However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example
[0021] like Figure 1-3 As shown, the utility model provides an automatic power-off protection device for wire rope out of the groove, including a driving device and a power-off protection component, the driving device includes a driving trolley 1, a pulley 2 connected to the driving trolley 1, a lifting wire rope 3 sleeved on the pulley 2 and a hook 4 connected to the bottom end of the lifting wire rope 3, the power-off protection component includes a travel switch body 5 installed on the driving trolley 1, a traction wire rope 6 and a weight wire rope 7 connected to the travel switch body 5, and a V-shaped part movably sleeved on the lifting wire rope 3, the V-shaped part can be expanded or merged with its center point, and the bottom end of the traction wire rope 6 is connected to the center point of the V-shaped part, and the bottom end of the weight wire rope 7 is connected to one end of the V-shaped part.
[0022] In this embodiment, the travel switch body 5 includes a shell for protecting the switch mechanism and a driving rocker arm 10 in a lever structure arranged on one side of the shell. One end of the driving rocker arm 10 is interconnected with the top end of the traction wire rope 6, and the other end of the driving rocker arm 10 is interconnected with the top end of the weight wire rope 7. A counterweight block is provided at the end of the driving rocker arm 10 connected to the weight wire rope 7.
[0023] Specifically, the travel switch body 5 is an existing device commonly used in this field, and reference can be made to the travel switch model LX4-32 in the "Xiangtong" brand under Shandong Shengqi Heavy Machinery Co., Ltd., and the driving rocker arm 10 is a part of the switch, which can transmit the external force to the internal spring mechanism, and touch the movable contact to open or close the switch. The travel switch body 5 is a device that is well known and used by technical personnel in this field. This solution does not make any technical improvements to it, and the specific working principle is not elaborated in this article.
[0024] In this embodiment, the V-shaped member includes a left movable plate 8 and a right movable plate 9 movably connected to one end of the left movable plate 8. The bottom end of the traction wire rope 6 is connected to the connection between the left movable plate 8 and the right movable plate 9. The surfaces of the left movable plate 8 and the right movable plate 9 are respectively penetrated by first rope holes 11 symmetrical to each other. The outer wall of the lifting wire rope 3 is arranged in the first rope hole 11, and the lifting wire rope 3 is arranged parallel to the traction wire rope 6.
[0025] Specifically, the left movable plate 8 and the right movable plate 9 can be expanded or merged at the position connected to the traction wire rope 6, and then when the lifting wire rope 3 is out of the groove, the left movable plate 8 and the right movable plate 9 can be merged with a smaller angle, so that the position connected to the traction wire rope 6 is raised, so that the traction wire rope 6 can be moved up at the same length, prompting the driving rocker arm 10 to open the gate.
[0026] In this embodiment, a second rope hole 12 is opened at the end of the right movable plate 9 away from the connection with the left movable plate 8, and the bottom end of the weight wire rope 7 is connected to the second rope hole 12. The second rope hole 12 is arranged on the outer side of the lifting wire rope 3, and when the V-shaped part is in the unfolded state, the weight wire rope 7 is parallel to the lifting wire rope 3.
[0027] Specifically, by arranging the second rope hole 12 on the outer side of the lifting wire rope 3, the crossing phenomenon of the weight wire rope 7 and the lifting wire rope 3 is avoided, which is beneficial for the weight wire rope 7 to stably drive the driving rocker arm 10 to open or close the switch when the lifting wire rope 3 is out of the groove.
[0028] The working principle and use process of this utility model: Figure 1 As shown, the hoisting wire rope 3 is in the normal use state of the crane during the hoisting process, and as shown in FIG. Figure 2 As shown in the figure, when the lifting wire rope 3 is out of the groove, the spacing between the lifting wire ropes 3 can be reduced. When the spacing between the lifting wire ropes 3 becomes smaller, the left movable plate 8 and the right movable plate 9 can be driven to merge inward, and then when the left movable plate 8 and the right movable plate 9 are merged, the heavy hammer wire rope 7 connected to one end of the right movable plate 9 can be pulled downward, and at the same time, in conjunction with the rise of the connection between the left movable plate 8 and the right movable plate 9, the traction wire rope 6 is prompted to move upward. In this way, after the lifting wire rope 3 is out of the groove, the heavy hammer wire rope 7 pulls the driving rocker 10 to complete the opening work, causing the driving device to be powered off and unable to work normally without maintenance, thereby avoiding the problem of continuous lifting of heavy objects after the lifting wire rope 3 is out of the groove, which poses a safety hazard to personal safety or equipment.
