Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] Please refer to Figures 1-6 ​The utility model provides a kind of anti-swing device for stacking machine, including crossbeam 1, the inside of crossbeam 1 is detachably installed with support 2, the number of support 2 has two groups, the installation position of support 2 is located in the inside of double-column stacking machine crossbeam 1, two groups of support 2 are bolted on crossbeam 1, according to actual situation, crossbeam 1 is holed, to facilitate the installation of the equipment, two groups of support 2 are detachably installed with linear shaft sleeve 3, the inner surface of two groups of linear shaft sleeve 3 is rotatably connected with inner shaft 4, the end of two groups of inner shaft 4 away from linear shaft sleeve 3 is fixedly connected with center shaft 5, the outer surface of center shaft 5 is slidably connected with a plurality of first mass plate 6, the outer surface of center shaft 5 is slidably connected with second mass plate 7, and the number of second mass plate 7 is provided with two groups, first mass plate 6 and second mass plate 7 are provided with fastening mechanism, the inside of support 2 is provided with buffer mechanism.

[0027] Through the above technical scheme, the device is a central symmetry structure, a plurality of first mass plate 6 and two groups of second mass plate 7 and fixed shaft 8 and corresponding nut 9 jointly form mass block, as shown in Figure 2 The center shaft 5 is mainly used for supporting and guiding, and the center shaft 5 is inserted into the center hole of the mass block. After the mass block is positioned, the position of the mass block on the center shaft 5 is locked. When the main structure vibrates, the mass block in the device moves with the main structure. However, due to the large mass, a large inertial force is generated, thereby absorbing the vibration energy of the main structure when the main structure vibrates, reducing the vibration response of the main structure. The spring shock absorber 12 uses viscous liquid. When the mass block moves relative to the main structure, the viscous material generates shear stress, thereby generating resistance. By resisting the movement of the mass block, mechanical energy is converted into heat energy or other forms of energy for dissipation, thereby reducing the vibration amplitude of the main structure.

[0028] Specifically, the fastening mechanism includes a fixed shaft 8 movably arranged inside the first mass plate 6 and the second mass plate 7, and the number of the fixed shaft 8 is two groups. The two groups of fixed shafts 8 are symmetrically distributed on the first mass plate 6 and the second mass plate 7.

[0029] Through the above technical scheme, a plurality of first mass plate 6 and two groups of second mass plate 7 and fixed shaft 8 and corresponding fixed nut 9 jointly form mass block, wherein the second mass plate 7 has two groups, respectively located at the outermost side, and the first mass plate 6 has multiple groups, at the inner side (compared with the second mass plate 7).

[0030] Specifically, the two ends of the fixed shaft 8 are threadedly connected with the nut 9, and the two ends of the fixed shaft 8 are designed as threaded structures.

[0031] Through the technical scheme, the first mass plate 6 and the second mass plate 7 are connected together, and then two fixing shafts 8 pass through corresponding first through holes 17 and second through holes 19, the fixing shafts 8 are in threaded structures at two ends, and cooperating with nuts 9 makes the whole fixing block fixed as a whole.

[0032] Specifically, the buffer mechanism includes four groups of first recessed plates 10 fixedly connected to the outer surface of the support 2, and first inner shafts 11 are fixedly arranged on the inner sides of the four groups of first recessed plates 10.

[0033] Through the technical scheme, the four groups of first recessed plates 10 arranged on the support 2 are opposite to the second recessed plates 13 arranged on the second mass plate 7, and the two are connected through the spring shock absorber 12.

[0034] Specifically, the outer surface of the first inner shaft 11 is rotationally connected with the spring shock absorber 12, and the two ends of the spring shock absorber 12 are provided with connecting holes.

[0035] Through the technical scheme, in the spring shock absorber 12, the spring can convert the energy into the elastic potential energy of the spring when the stacking machine system vibrates, and provide elasticity for the mass block, so that the mass block can generate relative motion, and the spring can obtain different initial stiffness by twisting the cover body, and different stiffness can help to adjust the maximum displacement generated by the mass block when vibrating.

[0036] Specifically, the outer surface of the second mass plate 7 is fixedly connected with the second recessed plate 13, and the number of the second recessed plate 13 is four groups, and the inner sides of the four groups of second recessed plates 13 are fixedly provided with second inner shafts 14, and the outer surface of the second inner shaft 14 is rotationally connected with the end of the spring shock absorber 12 away from the first inner shaft 11.

[0037] Through the technical scheme, after the mass block, the center shaft 5 and the spring shock absorber 12 and other components are connected, the center shaft 5 passes through the linear shaft sleeve 3 and is installed on the support 2, and the linear shaft sleeve 3 mainly plays a guiding role, so that the vibration direction of the mass block is always along the axial direction when vibrating.

[0038] Specifically, the outer surface of the first mass plate 6 is fixedly connected with the boss 15, the outer surface of the first mass plate 6 is provided with the first positioning hole 16, and the inner diameter of the first positioning hole 16 is the same as the diameter of the boss 15.

[0039] By the above technical scheme, the large circular hole in the middle of the first mass plate 6 is used to install the center shaft 5, and the unique mounting point is the design of the first positioning hole 16 and the boss 15. When multiple first mass plates 6 are installed together, two first mass plates 6 can be embedded into each other after being rotated by 180°, so that the plates can be determined to have two degrees of freedom, only allowing axial straight movement and rotation along the joint surface. The advantage of this design is that the optimal mass ratio of the damper mass block of the double-column stacker is about 1%, so that the device meets the variable mass requirement of the mass block for stackers with different total masses.

[0040] Specifically, the outer surface of the first mass plate 6 is provided with a first through hole 17, and the inner diameter of the first through hole 17 is the same as the diameter of the fixed shaft 8. The number of first through holes 17 is two groups.

[0041] Through the above technical scheme, the first through hole 17 on the left and right of the first mass plate 6 is used to install the fixed shaft 8, so that the fixed shaft 8 passes through and cooperates with the nut 9 to tightly fit the first mass plate 6 and the second mass plate 7 together.

[0042] Specifically, the outer surface of the second mass plate 7 is provided with a second positioning hole 18, and the inner diameter of the second positioning hole 18 is the same as the diameter of the boss 15.

[0043] Through the above technical scheme, the difference between the first mass plate 6 and the second mass plate 7 is that the second recessed plate 13 is welded on one side surface of the second mass plate 7. There are two second mass plates 7 in the entire structure, which are distributed on both sides of the mass block, so as to facilitate the connection of the spring shock absorber 12 and the mass block.

[0044] Specifically, the outer surface of the second mass plate 7 is provided with a second through hole 19, and the inner diameter of the second through hole 19 is the same as the diameter of the fixed shaft 8.

[0045] Through the above technical scheme, the inner diameters of the first through hole 17 and the second through hole 19 are set to be the same as the diameter of the fixed shaft 8, so that the fixed shaft 8 can pass through. The inner diameters of the first positioning hole 16 and the second positioning hole 18 are the same as the diameter of the boss 15, so that the boss 15 can be inserted.

[0046] Working principle: the principle of reducing the movement of the stacker is that when the main structure vibrates, the mass block in the device will move with the main structure, but due to its large mass, it will generate a large inertia force, thereby absorbing the vibration energy of the main structure when the main structure vibrates, reducing the vibration response of the main structure. Among them, the spring shock absorber 12 will generate a relative displacement of the piston rod, piston, shock absorber cylinder, shock valve and oil seal when subjected to impact force, which is the main energy dissipation device in the device. The piston rod will move with the movement of the external structure, driving the piston to move reciprocatingly in the cylinder. The movement of the piston makes the viscous fluid in the cylinder pass through the preset throttle channel on the piston. Due to the viscosity of the viscous fluid itself, the fluid will generate a damping force related to the flow velocity in the flow process. The direction of this damping force is opposite to the direction of the piston movement, which can effectively hinder the movement of the piston, and also plays a role in inhibiting the vibration of the external structure. And in this process, mechanical energy is converted into heat energy, and finally the vibration energy is dissipated, so that the vibration amplitude of the structure is reduced. Therefore, through the ingenious design in the application, the natural frequency is matched with the structure vibration frequency, so that the inertia force opposite to the direction of structure vibration can be generated when vibration occurs, effectively offsetting the vibration energy and significantly reducing the vibration amplitude of the structure.

[0047] In summary, the device is mainly suitable for double-column stackers. For double-column stackers of different heights and widths, the initial stiffness and support force can be changed by adjusting the pre-compression amount of the spring, so as to obtain an adjustable maximum displacement of the mass block movement. By increasing the number of mass blocks, double-column stackers of different weights can be matched. The viscous damper can be replaced to adjust the damping ratio to adapt to the system, reduce the vibration amplitude of the walking direction of the double-column stacker, and make the whole reach a static state in a short time, reduce the cost of using other damping devices, and improve the stability and life of the equipment.

[0048] Although the embodiments of the application have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the application, and the scope of the application is defined by the appended claims and their equivalents.
