The first cable end portion is provided with a tension sensor.

[0007] A second tow rescue winch is arranged on the vehicle body of the tow rescue vehicle. The second cable end portion led out of the second tow rescue winch passes through a guide monitoring assembly arranged at the top end of the mast on the tow rescue vehicle and is connected to the hook component. The second tow rescue winch has an angle monitoring portion for monitoring the angle of the second cable between the second tow rescue winch and the guide monitoring assembly in real time. The guide monitoring assembly is used for monitoring the pressure from the second cable in real time.

[0008] A matched controller is used for calculating the tension of the second cable according to the data of the guide monitoring assembly and the angle monitoring portion, and adjusting the first tow rescue winch or the second tow rescue winch so that the tension of the second cable is equal to the tension of the first cable.

[0009] In a possible implementation manner, the fixed pulley and the guide monitoring assembly are arranged at intervals along the width direction of the tow rescue vehicle.

[0010] In a possible implementation, the hook component is provided with a guide wheel for winding and guiding the first cable; and the hook is provided with a connecting end for hanging the end of the second cable.

[0022] a driving motor fixed on the extending arms and power-connected with the reciprocating screw.

[0023] In a possible implementation, the guide monitoring assembly comprises:

[0051] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0052] Please refer to Figure 1 , the double winch synchronous coordination operation system provided by the present application will be described.

[0053] The towing and rescue vehicle usually sets a foldable bracket at the tail of the vehicle body 50, which can provide a vertical mast 60 during work, and the cables on the two winches are extended outward after passing through the fixed pulley set at the top of the mast 60, so as to ensure that a vertical pulling force is also provided to the rescued vehicle during towing. The cable wound by one of the winches is extended reversely to the vehicle body 50 through a fixed pulley connected with the hook, which can be seen from Figure 2 The pulling force of the cable is relatively easy to monitor, and the extension end of the other cable is directly connected with the hook. The pulling force of the cable is not easy to monitor due to the inconvenience of installing a pulling force sensor, so it is not easy to monitor the pulling force of the cable during work. Therefore, it is not possible to ensure that the pulling forces of the two cables are basically consistent, and thus it is not possible to realize synchronous operation, which will affect the service life of a single winch.

[0054] In summary, the double winch synchronous coordination operation system provided by the embodiment comprises a first towing and rescue winch 10, a second towing and rescue winch 20 and a matched controller. The first towing and rescue winch 10 is arranged on a vehicle body 50 of a towing and rescue vehicle. An end of a first cable 11 led out of the first towing and rescue winch 10 is sequentially passed through a fixed pulley arranged at a top end of a mast 60 of the towing and rescue vehicle, connected to a hook component 40 on a vehicle to be rescued and then reversely extended and connected to the vehicle body 50 of the towing and rescue vehicle. The end of the first cable 11 is provided with a tension sensor. The second towing and rescue winch 20 is arranged on the vehicle body 50 of the towing and rescue vehicle. An end of a second cable 29 led out of the second towing and rescue winch 20 is connected to the hook component 40 after passing through a guiding and monitoring assembly 30 arranged at the top end of the mast 60 of the towing and rescue vehicle. The second towing and rescue winch 20 is provided with an angle monitoring part for monitoring the angle of the second cable 29 between the second towing and rescue winch 20 and the guiding and monitoring assembly 30 in real time. The guiding and monitoring assembly 30 is used for monitoring the pressure from the second cable 29 in real time.

[0055] The controller calculates the tension of the second cable 29 according to the data of the guiding and monitoring assembly 30 and the angle monitoring part and adjusts the first towing and rescue winch 10 or the second towing and rescue winch 20 to make the tension of the second cable 29 equal to the tension of the first cable 11.

[0056] Compared with the prior art, the first cable 11 led out of the first towing and rescue winch 10 is connected to the vehicle body 50 of the towing and rescue vehicle after passing through the fixed pulley and the hook component 40, so that the tension sensor can be located near the vehicle body 50, which is convenient for electrical connection and real-time monitoring of the tension and can reduce the tension of the first cable 11. The second cable 29 led out of the second towing and rescue winch 20 is directly connected to the hook component 40, and the guiding and monitoring assembly 30 and the angle monitoring part arranged thereon can monitor the angle of the second cable 29 between the second towing and rescue winch 20 and the guiding and monitoring assembly 30 in real time and can also monitor the pressure from the second cable 29 on the guiding and monitoring assembly 30, including the pressure size and the angle between the pressure and the vertical direction, so that the controller can monitor the tension of the second cable 29 in real time. In summary, the controller can analyze the data and timely adjust the first towing and rescue winch 10 and the second towing and rescue winch 20 to make the tensions of the first cable 11 and the second cable 29 equal, so as to realize the coordinated operation and improve the service life of the single winch, which has high practicability.

[0057] In some embodiments, the fixed pulley and the guiding and monitoring assembly 30 can adopt the structure as shown in Figure 1 Figure 1 ​The fixed pulley and the guide monitoring component 30 are spaced apart along the width of the tow truck. This structure avoids interference between the first cable 11 and the second cable 29.

[0058] In some embodiments, the hook component 40 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 The hook component 40 is provided with a guide wheel for the first cable 11 to be wound around and guide the first cable 11; the hook is provided with a connecting end for the end of the second cable 29 to be hung.

[0059] Specifically, each end of the hook component 40 can be provided with a mounting part, one of which is connected to the vehicle to be rescued, and the other is used to attach the end of the second cable 29. The guide wheel can act as a movable pulley, which can reduce the tension on the first cable 5 by increasing the moving distance of the first cable 11, thus saving effort.

[0060] In this embodiment, a hook can also be provided at the end of the first cable 11 to be hung on the mounting structure on the vehicle body 50. This technology is prior art and will not be described in detail here. In addition, the tension sensor can be directly installed between the first cable 11 and the hook. The connection method of the tension sensor is prior art and will not be described in detail here.

[0061] In some embodiments, the second towing winch 20 described above may employ, as follows: Figures 2-3 The structure shown. See also Figures 2-3 The second towing winch 20 includes a base 21, a rotating shaft 22, a winding drum 23, a tilting frame 24, a cable management structure 25, and a first encoder 26. The rotating shaft 22 is horizontally rotatably mounted on the base 21 and connected to a self-locking module mounted on the base 21; one end of the rotating shaft 22 is connected to a drive structure; the winding drum 23 is coaxially connected to the rotating shaft 22; the tilting frame 24 is rotatably connected to the rotating shaft 22 and has two outwardly extending arms along the radial direction of the rotating shaft 22; the tilting frame 24 has a curved surface 28 whose axis is collinear with the axis of the rotating shaft 22; the cable management structure 25 is fixed on the two outwardly extending arms and has sliding holes for the second cable 29 to pass through; the first encoder 26 is fixed on the base 21 and corresponds to the curved surface 28, and is used to monitor the tilting angle of the tilting frame 24 relative to the horizontal plane in real time.

[0062] After the second cable 29 passes through the guide monitoring assembly 30 and the second cable 29 is tightened, the second cable 29 between the winding drum 23 and the guide monitoring assembly 30 is arranged in an inclined manner. As for the line arrangement structure 25, the second cable 29 can pull the turnover frame 24 to rotate upward, which can avoid the line arrangement structure 25 from bearing the force from the second cable 29, thereby prolonging the service life of the line arrangement structure 25 and reducing the abrasion of the second cable 29. The first encoder 26 corresponds to the turnover frame 24, and specifically, the power input end of the first encoder 26 is in surface contact with the turnover frame 24, thereby being capable of monitoring the inclination change amount of the second cable 29 between the winding drum 23 and the guide monitoring assembly 30 in real time. Because the diameter of the coil on the winding drum 23 is always changing, the inclination angle of the second cable 29 between the winding drum 23 and the guide monitoring assembly 30 is also always changing, which can ensure real-time monitoring of the angle.

[0063] The via in the line arrangement structure 25 does not affect the straightness of the second cable 29, and therefore, as for the inclination angle of the second cable 29 between the winding drum 23 and the guide monitoring assembly 30, it can be understood as the angle from the state in which the second cable 29 extends horizontally and outward to the working state, and specifically, the angle can be adjusted by the second cable 29 when the first encoder 26 is initially zeroed.

[0064] The base 21 can be fixed to the vehicle body 50 of the towing and rescue vehicle, and the base 21 can be arranged in a “N” shaped structure to facilitate the rotational connection of the rotating shaft 22. The winding drum 23 is located in the cavity in the middle of the base 21. As for the self-locking module on the winch, it is prior art and will not be described here.

[0065] It should be noted that the first towing and rescue winch 10 can have the same structure as the second towing and rescue winch 20, but the first towing and rescue winch 10 does not need to be provided with an encoder.

[0066] In some embodiments, the above-mentioned line arrangement structure 25 can adopt a structure as shown in Figure 2 . Referring to Figure 2 , the line arrangement structure 25 comprises a guide rod 251, a reciprocating screw rod 252, a sliding block 253, and a driving motor 254. The guide rod 251 is arranged in parallel with the rotating shaft 22 and is fixed to the two extending arms; the reciprocating screw rod 252 is arranged in parallel with the guide rod 251 and is rotatably arranged on the two extending arms; the sliding block 253 is slidingly arranged on the guide rod 251 and is screwedly connected with the reciprocating screw rod 252; the sliding hole is located on the sliding block 253; and the driving motor 254 is fixed to the extending arm and is power-connected with the reciprocating screw rod 252.

[0067] The reciprocating screw 252 is driven by the motor 254 to rotate, and then the slider 253 is reciprocated on the guide rod 251 to realize the arrangement of the second cable 29 on the winding drum 23.

[0068] In the embodiment, in order to avoid the sliding friction of the second cable 29 passing through the through hole, at least four rotating rollers are arranged on the slider 253, two of which are arranged in the vertical direction and are arranged on the slider 253 in the horizontal direction, and the other two are arranged in the width direction of the vehicle body 50 and are arranged on the slider 253 in the vertical direction, and the four rotating rollers form a through hole, thereby converting sliding friction into rolling friction.

[0069] In some embodiments, the above-mentioned guide monitoring assembly 30 can adopt the structure as shown in Figure 4 and Figure 5 . Referring to Figure 4 and Figure 5 , the guide monitoring assembly 30 comprises two vertical supports 31, a deflection shaft 32, a second encoder 37, a prism sleeve 33, a hanger 34, a pressure sensor 35 and a wire wheel 36. The two vertical supports 31 are arranged in the width direction of the vehicle body 50 of the towed rescue vehicle. The deflection shaft 32 is arranged horizontally and is rotatably connected to the two vertical supports 31 at both ends. The second encoder 37 is fixedly arranged on one of the vertical supports 31 and is connected to the deflection shaft 32. The prism sleeve 33 is coaxially connected to the deflection shaft 32 and is located between the two vertical supports 31. The hanger 34 is located between the two vertical supports 31 and is slidably connected to the prism sleeve 33 at the top end. The pressure sensor 35 is arranged on the hanger 34 and is in abutment with the prism sleeve 33. The wire wheel 36 is rotatably arranged at the bottom end of the hanger 34 and is arranged in parallel with the deflection shaft 32, and the wire wheel 36 is used for guiding the second cable 29.

[0070] The tension of the second cable 29 is equal everywhere, but the angle between the second cable 29 on both sides of the vertical support 31 and the vertical direction is different, so the resultant force of the second cable 29 on the wire guide wheel 36 is not along the vertical direction, and the resultant force (pressure) gradually changes with the movement of the rescued vehicle. The top of the hanger 34 is connected to the vertical support 31 through the prism sleeve 33 and the deflection shaft 32, and this structure can ensure that the direction of the line connecting the axis of the wire guide wheel 36 and the axis of the deflection shaft 32 is the pressure direction of the second cable 29 on the wire guide wheel 36, and the angles between the second cable 29 on both sides and the line are equal. A second encoder 37 is also provided, and the value monitored by the second encoder 37 is the angle between the line connecting the axis of the wire guide wheel 36 and the axis of the deflection shaft 32 and the vertical direction, which is set as θ1. In addition, the pressure sensor 35 is also always rotating under the action of the prism sleeve 33, so the pressure direction measured by the pressure sensor 35 is exactly the direction of the line connecting the axis of the wire guide wheel 36 and the axis of the deflection shaft 32, and the pressure value is set as F. In addition, the inclination angle θ2 of the second cable 29 between the winding drum 23 and the guide monitoring assembly 30 is set. According to the following formula:

[0071]

[0072] It should be noted that G 绳 is the weight of the second cable 29. The weight of the second cable 29 gradually changes, which can be calculated according to its elongation. Of course, when the pulling force of the first cable 11 and the second cable 29 is greater than 150KN, its weight can be ignored.

[0073] Therefore, through the structure of the guide monitoring assembly 30, the tension of the second cable 29 can be indirectly detected, the monitoring components such as the pressure sensor 35 are located on the towed vehicle, which is more convenient for electrical connection and signal transmission. Through this structure, the pulling force of the first cable 11 and the second cable 29 can be kept consistent, thereby ensuring the cooperative operation of the first tow winch 10 and the second tow winch 20, and the practicability is strong.

[0074] In some embodiments, the hanger 34 described above can adopt the structure as shown in Figure 4 and Figure 5 . Referring to Figure 4 and Figure 5The hanger 34 comprises a top plate 341 and vertical plates 342. The top plate 341 is horizontally arranged above the deflection shaft 32; the vertical plates 342 are provided in two, and the two vertical plates 342 are arranged in the spacing direction of the two vertical supports 31 and the top ends are respectively connected to the two ends of the top plate 341; the bottom ends of the two vertical plates 342 are rotationally connected with the wire wheel 36; the top of each vertical plate 342 is provided with a long strip sliding port for sliding connection of the prism sleeve 33, and the top end of the long strip sliding port extends to the top plate 341.

[0075] The pressure sensor 35 is located between the top plate 341 and the prism sleeve 33.

[0076] The arrangement of the hanger 34 can ensure the sliding connection with the prism sleeve 33, and also ensure the arrangement of the pressure sensor 35, and the structure is simple, easy to manufacture and high in practicability.

[0077] In some embodiments, the prism sleeve 33 can adopt the structure as shown in Figure 4 . Referring to Figure 4 , the cross section of the prism sleeve 33 is rectangular, which can facilitate manufacturing, and also can avoid circumferential sliding between the long strip sliding port, thereby ensuring that the hanger 34 can drive the deflection shaft 32 to rotate synchronously.

[0078] In some embodiments, the first and second tow rescue winches 10 and 20 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the first and second tow rescue winches 10 and 20 also need to be arranged in the width direction of the vehicle body 50 to avoid interference between the first and second cables 11 and 29.

[0079] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
