[0043] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0044] The following is based on Figures 1 to 5 This invention introduces the steel arch frame stacking system and steel arch frame production line provided by this utility model.

[0045] The steel arch stacking system provided in this application includes a load-bearing longitudinal beam 1, a load-bearing transverse beam 2, a steel arch stacking area 3, and a holding device 4. For example... Figure 1 , Figure 2 and Figure 4As shown, two supporting longitudinal beams 1 are arranged side by side. A supporting crossbeam 2 spans across the supporting longitudinal beams 1 and is configured to move along the supporting longitudinal beams 1. The steel arch stacking area 3 is located directly below the running trajectory of the supporting crossbeam 2. This application uses a holding device 4 to clamp the steel arch 10 and configure the supporting crossbeam 2 to move along the supporting longitudinal beams 1, so that the steel arch stacking system can acquire and transfer the steel arch 10, thereby meeting the requirements for the transfer and stacking of the steel arch 10.

[0046] It should be noted that the load-bearing longitudinal beam in this application is not specifically limited. It can be any beam that meets the requirements for load bearing and the movement of the load-bearing transverse beam 2. It can be made of profiles, such as square steel pipes, I-beams, etc.

[0047] It should be explained that the steel arch frame stacking area 3 in this application is the working area for stacking the steel arch frames 10. In specific implementation, the steel arch frame stacking rack 100 is located in the steel arch frame stacking area 3. After the steel arch frames 10 are stacked, the steel arch frame stacking rack 100 is transferred to a designated location. There are no specific restrictions on the transfer method of the steel arch frame stacking rack 100; it can be transferred by a transfer vehicle or by a crane.

[0048] In specific implementation, such as Figure 1 and Figure 2 As shown, two load-bearing longitudinal beams 1 are arranged side by side and horizontally, and each load-bearing longitudinal beam 1 is supported by two support columns. A load-bearing crossbeam 2 is horizontally connected to the load-bearing longitudinal beams 1 in a direction perpendicular to them. It should be noted that the number of support columns supporting the load-bearing longitudinal beams 1 is not specifically limited and can be selectively set as needed. For example, the number of support columns supporting each load-bearing longitudinal beam 1 can be 3, 4, or 5, etc.

[0049] In a preferred embodiment of this application, the holding device 4 includes a first holding member 41 and a second holding member 42 disposed opposite to each other. In specific implementation, the first holding member 41 and the second holding member 42 are arranged in a first state of being close to each other to hold the steel arch frame 10 and a second state of being far apart to release the steel arch frame 10. It should be noted that, in specific implementation, the first holding member 41 can be selectively fixed, allowing the second holding member 42 to move closer to and further away from the first holding member 41; or the second holding member 42 can be fixed, allowing the first holding member 41 to move closer to and further away from the second holding member 42; or the first holding member 41 and the second holding member 42 can be selectively both moved towards each other or away from each other simultaneously.

[0050] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, two holding devices 4 are installed at intervals on the supporting crossbeam 2, and the clamping direction of each holding device 4 is perpendicular to the extension direction of the supporting crossbeam 2. By setting two holding devices 4, this application can realize the transfer and stacking of the steel arch frame 10 through the synergistic action of the two holding devices 4, and can more reliably constrain the steel arch frame 10 to better realize the stacking of the steel arch frame 10.

[0051] It should be noted that the first and second holding components in this application are not specifically limited; they can be any structure that, through mutual cooperation, can hold and release the steel arch frame. Specifically, as shown below... Figure 1.1 , Figure 4 , Figure 4.1 and Figure 5 As shown, the first gripper 41 and the second gripper 42 are slatted grippers, and both the first gripper 41 and the second gripper 42 extend vertically downwards. This application, by having the first gripper 41 and the second gripper 42 included in the holding and releasing device 4 grasp and release the steel arch frame 10, can better meet the needs of automated operation for the acquisition and release of the steel arch frame 10.

[0052] In some preferred embodiments of this application, the holding device 4 further includes a first mounting base 43 and a lifting arm 44. The first mounting base 43 is connected to the supporting beam 2 and is configured to move along the extension direction of the supporting beam 2. The lifting arm 44 is vertically mounted on the first mounting base 43 and is configured to rise and fall relative to the first mounting base 43. A first holding member 41 and a second holding member 42 are mounted at the lower end of the lifting arm 44. By including the lifting arm 44 in the holding device 4 and mounting the first holding member 41 and the second holding member 42 at the lower end of the lifting arm 44, this application enables the holding device 4 to be vertically adjusted according to the needs of transportation and stacking, thereby better meeting the requirements of transportation and stacking of the steel arch frame 10.

[0053] As some preferred embodiments of the foregoing implementation, the steel arch stacking system further includes a first guide rail 21, a first slider 22, and a first drive unit. The first guide rail 21 extends along the length of the supporting beam 2, and the first slider 22 is mounted on a first mounting base 43. The first slider 22 is slidably adapted to the first guide rail 21. The first drive unit is configured to drive the first mounting base 43 to move along the extension direction of the supporting beam 2.

[0054] It should be noted that the first drive unit in this application is not specifically limited, and it can be any drive unit capable of driving the first mounting base 43 to move along the extension direction of the bearing beam 2. In specific implementations, the first drive unit can be selectively a drive unit including a telescopic cylinder, or a drive unit including a drive motor and a linear transmission module (e.g., a linear module including gear and rack transmission, or a ball screw linear module, linear motor, belt-driven linear module, etc.).

[0055] It should be noted that there is no specific limit to the number of first guide rails 21 set on the load-bearing crossbeam 2. In order to provide better guidance for the first mounting base 43, such as Figure 1.1 As shown, two first guide rails 21 are provided on the supporting crossbeam 2, and the two first guide rails 21 are arranged on two adjacent surfaces of the supporting crossbeam 2; the first mounting base 43 includes two perpendicular surfaces, each surface being adapted and connected to the corresponding first guide rail 21 via at least one first slider 22.

[0056] In specific implementation, such as Figure 1.1 As shown, the steel arch stacking system also includes a first rack 23, which is mounted on the supporting beam 2 and extends along the length of the supporting beam 2. The first drive unit includes a first drive motor 51 and a first gear (not shown in the figure). The first drive motor 51 is mounted on a first mounting base 43, and the first gear is connected to the power output end of the first drive motor 51. The first gear meshes with the first rack 23. Preferably, the first drive motor 51 is a servo motor.

[0057] In practical operation, by controlling the first drive motor 51, the first drive motor 51 drives the first gear to rotate, and under the interaction of the first gear and the first rack 23, the position of the holding device 4 on the bearing beam 2 is adjusted. This application, by including the first drive motor 51, the first gear, and the first rack 23 in the steel arch stacking system, allows for the adjustment of the position of the first mounting base 43 on the bearing beam 2 through the control of the first drive motor 51. Furthermore, through the transmission of the first gear and the first rack 23, and under the constraint of the first guide rail 21 and the first slider 22, the positional accuracy of the holding device 4 can be better guaranteed, thereby meeting the needs of automated transfer and stacking. With this configuration, the position of the holding device 4 on the bearing beam 2 can also be adjusted according to the specifications and dimensions of the steel arch to be acquired.

[0058] As some preferred embodiments of this application, the steel arch stacking system includes a second guide rail 441, a second slider 442, and a second drive unit. For example...

The second slider 442 is mounted on the first mounting base 43, and the second slider 442 is slidably adapted to the second guide rail 441. The second drive unit is configured to drive the lifting arm 44 to move up and down in the vertical direction.

[0059] It should be noted that the second drive unit in this application is not specifically limited, and can be any unit capable of driving the lifting arm 44 to move up and down along the first mounting base 43. In specific implementations, the second drive unit can be a drive unit including a motor and a linear transmission module, or a drive unit including a telescopic cylinder.

[0060] As some preferred embodiments of the foregoing implementation, the steel arch stacking system includes a second rack (not shown in the figure), which is mounted on the lifting arm 44 and extends vertically. The second drive unit includes a second drive motor 52 and a second gear (not shown in the figure). The second drive motor 52 is mounted on a first mounting base 43, and the second gear is connected to the power output end of the second drive motor 52, meshing with the second rack. In operation, the second drive motor 52 is controlled, and the lifting arm 44 is driven to rise or fall through the meshing transmission of the second gear and the second rack. It should be noted that the structure of the first mounting base in this application can be selectively configured according to installation requirements.

[0061] As some preferred embodiments of this application, such as Figure 4 and Figure 4.1 As shown, the holding device 4 further includes a second mounting base 45, a third guide rail 46, a third slider 47, and a third drive unit. The second mounting base 45 is mounted on the lower end of the lifting arm 44, and the third guide rail 46 is horizontally mounted on the lower surface of the second mounting base 45. The third guide rail 46 extends horizontally along a direction perpendicular to the supporting beam 2, and a first holding member 41 is mounted on the lower part of the second mounting base 45. The third slider 47 is slidably adapted to the third guide rail 46, and the second holding member 42 is connected to the third slider 47 and is directly opposite the first holding member 41.

[0062] Furthermore, the third drive unit is connected to the second gripper 42, and the third drive unit is configured to drive the second gripper 42 closer to or further away from the first gripper 41. In actual operation, the positional relationship between the first gripper 41 and the second gripper 42 is adjusted by controlling the third drive unit, so that the first gripper 41 and the second gripper 42 are in a state of being close together to grip the steel arch frame 10, or in a state of being far apart to release the steel arch frame 10.

[0063] It should be noted that the third driving unit in this application is not specifically limited. It can be any driving unit that can drive the first gripper to move toward and away from the second gripper, or any driving unit that can drive the second gripper to move toward and away from the first gripper, or any driving unit that can drive the first gripper and the second gripper to move toward or away from each other.

[0064] As some preferred embodiments of the foregoing implementation methods, such as Figure 4.1 As shown, the third drive unit includes a third drive motor 53, a lead screw, and a nut adapted to the lead screw. The third drive motor 53 is mounted on the second mounting base 45. The third drive motor 53 is driveably connected to the lead screw, the nut is adapted to the lead screw, and the nut is connected to the second holding member 42. In actual operation, by controlling the third drive motor 53, the relative position of the second holding member 42 is adjusted under the transmission action of the lead screw and the nut.

[0065] Specifically, this application utilizes the cooperation of the third drive motor 53, the lead screw, and the nut to precisely adjust the positional relationship between the second holding member 42 and the first holding member 41, so as to better meet the automated picking and placing of the steel arch frame 10.

[0066] To enable the steel arch frame 10 to be engaged during transport and prevent it from shifting, thus better meeting the needs of automated palletizing, a first engaging protrusion 411 is provided on the first holding member 41, facing the second holding member 42; and a second engaging protrusion 421 is provided on the second holding member 42, facing the first holding member 41. Alternatively, the first engaging protrusion 411 facing the second holding member 42 may be selectively provided only on the first holding member 41, or only on the second holding member 42. Furthermore, the action of the first engaging protrusion 411 and / or the second holding member 42 can prevent the steel arch frame 10 from falling off during transport, ensuring the normal and safe implementation of the palletizing of the steel arch frame 10.

[0067] It should be noted that, in specific implementation, the number and arrangement of the first engaging protrusions 411 on the first holding member 41 are set according to actual needs; similarly, the number and arrangement of the second engaging protrusions 421 on the second holding member 42 are also set according to actual needs. Specifically, as follows... Figure 4 , Figure 4.1 and Figure 5 As shown, two engaging protrusions are provided on both the first holding member 41 and the second holding member 42. Furthermore, the engaging protrusions on both the first holding member 41 and the second holding member 42 are distributed vertically.

[0068] In order to enable the holding device to meet the holding needs of steel arch frames 10 of different models and sizes, it is further preferred that the first locking protrusion 411 provided on the first holding member 41 and / or the second locking protrusion 421 provided on the second holding member 42 be able to be adjusted in position.
