Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to an adjustable positioning foot specially used for material frame installation. Background Art

[0002] In material handling, materials can be loaded into a material basket and then moved using various automated or semi-automated machines, such as forklifts and AGVs. However, when using automated or semi-automated machinery to move material baskets, conventional baskets lack specialized design features and are not easily transported by forklifts, AGVs, or other similar vehicles. Furthermore, they cannot be directly used with semi-automated or automated conveying equipment.

[0003] The existing conveying industry typically designs a separate support assembly for the material frame to elevate and pad the frame, allowing the forks and brackets at the front of forklifts and AGV guide vehicles to insert into the bottom of the frame. This allows the frame to be lifted vertically and then turned for handling. During this process, the support assembly needs to be installed on the corresponding ground surface, which may have uneven levelness, and there may also be height differences during the support assembly installation process. During the support process, if the support assembly plane does not meet the required levelness, it may affect the subsequent automated or semi-automated handling and conveying operations. Therefore, in the design of automated and semi-automated material frame conveying, the existing problem of horizontal adjustment of the support plane of the material frame support assembly needs to be solved urgently. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the existing technology, the present invention provides an adjustable positioning foot dedicated to a material frame, which can quickly and conveniently adjust the level and height of the supporting plane below the material frame according to installation requirements and load requirements, thereby facilitating subsequent material handling and transportation.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an adjustable positioning foot dedicated to the material frame, which is used to support the material frame base, including a positioning platform base and a round tube welding piece; the positioning platform base is fixed to the installation ground, and the positioning platform base is convexly provided with a round tube-shaped connecting end, the inner wall of the round tube-shaped connecting end has an internal thread, the outer wall of the round tube welding piece has an external thread matching the internal thread, and the round tube welding piece is threadedly connected to the round tube connecting end; the material frame base is arranged on the top of the round tube welding piece.

[0006] In the above scheme, a threaded round tube welded part and a positioning platform base are provided. When the positioning platform base is positioned and fixed, the round tube welded part can be rotated to drive the round tube welded part to move up and down relative to the positioning platform, thereby driving the upper material frame base to rise and fall, thereby realizing the height adjustment and horizontal leveling of the material frame base.

[0007] Furthermore, an adjustment hole is formed through the axial outer wall of the circular tube weldment. When adjusting the thread rotation, a rod-shaped workpiece such as a pin can be inserted through the adjustment hole, forming a handle for rotating the circular tube weldment relative to the positioning platform base, thereby facilitating the thread rotation of the circular tube weldment.

[0008] Furthermore, the positioning platform base is secured to the mounting surface using expansion anchors. The base comprises a fixing plate having a fixing hole formed therein. The fixing plate is secured to the mounting surface using nail-type expansion anchors that engage with the fixing hole.

[0009] Furthermore, to maintain the rotatable and adjustable position of the circular tube weldment after the feed frame base is mounted on it, the feed frame base has a feed frame support rod at the connection position corresponding to the circular tube weldment. A mating mounting platform is also fixed to the top of the circular tube weldment, and the upper surface of the mating mounting platform has a positioning groove that engages the feed frame support rod. The feed frame support rod is rotatably arranged relative to the circular tube weldment to ensure that the circular tube weldment does not interfere with the feed frame base during rotation.

[0010] Furthermore, the material frame support rod is a circular tube with a hollow inner wall, and the mating mounting platform includes a conical protrusion and a mating ring. The bottom of the conical protrusion has an inner groove for the top of the circular tubular connecting end to be inserted and rotated freely. The mating ring is a limited sleeve that fits over the outer circumference of the conical protrusion. The upper end surface of the mating ring protrudes with a limited outer edge. A positioning groove is formed between the limited outer edge of the mating ring and the outer circumference of the conical protrusion. The positioning groove can provide support and limit for the material frame support rod.

[0011] Furthermore, the inner wall of the matching ring is a conical surface that matches the outer peripheral surface of the conical protrusion, and the minimum diameter of the inner wall of the matching ring is smaller than the maximum diameter of the outer peripheral surface of the conical protrusion.

[0012] Furthermore, in order to prevent the upper mating mounting platform from moving downward excessively and causing impact on the positioning platform base during the adjustment of the round tube welded parts, a round nut is fixed on the top of the round tubular connecting end of the positioning platform base, and the outer diameter of the round nut is not less than the maximum outer diameter of the mating ring, that is, the maximum downward stroke of the round tube welded part needs to be limited by the round nut. When the lower end face of the mating mounting platform is pressed against the upper end face of the round nut, it is the maximum downward adjustment stroke position of the round tube welded part.

[0013] The beneficial effect of the present invention is that the present invention provides an adjustable positioning foot dedicated to the material frame, which has a reasonable structural design. Under the premise of stable installation, it can effectively carry the material frame and facilitate subsequent automated and semi-automated conveying operations. It can effectively adjust the height of the corresponding positioning foot, which is convenient for height adjustment and horizontal adjustment of the supporting plane. After carrying the material frame, it can also be adjusted for the second time according to the load requirements. The adjustment process is convenient, fast and reliable.

DETAILED DESCRIPTION

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating the basic structure of the present invention only in a schematic manner. They therefore only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents. Example 1

[0020] like Figure 1 The adjustable positioning foot dedicated to the material frame shown is the first embodiment of the present utility model.

[0021] The first embodiment provides a material frame-specific adjustable positioning foot for supporting the material frame base 1. In this embodiment, the material frame is placed on the material frame base 1, which is a rectangular flat plate structure. Spacers 2 for raising the material frame are spaced apart on the rectangular flat plate structure, and an operating space for the forklift's fork to insert and lift is formed between adjacent spacers 2. At the same time, in order to provide positioning and limiting for the material frame from the circumference of the material frame, material frame support rods 5 are fixed at the four corners of the material frame base 1. The tops of the material frame support rods 5 correspond to the four sides of the lower material frame base 1, and are also connected by upper mounting ribs 4. At the same time, on the side of the non-forklift frame-taking position, diagonally connected lateral mounting ribs 3 are designed to increase the connection strength of the side mounting ribs, the material frame support rods 5 and the material frame base 1.

[0022] On top of this material frame base 1, adjustable positioning feet are installed at the four corners corresponding to the lower bottom surface of the rectangular flat structure. Specifically, each adjustable positioning foot includes a positioning platform base 8 and a round tube weldment 6. The positioning platform base 8 is fixed to the installation ground by an expansion anchor 9. The bottom of the positioning platform base 8 has a fixed flat plate portion 8-2, and the fixed flat plate portion 8-2 is convex with a round tubular connecting end 8-1. Fixed holes are formed on both sides of the fixed flat plate portion 8-2 corresponding to the round tubular connecting end 8-1, and the fixed flat plate portion 8-2 is fixed to the installation ground by a nail-type expansion anchor 9 that is connected to the fixing hole.

[0023] The inner wall of the tubular connecting end 8-1 has internal threads, while the outer wall of the tubular weldment 6 has external threads that mate with these threads. The tubular weldment 6 is threadedly connected to the tubular connecting end 8-1. The material frame support rod 5 of the material frame base 1 is located on top of the tubular weldment 6. When the positioning platform base 8 is positioned and fixed, rotating the tubular weldment 6 causes the tubular weldment 6 to move up and down relative to the positioning platform base 8, thereby raising and lowering the material frame base 1 above, thereby achieving height adjustment and leveling of the four corners of the material frame base 1.

[0024] To facilitate adjustment during the adjustment process of the circular tube weldment 6, an adjustment hole 7 is formed through the axial outer wall of the circular tube weldment 6. When adjusting the thread rotation, a rod-shaped workpiece such as a pin can be inserted through the adjustment hole 7, forming a handle for rotating the circular tube weldment 6 relative to the positioning platform base 8, thereby conveniently driving the circular tube weldment 6 to rotate the thread. Example 2

[0025] like Figure 2 and Figure 3The adjustable positioning foot for a material frame shown is Example 2 of the present utility model. Based on Example 1, Example 2 further specifically designs the upper structure of the circular tube weldment 6 so that while it can effectively position itself with the material frame support rod 5, the threaded rotation of the circular tube weldment 6 will not be interfered with by the material frame support rod 5. This facilitates the height and level adjustment of the positioning foot in four directions after the material frame base 1 is loaded and the material frame is placed on the material frame base 1, further facilitating secondary adjustment of the positioning foot after loading.

[0026] Specifically, a matching mounting platform is fixed on the top of the round tube welding part 6, and the upper surface of the matching mounting platform has a positioning groove for the rotational engagement of the feed frame support rod 5. The feed frame support rod 5 is arranged to rotate relative to the round tube welding part 6 to ensure that the round tube welding part 6 does not interfere with the feed frame base 1 when rotating.

[0027] In the second embodiment, the material frame support rod 5 is a circular tube with a hollow inner wall, and the mating mounting platform includes a conical protrusion 11 and a mating ring 10. The bottom of the conical protrusion 11 has an inner groove for the top of the circular tubular connecting end 8-1 to fit in and rotate freely. The mating ring 10 is a limiting sleeve that fits over the outer circumference of the conical protrusion 11. The inner wall of the mating ring 10 is a conical surface that mates with the outer circumference of the conical protrusion 11, and the minimum diameter of the inner wall of the mating ring 10 is smaller than the maximum diameter of the outer circumference of the conical protrusion 11. The upper end surface of the mating ring 10 protrudes with a limiting outer edge, and a positioning groove is formed between the limiting outer edge of the mating ring 10 and the outer circumference of the conical protrusion 11. This positioning groove not only provides support and positioning for the rotation of the material frame support rod 5, but also prevents the circular tube weldment 6 from interfering with the material frame support rod 5 when the circular tube weldment 6 needs to be adjusted. In actual production assembly, a bearing can be designed at the lower end of the material frame support rod 5 to further maintain the smooth rotation between the positioning groove and the material frame support rod 5, so as to facilitate the height adjustment and horizontal leveling of the positioning foot when carrying materials. Example 3

[0028] like Figure 2 and Figure 3 The adjustable positioning foot for the material frame shown is the third embodiment of the present invention. Based on the second embodiment, the third embodiment further designs the positioning platform base 8 to prevent the upper mating mounting platform from excessively moving downward and causing impact on the positioning platform base 8 during the adjustment of the round tube weldment 6.

[0029] Specifically, a round nut 8-3 is fixed on the top of the circular tubular connecting end 8-1 of the positioning platform base 8, and the outer diameter of the circular nut 8-3 is not less than the maximum outer diameter of the matching ring 10. In this way, the maximum downward stroke of the circular tube weldment 6 will be limited by the circular nut 8-3. When the lower end face of the matching mounting platform is pressed against the upper end face of the circular nut 8-3, this position is the maximum downward stroke position of the circular tube weldment 6, which can effectively avoid the impact on the positioning platform base 8 below during the adjustment process, avoid deformation of the threads in the circular tubular connecting end 8-1 of the positioning platform base 8 caused by the impact, avoid affecting the adjustable performance of the positioning foot, and maintain smooth and controllable height adjustment and horizontal leveling.

[0030] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
