[0033] The following will clearly and completely describe the technical solution of the present invention through specific implementation methods. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] See attached Figures 1 to 11As shown, the present application discloses an integrated lower crossbeam suitable for a high-speed, light-load stacker, comprising an integrated welded lower crossbeam body 1. The structure of the lower crossbeam body 1 has the advantages of strong integrity, high rigidity, good integrity, and light weight. Unlike other mechanical connections, it will not deform excessively due to gap changes under the influence of external forces. Therefore, the strength and rigidity of the welded joint can generally reach or be similar to those of the parent material, and can accept various loads along with the base metal, thereby saving welding and processing costs. The lower crossbeam body 1 is mounted on a ground rail 2, and the lower crossbeam body 1 performs reciprocating linear motion on the ground rail 2, while the rubber-coated walking wheel assembly 3, the walking guide wheel assembly 4, the walking motor 5, the lifting motor 6, and the buffer collision plate 7 are all integrated and mounted on the lower crossbeam body 1. The present application does not have a separate walking wheel box, lifting motor bracket assembly, etc. The overall structural assembly connection is firm, the cost is low, the connection part is beautiful, and it has the advantages of convenient transportation and lifting.

[0035] The walking rubber-coated wheel assembly 3 is installed in pairs at both ends of the lower crossbeam body 1. The walking rubber-coated wheel assembly 3 includes a walking rubber-coated wheel 31, a walking rubber-coated wheel bracket 32, a first eccentric shaft 33 and a first expansion sleeve 34. The walking rubber-coated wheel bracket 32 ​​is installed at the bottom of the lower crossbeam body 1 near the end position. The walking rubber-coated wheel bracket 32 ​​is composed of two triangular plates arranged in pairs. The two triangular plates are placed in the vertical direction. The three corner positions of the two triangular plates are each provided with a first through hole. The triangular plates have the characteristics of stability, firmness, firmness, and pressure resistance. The through holes at the top of the two triangular plates are connected by a sleeve. The first eccentric shaft 33 passes through the sleeve. The two ends of the first eccentric shaft 33 extend out of the outside of the lower crossbeam body 1. The corresponding position of the lower crossbeam body 1 is also provided with a second through hole allowing the two ends of the first eccentric shaft 33 to pass through. The first expansion sleeve 34 is sleeved on the two ends of the first eccentric shaft 33 from the outside of the lower crossbeam body 1. At this time, the walking rubber-coated wheel assembly 3 and the lower crossbeam body 1 are connected together through the first eccentric wheel 33 and the first expansion sleeve 34. The first expansion sleeve 34 of the present application is cleverly designed, providing sufficient torque while being easy to install, disassemble, and adjust. Since the shaft connecting the rubber-coated walking wheel assembly 3 and the integrated welded lower crossbeam body 1 is an eccentric shaft, the level of the stacker can be adjusted by the first eccentric shaft 33. This design structure is novel and easy to adjust. The rubber-coated walking wheels 31 are installed in pairs at the two through holes at the bottom of the triangular plate. The two rubber-coated walking wheels 31 roll on the ground rail 2. The rubber-coated walking wheel assembly 3 of the present application adopts a parallel structure of two rubber-coated walking wheels 31. Under the condition of equal wheel pressure, two wheels can be selected with smaller specifications and models than one wheel. This saves costs and greatly improves the stability of the stacker during high-speed movement. Four rubber-coated walking wheels 31 are used on the lower crossbeam body 1. When running at high speed, the rubber-coated walking wheels 31 can also fully fit with the ground rail 2 to improve the stability of the movement.

[0036] The walking guide wheel assembly 4 is also located at both ends of the lower crossbeam body 1. The walking guide wheel assembly 4 is closer to the end of the lower crossbeam body 1 than the walking rubber-coated wheel assembly 3. The walking guide wheel assembly 4 includes a second expansion sleeve 41, a second eccentric shaft 42, a side guide wheel 43 and a walking guide wheel frame 44. The walking guide wheel frame 44 is mounted on both sides of the ground rail 2 along the width direction. A third through hole is opened on the walking guide wheel frame 44 located on the outside of the ground rail 2. The second eccentric shaft 42 is arranged at the third through hole. The second expansion sleeve 41 is sleeved on both ends of the second eccentric shaft 42. The second expansion sleeve 41 of the present application is cleverly designed to provide sufficient torque while being easy to install, disassemble and adjust. Two first connecting plates 45 are mounted on the second eccentric shaft 42. Side guide wheels 43 are mounted in pairs between the two first connecting plates 45. The two lateral guide wheels 43 are rotatably connected to the two first connecting plates 45. The two lateral guide wheels 43 are located on either side of the second eccentric shaft 42. The two guide wheels 43 roll on the outer side of the ground rail 2. The height of the two guide wheels 43 can be adjusted by the second eccentric shaft 42 to ensure sufficient contact between the two guide wheels 43 and the surface of the ground rail 2. An annular elastic band 46 is mounted on each guide wheel 43. This annular elastic band 46 synchronizes the two guide wheels 43, enhancing motion stability and preventing slippage during operation. A spring 47 is connected to the first connecting plate 45 and the travel guide wheel frame 44. One end of the spring 47 is mounted on the first connecting plate 45, and the other end is mounted on the travel guide wheel frame 44. The two guide wheels 43 can swing about the second eccentric shaft 42. The spring 47 provides sufficient tension to keep the two guide wheels 43 in contact and rolling against the outer upper surface of the ground rail 2.

[0037] A roller group 8 is installed on the walking guide wheel frame 44. The roller assembly 8 includes a pin 48, a roller 81, a second connecting plate 82, a connecting shaft 83, a connecting block 84 and a disc spring 85. The pin 48 is installed on the walking guide wheel frame 44. The second connecting plate 82 has two groups. A fourth through hole and a fifth through hole are opened at both ends of each second connecting plate 82. The size of the fourth through hole is adapted to the size of the pin 48. The second connecting plate 82 is sleeved on the pin 48 through the fourth through hole. The two second connecting plates 82 are both sleeved on the pin 48. The two second connecting plates 82 can rotate on the pin 48. The fifth through hole is adapted to the size of the connecting shaft 83. The second connecting plate 82 is sleeved on the connecting shaft 83 through the fifth through hole. The connecting shaft 83 is The pins 48 are arranged in the same direction, and the rollers 81 are movably connected to the connecting shaft 83. The rollers 81 can swing around the pins 48, wherein the rollers 81 also adopt rubber-coated wheels. The wheels used in this application all adopt rubber-coated wheels. Since the rubber-coated wheels are made of rubber, they have high friction and good grip, so they can prevent the transport equipment from slipping on the slope, which is beneficial to improving the transport efficiency. The rubber structure of the rubber-coated wheels has a good buffering effect, which can disperse the vibration force, thereby reducing the shaking and damage of personnel and equipment. Compared with metal rims, the friction sound of the rubber-coated wheels is smaller, which can reduce the noise emitted by the equipment during transportation. The rubber-coated wheels have good wear resistance, which can reduce the wear of the wheels during long-term use, thereby extending the service life. A connecting block 84 is also installed on the connecting shaft 83, and a disc spring 85 is connected to the connecting block 84. The other end of the disc spring 85 is connected to the walking guide wheel frame 44. The addition of the disc spring 85 provides sufficient tension to ensure that the roller 81 always rolls on the side surface of the ground rail 2. The gap can be adjusted, which greatly reduces the requirement for the straightness of the ground rail 2, facilitates installation and debugging, and saves costs.

[0038] The walking guide wheel frame 44 is equipped with a track brush 49 and a fiber thermoplastic track brush 9. The double brushes are used for high cleaning, which effectively cleans the debris inside the track 2, prevents damage to the walking rubber-coated wheel 31 and reduces the wear of the rubber-coated wheel, thereby extending the service life of the rubber-coated wheel. At the same time, it also avoids the phenomenon of the walking rubber-coated wheel 31 slipping due to foreign matter in the track 2.

[0039] The travel guide wheel frame 44 and the lower cross beam body 1 are connected by a plurality of bolts 10 . A spacer 11 is sleeved on each bolt 10 . The spacer 11 can improve the bending and torsional resistance of the bolt 10 and improve the fatigue performance of the bolt 10 .

[0040] Better, see attached Figure 1 and attached Figure 2As shown. The buffer collision plate 7 of this embodiment is installed on the lower beam body 1. When the stacker needs to work, the travel motor 5 drives the travel rubber-coated wheel assembly 3 and the travel guide wheel assembly 4 on the integrated welded lower beam body 1 to perform reciprocating linear motion along the ground rail 2. When the stacker needs to stop, the buffer collision plate 7 on the integrated welded lower beam body 1 contacts the buffer 12, and the stacker stops smoothly. When the stacker needs to adjust the height, it can be achieved by adjusting the first eccentric shaft 33. High-speed and light-load stackers are generally used in industries with valuables, and valuables generally cannot be bumped. The traditional stacker's lower beam structure is bulky, and most of them use steel wheels. When the stacker is designed in this way, due to the large vibration amplitude and high vibration frequency when running at high speed, it is inevitable that the items will be bumped and damaged. The present application makes up for this defect and can greatly reduce the probability of damage to items. This application has a wide range of applications. It can be used for light-load stackers, shuttle cars, hanging chains and other light equipment in three-dimensional warehouses, as well as the integrated lower beam of high-speed light-load stackers in special industries such as medicine, new energy, cold chain, optoelectronics, and optoelectronic automobile manufacturing.

[0041] Better, see attached Figure 1 As shown, the independently designed torque arms and fixed flange blocks of the travel motor 5 and the lifting motor 6 in this embodiment are easy to install, light in weight, and occupy little space.

[0042] The above description of the disclosed embodiments will enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
