The first oil cylinder 1 is provided with a first piston rod 12 extending out of one end of a cylinder body of the first oil cylinder, the first piston rod 12 is used for being connected with a supporting plate 42 of a four-way vehicle and realizing lifting action of the supporting plate 42, the second oil cylinder 2 is provided with a second piston rod 22 extending out of one end of the cylinder body of the second oil cylinder, and the second piston rod 22 is used for being connected with a reversing device of the four-way vehicle and realizing vertical switching of the driving direction of the four-way vehicle by driving the reversing device to lift.
In some embodiments, the first piston rod 12 of the first cylinder 1 and the second piston rod 22 of the second cylinder 2 extend in opposite directions, and the cylinder body of the first cylinder 1 and the cylinder body of the second cylinder 2 are arranged in a staggered manner to reduce the overall height thereof.
The first oil cylinder 1 and the second oil cylinder 2 are arranged in parallel, and compared with a single oil cylinder installation mode, the dislocation oil cylinder has the advantages that the installation space is reduced, and the dislocation oil cylinder is suitable for scenes which need two hydraulic cylinders to work independently and have opposite operation target directions, such as lifting of a supporting plate 42 at the top of a four-way vehicle and lifting of a running mechanism at the bottom.
In some embodiments, the cylinder body of the first oil cylinder 1 and the cylinder body of the second oil cylinder 2 are an integrated cylinder body or fixedly connected. For example, the first cylinder block 11 and the second cylinder block 21 may be integrally cast or manufactured separately and welded together at a later stage.
In some embodiments, the first cylinder 1 and the second cylinder 2 are arranged in a staggered manner, so that the extending end face of the first piston rod of the first cylinder 1 is staggered with the end face of the second cylinder 2 opposite to the extending end face of the second piston rod 22, and the extending end face of the second piston rod 22 of the second cylinder 2 is also staggered with the end face of the first cylinder 1 opposite to the extending end face of the first piston rod 12. This dislocation hydro-cylinder carries out the dislocation design with two pneumatic cylinders for the whole height is minimum relatively, for the mode of the single installation of pneumatic cylinder, can make its installation need the space further to reduce, improves space utilization.
In some embodiments, the first cylinder 1 and the second cylinder 2 may be the same size. For example, the cylinder bodies of the first cylinder 1 and the second cylinder 2 are rectangular bodies having an equal size.
In some embodiments, the first cylinder 1 and the second cylinder 2 may be both single-rod piston type hydraulic cylinders, and adopt a cylinder fixing mode. The first oil cylinder 1 and the second oil cylinder 2 can be double-acting hydraulic cylinders, and the movement of the piston in two directions is completed by alternately feeding oil through the two cavities and relying on the action of hydraulic pressure.
In some embodiments, as shown in fig. 2, the misalignment cylinder further includes a valve block 3 disposed on one side of the misalignment cylinder, which is a common side of the first cylinder 1 and the second cylinder 2, the valve block 3 having an oil passage inlet 31 and a first oil inlet flow passage 32 and a second oil inlet flow passage 33 communicated with the oil passage inlet 31; the valve block 3 is provided with a first control valve 34 for controlling the opening and closing state of the first oil inlet flow passage 32 and a second control valve 35 for controlling the opening and closing state of the second oil inlet flow passage 33. The control valve may be a solenoid valve, for example.
In an embodiment, the valve block 3 may only integrate the oil inlet passages of the two cylinders of the dislocated cylinder, and the oil outlet passages may not be integrated. For example, the first cylinder 1 includes a first cylinder oil outlet 14 and a first cylinder oil inlet 13 communicated with the first oil inlet flow passage 32, and the second cylinder 2 includes a second cylinder oil outlet 24 and a second cylinder oil inlet 23 communicated with the second oil inlet flow passage 33. The first oil cylinder oil outlet 14 and the second oil cylinder oil outlet 24 are arranged on the side face where the valve block 3 is installed, so that oil paths are all arranged on the same side, space is reasonably utilized, and bending leakage of the oil paths is avoided.
In another embodiment, the valve block 3 can integrate the oil inlet channels and the oil outlet channels of two cylinders of the staggered cylinders at the same time. For example, the valve block 3 has a main oil inlet 31, a main oil outlet, a first oil inlet flow passage 32 and a second oil inlet flow passage 33 communicating with the main oil inlet 31, and a first oil outlet flow passage and a second oil outlet flow passage communicating with the main oil outlet.
