Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a ground rail guide mechanism for a stacker. Background Art

[0002] Stackers are a crucial type of conveying equipment in logistics warehouses, primarily used for loading and unloading goods. Stackers typically move horizontally along the floor rails and vertically along the columns. Guide wheels are installed on the stacker's upper and lower beams, securing the stacker to the ceiling and floor rails, allowing it to move along the tracks while preventing it from tipping over.

[0003] At present, the guide wheel mechanism on the lower crossbeam of some stackers on the market adopts a conventional guide wheel shaft (non-eccentric shaft), which is completely fixed by nuts. The assembly of this structure relies entirely on the clamping fixation between the nut and the mounting plate, which makes it more difficult to apply force during assembly. At the same time, it is more difficult to adjust the gap between the guide wheel and the track. Moreover, after the stacker has been running continuously for a period of time, the guide wheel mechanism is prone to loosening, the track gap becomes larger, and it is difficult to replace it after damage. Utility Model Content

[0004] The purpose of the utility model is to provide a stacker ground rail guide mechanism with a simple assembly structure, easy disassembly and replacement, more stable operation of the guide wheel mechanism, less prone to loosening, and easier adjustment due to the difficulty in adjusting the gap between the guide wheel and the rail after the stacker has been running continuously for a period of time.

[0005] The technical solution of the utility model is as follows:

[0006] A stacker crane floor rail guide mechanism includes a guide wheel and a support. The guide wheel is provided with a roller bearing and a retaining ring. The guide wheel is passed through an eccentric shaft, and the eccentric shaft is fixed to the support through a tapered clamping sleeve. A fixing nut is provided at the top end of the eccentric shaft, and a shaft sleeve is also provided between the eccentric shaft and the support.

[0007] Furthermore, the tapered clamping sleeve is a T-shaped structure with a tapered hole structure provided inside; the portion where the eccentric shaft and the tapered clamping sleeve cooperate is also a tapered structure, and the tapered structure of the eccentric shaft is adapted to the tapered hole structure of the tapered clamping sleeve.

[0008] Furthermore, the nut is arranged at the top end of the eccentric shaft and is used to clamp the eccentric shaft, the conical clamping sleeve and the support.

[0009] Furthermore, a washer for buffering is provided between the nut and the conical clamping sleeve.

[0010] Furthermore, a bearing hole and a retaining ring hole for mounting a roller bearing and a retaining ring are provided at the center of the guide wheel.

[0011] Furthermore, the support includes an upper support plate and a lower support plate forming an L-shaped structure, and the upper support plate and the lower support plate are welded together; the upper support plate is fixedly connected to the lower crossbeam of the stacker, and the lower support plate is provided with a through hole for installing an eccentric shaft and a conical clamping sleeve.

[0012] Furthermore, the conical clamping sleeve is provided with threaded holes for disassembly.

[0013] Compared with the existing technology, the beneficial effects of the present invention are:

[0014] A stacker crane floor rail guide mechanism adopts the design of eccentric shaft and tapered clamping sleeve, which is simpler to assemble. The tapered clamping sleeve can be rotated by using a nut. The eccentric shaft is completely fixed by the cooperation of the structure of the tapered hole inside the tapered clamping sleeve and the taper of the eccentric shaft body. At the same time, the tapered clamping sleeve can provide a larger anti-rotation torque, making the guide wheel mechanism more stable and less likely to cause the guide wheel to loosen after a long period of operation. When adjusting the gap between the guide wheel and the track, the tapered clamping sleeve can provide a force point, making the gap adjustment and fixation easier. During the disassembly process, a threaded hole of the tapered clamping sleeve can be used to make disassembly simpler and more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0020] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0021] See also Figure 1-3 , a stacker crane ground rail guide mechanism, such as Figure 1 As shown, it includes a guide wheel 1 and a support 6. The guide wheel 1 is provided with a roller bearing 4 and a retaining ring 3. The guide wheel 1 is passed through the eccentric shaft 2, and the eccentric shaft 2 is fixed to the support 6 through a tapered clamping sleeve 7; a fixing nut 9 is provided at the top end of the eccentric shaft 2, and a shaft sleeve 5 is also provided between the eccentric shaft 2 and the support 6.

[0022] like Figure 2 As shown, the tapered clamping sleeve 7 is a T-shaped structure with a tapered hole structure inside. The part where the eccentric shaft 2 and the tapered clamping sleeve 7 fit together is also a tapered structure, and the tapered structure of the eccentric shaft 2 is compatible with the tapered hole structure of the tapered clamping sleeve 7. The outer hole of the tapered clamping sleeve 7 is a through hole, and the inner hole is a tapered structure. The taper matches the taper of the eccentric shaft 2. Its main function is to ensure that the tapered clamping sleeve 7 can firmly fix the eccentric shaft 2 when the nut 9 is turned to screw the tapered clamping sleeve 7 into the lower support plate.

[0023] like Figure 3 As shown, a threaded hole for disassembly is provided on the tapered clamping sleeve 7. During the process of disassembling and replacing the guide wheel mechanism, since the inner hole of the tapered clamping sleeve 7 is tapered, it is difficult to disassemble after screwing it in. During the disassembly process, a bolt is screwed in through this threaded hole and rotated. When the bolt reaches the upper surface of the lower support plate, the bolt is rotated again. Since the bolt has bottomed out and cannot go any further, the reaction force drives the tapered clamping sleeve 7 to move outward, thereby successfully disassembling the guide wheel mechanism, making disassembly and assembly more convenient and labor-saving.

[0024] The nut 9 is arranged on the top end of the eccentric shaft 2 and is used for clamping the eccentric shaft 2, the tapered clamping sleeve 7 and the support 6.

[0025] A washer 8 for buffering is further provided between the nut 9 and the conical clamping sleeve 7 .

[0026] A bearing hole and a retaining ring hole for mounting a roller bearing 4 and a retaining ring 3 are provided at the center of the guide wheel 1 .

[0027] The support 6 includes an upper support plate and a lower support plate forming an L-shaped structure, and the upper support plate and the lower support plate are welded together; the upper support plate is fixedly connected to the lower crossbeam of the stacker, and the lower support plate is provided with a through hole for installing the eccentric shaft 2 and the tapered clamping sleeve 7.

[0028] During installation: After installing the roller bearing 4 and the retaining ring 3 on the guide wheel 1, pass the eccentric shaft 2 through the guide wheel 1, and make the roller bearing 4 and the eccentric shaft 2 tightly connected through the selected tolerance fit, and then pass the sleeve 5 into the eccentric shaft 2 from the top, fit the sleeve 5 and the roller bearing 4 tightly, and then insert the eccentric shaft 2 as a whole into the support 6, and then insert the tapered clamping sleeve 7 and the washer 8 from above the support 6, install the nut 9 and tighten it lightly. At this time, the structure below the support 6 is relatively tight, use the eccentric shaft 2 to move the guide wheel 1 outward, and then rotate the eccentric shaft 2 to adjust the guide wheel 1 to the fully open position (referring to the spacing between the guide wheels 1 on both sides of the track is maximized), and then rotate the eccentric shaft 2 to the appropriate position according to the gap between different tracks to make the gap between the guide wheel 1 and the track suitable, and after completion, rotate the nut 9 so that the nut 9 and the tapered clamping sleeve 7 completely clamp the eccentric shaft 2, and the connection between the tapered clamping sleeve 7 and the eccentric shaft 2 is as shown Figure 2 As shown, the eccentric shaft can be completely fixed through the tapered design, and the guide wheel mechanism is completely adjusted. This method is simple to assemble and adjust, and the guide wheel mechanism is more stable and not easy to loosen.

[0029] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
