Abstract

A cantilever lifting limiting device belongs to the technical field of cantilever equipment, and is used for controlling the lifting position of a cantilever safely and reliably. The technical scheme is that the device is composed of a lifting hook over-winding limiting block, a limiting proximity switch, and a limiting separation plate, wherein the lifting hook over-winding limiting block is fixed at the lower part of a lifting hook lifting steel wire rope roller; the limiting proximity switch is mounted at the lower end of the lifting hook over-winding limiting block; the limiting separation plate is mounted at the upper end of a lifting hook; the limiting proximity switch is connected with a lifting relay. The device adopts the limiting proximity switch and the limiting separation plate to be used as lifting limit devices of the cantilever, so that the fieldwork environment can be adapted, the reliability of actions is greatly improved, the probability of the happening of an accident is greatly lowered, and the safety of an operator and the cantilever equipment is guaranteed; the device can conduct effective braking to avoid the phenomenon that a steel wire rope is stuck by a rope guider due to error actions so as to improve the service life the equipment; the device has the function that the production is s stabilized, and the material cost is saved.

Description

A kind of cantilever crane raising caging device
Technical field
The utility model relates to a kind of device that can control the cantilever crane hoisting position, belongs to the cantilever crane equipment technical field.
Background technology
Cantilever crane is the visual plant during iron and steel enterprise produces, and heavy-hammer limiting device is installed on cantilever crane, the safety of action when guaranteeing that cantilever crane rises, and the protection apparatus body is protected the operating personal personal safety simultaneously.In use procedure at the scene, operating personal finds that there is following problem in heavy-hammer limiting device:
1. because the site environment flue dust is large, cause the adhesion of mechanical connection point, make lifting position-limit error signal occur;
2. because in situ temperature is high, cause the plastic components in former weight hammer type inhibiting device aging, the signal wire (SW) obscission occurs, so just increased the probability of production development accident;
3. rope winding jib easily blocks steel rope, causes broken strand of steel cable, and safety misadventure easily occurs.
In view of above problem, be necessary existing cantilever crane heavy-hammer limiting device is improved.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of simple and reasonable, safe and reliable, simultaneously can be high temperature resistant and the cantilever crane raising caging device of anti-flue dust.
The technical scheme solved the problems of the technologies described above is:
A kind of cantilever crane raising caging device, it is comprised of suspension hook pulleying limiting stopper, spacing approach switch, spacing catch, suspension hook pulleying limiting stopper is fixed on the below of hook lifting wire rope drum, spacing approach switch is arranged on the lower end of suspension hook pulleying limiting stopper, spacing catch is arranged on the upper end of suspension hook, and spacing approach switch is connected with vertical relay.
Above-mentioned cantilever crane raising caging device, described spacing catch is rounded tabs, and the axis of spacing catch vertical direction and spacing approach switch central axis coincide, and the area of spacing catch is greater than the area of spacing approach switch.
The beneficial effects of the utility model are:
The utility model adopts spacing approach switch and the spacing catch raising caging device as cantilever crane, can adapt to the field activity environment, greatly improve the reliability of action, greatly reduced the probability had an accident, guaranteed the safety of operating personal and cantilever crane equipment; The utility model can be braked effectively, has avoided the phenomenon that causes steel rope to be blocked by rope winding jib because of misoperation, thereby improves equipment life, has reduced the more number of times of change steel rope, greatly reduces the labour intensity of maintenance work; The utility model has played the effect of steady production, has also saved material cost, and certain economic benefit is arranged.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: cylinder 1, motor 2, steel rope 3, suspension hook 4, suspension hook pulleying limiting stopper 5, spacing approach switch 6, spacing catch 7.
The specific embodiment
The utility model is comprised of suspension hook pulleying limiting stopper 5, spacing approach switch 6, spacing catch 7.
In figure, show, suspension hook pulleying limiting stopper 5 is fixed on the below of hook lifting wire rope drum 1, and spacing approach switch 6 is arranged on the lower end of suspension hook pulleying limiting stopper 5, and spacing catch 7 is arranged on the upper end of suspension hook 4.
In figure, show, spacing catch 7 is rounded tabs, and the axis of spacing catch 7 vertical direction and spacing approach switch 6 central axis coincide, and the area of spacing catch 7 is greater than the area of spacing approach switch 6.Spacing catch 7 can start spacing approach switch 6 while moving up.
In use, spacing approach switch 6 is connected with the lifting position-limit relay the utility model, and the contact of lifting position-limit relay is arranged in the electric power loop of contactless for hoisting.When suspension hook 4 rises, spacing catch 7 approaches the spacing approach switch 6 below suspension hook pulleying limiting stopper 5, when spacing catch 7 rises to 10 millimeters, spacing approach switch 6 interval (separately have a kind of 20 millimeters optional), spacing approach switch 6 conductings, the adhesive of lifting position-limit relay, disconnect contactless for hoisting, cylinder 1 stops operating, and suspension hook 4 stops rising.
