detailed description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in the figure, the lifting device for the adjustable air conditioner outdoor unit in the present invention includes a fixed base 1, a height adjustment device 3 arranged on the fixed base 1 through a bracket 2, a movable support 4 arranged on the height adjustment device 3 and The cantilever 5 and the motor 6 are arranged on the movable support 4; the height adjusting device 3 is mainly composed of a box body 31, a rotating shaft 32, a screw shaft 33 and a pair of mutually meshing gears 34, and a pair of gears 34 are located in the box Inside the body 31 and correspondingly arranged at one end of the rotating shaft 32 and the screw shaft 33, the rotating shaft 32 and the screw shaft 33 are respectively arranged on the box body 31 through bearings; the movable support 4 is set on the screw shaft 33 Under the drive of the gear 34, it moves up and down along the axis of the screw shaft 33. The suspension end of the cantilever 5 is provided with a pulley 7, and one end of the steel rope 8 is provided with a hook 11, and the other end goes around the pulley 7 and is wound. on motor 6.

Specifically, the bracket 2 and the fixed base 1 are fixed together, the gear 34 in the height adjustment device 3 is a bevel gear, and the rotating shaft 32 and the screw shaft 33 are vertically arranged on the box body 31, wherein the rotating shaft 32 is provided with The handle is used as an input shaft, and the screw shaft 33 is correspondingly used as an output shaft. The movable support 4 is provided with a threaded hole, and the screw shaft 33 cooperates with the threaded hole, and the lifting power is provided to the movable support 4 by manually turning the handle to realize the cantilever. 5 and the lifting or rotation of motor 6. The structure is simple, easy to operate, the height and angle of the device can be adjusted according to the situation, the use is flexible, and it is easy to carry. An anti-rotation pin 42 is provided between the movable support 4 and the box body 31. When the anti-rotation pin 42 is inserted, the limit to the movable support 4 can be realized. When the anti-rotation pin 42 is pulled out, the rotating wire The lever shaft 33 can drive the movable support 4 to rotate to realize the adjustment of the angle of the cantilever 5 .

The cantilever 5 in this embodiment is composed of a cantilever body 51 and a pull rod 52. The cantilever body 51 is a folding structure, and one end is fixed on the movable support 4. The pulley 7 is arranged on the other end of the cantilever body 51. Both ends of the pull rod 52 are detachably connected to the cantilever body 51 and the lug 41 provided on the movable support 4 respectively.

Specifically, a cylindrical pin for connecting the pull rod 52 is installed on the foldable cantilever body 51. One end of the pull rod 52 is hung on the cylindrical pin, and the other end is connected to the lug 41 of the movable support 4 through a detachable fastener. Installing the tie rod 52 can realize the tension suspension of the cantilever body 51, and removing the tie rod 52 can realize the folding of the cantilever body 51, thereby reducing the space occupation area of the device and facilitating transportation.

The fixed base 1 in this embodiment is inserted with a counterweight pedestal 9 , and the counterweight pedestal 9 is connected to the fixed base 1 in a telescopic and adjustable manner. Specifically, the counterweight pedestal 9 is inserted into the socket on the fixed base 1 through two plugs, so that the telescopic adjustment of the counterweight pedestal 9 can be pulled out or pushed in, and then connected with the fixed base 1 through pins to realize positioning. , the structure can change the size of the base, so that it can adapt to different situations such as handling and hoisting.

The bottom of the fixed base 1 in this embodiment is provided with casters 10, which is convenient for moving the whole device.

The lifting device has two states: one is the transport state; the other is the working state.

The transportation state refers to the process of moving the lifting device to the roof of the building through the elevator or the corridor. In this state, the pull rod 52 is removed, and the cantilever body 51 is folded to allow it to hang freely, so as to reduce the overall height of the lifting device. In addition, the counterweight pedestal 9 is pushed into the fixed base 1 to reduce the overall length of the lifting device. At this time, the anti-rotation bolt 42 should be inserted on the casing 31 to prevent the movable support 4 from rotating, as shown in FIG. 3 .

The working state refers to the lifting state of the lifting device. As shown in FIG. 1 , after the lifting device is transported in place, the cantilever body 51 is propped up first, and the pull rod 52 is fixed on the cantilever body 51 and the lug 41 of the movable support 4 . Rotate the handle to drive the screw shaft 33 to rotate through the gear 34. Due to the anti-rotation effect of the anti-rotation bolt 42, the movable support 4 can only move up and down, so as to adjust the overall height of the cantilever 5. In addition, the counterweight pedestal 9 is pulled out from the fixed base 1 to adjust the overall length of the base, and a counterweight is added to the counterweight pedestal 9 according to the length of the base. Then, the hoisting device is pushed to a reasonable hoisting position, and the caster 10 is fixed. Start the motor 6 and lower the hook 11 to the installation position of the outdoor unit of the air conditioner. After the hook 11 hooks the air conditioner that has been tightened, the motor 6 rotates and lifts the outdoor unit of the air conditioner. When it is lifted to the roof, remove the anti-rotation pin 42 , turn the handle, drive the screw shaft 33 to rotate, drive the movable support 4 to rotate, the cantilever 5 and the air conditioner outdoor unit are rotated to a position that is convenient for placement, and then the motor 6 is rotated to make the air conditioner outdoor unit fall on a place that is convenient for operation.

Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that it can be described in terms of form and Various changes may be made in the details without departing from the scope of the invention defined by the claims.
