Abstract
The utility model discloses a double-layered windlass with automatic cut-off devices, of which the structure mainly comprises a head pulley, an electric motor, a warping drum and a wire cable. The critical improvement lies in that the two automatic cut-off devices are respectively arranged below the double-layered wire cable, each automatic cut-off device mainly comprises a cross rod, a spring and a displacement sensor, and the displacement sensor is connected with a PLC input module which controls the electric motor. Once looseness or jamming of the wire cable occurs during the operation of the double-layered windlass, the electric motor can be disconnected via the automatic cut-off devices to stop the operation, so as to prevent such serious accidents as fractured wire cable, casualties caused by downfallen hung heavy objects and equipment damage. Therefore, safety production is ensured.
Description
Technical field
The utility model belongs to the electrical category technology, relates to a kind of winch that can cut off the power supply automatically, prevents the double-deck winch of the band of contingency from breaker device when particularly making vertical transport and hoisting operation.
Background technology
At present, known electric winch all is made up of head sheave, electrical motor, barrel, steel rope and mounting, and manufacturer only considers the material selection, and working accuracy and package technique, the safety in production problem of winch are all left the user for and solved.
The steel rope of double-deck winch is after twining on the barrel, two terminations are respectively along two parallel hanging down of draw-in groove of head sheave, usually the end that will guide head sheave through the barrel top into becomes the upper strata steel rope, and an end of guiding head sheave through the barrel below into is called lower floor's steel rope.When the motor drives barrel rotated, the upper strata steel rope was with the weight then lower floor's steel rope Panasonic of slinging; The rotation direction of barrel is conversely the time, and lower floor's steel rope is then sling weight, upper strata steel rope Panasonic.In the process of dress lift heavy thing; often can occur also adorning that the weight that hangs is squatted at the end (promptly arriving ground) or midway during the steel rope jam; absent minded or sight line such as is kept off at reason owing to operating personal; fail in time to shut down; remain in operation; cause an end of the weight of slinging to hit the disconnected rope in top; other end steel rope is lax to be run out of outside the reel; and twine on other device that is stuck in outside the reel; when starting once more,, can directly cause wire cable rupture like this because steel rope is stuck; the lifted weight thing falls, and causes casualties, device damage.Existing double-deck winch with generally all be arranged on winch lower floor steel rope from breaker device, cause the upper strata winch to transfer the accident that wire line shoe stopband in the process of weight comes and can't avoid.
The utility model content
The technical problems to be solved in the utility model is by a kind of double-deck winch that has from breaker device is provided, to have prevented the accident in the double-deck elevator machine operation process more all sidedly, especially the accident that produces because of upper strata steel rope operation fault.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the below of upper strata steel rope and lower floor's steel rope is provided with two respectively from breaker device, mainly comprise cross bar, spring and displacement pickup from breaker device, displacement pickup links to each other with the PLC load module at control motor.
Preferably, the cross bar two ends are separately fixed on two supports, and of cross bar is connected with the support hinge, and the other end is arranged on the support by spring suspension and sensing chip is set on the termination, displacement pickup be normal make war near switch.
Adopt the beneficial effect that technique scheme produced to be: by below the double-layer wire rope, being provided with two respectively from breaker device, no matter the upper strata steel rope still is lower floor's steel rope, and the lax or jam phenomenon of steel rope takes place in operation process, can be by cutting off electrical motor from breaker device, shut down, avoid wire cable rupture, the lifted weight thing fall cause casualties, the generation of serious accident such as device damage, safety in production is guaranteed.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is a scheme of installation of the present utility model;
Fig. 2 is a side schematic view of the present utility model.
The specific embodiment
For making above-mentioned purpose of the present utility model, feature and advantage can become apparent more, below in conjunction with the drawings and specific embodiments among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1 and Fig. 2, a kind of band is from the double-deck winch of breaker device, mainly comprise head sheave 1, electrical motor 2, barrel 3 and steel rope 4 in its structure, the improvement of its key is that the below of upper strata steel rope 4-1 and the steel rope 4-2 of lower floor is provided with two respectively from breaker device 5, mainly comprise cross bar 6, spring 7 and displacement pickup 8 from breaker device 5, displacement pickup 8 links to each other with the PLC load module at control motor, wherein displacement pickup be normal make war near switch.
Cross bar 6 two ends are fixed on two supports in breaker device, one of cross bar is connected with the support hinge, the other end hangs by spring 7 and is arranged on the support, and sensing chip 9 is set on the termination, displacement pickup 8 is arranged on the support of sensing chip one end, is 5-8mm near the distance between switch and the sensing chip.
When double-deck winch normal operation, two-layer up and down steel rope all is in the state of tightening.Remain near the distance between switch and the sensing chip in the active distance 5-8mm scope of induction, near switch conduction make normal make war near switch closure, the PLC program is normally moved, electrical motor normally moves.In case steel rope jam phenomenon takes place in steel rope in operation process, steel rope is because of the lax cross bar of pushing down, by gravity, cross bar is hung down to cause near the distance between switch and the sensing chip by a spring mounted end and has exceeded distance of reaction 5-8mm, then normal switch disconnection battle of inductive switch, the program outage in the PLC module, the output point of control motor operation disconnects, and electrical motor is out of service.
By below the double-layer wire rope, being provided with two respectively from breaker device, no matter the upper strata steel rope still is lower floor's steel rope, and the lax or jam phenomenon of steel rope takes place in operation process, can be by cutting off electrical motor from breaker device, shut down, avoid wire cable rupture, the lifted weight thing fall cause casualties, the generation of serious accident such as device damage, safety in production is guaranteed.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
