Embodiment

For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate Accompanying drawing describes in detail as follows：

Referring to Fig. 1, a kind of anti-fall device of integrated form elevating scaffold, including it is affixed with guider main body 1-1 Troffer 2-1 and anti-fall block 2-2, the Troffer 2-1 opening are towards scaffold support body 1-2, the anti-fall block 2-2 is arranged in the Troffer 2-1, is provided with and is indulged close to the centre of scaffold support body 1-2 sides in the anti-fall block 2-2 To groove 2-3, it is provided with the longitudinal fluting 2-3 and excites shift fork 2-4, the bottom for exciting shift fork 2-4 and described anti- Pendant block 2-2 bottom is connected by bearing pin 2-5 with the Troffer 2-1, the upper end of the anti-fall block 2-2 with it is described Troffer 2-1 bottom plate is connected by reset tension spring 2-6, and the anti-fall block 2-2 is provided with upper limit and lower limit, described anti- The upper limit 2-10 and the anti-fall block that fall block lower limit 2-7 are fixed on guider main body 1-1, described to excite Shift fork 2-4 is provided with lower limit, and the lower limit 2-8 for exciting shift fork is arranged on the anti-fall block 2-2.

In the present embodiment, the reset tension spring 2-6 is connected by screw rod 2-9 with the Troffer 2-1, existing to facilitate The anti-fall block in field carries out fine position.

When scaffold support body 1-2 is lifted, ladder bars, which drive, excites shift fork 2-4 to be swung up, and after ladder bars pass through, excites and dials Pitch 2-4 with ladder bars to depart from, resetted in the presence of reduction torsion spring and its own gravity to lower swing.In this process, it is anti-fall Block 2-2 is not contacted with ladder bars, and standing state is kept in the presence of reset tension spring 2-6.

When scaffold support body 1-2 declines or fallen, ladder bars, which drive, excites shift fork 2-4 to rotate down, and excites shift fork 2-4 to lead to Crossing its lower limit 2-8 drives anti-fall block 2-2 to rotate together, and reset tension spring 2-6 gradually elongates with the rotation of anti-fall block, when When anti-fall block 2-2 turns to horizontal level, stopped operating under the lower limit 2-7 effects of anti-fall block, it is horizontal below ladder bars, Card stops scaffold support body 1-2.

Although preferred embodiment of the present utility model is described above in conjunction with accompanying drawing, the utility model is not Above-mentioned embodiment is confined to, above-mentioned embodiment is only schematical, is not restricted, ability The those of ordinary skill in domain is not departing from the utility model aims and claimed under enlightenment of the present utility model In the case of scope, many forms can also be made, these are belonged within the scope of protection of the utility model.
