Abstract
The utility model provides a steel rope limiting device of an electric hoist crane, which consists of a contactor, a travel switch, a limiting plate, a feeler lever, a base and a buckle; the limiting plate is fixed below the balance pulley through a steel rope buckle, a contact rod hole is formed in the middle of the limiting plate, a contact rod at the lower end of a travel switch connected to a crane shell extends into the contact rod hole of the limiting plate, and the travel switch is connected with the contactor through a cable. When the crane steel rope deflects for a certain angle, the feeler lever contacts the inner side of the feeler lever hole of the limiting plate to trigger the travel switch, and the limit is disconnected through the limiting contactor, so that the limiting protection effect is realized. The utility model discloses simple structure, low in cost, the simple installation, the reliability is high, and the too big problem of incline appears in the crane steel cable of effective control, prevents because the too big crane that causes of incline damages, and extension crane life reduces maintenance work load and expense spending, avoids the emergence of equipment and personal safety accident.
Description
Technical field
The utility model belongs to wherein mechanical equipment field, relates in particular to a kind of steel cable inhibiting device for preventing that electric block crane angle of inclination is excessive.
Background technology
The electric block crane in use, inevitably exists because askew skewing dragged the phenomenon that deflection occurs, once and deflection is excessive, the lighter will cause crane to damage, and affect crane service life, increase maintenance load and expense to pay; Heavy there will be serious equipment and personal safety accident, its consequence is by hardly imaginable.
Summary of the invention
The utility model aims to provide a kind ofly can effectively control crane steel cable deflection, thereby avoids device damage, reduces service expenditure, stops the electric block crane steel cable inhibiting device of safety misadventure.
For reaching this purpose, the utility model has been taked following technical scheme:
A kind of electric block crane steel cable inhibiting device, is characterized in that, contactless switch, travel switch, positioning plate, feeler lever, base and buckle, consists of; The positioning plate two ends are fixed on crane equalizer pulley below by the steel cable buckle, positioning plate is middle with the feeler lever hole, both sides are with the steel cable hole, and the travel switch lower end feeler lever be connected on the crane shell by base stretches in positioning plate feeler lever hole, and travel switch is connected with contactless switch by cable.
Limit method of the present utility model and beneficial effect are:
Owing to having installed inhibiting device additional; after crane steel cable deflection certain angle; travel switch lower end feeler lever will touch inboard, positioning plate feeler lever hole; thereby triggering travel switch; travel switch is given spacing contactless switch by signal feedback, by electrical control, makes the limit disconnect, motor stalling; suspension hook can only fall and can not rise, thereby realizes the position limitation protection effect.
The utility model is simple in structure, cheap, simple installation, reliability is high, can effectively control the problem that the crane steel cable occurs that deflection is excessive, prevent that the crane that causes because deflection is excessive from damaging, extend crane service life, reduce maintenance load and expenses, avoid the generation of equipment and personal safety accident.
The accompanying drawing explanation
Fig. 1 is electric block crane steel cable limit device structure schematic diagram.
In figure: positioning plate 1, feeler lever hole 2, feeler lever 3, travel switch 4, base 5, cable 6, steel cable 7, crane equalizer pulley 8, contactless switch 9.
The specific embodiment
As seen from Figure 1, the utility model electric block crane steel cable inhibiting device mainly is comprised of positioning plate 1, feeler lever 3, travel switch 4, base 5, cable 6, steel cable 7, crane equalizer pulley 8, contactless switch 9.
After crane steel cable 7 deflection certain angles; travel switch 4 lower end feeler levers 3 will touch 2 inboards, feeler lever hole of positioning plate 1; thereby trigger travel switch 4; travel switch 4 is given spacing contactless switch 9 by signal feedback; by electrical control, make the limit disconnect; motor stalling, suspension hook can only fall and can not rise, thereby realizes the automatic spacing defencive function.
