Overload or slack rope；Two travel switches are mounted on travel switch bracket on the position of upper and lower ends, travel switch touching
Sensing chip issues stop signal, and travel switch bracket is vertically installed on loading platform vertical plate with screw；When loading platform zero load,
The spring is in compressive state；When loading platform operation, the c-type disc spring and spring are in compressive state；Work as synchronous belt
When fracture or relaxation, the c-type disc spring and spring are restored rapidly by compressive state；When loading platform overload, the loading platform connects
Fishplate bar drives sensing chip to move upwards, and upper stroke switch touches sensing chip, and all motors of piler stop working.
The anti-fall device includes eccentric glue coating wheel, eccentric bearing block, shift lever axis, driving gear, spring, rack gear and rack gear
Mounting base, rack gear driving lever and anti-fall drive rod；The anti-fall drive rod is screwed (right in the side of loading platform connecting plate
Side)；The horizontal shift lever axis is inserted on loading platform vertical plate, and is fixed with the method for welding；Rotatable rack gear driving lever with
And the plain washer for preventing rack gear driving lever from deviating from is mounted on shift lever axis, the plain washer is screwed on shift lever axis, rack gear
Driving lever one end is contacted with anti-fall drive rod, and the other end is fixed on rack gear lower end, can be on carry-over bar by the rotation of rack gear driving lever
Lower movement；The rack gear is mounted on loading platform vertical plate by rack gear mounting base, on rack gear installation can Rapid reset spring,
The lower end of spring is fixed on rack gear；Driving gear is mounted on one end of the axis of eccentric glue coating wheel, and eccentric glue coating wheel passes through bearing
It is mounted on eccentric bearing block and integral installation is on loading platform vertical plate, the driving gear and eccentric glue coating wheel pass through loading platform
Vertical plate separates；When the rack gear driving lever band carry-over bar moves upwards, rack gear is first engaged with driving gear, as rack gear is transported upwards
Dynamic, driving gear starts to rotate, and eccentric glue coating wheel is driven to rotate together.
When loading platform normal operation, the c-type disc spring and spring are in compressive state, and rack gear and driving gear are in non-
Meshing state, the bias glue coating wheel are not contacted with piler column；When loading platform falls suddenly, the c-type disc spring and bullet
Spring is restored by compressive state, and the lower travel switch touch sensing piece, all motors of piler are out of service, while anti-fall drive rod
It is upward to stir rack gear driving lever, rack gear driving lever band carry-over bar is upward, engages rack gear with driving gear, is further driven to eccentric encapsulated
Wheel rotation, makes eccentric glue coating wheel moment locking piler column, prevents loading platform from falling；It is described when loading platform restores normal
Loading platform connecting plate drives anti-fall drive rod upward, and the spring being mounted on rack gear restores rapidly, drives the rack gear downward, institute
The rotation of rack drives driving wheel opposite direction is stated, glue coating wheel and piler column is made to be in contactless state, loading platform normal operation.
The configuration of the present invention is simple, high sensitivity, stability is high, is easy for installation and maintenance.It can effectively avoid because of synchronous belt
Light duty platform falls caused by fracture or synchronous belt sag, has good overload protection function, effectively increases piler
The safety of production operation.
