[0030] The main body of the James coupler consists of two sets of hook seats that engage and pull each other, and are connected to the train carriage or locomotive respectively. Each set of hook seats includes three parts: the hook head, the hook body and the hook tail. The hook head part usually consists of three parts: the hook tongue, the hook tongue pin and the hook lock. Embodiment 1
[0031] Combination Figures 1 to 5 As shown, a Zhan-type vehicle coupler coupling auxiliary device comprises an upper mounting seat 11, in which a hook tongue 2 opening mechanism and a hook head 1 straightening mechanism are provided. The hook tongue 2 opening mechanism is arranged at the front of the mounting seat 11, and a cantilever frame 30 is arranged at one side of the front of the mounting seat 11, and a lever 3 is hingedly connected at one end of the cantilever frame 30 away from the mounting seat 11, and a pin 31 is vertically penetrated in the lever 3, and a swing mechanism is arranged at one side of the lever 3. The swing mechanism comprises a driving arm 4, and a vertically arranged lever post 41 is arranged at one end of the driving arm 4, and the other end of the driving arm 4 is connected to a rotary driving box 7, and the outer wall of the lever post 41 is in sliding contact with one side of the lever 3.
[0032] Combination Figure 2 As shown, the rotary drive box 7 includes a shell 70 and a motor 711. The shell 70 is arranged at the bottom of the mounting base 11.

[0033] When using, combine Figures 1 to 4 As shown, the mounting base 11 is connected to the lower side of the James type coupler, the pin rod 31 is inserted into the hook tongue 2 of the James type coupler and is rotatably connected to each other. When the James type coupler needs to be docked, the motor 711 drives the first driving wheel 71 in the rotating driving box 7 and the second driving wheel 72 meshing therewith to rotate, and the second driving wheel 72 drives the driving arm 4 to swing. Since the shifting column 41 is slidably connected to one side of the shifting rod 3, the shifting rod 3 is swung outward, and finally the hook tongue 2 is opened outward, eliminating the trouble of manually opening the hook tongue 2 and improving the level of automation.
[0034] Combination Figure 3 As shown, since the upper rear end of the hook head 1 of the James type coupler is usually penetrated with a latch 8, the latch 8 is penetrated between the hook head 1 and the hook tongue 2, and the top of the latch 8 is connected with a lifting mechanism 9. The lifting mechanism 9 includes a cantilever rod 91 and a shaft rod 92, the shaft rod 92 is horizontally arranged, one end of the cantilever rod 91 is vertically connected to the middle of the shaft rod 92, and the other end of the cantilever rod 91 is connected to the top of the latch 8 through a chain 93, the shaft rod 92 is rotatably connected to a fixed seat 101, and the fixed seat 101 is fixed to the front of the vehicle body 10, and a hinged arm 94 is fixed to one side of the cantilever rod 91, and one end of the hinged arm 94 away from the shaft rod 92 is hinged to one end of a telescopic mechanism 95, and the other end of the telescopic mechanism 95 is hinged to the front of the vehicle body 10, and the telescopic mechanism 95 can be driven in a variety of ways such as hydraulic, pneumatic or linear motor.
[0035] Before a pair of couplers of the James-type coupler are connected, it is necessary to ensure that the latch pin 8 is in an open state of being pulled upward, and only then can the hook tongue 2 be unlocked and rotated outward. Since a telescopic mechanism 95 is provided, when the telescopic mechanism 95 is extended upward, the shaft rod 92 can be driven to drive the cantilever rod 91 to rotate upward, and then the latch pin 8 can be pulled out upward, thereby realizing automatic unlocking of the hook tongue 2 and the hook head 1.
[0036] Combination Figure 1 and Figure 5 As shown, a placement cavity 110 is provided at the top of the mounting seat 11, a rear baffle wall 111 is provided at the rear side of the placement cavity 110, a front baffle wall 112 is provided at the bottom of the placement cavity 110, a connecting block 12 is passed through the rear baffle wall 111 and the front baffle wall 112, the connecting block 12 is arranged at the bottom of the James-type coupler, a position locking mechanism is provided between the placement cavity 110 and the connecting block 12, the position locking mechanism is a bayonet 113, the bayonet 113 is transversely passed through the side where the rear baffle wall 111 and the placement cavity 110 are connected, a notch is provided on the side where the connecting block 12 and the rear baffle wall 111 are connected, and the bayonet 113 is passed through the notch.
[0037] The auxiliary device for coupling the Zhan-type coupler is connected to the existing Zhan-type coupler through a mounting seat 11. A connecting block 12 is usually provided at the bottom of the existing Zhan-type coupler. During installation, the connecting block 12 is inserted into the placement cavity 110. The front and rear surfaces of the connecting block 12 are respectively in contact with the rear baffle wall 111 and the front baffle wall 112. When the notch in the connecting block 12 is aligned with the setting position of the bayonet 113, the bayonet 113 is inserted to lock the position of the mounting seat 11. Through holes are provided at both ends of the bayonet 113, and cotter pins can be inserted into the through holes at both ends of the bayonet 113 to prevent the bayonet 113 from accidentally slipping out. Embodiment 2
[0038] The rear end of the James coupler is hinged to the vehicle body 10, and the Figures 1 to 3 As shown, a further hook head 1 straightening mechanism in a Zhan-type coupler coupling auxiliary device includes a first straightening arm 51 and a second straightening arm 52, and the left and right sides of the bottom of the rotating drive box 7 are respectively provided with a horizontally rotating first straightening arm 51 and a second straightening arm 52, and the outer sides of the first straightening arm 51 and the second straightening arm 52 are respectively provided with a limiting arm 6, the bottom of the first driving wheel 71 is connected to the first straightening arm 51, and the bottom of the fourth driving wheel 74 is connected to the second righting arm 52, the first righting arm 51 and the second righting arm 52 are arranged in mirror symmetry, and one end of the first righting arm 51 and the second righting arm 52 are respectively in sliding contact with the relative inner sides of the two limiting arms 6.

[0040] When in use, the end of the limit arm 6 is fixed to the vehicle body 10, and the motor 711 drives the first drive wheel 71 to rotate. Since the rotation directions of the first drive wheel 71 and the fourth drive wheel 74 are opposite, the first righting arm 51 and the second righting arm 52 can be swung in a mirror image. When the first righting arm 51 and the second righting arm 52 are rotated from an inward-retracted state to an outward-expanded state at one end away from the rotating drive box 7, the fixed limit arm 6 can be used to center and right the hook head 1, which provides favorable conditions for the connection of the James type coupler and avoids manual intervention. Since the hook head 1 righting mechanism and the hook tongue 2 opening mechanism share a rotating drive box 7, the coordinated linkage of the two actions can be achieved, simplifying the mechanism and saving control and maintenance costs.
[0041] The control method of the present invention is automatic control through a controller.
