[0024] The present utility model provides the following description with reference to the accompanying drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to facilitate understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.
[0025] In the description of the present utility model, when it comes to orientation description, for example, the orientations or positional relationships indicated by up, down, front, back, left, right, etc. are based on the orientations or positional relationships shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0026] It should be understood that when an element (e.g., the first element) is "connected" to another element (e.g., the second element), the element can be directly connected to the other element, or there can be an intermediate element (e.g., the third element) between the element and the other element.
[0027] Embodiments of the present utility model provide a safety limit mechanism for a stacker, including:
[0028] A stacker frame 100, on which a bearing support 200 is provided;
[0029] A safety limit mechanism body 300, the safety limit mechanism body 300 includes a limiting element 310 for blocking the movement of the bearing support 200. The limiting element 310 has a first surface 3110 that abuts against the side wall in the force-bearing direction of the bearing support 200 and a second surface 3112 for connection and fixation.
[0030] The safety limit mechanism body 300 includes a limiting element 310 for blocking the movement of the bearing support 200. The limiting element 310 can be a limiting block, a limiting rod or other forms of mechanical obstacles. The limiting element 310 can effectively prevent the unexpected movement of the bearing support 200.
[0031] It can be understood that when the stacker is carrying goods, the bearing support 200 has a tendency to move in the force-bearing direction, which is the unexpected movement direction of the bearing support 200.
[0032] The limiting element 310 has two main surfaces, namely the first surface 3110 and the second surface 3112. The first surface 3110 abuts against the side wall of the bearing support 200 in the force direction to directly limit the movement of the bearing support 200. The second surface 3112 is used for connection and fixation to ensure the stability and position accuracy of the limiting element 310 on the rack. The connection position can be selected at positions such as the stacker rack 100 and the side wall of the stacker that can be firmly fixed. The safety limiting mechanism body 300 of the present utility model can effectively prevent the bearing support 200 from displacing when carrying overweight goods, improving the safety of the stacker. The limiting element 310 can be fixed to the rack by means such as bolts, welding or fixtures. The choice of connection method needs to consider the convenience of installation, reliability and simplicity of maintenance.
[0033] In some embodiments, the second surface 3112 is fixedly connected to the stacker rack 100.
[0034] The second surface 3112 is the connection interface between the limiting element 310 and the stacker rack 100. It can be fixedly connected to the rack in various ways, such as using bolts, screws, welding or special fixtures. The choice of which fixing method depends on the materials, structures of the rack and the limiting element 310, as well as the required connection strength. In order to prevent the fixed connection from loosening during the long-term operation of the stacker or in a vibrating environment, some anti-loosening measures can be taken, such as using lock nuts, spring washers or adhesives.
[0035] In some embodiments, the limiting element 310 includes a blocking member 3113 and a fixing member 3114. The blocking member 3113 is connected to the fixing member 3114. The blocking member 3113 is provided with the first surface 3110, and the fixing member 3114 is provided with the second surface 3112.
[0036] The blocking member 3113 is a component that directly contacts the bearing support 200 and limits its movement. It can be designed into various shapes, such as a flat plate, an L shape or a T shape, to adapt to different installation requirements and space limitations. The first surface 3110 of the blocking member 3113 is the surface that contacts the bearing support 200 and needs to have sufficient hardness and wear resistance. The function of the fixing member 3114 is to fix the blocking member 3113 in place to ensure its stability and accuracy on the stacker rack 100. The fixing member 3114 can be designed in the form of a bracket, a fixture or a base, etc. The second surface 3112 of the fixing member 3114 is the surface that is connected to the stacker rack 100. This surface needs to be designed into a shape that can closely fit with the rack to ensure the stability of the fixing member 3114. The blocking member 3113 can be fixed to the fixing member 3114 by means such as bolts, screws, welding or snap fasteners. The choice of connection method should consider the simplicity of installation, the firmness of connection and the convenience of maintenance.
[0037] Further, the fixing member 3114 is provided with a positioning portion 3115 through which the blocking member 3113 passes.
[0038] The positioning portion 3115 on the fixing member 3114 is used to accommodate the blocking member 3113. The positioning portion can be circular, square, rectangular or other shapes, depending on the size and shape of the blocking member 3113. The blocking member 3113 passes through the positioning portion 3115, and it can be directly inserted or connected to the fixing member 3114 through a connecting element (such as a pin, a bolt, etc.). This passing method allows the blocking member 3113 to be adjusted within a certain range on the fixing member 3114.
[0039] Further, the fixing member 3114 is fixed on the stacker rack 100.
[0040] In some embodiments, the blocking member 3113 is a limiting rod 3116, and the head of the limiting rod 3116 abuts against the side wall of the bearing support 200 in the force-receiving direction.
[0041] The limiting rod 3116 serves as the blocking member 3113 and is usually made of a strong and durable material such as steel or high-strength plastic. The shape and size of the limiting rod 3116 should be determined according to the size of the bearing support 200 and the required limiting force. The head of the limiting rod 3116 is the part that contacts the bearing support 200 and is designed to tightly abut against the side wall of the bearing support 200 in the force-receiving direction. The shape of the head can be a flat surface, a curved surface or other suitable shapes to ensure good contact with the side wall of the bearing support 200. The design of the head of the limiting rod 3116 should ensure that sufficient resistance can be provided when contacting the bearing support 200 while avoiding damage to the bearing support 200. It may be necessary to add wear-resistant materials or coatings to the head to improve durability. The limiting rod 3116 is fixed in place through the positioning portion 3115 on the fixing member 3114. The limiting rod 3116 can be designed to be adjustable to adapt to bearing supports 200 of different widths or different installation positions. The limiting rod 3116 may need to be finely adjusted according to the actual situation to ensure that its head correctly abuts against the side wall of the bearing support 200. This can be achieved through threads, slide rails or other adjustment mechanisms.
[0042] Further, the limiting rod 3116 is threadedly connected to the fixing member 3114.
[0043] The connection between the limit rod 3116 and the fixing member 3114 adopts a threaded form, which allows the limit rod 3116 to be precisely adjusted axially on the fixing member 3114. The thread can be a standard internal and external thread, or a special thread can be customized according to needs. One end of the limit rod 3116 is designed with an external thread to facilitate matching with the internal thread of the fixing member 3114. This design enables the limit rod 3116 to be easily screwed into or out of the fixing member 3114 to achieve position adjustment. The fixing member 3114 is designed with an internal threaded hole that matches the external thread of the limit rod 3116. By rotating the limit rod 3116, the operator can adjust the contact position of its head with the side wall of the bearing support 200 to adapt to bearing supports 200 of different widths or positions. To prevent the limit rod 3116 from loosening during the operation of the stacker, locking mechanisms such as nuts, lock nuts or locking adhesives can be used at the threaded connection. Considering that vibration and shock may cause the threaded connection to loosen, anti-loosening measures such as spring washers and double nuts can be adopted.
[0044] Furthermore, the limit rod 3116 is a bolt 3117.
[0045] In some embodiments, the limit element 310 further includes a fastening mechanism 3118 that tightly connects the blocking member 3113 and the fixing member 3114.
[0046] The main function of the fastening mechanism 3118 is to ensure that the connection between the blocking member 3113 and the fixing member 3114 is both firm and stable, preventing loosening or displacement during the operation of the stacker. The fastening mechanism 3118 can adopt various types, including but not limited to screws, bolts, nuts, buckles, wedges, shrink fits or quick fastening systems, etc. According to the type of the fastening mechanism 3118, different fastening methods can be adopted, such as threaded fastening, snap connection, wedge fixing or quick fastening, etc.
[0047] In some embodiments, the fastening mechanism 3118 is a nut that is screwed onto the blocking member 3113 to prevent the blocking member 3113 from passing through the fixing member 3114.
[0048] In some embodiments, the limit element 310 is integrally formed.
[0049] The integrally formed limit element 310 has no welded or spliced seams, which can reduce potential weaknesses and improve the overall strength and durability of the component. Integral forming reduces the assembly steps, can improve production efficiency and reduce manufacturing costs.
