Description

Technical Field

[0001] The utility model relates to the technical field of lifting, in particular to a two-way rope output device. Background Art

[0002] In lifting operations, the drum is an important mechanical device that can not only realize the transmission and conversion of force, but also play a variety of functions such as support, lifting, and traction. In actual engineering applications, various medium and large-scale engineering hoisting operations require drums to complete. When the lifting operation requires two wire ropes to lift the load at the same time, a double drum structure is usually used. However, when the axial installation space of the drum is limited, a drum with rope grooves at both ends is used instead of a double drum to achieve the simultaneous winding of two wire ropes.

[0003] The existing 2-rope single-layer winding drum and guide pulley are arranged as follows Figure 1 As shown in the figure, the wire rope is wound on the drum, and the inclination angle between the wire rope and the guide pulley 1 or guide pulley 2 is the rope entry angle ɑ (as shown in the figure). Figure 1 The angle of entry (as shown in Figure 1) is within a reasonable range, which is the guarantee for the normal operation of the drum and the premise for the normal service life of the wire rope. If the rope entry angle ɑ is too large, it will cause "rope biting" and aggravate the wear of the wire rope. Therefore, the rope entry angle ɑ should be controlled within the allowable range during design. According to GB / T 3811 "Crane Design Specifications", when the wire rope is wound into or out of the drum, the angle of the wire rope centerline deviating from the spiral groove centerline on both sides should not be greater than 3.5°.

[0004] In order to ensure the requirement of the rope entry angle ɑ, a certain vertical distance H needs to be maintained between the drum and guide pulley 1 or guide pulley 2. In order to avoid spatial interference with the shaking wire rope, other mechanisms or equipment cannot be arranged in the space of the vertical distance H, resulting in a waste of the overall layout space.

[0005] Moreover, in actual use, in order to ensure that the two steel ropes can be pulled out synchronously and the ropes can be arranged smoothly, it is usually necessary to additionally set up a set of motors and rope arrangement mechanisms for rope arrangement, which increases the daily inspection and maintenance work and is labor-consuming and time-consuming.

In addition, in order to synchronize the output of the two wire ropes and arrange the ropes smoothly, an additional set of motors and rope arrangement mechanisms are set up for rope arrangement, which increases the daily inspection and maintenance work, which is labor-consuming and time-consuming.

[0054] The bidirectional rope-discharging device according to the embodiment of the utility model is proposed to solve the problems in the prior art that the space layout is not compact and an additional motor and rope-discharging mechanism need to be provided.

[0055] Figure 2 A schematic diagram showing the arrangement of a two-way rope-discharging device according to an embodiment of the utility model is shown; Figure 3 The schematic diagram of the principle of the bidirectional rope-discharging device of the embodiment of the utility model is shown.

[0056] like Figure 2 As shown, the bidirectional rope discharging device according to the embodiment of the utility model comprises: a drum 1, a driving assembly 2, a transmission assembly 3, a guide assembly 4 and a wire rope. The drum 1 comprises a drum shaft 13 located at the center thereof. The driving assembly 2 is arranged on one side of the drum 1 and connected to one end of the drum shaft 13 to drive the drum 1 to rotate. The transmission assembly 3 is arranged on the other side of the drum 1 and connected to the other end of the drum shaft 13. The guide assembly 4 is arranged parallel to the drum shaft 13 of the drum 1 and connected to the transmission assembly 3 so that the driving assembly 2 sequentially drives the guide assembly 4 to move through the drum 1 and the transmission assembly 3. The wire rope comprises a first wire rope 5 and a second wire rope 6 arranged opposite to each other, one end of the first wire rope 5 is wound around the first section 11 of the drum 1 and the other end passes through the guide assembly 4 and is discharged in a direction parallel to the drum shaft 13, one end of the second wire rope 6 is wound around the second section 12 of the drum 1 and the other end passes through the guide assembly 4 and is discharged in a direction parallel to the drum shaft 13, and the discharge directions of the first wire rope 5 and the second wire rope 6 are opposite.

[0057] Combine the following Figure 2 and Figure 3 The working principle of the two-way rope-discharging device is briefly described. The driving assembly 2 provides power to drive one end of the drum shaft 13 connected thereto to rotate, thereby driving the drum 1 to rotate (e.g. Figure 3 1 and 12), the first section 11 and the second section 12 of the drum 1 are respectively provided with a first steel wire rope 5 and a second steel wire rope 6, one end of the first steel wire rope 5 is wound around the first section 11 of the drum 1, and the other end passes through the guide assembly 4 and is discharged in a direction parallel to the drum axis 13; similarly, one end of the second steel wire rope 6 is wound around the second section 12 of the drum 1, and the other end passes through the guide assembly 4 and is discharged in a direction parallel to the drum axis 13, that is, the discharge angle approaches "0°", and the input angle also approaches "0°", and the discharge directions of the first steel wire rope 5 and the second steel wire rope 6 are opposite, as shown in FIG. Figure 2 That is, reference Figure 2 or Figure 3After the first steel wire rope 5 and the second steel wire rope 6 pass through the guide assembly 4, the movement direction of the guide assembly 4 is the movement direction of the steel wire rope unwinding end on the drum 1 toward the fixed end. In the embodiment of the utility model, by designing such a right-angle rope arrangement method, it is ensured that the rope output angle is always close to "0°". Without adding an additional motor and a rope arrangement device, a transmission assembly 3 is provided. The driving assembly 2 provides power to rotate through the other end of the drum shaft 13 to drive the transmission assembly 3 to rotate. The guide assembly 4 is arranged parallel to the drum shaft 13 of the drum 1 and is connected to the transmission assembly 3 so that the driving assembly 2 drives the guide assembly 4 to move through the drum 1 and the transmission assembly 3 in turn, thereby achieving synchronous right-angle directional rope output of the steel wire rope on the drum 1 and the steel wire rope on the guide assembly 4, such as Figure 2 shown.

[0058] In summary, the bidirectional rope discharging device provided in the embodiment of the utility model is used for winding two ropes in a single layer around a drum, and adopts a right-angle rope arrangement method (i.e., the rope discharging angle approaches 0°), which not only meets the requirement of the drum entry rope angle ɑ≤3.5°, but also does not require the arrangement of a motor and a rope arrangement mechanism to assist the wire rope discharging. The bidirectional rope discharging device improved according to the embodiment of the utility model can ensure that the wire rope is discharged safely and effectively, without rope climbing or tangling, and can also avoid extra space occupation, without affecting the arrangement of other mechanisms or equipment, so that the entire space layout is reasonable and effective, which has important practical significance.

[0059] In some embodiments of the present invention, Figure 2 As shown, the drive assembly 2 includes: a motor 21, a first coupling 22 and a first reducer 23. The motor 21 is arranged on one side of the drum 1 to provide power for the drum 1. One end of the first coupling 22 is connected to the output shaft of the motor 21. The input shaft of the first reducer 23 is connected to the other end of the first coupling 22 and the output shaft is connected to the drum shaft 13 to reduce the output speed of the motor 21 and transmit it to the drum shaft 13. Through this design, the synergistic effect of the motor 21, the first coupling 22 and the first reducer 23 is adopted to effectively convert the power provided by the motor 21 into the appropriate speed and torque required by the drum shaft 13, so that the drum 1 rotates to unwind the first steel wire rope 5 and the second steel wire rope 6.

[0060] In some embodiments of the present invention, Figure 2 As shown, one end of the reel shaft 13 is connected to the output shaft of the first reducer 23 through the second coupling 14, and the second coupling 14 is built into the end of the reel 1.

[0061] That is to say, on the one hand, by setting the second coupling 14 to connect one end of the reel shaft 13 and the output shaft of the first reducer 23, the output speed of the first reducer 23 after being reduced is transmitted to the reel shaft 13. The second coupling 14 is added to increase the relative tolerance when the reel shaft 13 is connected to the output shaft of the first reducer 23 in the device, improves the stability of the device, and ensures the smooth transmission of power. On the other hand, the second coupling 14 is built into the end of the reel 1, which ensures the compactness of the entire device, further avoids the additional occupation of space, does not affect the layout of other mechanisms or equipment, and makes the entire space layout reasonable and effective.

[0062] In some embodiments of the present invention, Figure 2 As shown, the transmission assembly 3 includes a first transmission mechanism 31 and a second transmission mechanism 32. The first transmission mechanism 31 is connected to the other end of the reel shaft 13. The first transmission mechanism 31 includes: a first driving wheel 311, a first driven wheel 312 and a first transmission chain 313. The first driving wheel 311 and the first driven wheel 312 are arranged opposite to each other and are connected through the first transmission chain 313. The first driving wheel 311 is connected to the other end of the reel shaft 13 and the first driven wheel 312 is connected to the second transmission mechanism 32. The second transmission mechanism 32 is connected to the guide assembly 4, so that the reel shaft 13 drives the second transmission mechanism 32 through the first transmission mechanism 31 and then the second transmission mechanism 32 drives the guide assembly 4 to move.

[0063] Specifically, if Figure 2 As shown, according to the bidirectional rope-discharging device of the embodiment of the utility model, the other end of the drum shaft 13 is correspondingly connected to the transmission assembly 3, and the transmission assembly 3 includes a first transmission mechanism 31 directly connected to the other end of the drum shaft 13 and a second transmission mechanism 32 correspondingly connected to the first transmission mechanism 31. Figure 2 The first transmission mechanism 31 on the left side includes a first driving wheel 311 and a first driven wheel 312 which are arranged opposite to each other, and the two are connected by a first transmission chain 313, wherein the first driving wheel 311 is directly connected to the other end of the drum shaft 13, and a bearing seat 15 can be arranged between the first driving wheel 311 and the drum shaft 13 to prevent the drum shaft 13 from loosening or deflecting during rotation, and to disperse the load and strengthen the stability of the device, and the first driven wheel 312 is connected to the second transmission mechanism 32, and the second transmission mechanism 32 is also connected to the guide assembly 4, so that the drum shaft 13 drives the second transmission mechanism 32 through the first transmission mechanism 31, and then the second transmission mechanism 32 drives the guide assembly 4 to move. Therefore, by setting the first transmission mechanism 31 and the second transmission mechanism 32, the power of the drum shaft 13 can be effectively transmitted to the guide assembly 4, so that the guide assembly 4 is driven by the drum shaft 13 to move synchronously, without the need to set up an additional motor and a rope arrangement mechanism, which saves daily inspection and maintenance work and improves work efficiency.

[0064] In some embodiments of the present invention, Figure 2 As shown, the diameter of the first driven wheel 312 is smaller than the diameter of the first driving wheel 311. The first driven wheel 312 and the first driving wheel 311 are connected through the first transmission chain 313 and there is a speed ratio relationship. By setting the diameter of the first driven wheel 312 to be smaller than the diameter of the first driving wheel 311, the first driven wheel 312 can obtain a higher output speed. In other words, by adjusting the diameter between the first driven wheel 312 and the first driving wheel 311, the speed ratio of the first transmission mechanism 31 can be adjusted to meet the speed and torque requirements of different lifting operation application scenarios, further improving the flexibility and adaptability of the device.

[0065] In some embodiments of the present invention, Figure 2 As shown, the second transmission mechanism 32 is arranged below the first driving wheel 311, and the second transmission mechanism 32 comprises: a support plate 321, two supports 322, a second driving wheel 323, a second driven wheel 324, a second transmission chain 325 and a second reducer 326. The support plate 321 is parallel to the reel 1 and is located below the first driving wheel 311; the two supports 322 are respectively arranged at both ends of the support plate 321; the second driving wheel 323 and the second driven wheel 324 are respectively arranged on the supports 322 and are connected by the second transmission chain 325; the input shaft of the second reducer 326 is connected to the first driven wheel 312 and the output shaft is connected to the second driving wheel 323 to reduce the output speed of the first driven wheel 312 and transmit it to the second driving wheel 323, so that the second driving wheel 323 drives the second driven wheel 324 to rotate, and the second transmission chain 325 is connected to the guide assembly 4 to drive the guide assembly 4 to move.

[0066] Specifically, when the first driving wheel 311 rotates, the first driven wheel 312 is driven to rotate through the first transmission chain 313, and then the second transmission mechanism 32 is driven to rotate. The second reducer 326 reduces the output speed of the first driven wheel 312, and drives the rotation of the second driven wheel 324 through the second driving wheel 323. The second transmission chain 325 is connected to the guide assembly 4 to drive the movement of the guide assembly 4. During this period, on the one hand, the transmission ratio (i.e., speed ratio) of the first driving wheel 311 and the second driven wheel 323 is changed by changing the diameter size of the first driving wheel 311 and the second driven wheel 324, and on the other hand, through the action of the second reducer 326 connected to the first driven wheel 312 and the second driving wheel 323, the movement speed of the second transmission chain 325 connected between the second driving wheel 323 and the second driven wheel 324 is matched with the pitch of the first steel wire rope 5 and the second steel wire rope 6 on the drum 1, so that the moving speed of the guide assembly 4 is matched with the unwinding speed of the first steel wire rope 5 and the second steel wire rope 6 on the drum 1 to achieve right-angle rope arrangement.

[0067] In some embodiments of the present invention, Figure 2 As shown, the guide assembly 4 includes two groups of guide mechanisms, each group of guide mechanisms includes a pulley bracket 41 and a guide pulley 42, the guide pulley 42 is arranged on the pulley bracket 41, and the second transmission chain 325 is correspondingly connected to the pulley bracket 41 to drive the guide mechanism to reciprocate along the second transmission chain 325, wherein the other end of the first steel wire rope 5 passes through a guide pulley 42 and the rope entry direction and the rope exit direction of the guide pulley 42 are perpendicular; correspondingly, the other end of the second steel wire rope 6 passes through another guide pulley 42 and the rope entry direction and the rope exit direction of the guide pulley 42 are perpendicular. In the actual arrangement, for example, one of the pulley brackets 41 can be connected to the lower layer of the second transmission chain 325 by a pin, and the other pulley bracket 41 can be connected to the upper layer of the second transmission chain 325 by a pin, so as to ensure that the movement of the second transmission chain 325 drives the two pulley brackets 41 to move synchronously towards each other, that is, drives the two guide mechanisms to move synchronously towards each other. At this time, the rotation directions of the left and right parts of the steel wire rope should be opposite, such as Figure 3 For example, in some other embodiments, not shown, the two pulley brackets 41 can be connected to the upper layer or the lower layer of the second transmission chain 325 by pins at the same time, so as to ensure that the movement of the second transmission chain 325 drives the two pulley brackets 41 to move synchronously in the same direction, that is, drives the two guide mechanisms to move synchronously in the same direction. At this time, the rotation direction of the wire ropes of the left and right parts should be the same.

[0068] In some embodiments of the present invention, Figure 2 As shown, the guide assembly 4 further includes an auxiliary translation module 7 , and the auxiliary translation module 7 includes: a guide rail 71 and traveling wheels 72 .

[0069] The guide rail 71 is disposed on at least one side surface of the support plate 321. The running wheels 72 include at least two pairs, and at least one pair of running wheels 72 is correspondingly disposed on the pulley bracket 41 to assist the pulley bracket 41 to reciprocate on the guide rail 71, and then the second transmission chain 325 drives the guide mechanism to reciprocate. Figure 3 The guide rails 71 shown are respectively arranged on the two side surfaces of the support plate 321, and the four pairs of running wheels 72 are respectively arranged at the two ends of the two pulley brackets 41. The auxiliary translation module 7 provides a smooth moving surface for the guide mechanism through the design of the guide rails 71 and the running wheels 72, ensuring that the guide mechanism can stably reciprocate on the guide rails 71 under the drive of the second transmission chain 325, further improving the stability and safety of the device.

[0070] In some embodiments of the present invention, Figure 2As shown, an anti-interference distance D is defined between the first section 11 and the second section 12 of the drum 1 to prevent the two sets of guide mechanisms from interfering and colliding when they are driven by the second transmission chain 325. The anti-interference distance D is set to ensure that there is enough space between the first section 11 and the second section 12 of the drum 1 to prevent the two sets of guide mechanisms from interfering and colliding with each other during movement, avoid abnormal friction, resistance or damage during the movement of the guide assembly 4, and extend the service life of the device. The length of the anti-interference distance depends on the shortest distance between the rope entry side of the guide pulley 42 in the two sets of guide mechanisms and one end of the pulley bracket 41 close to this side.

[0071] In some embodiments of the present invention, Figure 2 As shown, the first section 11 and the second section 12 of the drum 1 are respectively evenly provided with a plurality of rope grooves 16 for correspondingly winding the first steel wire rope 5 and the second steel wire rope 6. Thus, the first steel wire rope 5 and the second steel wire rope 6 can be fixed and wound in an orderly manner to prevent interweaving and entanglement, further improving the stability of the device.

[0072] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
