[0022] Example:

[0023] Reference Figure 1-3 As shown, this embodiment is a lifting and reversing mechanism for a cargo platform, comprising a cargo platform 1, a transverse conveying structure 2 arranged on the cargo platform 1, and a longitudinal conveying structure 3 arranged on the cargo platform 1 and adjustable in height relative to the transverse conveying structure 2; at least one lifting and reversing component 4 for driving the longitudinal conveying structure 3 to rise and fall is arranged on the cargo platform 1, a roller 31 is arranged on the longitudinal conveying structure 3, the lifting and reversing component 4 comprises at least one cam seat 41 driven to move horizontally, and the cam seat 41 is provided with an inclined surface 42 for cooperating with the support roller 31 and guiding its rising and falling.

[0024] The cargo platform 1 includes a cargo platform 11, a side wall 12 disposed on the top of the cargo platform 11, and a side rib 13 disposed on the top of the cargo platform 11 and arranged vertically relative to the side wall 12; the side walls of the side wall 12 and the side rib 13 are respectively provided with pulleys 14 for guiding the cargo. An accommodating space is provided inside the cargo platform 11, and a transverse conveying structure 2 and a longitudinal conveying structure 3 are provided in the accommodating space. The cargo enters the transverse conveying structure 2 from the side of the cargo platform 11, and by adjusting the height of the longitudinal conveying structure 3, the cargo is transferred from the transverse conveying structure 2 to the longitudinal conveying structure 3, thereby realizing the reversing transfer process.

[0025] The transverse conveying structure 2 includes a set of transverse fixed frames 21 arranged at intervals, and a plurality of transverse rollers 22 arranged transversely in the transverse fixed frames 21; the plurality of transverse rollers 22 are arranged to rotate in the same direction, and the adjacent transverse rollers 22 are interconnected by chains, and a transverse motor 23 is arranged between a set of transverse fixed frames 21 to coaxially drive the rotation of the plurality of transverse rollers 22 arranged transversely in two rows. The transverse motor 23 drives the linkage shaft to rotate, and the two ends of the linkage shaft extend to the corresponding two rows of transverse rollers 22 respectively, and the linkage shaft is interconnected with two adjacent transverse rollers 22 by chains, thereby providing power for the plurality of transverse rollers 22.

[0026] The longitudinal conveying structure 3 includes two cross beams 32 arranged at intervals, longitudinal fixing frames 33 arranged on both sides of the cross beams 32, and a plurality of longitudinal rollers 34 arranged longitudinally in the longitudinal fixing frames 33; the plurality of longitudinal rollers 34 are arranged to rotate in the same direction, and the interconnection driving mode of the plurality of longitudinal rollers 34 is the same as the interconnection driving mode of the plurality of transverse rollers 22, except that the plurality of transverse rollers 22 arranged in two rows are driven by a transverse motor 23, and the plurality of longitudinal rollers 34 arranged in two rows are driven by two longitudinal motors 35 respectively. The two longitudinal motors 35 provide power for the plurality of longitudinal rollers 34 in two rows respectively.

[0027] Two lifting and reversing assemblies 4 are respectively arranged at the two ends of the cargo platform 1 and are arranged near the cross beam 32. A set of rollers 31 are installed at intervals on each cross beam 32. The lifting and reversing assembly 4 includes a fixed seat 43 installed on the cargo platform 1, a reduction motor and a ball screw 44 installed on the fixed seat 43, a cam seat 41 installed on the ball screw nut, and another cam seat 41 connected to the cam seat 41 through a thrust rod 45; the two cam seats 41 are located in the same straight line direction and are consistent with the conveying direction of the lateral conveying mechanism 2. The position height of the lifting and reversing assembly 4 is consistent with that of the lateral conveying structure 2.

[0028] The end of the cargo platform 1 is located on the side wall of the accommodating space and is provided with a slide rail 15 that matches the cam seat 41. The two cam seats 41 are driven by the ball screw 44 to move horizontally in the same direction. The two rollers 31 on each crossbeam 32 are respectively slidably abutted against the corresponding inclined surfaces 42 of the two cam seats 41. When the inclined surface 42 of the cam seat 41 moves to the bottom of the roller 31 at a high position, the roller 31 and the crossbeam 32 are lifted, and then the longitudinal conveying structure 3 is raised relative to the transverse conveying structure 2; when the inclined surface 42 of the cam seat 41 moves to the bottom of the roller 31 at a low position, the roller 31 and the crossbeam 32 are lowered, and then the longitudinal conveying structure 3 is flush with or lower than the transverse conveying structure 2. After the goods initially enter the cargo platform 1, they are positioned on the transverse conveying structure 2, and the lifting and reversing assembly 4 drives the longitudinal conveying structure 3 to lift, lift the goods away from the transverse conveying structure 2, and the goods continue to be transported along the longitudinal conveying structure 3.

[0029] When this embodiment is applied, the goods are positioned on the transverse conveying structure 2, and the cam seat 41 of the lifting and reversing assembly 4 is driven to move horizontally, thereby pushing the roller 31 and the crossbeam 32 to lift, and the overall longitudinal conveying structure 3 receives the goods from the transverse conveying structure 2, and the goods are reversingly conveyed at right angles.

[0030] In the present embodiment, a lifting and reversing component 4 is arranged in the storage space inside the cargo platform 1, and the lifting and reversing component 4 cooperates with the longitudinal conveying structure 3 to realize height adjustment. The inclined surface 42 of the cam seat 41 of the lifting and reversing component 4 slides with the roller 31 of the longitudinal conveying structure 3, and the driving direction of the cam seat 41 is consistent with the conveying direction of the transverse conveying structure 2, which greatly reduces the occupied space of the lifting and reversing component 4, and the spatial arrangement of the transverse conveying structure 2 and the longitudinal conveying structure 3 is more reasonable and reliable, thereby improving the applicability of cargo transportation.
