  当前国度对水利、水电、桥梁等根底设备建立投资力度很大,在其施工、维修和改造过程中,大扭矩紧固件的拆装作业必不可少同时又非常艰巨。传统的人力办法拆装,不只劳动强度大,作业效率低,本钱高,而且由于猛烈的振动和噪音,经常使紧固件报废,直接影响装置、维修工期,并不可防止地损伤毗连的零部件,影响以至毁坏原工程构造的力学均衡;同时难以依据设计请求精确控制装配力矩。因而,设计开发可以输出强大转矩,同时操作笨重、平安牢靠和通用性强的拆装工具———便携式大扭矩液压扳手,具有重要的理想意义。

  At present, the country invests heavily in the establishment of water resources, hydropower, bridges and other basic equipment. In the process of construction, maintenance and transformation, the disassembly and assembly of large torque fasteners is indispensable and arduous at the same time. The traditional manpower method of disassembly and assembly not only has high labor intensity, low operation efficiency and high cost, but also often causes the scrap of fasteners due to violent vibration and noise, which directly affects the installation and maintenance period, and can not prevent the damage of adjacent parts and components, thus affecting or even destroying the mechanical balance of the original engineering structure; at the same time, it is difficult to rely on. Accurate control of assembly torque according to design requirements. Therefore, the design and development of portable large torque hydraulic wrench, which can output powerful torque and operate bulky, safe, reliable and versatile disassembly and assembly tools, has important ideal significance.

  液压扳手的系统组成和主要性能指标综合剖析研讨实践操作状况和多种计划,我们以为理想的设计计划是:应用液压作为动力源,依托棘轮棘爪机构完成紧固件拆装作业的单向间歇运动,并经过对反作用力臂和套筒的系列化设计,使该便携式大扭矩液压扳手依据不同的作业环境和工作对象,可普遍应用于水利水电、冶金、建筑、桥梁、矿山、水泥等行业中大中型机械设备及钢构造的装置、维修工程。
  The system composition and main performance indexes of hydraulic wrench are comprehensively analyzed and discussed. Practical operation and various plans are discussed. We think that the ideal design plan is: using hydraulic pressure as power source, relying on ratchet pawl mechanism to complete one-way intermittent movement of fastener disassembly and assembly, and through the serialization of reaction arm and sleeve. The portable hydraulic wrench with large torque can be widely used in the installation and maintenance of large and medium-sized mechanical equipment and steel structure in the fields of water resources, hydropower, metallurgy, construction, bridge, mine, cement and other industries according to different working environments and objects.
  液压扳手采用超高压液压技术目前,我国以大于&!’() 为超高压液压压力界线值,在现代技术范畴和工业消费中,超高压液压技术已是不可短少。其主要技术特性和请求是:严厉的密封,超高压小流量,请求专用液压介质。液压系统以一定的功率工作时,由于压力很高,所以流量就很小,其流量普通在&* + ,-. 以下。普通液压油在超高压力下活动性锐减,极大水平上影响着液压系统的容积效率,体积紧缩量不能疏忽。应选用特殊专用介质,采用柱塞副构造。由于柱塞副对超高压力下的密封具有良好的顺应性,并有强大的构件强度和刚度。 构造和运动机构的设计特性。
  Hydraulic wrench adopts ultra-high pressure hydraulic technology. At present, in our country, the limit value of ultra-high pressure hydraulic pressure is greater than &! (). In the field of modern technology and industrial consumption, ultra-high pressure hydraulic technology is indispensable. Its main technical characteristics and requests are: strict sealing, ultra-high pressure and small flow, requesting special hydraulic media. When the hydraulic system works at a certain power, the flow rate is very small because of the high pressure. The flow rate is usually below &*+, -. The activity of ordinary hydraulic oil decreases sharply under ultra-high pressure, which greatly affects the volume efficiency of the hydraulic system. The volume contraction can not be neglected. Special special medium and plunger pair should be used. Because the plunger pair has good compliance to the seal under ultra-high pressure, and has strong strength and stiffness of components. Design characteristics of construction and motion mechanism.
