苛刻 ” ，对各种类型的作业平台要求也不尽相同，总的来说主要有大作业高度高、大作业范围、结构小巧紧凑、可通过性好、无污染、零排放和节能减排等。 In recent years, with the construction of urban infrastructure and the rapid development of the national economy, not only has the demand for aerial work machinery increased year by year, but also the requirements for aerial work machinery have become more " harsh " , and the requirements for various types of operating platforms All the same, in general, there are high operating height, large operating range, small and compact structure, good passability, no pollution, zero emissions, energy saving and emission reduction. No matter what the product is, quality is the key. For lay friends, how do you know if the high-altitude car you bought is qualified?
升降平台 必须做好的几点技术： Several techniques that a qualified lifting platform must do well:
的发展过程中，存在着各种共性或者关键技术。 During the development of the lifting platform , there are various commonalities or key technologies. 升降平台 的质量，加快 升降平台 的技术进步, 让客户知道购买到的 升降平台 是不是合格，做了以下几点介绍： In order to better improve the quality of the lifting platform , speed up the technical progress of the lifting platform , and let customers know whether the purchased lifting platform is qualified, the following points are introduced:
Some techniques that must be done:
(1) Leveling mechanism
In order to ensure the safety and stability of high-altitude operations, the bottom surface of the working platform must always be horizontal during lifting and working. 升降平台 ，目前已成为调平机构发展的趋势。 The electro-hydraulic proportional leveling mechanism, which is one of the electro-hydraulic leveling mechanisms, has a continuous and stable leveling process, good leveling performance, high control accuracy, and fast dynamic response. It is suitable for various forms of large-height lifting platforms . Become the trend of leveling agency development.
(2) Power automatic control system
According to the working state and working conditions of the transmission device and hydraulic system, the engine output power is automatically adjusted to adjust the engine speed in real time to achieve the effect of energy saving and noise reduction.
(3) Security aspects
① Computer fault diagnosis system. The system better realizes the humanized design. The operator can infer the potential fault hazards only through the comprehensive analysis of alarm signals such as indicator lights, vision and hearing, so that the operator can work more focused.
② Automatic weighing system. Real-time automatic weighing and display of the load of the working platform. When the rated load is exceeded, an alarm signal is issued and the occurrence of misoperation is restricted to ensure the safety of high-altitude operations.
Several techniques to highlight product performance:
升降平台 的结构设计中，伸展结构液压缸支点位置的确定。 (1) In the structural design of the lifting platform , the position of the fulcrum of the hydraulic cylinder of the extension structure is determined. The position of the fulcrum of the hydraulic cylinder has a certain effect on the selection of the hydraulic cylinder, the force of the shear fork arm and the stability of the vehicle. It is necessary to make the hydraulic cylinder equal to the force when it is in the extreme position, or The force applied during the work is basically unchanged.
(2) Load-sensing transmission system. Real-time detection of load status and automatic adjustment of vehicle speed and engine flywheel torque to achieve low-speed high-torque or high-speed small-torque power output.
(3) CAN bus distributed control technology. 实现预期设计功能的关键就是微电控制系统， CAN 总线分散控制技术使整车系统布线更少、更简洁、更紧凑的同时提高系统的可靠性。 The key to the lifting platform to achieve the expected design function is the micro-electric control system. The CAN bus decentralized control technology makes the vehicle system wiring less, simpler and more compact, while improving system reliability.
升降平台 将会趋于以下三个方向去发展： In the future, the lifting platform will develop in the following three directions:
向大高度和特殊 升降平台 发展。 (1) Development towards large heights and special lifting platforms . 升降平台 、越野式 升降平台 、蜘蛛式 升降平台 及履带式 升降平台 。 Such as hybrid arm lifting platform , off-road lifting platform , spider lifting platform and crawler lifting platform .
车载式或牵引式逐渐发展成结构小巧紧凑的自行式。 (2) Vehicle-mounted or traction type has gradually developed into a compact and compact self-propelled type.
驱动方式向无污染、零排放、节能减排的电机驱动发展。 (3) The driving method is developed towards a motor that is pollution-free, zero emission, energy saving and emission reduction.
