Destruction.In the catching device of traditional additionaling power, band-type brake power is produced suddenly, i.e., carry out " bringing to a halt ", hanging basket to hanging basket 200
200 band-type brake power most produces destruction to guide frame 170 at last, so as to affect the guiding accuracy of guide frame 170.
Furthermore, due to the effect of the second elastic component 451, when two band-type brake catching devices 400 on hanging basket 200 are respectively with first
When between guide rail 171 and the second guide rail 172, the frictional force of generation is unequal, the second elastic component 451 will utilize the elastic force pair of itself
The distance between fixed voussoir 430 and mounting seat 410 are finely adjusted.So as to realize two band-type brake catching devices 400 and guide frame
Frictional force between 170 is equal, it is ensured that the producing balanced forces during tenesmus of hanging basket 200, protects the first guide rail 171 and the second guide rail
172 precision, while preventing 200 force unbalance of hanging basket and causing column 100 to produce the phenomenon that acutely rocks.
Further, it is to ensure flexibility that movable wedge 420 is slided, improves the response speed of band-type brake catching device 400.The
The first needle roller row's (not shown) is provided with one lozenges 432 or the second lozenges 422, and the rolling that is arranged by the first needle roller is rubbed
Wipe, it is possible to reduce the frictional force between fixed voussoir 430 and movable wedge 420, be easy to movable wedge 420 to be relatively fixed voussoir
430 move upwards.The second needle roller row 470 is also equipped with the bottom surface 425 of movable wedge 420, is equally used for reducing movable wedge
420 and first frictional force between elastic mechanism 440.
What is particularly worth mentioning is that, in the case where other parts are constant, movable wedge 420 and wear-resistant block need to be changed only
426 shape, you can realize compatibility of the band-type brake catching device 400 to dissimilar guide frame 170, band-type brake greatly improved anti-fall
The scope of application of device 400.Specifically, refering to Fig. 9 and Figure 10, when guide frame 170 is line slideway or trapezoidal rails, then will
The second abutting face 421 and wear-resistant block 426 in movable wedge 420 is set to planar shaped；Refering to Figure 11, work as guide frame
170 be circular guideway when, then by the second abutting face 421 in movable wedge 420 and wear-resistant block 426 be set to be recessed circular arc
Face；Figure 12 is referred to, when guide frame 170 is V-way, then by the second abutting face 421 in movable wedge 420 and wear-resistant block
The 426 V-arrangement faces for being set to projection.
