[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figure 1 - Figure 5 The present application provides an intelligent annular gasket automatic replacement device for heavy-duty machinery, comprising:

[0033] A sub-bracket 2, the lower end of which is provided with an anti-oil sheet 1 for scraping grease on the surface of the annular gasket;

[0034] A disc is installed on the top of the sub-bracket 2, and a plurality of lower linear bearings 8 are embedded on the disc to guide the lifting of the guide rod 5. An upper linear bearing 4 is provided at the center of the disc to guide the screw rod 11, and the inner surface of the upper linear bearing 4 is threadedly connected with the screw rod 11;

[0035] A drive motor 7 mounted on the upper end of the screw rod 11;

[0036] A movable rack component 3 connected to the screw rod 11 is arranged on the inner side of the sub-bracket 2, and gear components 9 are arranged on both sides of the movable rack component 3. Active claws 10 for grabbing the annular gasket are arranged on the front and rear surfaces of the gear component 9. The two groups of active claws 10 can rotate relative to each other or back to back, thereby changing the distance between the lower ends of the two groups of active claws 10, which is convenient for adapting to different apertures of the annular gasket.

[0037] In this embodiment, preferably, the movable rack component 3 includes a lifting rack frame 32 mounted on the inner side of the sub-bracket 2, and the upper and lower ends of the lifting rack frame 32 are mounted on the sub-bracket 2 through fixed buckles 33. The fixed buckles 33 are U-shaped when viewed from above, and form a rectangular structure mounted on the sub-bracket 2 with the lifting rack frame 32, which neither affects the up and down movement of the lifting rack frame 32 nor prevents the lifting rack frame 32 from detaching from the sub-bracket 2. The movable rack component 3 also includes a connecting triangle block 31 installed at the lower end of the screw rod 11, and connecting blocks 34 are provided between the two sides of the lower end of the connecting triangle block 31 and the inner side surfaces of the lifting rack frame 32. The lifting rack frame 32 is a U-shaped structure, which is convenient for being stuck on the inner side of the sub-bracket 2, and the connecting triangle block 31 is rotatably connected to the lower end of the screw rod 11, and the connecting block 34 is rotatably connected to the connecting triangle block 31.

[0038] In this embodiment, preferably, the gear component 9 includes a rotating gear 92 meshing with the teeth of the lifting rack frame 32, and the gear component 9 also includes a gear seat 91 fixed to the outer side of the sub-bracket 2, the rotating gear 92 is rotatably connected to the gear seat 91, and a wheel axle supporting the rotating gear 92 is rotatably arranged inside the gear seat 91, so as to facilitate the stable meshing of the rotating gear 92 and the lifting rack frame 32.

[0039] In this embodiment, preferably, the two movable claws 10 are respectively connected to the two rotating gears 92, and a connecting shaft 93 is provided between the movable claw 10 and the rotating gear 92. The movable claw 10 is detachable and replaceable, so as to be convenient for adapting to annular gaskets of different sizes and materials.

[0040] In this embodiment, preferably, a rotating handle 6 is provided above the disc. The rotating handle 6 is ergonomically designed, and the operator can complete the complicated gasket replacement process with only a small amount of adjustment, avoiding the tedious steps of traditional manual operation. The lower surface of the rotating handle 6 is provided with four movable guide rods 5 that penetrate the lower linear bearing 8 and are exposed below, and a fixed baffle 15 is provided at the lower end of the guide rod 5.

[0041] In summary, first, the entire device is placed in the coupling shaft cylinder, aligned with the central inner ring of the annular gasket, and the two lifting racks 32 are sleeved on the left and right inner sides of the sub-bracket 2 and fixed by the fixing buckle 33, so that the lifting rack 32 can slide on the sub-bracket 2, and then the failed gasket is lifted up through the oil-proof lifter 1 by rotating the handle 6. The oil-proof lifter 1 first contacts the surface of the gasket, and performs a slight scraping action through its uniquely designed wedge-shaped or curved blade to gently and effectively remove grease, oil or other contaminants attached to the surface of the gasket. The built-in sensor of the system monitors the contact state of the oil-proof lifter 1 and the gasket in real time, and feeds back data such as scraping force, friction force and contact angle. If it is detected that the oil is not completely removed or the scraping force is insufficient, the system will automatically adjust the pressure of the movable claw 10 and the contact angle of the oil-proof lifter 1 to ensure that the scraping effect reaches the best state. After the lifting is completed, the two limit pins 13 are removed, and the drive motor 7 is started to make the coupling 12 and the screw 11 The fixed baffle plate 15 is driven downward to extend and retract in the upper linear bearing 4, and the connecting triangle block 31 is used to drive the two lifting racks 32 to slide downward, driving the four rotating gears 92 to rotate. The rotating gears 92 on both sides rotate in opposite directions, and the rotating gears 92 drive the upper movable claws 10 to rotate back and forth to open. When the opening state is appropriate, the movable claws 10 accurately fit the surface of the gasket that has been cleaned of grease, and perform stable and firm clamping to ensure that it will not slip or fail to grasp due to oil stains during the grasping and extraction process. The annular gasket is grasped by sensing the force of different weights. The sensor will also automatically adjust the grasping force of the movable claws 10 according to the friction force data to ensure that the grasping force is both strong enough and will not be over-clamped to cause damage to the gasket. The driving motor 7 stops running adaptively, and then the limit pin 13 is inserted into the pin hole. The annular gasket is safely and quickly taken out by rotating the handle 6. After taking it out, the latch is pulled out, and the screw rod 11 is restored. The gasket can be taken out and placed in the waste area, and a new annular gasket can be replaced and placed therein to complete quick replacement;

[0042] In addition, the system has an abnormal monitoring and adaptive protection mechanism. If an abnormal load is detected during scraping or grabbing (such as excessively thick oil or an abnormally increased gripping force), the system will immediately stop the movement of the active claw 10 and sound an alarm to avoid malfunctions caused by uncleaned oil or excessive clamping. This dynamic feedback mechanism ensures that the coordinated work of the oil-proof sheet 1 and the active claw 10 can always remain efficient and accurate, providing a safe and reliable guarantee for the automatic replacement of gaskets under complex working conditions. At the same time, in a complex environment of high temperature, high humidity and high pollution, the oil-proof sheet 1 can still maintain stable cleaning performance, ensuring the normal operation of the equipment under extreme working conditions.

[0043] Embodiment 2

[0044] Reference Figure 6 and Figure 7 , which is the second embodiment of the present invention.

[0045] In this embodiment, preferably, the drive motor 7 is installed on the upper surface of the rotating handle 6, and a coupling 12 is arranged between the drive motor 7 and the screw rod 11 to facilitate the rotation of the screw rod 11. The motor system carried by the drive motor 7 has an overload protection function. Once an abnormal load occurs during operation, the drive motor 7 will automatically stop running to prevent equipment damage or personal injury.

[0046] In this embodiment, preferably, two limit pins 13 are vertically arranged on the screw rod 11 and are respectively located below the coupling 12 and above the upper linear bearing 4 , so as to limit the position of the screw rod 11 .

[0047] In this embodiment, preferably, a countersunk bolt 16 is arranged between the oil-proof flap 1 and the sub-bracket 2, and the oil-proof flap 1 includes a flap tip 14 arranged on the side, and the angle between the inclined surface of the flap tip 14 and the horizontal direction is smaller than the angle between the inclined surface of the oil-proof flap 1 and the horizontal direction, so as to better scrape the grease on the surface of the annular gasket.

[0048] In this embodiment, preferably, the upper end of the sub-bracket 2 is U-shaped, which is convenient for connecting the triangular block 31 for lifting and lowering, and the lower end of the sub-bracket 2 is triangular. The triangle is convenient for installing the oil-proof warping piece 1 and for the tip of the oil-proof warping piece 1 to extend to the bottom of the annular gasket to scrape the lubricating oil.

[0049] Embodiment 3

[0050] This embodiment is obtained by combining the first embodiment and the second embodiment.

[0051] When in use, first use the oil-proof sheet 1 to scrape the grease on the surface of the annular gasket. After processing, the limit pin 13 is removed, and the driving motor 7 drives the screw rod 11 to move downward. The screw rod 11 drives the movable rack component 3 to move, drives the gear component 9 meshing with it to work, and drives the two sets of movable claws 10 to rotate to grab the annular gasket.

[0052] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
