(54) GRAVE-DEVICE FOR PACKAGE ELECTRODES

The invention relates to lifting devices designed, in particular, for use in the overload and installation of an electrode package. Closest to the proposed invention is a pick-up device for an electrode package, containing a traverse, hung by means of carrying straps on a hook of a load-lifting mechanism, a plate chain mounted on the traverse, the middle link of each is detachable and fitted with a lock, and fixing elements attached to the traverse are brackets covering chain ij. A disadvantage of this device is that the flat chain in a chained load, must have one-sided rigidity, which significantly complicates the design of the device as a whole. The purpose of the invention is to simplify the design of the device. The goal is achieved by the fact that the locking elements are mounted on the cross beam at a distance from each other equal to the chain pitch, with the axis of each chain hinge coinciding with the axis of attachment of the fixing element, and the lock is made in the form of a fork mounted on the cross bar equipped with spring-loaded latches . In this case, the extreme links of the chain can also be equipped with locks installed at the ends of the traverse. In addition, a half ring can be fixed on the middle link of the chain, covering the axis fixed on the adjacent link. FIG. 1 shows the device, a general view; in fig. 2 - node I, connecting middle chain links with a fork; in fig. 3 - node II, the connection of the extreme chain links with a fork; in FIG. 4, section A-A in FIG. 1. The device comprises a yoke 1 consisting of two longitudinal beams 2 interconnected by transverse beams 3. On the longitudinal heads 2 plates 4 are attached with hooks 5 on which the lower loops of the supporting straps are mounted 6. In the middle part of the supporting straps 6 are installed A dispatched frame 7 with clips 8, which are attached to carrier slings 6. Cables 9 are fastened at one end to the expansion frame 7, and at the other end to the end links of the chain 10. On the plates 4 are installed rollers 11, and on the longitudinal

beams 2 -. fixing elements 12 and 13 / made in the form of brackets. The locking elements 13 are already elements 12.

On and in the middle part of the longitudinal beams 2 grooves are made.

In the grooves made in the middle hour of the TI-beams 2j, the forks 14 are installed, on the gripping part of which there are spring-loaded latches 15, gripping the axis 16 and the bracket 17 fixed on the middle link of one half of the chain 10.

In the grooves made along the edges of the beams 2, the plugs 18 are installed, the PROTECTIVE parts of which are equipped with prefabricated fixtures ai 15, which extend the shafts of the 19 extreme links of the chain 10.

The axis of the middle links of the chain 10 is longer than the other axes and interact when removing both halves of the chain 10 from the pack of electrodes 20 with the extreme locking elements 13.

The device works as follows.

The traverse 1 supplied to the lifting mechanism is lowered onto a package of electrodes 20 assembled on a special stand (not shown), with the brackets of the fixing elements 12 and 13 coinciding with the holes in the package of electrodes 20. The plate chain 10 (gripping organ) passes through the aligned the holes, the axis 16 and the bracket 17 are connected and fixed with a fork 14. The axes 19 of the extreme links of the chain 10 are fixed with forks 18.

Since each link of the chain 10 rests on the locking elements 12 and 13, the chain 10 does not bend.

The captured package of electrodes 20, together with the device on the supporting straps 6, is transferred by a lifting mechanism from the stand and is installed in the electrostatic filter housing. The lifting straps 6 are uncoupled from the hooks 5, lift the forks 14 and 18. With the help of the cables 9, both halves of the chain 10 are pulled out of the package of electrodes 20 up to the stops 16 and the bracket 17 into the extreme locking elements 13. In this position, the device without the package electrodes 20 are transferred to the assembly site of another pack of electrodes.
