Description

Technical Field

[0001] This utility model relates to auxiliary equipment for lifting wire ropes, specifically a detachable rope guide device. Background Technology

[0002] Rope guide devices in lifting machinery are common mechanical mechanisms used to effectively guide load-bearing wire ropes and reduce their wear. Currently, a commonly used rope guide device consists of three or four rotatable guide wheels mounted on a fixed base. The wire rope passes through the central hole formed by the base hole and the three or four guide wheels. This ensures that, regardless of its swinging or sliding during operation, the wire rope remains within the central hole formed by the guide wheels, thus providing guidance.

[0003] However, if the guide pulleys become stiff, they will wear down the surface of the wire rope, eventually rendering it unusable. If the guide rope device needs to be replaced, the wire rope must first be damaged. This is because neither a pear-shaped end nor a heart-shaped loop can pass through the central hole formed by the guide pulleys; therefore, the end of the wire rope must be cut before the guide rope device can be removed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a detachable rope guide device, which adopts a separately installed base and can directly disassemble the rope guide device without damaging the wire rope.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A detachable rope guide device includes a rope guide seat on the head of a grab bucket and rope guide wheels on the rope guide seat. The rope guide seat has a rope threading hole. Three or more rope guide wheels are arranged radially and evenly around the rope threading hole, and the wheel surfaces form a rope guide channel that is directly connected to the rope threading hole. The rope guide seat is designed as two or more separate parts around the rope threading hole. The rope guide wheels are respectively disposed on the corresponding separate parts. The joints of adjacent separate parts are provided with connecting plates and are connected to each other by bolts.

[0007] The guide rope seat is designed as two separate parts, and the guide rope wheels are four of them arranged at 90° to each other and are located in pairs on the separate parts.

[0008] The guide rope seat is square and consists of two separate parts separated by a diagonal.

[0009] The guide rope seat is designed as three equally divided parts, and the guide rope wheels are three of them arranged at 120° to each other and are located on each of the divided parts.

[0010] The guide rope wheel includes a wheel frame fixed on the guide rope seat, a pin on the wheel frame, a guide rope roller mounted on the pin via a bearing, and a lubrication assembly for lubricating the bearing.

[0011] This invention discloses a detachable rope guide device. The rope guide seat is designed as a split structure and is spliced ​​and fixed to the rope guide seat by connecting plates and bolts. In this way, when the rope guide wheel is worn out, there is no need to damage the wire rope. The rope guide seat can be removed simply by disassembling it with bolts, and the rope guide wheel can be easily and quickly replaced or repaired. Attached Figure Description

[0012] The utility model will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0015] Figure 3 This is a top view of a single guide rope seat that is 45° diagonally split in half according to this utility model;

[0016] Figure 4 For along Figure 3 Schematic diagram of the cross section along line AA. Detailed Implementation

[0017] This utility model provides a detachable rope guide device, such as... Figures 1-2 As shown, it includes a rope guide seat 1 on the head of the grab bucket, and rope guide wheels 2 on the rope guide seat 1. The rope guide seat 1 has rope holes 3. Three or more rope guide wheels 2 (commonly three or four) are arranged radially evenly around the rope holes 3, and the wheel surfaces form a rope guide channel 4 that is directly connected to the rope holes 3. The wire rope 5 passes through the rope guide channel 4 and the rope holes 3 from top to bottom.

[0018] The rope guide seat 1 is welded from steel plates and adopts a split structure: it is designed as two or more separate parts centered on the rope threading hole 3, with the rope guide wheel 2 located on the corresponding separate parts (not spanning across). Connecting plates 6 are provided at the joints of adjacent separate parts, and they are connected to each other as a whole by bolts 7. Thus, when the rope guide wheel 2 is worn out, there is no need to damage the wire rope 5; simply unscrew the bolts 7 to disassemble the rope guide seat 1, and the rope guide wheel 2 can be easily and quickly replaced or repaired.

[0019] As an example, such as Figures 3-4As shown, the rope guide seat 1 is square and designed as two separate parts diagonally divided at 45°. There are four rope guide wheels 2, positioned at 90° angles to each other, forming a cross-shaped guide structure with a square rope guide channel 4 at their center. The rope guide wheels 2 are positioned in pairs on the corresponding separate parts. Each separate part has through holes 8 at three corner positions. The through hole 8 at the joint is used to install the connecting plate 6, which is then connected by bolts 7 and fixed to the upper support beam of the grab bucket below the rope guide seat 1. The other through hole 8 directly fixes the rope guide seat 1 to the upper support beam of the grab bucket using bolts 7.

[0020] As a second embodiment, the difference from the above embodiment is that the guide rope seat 1 is divided into left and right or top and bottom halves, and the four guide rope wheels 2 are X-shaped guide structures arranged at 90° to each other, and are arranged in pairs on the corresponding split parts.

[0021] As a third embodiment, the difference from the above embodiments is that the guide rope seat 1 is designed as three equally divided parts. The guide rope wheels 2 are three parts arranged at 120° to each other, and are respectively located on each of the divided parts.

[0022] In addition, each guide rope pulley 2 includes a pulley frame 9 fixed on the guide rope seat 1, a pin 10 mounted on the pulley frame 9, a guide rope roller 12 mounted on the pin 10 via a bearing 11, and a lubrication assembly for lubricating the bearing 11. The pin 10 is fixed to the pulley frame 9 by a washer 13 and a round nut 14 at one end. The bearing 11 is fixed at a suitable position in the middle of the pin 10 by two retaining rings 15 and a retaining sleeve 16. The lubrication assembly includes an oil nozzle 17 on the other end of the pin 10 and a lubrication channel 18 passing through the pin 10 to the bearing 11. The bearing 10 can be lubricated and maintained through the oil nozzle 17, extending its service life.

[0023] However, those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
