[0028] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 and Figure 2 This embodiment provides a bidirectional drive translation lifting mechanism, including a first transmission chain 1, a second transmission chain 2 and a dual output shaft motor 3.

[0030] The first transmission chain 1 is used to drive the platform to rise and fall vertically. The first transmission chain 1 comprises at least one vertically arranged first elevator 11 and a first coupling mechanism for driving the output end of the first elevator 11 to rise and fall in the vertical direction.

[0031] It is worth mentioning that Figure 3 As shown, the vertical arrangement of the first lift 11 means that the output shaft of the first lift 11 can move in the vertical direction. In addition, the output shaft end of the first lift 11 is detachably connected to the platform to be driven.

[0032] Specifically, the first coupling mechanism includes a vertically arranged first transmission shaft 12 and a horizontally arranged second transmission shaft 13. The first end of the first transmission shaft 12 and the first end of the second transmission shaft 13 are connected via a first commutator 14 to transmit the rotation of the vertically arranged first transmission shaft 12 to the horizontally arranged second transmission shaft 13.

[0033] The second end of the second transmission shaft 13 is connected to the first elevator 11, so as to drive the first elevator 11 to work and realize the movement of the platform connected to the first elevator 11 in the vertical direction.

[0034] In a more preferred embodiment, the first commutator 11 is a 1-LR type commutator.

[0035] In order to enhance the stability of the vertical movement of the platform, there are two first elevators 11, which are symmetrically distributed on the left and right sides of the first commutator 14. The two first elevators 11 are connected to the left and right sides of the first commutator 14 via the second transmission shaft 13, respectively.

[0036] The second transmission chain 2 is used to drive the platform to translate horizontally. The second transmission chain 2 includes at least one second elevator 21 arranged horizontally and a second coupling mechanism used to drive the output end of the second elevator 21 to translate horizontally.

[0037] Similarly, if Figure 3 As shown, the horizontal arrangement of the second lift 21 means that the output shaft of the second lift 21 can move in the horizontal direction. In addition, the output shaft end of the second lift 21 is detachably connected to the platform to be driven.

[0038] It is worth mentioning that the first lift 11 and the second lift 21 can be connected to different platforms or the same platform. When connected to the same platform, in order to avoid interference in movement, when the first lift 11 is working, the connection between the second lift 21 and the platform should be disconnected, and vice versa.

[0039] Specifically, the second coupling mechanism includes a third transmission shaft 22 arranged horizontally and a fourth transmission shaft 23 arranged vertically. The second end of the third transmission shaft 22 and the first end of the fourth transmission shaft 23 are connected via a third commutator 25 to transmit the rotation of the third transmission shaft 22 arranged horizontally to the fourth transmission shaft 23 arranged vertically.

[0040] The second end of the fourth transmission shaft 23 is connected to the second elevator 21 , so as to drive the second elevator 21 to work and realize the movement of the platform connected to the second elevator 21 in the horizontal direction.

[0041] In order to enhance the stability of the horizontal movement of the platform, the number of the second elevators 21 is two, which are symmetrically distributed on the left and right sides of the first transmission shaft 12. The two second elevators 21 are connected to the left and right sides of the second commutator 24 via the fourth transmission shaft 23, the third commutator 25, and the third transmission shaft 22 respectively.

[0042] The dual-output shaft motor 3 includes a first output shaft and a second output shaft.

[0043] The first output shaft is connected to the first coupling mechanism via the first clutch 31. Specifically, the second end of the first transmission shaft 12 is connected to the first output shaft of the dual-output shaft motor via the first clutch 31.

[0044] The second output shaft is connected to the second coupling mechanism via the second clutch 32. Specifically, the first end of the third transmission shaft 22 is connected to the second clutch via the second commutator 24.

[0045] When the first transmission chain needs to work, the first clutch 31 is engaged, the second clutch 32 is disconnected, and the dual output shaft motor 3 is connected to the first transmission chain. Conversely, when the second transmission chain needs to work, the second clutch 32 is engaged, the first clutch 31 is disconnected, and the dual output shaft motor 3 is connected to the second transmission chain. The working order of the two transmission chains can be formulated according to the actual use status or they can work together without affecting each other.

[0046] Preferably, the fourth transmission shaft 23 extends from the third commutator 25 toward one side of the first elevator 11 , so that the second elevator 21 is approximately located in the middle of the first transmission shaft 12 in height.

[0047] In order to further enhance the stability of the horizontal movement of the platform, a third elevator 27 arranged horizontally is further connected to the side of the third commutator 25 away from the second commutator 24 .

[0048] The two second elevators 21 and the two third elevators 27 are symmetrical to each other, forming a 2*2 array distribution.

[0049] It is worth mentioning that the first commutator, the second commutator and the third commutator are preferably 1-LR type commutators. Universal joint couplings are respectively provided at both ends of the first transmission shaft, the second transmission shaft, the third transmission shaft and the fourth transmission shaft. Figure 1 The small circle in the figure shows the universal joint coupling.

[0050] In order to prevent the system from not being able to work properly when the motor fails, in this embodiment, a U-LR type manual commutator is provided on the first transmission shaft 12 and / or the fourth transmission shaft 23. Figures 1 to 3 As shown, the first transmission shaft 12 is provided with a first manual commutator 15, and the fourth transmission shaft 23 is provided with a second manual commutator 26. It is worth mentioning that there are two fourth transmission shafts 23, and the second manual commutator 26 can be provided on only one of them.

[0051] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
