Description

technical field

[0001] The invention relates to the technical field of machinery, in particular to a special jacking device for changing reactor support porcelain bottles. Background technique

[0002] In the process of electric power construction, due to construction requirements, sometimes it is necessary to lift the electric power equipment. However, power equipment is not a small object, and it is difficult to lift it up, and it requires the use of professional construction tools, that is, jacking devices. The working principle of the jacking device is: place the jacking device under the object to be lifted, use hydraulic pressure to raise the jacking device, and lift the building under the action of the supporting force. Traditional jacking devices generally have supporting plates, but most of the supporting plates are smooth, so that the device is easy to slip when placing objects, and the general jacking devices are not detachable, so that once the device is partiall...
