Abstract
Description
Technical Field
[0001] The invention relates to the technical field of lifting equipment, and in particular to a novel lifting structure. Background Art
[0002] Lifting devices are basic components of modern mechanical equipment and are widely used in industrial production, automated production lines, logistics and warehousing industries, construction and other fields.
[0003] The most common lifting device is the cylinder, but the cylinder is limited by materials, processes, etc., and the volume of the cylinder is limited. The manufacture of super-large cylinders requires a large amount of high-quality materials, such as high-strength aluminum alloy, stainless steel, etc. The material cost is high, and its processing is difficult, and the processing equipment and process requirements are high, and the manufacturing cost also increases accordingly. Due to the large size and weight of the super-large cylinder, large-scale lifting equipment and professional installation tools are required for installation. The installation space and basic bearing capacity must also be considered, and the installation cost should not be underestimated. When the cylinder is used to deal with large-sized products and especially special-shaped products, the shape of the cylinder cannot be designed into a special shape, and it cannot provide stable and uniform attachment pressure. When providing pressure, the traditional cylinder transmits the pressure point to the surface. When the size is large, uneven pressure will occur. Excessive pressure at a certain point of the product will damage the product. In addition, the piston and cylinder of the super-large cylinder are large in size, and it is difficult to ensure high-precision matching during processing and assembly. In the process of operation, due to factors such as thermal expansion and stress deformation of components, the accuracy will be further affected, and it is difficult to achieve high-precision position control and motion trajectory control. Summary of the invention
[0004] The purpose of the present invention is to provide a new lifting structure to solve the problems mentioned in the above background technology that the existing cylinder is limited in size, difficult to control the precision, and cannot realize complex and special shapes.

[0007] Preferably, an adjustment component is also installed between the upper chamber and the lower chamber.
[0008] Preferably, the adjustment assembly includes connecting ears, connecting heads and adjusting bolts. Multiple connecting ears are evenly fixed on the sides of the upper chamber and the lower chamber. A connecting head is fixed on one side of the connecting ears. The two connecting heads located at corresponding upper and lower positions are fixedly connected by an adjusting bolt.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0022] Example 1
[0023] Reference Figure 1-3 A new type of lifting structure, a new type of lifting structure, includes an upper chamber 1, and a lower chamber 2 arranged at the bottom of the upper chamber 1, a chamber inlet and exhaust pipe 3 is fixed on the top of the upper chamber 1, a matching groove 10 is opened on the side where the upper chamber 1 and the lower chamber 2 are close to each other, a sealing ring 5 is arranged on the inner side of the matching groove 10, a sealing ring inlet and exhaust pipe 4 is fixed at the top of the upper chamber 1 and at a position corresponding to the sealing ring 5, and the bottom of the sealing ring inlet and exhaust pipe 4 is connected to the inner side of the sealing ring 5. The present invention has wide applicability, can be designed in multiple forms, and is suitable for contact with various forms and interfaces, including objects of irregular and complex shapes, without load restrictions, environmental protection, and efficient recycling. At the same time, it can be designed to be very compact, not limited by space and load, and can provide a large force output in a limited space.
[0024] The chamber inlet and exhaust pipe 3 and the sealing ring inlet and exhaust pipe 4 are both connected to an air source, and compressed air enters the chamber inlet and exhaust pipe 3 and the sealing ring inlet and exhaust pipe 4 through an air source such as an air compressor and a pipeline system.
[0025] The upper chamber 1 and the lower chamber 2 are cylindrical, square or special-shaped, which is convenient for designing the device into a lifting device of any special shape.
[0026] Example 2
[0027] Embodiment 1 is further optimized, specifically, as Figure 1 As shown, an adjustment component is also installed between the upper chamber 1 and the lower chamber 2.
[0028] The adjustment component includes connecting ears 6, connecting heads 7 and adjusting bolts 8. Multiple connecting ears 6 are evenly fixed on the sides of the upper chamber 1 and the lower chamber 2. A connecting head 7 is fixed on one side of the connecting ear 6. The two connecting heads 7 located at corresponding upper and lower positions are fixedly connected by an adjusting bolt 8. Through the arrangement of the connecting ears 6, the connecting heads 7 and the adjusting bolts 8, the sealing ring 5 can be protected when the height is adjusted to prevent it from falling off.
[0029] The adjustment assembly also includes a guide rod 9, and a guide rod 9 is installed on the inner side of the two connecting ears 6 located at corresponding upper and lower positions. The top of the guide rod 9 is fixed to the connecting ear 6 located above, and the bottom of the guide rod 9 is slidably connected to the connecting ear 6 located below. Through the setting of the guide rod 9, it can play a guiding role for the upper and lower connections between the connecting ears 6.
[0030] When the present invention is implemented, one main inlet can be used to realize the lifting mode, or other modes can be used, such as multiple gas injection ports, and multiple gas inlets can be designed according to work needs to realize it;
[0031] When the present invention is specifically implemented, the gas injection port can be opened at the bottom, or other opening methods can be used, such as at the top, front, back, etc.
[0032] The air inlets of the upper chamber 1, the lower chamber 2 and the sealing ring 5 can share a common air inlet or can be separated separately.
[0033] From the above, we can know that:
[0034] The implementation process of the above technical solution is:
[0035] First, complete the assembly installation, and use compressed air, i.e., the gas source, to inflate the internal space of the sealing ring 5 through the sealing ring inlet and exhaust pipe 4 to form a sealed chamber. Then, while the sealing ring 5 is inflated, the compressed air enters the upper chamber 1 and the lower chamber 2 through the chamber inlet and exhaust pipe 3. Since the pressure inside the sealing ring 5 is greater than the pressure inside the upper chamber 1 and the lower chamber 2, a closed space is formed. With the injection of gas, the upper chamber 1 rises and converts the pressure energy into mechanical energy.
[0036] Afterwards, the height of the lifting and adjusting component is raised according to the increase in the injection amount to protect the sealing ring 5 to prevent it from falling off. After reaching the required working height, the injection of compressed air is stopped. When exhaust and descent are required, the gas in the upper chamber 1 and the lower chamber 2 is discharged first, and then the high-pressure gas of the sealing ring 5 is discharged to form a working cycle.
[0037] The above embodiment only gives a hexagonal example. The device can be made into a round, square or other arbitrary shapes to adapt to various scenarios; when dealing with large-sized products and especially special-shaped products, the lifting device can be designed into a special shape to provide stable and uniform attachment pressure; the pressure type surface pressure provided by the lifting mechanism of the present invention is evenly distributed at each point on the plane, and can provide uniform pressure when attaching products without damaging the products due to uneven pressure; the present invention is more cost-effective than the cylinder and has a simple design, especially considering installation, maintenance and service life; the present invention does not require the use of oil for lubrication, and this design reduces the risk of environmental pollution caused by oil leakage or disposal. .
