Description

A lightweight lifting frame

technical field

The utility model relates to a lifting frame, in particular to a portable lifting frame with small volume and light weight. the

Background technique

In the maintenance work of outdoor substations, it is often necessary to lift small equipment of about 150 kg. This kind of equipment is heavy and difficult to carry manually. Sometimes it can only be hoisted by a crane. And the working radius of the crane is very large, in order to ensure safety, all the wires in the reach of the crane must be powered off to work, which makes the power outage area larger and the scope of influence wider. Also do not have suitable equipment at present to be used for hoisting above-mentioned small equipment. the

Utility model content

The purpose of the utility model is to provide a portable lifting frame, which is simple in structure and small in size, and can complete the lifting work of small equipment with manpower, greatly reducing the power failure area. the

In order to achieve the above object, the utility model takes the following technical solutions:

A portable lifting frame, comprising a column, characterized in that the bottom of the column is fixedly connected to the base, the side plate is detachably connected to the top of the column, the side plate is fixedly connected to the beam, and a suspension ring is fixed at one end of the beam, and the beam is connected to the side A first reinforcing rib is connected obliquely between the boards, and a second reinforcing rib is connected obliquely between the base and the column.

The base is composed of a first channel steel and a second channel steel, the first channel steel and the second channel steel are respectively welded on both sides of the column, the first channel steel or the second channel steel and the column are inclined The second reinforcing rib is connected to the direction. the

The side plates are connected to the columns via bolts. the

The column is made of channel steel. the

The first channel steel and the second channel steel are provided with through holes, and the first channel steel and the second channel steel are connected to the third channel steel and the fourth channel steel through the through holes through the bolts. the

In the above technical solution, the lifting frame is simple in structure and small in size, and can be fixed on the channel steel of the substation equipment through the first and second channel steels and the third and fourth channel steels, and then hang the movable pulley or the fixed pulley through the lifting ring, and then Small and medium-sized equipment through manpower, easy to use, save time and effort. the

Detailed ways

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

As shown in Figures 1 and 2, the column 1 is generally made of channel steel or other steel materials, and a side plate 5 is installed on the top of the column 1 through screws 6 . The crossbeam 2 is fixedly connected with the side plate 5 and connected obliquely through the first reinforcing rib 4 . One end of the beam 2 is fixedly welded with a suspension ring 3 . The lower end of the column 1 is connected to the base, the base is composed of the first channel steel 10 and the second channel steel 11, the first channel steel 10 and the second channel steel 11 are respectively welded on both sides of the column 1 (as shown in Figure 2), the second The second reinforcing rib 7 is fixedly connected with the first channel steel 10 and the column 1 (the second reinforcing rib 7 can also be fixedly connected with the second channel steel 11 and the column 1). Leave through hole 8 and through hole 9 on the first channel steel 10, leave through hole 20 and through hole 21 on the second channel steel 11.

In use, there are channel steel 15 and channel steel 16 on the equipment of the substation (the cross section of the two is shown in Fig. 3), and the first channel steel 10 and the second channel steel 11 are vertically contacted with the channel steel 15 and the channel steel 16, Add the 3rd channel steel 12 and the 4th channel steel (not drawing among the figure) below. Use a screw to pass through the through hole 9 and the through hole 13, and use another screw to pass through the through hole 8 and the through hole 14 for fastening, then the first channel steel 1 and the third channel steel 12 tightly hug the channel steel 15 and the channel steel 16 In the same way, connect the second channel steel 11 and the fourth channel steel to hold the channel steel 15 and the channel steel 16 with screws, so that the lifting frame can be installed and fixed on the substation equipment. Then hang the movable pulley or the fixed pulley on the suspension ring 3 to lift small equipment, and the operation is simple and convenient. the

This embodiment is only an illustration of the concept and realization of the utility model, and does not limit it. Under the concept of the utility model, technical solutions without substantial transformation are still within the scope of protection. the
