[0035] It includes a supporting device, and the supporting device includes a lifting plate 27 and a support plate 32 that can support the flat plate 11. The lifting plate 27 and the support plate 32 are also both arranged at the rear side position of the wrecker 10.

[0036] It should be noted that: the wrecker 10 and the flat plate 11 have both been disclosed in the prior art and will not be elaborated here.

[0037] During specific use, the sliding device can control the flat plate 11 to move and rotate conveniently through the first guide plate 14, the first motor 19, and the second motor 23, so as to perform obstacle clearing operations on the flat plate 11. The supporting device can support the flat plate 11 through the lifting plate 27 and the supporting plate 32, preventing the flat plate 11 from bending due to gravity.

[0038] In summary, by setting the sliding device and the supporting device, the flat plate 11 can be moved and rotated conveniently and quickly through the sliding device to perform obstacle clearing operations. The supporting device can support the bottom of the flat plate 11 to prevent the flat plate 11 from bending due to gravity. Compared with the prior art, it has the characteristics of convenient use and simple structure.

[0039] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, a first limit groove 12 is provided at each of the left and right ends on the top wall surface at the rear side of the wrecker 10. The number of the first guide plates 14 is two, and the two first guide plates 14 are respectively fixedly installed at the left and right ends of the bottom wall surface of the flat plate 11. The front and rear side walls of the two first guide plates 14 are in a hollow state.

[0040] A first fixing plate 16 is fixedly installed at each of the left and right ends of the rear wall surface of the wrecker 10. A rotating plate 20 is rotatably installed on the side wall surface of each of the two first fixing plates 16 close to each other. A third fixing plate 18 is fixedly installed on the rear wall surface of the wrecker 10 on the side where the two rotating plates 20 are close to each other. The number of the first motors 19 is two, and the two first motors 19 are respectively fixedly installed on the front side wall surfaces of the rotating plates 20. A first bolt 15 is fixedly installed at the output end of each of the two first motors 19. The two first fixing plates 16 are respectively in threaded connection with the cavities of the two corresponding first guide plates 14.

[0041] A second fixing plate 17 is also fixedly installed on the rear wall surface of the wrecker 10. The number of the second motors 23 is two, and the two second motors 23 are respectively fixedly installed on the left and right side wall surfaces of the two second fixing plates 17. A second bolt 21 is fixedly installed at the output end of each of the two second motors 23. The two second bolts 21 penetrate through the corresponding third fixing plates 18. One end of each of the two third fixing plates 18 away from each other is respectively fixedly connected to the corresponding rotating plate 20. The first motor 19 and the second motor 23 are both electrically connected to the power supply and the switch by electrical signals.

[0042] During specific use, when the output end of the first motor 19 rotates, it can drive the first bolt 15 of the flat plate 1 to rotate. The rotation of the first bolt 15 can drive the first guide plate 14 that is threadedly connected to the first bolt 15 to move back and forth. Due to the limitation of the first limit groove 12, the first guide plate 14 cannot rotate and will move back and forth under the drive of the thread. When the two first guide plates 14 move back and forth, they can drive the flat plate 11 to move. When the output end of the second motor 23 rotates, it can drive the second bolt 21 to rotate. The rotation of the second bolt 21 can drive the rotating plate 20 to rotate. The rotation of the rotating plate 20 can drive the first motor 19 to rotate. The rotation of the first motor 19 can drive the first bolt 15 to rotate. The rotation of the first bolt 15 can drive the first guide plate 14 to rotate. The rotation of the first guide plate 14 can drive the flat plate 11 to rotate, thereby controlling the movement and rotation of the flat plate 11. Both of the two first fixing plates 16 can play a role in limiting the rotating plate 20, and the third fixing plate 18 can play a role in supporting the second bolt 21 to bear the gravity of the flat plate 11.

[0043] In summary, by setting the flat plate 11, the first limit groove 12, the first guide plate 14, the first bolt 15, the first fixing plate 16, the second fixing plate 17, the third fixing plate 18, the first motor 19, the rotating plate 20, the second bolt 21, and the second motor 23, the rotation of the output end of the first motor 19 can drive the flat plate 11 to move, and the rotation of the output end of the second motor 23 can drive the flat plate 11 to rotate. It is convenient to use and has a simple structure.

[0044] As Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, a second limit groove 13 is provided on the rear side wall surface of the roadblock removal vehicle 10 at a position below the second fixing plate 17. A second guide plate 24 is movably installed in the cavity of the second limit groove 13. A plurality of racks 26 are fixedly installed at equal intervals at the left and right ends of the top wall surface of the second guide plate 24. A spur gear 22 is fixedly installed on the side wall of each of the two second bolts 21, and the two spur gears 22 are respectively meshed with the corresponding racks 26.

[0045] A fifth fixing plate 25 is fixedly installed on the top wall surface of the second guide plate 24. The left and right side wall surfaces of the fifth fixing plate 25 are both in a hollowed-out state. The lifting plate 27 is movably installed in the cavity of the fifth fixing plate 25. The support plate 32 is arranged above the lifting plate 27. At both ends of the bottom wall surface of the support plate 32, a rotating block 33 is fixedly installed. On the side wall surfaces of the two rotating blocks 33 close to each other, they are respectively rotatably connected to the left and right side wall surfaces of the lifting plate 27. On the bottom wall surface of the lifting plate 27, two strong springs 28 are fixedly installed. One end of each of the two strong springs 28 away from the lifting plate 27 is fixedly connected to the bottom wall surface of the fifth fixing plate 25.

[0046] On the left and right side wall surfaces of the lifting plate 27, a rotating rod 34 is fixedly installed. The two rotating rods 34 both penetrate through the hollow parts on the left and right sides of the fifth fixing plate 25. On the top wall surface of the second guide plate 24, two reset rods 29 are arranged. The rear ends of the two reset rods 29 are respectively sleeved on the two rotating rods 34. On the top wall surface of the second guide plate 24, two clamping grooves 31 are also opened. On the left and right side wall surfaces of one end of the reset rod 29 away from the rotating rod 34, a clamping block 30 is fixedly installed. The clamping grooves 31 correspond to the shapes of the clamping blocks 30. The two clamping blocks 30 are respectively movably connected to the corresponding clamping grooves 31. The top wall surface of the reset rod 29 is in contact with the bottom wall surface of the second fixing plate 17.

[0047] During specific use, when the second bolt 21 rotates, it can also drive the spur gear 22 to rotate. The rotation of the spur gear 22 can drive the second guide plate 24 to move back and forth through meshing with the rack 26. The movement of the second guide plate 24 can drive the fifth fixing plate 25 to move. The movement of the fifth fixing plate 25 can drive the lifting plate 27 to move. When moving a certain distance, the top wall surface of the reset rod 29 will separate from the second fixing plate 17. The strong spring 28 can push the lifting plate 27 upward through its acting force. The movement of the lifting plate 27 can drive the support plate 32 to move, so that the top wall surface of the support plate 32 abuts against the bottom wall surface of the flat plate 11, thereby playing a supporting role for the flat plate 11. Through the rotational connection between the rotating block 33 and the lifting plate 27, the support plate 32 can rotate, so that the support plate 32 can cope with flat plates 11 in different inclined states. When the flat plate 11 is reset, the two second bolts 21 can rotate in the reverse direction, so that the second guide plate 24 is reset, and then the lifting plate 27 is driven to reset. During resetting, the top wall surface of the reset rod 29 will contact the bottom wall surface of the second fixing plate 17, so as to press the reset rod 29 downward. The downward pressing of the reset rod 29 can drive 34 and then drive the lifting plate 27 to press downward, so that the lifting plate 27 is reset to avoid conflicting with the position of the flat plate 11. Both the clamping block 30 and the clamping groove 31 can play a role in limiting the reset rod 29.

[0048] In summary, by providing the second motor 23, spur gear 22, second bolt 21, second guide plate 24, fifth fixing plate 25, rack 26, lifting plate 27, strong spring 28, reset rod 29, latch 30, card slot 31 and support plate 32, when the second bolt 21 drives the flat plate 11 to rotate, the support plate 32 can be driven to support the bottom wall surface of the flat plate 11. During reset, the support plate 32 can automatically reset, which is convenient to use and has a simple structure.
