Technical Field
The utility model relates to a flange formula hydraulic coupling and hydraulic cylinder's composite set belongs to hydraulic coupling technical field.
Background
Normally, a flange-type hydraulic coupler and a hydraulic oil cylinder are two independent structures as a propeller with adjustable pitch and are arranged at different positions, the flange-type hydraulic coupler is arranged at the front end of a stern shaft and connected with an output shaft of a gear box, and the hydraulic oil cylinder is combined with a propeller hub. The hydraulic oil cylinder is soaked in water, once the high-pressure oil leakage occurs to the oil cylinder, the environment is polluted, the docking repair is also needed, the maintenance cost is high, and the repair time is prolonged.
Disclosure of Invention
An object of the utility model is to overcome the not enough of prior art existence, and provide a compact structure, convenient to use, reliable need not the integrated configuration of flange formula hydraulic coupling and hydraulic cylinder of maintenance of docking.
The utility model aims to solve the technical scheme that the combined device of the flange type hydraulic coupler and the hydraulic oil cylinder mainly comprises a piston, a sealing ring, a blind screw, an inner sleeve, an outer sleeve, a support, an oil cylinder piston and a cylinder cover; one end of the outer sleeve is provided with a piston area, the opening of the piston area is provided with a piston, and the inner side of the piston is provided with a sealing ring; the oil cylinder is characterized in that an oil groove is formed in the inner surface of the outer sleeve, an oil filling hole is formed in the inner surface of the outer sleeve and is communicated with the piston area and the oil groove respectively, the inner surface of the outer sleeve and the outer surface of the inner sleeve are conical surfaces matched with each other, the oil filling hole is sealed by a blind screw, a support is mounted on the right side of an inner hole of the outer sleeve through a screw, and a hydraulic oil cylinder is formed between the support and the outer sleeve and.
Preferably, the method comprises the following steps: an oil cylinder piston in the hydraulic oil cylinder and a piston rod are of an integral structure, one end of the piston rod is connected with a guide frame in a push-pull rod type propeller hub of the propeller with the adjustable pitch, the oil cylinder piston horizontally moves under the action of hydraulic oil and drives the piston rod to drive the guide frame to move, and finally a crank mechanism in the propeller hub is driven to enable the propeller blades to rotate forwards and reversely.
The utility model has the characteristics of compact structure, convenient to use, reliable need not the maintenance of docking etc.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings: fig. 1 shows that the combined device of a flange-type hydraulic coupler and a hydraulic cylinder of the present invention mainly comprises a piston 1, a sealing ring 2, a blind screw 3, an inner sleeve 4, an outer sleeve 5, a support 6, a cylinder piston 7 and a cylinder cover 8; the device is characterized in that one end of the outer sleeve 5 is provided with a piston area, the opening part of the piston area is provided with a piston 1, and the inner side of the piston 1 is provided with a sealing ring 2; the improved propeller comprises an outer sleeve 5 and is characterized in that an oil groove is formed in the inner surface of the outer sleeve 5, an oil filling hole is formed in the inner surface of the outer sleeve 5 and is communicated with a piston area and the oil groove respectively, the inner surface of the outer sleeve 5 and the outer surface of an inner sleeve 4 are conical surfaces which are matched with each other, the oil filling hole is sealed by a blind screw 3, a support 6 is mounted on the right side of an inner hole of the outer sleeve 5 through screws, a hydraulic oil cylinder is formed between the support 6 and the outer sleeve 5 and a cylinder cover 8, an oil cylinder piston 7 and a piston rod in the hydraulic oil cylinder are of an integral structure, one end of the piston rod is connected with a guide frame in a push-pull rod type propeller hub with an adjustable pitch, the oil cylinder piston 7 moves horizontally under the action.
The inner peripheral surface of an outer sleeve 5 and the outer peripheral surface of an inner sleeve 4 are correspondingly matched with each other in a certain taper, when the hydraulic coupling is installed, the outer sleeve 5 is expanded by means of radial and axial oil pressure, the outer sleeve 5 slides towards one side with the larger diameter of the inner sleeve 4 along the joint taper surface of the inner sleeve 4 to force the inner sleeve 4 to contract, when the movement displacement of the outer sleeve 5 reaches the designed amount, high-pressure oil is discharged, so that the outer sleeve 5 tightly presses the inner sleeve 4, the inner sleeve 4 tightly presses a hollow transmission shaft, and torque is transmitted by using friction force among the outer.
Example (b): the utility model mainly comprises a piston 1, a sealing ring 2, a blind screw 3, an inner sleeve 4, an outer sleeve 5, a support 6, an oil cylinder piston 7 and a cylinder cover 8; the inner surface of the outer sleeve 5 and the outer surface of the inner sleeve 4 are conical surfaces which are matched with each other, one end of the outer sleeve 5 is provided with a piston area, the opening part of the piston area is provided with a piston 1, and the inner side of the piston 1 is provided with a sealing ring 2; an oil groove is formed in the inner surface of the outer sleeve 5, an oil filling hole is formed in the inner surface and is communicated with the piston area and the oil groove respectively, and the oil filling hole is sealed by a blind screw 3 after the coupler is installed. When oil is fed to the left side of a piston of the hydraulic oil cylinder, the piston pushes a push-pull rod type propeller hub guide frame to move forwards, so that the propeller blade rotates forwards, and the ship moves forwards.
