Description

Technical Field

[0001] This utility model relates to the field of mining equipment, and in particular to a winch rope arranger and a mining winch system. Background Technology

[0002] As a key piece of electromechanical equipment in coal mine production, winches are widely used in underground mines for dispatching mine cars and other auxiliary traction work, and also undertake towing, hoisting or other auxiliary handling tasks. Their working principle is to achieve traction of the object being pulled by winding and unwinding the steel wire rope wound around the drum.

[0003] In underground coal mine transportation scenarios, numerous factors contribute to frequent winch rope arrangement problems. On one hand, underground transportation distances are often long, and although the winch drum has a limited diameter and width, it must accommodate hundreds of meters of wire rope, requiring the rope to be wound in multiple layers on the drum. On the other hand, the underground working environment is complex, with narrow tunnel spaces, making it difficult to precisely align the winch installation position with the hoisting centerline, resulting in significant deviations between the winch position and the hoisting centerline, and excessively large wire rope entry angles. These combined factors prevent the wire rope from being arranged neatly and tightly on the drum as expected, leading to frequent rope tangling. Therefore, winch rope arrangers have become essential auxiliary tools to ensure the safe and efficient operation of winches. However, traditional rope arrangers have low safety levels. Firstly, traditional rope arrangers cannot determine whether the wire rope will break, thus affecting operator safety, and are insufficient to meet the actual needs of safe coal mine production. On the other hand, existing winches often rely on depth indicators to detect the lowering depth of the wire rope. The depth indicator is connected to the gearbox and does not come into direct contact with the wire rope. Moreover, the wire rope is elastic, which leads to a large error in the reading of the lowering depth of the wire rope. Furthermore, it is quite troublesome to return the reading to zero. The winch must be reversed until the winch depth indicator returns to zero. Utility Model Content

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1 The image shows a specific embodiment of the winch rope arranger provided by this utility model, which is used for, for example... Figure 3 , Figure 4 The mining winch system shown includes a rope reel 200, a drive assembly for rotating the reel 200, and a winch rope arranger 100, located on opposite sides of the reel 200. The drive assembly provides power to the reel 200 and includes a drive motor 400 and a gearbox 500 mounted on the winch base 300. The drive motor 400 provides the power source, while the gearbox 500 reduces the output speed of the drive motor 400 and increases the output torque to meet the different speed and torque requirements of the reel 200 when winding and unwinding the rope. By properly configuring the drive motor 400 and the gearbox 500, the winch can operate stably under different working conditions, ensuring that the rope winding and unwinding speed and tension meet actual working requirements, thus improving the winch's performance and safety. The winch rope arranger 100 is installed on one side of the reel 200. During the rope winding and unwinding process, it arranges the rope to ensure that the rope is neatly wound on the reel 200. By rationally arranging the winch rope arranger 100 with other parts of the winch, the winch can operate efficiently and safely during operation. The core structure of the winch rope arranger 100 consists of a rope arranging base 10 and a rope arranging assembly 20 slidably connected thereto. The rope arranging assembly 20 includes a rope arranging frame 21, on which at least one set of upper and lower corresponding rope-supporting rollers 22 and rope-pressing rollers 23 are respectively arranged. The lower rope-supporting roller 22 is rotatably connected to the rope arranging frame 21 via a pivot, allowing it to rotate flexibly during rope movement and effectively reducing frictional loss between the two. The upper rope-pressing roller 23 is mounted on a rope-pressing roller bracket 24 via a pivot, and the rope-pressing roller bracket 24 is connected to the rope arranging frame 21 via an adjustment assembly. The position of the rope-pressing roller bracket 24 relative to the rope arranging frame 21 can be adjusted via the adjustment assembly 25 to change the pressure of the rope-pressing roller 23 on the rope. A pressure sensor 60 is installed on the side of the rope laying frame 21 facing the rope pressing wheel bracket 24. It can accurately monitor the reaction force of the rope on the rope pressing wheel 23, thereby ensuring that the rope maintains a suitable tension during the rope laying process, avoiding the rope from becoming slack or overly tight, and improving the safety of the winch and the neatness of the rope laying.

[0023] In one specific embodiment, the rope-laying frame 21 is equipped with two rope-supporting rollers 22 and one rope-pressing roller 23 along the rope-threading direction, with the rope-pressing roller 23 located in the area between the two rope-supporting rollers 22. The two rope-supporting rollers 22 provide better support for the rope from below, ensuring its stability during movement, while the rope-pressing roller 23 in the middle applies appropriate pressure from above, ensuring that the rope remains in the correct position and with suitable tension as it passes through the gap between the rope-supporting rollers 22 and the rope-pressing roller 23. This layout further optimizes the constraint and guidance of the rope by the rope arranger, improving the stability and neatness of the rope arrangement, thereby enhancing the safety of the winch operation.

[0024] In one specific embodiment, the inner side of the top wall of the rope-laying frame 21 is provided with a mounting groove, and the pressure sensor 60 is detachably connected to the mounting groove of the rope-laying frame 21 using fastening bolts. This design greatly improves the convenience of installation, disassembly, and maintenance of the pressure sensor 60. More specifically, the pressure sensor 60 is a spoke-type pressure sensor 60.

[0025] Specifically, such as Figure 2As shown, the adjustment assembly 25 includes an adjustment rod 251, a section of which is tightly engaged with the pressure sensor 60 via threads. When the position of the pressure wheel 23 needs to be adjusted, the operator only needs to rotate the adjustment rod 251. Based on the threaded transmission principle, the adjustment rod 251 will be displaced in the axial direction. This displacement, through mechanical transmission, drives the pressure wheel bracket 24 and the pressure wheel 23 to move synchronously, thereby achieving high-precision adjustment of the position of the pressure wheel 23. Meanwhile, the spoke-type pressure sensor 60 adopts a unique spoke-shaped elastomer structure, which, compared to traditional column or beam sensors, has higher resistance to off-center loads and lateral forces. It can accurately capture changes in axial pressure during the process of the adjustment rod 251 being subjected to axial force, avoiding measurement deviations caused by installation errors or lateral force interference.

[0026] Specifically, the adjusting component 25 also includes a fastening component, as described in one embodiment, such as... Figure 2 As shown, the fastening assembly includes a blocking plate 252 and a fastening bolt 253. One end of the adjusting rod 251 passes through a connecting through hole located on the top wall of the rope pressing wheel bracket 24. The blocking plate 252 abuts against the inner wall of the rope pressing wheel 23. The fastening bolt 253 passes between the blocking plate 252 and the adjusting rod 251 to connect the adjusting rod 251 to the rope pressing wheel bracket 24. The blocking plate 252 abuts against the inner wall of the rope pressing wheel 23, thereby restricting the axial movement of the adjusting rod 251. The fastening bolt 253 then fixes the adjusting rod 251 to the rope pressing wheel bracket 24, thus fixing the position between the rope pressing wheel 23 and the adjusting rod 251. This ensures that the rope pressing wheel 23 always remains in the adjusted position during operation and will not be displaced due to external vibration or the force of the rope, ensuring the stability and reliability of the rope guide and further improving the safety of the winch. In other embodiments, the fastening assembly includes a fastening nut, the end of the adjusting rod 251 is provided with an external thread, the end of the adjusting rod 251 passes through the connecting through hole in the top wall of the pressure wheel bracket 24, and is fastened to the pressure wheel bracket 24 by the fastening nut.

[0027] Specifically, based on the above-described embodiments, the winch rope-laying device further includes a counting component 30. The counting component 30 includes a counting bracket 31 and a speed counter 32 mounted on the counting bracket 31. The counting bracket 31 is connected to the rope-pressing wheel bracket 24. The rotating shaft of the speed counter 32 is fixedly connected to the pivot shaft of the rope-pressing wheel 23 via a connecting sleeve. When the rope-pressing wheel 23 rotates with the movement of the rope, its pivot shaft drives the rotating shaft of the speed counter 32 to rotate synchronously. The speed counter 32 can record the number of rotations and the rotation speed of the rope-pressing wheel 23 in real time. Through this data, information such as the rope-laying speed and the rope length can be indirectly obtained. Based on the data fed back by the counting component 30, operators can promptly grasp the rope-laying situation. When abnormalities are detected, such as excessively fast or slow rope-laying speed, or rope length not meeting expectations, timely adjustments can be made, effectively avoiding safety problems caused by abnormal rope-laying and further improving the safety and reliability of the winch. Specifically, in one optional embodiment, the rope-laying assembly 20 is slidably connected to the rope-laying base 10 via a lead screw and nut mechanism 40. Specifically, the rope-laying base 10 is rotatably connected to a reciprocating lead screw 41 extending along a first direction and at least one guide rail 51. The rope-laying frame 21 is provided with a nut connecting sleeve 211 and a sliding connecting sleeve 212. The nut connecting sleeve 211 is sleeved on a nut that cooperates with the lead screw, and the sliding connecting sleeve 212 is sleeved on the guide rail 51.

[0028] When the reciprocating screw 41 rotates, the nut that mates with the screw 41 moves along the axial direction of the screw 41. Since the nut connecting sleeve 211 is fitted onto the nut, the rope-laying frame 21 moves along with the nut. Simultaneously, the sliding connecting sleeve 212 slides on the guide rail 51, guiding the movement of the rope-laying frame 21 and ensuring that it moves smoothly and accurately along the first direction. This connection method enables the rope-laying assembly 20 to achieve precise linear reciprocating motion on the rope-laying base 10, ensuring that the rope is evenly and neatly arranged on the winch drum, avoiding problems such as rope tangling and overlapping, and greatly improving the quality and safety of winch rope laying. Specifically, a chain drive assembly 600 is provided between the winch rope arranger 100 and the reel 200. One sprocket of the chain drive assembly 600 is connected to the lead screw 41 of the winch rope arranger 100, and the other sprocket is connected to the central shaft of the reel 200. When the reel 200 rotates, power is transmitted to the lead screw 41 through the chain drive assembly 600, causing the lead screw 41 to rotate, which in turn drives the rope arrangement assembly 20 to move on the rope arrangement base 10, realizing automatic rope arrangement. The chain drive assembly 600 can be an integral drive chain group or a segmented drive chain to achieve transmission. It has the advantages of high transmission efficiency, accurate transmission ratio, and compact structure. It can ensure stable and reliable power transmission between the winch rope arranger 100 and the reel 200, improve the automation level and working efficiency of winch rope arrangement, and further enhance the safety and reliability of winch use.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
