[0023] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0026] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0027] See also Figures 1 to 3As shown in the figure, according to an embodiment of the present invention, a stacking and transfer device suitable for large-mass metal elements is provided, including a carrying platform 31 and a traveling mechanism (not indicated in the figure). The traveling mechanism can drive the carrying platform 31 to move autonomously. The carrying surface of the carrying platform 31 is provided with a first sliding groove 311 and a second sliding groove 312. The length extension directions of the first sliding groove 311 and the second sliding groove 312 form a cross, that is, the first sliding groove 311 and the second sliding groove 312 are perpendicular to each other on the carrying surface of the carrying platform 31. The first sliding groove 311 is provided with two first positioning sliders 313 that can be driven to move closer or further away, and the second sliding groove 312 is provided with two second positioning sliders 314 that can be driven to move closer or further away. The two first positioning sliders 313 and the two positioning sliders 314 can adjust and position the metal elements placed on the carrying surface. It is understood that the aforementioned first positioning sliders 313 and second positioning sliders 314... 14 is preferably connected to the groove walls of the first groove 311 and the second groove 312 respectively to form a sliding guide connection to ensure the reliable and stable reciprocating linear motion of the first positioning slider 313 and the second positioning slider 314. The first positioning slider 313 and the second positioning slider 314 are specifically connected to the corresponding slider driving component 317 so that the operation of the slider driving component 317 can reliably drive the first positioning slider 313 and the second positioning slider 314. The slider driving component 317 can be, for example, a linear motor with sufficient output. Of course, in a preferred embodiment, a hydraulic cylinder can be used, which can have greater output and is applicable to a wider range of working conditions. More preferably, each of the first positioning slider 313 and the second positioning slider 314 is respectively provided with a slider driving component 317 so as to realize the flexible adjustment of the position of each positioning slider, thereby making the adjustment and positioning of the metal element placed on the bearing surface more flexible and accurate.

[0028] In this technical solution, the carrying platform 31 can move autonomously under the drive of the traveling mechanism, thereby efficiently adjusting the relative position between the carrying surface of the carrying platform 31 and the metal element to be stacked, i.e., achieving coarse adjustment and improving the alignment efficiency of metal element stacking. At the same time, a first positioning slider 313 and a second positioning slider 314 that move perpendicularly to each other are set on the carrying surface of the carrying platform 31 to achieve precise adjustment of the centering and positioning of the four mutually perpendicular positions of the metal element on the carrying surface, which can further improve the positional accuracy of the metal element, thereby improving the positional accuracy of the metal element after stacking. In addition, during the stacking process, the first positioning slider 313 and the second positioning slider 314, which form a clamping and positioning pair, can ensure the stability of the metal element during the stacking process and prevent positional deviation caused by the impact of placing the metal element during stacking.

[0029] In some embodiments, the carrying platform 31 has a first side (not shown in the figure) and a second side (not shown in the figure) that mate with a stacking limiting device (not shown in the figure, not indexed, which can guide and limit the left and right and front and back positions of the lifting clamp of the metal element to ensure the positional accuracy of the metal element during stacking). The first slide groove 311 is perpendicular to the first side and the second side. An assembly groove 315 is also constructed on the carrying surface. A support member 316 is assembled in the assembly groove 315. The support member 316 can support the bottom end face of the metal element and slide in contact with the bottom end face of the metal element. By supporting the bottom end face of the metal element with the support member 316, the friction between the metal element and the carrying surface can be reduced, thereby ensuring the smooth adjustment of the position of the metal element by the aforementioned first positioning slider 313 and second positioning slider 314.

[0030] In some embodiments, the aforementioned support member 316 can be a roller assembly (composed of multiple rollers) pivotally connected to the bearing surface. Although this type of support member 316 can achieve sliding contact with the bottom end face of the metal element, its bearing capacity is limited because the roller assembly requires a corresponding pivotal connection. This makes the pivotal connection prone to damage under the action of a large mass metal element, resulting in a short service life. In another preferred embodiment, the support member 316 is a support guide rail, which is fixedly assembled in the aforementioned assembly groove 315. The top surface of the support guide rail is provided with multiple balls (not shown in the figure) arranged along its length. According to the actual bearing requirements, the width of the top surface of the aforementioned support guide rail can be designed to be large to form a larger support plane. Correspondingly, multiple rows of balls are arranged along the width of the top surface of the rail. The support guide rail can withstand the weight of a large mass metal element, has a large bearing capacity, a reliable and stable structure, and a long service life. It is understood that each ball only needs to protrude slightly from the top surface of the rail, and the top surface of the rail can be at the same height as the aforementioned bearing surface. In a preferred embodiment, the support member 316 is symmetrically arranged on both sides of the first groove 311.

[0031] In some embodiments, the stacking and transfer device further includes a base platform 32, on which a rotating mechanism (not indicated in the figure) is provided. The rotating mechanism includes a turntable 321 and a rotating drive component 322 for driving the turntable 321 to rotate. The bearing platform 31 is assembled on the top surface of the turntable 321. In a feasible embodiment, a gear ring 3211 is formed on the circumferential outer wall of the turntable 321. The rotating drive component 322 has a corresponding output shaft, on which a corresponding drive gear is sleeved. The drive gear meshes with the gear ring 3211 to form a rotational drive of the turntable 321 by the rotating drive component 322. It should be noted that the rotating drive component 322 can be a corresponding rotating component with sufficient driving force, such as a hydraulic motor, a rotary motor, and a corresponding transmission and reduction mechanism. As a conventional design component in the mechanical field, this utility model will not elaborate on it.

[0032] In this technical solution, by setting the support platform 31 on a rotary table 321 that can be driven to rotate, the circumferential position of each stacked metal element can be adjusted by controlling the rotation of the rotary table 321. Thus, when welding the joints of adjacent metal elements, the corresponding welding device (not shown in the figure) does not need to move around the circumference of the metal element to achieve a fixed position (e.g., Figure 1 The rear end of the bearing platform 31 (as shown) facilitates the welding of the metal elements at various circumferential positions.

[0033] See details Figure 3 As shown, in some embodiments, an upward-facing assembly cavity (not indicated in the figure) is formed on the top surface of the base platform 32, the rotary disk 321 and the rotation drive component 322 are assembled in the assembly cavity, and the support platform 31 can completely cover the opening of the assembly cavity.

[0034] In this technical solution, an assembly cavity with an upward opening is formed on the top surface of the base platform 32, so that components such as the rotary table 321 and the rotary drive component 322 can be assembled in the assembly cavity, and the assembly cavity is sealed by the bearing platform 31. This makes the structure of the stacking and transfer device of this utility model more compact, and also improves the safety of the device.

[0035] In some embodiments, the traveling mechanism includes traveling wheels 331 located at the four corners of the supporting platform 31 and traveling drive components 332 for driving the synchronous rotation of each of the traveling wheels 331. In this case, the aforementioned traveling drive components 332 and slider drive components 317 are also housed within the aforementioned assembly cavity, further improving the structural compactness and operational safety of the device. It is understood that the aforementioned traveling drive components 332 can be equipped with corresponding hydraulic motors or electric motors and corresponding transmission and reduction devices. This is a relatively conventional design in the mechanical field, and this utility model will not elaborate on it.

[0036] In some embodiments, the stacking and transfer device further includes an auxiliary traction device 34, which is detachably connected to the base platform 32. That is, the auxiliary traction device 34 is an optional component that can be used when the stacking mass is large, so as to form a combined force with the aforementioned traveling drive component 332, thereby improving the traction power of the stacked metal units (bricks) and ensuring the efficient operation of the transfer.

[0037] To facilitate the connection process between the traction assist device 34 and the base platform 32, in some embodiments, the traction assist device 34 and the base platform 32 are electromagnetically attracted together. Specifically, the base platform 32 has a first traction rod 323, and a first electromagnetic chuck 3231 is fixedly connected to the free end of the first traction rod 323. The traction assist device 34 has a second traction rod 341, and a second electromagnetic chuck 3411 is fixedly connected to the free end of the second traction rod 341. The first electromagnetic chuck 3231 and the second electromagnetic chuck 3411 generate opposite magnetic fields when energized. Using electromagnetic chucks allows for adjustment of the magnetic attraction force by applying current, which is convenient and quick.

[0038] In some embodiments, both the first positioning slider 313 and the second positioning slider 314 have a positioning portion (i.e., the portion that contacts the metal base) protruding from the bearing surface and a connecting drive portion (i.e., the portion that connects to the slider driving component 317) located in the first slide groove 311 or the second slide groove 312. The top surface of the connecting drive portion is lower than the bearing surface by a height h, where h > 2 mm, to prevent the connecting drive portion from contacting and rubbing against the bottom end face of the metal base.

[0039] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
