There are many factors affecting the performance of construction machinery. This paper discusses the influencing factors of the performance of construction machinery, in order to improve the utilization rate of construction machinery and achieve greater economic benefits.
With the rapid development of infrastructure construction such as roads, railways and aviation in China, various construction machinery have been widely used in the construction process, and the level of mechanization has been continuously improved, which has greatly improved the construction progress and construction quality. In the process of using construction machinery, due to various conditions and factors, it restricts the performance of construction machinery. Only by mastering the factors affecting the performance of construction machinery can we obtain the maximum economic benefit at the lowest cost.
1 The skill level of the operator
With the continuous development of science and technology and the wide application of new technologies, new materials and new processes, the types of construction machinery are more complete, the structure is more complicated, and the requirements for construction machinery operators are also improved. The operator must not only understand the structural composition, principle, performance, and mastery of the engineering machinery, but also have the ability to quickly diagnose and repair the failure of the construction machinery. The good technical level of the operator can greatly improve the utilization rate and integrity of the construction machinery, avoid the damage of the construction machinery caused by human factors, shorten the maintenance time and maintenance cycle of the construction machinery, and create good economic benefits for the enterprise. .
2 The moral cultivation of the operator
The working attitude and enthusiasm of the operators and the sense of responsibility have a great influence on the performance of the construction machinery. A qualified operator should have a high sense of responsibility and professional honor, be able to position himself and love his own work. Obey the management and design of the leadership, strictly abide by the company's various rules and regulations, conscientiously implement the safety operation procedures of construction machinery, safe production, and outstandingly complete the tasks assigned by the leadership.
Therefore, it is necessary to strengthen the quality education and training for operators, improve the enthusiasm and sense of responsibility of operators, constantly discover problems and shortcomings, and be brave enough to correct them, so as to more effectively improve the enthusiasm and initiative of operators, and better. Put into the work, improve the utilization rate and integrity of construction machinery, and achieve good economic benefits.
3 Maintenance of construction machinery
The maintenance quality of construction machinery is the premise and basis for the use of construction machinery. During the long-term use of construction machinery, the internal parts of the machinery wear, the clearance increases, and the coordination changes, the static balance and dynamic balance of the construction machinery are destroyed. Work stability, reliability, and mechanical productivity are all significantly reduced, and can even cause permanent damage to certain assemblies and components.
All enterprises must establish an effective management mechanism, strengthen the management of the maintenance of construction machinery, strictly implement various rules and regulations, and formulate annual maintenance plans and quarterly maintenance of construction machinery according to the use and integrity of construction machinery in recent years. Plan and maintenance plan for the current month, there are special personnel responsible for and inspection, maintenance work of construction machinery on time and on time, regular maintenance and inspection, and careful maintenance records of construction machinery.
4 Logistics support and material supply
Since most roads and railway construction sites are far away from cities and towns, the supply of equipment and the purchase of daily necessities will affect the use of construction machinery. Enterprise leaders and managers should often go deep into the frontline work. Care for the lives of employees, conduct extensive communication and communication, encourage the morale and enthusiasm of the employees, and improve the enthusiasm and efficiency of the operators.
The materials and accessories of construction machinery should be well guaranteed both in quality and quantity, avoiding the equipment being shut down or the equipment working abnormally due to factors such as unqualified quality, inconsistent size and insufficient quantity. Some assemblies Damage to parts and components has more serious consequences and causes unnecessary economic losses.
5 Work area of ​​construction machinery
Many modern large-scale construction machinery such as asphalt mixing equipment, stabilized soil mixing equipment, and combined crushers are all large in scale. The quality of each part is in the range of tens to hundreds of tons, and the requirements for the workplace are strict. The choice of the work site should fully consider the impact of the wind direction, rivers and surrounding buildings on the equipment, and the site should be as flat and dense as possible to avoid the inclination of the equipment due to heavy weight, severe vibration and other reasons during the use of the construction machinery. The foundation collapses, etc., causing unnecessary waste of rework and economic losses.
6 natural environment at the location
Factors such as extreme heat, cold, rain, snow, wind and altitude in the natural environment will have a great impact on the normal use of construction machinery. When the construction machinery is used under the conditions of extreme heat and severe cold, it should take necessary measures to protect the construction machinery, and make necessary adjustments to some parameters of the equipment according to the actual situation. The size of the wind has a very important impact on the normal operation of the construction machinery. When the wind is too large, the conveyor belt of the equipment will run off. In severe cases, the conveyor belt will tear or the conveyor belt will tilt and collapse. .
7 Energy equipment for construction machinery and equipment
Since the current power of large-scale highway construction machinery ranges from hundreds of kilowatts to several hundred kilowatts, there is a high requirement for the safety, stability and economy of the energy equipment that powers the construction machinery. Before the construction machinery is turned on, The system should be maintained and inspected for the energy device, and the generator's output power, work stability and safety should be thoroughly checked to provide strong power support for the normal operation of the equipment.
There are many factors affecting the performance of construction machinery. Only by mastering various factors affecting the performance of highway construction machinery can we make more adequate preparations and improve construction machinery in the actual construction process according to various factors that affect the performance of equipment. Utilization rate, reduce production costs, and achieve greater economic benefits.
