Overhead cranes are the setting guarantee for the general configuration in my country's construction industry. In the operation of my country's industrial systems, they have the characteristics of wide coverage, high application degree and fast popularization speed. They are the basic equipment for the development of major industries in my country. It has successfully covered all corners of land, sea, air, civil, military, etc. On the other hand, bridge cranes are an important guarantee for the safe and effective operation of my country's construction engineering systems, running through the entire heavy industry industry, ensuring the safe operation of industrial systems. Pay attention to the analysis and solution of the operation failure of the overhead crane, in order to effectively avoid the occurrence of dangerous accidents, maintain the stable, smooth and safe operation of the heavy industry working system, and also reduce the economic loss of the enterprise and ensure the personal safety of the staff.
1 Common problems and solutions of overhead cranes
1.1 Common problems and solutions of hooks
The hook is the most commonly used fetching device for overhead cranes. It bears the entire load of the hoisting and transportation. In the process of use, once the hook is damaged and broken, it is easy to cause major accidents. The reason for the damage and fracture of the hook is that the hook is cracked, deformed, damaged and fractured due to friction and overloading. In order to prevent the hook from malfunctioning, it is necessary to strictly prohibit overloading during use. During the inspection process, pay attention to the opening of the hook and the wear of the dangerous section. At the same time, the hook should be annealed regularly. If the crack is found, it should be scrapped according to GB10051-88, and the hook should not be welded and repaired. The inspection of the hook by the special equipment manager shall determine whether the hook can be used according to the requirements of GB10051-88.
1.2 Crane brake failure and measures
The main reasons for the failure of the brake and the serious wear of the pin shaft are: because the brake is a key component of the bridge crane in a high-frequency working state, the crane will generate a large amount of dynamic load during braking, and it will be under long-term working frequency. In the case of cranes, under the condition of large loads and impacts on various parts, the pins are severely worn, which makes the brakes fail.
In the prevention and solution measures of this fault, firstly, the equipment inspectors of the bridge crane are required to seriously deal with the braking requirements of each equipment of the crane, make adjustments in strict accordance with the requirements in the operation manual of the bridge crane, and carefully check the quality of the crane components. The size of the gap between the moving pad and the brake wheel. In order to ensure the normal work of the brake under small dynamic torque, the compression length of the main spring can be changed by adjusting the nut. In addition, it is necessary to regularly use lubricant for each corresponding part of the crane to ensure its normal working performance, regularly check the completeness of the brake and its components, and replace the brake belt and pin shaft that is severely worn in time, and strictly Replacing components according to the scrapping standard of crane brake parts ensures the renewal of crane components and makes them operate safely and effectively.
1.3 The oil leakage of the reducer of the crane and the solutions
The main reasons for the oil leakage of the reducer are: first, due to the unreasonable design of the components, such as no ventilation holes or too small ventilation holes, etc., so that the internal and external pressures of the reducer cannot be balanced, and the phenomenon of lubricating oil will overflow; The manufacture of the crane does not meet the strict design standards, which will lead to insufficient accuracy of the joint surface of the crane box, resulting in the loose seal of the reducer components, resulting in leakage; the third is the improper use and maintenance of the crane reducer As a result, under the high-frequency operation of the crane, the dust accumulation of the ventilation hood will be too much, which will cause the ventilation hood to be blocked, so that a higher pressure will be generated inside the machine and oil spillage will occur.
In the prevention and resolution of failures, it is required to continuously improve the design standards of bridge cranes, and set up ventilation equipment on the reducer hole cover of the crane to keep the inside and outside of the box balanced and smooth to avoid oil leakage; in addition, it must be done in time. In the maintenance work of the crane, the maintenance personnel are often organized to check the ventilation holes of the reducer, pay attention to the stability of each gasket, avoid its failure in work, and check the tightness of the bolts in time to ensure the normal operation of the components.
2 Strengthen and consolidate the operation and maintenance of overhead cranes to ensure their stable and healthy development
First, establish a complete management system for crane operation and maintenance, and strengthen personnel training and education.
In order to make the bridge crane operate safely and effectively, it is necessary to establish a complete set of safety management measures on the basis of constantly summarizing management experience, improve employees' awareness and operation and maintenance management skills, and use accurate operation steps as the basis for decision-making. Regular inspection and maintenance of crane electrical equipment operation and protection, and continuous accumulation of data for analysis, so as to establish a crane protection system and prepare for equipment maintenance. At the same time, use safety management and other means to improve the effectiveness and convenience of crane operation. It is an important guarantee for the establishment of a comprehensive, systematic, safe and stable operation system of overhead cranes.
Secondly, constantly update and introduce new technologies, learn from and absorb foreign practical experience, and promote the update of equipment technology.
With the continuous improvement of my country's scientific and technological level and the vigorous development of social industries in various fields, the installation and technical level of bridge cranes must also follow it, not only in the update of the use of power system equipment, but also in the upgrading of advanced technology. It is also necessary to vigorously strengthen. In recent years, the installation of bridge cranes in my country has been striving to achieve networked scientific and effective management and control, so that the scientific safety management of the crane power system has changed from the original manpower-based transformation to today's networked and artificial intelligence. A set of comprehensive and new technological innovation support guarantees have been established to ensure the stable and healthy operation of the crane power system.
In addition, strengthen the daily maintenance and maintenance of the crane to ensure the construction of the safety system of the machine.
On the basis of long-term high-frequency work, due to differences in natural and human factors in various environments, climates, geography and other aspects, various crane system failures are also caused. This requires us to pay attention to strengthening the daily maintenance and maintenance of the crane in actual work to ensure the safety of the machine and improve the efficiency of the machine, so as to find and solve the power grid operation failure in time, and ensure the stability of the machine system. Provide a good operating environment and necessary guarantee for the normal operation of the crane.
