Abstract

The utility model relates to a collision avoidance alarm for producing heavy bridge cranes. The utility model is composed of a bridge crane body (1), a buffer (5), a wheel (9) and a photoelectric control circuit. The utility model is mainly characterized in that a photoelectric head which is fixed on the buffer (5) by a clamping plate (15) and a screw (16) carries out photoelectric conversion; the distance of the photoelectric head is adjusted by an optical source; an alarm device sends out alarm before the inertia stroke of the crane is run; thus, the crane reduces speed, powers off or stops in the chronic stroke, which avoids the collision of the two cranes. The utility model is safe and reliable.

Description

Collision avoidance alarm for a bridge crane

A kind ofly be used to produce severe duty crane in bridge type proximity warner.

Existing proximity-warning device is that Baosteel is controlled car to car impact with Principles of Laser, about about 1.2 ten thousand yuan of every price, and most of steel mills all there are not employing.Because crane in bridge type turns round on two specific rectilinear orbits, operating rate is more frequent, locomotive under the same factory building operation is several continuous workings often, distance between car and the car is very near again, for 275 tons of pig moulding machines, hoisting crane adopts DC control, and the speed ratio of the locomotive operation on the same track is also different, the fifties " Soviet Union's formula " locomotive, 54 meters of per minute operations, head reach 4-6 rice, 62 meters of sixties Germany's locomotive per minute operations of making, head reach 6-9 rice, drg all is to adopt coil is connected on ZWZ500 type electric brake in the power circuit, moves with the work of power circuit, when the locomotive full speed running, it is unexpected that the adjacent car of finding arranged, think left alone without help car at once, because head reach also can't be avoided car to car impact, the crane in bridge type of steelworks often hangs and unloads liquid molten steel, if the collision accident takes place, the molten steel splash causes casualties, device damage, country and individual bring very big loss.

In order to overcome above-mentioned shortcoming, the utility model proposes one more simple, safety, reliably, can alleviate driver's burden, improve the locomotive shunting rate, the compared with prior art component invention of photoelectric control circuit that cost is lower and overhead traveling crane locomotive, carry out special opto-electronic conversion by photometer head, photometer head (7) is fixed on above the energy disperser (5) with clamping plate (15) and screw (16), adjust the focus of photometer head by light source, it is controlled apart from distance, proximity warner sent warning before the locomotive driving head reach, remind the driver to travel at a slow speed, or outage, or the stop running, prevent car to car impact.

Embodiment:

This device has adopted three segment distance may command programs, and F/s is for reporting to the police regulator potentiometer W ₁, first program that makes crane is 10 meters distances, when two cars siren horn at a distance of 10 meters the time sends alerting signal, remind the driver note with adjacent spacing to 10 meters, this moment, stop turned round at once as driver's full speed running, its inertia can be gone out 6 meters, and 4 meters safety distance is still arranged.

The second distance programming control, after locomotive is crossed the F/s warning, when still needing to turn round, that is to say because the restriction of operating environment, need operation in several meters, at this moment locomotive just can not turn round at full speed, and we establish this program made locomotive slow down before head reach apart from being 8 meters, if locomotive slows down as yet within head reach, so because inertia will cause collision, so, locomotive is run slowly, could guarantee safety.

The 3rd program distance is 1 meter, when locomotive travels at a slow speed, still might in order to guarantee not collide, must stop in 1 meter distance near adjacent car, and the 3rd program is cut off the power supply power circuit automatically, quits work.Locomotive is very little at the stroke of low-speed running.

Principle of work

Circuit is seen figure, BG ₁Be connected into emitter-follower, its upper offset circuit is by photoconductive cell and R ₁Form, strong when the light irradiation when near of two cars, the internal resistance of photoconductive cell diminishes, and two cars are when far away, and a little less than the light irradiation, the interior resistive of photoconductive cell is big, adds variable resistance on below-center offset, so just can change BG ₁Base current, to reach the purpose of command range, work as BG ₁There is base current to make its conducting, BG ₁The electric current of emitter output directly has been added to BG ₂Base stage, so BG ₂Conducting enters saturated very soon, I _C2Starting relay J adhesive.

Owing to consider that unnecessary siren horn does not ring the generation noise for a long time when driving, and all there is the possibility of locomotive shunting the both sides of locomotive, photometer head must all be housed in both sides, therefore need a change-over circuit, control J respectively with the auxiliary contact of often opening of direction contactless switch ZC, FC on the locomotive cart control panel ₄, J ₅Adhesive, when locomotive when positive dirction turns round, positive dirction contactless switch ZC adhesive, it often opens auxiliary contact conducting, J ₅Adhesive, J _5-1J _5-2J _5-3J _5-4J _5-5J _5-6Normal conducting battle, will in the photometer head incircuit of positive dirction running, make photoelectric switching circuit work.

During the reversing sense running, FC connects, J ₄Adhesive, its principle is identical.

When locomotive is not worked, ZC, not adhesive of FC, photometer head in the incircuit, do not work by acoustics circuit.

First program: audible alarm, when two cars to (adjusting W during first distance to a declared goal ₁Determine distance) J ₁Adhesive, contact J _1-1Conducting, acoustics circuit work, J _1-2Conducting, indicator lamp is bright.Contact J _1-1Conducting triggers audio ic and sends music, BG ₁₀Effect is to increase one-level to amplify and impedance match resistance R ₆Be current-limiting resistance, R ₅Be dropping resistor, R ₄Be to trigger resistance.

Second program: run slowly, when two cars have arrived the second distance of appointment, (adjust W ₂Determine distance) J ₂Adhesive, J _2-1Normally closed contact disconnects, and makes the controller K in the locomotive running gear functional arrangement ₇Line disconnects, and contactless switch FJC can not adhesive, makes the later accelerating contactor all can not adhesive.Reach the low-speed running purpose.

The 3rd program: automatic train stop, when two cars to during the 3rd distance to a declared goal, (adjust W ₃Determine distance) J ₃Adhesive makes J _3-1Normally closed contact disconnects, and the main line contactless switch XLC outage on the locomotive running gear control panel is discharged, and locomotive shuts down.
