Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, double acting hydraulic cylinder, including cylinder body 1 slidably connect symmetrically arranged first sealing in cylinder body 1
11 are enclosed, is fixedly welded with link block 9 between two the first sealing rings 11, the top of the first sealing ring 11 is fixedly welded with work
Cylinder 6 slidably connects the second sealing ring 8 in seating nipple 6, and the top of the second sealing ring 8 has been bolted to connection work column
5, the upper side of cylinder body 1, which is provided with, moves back oilhole 12, and cylinder body 1 is provided with comprehensive hole 7, cylinder body 1 far from the side for moving back oilhole 12
Lower section be provided with fuel feed hole 10, the two sides in comprehensive hole 7 are symmetrically arranged with electromagnet 14, and electromagnet 14 is equidistantly embedded in cylinder body
In 1, the side of electromagnet 14 is fixedly connected with second spring 13, and the other side of second spring 13 is fixedly connected with sliding block 15,
The top of work column 5 and seating nipple 6 has been fixedly attached spacing collar 4, and the lower section of spacing collar 4 is fixedly connected with the first spring 3, cylinder
