Description
Technical field
Present patent application belongs to railway locomotive repair apparatus technical field, specifically a kind of fast assembling-disassembling railway locomotive axle box
Lifting device.
Background technique
Railway locomotive axle box is the base frame of the installation positioning of axle bearing, is to transmit locomotive in locomotive running gear system to lead
Gravitation and brake force play installation axlebox rod, installation axle box spring shock absorption, the important component for positioning the traversing limit of axle, need
Periodically carry out the work such as overhaul, measurement, replacement bearing.Open and inspect, replace locomotive axle box be an operating procedure it is more, work
Measure a biggish service work；As shown in Fig. 2 (axle box schematic view of the mounting position), because being limited and locomotive by bogie frame body
Body limp block cannot direct vertical lifting, axle box assembly is heavier, can not directly move by manpower.Because car body gravity passes through
Journal box spring reaches motorcycle axle, according to original maintenance craft step, locomotive car body is needed to erect, and releases bogie and decomposes
Axle box maintenance is dismantled after train wheel again, maintenance need to also reassemble after more finishing changing axle box, bearing according to reverse procedure, therefore cause machine
It is long between the garage stopping time, locomotive operation is influenced, maintenance workload is larger, dismounts relatively difficult.
To improve locomotive inspection and repair efficiency, the cost of overhaul is saved, reduces worker's labor intensity, it is necessary to make a set of Special-purpose hanger
Holding tool decomposes replacement maintenance craft to original axle box and improves.Quick-replaceable railway locomotive axle box special tooling is set
Meter thinking is not have to unwheeling and decompose bogie, can directly split out axle box using hoisting tool special and carry out at maintenance replacement
Reason.
Utility model content
The utility model technical issues that need to address are to provide a kind of lifting device of fast assembling-disassembling railway locomotive axle box,
The dismounting process step that axle box can be simplified reduces the labor intensity of worker, improves locomotive inspection and repair efficiency, shortens the library stopping time of locomotive
Between.
To solve the above-mentioned problems, the technical scheme adopted by the utility model is
A kind of lifting device of fast assembling-disassembling railway locomotive axle box exists including sunpender, the hanging ring being fixed on sunpender, setting
The annular boom tip cooperated with the insertion of axle box hanging ring of sunpender one end is anti-to be disengaged from the groove, and annular boom tip is anti-to be disengaged from the groove including sequentially connected
Vertical portion, horizontal part and tapered portion, vertical portion and sunpender equal diameter, the diameter of horizontal part and the internal diameter of axle box hanging ring cooperate and small
In the diameter of sunpender, tapered portion is connect with sunpender.
Technical solutions of the utility model further improvement lies in that: hanging ring be positioned close to annular boom tip it is anti-be disengaged from the groove hang
The side of bar.
Technical solutions of the utility model further improvement lies in that: the diameter of horizontal part be sunpender diameter 1/2-2/3.
Technical solutions of the utility model further improvement lies in that: the angle that tapered portion and horizontal plane are in is 20-45 °.
Technical solutions of the utility model further improvement lies in that: tapered portion and sunpender junction are smoothed by circular arc
It crosses.
By adopting the above-described technical solution, the beneficial effect that the utility model obtains is: present apparatus structure is simple, uses
It is convenient, dismounting axle box is carried out without unwheeling using the utility model and decomposes bogie, need to only remove the spring of axle box, pull rod and
End cap, it is the fast assembling-disassembling that the utility model can be used to carry out axle box that bogie frame body is slightly jacked up with jack, is greatly simplified
The dismounting process step of axle box, reduces the labor intensity of worker, greatly improves locomotive inspection and repair efficiency, shorten the library of locomotive
Between stopping time.
