[0005] This application utilizes a holding device to grasp and handle steel arch frames, and configures the supporting crossbeams to travel along the supporting longitudinal beams. This enables the steel arch frame stacking equipment to acquire and transport steel arch frames, meeting the requirements for transporting and stacking them. Furthermore, the steel arch frame stacking equipment of this application can achieve automated transport and stacking of steel arch frames by controlling the first, second, and third drive motors via a control unit.

[0006] In some embodiments of this application, the steel arch stacking equipment further includes two holding devices, which are spaced apart and mounted on the supporting crossbeam, with the clamping direction of each holding device perpendicular to the extension direction of the supporting crossbeam. By providing two holding devices, this application can acquire and transfer the steel arch through the synergistic action of the two devices, thereby more reliably constraining the steel arch and thus more reliably stacking the steel arch.

A load-bearing crossbeam 2 spans across the load-bearing longitudinal beams 1, and the first drive motor 51 is configured to drive the load-bearing crossbeam 2 to move along the load-bearing longitudinal beams 1.

[0045] 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, and it can be manufactured from profiles, such as square steel pipes, I-beams, etc. Specifically, as follows... Figure 1 and Figure 2 As shown, the load-bearing longitudinal beam 1 is made of square tubing, and each load-bearing longitudinal beam 1 is horizontally arranged and supported by two support columns.

[0046] The control unit in this application is not specifically limited and can be any unit that meets the control requirements. In specific implementations, the control unit can be selectively a microcontroller, a PLC programmable logic controller, or an industrial control computer.

[0047] In specific implementation, the holding and placing device 4 includes a first mounting base 43, a lifting arm 44, and a holding and placing unit. Specifically, as follows... Figure 1 , Figure 1.1 and Figure 2 As shown, the first mounting base 43 is connected to the supporting crossbeam 2. The lifting arm 44 is vertically arranged and connected to the first mounting base 43. The second drive motor 52 is configured to drive the lifting arm 44 to lift. This application uses the holding device 4 to hold the steel arch frame 10 and configures the supporting crossbeam 2 to move along the supporting longitudinal beam 1, thereby enabling the steel arch frame stacking equipment to acquire and transfer the steel arch frame 10 to meet the requirements for the transfer and stacking of the steel arch frame 10.

[0048] The holding and placing unit includes a first holding and placing member 41, a second holding and placing member 42, and a third drive motor 53. Specifically, as follows... Figure 4 , Figure 4.1 and Figure 5 As shown, the first holding member 41 is fixed to the lower end of the lifting arm 44, and the second holding member 42 is connected to the lower end of the lifting arm 44 and is directly opposite to the first holding member 41.

[0049] The first drive motor 51, the second drive motor 52, and the third drive motor 53 are all connected to and controlled by the control unit. In actual operation, the steel arch frame stacking equipment of this application can acquire and transfer the steel arch frame 10 by controlling the first drive motor 51, the second drive motor 52, and the third drive motor 53 through the control unit, so as to realize the automated transfer and stacking of the steel arch frame 10, effectively improving the transfer and stacking efficiency of the steel arch frame 10 and reducing the labor intensity of workers.

[0050] It should be noted that the first and second holding members in this application are not specifically limited, and can be any structure that can hold and release the steel arch frame 10 through mutual cooperation. Specifically, as shown below... Figure 1.1 , Figure 4 , Figure 4.1 and Figure 5 As shown, both the first holding member 41 and the second holding member 42 are slatted clamping members, and both extend vertically downwards. This application, by having the first holding member 41 and the second holding member 42 included in the holding device 4 clamp the steel arch frame 10, can better meet the needs of automated operation for acquiring and releasing the steel arch frame 10.

[0051] As some preferred embodiments of this application, the steel arch stacking equipment further includes two holding devices 4. Specifically, as follows... Figure 1 , Figure 2 and Figure 3 As 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 obtain and transfer the steel arch frame 10 through the cooperative action of the two holding devices 4, which can more reliably constrain the steel arch frame 10, and thus more reliably stack the steel arch frame 10.

By providing the fourth drive motor 54, this application can adjust the position of the holding device 4 on the supporting crossbeam 2 as needed, enabling the steel arch stacking device to meet the stacking needs of steel arches of different sizes and models.

[0053] As some preferred embodiments of the foregoing implementation, the steel arch stacking equipment further includes a first guide rail 21, a first slider 22, a first rack 23, and a first gear.

The first slider 22 is mounted on the first mounting base 43, and the first slider 22 is slidably adapted to the first guide rail 21. The first rack 23 is mounted on the supporting crossbeam 2 and is parallel to the first guide rail 21. The first gear is driveably connected to the power output end of the fourth drive motor 54, and the first gear (not shown in the figure) meshes with the first rack 23.

[0054] This application constrains the first mounting base 43 by setting the first guide rail 21 and the first rack 23, thereby better ensuring the positional accuracy of the holding device 4, so as to better meet the needs of automated transfer and stacking of the steel arch frame 10.

[0055] As some preferred embodiments of the foregoing implementation, the steel arch stacking equipment further includes a second guide rail 441, a second slider 442, a second rack, and a second gear. Specifically, as follows... Figure 1 , Figure 1.1 , Figure 4 and Figure 5 As shown, the second guide rail 441 is mounted on the lifting arm 44 and extends vertically.

[0056] In actual operation, the second drive motor 52 is controlled to drive the second gear and the second rack, thereby causing the lifting arm 44 to rise or fall vertically. This application constrains the lifting arm 44 by setting the second guide rail 441 and the second rack, which can better ensure the positional accuracy of the holding unit, and can more accurately acquire and release the steel arch frame 10, effectively improving the reliability of the steel arch frame stacking equipment.

[0057] As some preferred embodiments of this application, the holding device 4 further includes a second mounting base 45, a third guide rail 46, and a third slider 47. Specifically, as follows...

[0060] As an alternative implementation, the first engaging protrusion 411 opposite to the second holding member 42 may be selectively provided only on the first holding member 41, or the second engaging protrusion 421 opposite to the first holding member 41 may be provided only on the second holding member 42. The action of the first engaging protrusion 411 and / or the second holding member 42 can also prevent the steel arch frame 10 from falling off during transport, ensuring the normal and safe stacking of the steel arch frame 10.

[0061] 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.
