Description

Technical Field

[0001] The utility model relates to the technical field of hoists, and particularly relates to a rope splitter and a hoist. Background Art

[0002] A hoist generally refers to a mechanical device with relatively large power and strong lifting capacity. In the building decoration industry, it is often installed on a hanging basket. The pressing wheel mechanism presses the steel wire rope tightly on the V-shaped groove of the internal gear disk to generate sufficient friction to drive the hanging basket on the steel wire rope to move up and down.

[0003] The hoist installed on the hanging basket is different from the common winding hoist. Only one turn of the steel wire rope is tied to the gear disk. When the internal gear disk rolls along the steel wire rope, it is very easy to cause mutual wear on the surface of the steel wire rope. At the same time, due to the long-term action of the traction force on the steel wire rope, plastic deformation occurs. The interaction of the two will cause the steel wire to gradually become longer and thinner, seriously shortening the service life of the steel wire rope. Content of the Utility Model

[0004] Therefore, the utility model provides a rope splitter and a hoist to solve the problem that the service life of the steel wire rope is shortened due to the mutual wear on the surface of the steel wire rope in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] According to the first aspect of the utility model,

[0007] The utility model discloses a rope splitter, which is installed on the wire reel of a hoist and includes:

[0008] A main body member, with a wire inlet groove provided on one side and a wire outlet groove provided on the other side;

[0009] A rope splitting plate, with the front side inserted into the wire groove of the wire reel and the rear side connected to the outside of the wire outlet groove. The rope splitting plate is located between the wire inlet groove and the wire outlet groove;

[0010] Wherein, an inlet wire cover plate is provided on the front surface of the main body member, and an outlet wire cover plate is provided on the reverse surface. The inlet wire cover plate and the outlet wire cover plate are used to prevent the steel wire rope from slipping out of the main body member.

[0011] Further, a pre-tightening hole is respectively provided at both ends of the main body member. A fastener is inserted into the pre-tightening hole and is adapted to fix the inlet wire cover plate and the outlet wire cover plate to the hoist through tightening.

[0012] Further, the rope splitting plate is integrally connected with the main body member, and a ceramic wear-resistant layer is covered on the rope splitting plate.

[0013] Further, the main body member is a metal casting, and reinforcing ribs are provided inside the main body member.

[0014] According to the second aspect of the present utility model

[0015] The present utility model discloses a hoist, which includes the rope dividing device proposed above, and includes:

[0016] A wire reel, with an arc-shaped guard ring arranged on the outside. One end of the guard ring is connected to the rope dividing device, and the other end is connected to the rope pressing device. The upper end of the rope dividing device is connected to the rope inlet pipe, and the lower end is connected to the rope outlet pipe;

[0017] A speed reducer, with a motor arranged at the input end and driving the wire reel to rotate at the output end, and the speed reducer is arranged inside the wire reel.

[0018] Further, the speed reducer includes:

[0019] An internal gear ring, arranged inside the wire reel, and the internal gear ring is in meshing transmission connection with a transmission gear;

[0020] A transmission shaft, with one end coaxially and transmission-connected to the transmission gear and the other end coaxially and transmission-connected to a worm gear. The worm gear is in meshing transmission connection with a worm shaft installed with a motor.

[0021] Further, the speed reducer is a planetary gear speed reducer.

[0022] Further, the speed reducer is a brake motor.

[0023] The present utility model has the following advantages:

[0024] The rope dividing device disclosed by the present utility model is an integrally formed metal casting, with a solid structure and good wear resistance. It can effectively separate the steel wire ropes from the wire reel, prevent them from contacting and wearing each other, and avoid the problem of shortening the service life of the steel wire ropes. At the same time, the rope dividing device can also be well adapted to the hoist, thereby alleviating the situation of the steel wire ropes being coiled and wound. On this basis, the present utility model also discloses a hoist. By using a worm and worm gear to complete the first-stage deceleration, and then using gear meshing to complete the second-stage deceleration, the output power of the hoist is significantly improved, and the working load of the motor is reduced.

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] Please refer to Figures 1-5, the present utility model discloses a rope separator, which is installed on the wire reel of a hoist, and its main structure includes a main body member a1 and a rope separating plate a5. Among them, the main body member a1 is a structural member formed by metal casting or integral die forging, and in order to improve the structural strength of the main body member a1, reinforcing ribs a6 are also provided at the edge of the main body member a1. The outer shape of the main body member a1 is arc-shaped so as to fit with the wire reel. And, an inlet wire groove a3 is provided on one side of the main body member a1, and an outlet wire groove a2 is provided on the other side. The inlet wire groove a3 and the outlet wire groove a2 are separated from each other, thereby avoiding mutual contact and wear of the steel wire ropes. And a rope separating plate a5 is provided at the position between the inlet wire groove a3 and the outlet wire groove a2, and the front side of the rope separating plate a5 is inserted into the wire groove of the wire reel, and the rear side is connected to the outside of the outlet wire groove a2. Thus, the steel wire rope can be guided into the outlet wire groove a2 by the arc-shaped outer edge on the front side of the rope separating plate a5, so as to achieve the purpose of isolating the steel wire ropes and preventing mutual contact and wear by using the rope separator.

[0038] Specifically, on this basis, as Figure 5 , the rope separating plate a5 can be integrally connected to the main body member a1 by welding, and in order to improve the durability of the rope separating plate a5, a ceramic wear-resistant layer mainly composed of silicon oxide or aluminum oxide is covered on the rope separating plate a5.

[0039] In this embodiment, as Figure 3 , an inlet wire cover plate a4 is provided on the front side of the main body member a1, and an outlet wire cover plate a7 is provided on the reverse side. The inlet wire cover plate a4 and the outlet wire cover plate a7 are used to prevent the steel wire rope from coming out of the main body member a1.

[0040] In a specific embodiment disclosed by the present utility model, a pre-tightening hole a8 is respectively provided at both ends of the main body member a1. A fastener is inserted into the pre-tightening hole a8 and is adapted to fix the inlet wire cover plate a4 and the outlet wire cover plate a7 to the hoist by tightening.

[0041] Based on the same inventive concept, the present utility model discloses a hoist, which includes the rope separator as described above. Its structure includes a wire reel b1 and a speed reducer b3. Among them, as Figures 6-7 , a groove for embedding the steel wire rope is provided on the outer edge of the wire reel b1, and an arc-shaped retaining ring b4 is provided outside the groove. The arc-shaped retaining ring b4 is used to prevent the steel wire rope from coming out of the groove of the wire reel b1. In addition, the rope separator is connected to one end of the arc-shaped retaining ring b4, and the other end of the arc-shaped retaining ring b4 is connected to a rope pressing device b5. The rope pressing device b5 can press the steel wire rope into the groove of the wire reel b1, and utilize the friction force between the wire reel b1 and the steel wire rope to achieve the effect of lifting the hanging basket. And the upper end of the rope separator is also connected to an inlet rope pipe b2, and the lower end is connected to an outlet rope pipe b6, thereby enabling the steel wire rope to flow between the inlet rope pipe b2 and the outlet rope pipe b6.

[0042] In this embodiment, as Figure 7, the wire reel b1 is drivingly connected to the output end of the speed reducer b3. The input end of the speed reducer b3 is provided with a motor, and the speed reducer b3 can be arranged inside the wire reel b1. Specifically, the speed reducer b3 includes an internal gear ring b31 and a transmission shaft b33. The internal gear ring b31 is arranged inside the wire reel b1, and the internal gear ring b31 is drivingly connected to the transmission gear b32 in a meshing manner. The transmission gear b32 is drivingly connected to the worm wheel b34 coaxially through the transmission shaft b33. The worm wheel b34 is drivingly connected to the worm b35 equipped with a motor in a meshing manner. In this embodiment, since the worm and worm wheel mechanism has self-locking property, an ordinary motor can be selected for the motor.

[0043] In some embodiments, the speed reducer b3 is a planetary gear speed reducer. Moreover, the sun gear of the planetary gear speed reducer is drivingly connected to the motor coaxially and drives the internal gear ring b31 to rotate through the planetary gears. In this embodiment, the motor is a brake motor to prevent the wire reel b1 from being out of control.

[0044] Although the present utility model has been described in detail with general descriptions and specific embodiments above, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
