Description

TECHNICAL FIELD

[0001] The present application belongs to the field of hoist, in particular to a track docking device, a docking method and a hoist system. BACKGROUND

[0002] With the continuous development of the logistics industry, the hoist lifting and layer changing become an essential tool for the circulation of goods. There are different technical problems in the docking of each layer when the hoist changes layers. For example, when the hoist is matched with a shuttle vehicle to load the cargo platform and dock with the lifting and layer changing track, there will be a gap when the hoist changes layers and docks with the track, which will cause the shuttle vehicle to pass unevenly, or the docking device structure is complex and the cost is high. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a track docking device, a docking method and a hoist system which can make the track docking stable and smooth, and simple and practical to process.

[0004] The present application provides a track docking device, which comprises a first docking assembly and a second docking assembly arranged opposite to each other, the first docking assembly comprises a rotating drive device arranged on a first track and a docking block arranged on the output end of the rotating drive device, and the second docking assembly comprises a matching block rotatably arranged on a second track, the docking block is provided with a straight slot or a clamping block on the side facing the matching block, and the matching block is provided with a clamping block or a straight slot on the side facing the docking block.

[0005] Further, the clamping block is provided with two clamping blocks on the opposite side of the rotating axis of the rotating drive device.

[0006] Further, the side of the docking block is provided with a first blocking block.

[0007] Further, the entrance of the straight slot is provided with a chamfer.

[0008] Further, the first docking assembly further comprises a first bracket, the rotating drive device is arranged on the first bracket, and the rotating drive device is fixed on the first track through the first bracket.

[0009] Further, the second docking assembly further comprises a second bracket, the matching block is rotatably arranged in the second bracket, and the matching block is fixed on the second track through the second bracket.

[0010] Further, the second docking assembly further comprises a torsion spring, one end of the torsion spring is connected with the matching block, and the other end of the torsion spring is connected with the second bracket.

[0011] Further, the side of the matching block is provided with a second blocking block.

[0012] The present invention also provides a track docking method using the above-mentioned track docking device, comprising a docking process and a separation process:

[0013] The docking process includes: the first track moves vertically to the position of the second track, and the first track and the second track are collinear. During the movement of the first track, the locking block is inserted into the straight groove. The rotation drive device drives the docking block to rotate, which in turn drives the locking block and the straight groove to rotate, so that the straight groove is perpendicular to the movement direction of the first track, thus completing the docking of the first track and the second track.

[0014] The separation process includes: the rotary drive device drives the docking block to rotate, which in turn drives the locking block and the straight groove to rotate, so that the straight groove is parallel to the moving direction of the first track. The first track can move freely along the moving direction, thus completing the separation of the first track and the second track.

[0015] The present invention also provides a hoisting system, including a loading platform and at least two entry and exit layers, wherein a first track is provided on the loading platform and a second track is provided on the entry and exit layers, and the system also includes the aforementioned track docking device.

[0016] The beneficial effects of this invention are as follows: Before docking, the straight groove is collinear with the docking direction of the two tracks, allowing them to approach each other. The docking block can then be directly inserted into the straight groove. Subsequently, the rotary drive device drives the docking block to rotate, causing the straight groove and the locking block to rotate together, preventing the first and second tracks from separating in the docking direction. This completes the docking of the first and second tracks. The entire docking process is convenient and quick. After docking, the rotary drive device does not operate, or will not separate without external force. The docking provides good stability and ensures a smooth and stable connection between the first and second tracks, improving the stability of the shuttle's movement. Furthermore, during separation, the rotary drive device must be reset. The first and second tracks can be separated, and the reset does not affect their relative displacement along the docking direction. The entire docking and separation process is convenient, quick, and easy to control. The track docking is stable and smooth, and the processing is simple and practical. Attached Figure Description

[0031] As attached Figures 1-8 As shown, the present invention provides a track docking device for separating and docking two tracks perpendicular to their length direction, for example... Figure 1 The separation and docking of the first track 5 and the second track 6 in the Z and X directions includes a first docking component 1 and a second docking component 2 arranged opposite to each other. The first docking component 1 includes a rotary drive device 11 arranged on the first track 5 and a docking block 12 arranged on the output end of the rotary drive device 11. The second docking component 2 includes a mating block 21 rotatably arranged on the second track 6. The docking block 12 is provided with a straight groove 3 on the side facing the mating block 21. The mating block 21 is provided with a locking block 4 on the side facing the docking block 12. Alternatively, the docking block 12 is provided with a locking block 4 on the side facing the mating block 21, and the mating block 21 is provided with a straight groove 3 on the side facing the docking block 12.

[0032] refer to Figure 4 Before docking, the straight groove 3 is collinear with the docking direction of the two tracks, as shown in the reference. Figure 3 At this point, the two tracks are close together, and the docking block 12 can be directly inserted into the linear groove 3. (Refer to...) Figure 2, and then the rotating driving device 11 drives the butt joint block 12 to rotate, the linear slot 3 rotates together with the clamping block 4, so that the first track 5 and the second track 6 cannot be separated in the butt joint direction, and the butt joint of the first track 5 and the second track 6 is completed. The whole butt joint process is convenient and fast, the rotating driving device 11 does not act after butt joint, or cannot be separated under the action of no external force, the stability after butt joint is good, and the butt joint can guarantee that the first track 5 and the second track 6 are smoothly and stably connected, and the walking stability of the shuttle vehicle is improved. In addition, the rotating driving device 11 needs to be reset when being separated, the first track 5 and the second track 6 can be separated, and the reset does not affect the relative displacement of the first track 5 and the second track 6 in the butt joint direction, so that the whole butt joint and separation process is convenient and fast, and is convenient to control.

[0033] In one of the embodiments, the clamping block 4 is provided with two opposite sides along the rotation axis of the rotating driving device 11, and in the embodiment, the clamping block 4 preferably adopts a cylindrical body, which can save materials and facilitate the insertion of the clamping block 4 into the linear slot 3. It should be noted that the clamping block 4 can also be other structures, for example, a cuboid, which can move linearly along the linear slot 3.

[0034] In one of the embodiments, the side of the butt joint block 12 is provided with a first blocking block 13. When the first track 5 and the second track 6 are in a separated state, that is, the butt joint block 12 and the matching block 21 are in a state of preparing to butt joint, the first blocking block 13 faces the side of the first track 5, which can block the shuttle vehicle on the first track 5 from sliding out of the first track 5, and block the shuttle vehicle in the loading platform 7. When the first track 5 and the second track 6 are in a butt joint state, that is, after the butt joint block 12 and the matching block 21 are butt jointed, the first blocking block 13 rotates with the butt joint block 12 to cancel the blocking of the first track 5, and at this time, the shuttle vehicle can smoothly shuttle between the first track 5 and the second track 6. The embodiment increases the first blocking block 13 on the butt joint block 12, and can complete the separation of the tracks, the blocking of the tracks, and the butt joint of the tracks, and the release of the blocking of the tracks synchronously without additionally increasing power control settings, which greatly improves the function and practicability of the butt joint device.

[0035] In one of the embodiments, the entrance of the linear slot 3 is provided with a chamfer 31, as shown in Figure 7 and Figure 8 In the embodiment, the linear slot 3 is preferably through at both ends, that is, the clamping block 4 can enter from one end of the linear slot 3 and slide out from the other end, and at this time, the two ends of the linear slot 3 are provided with chamfers 31. Of course, the linear slot 3 can also have one end as an entrance and the other end closed, that is, the clamping block 4 can only enter from the entrance end and slide out from the entrance end, and at this time, the entrance of the linear slot 3 is provided with chamfers 31 on both sides. By providing the chamfer 31, the clamping block 4 can enter the linear slot 3, and the butt joint difficulty is reduced.

[0036] In one embodiment, the first docking assembly 1 further comprises a first support 14, and the rotary driving device 11 is arranged on the first support 14, and the rotary driving device 11 is fixed on the first track 5 through the first support 14. The first support 14 is preferably a frame structure, which facilitates the installation of the rotary driving device 11 and provides physical protection for the rotary driving device 11. The rotary driving device 11 is preferably a combination of a motor and a speed reducer.

[0037] In one embodiment, the first docking assembly 1 further comprises a first rotary angle to position sensor 15 arranged on the first support 14. The first rotary angle to position sensor 15 is used to obtain the state of the docking block 12, i.e., whether it is in a ready-to-dock state or a docked state. Specifically, the first rotary angle to position sensor 15 comprises an inductive sheet 151 arranged on the output shaft of the rotary driving device 11 and a micro switch 152 arranged on the first support 14. When the micro switch 152 is aligned with the inductive sheet 151, the docking block 12 is in the ready-to-dock state or the docked state. In addition, a second rotary angle to position sensor 25 can also be arranged on the second docking assembly 2 to facilitate the control equipment to obtain the state of the second docking assembly 2.

[0038] In one embodiment, the second docking assembly 2 further comprises a second support 22, and the matching block 21 is rotatably arranged in the second support 22. The matching block 21 is fixed on the second track 6 through the second support 22. The first support 14 is preferably a frame structure, which facilitates the rotary fixation of the matching block 21 and simplifies the installation difficulty of the second docking assembly 2 and the second track 6.

[0039] In one embodiment, the second docking assembly 2 further comprises a torsional spring 23, one end of which is connected to the matching block 21 and the other end of which is connected to the second support 22. The torsional spring 23 causes the matching block 21 to be in a ready-to-dock state. Specifically, in the separated state, the torsional spring 23 drives the matching block 21 to be in the docking state. When docking, the docking block 12 drives the matching block 21 to rotate, and at the same time, the matching block 21 compresses the torsional spring 23, which accumulates force and drives the matching block 21 to tightly fit with the docking block 12. When separating, the torsional spring 23 resets and drives the matching block 21 to turn to the ready-to-dock state.

[0040] In one of the embodiments, the second blocking block 24 is arranged at the side of the matching block 21, and when the first track 5 and the second track 6 are in the separated state, i.e. the abutting block 12 and the matching block 21 are in the state ready for abutting, the second blocking block 24 at the side of the second track 6 can block the shuttle vehicle on the second track 6 from sliding out of the second track 6, and the shuttle vehicle is blocked in the in-out layer 8, and when the first track 5 and the second track 6 are in the abutting state, i.e. the abutting block 12 and the matching block 21 are abutted, the second blocking block 24 is reset following the rotation of the matching block 21, and the blocking of the second track 6 is cancelled, and at this time, the shuttle vehicle can smoothly shuttle between the first track 5 and the second track 6. In this embodiment, the second blocking block 24 is added to the matching block 21, and without the need of adding a power control device, the track separation, the track limiting blocking, the track abutting and the track limiting unblocking can be synchronously performed, and the function and the practicability of the abutting device are greatly improved.

[0041] The application further provides a track abutting method using the track abutting device, and the method comprises an abutting process and a separating process.

[0042] The abutting process comprises: vertically moving the first track 5 to the position of the second track 6, and the first track 5 and the second track 6 are collinear, in the moving process of the first track 5, the engaging block 4 is inserted into the straight slot 3, the rotating driving device 11 drives the abutting block 12 to rotate, and drives the engaging block 4 and the straight slot 3 to rotate, so that the straight slot 3 is perpendicular to the moving direction of the first track 5, and the abutting of the first track 5 and the second track 6 is completed.

[0043] The separating process comprises: the rotating driving device 11 drives the abutting block 12 to rotate, and drives the engaging block 4 and the straight slot 3 to rotate, so that the straight slot 3 is parallel to the moving direction of the first track 5, and the first track 5 can freely move along the moving direction, and the separation of the first track 5 and the second track 6 is completed.

[0044] In the application to the elevator system, the first track 5 vertically moves up and down, and the second track 6 is fixedly arranged on the in-out layer 8, at this time, the default state of the straight slot 3 is the vertical state, so that the first track 5 and the second track 6 are in the default separated state, and are switched to the abutting state only when needed.

[0045] The application further provides an elevator system, which comprises a cargo platform 7 and at least two in-out layers 8, the cargo platform 7 is provided with the first track 5, the in-out layer 8 is provided with the second track 6, and further comprises the above track abutting device, i.e. the first abutting assembly 1 with the rotating driving device 11 is arranged on the cargo platform 7, and the second abutting assembly 2 is arranged on the second track 6 of each in-out layer 8. That is, one first abutting assembly 1 corresponds to the use of multiple second abutting assemblies 2, and only one rotating driving device 11 is needed to realize the abutting and separation of one first track 5 and multiple second tracks 6, so that the structure is simplified and the cost is reduced.

[0046] It should be noted that the second track 6 can also be arranged on the loading platform 7, and the first track 5 is arranged on the access layer 8, that is, the first docking assembly 1 with the rotating driving device 11 is arranged on the access layer 8, and the second docking assembly 2 is arranged on the first track 5 of each access layer 8.
