Description
Technical field
The present invention relates to a kind of stopping means, belong to hoisting machinery technical field, be specifically related to a kind of pry type rigidity weight
The double stopping means of hammer.
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
The pry type rigidity weight that the present invention provides a kind of dual fail-safe, safety high for overcoming the deficiencies in the prior art is double
Stopping means.
The technical scheme is that the double stopping means of a kind of pry type rigidity weight, it includes crossbeam and is fixed on
Ripping bar stopping means on crossbeam:
Described ripping bar stopping means includes the connecting plate being fixed on crossbeam by lag bolt, the middle part weldering of described connecting plate
Being connected to fixing riser, the both sides of described fixing riser are welded with fixed side, and described fixed side side is provided with slide rail,
The upper end of fixing riser has been bolted protecting cover cover, and described protecting cover cover is equipped with stay bolt, the end weldering of connecting plate
Being connected to support swash plate, described support swash plate is fixed with microswitch by lag bolt, the described stay bolt other end passes
Support swash plate；
Being additionally provided with balancing weight in protecting cover cover, the two sides of described balancing weight are provided with the cunning matched with described slide rail
Road, the end face of balancing weight is provided with the raceway that the roller with microswitch adapts；
The bottom of fixing riser offer gap, the both sides of described gap are provided with fixed block, in described fixed block
Portion is equipped with long pin shaft, and the middle part of described long pin shaft is equipped with the ripping bar adapted with gap, and the side of described ripping bar is
Ladder structure of right angle, the tip of ripping bar stretches into the bottom at balancing weight, and the other end of ripping bar connects shackle；
The bottom of connecting plate is provided with suspension rod, and the other end of described suspension rod connects fork, the left part of described fork with unload
Button is connected.
The quantity of described microswitch is 2, and symmetrical is fixed on support swash plate, and stay bolt is from 2 fine motions
Gap between switch passes.
One end of described raceway connects with the bottom of balancing weight, and the other end of raceway is that the roller with microswitch is fitted mutually
The circular arc type structure answered.
Described gap is MENZI type structure.
One end of described fork is welded with wears pin plate, and described wearing is equipped with short pin shaft on pin plate, described short pin shaft
Middle part through the bottom of suspension rod.
The operation of the present invention is achieved in that the present invention in normal state, and fork is connected with ripping bar by shackle, pulls out
One end of fork is with short pin shaft for dumpling point, and fork is sagging under the effect of himself gravity, and the one end pulling ripping bar is sagging, due to sled
Balancing weight is prized it with the dumpling point of long pin shaft, the tip of ripping bar by bar, thus ripping bar is at balancing weight pressure and the work of the pulling force of fork
Being in poised state under with, ripping bar now is in level；During the electric block hoisting heavy of crane, when
When lifting hook pulley group rises to the position of fork, lifting hook pulley group will trigger fork, during suspension hook group rises, head on and pulls out
The right-hand member of fork rises, and car with short pin shaft for dumpling point, upwards moves in a circle, when the right-hand member of fork rises when, and fork pair
The pulling force of ripping bar will eliminate, thus the holding power of balancing weight is eliminated by ripping bar, balancing weight under the action of gravity of self along cunning
Rail slide downward, during balancing weight slide downward, the roller of microswitch will be oppressed in the upper end of the raceway on balancing weight,
Thus trigger microswitch, thus electric block system is run；When electric block is at lower section lifting thing, lifting hook pulley group declines
To the when of can not touching fork, fork resets, and balancing weight is levered up by ripping bar.
The invention has the beneficial effects as follows: the present invention by fork, ripping bar, balancing weight and microswitch each other
Coordinate, it is achieved the position that hoists the lifting hook pulley group of electric block carries out spacing, supporting, 2 microswitch be installed on swash plate,
Playing the effect of dual fail-safe, when preventing the microswitch from can not have little trick, another microswitch can play protection
Effect；The present invention has the advantage that dual fail-safe, safety are high.
