In the utility model, in the using process, when the working personnel is on the ground, the machine base 1 can be fixed on the lifting working platform, the device can lift along with the working platform and the working personnel, after arriving at the working place, when the working personnel need to convey tools and disassembled equipment to the ground at high altitude, the mooring rope 21 can be wound around the sliding roller 12 and then connected with the object to be transported, the object can drive the winding roller 2 to rotate at high speed and arrange the line under the influence of gravity in the falling process, at the moment, the working personnel can press the sliding rod 15 on the side plate 11 to force the rubber block 16 at the tail end of the sliding rod 15 to rub against one side of the winding roller 2, thereby achieving the effect of limiting the rotating speed of the winding roller 2 and putting down the object, avoiding the limitation caused by the lack of the winding roller 2, the inertia drives the winding roller 2 to continue to rotate after the object falls, the winding problem of the winding roller 2 is caused;

when the objects on the ground are required to be conveyed to the working platform, the objects can be connected with the hook 22, then, depending on the weight of the article to be lifted, it is selected whether the insert 33 fixing the socket 34 to the large gear 32, or the insert 33 fixing to the small gear 31, because the axes of the pinion 31 and the winding roll 2 are the same, the worker can pull out the rocker arm 35 in the socket 34 by rotating the base 1 by the pinion 31 and rotating the winding roll 2 for one circle, so that the distance between the rocker arm 35 and the socket 34 is longer, when the rocker arm 35 is inserted into the fixing hole 37 and is screwed with the plug bolt 36, the rocker arm 35 is fixed, and since the handle on the rocker arm 35 is far from the socket 34, therefore, when the worker rotates the socket 34, the shaking is formed greatly, so that labor is saved, and the worker can lift heavy objects conveniently;

if only an object with small volume and light weight needs to be lifted, the inserting block 33 for fixing the socket 34 on the large gear 32 can be selected, then the rocker arm 35 penetrates through the socket 34, so that the distance between the crank on the rocker arm 35 and the socket 34 is closer, at the moment, when a worker holds the crank, the socket 34 is rotated faster, meanwhile, the socket 34 rotates to drive the large gear 32 to rotate synchronously, and because the diameter of the large gear 32 is larger than that of the small gear 31, when the number of times of rotating the socket 34 is fixed, the number of turns of the small gear 31 is more than that of the large gear 32, so that the winding roller 2 is driven to rotate more turns, and the lighter tool which is more rapid and convenient for the worker to lift;

when the article is lifted to a certain height and needs to be fixed, the locking inserted rod 25 can penetrate through the fixing lug 24 and be inserted into the through hole in the side plate 11, so that the winding roll 2 can be fixed, and the winding roll 2 is prevented from rotating.

As shown in fig. 3, the ratio of the diameters of the large gear 32 and the small gear 31 is four to one.

It should be noted that, as an example, the large gear 32 rotates one turn and simultaneously drives the small gear 31 to rotate four turns, thereby driving the winding roller 2 to rotate four turns.

As shown in fig. 5, the number of the fixing holes 37 opened in the rocker arm 35 is four, and the four fixing holes 37 are opened outside the rocker arm 35 in the longitudinal direction of the rocker arm 35.

It should be noted that, as an example, when the plunger bolt 36 penetrates through the bottom fixing hole 37 of the swing arm 35, the distance between the crank on the additional swing arm 35 and the socket 34 is longer, and the large-stroke rotation is more labor-saving.

As shown in fig. 4, a spring 14 is installed outside the opening of the sliding chute 13 on the side plate 11, and one end of the spring 14 is connected with the side plate 11, and the other end of the spring 14 is connected with the sliding rod 15.

Preferably, the sliding rod 15 is located in the sliding groove 13, and a rubber block 16 is fixedly connected to one end of the sliding rod close to the winding roller 2.

It should be noted that, in the normal state of the slide rod 15, the rubber block 16 at the end does not rub the winding roller 2, and only when the operator presses the slide rod 15, the rubber block 16 limits the rotation speed of the winding roller 2.

Preferably, four clamping beads are mounted on the outer side of the plug block 33, four clamping bead grooves are formed in the socket 34, and the plug block 33 is connected with the socket 34 in a clamping mode.

It should be noted that the worker can insert the socket 34 into any one of the insertion blocks 33 on the small gear 31 and the large gear 32 at any time.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention.
