Description

The invention relates to rigging devices for turning over bulky goods, in particular for mounting and dismounting power transformers.

Closest to the claimed device is a lifting device for bulky goods containing a platform and a traction electric winch with a cable (RU 2184052 C2, June 27, 2012).

The disadvantages of the known device include the lack of ease of control of the device, especially when tilting, mounting and dismounting large devices, such as a power transformer.

The objective of the invention is the creation of a lifting device to facilitate labor and reduce the time for installation / dismantling, for example a power transformer. The invention allows one installer to turn the power transformer into a closed booth and mount it there.

The problem is solved in that the lifting device for bulky goods contains a platform and a towing winch with a cable, and the platform is equipped with retractable support racks having both step and fine height adjustment to move the platform in the vertical direction, for this, these racks are equipped with locking fingers for fixing the platform and supporting screws resting on the supporting heels, traction beam, coupled to the cable, bypass roller, movable beam mounted on the grass Su and ramps installed on the platform axes.

The invention is illustrated in the drawing, where in FIG. 1 shows a lifting device from the side (FIG. 1a) and from above (FIG. 1b), FIG. 2 shows side and top views of a device with a load (transformer), FIG. 3 shows the installation of a transformer, and FIG. 4 - dismantling of the transformer.

The lifting device comprises (Fig. 1) a supporting platform in the form of a platform 1, equipped with retractable support posts 2, which have both step and fine height adjustment to move the platform in the vertical direction. The step-by-step movement of the uprights is fixed by the locking fingers 3 mounted on the platform, and fine adjustment is made by the support screws 4, which are supported by the support heels 5. An auxiliary bypass roller 6 is installed in front of the platform to store the cable for moving the yoke in the ejection direction.

The platform is equipped with ladders 7, which are mounted pivotally on the axes 8 of the platform 1.

Traction beam 9 is attached to the platform. A movable beam 10 is mounted on it as necessary.

The platform is also equipped with a traction electric winch 11.

The procedure for the installation of a transformer in a substation.

The platform is installed horizontally in the open door range of the transformer substation (Fig. 2 and Fig. 3). In this case, the front of the platform 1 rests on the threshold, and the back of the uprights 2 with supporting heels 5 rests on the surface of the earth. The difference in the reference heights is compensated by changing the vertical movement of the uprights 2. When the position of the uprights 2 is changed stepwise, they are fixed with the locking fingers 3, and finer height adjustment is made with the support screws 4 located at the base of the uprights. The range of movement of the platform is with screws.

After the platform is installed, the necessary ladders are installed between it and the substation threshold 7. The ladders are mounted hinged on the axes 8, which makes it possible to compensate not only the height difference between the platform and the substation base, but also the gap formed during installation between the platform and the substation threshold.

Before installing the transformer on the platform 1, the running wheels are mounted on it and only then the transformer is installed by the lifting mechanism. On the transformer base, from its outer side (from the winch side), a traverse beam 9 is installed, with a short end in the direction of the winch 11.

Next, you need to unwind the cable on the winch 11, passing it through the bypass roller 6 mounted on the platform 1, and hook it onto the axis of the traverse beam 9.

When operating the winch 11, it is necessary to move (push) the transformer along the platform 1 to the bypass roller 6. After the transformer stops, the hook must be disconnected from the traverse beam 9 and reinstall it with the long end in the direction of the winch 11.

Then it is necessary to hook the hook to the axis of the traverse beam 9. When operating the winch 11, it is necessary to further move the transformer along platform 1 and further, at the base of the transformer substation, to the installation site of the transformer.

The procedure for dismantling the transformer at the substation.

The transformer canting platform is installed horizontally in the open door range of the transformer substation (Fig. 4). In this case, the front of the platform 1 rests on the threshold, and the back of the uprights 2 with supporting heels 5 rests on the surface of the earth. The position of the racks 2 is fixed by the locking fingers 3. A finer adjustment of the installation height is made by screws 4 located at the base of the racks. The range of movement of the platform is with screws from 0 to 100 mm.

After the platform is installed, the necessary ladders are installed between it and the substation threshold. 7. The ladders are pivotally mounted on the axes 8, which makes it possible to compensate not only the height difference between the platform and the substation base, but also the gap formed during installation between the platform and the substation threshold.

On the transformer base, on its inner side, a traverse beam 9 is installed, with a long end in the direction of the winch 11. A movable beam 10 is installed on the long end of the traverse beam 9, which is pressed against the base of the transformer and rests on the beam of the running wheels. The long end of the traverse beam 9 is supported on weight.

Next, you need to unwind the cable on the winch 11 and hook the hook on the axis of the traverse beam 9.

When operating the winch 11, it is necessary to move the transformer along the base of the transformer substation and drag it onto the platform 1, moving it to the stop limiter. Next, disconnect the hook from the traverse beam 9 and remove it from the transformer.

Next, with a lifting mechanism, you need to remove the transformer from the platform and dismantle the running wheels.
