Connect the two ends of block.
Compared with prior art, this utility model devises a kind of elevator anti-shearing drop device, by signal processor
Receive the cut-off signal that door electrical-mechanical is got an electric shock, signal processor controlled motor starts, motor drives swing arm to rotate, swing arm winding is even
Splicing pulls spring assembly；Spring assembly pulls pull bar upset, and pull bar drives inserted link to move to rail clamp plate by insert rod connector；
It is connected finally by the jack in rail clamp plate and inserted link, thus lift car is stopped at rail clamp plate corresponding flat bed position
Put, play the effect preventing elevator shearing from falling, improve safety when elevator uses.Additionally, this utility model is also provided with
Ear and spring contiguous block composition spring assembly are drawn in connecting spring, back-moving spring, connection, and during flat bed latched position, connecting rope is passed through to draw
Tight spring pulls pull bar, and pull bar one end pulls connecting spring, makes back-moving spring and connecting spring all stretch generation elastic force；Work as needs
When releasing flat bed locking startup elevator, swing arm reversely rotates and unclamps connecting rope, in the reply masterpiece of connecting spring and back-moving spring
With under, pull bar resets, and inserted link leaves rail clamp plate, convenient use；By arranging 4 latch element, connecting rope relatively is symmetrical
And pull bar symmetrically, makes the both sides of lift car all be connected with rail clamp plate by 2 inserted links relatively, and two inserted links are relatively
Guide rail is symmetrical, thus balancing the stress on inserted link, rail clamp plate and guide rail, improving stability during flat bed locking, improving further
Safety.Therefore, this utility model can not only prevent shearing from falling, and also has the advantages that safety is good and easy to use.
