Therefore, how to avoid the inclination of the fork platform when carrying goods up and down, so as to cause uneven stress on the two sides of the ropes is an urgent problem to be solved at present.

[0003] After retrieval, the publication number CN219620035U discloses a stacker, which includes: a lifting mechanism; a loading mechanism, including a frame and two loading platforms arranged in the frame. The two loading platforms are arranged vertically. The frame is connected to the lifting mechanism, and the loading mechanism is configured to move vertically relative to the lifting mechanism. In this way, the integration degree of the stacker can be improved, thereby reducing its volume and weight, saving costs, and improving the stacking efficiency.

[0004] The above-mentioned stacker drives a rigid belt to lift through a transmission wheel to complete the lifting and moving of the loading mechanism. The design defect is that when the weights on both sides of the carried goods are different, the tensions borne by the rigid belts on both sides will be uneven, and in the long run, the rigid belts will be worn or even damaged. Summary of the Utility Model

[0005] The utility model provides a stacker, which solves the problem that when the weights on both sides of the carried goods are different in the prior art, the tensions borne by the rigid belts on both sides will be uneven, and in the long run, the rigid belts will be worn or even damaged.

[0014] The beneficial effects of the utility model are:

[0015] The utility model is provided with an inclination detection component at the connection between the upper support platform and the lifting platform. When the goods carried by the forklift telescopic mechanism on the upper part of the upper support platform are uneven in weight on both sides, the upper support platform will rotate outside the support rod through the rotating pipe, causing the side with a larger load on the upper support platform to tilt downward and compress the spring ring. When the side with the excess weight is pressed down to the contraction limit of the spring ring, the trigger button will be contacted and triggered, and the control panel will be triggered. At this time, the control panel will start the servo motor and cause the servo motor to drive the gear disc to rotate. At this time, the tightening push plates engaged on both sides of the gear disc will be engaged and driven accordingly and tightly press against the inner side of the lifting support mechanism. When the weights on both sides are different when the upper support platform is carrying goods and exceed the bearing limit of a single-sided spring ring, this design can be used to urgently brake the lifting platform and tightly press against the inner side of the lifting support mechanism through the tightening component to avoid the situation where the single-sided rope is overstressed.
