Description

An airbag-driven turret lifting structure Technical Field

[0001] This utility model relates to the technical field of heavy-duty turret lifting mechanisms, and in particular to an airbag-driven turret lifting structure. Background Technology

[0002] In heavy-duty turret slewing mechanisms, the turret lifting mechanism is the core component for achieving workstation switching. Currently, most traditional turret lifting devices use hydraulic cylinders, electric screws, or pneumatic cylinders for driving. However, traditional turret lifting devices have many problems:

[0003] While hydraulic cylinder drives have a large load-bearing capacity, hydraulic oil is prone to leakage, polluting the environment. The sealing elements of hydraulic pipelines are also prone to aging and failure. Hydraulic stations are also large and noisy. Electric screw drives have high positioning accuracy, but poor buffering performance during lifting and lowering, large impact during starting and stopping, and can easily cause jamming and wear if there is uneven load. Pneumatic cylinder drives have a simple structure, but the cylinder output force is limited, making it difficult to meet the requirements of heavy load and smooth operation. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model discloses an airbag-driven turret lifting structure.

[0005] The specific technical solution is as follows:

[0006] An airbag-driven turret lifting structure includes an outer sliding sleeve, a supporting sliding sleeve, a guide shaft, an airbag driving assembly, and a supporting base. The turret body achieves rotational movement through the supporting sliding sleeve and the outer sliding sleeve. The airbag driving assembly drives the outer sliding sleeve to move up and down along the supporting sliding sleeve by inflating and deflating, thereby realizing the rotation and lifting of the turret body.

[0007] The airbag drive assembly includes an airbag, a top plate, and a bottom plate. The airbag is installed between the support base and the turret body. The upper end of the airbag is connected to the guide shaft, and the lower end of the airbag is fixed to the support base. The airbag is connected to an external air source to realize inflation and deflation.

[0008] The airbag is equipped with a pressure regulating valve, a solenoid valve, and a one-way valve between itself and the external air source.

[0009] The pressure regulating valve, solenoid valve, and check valve are linked with the PLC.

[0010] Compared with the prior art, the present invention has the following beneficial technical effects:

[0011] This utility model addresses the shortcomings of existing technologies, such as poor buffering performance, uneven load distribution, easy jamming, environmental pollution, and unstable operation. It discloses an airbag-driven turret lifting structure that uses an airbag as a flexible lifting actuator and compressed air as a power source. The vertical lifting motion of the heavy-duty turret is achieved by inflating and deflating the airbag. This structure provides stable lifting, leveling, resistance to uneven load distribution, low impact, and is clean and environmentally friendly, improving the reliability and service life of the turret. It represents a heavy-duty lifting equipment technology that integrates mechanical engineering and pneumatics. Specific advantages are as follows:

[0012] (1) Flexible drive with good buffering and vibration reduction effect. The airbag is a flexible element, and there is no rigid impact during the lifting process. The start and stop are smooth, which reduces the vibration and noise of the turret and improves the operational stability;

[0013] (2) Simple structure, low failure rate and low maintenance. No hydraulic oil, no lead screw and nut, no complex transmission parts, lifting is achieved by inflating and deflating airbags, reliable sealing, low wear, and extremely low maintenance cost;

[0014] (3) Clean and environmentally friendly, suitable for harsh environments. Powered by compressed air, it has no leakage pollution, is resistant to high temperature, dust and moisture, and can work stably in harsh working conditions such as metallurgy, casting and chemical industry;

[0015] (4) Simple control and easy to automate. Lifting, pressure holding, slow descent and synchronous control can be achieved through pneumatic valve group, which is easy to link with PLC to realize automation and remote control. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the accompanying drawings.

[0021] Figure 1 is a three-dimensional structural diagram of the lifting structure of this utility model, Figure 2 is a schematic diagram of the airbag connection of this utility model, and Figure 3 is a three-dimensional structural diagram of the airbag of this utility model, as shown in the figures:

[0022] This utility model relates to an airbag-driven turret lifting structure, comprising an outer sliding sleeve 1, a supporting sliding sleeve 2, a guide shaft 3, an airbag drive assembly 4, and a support base 5. The turret body achieves rotational movement through the supporting sliding sleeve 2 and the outer sliding sleeve 1. The airbag drive assembly 4, through inflation and deflation, drives the outer sliding sleeve 1 to move up and down along the supporting sliding sleeve 2, thereby realizing the rotation and lifting of the turret body. The airbag drive assembly 4 includes an airbag 41, a top plate 42, and a bottom plate 43. The airbag 41 is installed between the support base 5 and the turret body. The upper end of the airbag 41 is connected to the guide shaft 3, and the lower end of the airbag 41 is fixed to the support base 5. The airbag 41 is connected to an external air source to achieve inflation and deflation. The guide shaft 3 and the supporting sliding sleeve 2 limit radial offset and torsion during the turret lifting process, ensuring coaxiality and stability during lifting. A pressure regulating valve, a solenoid valve, and a one-way valve are provided between the airbag 41 and the external air source to achieve lifting speed adjustment, position holding, and self-locking in case of pressure loss. Pressure regulating valves, solenoid valves, and check valves are linked with the PLC to achieve automation and remote control.

[0023] During operation, the ascent process is as follows: The system is powered on, and an external air source supplies air. At this time, the airbag 41 in the airbag drive assembly 4 is in a contracted state, and the turret lifting mechanism is at its lowest position. When the ascent signal is triggered, the system switches to the inflation position, compressed air enters the airbag 41, and the airbag 41 inflates evenly, pushing the guide shaft 3 upward. The guide shaft 3 drives the outer sliding sleeve 1 to rise vertically along the support sliding sleeve 2 until the airbag 41 contacts the top plate 42, and the turret reaches its highest position. After the turret reaches its highest position, it is manually rotated to the desired work position. Once in position, the turret begins to descend.

[0024] Descent process: When the descent signal is triggered, the solenoid valve switches to the exhaust position, the air in the air bag 41 is slowly discharged, and the turret descends smoothly under the weight of the load until the turret is in place and stops at the working position, and the process operation of this station begins.
