Hydraulic engine powered winch

[0039] Example 1

[0040] like Figure 1-Figure 3 As shown, the hydraulic winch mill includes a gasoline engine 8, a hydraulic variable pump 5, and a drum 1. A gasoline tank 9 is arranged behind the gasoline engine 8 to store gasoline. A coupling 6 is arranged on the gasoline engine 8 to transmit power. The coupling 6- A battery 7 is arranged on the side to provide starting power, a hydraulic variable pump 5 is arranged on the coupling 6 to generate hydraulic pressure, a radiator 11 is arranged on one side of the gasoline engine 8 to increase heat dissipation of the hydraulic oil tank 18, and a hydraulic oil tank is arranged behind the radiator 11 18, containing hydraulic oil, a filter 4 is arranged on the hydraulic oil tank 18 to filter the hydraulic oil, and a relief valve 10 is arranged in front of the radiator 11, and the maximum traction force is limited by adjusting the size, and a ball valve is arranged on the side of the relief valve 10 12. It is used to control the work of the brake 17. A hydraulic handle 13 is arranged on one side of the ball valve 12 to control the maximum traction force. An electric contact hydraulic gauge 14 is arranged above the hydraulic handle 13 to display the load. The side of the filter 4 is provided with a second A quick-change joint 15, the connecting buckle of the power part, a hydraulic motor 3 is arranged on one side of the first quick-change joint 15, and the hydraulic pressure is converted into a mechanical force. One side of the hydraulic motor 3 is provided with a reducer 2, which reduces the speed and increases the torque. The side of the reducer 2 is provided with a drum 1, which is wound with a wire rope. The drum 1 is provided with a brake 17 to control the rotation of the drum 1.

[0041] Example 2

[0042] The difference between this embodiment and embodiment 1 is:

[0043] The coupling 6 is respectively connected with the gasoline engine 8 and the hydraulic variable displacement pump 5 using a flat key, and the flat key connection facilitates the smooth transmission of the power of the gasoline engine 8 to the hydraulic variable displacement pump 5 .

[0044] Working principle: The gasoline engine 8 burns gasoline to generate power, and the power is transmitted to the hydraulic variable pump 5 through the coupling 6, and the hydraulic variable pump 5 converts mechanical energy into hydraulic energy, and then passes through the middle of the first quick-change joint 15 and the second quick-change joint 16 The connected oil pipe transmits the hydraulic energy to the hydraulic motor 3. The hydraulic motor 3 converts the hydraulic energy into mechanical energy and transmits it to the reducer 2. The reducer 2 transmits the mechanical energy to the drum 1 after decelerating and increasing the torque. The drum 1 rotates through the The wire rope realizes the ascent and descent of the heavy object.

[0045] The hydraulic handle 13 moves back and forth to control the displacement of the hydraulic variable pump 5 to realize the speed of the rotating speed of the drum 1; the overflow valve 10 limits the size of the maximum traction force by adjusting the size, and prevents the traction force from being overloaded when heavy objects are added to other forces. The safety of users and equipment; there is an electric shock on the hydraulic gauge at the electric contact point, adjust the pointer to the required position, if the traction force loses control and is too large, it will trigger the pointer, as long as it touches this pointer, the gasoline engine 8 will turn off, ensuring use The safety of the operator and the equipment; the function of the ball valve 12 is to close the ball valve 12 to brake the brake 17 before lifting the heavy object. Moving the hydraulic handle 13 can change the maximum traction force at this time, which is convenient for the operator to understand the maximum traction force at this time.
