The apparatus has the advantages of use convenience, large bearing force, high safety coefficient and long service life.

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...

AI Technical Summary

Problems solved by technology

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 general jacking devices are not detachable, so that once the device is partially damaged, it will be damaged. Overall scrapping, a huge waste of material and energy

[0003] The notification number CN204689533U discloses a jacking device, including a column, a spring, a beam, a connecting plate, a hydraulic cylinder, a cylinder support, a jacking upper support plate, a slider, a jacking arm, a guide rail, and the upper end of the column Springs are provided, and the column is in the shape of "匚", and a guide rail is arranged inside the column, and the guide rail is in the shape of "work", and there is a groove at the lower end of the "work", and the upper end of the spring is set A beam, the center position of the bottom surface of the beam is provided with a jacking upper support plate, the jacking upper support plate is connected to the upper end of the jacking arm, and the jacking arm is progressively connected to the slider downward in a scissors-like manner, The two ends of the slider are connected to the guide rail, the protrusions on the slider correspond to the grooves on the guide rail, one end of the slider is connected to the locator, and the left and right ends of the jacking arm are connected to the hydraulic cylinder The upper end of the jacking arm, the hydraulic cylinder, and the connecting plate are connected by a pin, and the lower end of the hydraulic cylinder is connected to the cylinder support on the side of the column and fixed by the cylinder pin. The lifting device is relatively complicated and cannot be disassembled. Once the whole device is partially damaged, it cannot continue to be used; the notification number CN203946850U discloses a hydraulic lifter, which includes a support chassis with rubber wheels at the lower end, and a slideway on the support chassis. There are several pairs of vertically distributed and hinged support rods arranged on the support chassis. The ends of each pair of adjacent support rods are hinged to each other. There is a lift cylinder hinged between one of the upper ends of one of the support rods and the support chassis, one of the lower ends of the bottom pair of support rods is hinged with the support chassis, and the other of the bottom pair of support rods is The lower end is set in the slideway, and a two-speed reversing oil pump connected to it is set on the lifting cylinder, which has a low safety factor, and the load-bearing capacity of the whole device is not enough, and the chassis is not stable enough
