A spooling device for a pasture cable

Abstract

This utility model relates to a rewinding device for ranch ground cables, belonging to the technical field of rewinding equipment. It includes a wire feeding frame with a wire feeding reel and a wire winding frame with winding heads. Two sets of winding heads are installed on the wire winding frame, which alternately wind, bind, and remove the ground cable. A buffer wheel and a braking device are installed on the wire feeding frame. The buffer wheel is movably mounted on the top of the wire feeding frame via a swing arm and is secured with a spring rope. When the winding heads rewind the ground cable under the drive of a reduction motor, the tension generated at the beginning of the ground cable causes the buffer wheel to swing, pulling the brake disc away from the wire feeding reel via a transmission rod. As the braking resistance decreases, the wire feeding reel releases the ground cable. The buffer wheel dynamically adjusts the ground cable tension throughout the rewinding process. After the ground cable is led out from the wire feeding reel, it sequentially passes around the guide wheel and the buffer wheel, is measured in length by a meter counter, is wound by the wire winding wheel, and finally wound onto the winding heads. The combination of these multiple structures forms a complete path for ground cable rewinding.

Description

Technical Field

[0001] This utility model relates to the technical field of rewinding equipment, and in particular to a rewinding device for ranch ground cables. Background Technology

[0002] Ground cables are mainly used for power supply and communication. To facilitate transportation, they are usually wound onto large-diameter reels after production. In the construction and maintenance of infrastructure such as power supply and equipment communication in ranches, they need to be split into rolls according to actual usage requirements, cutting the rolls of ground cables into specific lengths and winding them neatly.

[0003] Existing ground cable rewinding methods mostly rely on manual assistance and mechanical structures, lacking structures for adjusting and protecting the ground cable tension. Especially when the motor drives the winding head to rewind and lead out the ground cable, the unwinding speed and winding speed are mismatched. The ground cable head is subjected to excessive instantaneous tension, causing tensile deformation or damage to the outer sheath. This is particularly noticeable to the flexible PVC insulated ground cables commonly used in ranches. On the other hand, after winding, the machine needs to be stopped to tie the ground cable, remove the rewound ground cable spool, and re-fix the winding. The disassembly and assembly steps are cumbersome and time-consuming, resulting in low rewinding efficiency. Utility Model Content

[0004] In order to improve the problems in the unwinding process of ground cables in the above-mentioned background art, this utility model provides a unwinding device for pasture ground cables.

[0005] The present invention provides a rewinding device for ranch cables, which adopts the following technical solution: A rewinding device for ranch ground cables includes a wire feeding frame with a wire feeding reel and a wire laying frame with a winding head; the wire feeding frame is equipped with a swing arm, one end of which is movably mounted on the top of the wire feeding frame via a hinge shaft, and the other end is tied to the wire feeding frame via a spring rope. A buffer wheel is rotatably provided at one end of the swing arm connected to the spring rope, and the swing arm swings flexibly around the hinge shaft to buffer the instantaneous tension on the ground cable and prevent the insulation sheath of the ground cable from tearing or being stretched and deformed. One end of the hinge shaft extends to the side of the wire feeding frame and is connected to a braking device that brakes the wire feeding reel.

[0006] The braking device includes multiple hinged transmission rods. A brake disc is connected to the end of each transmission rod away from the hinge axis. The rotation of the hinge axis is converted into linear displacement of the brake disc. The brake disc abuts against a rolling wheel connected to the central shaft of the wire feeding reel.

[0007] Furthermore, the cable tray is fixedly equipped with a winding wheel for leading out the ground cable from the cable reel on the side facing the cable feeding tray, thereby optimizing the winding path by adding a winding wheel.

[0008] The cable tray is also equipped with a meter counter and a cable tray between the cable guide wheel and the winding head, so as to realize the accurate measurement and orderly arrangement of the ground cable rolls.

[0009] Furthermore, the winding head includes a rotating core connected to the output end of the geared motor, and the top of the cable tray is equipped with a control console. The control module inside the control console is electrically connected to the geared motor. An inner disc is fitted on the rotating core, and an outer disc is threaded to the outer end of the rotating core. During disassembly and assembly, only the outer disc needs to be turned to remove the reel.

[0010] The outer disc includes a rotating shaft, and a leaf plate corresponding to the inner disc is arranged around the rotating shaft. A binding groove is opened on the rotating core corresponding to the gap between adjacent leaf plates. The binding strap can be directly passed through the binding groove to bind the ground cable roll, which greatly shortens the binding time.

[0011] Furthermore, the cable tray is equipped with two sets of winding heads to enable continuous winding operations and significantly shorten the overall operation time.

[0012] In summary, this utility model has the following beneficial technical effects: 1. After the ground cable is led out from the pay-off reel, it passes through the guide wheel and buffer wheel in sequence. After the length is measured by the meter counter, the cable is laid out by the cable laying wheel and finally wound on the winding head. The combination of multiple structures forms a complete path for ground cable rewinding, which improves the efficiency of ground cable rewinding and has practicality and promotion value.

[0013] 2. This utility model installs a buffer wheel and a braking device on the pay-off frame. The buffer wheel is movably mounted on the top of the pay-off frame via a swing arm and is tied with a spring rope. When the winding head is driven by the reduction motor to spool the ground cable, the tension generated at the beginning of the ground cable will cause the buffer wheel to swing towards the winding head. This prevents the beginning of the ground cable from being stretched or damaged due to excessive instantaneous tension when the pay-off speed and the winding speed are mismatched. At the same time, when the buffer wheel rotates, it pulls the brake disc away from the pay-off reel through the transmission rod. As the braking resistance decreases, the pay-off reel releases the ground cable. The buffer wheel dynamically adjusts the tension of the ground cable throughout the spooling process to prevent stretching or loosening during the winding head winding.

[0014] 3. This utility model has two sets of winding heads on the cable tray, and the winding heads are designed with an inner and outer disc structure that is easy to disassemble. The two sets of winding heads alternately wind, bind and pick up the ground cable, without stopping the machine, thus improving work efficiency. Attached Figure Description

[0017] The following combination Figures 1-3 The present invention will be described in further detail below.

[0018] This utility model discloses a rewinding device for ranch ground cables.

[0019] Reference Figure 1 A reeling device for ranch ground cables includes a cable feeding frame 1 with a cable feeding reel 11. The cable feeding frame 1 is equipped with a swing arm 12. One end of the swing arm 12 is movably mounted on the top of the cable feeding frame 1 via a hinge shaft 121, and the other end is tied to the cable feeding frame 1 via a spring rope 122. A buffer wheel 13 is rotatably provided at one end of the swing arm 12 connected to the spring rope 122. One end of the hinge shaft 121 extends to the side of the cable feeding frame 1 and is connected to a brake device 14 that brakes the cable feeding reel 11.

[0020] Furthermore, the braking device 14 includes multiple hinged transmission rods 141, each including an active rocker arm and a driven rocker arm. One end of the active rocker arm is connected to an extension of the hinge shaft 121, and the other end is hinged to one end of the driven rocker arm. The other end of the driven rocker arm is connected to a brake disc 142. That is, the end of the transmission rod 141 away from the hinge shaft 121 is connected to the brake disc 142, and the brake disc 142 abuts against a rolling wheel 143 connected to the central shaft of the wire reel 11. When the change in local cable tension causes the buffer wheel 13 to swing, the hinge shaft 121 rotates, causing the main rocker arm to move up and down. This causes the end of the rocker arm closer to the main rocker arm to swing downwards, and the end of the rocker arm farther from the main rocker arm to swing upwards, so that the brake disc 142 moves away from the rolling wheel 143, thus releasing the restriction on the pay-off reel 11.

[0021] Reference Figure 1 A reeling device for ranch ground cable also includes a cable tray 2 with a winding head 21; a winding wheel 22 for leading out the ground cable on the cable reel 11 is fixedly installed on the side of the cable tray 2 facing the cable release frame 1; a meter counter 24 and a cable tray 25 are also installed on the cable tray 2 between the winding wheel 22 and the winding head 21.

[0022] The meter counter 24 includes a meter counting wheel and a pressure wheel located above the meter counting wheel. The meter counting wheel shaft is externally connected to a gear and equipped with a speed sensor. The pressure wheel cooperates with the meter counting wheel to clamp the ground cable. The downward pressure of the pressure wheel can be achieved by the compression of the spring on the upper side of the pressure wheel. The cable guide wheel 25 is mounted on a screw. The screw is driven to rotate by a motor. The motor alternately rotates forward and backward to realize the reciprocating movement of the cable guide wheel.

[0023] Furthermore, combined Figure 2 , Figure 3 The winding head 21 includes a rotating core 221, which is connected to the output end of the geared motor. The top of the cable tray 2 is equipped with a control console 23, and the geared motor is electrically connected to the control module inside the control console 23. An inner disc 222 is fitted on the rotating core 221, and an outer disc 223 is threaded to the outer end of the rotating core 221. The outer disc 223 includes a rotating shaft 2231, and a leaf plate 2232 corresponding to the inner disc 222 is provided around the rotating shaft 2231. A binding groove 2211 is opened on the rotating core 221 corresponding to the gap between adjacent leaf plates 2232.

[0024] As an optional structure, a permanent magnet is embedded in the inner circumferential surface of the outer end of the rotating core 221, and the rotating shaft 2231 of the outer disk 223 is magnetically attracted to the rotating core 221, so as to realize the detachable connection between the rotating core 221 and the outer disk 223.

[0025] Furthermore, the cable tray 2 is equipped with two sets of winding heads 21, which alternately wind, bind, and remove the ground cable.

[0026] The implementation principle of the rewinding device for ranch ground cables in this embodiment of the present invention is as follows: The ground cable is led out from the cable reel 11, passes around the winding wheel 22 and buffer wheel 13 in sequence according to the cable routing order, is measured by the meter counter 24, and is wound onto the winding head 21 after being routed by the cable laying wheel 25.

[0027] When the length of the ground cable detected by the meter counter 24 reaches the preset value, the control module inside the console 23 issues a warning. The operator cuts the ground cable and inserts the cut end of the ground cable into another winding head 21 for rewinding. The ground cable on the fully wound winding head 21 is then tied and removed.

[0028] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
