Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a high-thrust impeller cylinder. Background Technology

[0002] A hydraulic cylinder is a mechanical device used to generate linear motion. It generates force and motion by utilizing the flow of a fluid (usually hydraulic oil). A hydraulic cylinder typically consists of a cylindrical housing, a push rod (or piston), and pipes connected to the hydraulic system.

[0003] Traditional hydraulic cylinders use a direct hydraulic oil push method, which directly pushes the piston to move linearly along the inside of the cylinder, thereby driving the output rod to move linearly. This method is not very smooth or efficient in terms of force distribution during operation, and the maximum thrust obtained is relatively small. Utility Model Content

[0004] The main purpose of this invention is to provide a high-thrust impeller cylinder that uses hydraulic pressure to drive the rotating parts to rotate, which in turn drives the piston rod to rise, thereby improving the stability and efficiency of the cylinder during operation and providing stronger thrust.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-thrust impeller cylinder includes a cylinder body and a cylinder body top cover. The top cover is connected to the top of the cylinder body by screws. An oil chamber is formed inside the cylinder body. An upper threaded plug and a lower threaded plug are respectively fixed to the inner wall of the oil chamber near the top and bottom ends by threads. A rotating piston rod is fitted inside the lower threaded plug and the upper threaded plug. Blades are provided at both ends of the rotating piston rod. A hexagonal positioning head is provided at the top of the rotating piston rod. A push rod piston rod is provided inside the cylinder body top cover near the top end. A rotating base is provided at the lower end of the push rod piston rod. A hexagonal positioning groove is formed at the bottom of the rotating base. The hexagonal positioning groove is fitted outside the hexagonal positioning head. Group B oil inlet and outlet ports are formed at one end of the bottom and outer wall of the cylinder body, and Group A oil inlet and outlet ports are formed at the other end of the bottom and outer wall of the cylinder body.

[0007] Furthermore, an anti-rotation block is provided at the top of the cylinder cover near the edge, and an anti-rotation groove is provided at the top of the piston rod near the edge, with the anti-rotation block being engaged in the anti-rotation groove.

[0008] Furthermore, both the A-group oil inlet / outlet and the B-group oil inlet / outlet are connected to the oil cavity. When oil enters through the A-group oil inlet / outlet, it pushes the rotating piston rod and blade to rotate in the forward direction within the oil cavity. When oil enters through the B-group oil inlet / outlet, it pushes the rotating piston rod and blade to rotate in the reverse direction within the oil cavity.

[0009] Furthermore, a spring-loaded pad is provided at the top of the cylinder top cover near the inner side of the anti-rotation block, and the bottom of the spring-loaded pad contacts the top disc end face of the push rod piston rod.

[0010] Furthermore, the push rod piston rod and the rotating base are provided with contact surfaces near each other. Both sets of contact surfaces are provided with arc-shaped bosses near the central axis, and the contact surfaces extend from the arc-shaped bosses to the edges with two sets of inclined surfaces. When the two sets of contact surfaces rotate to the fit state, it is the retracted state of the push rod piston rod being lifted. When the two sets of contact surfaces rotate to the position of the arc-shaped bosses and contact each other, it is the highest state of the push rod piston rod being lifted.

[0011] Furthermore, the lower threaded plug and the upper threaded plug are both provided with mounting force holes at locations far apart from each other.

[0012] Furthermore, the inner walls of the upper and lower threaded plugs are provided with a second piston oil seal through the mounting groove, and the second piston oil seal is sleeved on the outer wall of the rotating piston rod.

[0013] Furthermore, the outer walls of the upper and lower threaded plugs are provided with a first piston oil seal through a reserved groove, and the first piston oil seal is attached to the inner wall of the oil cavity.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention uses hydraulic power to drive the rotating component to rotate. The rotating component is provided with an inclined surface and an arc-shaped boss near the push rod piston rod. The inclined surface and arc-shaped boss cause the push rod piston rod to rise. Since the rotational motion is more stable than the previous direct push method and the torque transmission is more effective, the stability and efficiency of this hydraulic cylinder are improved during operation, and it can provide stronger thrust.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-6 As shown, the high-thrust impeller cylinder includes a cylinder body 1 and a cylinder body top cover 2. The top of the cylinder body 1 is connected to the cylinder body top cover 2 by screws 17. An oil cavity 11 is provided inside the cylinder body 1. An upper threaded plug 12 and a lower threaded plug 3 are respectively fixed to the inner wall of the oil cavity 11 near the top and bottom ends by threads. A rotating piston rod 4 is fitted inside the lower threaded plug 3 and the upper threaded plug 12. Blades 8 are provided at both ends of the rotating piston rod 4. A hexagonal positioning head 18 is provided at the top of the rotating piston rod 4. A push rod piston rod 6 is provided inside the cylinder body top cover 2 near the top end. A rotating base 5 is provided at the lower end of the push rod piston rod 6. A hexagonal positioning groove 19 is provided at the bottom of the rotating base 5. The hexagonal positioning groove 19 is fitted outside the hexagonal positioning head 18. A group of oil inlet and outlet ports 10 are provided at the bottom and one end of the outer wall of the cylinder body 1. A group of oil inlet and outlet ports 9 are provided at the other end of the bottom and outer wall of the cylinder body 1.

[0025] In this embodiment, by introducing hydraulic oil into the A group inlet / outlet port 9 or the B group inlet / outlet port 10, the blade 8 is subjected to hydraulic pressure, which drives the rotating piston rod 4 to rotate. When the rotating piston rod 4 rotates, it drives the hexagonal positioning head 18 to rotate. When the hexagonal positioning head 18 rotates, it causes the hexagonal positioning groove 19 and the rotating base 5 to rotate, ultimately driving the push rod piston rod 6 to rise upward. The rotating parts are driven to rotate by hydraulic pressure, which in turn drives the push rod piston rod 6 to rise. Because the rotational movement is more stable and the torque transmission is more effective, the stability and efficiency of this hydraulic cylinder are improved during operation, and it can provide stronger thrust.

[0026] like Figure 1 , 2 As shown in Figures 3 and 6, an anti-rotation block 21 is provided at the top of the cylinder top cover 2 near the edge, and an anti-rotation groove 7 is provided at the top of the piston rod 6 near the edge. The anti-rotation block 21 is locked in the anti-rotation groove 7. Through the cooperation of the anti-rotation block 21 and the anti-rotation groove 7, the piston rod 6 will only move up and down and will not rotate.

[0027] Among them, the oil inlet / outlet 9 of group A and the oil inlet / outlet 10 of group B are both connected to the oil chamber 11. When oil enters through the oil inlet / outlet 9 of group A, it pushes the rotating piston rod 4 and the blade 8 to rotate in the forward direction in the oil chamber 11. When oil enters through the oil inlet / outlet 10 of group B, it pushes the rotating piston rod 4 and the blade 8 to rotate in the reverse direction in the oil chamber 11.

[0028] In this embodiment, as shown... Figure 1 , 5 As shown in Figure 6, by introducing hydraulic oil into the oil inlet / outlet 9 of group A or the oil inlet / outlet 10 of group B, it is convenient to apply external force to the blade 8 in a clockwise or counterclockwise direction, thereby driving the rotating piston rod 4 to rotate in the forward or reverse direction.

[0029] like Figure 4 and 5 As shown, a spring-loaded pad 13 is provided on the inner side of the anti-rotation block 21 at the top of the cylinder top cover 2. The bottom of the spring-loaded pad 13 contacts the top disc end face of the push rod piston rod 6. When the rotating piston rod 4 stops applying external force, the spring-loaded pad 13 can drive the push rod piston rod 6 to return to its original position downward.

[0030] The push rod piston rod 6 and the rotating base 5 are both provided with contact surfaces near each other. Both sets of contact surfaces are provided with arc-shaped bosses 22 near the central axis, and both contact surfaces have two sets of inclined surfaces 16 extending from the arc-shaped bosses 22 to the edge. When the two sets of contact surfaces rotate to the fit state, it is the retracted state of the push rod piston rod 6 being lifted. When the two sets of contact surfaces rotate to the position of the arc-shaped bosses 22 and contact each other, it is the highest state of the push rod piston rod 6 being lifted.

[0031] In this embodiment, as shown... Figure 2 , 3 As shown in Figure 4, when the two sets of contact surfaces rotate to the contact state, it is the retracted state of the push rod piston rod 6 being lifted. When the two sets of contact surfaces rotate to the position of the arc-shaped boss 22 and come into contact, it is the highest state of the push rod piston rod 6 being lifted, thus realizing the push rod piston rod 6 being pushed to different heights.

[0032] like Figure 4 and 5 As shown, the lower threaded plug 3 and the upper threaded plug 12 are both provided with mounting force holes 15 at locations far apart from each other. The lower threaded plug 3 and the upper threaded plug 12 can be rotated and disassembled by inserting the tip of the external snap ring pliers into the mounting force holes 15.

[0033] Among them, the inner walls of the upper threaded plug 12 and the lower threaded plug 3 are provided with a second piston oil seal 20 through the mounting groove, and the second piston oil seal 20 is sleeved on the outer wall of the rotating piston rod 4.

[0034] In this embodiment, as shown... Figure 4 and 5 As shown, the second piston oil seal 20 facilitates the sealing between the outer wall of the rotating piston rod 4 and the lower threaded plug 3 and the upper threaded plug 12.

[0035] Among them, the outer walls of the upper threaded plug 12 and the lower threaded plug 3 are provided with a first piston oil seal 14 through a reserved groove. The first piston oil seal 14 fits against the inner wall of the oil cavity 11, such as Figure 4 and 5 As shown, the first piston oil seal 14 can seal the inner wall of the oil chamber 11 with the lower threaded plug 3 and the upper threaded plug 12.

[0036] Working principle: Both group A inlet / outlet 9 and group B inlet / outlet 10 are externally connected to an oil circuit. Valves and oil pumps are installed on the external oil circuit. Hydraulic oil is introduced into group A inlet / outlet 9 or group B inlet / outlet 10, causing the hydraulic oil to enter the oil chamber 11. This hydraulic oil applies a pushing force to the vane 8 from different directions, thereby driving the rotating piston rod 4 to rotate in the forward or reverse direction. The vane 8, subjected to hydraulic pressure, drives the rotating piston rod 4 to rotate. When the rotating piston rod 4 rotates, it drives the hexagonal positioning head 18 to rotate. The rotation of the hexagonal positioning head 18 causes the hexagonal positioning groove 19 and the rotating base 5 to rotate. Through the cooperation of the anti-rotation locking block 21 and the anti-rotation locking groove 7, the push rod piston rod 6 will only rotate in one direction. The lifting mechanism does not rotate, ultimately driving the push rod piston rod 6 upward. When the rotating piston rod 4 stops applying external force, the return washer 13 can drive the push rod piston rod 6 downward to reset. When the two sets of contact surfaces rotate to the contact state, it is the retracted state of the push rod piston rod 6. When the two sets of contact surfaces rotate to the position of the arc-shaped boss 22 and contact each other, it is the highest state of the push rod piston rod 6, realizing the push rod piston rod 6 to be pushed to different heights. This impeller cylinder drives the rotating parts to rotate through hydraulic pressure, which in turn drives the push rod piston rod 6 to rise. Because the rotational movement is more stable and the torque transmission is more effective, the stability and efficiency of this cylinder during operation are improved, and it can provide stronger thrust.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
