Abstract
The utility model relates to a tool for maintaining railways, particularly a hydraulic track quickly-lifting and taking-up device with a quickly raising function. A one-way valve and a quickly raising switch are connected between a hydraulic accumulator and a hydraulic cylinder. Through an energy accumulating device, energy is accumulated in a resetting time after the hydraulic track quickly-lifting and taking-up device raises up for being used as a dynamic force for next quickly raise. When the hydraulic track quickly-lifting and taking-up device works, the hydraulic track quickly-lifting and taking-up device can quickly eliminate gaps between the hydraulic track quickly-lifting and taking-up device and a rail, and then the hydraulic track quickly-lifting and taking-up device can lift up the rail as a handle is turned. Therefore, a track lifting and taking up speed is raised and the operating time is saved.
Description
The utility model relates to a kind of railway track maintenance track lining special tool.
The height of railway track, level must conform to the line design requirement, and circuit is in using continuously, situation such as subgrade settlement will inevitably take place and influence the straight of circuit.This just needs the surfaceman often these circuits to be maintained.Want circuit to be lifted or dial directly, do not have special tool to be difficult to finish.Hydraulic track-switching device has adapted to the demand of maintenance of way operation and a kind of instrument of being widely adopted just.
In the prior art, its principle of the hydraulic track-switching device of each manufacturer production, structure are basic identical.But, required the track lining operating speed faster along with the arrival of train high speed.Existing hydraulic track-switching device has manifested the slow weakness of lifting velocity.Particularly in the operation, there is certain distance also not have when stressed with rail, also will slowly hoists at track lifting and lining tool.In the retrieval of prior art, do not find to solve the technical scheme of these weakness.
The purpose of this utility model is to provide a kind of fluid pressure type quick track lifting and lining tool.Energy when it can descend hydraulic cylinder stores, and makes the fluid pressure type track lifting and lining tool have quick lifting functions.
The purpose of this utility model is achieved in that and installs a cover hydraulic accumulating device additional between the hydraulic cylinder of hydraulic track-switching device and fuel tank, when the hydraulic cylinder that rises resets, to the accumulation of energy of accumulator topping up, after accumulator was full of, hydraulic oil can be got back in the fuel tank by one way valve.When the need piston rises, open the valve of accumulator to the hydraulic cylinder topping up, the liquid in the accumulator is realized hoisting fast then fast with hydraulic cylinder jack-up.
The utility model is owing to adopted accumulator, and the power that the idle work when utilizing hydraulic cylinder to reset hoists once more fast as hydraulic cylinder is so the energy effective use of energy sources has been accelerated a track lining operating speed.
Structural principle of the present utility model is provided by following examples and accompanying drawing.
Accompanying drawing is the schematic diagram according to the quick track lifting and lining tool of fluid pressure type that the utility model proposes.
Describe in detail according to detail and the working condition that the utility model proposes below in conjunction with accompanying drawing.
The quick track lifting and lining tool of fluid pressure type comprises hydraulic pump (1), hydraulic cylinder (2), the valve that resets (3), one way valve (4), fuel tank (5), accumulator (6), one way valve (7), one way valve (8), rises switch (9), throttle orifice (10) soon.
During use, the valve (3) that will reset earlier, rise switch (9) soon and close, during work, hydraulic pump (1) is sent hydraulic oil to hydraulic cylinder (2) through one way valve (4), and hydraulic cylinder rises rail jack-up; When needing to descend, open the valve that resets (3), hydraulic oil refluxes under the rail action of gravity fast, the throttling action through throttle orifice (10), and part oil enters accumulator (6) through one way valve (8), a part of oil sump tank (5), hydraulic cylinder resets.When reusing, the quick track lifting and lining tool of fluid pressure type is put under the rail, hydraulic cylinder and rail bottom have a segment distance, at this moment, open the fast switch (9) that rises, the pressure oil in the accumulator enters hydraulic cylinder through one way valve (7), and hydraulic cylinder will rise fast and push up below the rail, and then the operation hydraulic pump works, lifting velocity is accelerated.
Claims (3)
1, the quick track lifting and lining tool of a kind of fluid pressure type, this device is made up of hydraulic pump (1), hydraulic cylinder (2), fuel tank (5), valve etc., it is characterized in that inserting in system a hydraulic accumulator (6).
2, device according to claim 1 is characterized in that inserting one way valve (7) and rises switch (9) soon between hydraulic accumulator (6) and hydraulic cylinder (2).
3, device according to claim 1 is characterized in that being equipped with one way valve (8) and throttle orifice (10) between hydraulic accumulator (6) and fuel tank (5).
