Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] according to Figure 1 、 2 As shown in Figures 3 and 4, a construction cable retracting and releasing mechanism is proposed in this embodiment, comprising a support structure and a retracting and releasing roller group provided in the support structure;

[0025] The bracket structure includes two support plates 1, a fixing plate 2 is provided between the two support plates 1, and both ends of the fixing plate 2 are fixedly connected to the support plates 1;

[0026] The retracting roller assembly includes a reel 12, which is placed between the two support plates 1. Positioning plates 13 are provided at both ends of the reel 12. The positioning plates 13 and the reel 12 are fixedly connected by a fixed shaft. A placement slot 15 is provided on the side of the support plate 1 for placing the fixed shaft and allowing the fixed shaft to rotate.

[0027] A transmission device for driving the winding drum 12 to rotate is provided on the outer side of the support plate 1 , and the transmission device is detachably connected to the positioning plate 13 .

[0028] The transmission device controls the rotation of the winding drum 12, and the winding drum 12 winds the cable during rotation. The transmission device and the positioning disk 13 are detachably connected. When the fixation between the positioning disk 13 and the transmission device is released, the fixed shafts at both ends of the positioning disk 13 are removed from the placement grooves 15 opened on the support plate 1, and the winding drum 12 is easy to disassemble and assemble.

[0029] For the specific structure of the transmission device, please refer to the following description.

[0030] The transmission device includes a wheel bracket 10, which is fixedly connected to the side of the support plate 1 away from the winding drum 12. A wheel 11 is provided at the upper end of the wheel bracket 10, and the wheel 11 is rotatably connected to the wheel bracket 10. A belt drive is provided at the upper end of the fixed plate 2 for controlling the rotation of one of the wheels 11. A pin positioning part is provided on the wheel 11, and the pin positioning part is plugged into a positioning hole 16 opened on the positioning plate 13.

[0031] The rotating wheel 11 is plugged into the positioning disks 13 at both ends of the winding drum 12 through the pin positioning parts. When the belt drive part drives the rotating wheel 11 to rotate, the positioning disks 13 fixed to the rotating wheel 11 through the pin positioning parts will also rotate. The winding drum 12 is fixed to the positioning disks 13 through the connecting shaft, so the winding drum 12 will also rotate together to reel in the cable.

[0032] About belt drives:

[0033] The belt drive component includes a motor 3, a first pulley 4 and a fourth pulley 14. The mounting end of the motor 3 is fixedly connected to the upper end of the fixed plate 2. The first pulley 4 is fixedly connected to the output end of the motor 3. The fourth pulley 14 is fixedly connected to the side of one of the rotating wheels 11 away from the positioning plate 13. The first pulley 4 and the fourth pulley 14 are connected by a synchronous belt transmission.

[0034] The rotation of the take-up drum 12 is controlled by a belt drive. The motor 3 drives the first pulley 4, which in turn rotates the fourth pulley 14 via a synchronous belt. The rotating pulley 11 is fixed to the fourth pulley 14, and the positioning plate 13 is fixed to the rotating pulley 11 via a pin. When the fourth pulley 14 rotates, the positioning plate 13 and the take-up drum 12 also rotate. Of course, in addition to belt drives, chain drives can also be used as a drive, but we will not explain this in detail here.

[0035] About the pin locating parts:

[0036] The pin locating member includes at least two locating bolts 17, which pass through the runner 11 and are threadedly connected to the locating holes 16. The locating bolts 17 are evenly arranged in the circumferential direction of the axis of the runner 11. The locating plate 13 has a plurality of locating holes 16, which are evenly arranged in the circumferential direction of the axis of the locating plate 13. The locating holes 16 coincide with the axis of the runner 11.

[0037] Rotate the positioning bolt 17 and screw it into the corresponding positioning hole 16 on the positioning plate 13. When the wheel 11 rotates, the positioning plate 13 will also rotate. When the winding drum 12 is removed from the top, the fixation between the positioning bolt 17 and the positioning plate 13 can be released.

[0038] It is worth further explanation.

[0039] The retracting and retracting roller group also includes a limit rod 5, a reciprocating screw 6 and a limit block 7 arranged between the two support plates 1. The two ends of the limit rod 5 are fixedly connected to the two support plates 1, and the two ends of the reciprocating screw 6 are rotatably connected to the two support plates 1. The limit block 7 is sleeved on the outside of the reciprocating screw 6 and the limit rod 5. The limit block 7 is threadedly connected to the reciprocating screw 6. The limit block 7 is slidably connected to the limit rod 5. A belt transmission part for controlling the rotation of the reciprocating screw 6 is provided on the outside of the support plate 1.

[0040] Two wire rollers are provided on the top of the limit block 7. The wire harness to be wound passes between the two wire rollers. When the belt transmission part controls the rotation of the reciprocating screw 6, the reciprocating screw 6 cooperates with the limit block 7 during rotation. The limit block 7 moves back and forth along the reciprocating screw 6 and the rod body of the limit rod 5. The limit rod 5 guides the limit block 7. The limit block 7 evenly winds the cable around the outside of the winding drum 12 during the back and forth movement.

[0041] About belt drives:

[0042] The belt drive includes a second pulley 8 and a third pulley 9. The third pulley 9 is fixedly connected to the side of another rotating pulley 11 away from the positioning disk 13. The second pulley 8 is fixedly connected to one end of the reciprocating screw 6. The second pulley 8 is rotatably connected to the support plate 1. The second pulley 8 and the third pulley 9 are connected by a synchronous belt drive. When the winding drum 12 rotates, the positioning disks 13 at both ends of the winding drum 12 rotate with the rotating pulley 11. The third pulley 9 is fixed to the rotating pulley 11. When the third pulley 9 rotates, it moves with the second pulley 8 via the synchronous belt. The reciprocating screw 6 is fixed to the second pulley 8. When the second pulley 8 rotates, the reciprocating screw 6 also rotates. When the winding drum 12 reels the cable, the limit block 7 can simultaneously perform the cable arrangement operation.

[0043] To improve the safety of the winding drum 12 during operation, in a preferred embodiment, a stopper bolt 18 is provided at the upper end of the support plate 1, the lower end of which is inserted into the placement groove 15, and the stopper bolt 18 is threadedly connected to the support plate 1. After the fixed shafts at both ends of the winding drum 12 are placed in the placement groove 15, the stopper bolt 18 is rotated and screwed into the placement groove 15. The placement groove 15 can block the fixed shaft, preventing the fixed shaft from flying out of the placement groove 15 due to the pin positioning member falling off between the positioning plate 13 and the rotating wheel 11, which would cause a safety hazard.

[0044] How this application works:

[0045] The rotation of the take-up drum 12 is controlled by a belt drive, that is, the motor 3 drives the first pulley 4 to rotate, and the first pulley 4 pulls the fourth pulley 14 to rotate together through the synchronous belt during rotation. The rotating wheel 11 is fixed to the fourth pulley 14, and the positioning disk 13 is fixed to the rotating wheel 11 through a pin positioning member. When the fourth pulley 14 rotates, the positioning disk 13 and the take-up drum 12 will also rotate. The take-up drum 12 reels the cable during rotation, and the transmission device and the positioning disk 13 are detachably connected. When the fixation between the positioning disk 13 and the transmission device is released, the fixed shafts at both ends of the positioning disk 13 are removed from the placement groove 15 opened on the support plate 1, and the take-up drum 12 is easy to disassemble and assemble.
