Description

Mini-split electric lifting device

technical field

The utility model relates to the technical field of electric operation tooling, in particular to a small split type electric lifting device.

Background technique

When the 35kV outdoor current transformer is replaced, the current transformer is generally located behind the switch. The lifting arm of the crane station on the road must pass the switch to lift the transformer. Another example is that when replacing a 35kV bus PT, its installation position cannot be reached by a crane, or the lifting height is affected by the live bus above; there are many similar situations, such as the replacement or installation of a 35kV outdoor switch. Due to site conditions, the scope of power outage was expanded, and lifting equipment could not even be used.

In addition, when replacing the 35kV outdoor voltage transformer, many people need to cooperate to lift the voltage transformer for replacement, which is time-consuming and labor-intensive, difficult to overhaul, and difficult to guarantee personnel safety; moreover, a large crane is required to lift the 35kV outdoor switch blade , The crane is inconvenient to enter and exit, and it is easy to accidentally hit the live bus above, which will expand the power outage area.

And there are following deficiencies in the small lifting device that uses at present:

1. The volume is too large, and it is inconvenient to carry on site;

2. Unable to adapt to the special working environment and lack of flexibility;

Three, the length is too long, it is easy to cause safety hazards in the process of installation and fixing.

Utility model content

The purpose of the utility model is to provide a small split type electric lifting device, which can be assembled and fixed conveniently and quickly at the work site, realizes lifting of electric equipment, is convenient to carry, has high flexibility, and is safe and reliable.

The technical scheme that the utility model solves its technical problem adopts is:

The small split type electric lifting device includes a set of hoops, which are installed on the column of the power work area from top to bottom. Each hoop is connected to a beam. The beam is connected with a vertical lower suspension rod, and the beam of the upper hoop is connected with a vertical upper suspension rod; the lower suspension rod and the upper suspension rod correspond to form a plug fit, and the upper suspension rod is also fixed with a horizontal Suspension arm, there is also a reinforcing rod between the suspension arm and the upper suspension rod; the top of the upper suspension rod is provided with a first pulley, and the outer end of the suspension arm is provided with a second pulley; the hoisting rope of the winch passes through the lower suspension in turn The suspension rod, the upper suspension rod, the first pulley, the suspension arm and the second pulley make the lifting hook hang.

Further, the hoop is a snap connection.

Further, the suspension arm is a telescopic structure.

The beneficial effect of the utility model is that the hoop, the beam, the hoist fixing seat, the hoist, the lower suspension rod and the upper suspension rod are all detachable structures, which can be quickly assembled and fixed when in use, and realize the maintenance of power equipment. It is easy to lift and flexible to use to ensure the safety of operators; it is easy to carry after disassembly and can be used in different work areas.

Detailed ways

As shown in Figures 1 to 3, the utility model provides a small split-type electric lifting device, including a set of hoops, which are installed on the column 1 of the power work area from top to bottom. In this embodiment, three hoops are used. That is, the lower hoop 2a, the middle hoop 2b and the upper hoop 2c; each hoop is connected with a beam correspondingly, that is, the lower beam 3a, the middle beam 3b and the upper beam 3c; the lower beam 3a is connected with a winch fixing seat 4, and the middle The crossbeam 3b is connected with a vertical lower suspension rod 5, and the upper crossbeam 3c is connected with a vertical upper suspension rod 6; the winch fixing seat 4 is provided with a winch 7; The top of the rod 5 is provided with a socket 5a, and the bottom of the upper suspension rod 6 is provided with a plug 5b, and the plug 5b forms an insertion fit with the socket 5a; the upper suspension rod 6 is also fixed with a horizontal suspension arm 8, the suspension arm 8 There is also a reinforcing rod 9 between the upper suspension rod 6, and the suspension arm 8, the upper suspension rod 6 and the reinforcing rod 9 form a triangle; There is a second pulley 11 at the end; the lifting rope 12 of the winch 7 passes through the lower suspension rod 5, the upper suspension rod 6, the first pulley 10, the suspension arm 8 and the second pulley 11 in turn, so that the lifting hook 13 of the winch 7 overhang.

Between each hoop and the crossbeam, between the lower crossbeam 3a and the winch fixed seat 4, between the middle crossbeam 3b and the lower suspension rod 5, and between the upper crossbeam 3c and the upper suspension rod 6, bolts can be used for connection. Preferably, the hoop is a buckle connection, and the suspension arm 8 is a telescopic structure.

When in use, you only need to assemble the device on the column of the power work area that needs to be hoisted, and then hoist it through the hoist 7; the telescopic suspension arm 8 can expand the hoisting range and have wider adaptability; the suspension arm 8. The triangle formed by the upper suspension rod 6 and the reinforcing rod 9 can enhance the stability of the suspension arm; the buckle-type hoop is used to make the fixed installation faster; and the installation height of the hoop can be flexibly adjusted, thereby changing the lifting High height, very flexible in use; easy to carry after disassembly, and can be used in different work areas.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form; any person familiar with the art can use The methods and technical contents disclosed above make many possible changes and modifications to the technical solution of the utility model, or modify them into equivalent embodiments with equivalent changes. Therefore, any simple modifications, equivalent replacements, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention are still protected by the technical solutions of the present invention. within range.
