Description
Technical field
The utility model relates to door and window engineering field, relates in particular to the anti-falling apparatus of a kind of slide-lifting door safety.
Background technology
Industrial slide lifting door is also referred to as automatic slide-lifting door, electronic slide-lifting door etc., industrial slide lifting door is made up of folder high density polyurethane expanded material in the two-sided color steel, be applicable to the demanding factory building of cleanliness factor and zone isolation such as medicine, food, electronics, printing, supermarket, have good looking appearance, high strength, safe and reliable, open steadily, notable feature such as low noise, sealing are good with heat-insulating property, saving takies the factory building space and enhance productivity, because lower mounting condition and advantages of high practicability are used widely.A lot of slide-lifting doors do not have anti-drop device or some slide-lifting doors only use some simple coarse security reliabilities to be difficult to guaranteed drop-proof device in the market.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation, and is convenient for installation and maintenance quick, safe and reliable, good looking appearance, the anti-falling apparatus of long-lived slide-lifting door safety.
The utility model is achieved in that the anti-falling apparatus of a kind of slide-lifting door safety, comprise mounting bracket assembly, extension spring assembly, steel cable assembly, it is characterized in that: mounting bracket assembly is provided with the adjustable hinge sleeve assembly, the adjustable hinge sleeve assembly is provided with the anti-assembly that falls to blocking, anti-whereabouts card assembly and adjustable hinge sleeve assembly are provided with the extension spring assembly, and anti-whereabouts card assembly is provided with the steel cable assembly.
The utility model compact conformation, convenient for installation and maintenance quick, safe and reliable, good looking appearance is durable in use.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure 1, mounting bracket assembly, 2, the adjustable hinge sleeve assembly, 3, the extension spring assembly, 4, the anti-card assembly that falls, 5, the steel cable assembly.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, the anti-falling apparatus of a kind of slide-lifting door safety, comprise mounting bracket assembly 1, extension spring assembly 3, steel cable assembly 5, it is characterized in that: mounting bracket assembly 1 is provided with adjustable hinge sleeve assembly 2, adjustable hinge sleeve assembly 2 is provided with the anti-assembly 4 that falls to blocking, anti-whereabouts card assembly and adjustable hinge sleeve assembly are provided with extension spring assembly 3, and anti-whereabouts card assembly is provided with steel cable assembly 5.During concrete enforcement, the steel cable of traction door leaf is fixed on the steel cable shaft assembly during installation, and when door leaf was in closed condition, steel cable was in relaxed state, and extension spring this moment assembly is in free state, and the card of preventing falling is opened, and blocks track; When door leaf is opened, steel cable pulling steel cable shaft assembly, the steel cable shaft assembly rises, and will draw card one end of preventing falling this moment and rise, and causes the card rotation of anti-whereabouts to be packed up, the stressed stretching of extension spring assembly simultaneously, mounting bracket assembly is connected in bottom on the door leaf, and this moment, steel cable continued the steel cable shaft assembly is strengthened active force under door lifter drives, when lifting force greater than door leaf weight with when drawing high the power summation, door leaf begins to rise, and realizes opening the door action.When door leaf steel rope breaking or other reasons occur and causes accident to stop, when door leaf freely descends under the self gravitation effect, pulling force on the invar reel for rope disappears suddenly at this moment, extension spring is no longer stressed, the state that will affranchise rapidly drives the anti-card rotation of falling then rapidly, is returned to open configuration, block the sour jujube mouth on the aluminium alloys track, moment stops the door leaf tenesmus.The utility model is 1000 fault-free after tested, in track thickness effectively jam 600 KG level gates tenesmus during for 3mm, have improved the security performance at gate greatly.
