[specific embodiment]

Referring to accompanying drawing, a kind of climbing frame falling proof device of the present invention, it is characterized in that: include anti-fall 1, leading truck 2, support body 3, back-moving spring 42, limited block 5, bearing pin 6, terraced bar 7, brake tooth 11, excite tooth 12 and buffer spring 41, support body 3 and leading truck 2 sliding connections, by its bearing pin 6, be loaded on rotationally on leading truck 2 for anti-fall 1, described anti-fall 1 comprises and excites tooth 12 and brake tooth 11, excite tooth 12 to be positioned at the below of brake tooth 11; Limited location piece 5 on leading truck 2, limited block 5 is positioned at the below of anti-fall 1; Glide direction on support body 3 is provided with at least two terraced bars 7; Back-moving spring 42 one end are fixed on leading truck 2, and the other end is fixed on anti-fall 1, and buffer spring 41 is installed in the other direction with back-moving spring 42, and one end is fixed on leading truck 2, and the other end is fixed on anti-fall 1.

The reset speed of anti-fall 1 depends on the elastic force of spring, and generally its reset speed is fast and wayward, and the present invention adopts buffer spring 41 and back-moving spring 42 interlocks, can control preferably and steady its reset speed.

In an embodiment of the present invention, anti-fall 1 is lamellar structure, and its planar profile is broken line, is beneficial to machining.

In an embodiment of the present invention, terraced bar 7 is the many round bars of equidistantly arranging.

The operating principle of the present embodiment:

Fig. 1-Fig. 3 is fundamental diagram of the present invention in support body 3 uphill process,

Referring to Fig. 1, along with the rising of support body 3, the terraced bar 7 on support body 3 just in time touch anti-fall 1 excite tooth 12 time, anti-fall 1 will around bearing pin 6 start counterclockwise rotation;

Referring to Fig. 2, support body 3 continues to rise, the terraced bar 7 on support body 3 leave anti-fall 1 excite tooth 12 time, back-moving spring 42 acts on anti-fall 1 with buffer spring 41 interlocks, makes anti-fall 1 to clockwise rotate lentamente, starts to reset;

Referring to Fig. 3, anti-fall 1 resets completely;

Fig. 4-Fig. 6 is fundamental diagram of the present invention in the normal decline process of support body 3,

Referring to Fig. 4, along with the decline of support body 3, the terraced bar 7 on support body 3 just in time touch anti-fall 1 excite tooth 12 time, anti-fall 1 will around bearing pin 6 start clockwise rotation; ,

Referring to Fig. 5, support body 3 continues to decline, the terraced bar 7 on support body 3 leave anti-fall 1 excite tooth 12 time, by back-moving spring 42 and buffer spring 41 interlock effects, anti-fall 1 starts to be rotated counterclockwise, and starts to reset;

Referring to Fig. 6, support body 3 continues normal speed and declines, and the next one ladder bar 7 on support body 3 does not also contact with the brake tooth 11 of anti-fall 1, and anti-fall 1 has resetted completely, now can not stop for anti-fall 1 support body 3 to continue to decline, and support body 3 can continue normal operation;

Fig. 7-Fig. 9 is support body 3 fundamental diagram of the present invention in process that falls suddenly,

Referring to Fig. 7, along with the decline of support body 3, the terraced bar 7 on support body 3 just in time touch anti-fall 1 excite tooth 12 time, anti-fall 1 will around bearing pin 6 start clockwise rotation;

Referring to Fig. 8, support body 3 continues to decline, the terraced bar 7 on support body 3 leave anti-fall 1 excite tooth 12 time, the interlock effect by back-moving spring 42 with buffer spring 41, anti-fall 1 starts to be rotated counterclockwise, and starts to reset;

Referring to Fig. 9, because support body 3 is to decline suddenly, its decrease speed is very fast, cause anti-fall 1 and also do not reset completely, next one ladder bar 7 on support body 3 contacts with the brake tooth 11 of anti-fall 1, reaches and stops support body 3 to continue to decline, and has stoped the non-normal working of support body 3.

When the support body normal speed of scaffold rises or declines, the effect of back-moving spring makes the present invention can not hinder the normal operation of support body, and when support body declines suddenly, the present invention can effectively stop the support body of scaffold to continue to decline, greatly reduce the generation of contingency.
