Description

A Safety Monitoring System for Rescue Cranes

technical field

The utility model relates to the technical field of rescue cranes, in particular to a safety monitoring system for rescue cranes which is particularly suitable for use at night and has high safety.

Background technique

Ensuring the safety of railway lines is an important task. Rescue cranes, as the main rescue equipment, play an irreplaceable role in quickly repairing line obstacles, lifting accident trains, and ensuring safe operation of railways.

Due to the large-scale equipment of traditional rescue cranes, the driver's working space is relatively small during the rescue process, but it needs a large space for rescue work such as slewing and hoisting of train accident cars. In some cases (especially at night), the driver Or the light is not enough) it is very easy to cause visual blind spots during operation, so generally multiple staff members are required to coordinate and command each other at the rescue site, which reduces the operating efficiency of the driver on the one hand, and increases the cost of personnel on the other hand; at the same time, due to construction The noise at the scene leads to barriers to communication, which may cause collisions between the hoisted accident vehicle and surrounding people, and bring various hidden dangers to safety rescue. In addition, traditional rescue cranes generally use multi-leg fiber slings. The slings that have been used many times are prone to the risk of breaking and falling off of some of the slings, and it is not easy to find out in daily maintenance, so it is very easy to cause a single-leg sling to break off. The car was broken due to excessive force, causing the accident car to fall instantly, posing a great safety threat to the personnel on the scene.

The pedestrian detection module can be designed and developed using the deep learning algorithm based on machine vision technology, which can more accurately detect whether there are potential safety hazards in the image data of the 360° camera, and further ensure the safety of the rescue workers.

As a further improvement of the above safety monitoring system for crane rescue, an alarm controlled by the monitor is also included. Intelligent control of the alarm through the monitor can further ensure the safe and efficient rescue work.

As a further improvement of the above-mentioned safety monitoring system for rescue cranes, the alarm includes a buzzer alarm located in the driver's compartment and/or an alarm light outside the driver's room, and the alarm light is connected with a tension sensor and a 360° camera , radar rangefinder, wireless handheld walkie-talkie to any number of devices connected. The warning effect of the buzzer alarm is good, which can make the driver discover the abnormal situation in time, and the warning light is especially suitable for reminding the commander and the driver at night, so as to avoid the influence of various noises on the rescue site from affecting the warning effect. Further, the warning light is an LED warning light.

As a further improvement of the above safety monitoring system for crane rescue, the 360° camera is an intelligent infrared camera equipped with a light intensity detection module. At this time, the 360° camera can detect the light intensity at the scene, and if the light intensity is low, the infrared function will be automatically turned on to further adapt to night rescue work.

As a further improvement of the above-mentioned safety monitoring system for crane rescue, the radar range finder includes a permanent magnet layer, a radar host layer, a radar transmitter and a wireless antenna, and the radar range finder passes through the permanent magnet layer Adsorbed on the outside of the suspended object.
