DETAILED DESCRIPTION

[0035] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] Embodiment 1, as Figure 1-Figure 11As shown, an energy-saving reciprocating telescopic mechanical arm fork lifting machine comprises a lifting assembly 1, a telescopic mechanical arm fork assembly 2 is fixedly installed on the front of the lifting assembly 1, the telescopic mechanical arm fork assembly 2 comprises a mounting plate 21, the mounting plate 21 is fixedly installed on the lifting assembly 1, four sets of slide rails 22 are welded on the front of the mounting plate 21, the insides of the four sets of slide rails 22 are all slidably connected with lifting sliders 25, the tops of the four sets of slide rails 22 are all fixedly installed with lifting hydraulic cylinders 23, the lifting hydraulic cylinders 23 provide lifting driving force for the lifting sliders 25, a rotating shaft is rotatably installed between the two sets of lifting sliders 25 on the same side, a first plug rod 26 is fixedly installed on the rotating shaft, a second plug rod 27 is hinged at the bottom of the first plug rod 26, and a torsion spring 266 is provided at the hinge;

[0037] A guide groove 1 261 is provided on both sides of the first plug rod 26, a guide groove 271 is provided on both sides of the second plug rod 27, and a tooth groove 262 is provided on the inner walls of the left guide groove 1 261 and the second guide groove 271. A driving plate 28 is provided between the first plug rod 26 and the second plug rod 27, and guide blocks 281 are rotatably installed at the four corners of the driving plate 28. The four groups of guide blocks 281 are respectively slidably connected in the guide groove 1 261 and the guide groove 2 271. Driving wheels 282 are rotatably installed inside the two groups of guide blocks 281 on the left side, and the driving wheels 282 are meshed with the tooth groove 262. Driving motors 283 are fixedly installed on the outer sides of the two groups of guide blocks 281 on the left side, and the driving motors 283 provide power for the driving wheels 282. A reset hydraulic cylinder 286 is fixedly installed on the end of the driving plate 28 close to the second plug rod 27;

[0038] A connecting piece 263 is slidably connected inside the right guide groove 1 261 , and a connecting slot 272 is formed at one end of the right guide groove 271 close to the first plug rod 26 . When the first plug rod 26 and the second plug rod 27 are horizontal, the connecting piece 263 can be inserted into the connecting slot 272 .

[0039] When forking the goods, the lifting hydraulic cylinder 23 is controlled to operate, and the lifting hydraulic cylinder 23 drives the lifting slide block 25 to descend. The lifting slide block 25 drives the first plug rod 26 to descend through the rotating shaft. At the same time, the rotating shaft rotates relative to the lifting slide block 25, and the rotating shaft drives the first plug rod 26 to rotate upward. In this embodiment, the driving source of the rotating shaft can be a rotating driving source such as a motor. At the same time, the upper driving motor 283 is energized, and the driving motor 283 drives the driving wheel 282 to rotate. The upper driving wheel 282 drives the upper guide block 281 to slide downward along the guide groove 1 261 under the action of the tooth groove 262. Therefore, the driving pull plate 28 will push the second plug rod 27 to swing downward relative to the first plug rod 26, so that the second plug rod 27 can be at the same A horizontal plane is extended and retracted horizontally, and the second plug rod 27 will not produce vertical displacement, and can be smoothly inserted into the pallet at the bottom of the cargo, so that the second plug rod 27 can be extended and retracted like a mechanical arm, and the vertical displacement of the first plug rod 26 is converted into the horizontal displacement of the second plug rod 27. Since the fork lift has sufficient vertical space, but the horizontal space is limited by its size, the present invention can greatly increase the fork distance without increasing the volume of the equipment, reduce the conveyor docking on each floor, and reduce the lifting cost. In addition, since the driving pull plate 28, the second plug rod 27 and the first plug rod 26 form a triangle, the overall fork strength of the telescopic mechanical arm fork assembly 2 can be improved, and the lifting of heavy objects is more stable;

[0040] When it is necessary to fork lighter cargo, the second insertion rod 27 and the first insertion rod 26 are extended to the horizontal at the same time, and the driving plate 28 is covered on the second insertion rod 27 and the first insertion rod 26. Fig.10In the state shown, the connecting piece 263 is controlled to slide into the connecting slot 272 at the same time. In this embodiment, there is no restriction on the driving of the connecting piece 263, and it can be any common linear drive. At this time, the second plug rod 27 is horizontally locked with the first plug rod 26, and then the two sets of driving motors 283 are controlled to be energized at the same time. The two sets of driving motors 283 drive the driving pull plate 28 to move in the direction of the goods, and the driving pull plate 28 is inserted into the tray at the bottom of the goods. Then, the driving pull plate 28 drives the goods to move onto the first plug rod 26. When the driving pull plate 28 drives the guide block 281 to slide out of the guide groove 271, the goods are completely moved to the first plug rod 26. Then the connecting piece 263 is controlled to slide out of the connecting slot 272. At this time, the torsion spring Under the action of 266, the second plug rod 27 swings upward and bends back to the first plug rod 26, pressing the goods on the first plug rod 26, without the need to additionally tie the goods, to ensure that the light goods will not fall during lifting; when the light goods are transported to the designated floor, the reset hydraulic cylinder 286 is controlled to extend, and the reset hydraulic cylinder 286 pushes the second plug rod 27 flat, so that the driving pull plate 28 can smoothly transport the goods down, and then the driving pull plate 28 is moved between the first plug rod 26 and the second plug rod 27. When the lifting slider 25 is controlled to rise, the rotating shaft is controlled to reverse, and at the same time, only the upper driving motor 283 is controlled to be energized, so as to ensure that an angle is formed between the first plug rod 26 and the second plug rod 27, but the second plug rod 27 can only be extended and retracted horizontally.

[0041] Embodiment 2, based on the above embodiment, provides a lifting assembly 1 structure;

[0042] like Figure 1 , Figure 2 As shown, the lifting assembly 1 includes a frame 11, a lifting plate 12 is slidably connected to the outer side of the frame 11, a mounting plate 21 is fixedly installed on the front side of the lifting plate 12, a guide column 13 is arranged inside the frame 11, a counterweight block 14 is slidably connected to the outer side of the guide column 13, a lifting motor 17 is fixedly installed on the top of the frame 11, a sprocket 15 is rotatably installed on the top of the frame 11, the lifting motor 17 provides power for the sprocket 15, the lifting plates 12 are connected through a transmission chain 16, and the transmission chain 16 changes the transmission direction through the sprocket 15.

[0043] Furthermore, four groups of sprockets 15 and transmission chains 16 are provided.

[0044] The lifting motor 17 is powered on, the lifting motor 17 drives the sprocket 15 to rotate, the sprocket 15 drives the lifting plate 12 to rise and fall through the transmission chain 16, and at the same time, the balancing weight of the counterweight block 14 rises and falls synchronously with the lifting plate 12 in the opposite direction, and the lifting effect is good.

[0045] Embodiment 3, based on the above embodiment, further includes: a driving wheel 251 is rotatably installed on the inner side of the lifting slider 25, a driven wheel 252 is fixedly installed on the outer side of the rotating shaft, the driven wheel 252 is meshed with the driving wheel 251, and a tooth groove 24 is opened on the outer side of the mounting plate 21, and the driving wheel 251 is meshed with the tooth groove 24.

[0046] When forking the goods, the lifting hydraulic cylinder 23 is controlled to operate, and the lifting hydraulic cylinder 23 drives the lifting slide block 25 to descend. The lifting slide block 25 drives the first plugging rod 26 to descend through the rotating shaft. At the same time, the lifting slide block 25 drives the driving wheel 251 to descend relative to the tooth groove 1 24. The driving wheel 251 rotates under the action of the tooth groove 1 24, and then the driving wheel 251 drives the driven wheel 252 to rotate, and the driven wheel 252 drives the rotating shaft to rotate. Under the reversing action of the driven wheel 252, the rotating shaft drives the first plugging rod 26 to swing upward. No additional drive is required, the structure is compact, and at the same time, it can ensure that the first plugging rod 26 will not change arbitrarily during lifting and lowering, and the control is stable.

[0047] Embodiment 4, on the basis of the above embodiment, further includes: a storage hole is opened inside the upper right guide block 281, a tension spring 3 284 is fixedly installed inside the storage hole, a hanging plate 285 is fixedly installed on the outer side of the tension spring 3 284, a sliding groove is opened at the bottom end of the right guide groove 1 261, a connecting member 263 is slidably connected in the sliding groove, a tension spring 1 264 is arranged between the connecting member 263 and the inner wall of the sliding groove, a hook 265 is arranged on the outer side of the connecting member 263, and the hanging plate 285 can be hung on the hook 265.

[0048] When it is necessary to fork lighter cargo, the second insertion rod 27 and the first insertion rod 26 are extended to the horizontal at the same time, and the driving plate 28 is covered on the second insertion rod 27 and the first insertion rod 26. Fig.10 In the state shown, under the restriction of the driving plate 28, the second plug rod 27 will not swing upward. When the upper right guide block 281 drives the hanging plate 285 to move to the position of the connecting member 263, the hanging plate 285 is hung on the hook 265. When the upper right guide block 281 is separated from the guide groove 261, the hanging plate 285 drives the connecting member 263 to be inserted into the connecting slot 272. The first plug rod 26 and the second plug rod 27 are horizontally locked together, restricting the second plug rod 27 from swinging upward, so that the driving plate 2 8 can stably fork the goods. When the driving pull plate 28 forks the goods, the tension spring 274 is stretched. When the driving pull plate 28 drives the upper guide block 281 to slide into the guide groove 261, the hanging plate 285 is separated from the hook 265, and the tension spring 264 drives the connecting member 263 away from the connecting slot 272. When the driving pull plate 28 is completely separated from the second plug rod 27, the second plug rod 27 can swing upward. Therefore, through the arrangement of this embodiment, there is no need to set a driving source for the connecting member 263, and the structure is compact.

[0049] Embodiment five, on the basis of the above embodiment, further includes: two sets of telescopic grooves are opened at one end of the second plug rod 27 away from the first plug rod 26, and the inside of the telescopic groove is slidably connected with a telescopic rod 273, and a tension spring 274 is arranged between the telescopic rod 273 and the inner wall of the telescopic groove, and a fork head 275 is fixedly installed on the front side of the telescopic rod 273, and guide grooves 3 276 are opened on both sides of the fork head 275, and the guide block 281 can slide into the guide groove 3 276.

[0050] Furthermore, the fork head 275 is triangular in design.

[0051] When the driving plate 28 drives the lower guide block 281 to insert into the guide groove three 276, as the driving plate 28 continues to move, the driving plate 28 drives the fork head 275 to extend, further increasing the cargo forking distance, and through the setting of the fork head 275, it is more convenient to insert the second insertion rod 27 into the cargo pallet.

[0052] Embodiment 6, based on the above embodiment, further includes that the upper surface of the driving pull plate 28 is provided with friction teeth to improve the cargo transportation stability of the driving pull plate 28.
