【摘要】：钢丝绳牵引带式输送机是超长距离带式输送机中重要的一种类型,更是普遍应用于煤炭产业。其具有优良的输送性能:单机运输距离长和运输能力大;功率消耗少;运行平稳;倾斜、水平场合均适用;可在水平面内转弯以及便于实现自动化和环保。自1965年第一台GD型钢丝绳牵引带式输送机在我国问世,距今已有50多年的历史,然而近些年GD型钢丝绳牵引带式输送机的发展停滞不前,部分使用单位已将其淘汰或者替换,但其在超长距离输送上仍具有一定存在价值,故急需对其进行优化和改进。本文从设计、制造和使用方面指出了其缺陷,针对其有别于通用带式输送机的独特部件提出了优化改进方案:改进输送带使其不易脱槽;分析牵引钢丝绳扭转打滑机理,提出扭转打滑导致快速断绳的思想;采用防爆交流变频调速技术替代直流调速技术;为GD型钢丝绳牵引带式输送机加设防倒转装置系统,其核心部件是双楔半自动卡绳器,运用三维建模软件Solidworks建立双楔半自动卡绳器的三维实体模型,运用有限元分析软件ANSYS对卡绳器进行动力学分析,再利用ANSYS后处理软件对其进行瞬态动力学分析,以证明防倒转装置有一定的可行性和发展。通过优化改进方案,可以改进目前还在使用的GD型钢丝绳牵引带式输送机,在提高其适用性、可靠性和经济性基础上,使其在以后长距离输送上能有进一步的发展和利用。
[Abstract]:Wire rope traction belt conveyor is an important type of super long distance belt conveyor and is widely used in coal industry. It has excellent transportation performance: long distance and large transportation capacity; less power consumption; smooth operation; inclined, horizontal applications; can turn in the horizontal plane and easy to achieve automation and environmental protection. It has been more than 50 years since the first GD type wire rope traction belt conveyor was introduced in China in 1965. However, in recent years, the development of GD type wire rope traction belt conveyor has stagnated, and some units have eliminated or replaced it. But it still has some value in long distance transportation, so it is urgent to optimize and improve it. In this paper, the defects in design, manufacture and application are pointed out, and the optimization and improvement scheme is put forward for the special parts different from the general belt conveyor: to improve the conveyor belt so that it is not easy to take off the groove, and to analyze the mechanism of torsion and slip of the traction wire rope. The idea of fast rope breakage caused by torsion slip is put forward, the technology of anti-explosion AC frequency conversion speed regulation is adopted instead of DC speed regulation technology, and the system of anti-inversion device for GD type steel wire rope traction belt conveyer is added, the core component of which is double wedge semi-automatic clamp rope, The 3D solid model of the twin-wedge semi-automatic rope clamp is established by using the three-dimensional modeling software Solidworks, the dynamic analysis of the rope clip is carried out by using the finite element analysis software ANSYS, and the transient dynamic analysis is carried out by using the ANSYS post-processing software. In order to prove the anti-inversion device has certain feasibility and development. By optimizing the improvement scheme, we can improve the GD type wire rope traction belt conveyor which is still in use at present. On the basis of improving its applicability, reliability and economy, it can be further developed and used in long distance transportation in the future.
