Description

Technical Field

[0001] This invention relates to the field of material stacking equipment technology, specifically to a fly ash solidification material stacking device. Background Technology

[0002] In the fields of environmental protection and hazardous waste treatment, fly ash typically needs to be solidified into block materials before being centrally stacked and transported. In the existing technology of material stacking equipment, fly ash solidified material stacking devices usually use a simple gripping mechanism to stack the material one by one from bottom to top.

[0003] However, due to the uneven density distribution of fly ash during mixing and solidification, the center of gravity of the solidified material is easily deviated from its geometric center. When this material with a shifted center of gravity is directly lifted and stacked, it is prone to unilateral tilting. As the stacking height increases, the tilting error accumulates, eventually causing the entire stack to collapse, posing a serious safety hazard. Existing technologies often require expensive vision sensors and multi-axis robots for position correction. However, this not only significantly increases the manufacturing cost of the equipment, but also the high dust levels at the fly ash processing site make optical and electronic sensors highly susceptible to contamination and malfunction, resulting in a high equipment failure rate and extremely high maintenance costs. Therefore, we propose a fly ash solidification material stacking device. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a fly ash solidification material stacking device, which overcomes the shortcomings of the prior art, has a reasonable design and compact structure, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fly ash solidification material stacking device, comprising a channel formed by columns and side plates, characterized in that it further includes:

[0007] The lifting unit, located within the channel, includes a cylinder and a platform. The output shaft of the cylinder is connected to the center of the bottom of the platform via a ball joint.

[0008] The transmission unit is mounted on the output shaft of the cylinder and includes a sliding rod that slides laterally. A connecting rod is hinged between the sliding rod and the platform.

[0009] The material pushing unit, installed on the side plate, includes a material pushing plate. One end of the material pushing plate forms a material pushing and flattening end that extends into the channel to push and flatten the material, and the other end forms a force triggering end corresponding to the sliding rod.

[0010] The base unit, located on the side plate, is used to receive the material after it has been leveled and raised.

[0011] When the platform receives material with a shifted center of gravity and tilts downwards on one side, the connecting rod converts the downward pressure into the lateral movement of the sliding rod. The sliding rod moves laterally and abuts against the force-triggered end, causing the material-pushing end to swing into the channel to push and correct the material.

[0012] Preferably, the cylinder's output shaft is provided with cross-shaped fixing rods, which are not on the same plane.

[0013] Preferably, a groove is provided along the length of the fixed rod, and the sliding rod is slidably disposed in the groove.

[0014] Preferably, a telescopic rod is also hinged between the bottom of the platform and the output shaft of the cylinder for flexible support of the platform.

[0015] Preferably, the pushing unit further includes a pushing shaft rotatably mounted on the side plate, and the pushing plate has a bent structure and is fixed to the pushing shaft;

[0016] Preferably, a tension spring connects the back of the pusher plate to the side plate.

[0017] Preferably, the base support unit includes a base support shaft rotatably connected to the side plate, and a base support plate connected to the base support shaft; a groove is provided on the side plate, and the base support plate extends into the channel through the groove.

[0018] Preferably, a limiting frame located above the bottom support plate is fixed on the side plate, and a second positioning post is installed on the limiting frame; a vertical plate is fixed to the bottom support plate, a first positioning post is installed on the vertical plate, and a return spring is provided between the first positioning post and the second positioning post.

[0019] This invention provides a stacking device for solidified fly ash materials. It has the following beneficial effects:

[0020] 1. Utilizing the tilting gravity generated by the shift in the center of gravity of the solidified fly ash material as a power source, the platform presses down, causing the connecting rods and sliding rods to move laterally, triggering the side pusher plates to push the tilted material in the opposite direction and correct its deviation. This eliminates the need for complex electronic sensing and control systems, ensuring the material remains upright during the upward stacking process and effectively preventing the stack from tilting and collapsing.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this invention, not all of it. All other works obtained by those skilled in the art based on this invention without inventive effort are within the scope of protection of this invention.

[0030] See attached document Figures 1-7 A fly ash solidification material stacking device is disclosed. The device includes a column 1 and a side plate 11, which together form a channel for vertical stacking of fly ash solidification material. A base support unit 2 is provided on the side of the side plate 11. The base support unit 2 includes a base support shaft 21 rotatably connected to the side plate 11 and a base support plate 22 fixedly connected to the base support shaft 21. To facilitate the movement of the base support plate 22, a groove 12 is provided on the side plate 11 for the base support plate 22 to extend into the channel. The base support plate 22 extends into the channel through the groove 12, mainly used to receive and support the stacked material from the bottom. To achieve automatic reset of the base support plate 22 after being subjected to force, a limiting frame 25 is also fixedly connected to the side plate 11. The limiting frame 25 is erected above the outer side of the base support plate 22, and a second positioning post 26 is installed on the limiting frame 25. Simultaneously, a vertical plate 23 is fixed to the base support plate 22, and a first positioning post 24 is installed on the vertical plate 23. A return spring (not shown in the figure) is provided between the first positioning post 24 and the second positioning post 26. The constant force of the spring keeps the bottom support plate 22 in a horizontal blocking state that extends into the channel under normal conditions.

[0031] A lifting unit 4 is installed at the bottom of the channel. This lifting unit 4 includes a mounting plate 41 fixedly connected inside the channel. A cylinder 42 is mounted at the bottom of the mounting plate 41, and the output direction of the cylinder 42 is aligned with the vertical direction of the channel. The output end of the cylinder 42 extends upwards from the mounting plate 41 and is connected to the center of the bottom surface of the platform 43 via a ball joint, allowing the platform 43 to have multiple degrees of freedom for tilting when subjected to uneven forces. A corresponding number of telescopic rods 44 are hinged between each corner of the platform 43 and the output shaft of the cylinder 42, providing flexible support and limiting for the platform 43. Multiple fixed rods 45 are also cross-arranged on the output shaft of the cylinder 42. To avoid motion interference, the fixed rods 45 are not arranged on the same horizontal plane. A groove is formed along the length of the fixed rod 45, and a sliding rod 46 is slidably arranged within the groove, with the length of the sliding rod 46 not less than the length of the fixed rod 45. A connecting rod 47 is hinged between the end of each sliding rod 46 and the bottom surface of the platform 43.

[0032] A pushing unit 3 is also installed on the side plate 11. This unit includes a pushing shaft 31 rotatably mounted on the side plate 11, and a pushing plate 32 with a bent structure is fixedly connected to the pushing shaft 31. One end of the pushing plate 32 passes through the side plate 11 into the channel and extends towards the top of the platform 43, corresponding to the position of the material, forming a pushing end. A tension spring 33 is connected between the back of the extended plate and the side plate 11 to provide a reset torque. The other end of the pushing plate 32 enters the channel and corresponds to the movement trajectory of the sliding rod 46, forming a force-triggered end. When the solidified fly ash material is conveyed by the external conveying device and stays above the platform 43, the cylinder 42 drives the platform 43 to rise to receive the material. Considering that the internal density of the solidified fly ash material is often uneven, causing its center of gravity to deviate from the geometric center, when the platform 43 receives the material with the offset center of gravity, the eccentric gravity forces the platform 43 to tilt and press down at a certain angle around the central ball joint to the side of the offset center of gravity. At this time, the inclined downward-pressing platform 43 compresses the corresponding telescopic rod 44, and transfers the longitudinal pressure of the downward pressurization to the sliding rod 46 through the connecting rod 47. Based on the hinge geometry between the connecting rod 47 and the sliding rod 46, this longitudinal pressure is efficiently converted into a force that drives the sliding rod 46 to move laterally outward along the groove of the fixed rod 45. The outwardly moving sliding rod 46 precisely abuts against and pushes the force-triggered end at the bottom of the pusher plate 32, causing the pusher plate 32 to overcome the tension of the tension spring 33 and rotate around the pusher shaft 31. At this time, the material-pushing and leveling end at the top of the pusher plate 32 swings inward into the channel, pushing and correcting the tilted material on the platform 43 in the opposite direction, ensuring that the material maintains a correct posture during the upward process. As the cylinder 42 continues to drive the corrected material to rise, the top of the material pushes open the bottom support plate 22, that is, the bottom support plate 22 flips downward around the bottom support shaft 21. After the material passes the bottom support plate 22, the bottom support plate 22 quickly returns to a horizontal state under the spring tension. Finally, the bottom support plate 22 stably supports the material, and the platform 43 descends and resets. The above process can be repeated to achieve the stacking of materials.

[0034] The above description is only used to illustrate the technical solutions of the present invention, and is not intended to limit them. Although the present invention has been described in detail with reference to the foregoing, those skilled in the art should understand that modifications can still be made to the foregoing technical solutions, or equivalent substitutions can be made to some of the technical features.
