Description
Technical field
The utility model relates to track lifting devices, more specifically to a kind of track lifting hook applied to hydraulic tool for taking up tracks
Structure.
Background technique
Rail jack is a kind of a kind of small-sized machine used when conserving railway bed.By manual operation, rail jack can
To lift rail, ground certain distance is made it away from, in order to which worker conserves roadbed.It is different according to working principle,
Rail jack can be divided into fluid pressure type and two kinds of rack-and-pinion, and the operating force of hydraulic tool for taking up tracks is smaller, in use such as train
Pass through, can unload and be protected automatically.The great advantage of rack gear rail jack is that speed is fast, and daily maintenance is convenient, therefore at present still
With boundless market.
Hydraulic tool for taking up tracks is suitable for the track of rail main track, and track lifting of turnout junction operation is driven on piston by hand piston pump
It rises, drives track lifting lever, make operation in the track lifting lever front end fast servo of rail foot, reach track lifting operation purpose.It is
Rail track track lifting special tool for service, equal not fouling of clearance gauge when operation are safe and reliable, high-efficient, operation is light, mitigates labour
Intensity.
Track lifting hook on conventional hydraulic rail jack, there are mainly two types of forms: one is rail jack base member and track lifting hooks
Function, act on rail rail bottom, utilize hydraulic coupling be lifted track；Another kind is track lifting hook separately as stress execution unit,
Same purpose is in rail rail bottom.The drawbacks of both forms is embodied in: lifting force acts on rail foot, by operation entirety center of gravity
Lifting, not only bad for site safety, and track lifting hook part will bear biggish unbalance loading, and offset loading force is transmitted to hydraulic piston
When, will cause by the hydraulic execution unit performance that hydraulic cylinder and piston form sharply decline in addition occur it is stuck.
Utility model content
In view of the above defects of the prior art, the purpose of the utility model is to provide one kind to be applied to hydraulic track raising
The track lifting hook structure of device, can symmetrical stress, be not present unbalance loading, structure is more compact, reduce weight, and improve intensity,
Fatigue behaviour.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of track lifting hook structure applied to hydraulic tool for taking up tracks, comprising: track lifting hook ontology；
The front end face setting of the track lifting hook ontology is followed successively by the first overturning under and is kept away in bevelled step-like by upper
It allows inclined-plane, the second overturning to avoid inclined-plane and load inclined-plane, is additionally provided with oil hole on the front end face of track lifting hook ontology；
Oily axis can be led to by being connected on the two sides of the track lifting hook ontology, can be led to and be offered oil duct on axis in oily axis,
In one can lead to oily axis surface equipped with ring shaped oil passage, seal groove is equipped in ring shaped oil passage, oil duct is connected with oil hole on axis；
The track lifting hook is set inside the body spring compartment, logical oily space, annular seal groove and connection screw thread hole, connection
Threaded hole with hydraulic cylinder to be threadedly coupled.
The spring compartment is also communicated with pin hole.
In the above technical solution, a kind of track lifting hook knot applied to hydraulic tool for taking up tracks provided by the utility model
Structure is able to achieve track lifting and is hooked in when being overturn whole process without interference, while compact-sized, reduces weight and improves intensity, fatigability
Can, and symmetrically arranged track lifting is hooked in operation process and no unbalance loading may be implemented, securely and reliably, moreover it is possible to it is narrow to meet working space
Requirement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model track lifting hook structure；
Fig. 2 is the schematic cross-sectional view in Fig. 1 along line A-A；
Fig. 3 is the utility model track lifting hook structure to the state diagram being lifted when rail；
Fig. 4 is state diagram when the utility model track lifting hook structure decontrols rail.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1 to Fig. 4, a kind of track lifting hook knot applied to hydraulic tool for taking up tracks provided by the utility model
Structure, comprising: track lifting hook ontology 1, the track lifting hook ontology 1 have a pair, and the two sides of hydraulic tool for taking up tracks are arranged in mirror symmetry, use
To be lifted to rail 100.
Preferably, the front end face setting of the track lifting hook ontology 1 is in step-like with given bevel, by it is upper under successively
For the first overturning evacuation inclined-plane 2, second overturning evacuation inclined-plane 3 and load inclined-plane 4, load inclined-plane 4 is to the rail jaw with rail 100
It contacts, is additionally provided with oil hole 5 on the front end face of track lifting hook ontology 1.
Preferably, oily axis 6 can be led to by being connected on the two sides of the track lifting hook ontology 1, it can lead in oily axis 6 and offer axis
Upper oil duct 9, one of them can lead to oily 6 surface of axis equipped with ring shaped oil passage 7, and 7 two sides of ring shaped oil passage are equipped with seal groove 8, and axis oils
Road 9 is connected with oil hole 5.
Preferably, the inside of the track lifting hook ontology 1 is equipped with spring compartment 10, logical oily space 11,12 and of annular seal groove
Connection screw thread hole 13, connection screw thread hole 13 with hydraulic cylinder to be threadedly coupled.
Preferably, the spring compartment 10 is also communicated with pin hole 14.
Track lifting hook ontology 1 is connect by the oily axis 6 that leads to of two sides with hydraulic tool for taking up tracks rack section, realizes track lifting hook ontology
1 rotary movement；Track lifting hook ontology 1 can lead to ring shaped oil passage 7, seal groove 8, Yi Jiqi on oily 6 surface of axis by one of them
Internal logical oily space 11, annular seal groove 12, realization and the oil communication between rack section, bottom hydraulic cylinder；Track lifting hook
Ontology 1 is threadedly coupled by connection screw thread hole 13 with hydraulic cylinder, and hydraulic cylinder and track lifting hook ontology 1 are fixed into an entirety.
In conclusion the utility model is to realize overturning whole process without interference, one side operating position needs inclined-plane and rail
Contact, another aspect off-position cannot interfere with rail and prevent rotary movement from cannot achieve, whole design Cheng Te
Fixed step and ramp profile requires compact-sized, reduction weight and raising intensity, fatigue behaviour simultaneously.It is arranged symmetrically in operation
No unbalance loading may be implemented in the process, securely and reliably, overturning structure meets the narrow requirement of working space.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will all be fallen in the Claims scope of the utility model.
