Description

It is straight to drive elevator anti-dropping safety device
Technical field
The invention belongs to cordless elevator field, more particularly to a kind of straight drive elevator anti-dropping safety device.
Background technology
Elevator is the important transportation link of all kinds of buildings, does not require that the linear electric motors of steel wire rope and independent Machine Room are wireless and carries The machine of liter has proposed for a long time, there is the straight drive elevator for skyscraper and mine, cost and reliability in the prior art In the presence of it is more or less the problem of.In the prior art,《It is straight to drive home lift》(The patent No.:CN201010528066.X)Patent proposes A kind of safety speed-limit protection device:By gear, rack, get rid of ball machine structure, swing-bar mechanism, torsion spring and form, get rid of ball machine structure and gear It is coaxially connected, and be connected with swing-bar mechanism, gear is run at the same speed along rack with car, and gear drives the coaxial ball machine structure that gets rid of to turn It is dynamic, drive swing-bar mechanism to control safety tongs to act by torsion spring.But there is following defect in the program:Speed limit link and execution link Part is more, mechanism is complicated, and can only unidirectional speed limit, standardization level is low, and safety tongs action is less reliable, is difficult to safeguard etc. asks Topic.
The content of the invention
Exist in the prior art:Safety tongs reliability is low and the problem of being difficult to safeguard, to solve the above problems, providing one Kind is straight to drive elevator anti-dropping safety device.
It is straight to drive elevator anti-dropping safety device, including arranged along hoistway fixation support assembly, the peace for mounting board braking rail Full pincers, the lifting wirerope-winding for triggering safety tongs are fixed on rope sheave, and rope sheave is connected to freewheel clutch by connecting shaft I One end, the other end of freewheel clutch are connected with gear connecting shaft II, and the bearing on connecting shaft I, connecting shaft II is fixed on bearing On seat, bearing block is fixed on the carrying mover of car or testing the speed in speed limit shift mechanism fixed plate for car frame, or bearing block The carrying mover of car or testing the speed in speed limit shift mechanism fixed plate for car frame are connected to by buffer spring, supported fixed The rack engaged with gear is fixed at least one side of assembly.Described freewheel clutch is unidirectional or bidirectional overtaking clutch Device.Or described freewheel clutch is centrifugal clutch.Anti-falling protection process, when car stall drops, mover is with sedan-chair Railway carriage or compartment drops, and is quickly rotated with rack meshed gears, drives freewheel clutch connecting shaft II to rotate, when rotating speed continues increase, The rotating shaft of freewheel clutch just drives outline to rotate, and the rotation of outline drives rope sheave to tense lifting steel wire by connecting shaft I Rope, safety tongs work is just triggered, the wedge clamping braking rail of safety tongs is simultaneously locked, car is stopped tenesmus.
Relative and prior art, the present invention are arranged on safety tongs in braking rail, the rope sheave of connection triggering lifting steel wire rope It is connected with freewheel clutch, freewheel clutch is connected with that can measure the gear of car speed again, so can not only quickly be made It is dynamic, and securely and reliably.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Wherein, 1 is braking rail;2 be safety tongs;3 be safety tongs fixed plate;4 be fixing bolt;5 be lifting steel wire rope;6 It is connecting shaft I;7 be rope sheave;8 be right axle bearing;9 be connecting shaft II;10 be the speed limit shift mechanism fixed plate that tests the speed;11 be fixed Bolt group;12 be freewheel clutch;13 be rack;14 be gear;15 be left shaft holder;17 be mover;18 be stator.
Embodiment
As shown in figure 1, directly drive elevator anti-dropping safety device, including arranged along hoistway fixation support assembly, for mounting board The safety tongs 2 of braking rail 1, safety tongs 2 are fixed in safety tongs fixed plate 3 by fixing bolt 4, and safety tongs fixed plate 3 is fixed On mover 17, mover 17 moves along stator 18, and the lifting steel wire rope 5 of triggering safety tongs 2 is fastened on rope sheave 7, rope sheave 7 are connected to one end of freewheel clutch 12, the other end and the connecting shaft II9 phases of gear 14 of freewheel clutch 12 by connecting shaft I6 Even, connecting shaft I6 is arranged in right axle bearing 8 by bearing, connecting shaft II9 is arranged on left shaft holder 15 by bearing, right axle The speed limit that tests the speed of mover 17 or car frame that bearing 8 and left shaft holder 15 are fixed on carrying car by fixing bolt group 11 lifts In mechanism fixed plate 10, or bearing block is connected to the mover 17 of carrying car or the speed limit that tests the speed of car frame by buffer spring In shift mechanism fixed plate 10, the rack engaged with gear is fixed at least one side of fixed support assembly.
Described freewheel clutch 12 is unidirectional or double rolling key clutch.
Described freewheel clutch 12 is centrifugal clutch.
Anti-falling protection process, when car stall drops, mover 17 drops with car, fast with the meshed gears 14 of rack 13 Speed rotation, drives the connecting shaft II 9 of freewheel clutch 12 to rotate, and when rotating speed continues increase, the rotating shaft of freewheel clutch 12 is with regard to band Dynamic outline rotates, and the rotation of outline drives rope sheave 7 to tense lifting steel wire rope 5 by connecting shaft I 6, just triggers the work of safety tongs 2 Make, the wedge clamping braking rail 1 of safety tongs 2 is simultaneously locked, car is stopped tenesmus, so as to play the purpose of safe fall-proof.
