Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and more specifically, to a profile shelving unit with support wheels. Background Technology

[0002] Shelving is an important tool for improving efficiency in modern warehouses. There are many types of shelving. When storing profiles, corresponding profile shelving is required. Cantilever profile shelving is one of the most common types.

[0003] Existing cantilever frame racks typically use upright supports with cantilever arms sliding along them. The extension and retraction of the cantilever arms are controlled by gears and racks. Goods are placed on the cantilever arms, and their movement is controlled by the extension and retraction of the arms. During this process, the cantilever arms alone bear the weight of the frame, and their support force is strictly limited. In use, the structure needs to be modified due to varying load-bearing requirements of different frame types. These modifications include changes to the material and specifications to accommodate different load-bearing demands. While this method meets the load-bearing requirements of different frame types, some customers may have goods exceeding the load capacity, making a completely new rack unsuitable in terms of cost and inconvenience. Therefore, we propose a frame rack with support wheels. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a profile rack with support wheels to solve the technical problem that the current cantilever profile rack is not convenient to meet the needs of customers whose goods exceed the load.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a profile rack with support wheels, including a support body and a cantilever frame. The cantilever frame is slidably arranged on each layer on the front and rear sides of the support body. A caster is arranged at the bottom end of the cantilever frame on the bottom layer of the support body. A combined support frame is movably arranged on the two sets of uprights at the top of the cantilever frame. The combined support frame includes a placement plate and an extension frame. The placement plate is movably arranged on the two sets of uprights at the top of the cantilever frame, and the extension frame is movably arranged on the placement plate.

[0006] The top of the extension frame is an upper cavity, inside which several sets of equidistant support gears are rotatably arranged, and the support gears mesh with the rack at the bottom of the cantilever frame.

[0007] Preferably, a fixed bracket is arranged on the top of the support body, a drive shaft is arranged in a rotatable manner on each layer of the support body, a drive frame is arranged on the rear side of the support body, and the drive shaft is connected to the internal transmission structure of the drive frame.

[0008] Preferably, the drive shaft is provided with a drive gear corresponding to the cantilever, and the drive gear meshes with the rack at the bottom of the cantilever.

[0009] Preferably, pin holes are arranged at the top of the two sets of uprights on the cantilever frame, and pins are inserted into both ends of the placement plate.

[0010] Preferably, the top of the placement plate is provided with several sets of equidistant rectangular holes, the bottom of the extension frame is a lower cavity, and the bottom of the lower cavity is provided with support rods corresponding to the rectangular holes. The support rods are inserted into the rectangular holes, and the bottom of the support rods facing the cantilever frame is provided with positioning holes.

[0011] Preferably, the height of the positioning opening is the same as the height of the rectangular hole, the cross-sectional dimensions of the support rod are the same as the cross-sectional dimensions of the rectangular hole, and the lower cavity is inserted into the placement plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features casters installed at one end of the bottom layer of the cantilever frame of the main support structure, and detachable and modular support frames arranged on the two sets of uprights at the top of the cantilever frame. Therefore, when placing profiles, under normal conditions without overloading, personnel can extend the cantilever frame using the gears on the drive shaft in conjunction with the rack at the bottom of the cantilever frame, allowing for normal placement of profiles. If some profiles exceed the load capacity, personnel can extend the bottom layer of the cantilever frame of the main support structure. At this point, the casters on the bottom layer of the cantilever frame support the ground, and the weight that previously had to be borne solely by the cantilever frame is now shared by the cantilever frame and the casters. This significantly increases the load-bearing capacity of the bottom layer of the cantilever frame, enabling storage even in cases of overloaded goods. The loading and unloading of goods still relies on the extension and retraction of the cantilever frames, and the overall structure remains unchanged. If the number of bottom cantilever frames is insufficient, a combined support frame can be installed on the top of the two sets of uprights of the bottom cantilever frames. When the cantilever frame above the bottom layer extends, the combined support frame can support the cantilever frame above the bottom layer, thus enabling it to also hold overloaded goods. This allows for the storage of more overloaded goods without altering the overall structure. Similarly, cantilever frames moving upwards can all be combined and supported by the combined support frame to increase the load-bearing capacity of the cantilever frames and meet the storage needs of overloaded goods. This solves the technical problem that current cantilever profile racks are not suitable for meeting the needs of customers with some goods exceeding the load. Therefore, this utility model has the advantage of meeting the needs of customers with some goods exceeding the load.

[0014] 2. The top of the extension frame in this utility model is an upper cavity, in which several sets of support gears are arranged. When the cantilever extends, the extension frame supports the cantilever through the support gears. Moreover, the support gears can rotate in conjunction with the rack at the bottom of the cantilever. Therefore, after overloaded goods are placed on the cantilever, the cantilever can be stably retracted with the cooperation of the support gears. Furthermore, the cantilever can be stably supported throughout the retraction process until it is completely retracted onto the main body of the support. This can better meet the subsequent retrieval work of overloaded goods stored on the cantilever and further improve the retrieval and placement effect of overloaded goods stored on the cantilever.

[0015] 3. A support rod is provided between the placement plate and the extension frame of this utility model. A positioning hole is opened at the bottom of one side of the support rod, so that the support rod is in a hook shape and the positioning hole faces the cantilever frame. Therefore, when the extension frame is raised, the extension frame is moved directly towards the cantilever frame a certain distance. At this time, the positioning hole of the support rod will be locked in the rectangular hole of the placement plate. Conversely, the extension frame can be quickly reset. In this way, the extension frame can be quickly extended and reset, which is convenient to use. Moreover, because the positioning hole faces the cantilever frame, when the overloaded goods placed on the cantilever frame are recovered, a force in the same direction as the positioning hole will be applied to the extension frame, thereby ensuring that the positioning hole is stably locked in the placement plate, that is, ensuring the stability of the combined support frame in supporting the cantilever frame. Therefore, the combined support frame can more stably support the cantilever frame after loading and recovery. Attached Figure Description

[0023] like Figures 1 to 5 As shown, this utility model relates to a profile rack with supporting wheels, including a support body 1 and a cantilever frame 6. Cantilever frames 6 are slidably arranged on each layer of the front and rear sides of the support body 1. A caster 5 is arranged at one end of the bottom of the cantilever frame 6 on the bottom layer of the support body 1. A combined support frame 7 is movably arranged on two sets of uprights at the top of the cantilever frame 6. The combined support frame 7 includes a placement plate 8 and an extension frame 9. The placement plate 8 is movably arranged on the two sets of uprights at the top of the cantilever frame 6, and the extension frame 9 is movably arranged on the placement plate 8. A fixed bracket 4 is arranged at the top of the support body 1. A drive shaft 2 is rotatably arranged on each layer of the support body 1. A drive frame 3 is arranged on the rear side of the support body 1, and the drive shaft 2 is connected to the internal transmission structure of the drive frame 3. A drive gear corresponding to the cantilever frame 6 is provided on the drive shaft 2, and the drive gear meshes with the rack at the bottom of the cantilever frame 6.

[0024] When placing profile goods, under normal conditions without overloading, personnel can drive the drive shaft 2 to rotate via the drive frame 3. The gear on the drive shaft 2, in conjunction with the rack at the bottom of the cantilever 6, extends the cantilever 6, allowing personnel to place profiles normally on it. If some of the customer's profile goods exceed the load limit, personnel can extend the bottom layer of the cantilever 6 on the main support 1. At this time, the casters 5 on the bottom layer of the cantilever 6 support the ground, and the weight that originally had to be borne by the cantilever 6 alone is now shared by the cantilever 6 and the casters 5. The load-bearing capacity of the bottom layer of the cantilever 6 will increase significantly, which can accommodate some of the overloaded goods. The loading and unloading of goods still rely on the extension and retraction of the cantilever 6, and the overall structure remains unchanged. If the number of bottom cantilever 6 is insufficient, a combined support frame 7 can be installed on the top of the two sets of uprights of the bottom cantilever 6. When the cantilever 6 above the bottom extends, the combined support frame 7 can support the cantilever 6 above the bottom, thus enabling it to also hold overloaded goods and meet the storage needs of more overloaded goods, without changing the overall structure. Similarly, the cantilever 6 going upwards can all be combined and supported by the combined support frame 7 to increase the load-bearing capacity of the cantilever 6 and meet the storage needs of overloaded goods.

[0025] Specifically, pin holes 601 are arranged at the top of the two sets of uprights on the cantilever frame 6, and pins 802 are inserted into both ends of the placement plate 8. When installing the combined support frame 7, the placement plate 8 is directly placed flat on the two sets of uprights of the cantilever frame 6, and then the pins 802 at both ends of the placement plate 8 are inserted into the pin holes 601 of the two sets of uprights on the cantilever frame 6, so that the placement plate 8 is stably placed on the two sets of uprights of the cantilever frame 6.

[0026] In an embodiment of this utility model, the top of the extension frame 9 is an upper cavity 904, and several sets of equidistant support gears 905 are rotatably arranged inside the upper cavity 904, and the support gears 905 mesh with the bottom rack of the cantilever frame 6.

[0027] When the cantilever 6 extends, the extension frame 9 supports the cantilever 6 through the support gear 905. The support gear 905 can rotate in conjunction with the rack at the bottom of the cantilever 6. Therefore, after overloaded goods are placed on the cantilever 6, the cantilever 6 can be stably retracted with the cooperation of the support gear 905. Moreover, the cantilever 6 can be stably supported throughout the retraction process until it is completely retracted onto the support body 1. This can better meet the subsequent retrieval work of overloaded goods stored on the cantilever 6 and further improve the retrieval and placement effect of overloaded goods stored on the cantilever 6.

[0028] In an embodiment of this utility model, the top of the placement plate 8 is provided with several sets of equidistant rectangular holes 801, the bottom of the extension frame 9 is a lower cavity 901, and the bottom of the lower cavity 901 is provided with a support rod 902 corresponding to the rectangular holes 801. The support rod 902 is inserted into the rectangular holes 801, and a positioning port 903 is provided at the bottom of the support rod 902 facing the side of the cantilever frame 6. The height of the positioning port 903 is the same as the height of the rectangular holes 801, and the cross-sectional dimensions of the support rod 902 are the same as the cross-sectional dimensions of the rectangular holes 801. The lower cavity 901 is inserted into the placement plate 8.

[0029] When the extension frame 9 is raised, it is moved directly towards the cantilever frame 6 a certain distance. At this time, the positioning port 903 of the support rod 902 will be locked at the rectangular hole 801 of the placement plate 8. Conversely, the extension frame 9 can be quickly reset. This method can achieve rapid extension and reset of the extension frame 9, which is convenient to use. Moreover, because the positioning port 903 faces the cantilever frame 6, when the overloaded goods on the cantilever frame 6 are recovered, a force in the same direction as the positioning port 903 will be applied to the extension frame 9. This ensures that the positioning port 903 is stably locked on the placement plate 8, which ensures the stability of the combined support frame 7 in supporting the cantilever frame 6. Therefore, the combined support frame 7 can more stably support the cantilever frame 6 after it is loaded and recovered.

[0030] Working Principle: This embodiment provides a profile rack with support wheels. First, when placing profile goods, under normal conditions without overloading, personnel can drive the drive shaft 2 to rotate via the drive frame 3. The gear on the drive shaft 2, in conjunction with the rack at the bottom of the cantilever 6, extends the cantilever 6. Then, personnel can place profiles normally on the cantilever 6. If some of the profile goods exceed the load limit, personnel can extend the bottom layer of the cantilever 6 on the main support body 1. At this time, the casters 5 on the bottom layer of the cantilever 6 support the ground. The weight that originally had to be borne by the cantilever 6 alone is now shared by the cantilever 6 and the casters 5, thus reducing the load capacity of the bottom layer of the cantilever 6. The cantilever structure can be doubled to accommodate some overloaded goods. The entry and exit of goods are still achieved through the extension and retraction of the cantilever 6, and the overall structure remains unchanged. If the number of bottom cantilever 6 is insufficient, a combined support frame 7 can be installed on the top of the two sets of uprights of the bottom cantilever 6. When the cantilever 6 above the bottom extends, the combined support frame 7 can support the cantilever 6 above the bottom, so that it can also hold overloaded goods, thus meeting the storage needs of more overloaded goods, and the overall structure remains unchanged. Similarly, the cantilever 6 going up in sequence can be combined and supported by the combined support frame 7 to increase the load-bearing capacity of the cantilever 6 and meet the storage needs of overloaded goods.

[0031] Secondly, when the cantilever 6 extends, the extension frame 9 supports the cantilever 6 through the support gear 905. Moreover, the support gear 905 can rotate in conjunction with the rack at the bottom of the cantilever 6. Therefore, after overloaded goods are placed on the cantilever 6, the cantilever 6 can be stably retracted with the cooperation of the support gear 905. Furthermore, the cantilever 6 can be stably supported throughout the retraction process until it is completely retracted onto the support body 1. This can better meet the subsequent recovery work of overloaded goods stored on the cantilever 6 and further improve the loading and unloading effect of overloaded goods stored on the cantilever 6.

[0032] Finally, when the extension frame 9 is raised, it is moved directly towards the cantilever frame 6 a certain distance. At this time, the positioning port 903 of the support rod 902 will be locked at the rectangular hole 801 of the placement plate 8. Conversely, the extension frame 9 can be quickly reset. In this way, the extension frame 9 can be quickly extended and reset, which is convenient to use. Moreover, because the positioning port 903 faces the cantilever frame 6, when the overloaded goods on the cantilever frame 6 are recovered, a force in the same direction as the positioning port 903 will be applied to the extension frame 9. This ensures that the positioning port 903 is stably locked on the placement plate 8, which ensures the stability of the combined support frame 7 in supporting the cantilever frame 6. Therefore, the combined support frame 7 can more stably support the cantilever frame 6 after it is loaded and recovered.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
