Description

Technical Field

[0001] This utility model relates to a hydraulic support foot, specifically a hydraulic support foot that can be freely adjusted and positioned, belonging to the technical field of mechanical equipment support components. Background Technology

[0002] Mobile crushing and screening stations for mining are equipment used in mining, waste treatment and other fields. They can crush large pieces of ore into the required particle size for subsequent processing and utilization. They are widely used in mining and other fields. Support feet are usually installed at the bottom of the mobile crushing and screening station to increase its stability and adjustability during installation and use.

[0003] Existing support legs have their lower ends in contact with the ground and their upper ends installed together with the mobile crushing and screening station equipment in the mine to support and fix the equipment. The length of the support legs can be adjusted by extending and retracting the support legs through hydraulic cylinders, thereby adjusting the height of the mobile crushing and screening station equipment. However, some existing support legs are not stable enough after adjustment, which may affect the normal operation and service life of the equipment. Therefore, we provide a hydraulic support leg with free adjustable positioning to solve the above problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a freely adjustable and positioning hydraulic support foot, and the specific technical solution is as follows:

[0005] An adjustable hydraulic support foot includes a hydraulic foot, a positioning support movably connected to the upper part of the hydraulic foot, two positioning screws fixedly connected to the upper part of the positioning support, and the two positioning screws located at both ends of the positioning support. Two positioning nuts are threaded onto the outer surface of each positioning screw. A fixing plate is pressed and fixed between the two positioning nuts. A guide sleeve is fixedly connected to the side of the fixing plate. A guide inner cylinder is slidably connected to the inner wall of the guide sleeve. The lower surface of the guide inner cylinder is fixedly connected to the positioning support. The guide sleeve and guide inner cylinder are located between the two positioning screws. A hydraulic pushing mechanism is provided inside the guide sleeve and guide inner cylinder.

[0006] Preferably, the hydraulic actuation mechanism includes a hydraulic cylinder and a hydraulic push rod, wherein the outer surface of the hydraulic push rod is slidably connected to the hydraulic cylinder.

[0007] Preferably, a second fixing pin is installed at the upper end of the hydraulic cylinder, the second fixing pin is installed at the upper end of the guide sleeve, and the lower end of the hydraulic push rod is connected to the guide inner cylinder.

[0008] Preferably, the inner wall of the hydraulic foot is rotatably connected to a first fixing pin, and the lower surface of the positioning support is fixedly connected to a fixing block, the inner wall of the fixing block being rotatably connected to the first fixing pin.

[0009] Preferably, a limiting block is fixedly connected to the lower surface of the positioning support, the inner wall of the limiting block is rotatably connected to the first fixing pin, there are two limiting blocks, and their sides are in contact with the hydraulic foot.

[0010] Preferably, the positioning nut is a pentagonal high-strength nut, the guide sleeve and the guide inner cylinder are both made of metal alloy material, and a balance valve is provided above the guide sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This freely adjustable hydraulic support foot, equipped with positioning screws and nuts, allows for smooth height adjustment when the equipment height needs to be adjusted. A hydraulic push mechanism drives the guide sleeve and guide inner cylinder to slide, achieving stable height increase and decrease under the constraint of the guide sleeve and guide inner cylinder. After the height adjustment is complete, rotating the positioning nuts clamps the fixing plate in the middle, securing the guide sleeve and achieving stable positioning and reinforcement. This improves the stability and reliability of equipment operation, thus solving the problem that some existing support feet are not sufficiently stable after adjustment, potentially affecting the normal operation and service life of the equipment.

[0013] 2. The freely adjustable hydraulic support foot is equipped with components such as a hydraulic foot and a positioning support. The positioning support is connected to the hydraulic foot by a first fixing pin, so that the hydraulic foot can tilt at a certain angle relative to the positioning support. When the ground or mounting surface is uneven, the lower surface of the hydraulic foot can make full contact with the ground. The lower surface of the hydraulic foot is roughened to increase the friction with the ground or mounting surface, thereby increasing its applicability. Attached Figure Description

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] Please see Figures 1-5 The system includes a hydraulic foot 1, with a positioning support 2 movably connected to the top of the hydraulic foot 1. Two positioning screws 3 are fixedly connected to the upper part of the positioning support 2, located at both ends of the positioning support 2. Two positioning nuts 4 are threaded onto the outer surface of each positioning screw 3. A fixing plate 5 is pressed and fixed between the two positioning nuts 4. A guide sleeve 8 is fixedly connected to the side of the fixing plate 5. A guide inner cylinder 10 is slidably connected to the inner wall of the guide sleeve 8. The lower surface of the guide inner cylinder 10 is fixedly connected to the positioning support 2. The guide sleeve 8 and the guide inner cylinder 10 are located between the two positioning screws 3. A hydraulic pushing mechanism is installed inside the guide sleeve 8 and the guide inner cylinder 10. The hydraulic foot 1 consists of a flat plate and two vertical plates on both sides. The lower surface of the hydraulic foot 1 contacts the ground and is roughened to increase friction with the ground or mounting surface. The positioning support 2 fixes two positioning screws 3. There are two fixing plates 5, which are fixed on both sides of the guide sleeve 8. The two fixing plates 5 have slightly different shapes for ease of use. The bottom of the fixing plate 5 is provided with a horizontal plate so that it can be pressed and fixed by two positioning nuts 4. When the hydraulic push mechanism extends or shortens, it slides between the guide sleeve 8 and the guide inner cylinder 10 to achieve overall lifting. Under the guidance of the guide sleeve 8 and the guide inner cylinder 10, the height is raised and lowered smoothly. After the height is adjusted to the correct position, the positioning nut 4 is rotated. The positioning screws 3 cooperate with the positioning nut 4 to fix the fixing plate 5, thereby positioning and reinforcing the guide sleeve 8 and the guide inner cylinder 10 to ensure the stable positioning of the support foot after adjustment, increase the firmness, and improve the stability and reliability of the equipment operation.

[0022] The hydraulic actuation mechanism includes a hydraulic cylinder 7 and a hydraulic push rod 9. The outer surface of the hydraulic push rod 9 is slidably connected to the hydraulic cylinder 7. Under the action of the hydraulic system, the hydraulic push rod 9 can extend or retract from the inside of the hydraulic cylinder 7. This is a commonly used hydraulic technology that is already very common and will not be elaborated on further here.

[0023] A second fixing pin 12 is installed on the upper end of the hydraulic cylinder 7. The second fixing pin 12 is installed on the upper end of the guide sleeve 8. The lower end of the hydraulic push rod 9 is connected to the guide inner cylinder 10. The second fixing pin 12 is fixedly connected to both the guide sleeve 8 and the hydraulic cylinder 7. The upper part of the hydraulic cylinder 7 is fixed to the guide sleeve 8 by the second fixing pin 12. There are two second fixing pins 12. The other one fixes the hydraulic push rod 9 to the guide inner cylinder 10. In this way, when the hydraulic push mechanism applies pressure, it can drive the guide sleeve 8 and the hydraulic push rod 9 to move away from or closer to each other, thereby realizing the overall lifting and lowering movement.

[0024] The inner wall of the hydraulic foot 1 is rotatably connected to a first fixing pin 11, and the lower surface of the positioning support 2 is fixedly connected to a fixing block 13. The inner wall of the fixing block 13 is rotatably connected to the first fixing pin 11. The positioning support 2 and the hydraulic foot 1 are connected together by the first fixing pin 11, and the fixing block 13 provides support, so that the hydraulic foot 1 can tilt at a certain angle relative to the positioning support 2. When the ground or installation surface is not stable, the lower surface of the hydraulic foot 1 can be in complete contact with the ground.

[0025] The lower surface of the positioning support 2 is fixedly connected to a limiting block 14. The inner wall of the limiting block 14 is rotatably connected to the first fixing pin 11. There are two limiting blocks 14, and their sides are in contact with the hydraulic foot 1. The two limiting blocks 14 are in contact with the hydraulic foot 1 to prevent horizontal displacement and sliding between the positioning support 2 and the hydraulic foot 1, thereby increasing the stability of the application.

[0026] The positioning nut 4 is a pentagonal high-strength nut. The guide sleeve 8 and the guide inner cylinder 10 are both made of metal alloy material. A balance valve 6 is set above the guide sleeve 8. The guide sleeve 8 and the guide inner cylinder 10 have a certain strength and can resist pressure and bending to ensure the overall stability.

[0027] In use, this invention involves installing the device at the bottom of the equipment. When the equipment height needs adjustment, the hydraulic system controls the hydraulic push rod 9 to move. The hydraulic push rod 9 pushes or pulls the hydraulic cylinder 7, changing the extension length of the hydraulic push rod 9. This causes the guide sleeve 8 and the guide inner cylinder 10 to slide together, achieving stable height adjustment under the constraint of the guide sleeve 8 and the guide inner cylinder 10, thus increasing stability. After the height adjustment is complete, rotating the positioning nuts 4 clamps the fixing plate 5 in the middle, securing the guide sleeve 8 and achieving stable positioning and reinforcement, improving the stability and reliability of the equipment operation.

[0028] Compared with existing technologies, this device can adapt to different ground conditions and equipment installation requirements through the hydraulic foot 1. The positioning support 2 is connected to the hydraulic foot 1 by the first fixing pin 11, and the fixing block 13 provides support, so that the hydraulic foot 1 can tilt at a certain angle relative to the positioning support 2. When the ground or installation surface is not stable, the lower surface of the hydraulic foot 1 can make full contact with the ground. The lower surface of the hydraulic foot 1 is roughened to increase the friction with the ground or installation surface, thereby increasing its applicability.
