Hydraulic tamping machine in the world the earliest
XYD-Z type hydraulic tamping machine, in 1972 by the Shanghai Railway Bureausuccessfully developed. The beginning of a hydraulic tamping machine, after the reform by taking this name, specifically for ramming for railway sleeper. The peak time of 180 root. It has the advantages of simple operation, practicality, many countries are willing to buy the patent or imported at jin. It is the world's earliesthydraulic tamping machine.
Hydraulic tamping machine for tamping machine in the world the earliest (BallastTamper) is mainly used for construction of concrete pouring and railway maintenance process of tamping sleeper below Shi cha. For the railway industry belongs to a kind of special maintenance machinery, mainly used for tamping operation for railway ballast.
The working principle of tamping machine is the driving force generated by the engine, from passive disk is transferred to the gear box, the gear reducer, by turning the crankshaft gear and drives the connecting rod, piston, pistoncompressor gas charged up and down movement, the impact pickaxe shank,pickaxe for high frequency, high energy impact on objects, thus implementation of the operation object tamping.
Tamping machine according to the species can be divided into flexible shaft,hydraulic tamping machine, tamping machine, internal combustion tampingpickaxe, electric tamping pick.
Before the last century 60's, the maintenance of railway line basically relies on the human. Maintenance workers the extremely heavy workload, the main reason is the maintenance of railway line work object too bulky thick. Labor intensitymaintenance line, low work efficiency, work quality is not high. With thedevelopment of railway industry, the railway maintenance work after the 60's of the last century, made the tough steps.
After entering 80 age, along with the increase of China's railway transportation density, busy line maintenance work using traditional methods and means have been unable to complete. At the same time, the increasing modernization of track structure but also to the operation quality and maintenance machinery put forward higher requirements. In this situation, the inevitable maintenance mechanization work of our country in transformation. In 1983 signed a RM80 typeroad cleaning machine, 08-32 type pulling leveling tamping machine, ballastdynamic stability of car of DGS62N type and SSP103 type with ballasted plasticcar each 1 units of the order contract. The following year, the second half of the year, this batch of imported from Austria's large track maintenance machinery inorder to reach Tianjin Xingang, attached to the Shenyang Railway BureauJinzhou first line overhaul period of 4, the Beijing Railway Bureau Beijingmechanized maintenance team 7. Creating a new situation of China Railway large maintenance machinery operation.(责任编辑：最有料)
