Abstract
The utility model relates to a hydraulic track raising and lining machine used in the raising and lining operation of complete overhaul or medium overhaul of the railway, comprises a frame, a supporting plate, a rail clamping structure, a lifting hydraulic cylinder, a piston rod, a combustion engine, a hand change-over valve, an oil pump, and an oil box, the utility model is characterized in that a supporting shaft which is equipped at two outer sides of the low portion of the lifting hydraulic cylinder is connected movably with the frame achieved. A horizontal display device is equipped on the local mesa to observe whether the rail is in the horizontal position or not. As being connected movably with the frame achieved through the supporting shaft, the lifting hydraulic cylinder can swing around the supporting shaft, and enables the track raising and lining machine can raise as well as line, overcomes the defect which the prior machine can not line.
Description
The utility model relates to a kind of Hydraulic Track Lifting And Lining Machine that is used for the railroad track overhaul or repaiies track lifting and track lining operation.
Existing similar machines can only raise track can not track lining, and the track lining operation still uses the hand-operated tools of manual operation to carry out, inefficiency consequently, and staffing is many.
The purpose of this utility model is in order to overcome the shortcoming of prior art, and a kind of Hydraulic Track Lifting And Lining Machine that can raise track and can track lining is provided.
The technical solution of the utility model is achieved like this, it comprises framework, gripper shoe, folder trailer structure, jacking cylinder, piston rod, internal combustion engine, hand-operated direction valve, oil pump, fuel tank, be characterized in, be equipped with bolster and framework in two outsides, jacking cylinder bottom and realize flexibly connecting.Whether be horizontal in order to observe track, on the table top of this machine, also be equipped with horizontal display unit.
Because jacking cylinder is realized flexibly connecting by bolster and framework, therefore, jacking cylinder can be swung around bolster, this track jack can be raised track and can track lining, has overcome the shortcoming that existing machinery can not track lining.
Embodiment of the present utility model is described further in conjunction with the accompanying drawings.
Fig. 1 is the Hydraulic Track Lifting And Lining Machine structure principle chart.
Embodiment of the present utility model is a combustion power light hydraulic track lifting and lining machine, by shown in Figure 1, it comprises: framework 1, gripper shoe 2, folder trailer structure 3, folder cylinder of rail 4, piston rod 5, jacking cylinder 6, internal combustion engine 7, hand-operated direction valve 8, oil pump 9, fuel tank 10, table top bag 12, be characterized in, be equipped with bolster 11 in two outsides, jacking cylinder 6 bottoms and realize flexibly connecting with framework 1.Whether be horizontal in order to observe track, on the table top 12 of this machine, also be equipped with horizontal display unit 13.Like this, two jacking cylinders of this machine are the straight line hydraulic jacks that center line can be swung, and its oscillation center is the bolster 11 that is in the framework 1, and folder trailer structure 3 is loaded on framework 1 two ends.When jacking cylinder 6 is in when vertical, pressure oil enters jacking cylinder 6 epicoele piston rods and stretches out, and the gripper shoe 2 that install its lower end is depressed roadbed, makes framework 1 drive rail 14 and rises, and finishes the track lifting operation.Then, pull hand-operated direction valve, jacking cylinder 6 cavity of resorption oil-feeds, epicoele oil return, piston rod 5 sets back, and allows jacking cylinder 6 swing to certain angle as after about 30 °, again operation as stated above, framework 1 is pressed incline direction and is risen, and the track lining operation is finished in the displacement of rail 14 occurred level directions.After operation was finished, operation set back piston rod 5 as stated above.Whether be horizontal in order to observe track, on the table top 12 of this machine, also be equipped with horizontal display unit 13.Adopt YANMARL60AE type Diesel engine in the present embodiment, power 4.4KW, the CBF-F410-AL gear pump, rated pressure 20Mpa, rotating speed are 500～3000r/min, flow 10ml/r.The main design parameters of present embodiment: jacking cylinder inside diameter D=110mm, maximum top lift P=175kN, maximum track lifting power N=350kN, maximum track lining power Q=175kN, the range H=700mm of piston.The utility model is compared with existing machinery, increases the track lining function, sets up horizontal display unit, increases top lift, increases the stroke of jacking piston, increases the track lifting amount, and on the make, part adopts light metal, alleviates complete machine weight.
