[0027] This invention provides a quick replacement device for electric linear actuators, such as... Figure 1-9 As shown, the device includes a sleeve 1, a movable column 2, and a housing 3. The sleeve 1 communicates with the housing 3, and the movable column 2 is movably inserted into the sleeve 1. It also includes a guide slide 18, multiple upper-mounting mechanisms 16, a disassembly assembly 13, a transmission belt 10, and two drive mechanisms 6. The guide slide 18 is vertically arranged on one inner wall of the housing 3, and the two drive mechanisms 6 are symmetrically arranged within the housing 3. The transmission belt 10 is fitted onto the two drive mechanisms 6 and contacts the movable column 2. The disassembly assembly 13 is located on the other inner wall of the housing 3 and is adapted to the upper-mounting mechanism 16.
[0028] The drive mechanism 6 includes a linkage belt 9, a main rotating wheel 29, a first connecting cover 14, and a second connecting cover 15. The main rotating wheel 29 is pivotally connected inside the housing 3 and is in contact with the inner side of the transmission belt 10. The first connecting cover 14 is coaxially connected to the transmission belt 10, and the second connecting cover 15 is detachably snapped onto the side of the transmission belt 10 away from the first connecting cover 14.
[0029] It also includes two motors 5 and telescopic rods 4. The two motors 5 are symmetrically arranged inside the housing 3. The two telescopic rods 4 are respectively located on the output ends of the two motors 5, and the movable ends of the telescopic rods 4 are connected to the connecting cover 15.
[0030] It also includes a main motor 19 and a support base 7. Both the support base 7 and the main motor 19 are housed inside the housing 3, with the support base 7 located between the two main rotating wheels 29. The output end of the main motor 19 is connected to the connecting cover 14, and the movable column 2 has multiple openings 8.
[0031] It also includes multiple toothed seats 28, which are detachably snapped onto the transmission belt 10 at equal intervals. The top of the toothed seat 28 has a slot 26, and the side of the toothed seat 28 has a side slot 27. The side slot 27 communicates with the slot 26.
[0032] The disassembly assembly 13 includes an annular slide 12 and multiple linkage components 11. The annular slide 12 corresponds to the transmission belt 10, and the multiple linkage components 11 are slidably engaged on the annular slide 12. The multiple linkage components 11 correspond one-to-one with multiple gear seats 28.
[0033] The linkage assembly 11 includes a sliding motor 25, an electromagnet 21, an auxiliary telescopic rod 24, and a locking connector 23. The sliding motor 25 is slidably fitted onto the annular slide rail 12, and the auxiliary telescopic rod 24 is located at the output end of the sliding motor 25. The locking connector 23 is located at the movable end of the auxiliary telescopic rod 24 and is detachably engaged with the side slot 27. The movable end of the auxiliary telescopic rod 24 corresponds to the slot 26. The electromagnet 21 is located at the movable end of the auxiliary telescopic rod 24.
[0034] The upper structure 16 includes a snap-fit slider 17, a drive motor 20, a snap-fit connector 23, and an auxiliary telescopic rod 22. The snap-fit slider 17 is detachably snapped into the linkage belt 9, and the drive motor 20 is mounted on the snap-fit slider 17. The auxiliary telescopic rod 22 is mounted on the output end of the drive motor 20, and the snap-fit connector 23 is mounted on the auxiliary telescopic rod 22.
[0035] Working principle: In use, the main motor 19 first works, driving the main rotating wheel 29 to rotate. Then the transmission belt 10 rotates, causing the toothed seat 28 to mesh with the opening 8, thereby allowing the movable column 2 to extend or retract from the sleeve 1.
[0036] When a toothed seat 28 needs to be replaced or repaired, first reduce the speed of the main motor 19. When the damaged toothed seat 28 moves to the higher side, retract the telescopic rod 4 to disengage the connecting cover 15 from the main rotating wheel 29. This way, the connecting cover 15 does not need to rotate with the main rotating wheel 29. Then, insert the upper mechanism 16, which contains the new toothed seat 28, into the guide slide 18. Next, the locking slider 17 on the upper mechanism 16 engages with the linkage belt 9. Then, as the motor 5 rotates, make the moving speed of the upper mechanism 16 match the moving speed of the toothed seat 28. At the same time, the linkage component 11 set on the damaged toothed seat 28 magnetically connects the electromagnet 21 to the auxiliary telescopic rod 22 via the auxiliary telescopic rod 24. Then, retract the auxiliary telescopic rod 24, forcing the toothed seat 28, which was originally on the transmission belt 10, to slide off the transmission belt 10, while simultaneously engaging the new toothed seat 28 with the transmission belt 10. This process is still completed on the part of the transmission belt 10 away from the movable column 2. Simultaneously, rotate the locking connector 23 on the auxiliary telescopic rod 24 to disengage the replaced gear seat 28 from the linkage assembly 11, while the auxiliary telescopic rod 22 repeats the disengagement operation. At this time, by reducing the speed of the motor 5, personnel can successfully remove the replaced upper structure 16 from the housing 3. This effectively facilitates personnel to perform multiple repairs and replacements of the gear seats 28.
[0037] In summary, this electric push rod quick replacement device, through the coordinated operation of the guide slide 18, multiple upper assembly mechanisms 16, disassembly assembly 13, transmission belt 10, and two drive mechanisms 6, enables the device to match and align the teeth on the chain belt. Furthermore, during disassembly, the motor can be removed and installed without stopping the motor, allowing for disassembly and installation of the teeth while the chain belt is running. This significantly improves work efficiency.
