Abstract

The invention discloses a jacking device, relates to the field of electric power system equipment, and provides a device which is convenient to transport, and small in site requirements, and can lift a holding rod in a mechanical manner. According to the technical scheme, the jacking device comprises a supporting frame, a holding rod frame and a power device, wherein a first channel is arranged in the supporting frame, and an opening of the first channel is formed in the top part of the supporting frame; a fixing part which is fixedly connected to the ground is arranged at the bottom part of the supporting frame; the holding rod frame comprises a fixed section and an extending section; the fixed section is stored in the first channel, and the extending section passes through the opening to extend to the outer part of the first channel; the holding rod frame moves in the axial direction of the first channel; the power device, comprising a motorized winch and a transmission mechanism, is arranged on the supporting frame; one end of the transmission mechanism is connected to the motorized winch while the other end of the transmission mechanism is connected to the holding rod frame; the motorized winch is used for driving the holding rod frame to move in the axial direction of the first channel through the transmission mechanism. The jacking device is mainly used for lifting the holding rod.

Description

technical field [0001] The invention relates to the field of power system equipment, in particular to a jacking device. Background technique [0002] In engineering, large parts are often used. However, the transportation and installation of large parts require a lot of manpower, especially in the construction process of transmission line towers. The towers are high, heavy, and bulky. Standing on the ground, poles are usually used to assemble the tower. However, with the advancement of science and technology, the height of the iron tower has increased, and the height of the pole has increased accordingly, and the safe assembly of the pole itself has become a difficult problem in construction. [0003] In the prior art, the stand-up method of the floor-standing pole mainly relies on the hydraulic jacking device at the bottom of the pole. According to Pascal's principle, after any point in an incompressible static fluid is subjected to an external force to generate a pressure...
