The two ends of the long strip connecting plate 22 are respectively installed into the corresponding two receiving grooves 39, and the second connecting hole is aligned with the first connecting hole. The fasteners 23 are inserted through the second connecting hole and the first connecting hole for detachable connection of the two bearing blocks 3; multiple bearing blocks 3 are installed into the mounting groove 12, and multiple bearing blocks 3 in the same auxiliary support device 11 are evenly spaced. Then, the long strip connecting plate 22 is installed between two bearing blocks 3, and the two ends of the long strip connecting plate 22 are respectively installed into the corresponding two receiving grooves 39. Then, the fasteners 23 are inserted through the first connecting hole and the second connecting hole to fix the two ends of the long strip connecting plate 22 to the two bearing blocks 3. The first linear actuator 32 is fixedly connected to a nearby support block 3, thereby driving multiple support blocks 3 to move together within the mounting groove 12. After pushing or pulling the multiple support blocks 3 back to the accurate working position, the fasteners 23 and the elongated connecting plate 22 can be gradually removed. The first connecting hole is set as a screw hole, and the fastener 23 is a bolt; there are multiple first connecting holes on the receiving groove 39 and multiple second connecting holes on the elongated connecting plate 22, and multiple fasteners 23 as well.

[0047] Please see Figure 4 and Figure 5 , Figure 8As a specific embodiment of the heavy-duty vehicle towing and rescue vehicle provided by the present invention, the bearing block 3 has upwardly extending protrusions 24 on both sides, and receiving grooves 39 are formed on the protrusions 24. The depth of the receiving grooves 39 is greater than the sum of the thickness of the long strip connecting plate 22 and the thickness of the fastener 23 protruding above the long strip connecting plate 22. The protrusions 24 can form receiving grooves 39 with a certain depth, so that after the long strip connecting plate 22 is installed into the receiving grooves 39, there is still a large space for installing the fasteners 23. After the fasteners 23 are inserted into the first connecting hole and the second connecting hole, the fasteners 23 located in the area above the long strip connecting plate 22 will not protrude outside the receiving grooves 39, and thus will not interfere with or affect the operation of other external devices.

[0048] Please see Figures 3 to 5 As a specific embodiment of the heavy-duty vehicle towing and rescue vehicle provided by the present invention, three mounting slots 12 are connected to form a U-shaped groove. Multiple reinforcing ribs are provided within each mounting slot 12, and these reinforcing ribs are spaced apart along the length of the U-shaped groove. The two side mounting slots 12 and one end mounting slot 12 are connected to form a single U-shaped groove, increasing the flexibility and effective usable area within the three mounting slots 12, and also increasing the range of movement. Simultaneously, reinforcing ribs are arranged within each mounting slot 12 to ensure that the multiple mounting slots 12 do not affect the strength and load-bearing capacity of the chassis 1 itself.

[0049] Please see Figures 3 to 5 As a specific embodiment of the heavy-duty vehicle towing and rescue vehicle provided by the present invention, a pressure sensor 72 is provided on the movable top plate 71; a control system is also provided on the chassis 1, and the first linear drive mechanism 5, pulling mechanism 6, first lifting mechanism 7, driver 32 and pressure sensor 72 are all electrically connected to the control system; the pressure sensor 72 can detect the supporting effect of the movable top plate 71 on the base arm 81, so as to maximize the force of the auxiliary support device 11 on the base arm 81, and ensure that the action on the base arm 81 is more stable and reliable. The control system is provided, and the control system is connected to the first linear drive mechanism 5, pulling mechanism 6, first lifting mechanism 7, driver 32 and pressure sensor 72, so the first linear drive mechanism 5, pulling mechanism 6, first lifting mechanism 7 and driver 32 can be started or stopped by means of the control system. The first linear drive mechanism 5, pulling mechanism 6 and first lifting mechanism 7 are all hydraulic cylinders, while the driver 32 is a hydraulic motor.

[0050] Please see Figures 3 to 5 , Figure 9As a specific embodiment of the heavy-duty vehicle towing and rescue vehicle provided by the present invention, the movable top plate 71 is provided with a first mounting hole 73 and a locking connector 74. The lower end face of the base arm 81 of the towing device 8 is provided with a second mounting hole corresponding to the first mounting hole 73 on both sides. The movable top plate 71 and the base arm 81 are fixedly connected by the locking connector passing through the first mounting hole 73 and the second mounting hole. When towing and rescuing a vehicle that is too heavy, when the movable top plate 71 on one side acts on the lower end face of the base arm 81, the movable top plate 71 on the other side can be fixed on the lower end face of the base arm 81 by the locking connector 74. At the same time, the first lifting mechanism 7 at that side position is activated and moves downward. The movable top plate 71 generates a downward force on that side position of the base arm 81 to ensure that the base arm 81 works in a balanced and stable manner.

[0051] Please see Figures 3 to 6 , Figure 10 As a specific embodiment of the heavy-duty vehicle towing and rescue vehicle provided by the present invention, the support plate 4 has an inwardly recessed push-pull groove 41 on one end face away from the pulling mechanism 6, and a sliding groove 42 communicating with the push-pull groove 41 on the upper end face; an extension plate 43 and a second linear drive mechanism 44 connected to the extension plate 43 are provided in the push-pull groove 41; a first lifting mechanism 7 is installed on the extension plate 43; the extension plate 43 is installed in the support plate 4, and the extension plate 43 can be in the push-pull groove 41, and the second linear drive mechanism 44 is connected to the extension plate 43. The first lifting mechanism 7 is installed on the extension plate 43, and the lower end of the first lifting mechanism 7 is located in the sliding groove 42. During operation, the second linear drive mechanism 44 is activated to move the extension plate 43 within the push-pull groove 41. Utilizing the clearance capability of the sliding groove 42, the first lifting mechanism 7 can move along with the extension plate 43. This effectively alters the docking position of the first lifting mechanism 7 and the movable top plate 71 on the base arm 81, increasing the effective range of the first lifting mechanism 7 and allowing the movable top plate 71 to act further outwards from bottom to top on the base arm 81, resulting in better support. The second linear drive mechanism 44 can be a hydraulic cylinder.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
