DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] In the description of the present application, it should be understood that the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" and the like indicate the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0031] For the convenience of description, spatial relative terms such as "over", "above", "upper surface", "upper" and the like can be used herein to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawings is inverted, the device described as "above" or "over" other devices or structures will be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0032] In addition, it should be noted that the use of "first", "second" and the like to define parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore it cannot be understood as a limitation on the scope of protection of the present application.

[0033] See also Figures 1 to 5 As shown, the present invention provides a stacking limit device, which is particularly suitable for stacking large-mass metal elements, including at least two groups of limit components (not labeled in the figure), each group of the limit components is arranged in a circular stacking space (not shown in the figure, not labeled), and the aforementioned stacking space is also the target space for stacking the metal elements, each of the limit components includes a plurality of transverse limit components (not labeled in the figure) arranged in sequence up and down along the height direction, each of the transverse limit components includes a transverse drive component (not labeled in the figure) and a The limiter 11 can interfere with the outer wall of the metal element, and each of the transverse driving components includes a transverse push rod 121. The free end of the transverse push rod 121 is drive-connected to the limiter 11. Each of the transverse limiting components can operate independently to drive the corresponding limiter 11 to approach or move away from the metal element. It can be understood that the number of limiters 11 in the same limiter component can be equal to the number of metal elements to be stacked, and each limiter 11 is set in a one-to-one correspondence with each metal element.

[0034] In this technical solution, on the one hand, each limiting member 11 becomes a limiting reference for the metal elements corresponding to their positions during the stacking process, thereby effectively ensuring the stacking accuracy of the stacked metal elements, improving the stacking efficiency, and greatly eliminating the safety hazards of manual adjustment and alignment during the stacking of metal elements. On the other hand, since each transverse limiting component can independently control the operation and drive of the corresponding limiting member 11, the stacking limiting device can be applied to the stacking scene of special-shaped metal elements, ensuring high precision and high efficiency of the stacking process of irregular external contours. It can be understood that the aforementioned stacking limiting device is particularly suitable for working conditions where the lifting device for the metal elements adopts a flexible structure (such as a rope, chain, etc.), so that the position correction effect of each limiting member 11 on the metal elements during the stacking process can be fully exerted.

[0035] The aforementioned limiting member 11 can specifically be a limiting plate. In this case, the contact surface of the limiting plate should ensure sufficient smoothness to minimize the friction between the limiting plate and the side wall of the metal element. In addition, the upper and lower heights of each limiting plate should not be too large, so as to ensure that the side wall of a single metal element is non-planar. In another preferred embodiment not shown in the figure, the aforementioned limiting member 11 is a roller (a cylindrical roller in a specific embodiment), which is pivotally connected to the free end of the transverse push rod 121. The rotation axis of the roller is in the horizontal plane and perpendicular to the transverse extension and retraction direction of the transverse push rod 121. In this way, the limiting plate can reduce the friction between the limiting plate and the metal element while achieving the limiting effect of the limiting plate on the stacking and falling of the metal element.

[0036] In some embodiments, the horizontal movement driving assembly further comprises a screw rod 122, a guide rail 123, and a power device 124 for driving the screw rod 122 to rotate, the driving end of the horizontal movement ejector rod 121 is threadedly connected with the screw rod 122, and the driving end of the horizontal movement ejector rod 121 is also slidingly connected with the guide rail 123, the driving end of the horizontal movement ejector rod 121 is the end of the horizontal movement ejector rod 121 away from the limiting member 11 relative to the free end, and specifically, in an illustrated embodiment, the driving end of the horizontal movement ejector rod 121 is formed as a driving connecting member 1211, the driving connecting member 1211 is provided with a threaded hole (not labeled in the figure) threadedly sleeved with the screw rod 122 and a sliding groove (not labeled in the figure) slidingly connected with the guide rail 123, one end of the screw rod 122 is formed with or connected with a driving wheel 1221, and the power device 124 can be a rotary motor, the rotary shaft of the rotary motor is directly engaged with the driving wheel 1221 for driving or indirectly drives through an intermediate transmission member (such as a transmission chain).

[0037] In the technical scheme, the horizontal position of the horizontal movement ejector rod 121 can be accurately adjusted by the screw rod 122, and the self-locking ability of the threaded connection between the screw rod 122 and the horizontal movement ejector rod 121 can effectively resist the position deviation of the horizontal movement ejector rod 121 caused by the force applied to the limiting member 11 during the falling of the metal-based element stack.

[0038] In some embodiments, the guide rail 123 comprises two guide rails 123, and the two guide rails 123 are respectively arranged on the left and right sides of the screw rod 122, so that the position adjustment of the limiting member 11 is stable.

[0039] Referring to Figure 3 and Figure 4 , the horizontal movement driving assembly further comprises a mounting plate 125, each guide rail 123 is fixedly connected to the side surface of the mounting plate 125, and the screw rod 122 is pivotally connected to the mounting plate 125 through a corresponding support bearing, so that the structure of the horizontal movement driving assembly of the present application is more compact and convenient to assemble.

[0040] In some embodiments, each of the limiting assemblies further comprises an assembly base 13, which is specifically fixed to the ground or a corresponding fixed platform of the ground, and two vertical beams 131 are arranged at left and right intervals on the assembly base 13, specifically, the two vertical beams 131 are fixed to the top surface of the assembly base 13, each of the limiting assemblies is assembled between the two vertical beams 131, and the height of each of the limiting assemblies can be adjusted along the height direction of the vertical beams 131, and the height adjustment of each of the limiting assemblies can be achieved in a manual adjustment manner, that is, the operator adjusts the height of each of the limiting assemblies adaptively according to the height position of each of the metal base elements to be stacked in the height direction before stacking the metal base elements, so as to ensure that each of the limiting assemblies has a limiting piece 11 corresponding to each of the metal base elements to be stacked in a one-to-one manner, for example, the two sides of the mounting plate 125 of each of the limiting assemblies are respectively formed with a sliding connection structure and a locking pin structure between each of the vertical beams 131, when it is necessary to adjust the height of the limiting assembly, the locking pin in the locking pin structure is pulled out to release the locking of the sliding connection structure, the operator adjusts the limiting assembly up and down along the sliding guide direction of the sliding connection structure to the target position, and then inserts the locking pin again to lock the position of each of the limiting assemblies, which has a simple structure and a low manufacturing cost, of course, other implementation manners can also be adopted under the premise of achieving the foregoing technical purposes of the present application, and the present application does not make special limitation thereto.

[0041] In the technical solution, the height of each of the limiting assemblies can be adjusted, so that the stacking limiting device of the present application can be applied to metal base elements with different thicknesses (heights), which can improve the universality of the stacking limiting device of the present application.

[0042] In some embodiments, the bottom ends of the two vertical beams 131 are fixedly connected (for example, welded) to the top surface of a base top plate 132 of the assembly base 13, and the base top plate 132 can be driven to move linearly and reciprocally along the extension and retraction direction of the transverse top rod 121.

[0043] In the technical solution, the base top plate 132 can be driven to move linearly and reciprocally along the extension and retraction direction of the transverse top rod 121, which can further improve the use range of the stacking limiting device, that is, the stacking limiting of metal base elements with smaller widths or larger widths can be achieved. Specifically, when the width of the metal base element is small, the spacing between the two limiting assemblies opposite to each other can be reduced by adjusting the spacing between the base top plates 132 of each of the limiting assemblies, and vice versa, when the width of the metal base element is large, the spacing between the two limiting assemblies opposite to each other can be increased by adjusting the spacing between the base top plates 132 of each of the limiting assemblies.

[0044] In some embodiments, the assembly base 13 further has a base body 133 with an upwardly open accommodating cavity (not shown or referenced in the drawings), a rotary motor 134 is assembled on the sidewall of the base body 133, the rotating shaft of the rotary motor 134 is drivingly connected with a speed reducer (not shown or referenced in the drawings), and the speed reducer is located in the accommodating cavity, and the output rotating shaft of the speed reducer is used to drive the base top plate 132 to produce linear reciprocating movement, specifically, the base top plate 132 and the top end surface of the base body 133 are slidingly connected through a slide rail assembly, and at the same time, a rack is formed on the bottom side end surface of the base top plate 132, and the gear on the output rotating shaft of the speed reducer is engaged with the rack, so as to achieve driving of the horizontal movement of the base top plate 132.

[0045] In the technical solution, the speed reducer is arranged in the accommodating cavity and the rotary motor 134 is arranged outside the accommodating cavity, so that the compactness of the device can be improved while the volume of the base body 133 is reduced.

[0046] In a specific embodiment, the limiting assemblies are two groups, and the two groups of limiting assemblies are located at opposite sides of the stacking space, so as to objectively achieve accurate limiting of the opposite sides of the metal base units in the stacking falling process. In another more preferred embodiment, four groups of the foregoing limiting assemblies are simultaneously arranged in the same stacking limiting device, and each limiting assembly is arranged in a cross shape around the foregoing stacking space, so as to form balanced and synchronous limiting of four sides of the metal base units, and the stacking accuracy can be further improved.

[0047] According to the embodiments of the present application, a stacking control method using the stacking limiting device is also provided, which comprises the following steps:

[0048] Obtaining a target profile of the side vertical surface of each metal base unit after stacking;

[0049] According to whether the obtained target profile includes a profile segment gradually expanding from top to bottom, the limiting members 11 of each limiting assembly are controlled to move to target positions in sequence or synchronously, so as to ensure that the abutting surfaces of the limiting members 11 can limit the side vertical wall of the falling metal base unit.

[0050] Specifically, when the target profile includes a profile segment gradually expanding from top to bottom, the limiting members 11 located below are controlled to move to the corresponding target positions first, and then the limiting members 11 located above are controlled to move to the corresponding target positions after the corresponding metal base unit is stacked in place, and the process is sequentially performed from top to bottom until all the metal base units are stacked, for example, the target profile is a horn-shaped (frustum type, cone type, etc.), dumbbell or hourglass shape (i.e., the shape of small in the middle and large at both ends, such as Figure 2When the target profile includes a gradually expanding profile segment from top to bottom (i.e. the target profile is a circular cone, a square cone, an inverted circular truncated cone or a truncated cone), the metal base elements are sequentially positioned from bottom to top, that is, after the positioning of the metal base elements of the lower layer is completed, the metal base elements of the upper layer are placed, at this time, the corresponding limiting piece 11 of the layer is first moved to the position and then the metal base elements are placed, and the same is repeated; when the target profile does not include a gradually expanding profile segment from top to bottom (i.e. the target profile is a cylindrical, square cylindrical, inverted circular truncated cone or truncated cone), the limiting pieces 11 are controlled to be synchronously moved to the corresponding target positions, and then the metal base elements are sequentially stacked until the stacking is completed.

[0051] In some embodiments, before the limiting pieces 11 of the limiting assemblies are sequentially or synchronously moved to the target positions, the following steps are further included:

[0052] The heights of the metal base elements to be stacked from bottom to top are obtained, and the heights of the limiting pieces 11 are adjusted to positions corresponding to the metal base elements one by one. As described above, in order to simplify the structure design and reduce the manufacturing cost, the manual adjustment method can be used, at this time, the operator can adjust the height of each limiting assembly according to the height of each layer of metal base elements to ensure that each limiting piece 11 can effectively limit each metal base element.

[0053] It is easy for those skilled in the art to understand that the advantageous technical features of the above-mentioned methods can be freely combined and superimposed without conflict.
