DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] Example

[0021] See also Figures 1 to 4 The anti-falling device of the cargo platform in this embodiment includes a fixed tooth plate 1, a movable tooth plate 2 and a conversion assembly 3. The fixed tooth plate 1 is installed on the inner side of the stacker column 11. The working surface of the fixed tooth plate 1 is set to be serrated, and the other end away from the serrated working surface is a mounting plane, which is suitable for being installed and fixed on the inner side of the stacker column, and the serrated working surface is in the shape of an upward hook angle. The conversion assembly is movably installed on the inner side of the cargo platform hanger 21, and is rotated based on a fixed shaft 31 at one end fixedly installed on the cargo platform hanger 21. A conversion plate 32 is provided on the side of the fixed shaft 31 away from the fixed end, and three mounting holes are provided on the conversion plate 32. The middle mounting hole is rotatably connected to the fixed shaft 31, and the hole at the upper end is used to connect with the movable tooth plate 2. The working surface of the movable tooth plate 2 is set to be serrated, and the serrated working surface is in the shape of a downward hook angle, and a hinged ear is provided at the other end away from the serrated working surface. 24, the hinge ear 24 is used to hinge with the hole at the upper end of the conversion plate 32, and a guide rod 35 is fixedly set relative to the hole at the lower end of the conversion plate 32. A guide groove 34 is set at one end on the arc path of the guide rod 35 on the cargo platform hanger 21. As the conversion plate 32 rotates, the guide rod 35 slides in the guide groove 34 based on the fixed axis 31. An electromagnet assembly 33 is fixedly set on the arc path outside the outline of the guide groove 34. A magnetic block 39 is set on one side of the conversion plate 32 near the guide rod 35. The magnetic block 39 of the electromagnet assembly 33 drives the conversion plate 32 to rotate through magnetic action. A T-shaped sleeve rod 36 is set near the lower end hole of the conversion plate 32, and one end of a spring 37 is sleeved on it. A fixed block 38 is installed on the mounting plate 22 as a fixed point for installing the spring 37. The spring 37 is installed between the sleeve rod 36 and the fixed block 38, and can be stretched as the conversion plate 32 rotates.

[0022] In actual work, the electromagnet assembly 33 will not be energized, and without the influence of magnetic force, the conversion plate 32 will not move and will be tightened and limited by the spring 37 set at its lower end, and will be in a vertical state. At this time, there is a large gap between the movable tooth plate 2 and the fixed tooth plate 1, which will not affect the normal lifting and lowering operation of the cargo platform; when the detection switch detects that the descending speed of the cargo platform is abnormal, the electromagnet assembly 33 will be energized, and the magnetic block 39 will be adsorbed at this time. The conversion plate 32 will overcome the pulling force of the spring 37 and rotate under the action of the magnetic force. At the same time, the movable tooth plate 2 will approach the fixed tooth plate 1, and finally the upper hook tooth 12 and the lower hook tooth 23 of the tooth plate will be engaged, thereby stopping the downward trend of the cargo platform and playing an anti-falling role.

[0023] Through the above description, those skilled in the art can already implement it.

[0024] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model.
