Background

The crane is a lifting and transporting device frequently used in daily production of factories, and a plurality of cranes can be operated on the same track of a plurality of large factories. The anti-collision protection of the crane in the prior art mainly takes a cushion pad and a travel switch triggered close to the end of a track as main parts, the cushion pad has the main characteristics that the cushion pad plays a role in buffering and damping after collision, is easy to damage after being impacted by a large force, cannot play a role in reminding a driver that danger is about to occur and preventing the danger from occurring, the travel switch triggered at the end of the track can only allow the crane to stop at the end of the track, prevent the crane from colliding the end of the track, cannot prevent two cranes on the same track from colliding, and cannot well protect life and property safety. Therefore, there is a need in the art for a new solution to solve this problem.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a crane electron anticollision and initiative brake equipment can be applied to on all kinds of rail crane, can effectively solve among the prior art buffer can not remind the driver to have danger will take place and prevent danger and take place and the travel switch that the track end triggered can not prevent to collide with two cranes on the track problem.

The technical scheme adopted by the utility model for solving the technical problems is that the electronic anti-collision alarm and active brake device for the crane comprises a photoelectric proximity switch with the sensing distance of 10 meters, a photoelectric proximity switch with the sensing distance of 5 meters and an acousto-optic alarm; the photoelectric proximity switch with the induction distance of 10 meters is arranged at the root of the anti-collision buffer cushion, the audible and visual alarm is arranged at the left side and the right side in the cab, and a normally open contact of the photoelectric proximity switch with the induction distance of 10 meters is connected with the audible and visual alarm; the photoelectric proximity switch with the induction distance of 5 meters is arranged beside the photoelectric proximity switch with the induction distance of 10 meters, a power supply of the photoelectric proximity switch with the induction distance of 5 meters is connected with a normally open contact lower port of a gear shifting contactor with two or more traveling gears of the crane in parallel, and the normally open contact of the photoelectric proximity switch with the induction distance of 5 meters and a travel switch of the crane are connected into the same point of a control loop.

Furthermore, the photoelectric proximity switch with the sensing distance of 10 meters, the photoelectric proximity switch with the sensing distance of 5 meters and the audible and visual alarm are two.

Through the above design scheme, the utility model discloses following beneficial effect can be brought: the anti-collision active braking device can predict danger and actively brake, the acousto-optic alarm device can remind a driver of the danger of proximity on the left side or the right side, and the anti-collision active braking device is started from the second advancing gear, so that accidental severe collision caused by the fact that the speed of the crane is too high can be effectively prevented. The crane has the advantages of preventing collision accidents in the working process of other cranes due to the fault operation of unconsciousness or the fault or the overhaul of one crane on the same track, protecting the safety of life and property, along with simple structure and good economical efficiency.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments, it should be understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

An electronic anti-collision alarm and active brake device for a crane comprises a photoelectric proximity switch 2 with the sensing distance of 10 meters, a photoelectric proximity switch with the sensing distance of 5 meters and an audible and visual alarm 3; the photoelectric proximity switch 2 with the induction distance of 10 meters is arranged at the root of the crash cushion 1, the audible and visual alarm 5 is arranged at the left side and the right side in the cab 4, and the normally open contact of the photoelectric proximity switch 2 with the induction distance of 10 meters is connected with the audible and visual alarm 5; the photoelectric proximity switch 3 with the induction distance of 5 m is arranged beside the photoelectric proximity switch 2 with the induction distance of 10 m, a power supply of the photoelectric proximity switch 3 with the induction distance of 5 m is connected with the lower opening of the normally open contact of the gear shifting contactor with the traveling gear of the crane in parallel, and the normally open contact of the photoelectric proximity switch 3 with the induction distance of 5 m and the travel switch of the crane are connected into the same point of a control loop.

Further, the photoelectric proximity switch 2 with the sensing distance of 10 meters, the photoelectric proximity switch 3 with the sensing distance of 5 meters and the audible and visual alarm 5 are all two.
