AI Technical Summary
The existing anti-collision structure of the lifting platform is not sensitive enough and cannot effectively avoid collisions with obstacles.
It adopts a left-right symmetrical anti-collision switch structure, and uses load sensors and strain gauges to convert the collision force into an electrical signal. The controller controls the lifting platform to stop or reverse its movement in real time to achieve anti-collision protection.
The improved collision avoidance sensitivity of the lifting platform enables it to avoid contact with obstacles in a timely manner, ensuring safety and reliability.

A new structure of anti-collision switch for lift platform, characterized in that, include: Left anti-collision switch (10), right anti-collision switch (6), left outer column (11), right outer column (5), base plate assembly (7); The left anti-collision switch (10) is located between the left outer column (11) and the base plate assembly (7), and the left outer column (11) and the base plate assembly (7) are fixedly connected together by the left anti-collision switch (10); The right anti-collision switch (6) is located between the right outer column (5) and the base plate assembly (7), and the right outer column (5) and the base plate assembly (7) are fixedly connected together by the right anti-collision switch (6); The left anti-collision switch (10) includes an upper left fixed plate (101), a lower left fixed plate (102), and a load sensor; the upper left fixed plate (101) is fixedly connected to the left inner column (9), the load sensor is fixedly connected to the upper left fixed plate (101) and also fixedly connected to the lower left fixed plate (102), the lower left fixed plate (102) is fixedly connected to the base plate assembly (7), the number of load sensors is not less than one, and it is set between the upper left fixed plate (101) and the lower left fixed plate (102). A certain deformation gap is reserved in the part where the strain gauge is pasted in the middle of the load sensor and in the upper left fixed plate (101) and the lower left fixed plate (102); The right anti-collision switch (6) includes an upper right fixed plate (61), a lower right fixed plate (62), and a load sensor. The upper right fixed plate (61) is fixedly connected to the right outer column (5). The load sensor is fixedly connected to the upper right fixed plate (61) and also to the lower right fixed plate (62). The lower right fixed plate (62) is fixedly connected to the base plate assembly (7). There is no less than one load sensor, which is set between the upper right fixed plate (61) and the lower right fixed plate (62). A certain deformation gap is reserved in the part where the strain gauge is pasted in the middle of the load sensor and in the upper right fixed plate (61) and the lower right fixed plate (62).
2. The new structure of anti-collision switch of the lifting platform according to claim 1, wherein, Includes signal line (22), the strain gauge on the load sensor is electrically connected to the controller (20) through signal line (22).
