[0020] It is to be understood that the terms "first" and "second" and similar relating terms are used merely to distinguish one entity or action from another, and do not necessarily require or imply any such actual relationship or order between such entities or actions. Also, the terms "comprising", "containing" or any other similar words are intended to encompass non-exclusive inclusion, so that a process, method, article or apparatus including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent in such process, method, article or apparatus. Without more limitation, the element defined by the phrase "comprising a" does not exclude the presence of additional identical elements in the process, method, article or apparatus including the element.

[0021] The features and performances of the present application will be further described in detail below in connection with the embodiments.

[0022] Please refer to Figures 1-3 A stacker lifting platform follow-up brake device, as shown in Figure 1 , comprising a safety clamp 3, a sliding chute mechanism 1 and a sliding block mechanism 2, the sliding chute mechanism 1 is fixedly connected with the lifting platform, the sliding block mechanism 2 is arranged at the middle part of the sliding chute mechanism 1, and the sliding block mechanism 2 can move along the sliding chute of the sliding chute mechanism 1; the safety clamp 3 and a safety clamp trigger mechanism 4 are arranged at the middle part of the sliding block mechanism 2; at least four guide wheels 7 are further arranged on the sliding block mechanism 2, the guide wheels 7 are clamped on the brake guide rail 5 of the stacker column, and there is a gap between the guide wheels 7 and the brake guide rail 5 and between the safety clamp 3 and the brake guide rail 5.

[0023] The safety clamp 3 and the sliding block mechanism 2 are fixedly connected by bolts.

[0024] The gap distance between the guide wheels 7 and the brake guide rail 5 is slightly smaller than the gap distance between the safety clamp 3 and the brake guide rail 5. The gap between the guide wheels 7 and the brake guide rail 5 is determined by the gap between the safety clamp 3 and the brake guide rail 5, so as to ensure that there is a certain gap between the safety clamp 3 and the brake guide rail 5 when the guide wheels 7 contact the brake guide rail 5.

[0025] As shown in Figure 2 , the sliding block mechanism 2 further comprises a sliding seat 6, and the at least four guide wheels 7 are arranged on the sliding seat 6, and the sliding seat 6 is provided with mounting holes connected with the safety clamp 3.

[0026] The safety clamp trigger mechanism 4 is arranged above the safety clamp 3 and connected with the safety clamp brake wedge, and when the lifting platform is in an out-of-control state, the related overspeed or rope breakage detection device transmits the brake action to the safety clamp 3 brake wedge through the safety clamp trigger mechanism 4.

[0027] As shown in Figure 3As shown, the sliding block mechanism 1 includes a base 8 and a pressing block 9, the base 8 is fixedly connected with the stacker lifting platform as a whole, and the pressing block 9 is connected with the base 8 through bolts.

[0028] The number of the pressing block 9 is four, and the pressing block 9 is arranged beside the sliding block mechanism 2.

[0029] The pressing block 9 is fixed on the sliding block mechanism 1 from four directions.

[0030] The sliding block mechanism 1 provides guidance and support for the sliding of the sliding block mechanism 2 and the safety clamp 3.

[0031] When the stacker lifting platform is in normal operation, the guide wheel 7 of the follow-up brake device is always in contact with the brake guide rail 5, and the safety clamp 3 is driven to slide along the trend of the brake guide rail 5, so as to ensure that the gap between the safety clamp 3 and the brake guide rail 5 is constant. When the lifting platform is in an out-of-control state, the related overspeed or rope breakage detection device transmits the brake action to the safety clamp brake wedge through the safety clamp trigger mechanism 4, so that the safety clamp 3 is clamped on the brake guide rail 5, and then the sliding block mechanism 2 transmits the brake force to the lifting platform, so that the lifting platform stops moving.

[0032] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the technical concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
