Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 1-3, the present embodiment provides a link jacking device, which may include a rotary motion output mechanism 11, two sets of symmetrically arranged power conversion mechanisms 12, and two sets of power transmission mechanisms symmetrically mounted on the two sets of power conversion mechanisms 12, respectively. Wherein:
the rotational motion output mechanism 11 is for outputting rotational motion.
The power conversion mechanism 12 is configured to convert the rotational motion output from the rotational motion output mechanism 11 into two rotational powers having opposite rotational directions and output the rotational motion. In an example, the power conversion mechanism 12 may include a conversion input shaft 121 and two conversion output shafts 122, the conversion input shaft 121 being coaxially fixed with the output shaft of the rotary motion output mechanism 11 to transmit the rotary motion output by the rotary motion output mechanism 11 into the power conversion mechanism 12.
The power transmission mechanism is used for driving the guide connection plate 22 of the four-way shuttle to do linear motion in the vertical direction under the driving of the two rotary power with opposite rotary directions output by the power conversion mechanism 12, wherein each group of power transmission mechanism can comprise two groups of power transmission units 13, each power transmission unit 13 can comprise a first connecting rod 131 and a second connecting rod 132, one end of the first connecting rod 131 is fixed on the conversion output shaft 122, the other end of the first connecting rod is rotationally connected with one end of the second connecting rod 132, and the other end of the second connecting rod 132 is used for being fixed with the guide connection plate 22 of the four-way shuttle. The guiding connection plate 22 is fixed with a main road wheel 24 of the four-way shuttle and a tray limiting hole 23 for embedding the tray component 5 of the four-way shuttle.
Therefore, when the rotary motion output mechanism 11 works, that is, when the rotary motion is output to drive the first connecting rod 131 and the second connecting rod 132 to rotate, the guide connecting plate 22 can be driven to do linear motion in the vertical direction, and when the guide connecting plate 22 is driven to move to different positions, the running direction of the four-way shuttle is changed, and goods taking is achieved. For example, when the rotary motion output mechanism 11 drives the guide connection plate 22 to rise to the first position in the vertical direction, the height of the main road wheel 24 may be higher than the height of the auxiliary road wheel 34 of the four-way shuttle, so that the auxiliary road wheel 34 is located on the auxiliary road, and the main road wheel 24 is suspended on the main road. Thus, the traveling direction of the four-way shuttle can be changed from the main road to the auxiliary road. For another example, after the traveling direction of the four-way shuttle is changed, the rotary motion output mechanism 11 continues to work, and drives the guide connection plate 22 to continuously ascend in the vertical direction until the guide connection plate ascends to the second position, so that the tray assembly 5 is embedded into the tray limiting hole 23, and the top end of the four-way shuttle and the bottom of the tray assembly 5 form press contact, so that the four-way shuttle can finish load bearing on the tray assembly 5, and the goods taking is realized.
By driving the guide connection plate 22 to move to different positions, the change of the running direction of the four-way shuttle and the goods taking are realized. Therefore, the same rotary motion output mechanism 11 provides power, so that the coupling of the jacking and reversing functions can be realized, and related motion parts, such as the power transmission unit 13 formed by the first connecting rod 131 and the second connecting rod 132, can be maintenance-free, and have the advantages of simple structure, low production cost, long service life and the like.
In an alternative embodiment of the invention, the number of the rotary motion output mechanisms 11 is two, and the rotary motion output mechanisms 11 may include a rotary motion output 111 and a coupling 112, wherein:
the rotary motion output 111 is fixed to the frame 4 of the four-way shuttle. The output shaft of the rotary motion output 111 serves as the output shaft of the rotary motion output mechanism 11. In one example, the rotational motion output 111 may be a gear motor.
The coupling 112 is coaxially connected to the output shaft of the rotary motion output 111 and the conversion input shaft 121. Thus, each set of rotary motion output mechanisms 11 provides a power source to one set of power conversion mechanisms 12 and two sets of power transmission mechanisms.
In another alternative embodiment of the invention, referring to fig. 1, the rotary motion output mechanism 11 may further include a rotary motion output 111, a lifting transmission shaft 113, two couplings 112, and a lifting sprocket transmission unit 114. Wherein:
the rotary motion output 111 is fixed to the frame 4 of the four-way shuttle.
The jacking transmission shaft 113 is rotatably connected to the frame 4 of the four-way shuttle.
The two couplings 112 are respectively disposed at two ends of the jacking transmission shaft 113, so as to coaxially connect the jacking transmission shaft 113 and the conversion input shaft 121, wherein the jacking transmission shaft 113 is used as an output shaft of the rotary motion output mechanism 11.
The jacking sprocket drive unit 114 is disposed between the output shaft of the rotary motion outputter 111 and the jacking transmission shaft 113, so that the rotary motion outputter 111 drives the jacking transmission shaft 113 to rotate. For example, the output shaft of the rotary motion follower 111 and the jack-up transmission shaft 113 are installed in parallel. The jacking sprocket drive unit 114 may include two jacking drive sprockets and a jacking drive chain engaged with the jacking drive sprockets. For example, one jacking transmission sprocket may be coaxially fixed to the output shaft of the rotary motion output device 111, and the other jacking transmission sprocket may be coaxially fixed to the jacking transmission shaft 113, whereby the rotary motion conversion of the two sets of the power conversion mechanisms 12 can be achieved by one rotary motion output device 111. The lifting reversing device can be more compact and simpler in structure.
On the one hand, the symmetrical arrangement of the power conversion mechanism 12 and the power transmission mechanism can reduce the torque of the upper load of the four-way shuttle to the rotary motion output device 111, so that the load capacity of the whole vehicle can be improved, and the device can be suitable for a heavy-load scene. On the other hand, 8 groups of symmetrically distributed power transmission units 13 are adopted, the unbalanced load resistance is strong, and the situation that goods are unevenly stacked on the tray assembly 5 of the four-way shuttle can be dealt with. On the other hand, the power transmission unit 13 has small abrasion during operation, long service life and low maintenance cost.
In an alternative embodiment of the invention, the rotary motion output mechanism 11 may further comprise two jacking bearings 115 fixed to the frame 4. The jacking transmission shafts 113 are arranged on the two jacking bearing supports 115 in a penetrating mode, and are connected with the jacking bearing supports 115 in a rotating mode. The installation interval of the two jacking bearings 115 may be determined according to the length of the jacking transmission shaft 113, which is not limited herein.
In an alternative embodiment of the invention, referring to fig. 4, the power conversion mechanism 12 may further include a housing 123, a first bevel gear pair 124, a conversion drive shaft 125, a second bevel gear pair 126, and a third bevel gear pair 127. For example, the conversion input shaft 121 and the conversion output shaft 122 are rotatably connected to both sides of the case 123, respectively, and the conversion input shaft 121 and the conversion output shaft 122 are disposed in parallel. The rotation conversion angles of the first bevel gear pair 124, the second bevel gear pair 126, and the third bevel gear pair 127 are each 90 °. The conversion drive shaft 125 is disposed perpendicular to the conversion input shaft 121 and is rotatably coupled to the housing 123 via a conversion bearing mount. The second bevel gear pair 126 and the third bevel gear pair 127 have the same structure and are symmetrically installed at both ends of the shift drive shaft 125. The conversion input shaft 121 is connected to a first bevel gear, and the two conversion output shafts 122 are connected to a second bevel gear pair 126 and a third bevel gear pair 127, respectively. Thus, the rotational motion input from the conversion input shaft 121 can be converted into two rotational powers in opposite rotational directions by the first bevel gear pair 124, the second bevel gear pair 126, and the third bevel gear pair 127, and output by the two conversion output shafts 122.
Referring to fig. 4-8, the present application also provides a four-way shuttle that may include a frame 4, a main road driving wheel assembly 2, an auxiliary road driving wheel assembly 3, a tray assembly 5, and a link lifting device 1 as described in any of the above. The frame 4 is used for supporting all parts and installation of the four-way shuttle. As shown in fig. 5, a reinforcing plate 401 for increasing structural strength of the four-way shuttle may be further disposed in the frame 4. The main road driving wheel device 2 is used for driving the four-way shuttle to run on the main road. The auxiliary road driving wheel device 3 is used for driving the four-way shuttle to run on an auxiliary road. The tray assembly 5 is used for carrying goods.
Referring to fig. 5, 6 and 7, the main road driving wheel apparatus 2 may include a plurality of guide bars 21, two guide connection plates 22 and a plurality of main road wheels 24, wherein:
a plurality of guide rods 21 are vertically fixed to the frame 4.
The two guide connection plates 22 are symmetrically arranged on two sides of the frame 4, wherein the two sides provided with the guide connection plates 22 are opposite sides and are respectively connected to the guide rod 21 in a sliding manner. In an example, the guide rods 21 may be sliding rails, corresponding to each other, the side portions of the guide plates may be provided with sliding blocks, and the sliding blocks and the sliding rails are matched to form a sliding connection, where each guide connection board 22 may be slidably connected with a plurality of guide rods 21, preferably, in order to ensure structural stability of the four-way shuttle, the number of the guide rods 21 may be 4, and two guide rods 21 are symmetrically disposed with respect to the guide connection board 22.
And, a tray limiting hole 23 is formed at the top end of each guide connection plate 22. For example, the tray assembly 5 may include a horizontally disposed pallet and a tray bar 501 vertically disposed at the bottom of the pallet. Wherein, the tray rod 501 can be embedded into the tray limiting hole 23 to form sliding connection between the supporting plate and the guide connecting plate 22. When applied to a three-dimensional warehouse, the pallet assembly 5 can be removed from the four-way shuttle in advance for carrying goods. When goods are required to be taken, the guide connecting plate 22 can be lifted through the connecting rod lifting device 1, so that the tray rod 501 can enter the tray limiting hole 23 and is in press contact with the guide connecting plate 22 until the supporting plate is in press contact with the guide connecting plate 22, and therefore goods are taken.
The main road wheels 24 are respectively installed on the two guide connection plates 22 and are rotatably connected with the guide connection plates 22. The number of the main road wheels 24 is not limited herein, and for example, the number of the main road wheels 24 may be 4, 5, 6, or the like.
