Description

A portable loading and unloading rack

technical field

The utility model relates to a portable loading and unloading rack, which is suitable for hoisting of electrical equipment.

Background technique

In the power transmission and transformation equipment, the equipment intervals of the 35kV outdoor substation are relatively dense. In the prior art, when such equipment is repaired and replaced in the station, it is necessary to use a crane to disassemble and assemble. For example, in the replacement construction of a 10kV vacuum switch, the equipment is located on a suspended structure. Due to the large size of the crane, at least one section of the 10kV busbar must be powered off to ensure safe operation. In order to ensure the safety of the peripheral equipment of the crane, more safety protection measures should be taken. If manual disassembly is required, it is necessary to excavate the ground to bury sand poles, hang pulleys, and drag with large ropes. The power outage area is relatively large, and the operation is complicated, requiring the cooperation of multiple people, and the working time is prolonged. This type of maintenance work requires large-scale power outages in the station, many safety measures, high risk factors, and complicated operations. From the perspective of economic benefits, too long power outage time will inevitably increase the economic loss of the power grid.

Utility model content

The technical problem to be solved by the utility model is to provide a portable loading and unloading rack which is simple in structure, easy to use and can be installed on a suspended frame.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a portable loading and unloading rack, which is characterized in that it includes a base, a column, a triangle frame and a hanging chain; the lower end of the column is vertically fixedly connected with the base, and the column The upper end is connected with the triangular frame; the hanging chain is hung on the triangular frame.

The further improvement of the utility model is: it also includes a cylinder connected to the upper end of the column; the vertical side of the triangular frame is a rotating shaft, and the lower end of the rotating shaft is connected to the cylinder through a bearing. The triangular frame is provided with a hanging ring, and the hanging chain is connected with the hanging ring; the base is a channel steel connected to the lower end of the column, and the channel steel is provided with bolt connection holes.

The beneficial effects of adopting the above technical scheme are: the safety factor of personnel and equipment in the maintenance work is improved, the power outage area of the work site is reduced, and it can replace large cranes for high-altitude hoisting equipment, which facilitates the maintenance and replacement of equipment and improves the power supply. Quality, shorten power outage time, save costs and improve labor efficiency.

Description of drawings

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

Fig. 1 is the structural representation of the utility model.

As shown in the figure: 1 column, 2 lifting rings, 3 cylinders, 4 rotating shafts, 5 triangular frames, 6 hanging rings, 7 hanging chains, 8 bases, and 9 high-voltage switch suspension frames.

Detailed ways

Referring to Fig. 1, the operation and use steps of the present utility model are further described: a portable loading and unloading rack, which is characterized in that: it includes a base 8, a column 1, a triangular frame 5 and a suspension chain 7; the lower end of the column 1 is vertically fixedly connected to the base 8 , the upper end of the column 1 is connected with the triangular frame 5; the hanging chain 7 is hung on the triangular frame 5. It also includes a cylinder 3 connected to the upper end of the column 1; the vertical side of the triangular frame 5 is a rotating shaft 4, and the lower end of the rotating shaft 4 is connected with the cylinder 3 through a bearing. The triangular frame 5 is provided with a hanging ring 6, and the hanging chain 7 is connected with the hanging ring 6; the base 8 is a channel steel connected to the lower end of the column 1, and the channel steel is provided with a bolt connection hole. The column 1 is made of I-beam with a height of 1.8m and a width of 0.1m, the base 8 is welded by two channel steels with a width of 100mm, the column 1 and the base 8 . Cylinder 3 is welded on the upper end of column 1, and triangular frame 5 is welded by the steel pipe of diameter 60mm, and the lower end of rotating shaft 4 is connected with cylinder 3 by bearing, and rotating shaft 4 can rotate in cylinder 3. Before the construction begins, the utility model is first raised and placed on the high-voltage switch suspension frame 9, and the bolts pass through the bolt connection holes on the base 8 to fix the high-voltage switch suspension frame 9; The pile is connected firmly; Once again, the hanging chain 7 is hung on the hanging ring 6. The old equipment that needs to be dismantled is hoisted by the hoisting chain 7, and the equipment is safely disassembled to the ground through rotation and alignment with the bottom surface. This overhaul work is operated by two people, can finish hoisting work by hanging chain 7. the
