It is impossible to install large-scale equipment by manpower. Usually, cranes are used for hoisting, the cost is high, and the scope of power outage is large, which will affect the reliability of power supply and the production and life of residents. Furthermore, during the construction or maintenance of the substation, the space inside the substation is narrow, surrounded by live equipment, affected by the construction environment, some large hoisting tools cannot enter, and it is difficult to hoist and drop when replacing switches, capacitors and other equipment, posing safety hazards .

Utility model content

The technical problem to be solved by the utility model is to provide a special hoist for a substation, which is not affected by the space environment in the substation, meets the construction requirements of the substation, and improves the reliability of power supply.

The pulley block includes a fixed pulley and a movable pulley. The upper parts of the two ends of the cross arm are respectively fixedly connected with the second fixed pulley. The fixed end of the stay rope is fixedly connected with the pulley shaft of the movable pulley. The free end of the stay rope is wound around the pulley block and the second fixed pulley. The lower end of the pulley shaft is fixedly connected with a hook.

The base includes an upper platen and a lower platen parallel to each other, and the upper platen and the lower platen are provided with at least two compression bolts perpendicular to the surface of the upper platen, the compression bolts are arranged through the lower platen, and the bolts pass through One end of the lower pressing plate is matched with a compression nut.

The top of the vertical rod is connected to one end of the cross arm through a pressure bearing, the inner ring of the bearing is sleeved on the top of the vertical rod, and the outer ring of the bearing is in clearance fit with the inner wall of one end of the cross arm.

The axes of the second fixed pulleys at both ends of the cross arm are parallel to each other and perpendicular to the horizontal direction of the cross arm.

The beneficial effects produced by adopting the above-mentioned technical solution are: the utility model includes a base, which is composed of an upper pressing plate and a lower pressing plate parallel to each other, and the upper pressing plate and the lower pressing plate are provided with at least two pressing bolts perpendicular to the upper surface of the upper pressing plate, When in use, put the frame that needs to be replaced between the upper platen and the lower platen, and fix it with the pressing bolts at both ends, which is convenient and reliable to use. The top of the pole is equipped with a cross arm that can rotate horizontally. The pole and one end of the cross arm are connected by a pressure bearing, so that the cross arm can rotate 360° horizontally around the pole. It is flexible and labor-saving, and meets the lifting requirements in all directions. The open end of the cross arm is equipped with a pulley block. The pulley block includes a fixed pulley and a movable pulley. The upper parts of the two ends of the cross arm are also fixedly connected with the second fixed pulley. Using the pulley principle, the construction personnel can easily lift the equipment, saving time and labor. ,Improve work efficiency. The utility model has the advantages of simple structure, convenient use, low cost, safety and reliability, is especially suitable for use in substations with narrow spaces, and has good popularization value.
