[0002] In the production, assembly, testing, repair and transportation of small shells, it is often necessary to lift, position and flip the workpiece. Traditional large equipment such as hydraulic or electric bridge cranes and overhead cranes are difficult to adapt to small workshops, assembly lines or laboratory scenarios with limited space due to their large size, high cost and complicated operation.

[0003] While existing small lifting and handling equipment (such as manual hoists and simple balancers) are more suitable for the needs in terms of size, they are inconvenient to move in actual use, require special space tracks or fixed installation positions, and cannot meet the needs of rapid conversion between multiple workstations. In addition, they have poor versatility for shells of different shapes, sizes and weights, and the operation of changing clamps or adjusting height is cumbersome.

[0004] Therefore, there is an urgent need to develop a new type of hoisting equipment that is compact in structure, lightweight, freely movable, easy to operate, and accurately positioned. It should be able to stably adsorb or clamp small shells and be compatible with a variety of working scenarios. Utility Model Content

[0020] This utility model proposes a movable pneumatic hoisting device for small shells. By setting up a cylinder piston rod Y-shaped connecting block 02 and a pin 04, when it is necessary to hoist, position and flip small shell workpieces, compared with the prior art, the cylinder power unit 06 can push the same length to move the workpiece a greater distance, thereby saving operating space and improving the applicability and operational flexibility of the device.

[0021] Example: In this embodiment, the structure of a movable pneumatic hoisting device for a small housing is as follows: Figures 1 to 5As shown, the hoisting device of this utility model includes a hoisting beam 03 and a movable chassis 05. The bottom end of the hoisting beam 03 is fixedly equipped with a first cylindrical hole 03-10, a second cylindrical hole 03-20, and a third cylindrical hole 03-30. The first cylindrical hole 03-10 is fixedly installed at the bottom end of the hoisting beam 03 near the pin 04, and the third cylindrical hole 03-30 is fixedly installed at the bottom end of the hoisting beam 03 away from the pin 04. A flexible hook 01 is installed at one end of the hoisting beam 03. A cylinder power unit 06 is fixedly installed at the top of the movable chassis 05. A cylinder piston rod Y-shaped connecting block 02 is fixedly installed at the top of the cylinder power unit 06. The bottom end of the hoisting beam 03 is rotatably mounted... A slider 11 is fixedly installed on the top of the movable chassis 05 between the top ends of the Y-shaped connecting blocks 02 of the cylinder piston rod. The slider 11 is C-shaped, and elongated grooves are opened on both sides of the slider 11. The slider 11 is connected to one end of the lifting beam 03 by a pin 04. It is worth noting that the first cylindrical hole 03-10 and the pin 04 are interference-fitted, which can form a firm and non-moving connection between the first cylindrical hole 03-10 and the pin 04, enhancing the overall rigidity and stability of the structure. The second cylindrical hole 03-20 is clearance-fitted to the top end of the Y-shaped connecting block 02 of the cylinder piston rod, and the third cylindrical hole 03-30 is clearance-fitted to the top end of the flexible hook 01. This design allows for relative movement between the second cylindrical hole 03-20 and the cylinder piston rod Y-shaped connecting block 02, or between the third cylindrical hole 03-30 and the flexible hook 01, while avoiding problems such as motion jamming and accelerated wear caused by interference or over-fitting. It also simplifies the assembly process and facilitates installation and debugging. Furthermore, the second cylindrical hole 03-20 is fixedly installed at the bottom end of the lifting beam 03 near the pin 04 at the midpoint. This design allows the operator to activate the cylinder power unit 06 when the workpiece needs to be lifted, causing the cylinder power unit 06 to move the cylinder piston rod Y-shaped connecting block 02. The cylinder piston rod Y-shaped connecting block 02 then moves the lifting beam through the second cylindrical hole 03-20. 03. Movement: At this time, the cylinder piston rod Y-shaped connecting block 02 and the lifting beam 03 can be regarded as a lever structure. The lifting beam 03 rotates around the cylinder piston rod Y-shaped connecting block 02 as the axis, causing one end of the first cylindrical hole 03-10 to rotate downwards, and the other end of the third cylindrical hole 03-30 to drive the flexible hook 01 and the workpiece to rotate upwards. This saves operating space and allows the device to flexibly carry out lifting operations in small workshops, assembly lines or laboratories with limited space. It improves the adaptability of the device to different work positions and different layout environments, and enables the device to quickly switch between multiple work positions more conveniently without having to consider the space limitations on operation. This greatly improves the applicability and operational flexibility of the device.

[0022] Furthermore, the cylinder power unit 06 is selected based on the cylinder bore and the lifting distance from the ground, specifically as follows: ,in The cylinder bore should be selected according to... One size larger; In addition, for the calculation of the travel distance of pin 04 in slider 11, please refer to [link / reference needed]. Figure 4 and Figure 5 As shown: Step 1: Draw a circle with the cylinder installation distance as the radius and the center of the cylinder piston rod Y-shaped connecting block 02 (where the cylinder piston is not extended) as the center. Step 2: Using the cylinder installation distance as the radius, draw a circle with the center of the cylinder piston rod Y-shaped connecting block 02 when the cylinder piston is halfway extended; Step 3: Using the cylinder installation distance as the radius, draw a circle with the center of the cylinder piston rod Y-shaped connecting block 02 when the cylinder piston is fully extended; Step 4: Using the full extension of the piston rod as the length, intersect the three circles on the same vertical line; Step 5: At this point, you can measure the distance the pin 04 has moved by drawing a diagram; In summary, the elongated groove on one side of the slider 11 is customized based on the calculated movement distance of the pin 04 to avoid the limitation of the rotation range of the lifting beam 03 when the elongated groove is too short, thereby reducing the height of the flexible hook 01 and making it difficult for the lifting beam 03 to swing normally.

[0023] Furthermore, in this embodiment, as Figure 1 As shown, directional wheels 07 are symmetrically installed on the bottom of one side of the sliding chassis 05. The directional wheels 07 are all installed on the bottom of the sliding chassis 05 by the first locking bolt 08. On the other side of the sliding chassis 05, universal wheels 09 are symmetrically installed on the bottom of the sliding chassis 05. The universal wheels 09 are all installed on the bottom of the sliding chassis 05 by the second locking bolt 10. With this design, through the symmetrical configuration of the directional wheels 07 and universal wheels 09, the device can not only glide smoothly along a straight line, but also turn flexibly and rotate in place, meeting the needs of rapid job change in multi-workstation scenarios such as small workshops and assembly lines. It does not need to rely on tracks or fixed paths, and is suitable for shuttle operations in narrow spaces, improving the flexibility and stability of the device.

[0024] Furthermore, in this embodiment, as Figure 1As shown, the cylinder power unit 06 is fixedly installed on the top of the mobile chassis 05 by bolts 12. The flexible hook 01 can be quickly replaced according to different housing characteristics and operational requirements. This design, through the modular design of the base and clamping interface, allows the same equipment to be compatible with multiple end effectors. When facing a smooth surface of a small housing, a vacuum suction cup can be replaced; when facing a housing with flanges or corners, a mechanical claw can be replaced; and when facing a housing made of fragile materials, a flexible clamping component can be replaced. There is no need to configure separate equipment for different workpieces, reducing equipment investment costs. On the other hand, it also allows for the quick replacement of cylinder power units 06 of different sizes, facilitating the rapid replacement of end effectors with different functions to adapt to different housing shapes, improving the adaptability and working efficiency of the device. Moreover, it is simple to operate, labor-saving, and efficient, reducing the operator's labor intensity and improving production efficiency and safety.

[0025] Working principle: The device is pushed to the work site, and the flexible hook 01 is connected to the workpiece of small and medium-sized shell. The operator starts the cylinder power unit 06, so that the cylinder piston rod of the cylinder power unit 06 extends vertically under the action of the air source. At this time, the lifting beam 03 will move upward while swinging around the axis of the pin 04. At the same time, the pin 04 performs self-rolling and relative sliding motion in the long oval groove on one side of the slider 11, so that the other end of the lifting beam 03 drives the flexible hook 01 and the workpiece to the designated position, which facilitates the operator to assemble.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
