Abstract

LOADING DEVICE, containing a traverse with a loop for hanging the crane, connected to the traverse by means of an axis with the possibility of rotation of the gripping body and the mechanism of tilting the gripping body, which has a copier with a groove characterized by the fact that the traverse is made in a j-shaped manner and the copier is rigidly fixed on it, the gripping body has a frame containing tubular struts connected by an axis placed in a sleeve rigidly fixed on the copier, placed with the possibility of longitudinal movement. In the frame racks, a fork with spring-loaded pick-up legs in the lower part and a jumper with a roller rigidly connected to the upper part of the fork, mounted with the possibility of movement along the copier groove.

The invention relates to lifting devices and is intended for transporting glazed window and door blocks and installing them in the openings of wall panels.

A load gripping device is known in 5 containing a cross bar with a loop for hanging on a crane hook connected to the cross bar by means of an axis with the possibility of rotation of the gripping body and the mechanism of inclination of the gripping body, including a copier with a notch f 3 "

A disadvantage of the known device is the inconvenience of operation.

The purpose of the invention is to increase ease of operation.

To achieve this goal, a load gripping device containing a yoke with a loop for hanging on a crane hook, connected to the yoke through an axis can be turned a gripping body, and a tilt mechanism of the gripping body having a copier with a notch It, the gripping body has a frame containing tubular racks connected by an axis placed in a sleeve rigidly mounted on a copier, placed with the possibility of longitudinal movement in the frame racks of a fork with springs At the bottom of the raised legs are a jumper with a roller rigidly connected to the upper part of the plug, which is installed with the possibility of moving along the groove of the copier.

FIG. 1 shows a load gripping device, asciometric; in FIG. 2, node 1 in FIG. 1 | Fig "3 - section in figure 2 | figure 4 - section bb on figZ; FIG. 5 shows the node P in FIG. 1 in FIG. 6 a load gripping device with a load (block u); in Fig. 7, the same front view in Fig. 8 is a diagram of the installation of the load (block).

The load gripping device contains a 3-shaped traverse 1, made of thin-walled pipes, reinforced by connections 2.

In the upper part of the L-shaped traverse 1, a loop 3 is rigidly fixed for hanging on the crane hook, in the middle inner part a stop 4 is rigidly mounted to limit the inclination of the load, made of a plate fixed to the rack 5. At the bottom

the crosspiece 1 is rigidly fixed to a copier 6 made of two plates with arcuate grooves, the plates being provided with stiffening ribs framing the grooves.

On the copier 6 is rigidly fixed. the sleeve 7 is made in the form of a pipe, with the axis of the gripping body placed in it.

The gripping member includes a frame containing tubular supports 8, connected by jumpers 9, the upper of which, being the axis of the gripping organ, is housed in said sleeve 7 and a fork 10 arranged with the possibility of longitudinal movement in the supports 8-.

The fork 10 in the lower part is made with the claws 11 of plates with stiffening ribs 12, fitted with springs .13, the upper ends of which are fixed on the vertical tubular supports 8, and in the upper part the fork 10 is rigidly connected by means of lugs 14 to the web 15, equipped with a roller 16 and limiters 17 for horizontal movement of the roller along the web.

The device works as follows.

For loop 3 on traverse 1, the lifting device is hung on the crane hook, after which it is guided to the window or door block installed vertically on the linings. The legs are inserted under the base of the block and the device is raised.

Raising the loop 3 of the J-shaped yoke 1 carries along the frame connected to it by means of a jumper axis: ki 9, consisting of tubular supports 8. The legs 1I under the action of the load remain stationary when. .. this spring 13 is stretched, and the jumper 15, interacting with the help of the roller 16 with the groove of the copier 6, leads the gripping body with the block to an inclined position. The further tilting of the blocks is limited by the stop 4, on which the blocks rest on the upper transverse flight, without touching the glass.

At the moment when the jumper. 15 occupies the lower position in the groove of the copier 6, the center of the body of the block lies inside the crosspiece 1 and the device with

This is detached from the workshop floor in a stable, inclined position.

Then the device with the block is moved to the conveyor, in which the wall panel is installed in the building berth.

Move the device with the unit to the panel opening and wind the lower part of the unit into the opening on the pre-packed seals and wedge gaskets. Paws 11 made of plates allow insertion of the lower part of the block to be installed, after which the tension of the device is relaxed, the upper part of the block is brought to the design position with a small effort of the working unit, and lifting legs 11 are pulled out from under the block.

The action of the action of springs 13 fork 10 displacing. In vertical pipes 64L

racks 8 up, moving jumper 15 with roller 16 along the groove of the copier, returning the gripping body to its original position.

The design of the device allows to transport and install the glazed table blocks in a convenient position, close to

vertical with minimal manual costs, without violating safety conditions. The design feature of the proposed device provides for tilting the blocks and moving its center of gravity relative to the suspension point inside the traverse, which leads to a mandatory, stable position of the blocks during lifting and moving.
