Lightweight special-purposed spreader and mounting method thereof

Abstract

The invention relates to a lightweight special-purposed spreader and a mounting method thereof. The spreader comprises a pedestal, a lower pole, an upper pole, a cross arm, more than one of suspension rings, more than one of collection parts, and more than one of hoops. The lower pole is movably and detachably connected with the pedestal. The upper pole is inserted in the lower pole. The relative position between the upper pole and the lower pole is adjustable. The cross arm is arranged on the upper end of the upper pole. The suspension rings are suspended on the cross pole with certain spaces. One ends of the connection parts are arranged on a device structure, and the other ends are connected on the lower pole. The lightweight special-purposed spreader is safe and reliable, and has the advantages of convenient transportation and simple and convenient operation in device assembly, technical improvement, and maintenance. The spreader is suitable for assembly, technical improvement, and maintenance of various on-rod devices. With the spreader, operation time can be shortened, power-off range can be reduced, working efficiency can be improved, working safety factor can be improved, device power-off frequency can be reduced, device safe and reliable operation can be ensured, and great economic and social benefit can be produced.

Description

technical field [0001] The invention relates to a special spreader, in particular to a portable special spreader and an installation method. [0002] Background technique [0003] With the development of social economy, the demand for electricity is increasing. In order to ensure the social demand, the installation and maintenance work of substation equipment is also increasing. When replacing or overhauling heavy column-mounted equipment such as isolating switches and transformers, etc., Cranes are mainly used for lifting, long preparation time, slow work efficiency, long power outage time, high cost, etc. Second, the use of cranes in substation intervals may cause power outages at adjacent intervals or busbars due to insufficient safety distance. Those equipments to be repaired A large amount of manpower has to be carried on the shoulders during operation, which increases the labor intensity of the operators, prolongs the power outage time, and brings more inconvenience ...

[0003] With the development of social economy, the demand for electricity is increasing. In order to ensure the social demand, the installation and maintenance work of substation equipment is also increasing. When replacing or overhauling heavy column-mounted equipment such as isolating switches and transformers, etc., Cranes are mainly used for lifting, long preparation time, slow work efficiency, long power outage time, high cost, etc. Second, the use of cranes in substation intervals may cause power outages at adjacent intervals or busbars due to insufficient safety distance. Those equipments to be repaired A lot of manpower has to be carried on the shoulders during the operation, which increases the labor intensity of the operators, prolongs the power outage time, and brings more inconvenience to the production or life of the people.
