[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] See also Figure 1-4 A special vehicle for transporting box culverts comprises a vehicle body 1, and a front vehicle 2 is arranged on one side of the vehicle body 1 for driving the vehicle body 1 to move. A placement slot 3 is arranged on the top of the vehicle body 1 for placing the box culvert. A fixed support block 4 is fixedly connected to the side of the placement slot 3 close to the front vehicle 2, and a plurality of driving cylinders 5 are fixedly installed on the side of the placement slot 3 away from the front vehicle 2, and a movable support block 6 is fixedly connected to the output end of each driving cylinder 5. The position of the movable support block 6 can be adjusted by starting the driving cylinder 5, and then the box culverts of different sizes can be supported by cooperating with the fixed support block 4. Side panels 7 are fixedly connected to both sides of the top of the vehicle body 1, and mounting slots 8 are opened in the horizontal direction on the opposite surfaces of the two side panels 7. A fixed clamping mechanism 9 is arranged in the mounting slot 8 to limit and clamp the two sides of the box culvert. A plurality of fixed ring buckles 10 are arranged on the top of the side panels 7 at equal intervals, and the box culvert is fixed by cooperating with the rope.

[0022] Furthermore, the support surfaces of the fixed support block 4 and the movable support block 6 are both installed with sleepers 11, which can play a buffering role when encountering bumps during the transportation of the box culvert to prevent the box culvert from being damaged.

[0023] Furthermore, both sides of the movable support block 6 are fixedly connected to the limit blocks 12, and the inner walls of the placement slot 3 are provided with limit sliding grooves 13 adapted to the limit blocks 12. The movable support block 6 is used to limit the movable support block 6 so that it can only move horizontally, thereby improving the stability of the movable support block 6 when in use.

[0024] Furthermore, a plurality of reinforcing members 14 are fixedly connected between the two side panels 7 and the vehicle body 1 , so as to strengthen and fix the side panels 7 .

[0025] Further, the fixed clamping mechanism 9 includes a bidirectional threaded rod 901 rotatably connected in the mounting groove 8, a driving motor 902 is fixedly installed on the side of the side plate 7 close to the front of the vehicle 2, one end of the bidirectional threaded rod 901 passes through the side plate 7 and is connected to the output end of the driving motor 902, and both ends of the bidirectional threaded rod 901 are threadedly connected with moving blocks 903 adapted to the mounting groove 8, a clamping plate 904 is arranged at intervals on the outer side of the moving block 903, and a support plate 905 is hinged between the clamping plate 904 and the two moving blocks 903. By starting the driving motor 902 to drive the bidirectional threaded rod 901 to rotate, the moving blocks 903 on both sides are driven to move relative to or oppositely. When the moving blocks 903 on both sides move relative to each other, the clamping plate 904 will be driven to approach the box culvert through the cooperation of the support plate 905, and when the moving blocks 903 on both sides move oppositely, the clamping plate 904 will be driven to move away from the box culvert through the cooperation of the support plate 905.

[0026] When in use, first start the driving cylinder 5 to adjust the position of the movable support block 6 according to the size of the culvert, then lift the culvert by the crane and place it in the placement groove 3, support the bottom surface of the culvert by the fixed support block 4 and the movable support block 6, then start the driving motor 902 to drive the bidirectional threaded rod 901 to rotate, and then drive the movable blocks 903 on both sides to move relative to each other. When the movable blocks 903 on both sides move relative to each other, the clamping plate 904 will be driven to approach the culvert through the support plate 905, and the box culvert is limited and clamped by the cooperation of the clamping plates 904 on both sides. Finally, the rope is passed through the fixed ring buckles 10 on both sides to fix the box culvert. After the fixation is completed, the box culvert is transported by the cooperation of the car head 2 and the car body 1.
