Safe, rapid and efficient hoisting device

Abstract

The invention discloses a safe, rapid and efficient hoisting device, and relates to the technical field of hoisting equipment. The hoisting device comprises a transverse plate, wherein a hoisting rodis fixedly arranged on the upper surface of the transverse plate, and a supporting plate is fixedly arranged at the position, close to the top, of the outer surface of the hoisting rod; a first porcelain bushing body is arranged on the lower surface of the supporting plate, the lower surface of the first porcelain bushing body is movably arranged in the middle part of a cylinder, and placement plates are movably placed on the upper surface of the cylinder; a second porcelain bushing body is movably placed on the upper surfaces of the placement plates, an external thread is arranged at the position, close to the top, of the upper surface of the hanging rod, and a pressing mechanism is arranged at the position, close to the lower side, of the external thread; and the pressing mechanism comprises a pressing plate, a threaded hole and a first locking nut, and a threaded hole is formed in the middle part of the pressing plate. The safe, rapid and efficient hoisting device equipment greatlyimproves replacement and maintenance efficiency, can carry out replacement and maintenance in normal production, improves the safety operability of limited-space, high-altitude and high-temperature operation, and also improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a safe, quick and efficient hoisting device. Background technique [0002] As the most important component in the electrostatic precipitator, the insulating porcelain sleeve can provide insulation protection for the cathode, thereby ensuring the normal and stable voltage of the electric field. The electrostatic precipitator porcelain sleeve is used for the high-voltage insulation of the sealed box where the suspending rod of the corona pole suspension frame passes through the field shell, and is divided into three types: straight sleeve, tapered sleeve and special-shaped sleeve. [0003] After a long time of use, the porcelain bushing will be damaged and needs to be replaced. However, when replacing the porcelain bushing, it needs to be operated in a limited space, high altitude, high temperature and needs to stop production. It takes a long time and seriously affects ...
