Description
Technical field
The invention belongs to hitch switching device fields, and in particular to a kind of shunter anticreep hitch switching device and vehicle
Hook anti-dropout control method.
Background technique
Shunter refers to for train marshalling list, the locomotive for disintegrating, turning the shunting services such as line and vehicle taking sending.Work characteristics
It is continually to start and stop.
Shunter is the basic motive of work of shunting, and is technically required with the train locomotive of general tractor-trailer train
It is different.Since needs start traction or push vehicle group in short distance, therefore higher desin speed is not needed, but need centainly
Tractive force, due to need often move forward or back, therefore require have it is good watch from a height or a distance condition, due to mainly stand in operation, need
By the curve of small radii, therefore the inflexible wheel base of locomotive is required to want small, due to being frequently necessary to starting and stopping vehicle.Therefore locomotive is required to grasp
It is vertical that flexibly braking ability is good, due to often in night work, lamp lighting requirement good brightness end to end；Furthermore it is required that convenient adjust
Vehicle personnel safety is got on or off the bus etc..
But in the hitch switching device (such as patent CN201320400870.9) on existing shunter in connection
The connection being easy to appear between hitch and hitch rotating device loosens, and the problem of falling off, there are great security risks.

Structure (124) includes first gear (1241), second gear (1242), horizontal sawtooth bar (1243) and connecting bracket (1244), and
One gear (1241), second gear (1242) and horizontal sawtooth bar (1243) successively engage, lifting saw teeth bars (1206) and first
Gear (1241) engagement, connecting bracket (1244) include the cross bar and vertical bar in T-shaped connection, vertical bar and fixing shell
(123) it is fixedly connected, horizontal sawtooth bar (1243) connect with cross bar and can move along cross bar direction, and horizontal sawtooth bar (1243)
It is perpendicular with the direction of motion of lifting saw teeth bars (1206)；Horizontal sawtooth bar is also provided with horizontal concrete chute, horizontal concrete chute on (1243)
Buckle is inside installed, movable contact (1223) and is snapped connection and can be with buckle transversely sliding slot sliding.
6. shunter according to claim 5 anticreep hitch switching device, it is characterised in that: the power supply connecting box
(125) include close button (1251), power supply box main body (1257) and slided set on power supply box main body (1257) internal switch
Button (1253), the second connecting spring (1254), switch slot (1255), close button (1251) are set on fixing shell (123), open
Pass slider (1253) is set in switch slot (1255), the two passes through the second connecting spring (1254) and connects, and is switched slider (1253)
Connect by connection vertical bar (1252) with close button (1251), the output port of power source (1256) of power supply box main body (1257) and
The movable contact (1223) of power supply connecting mechanism (122) connects.
7. shunter according to claim 6 anticreep hitch switching device, which is characterized in that the anti-dropout of the device
Control method are as follows:
Hitch connection locking: powering on, and trunnion (4) insertion at connecting plate (3) both ends is connected to and snaps actuating mechanism (120)
Position-limited box (1202) in, trunnion (4) makes to connect magnetic patch (1201) to be gone towards internal direction pressure, and is transferred on gag lever post (1204)
Parallel cross bar (1205) falls, and connection magnetic patch (1201) drives lifting saw teeth bars (1206) mobile towards lower section, goes up and down saw teeth bars
(1206) movement drives horizontal sawtooth bar (1243) edge after first gear (1241) and second gear (1242) engagement output
Connecting bracket (1244) cross bar it is mobile towards left direction, horizontal sawtooth bar (1243) drive movable contact (1223) towards
Left direction is moved to fit closely face-to-face with fixed contact (1222) and connect；The internal electricity of power supply box main body (1257) at this time
Source passes through output port of power source (1256), movable contact (1223), fixed contact (1222), conduction to plant-grid connection block (1217)
Inside, then electromagnetic coil (1216), which is powered, generates electromagnetic field, and connection magnetic patch (1201) and trunnion (4) are tightly attracted and locked,
Realize the anti-deprotection to hitch；
Hitch is detached from: being pressed close button (1251), is pushed away under the connection vertical bar (1252) connecting with close button (1251), and will
It switchs slider (1251) to glide along switch slot (1255), since switch slider (1253) and power supply box main body (1257) are internal tight
Close connection, then power supply box main body (1257) internal electric source cutting is closed, internal without power input to electromagnetic coil (1216),
Then electromagnetic field effect disappears, and can easily separate trunnion (4) and position-limited box (1202), and hitch is made to be detached from adapter frame.
