Integral oil cylinder base

Abstract

The invention relates to an integral oil cylinder base, which comprises a first oil cylinder seat and a second oil cylinder seat. The integral oil cylinder base is characterized in that: the upper ends of the first and second oil cylinder seats are connected by an upper support plate, while lower ends are connected by a lower support plate; the upper support plate above the first oil cylinder seat is provided with a first hole; the upper support plate above the second oil cylinder seat is provided with a second hole; the first oil cylinder seat and one end of the lower support plate are provided with a third hole and a fourth hole respectively; the second oil cylinder seat and the other end of the lower support plate are provided with a fifth hole and a sixth hole respectively; the third and fourth holes are through holes concentric with the first hole; the fifth and sixth holes are the through holes concentric with the second hole; and a vertical distance between the center of circle of the first hole and the center line of the upper support plate is A, the vertical distance between the center of circle of the second hole and the center line of the upper support plate is B, and A is equal to B. The integral oil cylinder base reduces mounting workload and is convenient for maintenance and positioning.

Description

technical field [0001] The invention relates to an integral oil cylinder base, in particular to an integral oil cylinder base for a swing cylinder hydraulic steering gear oil cylinder. Background technique [0002] The rudder pushing device of the swing cylinder hydraulic steering gear is composed of two hydraulic cylinders of the same type. When installing the rudder pushing device (oil cylinder), when the tiller is at zero position, the cylinder head earrings of the cylinder and the rudder The cylinder bottom earrings are connected with their respective cylinder bases. The four points connected to the cylinders must form an isosceles trapezoid. Since the bases of the two cylinders are separated, it is difficult to ensure the center distance between the bases of the two cylinders during assembly. , increasing the installation workload. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an i...
