Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to an empty basket recovery lifting device. Background Art

[0002] The empty basket recovery lifting device of the prior art has the following problems: when a steering gear is used for driving, the spiral rod lifting system has a high cost due to the large number of steering gears used. At the same time, the coupling may become loose during use, resulting in poor synchronization of the four spiral rods, affecting work efficiency; when a synchronous wheel is used for driving, the spiral rods must be lifted and lowered using four spiral rods of the same shape and with the same rotation direction.

The empty basket recovery lifting device includes a lifting system 10, a transmission system 20, a transmission system 30 and a quick release system 40.

[0030] like Figures 1A to 1CAs shown, the lifting system 10 includes a buffer roller 11 for the empty basket 50 to transition, a first lifting sensor 121, a second lifting sensor 122 and a third lifting sensor 123 for respectively sensing the real-time position of the empty basket 50, a lifting base 13 and a lifting mounting plate 14, the buffer roller 11 and the lifting mounting plate 14 are both arranged on the lifting base 13, the buffer roller 11 is arranged at the entrance of the lifting base 13, and the first lifting sensor 121, the second lifting sensor 122 and the third lifting sensor 123 are sequentially arranged on the lifting mounting plate 14 in a top-to-bottom order.

[0032] In detail, the transmission system 20 is composed of the transmission power member 21 and the first speed reducer 221 and the second speed reducer 222, which jointly drive the synchronous wheel and the synchronous belt to realize the synchronous operation of the first spiral rod 231, the second spiral rod 232, the third spiral rod 233 and the fourth spiral rod 234. The transmission power member 21 drives the first speed reducer 221 and the second speed reducer 222. The rotation directions of the output ends of the first speed reducer 221 and the second speed reducer 222 are opposite. The two synchronous wheels matched with the first speed reducer 221 respectively drive the second spiral rod 231, the second speed reducer 232, the third spiral rod 233 and the fourth spiral rod 234. The rod 232 and the first screw rod 231 make the first screw rod 231 and the second screw rod 232 rotate in the same direction. Similarly, the two synchronous wheels matched with the second reduction member 222 respectively drive the third screw rod 233 and the fourth screw rod 234, so that the third screw rod 233 and the fourth screw rod 234 rotate in the same direction, so that the second screw rod 232 and the fourth screw rod 234, the second screw rod 232 and the third screw rod 233, the fourth screw rod 234 and the first screw rod 231 rotate in symmetrical directions.

[0033] Further, the first screw rod 231, the second screw rod 232, the third screw rod 233 and the fourth screw rod 234 are fixed by each of the upper bearings 251 and each of the lower bearings 252, the synchronous belt between the first speed reducer 221 and the second screw rod 232 is tensioned by the first tensioning member 241, the synchronous belt between the first speed reducer 221 and the first screw rod 231 is tensioned by the fourth tensioning member 244, the synchronous belt between the second speed reducer 222 and the fourth screw rod 234 is tensioned by the third tensioning member 243, the synchronous belt between the second speed reducer 222 and the third screw rod 233 is tensioned by the second tensioning member 242, the second screw rod 232 and the fourth screw rod 234 are symmetrical in appearance, the fourth screw rod 234 and the first screw rod 231 are symmetrical in appearance, and the third screw rod 233 and the first screw rod 231 are symmetrical in appearance.

[0034] In detail, the transmission power member 21, the first deceleration member 221 and the second deceleration member 222 are fixedly arranged, and the transmission power member 21, the first deceleration member 221 and the second deceleration member 222 are combined and arranged on the deceleration fixed plate 27, and the deceleration fixed plate 27 is installed on the transmission mounting plate 26, and the ends of the output shafts of the first deceleration member 221 and the second deceleration member 222 are equipped with synchronous wheels, and the first tensioning member 241, the second tensioning member 242, the third tensioning member 243 and the fourth tensioning member 244 are arranged on the transmission mounting plate 26.

[0035] Furthermore, the transmission system 20 is fixed to the lifting base 13 via the transmission mounting plate 26 .

[0036] Furthermore, the transmission system 30 is disposed on the transmission mounting plate 26 through the spacer 28 .

[0037] In an actual application scenario, the initial position of the empty basket 50 just covers the spiral lines above the first spiral rod 231, the second spiral rod 232, the third spiral rod 233 and the fourth spiral rod 234. When the empty basket 50 from the front line passes through the buffer roller 11, it falls down due to inertia, and the empty basket 50 can be automatically stacked. When the empty baskets 50 are continuously conveyed to the subsequent line, each empty basket 50 is continuously stacked on the previous empty basket 50. When the stacking height of the empty baskets 50 reaches or exceeds the first lifting sensor 121, as shown in FIG. Figure 2 As shown, the transmission system 20 operates, the first screw rod 231, the second screw rod 232, the third screw rod 233 and the fourth screw rod 234 all rotate to start conveying the empty basket 50 downwards, and when the stacking height of the empty basket 50 is lower than the sensing height position of the second lifting sensor 122, the first screw rod 231, the second screw rod 232, the third screw rod 233 and the fourth screw rod 234 no longer continue to convey the basket downwards. There should always be one empty basket 50 at the sensing position of the third lifting sensor 123 to ensure that the empty basket 50 can be stacked normally later. When the third lifting sensor 123 has no sensing, the empty basket 50 cannot perform the falling action later, and the empty basket recovery lifting device is in an alarm state, notifying the staff to intervene in time. In detail, when the first spiral rod 231, the second spiral rod 232, the third spiral rod 233 and the fourth spiral rod 234 are symmetrically arranged, and the rotation directions of any two of the symmetrically arranged spiral rods are symmetrical, the empty basket 50 will be affected by the symmetrical component forces generated by the first spiral rod 231, the second spiral rod 232, the third spiral rod 233 and the fourth spiral rod 234 during the rotation of the first spiral rod 231, the second spiral rod 232, the third spiral rod 233 and the fourth spiral rod 234. The component forces cancel each other out, so that the empty basket 50 can remain in a relatively stable state during the descent.

[0038] like Figure 3As shown, the transmission system 30 includes a first transmission induction member 311, a second transmission induction member 312, one or more transmission rollers 32 and a transmission support plate 33. The first transmission induction member 311 and the second transmission induction member 312 are arranged on the side of the transmission support plate 33, and each of the transmission rollers 32 is evenly arranged on the transmission support plate 33. Each of the transmission rollers 32 is used to transport the empty basket 50. In an actual application scenario, when the first spiral rod 231, the second spiral rod 232, the third spiral rod 233 and the fourth spiral rod 234 rotate one circle, the empty basket 50 falls downward to the transmission system 30, and after the first transmission induction member 311 senses the empty basket 50, the transmission roller 32 starts to rotate, and transports the empty basket 50 to other docking lines, and transports the empty basket 50 out. When the second transmission induction member 312 has no induction, it means that the empty basket 50 has been output, and the transmission roller 32 stops rotating.

[0039] like Figures 4A to 4B As shown, the quick release system 40 includes a rotating shaft fixing member 41, a rotating shaft 42, a quick release fixing plate 43, a quick release clamp 44, a first limit member 451 and a second limit member 452, wherein the quick release fixing plate 43 of the quick release system 40 is fixed to the rotating shaft 42 through the rotating shaft fixing member 41, the quick release fixing plate 43 rotates around the rotating shaft 42, the lower bearing 252 and the upper bearing 251 are attached and installed on the quick release fixing plate 43, the rotating shaft fixing member 41 is arranged on the lifting base 13, the rotating shaft 42 is arranged on the quick release fixing plate 43, the upper bearing 251 and the lower bearing 252 are arranged on the quick release fixing plate 43, the quick release clamp 44 is arranged on the lifting base 13, and the first limit member 451 and the second limit member 452 are respectively arranged on the lifting mounting plate 14 and the transmission support plate 33. In actual application scenarios, after the quick-release fixing plate 43 is rotated, it is limited by the first limiting member 451 and the second limiting member 452. After the position of the quick-release fixing plate 43 is selected, the quick-release fixing plate 43 is fixed by the quick-release clamp 44. When the stuck empty basket 50 needs to be taken out, the quick-release fixing plate 43 can be rotated open by loosening the quick-release clamp 44, and the stuck empty basket 50 can be conveniently and quickly taken out.
