SU846491A1 - Crossbeam for lifting and carrying drums - Google Patents

Description

one

The invention relates to lifting equipment, namely to cross-arms for lifting drums.

The known traverse is for lifting and transporting drums equipped with a shaft, containing a carrier beam, connected by means of rods with a device for hanging on a hook of a lifting mechanism, and equipped with gripping bodies slings mounted on the beam with the possibility of moving along it 1.

The disadvantage of this device is the lack of productivity of its work, associated with the use of manual labor when installing a-ala in the opening of the disks of the drum.

The goal is to increase productivity.

This goal is achieved by the fact that the bell is made with a shaped groove, and the cables are attached to the beam by means of axles, with one of the axes provided with a pulley to which one of the slings is fixed, and installed with the possibility of movement and fixation in the said groove of the beam and the other sling is rigid and has openings at the end for engaging with said shaft.

In addition, in order to ensure the reliability of its operation, the beam and pulley are equipped with counterbalance counterweights.

FIG. 1 shows the proposed traverse, general view, at the time of installation of the VSE in the holes of the disks of the drum; in fig. 2 - the same, side view; in fig. 3 shows section A-A in FIG. 2

ten

The traverse contains a head 1 with an earring 2 for loading onto a hook of a load-lifting device, pivotally connected to the arms 3 and 4. To grip the ends of the shaft 5 of the drum 6 to the beam 1

15 a rigid sling 7 and a flexible sling 8 are fastened. A rigid sling 7 is made with holes 9 at the end for securing the shaft 5 with the aid of a Kli 10. A flexible sling 8 with a gripping body 11,

 fixed on ykive 12, which has a common axis 13 with a load 4 and is counterbalanced by counterweight 14 through block 15. The total weight of the flexible sling 8 with the gripper op is gan 11, pulley 12, counter load 14 and

 block 15 is balanced by hard

Sling 7 in any position of the earring 2, Axis-13 moves in the shaped groove 16 when lifting the earring 2 with a lifting device dp stop 17, secured to the axis 18, which is turned by the adjustment knob 19 to the required size of the drum. In order to balance the cantilever part of beam 1, the counterweight 20 is moved by a pull 21, pivotally connected to the suspension 4.

Traverse works as follows.

, To install the shaft 5 in the holes and the disks of the drum 6, the tuning knob 19 is rotated in a position corresponding to the size of the drum. The hook of the load-lifting device enters the bracket 2 and, when lifting, the axis 13 with the pulley 12 moves to the corresponding stop 17, at the same time displacing the load 20 by 21 along the beam 1.

By applying a slight force (6-8 kg) to the gripping body 11, the last one rises up. The yoke is moved to the stand for storing the shafts 5, and the end of the pivot is inserted into the corresponding hole 9 in the hard line 7. To prevent the shaft from falling out of the hole, the end of the shaft is fixed by a wedge 10.

After the shaft is installed in the holes of the disks of the drum 6, the wedge 10 is released, the traverse moves to the side along the axis of the drum until the shaft end leaves the holes 9 at the end of the rigid sling 7 and is retracted to the side.

In order to transport the drum 6 with the shaft 5 by applying some force to the gripping body 11, the latter is lowered down, and the gripping bodies of the flexible and rigid slings 7.8 produce, capture and transport the drums in the usual order with a lifting device.

The proposed traverse makes it possible to reduce manual labor when installing the shaft in the holes of the drum disks, manual labor when rearranging the slings to the drum size, reducing the number of required traverse sizes and time for installing the drums during rewinding and cutting to lengths of ropes and cables.

Claims (2)

1. A traverse for lifting and transporting drums equipped with a shaft, containing a carrier beam, is connected to the device for hanging on the hook of a lifting mechanism, and equipped with lifting elements slings mounted on a bulk that can be moved along it, differing in that the purpose of labor productivity, the beam is made with a shaped groove, and the ti are attached to the beam by means of axles, in this case one of the axes is equipped with a pulley to which one of the slings is fixed and installed with the possibility of remescheni and fixing in the aforementioned groove of the beam, and the other sling is rigid and has openings at the end for engaging with said shaft. 2. A traverse according to claim 1, so that in order to ensure the reliability of its operation, the beam and pulley are equipped with balancing koH tr GRU 3.
