The sliding member has a first gear rotatably mounted on it, which meshes with the first rack. A second gear is also movably mounted on the sliding member. The sliding member also has a second rack in the vertical direction, which meshes with the first rack. The second rack is engaged. The lifting device also includes a hand chain hoist and a hook assembly. The hand chain hoist is mounted on the sliding member. The drive end of the hand chain hoist is connected to the second gear. The lifting chain of the hand chain hoist is movably connected to the hook assembly. The hook assembly is used to lift heavy objects. The lifting device also includes a first guide rope and a second guide rope. The first guide rope is connected to the sliding member and can pull the sliding member to move on the main guide rail. The second guide rope is connected to the second gear and can pull the second gear to move on the second rack.

[0008] In some embodiments, the hook assembly includes a hook body, a hook pulley, and a housing. The hook pulley is rotatably mounted on the housing. The lifting chain of the hand chain hoist is wound around the hook pulley. The hook body is mounted on the housing and used for lifting heavy objects.

[0009] In some embodiments, pin holes are provided on adjacent sub-guide rails, and the pin holes on adjacent sub-guide rails are correspondingly provided and connected by fasteners.

[0010] In some embodiments, the slider is triangular, and the slider has the groove along one side of itself.

[0011] In some embodiments, the slider has a guide groove, the guide groove is parallel to the second rack, a guide rod is slidably disposed in the guide groove, and the guide rod is rotatable, and the guide rod is coaxially connected to the second gear.

[0012] In some embodiments, both the guide groove and the second rack are zigzag-shaped.

[0013] In some embodiments, the lifting device further includes a camera assembly, which includes a camera and a gimbal stabilizer, the gimbal stabilizer being mounted on the slider and the camera being mounted on the gimbal stabilizer.

[0014] In some embodiments, the camera assembly further includes a display located outside the interior cavity of the industrial compressor and communicatively connected to the camera.

[0015] In some embodiments, the lifting device further includes a first support frame, which is V-shaped and used to support the main guide rail.

[0016] In some embodiments, the lifting device further includes a second support frame for supporting the main guide rail. The second support frame has a through hole through which the main guide rail can be movably inserted.

[0017] The beneficial effects of this utility model are:

[0018] This utility model discloses a lifting device for the inner cavity of an industrial compressor, comprising a main guide rail and a sliding member. The main guide rail can be mounted in the inner cavity of the industrial compressor and includes multiple sequentially connected sub-guide rails arranged at an angle between adjacent sub-guide rails. The sliding member has a groove in which the main guide rail can be engaged. A first rack is provided along the length of the main guide rail. A first gear is rotatably provided on the sliding member, and the first gear meshes with the first rack. A second gear is also movably provided on the sliding member. A second gear is also provided on the sliding member in the vertical direction. The lifting device includes a rack and pinion, a second gear meshing with the second rack and pinion, a hand chain hoist and a hook assembly, the hand chain hoist being mounted on a sliding member, the drive end of the hand chain hoist being connected to the second gear, the lifting chain of the hand chain hoist being movably connected to the hook assembly, the hook assembly being used for lifting heavy objects, and the lifting device also includes a first guide rope and a second guide rope, the first guide rope being connected to the sliding member and being able to pull the sliding member to move on the main guide rail, the second guide rope being connected to the second gear and being able to pull the second gear to move on the second rack and pinion. When heavy objects need to be transported from inside an industrial compressor, the main guide rail can be installed inside the compressor. Since the hook assembly is mounted on a hand-operated hoist, which in turn is mounted on a sliding component, the sliding component can slide along the length of the main guide rail. When the first traction rope is pulled, the hook assembly can lift the heavy object and move it along the length of the main guide rail in the traction direction, eliminating the need for manual handling and improving transportation efficiency. Furthermore, the main guide rail includes multiple sequentially connected sub-guide rails, with adjacent sub-guide rails set at an angle. Therefore, before transportation, the angle between adjacent sub-guide rails can be set according to the spatial layout of the industrial compressor cavity, ensuring the main guide rail adapts to the internal space. During transportation, neither the sliding component nor the main guide rail will collide with the equipment inside the industrial compressor cavity, preventing equipment damage and significantly improving safety. When the sliding component slides, the first gear, which is rotatably mounted on the sliding component, moves on the first rack, ensuring that the sliding component moves strictly along the length direction of the main guide rail, thus improving transportation stability. Furthermore, a second gear is also movably mounted on the sliding component, and a second rack is also mounted vertically on the sliding component. The second gear meshes with the second rack. A hand-operated hoist is installed on the sliding component, and its drive end is connected to the second gear. When the second traction rope is pulled, the second traction rope drives the second gear to move on the second rack, causing the second gear to rotate. This rotation of the second gear drives the drive end of the hand-operated hoist to rotate, thus raising the lifting assembly. Workers can adjust the height of the load by pulling the second guide rope as needed, based on the interference between the load and the equipment below, further preventing collisions between the load and the equipment and further improving the operational safety of the lifting device.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it.

They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0027] This embodiment proposes a lifting device for the inner cavity of an industrial compressor to solve the problems of low adaptability, poor safety, and low efficiency of existing lifting devices for the inner cavity of industrial compressors.

[0028] like Figure 1 As shown, a lifting device for the inner cavity of an industrial compressor includes a main guide rail 1 and a sliding member 2. The main guide rail 1 can be mounted in the inner cavity of the industrial compressor. The main guide rail 1 includes multiple sub-guide rails connected in sequence, with adjacent sub-guide rails arranged at an angle. The sliding member 2 has a sliding groove, in which the main guide rail 1 can be engaged. The main guide rail 1 has a first rack 3 arranged along its own length direction. The sliding member 2 is rotatably equipped with a first gear 4, which meshes with the first rack 3. A second gear is also movably arranged on the sliding member 2. The sliding member 2 also has a second rack arranged vertically. The second gear meshes with the second rack. The lifting device also includes a hand chain hoist 5 and a hook assembly 6. The hand chain hoist 5 is mounted on the sliding member 2. The drive end of the hand chain hoist 5 is connected to the second gear. The lifting chain 51 of the hand chain hoist 5 is movably connected to the hook assembly 6. The hook assembly 6 is used to lift heavy objects. The lifting device also includes a first guide rope 7 and a second guide rope. The first guide rope 7 is connected to the sliding member 2 and can pull the sliding member 2 to move on the main guide rail 1. The second guide rope is connected to the second gear and can pull the second gear to move on the second rack.

[0029] Understandably, when it is necessary to transport heavy objects inside the industrial compressor cavity, the main guide rail 1 can be installed inside the industrial compressor cavity. Since the hook assembly 6 is installed on the hand chain hoist 5, and the hand chain hoist 5 is installed on the sliding member 2, the sliding member 2 can slide along the length direction of the main guide rail 1. When the first traction rope is pulled, the hook assembly 6 can lift the heavy object and move it along the length direction of the main guide rail 1, eliminating the need for manual handling of heavy objects and improving transportation efficiency. Moreover, the main guide rail 1 includes multiple sub-guide rails connected in sequence, with adjacent sub-guide rails set at an angle. Therefore, before transportation, the angle between adjacent sub-guide rails can be set according to the spatial layout of the industrial compressor cavity, so that the main guide rail 1 adapts to the spatial layout of the industrial compressor cavity. During transportation, neither the sliding member 2 nor the main guide rail 1 will collide with the equipment inside the industrial compressor cavity, avoiding equipment damage and greatly improving safety. When the sliding member 2 slides, the first gear 4, which is rotatably mounted on the sliding member 2, moves on the first rack 3, so that the sliding member 2 moves strictly in the length direction of the main guide rail 1, improving the transportation stability. Since the sliding member 2 is also movably mounted with a second gear, and the sliding member 2 is also mounted with a second rack in the vertical direction, the second gear meshes with the second rack. The hand chain hoist 5 is installed on the sliding member 2, and the drive end of the hand chain hoist 5 is connected to the second gear. When the second traction rope is pulled, the second traction rope drives the second gear to move on the second rack, thereby generating the rotation of the second gear. The rotation of the second gear drives the drive end of the hand chain hoist 5 to rotate, thus enabling the lifting component to rise. The operator can pull the second guide rope as needed according to the interference between the heavy object and the equipment below, control the height of the heavy object, further avoid the heavy object from colliding with the equipment, and further improve the operational safety of the lifting device.

[0030] In some optional embodiments, the hook assembly 6 includes a hook body 61, a hook pulley, and a housing 62. The hook pulley is rotatably mounted on the housing 62, and the lifting chain 51 of the hand chain hoist 5 is wound around the hook pulley. The hook body 61 is mounted on the housing 62 and used for lifting heavy objects. Understandably, when the lifting chain 51 of the hand chain hoist 5 rotates and shortens, it enables the hook pulley to rotate, preventing wear on the lifting chain 51. The shortening of the lifting chain 51 drives the housing 62 to rise, thereby allowing the hook body 61 to rise with the heavy object. The operation is stable and the structure is reliable, improving the structural rationality of the lifting device.

[0031] In some optional embodiments, pin holes are provided on adjacent sub-guide rails, and the pin holes on adjacent sub-guide rails are correspondingly provided and connected by fasteners. This arrangement allows for adjustment of the included angle between adjacent sub-guide rails by removing and installing fasteners, facilitating adjustment of the shape of the main guide rail 1 to adapt to the spatial layout of the industrial compressor cavity, thereby improving the usability of the lifting device.

[0032] For example, the pin hole has an internal thread, and the fastener is a threaded rod that engages with the threaded pin hole. Understandably, when it is necessary to adjust the angle between the sub-guide rails, the fastener can be unscrewed first, and after the sub-guide rail angle is adjusted, the fastener can be tightened to fix the angle, thus improving the ease of operation of the lifting device.

[0033] In some optional embodiments, the slider 2 is triangular, and a groove is formed along one side of the slider 2. This design reduces the weight of the slider 2 while ensuring its sliding stability, thereby improving the reliability of the lifting device.

[0034] In some optional embodiments, the sliding member 2 has a guide groove parallel to the second rack, and a guide rod is slidably disposed in the guide groove. The guide rod is capable of rotation and is coaxially connected to the second gear. This arrangement allows the second gear to drive the guide rod to rotate when it moves on the second rack, and the guide rod slides in the guide groove, improving the stability of the second gear during movement and thus enhancing the reliability of the lifting device.

[0035] In some alternative embodiments, both the guide groove and the second rack are zigzag-shaped. This arrangement allows the guide groove and the second rack to be longer in a limited space, thereby increasing the number of rotations of the second gear, extending the lifting distance of the chain hoist 5, expanding the lifting height of heavy objects, and improving the usability of the lifting device.

[0036] In some optional embodiments, the lifting device further includes a camera assembly 8, which includes a camera 81 and a gimbal 82. The gimbal 82 is mounted on the sliding member 2, and the camera 81 is mounted on the gimbal 82. This setup allows the camera 81 to observe the movement trajectory of the load during transportation and determine whether the load interferes with the equipment inside the industrial compressor cavity. The height of the load can then be adjusted as needed. Furthermore, the gimbal 82 prevents camera 81 from shaking and affecting the accuracy of the observation, thereby improving the reliability of the lifting device.

[0037] In some optional embodiments, the lifting device also includes a display 83, located outside the industrial compressor cavity and communicatively connected to a camera 81. This arrangement facilitates external observation of the heavy load transportation process, improving transportation convenience.

[0038] It is worth noting that the chain hoist 5, camera 81, anti-shake gimbal 82 and display 83 can be mature products on the market, and this embodiment does not impose too many restrictions.

[0039] In some alternative embodiments, the lifting device further includes a first support frame 9, which is V-shaped and used to support the main guide rail 1. This arrangement improves the support stability of the first support frame 9 on the main guide rail 1, thereby enhancing the safety of the lifting device.

[0040] In some optional embodiments, the lifting device further includes a second support frame 10 for supporting the main guide rail 1. The second support frame 10 has a through hole through which the main guide rail 1 can be movably inserted. This arrangement further improves the support stability of the main guide rail 1, prevents the main guide rail 1 from tipping over, and thus improves the safety of the lifting device.

[0041] For example, the first support frame 9 is disposed upstream of the main guide rail 1 and the sliding member 2, and the second support frame 10 is disposed downstream of the main guide rail 1 and the sliding member 2. This arrangement allows the first and second support members to support the main guide rail 1 from both ends, further improving the support stability and avoiding interference between the first and second support members and the sliding member 2, thus improving the structural rationality of the lifting device.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
