Description

Technical Field

[0001] The invention relates to a cable collecting device, in particular to a cable collecting device capable of automatically arranging cables. Background Art

[0002] At present, when collecting cables, the take-up reel or drum usually reels the cables at a certain position, resulting in messy and uneven cable winding. In particular, for application conditions that rely on the speed of the variable frequency motor and the outer diameter of the reel to determine the cable collection length, when the cable is unevenly wound, the motor cannot determine the take-up length when it rotates a certain number of times. Manual assistance is required to move the winding position so that the cables are arranged neatly. This method not only increases labor costs, but the cable arrangement uniformity does not meet the requirements of working conditions with high winding accuracy requirements.

[0003] Therefore, cable arranging devices are increasingly used for cable collection. At present, the more commonly used cable collection devices with cable arranging functions generally include a winding mechanism and a cable arranging mechanism, and are controlled by corresponding motors. Such devices are not only large in size and complex in structure, but also require a connection between the two motors to work together. There may also be a situation where the cable arranging wheel and the winding position are inconsistent. At this time, the motor needs to be readjusted, which seriously affects the reliability of the equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a cable collection device that can automatically arrange cables, which adopts a winch to directly drive the reel and the threaded transmission rod, and drives the cable arrangement wheel to move linearly through threaded transmission to achieve precise cable arrangement, and the cable arrangement problem of cables coming from any direction can be achieved by changing the shape of the sliding bracket.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a cable collection device capable of automatically arranging cables, comprising a rotating drive mechanism and a reel, the rotating drive mechanism drives the reel to rotate to collect cables, and also includes a cable arranging wheel arranged on the side of the reel where the cables enter, the cable arranging wheel moves in a straight line in a direction parallel to the rotation axis of the reel under the drive of the sliding component, and guides the cables to be entered into the reel for arranging during the movement, so that the cables are evenly wound on the reel; the sliding component is arranged on a sliding guide rail and moves along the sliding guide rail, the sliding component is connected by a connecting rod and a threaded slider, both ends of the connecting rod and the sliding component and the threaded slider are fixedly connected, the threaded slider is screwed on the threaded transmission rod by a thread, the threaded transmission rod is fixed to the end face center of the reel, and can rotate synchronously with the reel.

[0006] A limiting nut is also provided at the end of the threaded transmission rod.

[0007] The sliding assembly comprises a sliding bracket and a pulley installed at one end of the sliding bracket, and the other end of the sliding bracket is used to install the wire arrangement wheel, and the wire arrangement wheel is installed on the sliding bracket in a freely rotating manner.

[0008] The pulley is arranged in the sliding guide rail, and the inner wall of the sliding guide rail provides support for the pulley.

[0009] The sliding bracket is provided with double-row pulleys.

[0010] The pulley is mounted on the sliding bracket through a bearing.

[0011] A guide wheel is also provided in the direction of the incoming wire of the wire arrangement wheel, and the wire is wound on the reel after passing through the guide wheel and the wire arrangement wheel.

[0012] The sliding bracket has different specifications, so that the center of the wheel groove of the installed cable arranging wheel matches the direction of the cable, so as to prevent the cable from twisting when passing through the cable arranging wheel, and enable the cable arranging wheel to push the cable to be arranged on the reel during the cable arranging process.

[0013] The "center of the groove of the cable arranging wheel matches the direction of the cable" means that when a guide wheel is provided, the plane where the center of the groove of the cable arranging wheel is located is parallel to the plane where the center of the groove of the guide wheel is located, so that the cable can smoothly enter the groove of the cable arranging wheel after passing through the guide wheel; or, when no guide wheel is provided, the plane where the center of the groove of the cable arranging wheel is located is parallel to the cable, and the cable can enter the groove of the cable arranging wheel, so that the cable arranging wheel can arrange the cable later. The groove has a V-shaped cross section, and its lowest point forms a closed loop, which is the center of the groove, and the plane where the loop is located is the plane where the center of the groove is located mentioned above.

[0014] The pitch of the thread on the threaded drive rod is equal to the diameter of the cable.

[0015] The rotary drive mechanism adopts a winch, and the output shaft of the winch is connected to the drum through a key.

[0016] The present invention has the following innovations and advantages: 1. The present invention drives the reel to wind up the cable through a winch, and the rotation of the reel simultaneously drives the threaded transmission rod to rotate synchronously with the same angular velocity. During the rotation of the threaded transmission rod, the threaded slider matched therewith moves in a straight line in one direction through threaded transmission. Because the cable arranging wheel is installed on the sliding assembly, and the sliding assembly and the threaded slider are connected by a connecting rod, the movement of the threaded slider will drive the sliding assembly and the cable arranging wheel to move in a straight line at the same speed and direction, so that the cable arranging wheel can push the cable to move in the winding position on the reel, thereby completing the cable arranging on the reel. This device is used for single-layer winding of the cable on the reel, so the cable arranging wheel only needs to move in one direction.

[0017] 2. Due to the threaded transmission relationship between the threaded slider and the threaded transmission rod, the pitch of the thread on the threaded transmission rod and the threaded slider defines the moving distance of the threaded slider after the drum rotates one circle, which directly affects the density of the cable winding on the drum. Therefore, the pitch of the threaded transmission rod and the threaded slider can be adjusted, such as replacing the threaded transmission rod and the threaded slider with different pitches to obtain higher cable arrangement accuracy. In the present invention, the pitch is set to be consistent with the cable diameter, so that when the cable is wound around the drum once, the cable arrangement wheel just moves a distance of the cable diameter, and the cable is finally arranged more densely on the drum.

[0018] 3. The present invention can select sliding brackets of different specifications according to the direction of the incoming line. "Sliding brackets of different specifications" means that after the cable arranging wheel is installed, the sliding bracket is installed in the sliding guide rail. At this time, the shape of the sliding bracket can make the center plane of the wheel groove of the cable arranging wheel and the center plane of the wheel groove of the guide wheel parallel, which is convenient for the cable arranging wheel to push the cable on the reel to arrange the cable, thereby achieving the purpose of arranging cables with different incoming directions; the center plane of the wheel groove refers to the circumferential surface formed at the bottom of the wheel groove.

[0019] 4. The cable arranging wheel in the present invention is installed on a sliding bracket, and the pulley on the sliding bracket can obtain a large supporting force from the inner wall of the sliding guide rail, so that the cable arranging wheel can withstand a certain cable pressure and is suitable for occasions where linear flexible bodies such as cables and wire ropes need to withstand strong tensile forces.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the invention in any way.

[0026] This embodiment is an accessory component for fuel transportation equipment. The fuel transportation equipment has extremely high operating accuracy requirements. Its tipping mechanism uses a winch to drive a steel wire rope to flip the fuel basket. The movement length of the steel wire rope is determined by the rotation angle of the winch, and then the tipping angle of the fuel basket is determined to achieve precise position control. At present, the device relies on the extrusion of the steel wire rope for cable arrangement. The friction between the steel wire ropes is large, and the steel wire ropes wear quickly. The use of the cable collection device described in the present invention can effectively solve the problems of automatic cable arrangement and winding wear of the equipment's steel wire ropes, and improve the operating stability and safety reliability of related equipment.

[0027] The cable collection device capable of automatically arranging the wires of the present invention is an auxiliary component of the above-mentioned fuel transportation equipment, and is used to assist the drum in neatly and orderly arranging the wire ropes when the drum is winding the wire ropes. The device includes a winch, a drum, a guide wheel and a wire arrangement wheel. The connection mode and working process of its structure are described in detail below. The following descriptions of the directions, such as "above", "below", "inside", "outside", "clockwise", "counterclockwise", etc., are all based on the directions shown in the drawings of the specification, and are not limitations on the technical solution of the present invention.

[0028] The winch 1 is connected to the drum 2 by a key, driving the drum 2 to rotate to wind the wire rope 10 to achieve winding or unwinding, and the threaded transmission rod 3 is fixed to the center position of the end surface of the drum 2 by a screw. When the drum 2 rotates, the threaded transmission rod 3 rotates with the drum 2 at the same angular velocity; the threaded slider 4 and the threaded transmission rod 3 are screwed together by threads, and when the threaded transmission rod 3 rotates, the threaded slider 4 moves linearly along the threaded transmission rod 3 through thread transmission; one end of the connecting rod 5 is fixed to the threaded slider 4, and the other end is fixedly connected to the sliding assembly 6, and the sliding assembly 6 is slidably set on the sliding guide rail 7, and the wire arranging wheel 8 is installed on the sliding assembly 6. Through the connecting rod 5 and the sliding assembly 6, the wire arranging wheel 8 and the threaded slider 4 can move linearly synchronously, and the moving speed and moving distance are the same; the sliding assembly 6 includes a sliding bracket 11 and two rows of four pulleys 12, and the pulleys 12 are all rotated through bearings It is arranged at one end of the sliding bracket 11, and the wire arranging wheel 8 is also installed at the other end of the sliding bracket 11 through a bearing, and is fixed and constrained by a nut on the outside of the bearing to prevent the wire arranging wheel 8 from falling off; one end of the sliding guide rail 7 is fixed to the frame by bolts, and the other end is an opening for the pulley 12 in the sliding assembly 6 to enter and exit the sliding guide rail 7. The width of the slot on the side of the sliding guide rail 7 is slightly larger than the thickness at the corresponding position of the sliding bracket 11. The pulley 12 on the sliding bracket 11 is in the sliding guide rail 7, and the rest of the part extends out from the slot on the side of the sliding guide rail 7. When the sliding assembly 6 realizes linear movement through the rolling of the pulley 12 in the sliding guide rail 7, the inner wall of the sliding guide rail 7 can provide supporting force for the pulley 12. According to the distance from the slot on the side of the sliding guide rail 7, the two opposite inner walls of the sliding guide rail 7 can be divided into a distal inner wall 701 and a proximal inner wall 702, which provide supporting force for the pulley 12 under different working conditions.

[0029] The guide wheel 9 is arranged in the direction of the wire rope 10, and can tension and guide the wire rope 10 to enter the drum 2. The wire arranging wheel 8 is located between the guide wheel 9 and the drum 2. The wheel groove of the wire arranging wheel 8 is in contact with the wire rope 10. During the winding process, the wire rope 10 causes the wire arranging wheel 8 to rotate through friction.

[0030] Furthermore, the pitch of the threaded transmission rod 3 and the threaded slider 4 is consistent with the diameter of the wire rope 10, that is, when the drum 2 rotates one circle, the wire arrangement wheel 8 moves a distance of the wire rope diameter, so that the wire rope 10 is evenly and tightly arranged on the drum 2.

[0031] When in use, one end of the steel wire rope 10 is connected to the fuel basket, and the other end is connected to the drum 2 through the guide wheel 9 and the wire arrangement wheel 8. When winding is required, the winch 1 drives the drum 2 and the threaded transmission rod 3 to rotate counterclockwise, and the drum 2 winds and reels the steel wire rope 10. The threaded transmission rod 3 and the threaded slider 4 move relative to each other, so that the threaded slider 4 moves inward (close to the drum) along the axial direction of the threaded transmission rod 3. Due to the connection of the connecting rod 5, the threaded slider 4 drives the sliding assembly 6 and the wire arrangement wheel 8 to move at the same speed and direction, and the wire arrangement wheel 8 pushes the steel wire rope 10 to be arranged on the drum 2 circle by circle; in this process, the threaded transmission rod 3 also generates a reverse rotation (counterclockwise) force on the threaded slider 4, which is transmitted by the connecting rod 5, so that the pulley 12 in the sliding assembly 6 contacts the proximal inner wall 702 of the sliding guide rail 7, and leaves a small gap with the distal inner wall 701, and the proximal inner wall 702 provides a stable supporting force for the pulley 12.

[0032] On the contrary, when it is necessary to release the wire, the winch 1 drives the drum 2 and the threaded transmission rod 3 to rotate clockwise, and the threaded slider 4 moves axially outward along the threaded transmission rod 3, driving the sliding assembly 6 and the wire arranging wheel 8 to move at the same speed and direction. During the release of the wire, the wire rope 10 is always pressed on the wheel groove of the wire arranging wheel 8, thereby maintaining a certain degree of tension. At the same time, the threaded transmission rod 3 generates a positive rotation (clockwise) force on the threaded slider 4, so that the pulley 12 of the sliding assembly 6 and the distal inner wall 701 of the sliding guide rail 7 are in contact, and the distal inner wall 701 provides a stable supporting force for the pulley 12.

[0033] In order to prevent the threaded slider 4 from disengaging from the threaded transmission rod 3 during the line-releasing process, a limit nut is installed at the outer end of the threaded transmission rod 3 for limiting the position, and the length of the threaded transmission rod 3 is less than or equal to the length of the sliding guide rail 7 to prevent the pulley 12 from disengaging from the sliding guide rail 7 from the opening at the end of the sliding guide rail 7.

[0034] It should be noted that the shapes and installation positions of the transmission threaded rod 3, threaded slider 4, connecting rod 5, sliding assembly 6, sliding guide rail 7, etc. described in the above specific embodiments can be appropriately changed according to the needs of the installation environment. As long as they do not violate the ideas of the present invention, they should also be regarded as the contents disclosed by the present invention.

[0035] When the specifications of the sliding components are different, the cable wheel will also present different installation states, such as Figure 4 (a), (b) and (c) show different states of the cable arranging wheel.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Those skilled in the art should understand that the specific implementation modes of the present invention may be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
