Description

Frame quick release small equipment lifter

technical field

The utility model relates to auxiliary equipment in the operation process of electric power equipment, in particular to a quick-installed small equipment lifter with a structure.

Background technique

For a long time, in the technical transformation project of power system transformation equipment, we often encounter work sites where large-scale lifting equipment cannot be used due to the limitation of the working environment, that is, work sites where lifting cranes and arm trucks cannot be used, such as 220kV knife gates , 110kV knife switch, 35kV knife switch, current transformer, outdoor 10kV capacitor switch switch and other equipment are densely arranged, and the construction site where the safety distance of large lifting equipment is insufficient. The existing working method is: use a lot of labor to dismantle it from the equipment structure, and then move it away by manpower. There is no suitable lifting equipment on site, which not only has potential safety hazards, but also easily damages the disassembled equipment.

Its disadvantages are: (1) The labor intensity is high, and the on-site operation is not standardized. (2) A large amount of labor is used to disassemble from the high-level structure, which has potential safety hazards. (3) If you want to use lifting equipment, first, you need to expand the scope of power outages, causing unnecessary power outages, and causing losses to the power grid; second, using lifting equipment to replace small equipment is somewhat "overkill".

Contents of the invention

The technical problem solved by the utility model is the lifting of small-sized equipment in the technical transformation project of power system substation equipment.

The utility model is realized by adopting the following technical solutions:

A frame quick-installed small equipment lifter, including a base fixedly installed on the power equipment structure, a column is fixedly installed on the base, a rotating rod is movably fitted on the top of the column, and the rotating rod is fixedly supported by The rotating seat is fixedly connected with a first-stage arm for lifting heavy objects, a second-stage arm is movable in the first-stage arm, fixed pulleys are installed at the end of the second-stage arm, and the first-stage arm A small motor is fixedly installed on the outer wall of the motor, and the output shaft of the motor drives the drum to rotate, and a suspension rope is wound on the drum, and the suspension hook is connected after the suspension rope goes around the fixed pulley.

During work, in the power system substation equipment technical transformation project, the work site where large-scale hoisting equipment cannot be used due to the limitation of the work environment, that is, the work site where lifting cranes and bucket trucks cannot be used, firstly use the lifting device of the present invention The base is firmly fixed on the power equipment structure. Since the top of the column is equipped with a rotating rod, the rotating base is rotated to adjust the lifting position, and the lifting hook is lifted or lowered by controlling the motor to achieve the purpose of lifting the equipment. At the same time, adjust the horizontal distance of lifting by adjusting the position where the secondary arm extends out of the primary arm.

The utility model has a reasonable design. By developing a small lifting device that can be fixedly installed on the power equipment structure (referring to the power equipment structure welded by 8-16cm channel steel), the lifting weight is ≦200kg, which can ensure the on-site operation. It saves manpower and improves work efficiency, and the construction site is neat and orderly, so as to achieve the goal of good lifting effect and civilized work site.

Detailed ways

Specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

A frame quick-installed small equipment lifter, as shown in Figure 1, includes a base 3 fixedly installed on the power equipment frame 4, a column 5 is fixedly installed on the base 3, and the top of the column 5 is movable There is a rotating rod 14, and the rotating rod 14 is fixedly supported with a rotating seat 6, and the rotating seat 6 is fixedly connected with a primary arm 7 for lifting heavy objects, and a secondary arm 8 is movable in the primary arm 7, A fixed pulley 13 is installed on the end of the secondary arm 8, and a small motor 9 is fixedly installed on the outer wall of the primary arm 7. The output shaft of the motor 9 drives the drum 12 to rotate, and the drum 12 is wound with a suspension. The rope 10 is connected with the hook 11 after the suspension rope 10 goes around the fixed pulley 13.

During specific implementation, the four corners of the base 3 are respectively fixedly connected to two parallel fixing plates 2 by bolts, and the fixing plates 2 are fixedly installed on the power equipment frame 4 through the fixing fixture 1 .

A number of reinforcing plates are welded at the connection between the column 5 and the base 3 to further increase the stability of the jack.

The primary arm 7 and the secondary arm 8 can be positioned by positioning pins to ensure that the secondary arm will not suddenly retract into the primary arm during the lifting process, which will affect the smooth progress of the lifting.

The column 5 shown has a height of 1 m and the primary arm 7 has a length of 1 m.
