Abstract
The invention provides a split type hydraulic track jack. The split type hydraulic track jack comprises a handle, a jacking hook device, a jacking oil cylinder device, a guide post, reset springs, spring protective bushes, an oil pipe joint and a base; the jacking oil cylinder device is installed on the base; the upper end of the jacking oil cylinder device is provided with the jacking hook device; the handle is arranged on the jacking hook device; the interior of the jacking oil cylinder device is provided with the guide post; bilateral sides of the jacking oil cylinder device are provided with the spring protective bushes; the reset springs are installed inside the spring protective bushes; the oil pipe joint is installed on the jacking oil cylinder device. The split type hydraulic track jack has the advantages of being simple in structure, long in service life, convenient and time and energy saving to operate and can be far from a track jack when being used and safely and conveniently execute track jack operation on a track.
Description
Technical field
The present invention relates to hydraulic tool field, be specially a kind of Split type hydraulic track jack.
Background technology
To the hydraulic track jack of rail track lifting operation in prior art, one is a kind of monolithic construction, comprise: oil pump, oil cylinder, fuel tank, track lifting hook, another kind of track lifting hook adopts screw thread and oil cylinder to link together, make oil cylinder up when oil pump action thus drive track lifting hook to rise (this oil cylinder installation form stands upside down), playing top dog and need decline when resetting and will rely on External Force Acting.There is following shortcoming, one in the track jack of this structure: body volume is large, heavy, operation inconvenience, and particularly operating personnel's distance track jack is excessively near, poor stability; Its two: with being threaded between track jack with steel cylinder, the operation of the hook that in addition raises track is one-sided lateral forces, therefore junction easily produces degenerative lesion.
Summary of the invention
Technical problem solved by the invention is to provide a kind of Split type hydraulic track jack, to solve the problem proposed in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions: Split type hydraulic track jack, comprise: handle, top lifting hook device, top lifting cylinder apparatus, lead, back-moving spring, spring protecting sleeve, oil connection, base, described top lifting cylinder apparatus is arranged on base, top lifting cylinder apparatus upper end is provided with top lifting hook device, top lifting hook device is provided with handle, top lifting cylinder apparatus inside is provided with lead, top lifting cylinder apparatus both sides are provided with spring protecting sleeve, in spring protecting sleeve, back-moving spring is installed, top lifting cylinder apparatus is provided with oil connection.
Described top lifting hook device is set in the piston rod part of top lifting cylinder apparatus.
Described base, top lifting cylinder apparatus are provided with fastening devices.
Compared with prior art, the invention has the beneficial effects as follows: structure of the present invention is simple, long service life is easy to operate time saving and energy saving, away from track jack, safely and conveniently can implement track lifting operation to rail when the present invention uses in addition.

Detailed description of the invention
In order to make actualizing technology means of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention further.
As shown in Figures 1 to 3, Split type hydraulic track jack, comprise: handle 1, top lifting hook device 2, top lifting cylinder apparatus 3, lead 4, back-moving spring 5, spring protecting sleeve 6, oil connection 7, base 8, described top lifting cylinder apparatus 3 is arranged on base 8, top lifting cylinder apparatus 3 upper end is provided with top lifting hook device 2, top lifting hook device 2 is provided with handle 1, top lifting cylinder apparatus 3 inside is provided with lead 4, top lifting cylinder apparatus 3 both sides are provided with spring protecting sleeve 6, back-moving spring 5 is installed in spring protecting sleeve 6, top lifting cylinder apparatus 3 is provided with oil connection 7.
Described top lifting hook device 2 is set in the piston rod part of top lifting cylinder apparatus 3.
Described base 8, top lifting cylinder apparatus 3 are provided with fastening devices, fixing for installing.
Oil pump connects with the oil connection 7 on top lifting cylinder apparatus 3, is separated.
The top lifting hook device 2 of described track jack is set in the piston rod part of top lifting cylinder apparatus 3.
Described top lifting cylinder apparatus 3 is vertical type, and during 3 operation of top lifting cylinder apparatus, piston rod rises, thus the jack-up top lifting hook device 2 on straight top.
Described back-moving spring 5, when declining without External Force Acting for resetting at top lifting hook device 2, is resetted by back-moving spring 5 pulling force.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
