Description
Technical field
The utility model relates to hoist equipment technical fields, more specifically, it relates to a kind of ring-chain hoist lifting
The anti-roll control devices of equipment.
Background technique
Endless chain hoist is frequently used on voluntarily transport trolley, as a kind of common lifting equipment using 2 or 2
The more than platform form of (harbour group hangs) carries out lifting operation, the chain that the chain of endless chain hoist is arranged by square crossing to article
Section composition.When hoist crane has 2 or 2 or more, it is possible to which (such as suspension hook loading capacity in both sides is poor under the influence of certain factors
Different larger, the intrinsic mechanical property difference of two cucurbits is inconsistent to the start stop signal response time, and mechanical wear leads to skidding etc.) meeting
There is nonsynchronous situation between each cucurbit.At this point, the faster cucurbit one end of the speed of service is just if cucurbit is in ascent stage
Can it is higher, the other end is lower, and if cucurbit is in the decline stage, the faster cucurbit one end of the speed of service will be lower, the other end compared with
Height, moreover, this difference of height can increase with the running time increases, so as to cause institute's hanging object product knockdown, releaser
Product disequilibrium and the safety accident toppled.
The existing nonsynchronous scheme of ring-chain hoist operation for preventing 2 or 2 or more has:
Scheme 1: being arranged cross bar on suspender, and cross bar both ends respectively install microswitch one, 1 steel ball is filled inside cross bar, when
When suspender runs asynchronous run-off the straight because of 2 cucurbits, cross bar tilts simultaneously, and steel ball rolls to low one end triggering microswitch,
Issuing signal stops ring-chain hoist operation.
Scheme 2: installing rotary encoder on the motor shaft of each ring-chain hoist, and encoder is synchronous with motor shaft rotation, when
When there is the slow situation of another cucurbit of a cucurbit fast speed, what is be connected with rotary encoder output signal is risen
Weight trolley main control PLC judges that this handling produces asynchrony phenomenon by parameter preset.And it can be further (according to PLC program
The control complexity write) it is modified according to the shift value that rotary encoder is sent to asynchronous.
Respectively there is disadvantage in prior art:
The shortcomings that scheme 1 is the switching signal that steel ball triggering microswitch can only issue " having generated inclination ", trolley
Main control PLC can only make the reaction for stopping all cucurbit operations to switching signal, can only prevent inclination phenomenon from further deteriorating.And
Which side it cannot judge higher (or lower) and correct automatically to roll.And steel ball is sometimes because hanging object swing leads to steel ball rolling
Cause false triggering.Meanwhile being fixed between the cross bar on suspender and trolley main control PLC usually has longer connecting line (long
Degree is at least the maximum adjustable height of cucurbit), and this connecting line moves up and down with suspender, easily causes connecting line disconnected, shielding failure.
The shortcomings that scheme 2 is that rotary encoder price is higher, the mating various interface boards connecting with trolley main control PLC
Value is even more than ring-chain hoist itself after card, can be only applied to some pairs of extra high occasions of synchronous hoisting requirement, other
Without this application as unification.
Utility model content

Device includes ring set, the inductive switch on the ring set for being set in the hollow structure of the chain periphery, the induction
The signal output end of switch is connect with the signal input part of trolley main control PLC.
As a further improvement, setting the sense described in two there are two the inductive switch being arranged symmetrically on the ring set
Inductive switch is corresponding with the radial position of the chain link.
Further, the chain guide is equipped with the pilot hole of cross structure, the pilot hole and described
Chain is adapted.
Further, the hole size of the ring set is greater than the full-size of the chain periphery.
Further, the inductive switch is induction close to switch.
It further, is to be threadedly coupled between the inductive switch and the ring set.
Further, the side being located on the inductive switch in the ring set is equipped with protective case.
Beneficial effect
The utility model compared with prior art, has the advantage that are as follows:
1, the chain link moved in ring set by inductive switch real-time detection chain, inductive switch transmitting detection signal are given
Weight trolley main control PLC, trolley main control PLC can control each cucurbit according to mobile chain number and suspend or start to realize together
Step operation can effectively correct inclination, and job stability is high, manufacturing cost is low；
2, two inductive switches being arranged symmetrically are set, chain link can be effectively detected, prevent from occurring because of chain swinging partially
Difference；
3, convenient that the position of inductive switch is adjusted to be threadedly coupled between inductive switch and ring set；
4, protective case is arranged in inductive switch periphery, inductive switch can be prevented by chain swinging with effective protection inductive switch
It breaks；
5, the mobile posture of chain can be effectively ensured in chain guide, prevent chain from rotating and generating detection error.
