Description

Technical Field

[0001] This utility model relates to the field of damper technology, and in particular to a dustproof damper for industrial equipment. Background Technology

[0002] Industrial dampers are essential components in the operation of industrial equipment. They generate controllable resistance to slow down or suppress the movement, vibration and impact of the equipment, thereby ensuring the stability and safety of the equipment operation and extending the service life of the equipment. They are widely used in various industrial scenarios such as cranes, automated production lines, machine tools, and elevators.

[0003] Hydraulic dampers are one of the commonly used damper types in the industrial field. They generate damping force by using the flow of hydraulic oil in the piston cavity. They have the characteristics of large and adjustable damping force, fast response speed and strong load-bearing capacity, and can effectively meet the buffering, deceleration and vibration reduction needs of high-load and high-speed industrial equipment.

[0004] In industrial manufacturing, especially in dusty factories, hydraulic dampers face severe dust interference problems. Airborne dust easily adheres to the piston rod surface of the hydraulic damper, and with the reciprocating movement of the piston rod, this dust is easily carried into the interior of the damper, causing wear and blockage of internal components, and even leading to damper failure, seriously affecting its normal operation. Therefore, a dustproof industrial equipment damper is proposed to solve these problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3 One embodiment of this utility model is a dustproof damper for industrial equipment, including a hydraulic damper 1, a first connecting block 2 fixedly connected to the piston end of the hydraulic damper 1, a second connecting block 3 fixedly connected to the bottom end of the hydraulic damper 1, and a dustproof mechanism 4 provided on the outer wall of the hydraulic damper 1.

[0020] Reference Figure 1 - Figure 3 The dustproof mechanism 4 includes a dustproof sleeve 41, which is snapped onto the outer wall of the hydraulic damper 1. The dustproof sleeve 41 can cover the outer wall of the hydraulic damper 1 to prevent dust from adhering to the outer wall of the hydraulic damper 1. A chuck 42 is fixedly connected to the bottom of the dustproof sleeve 41, and a bellows 43 is fixedly connected to the top of the dustproof sleeve 41. The bellows 43 can cover the piston rod between the first connecting block 2 and the hydraulic damper 1 to prevent dust from adhering to the outer wall of the piston rod.

[0021] Reference Figure 5A sealing ring 44 is fixedly connected to the inner wall of the chuck 42, and a slot 45 is provided on the outer wall of the hydraulic damper 1 for the sealing ring 44 to be inserted. The connection between the dust cover 41 and the hydraulic damper 1 can be sealed by the cooperation of the sealing ring 44 and the slot 45, so as to prevent dust from entering the interior of the dust cover 41 from the gap between the hydraulic damper 1 and the dust cover 41.

[0022] Reference Figure 3 and Figure 6 A ferrule 46 is fixedly connected to the top of the corrugated pipe 43. A disassembly and assembly mechanism 5 is provided inside the ferrule 46 and at the bottom of the chuck 42. A sealing gasket 47 is fixedly connected to the inner wall of the ferrule 46. A sealing groove 48 is provided on the outer wall of the first connecting block 2 for the sealing gasket 47 to be inserted. The sealing gasket 47 and the sealing groove 48 can be used to seal the connection between the ferrule 46 and the first connecting block 2, so as to prevent dust from entering the interior of the corrugated pipe 43 through the gap between the ferrule 46 and the first connecting block 2.

[0023] Reference Figure 4 - Figure 5 The disassembly and assembly mechanism 5 includes a rotating shaft 51, which passes through and is rotatably connected to the inner wall of the chuck 42. One end of the rotating shaft 51 is fixedly connected to an eccentric wheel 52, and the other end is fixedly connected to a handle 53. By rotating the rotating shaft 51 through the handle 53, the eccentric wheel 52 can be driven to separate from the bottom of the hydraulic damper 1. The eccentric wheel 52 and the rotating shaft 51 are in an eccentric state, and the upper surface of the eccentric wheel 52 is in contact with the bottom of the hydraulic damper 1. When the upper surface of the eccentric wheel 52 is in contact with the bottom of the hydraulic damper 1, the mechanism is in operation. After the bottom of 1, the eccentric wheel 52 will limit the chuck 42, so that the chuck 42 limits the dust cover 41, and the dust cover 41 can be locked on the outer wall of the hydraulic damper 1. A torsion spring 54 is provided at the connection between the rotating shaft 51 and the chuck 42. One end of the torsion spring 54 is fixedly connected to the inner wall of the chuck 42, and the other end of the torsion spring 54 passes through and is fixedly connected to the inner wall of the handle 53. Through the elasticity of the torsion spring 54 and the handle 53, the rotating shaft 51 can be driven to rotate and reset on the inner wall of the chuck 42.

[0024] Reference Figure 6The inner wall of the sleeve 46 has a through hole 55, and a steel ball 56 is rolledly connected to the inner wall of the through hole 55. The outer wall of the first connecting block 2 has a limiting hole 57 for the steel ball 56 to be inserted. By using the steel ball 56 to cooperate with the limiting hole 57, the sleeve 46 can be limited to the outer wall of the first connecting block 2, thereby completing the docking of the sleeve 46 and the first connecting block 2. The outer wall of the sleeve 46 is slidably connected to a sliding sleeve 58. The inner wall of the sliding sleeve 58 is attached to the outer wall of the steel ball 56. By using the inner wall of the sliding sleeve 58 to press against the steel ball 56, the steel ball 56 can always be stuck inside the limiting hole 57. The bottom of the sliding sleeve 58 is fixedly connected to a spring 59. The end of the spring 59 away from the sliding sleeve 58 is fixedly connected to the outer wall of the sleeve 46. The elasticity of the spring 59 can push the sliding sleeve 58 upward, so that the sliding sleeve 58 slides upward and resets on the outer wall of the sleeve 46.

[0025] Working principle: During use, the dust cover 41 can cover the outer wall of the hydraulic damper 1 to prevent dust from adhering to the outer wall of the hydraulic damper 1. At the same time, the bellows 43 can cover the piston rod between the first connecting block 2 and the hydraulic damper 1 to prevent dust from adhering to the outer wall of the piston rod and causing the piston rod to bring dust into the interior of the hydraulic damper 1 during the reciprocating movement. In addition, the bellows 43 has good extensibility and will not interfere with the reciprocating movement of the piston rod of the hydraulic damper 1.

[0026] The sealing ring 44 and the slot 45 work together to seal the connection between the dust cover 41 and the hydraulic damper 1, preventing dust from entering the dust cover 41 through the gap between the hydraulic damper 1 and the dust cover 41. The sealing gasket 47 and the sealing groove 48 work together to seal the connection between the sleeve 46 and the first connecting block 2, preventing dust from entering the bellows 43 through the gap between the sleeve 46 and the first connecting block 2. The sealing ring 44 and the sealing gasket 47 work together to keep the bellows 43 and the inside of the dust cover 41 clean, thereby effectively isolating dust and preventing the hydraulic damper 1 from being disturbed by dust.

[0027] By rotating the shaft 51 with the handle 53, the shaft 51 rotates on the inner wall of the chuck 42 and compresses the torsion spring 54. While the shaft 51 is rotating, it will drive the eccentric wheel 52 to rotate synchronously. The rotation of the eccentric wheel 52 can separate its upper surface from the bottom of the hydraulic damper 1, thereby releasing the limit on the chuck 42. Then the chuck 42 and the dust cover 41 can be removed from the outer wall of the hydraulic damper 1 for maintenance. Conversely, when the upper surface of the eccentric wheel 52 is attached to the bottom of the hydraulic damper 1, the dust cover 41 can be clamped on the outer wall of the hydraulic damper 1 to protect the hydraulic damper 1 from dust.

[0028] Pushing the sliding sleeve 58 downwards causes it to slide down the outer wall of the ferrule 46 and compress the spring 59, thus dislocating the sliding sleeve 58 from the steel ball 56. This prevents the sleeve from contacting the steel ball 56 internally, allowing the steel ball 56 to move freely within the through hole 55. Then, pushing the ferrule 46 upwards causes it to slide upwards on the outer wall of the first connecting block 2. Simultaneously, the steel ball 56 is compressed by the first connecting block 2, causing it to roll within the through hole 55 and gradually move away from the limiting hole 57. This allows the steel ball 56 to move out of the limiting hole 57, releasing it from its constraint on the ferrule 46. The ferrule 46 can then be separated from the first connecting block 2, allowing the bellows 43, along with the dust cover 41, to be removed from the outer wall of the hydraulic damper 1 for easier handling. The operator inspects the hydraulic damper 1; conversely, when the steel ball 56 is aligned with the limiting hole 57, the sliding sleeve 58 is loosened, causing the spring 59 to push the sliding sleeve 58 upward. At this time, the sliding sleeve 58 will slide upward and reset on the outer wall of the sleeve 46. When the sliding sleeve 58 contacts the steel ball 56 during the upward sliding process, it will squeeze the steel ball 56, causing the steel ball 56 to be pushed into the interior of the limiting hole 57. At this time, the inner wall of the sliding sleeve 58 can hold the steel ball 56 in place, so that the steel ball 56 is always stuck inside the limiting hole 57. At this time, the steel ball 56 and the limiting hole 57 can limit the sleeve 46 to the outer wall of the first connecting block 2, thereby completing the docking of the sleeve 46 and the first connecting block 2, so that the bellows 43 can cover the piston rod of the hydraulic damper 1 to prevent dust from entering the piston rod of the hydraulic damper 1.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
