Abstract
A one-way valve of a two-stage stroke single-push-rod electro-hydraulic pusher is characterized in that a piston cylinder is arranged between a shell and a motor base, a motor is arranged in the motor base, an impeller is fixedly connected to an output shaft of the motor, an oil path from the impeller to the piston cylinder is an oil inlet channel, a one-way valve is connected in series in the oil inlet channel, an oil outlet hole is formed in the side wall of the outlet side of the one-way valve, and the outlet of the one-way valve is connected with an oil inlet hole oil path. The one-way valve can divide the total stroke into two-stage stroke of a working brake stage and a parking brake stage under the matching of the electromagnetic valve and other structures, so that the brake has the functions of quickly applying and removing proper working brake force during the whole operation and generating gradually increased strong parking brake force during parking, and after the lifting process of the push rod is completed, the motor can stop rotating, and the energy-saving effect is achieved.
Description
Technical Field
The invention relates to a double-stage stroke single-push-rod electric hydraulic pusher, in particular to a one-way valve which plays an important role in double-stage stroke function and energy-saving function.
Background
At present, the known single push rod electro-hydraulic thruster structure is that a shell is fixedly connected with a motor base, a piston cylinder is fixedly connected between the shell and a motor, the motor is arranged in the motor base, an impeller is fixedly connected on an output shaft of the motor, a piston in the piston cylinder is fixedly connected with a push rod, and one end of the push rod extends out of the shell. When the motor in the motor base drives the impeller to rotate to pump oil in the piston cylinder, the hydraulic oil pushes the piston to move upwards; when the motor stops rotating, the hydraulic oil loses pressure and returns through the clearance of the impeller, and the piston moves downwards. The movement of the piston drives the push rod to act on the brake frame, so that the brake is released or generates braking force.
However, since the crane used in the open air may be dangerous due to the strong wind, it is required to apply an appropriate operation braking force rapidly during the operation, and it is also required to generate a strong parking braking force which is gradually increased when the crane is parked, and the conventional electric hydraulic thruster does not have such a function. The technical scheme that the two different braking forces are achieved by adopting the combined action of the accessories and the electric hydraulic thruster is adopted, however, the adoption of the accessories can cause the complex structure of equipment and the difficulty in debugging, the fault that the electric hydraulic thruster is not matched with the accessories frequently occurs, so that the accessories are in the same virtual shape, and in addition, the motor always rotates during the working period of the whole crane, so that the energy is not saved.
Disclosure of Invention
In order to provide the electric hydraulic thruster with the functions of quickly applying and releasing proper working braking force and generating gradually increased strong parking braking force when the crane is stopped, the total stroke is required to be divided into a working braking stroke and a parking braking stroke, the electric hydraulic thruster works at a working braking level capable of quickly applying proper working braking force during the normal operation of the crane, and the electric hydraulic thruster works at a parking braking level when the crane is stopped to generate gradually increased strong parking braking force. The invention provides a one-way valve of a two-stage stroke single-push rod electric hydraulic pusher, which can divide the total stroke into two stages of strokes of a working brake stage and a parking brake stage under the coordination of an electromagnetic valve and other structures, so that the brake has the functions of quickly applying and removing proper working brake force in the whole operation period and generating strong parking brake force which is gradually increased when the vehicle is parked, and after the push rod is lifted, a motor can stop rotating, thereby achieving the effect of saving energy.
The technical scheme adopted by the invention for solving the technical problems is as follows: the piston cylinder is arranged between the shell and the motor base, the motor is arranged in the motor base, the impeller is fixedly connected to an output shaft of the motor, an oil path from the impeller to the piston cylinder is an oil inlet channel, a one-way valve is connected in series in the oil inlet channel, an oil outlet hole is formed in the side wall of the outlet side of the one-way valve, and the outlet of the one-way valve is connected with an oil path of the oil inlet hole of the electromagnetic valve through the oil outlet hole.
The invention has the advantages that the one-way valve divides the total stroke of the electric hydraulic pusher into the working brake stage stroke and the parking brake stage stroke under the coordination of other structures, so that the brake has the functions of quickly applying and releasing proper working brake force during the whole operation and generating gradually increased strong parking brake force during parking, and the motor can stop rotating after the lifting process of the push rod is completed, thereby achieving the effect of energy saving.
