[0034] As Figure 1 - Figure 2 shown, the present invention provides a hydraulic automatic coupler, including: a coupler seat 1, coupler tongs 2, a drive assembly 3 and a link 4;

[0035] Among them, the coupler seat 1 includes a base 12 and a fixed seat 11, and the fixed seat 11 is arranged on the base 12.

[0036] The coupler tongs 2 are rotatably arranged on both sides of the base 12.

[0037] In addition, the drive assembly 3 includes a connector 31, a telescopic hydraulic cylinder 32 and a self-locking hydraulic cylinder 33. The self-locking hydraulic cylinder 33 is arranged on the fixed seat 11, the telescopic hydraulic cylinder 32 is arranged on the base 12, and the connector 31 is arranged on the telescopic piston rod 32.

[0038] One end of the link 4 is arranged on the connector 31, and the other end of the link 4 is rotatably arranged on the coupler tongs 2.

[0039] When the trailer is locked, the piston rod 321 of the telescopic hydraulic cylinder 32 extends to close the two coupler tongs 2, and the self-locking hydraulic cylinder 33 extends and inserts into the connector 31 to lock the coupler, realizing the closed connection of the hydraulic automatic coupler.

[0040] Specifically, the first end of the fixed seat 11 is arranged on the base 12, and the self-locking hydraulic cylinder 33 is arranged at the second end of the fixed seat 11. When the hydraulic automatic coupler is closed, locking can be completed, improving the safety of the hydraulic automatic coupler. The telescopic hydraulic cylinder 32 is arranged on the base 12, and the automatic opening and closing of the hydraulic automatic coupler is realized by using the hydraulic power of the rail-road vehicle, with high efficiency. One end of the connecting rod 4 is arranged on the connecting head 31, and the other end is rotatably arranged on the coupler tongs 2, forming a connecting rod mechanism. The opening and closing of the hydraulic automatic coupler are realized by the extension and retraction of the piston rod 321 of the telescopic hydraulic cylinder 32. When the hydraulic automatic coupler is closed, the self-locking hydraulic cylinder 33 is used to lock the hydraulic automatic coupler, so as to conveniently and safely tow and allocate the mine vehicles.

[0041] Furthermore, the fixed seat 11 is of a plate-like structure. The first end of the fixed seat 11 is arranged on the first side of the base 12, and the second end of the fixed seat 11 is provided with a through hole 121.

[0042] Specifically, the fixed seat 11 is of a plate-like structure, which is convenient for the fixation of the self-locking hydraulic cylinder 33 and the extension of the piston rod 321 to realize the automatic closing of the hydraulic automatic coupler. The second end of the fixed seat 11 is provided with a through hole 121. When the hydraulic automatic coupler extends, the through hole of the connecting head 31 is concentric with the through hole 121 provided at the second end of the fixed seat 11, so that the hydraulic rod 331 of the self-locking hydraulic cylinder 33 can extend, and the self-locking hydraulic cylinder 33 is used to lock the hydraulic automatic coupler, improving the safety of the hydraulic automatic coupler, so as to conveniently and safely tow and allocate the mine vehicles.

[0043] Furthermore, the coupler tongs 2 include a first coupler rod 21, a second coupler rod 22, a first coupler hook 23 and a second coupler hook 24. The first coupler rod 21 and the second coupler rod 22 are respectively rotatably arranged on both sides of the coupler seat 1. The first coupler hook 23 is arranged on the first coupler rod 21, and the second coupler hook 24 is arranged on the second coupler rod 22.

[0044] Specifically, the first coupler rod 21 and the second coupler rod 22 are arranged on both sides of the base 12. The first coupler hook 23 and the second coupler hook 24 are respectively arranged at the second ends of the first coupler rod 21 and the second coupler rod 22. When the hydraulic automatic coupler is closed, the coupler tongs 2 clamp the trailer bar of the vehicle to be towed from both sides, which is convenient for connection and more stable during towing, improving the safety of the hydraulic automatic coupler.

[0045] Furthermore, the first end of the first coupler rod 21 is arranged at the first end of the base 12, the first coupler hook 23 is arranged below the second end of the first coupler rod 21, the first end of the second coupler rod 22 is arranged at the second end of the base 12, and the second coupler hook 24 is arranged above the second end of the second coupler rod 22.

[0046] Specifically, when the hydraulic automatic coupler is closed, the second ends of the first coupler rod 21 and the second coupler rod 22 are closely adjacent to each other, the first clamping hook 23 and the second clamping hook 24 cross each other, the first clamping hook 23 is stuck on one side of the second coupler rod 22, and the second clamping hook 24 is stuck on one side of the first coupler rod 21, so that the coupler clamp 2 is stuck on the trailer rod of the vehicle to be towed, making the connection between the hydraulic automatic coupler and the vehicle to be towed more reliable, not easily decoupled, increasing the safety of the hydraulic automatic coupler, and thus more safely deploying the mine vehicles.

[0047] Furthermore, through holes are provided in the first coupler rod 21 and the second coupler rod 22, and the through holes of the first coupler rod 21 and the second coupler rod 22 are respectively close to the first ends of the first coupler rod 21 and the second coupler rod 22.

[0048] Specifically, through holes are provided in the first coupler rod 21 and the second coupler rod 22, facilitating the connection between the first coupler rod 21 and the second coupler rod 22 and the first connecting rod 41 and the second connecting rod 42 to form a four-bar mechanism. The through holes of the first coupler rod 21 and the second coupler rod 22 are respectively close to the first ends of the first coupler rod 21 and the second coupler rod 22, and there is a relatively large space at the second ends of the first coupler rod 21 and the second coupler rod 22, which will not be blocked by the vehicle to be towed when the hydraulic automatic coupler is closed, so that the hydraulic automatic coupler can be smoothly closed, improving the safety of the hydraulic automatic coupler. The connection between the hydraulic automatic trailer coupler and the vehicle to be towed is more convenient, thus more conveniently and safely deploying the mine vehicles and enhancing the user experience.

[0049] Furthermore, one end of the telescopic hydraulic cylinder 32 is arranged on the base 12, the connecting head 31 is arranged on the piston rod 321 of the telescopic hydraulic cylinder 32, and the self-locking hydraulic cylinder 33 is arranged at one end of the fixed seat 11.

[0050] Specifically, one end of the telescopic hydraulic cylinder 32 is arranged on the base 12. Through the extension and retraction of the piston rod 321 of the telescopic hydraulic cylinder 32, the automatic closing of the hydraulic automatic coupler is realized. The connecting head 31 is arranged on the piston rod 321 of the telescopic hydraulic cylinder 32, and the self-locking hydraulic cylinder 33 is arranged at one end of the fixed seat 11. When the hydraulic automatic coupler is closed, the piston rod 321 of the telescopic hydraulic cylinder 32 extends, and the connecting head 31 is pushed by the piston rod 321 of the telescopic hydraulic cylinder 32 to one end of the fixed seat 11, and the hydraulic rod 331 of the self-locking hydraulic cylinder 33 extends to realize the locking of the hydraulic automatic coupler, improving the safety of the hydraulic automatic coupler, and thus more safely towing and deploying the mine vehicles.

[0051] Furthermore, the telescopic hydraulic cylinder 32 is arranged on the second side of the base 12, and the telescopic hydraulic cylinder 32 is collinear with the fixed seat 11.

[0052] Specifically, the telescopic hydraulic cylinder 32 is collinear with the fixed seat 11. When the piston rod 321 of the telescopic hydraulic cylinder 32 extends, the connector 31 is pushed to the second end of the fixed seat 11, and the through hole 121 of the fixed seat 11 is concentric with the through hole of the connector 31, which is convenient for the self-locking hydraulic cylinder 33 to lock the hydraulic automatic coupler, improving the safety of the hydraulic automatic coupler. When the connector 31 is pushed, the linkage mechanism is driven, and the hydraulic automatic coupler is automatically closed, realizing simple connection and high efficiency, so as to quickly, conveniently and safely allocate the mine vehicles.

[0053] Furthermore, the self-locking hydraulic cylinder 33 is arranged below the second end of the fixed seat 11. The connector 31 is provided with a through hole, and the hydraulic rod 331 of the self-locking hydraulic cylinder 33 is concentric with the through hole 121 of the fixed seat 11.

[0054] Specifically, when the connector 31 is pushed to the second end of the fixed seat 11, the self-locking hydraulic cylinder 33 releases hydraulic oil, and the hydraulic rod 331 extends under the action of spring force, passes through the through holes of the fixed seat 11 and the connector 31, and locks the hydraulic automatic coupler. When the hydraulic rod 331 of the self-locking hydraulic cylinder 33 extends, the self-locking hydraulic cylinder 33 completes self-locking, making the hydraulic automatic coupler unable to disconnect, so as to ensure the complete closure of the hydraulic automatic coupler and improve the safety of the hydraulic automatic coupler. When the piston rod 321 of the telescopic hydraulic cylinder retracts, the hydraulic rod 331 of the self-locking hydraulic cylinder 33 retracts under the action of hydraulic force, completing the opening of the hydraulic automatic coupler, realizing simple connection and automatic closure of the hydraulic automatic coupler, and improving the efficiency.

[0055] Furthermore, the connecting rod 4 includes a first connecting rod 41 and a second connecting rod 42. The first ends of the first connecting rod 41 and the second connecting rod 42 are respectively arranged on the through holes of the first coupler rod 21 and the second coupler rod 22. The connector 31 is provided with a blind hole, and the second ends of the first connecting rod 41 and the second connecting rod 42 are jointly arranged on the blind hole of the connector 31.

[0056] Specifically, the first connecting rod 41, the first coupler rod 21 and the telescopic hydraulic cylinder 32 form a first four-bar mechanism, and the second connecting rod 42, the second coupler rod 22 and the telescopic hydraulic cylinder 32 form a second four-bar mechanism. The second ends of the first connecting rod 41 and the second connecting rod 42 are jointly arranged on the blind hole of the connector 31. When the piston rod of the telescopic hydraulic cylinder 32 extends, it drives the first connecting rod 41 and the second connecting rod 42 to move, thus completing the automatic opening and closing of the hydraulic automatic coupler, improving the efficiency, and thus conveniently and safely towing and allocating the mine vehicles.

[0057] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
