Description

Technical Field

[0001] This utility model relates to pneumatic hoist accessories, specifically a lever-type lifting suspension device for pneumatic hoists. Background Technology

[0002] The current pneumatic hoist lifting suspension devices generally have the following problems: complex transmission switching, making it difficult to quickly realize the functional conversion between "hoist lifting" and "heavy object handling"; insufficient stability of the connection structure, with traditional supports mostly being single-sided or simple supports, and rotating parts being prone to shaking, affecting transmission accuracy; and limited functionality, with most devices only suitable for wire rope lifting or chain handling, unable to meet both operational needs, resulting in poor adaptability. Utility Model Content

[0003] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a toggle-type lifting suspension device for a pneumatic hoist, comprising a connecting frame disposed between the pneumatic hoist sprocket and the pneumatic hoist reducer, wherein a rotating shaft connected to the output shaft of the pneumatic hoist reducer is disposed at the center of the connecting frame, and a toggle shaft is telescopically connected to the end of the rotating shaft away from the pneumatic hoist reducer, wherein a spline groove is disposed at the end of the toggle shaft that can be connected to the splined part of the input shaft of the pneumatic hoist sprocket, and a toggle rod is placed on the upper part of the toggle shaft, the toggle rod being sleeved on a guide rod, and the guide rod being horizontally disposed on the connecting frame along the direction from the pneumatic hoist sprocket to the pneumatic hoist reducer.

[0004] Preferably, the connecting frame includes several support rods circumferentially arranged between the pneumatic hoist sprocket and the pneumatic hoist reducer. The support rods are provided with mounting plates that support the rotating shaft, and the rotating shaft is rotatably connected to the mounting plates through bearings.

[0005] Preferably, the portion of the rotating shaft located between the mounting plate and the pneumatic hoist reducer is wound with a steel wire rope.

[0006] Preferably, the end of the rotating shaft is provided with an annular groove that contacts the bottom of the actuating rod, and the guide rod is disposed between the pneumatic hoist sprocket and the mounting plate.

[0007] The advantages of this utility model compared with the prior art are as follows:

[0008] This utility model utilizes circumferentially distributed support rods and a dedicated mounting plate to form a stable support structure. Combined with a bearing-connected rotating shaft, it significantly reduces rotational sway and improves load-bearing and transmission stability. The actuating rod moves horizontally along the guide rod, directly driving the extension and retraction of the actuating shaft. The spline groove and sprocket spline section allow for quick docking / separation, enabling flexible switching between two transmission modes. The spline connection is tight, resulting in minimal power loss during transmission, and the design of the rotating shaft wrapped with wire rope further enhances transmission efficiency. Simultaneously, it is compatible with both "wire rope-driven hoist lifting" and "chain-driven heavy object handling," meeting the needs of different pneumatic hoist operating scenarios and offering wider applicability.

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0013] In the description of the embodiments of this utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0014] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0015] In the description of the embodiments of this utility model, "a plurality of" means at least two.

[0016] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] Example:

[0018] Combined with appendix Figure 1-3 This embodiment discloses a lever-type lifting suspension device for a pneumatic hoist, including a connecting frame 3 disposed between the pneumatic hoist sprocket 1 and the pneumatic hoist reducer 2. A rotating shaft 4, connected to the output shaft of the pneumatic hoist reducer 2, is centrally located on the connecting frame 3. A lever 5 is telescopically connected to one end of the rotating shaft 4 away from the pneumatic hoist reducer 2. A spline groove 6, which can connect to the splined portion of the input shaft of the pneumatic hoist sprocket 1, is provided at the end of the lever 5. A lever 7 is placed on the upper part of the lever 5, and the lever 7 is sleeved on a guide rod 8. The guide rod 8 extends along the pneumatic hoist sprocket 1 to the pneumatic hoist... The hoist reducer 2 is horizontally mounted on the connecting frame 3. The connecting frame 3 includes several support rods 301 circumferentially arranged between the pneumatic hoist sprocket 1 and the pneumatic hoist reducer 2. The support rods 301 are provided with mounting plates 302 that support the rotating shaft 4. The rotating shaft 4 is rotatably connected to the mounting plates 302 through bearings. A steel wire rope is wound on the part of the rotating shaft 4 located between the mounting plates 302 and the pneumatic hoist reducer 2. The end of the rotating shaft 4 is provided with an annular groove 501 that contacts the bottom of the actuating rod 7. The guide rod 8 is located between the pneumatic hoist sprocket 1 and the mounting plate 302.

[0019] In use, when the lever is not connected to the pneumatic hoist sprocket, the reducer drives the rotating shaft to rotate. The wire rope wound on the rotating shaft is wound or released as the rotating shaft rotates, thereby driving the pneumatic hoist to lift or lower. When the lever drives the lever shaft to move, so that the lever shaft is connected to the pneumatic hoist sprocket, the lever shaft drives the pneumatic hoist sprocket to rotate, thereby realizing the transmission of the pneumatic hoist chain wound on the pneumatic hoist sprocket and realizing the function of the pneumatic hoist to move heavy objects.
