Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-3:
a turning protection device of a semitrailer is installed on two sides of a frame 1 of the semitrailer and comprises a protection plate 2, a plurality of first connecting rods 3 which are used for connecting the protection plate 2 with the frame 1 and enabling the protection plate 2 to be close to or far away from the frame 1, and a driving mechanism 4 which drives the protection plate 2 to be close to or far away from the frame 1, wherein the driving mechanism 4 can adopt a motor and a speed reducer, the motor drives the speed reducer to rotate, and the speed reducer drives the first connecting rods 3 to rotate;
meanwhile, a hydraulic oil cylinder can be adopted, specifically, the driving mechanism 4 comprises a hydraulic telescopic oil cylinder 10, the cylinder end of the hydraulic telescopic oil cylinder 10 is hinged to the frame 1, the piston rod end on the hydraulic telescopic oil cylinder is hinged to one first connecting rod 3, the hydraulic telescopic oil cylinder 10 drives one first connecting rod 3 to rotate, the first connecting rod 3 drives the other first connecting rods 3 to rotate through the second connecting rod 5, meanwhile, the second connecting rod 5 moves under the action of all the first connecting rods 3, when the second connecting rod 5 is close to the frame 1, the piston rod of the hydraulic telescopic oil cylinder 10 is in an extending state, the hydraulic telescopic oil cylinder 10 can be electrically connected with a steering system of a tractor, when the semitrailer turns, the piston rod of the hydraulic telescopic oil cylinder 10 retracts, and when the semitrailer moves straightly, the piston rod of the hydraulic telescopic oil cylinder 10 extends.
The protection plate 2 is used for blocking and warning pedestrians or people riding bicycles and the like, so that the pedestrians or people riding bicycles are prevented from approaching a semi-trailer turning, the protection plate 2 is parallel to the side end face of the frame 1, the protection plate 2 comprises a second connecting rod 5 and a baffle plate 6, the second connecting rod 5 is hinged to the first connecting rod 3, one end of the first connecting rod 3 is hinged to the side end face of the frame 1, the other end of the first connecting rod 3 is hinged to the second connecting rod 5, the axial direction of a hinged shaft of the first connecting rod 3 is a vertical direction, all the first connecting rods 3 act synchronously, the first connecting rod 3 rotates on the frame 1 to drive the second connecting rod 5 to approach or leave away from the frame 1, wherein the length of the first connecting rod 3 can ensure that the protection plate 2 moves to the edge of a dangerous area when the semi-trailer turns, the upper end of the baffle plate 6 is hinged to the second connecting rod 5, and, the baffle 6 can rotate along the second connecting rod 5, so that the maintenance at the wheel position of the semitrailer is convenient,
