| Under the new situation of railroad train's increasing speed completely, freight train's typical breakdown is increasing obviously, and affects the safety of train working. In the railway's train checking a large quantity of hook buffer device is changed frequently, and then at present dismounting hook buffer device adopts three parts: rotary hook couple, two-way synch elevator, mobile lift platform truck. It needs three people working at the same time; at sometimes it needs bridge lifting machine to cooperate. It needs more eighty minutes to change a suit of hook buffer device. And high laboring strength, low work efficiency and work way can't meet production demand.So, we don't lose the chance to improve the system unitization of the vehicle unit, reinforce the safe technical equipment, improve the vehicle state and checking equipment, boost the safe security ability and enhance the check before acceptance in craft to big, middle, small repair truck. This will strengthen the safe basic equipment of our country's railway. For the sake of the railroad high speed's orientation, according to the level's demand "the main terminal station should equip the necessary frock, equipment we by ourselves research to manufacture standing fixing ten works packing that moves the hydraulic to the hook buffer set of separate-installed machine, guaranteeing the quantity of the check fixing, increasing workers of standing fixing in the efficiency and laboring productivity, alleviating workers' laboring strength and increasing the quantity of fixing the train to aim.The main engineer of self-propelled hydraulic hook buffer separate-installed machine adopts hydraulic theory. Work hydro- cylinder makes use of single and double function's hydro- cylinder to pressure. Then it can easily enter the train's bottom and finish the dismounting work of the hook buffer device.Self-propelled hydraulic hook buffer separate-installed machine's . running parts adopt the hydraulic motor drive. There is the clutch operation, hand-pushed andself-running. And it can move transversely and run flexibly; front and back hydraulic cylinders adopt doublergrade and double-function cylinders. So it not only ensures lift course, but also lowers the equipment's height. Left and right jacking hydraulic cylinders are working simultaneously. This makes adjustable grabber block the hook buffer device and dismount the hook buffer device effectively.The self-propelled hydraulic hook buffer separate-installed machine, the whole unit's construction is tightly packed, operation convenience and convenient for maintenance. This matches the railroad rule on the standing fixing. The whole motion is stable, quick and easy to operate. Adopting the hand-pushed motorcycle type can move manually and automatically. It solves the problem or the small mouth between the vehicles in the usual standing fixing ,the disadvantage in the chancing the whole hook buffer suit, having the good usage function, dependable highly, the work of hook buffer's whole separate-install to all kinds of freight train. The whole motion saves time and labor , shortens the work time and reduces workers' laboring strength. This meets the whole suit's dismounting craft of hook buffer and places the validity to increase the productivity in standing fixing hook buffer labor that insure the conveyance safety to have to promote the function.During the research, define the separate-installed machine's main technical parameter and running parameter and choose the relevant component by stressed analysis and capacity measurement to the hook buffer device. Define the separate-installed machine's final design program by experiment again and again and analysis.Developing the self-propelled hydraulic hook buffer separate-installed machine meets the expected design's aim and demand, and gain high opinion by operating on the spot. At the same time Self-propelled hydraulic hook buffer separate-installed machine also has passed the technical achievement test of Zhengzhou railway bureau. The test considers this hydr... |
