Description

Technical Field

[0001] This utility model relates to a wire rope arrangement device, belonging to the field of engineering machinery technology. Background Technology

[0002] Rope winders are core devices in the field of mechanical engineering used to guide the orderly arrangement of wire ropes. They achieve standardized winding of wire ropes through a spiral groove structure or guide rail system. Their core function is to prevent mechanical failures such as rope slippage and compression deformation caused by disorder and overlap of the wire rope. They are widely used in electric hoists, winches, lifting equipment, and high-speed braiding machines.

[0003] Existing rope arrangers come in various types and forms depending on the specific needs of the field; common types include forced standard rope arrangers, horizontal axis free sliding rope arrangers, and inclined axis free sliding rope arrangers. However, each of the above types of rope arrangers has its own technical defects, which often result in broken wires and tangled ropes, reducing the service life of the wire rope and adversely affecting engineering construction. Specifically, the forced-standard rope winding device can theoretically guarantee regular multi-layer winding of the wire rope; however, it requires high manufacturing precision, transmission errors are easy to accumulate, and significant rope misalignment will occur after a period of use; furthermore, it is not suitable for large winches. Free-sliding rope arrangers utilize the winding motion of steel wire rope to drive a rope-arranging pulley to slide back and forth on a fixed rope-arranging shaft to arrange the rope. This type of rope arranger is simple in structure and inexpensive, but its effectiveness in assisting rope winding is relatively poor. There are also inclined shaft free-sliding rope arrangers, which use the winding motion of the wire rope to drive the rope arrangement pulley to slide back and forth on the rope arrangement shaft that is inclined at a certain angle to the axis of the zigzag rope groove drum. This rope winding method is difficult to control and has a certain impact on stability. The inclined shaft may also get stuck and the angle cannot be changed, which will increase the rope entry angle during winding and cause more serious damage to the wire rope. At the same time, these types of rope arrangers cannot achieve automatic rope arrangement adjustment and have low rope arrangement efficiency. Utility Model Content

[0004] In view of the technical problems existing in the above-mentioned wire rope winding device, the purpose of this utility model is to provide a wire rope winding device that can automatically wind the rope by the lifting mechanism winding and unwinding the rope and the speed change of the load weight, so as to ensure that the lifting rope does not get tangled and thus extend the service life of the wire rope.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wire rope arranging device, comprising a deflection mechanism, wherein the deflection mechanism comprises a rope arranging pulley assembly, a rope arranging shaft, a horizontal shaft, two parallel side plates connected to both ends of the horizontal shaft as a single unit, a bearing seat, a rope arranging shaft adapter block, a clamp, and bolts; the two parallel side plates of the deflection mechanism are respectively connected to the bearing seat by bolts, and the two ends of the rope arranging shaft are connected to the rope arranging shaft adapter blocks, and the outer ends of the two rope arranging shaft adapter blocks are respectively provided with adapter block bosses, which are rotatably connected to the bearing seat; the rope arranging pulley assembly is sleeved on the rope arranging shaft, and the rope arranging pulley assembly rotates and slides on the rope arranging shaft; Furthermore, one end of each of the two parallel side plates is connected to a horizontal axis, and the other end is provided with a side plate bolt hole; the tile seat is provided with a tile seat bolt hole, and the parallel side plates and the tile seat are connected together by bolts passing through the side plate bolt holes and the tile seat bolt holes; Furthermore, the two bearing centers are located on the same horizontal line and the line connecting the two bearing centers is parallel to the horizontal axis; Furthermore, the rope-laying shaft adapter blocks at both ends of the rope-laying shaft are set with an off-axis structure, and the axis of the adapter block boss is set concentrically with the axis of the bearing seat. Furthermore, the rope-laying shaft adapter block has a C-shaped opening design with bolt holes at the opening. In use, the rope-laying shaft is clamped in the C-shaped opening and then secured by bolts passing through the bolt holes of the adapter block. The C-shaped openings of the two rope-laying shaft adapter blocks at both ends of the rope-laying shaft face opposite directions. Because the rope-laying shaft adapter blocks are off-axis and the two C-shaped openings are opposite, the axial centerline of the rope-laying shaft forms an angle with the centerline connecting the two bearing seats. This angle makes the rope-laying shaft form an inclined axis of the rope-laying device. Furthermore, a clamp is installed on each of the rope-laying shafts on both sides of the rope-laying pulley assembly, and the two clamps are locked in two set positions on the rope-laying shaft; Furthermore, the rope-laying pulley assembly includes two vertical clamping plates, a rope-blocking rod connecting the two vertical clamping plates, and a rope-laying pulley; the rope-laying pulley is located in the space between the two vertical clamping plates, and a rope groove is provided around the outer diameter of the rope-laying pulley; two horizontally parallel rope-blocking rods are fixedly connected between the two vertical clamping plates located above the rope-laying pulley; the rotation plane of the rope-laying pulley is perpendicular to the axis of the rope-laying shaft.

[0006] Furthermore, a set of baffles is horizontally arranged at one end away from the vertical clamping plate in the direction of the through hole. The two baffles are connected to the vertical clamping plate of the rope pulley assembly. The horizontal axis of the deflection mechanism is located between the two baffles, and there is a gap between the horizontal axis and the set of baffles. Furthermore, the baffle is designed with a V-groove structure; The aforementioned deflection mechanism is mounted on a support frame, the bottom of which is fixed to a bottom platform. A lifting mechanism is installed on the bottom platform at a position diagonally below the deflection mechanism. The support frame is symmetrically distributed on both sides, with the deflection mechanism connected to the top of each side. Furthermore, a drum is provided at one end of the lifting mechanism, and the drum serves as the final actuator for power transmission. In this design, the motor drives the drum to rotate via a reducer, and the lifting and lowering of the load are achieved by tightening or loosening the wire rope. The load force is transmitted through the wire rope and ultimately controlled by the drum. The rope winding device acts as a guide to ensure that the wire rope does not become tangled throughout the process.

[0007] The beneficial effects of this rope-laying device are: This rope-laying device is suitable for rope-laying methods where the rope exits from the rear of the hoisting mechanism drum. After the wire rope is drawn out from the hoisting mechanism drum, it is wound into the rope groove of the rope-laying pulley and then exits from the rope groove. Automatic rope laying is achieved by the hoisting mechanism's rope winding and unwinding, and by the weight and speed changes of the load. This solves the problem of tangled ropes at its source, greatly extends the service life of the wire rope, and improves the efficiency of rope laying. Attached Figure Description

Detailed Implementation

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] like Figure 1-3The diagram shows a wire rope arrangement device, including a deflection mechanism. The deflection mechanism includes a rope arrangement pulley assembly, a rope arrangement shaft 3, a horizontal shaft 4, two parallel side plates 5 connected to both ends of the horizontal shaft 4 as a single unit, a bearing seat 6, a rope arrangement shaft adapter block 7, a clamp 8, and bolts 9. The two parallel side plates 5 of the deflection mechanism are respectively connected to the bearing seat 6 by bolts 9. The two ends of the rope arrangement shaft 3 are connected to the rope arrangement shaft adapter blocks 7. The outer ends of the two rope arrangement shaft adapter blocks 7 are respectively provided with adapter block bosses 7-1. The adapter block bosses 7-1 are rotatably connected to the bearing seat 6. The rope arrangement pulley assembly is sleeved on the rope arrangement shaft 3, and the rope arrangement pulley assembly rotates and slides on the rope arrangement shaft 3. Furthermore, one end of each of the two parallel side plates 5 is connected to the horizontal shaft 4, and the other end is provided with a side plate bolt hole 5-1; the tile seat 6 is provided with a tile seat bolt hole 6-1, and the parallel side plates 5 and the tile seat 6 are connected together by bolts 9 passing through the side plate bolt hole 5-1 and the tile seat bolt hole 6-1; Furthermore, the two bearing seats 6 have their axes aligned on the same horizontal line, and the line connecting the two bearing seats 6 have their axes parallel to the horizontal axis 4. Furthermore, the rope shaft adapter blocks 7 at both ends of the rope shaft 3 are set with an off-axis structure, and the axis of the adapter block boss 7-1 is set concentrically with the axis of the bearing seat 6. Furthermore, the rope-laying shaft adapter block 7 has a C-shaped opening design, with adapter block bolt holes 7-2 at the opening. In use, the rope-laying shaft 3 is clamped in the C-shaped opening and then secured by bolts passing through the adapter block bolt holes 7-2. The C-shaped openings of the two rope-laying shaft adapter blocks 7 at both ends of the rope-laying shaft 3 are in opposite directions. Since the rope-laying shaft adapter block 7 is off-axis and the two C-shaped openings are opposite, the axial center line 10 of the rope-laying shaft forms an angle with the center line 11 connecting the two bearing seats. This angle makes the rope-laying shaft 3 form an inclined axis of the rope-laying device. In the above structure, the rotation of the rope shaft 3 is based on the center line 11 connecting the two tile seats, rather than rotating around the axial center line 10 of the rope shaft itself.

[0014] Furthermore, a clamp 8 is provided on each of the rope shafts 3 on both sides of the rope pulley assembly. The two clamps 8 are locked in the set position of the rope shaft 3 to prevent the rope pulley 14 from exceeding the limit set position due to the vibration of the wire rope.

[0015] Furthermore, the rope-laying pulley assembly includes two vertical clamping plates 12, a rope-blocking rod 13 connecting the two vertical clamping plates 12, and a rope-laying pulley 14; the rope-laying pulley 14 is located in the space between the two vertical clamping plates 12, and a rope-laying pulley groove 14-1 is provided around the outer diameter of the rope-laying pulley 14; two horizontally parallel rope-blocking rods 13 are fixedly connected between the two vertical clamping plates 12 located above the rope-laying pulley 14; the rotation plane of the rope-laying pulley 14 is perpendicular to the axis of the rope-laying shaft 3.

[0016] Furthermore, a set of baffles 15 is horizontally arranged at one end away from the through hole direction of the vertical clamping plate 12. The two baffles 15 are connected to the vertical clamping plate 12 of the rope pulley assembly. The horizontal shaft 4 of the deflection mechanism is located between the two baffles 15 and there is a gap between the horizontal shaft 4 and the set of baffles 15. The horizontal shaft 4 described above essentially functions as a guide rod. The two baffles 15 are inserted into the horizontal shaft 4. During the movement of the rope-laying shaft 3, when the two baffles 15 are located at the center of the horizontal shaft 4, the baffles 15 remain perpendicular to the horizontal shaft 4. When the rope-laying pulley 14 slides to the left to the clamp position or to the right to another clamp position on the rope-laying shaft 3, the baffles 15 form an angle with the horizontal shaft 4 and are not perpendicular. Furthermore, the baffle 15 is designed with a V-groove structure. As the rope-laying pulley 14 slides back and forth on the rope-laying shaft 3, the horizontal shaft 4 contacts one side of the V-groove of the lower baffle 15 or the middle line of the V-groove. This structural design essentially allows the rope-laying pulley assembly (vertical clamp 12, rope-blocking rod 13, rope-laying pulley 14) to move freely within a certain range. This ensures that when the wire rope 17 of the rope-laying pulley groove 14-1 applies a force to the rope-laying pulley 14, the rope-laying pulley 14 can move in any posture according to the mechanical principle, thereby realizing rope laying. The aforementioned deflection mechanism is mounted on the support 1, the bottom of the support 1 is fixed on the bottom platform 2, and a lifting mechanism is installed on the bottom platform 2 at a position diagonally below the deflection mechanism; the support 1 is symmetrically distributed on the left and right and the deflection mechanism is connected to the top positions on both sides. Furthermore, a drum 16 is provided at one end of the lifting mechanism, which serves as the final actuator for power transmission.

[0017] The rope-laying device of this scheme is suitable for the rope-laying method of the hoisting mechanism drum 16 exiting the rope. The rope-laying device needs to be used in conjunction with the drum 16 and the rope-passing pulley. Its installation structure is as follows: bracket 1, drum 16, rope-passing pulley fixing device. The rope-passing pulley is fixed by the rope-passing pulley fixing device. The drum 16 is located below the side of the rope-laying pulley assembly, and the rope-passing pulley is located above the side of the rope-laying pulley assembly. The drum 16 and the rope-passing pulley are both located on the side away from the rope-laying shaft 3. The rotation shafts of the drum 16, the rope-passing pulley, and the rope-laying pulley 14 in the rope-laying pulley assembly are arranged in parallel.

[0018] In practice, after the wire rope 17 is drawn out from the drum 16, it passes through the rope groove 14.1 of the rope-laying pulley and then exits from the rope groove of the passing pulley. The rope-laying pulley 14 divides the wire rope 17 between the drum 16 and the passing pulley into two segments of different lengths. Under the axial resultant force of the two segments of wire rope, the rope-laying pulley assembly moves back and forth on the rope-laying shaft 3 as the wire rope 17 is wound on the drum 16. Each time the rope-laying pulley 14 passes the midpoint of the rope-laying shaft 3, the deflection direction changes. As the winding continues, the rope-laying pulley 14 moves to the clamp position at one end of the rope-laying shaft 3. The rope-laying pulley 14 moves back and slowly returns to the midpoint of the rope-laying shaft 3, then moves past the midpoint and continues to the clamp position at the other end of the rope-laying shaft 3. As the winding of the wire rope 17 continues, the rope-laying pulley 14 repeats the above sliding trajectory, thus repeatedly circulating the rope.
