Description
Technical Field
The invention belongs to the field of engineering machinery hoisting, traction operation and vehicle rescue, and particularly relates to an electro-hydraulic control constant-tension winch with a rope storage device.
Background
The winch is a hoisting and traction device for self rescue and rescue of vehicles or equipment. At present civilian rescue vehicle and military rescue are equipped to use hydraulic capstan mostly is single-cylinder capstan winch and the permanent pulling force hydraulic capstan of two friction drums, wherein:
the single-drum winch is characterized in that a winding drum fixedly connected with an output mechanism of a speed reducer is driven by a motor, a rope (including a steel wire rope, the same applies below) wound on the winding drum is driven by the winding drum to move, so that tension output is realized, and the single-drum winch changes along with the change of a wound rope layer in the working process, so that the working radius of the winding drum changes; because the rotating speed and the output power of the motor are fixed, the rotating speed and the output torque of a drum of the winch are fixed, the change of the working radius of the drum leads to the change of the speed and the output tension of the rope, and the rope at the innermost layer of the drum has the maximum output tension and the minimum speed in the dragging and pulling processes of the winch; with the increase of the rope layers on the winding drum, the output tension is smaller and smaller, the rope speed is larger and larger, the requirements on the tension and the speed of the winch under the actual hauling and traction working conditions are not matched, and the design value of the tension of the single-drum winch and the length of the rope are limited; secondly, as the ropes are all wound on the winding drum, the ropes of all layers are mutually extruded in the working process, and the service life of the ropes is seriously influenced; in addition, the single-drum winch has no special rope arranging device, and the rope on the drum is often jumbled during use, so that the extrusion and the damage of the rope are aggravated.
A double-friction roller constant-tension hydraulic winch drives two friction rollers through a motor and a transmission mechanism, or respectively drives the two friction rollers through the two motors, and outputs output torque through the friction between the friction rollers and a rope to realize constant-tension output through the rope. Common rope storage devices are a coiled rope storage and a coiled rope storage, respectively. The rope storage device of the winding type is characterized in that power is transmitted to the rope storage winding drum from the friction roller through the mechanical transmission mechanism, the adjustment of a rope between the friction roller and the rope storage winding drum is realized through the slipping torquer, the rope is guaranteed to be orderly arranged on the rope storage winding drum through the rope arranging device, and rope disorder is prevented. The rope storage mode is limited by the transmission distance and space of the mechanical transmission mechanism, and the rope storage device must be arranged in a close distance with the friction roller, so that the vehicle-mounted performance of the winch is limited and influenced; in addition, the friction plate of the slipping torquer is in a slipping state for a long time and is easy to wear and lose efficacy. The coiling type rope storage device utilizes the rigidity of the rope to realize the in-and-out of the rope in the rope storage barrel, mechanical transmission machinery between the friction roller and the rope storage barrel is cancelled, but a rope guide device must be arranged between the friction roller and the rope storage barrel, and the rope enters the rope storage barrel to ensure a proper rope inlet angle, so that a plurality of limiting factors are provided for a winch in the arrangement space, and the vehicle-mounted performance and the installation convenience of the winch are influenced to a certain degree.
In addition, the traction and tension integrated machine used in the current electric power system has no braking function on the rear rope storage device, generally, hydraulic damping is arranged in the rope storage device, and the main machine is utilized to pull the rope storage device with the hydraulic damping, so that the tension of the electric wire and the cable between the rope storage device and the tension machine is realized. By the mode, when the traction machine stops for too long time, hydraulic damping is reduced or disappears due to leakage of the valve body, and the wire and the cable between the rope storage device and the traction machine are loosened and slipped.
