Description
Technical field
The present invention relates to a kind ofly for protecting the linkage of accidental movement of elevator cage safety gear, belong to elevator machine technical field.
Background technology
In recent years, there is the safety misadventure causing because of elevator faults in China much more, the injury that while wherein not closing completely with gate, car accidental movement causes the most outstanding, if passenger is broken down when turnover elevator, its consequence is exactly the shearing directly causing passenger's body, and consequence is quite serious.The safety problem of elevator enjoys social concerns; for current China's national situation; country also, improving the pressure GB standard of elevator, has wherein just increased " accidental movement of elevator cage protection " content, at elevator cage door, opens and need to prevent the lift car movement that meets accident while being more than or equal to 100mm.
In order to address the above problem; the various safety precautions about elevator in prior art, have been there are; for example: Chinese invention patent CN201320036258 has proposed a kind of lift car safety device; this device comprises level position sensor again, then level position sensor is connected with towing machine through microcontroller, shunt release, circuit breaker successively.At lift car, meet accident when mobile, shunt release is activated, and disconnects the circuit breaker of traction pusher side; Chinese invention patent application CN201110299987 discloses a kind of device that prevents accidental movement of elevator cage, it comprises the motor being arranged on sedan-chair top board, also comprise quadric linkage, connect elevator safety loop the micro-switch that automatically resets, can sway and touch described in the automatically reset litter of micro-switch and the lockplate that is fixedly connected on car guide rail; The output shaft of described motor connects the left end of described quadric linkage, and the right-hand member of quadric linkage connects the left end of litter, and the micro-switch that automatically resets is positioned at litter top; Described lockplate offers lock hole, and when described litter is when moving right, the right-hand member of litter can insert described lock hole; When described litter is when moving left, the right-hand member of litter can depart from described lock hole.Whether surprisingly existing way is all to rely on elevator electric-control system to detect velocity limiter rotation substantially, the movement if lift car meets accident, can drive the velocity limiter rotation that meets accident, at this moment electric-control system sends electric signal, thereby trigger next step mechanism, carries out locking action.
Owing to adopting electric-control system, there is the risk of the reason safety misadventures that easily the automatically controlled inefficacy of generation causes such as automatically controlled signal inefficacy and system interference.Therefore the applicant has proposed a kind of accidental movement of elevator cage safety protective mechanisms in Chinese invention patent application 201310366041.8, it comprises: a kind of flip flop equipment of identifying elevator cage door opening and a kind ofly do not meet accident under closed condition when mobile at elevator cage door, carries out executive device and a kind of linkage that makes flip flop equipment and executive device that interlock occur of locking immediately to car; Described flip flop equipment adopts mechanical type trigger architecture, and described executive device adopts latch segment formula locking structure, and described linkage adopts electric control structure.Although the flip flop equipment of described safety protective mechanisms and executive device all adopt pure physical construction, do not rely on the control circuit system of elevator, but what the linkage in this safety protective mechanisms still adopted is electric control structure, therefore still there is the malfunctioning security risk causing of automatically controlled signal, therefore require further improvement.
Summary of the invention
For the existing the problems referred to above of prior art, the present invention aim to provide a kind of adopt completely physical construction for protecting the linkage of accidental movement of elevator cage safety gear, further to improve the safety of elevator.
To achieve these goals, the present invention adopts following technical scheme:
For protecting a linkage for accidental movement of elevator cage safety gear, comprising: fixed mount, the cross section of described fixed mount be opening shaped as frame "
", at the outer wall of the vertical support of shaped as frame fixed mount, be fixed with slide rail, between the upper and lower horizontal support of shaped as frame fixed mount, be fixed with the axis of guide, on the axis of guide, be arranged with link span, on the axis of guide being positioned between horizontal support and link span, be provided with retracing spring; In link span both sides, be fixed with respectively a vertical connecting panel, at the upper and lower end of vertical connecting panel, be fixed with respectively the attaching parts A being connected with executive device; The other end of described link span is set on the vertical support and slide rail of shaped as frame fixed mount; At link span outer face, be fixed with retainer, described retainer is connected with swivel mount by rotating shaft, and described rotating shaft is provided with torsion spring; Upper surface at described retainer is connected with swinging plate, and one end of described swinging plate is fixed with the attaching parts B being connected with flip flop equipment, and the other end of described swinging plate contacts with swivel mount; Described linkage also comprises the rotation fixed stop that forms movement with described swivel mount or insert matching relationship.
