Technical field
The utility model relates to building operations auxiliary equipment, particularly a kind of for scaffold safety supports location and anti-fall device.
Background technology
At present, China is high-rise and super highrise building is more and more, in to its external wall construction process, mostly adopt attachment type raise scaffold, but scaffold is in the process of climbing or decline, the problem that there will be unavoidably skids hurtles down, for fear of this class accident occurs, scaffold has been carried out to many anti-fall designs, but because design is unreasonable, or because of complex structure, product cost is relatively high, and supporting and location and the anti-drop device of attachment type raise scaffold are that separately design or device are more complicated mostly.
The utility model that for example application number is 201220752022.X discloses a kind of anti-drop device of hoisting scaffold, and the utility model anti-drop device comprises casing and anti-fall locating wheel; Casing comprises the basic part connecting with building, the plate of two sides and middle plate, anti-fall locating wheel is arranged on by rolling bearing in the groove of anti-fall plate, and anti-fall locating wheel is that an anti-fall balancing point vertical with axle center is installed on a cylinder, is installed with square fixture block on anti-fall balancing point.This anti-drop device is structure as a whole, and adopts the vertical body of wall of bolt directly fixing, and dismounting must entirety be carried out, and the reusable part parts of anti-drop device cannot be reused, and said structure cannot use at irregular metope simultaneously, and the scope of application is limited.
The patent of invention that and for example application number is 201110390236.7 discloses a kind of lifting false work location and anti-drop device automatically, comprise lifting false work and automatically locate and anti-drop device, lifting false work comprises attached wall fastening devices, guide rail and support body, attached wall fastening devices is provided with gripper shoe, automatically location and anti-drop device comprise the support and the curved bar that are arranged on guide rail, curved bar is provided with the first cantilever and the second cantilever, the first cantilever is connected with support by the first spring, the second cantilever is kept out in gripper shoe, and the second cantilever is provided with backing pin; On support, be also provided with the second spring, the second spring is connected with the balancing weight that blocks backing pin.Although this invention lifting false work has again anti-fall effect, its structure relative complex in having supporting positioning action.
Summary of the invention
For overcoming the above-mentioned shortcoming of prior art, scaffold location and anti-drop device that the utility model provides a kind of modular assembly to install, this device detachable component can directly be reused, and saves cost, simultaneously safety is higher, and can automatically locate and anti-fall.
The utility model solves the technical scheme that its technical problem adopts: a kind of scaffold is location and anti-drop device automatically, comprise pedestal, linking arm 4 and anti-fall locating wheel, pedestal is mainly made up of base plate 1, epipleural 2 and lower side panel 3, on base plate 1, be provided with bolt hole, be fixed on body of wall by through-wall bolt; Two blocks of epipleurals 2 are parallel to each other, are vertically fixed on the both sides on base plate 1 top; Two blocks of lower side panels 2 are parallel to each other, are vertically fixed on base plate 1 bottom by middle position.
The square structure that described linking arm 4 is inner hollow, is provided with circular sleeve 5 in one end of length direction, and circular sleeve both sides are provided with the guide wheel 7 to cone transition by cylinder; Two linking arms are parallel to each other, the side that circular sleeve is relative is provided with opening 6, the one end of not establishing circular sleeve 5 is fixed on the base plate 1 between epipleural 2 and lower side panel 3, and clamps setting by epipleural 2 and lower side panel 3, and between two linking arms 4, limited block 8 is set.
Anti-fall locating wheel is arranged between two lower side panel 3 tops by the rolling bearing 10 on it, on anti-fall locating wheel, be provided with baffle plate 11, anti-fall plate 12 and striker 13, baffle plate 11 is parallel with anti-fall plate 12 upper surfaces, soffit is cam structure, rolling bearing 10 is between baffle plate 11 and anti-fall plate 12, form lever rotation formula, striker 13 on cam structure and and anti-fall plate 12 between angle be 50～60 degree angles, striker 13 can regulate its length by nut 14.
Preferably, 13 one-tenth 55～60 degree angles of anti-fall plate 12 and striker.
Operating principle: pedestal is fixedly mounted on body of wall by bolt, again linking arm 4 is in place, support body moves up and down in the circular sleeve 5 of linking arm, when needs are anti-fall, back-moving spring 18 is oblique drop-down, when scaffold ladder rising or decline, ladder on support body can make anti-fall plate 12 rotate after touching striker 13, but because speed is slow, above second ladder arrives anti-fall plate 12 time, anti-fall plate resets under back-moving spring 18 effects, can not affect rising or the decline of scaffold; In the time of scaffold fast-descending, the movement locus of anti-fall plate 12 is identical, but because ladder declines fast, before anti-fall plate 12 does not also reset, upper level ladder has been fallen on the bearing surface of anti-fall plate, and limited block 8 blocks baffle plate 11 and make anti-fall locating wheel reach balance, realizes anti-fall.
Will exchange hauling power device after scaffold is elevated to certain position time, manually move back-moving spring 18 to lateral attitude, under the acting in conjunction of back-moving spring 18 and limited block 8, anti-fall plate 12 bearing surfaces are at any time in the bearing position to ladder, for locating the in the situation that of draw-gear useless, not needing has other supporting facility again.
the utlity model has following beneficial effect:1. because pedestal separates setting with linking arm, pedestal is arranged separately on body of wall, and in once constructing, both can reuse as required, reduce construction cost, strengthen safety simultaneously.
2. the sleeve on two linking arms plays position-limiting action to scaffold, is used in conjunction with guide wheel, has ensured that scaffold can steady, smooth and easy operation, avoids causing danger and the damage of sliding friction to equipment because scaffold rocks, and increases application life.
3. judge the speed of scaffold by the striker that arranges on anti-fall locating wheel and back-moving spring; avoid impact normally slowly to climb or decline process; judge that whether climbing speed is abnormal fast simultaneously; excessive velocities; anti-fall plate on anti-fall locating wheel is drawn in the rising passway of scaffold and blocks scaffold, prevents that scaffold from falling fast.
4. anti-fall locating wheel Integral design, improves safety, ensures safety.Under the acting in conjunction of back-moving spring and limited block, anti-fall plate bearing surface can be at any time in the bearing position to ladder, for locating the draw-gear useless in the situation that, without there being other supporting facility again.
