[0023] Please refer to Figure 1-5 The utility model discloses a convenient maintenance stranding machine in a preferred embodiment, including a base frame 1, a wire taking-up mechanism, a wire twisting mechanism and a moving mechanism; the wire taking-up mechanism includes a moving frame 2, a spindle box 3, a synchronous motor 4, a differential 5 and a wire taking-up drum 6; the moving frame 2 is slidably arranged on the base frame 1; the spindle box 3 is mounted on the middle top of the moving frame 2, and the spindle box 3 is a convex structure; the synchronous motor 4 and the differential 5 are arranged on the moving frame 2, and the synchronous motor 4 and the differential 5 are respectively located on both sides of the spindle box 3; the differential 5 is connected to the driving end of the synchronous motor 4 through a belt transmission; the wire taking-up drum 6 is rotatably arranged on one side of the spindle box 3, and the wire taking-up drum 6 is connected to the differential 5 through a belt transmission; the wire twisting mechanism includes a fixed box 7, a wire twisting motor 8, a synchronous rod 9 and a wire twisting arm 10; the fixed box 7 is arranged on the base frame 1 On the top, the fixed box 7 is a convex structure, which is symmetrically arranged with the spindle box 3; the stranding motor 8 is arranged on the outer top on one side of the bottom of the fixed box 7; the synchronization rod 9 is rotatably arranged on the base frame 1, and the synchronization rod 9 is respectively connected to the stranding motor 8 and the differential 5 through a belt; the stranding swing arm 10 is rotatably arranged on one side of the fixed box 7, and the stranding swing arm 10 is connected to the synchronization rod 9 through a belt; the stranding swing arm 10 is bent to form a convex structure; the stranding swing arm 10 is hollowed out to form a plurality of drag-reducing holes; the moving mechanism includes a moving motor 11 and a transmission screw 12; the moving motor 11 is arranged in the base frame 1; the transmission screw 12 is rotatably arranged in the base frame 1, and the transmission screw 12 is connected to the driving end of the moving motor 11; the transmission screw 12 is connected to the bottom of the moving frame 2.

[0024] Specifically, two movable guide rails 13 are symmetrically arranged on the base frame 1; sliders are symmetrically arranged on both sides of the bottom of the movable frame 2; the two sliders are slidably arranged on the two movable guide rails 13 respectively; the synchronous motor 4 and the differential 5 are respectively located above one of the movable guide rails 13.

[0025] Specifically, the moving mechanism also includes a balancing frame 14, and the transmission screw 12 is rotatably arranged in the balancing frame 14; a balancing plate 15 is arranged on the top of the balancing frame 14, and a guide groove is formed between the balancing plate 15 and the balancing frame 14; a balancing block 16 is arranged at the bottom of the moving frame 2; the balancing block 16 passes through the guide groove and is slidably arranged between the balancing frame 14 and the balancing plate 15; the bottom of the balancing block 16 is transmission-connected to the transmission screw 12.

[0027] As can be seen from the above, the synchronous motor 4, the differential 5 and the spindle box 3 share the pressure respectively by two movable guide rails 13 and a balancing guide rail 17, which reduces the force on the movable frame 2. At the same time, the balancing block 16 always moves between the balancing frame 14 and the balancing plate 15, thereby ensuring that the moving frame 2 moves smoothly without shaking or deviation.

[0028] Specifically, a guide rod 18 is provided at one end of the synchronization rod 9; guide grooves are evenly spaced on the outer side of the guide rod 18; a guide frame 19 is provided on one side of the bottom of the movable frame 2; a guide sleeve 20 is rotatably provided inside the guide frame 19; guide teeth are evenly spaced on the inner side of the guide sleeve 20; the guide sleeve 20 is sleeved on the outer side of the guide rod 18, and the guide teeth are slidably provided in the guide groove.

[0030] From the above, it can be seen that during the working process, the guide sleeve 20 can maintain synchronous movement with the mobile frame 2 during the rotation process through the guide groove and the guide teeth, and will not affect the transmission of the differential 5 and the synchronization rod 9, that is, the transmission coordination between the synchronous motor 4, the synchronization rod 9, the differential 5 and the twisting motor 8 always remains stable.

[0031] Specifically, a plurality of slot-type photoelectric sensors 22 are arranged on the base frame 1; a sensing plate 23 is arranged on one side of the mobile frame 2; and the sensing plate 23 is located on the sensing slot path of the plurality of photoelectric sensors 22. The moving distance of the mobile frame 2 can be accurately detected by the photoelectric sensors 22 and the sensing plate 23, so as to conveniently control the movement of the take-up reel 6 to evenly twist the wires.

[0032] Specifically, it also includes a loading and unloading mechanism; the loading and unloading mechanism includes a lifting frame 24, a lifting motor 25 and a lifting tray 26; the lifting frame 24 is arranged on one side of the base frame 2; the lifting motor 25 is arranged on the top of the lifting frame 24; the lifting tray 26 is slidably arranged on one side of the lifting frame 24, and the lifting tray 26 is connected to the driving end of the lifting motor 25 through a screw drive.

Except when the take-up reel 6 needs to be pushed out of the loading and unloading groove for recovery, the retaining frame 29 must be installed at the exit of the loading and unloading groove at other times to prevent the take-up reel 6 from suddenly falling into the loading and unloading groove and then automatically rolling out during the lifting process, thereby avoiding safety hazards.

[0035] Furthermore, the base frame 1, the mobile frame 2, the main shaft box 3, the take-up drum 6, the fixed box 7 and the loading and unloading groove are all symmetrically arranged on both sides along the central axis of the rotating shaft of the take-up drum 6. Therefore, the positions of the loading and unloading mechanism and the retaining frame 29 can be exchanged during assembly without affecting the loading and unloading of the take-up drum 6 and the winding of the cable, so that according to the requirements of factors such as the work site, the specific positions of the loading and unloading mechanism and the retaining frame 29 can be exchanged independently to determine whether the take-up drum 6 is installed and unloaded through the left side of the loading and unloading groove or the right side of the loading and unloading groove.

[0036] It can be seen from the above description that the utility model is convenient for installation and maintenance, and the belt is also very convenient to replace. At the same time, the overall working process is safe and stable.
