Description
Technical field
It the utility model is related to technical field of crane equipment, more particularly to a kind of electric block height limitator.
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, it is existing it is a kind of using screw mandrel, sliding block, travel switch limiter,
Height limit is carried out by screw mandrel band movable slider movement triggering travel switch, in use, screw mandrel is passed through into gear and electronic calabash
The spool shaft drive connection of reed, during electric hoist suspension hook upstream or downstream, position of the sliding block on screw mandrel just reflects suspension hook
Highly, therefore, initial position of the sliding block on screw mandrel is adjusted, so that it may adjust the position that is automatically stopped of suspension hook, but this limiter
Screw mandrel will be pulled down by adjusting spacing height, then adjust initial position of the sliding block on screw mandrel, be inconvenient, it is impossible to adapt to various types
Different requirements.
Utility model content
The utility model overcomes the deficiencies in the prior art, there is provided a kind of convenience adjusts the electronic of the limit level of suspension hook
Cucurbit limiter.
The utility model is achieved through the following technical solutions：
A kind of electric block height limitator, including base, with electric gourd drum axle drive connection gear, the bottom of through
The sliding block that seat both ends are rotatablely connected with its both ends and are connected with the screw mandrel of gear axis connection and wire rod thread；Below the screw mandrel
Base be provided with and be used for the chute that is play the guiding role to sliding block；The sliding block is provided with guide pad, and the guide pad is stuck in chute
It is interior, sliding block is slided from being rotated in chute in chute；The base of the screw mandrel side is provided with two
The screw mounting groove parallel with screw mandrel；The side of the sliding block is switched provided with one stroke, and the trip switch is fixed by screws in
On screw mounting groove.
In use, the controller of travel switch and electric block is electrically connected, when electric hoist suspension hook rises, spool shaft
Pinion rotation is driven, gear drives screw mandrel to rotate, and screw mandrel band movable slider slides axially in chute, position of the sliding block on screw mandrel
Put the height for reflecting suspension hook；When sliding block touches travel switch, travel switch sends electric signal to electric block controller, control
Device control electric block processed stops operating and braked；When need to adjust limit level, the screw of fixed journey system switch need to be only unclamped, is moved
Dynamic position of the travel switch on screw mounting groove, then travel switch is locked on screw mounting groove, operation is very convenient.
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：Chute is set on base, guide pad is set on sliding block, makes sliding block can only
Axially move；Two screw mounting grooves are set to be switched for fixed journey system on the base of screw mandrel side, by adjusting stroke
Switch the installation site on screw mounting groove and just can adjust limit level, it is very convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
As depicted in figs. 1 and 2, embodiment of the present utility model, a kind of electric block height limitator, including base 1, with
The gear 2 of electric gourd drum axle drive connection, it is rotatablely connected with its both ends through the both ends of base 1 and is fixedly connected with gear shaft
Screw mandrel 3 and screw mandrel 3 be threadedly coupled sliding block 4；The base 1 of the lower section of screw mandrel 3, which is provided with, to be used to play sliding block 4 in guiding work
Chute 5；The sliding block 4 is provided with guide pad 6, and the guide pad 6 is stuck in chute 5, prevents sliding block 4 from being done in chute 5
Rotary motion, it can only be slided in chute 5；The base 1 of the side of screw mandrel 3 is provided with two screw peaces parallel with screw mandrel 3
Tankage 7；The side of the sliding block 4 is provided with one stroke switch 8, and the trip switch 8 is fixed on screw mounting groove 7 by screw 9.
In use, the controller of travel switch 8 and electric block is electrically connected, when electric hoist suspension hook rises, reel
Shaft driven gear 2 rotates, and gear 2 drives screw mandrel 3 to rotate, and screw mandrel 3 slides axially with movable slider 4 in chute 5, and sliding block 4 exists
Position on screw mandrel 3 reflects the height of suspension hook；When sliding block 4 touches travel switch 8, travel switch 8 controls to electric block
Device sends electric signal, and controller control electric block stops operating and braked；When need to adjust limit level, only fixed row need to be unclamped
Cheng Kaiguan 8 screw 9, shift motion switchs 8 position on screw mounting groove 7, then travel switch 8 is locked at into screw installation
On groove 7, operation is very convenient.
In the present embodiment, described one end of screw mandrel 3 is rotatablely connected by bearing 10 and base 1.For making the rotation of screw mandrel 3 more
Add smooth.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work, should all cover within the scope of protection of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
