As shown in fig. 4, the front wheel steering mechanism 3 is mounted on one side of the vehicle body main frame 1 close to the lifting handle 25, and structurally comprises a front mounting plate 31, a first steering assembly mounted below the front mounting plate 31, and a front traction hook 36 for driving the first steering assembly to steer; the lifting handle 25 penetrates through the front mounting plate 31 and extends to the upper part of the lifting table surface 21, and a trolley handle 39 is also fixed above the front mounting plate 31; the first steering assembly comprises a pair of first steering wheel frames 32 hinged with the front mounting plate 31, first nylon wheels 33 mounted on the first steering wheel frames 32, and first steering guide rods 34 connected with the pair of first steering wheel frames 32, wherein two ends of each first steering guide rod 34 are respectively hinged with the first steering wheel frames 32, and a limiting rod 35 is arranged on the end surface of the middle part of each first steering guide rod; the front traction hook 36 is hinged with the front mounting plate 31, a waist-shaped limiting hole 37 for the limiting rod to slide is arranged on the end surface, and a square hole 38 is arranged at one end far away from the front mounting plate 31.

The steering drive of front wheel steering mechanism 3 mainly comes from preceding traction couple 36, when the corner appears with the rear axle line in the axis of front car, the front traction couple 36 of rear car will appear the corner with the axis of rear car, when the front traction couple 36 rotates, will drive first steering column and translate along lift mesa 21 minor axis direction to promote a pair of first nylon wheel 33 to take place to rotate, rotation angle directly by the axis of the preceding same orbit E type trailer, the axis of the following same orbit E type trailer and the contained angle difference of the rear wheel steering angle of the preceding same orbit E type trailer determine.

As shown in fig. 5, the rear wheel compensating mechanism 4 is installed on one side of the main frame 1 of the vehicle body away from the lifting handle 25, and structurally comprises a rear mounting plate 41, a second steering assembly installed below the rear mounting plate 41, and a rear steering hanger 45 for driving the second steering assembly to steer; the second steering assembly comprises a pair of second steering wheel frames 42 hinged with the rear mounting plate 41, second nylon wheels 43 mounted on the second steering wheel frames 42, and second steering guide rods 44 connected with the pair of second steering wheel frames 42, wherein two ends of the second steering guide rods 44 are respectively hinged with the second steering wheel frames 42; two ends of the rear steering hook 45 are respectively hinged with the second steering guide rod 44 and the rear mounting plate 41; meanwhile, the rear mounting plate 41 is further provided with a compensation adjusting plate 46, a pair of limiting columns 47 is arranged in the compensation adjusting plate 46, and the pair of limiting columns 47 are respectively located on two sides of the rear steering hook 45.

Because the E-type trailer with the same track needs to be sequentially pulled during working, the front traction hook 36 of the rear E-type trailer with the same track needs to be connected with the rear steering hook 45 of the front E-type trailer with the same track, as shown in fig. 5, during connection, the square hole at the end part of the front traction hook 36 is matched and connected with the end part of the rear steering hook 45 and is locked and fixed, and therefore the rear steering hook 45 and the front traction hook 36 are always on the same straight line.

The steering drive of the rear wheel compensation mechanism 4 mainly comes from the front traction hook 36 of the rear same-track E-type trailer, when the included angle between the axis of the rear same-track E-type trailer and the axis of the front same-track E-type trailer occurs, the front traction hook 36 of the rear same-track E-type trailer will have a deflection angle, and because the adjacent rear steering hook 45 and the front traction hook 36 are always on the same straight line, the rear steering hook 45 can drive the second steering guide rod 44 to deflect and drive the pair of second nylon wheels 43 to rotate.

The utility model discloses a concrete theory of operation as follows:

(1) feeding: when products, waste materials or residual materials need to be transported to a designated place, the trolley with the products or the residual materials is pushed to an E-shaped opening of the lifting table surface 21, the trolley is positioned above the lifting table surface 21, and then the lifting handle 25 is pushed to lift the lifting table surface 21 to the highest position and be used for bearing the trolley;

(2) blanking: the AGV pulls the E-shaped trailer with the same track to stop at a discharging point, after a worker of the production line pushes the lifting handle 25, the lifting main frame 23 slowly descends to the lowest point under the auxiliary action of the damper 27, the small trolley on the lifting table surface 21 stably falls on the ground, and the worker only needs to pull the small trolley out of the E-shaped opening and push the small trolley to a production line station;

(3) turning: when the AGV pulls the E-type trailer with the same track to turn for 90 degrees, the axis of the AGV and the axis of the first E-type trailer with the same track are deviated, so that the deviation angle of the front traction hook 36 begins to increase along with the increase of the turning angle, and gradually returns to be positive along with the decrease of the turning angle when the deviation angle is increased to a certain range, meanwhile, the first E-type trailer with the same track drags the second E-type trailer with the same track to turn, and when the front traction hook 36 of the second E-type trailer with the same track begins to deviate, the second steering assembly of the first E-type trailer with the same track is driven to rotate; due to the arrangement of the compensation adjusting plate 46 and the pair of limiting columns 47, when the second steering component of the first co-track E-type trailer rotates to the maximum value, the rotation is stopped, but the front wheel steering mechanism 3 of the second vehicle continues to rotate, when the axle clip angle of the co-track E-type trailer is reduced, the first steering component of the second co-track E-type trailer starts to return to the right, and then the second steering component of the first co-track E-type trailer also starts to return to the right, and when the axle lines are collinear, the second steering component of the first co-track E-type trailer and the first steering component of the second co-track E-type trailer completely return to the right and enter a straight-driving state; by analogy, the AGV can hang up to 16 trailers with the E-shaped track in the working process.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and therefore, the present invention is considered to be exemplary and not restrictive in any way, since the scope of the present invention is defined by the appended claims, rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and therefore any reference signs in the claims are not intended to be construed as limiting the claims concerned.
