[0024] 1. The present invention provides an overload protection mechanism. When the tilt sensor detects that the lifting frame is tilted or the pressure sensor detects that the load force between the main chain plates is too large, the information will be transmitted to the controller. The controller will then energize the electromagnetic block, causing it to generate magnetic force and attract the rubidium magnetic plate, causing the insertion column to disengage from the insertion slot and the insertion block, and the traction chain mechanism to disengage from the support arm, cutting off power transmission and protecting the traction chain unit and the drive motor from damage.

[0025] 2. The present invention is provided with a hydraulic pressure. When the overload protection mechanism is working, the hydraulic pressure will extend the telescopic rod and drive the cross block to enter the cross slot of the rotating rod, thereby limiting the rotating rod from reversing due to the separation of the traction chain mechanism from the support arm. At the same time, at the moment of separation, the blocking layer and the buffer pad at the bottom will prevent the bottom of the traction chain mechanism from being thrown upward, avoiding collision with other components, causing damage to the equipment and injury to personnel.

[0026] 3. The present invention provides a coating mechanism. When the placement block moves to the top of the gear and approaches the top magnetic block, the top magnetic block attracts the magnetic plate in the inner block, thereby compressing the telescopic spring and separating the retaining plate from the liquid outlet. The lubricating liquid in the placement block can flow out of the liquid outlet and adhere to the gear, greatly reducing the friction and impact between the primary and secondary chain plates and with the gear, ensuring that all parts of the chain are always in a good lubrication state, and further extending the service life.

[0027] 4. The present invention provides a brushing mechanism, and the servo motor 2 also drives the reciprocating screw to rotate, so that the moving block moves back and forth along the reciprocating screw, thereby driving the soft brush to brush the lubricating liquid on the gear, so that it is evenly attached to the gear, and the lubricating liquid can also adhere to the slots on the primary chain plate and the secondary chain plate.

[0028] 5. Servo motor 2 will control the moving block to move under the dustproof plate to prevent dust and impurities from falling onto the soft brush. At the same time, the rotating handle can be used to drive the rotating shaft and the sweep rod to rotate, and the sweep rod can be used to hit the soft brush to separate the excess softening liquid on the soft brush to prevent the softening liquid from adhering to the soft brush for a long time and causing corrosion to the soft brush. It can also sweep away dust and impurities that fall onto the soft brush during work to prevent these impurities from subsequently adhering to the gears and increasing the friction between the gears and the traction chain mechanism.

[0040] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0041] Example 1: Use Figures 1-10 A description will be given below of a traction member for a telescopic arm of a stacker according to an embodiment of the present invention.

[0042] like Figure 1-Figure 2 As shown, the traction member for the telescopic arm of a stacker of the present invention includes a traction body 1, the bottom of the traction body 1 is fixedly connected to a mounting plate 2 with a threaded hole 3 on the top, which is used for installation on the stacker, and further includes:

[0043] A traction unit 4 provided on the traction body 1, a brushing unit 8 for brushing the traction unit 4, and a traction frame unit 9 for moving up and down with the help of the traction unit 4;

[0044] When the present invention is working, the object to be lifted needs to be placed on the traction frame unit 9 first, and then the traction unit 4 will drive the traction frame unit 9 to move. During this process, the brush unit 8 will brush the traction unit 4 to increase the stability of the operation.

[0045] like Figure 4 As shown, the traction frame unit 9 includes a support plate 91, a guide rod 92 is symmetrically provided on the top of the support plate 91, and a lifting plate 93 is slidably connected to the outer surface of the guide rod 92. A lifting frame 94 for placing items is provided on one side of the lifting plate 93, and a tilt sensor 95 is provided on the lifting frame 94. An overload protection mechanism 96 is provided on the side of the lifting plate 93 away from the lifting frame 94;

[0046] The object is placed on the lifting frame 94. If the tilt sensor 95 detects that the lifting frame 94 is tilted, the overload protection mechanism 96 will start to work.

[0047] like Figure 5 As shown, the overload protection mechanism 96 includes a support arm 961 provided with an insertion slot 967. A second support plate 962 is fixedly connected to the outer surface of the support arm 961. A controller 963 is provided at one end of the second support plate 962. An electromagnetic block 964 is provided on the controller 963. An insertion post 965 is placed in the insertion slot 967. A nebulized magnetic plate 966 is fixedly connected to the end of the insertion post 965 near the electromagnetic block 964.

[0048] When the electromagnetic block 964 generates magnetic force, it will attract the rubidium magnetic plate 966.

[0049] When the tilt sensor 95 detects that the lifting frame 94 is tilted or the pressure sensor 465 detects that the load force between the main chain plates 461 is too large, the information will be transmitted to the controller 963. The controller 963 will then energize the electromagnetic block 964, causing it to generate magnetic force and attract the rubidium magnetic plate 966, causing the insertion column 965 to disengage from the insertion slot 967 and the insertion block 47, causing the traction chain mechanism 46 to disengage from the support arm 961, cutting off power transmission, and protecting the traction chain unit and the drive motor from damage.

[0050] The outer surface of the support plate 1 91 is fixedly connected to the bottom of the traction body 1 , and one end of the support arm 961 is fixedly connected to the outer surface of the lifting plate 93 .

[0052] During the movement of the traction unit 4, the cleaning sponge 7 will come into contact with the primary chain plate 461 and the secondary chain plate 462 in the traction unit 4, and clean off the attached dust and impurities, reducing the friction between the primary chain plate 461 and the secondary chain plate 462 and the gear 43.

[0053] The cleaning sponge 7 is slidably connected to the traction unit 4 .

[0054] The specific workflow is as follows:

[0055] During operation, after the object to be lifted is placed into the lifting frame 94, the traction unit 4 will drive the lifting plate 93 to move. At the beginning of this process, if the tilt sensor 95 detects that the lifting frame 94 is tilted or the pressure sensor 465 detects that the load force between the main chain plates 461 is too large, the information will be transmitted to the controller 963. The controller 963 will energize the electromagnetic block 964, so that it generates magnetic force and absorbs the rubidium magnetic plate 966, so that the insertion column 965 is disengaged from the insertion slot 967 and the insertion block 47, and the traction chain mechanism 46 is disengaged from the support arm 961, cutting off the power transmission and protecting the traction chain unit and the drive motor from damage.

[0056] Example 2: Use Figures 1-10 A description will be given below of a traction member for a telescopic arm of a stacker according to an embodiment of the present invention.

[0058] The traction unit 4 further includes:

[0059] Side grooves 45 are provided on both sides of the traction body 1. A support rod 48 is provided on the top of the traction body 1. One end of the support rod 48 is fixedly connected to a top magnetic block 49.

[0060] A hydraulic press 411 is provided on the side of the traction body 1 close to the cross slot 410 . A telescopic rod 412 is provided on the hydraulic press 411 . The output end of the telescopic rod 412 is fixedly connected to a cross positioning block.

[0061] While the overload protection mechanism 96 is working, the hydraulic machine 411 will extend the telescopic rod 412 and drive the cross block 413 to enter the cross slot 410 of the rotating rod 42, thereby limiting the rotating rod 42 from reversing due to the separation of the traction chain mechanism 46 from the support arm 961. At the same time, at the moment of separation, the blocking layer 5 and the buffer pad 6 at the bottom will prevent the bottom of the traction chain mechanism 46 from being thrown upward, avoiding collision with other components, causing damage to the equipment and injury to personnel.

[0062] The outer surface of the servo motor 41 is fixedly connected to the inner wall of the traction body 1 , and both sides of the counterweight block 44 are slidably connected to the inner wall of the side groove 45 .

[0063] The servo motor 41 drives the rotating rod 42 to rotate, thereby driving the gear 43 to rotate, and the traction chain mechanism 46 engaged with the gear 43 is also driven to move, and finally the lifting platform with the object placed thereon moves up and down along the guide rod 92.

[0064] like Figure 8 As shown, the traction chain mechanism 46 includes a main chain plate 461, a secondary chain plate 462, and a pin 463. The main chain plate 461, the secondary chain plate 462, and the pin 463 are connected and combined to form a chain traction. The main chain plate 461 and the secondary chain plate 462 are both provided with a slot 464 that matches the gear 43. The main chain plate 461 is provided with a pressure sensor 465. A tension rope 466 is provided between two adjacent pressure sensors 465. The main chain plate 461 is also provided with a coating mechanism 467.

[0065] The pressure sensor 465 reacts to the load force between the main link plates 461 by detecting the tension of the tension rope 466 .

[0066] like Figure 9 As shown, the coating mechanism 467 includes a placement block 4671, the outer surface of the placement block 4671 is fixedly connected to a liquid outlet 4672, lubricating liquid is stored in the placement block 4671, the inner wall of the placement block 4671 is fixedly connected to an inner block 4673, a telescopic spring 4674 is provided in the inner block 4673, one end of the telescopic spring 4674 is fixedly connected to a magnetic disk 4675 that attracts the top magnetic block 49, the side of the magnetic disk 4675 away from the telescopic spring 4674 is fixedly connected to a support column 4676, and the end of the support column 4676 away from the magnetic disk 4675 is fixedly connected to a baffle 4677.

[0067] When the placement block 4671 moves to the top of the gear 43 and approaches the top magnetic block 49, the top magnetic block 49 will attract the magnetic plate in the inner block 4673, thereby compressing the telescopic spring 4674 and causing the retaining plate 4677 to separate from the liquid outlet 4672, so that the lubricating fluid in the placement block 4671 can flow out from the liquid outlet 4672 and adhere to the gear 43, greatly reducing the friction and impact between the primary and secondary chain plates 462 and with the gear 43, ensuring that all parts of the chain are always in a good lubricated state, and further extending the service life.

[0068] The outer surface of the placement block 4671 is fixedly connected to the outer surface of the main chain plate 461 , and the elastic force of the telescopic spring 4674 causes the abutment plate 4677 to abut against the liquid outlet 4672 .

[0069] like Figure 10 As shown, the brushing unit 8 includes a servo motor 2 81, the output end of the servo motor 2 81 is fixedly connected to a reciprocating screw 82, the outer surface of the reciprocating screw 82 is threadedly connected to a moving block 84, the top of the moving block 84 is provided with a placement table 85, and the top of the placement table 85 is evenly provided with soft brushes 86, the end of the reciprocating screw 82 away from the servo motor 2 81 is rotatably connected to a support plate 3 83, the top of the support plate 3 83 is fixedly connected to a dustproof plate 87, the inner wall of the support plate 3 83 is rotatably connected to a rotating shaft 88, the outer surface of the rotating shaft 88 is fixedly connected to a sweeping rod 89, and the end of the rotating shaft 88 away from the sweeping rod 89 is fixedly connected to a handle 810.

[0070] When the gear 43 is driven to rotate, the servo motor 2 81 will also drive the reciprocating screw 82 to rotate, so that the moving block 84 moves back and forth along the reciprocating screw 82, thereby driving the soft brush 86 to brush the lubricating liquid on the gear 43, so that it is evenly attached to the gear 43, and the lubricating liquid can also be attached to the card groove 464 on the primary chain plate 461 and the secondary chain plate 462. At the same time, after use is completed, the servo motor 2 81 will control the moving block 84 to move under the dustproof plate 87 to prevent dust and impurities from falling onto the soft brush 86. At the same time, the rotating handle 810 can be used to drive the rotating shaft 88 and the sweeping rod 89 to rotate, and the sweeping rod 89 can be used to hit the soft brush 86 to separate the excess softening liquid on the soft brush 86, so as to prevent the softening liquid from being attached to the soft brush 86 for a long time and causing corrosion to the soft brush 86. It can also sweep away dust and impurities that fall on the soft brush 86 during work, so as to prevent these impurities from subsequently adhering to the gear 43, thereby increasing the friction between the gear 43 and the traction chain mechanism 46.

[0071] The second servo motor 81 is arranged on the outer surface of the traction body 1 , and the side of the third support plate 83 away from the reciprocating screw rod 82 is fixedly connected to the outer surface of the traction body 1 .

[0072] The specific workflow is as follows:

[0073] During operation, when the overload protection mechanism 96 is working, the hydraulic device 411 will extend the telescopic rod 412 and drive the cross block 413 to enter the cross slot 410 of the rotating rod 42, thereby limiting the rotating rod 42 from reversing due to the separation of the traction chain mechanism 46 from the support arm 961. When the stacker needs to lift an object, the servo motor 41 will drive the rotating rod 42 to rotate, thereby driving the gear 43 to rotate, and the traction chain mechanism 46 meshing with the gear 43 will also be driven to move, and finally the lifting platform with the objects placed thereon will move up and down along the guide rod 92. In this process, when the placement block 4671 moves to the top of the gear 43 and approaches the top magnetic block 49, the top magnetic block 49 will attract the magnetic plate in the inner block 4673, thereby compressing the telescopic spring 4674 and causing the baffle plate 4677 to separate from the liquid outlet 4672. , so that the lubricating liquid in the placement block 4671 can flow out from the liquid outlet 4672 and adhere to the gear 43. At the same time, the servo motor 2 81 will also drive the reciprocating screw 82 to rotate, so that the moving block 84 moves back and forth along the reciprocating screw 82, thereby driving the soft brush 86 to brush the lubricating liquid on the gear 43, so that it is evenly attached to the gear 43, so that the lubricating liquid can also adhere to the slots 464 on the primary chain plate 461 and the secondary chain plate 462.
