Description

Technical Field

[0001] This utility model relates to the field of rotary cylinder technology, specifically an angle-adjustable rotary cylinder. Background Technology

[0002] Hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy and perform linear reciprocating motion (or oscillating motion). They are simple in structure and reliable in operation. When used to achieve reciprocating motion, they can eliminate the need for a speed reduction device and have no transmission backlash, resulting in smooth movement. Therefore, they are widely used in the hydraulic systems of various machines. Angle-adjustable rotary cylinders are cylinder devices that can adjust their rotation angle within a certain range. They combine the linear and rotary motion of the cylinder and achieve angle adjustability through a specific transmission mechanism.

[0003] The publication number CN215980655U discloses an angle-adjustable rotary cylinder. By setting up a transmission mechanism, a servo motor is started to drive a transmission shaft to rotate. Simultaneously, the rotation of the transmission shaft drives a drive gear to rotate. The drive gear then causes a rack to slide along the inner walls of two limiting plates and the inner walls of the telescopic lugs, thus limiting its movement. At the same time, it drives a driven gear to rotate, thereby rotating the cylinder and achieving angle adjustment. The lubricating oil filled in the housing greatly reduces frictional losses between the drive gear, driven gear, and rack, significantly improving the device's service life. Although this device can adjust the angle of the rotary cylinder, it requires adding telescopic lugs to both sides of the housing, which takes up considerable space. Furthermore, the required installation height for the rotary cylinder varies, making installation inconvenient. Therefore, we propose an angle-adjustable rotary cylinder. Utility Model Content

[0004] The purpose of this invention is to provide an angle-adjustable rotary hydraulic cylinder.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: an angle-adjustable rotary cylinder, comprising a housing, a rotary cylinder being disposed through one side of the housing, a toothed block being installed on the side wall of the rotary cylinder, an isolation box being installed at the bottom inside the housing, a first motor and a second motor being disposed inside the isolation box, a first gear being installed on one side of the first motor, a second gear being installed on one side of the second motor, sliding plates being disposed through the four corners of the bottom inside the housing, a base plate being installed at the lower end of the sliding plate, a toothed plate being installed on one side of the upper end of the base plate, a top plate being installed at the upper end of the housing, and multiple sets of heat-conducting plates being disposed at the center of the upper end of the top plate.

[0006] Preferably, the rotary cylinder is fixedly connected to the toothed block, and the toothed block is meshed with the first gear.

[0007] Preferably, the toothed plate is meshed with the second gear, and the toothed plate passes through the housing.

[0008] Preferably, the slide plate is fixedly connected to the base plate, and the slide plate is slidably connected to the box body.

[0009] Preferably, a first protective box and a second protective box are respectively installed on both sides of the upper end of the top plate. A third motor is provided on one side of the first protective box. A rotating rod is installed at one end of the third motor. A transmission wheel is installed on both sides of the rotating rod. A transmission belt is installed on the transmission wheel. A mounting frame is installed inside the first and second protective boxes. A rotating column is installed on one side of the mounting frame. A fan blade is installed on one side of the rotating column. A placement plate is installed on both sides of the first and second protective boxes. A filter plate is provided inside the placement plate.

[0010] Preferably, the rotating rod passes through the first protective box and the second protective box, and the rotating rod is rotatably connected to the first protective box and the second protective box.

[0011] Preferably, the rotating rod is fixedly connected to the transmission wheel, and the transmission wheel is rotatably connected to the rotating column via a transmission belt.

[0012] Using the above technical solution, when the rotary cylinder needs adjustment, the first motor is started, causing the rotary cylinder to rotate inside the housing with the cooperation of the gear block and the first gear. When the rotary cylinder is adjusted to the required angle, it stops. Then, through the cooperation of the second motor, the second gear and the gear plate, the rotary cylinder can be driven to rise through the housing. After rising to the required height, it stops. Then, through the cooperation of the sliding plate and the base plate, the rising of the rotary cylinder is made more stable. This allows the angle-adjustable rotary cylinder to be quickly rotated 360 degrees, and the height of the rotary cylinder can be adjusted according to the installation position.

[0013] By adopting the above technical solution, the rotation of the hydraulic cylinder, in conjunction with the third motor, the rotating rod, and the transmission wheel, drives the transmission belt to rotate. The transmission belt, through the rotating column, drives the fan blades to rotate, allowing the fan blades inside the first and second protection boxes to dissipate heat from the heat-conducting plate. Furthermore, through the cooperation of the filter plate, the intake air can be filtered to prevent external dust from adhering to the fan blades, thus reducing their heat dissipation capacity. The first and second protection boxes can then protect the internal fan blades. The angle-adjustable rotary hydraulic cylinder can protect the fan blades and prevent dust from adhering to them.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figure 1-4 This utility model provides a technical solution: an angle-adjustable rotary cylinder, including a housing 1, a rotary cylinder 2 through one side of the housing 1, a toothed block 3 installed on the side wall of the rotary cylinder 2, an isolation box 4 installed at the bottom inside the housing 1, a first motor 5 and a second motor 6 respectively installed inside the isolation box 4, a first gear 7 installed on one side of the first motor 5, a second gear 8 installed on one side of the second motor 6, sliding plates 10 through the four corners of the bottom inside the housing 1, a base plate 11 installed at the lower end of the sliding plate 10, a toothed plate 9 installed on one side of the upper end of the base plate 11, a top plate 12 installed at the upper end of the housing 1, and multiple sets of heat-conducting plates 13 arranged at the center of the upper end of the top plate 12.

[0022] The rotary cylinder 2 is fixedly connected to the toothed block 3, and the toothed block 3 is meshed with the first gear 7.

[0023] The toothed plate 9 meshes with the second gear 8, and the toothed plate 9 passes through the housing 1.

[0024] The slide plate 10 is fixedly connected to the base plate 11, and the slide plate 10 is slidably connected to the box body 1.

[0025] Specifically, when the angle of the rotary cylinder 2 needs to be rotated, the first motor 5 is started, which drives the first gear 7 to rotate. When the first gear 7 rotates, it drives the rotary cylinder 2 to rotate inside the housing 1 through the tooth block 3 on the side wall of the rotary cylinder 2. Then, when the rotary cylinder 2 rotates to the required angle, it stops. When the height of the rotary cylinder 2 needs to be adjusted, the second motor 6 is started, which drives the second gear 8 to rotate. When the second gear 8 rotates, it pushes the toothed plate 9 that meshes with it to slide downward inside the housing 1, so that the toothed plate 9 lifts the housing 1. At the same time, the slide plate 10 slides inside the housing 1, thereby causing the housing 1 to drive the rotary cylinder 2 inside to rise. This allows the angle-adjustable rotary cylinder to quickly rotate the rotary cylinder 2 360 degrees, and the height of the rotary cylinder 2 can be adjusted according to the installation position.

[0026] Example 2:

[0027] Please see Figure 1-4 This utility model provides a technical solution: an angle-adjustable rotary cylinder, with a first protective box 14 and a second protective box 15 respectively installed on both sides of the upper end of the top plate 12. A third motor 16 is provided on one side of the first protective box 14, and a rotating rod 17 is installed at one end of the third motor 16. Transmission wheels 18 are installed on both sides of the rotating rod 17, and transmission belts 19 are installed on the transmission wheels 18. Mounting frames 20 are installed inside the first protective box 14 and the second protective box 15. A rotating column 21 is installed on one side of the mounting frame 20, and a fan blade 22 is installed on one side of the rotating column 21. Placement plates 23 are installed on both sides of the first protective box 14 and the second protective box 15, and filter plates 24 are provided inside the placement plates 23.

[0028] The rotating rod 17 passes through the first protective box 14 and the second protective box 15, and the rotating rod 17 is rotatably connected to the first protective box 14 and the second protective box 15.

[0029] The rotating rod 17 is fixedly connected to the transmission wheel 18, and the transmission wheel 18 is rotatably connected to the rotating column 21 through the transmission belt 19.

[0030] Specifically, by sliding the filter plate 24 into the placement plate 23, and then adjusting the angle of the rotating cylinder 2, heat is generated inside the housing 1, which is absorbed by the heat-conducting plate 13. At this time, the third motor 16 is started, which drives the rotating rod 17 to rotate. When the rotating rod 17 rotates, it drives the transmission wheel 18 on the side wall to rotate as well. Then, the transmission wheel 18 drives the rotating column 21 to rotate in the mounting frame 20 through the transmission belt 19, which in turn drives the fan blade 22 to rotate. At this time, the fan blade 22 will draw in the external air and dissipate heat on the heat-conducting plate 13. When the fan blade 22 draws in air, the air will enter through the filter plate 24. The filter plate 24 will filter the air to prevent dust from entering. Then, the first protective box 14 and the second protective box 15 will block external debris, so that the angle-adjustable rotating cylinder can protect the fan blade 22 and prevent dust from sticking to the fan blade 22.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
