Description
Technical field
This utility model relates to a kind of stopping means, belongs to hoisting machinery technical field, is specifically related to a kind of pry type firm
Property the double stopping means of weight.
Background technology
Current electric block is commonly used position limit device and is divided two kinds: one is cutoff limit switch, and another kind is that weight is spacing
Switch；What cutoff limit switch can directly cut off in motor three-phase power biphase makes motor stalling；It is widely used at present, but
It exists that transmission link is many, fault rate is high, return stroke length, spacing inaccurate, the defect such as wiring is complicated；Heavy hammer limiting switch leads to
Cross the control power supply of cut-out contactless for hoisting thus cut off motor power and make motor stalling；Although simple in construction, easy for installation but
The most extensively apply at present, even if main reason is that and disconnecting if up catalyst main contacts adhesion heavy hammer limiting switch
Rise catalyst control power supply and still cannot make motor stalling.
Summary of the invention

Operation of the present utility model is achieved in that this utility model in normal state, and fork passes through shackle and sled
Bar is connected, and one end of fork is with short pin shaft for dumpling point, and fork is sagging under the effect of himself gravity, pulls under one end of ripping bar
Hanging down, owing to balancing weight is prized it with the dumpling point of long pin shaft, the tip of ripping bar by ripping bar, thus ripping bar is at balancing weight pressure and fork
Being in poised state under the effect of pulling force, ripping bar now is in level；Electric block hoisting heavy at crane
During, when lifting hook pulley group rises to the position of fork, lifting hook pulley group will trigger fork, in the process that suspension hook group rises
In, head on fork right-hand member rise, car with short pin shaft for dumpling point, upwards move in a circle, when fork right-hand member rising time
Waiting, the pulling force of ripping bar will be eliminated by fork, thus the holding power of balancing weight is eliminated by ripping bar, and balancing weight is in the action of gravity of self
Under along slide rail slide downward, during balancing weight slide downward, compressing fine motion is opened by the upper end of the raceway on balancing weight
The roller closed, thus trigger microswitch, thus electric block system is run；When electric block is at lower section lifting thing, suspension hook
Assembly pulley drops to when can not touch fork, and fork resets, and balancing weight is levered up by ripping bar.
The beneficial effects of the utility model are: of the present utility model by fork, ripping bar, balancing weight and microswitch
Engaged with one another, it is achieved the position that hoists the lifting hook pulley group of electric block carries out spacing, support install on swash plate 2 micro-
Dynamic switch, plays the effect of dual fail-safe, and when preventing the microswitch from can not have little trick, another microswitch can play
Protection effect；This utility model has the advantage that dual fail-safe, safety are high.
