Description

Technical Field

[0001] The utility model relates to the technical field of electric hoists, in particular to a uniform rope winding mechanism for a double-rope electric hoist. Background Art

[0002] Electric hoist is a special lifting equipment installed on overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places.

[0003] Announcement No. CN 213356789 U discloses a new type of double-drum anti-winding electric hoist, which adopts a double-drum form to replace the original single drum. When the lifting height is high, the drum length can be shortened to ensure the stability and safety of the working process. A new type of hook group is adopted, and its two movable pulleys are not coaxial and arranged on the same plane. The wire rope never crosses during the winding process of the drum, movable pulley, and fixed pulley, thereby realizing the anti-winding function of the wire rope and avoiding the inconvenience caused by the entanglement of the wire rope to the work. The two movable pulleys and the hook have their own independent shafts. The structure of the entire hook group is simple. When replacing the bearings and other wearing parts of any movable pulley or hook, it is only necessary to remove the shaft itself, and other movable pulleys or hooks are not affected, which is convenient for maintenance and replacement, saving time and effort, and simple to operate. However, the patent still has the following problems in actual use:

[0004] The new double-drum anti-winding electric hoist adopts a new type of hook group. Its two movable pulleys are not coaxial and are arranged on the same plane. The wire rope never crosses during the winding process of the drum, movable pulley and fixed pulley, thereby realizing the anti-winding function of the wire rope and avoiding the inconvenience caused by the entanglement of the wire ropes to the work. However, the wire rope cannot be evenly wound on the drum when winding, and the phenomenon of uneven overlapping winding is prone to occur. At the same time, when the drum rotates, since the wire rope is evenly wound on the drum, the hook will swing back and forth, which is not conducive to the stable lifting and lowering of the electric hoist.

[0005] A uniform rope winding mechanism for a double-rope electric hoist is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a double-rope electric hoist uniform winding mechanism to solve the problem that the new double-drum anti-winding electric hoist proposed in the above background technology adopts a new hook group, whose two movable pulleys are not coaxial and are arranged on the same plane. The wire rope does not cross at all during the winding process of the drum, movable pulley and fixed pulley, thereby realizing the anti-winding function of the wire rope and avoiding the inconvenience caused by the entanglement of the wire ropes to the work. However, the wire rope cannot be evenly wound on the drum when winding, and the phenomenon of uneven superposition winding is easy to occur. At the same time, when the drum rotates, since the wire rope is evenly wound on the drum, the hook will swing back and forth, which is not conducive to the stable lifting and lowering of the electric hoist.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a uniform rope winding mechanism for a double-rope electric hoist, comprising a uniform rope winding mechanism and a lifting motor installed on one side of the uniform rope winding mechanism;

[0008] A hook mechanism is provided at the bottom of the uniform rope winding mechanism, and a hook body is provided at the bottom of the hook mechanism;

[0017] Preferably, a plurality of spiral grooves are provided inside the rotating gear disk, the spiral grooves are internally slidably connected to a limiting slider, the bottom of the limiting slider is fixedly connected to an engaging sliding rod, the engaging sliding rod is slidably connected to the fixed disk through a telescopic groove, and the fixed disk is internally rotatably connected to a hook rotating rod.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the uniform rope winding mechanism of the double-rope electric hoist can utilize the reciprocating motor to drive the reciprocating threaded sleeve to drive the limiting ring to slide relatively on one side of the inside of the hanger by setting the uniform rope winding mechanism. Since the wire rope passes through the inside of the limiting ring, the uniform retraction and release of the wire rope can be achieved. By setting the hook mechanism, not only can the rotating toothed disc be rotated to fix or rotate the sliding rod and the fixing hole, but also the lifting angle of the hook body can be controlled. The specific contents are as follows:

[0020] 1. By setting up a uniform rope winding mechanism, the reciprocating motor can be used to drive the sprocket transmission assembly and the bidirectional threaded rod to rotate, so that the reciprocating threaded sleeve drives the limit ring to slide relatively on one side of the inside of the hanger. Since the wire rope passes through the inside of the limit ring, the wire rope can be evenly retracted and released, and the hook body will not swing back and forth, thereby improving the stability of the hook body when lifting and lowering. At the same time, by symmetrically winding the wire rope on the drum, the number of turns of the drum can be reduced when the hook body is lifted and lowered. At the same time, by setting a movable pulley sleeve and a movable pulley body on the vehicle, the stability and safety of the working process are guaranteed;

[0021] 2. By setting the hook mechanism, not only can the rotating gear plate drive the limit slider to slide inside the spiral slide groove, but also the limit slider drives the engaging sliding rod to slide inside the telescopic slide groove. When the engaging sliding rod is engaged with the fixing hole at the top of the hook rotating rod, the hook rotating rod can be fixed to avoid the phenomenon of arbitrary rotation of the hook body when lifting goods, which is not conducive to the stability of cargo lifting. When the engaging sliding rod is separated from the fixing hole at the top of the hook rotating rod, the hook body can be freely rotated, thereby controlling the lifting angle of the hook body.
