Hook is mainly to be applicable in as principle, and not yet formulation relevant design standard, each enterprise are different to the design form of hitch.
Transition car coupler is subjected to biggish shock loading in distraction procedure, in order to keep intensity up to standard, the knot of transition car coupler
Configuration formula is mostly thick and heavy plate construction, and construction weight is larger, so that it is more painstaking in disassembly process in transition car coupler, it is hung in nothing
Installing the lower of standby situation needs 3-5 people's operation simultaneously, labor intensive；In addition, generally set hitch position to can for transition car coupler
Rotational structure, to adapt to the requirement of different model locomotive, this structure type has transition car coupler in the operating condition
Due to shaking and impacting the risk for causing hitch and tractor to be detached from, there are security risks, threaten engineer's health and wealth
Produce safety.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides the utility model and provides a kind of novel transition
Hitch can effectively improve the lightweight and security requirement of transition car coupler.
The technical scheme adopted by the utility model is a kind of novel transition hitch, including connection component and hitch, it is described
Connection component is connected with carriage connecting device；The connection component includes couple yoke, coupler yoke key and several connecting pin bores, described
Coupler yoke key is fixedly mounted on couple yoke upper surface middle part, and the connecting pin bores is fixedly mounted on couple yoke lower surface, and parallel
It is arranged as two rows；The hitch includes gib head and hook body, and hook body bottom end is equipped with vertical flat lockhole, the connection component and vehicle
Hook is connected by Type B pin shaft, is additionally provided with fiber gasket between the coupler yoke key and vertical flat lockhole；The hitch further includes delaying
The limit card board of screw and fixed installation at an upper portion thereof is rushed, the hitch opening outwardly protrudes to form connected unit, the buffering
Screw is bolted with connected unit, and the buffer screw is cylindrical body, the limit card board and gib head tight closure, is formed
Close ring.
Further, the limit card board is cuboid, and the bond length of limit card board is than the diameter of buffer screw
Long 10-15mm.
Further, the buffer screw is rubber material.
Further, the coupler yoke key is cuboid, and the cuboid two sides are additionally provided with the connector to be bonded.
Further, the connector shape be right angled triangle, the right-angle side of the connector respectively with coupler yoke key and
Couple yoke is in contact.
Compared with prior art, the utility model has the beneficial effects that
1, increase cylindrical rubber buffer screw and limit card board at hitch rear portion, can prevent in distraction procedure because of connection structure
The concussion that is hit causes tractor and transition car coupler to be detached from and cause safety accident.
2, the connection component of transition car coupler and hitch part are directly connected to using Type B pin shaft, hitch part can be around Type B pin
Axis rotation, hitch, which is rotated upwardly and downwardly, is adjusted fixation to the angle of hitch using adjustment gasket and fastening bolt, can be in very great Cheng
Mitigate transition car coupler overall weight on degree.
3, when tractor is connect with locomotive, this novel hitch lighter in weight, engineer can voluntarily carry out tractor and machine
The connection of vehicle, reach distracted position after also can realizing self disassembling.
