[0104] In the embodiment of the utility model, when the wheels of the faulty vehicle are locked, the locking member 42 can be switched to be separated from the roller 41, and the faulty vehicle can be brought to the bottom plate 11 by the rolling of the roller 41. When the wheels of the faulty vehicle are not locked, the locking member 42 can be switched to be separated from the roller 41, and the traction mechanism 3 can pull the faulty vehicle and drag the faulty vehicle to the bottom plate 11.

[0105] Optionally, the roller 41 may be provided with a through hole 411 and a locking hole 412 arranged around the through hole 411, and the axial directions of the through hole 411, the locking hole 412 and the roller 41 are all parallel to the first direction; the locking member 42 includes a limit plate 421 and a rotating shaft 423 and a locking pin 422 connected to the same side of the limit plate 421, the locking pin 422 is connected to the limit plate 421 through an elastic member, the locking pin 422 is detachably connected to the locking hole 412, the rotating shaft 423 passes through the through hole 411 along the first direction, and one side of the limit plate 421 is in contact with the bottom plate 11.

[0106] In the embodiment of the utility model, since one side of the limit plate 421 is in contact with the bottom plate 11, the limit plate 421 can limit the rolling of the roller 41 through the locking pin 422 when the locking pin 422 is inserted into the locking hole 412; when the locking pin 422 is pulled out of the locking hole 412, the roller 41 can roll freely again. The rotation shaft 423 can pass through the through hole 411, so that the roller 41 can rotate in place around the rotation shaft 423.

[0107] Specifically, the number of the locking pin 422 may include at least one, such as Figure 2 Only the case where there are two locking pins 422 is illustrated. In other cases, there may be one or three locking pins.

[0108] Specifically, the locking holes 412 may be evenly spaced around the circumference of the through hole 411 , so that the locking pin 422 can be locked with any one of the locking holes 412 .

[0109] Specifically, the locking pin 422 is connected to the limit plate 421 through an elastic member, and the spring is compressed to facilitate the locking pin 422 to be pulled out of the locking hole 412. The elastic member can be a tension spring or a compression spring, etc. For example, the elastic member can be compressed by operating the joystick on the road fault vehicle, and then when the external force causes the roller 41 to rotate slightly, the elastic member can push the locking pin 422 into the locking hole 412. By operating the joystick, the elastic member is stretched, and the elastic member can drive the locking pin 422 to be pulled out of the locking hole 412.

[0110] Specifically, the side of the limiting plate 421 facing the bottom plate 11 can be in contact with the bottom plate 11, so that the limiting plate 421 cannot rotate relative to the bottom plate 11. The limiting plate 421 can be a polygonal plate or a semicircular plate, such as Figure 2 , only illustrates a case where the limit plate 421 is a rectangular plate, and other cases can refer to the settings.

[0111] Specifically, the limiting plate 421 can be fixedly connected to the bottom plate 11, or the limiting plate 421 can be limited to be movably connected to the bottom plate 11 only along the first direction, so that the limiting plate 421 moves close to the roller 41, which is convenient for inserting the locking pin 422 into the locking hole 412; the limiting plate 421 moves away from the roller 41, which is convenient for pulling the locking pin 422 out of the locking hole 412. In particular, no matter whether the locking pin 422 is inserted into or pulled out of the locking hole 412, the rotating shaft 423 can pass through the through hole 411, so that the roller 41 can only rotate in situ around the rotating shaft 423.

[0112] Optionally, the limiting plate 421 may be fixedly connected to the bottom plate 11 , and the rotating shaft 423 and the roller 41 may be connected via a bearing 424 to further improve the rolling reliability of the roller 41 .

[0113] Specifically, the material of the rotating shaft 423 can be steel or other metal materials to have a strong structural strength.

[0114] Specifically, one roller 41 can form a rolling structure, and a group of locking pins 422 and a rotating shaft 423 can be arranged corresponding to one roller 41. One limiting plate 421 can be connected to one group of locking pins 422 and a rotating shaft 423, or one limiting plate 421 can also be connected to multiple groups of locking pins 422 and a rotating shaft 423 at the same time, which is not specifically limited in the embodiment of the utility model.

[0115] Optionally, one end of the roller 41 can cooperate with the locking member 42, and the other end can be rotatably connected to the shaft, and the shaft can be fixedly connected to the base plate 11 to improve the reliability of the rotation of the roller 41. Moreover, the shaft can also be used to provide support for the roller 41.

[0116] Optionally, the traction mechanism 3 may include a traction motor 31, a traction rope 32 and a fixed pulley 33; the traction motor 31 and the fixed pulley 33 are both connected to the vehicle body, and the fixed pulley 33 is arranged in the vehicle compartment 1; one end of the traction rope 32 is connected to the traction motor 31, and the other end of the traction rope 32 passes through the fixed pulley 33 for connecting to the faulty vehicle.

[0117] In an embodiment of the utility model, the traction motor 31 applies pulling force to the faulty vehicle through the traction rope 32, and the fixed pulley 33 can be located between the traction motor 31 and the faulty vehicle. Changing the direction of the force can improve the reliability and convenience of towing the faulty vehicle into the carriage 1.

[0118] Specifically, the traction motor 31 can be arranged at an upper position of the carriage 1 to prevent the traction motor 31 from being soaked in water and from fire shock caused by a fire or re-ignition of a faulty vehicle. The traction motor 31 can be designed to be waterproof and high temperature resistant.

[0119] Specifically, the fixed pulley 33 can be arranged below the traction motor 31 to stabilize the pulling direction of the traction rope 32. The fixed pulley 33 with the sensor can be designed to be waterproof and high temperature resistant.

[0120] Specifically, the other end of the traction rope 32 may be provided with a traction hook 34 so that the end of the traction rope 32 can hook and lock the trailer hook of the broken-down vehicle.

[0121] Optionally, the road tow truck further includes an alarm, a sensor may be provided on the fixed pulley 33, and the vehicle body may include a cockpit; the sensor may be connected to the alarm, and the alarm may be triggered when the sensor detects that the pulling force is greater than a preset value.

[0122] In an embodiment of the utility model, when the wheels of the broken-down vehicle are locked, the traction rope 32 is connected to the broken-down vehicle, and the traction motor 31 drives the traction rope 32 to pull the broken-down vehicle. When the sensor detects that the pulling force is greater than a preset value, the alarm of the road tow truck can sound an alarm, and then the driver in the cockpit can drive the road tow truck to reverse, and then use the rolling of the roller 41 to bring the broken-down vehicle to the bottom plate 11. In this process, the sliding between the broken-down vehicle and the tail plate 14 or the bottom plate 11 can be converted into rolling, which can further improve the convenience of the towing vehicle.

[0123] For example, the conditions for using the road tow truck for towing include:

[0124] The first method is that the wheels of the faulty vehicle are locked, and the road tow truck lowers the tail plate 14 and the side plate 12; the tail plate 14 is retracted as far as possible to the front wheel of the faulty vehicle; the traction hook 34 at the end of the traction rope 32 is used to hook and lock the trailer hook of the faulty vehicle; the locking pin 422 is pulled out of the locking hole 412, so that the roller 41 can roll. The traction motor 31 is started, and the traction rope 32 generates a pulling force on the faulty vehicle. When the sensor on the fixed pulley 33 detects that the pulling force is greater than the preset value, the alarm is triggered, and the driver can drive the road tow truck to reverse, so that the traction motor 31 does not need to directly drag the faulty vehicle, and the road tow truck can be reversed. Then, the tail plate 14 and the roller 41 on the bottom plate 11 bring the faulty vehicle to the bottom plate 11, and the faulty vehicle rolls relative to the tail plate 14 and the bottom plate 11 respectively, wherein the pulling of the traction motor 31 and the reverse of the road tow truck are performed synchronously until the rear wheels of the faulty vehicle fall on the bottom plate 11 and the reverse is stopped.

[0125] The second method is that the wheels of the faulty vehicle are locked, and the road tow truck lowers the tail plate 14 and the side plate 12; the tail plate 14 is moved back as far as possible to the front wheel of the faulty vehicle; the traction hook 34 at the end of the traction rope 32 is used to hook and lock the trailer hook of the faulty vehicle; the locking pin 422 is pulled out of the locking hole 412, so that the roller 41 can roll. The traction motor 31 is started, and the traction rope 32 generates a pulling force on the faulty vehicle, and then the tail plate 14 and the roller 41 on the bottom plate 11 bring the faulty vehicle to the bottom plate 11, and the faulty vehicle rolls relative to the tail plate 14 and the bottom plate 11 respectively until the rear wheels of the faulty vehicle fall on the bottom plate 11, and the reverse is stopped.

[0126] The third method is that the wheels of the faulty vehicle are not locked, but are locked. The road tow truck lowers the tail plate 14 and the side plate 12; the traction hook 34 at the end of the traction rope 32 is used to hook and lock the trailer hook of the faulty vehicle; the locking pin 422 is inserted into the locking hole 412 to stop the roller 41 from rolling. The traction motor 31 is started, and the traction rope 32 generates a pulling force on the faulty vehicle, pulling the faulty vehicle onto the bottom plate 11 until the rear wheels of the faulty vehicle fall on the bottom plate 11, and the traction motor 31 is turned off.

[0127] The road tow truck described in the embodiment of the utility model has at least the following advantages:

[0128] In the embodiment of the utility model, the carriage can be switched to the open state first, and then the traction mechanism can be used to pull the faulty vehicle to the carriage, and then the carriage can be switched to the closed state. When it is predicted that the faulty vehicle has a risk of fire, the fire extinguishing mechanism can be used to extinguish the fire of the faulty vehicle in the carriage, so as to prevent the fire. When the faulty vehicle has caught fire, the road faulty vehicle can be driven to the faulty vehicle first, and the fire of the faulty vehicle can be extinguished by the fire extinguishing mechanism, which can play the role of a temporary fire truck. Afterwards, after the faulty vehicle is pulled to the carriage, the carriage is switched to the closed state, and the fire extinguishing treatment of the faulty vehicle in the carriage can continue to be performed, so as to prevent the fire from re-igniting. Therefore, the road tow truck in the utility model can ensure that the faulty vehicle is safely towed to the vehicle scrapping site, avoid secondary disasters caused by the faulty vehicle during the towing process, and avoid the loss of personal property and life safety.
