New equipment and new cargo types are constantly increasing. Under the background of the rapid development of Binzhou Port production and construction, higher requirements are put forward for port production, and at the same time, higher requirements are put forward for the failure rate and intact rate of equipment. The inherent safety of equipment is an important link to ensure on-site production.

[0003] The use of the new equipment container rotary spreader has reduced the input of manpower, eliminated the unsafe behavior of manual support of the simple spreader before, and improved the safety of operation. However, some problems have also arisen. For example, during use, the location of the gantry crane is not a dedicated container berth, and the rotary spreader cable needs to be frequently disassembled. When retrieving the cable, the inaccurate positioning of the cable reel limit can easily cause over-retraction or under-retraction. Over-retraction will cause damage to the cable plug, greatly increasing the maintenance cost. Summary of the invention

[0011] As an improved technical solution, the limit switch is interlocked with the motor to a control system.

[0012] As an improved technical solution, sleeves rotatably connected to the two fixed shafts are respectively provided on the outer sides thereof.

[0013] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model provides a cable retracting device, including a cable reel, one end of the rotating shaft of the cable reel is connected to a motor, a fixing frame is provided at the bottom of the cable reel, two parallel fixed shafts are provided between the two upper longitudinal beams of the fixing frame, the cable line passes through the gap between the two fixed shafts and is wound on the cable reel, a limiting clamp is provided at the bottom of the two fixed shafts on the outside of the cable line, and the outer diameter of the limiting clamp is larger than the gap between the two fixed shafts.

When the limit clamp abuts against the lower part of one end of the fixed shaft, the fixed shaft and the first rotating sleeve are pushed to move upward along the path of the arc-shaped buffer groove, so that the spring is deformed to act on the limit switch. After receiving the signal from the limit switch, the control system stops the operation of the motor, thereby ending the collection and greatly avoiding the occurrence of over-collection.

[0018] The outer sides of the two fixed shafts are respectively provided with sleeves rotatably connected thereto. The rotatably arranged sleeves make it less likely for the cables to get stuck during collection, making collection smoother and also greatly reducing the possibility of damage to the cable skin.

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-6As shown, a cable retracting device comprises a cable reel 1, one end of the rotating shaft 2 of the cable reel 1 is connected to a motor 3, a fixing frame 4 is provided at the lower part of the cable reel 1, two parallel fixed shafts 6 are provided between the two upper longitudinal beams 5 of the fixing frame 4, in this embodiment, the direction of the fixed shaft 6 is perpendicular to the direction of the rotating shaft 2, a cable 7 passes through the gap between the two fixed shafts 6 and is wound on the cable reel 1, a limiting clamp 8 is provided at the lower part of the two fixed shafts 6 on the outer side of the cable 7, and the outer diameter of the limiting clamp 8 is larger than the gap between the two fixed shafts 6. After the cable passes through between the two fixed shafts 6, it is wound on the outer side of the rotating rod of the cable reel 1. By placing the limiting clamp 8 at the tail of the cable, it is convenient to observe the cable collection situation. When the cable is collected close to the limiting clamp 8, the motor 3 can be stopped immediately to avoid excessive collection.

[0029] The two upper longitudinal beams 5 are both provided with an annular cutout 9, and the first rotating sleeve 18 and the second rotating sleeve 19 are rotatably sleeved on the outer sides of the two cutouts 9, and the lower parts of the first rotating sleeve 18 and the second rotating sleeve 19 are both provided with a mounting seat 10, and the upper parts of the two mounting seats 10 are respectively provided with a fixing seat 11, and the inner sides of the two mounting seats 10 and the fixing seat 11 are both provided with an arc seat 12 adapted to the corresponding fixed shaft 6, and the corresponding mounting seats 10 and the fixing seats 11 are connected by bolts. The first rotating sleeve 18 and the second rotating sleeve 19 are rotatably arranged, and the buffering performance is strong, which reduces the possibility of equipment damage caused by the collision of the limit clamp 8 with the fixed shaft 6, and at the same time, the fixing seat 11 and the mounting seat 10 are convenient to disassemble and assemble, which is convenient for replacing the fixed shaft 6 and simple maintenance.

[0030] The first rotating sleeve 18 is provided with an arc-shaped buffer groove 13 adapted to the inner diameter of the cutout 9, a spring 14 is provided at the lower part of the mounting seat 10 near the first rotating sleeve 18, and the other end of the spring 14 is connected to a limit switch 15; the fixing frame 4 is provided with a fixing plate 16 at the lower part of the limit switch 15, and the limit switch 15 is fixedly connected to the fixing plate 16.

[0031] The limit switch 15 is interlocked with the motor 3 to the control system. When the limit snap ring 8 abuts against the lower part of one end of the fixed shaft 6, the fixed shaft 6 and the first rotating sleeve 18 are pushed to move upward along the path of the arc-shaped buffer groove 13, so that the spring 14 is deformed to act on the limit switch 15.
