[detailed description of the invention]
Explain the specific embodiment of the present invention with reference to the accompanying drawings.These explanations are only descriptive, exemplary.
Fig. 2 is the schematic perspective view of the detailed description of the invention according to hydraulic tool for taking up tracks of the present invention.As shown in FIG., this hydraulic tool for taking up tracks 100 mainly comprises the parts such as pedestal 110, hand piston pump (see Fig. 3) 120, hydraulic cylinder 130, track lifting hook 140 and handle 150 (see Fig. 2).Pedestal 110 be whole rail jack basic part, and parts such as hydraulic cylinder 130 grade are arranged on pedestal 110.
As can be seen from the figure, hydraulic cylinder 130 is vertically arranged on pedestal 110, is preferably at middle part, ensure that track lifting power is upwards all the time.Liquid in hydraulic cylinder 130 is preferably hydraulic oil, and it is contacted by hydraulic circuit and hand piston pump 120, and when operating the hand 160 by the emperor himself of hand piston pump 120, the piston 170 of hydraulic cylinder 130 produces motion upwards.In addition, the pressure-relief valve (see Fig. 3) 180 in hydraulic system can play the effect to hydraulic cylinder 130 release.In rail jack, using hydraulic system also ensure that, the operation controllability of rail jack is strong, working stability.About the specific works principle of hydraulic system, be no longer explained in detail in the present invention.
Hydraulic tool for taking up tracks 100 has two track lifting hooks 140, preferably L-shaped, the hook portion 142 that each track lifting hook 140 includes vertical arm 141 and stretches out forward in vertical arm 141 lower end.These two track lifting hooks 140 are set up on the piston 170 of hydraulic cylinder 130 by crossbeam 190, and the vertical arm 141 of two track lifting hooks 140 is symmetrically located at the both sides of hydraulic cylinder 130.Although two track lifting hooks 140 and crossbeam 190 are for split-type design is then combined together and formed in the present embodiment, in the embodiment that other is concrete, they also can be arranged integratedly.Illustrated preferred embodiment in, distance between the hook portion 142 of track lifting hook 140 is greater than the width of corresponding position base 110, thus when piston 170 drops to extreme lower position, hook portion 142 can be positioned at the both sides of base 110, not by the restriction of the thickness of pedestal 110 on vertical position.In preferred embodiment, the thickness of the part that pedestal 110 is clipped between hook portion 142 is less than or equal to the thickness of hook portion 142, then further ensure that, the thickness of pedestal 110 can have influence on the working range of rail jack in no instance, makes the thickness of hook portion 142 determine the minimum altitude of raising track uniquely.
The opposition side being positioned at hook portion 142 is respectively arranged with antifriction plate on vertical arm 141 top of track lifting hook 140 and on the side being positioned at hook portion 142 and in vertical arm 141 bottom of track lifting hook 140.Can understand, when track lifting hook 140 is in running order, the pressure due to track can produce distortion and depart from vertical position, to produce and rubs, affect stability and the application life of work at above-mentioned two positions and pedestal 110 to its support zone.By arranging two blocks of antifriction plates, effectively improve this situation.
As shown in the figure, handle 150 is arranged on the top of rail jack, and preferably can be movable.Inherently structure is simple, quality light for the hydraulic tool for taking up tracks provided due to this invention, and by the setting of this handle 150, product is easy to carry about with one especially, is suitable for the flexible use in the situations such as rail maintenance.In alternative embodiments, can also give handle 5 load onto suitable material, shape sheath to increase comfortableness.
Fig. 3 is another schematic perspective view of the detailed description of the invention according to hydraulic tool for taking up tracks 100 of the present invention, illustrated therein is hand piston pump 120, and it is positioned on the side contrary with hook portion 142, and is provided with hand 160 by the emperor himself.The position of rail on hydraulic tool for taking up tracks 100 when dotted line in figure schematically shows track lifting, it is very near hydraulic cylinder 130 and piston 170 as seen, compared with prior art greatly reduces the moment of torsion applied track lifting hook.
Known by as above illustrating, when carrying out track lifting operation, the hook portion 142 of hook 140 that hydraulic tool for taking up tracks 100 raises track only need reach under the track of rail by operating personnel, then the hand 160 of admiring of reciprocal down operation hand piston pump 120, hydraulic tool for taking up tracks 100 just raises the piston 170 of hydraulic cylinder 130 inside by inner hydraulic system, and then, piston 170 promote track lifting hook 140 crossbeam 190, impel track lifting hook 140 to raise track.After the work such as maintenance of railroad track completes, can pass through pressure-relief valve 180 removal hydraulic pressure, piston 170 declines, and is then moved apart by hydraulic tool for taking up tracks 100.
As mentioned above, with reference to accompanying drawing, exemplary embodiments of the present invention has been described in detail.Should understand, the application is also not intended to make these details to form limiting the scope of the invention.When not deviating from according to the spirit and scope of the present invention, can carry out equivalent or similar change to the structure of exemplary embodiments and feature, these changes will also drop in the determined protection domain of appending claims of the present invention.
