Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit installation technology, and more specifically, to a hoisting device for installing an air conditioner outdoor unit. Background Technology

[0002] The hoisting device can accurately lift the outdoor unit of the air conditioner from the ground or other locations to the designated installation position, solving the problem of handling during the installation process. By adjusting the height and angle of the hoisting device, it can be ensured that the outdoor unit of the air conditioner is placed in the correct position, facilitating subsequent fixing and connection work.

[0003] Among the existing publicly available documents, patent publication number CN221397058U discloses a hoisting and lifting device for HVAC installation. This technology places the device's crossbeam on top of the wall at the top floor, then starts the motor, causing the bidirectional threaded rod to rotate in place inside the horizontal groove. This allows the bushing and the clamping plate below it to be retracted, facilitating the anti-slip pad to be fixed to the outer wall from the side. The clamping distance between the main body and the clamping plate can be adjusted, facilitating the installation and lifting of the main body of the device at high-rise locations and solving the problem of poor stability. However, this technology still has the following problems.

[0004] When installing an outdoor unit of an air conditioner, a hoisting device is required. During the hoisting process, the hoisting ropes will rub against the hoisting arm, resulting in poor rope durability. This can easily lead to the ropes breaking during the hoisting process. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a hoisting device for installing an air conditioner outdoor unit, comprising a hoisting arm, a rope, and an electric cylinder. The rope is located on one side of the hoisting arm, and the electric cylinder is located between the hoisting arm and the rope. The electric cylinder is fixedly connected to the hoisting arm, and the output end of the electric cylinder is provided with a linkage lubrication assembly. The linkage lubrication assembly includes a socket block, a cleaning sleeve, a linkage bar, a sliding sleeve, a lubricating oil tank, and a lower exhaust valve pipe. The socket block is fixedly located on the sensing end of the electric cylinder, the cleaning sleeve is fixedly connected to one side of the socket block, and the linkage bar is fixedly located on the other side of the socket block. The socket block is slidably connected to the hoisting arm. The sliding sleeve is fixedly located at the top of the linkage bar, the lubricating oil tank is fixedly located on the outer wall of the socket block and adjacent to the electric cylinder, and the lower exhaust valve pipe is inserted and connected to the bottom end of the lubricating oil tank. The lower exhaust valve pipe is used to lubricate the cleaning sleeve.

[0006] Preferably, both the connecting block and the cleaning sleeve are slidably connected to the rope. The cleaning sleeve is made of sponge material. Both the hoisting arm and the rope are slidably connected to the sliding sleeve. The inner walls of the sliding sleeve and the inner walls of the connecting block are smooth surfaces. A support is fixedly connected to the bottom end of the hoisting arm, and a mounting base is welded to the bottom end of the support. One end of the rope is wound around a take-up roller, and a take-up motor is installed at one end of the take-up roller. The take-up motor is used to drive the take-up roller to rotate, and the take-up motor is fixedly connected to the hoisting arm.

[0007] When this technology is used, the rope slides along the inner wall of the sliding sleeve and the connecting block. The electric cylinder is activated to drive the connecting block to tilt and move. The cleaning sleeve tilts and moves along the outer wall of the rope. The sliding sleeve tilts and moves along the outer wall of the rope. At the same time, the lower drain valve pipe is opened, and the lubricating oil in the lubricating oil tank is poured into the lower drain valve pipe. The cleaning sleeve can lubricate the outer wall of the rope.

[0008] Preferably, a linkage roller is rotatably connected to the inner wall of the other end of the hoisting arm, and a lifting sleeve is rotatably connected to the outer wall of the linkage roller, with a lifting hook fixedly installed at the bottom end of the lifting sleeve;

[0009] A support block is fixedly installed on one side of the lifting sleeve, and a connecting block is fixedly connected to the top of the support block. A positioning hole plate is welded to the top of the connecting block. The rope is slidably connected to the positioning hole plate. Multiple positioning rings are fixedly connected to the inner wall of the positioning hole plate, and the multiple positioning rings are arranged in a rectangular distribution. The vertical cross-section of the connecting block is concave, and the support block is used to support the connecting block. The inner walls of the multiple positioning rings are all smooth surfaces, and the cross-sectional shape of the positioning rings is circular.

[0010] When this technology is used, the rope drives the linkage roller to move upward, the suspension sleeve causes the hook to move upward, and the support block is supported by the suspension sleeve. Multiple positioning rings inside the positioning plate can slide and limit the outer wall of the rope.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model adopts a linkage lubrication component. The winding motor drives the winding roller to rotate, and the rope slides along the inner wall of the sliding sleeve and the connecting block. The connecting block drives the cleaning sleeve to move tilted, and the sliding sleeve moves tilted along the outer wall of the rope. Lubricating oil drips onto the cleaning sleeve through the lower valve pipe. The cleaning sleeve can lubricate the outer wall of the rope, thus preventing the rope from breaking during hoisting.

[0013] 2. In this utility model, when the rope moves upward and retracts, the rope will drive the linkage roller to move upward, and the hook will lift the air conditioner outdoor unit to the designated installation position. The connecting block provides support for the positioning hole plate, and the rope can slide and lift stably on the inner wall of multiple positioning rings. Attached Figure Description

The linkage lubrication component enables the cleaning sleeve 5 to lubricate the outer wall of the rope 2, thus preventing the rope from breaking during hoisting. The specific structure of the linkage lubrication component is as follows.

[0022] In this technical solution, such as Figure 1 - Figure 2As shown, rope 2 is located on one side of the hoisting arm 1, and electric cylinder 3 is located between the hoisting arm 1 and rope 2.

Both the hoisting boom 1 and the rope 2 are slidably connected to the sliding sleeve 7. The inner wall of the sliding sleeve 7 and the inner wall of the connecting block 4 are both smooth surfaces.

[0023] In this technical solution, such as Figure 3 As shown, a support 12 is fixedly connected to the bottom end of the hoisting arm 1, and a mounting base 13 is welded to the bottom end of the support 12; a winding roller 10 is wound around one end of the rope 2, and a winding motor 11 is installed at one end of the winding roller 10. The winding motor 11 is used to drive the winding roller 10 to rotate, and the winding motor 11 is fixedly connected to the hoisting arm 1 so that the mounting base 13 can be fixed at the installation position by expansion bolts. The support 12 is supported by the mounting base 13. By starting the winding motor 11, the winding motor 11 drives the winding roller 10 to rotate, and the winding roller 10 drives the rope 2 to be wound up.

[0024] When using the hoisting device for installing the outdoor unit of the air conditioner, the mounting base 13 is fixed to the installation position by expansion bolts. The mounting base 13 supports the support 12, and the support 12 supports the hoisting arm 1. After the outdoor unit of the air conditioner is tied up, it is installed on the hook 16. By starting the winding motor 11, the winding motor 11 drives the winding roller 10 to rotate. The winding roller 10 drives the rope 2 to wind up. The rope 2 slides along the inner wall of the sliding sleeve 7 and the connecting block 4. At the same time, the electric cylinder 3 is started to drive the connecting block 4 to tilt and move. The connecting block 4 drives the cleaning sleeve 5 to tilt and move. The cleaning sleeve 5 tilts and moves along the outer wall of the rope 2. At the same time, the linkage bar 6 drives the sliding sleeve 7 to tilt and move. The sliding sleeve 7 tilts and moves along the outer wall of the rope 2. At the same time, the lower drain valve pipe 9 is opened, and the lubricating oil in the lubricating oil tank 8 is poured into the lower drain valve pipe 9. The lubricating oil drips onto the cleaning sleeve 5 through the lower drain valve pipe 9, so that the cleaning sleeve 5 can lubricate the outer wall of the rope 2.

The inner walls of the multiple positioning rings 20 are all smooth surfaces, and the cross-sectional shape of the positioning rings 20 is circular.

[0026] When the hoisting device for installing the outdoor unit of the air conditioner is in use, as the rope 2 moves upward and retracts, the rope 2 will drive the linkage roller 14 to move upward. The linkage roller 14 will drive the lifting sleeve 15 to move upward, and the lifting sleeve 15 will cause the hook 16 to move upward. The hook 16 will lift the outdoor unit of the air conditioner to the designated installation position. The support block 17 is supported by the lifting sleeve 15, and the support block 17 supports the connecting block 18. The connecting block 18 provides support force to the positioning hole plate 19. The multiple positioning rings 20 inside the positioning hole plate 19 can slide and limit the outer wall of the rope 2, so that the rope 2 can be stably lifted by sliding on the inner wall of the multiple positioning rings 20.
