[0045] The fork sleeve comprises two outer fork sleeves 22a, and two inner fork sleeves 22b are provided between the two outer fork sleeves 22a. The rear ends of the two outer fork sleeves 22a and the rear ends of the two inner fork sleeves 22b are all welded and fixed to the front end of the lifting seat 21.

[0046] In order to improve the strength of the outer fork sleeve 22a and the inner fork sleeve 22b, reinforcing ribs 221 are welded and fixed to the top of the outer fork sleeve 22a and the top of the inner fork sleeve 22b, and the reinforcing ribs 221 are welded and fixed to the rear end and the front end of the lifting seat 21.

[0047] The bottom of the outer fork sleeve 22a and the bottom of the inner fork sleeve 22b are both provided with an opening 222.

A rotating shaft 315 is rotatably connected to the rotating base 314. A stop rod 316 is welded to the sidewalls of the rotating shaft 315.

[0051] The oil cylinder 32 can be a manual hydraulic cylinder. The bottom of the oil cylinder 32 is welded to the top of the base 11. A sprocket shaft 33 is welded to the top of the lifting rod of the oil cylinder 32. Both ends of the sprocket shaft 33 are rotatably connected to sprockets 34 through bearings.

[0052] The working principle of the feeding vehicle in this embodiment is as follows:

[0053] (1) When it is necessary to increase the length of the entire feeder in the front and rear straight directions:

[0054] The output end of the telescopic rod 17 extends, pushing the connecting rod 16 forward, and the connecting rod 16 drives the two sliding sleeves 15 forward, increasing the length of the exposed portion of the sliding rod 14 and increasing the distance between the front wheel 12 and the rear wheel 13, thereby increasing the length of the frame base in the front-to-back straight direction.

[0055] At the same time, as the sliding sleeve 15 moves forward, the sliding sleeve 15 drives the guide cylinder 19 forward, the guide cylinder 19 drives the guide rod 25 forward, the guide rod 25 drives the connecting plate 24 forward, and the connecting plate 24 drives the outer fork rod 23a and the inner fork rod 23b forward together, so that the length of the lifting frame in the front-to-back straight direction increases;

[0056] Because the length of the frame bottom and the lifting frame in the front-back straight direction increases, the length of the entire feeder in the front-back straight direction increases. When the length of the entire feeder in the front-back straight direction increases, the workpiece can be placed on the outer fork rod 23a and the inner fork rod 23b and the workpiece can be transported using the entire feeder.

[0057] (2) When it is necessary to reduce the length of the entire feeder in the front and rear straight directions:

[0058] The output end of the telescopic rod 17 retracts, and the output end of the telescopic rod 17 pulls the connecting rod 16 backward, and the connecting rod 16 drives the two sliding sleeves 15 to move backward, the length of the exposed portion of the sliding rod 14 is reduced, and the distance between the front wheel 12 and the rear wheel 13 is shortened, so that the length of the frame base in the front-to-back straight direction is reduced;

[0059] At the same time, as the sliding sleeve 15 moves backward, the sliding sleeve 15 drives the guide cylinder 19 to move backward, the guide cylinder 19 drives the guide rod 25 to move backward, the guide rod 25 drives the connecting plate 24 to move backward, and the connecting plate 24 drives the outer fork rod 23a and the inner fork rod 23b to move backward together, so that the length of the lifting frame in the front-to-back straight direction is reduced;

[0060] Because the length of the frame bottom and the lifting frame are reduced in the front-to-back straight direction, the length of the entire feeder cart in the front-to-back straight direction is also reduced. When the length of the entire feeder cart in the front-to-back straight direction is reduced, the volume of the entire feeder cart can be reduced, the space occupied by the entire feeder cart can be reduced, and the storage space can be conveniently stored, thereby improving the utilization rate of factory space.

[0061] (3) When the height of the lifting frame needs to be increased:

[0062] The lifting rod of the oil cylinder 32 extends upward, and the lifting rod of the oil cylinder 32 pushes the sprocket shaft 33 to move upward, and the sprocket shaft 33 drives the sprocket 34 to move upward, and the chain 35 pulls the lifting seat 21 to move upward, and the lifting seat 21 drives the outer fork sleeve 22a and the inner fork sleeve 22b to move upward, and the outer fork sleeve 22a drives the outer fork rod 23a to move upward, and the inner fork sleeve 22b drives the inner fork rod 23b to move upward, and the outer fork rod 23a and the inner fork rod 23b drive the connecting plate 24 to move upward, and the connecting plate 24 drives the guide rod 25 to move upward; and as the lifting seat 21 moves upward, the lifting seat 21 drives the mounting plate 211 to move upward, and the mounting plate 211 drives the limiting wheel 212 to move upward, and the limiting wheel 212 rolls upward in the limiting groove 313.

[0063] When the lifting seat 21, the outer fork sleeve 22a, the inner fork sleeve 22b, the outer fork rod 23a, and the inner fork rod 23b move upward, the height of the lifting frame is raised. When the height of the lifting frame is raised, the height of the workpiece placed on the outer fork rod 23a and the inner fork rod 23b is also raised.

[0064] When the lifting frame is adjusted to a commonly used height, the rotating shaft 315 can be rotated to move the limiting rod 316 on the side wall of the rotating shaft 315 to the bottom of the lifting frame. The limiting rod 316 can be used to abut the bottom of the lifting frame, so that the lifting frame is supported by the limiting rod 316, which is beneficial to further improve the stability of the lifting frame at the current height.

[0065] (4) When the height of the lifting frame needs to be lowered:

[0066] The lifting rod of the oil cylinder 32 retracts downward, and the lifting rod of the oil cylinder 32 drives the sprocket shaft 33 to move downward, and the sprocket shaft 33 drives the sprocket 34 to move downward, and the lifting seat 21 moves downward under the action of gravity, and the lifting seat 21 drives the outer fork sleeve 22a and the inner fork sleeve 22b to move downward, and the outer fork sleeve 22a drives the outer fork rod 23a to move downward, and the inner fork sleeve 22b drives the inner fork rod 23b to move downward, and the outer fork rod 23a and the inner fork rod 23b drive the connecting plate 24 to move downward, and the connecting plate 24 drives the guide rod 25 to move downward; and as the lifting seat 21 moves downward, the lifting seat 21 drives the mounting plate 211 to move downward, and the mounting plate 211 drives the limiting wheel 212 to move downward, and the limiting wheel 212 rolls downward in the limiting groove 313.

[0067] When the lifting seat 21, the outer fork sleeve 22a, the inner fork sleeve 22b, the outer fork rod 23a, and the inner fork rod 23b move downward, the height of the lifting frame is lowered. When the height of the lifting frame is lowered, the height of the workpiece placed on the outer fork rod 23a and the inner fork rod 23b is also lowered.

[0068] (5) When a feeding car is needed to feed the workpiece into the horizontal tempering furnace:

[0069] ① Increase the length of the entire feeding carriage in the front-to-back straight direction; ② Place the workpiece on the outer fork rod 23a and the inner fork rod 23b of the lifting frame; ③ Raise the height of the lifting frame until the height of the workpiece reaches the height of the inner tank of the horizontal tempering furnace; ④ Push the feeding carriage to send the lifting frame and the workpiece into the inner tank of the horizontal tempering furnace. At this time, the frame base enters the space between the bottom of the horizontal tempering furnace and the ground; ⑤ Lower the height of the lifting frame to make the workpiece fall onto the support frame in the inner tank of the horizontal tempering furnace; ⑥ Withdraw the feeding carriage and remove the lifting frame from the inner tank of the horizontal tempering furnace to complete the operation of sending the workpiece into the horizontal tempering furnace.

[0070] Through the above working principle, the feeding vehicle of this embodiment has the following effects:

[0071] First, when the output end of the telescopic rod 17 retracts, the length of the frame base and the lifting frame in the front-to-back straight direction can be reduced, so that the length of the entire feeding cart in the front-to-back straight direction is reduced, and the volume of the entire feeding cart is reduced. The feeding cart with reduced volume is more convenient to store, which is conducive to improving the utilization rate of the factory space.

[0072] Second, when the output end of the telescopic rod 17 is extended, the frame base and the lifting frame are extended in the front and rear straight directions, which allows the workpiece to be placed on the lifting frame, so that the workpiece can be transported using a feeding car.

[0073] Third, by providing the guide rods 25 and the guide cylinders 19, when adjusting the length of the frame base in the front-back straight direction, the guide rods 25 and the guide cylinders 19 can be used to drive the lifting frame to move in the front-back straight direction, thereby achieving synchronous adjustment of the lengths of the frame base and the lifting frame, which is conducive to improving the adjustment efficiency.

[0074] Fourth, by using a manual hydraulic cylinder, it can be operated conveniently.

[0075] Fifth, when adjusting the height of the lifting frame, the limiting wheel 212 at the rear end of the lifting frame can roll in the limiting groove 313 of the lifting column 31. The limiting groove 313 is used to limit the limiting wheel 212, which can improve the stability of the lifting frame during the lifting process and reduce the risk of shaking of the lifting frame, thereby helping to improve the stability of transporting workpieces.

[0076] Sixth, when the lifting frame is adjusted to a commonly used height, the limiting rod 316 can be rotated to the bottom of the lifting frame and the limiting rod 316 can be used to support the lifting frame, thereby improving the stability of the lifting frame at the current height.

[0077] Seventh, by providing a protective net 312 at the rear end of the lifting column 31 , the safety of the entire feeding vehicle can be improved.

[0078] Eighth, when conveying workpieces into the horizontal tempering furnace's inner chamber, guide wheels 18 cooperate with guide rails at the furnace's bottom to guide the workpieces axially along the furnace's inner chamber, preventing skew and improving feeding accuracy. Furthermore, the guide wheels 18 reduce the risk of left-right collisions on the entire transport vehicle.

[0079] Ninth, by providing reinforcing ribs 221 at the top of the outer fork sleeve 22a and the top of the inner fork sleeve 22b, the strength of the outer fork sleeve 22a and the inner fork sleeve 22b can be improved, thereby improving the reliability of bearing the workpiece.

[0080] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
