ZT-TG500推管机的研制

介绍了ZT-TG500型推管机的参数、工作原理、主要结构构成及其功能、关键技术、用途。推管机在非开挖施工过程中，对非开挖设备起到了辅助的作用，能够“营救”施工中卡死的管线，也可以协助非开挖设备推动管线前进，保证工程的成功。该推管机采用电液比例控制技术，能够实现零到最大无级调速，给施工带来了很多的益处；卡瓦橡胶硫化涂覆技术，保证了卡瓦夹紧时不损坏钢管表面的防腐层，同时保证了足够的夹持力而不打滑；双油缸同步防扭技术，采用滑动导轨与大型分流阀的机液控制方法，来实现油缸的零阻力，使油缸的推力能有效地应用到工程中。通过青州水管铺设与穿越松花江的自来水管铺设的现场应用，取得了良好的效果。

Development of ZT-TG500 Type Pipe Pushing Machine

This paper mainly introduces ZT-TG500 type pipe pushing machine about its parameters, working principles, main structure and functions, key technology and the usage. This machine plays an auxiliary role for trenchless equipments in the trenchless construction process, can save the stuck section in pipeline construction and also can help trenchless equipment push the pipeline forward, so as to ensure the success of the project. Due to the use of electro-hydraulic proportional control technology, zero to maximum stepless speed regulation can be achieved, which has brought a lot of benefits to the construction. Vulcanized rubber vulcanization coating technology is used, by the key data in the test, to meet the parameter requirement in practical engineering; with double oil cylinder synchronous anti-torsion technology, using mechanical hydraulic control methods of sliding rail and large shunt valve to realize zero resistance of the cylinder, which can effectively provide the cylinder thrust for the project. This pipe pushing machine is applied in Qingzhou water pipe laying and water piper laying crossing Songhuajiang with good effect.
