智能液压起拨道机的设计（Design of intelligent hydraulic lifting track machine） The design of intelligent hydraulic pulling machine 2011-07-20 17:17, 1, before 1 Preface Pulling operation is old line maintenance process of the construction of new railway lines and railway, for the whole line is the longitudinal section and plane geometry, eliminate uneven and bad direction, the design of lines reached the requirement of safe driving and common operation form. With the development of high speed and heavy load of railway, the profound change of track structure has put forward new requirements for railway construction and maintenance. From the manual operation of small machines to the use of tamping machines such as tamping machines, the construction technology and equipment have made great progress. But at present, all the railways in our country are both big and big, and the financial resources are neither possible nor technically necessary. As a result, the small hydraulic lifting machine is of great use in the operation of heavy sleepers and rails. Small hydraulic pulling machine overcomes the original small portable hydraulic lifting track device and michiyoshi dial setting road amount is small, labor intensity, low working efficiency, insufficient work quality is difficult to guarantee; without or for large tamping operation occasions, played an important role. But when it works, the amount of the road and the amount of the track are controlled by the workers, and the operation efficiency and the operation accuracy can not meet the requirements of the work. Laser collimation and hydraulic railway related units has been the development of the pulling machine, while focusing on the application of photoelectric automatic control technology to achieve pulling capacity, but because of its measurement and control system, measurement error, and can not be measured in the curve control, therefore has not been widely promoted. According to the requirements of the public works Departme
