Description

Technical Field

[0001] The utility model relates to the technical field of pulley lifting tools, in particular to a pulley device with a guide rope mechanism. Background Art

[0002] Lifting pulleys are essential lifting tools. They offer a simple structure and are easy to use. They can repeatedly change the direction of the traction cable between the pulley and the block assembly, and can lift or move moving objects. In particular, pulley blocks composed of a combination of pulleys are widely used in construction and installation operations, in conjunction with winches, masts, or other lifting machinery. Existing pulleys often lack a dedicated rope guide mechanism, which can cause the rope to deviate from its track during operation and rub against the pulley's wallboard, resulting in excessive wear and even breakage of the rope, affecting safety and service life. Utility Model Content

[0003] The purpose of the present utility model is to provide a pulley device with a guide rope mechanism in order to solve at least one of the above technical problems.

[0004] In the first aspect, an embodiment of the utility model provides a pulley device with a rope guide mechanism, comprising: a lifting pulley and a rope guide mechanism; the rope guide mechanism comprises a bar-shaped body, through holes are respectively provided at both ends of the bar-shaped body, and a bolt hole is provided in the middle of the bar-shaped body; the middle part of the rope guide mechanism is fixed to the top rope outlet position of the lifting pulley by a fixing bolt; the guide rope of the lifting pulley is provided through the through hole.

[0005] Furthermore, the guide rope mechanism is made of reinforced nylon.

[0006] Furthermore, the penetration direction of the through hole and the penetration direction of the bolt hole are not perpendicular to each other.

[0007] Furthermore, the spacing between the through holes at both ends of the strip-shaped body matches the spacing between the guide ropes at the rope outlet end of the lifting pulley.

[0008] Furthermore, the through hole includes a circular through hole.

[0009] Furthermore, a pair of upper latching keys are provided on the side surface of the strip-shaped body at both sides of the bolt hole, and the upper latching keys are latched at the top edge of the wall panel of the lifting pulley.

[0010] The utility model provides a pulley device with a rope guide mechanism. The rope guide mechanism is arranged on the top of the lifting pulley, which can maintain the position of the guide rope, reduce the friction between the guide rope and the wall panel of the lifting pulley, and prevent the guide rope from deflecting during use. A pair of upper locking keys arranged on the side of the strip body are clamped at the top edge position of the wall panel of the lifting pulley, which can prevent the rope guide mechanism from deflecting as the guide rope slides, ensure that the guide rope passes through the through hole as vertically as possible, improve the smoothness and safety of the use of the pulley device, extend the service life of the guide rope, and alleviate the technical problems of rope wear and deviation existing in traditional pulleys.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Figure 1 Schematic diagram of a pulley device with a guide rope mechanism according to an embodiment of the present invention. Figure 1As shown, the device comprises a hoisting block 1 and a guide rope mechanism 2.

[0019] Figure 2 is a top view of a guide rope mechanism according to an embodiment of the present application, Figure 3 is a side view of a guide rope mechanism according to an embodiment of the present application, Figure 4 is a front view of a guide rope mechanism according to an embodiment of the present application.

[0020] As shown, Figure 2-Figure 4 the guide rope mechanism 2 comprises a strip-shaped body 21, through holes 22 are arranged at both ends of the strip-shaped body 21 respectively, and a bolt hole 23 is arranged in the middle of the strip-shaped body 21. Among them, the through direction of the through hole 22 and the through direction of the bolt hole 23 are perpendicular.

[0021] Specifically, as shown, Figure 1 the middle part of the guide rope mechanism 2 is fixed to the top rope outlet end position of the hoisting block 1 through a fixing bolt 3; and the guide rope 4 of the hoisting block 1 passes through the through hole 22.

[0022] Specifically, as shown, Figure 1-Figure 3 a pair of upper clamping keys 24 are arranged on the side surface of the strip-shaped body 21 at positions on both sides of the bolt hole 23, and the upper clamping keys 24 are clamped at the top edge position of the wallboard of the hoisting block 1.

[0023] Specifically, the inclination angle of the upper clamping key 24 is consistent with the inclination direction of the top edge of the wallboard of the hoisting block 1, and the inclination directions of the upper clamping keys 24 on the left and right sides are opposite, so that the upper clamping key 24 can be clamped at the top edge of the wallboard of the hoisting block 1 to ensure that the guide rope mechanism 2 does not relatively deflect with the hoisting block 1.

[0024] In the embodiment of the present application, by arranging the upper clamping key 24 on the side surface of the guide rope mechanism 2, it can prevent the guide rope 4 from deflecting together with the guide rope mechanism 2 when sliding through the through hole 22, ensure that the guide rope 4 passes through the through hole 22 as vertically as possible, and fix the relative position of the guide rope mechanism 2 and the hoisting block 1, so that the guide rope 4 can pass through the through hole 22 more smoothly.

[0025] Preferably, as shown, Figure 2 the through hole 22 comprises a circular through hole, and the cross section of the guide rope 4 is circular.

[0026] Specifically, the spacing between the through holes 22 at both ends of the strip-shaped body 21 matches the spacing of the guide rope 4 at the rope outlet end of the hoisting block 1.

[0027] In an optional implementation manner of the embodiment of the present application, the material of the guide rope mechanism 2 is reinforced nylon, so as to reduce the friction to the maximum extent.

[0028] As can be seen from the above description, the embodiment of the present invention provides a pulley device with a rope guide mechanism, which has the following technical effects compared with the prior art:

[0029] (1) Effectively prevent the guide rope from deviating from the pulley track of the lifting pulley;

[0030] (2) Extend the service life of the guide rope and reduce the wear between the guide rope and the lifting pulley wall plate;

[0031] (3) Improved overall operational safety and efficiency, making use smoother.
