Abstract
The utility model provides an anti-falling safety device. The safety device comprises a pincers body housing, a wedge block and a pedestal; a connecting lever is arranged between the pincers body housing and the wedge block; an eccentric locking block and a straight plate locking block are arranged in the pincers body housing; the eccentric locking block is fixed in the pincers body housing via a central shaft; a cylinder is welded on one side of the eccentric locking block; a pull spring is fixed on the other end passing through the pincers body housing of a pulling spring connecting rod; the other end of the pull spring is fixed on the pedestal; one side of the straight plate locking block is fixed on the right side wall in the pincers body housing; a saddle weight is arranged in the wedge block; and rail grooves are arranged in upper and lower ends of the pincers body housing arranged between the eccentric locking block and the straight plate locking block. The safety device is advantaged by simple structure, safety and reliability.
Description
Technical field
The utility model relates to a kind of anti-falling safety device, is applied to goods steel rope elevator.
Background technology
Why building hoist can move in safe manned loading, mainly because it has been equipped with anti-falling safety device, greatly improve safety factor, construction site goods is widely used with elevator rail is at present pipe and angle steel, it is little that channel-section steel does track, thereby with channel-section steel do track without the anti-falling safety device that matches, be unfavorable for safety in production and build.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of anti-falling safety device of simple in structure, safety and stability.
The purpose of this utility model provides a kind of anti-falling safety device, comprise: housing, saddle weight shell, base, on described base, be provided with housing, saddle weight shell, between described housing and saddle weight shell, be provided with and be connected lever, described enclosure interior is hollow shape, described enclosure interior is provided with eccentric lock dog, straight plate lock dog, described eccentric lock dog is fixed on enclosure interior by center shaft, described eccentric lock dog one side is welded with cylinder, the described extension spring pipe link other end is fixed with extension spring through housing, the described extension spring other end is fixed on base, described straight plate lock dog one side is bolted on the right side wall of enclosure interior, described saddle weight is pressed in and connects in regulations and parameters in guard shield, housing upper and lower side between described eccentric lock dog and straight plate lock dog has rail groove.
Described connection lever one end and cylinder offset, and are pressed with saddle weight on the other end.
Described track thickness is 6-8mm.
Distance between described eccentric lock dog and straight plate lock dog is 10-12mm.
Described hex bolt has belleville spring with straight plate lock dog junction cover.
The utility model is to implement like this: base is fixed on the cage of elevator by screw, rise operation in the rail groove on hollow shell and have rail of lifter, in housing, be provided with eccentric lock dog and straight plate lock dog, eccentric lock dog is by connecting lever and saddle weight, side is connected with extension spring base by extension spring pipe link, in the time that cage normally moves, saddle weight is pressed in and connects on lever, connect lever and make eccentric lock dog rotation, between eccentric lock dog and straight plate lock dog, ensure 10-12mm distance, rail groove has the normally operation up and down of enough gaps middle (track thickness is 6-8mm), once there is disconnected rope fault, cage and safety do the movement of falling object, saddle weight is in state of weightlessness, lose connecting lever pressure, eccentric lock dog is close to straight plate lock dog under extension spring effect, guide rail both sides produce friction between eccentric lock dog and straight plate lock dog, eccentric lock dog and straight plate lock dog have hangnail, friction force can be increasing until make cage gradual braking on guide rail.
Owing to adopting technique scheme, the utlity model has following beneficial effect:
1, compact conformation, processing simple, be quick on the draw, safe reliability is high.
