Description

Technical Field

[0001] The present invention relates to the technical field of automobile rescue equipment, and in particular to an adaptive intelligent torque precision control automobile winch. Background Art

[0002] Traditional automobile winches mostly use fixed gear adjustment or purely manual control torque adjustment methods. Taking the common mechanical gear winch as an example: users need to judge the size of the traction load based on experience in advance, and manually switch gears to adjust the output torque. However, the load conditions in field rescue scenarios are complex and changeable. The actual resistance of trapped vehicles is difficult to estimate due to environmental factors such as silt, sand and gravel. When the torque selected by the gear is too large, the instantaneous overload can easily cause the rope to break. At the same time, excessive torque will also cause the winch gear set to bear abnormal stress, resulting in tooth surface wear, tooth breakage, and even motor burnout and other faults; if the torque selected by the gear is too small, the winch cannot overcome the load resistance, which not only wastes rescue time, but may also cause motor overheating due to long-term inefficient operation, reducing the service life of the equipment.

[0003] In addition, manual control relies on the operator's experience and reaction speed. During emergency rescue, delays in manual judgment may result in missing the best time for rescue. Existing winches generally lack real-time monitoring devices for key parameters, and most products are not equipped with tension sensors, making it impossible to directly obtain the actual force conditions of the rope. During the traction process, if the towed object suddenly gets stuck or the terrain changes, causing a sudden increase in resistance, it is difficult for the operator to detect it in time, and continued operation may cause the winch to continue to operate under overload. Summary of the Invention

[0004] The purpose of the present invention is to provide an adaptive intelligent torque precise control automobile winch to solve the problems raised in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an adaptive intelligent torque precision control automobile winch, comprising a winch frame, a winch seat fixed to the winch frame by a plurality of bolts, a roller assembly provided between the winch seats, a rope wound around the roller assembly, one end of the rope connected to a hook assembly, a power assembly provided on one side of the winch frame, the power assembly meshing with a deceleration and torque-increasing assembly, one side of the deceleration and torque-increasing assembly meshing with a planetary gear assembly, and the deceleration and torque-increasing assembly and the outer sides of the planetary gear assembly both meshing with an adaptive control assembly; The top of the capstan seat is symmetrically provided with partitions, and a plurality of reinforcement rods are fixed between the partitions by bolts.

When the tension value monitored by the tension sensor exceeds the basic tension value range, the value fed back by the speed sensor drops rapidly, and the rescue efficiency decreases. The PLC controller controls the torque-increasing clutch to be energized, while the basic torque clutch and the saturation clutch are powered off. Similarly, when the tension value monitored by the tension sensor exceeds the enhanced tension value range, the PLC controller controls the saturation clutch to be energized, while the basic torque clutch and the torque-increasing clutch are powered off to continue the rescue.

Due to the fixed setting of the basic gear ring, the basic gear rotates around the central shaft while rotating, and then drives the linkage gear to rotate through the linkage plate. The larger sawtooth ratio is used to reduce the speed, thereby increasing the torque, improving the traction, and improving the rescue effect of the winch.

When starting traction, the PLC controller 24 first controls the basic torque clutch 811 to be powered on, while the torque increasing clutch 812 and the saturation clutch 813 are in a power-off state, at this time, the electromagnetic force is generated in the coil inside the basic torque clutch 811, thereby attracting the armature to drive the outer sleeve of the connecting gear 84 to be close to the inner sleeve of the control gear 82, so as to form a violent extrusion on the friction plate between the two, the gear 84 and the control gear 82 form an integral whole under the action of friction, the tension sensor 44 between the hook 41 and the rope 31 monitors the tension of the winch in real time and feeds back to the PLC controller 24; When the tension is in the basic tension value range, the linkage gear 75 drives the driving gear 84 of the basic torque clutch 811 to rotate, the driving gear 84 drives the rotating gear 34 at one end of the drum 32 through the control gear 82, thereby making the drum 32 rotate at both ends on the bearing 35 to wind the rope 31, realizing the effect of pulling the rescued vehicle; During rescue, the drum 32 drives the detection gear 38 to rotate, the detection gear 38 drives the driven gear 36 to rotate, the rotating speed of the driven gear 36 is transmitted to the rotating speed sensor 37 in real time through the shaft coupling, and the rotating speed sensor 37 feeds back to the PLC controller 24, the PLC controller 24 controls the output power of the servo motor 51 through the data information of the rotating speed, so as to avoid the collision caused by the too fast rotating speed affecting the rescue safety and the too slow rotating speed affecting the rescue efficiency; When the tension value monitored by the tension sensor 44 exceeds the basic tension value range, the value fed back by the rotating speed sensor 37 rapidly decreases at this time, the rescue efficiency is reduced, the PLC controller 24 controls the torque increasing clutch 812 to be powered on, while the basic torque clutch 811 and the saturation clutch 813 are powered off, at this time, the linkage gear 75 on one side of the chassis 61 drives the sun gear 72 to rotate, the sun gear 72 drives the planetary gear 73 to rotate in the inner gear ring 71 while rotating around it, the torque is further increased through the sawtooth transmission ratio, the traction is enhanced, and the linkage of the driving gear 84 and the control gear 82 on both sides of the torque increasing clutch 812 is realized, the drum 32 is continuously wound, and efficient rescue is realized; Similarly, when the tension value monitored by the tension sensor 44 exceeds the enhanced tension value range, the PLC controller 24 controls the saturation clutch 813 to be powered on, while the basic torque clutch 811 and the torque-increasing clutch 812 are powered off to continue the rescue, and when the car rescue returns to the flat position, the tension value monitored by the tension sensor 44 rapidly decreases, and the PLC controller 24 controls the basic torque clutch 811 to be powered on again, thereby realizing the self-adaptive intelligent torque precise control of the winch; When the rescued car is suddenly stuck, and the value detected by the tension sensor 44 exceeds the threshold of the winch load, the load protection assembly 9 is additionally arranged in the installation box 23, and the PLC controller 24 immediately powers off the servo motor 51, so that the drum 32 loses the traction and rotates, thereby driving the spiral gear 91 to rotate, and at this time, the anti-reverse rod 92 rotates around the rotating rod 93 under the elastic force of the return torsional spring 94, so that the anti-reverse rod 92 just abuts against the tooth gap of the spiral gear 91, preventing it from continuing to rotate, avoiding the falling of the rescued car, and avoiding the long-time overloading operation of the servo motor 51, after the stuck point of the car is handled, the servo motor 51 is restarted for rescue, which greatly improves the service life of the winch; When it is necessary to stretch the rope 31 to make the drum 32 rotate, the electric telescopic rod 95 can be started to drive the sliding rod 96 to move horizontally, thereby driving the anti-reverse rod 92 to move out of the tooth gap between the spiral gear 91.
