Description

Technical Field

[0001] The utility model relates to logistics equipment, in particular to a fast switching lifting mechanism for a double-column stacker. Background Art

[0002] In recent years, with the continuous expansion of the logistics industry, logistics management methods and technologies have been continuously improved and enhanced. Shortening logistics time, saving logistics costs, improving logistics efficiency, and rationalizing logistics organization are common characteristics of logistics development in economically developed countries. At present, they have modern logistics industry infrastructure. The automated warehouse system is an important part of the modern logistics system and is widely used in all walks of life. Stackers are extremely important equipment in automated warehouses and play a key role in cargo transportation and storage. Today, the rhythm of the warehousing system is very high. Any problem in any link will have a great impact on the production line. As the core equipment of the warehousing system, the operation of the stacker has a great impact on the entire system.

[0003] However, the lifting mechanism of existing stackers generally does not have a quick switching structure, that is, a one-in-one-standby structure for the driving source. Very few stackers use a chain one-in-one-standby lifting mechanism, and the overall height of the structure is limited due to the chain. At the same time, a chain one-in-one-standby lifting mechanism is used, and its structure is that the chain directly drives the cargo platform, resulting in a very large motor power, which increases the cost of use. Under high production rhythm, equipment failure leads to long and uncontrollable downtime.

[0004] Therefore, how to solve the deficiencies in the above-mentioned prior art has become a topic to be studied and solved in this application. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a fast-switching lifting mechanism for a double-column stacker, so as to reduce downtime caused by equipment failure and ensure high-beat operation of the production line.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A quick-switching lifting mechanism for a double-column stacker, mounted on a stacker frame, comprises:

[0008] A driving assembly, comprising a driving base, a first driving motor, a second driving motor, a first coupling, a second coupling and a driving reel, wherein the driving base is mounted on the stacker frame, the first driving motor and the second driving motor are respectively mounted on a side of the driving base away from the stacker frame, the driving reel is mounted on a side of the driving base away from the stacker frame, the first coupling connects an output end of the first driving motor and the driving reel, and the second coupling connects an output end of the second driving motor and the driving reel;

[0009] A quick-cut assembly is mounted on a side of the driving base away from the stacker frame, each of the quick-cut assemblies comprises a first lever and a second lever, the first lever is used in conjunction with the first coupling, and the second lever is used in conjunction with the second coupling;

[0010] When the first lever is used in combination with the first coupling, the first drive motor is engaged with the drive reel, and when the second lever is used in combination with the second coupling, the second drive motor is engaged with the drive reel; when the first lever is away from the first coupling, the first drive motor is separated from the drive reel, and when the second lever is away from the second coupling, the second drive motor is separated from the drive reel.

[0011] Furthermore, the quick-cut assembly includes a first quick-cut base, a second quick-cut base, a first rotating shaft and a second rotating shaft, the first quick-cut base and the second quick-cut base are respectively installed on the side of the driving base away from the stacker frame, the first lever is installed on the first quick-cut base, and the second lever is installed on the second quick-cut base; the first rotating shaft is installed on the first quick-cut base, the first rotating shaft is rotatably connected to the first lever, the second rotating shaft is installed on the second quick-cut base, and the second rotating shaft is rotatably connected to the second lever.

[0012] Furthermore, a first locking handle is installed on the first lever, and a second locking handle is installed on the second lever.

[0013] Furthermore, limit bearings are installed on both sides of the driving reel.

[0014] Furthermore, two groups of lifting steel ropes are arranged on the driving drum, and both groups of lifting steel ropes are wound upward to the pulley on the stacker, and both groups of lifting steel ropes are wound from the pulley to the cargo platform on the stacker.

[0015] Furthermore, the first lever and the second lever are both manual levers.

[0016] Furthermore, both the first drive motor and the second drive motor are reduction motors.

[0017] Furthermore, the first coupling and the second coupling are both clutch-type drum gear couplings.

[0018] Compared with the prior art, the advantages of the present invention are: by setting a first drive motor and a second drive motor, the drive source of the present application is one active and one standby. When one of the drive sources fails, it can be quickly switched to the standby motor drive to ensure stable operation of the equipment. The use of quick-cut components can ensure that the two drive sources are driven separately to improve production efficiency. The shutdown switching time of the present application is short, which can meet high-beat usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solution of the utility model will be clearly and completely described below through specific implementation methods. 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.

[0031] See attached Figures 1 to 8 As shown, a quick-switching lifting mechanism for a double-column stacker of the present application is installed on a stacker frame 3, and includes a drive assembly 1 and a quick-cut assembly 2. The drive assembly 1 includes a drive base 11, a first drive motor 12, a second drive motor 13, a first coupling 14, a second coupling 15 and a drive reel 16. The drive base 11 is installed on the stacker frame 3, the first drive motor 12 and the second drive motor 13 are respectively installed on the side of the drive base 11 away from the stacker frame 3, the drive reel 16 is installed on the side of the drive base 11 away from the stacker frame 3, the first coupling 14 connects the output end of the first drive motor 12 and the drive reel 16, and the second coupling 15 connects the output end of the second drive motor 13 and the drive reel 16. The first drive motor 12 provides torque to the drive drum 16 through the first coupling 14, and the second drive motor 13 provides torque to the drive drum 16 through the second coupling 15. The first drive motor 12 is the main drive source, and the second drive motor 13 is the backup drive source. When the main drive source fails, it can quickly switch to the backup motor drive to ensure stable operation of the equipment.

[0032] The quick-cut assembly 2 is installed on the side of the driving base 11 away from the stacker frame 3. The quick-cut assembly 2 includes a first lever 21, a second lever 22, a first quick-cut base 23, a second quick-cut base 24, a first rotating shaft 25 and a second rotating shaft 26. The first lever 21 is used in conjunction with the first coupling 14, and the second lever 22 is used in conjunction with the second coupling 15. The first quick-cut base 23 and the second quick-cut base 24 are respectively installed on the side of the driving base 11 away from the stacker frame 3. The first lever 21 is installed on the first quick-cut base 23, and the second lever 22 is installed on the second quick-cut base 24. The first rotating shaft 25 is installed on the first quick-cut base 23. The first rotating shaft 25 is rotatably connected to the first lever 21, the second rotating shaft 26 is installed on the second quick-cut base 24, and the second rotating shaft 26 is rotatably connected to the second lever 22. Before the drive assembly 1 operates normally, the backup drive source, i.e., the second drive motor 13, does not operate. The first lever 21 is used to shift the first coupling 14 to separate the drive reel 16 from the first drive motor 12. When the drive assembly 1 is in normal operation, its torque cannot be transmitted to the backup drive source. When it is necessary to switch to the backup drive motor, i.e., the second drive motor 13, the second coupling 15 is first shifted by the second lever 22 to engage the second drive motor 13 with the drive reel 16, and then the first lever 21 is used to separate the first drive motor 12 from the drive reel 16. Through the above steps, the main drive source is switched to the backup drive source. The time consumed in this process can be controlled within 15 minutes. The shutdown switching time is short, which can meet the high-beat usage scenarios.

[0033] The first lever 21 and the second lever 22 can swing left and right. The first lever 21 is equipped with a first locking handle 27, and the second lever 22 is equipped with a second locking handle 28. Taking the first lever 21 as an example, when the first lever 21 swings to the first coupling 14, the first drive motor 12 and the drive reel 16 are engaged. At this time, the first lever 21 is locked by the first locking handle 27 to ensure that the drive torque of the first drive motor 12 is transmitted to the drive reel 16. When the second lever 22 swings to the left or right position, that is, the second lever 22 is away from the second coupling 15, the second drive motor 13 and the drive reel 16 are separated, and the second lever 22 is locked by locking the second handle 28 to ensure that the standby motor is not subjected to force and follows the rotation.

[0034] Therefore, when the first lever 21 is used in combination with the first coupling 14, the first drive motor 12 is meshed with the drive reel 16, and when the second lever 22 is used in combination with the second coupling 15, the second drive motor 13 is meshed with the drive reel 16. When the first lever 21 is away from the first coupling 14, the first drive motor 12 is separated from the drive reel 16, and when the second lever 22 is away from the second coupling 15, the second drive motor 13 is separated from the drive reel 16. The present application adopts a quick-cut assembly 2, and when one drive source fails, the lever is used to quickly switch to another drive source, saving time and improving efficiency.

[0035] For better, see the attached Figure 3 and attached Figure 4 As shown, in this embodiment, limit bearings 4 are installed on both sides of the driving reel 16, and the limit bearings 4 support and fix the driving reel.

[0036] For better, see the attached Figure 1 and attached Figure 3 As shown, in this embodiment, two groups of lifting steel wire ropes 5 are arranged on the driving drum 16, and the two groups of lifting steel wire ropes 5 are wound upward to the pulley on the stacker, and the lifting steel wire ropes 5 are wound from the pulley to the cargo platform on the stacker. Since the two groups of lifting steel wire ropes 5 are wound from the same driving drum 16 to the cargo platform, when the driving drum 16 rotates, the lengths of the two groups of lifting steel wire ropes 5 wound in or out of the driving drum 16 are equal, so the two groups of lifting steel wire ropes 5 have a straight stroke to lift the two ends of the cargo platform, and the cargo platform rises or falls horizontally and steadily. This application adopts a single driving drum drive, and the two groups of lifting steel wire ropes 5 have synchronous strokes, and the cargo platform rises and falls steadily, and will not tilt left and right to cause system alarms or cargo tipping.

[0037] For better, see the attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 6 , Attachment Figure 7 and attached Figure 8 As shown, in this embodiment, the first lever 21 and the second lever 22 are both manual levers. As an practicable manner, the first lever 21 and the second lever 22 can be driven electrically or hydraulically.

[0038] For better, see the attached Figures 1 to 5 As shown, in this embodiment, the first drive motor 12 and the second drive motor 13 are both reduction motors.

[0039] For better, see the attached Figures 2 to 7 As shown, in this embodiment, the first coupling 13 and the second coupling 14 are both clutch-type drum gear couplings.

[0040] The above description of the disclosed embodiments enables professionals in the field to implement or use the utility model. Various modifications to these embodiments will be apparent to professionals in the field, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
