Description
Technical Field
[0001] The utility model relates to the technical field of shelves, in particular to adjustable shelves. Background Art
[0002] The statements herein only provide the background art related to the present invention and do not necessarily constitute the prior art.
[0003] In the field of rail transit equipment manufacturing, such as in production workshops and maintenance depots, workpiece storage racks are essential station tools for orderly storing large and precision parts such as bogies, gearboxes, traction motors, and axle wheels. These workpieces usually have the characteristics of heavy weight, high value, irregular shape, and need to prevent bumping.
[0004] At present, traditional racks mostly adopt rigid structures fixed by welding or bolts. The height of the shelves and the size of the racks are fixed after manufacturing and can only be adapted to a single workpiece. Moreover, for medium and large workpieces stored in the middle position of the rack, the access under the existing technology mainly depends on bridge cranes or large forklifts. Operators need to precisely operate the lifting tools in a narrow space, and the line of sight is easily blocked. It is extremely easy to cause collision and scratching between the workpiece and the rack, and between the workpiece and the workpiece, and the risk is extremely high. Summary of the Utility Model
[0005] The purpose of the utility model is to provide adjustable shelves aiming at the above deficiencies at present.
[0006] To solve the above technical problems, the utility model adopts the following technical solutions: an adjustable shelf, including a rack body and several shelves. The several shelves are vertically stacked on the rack body, and a workpiece storage space is preset between two adjacent shelves. The rack body includes side frames located at the four corners of the several shelves and used for lapping and combining the shelves, and a base provided at the bottom ends of the two side frames and located under the narrow ends of the shelves. Each side frame has a "U-shaped" structure, and a plurality of first holes are uniformly arranged on the side frame along its height direction; The plurality of first holes are arranged horizontally on the side frame and divided into two columns for horizontally splicing two shelves on one side frame; A support component, fixed between the two bases on one side and slidably connected to the narrow ends of each shelf, is used to support the shelf on the rack body; An outward expansion component, movably arranged relative to the rack body, is used to increase the longitudinal horizontal movement distance of the shelf.
[0007] Furthermore, the support assembly includes a fixing member disposed between the two bases on one side, and a first fixing hole plate located at both ends of the fixing member. The first fixing hole plate is fixedly connected to the corresponding hole on the adjacent side frame using bolt a. A slide is fixed to the inner side of the top surface of the fixing member, and the narrow end of the shelf is provided with a sliding groove for assembly or separation on the frame corresponding to the position of the slide.
[0008] Furthermore, the expansion assembly includes a base plate that moves on the bases on both sides, upright plates located at the four corners of the base plate, and a cross brace unit that is detachably mounted on the upright plates. Each upright plate is provided with a plurality of holes II evenly arranged along its height direction. The cross brace unit includes a guide rail located between two upright plates on one side and a second fixing hole plate located at both ends of the guide rail. The second fixing hole plate is provided with bolts b that are connected to the holes II.
[0009] Furthermore, the outer ends of the shelf are provided with guide platforms that are adapted to slide with the guide rail, and the two upright plates on the rear side are provided with slots that are adapted to slide with the guide platforms.
[0010] Furthermore, the fastener is provided with an opening for the vertical plate to pass through at the rear position.
[0011] Furthermore, the base is provided with symmetrical guide grooves of the same structure on the left and right sides, and the bottom of the base plate is provided with guide blocks that can move within the guide grooves at corresponding positions.
[0012] The beneficial effects of this utility model are reflected in: This utility model, through the setting of hole one and the cooperation of the support components, can arbitrarily position the height of the shelf, making it easy to control the layer distance between two adjacent shelves, thereby realizing the adjustability of the frame. Furthermore, by using hole one in two rows on the side frame, two adjacent shelves can be spliced together to adjust the horizontal length of the frame. In addition, through the setting of the expansion component, during the storage and retrieval of medium and large workpieces on the shelf located in the middle position of the frame, the expansion component will move to create a separation space, which extends the longitudinal horizontal distance of the shelf, moving it from inside the frame to outside the frame. This facilitates the use of gripping machinery to grip medium and large workpieces in the created separation space, reducing collisions and scratches between workpieces and the frame, and between workpieces.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0016] Please refer to Figure 1-4 , the present utility model discloses an adjustable shelf, which is applied to the placement of medium and large-sized workpieces, including a frame body and several shelves 1. The several shelves 1 are vertically stacked on the frame body, and a workpiece storage space is preset between two adjacent shelves 1. The frame body includes side frames 2 located at the four corners of the several shelves 1 and used for lapping and combining the shelves 1, and a base 3 provided at the bottom ends of the two side frames 2 and located below the narrow ends of the shelves 1. Each side frame 2 has a "U-shaped" structure, and a plurality of first hole positions 4 are uniformly arranged along the height direction of the side frame 2; The plurality of first hole positions 4 are arranged horizontally on the side frame 2 and divided into two columns, for horizontally splicing two shelves 1 on one side frame 2; A support component 5, fixed between the two bases 3 on one side and slidably connected to the narrow ends of each shelf 1, for supporting the shelf 1 on the frame body; An outer expansion component 6, movably arranged relative to the frame body, for increasing the longitudinal horizontal movement distance of the shelf 1.
[0017] In specific implementation, the side frames 2 distributed at the four corners of the shelf 1 and the base 3 welded to the bottom of the two adjacent side frames 2 at the narrow end are included in the frame. The support assembly 5 is used to open multiple holes 4 along the height direction on the side frames 2 to support and position the shelf 1, so as to control the layer distance between two adjacent shelves 1, thereby realizing the adjustability of the frame. Furthermore, by arranging multiple holes 4 on the side frame 2 into two rows, two shelves 1 can be horizontally spliced on one side frame 2, allowing the horizontal length of the frame to be increased or decreased, which is suitable for actual storage needs and has the advantage of strong applicability. The external expansion component 6, which is installed relative to the frame, can move to create a separation space during the storage and retrieval of medium and large workpieces on the shelf 1 located in the middle position on the frame. This extends the longitudinal horizontal distance of the shelf 1, allowing it to move from inside the frame to outside the frame. This facilitates the use of gripping machinery to grasp medium and large workpieces within the created separation space, and is not limited to the storage and retrieval of medium and large workpieces on a single shelf 1, making operation convenient.
[0018] It should be noted that each shelf 1 is equipped with an electric push rod structure for driving the shelf 1 to move horizontally in and out. This is a linear actuator that integrates a motor, gearbox, and lead screw. The motor rotates, and the gearbox reduces speed and increases torque, driving the lead screw nut to move linearly. The lead screw has a self-locking characteristic and can reliably maintain its position after power failure, ensuring high safety.
[0019] Additional information: Side frame 2 is made of C-shaped steel processed from high-strength structural steel, which has the characteristics of high strength and good load-bearing capacity.
[0020] In one embodiment, the support assembly 5 includes a fixing member 51 disposed between two bases 3 on one side, and first fixing plate 52 located at both ends of the fixing member 51. The first fixing plate 52 is fixedly connected to the corresponding hole 4 opened on the adjacent side frame 2 using bolts a. A slide 53 is fixed to the inner side of the top surface of the fixing member 51, and the narrow end of the shelf 1 is provided with a groove 11 for assembly or disassembly on the frame body at the position corresponding to the slide 53. With this design, the fixing member 51 is fixed to the hole 4 on the two bases 3 on one side at the same horizontal line by means of the fixing member 51 and the first fixing plate 52 welded to both ends of the fixing member 51, and the bolts a. This makes the two bases 3 on one side connected into an integral structure by the fixing member 51, which increases the support strength of the side of the frame body and effectively supports the shelf 1 placed on the frame body. The slide 53 welded to the inner side of the top surface of the fixing member 51 and the corresponding slide groove 11 opened on the narrow end of the shelf 1, through the adaptive sliding of the slide 53 in the slide groove 11, can directly separate the shelf 1 from the frame, and improve production efficiency by cooperating with the automated transfer of workpieces.
[0021] In one embodiment, the expansion assembly 6 includes a base plate 61 movable on the bases 3 on both sides, upright plates 62 disposed at the four corners of the base plate 61, and a cross bracing unit 63 detachably disposed on the upright plates 62. Each upright plate 62 is provided with a plurality of holes 64 evenly arranged along its height direction. The cross bracing unit 63 includes a guide rail 631 located between two upright plates 62 on one side, and a second fixing hole plate 632 located at both ends of the guide rail 631. The second fixing hole plate 632 is provided with bolts b connected to the holes 64. This design, through the corresponding movable base plates 61 on the two side bases 3, and the upright plates 62 welded at the four corners of the base plates 61, utilizes multiple holes 64 evenly opened along the height direction on the upright plates 62, and uses the second fixing hole plates 632 welded to both ends of the guide rail 631, in conjunction with bolts b, to fix the guide rail 631 between the two upright plates 62 on one side, forming an expansion component 6, which can create a separation space at the front of the frame, facilitating the later gripping operation of workpieces on any shelf 1.
[0022] Additional information: The upright plate 62 is made of I-shaped steel processed from high-strength structural steel, which has the characteristics of high strength and good load-bearing capacity.
[0023] In one embodiment, guide platforms 12 adapted to slide along the guide rail 631 are provided at both outer ends of the shelf 1, and slots 621 adapted to slide along the guide platforms 12 are provided on the two rear upright plates 62. This design allows the shelf 1 to slide longitudinally within the extended outer assembly 6 by utilizing the adaptability of the guide rail 631 and the guide platforms 12 during the horizontal movement of the shelf 1, thanks to the guide platforms 12 welded to both outer ends of the shelf 1. Furthermore, slots 621 are opened on the two rear uprights 62 at the corresponding positions of the guides 12. The guides 12 are fitted through the slots 621 in a relatively adaptive manner, without interfering with the secondary movement of the shelf 1 within the expansion assembly 6.
[0024] In one embodiment, the fixing member 51 is provided with a through opening 511 for the upright plate 62 to pass through at the rear position. With this design, the upright plate 62 can move within the through opening 511 during the movement of the expansion component 6 by machining the through opening 511, so as not to interfere with or affect the movement operation of the expansion component 6.
[0025] In one embodiment, the base 3 has symmetrically arranged guide grooves 7 with the same structure on both sides, and the bottom of the base plate 61 has guide blocks that move within the guide grooves 7 at corresponding positions. This design, by using two symmetrically arranged guide grooves 7 on the base 3 and guide blocks welded to the bottom of the base plate 61, allows the guide blocks to move within the corresponding guide grooves 7, thus confining the expansion component 6 to the frame and preventing it from completely detaching from the frame. This facilitates the creation of a separation space at the front of the frame for effectively gripping workpieces on a shelf 1 of a certain layer.
[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0027] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
