When the traction plate frame 1 and the latch 2122 frame 2 meet certain conditions, they can be automatically connected without manual operation, thereby realizing the connection between the first material vehicle and the second material vehicle. When another condition is met, the traction plate frame 1 and the latch 2122 frame 2 can be automatically separated, thereby realizing the separation of the first material vehicle and the second material vehicle.

[0027] As an optional embodiment, the first traction member 11 includes a first limiting member 111 and a first connecting hole 112, wherein the first connecting hole 112 is located on a side of the first traction member 11 away from the first fixing member 12, and the first limiting member 111 is located on a side of the first connecting hole 112 close to the first fixing member 12.

[0028] Specifically, the first limiter 111 is provided with a first sensing member, which can send a command to the rear vehicle to stop the vehicle when the two vehicles need to be connected and sense that the two vehicles have been connected, and send a command to the rear vehicle to restore the anti-collision function when the two vehicles need to be separated. The first connection hole 112 and the second connection hole 215 have the same aperture. When the other end of the first traction member 11 contacts the second limiter 213, the first connection hole 112 and the second connection hole 215 are coaxial.

[0029] As an optional embodiment, the first fixing member 12 includes a first fixing end 121 and a second fixing end 122, the first fixing end 121 is connected to the first traction member 11 to form an L-shaped structure with the first traction member 11, the second fixing end 122 is parallel to the first fixing end 121, the first fixing end 121 is provided with a plurality of first through holes 1211, and the second fixing end 122 is provided with a plurality of second through holes 1221 matching the first through holes 1211.

[0032] Specifically, the first reinforcing frame 13 forms a triangular support structure with the first pulling member 11 and the first fixing member 12. As a preferred embodiment, the first pulling member 11 and the first fixing member 12 are perpendicular to each other.

[0033] As an optional embodiment, the second traction member 21 includes a mounting frame 211, and an automatic telescopic member 212 and a second limiting member 213 arranged on the mounting frame 211. The second limiting member 213 is provided with an automatic sensing member 214, and the automatic sensing member 214 can sense the contact state between the second limiting member 213 and the first traction member. The automatic telescopic member 212 can perform telescopic movement according to the contact state between the second limiting member 213 and the first traction member, thereby controlling the connection and disconnection between the first traction member and the second traction member 21.

[0034] Specifically, when the material vehicle equipped with the traction plug frame is connected to the front vehicle, the second limiting device can make the first connection hole 112 on the first traction member 11 coaxial with the second connection hole 215 on the second traction member 21, so as to facilitate the bolt 2122 to pass through the first connection hole 112 and realize the connection between the front and rear vehicles.

[0035] As an optional embodiment, the automatic telescopic member 212 includes a DC motor push rod 2121, and a pin 2122 arranged at one end of the DC motor push rod 2121, the other end of the DC motor push rod 2121 is arranged on the mounting frame 211, and the mounting frame 211 is also provided with a second connecting hole 215, the second connecting hole 215 matches the position of the DC motor push rod 2121, and can accommodate the extended pin 2122.

[0036] Specifically, the position matching between the second connection hole 215 and the DC motor push rod 2121 means that the second connection hole 215 is coaxial with the DC motor push rod 2121. The latch 2122 is also coaxial with the DC motor push rod 2121.

[0037] As an optional implementation, the second limiting member 213 is disposed on a side of the second connecting hole 215 close to the second fixing member 22 , and is used to limit the movement of the first traction member 11 .

[0038] Specifically, when the front vehicle stops at the designed position, the rear vehicle moves automatically, and the front end of the first traction member 11 installed at the head of the rear vehicle coincides with the rear end of the second traction member 21 installed at the rear of the front vehicle. The front end of the first traction member 11 contacts the second limit member 213, and cannot continue to move forward under the restriction of the second limit member 213, and triggers the automatic sensing member 214 installed on the second limit member 213. The automatic sensing member 214 sends an instruction to the automatic telescopic member 212, and the DC motor push rod 2121 rotates forward to push the latch 2122 upward, and is successively inserted into the second connecting hole 215 and the first connecting hole 112. After the upward movement is completed, the automatic sensing member 214 senses the induction switch on the first limit member 111 installed on the first traction member 11, and sends a completion instruction for the latch 2122, and the DC motor push rod 2121 stops, thereby realizing the automatic connection between the two vehicles. When two connected material carts need to be separated, the two connected material carts stop at the designed position, which sends a disengagement command to the front car, and the DC motor push rod 2121 reverses, driving the latch 2122 downward. When the DC motor push rod 2121 moves down to the right position, the front car sends a forward command, and the induction switch set on the second limiter 213 loses induction, realizing the separation of the two cars. At the same time, the induction switch installed on the first limiter 111 of the rear car loses induction, and sends a disengagement condition, and the rear car resumes the anti-collision function. The two carts are automatically separated, and will not be connected before walking to the designed connection position, and they will always control their own walking.

[0039] As an optional embodiment, the mounting frame 211 is two plate-like structures arranged in parallel, and a second reinforcing frame 216 is provided in the middle of the mounting frame 211. The two ends of the second reinforcing frame 216 are respectively connected to the two plate-like structures for strengthening the bearing capacity of the latch 2122 frame 2.

[0040] Specifically, the middle portion of the mounting frame 211 refers to the middle portion of two parallel plate-like structures. As a preferred embodiment, the second reinforcing frame 216 is arranged in parallel with the third fixing end 221 .

[0041] As an optional embodiment, the second fixing member 22 includes a third fixing end 221 and a fourth fixing end 222. The second fixing end 122 is connected to the second traction member 21 to form a U-shaped structure with the second traction member 21. The third fixing end 221 is parallel to the fourth fixing end 222. The third fixing end 221 is provided with a plurality of third through holes 2211, and the fourth fixing end 222 is provided with a plurality of fourth through holes 2221 matching the third through holes 2211.

[0042] Specifically, the third fixed end 221 can be installed on the outer side of the rear frame beam of the material cart, and the fourth fixed end 222 can be installed on the inner side of the rear frame beam of the material cart. The third fixed end 221 can be connected to the fourth fixed end 222 by screws to fix the second traction member 21 on the material cart.

[0043] As an optional embodiment, the first fixed end 121 is provided with a first positioning end 1212, and the second fixed end 122 is provided with a second positioning end 1222 opposite thereto, and the first positioning end 1212 cooperates with the second positioning end 1222 to achieve precise positioning of the first fixing member 12; the third fixed end 221 is provided with a third positioning end 2212, and the fourth fixed end 222 is provided with a fourth positioning end 2222 opposite thereto, and the third positioning end 2212 cooperates with the fourth positioning end 2222 to achieve precise positioning of the second fixing member 22.

[0044] Specifically, the positioning end is a convex block, and the first fixed end 121 and the second fixed end 122 are positioned in the height direction by the first positioning end 1212 and the second positioning end 1222 corresponding to the position thereof. The positioning method of the third fixed end 221 and the fourth fixed end 222 is the same as the above method. The use of convex blocks can realize the rapid positioning, installation and fixation of the latch 2122 frame 2 and the traction plug plate frame 1. By adopting the above technical scheme, a latch frame is set at the rear of the front material car, and a matching traction plug plate frame is set at the head of the rear material car, so that the front material car can pull the rear material car. When the two cars are to be connected, the latch frame can sense the contact of the traction plug plate frame of the rear material car. When it is sensed that the traction plug plate frame contacts the second limiter on the latch frame, the DC motor push rod automatically latches upward and is inserted into the latch hole at the front end of the traction plug plate frame to realize the automatic connection of the two cars. When the two vehicles are to be separated, the latch rack can receive the disengagement instruction, the DC motor push rod reverses, drives the clutch latch downward, and the latch is disengaged from the latch hole at the front end of the traction plate rack, realizing the separation of the two vehicles. The connection and separation of the two material vehicles can be automatically realized without manual control, which is simple to operate, high-speed and efficient. The latch rack and the traction plate rack are installed at the front and rear ends of multiple vehicles respectively, which can realize the connection between multiple vehicles and improve transportation efficiency.
