[0043] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0045] Example 1, such as Figure 1 - Figure 4 As shown, this utility model provides an annealing furnace loading and unloading trolley device capable of multi-directional conveying of workpieces, the specific concept of which is as follows:

[0046] An annealing furnace feeding and discharging trolley device includes: a single-layer trolley 1 and a conveying assembly;

[0047] The conveying assembly includes a two-layer trolley 2, the outer surface of which is slidably disposed on the outer surface of a one-layer trolley 1. Multiple fixed plates 201 are fixedly disposed on the outer surface of the two-layer trolley 2. Multiple vertical guide wheels 202 are rotatably mounted on the inner walls of the multiple fixed plates 201. A three-layer trolley 3 is slidably disposed on the outer surface of the multiple vertical guide wheels 202. Two wheels 5 are rotatably connected to both ends of the one-layer trolley 1. A reducer 6 is movably disposed on the outer surface of the two wheels 5. The two-layer trolley 2 and the fixed plates 201 move linearly on the outer surface of the one-layer trolley 1. The vertical guide wheels 202 follow the fixed plates 201 and move linearly. The three-layer trolley 3 moves vertically on the outer surface of the vertical guide wheels 202. The one-layer trolley 1 moves linearly in coordination with the wheels 5.

[0048] It should be noted that two motors 7 are fixedly installed on the outer surface of the first-layer trolley 1. The output ends of the two motors 7 are respectively fixedly connected to the other ends of the two reducers 6. Two sets of pulleys 205 are rotatably installed on the inner wall of the second-layer trolley 2. The outer surfaces of the two sets of pulleys 205 are slidably set on the outer surface of the first-layer trolley 1. When the motors 7 work with the reducers 6, they drive the wheels 5 to rotate. When the wheels 5 rotate, they rub against the contact surface and drive the first-layer trolley 1 to move linearly.

[0049] In addition, multiple connecting plates 8 are fixedly installed on the outer surface of the second-layer trolley 2, and two sets of transmission pins 203 are rotatably arranged on the inner wall of the second-layer trolley 2. Two electric motors 9 are fixedly installed on the outer surface of the first-layer trolley 1, and the output ends of the two electric motors 9 are fixedly connected to the reducers 10. The electric motors 9 drive the reducers 10 to work.

[0050] As an example, in this embodiment, the inner wall of the reducer 2 10 is rotatably provided with two transmission rods 4, and one end of each transmission rod 4 is fixedly mounted with a drive gear 204. The outer surface of the drive gear 204 meshes with the outer surface of the transmission pin 203. When the reducer 2 10 is working, it drives the transmission rods 4 to rotate. When the transmission rods 4 rotate, they drive the drive gear 204 to rotate. When the drive gear 204 rotates, it moves the transmission pin 203.

[0051] In this embodiment, when the motor 7 works in conjunction with the reducer 6, it drives the wheel 5 to rotate. When the wheel 5 rotates, it rubs against the contact surface, causing the first-layer trolley 1 to move laterally in a straight line. When the motor 9 works in conjunction with the reducer 10, it drives the transmission rod 4 to rotate. When the transmission rod 4 rotates, it drives the drive gear 204 to rotate. When the drive gear 204 rotates, it moves the transmission pin 203. After the transmission pin 203 is moved, it drives the second-layer trolley 2 and the connecting plate 8 to move longitudinally in a straight line.

[0052] Example 2, as Figure 1 - Figure 4 As shown, this utility model provides an annealing furnace loading and unloading trolley device capable of lifting and lowering workpieces. The specific concept is as follows:

[0053] An annealing furnace feeding and discharging trolley device includes: a lifting assembly;

[0054] It should be noted that the lifting assembly includes two sets of wedges 301. Two sets of wedges 301 are fixedly installed on the outer surface of the three-layer trolley 3. Wheels 302 are slidably installed on the outer surface of both sets of wedges 301. When the three-layer trolley 3 moves, it drives the wedges 301 to slide on the outer surface of the wheels 302, and the wheels 302 rotate after being subjected to friction.

[0055] As an example, in this embodiment, two sets of mounting plates 303 are rotatably provided on the outer surfaces of the two sets of wheels 302. The outer surfaces of the two sets of mounting plates 303 are fixedly installed on the outer surface of the second-layer trolley 2. When the second-layer trolley 2 moves, it drives the mounting plates 303 and wheels 302 to move longitudinally in a straight line.

[0056] In addition, a drive rod 304 is fixedly connected to one side of the two sets of mounting plates 303. A hydraulic rod 305 is fixedly connected to the outer surface of the drive rod 304. The other end of the hydraulic rod 305 is fixedly installed on the outer surface of the second-layer trolley 2. When the hydraulic rod 305 is working, its output end extends out to drive the drive rod 304 and the mounting plate 303 to move longitudinally in a straight line.

[0057] In this embodiment, when the hydraulic rod 305 is working, it drives the drive rod 304 and the mounting plate 303 to move longitudinally in a straight line. When the mounting plate 303 moves, it drives the second wheel 302 to move longitudinally in a straight line. When the second wheel 302 moves, it slides on the surface of the wedge block 301. The second wheel 302 pushes the wedge block 301 to move vertically in a straight line, thereby raising the height of the three-layer trolley 3. The second wheel 302 rotates after being subjected to friction.

[0058] Working Principle: When connected to an external power supply and external hydraulic system, the operator controls motor 7 in conjunction with reducer 6 to drive wheel 5 to rotate. The rotation of wheel 5, through friction with the contact surface, causes the first-layer trolley 1 to move laterally in a straight line. Simultaneously, motor 9 in conjunction with reducer 10 drives transmission rod 4 to rotate. The rotation of transmission rod 4 drives drive gear 204 to rotate, which in turn actuates transmission pin 203. This actuation of transmission pin 203 causes the second-layer trolley 2 and connecting plate 8 to move longitudinally in a straight line. This facilitates the docking of the first-layer trolley 1 with multiple annealing furnaces, while the second-layer trolley 2 docks with the tracks inside the annealing furnace and runs into it, improving adaptability to multi-furnace production lines. The second-layer drive can be selected to achieve single-layer operation as needed. The device can operate in both directions, making it easy to adapt to the feeding and discharging direction requirements of different production lines and improving its applicability. When the operator controls the hydraulic rod 305, it drives the drive rod 304 and the mounting plate 303 to move longitudinally in a straight line. When the mounting plate 303 moves, it drives the second wheel 302 to move longitudinally in a straight line. When the second wheel 302 moves, it slides on the surface of the wedge block 301. The second wheel 302 pushes the wedge block 301 to move vertically in a straight line, thereby raising the height of the three-layer trolley 3. In conjunction with the vertical guide wheel 202, it is easy to enhance the verticality and stability of the three-layer trolley 3 during lifting and lowering, which helps to prevent the workpiece from shifting or being damaged during the lifting and lowering process. The second wheel 302 rotates after being subjected to friction, which helps to reduce the friction force on the wedge block 301 and extend its service life.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
