[0042] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0045] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] During the production and processing of existing steel cages, it is necessary to transfer the steel cages from the previous process to the next process, such as from the assembly station to the welding station. The existing method of transporting the steel cages is a combination of hoisting and manual labor. However, due to the large length of the steel cages, which is about 12 meters in length, it is difficult to ensure the balance of the steel cages during the hoisting process, and there are many manual operations involved, resulting in high production efficiency and many safety hazards.

[0047] In order to solve this problem, this embodiment provides a conveying device, such as Figure 1As shown, the conveying device includes a base 300, a first conveying mechanism 100 and a second conveying mechanism 200. The first conveying mechanism 100 and the second conveying mechanism 200 are respectively arranged on the base 300. The base 300 plays a role of overall support. The first conveying mechanism 100 and the second conveying mechanism 200 are arranged in a line along the extension direction of the base 300. The first conveying mechanism 100 includes a first power trolley 101 and a first fixed trolley 102. The first power trolley 101 and the first fixed trolley 102 are used together to carry the workpiece to be processed, wherein the workpiece to be processed specifically refers to a steel cage. The second conveying mechanism 200 includes a second power trolley 201 and a second fixed trolley 202. The first power trolley 101 and the first fixed trolley 102, the second fixed trolley 202 and the second power trolley 201 are arranged in sequence along the conveying direction of the workpiece to be processed, that is, the second fixed trolley 202 is located between the first fixed trolley 102 and the second power trolley 201, and the first fixed trolley 102 is located between the first power trolley 101 and the second fixed trolley 202.

[0048] The first power trolley 101 is configured to drive the workpiece to be processed to move toward the first fixed trolley 102 and pass through the first fixed trolley 102, the second fixed trolley 202 and the second power trolley 201 in sequence, so that the second power trolley 201 can receive the workpiece to be processed and drive it to move away from the first conveying mechanism 100.

[0049] The conveying device provided in this embodiment first uses the first power trolley 101 and the first fixed trolley 102 to jointly carry the workpiece to be processed, so as to ensure that the workpiece to be processed with a longer length can be stably carried. As the first power trolley 101 pushes the workpiece to be processed to move in the direction close to the first fixed trolley 102, the free end of the workpiece to be processed after passing through the first fixed trolley 102 can act on the second fixed trolley 202. At this time, the workpiece to be processed is carried by the first power trolley 101, the first fixed trolley 102 and the second fixed trolley 202 at the same time, ensuring the reliability of the load at both ends and the middle position of the workpiece to be processed, until the second power trolley 201 takes over the workpiece to be processed. At this time, the four trolleys are all in contact with the workpiece to be processed, and the load-bearing and supporting effect is good. Then, under the driving action of the second power trolley 201, the workpiece to be processed is separated from the first power trolley 101, the first fixed trolley 102 and the second fixed trolley 202 in turn, thereby completing the conveying process of the workpiece to be processed, with a high degree of automation and high production efficiency. In this way, while ensuring good load-bearing and supporting effects for large workpieces to be processed, there is no need for direct contact and operation by the operator's hands, the safety factor is relatively high, and production safety is improved.

[0050] The first power trolley 101 and the second power trolley 201 have the same structure and are symmetrically arranged with respect to the center line of the base 300. The first fixed trolley 102 and the second fixed trolley 202 have the same structure and are symmetrically arranged with respect to the center line of the base 300. The two types of trolleys are introduced below.

[0051] like Figure 2 As shown, the first power trolley 101 and the second power trolley 201 both include a power trolley body 1, a horizontal conveying component 3 and a lifting drive source 2. The power trolley body 1 is used to carry the workpiece to be processed. The horizontal conveying component 3 is connected to the power trolley body 1 and can drive the power trolley body 1 to move in the horizontal direction. Under the action of the horizontal conveying component 3, the power trolley body 1 is driven and the workpiece to be processed is driven to be transported along the conveying direction. The lifting drive source 2 is connected to the power trolley body 1 and can adjust the height of the power trolley body 1 in the vertical direction, so that the power trolley body 1 can carry the workpiece to be processed. Through the mutual cooperation of the lifting drive source 2 and the power trolley body 1, the height adjustment of the power trolley body 1 is realized, which is convenient for the power trolley body 1 to undertake or detach from the workpiece to be processed, free and flexible, and reliable.

[0052] Furthermore, the horizontal conveying assembly 3 includes a rotating driving source 31, a driving wheel 32, a driven wheel 33 and a conveyor belt 34. The rotating driving source 31 is specifically a rotating motor. The rotating driving source 31 is fixed to the base 300 by bolts. The conveyor belt 34 is respectively wound around the driving wheel 32 and the driven wheel 33 and respectively connected to the two sides of the power trolley body 1. If the driving wheel 32 and the driven wheel 33 are rollers, the conveyor belt 34 is specifically a belt. If the driving wheel 32 and the driven wheel 33 are sprocket wheels, the conveyor belt 34 is specifically a chain. The conveyor belt 34 is not a complete closed-loop structure. The power trolley body 1 is arranged between the two free ports 35 of the conveyor belt 34. The two free ports 35 of the conveyor belt 34 are respectively connected to the two sides of the power trolley body 1, so that both sides of the power trolley body 1 can be subjected to the pulling force. The power trolley body 1 can have two opposite movement directions and can stretch the two sides of the power trolley body 1 to avoid the power trolley body 1 from tipping over, and the balance is good. The rotary drive source 31 can drive the driving wheel 32 to rotate, and drive the driven wheel 33 to rotate and the conveyor belt 34 to move. With the movement of the conveyor belt 34, the power trolley body 1 is pulled to move. This method has a simple structure and is easy to use.

[0053] like Figure 2As shown, the power trolley body 1 includes an upper fixing frame 11 and a lower fixing frame 12. The lower fixing frame 12 is located below the upper fixing frame 11 and is arranged parallel to the upper fixing frame 11. The upper fixing frame 11 can support the workpiece to be processed, and the lower fixing frame 12 can slide relative to the base 300. The height adjustment of the power trolley body 1 in the vertical direction is manifested as adjusting the distance between the upper fixing frame 11 and the lower fixing frame 12.

[0054] In order to solve this problem, the power vehicle body 1 further includes a first connecting rod 13 and a second connecting rod 14. The two ends of the first connecting rod 13 are respectively rotatably connected to the upper fixing frame 11 and the lower fixing frame 12. The two ends of the second connecting rod 14 are respectively rotatably connected to the upper fixing frame 11 and the lower fixing frame 12. The first connecting rod 13 and the second connecting rod 14 play the role of connecting the upper fixing frame 11 and the lower fixing frame 12. The second connecting rod 14 is rotatably connected to the first connecting rod 13 through the rotating shaft 24 and forms an X-shaped structure with the first connecting rod 13. With this structure, if the first connecting rod 13 and the second connecting rod 14 move in a direction close to each other, the opening of the X-shaped structure becomes smaller and the height of the X-shaped structure increases accordingly; if the first connecting rod 13 and the second connecting rod 14 move in a direction away from each other, the opening of the X-shaped structure becomes larger and the height of the X-shaped structure decreases accordingly.

[0055] In order to facilitate the adjustment of the height of the X-shaped structure, preferably, the lifting drive source 2 is a pneumatic cylinder or an oil cylinder, one end of the lifting drive source 2 is rotatably connected to the lower fixed frame 12, and the other end is rotatably connected to the first connecting rod 13 or the second connecting rod 14, that is, the fixed end of the lifting drive source 2 is hinged to the lower fixed frame 12, and the free output end of the lifting drive source 2 is hinged to the first connecting rod 13. If the output end of the lifting drive source 2 is extended, the first connecting rod 13 and the second connecting rod 14 are pushed to move in a direction close to each other, the first connecting rod 13 and the second connecting rod 14 are close to and contracted, and the height of the power trolley body 1 is increased to accommodate the workpiece to be processed; if the output end of the lifting drive source 2 is retracted, the first connecting rod 13 and the second connecting rod 14 are pushed to move in a direction away from each other, the first connecting rod 13 and the second connecting rod 14 are far away from and expanded, and the height of the power trolley body 1 is reduced to detach from the workpiece to be processed.

[0056] If the top surface of the upper fixing frame 11 is directly used to support the workpiece to be processed, the workpiece to be processed may impact the upper fixing frame 11 and be damaged. In addition, for the workpiece to be processed with a cylindrical shape, it may roll on the upper fixing frame 11.

[0057] To solve this problem, Figure 3As shown, the power trolley body 1 also includes a first roller seat 15, a second roller seat 16, an intermediate roller seat 17, a first roller 18, a first roller 19, a second roller 20 and a second roller 21. The first roller seat 15, the second roller seat 16 and the intermediate roller seat 17 are all arranged on the top surface of the upper fixed frame 11, the intermediate roller seat 17 is located between the first roller seat 15 and the second roller seat 16, the first roller 18 is arranged between the first roller seat 15 and the intermediate roller seat 17 and penetrates the first roller 19, the first roller seat 15 and the intermediate roller seat 17 are used to install the first roller 18, both of which provide support points for the two ends of the first roller 18, and the first roller 18 provides a rotation center for the first roller 19. The second roller 20 is arranged between the second roller seat 16 and the intermediate roller seat 17 and penetrates the second roller 21, and the first roller 19 and the second roller 21 jointly carry the workpiece to be processed. The second roller seat 16 and the middle roller seat 17 are used to install the second roller 20 , and both provide support points for both ends of the second roller 20 . The second roller 20 provides a rotation center for the second roller 21 .

[0058] Since the first roller 19 and the second roller 21 are higher than the top surface of the upper fixed frame 11, when the workpiece to be processed falls, the workpiece to be processed will first contact the first roller 19 and the second roller 21, and the first roller 19 and the second roller 21 jointly carry the workpiece to be processed. During the contact process, the first roller 19 and the second roller 21 will rotate relative to their respective rollers to avoid rigid collision between each roller and the workpiece to be processed. It can be understood that since the first roller 19 and the second roller 21 can rotate freely, when the workpiece to be processed is separated, there is rolling friction between the two rollers and the workpiece to be processed, the friction force is small, and the separation obstacle is relatively small, which is convenient for the separation of the workpiece to be processed.

[0059] Preferably, the axes of the first roller 18 and the second roller 20 are inclined relative to the vertical direction, so that the first roller 19 and the second roller 21 are arranged in a V-shaped structure, and the large end of the V-shaped structure is arranged away from the upper fixed frame 11. Through this arrangement, the large end of the V-shaped structure is convenient for the placement of the workpiece to be processed, and the inner side of the V-shaped structure, that is, the first roller 19 and the second roller 21, can also play a role in limiting the workpiece to be processed, thereby preventing the workpiece to be processed from detaching from the upper fixed frame 11 during the conveying process, and has good position stability.

[0060] In order to further ensure the accuracy of the relative position between the workpiece to be processed and the upper fixed frame 11, as Figure 3As shown, one of the upper fixing frame 11 and the workpiece to be processed is provided with a positioning member 22, and the other is provided with a positioning groove, and the positioning member 22 is inserted into the positioning groove (not shown in the figure). In this embodiment, the upper fixing frame 11 is preferably provided with a positioning member 22, and the positioning member 22 is preferably a positioning plate erected on the upper fixing frame 11, and the workpiece to be processed is provided with a positioning groove, and the positioning plate is inserted into the positioning groove, which plays the role of initial positioning, and the positioning effect is good.

[0061] Furthermore, if Figure 4 As shown, running wheels 23 are provided at the bottom of the first power trolley 101 and the bottom of the second power trolley 201. In other words, running wheels 23 are provided at the bottom of the lower fixed frame 12. The running wheels 23 are arranged to roll relative to the base 300, so that the bottom of the first power trolley 101 and the second power trolley 201 can roll relative to the base 300.

[0062] In order to prevent the power trolley body 1 from deviating from its position during walking, a guide rail 301 is arranged on the top surface of the base 300 along the conveying direction of the workpiece to be processed, and a limiting groove is arranged on the outer wall of the walking wheel 23 along its circumference, and the guide rail 301 can partially extend into the limiting groove and slide with it.

[0063] The purpose of adopting this method is, first, by forming a limiting groove on the outer peripheral wall of the walking wheel 23, the power trolley body 1 can only move along the predetermined direction of the guide rail 301, and the limiting groove plays a limiting role, planning the moving trajectory of the power trolley body 1 to avoid position displacement; second, when the lifting drive source 2 drives the first connecting rod 13 or the second connecting rod 14 to move, it is necessary that the end of the first connecting rod 13 close to the lower fixed frame 12 and the end of the second connecting rod 14 close to the lower fixed frame 12 can both slide relative to the lower fixed frame 12, and the sliding cooperation between the guide rail 301 and the limiting groove plays a guiding effect, thereby ensuring the smoothness of the height adjustment of the power trolley body 1.

[0064] The first fixed trolley 102 and the second fixed trolley 202 have similar structures to the first power trolley 101 and the second power trolley 201, with the only difference being that: first, the bottom of the first power trolley 101 and the bottom of the second power trolley 201 are provided with running wheels 23, and the running wheels 23 are arranged to roll relative to the base 300. Figure 5As shown, the first fixed trolley 102 and the second fixed trolley 202 are fixed relative to the base 300, that is, the lower fixed frame 12 of the fixed trolley is directly fixed to the base 300 through the fixed seat 1021, and the fixed trolley can only realize the lifting function through the lifting drive source 2, but there is no horizontal conveying component 3, and the horizontal movement function cannot be realized; secondly, the first power trolley 101 and the second power trolley 201 are provided with positioning parts 22. Figure 6 As shown, the first fixed trolley 102 and the second fixed trolley 202 are not provided with positioning members 22, and other structures are similar, so they are not described in detail.

[0065] The working process of the conveying device provided in this embodiment is as follows:

[0066] During operation, after the upper mechanism fixes the workpiece to be processed, the first conveying mechanism 100 and the second conveying mechanism 200 are driven to rise simultaneously by their respective lifting drive sources 2. Since the length of the workpiece to be processed is relatively large, the first power trolley 101 and the first fixed trolley 102 in the first conveying mechanism 100 are first used to receive the workpiece to be processed. When the first rollers 19 and the second rollers 21 in the first power trolley 101 and the first fixed trolley 102 are in contact with the workpiece to be processed, the lifting drive sources 2 in the first conveying mechanism 100 and the second conveying mechanism 200 all stop working. At this time, the positioning member 22 of the first power trolley 101 is inserted into the positioning groove of the workpiece to be processed.

[0067] When the first power trolley 101 in the second conveying mechanism 200 is moved to a preset position close to the first conveying mechanism 100, the first power trolley 101 of the first conveying mechanism 100 is started to move the workpiece to be processed in a direction close to the second conveying mechanism 200. After the workpiece to be processed passes through the first fixed trolley 102 of the first conveying mechanism 100, it passes through the second fixed trolley 202 in the second conveying mechanism 200, and then continues to move forward to the first roller 19 and the second roller 21 of the second power trolley 201 in the second conveying mechanism 200, until the positioning hole of the workpiece to be processed moves forward to the positioning piece 22 of the second power trolley 201 in the second conveying mechanism 200. After the two are intertwined, the second power trolley 201 in the second conveying mechanism 200 continues to drive the workpiece to be processed forward until it moves to the rightmost side of the guide rail 301, thereby successfully moving the workpiece to be processed from the first conveying mechanism 100 to the second conveying mechanism 200;

[0068] Then the rollers of the next mechanism hold the workpiece to be processed, the lifting drive source 2 in the second power trolley 201 and the second fixed trolley 202 in the second conveying mechanism 200 retracts and returns to its original position, and the lifting drive source 2 in the first power trolley 101 and the first fixed trolley 102 in the first conveying mechanism 100 also retracts and returns to its original position, thereby completing a working cycle.

[0069] This embodiment also provides a processing arrangement, including the above-mentioned conveying device and welding device, wherein the conveying device is used to convey the workpiece to be processed to the welding device, with low production cost and high production efficiency.
