Band linkage telescopic wall wheel platform
Technical field
The utility model relates to a kind of window cleaning equipment assembly, particularly a kind of band linkage telescopic wall wheel platform.
Background technology
The flexible wall wheel of current window cleaning machine platform is retracted simultaneously and stretches out, so be provided with the outside vertical surface of building protruding ornamental strip for every alternating floor, in the lifting process of the every one deck of platform, operating personnel need the flexible wall wheel on platform to retract simultaneously, platform is made to depart from outside vertical surface of building, be affixed on the alien invasion of building by wall wheel again after platform and integrally is by ornamental strip, such platform easily occurs that platform knocks ornamental strip, and there is certain potential safety hazard in lifting platform process.
Summary of the invention
The purpose of this utility model is a kind of band of design linkage telescopic wall wheel platform.
To be solved in the utility model is that the wiping window platform used at present easily knocks the ornamental strip of outside vertical surface of building and there is the problem of potential safety hazard in lifting process.
For realizing the purpose of this utility model, this has the technical scheme of employing to be: a kind of band linkage telescopic wall wheel platform comprises platform, platform vertical rod, described platform is hung in platform vertical rod, be provided with flexible by wall mechanism in platform, described stretching comprises upper pendulum bar by wall mechanism, draft link, gangbar, upper wall wheel, lower wall wheel, upper free bearing, lower free bearing, interlock free bearing, described upper pendulum bar inner by upper free bearing and gangbar hinged, described gangbar lower end by lower free bearing and draft link the inner hinged, be articulated with on interlock free bearing in the middle part of described gangbar, described upper wall wheel is located at the top of upper pendulum bar and is stretched out in platform upper avris, described lower wall wheel is located at the top of draft link and is stretched out in platform lower avris.
The utility model has the advantages that: the utility model is by the effect of interlock fork, make the operating personnel of platform when regulating upper pendulum bar, draft link links with it, thus one is affixed on elevation of building to make wall wheel or lower wall wheel remain, ensure that the steady lifting of platform, effectively prevent the ornamental strip clashing into outside vertical surface of building, elevating safety.
