The invention relates to military equipment, mostly armored and armored engineering, and can be used to connect engineering machine razgrazhdeniya (WRI) and the towed object without departing crews from the machine in the areas of fire, intrusion and fire.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 plogo type, in which is mounted one ladle of the tow rope, and the other bucket is mounted on the towbar BRAM (and.with. N 196186 in class. B 60 D 1/10).It is also known a device for coupling BRAM with brontobytes. This device includes controlled from the 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 capture. Grips made in the form of tubes with stoppers that prevent the movement of the cylinder with rope towards BRAM, 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 cables (RF patent N 2038225, B 60 D 1/26, 93, a).When using this rojstva is a small number of degrees of freedom Coulter-bulldozer which makes it difficult to capture, as well as the inability to carry out polypody evacuated machine.The objective of the invention is to improve the reliability of evacuation damaged and betacyanin machines.The task is solved in that on the cheeks of the manipulator WRI attached a few levers with arms with aligned holes, parallel levers, brackets spaced along the lever at a distance greater than the width of the cheeks of the manipulator, and the holes and finger cheeks are connected by a rod, in which the latter is fixed by the stoppers, the dewatering of the lever from the outer surface of the cheeks.In Fig. 1 presents a General view of the device for coupling WRI; Fig. 2 - design and mounting of the levers on the cheeks WRI; Fig. 3 and 4 the design of the grip of Fig. 5 operation of the device at the coupling WRI with wheeled machine.In Fig. 1-5, the following notation: 1 building WRI, 2 caterpillar mover; 3 towbar, 4 rotating tower operator, 5 - telescopic boom, 6 hoist boom 7, the lifting mechanism cheeks manipulator, 8 the mechanism of rotation of the cheeks, 9 the mechanism of the cheeks, 10 - evacuated object 11 big cheek manipulator, 12 small cheek of the arm 13 of the lever right, 14 left arm, 15 the reference, 20 plate resistant, 21 capture the right lever 22 capture of the left lever 23 of the first cable, the second cable 24, 25 clamp, 26 split cylinder 27 screw, spacer 28, 29 stop 30 limiter right, 31 limiter left, 32 spring 33 bolt, nut 34 of the stopper cylinder 35 washer, nut 36 of the rod.Before transporting the device on the end of the cable 23, the opposite eye, the clip 25 is formed a loop of rope. On the other side of the clamp on the two branches of the wire overlap half of the split cylinder 26 between the rope and the cylinder proper spacers 28. The cylinder halves are drawn together and stopped on the cable with the screws 27.The cable 24 is going the same way.In the transport position, the levers 13 and 14 with brackets 15 and 16 and the hooks 21 and 22, the rods 17 and 18, the bolts 19, plate 20 and the cables 23 and 24 are stacked and fixed on WRI.When holding the device in the working position of the lever 13 with the brackets 15, spaced along the lever at a distance greater than the width of the cheeks, and having coaxial apertures, connected with the large cheek 11 of the manipulator WRI rod 17 which passes through holes and the inside of the finger cheeks. From the drop rod is secured by a washer 35 and nut 36. Then the rod is now the bolts 19 and distesa tow hook 3, fixed to the body 1 WRI. Slotted cylinder mounted on the other end of the cable is inserted in a fixed position with the end face of the grip 21 to the stop 29 and now spring 32, biasing the bolt 33 through the nut 34.The lever 14 with the bracket 16 is connected with a small cheek 12 of the manipulator rod 18 in the same way.The second cable 24 is connected to a tow hook and gripper 22 of the left arm similar to the first rope.Loop cables with cylinders recorded in the grips vertically or horizontally depending on the location of the planes towing hooks of the towed object or other towing items.The engine is started WRI and is powered telescopic boom 5, mounted on a rotating tower 4.Maneuvering tracks 2, WRI approaching the towed object and using the mechanisms of the extension boom lifting boom 6, the lifting of the cheeks 7, rotation of the cheeks 8 and disclosure cheeks 9, the loop of the first wire nakalyaetsya on the tow hook or other part of the towed object 10.After snapping the loop decreases the boom and the gripping device moves along the cylinder in the direction of WRI. If the cylinder of the gripping cylinder with rope pam the diameter of the cylinder, and greater than the diameter of the rope. The right cable is connected to the hook of the towed object and disconnected from the device.Similarly connect the left rope to the object.Then, if evacuated unmanaged object, cheeks manipulator disclosed, down and closed, covering the cables. After this boom is raised, the cables are tightened and the towed object partially posted. Using the tracked propulsion, WRI tows object polypolygon.This device allows to increase the reliability of evacuation of various objects from the dangerous areas, as the hitch is a manipulator with multiple degrees of freedom and a powerful boom with air capture allows you to tow hanging objects.The boom design allows WRI move with the device shown in its working position without restrictions on the mobility of the machine. The lifting capacity of the boom at minimum radius allows towing with polypolygon most trucks. Device for coupling engineering machine razgrazhdeniya with towed object containing controlled from the inside of the machine manipulator other and spaced apart by a distance the greater the width of the loops of rope, and each capture is hosted on two performed with longitudinal internal grooves of the half, covering the two branches of the wire forming the loop of the tow hook towed object, with the semi-cylinders made with clip branches rope and interaction with existing seizure stops, prevents movement of the semi-cylinders with cables in the side of the machine, with the lower surface of each grip is made with a longitudinal opening, the width of which is smaller than the transverse size of two semi-cylinders, and greater than the diameter of the cable, characterized in that the semi-cylinders made with the possibility of preload to the walls of the grippers by means of bolts in the direction perpendicular to the axes of the semi-cylinders and levers are made with the ability to install them on the machine by means of brackets mount to which the pointing device is made by means of rods, each of which is located in the holes of the two arms, the axis of which is aligned between and parallel levers, and each rod is made to lock in the arm through the stopper, the dewatering at the same time the lever from the outer surface of the manipulator.
