The invention relates to the field of technology and can be used to connect the towing vehicle and the towed object without departing crews of the vehicles in the areas of fire, infections and fires.

A device for coupling an armoured repair and recovery vehicle (BRAM) banabhatta. This device includes controlled from the inside of the machine the arm is reinforced rod, pivotally connected to the lever, with the possibility of rotation in the vertical plane and locks into several positions. At the other end of the lever reinforced spring-loaded capture forcipate type, in which is mounted one eye of the tow rope, and the other eye is mounted on the towbar BRAM (see ed.St. N 196156, class B 60 D 1/is th inside of the machine arm, to which one end attached to the rod, the other end of the rod is performed sector by sector articulated arm with hooks for tow ropes so that the axis of the grippers parallel and spaced apart a distance greater than the width of the loops of ropes and grabs displaced along these axes relative to each other at a distance less than the loop length between the grips and cables installed cylinders, which are placed in the two branches of the rope, forming a loop for snapping on the towbar of the object inside the cylinder is made of a longitudinal cavity for placement of the branches of the cable, and the outer surface of the cylinder is supplied with clamps for installation of loops in the hooks. Grips made in the form of tubes with stoppers that prevent the movement of the cylinder with rope in the direction of BRAM, and in the lower part of the pipe is made of a continuous longitudinal grooves, the width of which is smaller than the cylinder diameter, and greater than the diameter of the cables (see patent N 2038225 on request N 93018647 from 08.04.93 year).

When using this device as a pointing device is used Coulter-bulldozer (BRAM).

If the pulling force on the hook of the car less effort required for towing or pulling the object, use the winch, the cable which connect with zvezdnogo device is small traction winch, not allowing you to pull the object during jams and tow objects with a jammed chassis.

The present invention is to improve the reliability of the lifting and towing of cars after hitch.

The problem is solved in that the levers hitch fixed block sheave pulleys, which has the ability to rotate in horizontal and vertical planes, and the other ends of the cables hitch connected with bicornuate hook sheave pulleys.

In Fig. 1 and 2 the device and displayed: 1 - recovery vehicle; 2 winch with cable; 3 Coulter-bulldozer; 4 - towbar machine; 5 arms with grippers for towing ropes; 6 - towing rope; 7 brakes seizures; 8 roller sheave pulleys; 9 spring unit; 10 two-horned hook; 11 latch hook; 12 staples.

In the initial position, the levers 5 are installed on the vomer-the dozer 3 evacuation machine 1, block sheave pulleys mounted on the levers springs 9, allowing the rotation of the block in the horizontal and vertical planes, the winch cable 2 is passed through the roller 8, is connected to the hook 4 and stretched, the cable 6 one ends are connected with clamps and fastened them with brakes 7, the other ends of the cables connected to the two-horned Cruchot to the object, loop cables 6 alternately snapped at him tow hooks and alternately released from the grippers 4 when driving back from the object, the opener-the dozer 3 is lowered, the machine pulls back with the simultaneous unwinding of the winch cable 2. The strength of the tension cables overcomes the resistance of spring 9 and the block of pulley moves the lever 5 from the machine. Bracket protects the stoppers 7 from damage to the unit. After check-out to the desired distance Coulter-bulldozer uticaod into the soil and begin winding rope for pulling or towing the object. If necessary, the operation of winding and unwinding of the winch cable can be repeated for the evacuation of the object from the danger zone.

This device allows to increase the reliability of evacuation vehicles from dangerous areas.

Device for coupling recovery vehicle with a towed object containing controllable from inside the machine winch and Coulter-bulldozer, attached to the arms with grippers for the tow cables so that the axis of the grippers parallel and spaced apart a distance greater than the width of the loop of cable between the grips and cables installed slotted cylinders, which are placed in the two branches of the rope, forming a loop for snapping up the tow Et cylinders equipped with clamps for installation of loops in the hooks, which are made in the form of a pipe with stops preventing movement of the cylinder with rope to the side of the machine, at the bottom of the pipes made a solid longitudinal grooves, the width of which is smaller than the cylinder diameter, and greater than the diameter of wire rope grips are the brakes, holding the cylinders to the walls of the grippers in the direction perpendicular to their axis, characterized in that the levers fixed block sheave pulleys can be rotated in horizontal and vertical planes, and the other ends of the cables connected to the two-horned hook Poliplast.

FIELD: trainer engineering.

SUBSTANCE: the device contains the object of evacuation with a tow gear and a traction engine with a manipulator controlled from the traction engine, the object being fixed on the ground. The tow gears are fixed on the object with the possibility of changing their position relative to the ground. The manipulator has a lever with a detent device for placing the towline with a yoke. The detent device, in its lower part, has a through longitudinal slot, the width of which is larger than the diameter of the towline but smaller than that of the yoke. The towline is fixed on the traction engine so that it can be removed from the traction engine after connecting to the tow gear of the object.

EFFECT: time and cost saving, increased driver training safety.

SUBSTANCE: proposed method of retrieving vehicle with the help of retriever comprises connecting first end of tow rope with retriever towing hook or the first end of second tow rope with retriever winch rope. Manipulator controlled from inside the retriever accommodates parts of tor ropes. Then retriever is moved towards vehicle to be retrieved, second end of the first or second tor rope is jointed to vehicle towing hook by manipulator lever. Retriever tensions appropriate tow rope and the latter is uncoupled from manipulator and its lever. Now vehicle is towed or retrieved. Central part of every tow rope is arranged to allow adjustment of friction and elastic forces. Electrode is arranged in retriever body on the first tow rope or on winch rope and electrically connected with retriever inside frame. Emergent release from retrieved vehicle is made by cutting appropriate rope with the help of electrode. Proposed device comprises two tow ropes connected with retriever, one connected with towing winch, and manipulator with lever control from inside the vehicle.
