DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 A rapid recovery and deployment hoisting device in this embodiment includes a base 1, a fixing rod 2 is fixed to the top of the base 1, a connecting rod 3 is fixed to the bottom of the fixing rod 2, a hoisting box 4 is fixed to the lower surface of the connecting rod 3, an adjustment mechanism 5 for adjustment is provided on the hoisting box 4, and a hook 6 is provided on the adjustment mechanism 5.

[0023] It should be noted that, by operating the adjustment mechanism 5 and the hook 6, it is convenient for the operator to recycle and deploy the device conveniently, thereby realizing convenient adjustment of the hanging object, further improving the applicability of the device.

[0024] See also Figure 1-3 In order to conveniently adjust the suspended objects, the adjusting mechanism 5 in this embodiment includes a starting component, and the adjusting mechanism 5 also includes an adjusting component, on which a retracting and releasing component is provided; the starting component includes a dual-axis motor 501 fixed in the middle of the inner bottom wall of the lifting box 4, and the output shaft of the dual-axis motor 501 is fixed with two worms 502 which are rotatably connected to the left and right sides of the inner cavity of the lifting box 4 through bearings respectively, and a worm wheel 503 is meshed on the outer surface of the worm 502, and two support seats are fixed on the inner bottom wall of the lifting box 4, and the two support seats are respectively rotatably connected to the two worms 502, so that the rotation of the worm 502 can be more stable, thereby promoting the rotation of the worm wheel 503 to be more stable, and the outer surfaces of the two worms 502 are fixed with threaded strips with opposite spiral directions, and the starting of the dual-axis motor 501 drives the worm 502 and the worm wheel 503 to rotate, providing a power source for the operation of the adjusting component.

[0025] Among them, the adjustment component includes two groups of fixed seats fixed on the left and right sides of the inner bottom wall of the lifting box 4, and a first rotating rod 504 is rotatably connected between the two groups of fixed seats. The inner wall of the axis of the worm gear 503 is fixed to the middle of the outer surface of the first rotating rod 504, and the front and rear sides of the first rotating rod 504 are fixed with active bevel gears 505. The adjustment component also includes two second rotating rods 507 rotatably connected between the left and right sides of the inner cavity of the lifting box 4 through bearings, and the left and right sides of the outer surface of the second rotating rod 507 are fixed with driven bevel gears 506. The first rotating rod 504 is driven to rotate by the worm gear 503, thereby prompting the active bevel gear 505 to rotate, and then the second rotating rod 507 is driven to rotate by the meshing force, which can drive the retracting and releasing component to move, and then the hook 6 can be driven to move to adjust the height of the hook 6.

[0026] At the same time, the active bevel gear 505 is meshed with the driven bevel gear 506. The two driven bevel gears 506 are symmetrical about the center of the second rotating rod 507, and the two active bevel gears 505 are symmetrical about the center of the first rotating rod 504. This makes it more stable when the first rotating rod 504 drives the active bevel gear 505 to rotate, and further makes the first rotating rod 504 more stably drive the driven bevel gear 506 and the second rotating rod 507 to rotate stably.

[0027] In addition, the retracting and releasing assembly includes two retracting and releasing ropes 508 with one end fixed to the outer surface of the second rotating rod 507, and the lower ends of the two sets of retracting and releasing ropes 508 are fixed with connecting plates 509, and the lower surfaces of the connecting plates 509 are fixed to the upper surfaces of the hooks 6. Two connecting holes are provided on the front and rear sides of the lower surface of the lifting box 4, and the relative height of the connecting plates 509 and the ground is adjusted by the retracting and releasing ropes 508 so as to be suitable for hoisting objects of different heights.

[0028] It should be noted that the starting component provides a power source for the operation of the adjusting component, and the adjusting component can drive the retracting and deploying component to move, thereby adjusting the position of the hook 6 so as to facilitate the recovery and deployment of the device.

[0029] The working principle of the above embodiment is:

[0030] When it is necessary to adjust and retract the hook 6 according to actual conditions, the two worms 502 can be driven to rotate by starting the dual-axis motor 501, thereby promoting the rotation of the two worm wheels 503 meshing with the worm 502. Since the threads on the left and right sides of the outer surface of the worm 502 are opposite, the two first rotating rods 504 can be caused to rotate in opposite directions, thereby causing the two active bevel gears 505 located on the first rotating rod 504 to also rotate, and then the meshing force of the two active bevel gears 505 causes the two driven bevel gears 506 to rotate in the same direction, thereby driving the second rotating rod 507 to rotate stably. Since the left and right sides of the second rotating rod 507 are both subject to driving force, the second rotating rod 507 can rotate more stably, which can cause the lower ends of the two sets of retracting and releasing ropes 508 to move more stably at the same time, and can drive the connecting plate 509 and the hook 6 to adjust their positions, that is, according to the actual needs of hanging objects of different specifications, corresponding recovery and deployment adjustments can be conveniently performed, thereby improving the applicability of the device.
