Detailed Description

The invention is further described with reference to the following figures and specific embodiments:

as shown in fig. 1, in a "crane machinery safety monitoring and managing system GB/T28264-2017", the crawler crane safety monitoring and managing system includes an information acquisition unit, an information processing unit, an information output unit, an information storage unit, an information display unit, a remote transmission unit, an information output interface unit, and a remote control center. In the invention, the functions of the safety monitoring management system are expanded, and a wire rope visual identification module, a suspension arm straightness detection module, a host GPS module and a complete machine overturn alarm module are added.

In particular, crane ropes are important stress elements, and can cause serious safety accidents once the crane ropes are broken. As a replacement part, in the continuous use and wear, the traditional method is to judge whether the steel wire rope is scrapped or not and whether the steel wire rope needs to be replaced or not by operating drivers and inspectors through visual inspection and vernier caliper measurement. The wire rope visual identification module is used for acquiring data of a wire rope and analyzing the data; a plurality of steel wire rope cameras 1 are arranged near the steel wire ropes, a steel wire rope comparison data module is arranged in the signal processing unit, steel wire rope scrapping data information is arranged in the steel wire rope comparison data module, data collected by the steel wire rope cameras 1 are transmitted to the steel wire rope comparison data module to be compared, and the scrapping condition of the steel wire ropes is judged; if the collected steel wire rope data is matched with the steel wire rope scrapped data information, the steel wire rope comparison data module sends out an alarm signal, when the alarm signal is transmitted to the buzzer and the alarm lamp arranged on the information display unit, an audible and visual alarm is sent out, the relevant position and the photo condition of the steel wire rope are displayed on a liquid crystal display screen of the information display unit, an operator and an inspector are reminded to perform manual rechecking, and meanwhile, photos and videos of relevant sections are automatically stored.

The crane boom is used as an important stressed component, and the straightness maintaining effect of the crane boom is significant to safe use. The boom straightness detection module is used for monitoring the bending data of the boom, and the bending data is displayed on the information display unit; the suspension arm straightness detection module comprises a displacement sensor 2 arranged on the information acquisition unit. The method for detecting the bending degree of the suspension arm comprises the following steps: a steel wire rope inhaul cable is tensioned between the tail section and the head section of the suspension arm; measuring points are uniformly arranged on the steel wire rope inhaul cable at intervals, the steel wire rope inhaul cable is connected with the displacement sensor 2 at the corresponding position on the suspension arm at each measuring point, and the displacement sensors 2 are all positioned in a plane vertical to the steel wire rope inhaul cable; all the displacement sensors 2 are connected into the information processing unit through signal wires; when the suspension arm is in no-load state, all the displacement sensors 2 are reset to zero; when the suspension arm is hoisted, bending deformation is generated, and the displacement of the steel wire rope inhaul cable at each measuring point relative to the suspension arm is measured; because the two ends of the steel wire rope stay cable are fixedly arranged on the head section and the tail section of the suspension arm and cannot deform, and the steel wire rope stay cable is in a tensioning and straightening state, according to the measured displacement data, a deformation displacement diagram of each section of the pipe truss relative to the steel wire rope stay cable is drawn by computer software or by hand, the maximum bending deformation point and the bending deformation amount of the suspension arm can be monitored by using the deformation displacement diagram, and the bending degree of the suspension arm can be obtained.

The host GPS3 module comprises a host GPS3 arranged in a crane host and is used for positioning the position information of the crane, and the position information is transmitted to the remote monitoring center; the system is beneficial to flight inspection, and under the condition of not notifying in advance, mechanical management inspectors directly go to a host computer to perform onsite assault inspection on site according to the positioning information; and providing position information for the complete machine overturning remote alarm module.

According to the regulations of special equipment safety supervision regulations, the hoisting machinery is overturned integrally to belong to a large accident, and the large accident is investigated by special equipment safety supervision and management departments in provincial, autonomous and direct administration cities and related department organization accident investigation groups. The hoisting machinery is overturned integrally, personnel casualties and great property losses are often accompanied, the reputation of an enterprise is negatively influenced, and therefore rapid treatment response is extremely important. And the complete machine overturning alarm module is used for judging whether the crane is subjected to integral overturning or not and transmitting the generated integral overturning information to the remote monitoring center. A horizontal sensor 4 arranged in a crane host of a hoisting machinery safety monitoring management system is used for preventing the levelness of a crane body from exceeding 5 degrees in a normal operation state, if the sensor detects that the inclination of the crane body exceeds 30 degrees, the crane body is judged to be in an overturning state, a complete machine overturning alarm module automatically triggers a remote alarm mode, and meanwhile, according to positioning information of a host GPS3 module, the complete machine overturning alarm module sends a short message of 'an X-number crane positioned in X province and X city to overturn and please immediately start an emergency rescue plan' to a specified mobile phone number (such as unit leadership and mechanical safety management personnel). The level sensor 4 in the host computer is installed in the interior of the structure of the machine body, is not easy to be damaged by collision, and can not be damaged by direct impact when overturning. The complete machine overturn alarm module can also rearrange the level sensor 4 with higher reliability (the sensitivity does not need to be very high), and the level sensor and the host GPS3 module are together directly powered by the crane battery, so that the crane battery is not limited by the state of the engine, and the 24h state is ensured to be in a working state.

The remote alarm signals of the multiple cranes can also be connected to a remote server, and the remote server sends preset information to a specified mobile phone number. A single machine type: when the number of the cranes is less than 5, each crane independently sets a remote alarm signal, and the complete machine overturning alarm module sends alarm information to a specified mobile phone number; a multi-machine mode: when the number of the cranes is not less than 5, the alarm signal can be connected to the remote server through the network signal, and the remote server sends preset information to the specified mobile phone number.

In the embodiment, the steel wire rope comparison data module adopts a PLC controller, and the scrapped data information of the steel wire rope can be perfected through machine learning and training; for a multi-machine mode, the scrapped data information sharing of multiple cranes can be established, and the scrapped data information is continuously improved through a remote server, so that the comparison data is more accurate.
