Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic motors, and in particular to a hydraulic device integrating the functions of a hydraulic motor and a hydraulic brake. Background Art

[0002] Hydraulic motors and hydraulic brakes are common equipment in industry. In traditional terminal hydraulic systems, two independent oil circuits need to be designed to control the hydraulic motor and hydraulic brake respectively. The structure is complex, requires a lot of space, is inconvenient for subsequent maintenance, and has high operating costs. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a hydraulic device that integrates the functions of a hydraulic motor and a hydraulic brake, which can simplify the oil circuit design, facilitate maintenance, and reduce the cost of use.

[0004] The technical solution is as follows: a hydraulic device integrating the functions of a hydraulic motor and a hydraulic brake, comprising a hydraulic brake and a hydraulic motor, wherein the hydraulic motor is provided with a forward oil port and a reverse oil port, and the forward oil port and the reverse oil port are connected through an internal oil channel, and is characterized in that the hydraulic brake and the hydraulic motor are connected as one, a shuttle valve mounting hole is provided on the housing of the hydraulic motor, the shuttle valve mounting hole is connected to the internal oil channel, a shuttle valve is installed in the shuttle valve mounting hole, and the shuttle valve is connected to the oil port of the hydraulic brake through a hydraulic oil pipe.

[0005] It is further characterized in that the shuttle valve is threadedly connected to the shuttle valve mounting hole; The shuttle valve mounting hole and the oil port of the hydraulic brake are opened on the same side; The shuttle valve and the oil port of the hydraulic brake are both equipped with hydraulic pipe joints.

[0006] After adopting the present invention, a shuttle valve mounting hole is opened on the housing of the hydraulic motor and a shuttle valve is installed. The hydraulic oil for controlling the hydraulic brake can be directly diverted from the hydraulic oil in the hydraulic motor and flow into the hydraulic oil pipe, thereby controlling the hydraulic brake. This simplifies the oil circuit design, facilitates later maintenance, and reduces the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a schematic diagram of the structure of the present invention; Figure 2 It is a schematic diagram of the shuttle valve assembly of the present invention. DETAILED DESCRIPTION

[0008] See Figure 1 , Figure 2As shown, a hydraulic device integrating the functions of a hydraulic motor and a hydraulic brake includes a hydraulic brake 1 and a hydraulic motor 2. A forward oil port 3 and a reverse oil port 4 are provided on the hydraulic motor 2. The forward oil port 3 and the reverse oil port 4 are connected through an internal oil channel. When the hydraulic oil enters from the forward oil port 3 and flows out from the reverse oil port 4 through the internal oil channel, the hydraulic oil flow drives the hydraulic motor to rotate forward. When the hydraulic oil enters from the reverse oil port 4 and flows out from the forward oil port 3 through the internal oil channel, the hydraulic oil flow drives the hydraulic motor to rotate reversely.

[0009] The hydraulic brake 1 and the hydraulic motor 2 are connected into one by bolts, etc. The output shaft of the hydraulic motor 2 passes through the hydraulic brake 1. A shuttle valve mounting hole 5 is provided on the housing of the hydraulic motor 2. The shuttle valve mounting hole 5 is connected to the internal oil channel. A shuttle valve 6 is installed in the shuttle valve mounting hole 5. A threaded connection is adopted, which is convenient for installation and disassembly. The shuttle valve 6 is connected to the oil port of the hydraulic brake 1 through a hydraulic oil pipe 7. In order to simplify the installation, the shuttle valve mounting hole 5 and the oil port of the hydraulic brake 1 are opened on the same side. The connection can be completed by using a U-shaped oil pipe with two hydraulic pipe joints 8.

[0010] When the hydraulic motor 2 is not working, the hydraulic brake 1 does not take in oil, and the shuttle valve 6 is closed. When the hydraulic motor 2 is to rotate forward, the hydraulic oil enters from the forward oil port 3, flows through the internal oil channel, and finally leaves from the reverse oil port 4. At the same time, the shuttle valve 6 opens, and part of the hydraulic oil passes through the shuttle valve 6 and then enters the hydraulic brake 1 through the hydraulic oil pipe 7, controlling the movement of the piston inside it, releasing the brake, and the hydraulic motor 2 works smoothly; when the hydraulic motor 2 is to reverse, the hydraulic oil enters from the reverse oil port 4, flows through the internal oil channel, and finally leaves from the forward oil port 3. At the same time, the shuttle valve 6 opens, and part of the hydraulic oil passes through the shuttle valve 6 and then enters the hydraulic brake 1 through the hydraulic oil pipe 7, controlling the movement of the piston inside it, releasing the brake, and the hydraulic motor 2 works smoothly; when the hydraulic oil stops supplying, the hydraulic brake 1 is no longer under the pressure of the hydraulic oil, the piston resets, braking the hydraulic motor 2, and the hydraulic motor 2 stops working.
