Description

Technical Field

[0001] The utility model relates to the technical field of stacker manufacturing technology, in particular to a lower cross beam of a double-driven stacker with one for use and one for standby. Background Art

[0002] With the acceleration of economic globalization, the huge potential contained in the automated warehouse has attracted more and more attention. As an important part of the logistics center, the automated warehouse (Automatic Storage & Retrieval System) directly affects the strategy and plan formulated by the enterprise, and directs and adjusts the actions of the enterprise. Due to the high access efficiency of the automated warehouse, it can effectively connect the production links outside the warehouse, and can form an automated logistics system in the storage, thereby forming a planned and organized production chain, which has greatly improved the production capacity. The automated warehouse has become one of the symbols of the informationization of enterprise production and management. The stacker is one of the core equipment of the entire automated warehouse. The lower beam is also the core component of the stacker. Now many companies attach great importance to the beat and flow, but the failure of the drive motor is inevitable. It often takes a lot of time to investigate and repair, resulting in the stop of the entire production line, affecting the flow of in and out of the warehouse, and causing economic losses.

[0003] In addition, the existing lower crossbeams are basically single-driven. Once a problem occurs in the motor during operation, it is necessary to manually troubleshoot and solve the problem, causing the entire production line to stop running, affecting the flow and production scheduling of the entire three-dimensional warehouse, and directly causing large economic losses. Some projects will have a spare motor on site, but it is troublesome to replace the motor and takes a lot of time. The stacker sometimes breaks down in the middle of the lane. Since the lane space is narrow and there is no large maintenance area, it is inconvenient to repair, and the operation is limited and unsafe. At the same time, the existing motor bracket has a complex structure, does not have enough space, is inconvenient to assemble, cannot be adjusted, and is difficult to install the drive motor.

[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

[0032] 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.

[0033] See attached Figures 1 to 9As shown, the present application discloses a dual-drive stacker lower beam with one for use and one for standby, comprising a ground rail 1, a lower beam 2, a driving wheel box assembly 3, a motor bracket assembly 4 and a walking guide wheel assembly 5. The ground rail 1 is arranged on the ground, the lower beam 2 is arranged on the ground rail 1, the lower beam 2 is slidably connected with the ground rail 1, and the lower beam 2 performs reciprocating linear motion on the ground rail 1. The driving wheel box assembly 3 is arranged in pairs at both ends of the lower beam 2, and the driving wheel box assembly 3 includes a driving motor 31, a roller chain coupling 32, a flat key 33 and a driving shaft 34. The output end of the driving motor 31 is connected to the flat key 33, and the flat key 33 and the driving shaft 34 are arranged in the roller chain coupling 32. When the stacker needs to work, the driving motor 31 is powered, and the driving motor 31 drives the roller chain coupling 32 to rotate through the flat key 33, and the roller chain coupling 32 drives the driving shaft 34 to rotate through the flat key 33. The roller chain coupling 32 is movably connected with a chain. When the stacker is working normally, the chain on the roller chain coupling 32 at one end of the lower beam 2 is installed to drive the entire stacker to operate. When one of the drive motors 31 fails, it is only necessary to quickly remove the chain on the roller chain coupling 32 and install it on the spare side to quickly restore the operation of the entire three-dimensional warehouse, which will not affect the flow and production scheduling of the entire three-dimensional warehouse. The present application adopts a dual-drive structure of one for use and one for standby. After one of the drive motors 31 fails, the spare drive motor 31 can quickly take over the work. When the stacker has no work demand, it can troubleshoot and deal with the problem. Reasonable coordination time will not affect the flow, safety and reliability of the entire three-dimensional warehouse. At the same time, the design of two drive motors 31, one for use and one for standby, can significantly improve the reliability and stability of the equipment, is suitable for scenes with high requirements for equipment stability, and can greatly improve production efficiency. The solution of using two drive motors 31, one for use and one for backup, can reduce the wear and heat loss of the drive motor 31, extend the service life of the drive motor 31, and improve the overall reliability of the equipment. The backup drive motor 31 can replace the main drive motor 31 during fatigue, failure and maintenance.

[0034] The motor bracket assembly 4 is arranged in pairs at the two ends of the lower cross beam 2. The motor bracket assembly 4 is used in conjunction with the driving wheel box assembly 3. The motor bracket assembly 4 includes a first bracket 41 and a second bracket 42. The first bracket 41 includes a vertically arranged first flange plate 411 and two horizontally arranged top screw plates 412. The two top screw plates 412 are welded under the processed first flange plate 411. The second bracket 42 includes a first square tube 421, a second square tube 422, a second flange plate 423, a third flange plate 424, a first rib plate 425 and a second rib plate 426. The second flange plate 423 is vertically fixed on the first flange plate 411. One end of the second square tube 422 is connected to the second flange plate 423 and the other end is connected to the first square tube 421. The third flange plate 424 is vertically arranged. The other end of the first square tube 421 is connected to the third flange plate 424. The first rib plate 425 is installed on the upper part of the second square tube 422. The first rib plate 424 is connected to the second flange plate 423. The second rib plate 426 is installed below the second square tube 422. The second square tube 422 is connected to the second flange plate 423. The entire motor bracket assembly 4 is welded and then processed as a whole. It has a simple structure, is easy to assemble, and reasonably uses the process of first processing and then welding and first welding and then processing, thereby improving the accuracy of the entire motor bracket assembly 4 and greatly saving the processing cost. The motor bracket assembly 4 is cleverly designed and easy to install, and sufficient space is reserved to facilitate timely replacement of the chain of the roller chain coupling 32 .

[0035] Because of the processing, the drive motor 31 does not need to be adjusted in the X-axis direction when installed. The roller chain coupling 32 has an axial compensation amount, so the drive motor 31 has an adjustment amount in the Z-axis direction. The first bracket 41 is provided with a top screw plate 412, so the drive motor 31 has an adjustment amount in the Y-axis direction. In summary, the drive motor is easy to install and disassemble during maintenance.

[0036] The roller chain coupling 32 has low requirements for coaxiality, has certain compensation for radial, axial and angular directions, and is easy to install. The roller chain coupling 32 used in this application is low in cost, simple in structure, easy to replace, reliable in operation, and can transmit greater torque. When it is occasionally necessary to transport special heavy-duty goods, the chains of the roller chain coupling 32 at both ends can be installed, and the mode of the heavy-duty stacker can be switched.

[0037] See attached Figure 1 and attached Figure 2 As shown, in this embodiment, the travel guide wheel assembly 5 is arranged below the driving wheel box assembly 3, and the travel guide wheel assembly 5 plays a limiting role and can effectively prevent the lower beam 2 from running off.

[0038] See attached Fig.10As shown, as an implementable method, the purpose of the present application can be achieved by adopting a sprocket solution. A sprocket 7 is installed on the side of the driving motor 31, and a chain 6 is movably connected to the sprocket 7. When the driving motor 31 fails, the chain 6 can be removed from the sprocket 7 for quick replacement.
