Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a multi-layer winding drum rope arrangement device. Background Art

[0002] With the rapid development of engineering fields such as marine engineering, port transportation, mining engineering and hydropower station construction, the demand for various ultra-large lift lifting equipment is increasing. For example, the lifting height of a 1,500-ton gantry crane is 108 meters, and the rope capacity of the drum used by the gantry crane is 1,100 meters. The rope capacity of the drum used to lift an unmanned submersible with a maximum working depth of 4,000 meters is as high as 4,500 meters. In the face of these large-lift and large-rope-capacity projects, if the drum adopts a single-layer winding method, the rope capacity of the wire rope is increased by increasing the drum diameter and the drum length, and its effect is limited. If the wire rope capacity of the drum needs to be greatly increased, a multi-layer winding drum must be used.

[0003] During the operation of the multi-layer winding drum, it will rotate forward or reverse to wind the wire rope or output the wire rope, and at the same time, a guide pulley is required to traction and guide the wire rope. In order to avoid the phenomenon of tangled ropes and cause operation failures, when the wire rope is arranged on the drum through the guide pulley, the wire rope exit angle and the wire rope entry angle need to be less than a certain angle. In order to ensure that the rope exit angle and the rope entry angle are less than a certain angle, a certain distance needs to be maintained between the drum and the guide pulley when the drum is designed. In order to avoid spatial interference with the shaking wire rope, other mechanisms or equipment cannot be arranged in the space of the spacing, resulting in a waste of overall layout space. In addition, after the first layer of wire rope is arranged, the remaining layers of wire rope must be arranged. However, due to the lack of rope groove restrictions and the coating of lubricating oil on the wire rope, the wire rope is arranged on the drum through the guide pulley. During the angle change, it is very easy to cause tangled ropes, ropes falling off or rope climbing. Utility Model Content

[0044] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0045] In order to facilitate the understanding of the technical solution of the present utility model, the technical problem to be solved by the present utility model is first described.

[0046] refer to Figure 1 , Figure 1 Schematic diagram of the structure of a multi-layer winding drum rope arrangement device in some embodiments. Figure 1As shown, the multi-layer winding drum 100 includes a first end and a second end that are relatively arranged. Taking the winding wire rope 101 as an example, when winding the wire rope 101, the multi-layer winding drum 100 rotates forward, so that the wire rope 101 is wound from the first end of the multi-layer winding drum 100 to the second end, and after the first circle is wound, it is wound from the second end to the first end, and the cycle is repeated until the winding operation is completed. When the wire rope 101 is reversed and output, the process is opposite. In the above operation process, the pulley 102 is required to pull and guide the wire rope 101. In order to avoid the phenomenon of tangled ropes, when the wire rope 101 is arranged on the drum through the pulley 102, the angle α between the starting and ending positions of the wire rope 101 and the wire rope 101 needs to be less than 1.5°. In order to ensure that the angle α between the starting and ending positions of the wire rope 101 and the wire rope 101 is less than 1.5°, when designing the drum, a certain distance needs to be maintained between the center line of the drum and the pulley 102. In order to avoid spatial interference with the shaking wire rope 101, other mechanisms or equipment cannot be arranged in the space of the spacing, resulting in a waste of overall layout space. In addition, after the first circle of wire rope 101 is arranged, when the remaining circles of wire rope 101 are arranged, due to the lack of rope groove restrictions and the lubricating oil coated on the wire rope 101, the wire rope 101 is easily tangled, derailed or climbed during the process of changing the arrangement angle of the wire rope 101 on the drum through the pulley 102.

[0047] In order to solve the above technical problems, the utility model provides a multi-layer winding drum rope arrangement device.

[0048] A multi-layer winding drum rope arrangement device according to an embodiment of the utility model will first be described in detail below with reference to the accompanying drawings.

[0049] refer to Figure 2 and Figure 3 , Figure 2 This is a top sectional view of a multi-layer winding drum rope arrangement device in an embodiment of the utility model. Figure 3 It is a schematic structural diagram of a multi-layer winding drum rope arrangement device in an embodiment of the utility model.

[0050] like Figure 2 and Figure 3As shown, the multi-layer winding drum rope arrangement device of the embodiment of the utility model is used for the multi-layer winding drum 100, and the multi-layer winding drum 100 is arranged along the first direction. Specifically, the rope arrangement device includes: a joint base 200, a drum driving mechanism 300, a sliding assembly 400, a pulley swing bracket 500, a guide pulley 600 and a sliding driving mechanism 700. Among them, the multi-layer winding drum 100 is rotatably arranged on the joint base 200. The drum driving mechanism 300 is connected to the multi-layer winding drum 100 and is used to drive the multi-layer winding drum 100 to rotate. The sliding assembly 400 is arranged on the joint base 200, and the sliding assembly 400 includes a sliding shaft 410 and a sliding bracket 420 penetrated on the sliding shaft 410, and the sliding shaft 410 is arranged along the first direction. The pulley swing bracket 500 is rotatably connected to the sliding bracket 420, and the direction of the rotation axis of the pulley swing bracket 500 is arranged along the first direction. The guide pulley 600 is connected to the pulley swing bracket 500, and the center line of the guide pulley 600 is arranged along the second direction, the second direction is perpendicular to the first direction, and the guide pulley 600 is used to pull the wire rope 101 to the multi-layer winding drum 100, or to lead the wire rope 101 from the multi-layer winding drum 100. The sliding drive mechanism 700 is connected to the sliding assembly 400, and the sliding drive mechanism 700 is used to drive the sliding bracket 420 to reciprocate along the first direction.

[0051] Specifically, when performing the arrangement operation, the sliding assembly 400 can drive the guide pulley 600 to slide, and the sliding direction and speed of the guide pulley 600 are the same as the arrangement direction and speed of the wire rope 101, so that the extension line c of the wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100 is always perpendicular to the first direction in the horizontal direction. Figure 2 and Figure 3 As shown, since the pulley swing bracket 500 connected to the guide pulley 600 is rotatably connected to the sliding bracket 420, when the wire rope 101 on the guide pulley 600 is pulled, the guide pulley 600 will also turn accordingly, so that the center line b of the guide pulley 600 is parallel to the extension line c of the wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100, thereby avoiding the occurrence of rope tangling, rope falling or rope climbing.

[0052] For example, when performing a winding operation, the multi-layer winding drum 100 can rotate forward to pull the winding wire rope 101, and the wire rope 101 on the multi-layer winding drum 100 is arranged from the first end to the second end. At the same time, the guide pulley 600 also starts to slide from the direction of the first end to the direction of the second end. As a result, the extension line c of the wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100 is always perpendicular to the first direction in the horizontal direction. Then, the guide pulley 600 slides back and forth until the winding operation of the wire rope 101 is completed. During the winding process, since the guide pulley 600 is subjected to the traction force of the multi-layer winding drum 100, the center line b of the guide pulley 600 perpendicular to the first direction is parallel to the extension line c of the wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100. As a result, the occurrence of tangled ropes, rope derailment or rope climbing is avoided.

[0053] In addition, since the steel wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100 is always perpendicular to the first direction in the horizontal direction, the distance between the guide pulley 600 and the multi-layer winding drum 100 can be shortened, saving layout space.

[0054] like Figure 2 As shown, the reel driving mechanism 300 includes: a reel driving motor 310, a high-speed coupling 320 and a reel reducer 330. The reel driving motor 310 is provided with a motor output shaft. The motor output shaft is connected to the input end of the reel reducer 330 through the high-speed coupling 320, and a reel coupling 331 is provided on the reducer output shaft of the reel reducer 330, and the reel coupling 331 is connected to the multi-layer winding reel 100 through a flange.

[0055] In this embodiment, the drum drive motor 310 can output torque through the motor output shaft, and the high-speed coupling 320 is respectively connected to the motor output shaft and the input shaft on the drum reducer 330 to transmit torque, and the reducer output shaft of the drum reducer 330 is provided with a drum coupling 331, which is connected to the multi-layer winding drum 100 through a flange and drives the multi-layer winding drum 100 to rotate. The rolling drive motor has a large output torque, which can match the multi-layer winding drum 100 with a large rope capacity, and improve the winding capacity of the multi-layer winding drum 100.

[0056] In one embodiment of the present invention, the sliding shaft 410 is a screw shaft, the sliding drive mechanism 700 is connected to the screw shaft, and is used to drive the screw shaft to rotate. The sliding bracket 420 is threadedly connected to the screw shaft. As the screw shaft rotates, the sliding bracket 420 reciprocates along the screw shaft. The screw shaft has high stability and high transmission accuracy. Figure 2As shown, by driving the guide pulley 600 connected to the pulley swing bracket 500 to slide through the screw shaft, the extension line c of the wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100 can always be perpendicular to the first direction in the horizontal direction, avoiding the occurrence of rope tangling, rope falling or rope climbing.

[0057] like Figure 2 As shown, the sliding assembly 400 further includes: a guide shaft 430, the guide shaft 430 is inserted into the sliding bracket 420, and both ends of the guide shaft 430 are respectively connected to the joint base 200. In this embodiment, the pulley swing bracket 500 is guided by the guide shaft 430, which can effectively improve the sliding accuracy of the guide pulley 600 connected to the pulley swing bracket 500.

[0058] like Figure 2 As shown, the pulley swing bracket 500 is rotatably connected to the sliding bracket 420 through the swing pin 501, and a limiter is provided on the sliding bracket 420, and the limiter is used to limit the rotation angle of the pulley swing bracket 500. By providing a limiter on the sliding bracket 420 to limit the rotation angle of the pulley swing bracket 500, the wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100 can be prevented from being tangled.

[0059] like Figure 2 As shown, the sliding drive mechanism 700 includes: a sliding drive motor 710 and a sliding reducer 720. Among them, a sliding output shaft is provided on the sliding drive motor 710. The sliding output shaft is connected to the input end of the sliding reducer 720, and the output end of the sliding reducer 720 is connected to the screw shaft. In this embodiment, the sliding drive motor 710 can output torque, and at the same time, the screw shaft can be driven to rotate through the sliding reducer 720. The sliding reducer 720 has high precision and can effectively improve the arrangement precision of the wire rope 101.

[0060] like Figure 2 As shown, the multi-layer winding drum rope arrangement device also includes: a first encoder 800 and a second encoder 900. The first encoder 800 is connected to the multi-layer winding drum 100, and the second encoder 900 is connected to the screw shaft. The first encoder 800 and the second encoder 900 can obtain the rotation rate of the multi-layer winding drum 100 and the sliding shaft 410, and then the construction personnel can adjust the rotation rate of the multi-layer winding drum 100 and the operating rate of the sliding bracket 420 to improve the arrangement accuracy of the wire rope 101.

[0061] In one embodiment of the present invention, a guide groove is provided on the guide pulley 600. The steel wire rope 101 is guided by the guide groove, so that the arrangement accuracy of the steel wire rope 101 can be further improved.

[0062] In summary, the multi-layer winding drum rope arrangement device of the utility model, by setting the sliding assembly 400 to slide the guide pulley 600, makes the extension line c of the steel wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100 always perpendicular to the first direction in the horizontal direction. At the same time, the pulley swing bracket 500 connected to the guide pulley 600 is rotatably connected to the sliding bracket 420, and when the steel wire rope 101 on the guide pulley 600 is pulled, the guide pulley 600 will also turn accordingly, thereby effectively avoiding the occurrence of tangled ropes, rope derailment or rope climbing. In addition, since the steel wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100 is always perpendicular to the first direction in the horizontal direction, that is, the angle between the starting and ending positions of the steel wire rope 101 and the steel wire rope 101 between the guide pulley 600 and the multi-layer winding drum 100 is 0°, the distance between the guide pulley 600 and the multi-layer winding drum 100 can be shortened, saving layout space.
