Description
Technical field
It the utility model is related to a kind of punching of spacing above and below technical field of crane equipment, more particularly to electric block and preventing colliding with top
Bottom stopping means.
Background technology
Electric block is widely used in lifting weight, and electric block be able to will stop automatically after its suspension hook rises to upper height limit
Only, once otherwise operating personnel's carelessness can damage electric block；After suspension hook falls on lower limit, typically it can also be automatically stopped, it is no
Once the steel wire rope that then operating personnel's carelessness will also result on reel is chaotic, or even warp, processing is shut down.A kind of existing use
Screw mandrel, sliding block, the limiter of travel switch, height limit is carried out by screw mandrel band movable slider movement triggering travel switch, made
Used time, screw mandrel is connected by the spool shaft of gear and electric block, during electric hoist suspension hook upstream or downstream, sliding block exists
Position on screw mandrel just reflects the height of suspension hook, therefore, initial position of the adjustment sliding block on screw mandrel, so that it may adjust suspension hook
Position is automatically stopped, but the spacing height of this limiter adjustment will pull down screw mandrel, then initial position of the sliding block on screw mandrel is adjusted,
It is inconvenient, it is impossible to adapt to the different requirements of various types；Secondly as travel switch is typically used mechanically, by one section
After the use of time, due to the ablation of mechanical fatigue and travel switch internal electrical contact, travel switch understands failure, once stroke
Malfunctioning switch, electric block would not stop in precalculated position, cause to damage；In addition, electric block belongs to high-risk operations equipment,
Very high safety coefficient is needed, if stopping means contingency failure, suspension hook still may proceed to rising and cause the accident of rushing to summit up and down, or
Continuing traveling downwardly makes steel wire rope warp on reel, therefore, often requires that electric hoist stopper will not only have upper and lower limit function,
Also to possess preventing colliding with top function.
Utility model content
The utility model overcomes the deficiencies in the prior art, there is provided a kind of bound height of convenient adjustment suspension hook, energy

Slid axially in chute, position of the sliding block on screw mandrel reflects the height of suspension hook；When sliding block is moved to screw mandrel side
During upper limit correlation photoelectric sensor position, because the height of sliding block is higher to penetrating light than upper limit correlation photoelectric sensor,
Sliding block just blocked upper limit correlation photoelectric sensor to penetrating light, upper limit correlation photoelectric sensor is just to electric block control
Device processed sends electric signal, and electric block just shuts down；When electric hoist suspension hook declines, screw mandrel band movable slider is anti-in chute
To sliding axially, when sliding block block lower limit correlation photoelectric sensor to penetrating light when, lower limit correlation photoelectric sensor
Electric signal just is sent to electric block controller, electric block just shuts down；When need to adjust the upper limit or low limit level, pine is only needed
Open the screw of fixed upper limit correlation photoelectric sensor or lower limit correlation photoelectric sensor, mobile upper limit correlation photoelectric sensing
The position of device or lower limit correlation photoelectric sensor on screw mounting groove, then by upper limit correlation photoelectric sensor or lower limit pair
The formula photoelectric sensor of penetrating is locked on screw mounting groove, and operation is very convenient；Just in case upper limit correlation photoelectric sensor or under
Correlation photoelectric sensor failure is limited, suspension hook continues to rise or fall, and sliding block also continues to move axially outward, when sliding block is moved to
When preventing colliding with top correlation photoelectric sensor or erosion control bottom correlation photoelectric sensor position, sliding block has blocked preventing colliding with top correlation light
Electric transducer or erosion control bottom correlation photoelectric sensor to penetrating light, preventing colliding with top correlation photoelectric sensor or erosion control bottom are to penetrating
Formula photoelectric sensor sends electric signal to electric block controller, and controller control electric block stops operating and braked, prevents
Bottom is rushed to summit or rushed to suspension hook.
Further, described screw mandrel one end is connected by bearing with base rotation.For making the rotation of screw mandrel more smooth.
The beneficial effects of the utility model are：Using upper limit correlation photoelectric sensor and lower limit correlation photoelectric sensor
Switch, can be avoided because mechanical fatigue and travel switch internal electrical contact ablation cause row instead of traditional mechanical stroke
Journey malfunctioning switch, make stopping means operation relatively reliable；Chute is set on base, guide pad is set on sliding block, makes sliding block
It can only axially move；Two screw mounting grooves are set to be used to fix each correlation photoelectric sensing on the base of screw mandrel side
Device, by adjusting the installation site of upper limit correlation photoelectric sensor and lower limit correlation photoelectric sensor on screw mounting groove
Just adjustable upper and lower bound height, it is very convenient；Preventing colliding with top correlation photoelectric sensor and erosion control bottom correlation photoelectricity are set
Sensor can be in the case of upper limit correlation photoelectric sensor or lower limit correlation photoelectric sensor contingency failure to electronic
Cucurbit plays further protection, prevents suspension hook from rushing to summit or rushing bottom and causing the accident.
