Abstract
The utility model belongs to a control device for reeling, unreeling and positioning of power lines of electrohydraulic grab buckets, electric clamps, electromagnetic disks and the like used under the lifting hook of a bridge or a portal crane, and particularly relates to a pilot cable positioning device for a cable drum of a crane. The pilot cable positioning device comprises a crane cable drum, wherein a support arranged at the lower part of a base of the cable drum is fixedly provided with upright and symmetrical positioning supports; belt support rolls are transversely and uniformly distributed on the symmetrical positioning supports; through a rolling shaft frame, the front part of the surface of the belt support roll at the upmost of each positioning support is provided with a rolling shaft parallel to the belt support roll and the spacing between the rolling shaft and the belt support roll is larger than the diameter of a cable; the cable passes from the spacing between the belt support roll and the rolling shaft; and the cable passing out is matched with the belt support roll at the lower part of the positioning support. The pilot cable positioning device can limit the swing amplitude of the cable along with a lifted article during the lifting process, reduce the phenomenon that the drum cable is pulled off or wound on the steel rope of the hook due to non-synchronization in use, improve the reliability of equipment lifting and prolong the service life of the cable.
Description
Technical field
The utility model belongs to the control setup, particularly hoisting crane cable drum pilot cable registration device of the folding and unfolding location of power leads such as bridge, the following electric hydraulic bucket that uses of transfer crane suspension hook, electric clamp, electromagnetic disc.
Background technology
The commercial production jackshaft, transfer crane is widely used, and many special occasions are more is using electric hydraulic bucket, electric clamp, electromagnetic disc etc.As raw scrap material zone a large amount of using electric hydraulic bucket, electromagnetic disc, the more use electric clamp in coiled material zone carries out material to be had bad luck, the sheet material Production Regional is used substantially is magnetic chuck.Owing in daily use, hang thing because swing is excessive, cause cable the random groove or the deflection of arranging to occur easily at cable drum, the asynchronous cable that causes that causes hoisting is broken.Simultaneously, cause the power supply circuit breaker to jump because cable causes cable failure earth fault or short trouble to occur following main hook as easy as rolling off a log and trolley frame friction in the ascending, descending process.Reliability as extraordinary lifting method electric power system is just particularly important.Above any situation falling accident that all will occur gliding occurs lifting goods and materials and wayside equipment are caused damage, cause whole production to be interrupted, What is more, and the personnel that cause injure, and consequence is very serious.Strengthen spot check every day in order to guarantee that reliability that lifting appliance is used and safety have only, each maintenance must be changed cable, and the also standby onboard cover cable of subregion magnetic disc suspending driving uses in order to emergent.
Summary of the invention
The purpose of this utility model is to provide a kind of hoisting crane cable drum pilot cable registration device, can limit in the process of hoisting cable with the amplitude of fluctuation of hanging thing, reduce drum cable and in use broken or twist in the phenomenon of suspension hook steel rope owing to nonsynchronous reason, the reliability of raising equipment handling, the service life of prolongation cable.
The purpose of this utility model is achieved in that a kind of hoisting crane cable drum pilot cable registration device, comprise the hoisting crane cable drum, on the support of cable drum base bottom setting, installing the locating support of upright symmetry, the horizontal uniform belt roller that is being provided with on the locating support of symmetry, the front portion that wherein is positioned at the belt roller roll surface of locating support the top is installed with the axis of rolling that parallels with this belt roller by the roller bearing frame, spacing between the axis of rolling and this belt roller is greater than the diameter of cable, cable passes from the spacing between this belt roller and the axis of rolling, passes cable and matches with the belt roller that is positioned at the locating support bottom.
The structure choice of the present utility model and the reasonable amplitude of oscillation of using framework alignment restrictions cable, utilize the rotation of belt roller to change into friction of rolling by cliding friction, can well reduce drum cable in use owing to the phenomenon of suspension hook steel rope is broken or twisted in to nonsynchronous reason, maintenance simultaneously conveniently more helps spot check and adjustment by cable.
This practical device is applicable to that hoisting crane is using cable drum and counterweight reel to give employed electric hydraulic bucket, electric clamp, and the guiding during the supply cable folding and unfolding of electromagnetic disc etc. has following technique effect:
One, cable was with the amplitude of fluctuation of the left, right, front and rear four direction that hangs thing during the new lead frame restriction of making of utilization hoisted and claims, reduce drum cable and in use broken or twist in the phenomenon of suspension hook steel rope owing to nonsynchronous reason, cable is changed into friction of rolling by cliding friction, improve the service life of cable, the man power and material of a large amount of saving plays the purpose of cost-cutting synergy.
Two, do not influence original design-calculated science: do not influence original trolley frame steelwork design, reduce as far as possible or do not use and be welded to connect, make cable drum wire positioning device and the cable drum base section of carrying out postwelding make bolt together, this device has certain restriction to space environment.
Three, improve the reliability of the handling of special equipment: the trouble point that the frequency is the highest is controlled, and the reliability of handling is greatly improved.
Therefore the utility model has realized that restriction hoists in the process cable with the amplitude of fluctuation of hanging thing, reduced drum cable in use, owing to the phenomenon of suspension hook steel rope is broken or twisted in to nonsynchronous reason, improved the reliability of equipment handling, prolonged the service life of cable.
