Description

Technical Field

[0001] This application relates to the field of transportation auxiliary equipment technology, and more specifically to a storage and transportation trolley. Background Technology

[0002] The external surfaces of equipment used in semiconductor device manufacturing are typically covered with plate-like covers of varying sizes and thicknesses. These covers often need to be removed during equipment repair and maintenance, requiring sufficient space to store them.

[0003] Currently, there are generally three ways to store the outer cover. The first is to place the outer cover directly on the raised floor for storage, which saves ground area by utilizing vertical space. The second is to stack the outer cover on a flatbed cart, which is convenient for pushing and moving, but may have the problem of unstable storage. The third is to place the outer cover on a trolley with guardrails, which helps to prevent the outer cover from slipping, but the storage space is limited and may cause the outer cover to be piled up messily. If the guardrails are too high, it will also affect the operation of picking up and putting down the outer cover.

[0004] Existing methods of storing outer covers often occupy a lot of space and easily lead to cluttered stacking, increasing management difficulty. At the same time, haphazardly placed outer covers are not only easily damaged, but may also become a hazard that trips over engineers, thereby affecting the maintenance efficiency of the machine and the protective effect of the outer covers.

[0005] Therefore, improvements are needed to at least partially address the aforementioned problems. Utility Model Content

[0006] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] To at least partially solve the above problems, this utility model provides a storage and transport trolley, which includes: A bottom support, wherein the bottom support is horizontally positioned; At least four wheels are located on the underside of the bottom support; A first side bracket and a second side bracket are both vertically mounted on the bottom bracket, and the first side bracket and the second side bracket are parallel and spaced apart. A third side support and a fourth side support are arranged parallel to and spaced between the first side support and the second side support. Each third side support and the fourth side support includes a crossbeam and multiple columns. The two ends of the crossbeam are connected to the first side support and the second side support, respectively. The multiple columns are arranged parallel to and spaced apart, and each column can be detachably inserted into the crossbeam. The lower end of each column abuts against the bottom support. The crossbeam is parallel to the bottom support, and the columns are perpendicular to the bottom support.

[0008] For example, both the third side support and the fourth side support include two horizontal beams arranged in parallel and spaced apart. Each horizontal beam is provided with a plurality of insertion holes corresponding to a plurality of columns. Each column is inserted into the insertion holes on the two horizontal beams.

[0009] For example, both the first side support and the second side support include two parallel and spaced uprights and at least one horizontal bar. The lower end of the upright is fixedly connected to the bottom support and is perpendicular to the bottom support. The two ends of the horizontal bar are respectively connected to the two uprights and are parallel to the bottom support.

[0010] For example, the storage and transport trolley also includes a plurality of handles, each handle including a rod body and a grip handle fixedly connected to the rod body, the rod body being detachably inserted into the upper end of the upright.

[0011] For example, the side wall of the upright is provided with a snap-fit ​​protrusion, and the side wall of the pole body is provided with a snap-fit ​​hole corresponding to the snap-fit ​​protrusion; or, The side wall of the upright is provided with a snap-fit ​​hole, and the side wall of the pole body is provided with a snap-fit ​​protrusion corresponding to the snap-fit ​​hole.

[0012] For example, the storage and transportation trolley also includes a plurality of handles, each handle including a rod body and a grip handle fixedly connected to the rod body, the rod body being rotatably connected to the upper end of the upright, the rotation axis of the rod body being perpendicular to the upright, the handle having a first pin hole, and the upright having a second pin hole corresponding to the first pin hole; The storage and transport trolley also includes pins, which are detachably inserted into the first pin hole and the second pin hole.

[0013] For example, the storage and transport trolley further includes at least one support rod, which is disposed between the first side support and the second side support. The two ends of the support rod are fixedly connected to the crossbar in the first side support and the crossbar in the second side support, respectively. The support rod is parallel to the bottom support, and the upper surface of the support rod is not lower than the uppermost surface of the crossbeam.

[0014] For example, the first side bracket and / or the second side bracket are provided with a column storage slot, which is used to store the column disassembled from the third side bracket and the fourth side bracket.

[0015] For example, the outer side of the column is at least partially covered with a flexible buffer layer.

[0016] For example, a tray is provided on the bottom support.

[0017] According to the storage and transport trolley of this utility model, plate-shaped objects (such as the outer cover of machine equipment) can be stored by utilizing the gap between two adjacent uprights in the third and fourth side supports, achieving neat storage of plate-shaped objects and reducing space occupation. Furthermore, since the uprights are detachably inserted into the crossbeams, the gap between adjacent uprights can be adjusted according to the thickness of the plate-shaped objects (for example, when the plate-shaped objects are thicker, some uprights can be removed to increase the gap between adjacent uprights), thus achieving effective storage of plate-shaped objects of different sizes.

Consequently, the figures are substantially schematic, and their shapes are not intended to show the actual shape of the device and are not intended to limit the scope of this application.

[0026] See attached document Figures 1-4 An exemplary description of a storage and transport trolley according to an embodiment of this application is provided. The storage and transport trolley includes a bottom support 100, at least four wheels 200, a first side support 300, a second side support 400, a third side support 500, and a fourth side support 600.

[0027] The bottom support 100 is horizontally positioned, and at least four wheels 200 are located on the underside of the bottom support 100. This allows the storage and transport trolley to be easily moved using the wheels 200.

[0028] The first side bracket 300 and the second side bracket 400 are both vertically mounted on the bottom bracket 100, and the first side bracket 300 and the second side bracket 400 are arranged parallel to each other at intervals.

[0029] The third side support 500 and the fourth side support 600 are arranged in parallel between the first side support 300 and the second side support 400. Both the third side support 500 and the fourth side support 600 include a crossbeam 510 and multiple columns 520. The two ends of the crossbeam 510 are connected to the first side support 300 and the second side support 400, respectively. The multiple columns 520 are arranged in parallel and spaced apart, and can all be detachably inserted into the crossbeam 510. The lower end of the column 520 abuts against the bottom support 100. The crossbeam 510 is parallel to the bottom support 100, and the column 520 is perpendicular to the bottom support 100.

[0030] According to the embodiment of the application, the storage trolley can utilize the gap between two adjacent uprights 520 in the third side bracket 500 and the fourth side bracket 600 to store plate-shaped objects (such as the outer cover of machine equipment), achieving neat storage of plate-shaped objects and reducing space occupation. Furthermore, since the uprights 520 are detachably inserted into the crossbeam 510, the gap between adjacent uprights 520 can be adjusted according to the thickness of the plate-shaped object (for example, when the plate-shaped object is thicker, some uprights 520 can be removed to increase the gap between adjacent uprights 520), thus achieving effective storage of plate-shaped objects of different sizes.

[0031] For example, see Appendix Figure 1 In this embodiment, the bottom support 100 includes bottom beams 110, 120, 130, and 140, which together form a rectangular frame. The bottom support 100 also includes a connecting beam 150, whose two ends are connected to the bottom beams 120 and 140 respectively. The connecting beam 150 can be used to enhance the structural strength of the bottom frame. The bottom beams 110, 120, 130, 140, and connecting beam 150 are all located on the same plane, which is a horizontal plane. For example, a tray can be provided on the bottom support 100 for storing parts, tools, etc., to improve the practicality of the storage and transport trolley.

[0032] For example, see Appendix Figure 1 In this embodiment, both the third side support 500 and the fourth side support 600 include two parallel and spaced-apart crossbeams 510. The two crossbeams 510 are arranged parallel and spaced-apart in the vertical direction and are adjacent to the bottom support 100 to ensure sufficient space above the crossbeams 510 for placing plate-shaped objects. Each crossbeam 510 is provided with multiple insertion holes corresponding to multiple uprights 520, and each upright 520 is inserted into the insertion holes on the two crossbeams 510. The insertion holes on the two crossbeams 510 effectively limit the movement of the uprights 520, allowing them to move only in the direction of insertion or removal from the insertion holes. This structural design facilitates the disassembly of the uprights 520 and maintains stability after insertion; furthermore, by limiting the movement of the uprights 520 using the two crossbeams 510, the thickness of the crossbeams 510 can be reduced, thereby reducing material costs.

[0033] In some other embodiments, the third side support 500 and the fourth side support 600 may each include a thick crossbeam 510, which may be, for example, a square steel pipe. The crossbeam 510 is provided with a plurality of insertion holes corresponding to a plurality of columns 520, and each column 520 is inserted into the insertion hole on the crossbeam 510.

[0034] For example, see Appendix Figure 1In this embodiment, both the first side support 300 and the second side support 400 include two parallel and spaced uprights 310 and at least one crossbar 320 (two in this embodiment). The lower ends of the uprights 310 are fixedly connected to the bottom support 100 and are perpendicular to the bottom support 100. The two ends of the crossbar 320 are respectively connected to the two uprights 310 and are parallel to the bottom support 100. The two ends of the crossbeam 510 are respectively connected to the uprights 310 in the first side support 300 and the second side support 400. The first side support 300 and the second side support 400 are configured in the above structural form, which gives the trolley high structural strength and facilitates structural stability during the transportation and storage of items.

[0035] For example, see Appendix Figures 1-4 In this embodiment, the storage and transport trolley also includes multiple handle levers 700 (two are shown in the figure, but the number of handle levers 700 can also be four). Each handle lever 700 includes a rod body 710 and a grip handle 720 fixedly connected to the rod body 710. The rod body 710 is detachably inserted into the upper end of the upright post 310. Thus, when the rod body 710 is inserted into the upper end of the upright post 310, the operator can grip the grip handle 720 to push or pull the storage and transport trolley to move it, thereby transporting the items stored on the trolley. Since the handle 700's body 710 is detachably inserted into the upper end of the upright 310, the handle 700 can be removed when the storage trolley does not need to be pushed or pulled, thereby reducing the overall height of the storage trolley. This makes it easier for operators to lift and pull plate-shaped objects up and down near the first side support 300 and the second side support 400 to access them, eliminating the need to drag the plate-shaped objects back and forth near the third side support 500 and the fourth side support 600, effectively preventing surface damage caused by dragging the plate-shaped objects. In this embodiment, the upper end of the upright 310 is provided with a plugging protrusion 312, and the lower end of the handle 700's body 710 is provided with a plugging groove corresponding to the plugging protrusion 312. In some other embodiments, the upper end of the upright 310 may be provided with a plug groove, and the lower end of the handle 700 710 may be provided with a plug protrusion 312 corresponding to the plug groove. Such a configuration can further reduce the overall height of the storage and transportation trolley.

[0036] For example, see Appendix Figure 1 , Figure 2In this embodiment, a snap-fit ​​protrusion 311 is provided on the side wall of the upright 310, and a snap-fit ​​hole (not shown in the figure) corresponding to the snap-fit ​​protrusion 311 is provided on the side wall of the handle 700. Thus, the handle 700, which can be detached from the upper end of the upright 310, can be snapped onto the side wall of the upright 310 through the snap-fit ​​protrusion 311 and the snap-fit ​​hole, conveniently storing the handle 700 and preventing it from being lost. For example, the snap-fit ​​protrusion 311 may include a first cylindrical segment and a second cylindrical segment, which are coaxially arranged, and the diameter of the second cylindrical segment is larger than the diameter of the first cylindrical segment. The first end of the first cylindrical segment is connected to the upright 310, and the second end of the first cylindrical segment is connected to the second cylindrical segment. The snap-fit ​​hole can be a gourd-shaped hole corresponding to the first and second cylindrical segments. In some other embodiments, the side wall of the upright 310 may be provided with a snap-fit ​​hole, and the side wall of the handle 700 710 may be provided with a snap-fit ​​protrusion 311 corresponding to the snap-fit ​​hole.

[0037] In some other embodiments, the storage and transport trolley includes multiple handles 700, each handle 700 including a rod body 710 and a grip handle 720 fixedly connected to the rod body 710. The rod body 710 is rotatably connected to the upper end of a vertical pole 310, and the axis of rotation of the rod body 710 is perpendicular to the vertical pole 310. Exemplarily, the rod body 710 and the vertical pole 310 can be rotatably connected via a hinge or a hole-and-shaft structure. The handle 700 also has a first pin hole, and the vertical pole 310 has a second pin hole corresponding to the first pin hole. The storage and transport trolley also includes pins, which are detachably inserted into the first and second pin holes to limit the rotation of the rod body 710 relative to the vertical pole 310, thus stably holding the rod body 710 at the upper end of the vertical pole 310. When the lever 710 is located at the upper end of the upright 310, and the pin is inserted into the first pin hole and the second pin hole, the operator can hold the handle 720 to push or pull the storage trolley to move the items stored on it. When it is not necessary to push or pull the storage trolley, the pin can be pulled out from the first pin hole and the second pin hole, and the lever 710 of the handle 700 can be rotated to the side of the upright 310 to lower the overall height of the storage trolley, making it easier to store and retrieve items on it.

[0038] For example, see Appendix Figure 1 , Figure 4In this embodiment, the storage and transport trolley further includes at least one support rod 800 (three in this embodiment). The support rod 800 is disposed between the first side support 300 and the second side support 400. Both ends of the support rod 800 are fixedly connected to the crossbars 320 in the first side support 300 and the second side support 400, respectively. The support rod 800 is parallel to the bottom support 100, and its upper surface is not lower than the uppermost surface of the crossbeam 510. Therefore, the plate-shaped objects stored on the storage and transport trolley can be supported solely by the support rod 800, or by the support rod 800 and the crossbeam 510 together. The support rod 800 can be made of high-strength tubing to support heavy objects. In other embodiments, the storage and transport trolley may not have support rods 800, and the plate-shaped objects can be supported entirely by the crossbeam 510.

[0039] For example, see Appendix Figure 1 In this embodiment, the first side support 300 and the second side support 400 are provided with column storage slots 340, which are used to store columns 520 disassembled from the third side support 500 and the fourth side support 600. See attached figure for an example. Figure 4 The first side support 300 and the second side support 400 both include two parallel and spaced horizontal bars 320 and a connecting rod 330 connecting the two horizontal bars 320. The connecting rod 330 is parallel to the upright 310, and the distance between the connecting rod 330 and an upright 310 is slightly greater than the length of the upright 520. On the side of the upright 310 facing the connecting rod 330, there are parallel and spaced-apart limiting pieces 341 and 342. The distance between the limiting pieces 341 and 342 is slightly larger than the diameter of the upright 520. On the side of the connecting rod 330 facing the upright 310, there are parallel and spaced-apart limiting pieces 343 and 344. The distance between the limiting pieces 343 and 344 is slightly larger than the diameter of the upright 520. The bottom of the limiting pieces 341, 342, 343 and 344 are all connected to the lower crossbar 320. The top of the limiting pieces 341, 342, 343 and 344 are all at a certain distance from the upper crossbar 320. Thus, a column storage groove 340 is formed between limiting pieces 341 and 342, and between limiting pieces 343 and 344. The column 520 can be placed horizontally in the column storage groove 340. One end of the column 520 is limited between limiting pieces 341 and 342, and the other end is limited between limiting pieces 343 and 344. The column 520 can only move vertically in the column storage groove 340. The column storage groove 340 allows for convenient storage and retrieval of the removed column 520, preventing its loss. In some other embodiments, the column storage groove 340 may be provided only on the first side bracket 300 or the second side bracket 400.

[0040] For example, the outer side of the column 520 is at least partially covered with a flexible buffer layer. Specifically, the portion of the column 520 above the crossbeam 510 may be covered with a flexible buffer layer, which may be a rubber layer, a sponge layer, etc. The flexible buffer layer can cushion the collision between the plate-like object and the column 520, preventing damage to the surface of the plate-like object during storage and retrieval.
