Abstract
The utility model discloses a gantry crane cart operational obstacle detecting device, which comprises an ultrasonic sensor 1, a contactor KM, an indication lamp HL and a buzzer FM. A power input end of the ultrasonic sensor 1 is connected with a power source, a normally closed contact K1 of the ultrasonic sensor 1 is connected in series with a coil of the contactor KM, two ends of the series circuit are connected with the power source, a normally open contact of the contactor KM is connected in series with the indication lamp HL, two ends of the series circuit are connected with the power source, and the buzzer FM is connected in parallel with the indication lamp HL. When the ultrasonic sensor detects obstacles, such as large obstacles on a track and occasionally passing construction workers, within a sensing area, and the device automatically gives out acoustic-optic warning and audio prompt to remind the workers to clear the obstacles on the track or to remind the passing construction workers to leave the track, thereby eliminating safety hidden hazards during operation of a crane.
Description
Technical field
The utility model relates to a kind of obstacle detector, relates in particular to a kind of transfer crane cart interruption of service quality testing and surveys device, belongs to the weight-lifting equipment technical field.
Background technology
The safety device of large-tonnage transfer crane traveling mechanism of the larger traveller mainly contains infrared ray remote control and clear rail plate at present, its middle infrared (Mid-IR) remote control uses in pairs, one end is fixed on cart car bumper place, one end is fixed on the little equalizing bar of hoisting crane, its effect is to carry out early warning when crane runs to cart orbit end, when preventing that hoisting crane from running to rail end and the collision of cart car bumper cause rollover or derailment accident; Clear rail plate is generally apart from 10 millimeters of rail level height, be used for removing the obstacle on the operational process rail level, as little iron plate, little foreign material etc., but clear rail plate for the large-scale obstacle on the rail level and once in a while the workmen of process then can't carry out early warning and removing, the therefore bigger safety misadventure hidden danger of existence.
The utility model content
The purpose of this utility model is to provide a kind of transfer crane cart interruption of service quality testing to survey device, as detects and have obstacle then can carry out automatic sound-light alarm and voice suggestion in the induction region, eliminates safety misadventure hidden danger.
The purpose of this utility model is achieved by the following technical programs:
A kind of transfer crane cart interruption of service quality testing is surveyed device, comprises ultrasonic transduter 1, contactless switch KM, indicator lamp HL, buzzer phone FM.The power input of described ultrasonic transduter 1 links to each other with power supply, the normally closed contact K1 of ultrasonic transduter 1 connects with the coil of contactless switch KM, these circuit series two ends link to each other with power supply, the open contact of described contactless switch KM is connected with indicator lamp HL, the two ends of this circuit series are connected in power supply, and described buzzer phone FM is in parallel with indicator lamp HL.
The purpose of this utility model can also further realize by following technical measures:
A kind of transfer crane cart interruption of service quality testing is surveyed device, and wherein ultrasonic transduter 1 is installed on the bogie frame.
Compared with prior art, the beneficial effects of the utility model are: ultrasonic transduter detects obstacle in the induction region (comprising the large-scale obstacle and the workmen of process once in a while on the rail level), then carry out automatic sound-light alarm and voice suggestion, remind the staff to remove the obstacle of rail level, or remind the workmen of process to leave rail level, eliminate the potential safety hazard of hoisting crane operation.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
Fig. 2 is ultrasonic transduter installation site figure.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model comprises ultrasonic transduter 1, contactless switch KM, indicator lamp HL, buzzer phone FM.The power input of ultrasonic transduter 1 links to each other with power supply, the normally closed contact K1 of ultrasonic transduter 1 connects with the coil of contactless switch KM, these circuit series two ends link to each other with power supply, the open contact of described contactless switch KM is connected with indicator lamp HL, the two ends of this circuit series are connected in power supply, and described buzzer phone FM is in parallel with indicator lamp HL.
As shown in Figure 2, the ultrasonic transduter 1 of present embodiment is arranged on driven bogie 4 front ends, is positioned at energy disperser 5 upsides.The utility model transfer crane traveling mechanism of the larger traveller obstacle detector is on the basis of original infrared ray remote control and clear rail plate, on bogie frame, increase by a cover ultrasonic transduter 1, it effectively detects distance is 0.2～8 meter, and can adjust induction region according to actual needs, when work, as detect have in the induction region obstacle then the coil of contactless switch KM get, the open contact closure of contactless switch KM, indicator lamp HL and buzzer phone FM work, carry out sound and light alarm, this moment, the staff in time removed obstacle, improved the safety performance of hoisting crane widely, failure-free prevention and control have been accomplished by the accident potential that causes that has some setbacks owing to the cart operation.Ultrasonic transduter is selected Schneider " Osisonic " ultrasonic transduter for use; degree of protection IP65 meets IEC60529 and IEC60947-5-2, working temperature range :-20 ℃～60 ℃; have short-circuit protection function, switching frequency and transmitting frequency can satisfy the working condition requirement of hoisting crane fully.This obstacle detector can satisfy the requirement of GB/T3811-2008 " hoist design specification " fully, makes large-tonnage safety of gantry crane coefficient improve greatly by less input.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
