Abstract

The quick-release clamp is designed for quick connection of high-pressure hoses to linear hydraulic motors and consists of a hollow body of the pressure chamber, in which a piston with an axial hole is slidably arranged and screwed onto the body of the pressure chamber. An adjustable sleeve nut, on which a guide sleeve carrying a clamping strip, which is controlled by a lever mechanism, is slidably mounted, and the sliding guide sleeve, carrying the clamping strip, is slidably mounted on an adjustable sleeve nut, screwed onto the body of the pressure chamber, while the constant size of the volume of the pressure chamber is given by the seating on the piston, which is supported by the front of the body of the pressure chamber, which allows movement and clamping of the clamping strip, using a lever mechanism, without changing the volume of the pressure chamber when clamping the quick-release clamp to the linear hydraulic motor.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quick coupler for supplying a pressurized medium to tested straight-line hydraulic motors using the principle of different surfaces and clamping by means of a clamping belt.

The known quick couplers of this type have a clamping band fixed to the telescoping chamber, or to an extended part of the compartment, placed in a pressure chamber.

The attachment of the clamping belt requires the movement of the piston in the chamber when connecting (quick release coupler to rectilinear hydromotor. Reducing the volume of the chamber helps to eject the hydraulic fluid from the quick coupler. The quick couplers using volume pressure chamber changes require an additional leak prevention device. quick release coupler fluid from primordial hydromotor.

Disadvantages of the hitherto known quick couplers are removed by a quick-acting clamp consisting of a hollow body of the pressure chamber, in which an adjustable sleeve nut is screwed into the hollow body of the pressure chamber with a slidably supported guide sleeve supporting the clamping belt, which is operated by a lever. A mechanism according to the invention, the principle of which is that the sliding guide sleeve carrying the tensioning belt is mounted slidably on the adjustable sleeve nut, screwed onto the housing of the pressure chamber, the piston being fitted with a shoulder, which is supported on the face of the pressure chamber body. The advantage of the solution according to the invention is that the clamping band is mounted on a sliding steering sleeve, which is connected to the adjustable sleeve by means of pull rods and screwed onto the pressure chamber body, which allows the clamping strip to be pushed and moved to the straight line to be tested hydraulic motor, without changing the volume, even without spraying hydraulic fluid from the quick coupler.

The application of the invention enables the quick coupling (disconnection) of the quick coupler to the tested linear hydraulic motor without hydraulic fluid spraying. An exemplary embodiment of a quick coupler is shown schematically in the figure. The quick coupler consists of a hollow telescoping chamber 1, in which a replaceable sealing piston 2 with an axial hole is displaceably mounted. The piston is provided with an upper sealing ring 3 in the upper part and a sealing ring 4 in the lower part. An adjustable socket nut 5 is screwed into the upper part of the pressure chamber 1, on which the guide sleeve 12, which is pulled out, is slid. 9 and pins 8 connected to levers 7 which are rotatably mounted on the second pins (6) in the adjustable sleeve nut 5. The clamping band 11 is attached to the guide sleeve 12 by means of third pins 10 which are pivotally connected to the rods. 9. The mounting on the piston 2 serves as a stop that determines the size of the pressure chamber.

The quick-release feature is as follows:

By moving the levers 7 downwards, the guide sleeve 12 also moves downwardly with the clamping band 11, thereby forming a gap between the piston 2 of the pressure chamber and the clamping band which allows the fastener to be slid onto the inlet opening of the straightener.

By moving the levers 7 in the upward direction, the guide sleeve 7 moves upwardly with the clamping band 11, whereby the quick clamp is clamped to the opening of the linear hydraulic motor which is adjustable by means of a resilient sleeve nut 5 on the housing of the pressure chamber 1 The piston 2 is supported by a shoulder on the body of the pressure chamber 1. A pressure test is carried out in which the piston piston 2 is driven by the pressure of the hydraulic fluid supplied to the rectilinear hydromotor.

Upon completion of the pressure test, the quick coupler is detached from the rectilinear hydromotor by moving the levers 7 downward, thereby. the guide sleeve 12 can also be moved downwards with the clamping lever 11. This creates a gap between the plunger of the pressure chamber and the clamping band, which allows the plunger to be extended from a straightforward hydration.

The sliding guide sleeve 12, which supports the clamping belt 11, is accommodated in an adjustable sleeve nut 5 screwed to the telescoping chamber 1, allowing the clamping belt 11 to be moved and clamped by the lever mechanism without changing the volume. - a straight-line hydraulic motor,
