Abstract

The utility model relates to a box big cover lifting device. At present, the mainstream method for opening the large cover of the box transformer substation is to employ a crane to lift the large cover and install the large cover in a later period. The method is limited by geographical position, rapidness and flexibility of arrival of the crane and higher cost of departure of the crane, so that a set of simple box-type cover-enlarging hoisting device needs to be arranged to safely, rapidly, flexibly and reliably hoist the box and enlarge the cover. The utility model provides a case becomes big lid hoisting accessory, its constitution includes: the box type transformer substation is characterized by comprising vertical beams (1), cross beams (2), outer beams (3) and hanging beams (4), wherein the tops of the vertical beams are vertically connected with the cross beams, the tops of the two cross beams are respectively connected with the two outer beams and the two hanging beams, the tops of the hanging beams are fixedly connected with pulley assemblies (5), ropes (6) are installed in the pulley assemblies, and one ends of the ropes are connected with hanging rings at the tops of box type transformer substation large covers (7); a reinforcing plate (8) is connected between the vertical beam and the cross beam. The utility model is applied to the field of photovoltaic power stations.

Description

Lifting device for box enlarged cover

Technical Field

The utility model relates to a box big cover lifting device.

Background

At present, domestic combined box-type transformers are used more and more, and the overhaul work of the box-type transformers caused by the use of the combined box-type transformers is increased. Due to the special structure of the box transformer substation, elements such as a fuse, an iron core, a tap and the like are basically arranged in the box transformer substation. When the above-mentioned component failure occurs, the box large lid needs to be lifted and opened for disposal.

The currently mainstream method for opening the large cover of the box transformer substation is to employ a crane to lift the large cover and carry out later-stage reinstallation. The method is limited by geographical position, rapidity and flexibility of arrival of the crane and higher cost of departure of the crane, so a set of simple box-to-box large-cover hoisting device needs to be arranged to realize the purpose of safely, rapidly, flexibly and reliably hoisting the box to form a large cover.

Disclosure of Invention

The utility model aims to provide a lifting device for a large cover of a box.

The above purpose is realized by the following technical scheme:

the utility model provides a case becomes big lid hoisting accessory, its constitution includes: the top of the vertical beam is vertically connected with the cross beam, the tops of the two cross beams are respectively connected with the two outer beams and the two hanging beams, the tops of the hanging beams are fixedly connected with pulley assemblies, ropes are installed in the pulley assemblies, and one end of each rope is connected with a hanging ring at the top of the box variable-size cover; a reinforcing plate is connected between the vertical beam and the transverse beam; and a side plate is vertically connected between the two vertical beams on the same side.

The box becomes big lid hoisting accessory, upright roof beam, the crossbeam, outer beam and the hanging beam constitute the support main part, and adopt square steel structure.

The utility model has the beneficial effects that:

1. when the lifting device is used, the box large cover lifting device is placed above the box transformer substation, then the rope is sleeved on the two pulley assemblies, one end of the rope is fixed on the lifting ring at the top of the box transformer large cover, and the other end of the rope is pulled outwards by a worker, so that the box large cover is lifted.

2. According to the size of the box transformer substation shell, a proper foundation support is manufactured. The bracket is made of high-quality square steel so as to achieve the purposes of firmness, durability and convenient movement. The bracket is mainly welded and is connected by bolts, and the bracket is polished and painted with anticorrosion paint after being manufactured.

3. According to the position of the upper large cover of the box transformer substation, a transverse hanging beam is manufactured above a foundation support, a pulley is installed at a proper position of the hanging beam, and a special hoisting rope is equipped.

4. When the combined box large cover hoisting device is used in a photovoltaic power station, safe and rapid hoisting and re-installation of the combined box large cover can be realized through the combined box large cover hoisting device, and the use cost of a crane is greatly reduced while the working efficiency is improved.
