Description

Technical Field

[0001] The utility model relates to the technical field of counterweight adjustment, in particular to an adaptive counterweight adjustment mechanism. Background Art

[0002] The background of the adaptive counterweight adjustment mechanism can be traced back to the continuous pursuit of mechanical system performance optimization and automated control. With the continuous development of industrial technology and the increase in demand, traditional mechanical systems often cannot meet the requirements of precise control and stable operation in complex working environments. Therefore, people began to explore the use of advanced sensor technology and intelligent control systems to achieve automatic adjustment and optimization. In the past, the adjustment of mechanical systems often relied on static settings or manual operations. This method has problems such as low efficiency, slow response speed and high operator skill requirements. With the advancement of computer science and electronic technology, the adaptive counterweight adjustment mechanism has been applied and developed.

[0003] After searching, the patent number "CN216807895U" mentioned in the text that "the utility model relates to an adaptive counterweight adjustment mechanism for a boom tower crane, including a connecting rod mechanism, a hydraulic cylinder, and a counterweight block. The connecting rod mechanism includes a first connecting rod and a second connecting rod. The first connecting rod is hinged to the balance arm of the boom tower crane, the bottom end of the first connecting rod is connected to the counterweight block, the top end of the first connecting rod is hinged to the second connecting rod, and the other end of the second connecting rod is hinged to the telescopic rod end on the hydraulic cylinder. The utility model controls the extension and retraction of the hydraulic cylinder to make the connecting rod mechanism swing back and forth, so that the counterweight block is close to or away from the base, thereby When in use, the extension and retraction of the hydraulic cylinder is controlled to make the connecting rod mechanism swing back and forth, so that the counterweight block is close to or away from the base, thereby adjusting the ground pressure ratio of the foundation to be within a suitable and safe range and improving the safety of the whole machine. However, in the process of adjusting the counterweight block back and forth, the extension and retraction of the hydraulic cylinder drive the connecting rod mechanism to swing back and forth. In the process of swinging, it is inevitable that there will be a slight deviation to the left and right. After long-term use, the left and right deviations will become larger and larger, which will bring the risk of collapse to the boom tower crane.

[0035] Working principle: First, an adaptive counterweight adjustment mechanism is installed at the designated use position.

When adjusting the counterweight, the first telescopic rod 242 on one side of the left or right side can be controlled to push the second telescopic rod 243 downward. The counterweight block 33 at the lower end is subjected to downward force. At this point, the counterweight adjustment device will move in the direction of the corresponding weight increase. In the third step, the fixed base 1 is connected to the balancing base 31 through the connecting component 26, and a gyro ball 263 is installed at the lower end of the connecting component 26.

When the balancing base 31 deviates to a certain position, it can be returned to its original position by the pressure spring 265 and the pressure rod 264 to ensure the balance of the balancing base 31. In this way, the use process of an adaptive counterweight adjustment mechanism is completed.
