Description

Technical Field

[0001] This utility model relates to the field of cable winding, and specifically to a cable coiling device. Background Technology

[0002] In the upgrading and renovation of old subway stations, tasks such as channel steel installation, grounding copper busbar installation, cable crimping, and distribution cabinet transportation are frequently encountered. The low-voltage cable involved in the cable crimping operation weighs approximately 6.2 tons and is 520 meters long. It needs to be installed under the station platform to connect two sets of low-voltage switchgear in the low-voltage distribution rooms at both ends of the station. The cable length between the two sets of switchgear is at most 260 meters, requiring half a reel of low-voltage cable. Because it is an old subway station, if the entire reel of low-voltage cable is transported to the site and then cut, the platform cannot meet the load-bearing requirements; that is, the platform cannot withstand a 6.2-ton load. Furthermore, the height of many transport passages in old subway stations is insufficient, with some locations only about 2 meters high, making it impossible to transport the entire reel of low-voltage cable. Therefore, it is necessary to cut the 520-meter reel of low-voltage cable into 260-meter sections at the material warehouse before transporting it to the work site. However, existing coiling devices are unsuitable in size, too tall, or unable to coil half a reel of low-voltage cable. They are also immobile, making the transfer of half a reel of low-voltage cable cumbersome. For example, Chinese invention patent application CN118954200A discloses a cable winding device including a support frame with a cable tensioning assembly. A main gear is fixedly mounted through the axis of the winding reel, extending from the support frame. A tensioning gear is rotatably mounted on one side of the support frame, and a spiral spring is installed inside the tensioning gear. A drive rod is fixedly mounted at one end of the spiral spring. Two sets of compression guide rollers are mounted on the support frame, which are used to compress the cable and rotate synchronously with the cable's movement. The spiral spring drives the compression guide rollers to rotate and tighten the cable. The aforementioned patent application for cable winding and tightening is unsuitable for use in old subway stations due to its weight and size, and it is also inconvenient to move. For example, Chinese invention patent application CN119079697A discloses a cable winding machine and its winding method, including a mounting box, a variable diameter winding assembly, a drive unit, and a limiting unit. The limiting unit is used to restrict the cable being wound onto the variable diameter winding assembly. A lead wire unit, located on the mounting box, guides the cable to wind evenly onto the variable diameter winding assembly. A support unit, located on one side of the mounting box, supports the variable diameter winding assembly. A transfer unit, located on the support unit, transfers the wound cable from the variable diameter winding assembly. In use, this device controls the movement of two sleeves by controlling the rotation of the rotating shaft. Then, the side plate drives the support plate to rotate, increasing or decreasing the distance between the horizontal shaft and the rotating shaft to facilitate winding cables of different diameters. It is convenient to use. However, the aforementioned patent application, designed for easy packaging and bundling of the cable rolls, is bulky and unsuitable for use in old subway stations, and is also inconvenient to move.

[0003] In view of this, the present invention provides a cable reeling device, which realizes the function of cable reeling by setting up a power unit, a transmission unit and a reel unit, and adapts the height of the reel frame and trapezoidal screw to the height of the transport passage of old subway stations by designing the height of the reel frame and trapezoidal screw, and facilitates the transfer of half reel of low voltage cable by setting up a frame body and universal casters.

[0010] Preferably, the moving clutch is provided with a groove, and the shift fork is provided with a lever that cooperates with the groove.

[0015] This invention utilizes a power unit, a transmission unit, and a cable reel unit to achieve cable coiling operations.

Detailed Implementation

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1:

[0022] Reference Figures 1 to 3 As shown, a cable reeling device includes a frame unit 1, a power unit 2, and a cable reel unit 4. The improvement lies in that: the power unit 2 and the cable reel unit 4 are mounted on the frame unit 1; the power unit 2 drives the cable reel unit 4 to rotate via a transmission unit 3 to achieve cable reeling; the frame unit 1 includes a frame body 11, universal casters 12 located at the corners of the frame body 11, and a trapezoidal screw 13; the cable reel unit 4 includes a rotating shaft 41 mounted on the frame body 11, a rotating drum 43 mounted on the rotating shaft 41 and rotating with the rotating shaft 41, and a cable reel outer frame 44; the sum of the diameter of the cable reel outer frame 44 and the height of the trapezoidal screw 13 does not exceed 1.9m; ​​the power unit 2 drives the rotating shaft 41 to rotate via the transmission unit 3 so that the cable is reeled onto the rotating drum 43.

[0023] In this embodiment, the frame unit 1 serves as the support and movement mechanism for the entire coiling device. The frame unit 1 supports the power unit 2, transmission unit 3, and cable reel unit 4. After the cable is coiled, the universal casters 12 transport the cable to a predetermined position. The universal casters 12 facilitate the transport of the coiled cable. The trapezoidal screw 13 adjusts the height of the entire coiling device. When the universal casters 12 are off the ground, they provide fixation and support for the entire coiling device. The power unit 2 provides power for the cable coiling and, through the transmission unit 3, drives the cable reel unit 4 to rotate, completing the cable coiling operation. The rotating drum 43 is used to coil the cable, and the outer frame 44 of the cable reel is used to organize the coiled cable.

[0024] This embodiment achieves cable coiling operations by setting up a power unit, a transmission unit, and a cable reel unit. By designing the diameter of the cable reel's outer frame and the height of the trapezoidal lead screw, the overall height of the coiling device is limited to meet the 2-meter height limit requirement during the renovation of old subway stations. Simultaneously, since the entire coiling device only coils 260m of cable, its total weight is approximately 3 tons, which also meets the load-bearing limit requirements of old subway station passageways. The frame body and swivel casters facilitate the transfer of the entire coiling device after coiling, making it easy to conveniently and smoothly transport half a reel of cable to the designated location. Compared with existing technologies, this embodiment can conveniently realize cable coiling operations and is adaptable to the operational requirements of old subway station renovation and upgrades.

[0025] Furthermore, refer to Figure 1 , 2 As shown, the power unit 2 includes a motor 21 and a reducer 22 connected to each other. The output shaft of the reducer 22 is connected to the transmission unit 3. The motor 21 drives the coil unit 4 to rotate through the reducer 22 and the transmission unit 3 to realize the coiling operation of the cable.

[0026] In this embodiment, the reducer 22 rotates under the drive of the motor 21. The reducer 22 reduces the speed and increases the torque, thereby effectively winding the cable during the cable winding process, so as to avoid the overload of the motor 21 caused by the increased weight of the cable winding.

[0027] Furthermore, the two ends of the rotating shaft 41 are provided with rotating shaft mounting seats 42, and the rotating shaft 41 is mounted on the frame body 11 through the rotating shaft mounting seats 42.

[0028] This embodiment, by setting a rotating shaft mounting base 42, facilitates the installation and disassembly of the rotating shaft 41 and the entire coil unit 4, thereby facilitating the transportation, installation, disassembly, maintenance, and replacement of the entire coiling device.

[0029] Example 2:

[0030] Based on Example 1, referring to Figure 2 , 3 As shown, the transmission unit 3 includes a clutch connected to the output shaft of the power unit 2, a transmission shaft 34 connected to the clutch, and a drive gear 36 located at the end of the transmission shaft 34. The drive gear 36 is connected to a driven gear located on the rotating shaft 41 via a chain.

[0031] Furthermore, the clutch includes a stationary clutch 31 and a moving clutch 32. The stationary clutch 31 is connected to the output shaft of the power unit 2. The moving clutch 32 is slidably disposed on the transmission shaft 34 and can drive the transmission shaft 34 to rotate. The moving clutch 32 engages with the stationary clutch 31 to drive the transmission shaft 34 to rotate, and the moving clutch 32 disengages from the stationary clutch 31 to stop the transmission shaft 34 from rotating.

[0032] In this embodiment, by setting the transmission unit 3 and the clutch composed of the static clutch 31 and the dynamic clutch 32, the power of the power unit 2 can be conveniently transmitted to the coil unit 4 to smoothly complete the cable coiling operation. At the same time, the rotation of the coil unit 4 can be conveniently started and stopped, so that the cable coiling can be stopped without stopping the motor 21.

[0033] Furthermore, the moving clutch 32 is provided with a long key bar 321, and the transmission shaft 34 is provided with a long keyway 341 that matches the long key bar 321. The moving clutch 32 is slidably disposed on the transmission shaft 34 through the cooperation of the long key bar 321 and the long keyway 341 and can drive the transmission shaft 34 to rotate.

[0034] In this embodiment, the cooperation between the long key bar 321 and the long keyway 341 enables the moving clutch 32 to slide on the transmission shaft 34, thereby achieving engagement and disengagement with the stationary clutch 31. Simultaneously, due to the cooperation between the key bar and the keyway, after the moving clutch 32 engages with the stationary clutch 31, when the moving clutch 32 rotates under the drive of the stationary clutch 31, the moving clutch 32 can drive the transmission shaft 34 to rotate, thus realizing the function of a clutch.

[0035] Furthermore, the transmission unit 3 also includes a shift fork 33, which is used to engage or disengage the moving clutch 32 from the stationary clutch 31. Even further, the moving clutch 32 is provided with a shift groove 322, and the shift fork 33 is provided with a shift lever 332 that cooperates with the shift groove 322. The shift fork 33, through the cooperation of the shift lever 332 and the shift groove 322, drives the moving clutch 32 to slide on the transmission shaft 34, thereby engaging or disengaging the moving clutch 32 from the stationary clutch 31.

[0036] In this embodiment, the shift fork 33, the shift lever 332, and the shift groove 322 cooperate to enable the shift fork 33 to drive the moving clutch 32 to slide along the axial direction of the transmission shaft 34, that is, the moving clutch 32 slides along the direction defined by the long keyway 341 on the transmission shaft 34, thereby realizing the engagement and disengagement of the moving clutch 32 and the stationary clutch 31.

[0037] Furthermore, refer to Figure 2 As shown, the drive shaft 34 is mounted on the frame body 11 via the drive shaft mounting base 35, and the shift fork 33 is mounted on the frame body 11 via the shift fork mounting base 331.

[0038] In this embodiment, the transmission shaft mounting base 35 is provided with a bearing to support the transmission shaft 34 and ensure the coaxiality of the transmission shaft 34, thereby ensuring the smooth output of power from the power unit 2; the setting of the shift fork mounting base 331 can provide a hinge point for the shift fork 3, thereby providing the rotation axis for the shift fork 33 to move.

[0039] Furthermore, the transmission unit 3 also includes a chain box 37, which is mounted on the frame body 11 via a chain box mounting plate 38, and the chain is located in the chain box 37.

[0040] In this embodiment, the chain box 37 serves as a safety protection feature, preventing cables or other foreign objects from getting caught in the chain during cable coiling operations, and also ensuring the safety of the operators.
