Description

Technical Field

[0001] The utility model relates to the field of hoisting, in particular to an anti-dropping hoisting tool. Background Art

[0002] During the operation of a sucker crane, due to the swing of the hanging beam, the steel wire rope is likely to come out of the groove. In daily work, this situation occurs multiple times a month, at least once a week on average, with a relatively high frequency. And each time it takes half an hour for workers to handle it, which not only delays the turning and transporting of billets, but also causes the steel wire rope to wear out and be scrapped, damages the equipment, increases the maintenance cost, and affects the safe hoisting.

[0003] How to keep the steel wire rope stable in the groove is the problem to be solved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-dropping hoisting tool, which solves the problem that the steel wire rope is easy to fall off.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] The utility model provides an anti-dropping hoisting tool, including a rotating mechanism and a frame. The rotating mechanism is rotatably arranged on the frame.

[0007] The rotating mechanism includes a rotating shaft, a pulley and a rope body. The rotating shaft is rotatably arranged on the frame. The pulley is arranged on the rotating shaft. The rope body is sleeved on the outer periphery of the pulley.

[0008] A guard bar is arranged on the frame. The guard bar is located at the outer edge of the outer periphery of the pulley. The rope body is located between the pulley and the guard bar. The guard bar encloses the rope body.

[0009] Optionally, a reinforcing disc is further arranged on the rotating shaft. The reinforcing disc is located between two adjacent pulleys.

[0010] Optionally, a limiting groove is arranged on the guard bar. The outer periphery of the rotating shaft is located in the limiting groove.

[0011] Optionally, a first connecting rod and a second connecting rod are respectively arranged at both ends of the guard bar. The first connecting rod and the second connecting rod jointly clamp the guard bar.

[0012] Optionally, the guard bar is arranged parallel to the rotating shaft.

[0013] Optionally, a first side plate and a second side plate are respectively arranged on both sides of the frame. The rotating shaft is rotatably arranged on the first side plate and the second side plate.

[0014] Due to the application of the above technical scheme, the utility model has the following advantages compared with the prior art:

[0015] A kind of anti - shedding hoisting tool of the utility model. Since the rope body is between the pulley and the guard rod, and the guard rod encloses the rope body, when the frame swings during the ascending or descending process of the frame, the swinging of the rope body is restricted by the guard rod. In this way, the rope body is not easily shed from the pulley, thus solving the problem that the steel wire rope is easily shed. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0024] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] As Figure 1 and Figure 2 and Figure 3 shown, the anti-drop hoisting tool includes a rotating mechanism 1 and a frame 2. The rotating mechanism 1 is arranged on the frame 2. The rotating mechanism 1 includes a rotating shaft 11, a pulley 12 and a rope body 13. The rotating shaft 11 is rotatably arranged on the frame 2. The pulley 12 is arranged on the rotating shaft 11. The pulley 12 is fixed together with the rotating shaft 11. The rope body 13 is sleeved on the outer periphery of the pulley 12.

[0027] Both ends of the upper part of the rope body 13 are sleeved on other equipment. The rope body 13 can rise or fall. Therefore, the whole rotating mechanism 1 can rise or fall. Correspondingly, the frame 2 can rise or fall. There is a groove 15 on the outer periphery of the pulley 12. The rope body 13 is sleeved in the groove 15. In this example, the rope body 13 is a steel wire rope.

[0028] A guard rod 3 is arranged on the frame 2. The guard rod 3 is located on the outer edge of the outer periphery of the pulley 12. The guard rod 3 does not contact the pulley 12. The rope body 13 is located between the pulley 12 and the guard rod 3. The rope body 13 does not contact the guard rod 3. And the guard rod 3 encloses the rope body 13. Only when the rope body 13 swings and is about to fall off from the groove 15, the guard rod 3 will block the rope body 13 to prevent the rope body 13 from falling off from the groove 15.

[0029] A reinforcing disc 14 is also arranged on the rotating shaft 11. Multiple pulleys 12 can be arranged. The reinforcing disc 14 is located between two adjacent pulleys 12. Multiple reinforcing discs 14 can also be arranged, which is to strengthen the rotating shaft 11 so that the rotating shaft 11 can bear a heavier weight and prevent the middle of the rotating shaft 11 from bending.

[0030] A limiting groove 30 is arranged on the guard rod 3. The outer periphery of the pulley 12 is located in the limiting groove 30. The number of the limiting grooves 30 is matched with the number of the pulleys 12. Two guard rods 3 are symmetrically arranged on both sides of the frame 2. The pulley 12 is located between the two guard rods 3. Limiting grooves 30 are arranged on both of the two guard rods 3.

[0031] At both ends of the frame 2, a first connecting rod 31 and a second connecting rod 32 are respectively arranged. The first connecting rod 31 and the second connecting rod 32 jointly clamp the guard rod 3, and the first connecting rod 31 and the second connecting rod 32 can also support the guard rod 3.

[0032] The guard rod 3 is arranged parallel to the rotating shaft 11, and the guard rod 3 is in the same direction as the extending direction of the rotating shaft 11.

[0033] On both sides of the frame 2, a first side plate 21 and a second side plate 22 are respectively arranged. The rotating shaft 11 is rotatably arranged on the first side plate 21 and the second side plate 22. Both the first side plate 21 and the second side plate 22 are narrower at the top and wider at the bottom, which is beneficial for the first side plate 21 and the second side plate 22 to jointly support the rotating shaft 11.

[0034] In addition, the first connecting rod 31 is connected to the first side plate 21, the second connecting rod 32 is connected to the second side plate 22, and the first connecting rod 31 and the second connecting rod 32 have the same height.

[0035] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
