The utility model has been announced the movable voussoir safety tongs of a kind of building hoist list, it is characterized in that, comprises safety block, velocity limiter, flip flop equipment clutch assembly, travel switch; Described velocity limiter connects flip flop equipment clutch assembly, described flip flop equipment clutch assembly can be controlled travel switch, described safety tongs comprises the safety tongs pedestal being fixedly installed on sedan-chair cage, in pedestal, be provided with mutually involutory quiet voussoir, moving voussoir, between safety tongs pedestal contiguous block and voussoir, be equipped with ball plate, voussoir inner arc wall is right against standard knot steel pipe, is built-in with quiet voussoir spring and adjusting bolt between quiet voussoir downside and caliper lower wall, and moving voussoir lower end connects flip flop equipment clutch assembly.The utility model is simple in structure, and practicality easy for installation is used safety tongs and rack-and-pinion falling protector to use in order to reduce construction hoist falling-proof risk simultaneously, reduces the security risk of construction.
Description
Technical field
The utility model relates to construction machinery and equipment, is specially the movable voussoir safety tongs of a kind of building hoist list.
Background technology
At present, the construction elevator of use generally adopts rack-and-pinion falling protector to prevent elevator tenesmus at the construction field (site), but accident happens occasionally, and elevator tenesmus can cause extremely severe safety misadventure.
Summary of the invention
The utility model object provides a kind of building hoist list movable voussoir safety tongs for prior art shortcoming.
The utility model for achieving the above object, adopts following technical scheme: the movable voussoir safety tongs of a kind of building hoist list, comprises safety block, velocity limiter, flip flop equipment clutch assembly, travel switch, described velocity limiter connects flip flop equipment clutch assembly, described flip flop equipment clutch assembly can be controlled travel switch, described safety block comprises the safety tongs pedestal being fixedly installed on sedan-chair cage, in pedestal, be provided with involutory quiet voussoir mutually, moving voussoir, between caliper and voussoir, be equipped with ball plate, voussoir inner arc wall is right against standard knot steel pipe, between quiet voussoir downside and caliper lower wall, be built-in with the position that quiet voussoir spring and adjusting bolt regulate him, moving voussoir lower end connects flip flop equipment clutch assembly, spring one end is fixed on wedge groove lid bottom, the other end connects ball plate.
Preferably, described safety block is comprised of safety tongs pedestal and moving voussoir assembly, quiet voussoir assembly three parts.
The utility model beneficial effect: the utility model is simple in structure, practicality easy for installation, having solved existing building hoist only has rack-and-pinion falling protector to prevent the limitation of elevator tenesmus, reduces the security risk of constructing.
Accompanying drawing explanation
Lower Fig. 1 is safety block constructional drawing of the present utility model.
The overall schematic diagram that lower Fig. 2 is building hoist of the present utility model.
Lower Fig. 3 is building hoist section drawing of the present utility model
The specific embodiment
The movable voussoir safety tongs of a kind of building hoist list comprises safety block 15, velocity limiter 16, flip flop equipment clutch assembly 12, travel switch 14, described safety block 15 comprises the safety tongs pedestal 2 being fixedly installed on sedan-chair cage, in in pedestal, be provided with involutory quiet voussoir 6 mutually, moving voussoir 5, between caliper and voussoir, be equipped with ball plate 8, it contributes to wedge slides, voussoir inner arc wall is right against standard knot steel pipe 1, between quiet voussoir 6 downsides and caliper lower wall, be built-in with quiet voussoir spring 9 and adjusting bolt 10, adjusting bolt is used for regulating the position of quiet voussoir spring, moving voussoir 5 lower ends connect flip flop equipment clutch assembly 12, spring 3 one end are fixed on wedge groove and cover 4 bottoms, the other end connects ball plate, described velocity limiter 16 is arranged on roller, by steel cable 11, connect flip flop equipment clutch assembly 12, when steel cable 11 Negotiation speeds on roller surpass restriction speed, velocity limiter 16 can be strained steel cable 11, steel cable 11 surface tension can trigger clutch assembly 12 again after becoming greatly, make its shutoff stroke switch 14, travel switch cuts out and means that lift loop disconnects, steel cable no longer draws 13 motions of sedan-chair cage, if at this moment sedan-chair cage also could not be put and stop, the moving voussoir 5 that flip flop equipment clutch assembly can trigger safety tongs so inwardly pushes, in voussoir uphill process, can produce pressure, compressing steel pipe is parked on standard knot steel pipe sedan-chair cage folder.
In addition to the implementation, the utility model can also have other embodiments, all employings to be equal to the technical scheme of replacement or equivalent transformation formation, all drops on the protection domain of the utility model requirement.
