Technical Field

[0001] The present invention relates to the technical field of stacker traction, and specifically to a traction member for the telescopic arm of a stacker. Background Art

[0010] Preferably, the traction chain mechanism includes a main chain plate, a secondary chain plate and a pin shaft.

Slots adapted to the gear are arranged on both the main chain plate and the secondary chain plate. A pressure sensor is arranged on the main chain plate, a tension rope is arranged between adjacent two pressure sensors, and a coating mechanism is also arranged on the main chain plate; The pressure sensor detects the tension of the tension rope to reflect the load force between the main chain plates.

[0015] The beneficial effects of the present invention are as follows: 1. The present invention sets 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 energize the electromagnetic block to generate magnetic force and absorb the rubidium magnetic plate, so that the insertion column is separated from the insertion slot and the insertion block, the traction chain mechanism is separated from the support arm, and the power transmission is cut off, thereby protecting the traction chain unit and the drive motor from damage.

[0016] 2. The present invention is provided with a hydraulic device. When the overload protection mechanism is working, the hydraulic device will extend the telescopic rod and drive the cross block to enter the cross groove of the rotating rod, thereby limiting the reversal of the rotating rod 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.

[0017] 3. The present invention sets 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 baffle plate from the liquid outlet, so that the lubricating liquid in the placement block can flow out from the liquid outlet and adhere to the gear, which greatly reduces the friction and impact between the primary and secondary chain plates and the gears, ensuring that all parts of the chain are always in a good lubrication state, further extending the service life.

[0018] 4. The present invention sets a brushing mechanism, and the servo motor 2 will also drive 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 be attached to the slots on the main chain plate and the secondary chain plate.

[0019] 5. The second servo motor controls the moving block to move under the dust-proof board to prevent dust and impurities from falling onto the soft brush. At the same time, the rotating handle can drive the rotating shaft and the sweeping rod to rotate, and the sweeping rod hits the soft brush to separate the excess softening liquid on the soft brush, avoiding the corrosion of the soft brush caused by the long-term adhesion of the softening liquid on the soft brush. It can also sweep away the dust and impurities that fall onto the soft brush during the working process, preventing these impurities from adhering to the gear subsequently and increasing the friction between the gear and the traction chain mechanism.

Detailed implementation mode

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes. Embodiment 1, usage Figures 1 - 10 The traction member for the telescopic arm of the stacker of one embodiment of the present invention will be described as follows.

[0032] As Figures 1 - 2 shown, the traction member for the telescopic arm of the stacker of the present invention includes a traction main body 1. The bottom of the traction main body 1 is fixedly connected with a mounting plate 2 having threaded holes 3 provided at the top for mounting on the stacker. It further includes: a traction unit 4 provided on the traction main body 1, a brushing unit 8 for flat brushing the traction unit 4, and a traction frame unit 9 that moves up and down by means of the traction unit 4; When the present invention is working, first, the object to be lifted needs to be placed on the traction frame unit 9. Then, the traction unit 4 will drive the traction frame unit 9 to move. During this process, the brushing unit 8 will brush the traction unit 4 to increase the running stability.

[0033] As Figure 4 shown, the traction frame unit 9 includes a first support plate 91. Guide rods 92 are symmetrically arranged on the top of the first support plate 91. A lifting plate 93 is slidably connected to the outer surface of the guide rods 92. A lifting frame 94 for placing items is arranged on one side of the lifting plate 93. An inclination sensor 95 is arranged on the lifting frame 94. An overload protection mechanism 96 is arranged on the side of the lifting plate 93 away from the lifting frame 94. The object will be placed on the lifting frame 94. If the inclination sensor 95 detects that the lifting frame 94 is tilted, the overload protection mechanism 96 will start to work.

[0034] As Figure 5 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 arranged at one end of the second support plate 962. An electromagnet block 964 is arranged on the controller 963. An insertion column 965 is placed in the insertion slot 967. A rubidium magnetic plate 966 is fixedly connected to one end of the insertion column 965 close to the electromagnet block 964. When the electromagnet block 964 generates magnetic force, it will attract the rubidium magnetic plate 966.

[0035] After the inclination 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 electromagnet block 964, so that it generates magnetic force and adsorbs the rubidium magnetic plate 966, causing the insertion column 965 to disengage from the insertion slot 967 and the insertion block 47, and causing the traction chain mechanism 46 to disengage from the support arm 961, cutting off the power transmission and protecting the traction chain unit and the drive motor from damage.

[0036] The outer surface of the first support plate 91 is fixedly connected to the bottom of the traction main body 1. One end of the support arm 961 is fixedly connected to the outer surface of the lifting plate 93.

[0037] As Figure 3 shown, a resisting layer 5 is fixedly connected to the inner wall of the traction main body 1. A buffer pad 6 is arranged at the bottom of the resisting layer 5. A cleaning sponge 7 is arranged on the outer surface of the resisting layer 5. During the movement of the traction unit 4, the cleaning sponge 7 will come into contact with the main chain plate 461 and the sub-chain plate 462 in the traction unit 4 and clean off the attached dust and impurities, reducing the friction between the main chain plate 461 and the sub-chain plate 462 and the gear 43.

[0038] The cleaning sponge 7 is slidably connected to the traction unit 4.

[0039] The specific working process is as follows: During operation, after placing the object to be lifted into the lifting frame 94, the traction unit 4 drives 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 then energize the electromagnet 964, causing it to generate a magnetic force and attract the rubidium magnetic plate 966, so that the insertion column 965 disengages from the insertion slot 967 and the insertion block 47, disconnecting the traction chain mechanism 46 from the support arm 961, cutting off the power transmission, and protecting the traction chain unit and the drive motor from damage.

[0040] Example two, use Figures 1 - 10 The traction member for the telescopic arm of the stacker crane according to an embodiment of the present invention will be described as follows.

[0041] As Figures 6 - 7 shown, for the traction member for the telescopic arm of the stacker crane of the present invention, on the basis of Example one, the traction unit 4 includes a servo motor one 41. The output end of the servo motor one 41 is fixedly connected to a rotating rod 42. A cross groove 410 is provided at one end of the rotating rod 42 away from the servo motor one 41. The outer surface of the rotating rod 42 is fixedly connected to a gear 43. A traction chain mechanism 46 is engaged with the gear 43. One end of the traction chain mechanism 46 is fixedly connected to a counterweight 44. The end of the traction chain mechanism 46 away from the counterweight 44 is fixedly connected to an insertion block 47.

[0042] The traction unit 4 further includes: Side grooves 45 provided on both sides of the traction main body 1. A support rod one 48 is provided at the top of the traction main body 1. One end of the support rod one 48 is fixedly connected to a top magnetic block 49; A hydraulic device 411 provided on the side of the traction main body 1 close to the cross groove 410. A telescopic rod 412 is provided on the hydraulic device 411. The output end of the telescopic rod 412 is fixedly connected to a cross clamping block.

[0043] While the overload protection mechanism 96 is working, the hydraulic device 411 will extend the telescopic rod 412 and drive the cross clamping block 413 into the cross groove 410 of the rotating rod 42, thereby restricting the reverse rotation of the rotating rod 42 due to the disconnection of the traction chain mechanism 46 from the support arm 961. At the same time, at the moment of disconnection, the resisting layer 5 and the buffer pad 6 at the bottom will block the bottom of the traction chain mechanism 46 from being thrown up, avoiding collisions with other components, causing damage to the equipment and injuries to personnel.

[0044] The outer surface of the first servo motor 41 is fixedly connected to the inner wall of the traction main body 1, and both sides of the counterweight 44 are slidably connected to the inner wall of the side groove 45.

[0045] The first servo motor 41 drives the rotating rod 42 to rotate, thereby driving the gear 43 to rotate. 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.

[0046] As Figure 8 shown, the traction chain mechanism 46 includes a main chain plate 461, a secondary chain plate 462 and a pin shaft 463. The main chain plate 461, the secondary chain plate 462 and the pin shaft 463 are connected and combined to form a chain traction. Both the main chain plate 461 and the secondary chain plate 462 are provided with card slots 464 adapted to the gear 43. A pressure sensor 465 is provided on the main chain plate 461. A tension rope 466 is provided between two adjacent pressure sensors 465. A coating mechanism 467 is also provided on the main chain plate 461; The pressure sensor 465 detects the tension of the tension rope 466 to reflect the magnitude of the load force between the main chain plates 461.

[0047] As Figure 9 shown, the coating mechanism 467 includes a placement block 4671. The outer surface of the placement block 4671 is fixedly connected with a liquid outlet 4672. The placement block 4671 stores lubricating fluid. The inner wall of the placement block 4671 is fixedly connected with an inner block 4673. A telescopic spring 4674 is arranged in the inner block 4673. One end of the telescopic spring 4674 is fixedly connected with a magnetic disk 4675 that attracts the top magnet 49. The side of the magnetic disk 4675 away from the telescopic spring 4674 is fixedly connected with a support column 4676. One end of the support column 4676 away from the magnetic disk 4675 is fixedly connected with a resisting baffle 4677.

[0048] When the placement block 4671 moves to the top of the gear 43 and approaches the top magnet 49, the top magnet 49 attracts the magnetic plate in the inner block 4673, thereby compressing the telescopic spring 4674 and separating the resisting baffle 4677 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 main and secondary chain plates 462 and the gear 43, ensuring that all parts of the chain are always in a good lubricated state, and further extending the service life.

[0049] 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 makes the resisting baffle 4677 press against the liquid outlet 4672.

[0050] As Figure 10As shown, the brushing unit 8 includes a second servo motor 81. The output end of the second servo motor 81 is fixedly connected to a reciprocating lead screw 82. A moving block 84 is threadedly connected to the outer surface of the reciprocating lead screw 82. A placing table 85 is arranged on the top of the moving block 84. Soft brushes 86 are evenly arranged on the top of the placing table 85. One end of the reciprocating lead screw 82 away from the second servo motor 81 is rotatably connected to a third support plate 83. A dust-proof plate 87 is fixedly connected to the top of the third support plate 83. A rotating shaft 88 is rotatably connected to the inner wall of the third support plate 83. A sweeping rod 89 is fixedly connected to the outer surface of the rotating shaft 88. One end of the rotating shaft 88 away from the sweeping rod 89 is fixedly connected to a handle 810.

[0051] During the rotation of the gear 43, the second servo motor 81 also drives the reciprocating lead screw 82 to rotate, so that the moving block 84 moves back and forth along the reciprocating lead screw 82, driving the soft brush 86 to brush the lubricating liquid on the gear 43, making it evenly adhere to the gear 43, and enabling the lubricating liquid to also adhere to the card slots 464 on the main chain plate 461 and the secondary chain plate 462. At the same time, after use, the second servo motor 81 controls the moving block 84 to move under the dust-proof plate 87 to prevent dust and impurities from falling onto the soft brush 86. At the same time, the handle 810 can be rotated to drive the rotating shaft 88 and the sweeping rod 89 to rotate, and the sweeping rod 89 hits the soft brush 86 to separate the excess softening liquid on the soft brush 86, avoiding the corrosion of the soft brush 86 caused by the long-term adhesion of the softening liquid, and also sweeping away the dust and impurities that fall onto the soft brush 86 during the working process, preventing these impurities from adhering to the gear 43 subsequently and increasing the friction between the gear 43 and the traction chain mechanism 46.

[0052] The second servo motor 81 is arranged on the outer surface of the traction main body 1, and one side of the third support plate 83 away from the reciprocating lead screw 82 is fixedly connected to the outer surface of the traction main body 1.

[0053] The specific working process is as follows: During operation, while the overload protection mechanism 96 is working, the hydraulic actuator 411 will extend the telescopic rod 412 and drive the cross-shaped block 413 into the cross-shaped groove 410 of the rotating rod 42, thereby restricting the reverse rotation of the rotating rod 42 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. The traction chain mechanism 46 engaged with the gear 43 will also be driven to move, and finally the lifting platform with the object will move up and down along the guide rod 92. During this process, when the placement block 4671 moves to the top of the gear 43 and approaches the top magnet 49, the top magnet 49 will attract the magnetic plate in the inner block 4673, thereby compressing the telescopic spring 4674 and separating the blocking plate 4677 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 81 will also drive the reciprocating lead screw 82 to rotate, so that the moving block 84 moves back and forth along the reciprocating lead screw 82, thereby driving the soft brush 86 to brush the lubricating liquid on the gear 43 to make it evenly adhere to the gear 43, so that the lubricating liquid can also adhere to the card slots 464 on the main chain plate 461 and the secondary chain plate 462. After use, the servo motor 81 will control the moving block 84 to move under the dust-proof plate 87 to prevent dust and impurities from falling onto the soft brush 86. At the same time, the rotating handle 810 can be rotated to drive the rotating shaft 88 and the sweeping rod 89 to rotate, and the sweeping rod 89 will strike the soft brush 86 to separate and remove the excess softening liquid on the soft brush 86 and the dust and impurities that fall onto the soft brush 86 during work.
