Description

Special spreader for large dry-type air-core reactor

technical field

The utility model relates to a sling, in particular to a special sling for a large dry-type hollow reactor.

Background technique

Large dry-type air-core reactors are mainly used in converter stations or substations. As shown in Figure 1, these reactors weigh tens of tons and are bulky. During the hoisting process, due to their large weight, large volume, and high center of gravity , The number of support points is large, compared with the installation of ordinary dry-type air-core reactors, it has the characteristics of difficult control of installation accuracy and difficult control of hoisting stability. Ordinary dry-type air-core reactors are hoisted by steel wire ropes or slings, with few hoisting points, uneven force, poor hoisting stability, and certain safety risks in hoisting.

Utility model content

The purpose of the utility model is to provide a special hoisting tool for large-scale dry-type air-core reactor, which has the characteristics of many hoisting points, uniform force, and strong hoisting stability.

The above purpose of the utility model is achieved through the following technical solutions: a special spreader for large dry-type air-core reactors, including a spreader frame, the spreader frame is a star structure, the spreader frame includes multiple booms, The bottom of the tool frame is fixed with an annular protrusion, and an annular T-shaped groove is arranged inside the annular protrusion. The T-shaped groove, the annular protrusion, and the spreader frame are all concentrically arranged, and there are multiple moving sliders in the T-shaped groove. There is a hanging claw under the moving slider.

By adopting the above technical scheme, by setting an annular protrusion under the spreader frame, and processing an annular T-shaped groove channel in the annular protrusion, the hanging claw is fixed under the moving slider in the T-shaped groove through the connecting piece, A plurality of moving sliders are set in the T-shaped slot, and each moving slider is provided with a hanging claw, which is connected to the star frame on the large dry-type air-core reactor by bolts, and the multiple hanging claws can be moved along the The ring-shaped T-slot is moved to the installation hole of the star frame of the reactor and fixed. Since there are many lifting claws and the fixed points on the star frame of the reactor are designed symmetrically, the force of the spreader is uniform during hoisting and the hoisting is stable. Strong.

Preferably, grooves are provided on both sides of the annular protrusion, and a connecting block is welded and fixed on the lower surface of each moving slider, and clamping rods hooked into the grooves are fixed on both sides of the connecting block.

By adopting the above technical scheme, by setting a clamping rod on both sides of the connecting block and hooking the clamping rods into the grooves opened on both sides of the connecting block, the pulling force on the lifting claw can be shared to a certain extent, and the lifting gear can be strengthened. lifting load.

Preferably, a reinforcing rib is provided between the clamping rod and the connecting block.

By adopting the above technical solution, the connection strength between the clamp rod and the connection block can be improved.

Preferably, two reinforcing ribs are provided at the right-angled side inside the hanging claw.

By adopting the above technical proposal, the structural strength of the hanging claw can be improved, and the lifting stability can be enhanced.

In summary, the utility model has the following beneficial effects:

It has the characteristics of high stability and strong safety for hoisting large dry-type vacuum reactors.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

A special spreader for large dry-type hollow reactors, as shown in the figure, this type of reactor special spreader includes a spreader frame 1, which is composed of multiple booms 11, the spreader frame 1 and the reactor The star racks 8 have the same shape and are all star structures.

An annular protrusion 2 is fixedly arranged under the spreader frame 1. The annular protrusion 2 takes the center of the spreader frame 1 as the center of the circle. The lower surface of the annular protrusion 2 is provided with an annular T-shaped groove 21. The T-shaped groove 21 is connected to the ring The protrusions 2 are concentric, and a plurality of moving sliders 3 are arranged in the T-shaped groove 21, and a certain place of the annular protrusion 2 can be disconnected, and then a plurality of moving sliders 3 are inserted into the T-shaped groove 21, and then the fractured part Solder seal. A connecting block 5 is welded and fixed on the lower surface of each moving slider 3. The connecting block 5 is in the shape of a "concave". The hanging claw 4, the hanging claw 4 is an inverted concave shape, and the edge of the leg inside the hanging claw 4 is welded with a triangular metal sheet as the reinforcement rib 29, and both sides of the hanging claw 4 are provided with bolt mounting holes 41, two bolt mounting holes 41 are symmetrical in position, and all the hanging claws 4 have the same shape. The moving slider 3 and the connecting block 5 can be integrally formed with a material with good tensile strength, and a hole for passing the hanging claw 4 can be processed on the common body of the two. The concave hanging claw 4 can be welded Made of steel.

A groove 22 is respectively processed on both sides of the annular protrusion 2, the groove 22 is annular, and a clamping rod 6 is welded and fixed on both sides of the connecting block 5, and the top of the clamping rod 6 is hooked in the groove 22 in a hook shape. , when the connecting block 5 moves with the moving slider 3, the clamping rod 6 can also move in the groove 22. A reinforcing rib 7 is also welded and fixed between the clamping rod 6 and the connecting block 5 .

When using this type of special spreader to hoist large dry-type air-core reactors, use lifting equipment and hooks to hang the hoisting hole in the middle of the spreader frame 1, and move the spreader frame 1 to the star frame 8 of the large dry-type air-core reactor Directly above, move each hanging claw 4 to the mounting hole 81 of the star frame 8 directly above, and then fix all the hanging claws 4 in the holes of each connecting block 5 to the mounting hole 81 of the star frame 8 by bolts, and then Stable lifting.
