Description

Technical Field

[0001] This invention relates to the field of pneumatic lifting device technology, and in particular to an adjustable air-filled lifting mechanism. Background Technology

[0002] A pneumatic jack, also known as an airbag pneumatic jack, uses compressed air as a power source to lift heavy objects. Compared to mechanical jacks, pneumatic jacks offer advantages such as lower effort, higher efficiency, faster lifting speed, greater lifting force, and improved safety.

[0003] However, most pneumatic jacks currently only support vertical lifting and lack multi-directional adjustment or automation functions, making them unsuitable for complex scenarios. Existing products rarely integrate sensors or IoT technology, making it impossible to monitor parameters such as pressure, displacement, and tilt angle in real time, relying on human experience to assess risks. Summary of the Invention

[0004] The purpose of this invention is to improve the structure of a pneumatic jack, making it intelligent and enabling precise control over the lifting position of an object.

[0005] To achieve the above objectives, the present invention provides an adjustable inflatable lifting mechanism, including a connected lifting component, an air pump, and a controller; The lifting component includes a main airbag and several auxiliary airbags disposed on the upper part of the main airbag, and the object to be lifted is in contact with the auxiliary airbags. The main airbag and the auxiliary airbag are respectively connected to the air pump; The controller is used to control the air pump to supply air to different auxiliary airbags after the main airbag lifts the object, so that the object tilts and lifts.

[0006] Furthermore, the adjustable inflatable lifting mechanism also includes a connector, a main air inlet pipe, and a secondary air inlet pipe; The connector is equipped with a main air inlet, a secondary air inlet, and a check valve. The main airbag and the auxiliary airbag are respectively connected to the air pump through the main air inlet and the auxiliary air inlet.

[0007] Furthermore, the connector is also equipped with a mechanical pressure relief valve.

[0008] Furthermore, the adjustable inflatable lifting mechanism also includes a lifting plate, which is provided with a through-hole structure that matches the auxiliary airbag; The lifting plate is installed on the main airbag to increase the contact area with the object.

[0009] Furthermore, a universal level is also installed on the lifting plate; The universal level can transmit the tilt angle information of the object to the controller.

[0010] Furthermore, the controller is equipped with a display panel and fine-tuning buttons. The display panel is used to display the pressure of the main airbag and the auxiliary airbag, as well as the tilt angle information of the object; Therefore, the fine-tuning button is used to control the air intake and exhaust of the auxiliary airbag according to the tilt angle information of the object, so as to achieve precise control of the object's position.

[0011] Furthermore, the controller is equipped with an inflation switch and a pressure relief switch; The inflation switch and the pressure relief switch are used to control the air pump to inflate the main airbag and to control the main airbag to depressurize, respectively.

[0012] Furthermore, the air pump is integrated into the controller.

[0013] Furthermore, the controller is also provided with an air inlet and an air outlet; The air inlet is connected to compressed air; The air outlet is connected to the main airbag and the auxiliary airbag.

[0014] The present invention also provides the application of the above-mentioned adjustable inflatable lifting mechanism in lifting objects.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The adjustable inflatable lifting mechanism of this invention solves the problem that traditional pneumatic jacks can only lift objects vertically by incorporating an auxiliary airbag, allowing the lifted object to be in a horizontal position or tilted at a certain angle, thus achieving multi-directional control. Furthermore, the invention is relatively thin in its initial uninflated state, making it suitable for lifting objects in confined spaces. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example like Figure 1 and Figure 2As shown, an adjustable inflatable lifting mechanism includes a controller 1 and a lifting component 2 connected together. The controller 1 integrates an air pump. The lifting component 2 includes a main airbag 21, eight auxiliary airbags 22 disposed on the upper part of the main airbag 21, and a lifting plate 3. The lifting plate 3 has through-hole structures matching the auxiliary airbags 22 and is mounted on the main airbag 21 to increase the contact area with the object. The object to be lifted contacts the auxiliary airbags 22 and the lifting plate 3. The main airbag 21 and the auxiliary airbags 22 are respectively connected to the air pump. The controller 1 controls the air pump to supply air to different auxiliary airbags 22 after the main airbag 21 lifts the object 4, causing the object 4 to be lifted at an angle. A universal level 31 is also disposed on the lifting plate 3, which can transmit the tilt angle information of the object 4 to the controller 1.

[0022] Specifically, such as Figure 3 As shown, the adjustable inflatable lifting mechanism includes a connector, a main air inlet pipe 23, and a secondary air inlet pipe 24. The connector is equipped with a main air inlet 251, a secondary air inlet 252, and a check valve 25. The main airbag 21 and the secondary airbag 22 are connected to the air pump via the main air inlet 251 and the main air inlet pipe 23, and the secondary air inlet 252 and the secondary air inlet pipe 24, respectively. When the gas pressure inside the main airbag 21 reaches a limit, the check valve 25 closes the main air inlet 251 and opens the secondary air inlet 252 to inflate the secondary airbag 22. The air pump can inflate all eight secondary airbags 22 simultaneously, ensuring the balance of the lifted object. A mechanical pressure relief valve 26 is also provided at the connector.

[0023] like Figure 4 As shown, the controller 1 is equipped with a display panel 11 and a fine-tuning button 13. The display panel 11 includes a pressure display area 111 and a tilt angle display area 112, which are used to display the pressure of the main airbag 21 and the auxiliary airbag 22, as well as the tilt angle information of the object, respectively. The fine-tuning button 13 is used to control the air intake and exhaust of the auxiliary airbag 22 according to the tilt angle information of the object, controlling the inflation amount of different auxiliary airbags 22 to meet the tilting and lifting requirements of the lifting device, thereby achieving precise control of the tilt angle of the object. The controller 1 is also equipped with an inflation switch 12 and a pressure relief switch 16, which are used to control the air pump to inflate the main airbag 21 and to control the pressure relief of the main airbag 21, respectively. The controller 1 is also equipped with an air inlet 14 and an air outlet 15; the air inlet 14 is connected to compressed air; and the air outlet 15 is connected to the main airbag 21 and the auxiliary airbag 22. After the lifting operation is completed, press the inflation switch 12 in the control area of ​​controller 1 to stop inflation, and then press the pressure relief switch 16 to release pressure and terminate the lifting operation. In case of special circumstances, emergency pressure relief can be performed directly through the mechanical pressure relief valve 26.

[0024] The working process of the adjustable air-lifting mechanism in this embodiment is described in detail below: Preparation phase: The adjustable inflatable lifting mechanism, initially in a non-pressurized state, is precisely positioned below the object to be lifted, ensuring that the lifting plate 3 is completely flush with the lower surface of the object 4 without any gaps. A reliable connection is established between the main airbag 21's air inlet pipe and the controller 1's air outlet, creating a stable air transmission channel.

[0025] System startup and main airbag 21 inflation: Connecting the controller 1 to the system power supply triggers the inflation switch 12, activating the built-in air pump. The air pump inflates the main airbag 21 through the main air intake pipe 23. The high-precision pressure sensor built into the main airbag 21 collects internal air pressure data in real time and transmits the pressure signal to the controller 1 in the form of an electrical signal. The controller 1 displays the processed pressure data dynamically in real time in the air pressure display area 111. When the internal pressure of the main airbag 21 reaches the preset safety limit, the controller 1 drives the check valve 25 to operate based on the pressure signal, closing the main air intake port 251 to block the main air passage, simultaneously opening the auxiliary air intake port 252, and automatically pausing the air pump operation, completing the main airbag 21 inflation stage control.

[0026] Pressure Adjustment and Sub-Airbag 22 Inflation: After the main airbag 21 is inflated, the operator can precisely adjust the pressure inside the airbag using the pressure relief switch 16 according to actual working conditions. If further inflation of the sub-airbag 22 group is required, the air pump can be started to inflate the entire sub-airbag 22. At the same time, the fine-tuning button 13 allows the operator to manually adjust the inflation of the eight independent sub-airbags 22 according to specific needs, in order to meet the requirements of fine pressure control.

[0027] Object attitude monitoring and adjustment: Throughout the lifting operation, the lifting plate 3, as the main load-bearing component, remains in close contact with the object being lifted 4. When the object being lifted 4 tilts due to uneven force, the universal level 31, installed at the geometric center of the lifting plate 3, monitors the change in the object's tilt angle in real time and converts the tilt signal into an electrical signal, which is then transmitted to the controller 1. After processing the signal, the controller 1 displays the object's tilt angle parameters in real time in the tilt angle display area 112. By observing the tilt angle display data, the operator uses the fine-tuning button 13 to precisely control the inflation volume of each auxiliary airbag 22. By adjusting the local airbag pressure, the object's attitude is corrected in real time until the tilt angle display data indicates that the object has reached an ideal balance state, ensuring the lifting operation is carried out safely and stably. Figure 5 As shown, the object 4 is lifted to a certain height on the ground 5.

[0028] In this typical implementation, the main airbag 21 and the auxiliary airbag 22 are made of rubber, which has good elasticity and flexibility, and can adapt to lifting objects of different shapes and sizes. The rated air pressure range of the main airbag 21 is 0.5MPa-1.0MPa, and the diameter of the main airbag 21 is 1m. When the air pressure acts on the effective area of ​​the main airbag 21, it will generate a vertical upward thrust, and the lifting force is directly proportional to the air pressure: Lifting force = Air pressure × Effective force-bearing area of ​​the main airbag 21. According to the formula, the lifting force ranges from 3.9kN to 7.8kN.

[0029] In this typical implementation, the lifting plate 3 is made of aluminum alloy with a compressive strength of over 500 MPa. Furthermore, to ensure proper fixation of the lifting plate 3, the main airbag 21, and the auxiliary airbag 22, they are bonded together using rubber adhesive.

[0030] In summary, the present invention has the following advantages: (1) By finely adjusting the auxiliary airbag, the present invention solves the problem that traditional jacks can only lift objects in the vertical direction, so that the object being lifted is in a horizontal state or maintains a certain angle of inclination, thus achieving multi-directional control. (2) The present invention is thinner in the initial state when it is not inflated, which solves the problem that the traditional jack is heavy and the distance between the object being lifted and the ground must meet the minimum height of the traditional jack. It can be used to lift objects in narrow spaces.

[0031] (3) This invention solves the problem of poor intelligence of traditional jacks by real-time monitoring of the gas pressure in the airbag and the tilt angle of the object being lifted. It can check whether the object being lifted is in a balanced state and prevent instability and overturning. At the same time, when it is necessary to maintain a certain tilt angle of the lifting device in complex terrain, it can also monitor the tilt angle of the object in real time to ensure the accuracy of the lifting work.
