The embodiment of the utility model provides a safety device of overhead traveling crane driving area, as shown in figure 1, include: safety barriers, controller 102, and a distance measuring device.
The safety fence comprises a boundary fence 1011 arranged around a safety channel below a travelling area of the overhead travelling crane and a safety door arranged on the boundary fence 1011, wherein the safety door comprises a first door body 1012 and a first door lock 1013 thereof, a second door body 1014 and a second door lock 1015 thereof, and the first door body 1012 and the second door body 1014 are respectively arranged at two ends of the safety channel. The direction of the safety channel is perpendicular to the direction of the traveling area of the overhead traveling crane, and the safety channel is located below the traveling area of the overhead traveling crane.
The ranging device comprises a first ranging sensor 1031 and a second ranging sensor 1032, wherein the first ranging sensor 1031 and the second ranging sensor 1032 are respectively arranged at two ends of a crane rail guardrail, and the crane rail guardrail is arranged at two sides of a crane driving area.
The first ranging sensor 1031 and the second ranging sensor 1032 are both specifically radar detectors, and are used for detecting whether a crown block passes through above the safety passage.
The controller 102 is connected to a first distance measuring sensor 1031, a second distance measuring sensor 1032, a first door lock 1013, and a second door lock 1015, respectively.
On one hand, the controller 102 receives the ranging signal from the first ranging sensor 1031 or the second ranging sensor 1032, and the controller determines whether an overhead traveling crane passes through the safe passage according to the ranging signal. On the other hand, when it is determined that the overhead traveling vehicle passes through the upper part of the safe passage based on the distance measurement signal, the first door lock 1013 on the first door body 1012 and the second door lock 1015 on the second door body 1014 are controlled to be locked. At this time, the person is prohibited from entering the safe passage of the overhead traveling crane driving area. So as to avoid unsafe accidents caused by personnel entering the area.
The first door lock 1013 and the second door lock 1015 are electromagnetic locks.
The first door lock 1013 is disposed at the closed end of the first door body 1012 and the second door lock 1015 is disposed at the closed end of the second door body. The principle of the electromagnetic lock is that the electromagnetic lock is attracted when being powered on, so that the door body locks the door, and the attraction force is lost when the power is off, so that the door body is opened.
Specifically, the first door lock 1013 is bolted to the closed end of the first door body 1012, and the second door lock 1015 is also bolted to the closed end of the second door body 1014.
This safety barrier still includes: the door closing device comprises a first door closer and a second door closer, wherein one end of the first door closer is connected with a first door body 1012, and the other end of the first door closer is connected with a boundary fence 1011; the second door closer is connected to the second door body 1014 at one end and to the boundary rail 1011 at the other end.

The first door closer and the second door closer can adopt electric lead screws, the principle of the electric lead screws is that the electric lead screws can be stretched or contracted when being electrified, and stretching and contraction are realized by controlling forward rotation or reverse rotation of a motor, so that a door body is driven to be closed.
The first door closer and the second door closer are automatic speed-adjustable door closers, can buffer the door closing speed, and automatically close to the position where the electromagnetic lock can be closed and attracted fully after the first door body 1012 and the second door body 1014 are opened.
The first door body 1012 is connected with the boundary fence 1011 by a hinge, so that the first door body 1012 moves relative to the opening and closing door of the boundary fence 1011; the second door body 1014 is connected with the boundary fence 1011 by a hinge, so that the second door body 1012 can move relative to the opening and closing door of the boundary fence 1011.
In a specific embodiment, the safety device further comprises an audible and visual alarm 104, the audible and visual alarm 104 is disposed on the outer side of the first door body 1012 or the outer side of the second door body 1014, and the audible and visual alarm 104 is connected to the controller 102. The voice audible and visual alarm 104 is controlled by the controller 102 to perform voice audible and visual alarm when the controller determines that a crown block passes through above the safety passage based on the ranging signal of the first ranging sensor 1031, so as to remind passing people to avoid the crown block in time.
Meanwhile, when it is determined that overhead vehicles pass through the upper part of the safety channel, the controller 102 controls the first door lock 1013 and the second door lock 1015 to be locked, specifically, the electromagnetic lock is attracted by electrifying. People are prevented from entering the safe passage.
The safety protection device further comprises a first emergency exit button 1051 and a second emergency exit button 1052, wherein the first emergency exit button 1051 is disposed inside the first door body 1012, the second emergency exit button 1052 is disposed inside the second door body 1014, and both the first emergency exit button 1051 and the second emergency exit button 1052 are connected to the controller 102. When it is determined that overhead vehicles pass through the upper part of the safe passage, if people pass through the safe passage at the moment and the first door body 1012 and the second door body 1014 are closed at the moment, people in the safe passage can escape from the first door body 1012 in an emergency when the first emergency exit key 1051 is pressed, and people in the safe passage can escape from the second door body 1014 in an emergency when the second emergency exit key 1052 is pressed, so that safe evacuation is realized.
The controller 102 determines that the voice audible and visual alarm 104 is turned off at the end of passing of the overhead travelling crane above the safe passage based on the ranging signal of the second ranging sensor 1032, and at the same time, the controller 102 controls the first door lock 1013 and the second door lock 1015 to be opened, that is, the electromagnetic lock is turned off and opened. The normal passage of the safe passage is ensured.
The safety protection device for the travelling area of the overhead travelling crane plays an important role in preventing accidents caused by factors such as unsafe behaviors of people and unsafe states of objects, essentially eliminates the occurrence of people and vehicles conflict on a safety channel of the travelling area of the overhead travelling crane, and has good effect in the operation process after the transformation is finished.
