A guide rod 9 is installed between the two symmetrical inner sidewalls of the support plate 2, and sliding blocks 8 are installed on the reciprocating screw 7 and the guide rod 9 to improve... To ensure smooth cable winding and unwinding with precise motion, a transmission chain 10 is installed on the outer side of the device support plate 2. This chain connects the rotating winch 3 and the reciprocating screw 7, which are wound around the winch rod 12 of the rotating winch 3, enabling synchronized movement and improving work efficiency. A rotating gear 11 is mounted on the winch rod 12 and located on the side of the rotating winch 3, meshing with the transmission chain 10 to further ensure the synchronicity of cable winding and unwinding. A ratchet pawl 13 is provided on the side of the device support plate 2 near the coil spring 6 to prevent sudden slack in the cable due to external force during winding and unwinding, improving safety. A support frame 14 is provided at the lower end of the device support plate 2 to enhance the stability of the overall structure. A base 15 is provided at the bottom of the device support plate 2 for easy fixing and installation of the device. An anchor plate 16 is provided on one side of the base 15, and bolts 17 are provided at the connection between the base 15 and the anchor plate 16 to further ensure the stability of the device and adapt to various working environments.

[0044] In this utility model, preferably, a suspended cable 1 is provided on the outer side of the rotating winch 3. The rotating winch 3 includes a winch wheel 31, a winch shaft 32, and a winch rod 12. The winch shaft 32 is perpendicular to the device support plate 2, and the winch wheel 31 faces outward. The slip ring energizer 4 includes an energizer protective cover 41 and a carbon brush contact type slip ring 42. The energizer protective cover 41 is fixed on the device support plate 2 and located on one side of the winch rod 12. The carbon brush contact type slip ring 42 is connected to the winch rod 12. The roller-type cable inlet / outlet 5 includes a slip ring 51 and a slip ring reinforcement 52. The spring coiler 6 includes a spring coiler housing 61 and a spring 62. The spring coiler housing 61 is connected to the device support plate 2, and the spring 62 is welded to the winch rod 12. The spring coiler 6 is opposite to the rotating winch 3. 1. Fixed on the device support plate 2, the coil spring 62 is connected to the winch rod 12. The reciprocating screw 7 is connected to the rotating gear 11 on the winch rod 12 through the transmission chain 10. The reciprocating screw 7 is parallel to the device support plate 2 and located in the middle of the device support plate. It is connected to the rotating winch 3 through the transmission chain 10. The winch rod 12 connects the rotating winch 3 and the coil spring 6, passes through the device support plate 2, and is connected at one end to the winch wheel 31 and at the other end to the coil spring 62. The ratchet and pawl 13 includes a ratchet 131 and a pawl 132. The ratchet 131 is mounted on the winch rod 12, and the pawl 132 is fixed on the support frame 14. The rotating winch 3, through the cooperation of the winch wheel 31, the winch shaft 32, and the winch rod 12, can realize the winding and release of the suspended basket cable 1, providing power. The cable winding and unwinding system provides a power source, ensuring orderly cable winding and unwinding, avoiding problems such as cable tangling and knotting during use, and improving cable efficiency and safety. The slip ring power supply 4 contains a power supply protective cover 41 and a carbon brush contact slip ring 42, ensuring stable power transmission. Simultaneously, the protective cover 41 protects the carbon brush contact slip ring 42 from dust and impurities, extending its service life and ensuring reliable power transmission. The roller-type inlet / outlet 5, through the slip ring 51 and slip ring reinforcement 52, makes the cable smoother when entering and exiting the device, reducing friction between the cable and the device, lowering the risk of cable wear, and increasing the cable's service life. The coil spring 6, utilizing the elastic energy storage characteristics of the coil spring 62, automatically stores energy when the cable is released and releases it during retrieval, assisting the winch in cable retrieval and improving the automation and efficiency of cable release and retrieval. It also reduces safety hazards such as scraping caused by untimely cable retrieval. The reciprocating screw 7, in conjunction with the transmission chain 10, transmits power between the rotating winch 3 and the reciprocating screw 7. The rotation of the reciprocating screw 7 drives the reciprocating motion of the sliding block 8, further ensuring the uniformity and stability of cable release and retrieval, preventing problems such as tangling and knotting during the process. The ratchet and pawl 13, through the cooperation of the ratchet 131 and pawl 132, automatically brakes the cable after it has been released to a certain length.To prevent dangerous situations caused by excessive cable release, and to ensure the stability and reliability of the cable during the recovery process, thereby improving the safety performance of the device.

[0045] The working principle and usage process of this utility model are as follows: In use, the device support plate 2 is fixed to the base 15 with bolts 17. The base 15 is anchored to the ground with anchor plates 16 to ensure device stability. Next, the cable is passed through the roller-type inlet / outlet 5, ensuring it passes through the slip ring 52 during entry and exit to reduce friction and damage. During initial setup, the coil spring 6 must be in its initial energy storage state, and the sliding block 8 is in the starting position of the reciprocating screw 7. When the suspended platform needs to be lowered for cable release, the cable is pulled out, driving the winch 3 to rotate. At this time, the coil spring 62 stores energy, and the sliding block 8, driven by the reciprocating screw 7, moves forward... The reciprocating motion ensures even cable release. Once the cable reaches the set length, the ratchet 131 and pawl 132 automatically brake to prevent the cable from retracting itself. When the basket rises and the cable needs to be retracted, the coil spring 62 releases its stored energy, driving the winch 3 to rotate and achieve automatic cable retraction. The sliding block 8 also reciprocates under the drive of the reciprocating screw 7 to ensure even cable winding. Throughout the entire operation, it is necessary to regularly check the connections and wear of each component, especially the slip ring power supply 4 and the coil spring 6, to ensure the reliability of power transmission and energy storage release and to guarantee the normal operation of the device.
