Abstract
The utility model discloses a novel list drum hoisting machine slack rope protection of restricting device. Include: hoist engine cylinder, wire rope, play rope mouth, infrared protection device, support. Characterized by utilizes infrared signal's highly sensitive nature, and the delay relay in the control box prevents that mistake nature improves the sensitivity and the reliability of slack rope protection. Current slack rope protection in the practice is used, exists multiple applied drawback and potential safety hazard, if: sensitivity is low, and the reliability is poor.
Description
Technical field
The utility model belongs to technical field of automation., particularly relate to a kind of device of novel single rope winding hoist rope creep protection.
Background technology
, in practical application, there is multiple application drawback and potential safety hazard in existing rope creep protection, as: sensitivity is low, poor reliability, is badly in need of improving.This fender guard makes up its shortcoming, simultaneously with steel rope no touch, without wearing and tearing.
Summary of the invention
Principle of work: infrared fender guard is made up of illuminator and light-receiving device, is installed on rope outlet both sides.When not having obstacle between the infrared illuminator on same straight line and light-receiving device, the modulation signal (optical signal) that infrared transmitting tube sends can arrive infrared receiving tube smoothly.After infrared receiving tube accepts modulation signal, corresponding internal circuit output low level; When having obstacle, respective inner circuit exports high level.When hoisting cable generation slack rope accident, steel rope falls into protection zone, and fender guard sends alerting signal.
Performance characteristics: 1, antijamming capability is strong, adopts infrared modulation light source, does not substantially irradiate interference by sunlight, indoor light; 2, be quick on the draw: the reaction time is not more than 50 μ s; 3, there is misoperation recognition function, controlled by time relay, avoid misoperation; 4, a little repair, failure rate is low; 5, utilize 24V direct supply, make whole device be in below safety voltage, ensure operation service personnel safety.
Accompanying drawing explanation
Accompanying drawing 1 is electrical schematic diagram of the present utility model.
Accompanying drawing 2 is device schematic diagram, 1: winch cylinder 2: steel rope 3: rope outlet 4: infrared fender guard 5: support.
Detailed description of the invention
1, before running, first DC power control K switch closed, HG lamp is bright, and expression system obtains electric.
2, before motor-car, change-over swith ZK is dropped into co-bit, HY lamp is bright simultaneously, rope creep protection system control loop is obtained electric; Motor-car is complete, cut-off breaker K.When falling into 4 infrared fender guards in 2 steel rope operational processs, time relay sj obtains electric, and after the time delay of setting, contact SJ action, relay ZJ obtains electric, and contact ZJ1, ZJ2 are closed, and now buzzer phone FW information ring, warning light HR is bright.
3, in accident settlement process, ZK can be disconnected, remove information ring.After waiting for that settlement of accident is complete, system place in operation again again.
4, infrared fender guard action delay time, the actual delay time that actuating signal sends, namely time relay delay time, is adjusted to 0.8s.Spurious signal is sent when avoiding steel rope amplitude of fluctuation large.
Claims (4)
1. a novel single rope winding hoist rope-loosing protection device, comprises winch cylinder, steel rope, rope outlet, infrared fender guard, support, it is characterized in that the steel rope be wrapped on winch cylinder is extended out by rope outlet; Support is fixed on the lower edge away from winch cylinder side of rope outlet; Infrared fender guard is fixed on support, and the top of infrared fender guard should be placed in the below of rope outlet place steel rope simultaneously; Infrared fender guard gathers Signal transmissions when steel rope falls into protection domain in control box.
2. rope-loosing protection device according to claim 1, is characterized in that, described signal adopts infrared signal.
3. rope-loosing protection device according to claim 1, is characterized in that, described control box includes free relay and prevents slack rope erroneous judgement.
4. rope-loosing protection device according to claim 1, is characterized in that, the action command that described control box sends acts on Warning light in caution bell.
