Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.It should be appreciated that the specific embodiments described herein are only used to explain that this is practical
It is novel, it is not used to limit the utility model.
As shown in Figs 1-4, the utility model embodiment provides a kind of turning pulley gear of detectable slack rope, including cunning
Wheel seat 1, pulley moving tooth free bearing 2, detection switch 3, pulley 4 and wirerope 5,
The pulley moving tooth free bearing 2 is mounted on the pulley base 1, and the pulley 4 is mounted on the pulley moving tooth free bearing 2
On, the pulley 4 and the pulley moving tooth free bearing 2 can be swung in a certain range, and the wirerope 5 passes through the pulley
4, and the pulley moving tooth free bearing 2 blocks the wirerope 5 from the outside of the pulley 4,
The detection switch 3 is mounted on the pulley base 1, and when the pulley 4 and the pulley moving tooth free bearing 2 are downward
When swing, the detection switch 3 can trigger.
The turning pulley gear of the detectable slack rope of above structure, its working principle is that:
In the state that wirerope does not loosen, the resultant force in 45 degree of directions is formed into rope power and rope stretching power, pulley is tensed,
When wirerope relaxes, since pulley and pulley moving tooth free bearing can be swung in a certain range, then pulley can be in weight
To lower swing under power effect, and then detection trigger switchs, and would know that relaxation occurs in the wirerope by detection switch.To real
Now to the detection of the rapid sensitive of steel wire rope looseness phenomenon, and the one-to-one detection to steel wire rope looseness phenomenon is realized, so,
It is more flexible reliable using the turning pulley gear of detectable slack rope provided in this embodiment, it can relax in wirerope
When take timely measure, eliminate safe hidden trouble and fluctuation of service factor.
In the present embodiment, fixed main shaft hole 1.2, swingable pulley spindle waist hole 1.3 and gear rope are provided on the pulley base 1
Axis swings hole 1.1, and the pulley moving tooth free bearing 2 is right respectively by fixed main shaft 2.2, swingable pulley spindle 2.3 and gear reel for rope 2.1
The fixed main shaft hole 1.2, swingable pulley spindle waist hole 1.3 and gear reel for rope should be mounted on to swing in hole 1.1 and be connected to the cunning
On wheel seat 1, the pulley 4 is mounted in the swingable pulley spindle waist hole 1.3 by the swingable pulley spindle 2.3 and is connected to
On the pulley moving tooth free bearing 2, the swingable pulley spindle 2.3 and gear reel for rope 2.1 can be respectively in the swingable pulley spindle waists
Hole 1.3 and gear reel for rope swing in hole 1.1 and swing.
Using the above structure, it can be achieved that a certain range of swing and pulley of the pulley on pulley moving tooth free bearing are dialled
A certain range of swing of the tooth free bearing on pulley base, works as looseness of steel wire ropes, and pulley under the effect of gravity can be around fixed main shaft
When rotating down, downward rotation can occur therewith for pulley moving tooth free bearing, so that detection trigger switchs.
Meanwhile in above structure, blocking of the pulley moving tooth free bearing to the wirerope for passing through pulley can be realized by keeping off reel for rope
Effect, avoids wirerope from splitting away off from pulley.
In the present embodiment, the pulley moving tooth free bearing 2, detection switch 3, pulley 4 may be configured as it is multiple, and with the steel
The quantity of cord 5 is corresponding consistent.
Using the above structure, the hoist engine for different rope stretching numbers can be optionally combined.
By using above-mentioned technical proposal disclosed by the utility model, following beneficial effect: the utility model has been obtained
The turning pulley gear for the detectable slack rope that embodiment provides, by installing detection switch on pulley base, when across pulley
When wirerope relaxes, pulley can be in swingable range to lower swing, so that detection trigger switchs, to realize to steel wire
The detection of the rapid sensitive for relaxation of restricting, and the one-to-one detection to steel wire rope looseness phenomenon is realized, so, using this reality
The turning pulley gear of the detectable slack rope of example offer is provided, it is more flexible reliable, it can be adopted in time when wirerope relaxes
Measure is taken, is eliminated safe hidden trouble and fluctuation of service factor.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching should also regard the protection scope of the utility model.
