Description

Technical Field

[0001] This application relates to the field of hydraulic cylinder technology, specifically to a high-degree-of-freedom hydraulic cylinder disassembly assembly that is easy to maintain and resistant to high dust. Background Technology

[0002] A hydraulic cylinder is an actuator that converts hydraulic energy into mechanical energy. It uses the pressure of hydraulic oil to drive the piston rod to move, achieving linear reciprocating motion or oscillation. With the widespread application of hydraulic cylinders, in order to avoid the piston rod's service life being affected by excessive dust during operation, a high-degree-of-freedom hydraulic cylinder disassembly assembly that is easy to maintain and resistant to high dust is needed.

[0003] In existing technologies, hydraulic cylinders extend and retract by pushing a piston rod. However, in dusty environments, the piston rod will attract a large amount of dust during its extension. Over time, this dust will accumulate on the piston rod, affecting the seal between the hydraulic cylinder and the piston rod, leading to leakage and impacting the service life. Therefore, we propose a high-degree-of-freedom hydraulic cylinder disassembly assembly that is easy to maintain and resistant to high dust levels. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a high-degree-of-freedom hydraulic cylinder disassembly assembly that is easy to maintain and resistant to high dust levels, thus solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: a high-degree-of-freedom hydraulic cylinder disassembly assembly that is easy to maintain and resistant to high dust, comprising a fixing plate, a dustproof mechanism, a ventilation mechanism, and a hydraulic cylinder body. The fixing plate has a dustproof mechanism on one side, and the hydraulic cylinder body is located inside the dustproof mechanism. The dustproof mechanism includes a first protective shell, a second protective shell, and a dustproof protective shell. The first protective shell and the second protective shell are adapted to each other, and the hydraulic cylinder body is located inside the first protective shell and the second protective shell. The dustproof protective shell is located on one side of the hydraulic cylinder body, and the dustproof protective shell is slidably connected to the first protective shell and the second protective shell.

[0008] By adopting the above technical solution, the first protective shell and the second protective shell can effectively protect the hydraulic cylinder body. When the hydraulic cylinder body extends or retracts, the dustproof protective shell can be moved to prevent external dust from accumulating on the piston rod during the extension or retraction of the hydraulic cylinder body, thereby effectively improving the service life of the hydraulic cylinder body.

[0009] Preferably, one side of the fixing plate is fixedly connected to the first protective shell, and a snap-fit ​​groove is provided on one side of the first protective shell.

[0012] By adopting the above technical solution, the hydraulic cylinder body moves by driving the dustproof protective shell when it extends and retracts. The dustproof protective shell contacts the first and second protective shells through the internal dustproof sealing gasket. The two guide rods on both sides of the fixed plate facilitate the guide slider to drive the dustproof protective shell to play a guiding role, improve the moving stability of the dustproof protective shell, and prevent dust from entering the interior of the dustproof protective shell through gaps when it extends and retracts.

[0013] Preferably, a sealing groove is fixedly installed on one side of the dustproof protective shell, the output end of the hydraulic cylinder body is adapted to the sealing groove, and a first bolt is threadedly connected to one side of the sealing groove, one end of the first bolt extending into the interior of the sealing groove and connecting to the output end of the hydraulic cylinder body.

[0014] By adopting the above technical solution, the first bolt on one side of the sealing groove is fixed to the output end of the hydraulic cylinder body, which facilitates the improvement of stability when the hydraulic cylinder body extends and retracts. At the same time, the dustproof protective shell can be disassembled by loosening the first bolt, which facilitates subsequent maintenance work.

[0016] By adopting the above technical solution, the air exchange frame facilitates the air pressure generated when the hydraulic cylinder body drives the dustproof protective shell to extend and retract, and the dustproof frame that slides inside the air exchange frame facilitates disassembly and cleaning. The dustproof filter screen inside the dustproof frame facilitates the filtration of dust during the air exchange process, preventing dust from entering the interior. Finally, the second bolt is used for fixing.

[0017] Preferably, a hinge seat is hinged to the other side of the fixing plate, and a mounting plate is fixedly installed on one side of the hinge seat.

[0018] By adopting the above technical solution, the hinge seat hinged to the rear of the fixed plate can be adjusted to adjust the installation angle, making it easy to install in different positions. Finally, the fixing operation is performed through the mounting holes on the mounting plate.

[0031] The first protective shell 201 and the second protective shell 202 provide protection for the hydraulic cylinder body 4. When the hydraulic cylinder body 4 extends or retracts, the dustproof protective shell 208 can be moved. The dustproof protective shell 208 helps to prevent external dust from accumulating on the piston rod when the hydraulic cylinder body 4 extends or retracts, thereby effectively improving the service life of the hydraulic cylinder body 4.

A first bolt 211 is threadedly connected to one side of the sealing groove 210. One end of the first bolt 211 extends into the interior of the sealing groove 210 and connects to the output end of the hydraulic cylinder body 4.

[0035] The second protective shell 202 drives the snap-fit ​​strip 204 on one side to snap into the snap-fit ​​groove 203 on one side of the first protective shell 201. The sealing strip 205 inside the snap-fit ​​groove 203 facilitates tight contact with the snap-fit ​​strip 204, thereby preventing external dust from entering the interior and affecting the use of the hydraulic cylinder body 4. Subsequently, when the hydraulic cylinder body 4 extends or retracts, it drives the dustproof protective shell 208 to move. The dustproof protective shell 208 contacts the first protective shell 201 and the second protective shell 202 through the internal dustproof sealing gasket 209.

[0040] All electrical devices in this plan are powered by an external power source.

[0041] Working principle: During use, the second protective shell 202 drives the snap-fit ​​strip 204 on one side to snap into the snap-fit ​​groove 203 on one side of the first protective shell 201. The sealing strip 205 inside the snap-fit ​​groove 203 facilitates tight contact with the snap-fit ​​strip 204, thereby preventing external dust from entering the interior and affecting the use of the hydraulic cylinder body 4. Subsequently, when the hydraulic cylinder body 4 extends or retracts, it drives the dustproof protective shell 208 to move. The dustproof protective shell 208, through the internal dustproof sealing gasket 209, connects with the first protective shell 201 and the second protective shell 201. The two guide rods 206 on both sides of the fixed plate 1 facilitate the flow guide slider 207 to drive the dustproof protective shell 208 to play a guiding role, so as to prevent dust from entering the interior of the dustproof protective shell 208 through the gap when the hydraulic cylinder body 4 extends and retracts. The first bolt 211 on one side of the sealing groove 210 is fixed to the output end of the hydraulic cylinder body 4, which can improve the stability when the hydraulic cylinder body 4 extends and retracts. At the same time, the dustproof protective shell 208 can be disassembled by loosening the first bolt 211, which is convenient for subsequent maintenance work.
