example 1

[0012] Such as figure 1 , 2 Shown, the present invention is provided with a plunger 2, is connected with vertical pin 1 in the middle part of plunger. A left cylinder body 4 is arranged outside the left side of the plunger 2, and a right cylinder body 5 is arranged outside the right side of the plunger 2.

[0013] A left rear cylinder 6 is fixedly connected in series at the rear end of the left cylinder 4, a left piston rod 8 is fixedly connected to the left end of the plunger 2, and a left piston 9 is fixedly connected to the other end of the left piston rod 8, and the left piston rod 8 is inserted In a through hole 10 provided between the left cylinder 4 and the left rear cylinder 6 , the left piston 9 is arranged in the left rear cylinder 6 . A sealing ring 11 is arranged in the through hole 10 between the left cylinder block 4 and the left rear cylinder block 6 .

[0014] Symmetrically, the rear end of the right cylinder 5 is fixedly connected to the right rear cylinder...

example 2

[0017] The piston cylinder structure of the present invention can be stacked in series. Such as image 3 As shown, a left rear cylinder 6 is connected in series at the rear end of the left cylinder 4, a left piston rod 8 is connected to the left end of the plunger 2, and two groups of left pistons 9, 9' are respectively fixedly connected to the left piston rod 8. , the left piston rod 8 is inserted in the through hole 10 provided between the left cylinder 4 and the left rear cylinder 6, and the two sets of left pistons 9, 9' are fitted in the left rear cylinder 6 correspondingly.

[0018] Symmetrically, a right rear cylinder 7 is also connected to the rear end of the right cylinder 5, and a right piston rod and two groups of right pistons are also provided.

example 3

[0020] The invention can also be used on mechanisms arranged in pairs. Such as Figure 4 , 5 As shown, on the basis of Example 1, there are two plungers 2, 2', and two pin shafts 1, 1' respectively push the sliders 12, 12' to drive a symmetrical tiller 3 to rotate, so that The rudder shaft turns.

Abstract

The invention discloses a steering mechanism of a shifting fork piston type hydraulic steering gear, relating to the technical field of shifting fork piston type hydraulic steering gears for ships. The steering mechanism comprises a tiller, a slide block, a plunger and a vertical pin, wherein two ends of the plunger are respectively provided with a left cylinder body and a right cylinder body; the rear end of the left cylinder body is fixedly connected with a left rear cylinder body; the rear end of the right cylinder body is fixedly connected with a right rear cylinder body; two ends of the plunger are respectively symmetrically and fixedly connected with a left piston rod and a right piston rod; the left piston rod and the right piston rod are respectively fixedly connected with at least one group of pistons; the left piston rod is penetrated in a through hole arranged between the left cylinder body and the left rear cylinder body; the right piston rod is penetrated in a through hole arranged between the right cylinder body and the right rear cylinder body; and each group of pistons are respectively correspondingly distributed in the left rear cylinder body and the right rear cylinder body. By using the steering mechanism, the effect of increasing the amount of oil cylinders for rudders can be achieved, so that the aim of increasing the amount of the oil cylinders for the rudders with very low cost input is achieved, the torque force of the steering gear is doubled, and the installation space of the steering gear is also reduced.

Description

technical field [0001] The invention relates to the technical field of fork piston hydraulic steering gear for ships. Background technique [0002] The hydraulic rudder thrusting mechanism used by the existing ships is the plunger cylinder reciprocating fork thrusting mechanism and the piston cylinder swing cylinder type thrusting mechanism designed by the original 704 Research Institute and Changhang Design Institute. To increase its torque, it is mainly achieved by increasing the bore of the rudder cylinder, the radius of the tiller, and increasing the number of rudder cylinders, which directly leads to an increase in the production cost of the steering gear, and increases the space occupied, which is not conducive to saving production. operating costs. Contents of the invention [0003] The purpose of the present invention is to design a rudder pushing mechanism of a fork piston type hydraulic steering gear with low investment cost and energy saving. [0004] The p...
