Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a conveying device used in steel structure processing. Background Technology

[0002] Steel structures, with their advantages of high strength, good seismic performance, and convenient assembly, are widely used in engineering fields such as industrial plants, high-rise buildings, and long-span bridges. They can serve as core load-bearing components in fields such as construction and bridges, and their processing accuracy and conveying efficiency directly determine the subsequent assembly quality and production cycle.

[0003] Application No. 202421953879.7 discloses a conveying device for steel structure processing. This device independently limits the two flanges of an I-beam through a left-side correction mechanism and a right-side correction mechanism. By adjusting the height of the correction mechanism, it can accommodate I-beam profiles with unequal flange lengths, solving the problem of limit failure caused by flange length differences in traditional conveying devices. However, during the conveying process, the left-side and right-side correction mechanisms can only achieve vertical height adjustment. In actual production, the dimensional differences of I-beams are not only reflected in the flange length, but also in different models of I-beams. The spacing between the flanges (i.e., the width of the web) of the steel also varies. When conveying I-beams of different widths, the correction mechanism cannot adjust the position of the limiting wheel in the horizontal direction, making it difficult to control the fit between the limiting wheel and the side wall of the flange. If the spacing between the limiting wheel and the flange is too large, the I-beam will move left and right during the conveying process, failing to play an effective correction role. If the spacing is too small, the limiting wheel will be excessively squeezed against the side wall of the flange, increasing the conveying resistance, and even causing wear on the flange surface or conveying jamming. Ultimately, this affects the conveying stability and processing accuracy of the I-beam, limiting the device's adaptability to I-beams of various specifications. Utility Model Content

[0004] This utility model proposes a conveying device for steel structure processing to solve the problems of existing conveying devices whose correction mechanism can only adjust the vertical height and cannot adjust the horizontal position, making it difficult to adapt to I-beams with different flange spacings, and easily causing the limit to be too loose or too tight, thus affecting the conveying stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying device for steel structure processing, comprising a base plate, an mounting frame mounted on the upper surface of the base plate, a conveying component for conveying the steel structure mounted on the mounting frame, and multiple correction structures evenly distributed on both sides of the mounting frame, each correction structure including a mounting base connected to the upper surface of the base plate, and an adjustment structure provided at the connection between the multiple mounting bases and the base plate for adjusting the horizontal spacing between the correction structures on both sides to adapt to steel structures with different wing plate spacings, and a limiting component provided on the outer side of the adjustment structure for providing guiding constraints for the movement of the correction structure and ensuring the accuracy of the spacing adjustment.

[0006] Preferably, the adjustment structure includes a slot formed in the inner wall of the base plate, and a plurality of synchronous pulleys adapted to the one-sided correction structure are rotatably connected inside the slot. A synchronous belt is sleeved on the outside of the plurality of synchronous pulleys, and an L-shaped movable plate is fixedly connected to the side wall of the mounting base.

[0007] Preferably, the adjustment structure further includes a connecting shaft fixedly connected between the two synchronous pulleys, one end of the synchronous pulley away from the connecting shaft is connected to a drive motor, and the two ends of the synchronous belt are respectively fixedly connected to the side walls of two parallel L-shaped movable plates.

[0008] Preferably, the limiting component includes a fixing plate fixedly connected to one side of the upper surface of the L-shaped movable plate, and a rotating shaft is rotatably connected in a pre-drilled shaft hole in the fixing plate, with gears fixedly connected to both ends of the rotating shaft.

[0009] Preferably, the limiting component further includes a horizontal plate fixedly connected to the upper end face of the base plate and located outside the L-shaped movable plate, wherein the upper end face of the horizontal plate is fixedly connected with a plurality of tooth blocks that mesh with the gear.

[0010] Preferably, the correction structure further includes a lifting cylinder installed on the upper surface of the mounting base. The free end of the lifting cylinder is connected to a first connecting plate. A connecting rod is connected to a rod groove pre-cut in the inner wall of the first connecting plate by mounting bolts. The end of the connecting rod away from the first connecting plate is connected to a second connecting plate.

[0011] Preferably, the second connecting plate is composed of two halves, each half having a vertical rod connected through it, and the upper end face of each vertical rod having a limit wheel connected to it. A driving component is provided between the second connecting plate and the first connecting plate.

[0012] Preferably, the outer wall of the mounting bracket is provided with a through groove, and the through groove is provided on the outside of the horizontal plate.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: (1) This application is equipped with an adjustment structure, which realizes the adjustment of the horizontal distance between the two correction structures. It can quickly adapt to I-beams with different wing plate distances, and fundamentally solves the problem of excessively loose or tight limit due to the inability to adjust the distance in traditional devices. At the same time, its transmission method has the characteristics of smooth transmission and high adjustment accuracy, which can ensure the synchronicity of the distance adjustment of the correction structures on both sides, effectively avoid the occurrence of unilateral deviation, and further improve the limit stability during the steel structure conveying process. (2) This application is equipped with a limit component, which forms a rigid transmission constraint through the meshing of gears and tooth blocks. This component can provide a stable guide trajectory for the movement of the mounting base and the correction structure. This component can effectively offset the slight slippage problem caused by wear and tension changes of the synchronous belt due to long-term use, and avoid displacement deviation of the correction structure during the adjustment process. In addition, the rigid meshing constraint of gears and tooth blocks can ensure the accuracy and consistency of the spacing adjustment, so that the limit wheel is always in precise contact with the side wall of the I-beam wing plate. This not only prevents the I-beam from moving left and right during the transport, but also avoids the wear of the wing plate caused by excessive compression, which significantly improves the device's adaptability to multiple specifications of I-beams and the stability of the transport.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 and Figure 2 As shown, the conveying device for steel structure processing includes a base plate 1, an mounting frame 2 is installed on the upper end surface of the base plate 1, and a conveying component 3 for conveying steel structures is installed on the mounting frame 2. (The conveying component 3 adopts a mature existing drive conveying structure, which is assembled from a motor, multiple drive rollers and a conveyor belt. The connection relationship between its components and the working principle of power transmission and conveying drive are common knowledge in the relevant technical field, and will not be described in detail in this application).

[0018] Multiple correction structures 4 are evenly distributed on both sides of the outer side of the mounting frame 2. Each correction structure 4 includes a mounting base 41 connected to the upper end face of the base plate 1. The correction structure 4 also includes a lifting cylinder 42 installed on the upper end face of the mounting base 41. The free end of the lifting cylinder 42 is connected to a first connecting plate 43. A connecting rod 44 is connected to a rod groove reserved in the inner wall of the first connecting plate 43 by mounting bolts. The end of the connecting rod 44 away from the first connecting plate 43 is connected to a second connecting plate 45.

[0019] The second connecting plate 45 is composed of two halves, and vertical rods 46 are connected through each half. Limiting wheels 47 are connected to the upper end face of each of the two vertical rods 46. A driving component 48 is provided between the second connecting plate 45 and the first connecting plate 43. (The driving component 48 consists of a motor and two gear discs. The motor is mounted on the first connecting plate 43 and is connected to one of the gear discs. The two gear discs are meshed and are connected to the two vertical rods 46.)

[0020] Specifically, in use, firstly, according to the dimensions of the steel structure to be transported, operate the lifting cylinder 42 to drive the correction structure 4 to lift as a whole, and adjust the height of the limit wheel 47 to perfectly match the height position of the steel structure wing plate; then loosen the mounting bolts, hold and pull the connecting rod 44 outward, and with the elastic restoring force of the elastic block, drive the two halves of the second connecting plate 45 to separate from each other, flexibly adjust the horizontal distance between the two sets of limit wheels 47, and then embed the steel structure wing plate into the limiting space between the two sets of limit wheels 47; then release the connecting rod 44, and use the rebound force of the elastic block to make the limit wheel 47 and the side wall of the wing plate... After the components are tightly fitted, the mounting bolts are tightened to lock the position of the correction structure 4. After the conveying system is started, the motor of the conveyor component 3 drives the drive roller to rotate, which in turn drives the conveyor belt to rotate synchronously to transport the steel structure. At the same time, the motor on the drive component 48 drives one of the toothed discs to rotate. Through the meshing transmission between the toothed discs, the other toothed disc meshing with it rotates synchronously, which in turn drives the vertical rod 46 and the limiting wheel 47 installed at the end of the vertical rod 46 to rotate. The rotation of the limiting wheel 47 can effectively reduce the frictional resistance between the limiting wheel and the steel structure wing plate. Combined with the conveying power of the conveyor belt, the steel structure can be transported smoothly.

[0021] Among them, see Figure 3 and Figure 4 As shown, an adjustment structure 5 is provided at the connection between the multiple mounting bases 41 and the base plate 1, which is used to adjust the horizontal distance between the two side correction structures 4 to adapt to steel structures with different wing plate spacings.

[0022] The adjustment structure 5 includes a slot 51 opened in the inner wall of the base plate 1. The slot 51 is rotatably connected to a number of synchronous pulleys 52 that are adapted to the one-sided correction structure 4. The synchronous pulleys 52 are fitted with a synchronous belt 55. An L-shaped movable plate 56 is fixedly connected to the side wall of the mounting base 41.

[0023] The adjustment structure 5 also includes a connecting shaft 53 fixedly connected between two synchronous pulleys 52. One end of one of the synchronous pulleys 52 away from the connecting shaft 53 is connected to a drive motor 54. The two ends of the synchronous belt 55 are fixedly connected to the side walls of two parallel L-shaped movable plates 56 respectively.

[0024] Through the above technical solution: Before conveying, one of the synchronous pulleys 52 is driven to rotate by the drive motor 54. At the same time, multiple synchronous pulleys 52 are driven to rotate synchronously via the connecting shaft 53, causing the synchronous pulleys 52 to drive the synchronous belt 55. The two mounting bases 41 move synchronously in opposite directions under the tension of the synchronous belt 55, thereby adjusting the distance between the two correction structures 4. This structure breaks through the limitation of existing devices that can only adjust the height of the limit wheel 47, realizing the automated and synchronized adjustment of the horizontal distance of the correction structure 4. It can quickly adapt to I-beams with different wing plate distances and solves the problem of excessively loose or tight limit due to the inability to adjust the distance in traditional devices. At the same time, the transmission method of the synchronous pulley group is smooth and has high adjustment accuracy, which can ensure the synchronicity of the distance adjustment of the correction structures 4 on both sides, avoid unilateral deviation, and further improve the limit stability during the conveying process.

[0025] See Figure 1 , Figures 3-5 As shown, a limiting component 6 is provided on the outer side of the adjustment structure 5 to provide guiding constraints for the movement of the correction structure 4 and to ensure the accuracy of the spacing adjustment.

[0026] The limiting component 6 includes a fixed plate 61 fixedly connected to one side of the upper end face of the L-shaped movable plate 56. A rotating shaft 62 is rotatably connected in a pre-drilled shaft hole in the fixed plate 61. Gears 63 are fixedly connected to both ends of the rotating shaft 62.

[0027] The limiting component 6 also includes a horizontal plate 64 fixedly connected to the upper end face of the base plate 1 and located outside the L-shaped movable plate 56. The upper end face of the horizontal plate 64 is fixedly connected with a plurality of tooth blocks 65 that mesh with the gear 63.

[0028] Through the above technical solution: During the adjustment of the distance between the two correction structures 4, the gear 63 on the L-shaped movable plate 56, connected by the fixed plate 61 and the rotating shaft 62, maintains meshing motion with multiple tooth blocks 65 on the upper surface of the horizontal plate 64. The meshing of the two forms a rigid transmission constraint. This component can provide a stable guide trajectory for the movement of the mounting base 41 and the correction structure 4, effectively offsetting the slight slippage problem caused by wear and tension changes of the synchronous belt 55 due to long-term use, and avoiding displacement deviation of the correction structure 4 during the adjustment process. In addition, the rigid meshing constraint between the gear 63 and the tooth blocks 65 can ensure the accuracy and consistency of the distance adjustment, so that the limit wheel 47 is always precisely in contact with the side wall of the I-beam flange. This not only prevents the I-beam from moving left and right during transportation, but also avoids the wear of the flange caused by excessive compression, significantly improving the device's adaptability to multiple specifications of I-beams and the stability of transportation.

[0029] Additionally, see Figure 1 As shown, the outer wall of the mounting bracket 2 is provided with a through groove 7, which covers the outside of the horizontal plate 64.

[0030] Specifically, with the help of the pre-set through groove 7 on the mounting bracket 2, a stable through channel can be provided for the gear 63, the fixing plate 61 and the rotating shaft 62, which facilitates the normal use of the limiting component 6.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
