Detailed Description
The utility model will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.
As shown in fig. 1 to 3, the reel for automatically winding and unwinding cables provided in this embodiment includes a support frame 1, a spool 2, a driving member 3, a damper 4, a rotational travel limiter 5, a wire arranging device 6, a bearing housing 7, and a second chain 8.
The support frame 1 is a frame body structure and provides a support and installation structure of the whole reel, and the support frame 1 is installed in complete equipment needing to carry the reel.
The two ends of the winding drum 2 are extended with rotating shafts 21, and the rotating shafts 21 are rotatably arranged at the upper end of the supporting frame 1 through bearing seats 7. The rotating shaft 21 at one end of the winding drum 2 is provided with a first driven wheel 22, and the rotating shaft 21 at the other end is provided with a second driven wheel 23.
The driving member 3 includes a gear motor 31, a driving sprocket 32, and a first chain 33. The gear motor 31 is horizontally arranged at the lower end of the support frame 1, and a driving chain wheel 32 is arranged on a motor shaft of the gear motor. And a damper 4 and a swing stroke limiter 5 are provided in this order on the extended end of the motor shaft. The damper 4 is a magnetic damper.
The drive sprocket 32 is connected to the first driven wheel 22 by a first chain 33.
The winding device 6 is vertically arranged beside the winding drum 2 and comprises a screw rod 61, a guide rod 62 and a winding device 63. The screw rod 61 is rotatably installed on the support frame 1 through the bearing seat 7, and the screw rod 61 is positioned in the middle. The screw rod 61 is provided with a front screw thread and a back screw thread. The guide rod 62 is connected with the support frame 1 at the upper and lower ends of the screw rod 61. One end of the screw 61 is provided with a third driven wheel 611 corresponding to the second driven wheel 23, and the second chain 8 is connected with the second driven wheel 23 and the third driven wheel 611.
The wire feeder 63 includes a connection plate 631, a first bearing 632, a ball device 633, a second bearing 634, and a wire feeder 635. The two ends of the connecting plate 631 are respectively provided with a first bearing 632 which is matched with the two guide rods 62. The first bearing 632 is a linear bearing. A ball device 633 is provided in the middle of the connection plate 631. The ball device 633 is internally provided with balls which are slidably fitted in screw grooves formed in the screw 61. Along with the rotation of the screw 61, the balls are driven to slide in the thread grooves, so that the displacement of the wire arranging device 63 on the screw 61 is realized. Since the screw 61 is provided with the positive and negative screw threads, the traverse displacement of the traverse 63 on the screw 61 can be realized.
The connecting plate 631 is provided with a wire outlet 635, and the wire outlet 635 is located between the ball device 633 and the first bearing 632 disposed below. The second bearings 634 are disposed on the side of the winding displacement opening 635 near the winding drum 2 and the side away from the winding drum 2. The second bearing 634 is a nylon rolling bearing. The second bearing 634 surrounds the wire outlet 635. And the second bearing 634 is disposed at a front-rear interval from the wire arrangement port 635. When the cable passes through the cable outlet 635, the plurality of second bearings 634 are in rolling contact with the cable, so that the friction force between the cable and the cable outlet 635 is greatly reduced, and the cable is prevented from being damaged due to overlarge friction force. By combining the two first bearings 632, the wire arranging device 63 is effectively prevented from being shifted up and down in the process of moving left and right, and the clamping stagnation of the wire arranging device 63 is avoided.
The driving structure of the reel for automatically winding and unwinding cables is as follows: the speed reducing motor 31 for selecting the servo drives the winding drum 2 to roll through the first chain 33, and the drum of the winding drum 2 drives the screw rod 61 to rotate through the second chain 8, so that the wire arranging device 63 is driven to move on the screw rod 61, and the synchronism of all actions is improved. The cable is wound on the winding drum 2, and the cable passes through the cable outlet 635 and is connected with other devices.
The damper 4 may provide the required resistance torque to the gear motor 31 according to actual needs, and the swing stroke limiter 5 may limit the rotation of the gear motor 31.
The rotation travel limiter 5 can effectively limit the rotation of the gear motor 31, and when the cable on the winding drum 2 is pulled out to a set length or recovered to the set length, the rotation travel limiter 5 can limit the rotation of the gear motor 31, so that the cable is prevented from being damaged due to pulling.
When the cable is released, if the winding drum 2 rotates too fast, the cable on the winding drum 2 can loose and climb the ring; if the drum 2 rotates too slowly, the cable is easily broken. The damper 4 is designed to provide a certain rotational reaction torque to the gear motor 31 in view of the above-described problem. For example, when the cable needs to be pulled out, the anti-torque force can be designated for the gear motor 31, and when the pulling force is greater than the anti-torque force, the gear motor 31 is started to drive the winding drum 2 to rotate, so that the cable is paid out.
For protecting the driving parts, protective covers are arranged on the chain wheels and the chains, and fig. 2 and 3 are schematic diagrams with the protective covers removed.
When the reel is mounted on the self-walking equipment, the speed of pulling out the cable is synchronous with the moving speed of the movable equipment, and the anti-torque value is set for the gear motor 31 through the damper 4, so that the synchronization of the cable pulling-out speed and the moving speed of the self-walking equipment can be realized only by the tension provided by the self-walking equipment being larger than the anti-torque force provided by the damper 4, and the phenomenon that the cable is easy to be broken and damaged can be effectively avoided. The magnitude of the reactive torque provided by the damper 4 can be adjusted at any time according to actual needs, and the damper is suitable for cables of all specifications.
The automatic cable winding and unwinding reel can realize the mutual matching between the rotation speed of the winding drum 2 and the moving speed of the cable arranging device 63, so that the cable is wound on the winding drum 2 and translated to one side, and the cable is wound on the winding drum 2 in a threaded rotation mode. The front and back threads on the screw rod 61 further realize bidirectional (front and back) translation of the wire arranging device 63, when the winding drum 2 completes one-layer cable recovery, the wire arranging device 63 can reversely move to start second-layer cable recovery, and thus, the repeated recovery of the cables in a layered and orderly manner can be realized, and the phenomenon of cable recovery disorder is avoided.
When the reel for automatically winding and unwinding the cable is arranged on the self-walking equipment, the controller of the self-walking equipment can send a corresponding voltage signal to the reel controller according to the walking speed of the self-walking equipment, and the reel controller receives the voltage signal and then controls the speed of the speed reducing motor 31 so as to control the speed of the cable recovery. Therefore, the speed of the reel for recovering the cable is synchronous with the running speed of the self-walking equipment, and the automatic cable winding and unwinding of the reel is realized.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
