Description

Technical Field

[0001] This utility model relates to the field of cable winding and unwinding technology, and in particular to a cable winding and unwinding device for electromechanical engineering. Background Technology

[0002] In electromechanical engineering, building construction, and temporary power supply applications, cable winding and management is a frequent and demanding task. Currently, most cable winding and unwinding devices on the market suffer from the following drawbacks: many existing devices lack automatic cable routing functions, or the cable routing mechanism is not synchronized with the winding and unwinding actions. When winding cables, manual guidance or simple guide rings are primarily relied upon, which easily leads to cable accumulation and tangling on the winding rollers. This not only results in uneven winding and excessive space occupation, but also easily causes tangling and knotting during unwinding, severely abrading or even tearing the cable insulation layer, shortening the cable's service life. Therefore, we propose a cable winding and unwinding device for electromechanical engineering. Utility Model Content

[0003] The main purpose of this utility model is to provide a cable winding and unwinding device for electromechanical engineering, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An electromechanical engineering cable take-up and unwinding device includes a base and a take-up roller.

[0009] By adopting the above technical solution, the reciprocating screw converts the rotary motion into linear reciprocating motion, driving the screw slider to move. The slider ensures smooth sliding and prevents jamming. This allows the pulley block to guide the cable to be evenly wound on the take-up roller during the take-up and unwinding process, avoiding cable accumulation, crossing or wear, and improving take-up and unwinding efficiency.

[0010] Preferably, a protective shell is provided on one side of the right-side upright plate, the servo motor is disposed inside the protective shell, and the worm gear meshes with the worm wheel.

[0011] By adopting the above technical solutions: the worm gear drive has a self-locking characteristic, which can prevent the take-up roller from rotating in the opposite direction when it stops, thus avoiding accidental cable loosening; the servo motor provides precise speed and torque control, which is suitable for different cable take-up and untake-up requirements and improves control accuracy; the slot cooperates with the take-up roller's locking block, allowing for quick installation and removal of the take-up roller; and the bolts are locked through threaded holes and fixing holes to ensure that the take-up roller will not loosen during high-speed rotation, thus improving safety and reliability.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model achieves efficient, stable, and safe cable winding and unwinding by using a servo motor-driven worm gear mechanism combined with a quick-assembly and disassembly take-up roller structure. Specifically, the worm gear transmission has a reverse self-locking characteristic, which can effectively prevent the take-up roller from reversing and loosening the cable due to its own weight or external force when the machine stops, thus improving operational safety. The servo motor provides precise speed and torque control to adapt to the winding and unwinding needs of cables of different specifications. At the same time, the take-up roller can be quickly engaged with the slot on the rotating shaft by a locking block and then locked with bolts, realizing the quick installation and disassembly of the take-up roller, which greatly improves the efficiency of roller changing and the convenience of operation.

[0016] 2. This utility model utilizes a single drive source and belt drive to synchronously drive the reciprocating cable laying and cleaning mechanisms, achieving automatic cable laying and synchronous cleaning. It boasts high functional integration and energy efficiency. Specifically, the rotation of the take-up roller's main shaft is precisely transmitted to the reciprocating lead screw via a synchronous belt. This drives the lead screw slider to move the pulley system in a uniform reciprocating motion, guiding the cable to wind neatly and evenly on the take-up roller, effectively preventing cable accumulation, crossing, and wear. Simultaneously, as the cable passes through the cleaning frame, the cleaning blocks positioned above and below, under the constant force of springs, adapt to cables of different diameters and effectively remove dust, dirt, and other adhering substances from their surfaces, maintaining cable cleanliness. The entire cable laying and cleaning process is completed automatically and synchronously with the take-up and unwinding actions, requiring no additional power source. Its compact structure and high degree of automation significantly improve the quality and efficiency of cable maintenance. Attached Figure Description

The position of the fixing hole 201 is adapted to the threaded hole 112. The shape and size of the fixing hole 201 are adapted to the bolt 113. The block 20 is disposed in the slot 111. One end of the bolt 113 passes through the threaded hole 112 and extends into the fixing hole 201. The bolt 113 is threadedly engaged with the threaded hole 112. A protective shell 106 is provided on one side of the right vertical plate 11. The servo motor 104 is disposed in the protective shell 106. The worm gear 105 meshes with the worm wheel 103.

[0024] Through the above scheme: the device is powered by the storage battery 10, which starts the servo motor 104. The worm gear 105 on the output shaft drives the worm wheel 103 mounted on the right rotating shaft 110. The transmission between the worm wheel 103 and the worm gear 105 has a large reduction ratio, which can provide strong torque and is suitable for winding and unwinding heavy cables. More importantly, it has a reverse self-locking characteristic, that is, the worm gear 105 can drive the worm wheel 103, but the worm wheel 103 cannot drive the worm gear 105 in the reverse direction. This ensures that during the winding process or when the machine stops, the take-up roller 2 will not reverse due to the tension of the cable, preventing the cable from accidentally coming loose. The rotating shaft 110 engages with the locking blocks 20 at both ends of the take-up roller 2 through the slot 111 on it, and is locked with bolts 113 inserted into the fixing holes 201.

When it rotates, the lead screw slider 122, which is threaded with it, will make horizontal, automatically reversing reciprocating motion along the lead screw and slider 121. A pulley group 123 is installed on the lead screw slider 122. The cable passes through the pulley group 123. Therefore, the reciprocating motion will guide the cable to wind evenly left and right on the take-up roller 2, avoiding the cable from being concentrated in one place and causing accumulation, crossing and wear. During the take-up and unwinding process, the cable will pass through the cleaning frame 13. The cleaning frame 13 is provided with two sets of cleaning blocks 133 at the top and bottom. The upper cleaning block 133 is installed on the pressure plate 131. The pressure plate 131 is pressed down by the spring 132. This structure of spring 132 and pressure plate 131 can adapt to cables of different diameters and always give the cleaning block 133, such as a brush or sponge, a constant pressure so that it fits tightly against the surface of the cable.

[0025] It should be noted that the device is powered by the storage battery 10. When the servo motor 104 is started, the worm gear 105 on the output shaft drives the worm wheel 103 mounted on the right rotating shaft 110. The transmission between the worm wheel 103 and the worm gear 105 has a large reduction ratio, which can provide strong torque and is suitable for winding and unwinding heavy cables. More importantly, it has a reverse self-locking characteristic, that is, the worm gear 105 can drive the worm wheel 103, but the worm wheel 103 cannot drive the worm gear 105 in the reverse direction. This ensures that during the winding process or when the machine stops, the take-up roller 2 will not reverse due to the tension of the cable, preventing the cable from accidentally coming loose. The rotating shaft 110 engages with the locking blocks 20 at both ends of the take-up roller 2 through the slot 111 on it, and is locked with bolts 113 inserted into the fixing holes 201. At the left end of the rotating shaft 110, a pulley 114 is provided. When the rotating shaft 110 rotates, the pulley 114 rotates synchronously. Through belt transmission, power is transmitted from the pulley 114 to the moving part. The pulley 124 at the end of the reciprocating lead screw 120 on the frame 12 is a special lead screw that converts rotary motion into linear reciprocating motion. When it rotates, the lead screw slider 122, which is threaded with it, will make horizontal, automatically reversing reciprocating motion along the lead screw and slider 121. A pulley group 123 is installed on the lead screw slider 122. The cable passes through the pulley group 123. Therefore, the reciprocating motion will guide the cable to wind evenly left and right on the take-up roller 2, avoiding the cable from being concentrated in one place and causing accumulation, crossing and wear. During the take-up and unwinding process, the cable will pass through the cleaning frame 13. The cleaning frame 13 is provided with two sets of cleaning blocks 133 at the top and bottom. The upper cleaning block 133 is installed on the pressure plate 131. The pressure plate 131 is pressed down by the spring 132.
