[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1-Figure 5As shown, the intelligent telescopic hoisting machine of the present invention comprises an outer sleeve 1, an inner sleeve 2 is slidably connected inside the outer sleeve 1, a driving mechanism 3 is provided on one side of the outer sleeve 1, the driving mechanism 3 is used to drive the inner sleeve 2 to slide horizontally, a wire drum 4 is rotatably installed on the top support plate of the outer sleeve 1, a rotating shaft on one side of the wire drum 4 is docked with a motor A5, a lifting rope 7 is wound on the wire drum 4, one end of the lifting rope 7 is connected with a hanging hook 8, and the lifting rope 7 fits the top of a pulley 6, and the pulley 6 is rotatably connected to the inner side of the bracket at the top of the inner sleeve 2, the driving mechanism 3 comprises a horizontal plate 31 fixed to the side wall of the outer sleeve 1, a motor B32 is installed at the bottom of the horizontal plate 31, a gear 33 is installed on the top of the motor B32, one end of the gear 33 passes through the opening of the side wall of the outer sleeve 1 and meshes with a tooth path 34 arranged on one side of the inner sleeve 2.

[0029] As mentioned above, when the present invention is in use, the outer sleeve 1 can be assembled on the top of the kitchen or other rooms with windows, and the inner sleeve 2 can be extended out of the window. Then, when lifting items, the motor B32 is started to rotate the gear 33, and the inner sleeve 2 is moved outward and out of the window through the meshing tooth path 34. The motor A5 is started synchronously to unwind the bobbin 4, and the lifting rope 7 moves stably through the pulley 6, and drives the hanging hook 8 to descend to the specified position. Finally, the user hangs the item on the hanging hook 8, starts the motor A5 to rewind the item to a suitable height, and the motor B32 and the motor A5 are started synchronously again to move the inner sleeve 2 and the item back to the inside of the window, so that the item can be taken down after going upstairs. In this way, it will not be so laborious to transport the items to high-rise buildings, and the practicality is very good. The weighing capacity can be selected and assembled in the range of 50 to 1000 kilograms, so that in the event of a fire indoors, it can also be used as a high-rise escape tool. For example, the hanging hook 8 can be hung on a relatively high-altitude escape jacket, which is more applicable.

[0030] A pulley 2 9 is installed horizontally and rotatably on the inner side of a bracket near the position of the wire drum 4 at the top of the outer sleeve 1, and a lifting rope 7 passes through and fits through the bottom of the pulley 2 9; a pulley 4 11 is installed horizontally and rotatably on the inner side of a bracket at one end of the inner sleeve 2, and the lifting rope 7 passes through and fits through the top surface of the pulley 4 11.

[0031] As mentioned above, in the optimization of the stability of the operation of the lifting rope 7, the top surface of the lifting rope 7 is limited by the pulley 2 9, so that the lifting rope 7 has better stability when being pulled or unwound. Secondly, the pulley 4 11 can prevent the horizontal to vertical part of the lifting rope 7 from contacting the inner sleeve 2, thereby avoiding the wear of the lifting rope 7 and also improving the stability effect.

[0032] Two alloy plates 13 are nailed to both sides of one end of the outer sleeve 1, the bottom of the alloy plate 13 is nailed to the top of the beam 16, and the two ends of the beam 16 are nailed to the top of the L-shaped steel frame 15. Two limit shafts 14 are rotatably connected between the two alloy plates 13, and the two limit shafts 14 are in contact with the upper and lower surfaces of the inner sleeve 2 respectively. An assembly frame 18 is sleeved on the outside of the end of the outer sleeve 1 away from the alloy plate 13, and a mounting tube 17 is fixed on the top of the assembly frame 18. The steel plate on the top of the mounting tube 17 is installed and fixed by bolts.

[0033] As mentioned above, in terms of overall assembly and operational stability optimization, the assembly frame 18 is pre-mounted on the outer sleeve 1 and nailed. During assembly, the L-shaped steel frame 15 is installed on the two inner sides of the upper end of the window, and then the cross beam 16 is fixed to the top of the L-shaped steel frame 15. Then the alloy plate 13 is first fixed to the cross beam 16, and finally the steel plate on the top of the mounting tube 17 is fixed to the roof by bolts. This assembly is very stable and firm, not easy to loosen, and has a reasonable design to meet the installation of the window position. At the same time, the two limiting shafts 14 further limit the inner sleeve 2, making it more stable in the up and down directions, thereby improving the stability of item transportation.

[0034] The support plates for connecting the motor A5 and the bobbin 4 shaft are fixed to the bottom of the horizontal steel plate 19, and the horizontal steel plate 19 is nailed to the top of the outer sleeve 1. Two vertical and inclined reinforcing steel plates 20 are fixed to the bottom of the horizontal steel plate 19, and the two reinforcing steel plates 20 are connected together, and the vertical reinforcing steel plate 20 is in contact with the side wall of the outer sleeve 1.

[0035] As described above, the horizontal steel plate 19 and the two vertical and inclined reinforcing steel plates 20 form a triangular support structure, so that the portion of the motor A5 that extends beyond the outer sleeve 1 can also be effectively reinforced and supported, thereby improving stability.

[0036] A bearing seat 35 is fixed on one side of the outer sleeve 1 , a bearing body 36 is installed inside the bearing seat 35 , and the bearing body 36 is butted against the axle of the gear 33 .

[0037] As mentioned above, since the inner sleeve 2 has a certain weight, the gear 33 is relatively large when operating, which can easily cause damage to the shaft of the motor B32. Therefore, the bearing body 36 inside the bearing seat 35 is connected to the gear 33 to limit the top of the gear 33, making its rotation more stable and less prone to damage.

[0038] The lifting rope 7 passes through the wireless controller 12, and the wireless controller 12 slides outside the lifting rope 7. The elastic switch on the top of the wireless controller 12 automatically turns off the motor A5 after touching the bracket of the pulley four 11. The elastic switch on the top of the wireless controller 12 is designed as a ring plate and is passed through by the lifting rope 7 to form a sliding connection. The bottom of the ring plate is elastically connected to the top of the wireless controller 12 through a spring.

[0039] As mentioned above, since it is inconvenient to observe and determine when the items are transported to the appropriate height downstairs, a wireless controller 12 is additionally designed. When the bracket corner of the elastic switch pulley four 11 on the top of the wireless controller 12 is turned and it is started, the motor A5 can be automatically turned off, further improving the intelligence. It should be noted that the lifting device automatically shuts down using the wireless controller 12, which is a commonly used design, so its specific structure will not be repeated in this article.

[0040] Two contact sensing switches 10 are installed at the bottom of the outer sleeve 1, and the contact sensing switches 10 are electrically connected to the motor A5 and the motor B32.

[0041] As described above, the initial position of the inner sleeve 2 or the hanging hook 8 can be adjusted by hand through the contact induction switch 10, which is very convenient.

[0042] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
