of the column during lifting and installation.

The aim of the invention is to improve the reliability of gripping devices.

In the work when lifting the product from a horizontal to a vertical position.

The goal is achieved by the fact that a support frame is installed on the cable mount, which interacts with the upper end of the device, and the bolt locking mechanism is designed as a sleeve that is movably mounted on the rod, interacts with its upper end in the off position.

FIG. 1 shows the device, front view; On fng, 2 - the same, side view.

The proposed device consists of a cable suspension 1, on which the rods 2 and a fixed frame 3 are installed.

The cableway suspension includes a cargo ring 4, connected to it by means of a wheel 5, and a conical sleeve 6, made with lugs in the lower part for fixing the rod.

The rod is made in the form of a cylinder with an eye in the upper part for attachment to the suspension and a groove in the lower part for mounting on the axis of the load girder 7 with the center of gravity shifted eccentrically.

The fixing of the cargo transom in the vertical position is carried out by means of the sleeve 8, which freely moves along the groove along the rod

Frame 3 is made in the form of a spatial structure with a sleeve 9i embedded in it by means of a console through an opening in which the suspension cable is freely passed.

In the assembled position, the grip with its ring is suspended on a crane hook. A rope is attached to the ring on the ring, which passes through the hub of the thrust frame and is fixed to the lower end in a conical sleeve, which is hingedly connected to the eye of the rod with its eyelets. Ka rod installed sleeve and in the groove of the rod longitudinally its axis is the bolt and fixed in the off position by the sleeve.

The device works as follows:

Suspended to the hook of the crane, the hook captures that the lower part of its structures is a resistant frame — it is at the height of the columns laid on the linings with ((the consoles attached to the top) is brought to the upper part of the column. The support frame is put on is inserted into the holes of the column cantilevers and fixed by the bolt in the working position.

Fiscation of capture is done in the following way. A latch bolt is pulled out of the groove of the rod and is brought into contact with the bearing surface of the lower column console.

After the column is installed and secured to the building, the grip is lowered to the level reached for service by the installer, the deadbolt is turned by the sleeve. After that, the grip is taken out of the holes in the column and, with its rise, having touched the sleeve of the thrust frame with the conical sleeve, removes it from the columns.
