Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing.It should be noted that, the utility model accompanying drawing all adopts the form of simplification and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.
As shown in Figure 1 to Figure 3, pneumatic elevator of the present utility model, comprise with lower device: be arranged on the guide rail 20 in hoistway 10, be arranged on the turboset 30 at hoistway 10 top, the upper sealing device 40 corresponding with described turboset 30, the sedan-chair top sealing arrangement 50 corresponding with described upper sealing device 40, the car 60 affixed with described sedan-chair top sealing arrangement 50, and be arranged on the safety tongs device 70 on described car 60.Described upper sealing device 40 and sedan-chair top sealing arrangement 50 and hoistway 10 form hoistway seal cavity jointly.In addition, vacuum valve 301 is also provided with above described upper sealing device 40.
As shown in Figures 3 to 5, described safety tongs device 70 comprises: cylinder 710, pull bar 730, springing 720, slide bar 740 and contiguous block.Described contiguous block comprises the slide block 750 and side that are connected with slide bar 740 and the affixed friction shoe 760 of described slide block 750, and the opposite side of described friction shoe 760 contacts with described guide rail 20.
Particularly, the fixed end of described cylinder 710 is arranged on car 60 top and is communicated with hoistway seal cavity; The movable end of described cylinder 710 is connected to slide bar 740 by springing 720, and described slide bar 740 two ends are inserted in slide block 750; The movable end of described cylinder 710 is connected to slide block 750 by pull bar 730 simultaneously, and described slide block 750 is contacted with guide rail 20 by friction shoe 760.
Further, described cylinder 710 comprises: piston 713, piston rod 714, for accommodating piston 713 cylinder body 711 and be arranged on the cylinder end piece 712 at cylinder body 711 top.Wherein, cylinder body 711 is fixed on sedan-chair top sealing arrangement 50, cylinder end piece 712 is provided with the through hole for being communicated with hoistway seal cavity, one end and the described piston 713 of described piston rod 714 are affixed, the other end and springing 720 affixed while hinged with pull bar 730, the other end of described pull bar 730 is same with slide block 750 hinged.
Further, the passage 751 matched with slide bar 740 is provided with in described slide block 750, that is, described slide bar 740 slightly can move in passage 751, can guarantee that pull bar 730 by promoting and loosening slide block 750 and friction shoe 760, can reach the object regulating friction shoe 760 and guide rail 20 to rub.
Further, described friction shoe 760 matches near guide rail 20 end face shape and described guide rail 20 pattern.
As preferably, described springing 720 adopts spring, and elasticity is strong, and cost is low, long service life.
It should be noted that, the space that described piston 713 and cylinder body 711 and piston rod 714 are formed is in atmospheric pressure state.When pneumatic elevator normally works, the pressure in hoistway seal cavity is less than atmospheric pressure, and spring is in extended state.
Continue referring to Fig. 1 to Fig. 5, the working process of described safety tongs device 70 in pneumatic elevator is:
When pneumatic elevator normally works, pressure in hoistway seal cavity is less than atmospheric pressure, and piston 713 drives pull bar 730 upward movement, and pull bar 730 and then band movable slider 750 are along slide bar 740 to intermediary movements, make friction shoe 760 on slide block 750 away from guide rail 20, car 60 can free-running operation.When there is the fault such as air-tightness, power-off in pneumatic elevator, hoistway seal cavity pressure increases, the spring be cemented on slide bar 740 pulls piston rod 714 to move downward, piston rod 714 moves downward the friction shoe 760 that pull bar 730 is ordered about on slide block 750 and extrudes guide rail 20, thus plays brake action.
In sum, safety tongs device of the present utility model can act on hoistway guide rail when the pneumatic sexual abnormality of pneumatic elevator, and reaching slows down brakes the effect of pneumatic elevator, avoids pneumatic lift car descending speed too fast, causes casualties.
Obviously, those skilled in the art can carry out various change and modification to utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
