[0032] The utility model embodiment provides a kind of lifting appliance driving mechanism and logistics loading and unloading device model, the lifting appliance driving mechanism can drive lifting appliance horizontal reciprocating movement or vertical lifting, and guarantee the stability when lifting appliance moves.

[0033] The technical scheme provided by the utility model will be described in more detail below. Figures 1-6 The technical scheme provided by the utility model will be described in more detail below.

[0034] Embodiment 1:

[0035] The lifting appliance driving mechanism provided by the utility model, the translation driving mechanism 3 can drive the lifting driving mechanism 2 to reciprocate along the X-axis track 11, so as to drive the lifting appliance 8 to move horizontally; the driving shaft 22 in the lifting driving mechanism 2 drives the driven shaft 23 to rotate synchronously, so as to drive the first winding wheel 24 and the second winding wheel 25 to rotate synchronously; the lifting appliance 8 can be lifted or lowered stably by the lifting appliance driving mechanism.

[0036] The lifting appliance 8 is a device with a clamping jaw and is used for grabbing or releasing a container.

[0037] The lifting traction part 26 can be a steel wire rope, as shown in the drawing, the lifting traction part 26 (a steel wire rope in the drawing) wound on the first winding wheel 24 and the second winding wheel 25 is wound or released synchronously, so as to drive the two sides of the lifting appliance 8 to move synchronously, thereby ensuring the stability of the lifting appliance 8. Figure 3

[0038] Specifically, since the driving shaft 22 and the driven shaft 23 are in transmission connection and rotate synchronously, the first winding wheel 24 and the second winding wheel 25 rotate synchronously, so as to make the lifting traction part 26 wound on the first winding wheel 24 and the second winding wheel 25 to be wound or released synchronously.

[0039] The lifting appliance driving mechanism of the embodiment can drive the lifting appliance 8 to move horizontally and vertically reciprocally and ensure the stability of the lifting appliance 8 when moving.

[0040] As an optional embodiment, as shown in the drawing, the lifting appliance driving mechanism comprises a lifting appliance 8, a lifting appliance driving mechanism and a translation driving mechanism 3. Figure 5 ​As shown, the lifting driving mechanism 2 further comprises a lifting driving device 29, which can be a motor or the like, and is fixed to the lifting frame 21 and drivingly connected with the driving shaft 22 to drive the driving shaft 22 to rotate forward or reversely. The driving shaft 22 of the embodiment is fixed with a driving gear 27, and the driven shaft 23 is fixed with a driven gear 28 which is engaged with the driving gear 27.

[0041] The lifting driving device 29 drives the driving shaft to rotate through a belt drive, a chain drive or the like. Since the driving gear 27 fixed on the driving shaft is engaged with the driven gear 28 fixed on the driven shaft 23, the driven shaft 23 rotates reversely synchronously, i.e. the first winding wheel 24 and the second winding wheel 25 rotate reversely synchronously.

[0042] It should be understood that the first winding wheel 24 and the second winding wheel 25 rotate reversely synchronously, but the winding directions of the lifting traction part 26 on the first winding wheel 24 and the second winding wheel 25 are opposite. Thus, when the first winding wheel 24 and the second winding wheel 25 rotate reversely synchronously, the lifting traction part 26 wound on the first winding wheel 24 and the second winding wheel 25 is wound or released synchronously, so that the lifting appliance 8 always keeps horizontal lifting and prevents the lifting appliance 8 from tilting.

[0043] The first winding wheel 24 and the second winding wheel 25 can be provided with spiral grooves to wind the lifting traction part 26.

[0044] As an optional embodiment, referring to Figure 5 The first winding wheel 24 is provided with two and located at opposite sides of the driving gear 27 respectively, and the traction parts wound on all the first winding wheels 24 are connected with two end corners of the lifting appliance 8 respectively. The second winding wheel 25 is provided with two and located at opposite sides of the driven gear 28 respectively, and the traction parts wound on all the second winding wheels 25 are connected with the other two end corners of the lifting appliance 8 respectively.

[0045] The above structure is that one closed lifting traction part 26 is wound on the two first winding wheels 24, and the other closed lifting traction part 26 is wound on the two second winding wheels 25. Each lifting traction part 26 is wound around the fixed pulley on one side of the lifting appliance 8. In this way, the lifting traction part 26 can be slidably connected with the fixed pulleys of the four end corners of the lifting appliance 8, so that the lifting appliance 8 always keeps a balanced state.

[0046] As an optional embodiment, referring to Figures 1-3As shown in the figure, the translation drive mechanism 3 includes a translation drive wheel set, which includes a coaxially arranged drive wheel 31, a third winding wheel 32, and a fourth winding wheel 33. The drive wheel 31 drives the shaft on which it is located to rotate, thereby driving the third winding wheel 32 and the fourth winding wheel 33 to rotate synchronously. The third winding wheel 32 and the fourth winding wheel 33 are provided with translation traction parts 34, which are fixedly connected to the opposite sides of the lifting frame 21, respectively, for pulling the lifting frame 21 to move horizontally.

[0047] The aforementioned "translation traction unit 34" can be a steel wire rope, see [link / reference]. Figure 2 As shown, the translational traction part 34 (the wire rope in the figure) wound around the third winding wheel 32 and the fourth winding wheel 33 is wound or released synchronously, thereby driving the two sides of the lifting frame 21 to rise and fall synchronously, thus ensuring the stability of the lifting of the lifting device 8.

[0048] As an optional implementation, see Figure 6 As shown, the translation drive mechanism 3 includes a translation drive device 35, which can be a motor. The translation drive device 35 is fixed on the frame 1 and is connected to the drive wheel 31 for driving the drive wheel 31 to rotate in the forward or reverse direction.

[0049] When the translation drive device 35 drives the drive wheel 31 to rotate, since the drive wheel 31, the third winding wheel 32, and the fourth winding wheel 33 are fixed on the same shaft, the third winding wheel 32 and the fourth winding wheel 33 rotate synchronously, the two translation traction parts 34 are wound or released synchronously, and the opposite sides of the lifting frame 21 move horizontally synchronously.

[0050] As an optional implementation, see Figure 3 and Figure 4 As shown, reversing wheels 7 are provided at opposite ends of the X-axis track 11. The reversing wheels 7 are rotatably connected to the frame 1, and the translational traction unit 34 is wrapped around the reversing wheels 7 to be fixedly connected to the lifting frame 21.

[0051] The above structure enables the translational traction unit 34 to pull the lifting frame 21 to move horizontally back and forth along the X-axis track 11.

[0052] As an optional implementation, see Figure 4 As shown, one end of the X-axis track 11 is provided with a first connecting rod 4 and a second connecting rod 5. One end of the first connecting rod 4 is fixed to the frame 1, and the other end is rotatably connected to the upper end of the second connecting rod 5. The other end of the second connecting rod 5 is rotatably connected to one of the reversing wheels 7. The middle part of the second connecting rod 5 is rotatably connected to the middle part of the first connecting rod 4 through a turnbuckle 6.

[0053] By adjusting the turnbuckle 6, the included angle between the first link 4 and the second link 5 can be adjusted, thereby adjusting the position of the reversing wheel 7 and thus adjusting the tightness of the translation traction unit 34.

[0054] Embodiment 2:

[0055] The embodiment provides a logistics handling device model, which comprises a sling 8 and the sling driving mechanism, and a lifting traction part 26 is connected with the sling 8.

[0056] As shown in Figure 3 The lifting traction part 26 can be a steel wire rope, which is connected with a fixed pulley on the sling 8.

[0057] The logistics handling device model can stably simulate horizontal movement and vertical lifting movement of the sling 8, and guarantees the stability of the structure.

[0058] In the description of the specification, the specific features, structures or characteristics can be combined in any one or more embodiments or examples in a suitable manner.
