[0027] To make the technical problems solved by the present application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of the present application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0028] In the description of the present application, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] In this application, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0030] The elevator includes a material rack, a lifting mechanism, etc. The material rack is installed on the lifting mechanism. During use, goods are loaded on the material rack, and the driving of the lifting mechanism drives the material rack to lift and lower, thereby achieving the purpose of lifting goods. According to different use scenarios, the structure of the material rack will also be different. In many workshops, elevators are used to lift goods. To facilitate the loading of goods, the material rack is generally set as a bracket structure with a flat top surface and no surrounding obstruction. In this way, it is convenient for the loading and unloading of goods on the material rack, and at the same time, it allows goods larger than the material rack to be placed on the material rack. However, since there is no surrounding wall around the material rack to block the loaded goods, during the lifting process, there is a risk that the loaded goods are likely to slide off the edge of the material rack.

[0031] To overcome the above technical problems, referring to Figures 1-6 , this embodiment provides a material rack 10 of an elevator, including a material rack main body 1 and a vacuum generating unit 2. The material rack main body 1 includes a bottom frame 11 and adsorption rods 12. The bottom frame 11 includes a connected lifting installation part 111 and a load-carrying installation part 112. The lifting installation part 111 is used to connect with the lifting mechanism 20. The adsorption rod 12 has a vacuum chamber inside. The adsorption rod 12 is provided with adsorption holes and vacuum connection holes communicating with the vacuum chamber. The adsorption holes are located on the top surface of the adsorption rod 12. The adsorption rod 12 is fixed on the load-carrying installation part 112. The vacuum generating unit 2 includes a vacuum generator 21 and a solenoid valve 22. Two ends of the solenoid valve 22 are respectively connected to the vacuum generator 21 and the vacuum connection hole through air pipes.

[0032] Specifically, the material rack 10 of this embodiment is installed on the lifting mechanism 20 of the elevator. During use, goods are placed on the adsorption rods 12 of the material rack main body 1. The solenoid valve 22 is opened, and the vacuum generator 21 evacuates the vacuum chamber of the adsorption rod 12 to a negative pressure. After the goods are stabilized, the lifting mechanism 20 is started to run to drive the material rack 10 to lift. After lifting in place, the solenoid valve 22 is disconnected to release the pressure, and then the goods can be taken down.

[0033] The material rack 10 of the elevator based on this embodiment, the material rack 10 includes a material rack main body 1 and a vacuum generating unit 2. An adsorption rod 12 is arranged on the material rack main body 1. A vacuum chamber is provided inside the adsorption rod 12. An adsorption hole and a vacuum connection hole are arranged on the adsorption rod 12. The vacuum generating unit 2 is connected to the vacuum connection hole. When loading goods on the material rack 10, the vacuum generating unit 2 can be used to evacuate the vacuum chamber of the adsorption rod 12 to a negative pressure state. Then, the atmospheric pressure can be used to further press the goods onto the material rack 10, increasing the pressure between the goods and the material rack 10. Furthermore, the static friction force between the goods and the material rack 10 is increased, the stability of the loaded goods is improved, and the risk of the goods falling from the edge of the material rack 10 is reduced.

[0034] In one embodiment, referring to Figure 2 , the load mounting part 112 is connected to one side of the lifting mounting part 111. The load mounting part 112 includes a connecting side 1121 and a free side 1122. The connecting side 1121 is connected to the lifting mounting part 111. The free side 1122 is the side away from the lifting mounting part 111. A plurality of the adsorption rods 12 are arranged in parallel on the load mounting part 112, and the adsorption rods 12 extend along the direction from the connecting side 1121 to the free side 1122. The adsorption holes are arranged at positions on the adsorption rods 12 close to the free side 1122.

[0035] The adsorption rods 12 are arranged in parallel on the load mounting part 112. This layout helps to evenly disperse the weight of the goods and enhance the overall load-bearing capacity of the material rack 10.

[0036] As the side away from the lifting mounting part 111, the free side 1122 provides a wider space for the loading of goods. The free side 1122 facilitates the loading and unloading operations of the goods by the operator, improving work efficiency and convenience. Therefore, the loading and unloading of the goods are generally completed on the free side 1122. After the goods are loaded, they generally approach the edge of the free side 1122. Therefore, the possibility of the goods falling from the material rack 10 basically occurs on the free side 1122. In this solution, the adsorption holes are arranged at positions on the adsorption rods 12 close to the free side 1122. Even when loading goods with a smaller size, it can ensure that the goods can cover the adsorption holes, so as to stably use the atmospheric pressure to press the goods onto the material rack 10, effectively avoiding the problem of the goods falling from the free side 1122.

[0037] In one embodiment, along the length direction of the adsorption rod 12, a plurality of the adsorption holes are arranged at intervals on the adsorption rod 12.

[0038] The arrangement of the plurality of adsorption holes enables the adsorption rod 12 to contact and adsorb multiple points of the goods simultaneously, thereby evenly distributing the adsorption force on the goods and improving the stability of the goods loading.

[0039] In addition, when goods of different shapes and sizes come into contact with the adsorption rod 12, their force application points and contact areas will also be different. By arranging multiple adsorption holes at intervals, the material rack 10 can more flexibly adapt to goods of different shapes and sizes, ensuring a stable adsorption effect in various situations.

[0040] In one embodiment, the vacuum generating unit 2 is installed on the lifting and mounting part 111, and the vacuum connection hole is arranged on the adsorption rod 12 at a position close to the connection side 1121.

[0041] The vacuum generating unit 2 is installed on the lifting and mounting part 111 and can move up and down with the lifting and mounting part 111, thus avoiding problems such as too long connection pipelines between the vacuum generating unit 2 and the adsorption rod 12 and easy breakage of the pipeline winding. The vacuum connection hole is arranged on the adsorption rod 12 at a position close to the connection side 1121, which enables the connected air pipe to be shorter and more directly connected to the adsorption rod 12. This not only simplifies the installation process but also reduces the energy loss and pressure drop caused by too long pipelines.

[0042] In one embodiment, the vacuum connection hole is arranged on the top surface of the adsorption rod 12, and an L-shaped adapter 14 for connecting the air pipe is installed on the vacuum connection hole.

[0043] Arranging the vacuum connection hole on the top surface of the adsorption rod 12 can make more effective use of space. This layout avoids the structural complexity and space limitations that may be brought about by opening connection holes on the side or bottom of the adsorption rod 12. At the same time, the position on the top surface is also convenient for the connection and maintenance of the air pipe. The use of the L-shaped adapter 14 enables the air pipe to be connected to the vacuum connection hole in a more flexible manner, which not only simplifies the installation process but also facilitates subsequent maintenance and repair work. The L-shaped adapter 14 is preferably provided with an external thread, and the vacuum connection hole is provided with an internal thread, and the L-shaped adapter 14 is threadedly installed in the vacuum connection hole.

[0044] To connect the L-shaped adapters 14 on multiple adsorption rods 12 to one solenoid valve 22, a multi-head manifold can be arranged between the L-shaped adapter 14 and the solenoid valve 22. The multi-head manifold has multiple connected joints. The solenoid valve 22 is connected to one of the joints, and each of the remaining L-shaped adapters 14 is respectively connected to a joint through an air pipe, realizing the series connection of the solenoid valve 22 and all the L-shaped adapters 14. In another embodiment, a tee can be connected to each L-shaped adapter 14, and after all the L-shaped adapters 14 are connected in series by using the tees, the tee at the outermost end is connected to the solenoid valve 22.

[0045] In one embodiment, the adsorption rod 12 includes an outer sleeve 121 and a reinforcing core 122 fixed within the outer sleeve 121, and the vacuum chamber is formed between the outer sleeve 121 and the reinforcing core 122.

[0046] The combination of the outer sleeve 121 and the reinforcing core 122 enables the adsorption rod 12 to have higher strength and stability, and can withstand greater loads and impacts, which is particularly important for the material rack 10 that needs to frequently carry heavy objects. By designing the vacuum chamber between the outer sleeve 121 and the reinforcing core 122, the internal space of the adsorption rod 12 is effectively utilized, making the vacuum system more compact and efficient.

[0047] In one embodiment, the vacuum chamber is a through cavity formed within the adsorption rod 12, and sealing plugs 123 are respectively provided at both ends of the adsorption rod 12, and the sealing plugs 123 seal the vacuum chamber from both ends of the adsorption rod 12.

[0048] The vacuum chamber runs through the entire adsorption rod 12 to form a continuous cavity. This design simplifies the structure of the adsorption rod 12 and makes it easier to manufacture by continuous molding methods such as the extrusion process. The extrusion process is an efficient and low-cost processing method, especially suitable for producing long strip-shaped or tubular products. Therefore, the structure of the adsorption rod 12 in this solution can greatly improve production efficiency and reduce production costs. Sealing plugs 123 are respectively provided at both ends of the adsorption rod 12 for sealing the vacuum chamber from both ends. The sealing plugs 123 are usually made of elastic materials such as rubber or silica gel to ensure a tight fit with the inner wall of the adsorption rod 12, thereby achieving a good sealing effect.

[0049] In one embodiment, referring to Figure 3 , an anti-slip gasket 13 is provided on the top surface of the adsorption rod 12, and the anti-slip gasket 13 is provided with avoidance holes 131 corresponding to the adsorption holes.

[0050] The anti-slip gasket 13 is installed on the top surface of the adsorption rod 12, and its main function is to increase the friction force on the contact surface with the goods and prevent the goods from sliding or falling off during transportation or operation. The anti-slip gasket 13 is usually made of materials with a high coefficient of friction, such as rubber, silica gel, or plastics with special textures. Avoidance holes 131 corresponding to the adsorption holes are provided on the anti-slip gasket 13, and the avoidance holes 131 ensure that there are no obstacles blocking the transmission of vacuum and the adsorption effect when the adsorption holes are working.

[0051] In one embodiment, the vacuum generating unit 2 further includes an air storage tank 23, and the air storage tank 23 is connected to the power air source interface of the vacuum generator 21.

[0052] The gas storage tank 23 is an important part of the vacuum generating unit 2. Its main function is to store a certain amount of compressed air or other power gases, which can be quickly released when needed to provide stable and continuous power support for the vacuum generator 21. By using the gas storage tank 23 to store a certain amount of power gases, when the vacuum generator 21 suddenly needs to increase the gas volume or faces air pressure fluctuations, the gas storage tank 23 can quickly release the stored gases to maintain the stability of the system air pressure, which helps to reduce problems such as poor adsorption effect or equipment failure caused by unstable air pressure. Generally, the gas storage tank 23 is connected to the air supply pipeline in the production workshop.

[0053] On the other hand, this embodiment also provides a hoist, which includes a lifting mechanism 20 and the above-mentioned material rack 10. The material rack 10 is connected to the lifting mechanism 20, and the lifting mechanism 20 drives the material rack 10 to lift and lower.

[0054] Based on the material rack 10 of this embodiment, the hoist of this embodiment has the advantages of actively stabilizing the goods and reducing the risk of the goods falling.

[0055] Among them, the lifting mechanism 20 includes a frame 3 and a driving unit 4. A guide rail is provided on the frame 3, and the material rack 10 is slidably installed on the guide rail to guide the lifting and lowering of the material rack 10 by using the guide rail. The driving unit 4 includes a motor and a transmission mechanism. The transmission mechanism includes a first synchronous pulley, a second synchronous pulley and a synchronous belt. The first synchronous pulley is connected to the output shaft of the motor, the second synchronous pulley is installed at the top of the frame 3, the synchronous belt is sleeved on the first synchronous pulley and the second synchronous pulley, and one side of the synchronous belt is fixedly connected to the material rack 10. The motor drives the first synchronous pulley to rotate, and then promotes the synchronous belt to operate, and the operating synchronous belt drives the material rack 10 to lift and lower.
