As shown in fig. 4 and fig. 7 and 8, a schematic structural view of a tray lifting/lowering mechanism 20 in a van vehicle and a van semi-trailer capable of automatically loading and unloading a tray-containing cargo is provided according to a preferred embodiment of the present invention. The pallet lifting and traveling mechanism 20 includes a lifting and lowering support rod 200, a lifting and lowering push-pull rod 201, a moving push-pull rod 202, a gutter raceway 203, a lifting cylinder 204, a reciprocating cylinder 205, and a double hinge plate 206.

The cross section of the lifting support rod 200 is a groove with a downward opening, and the inner plane of the upper groove bottom is uniformly provided with lifting oblique blocks 2000. The elevation ramp 2000 has a ramp with a normal 2001 pointing in a forward and downward direction. The height of the lifting inclined block 2000 is less than the height of two vertical edges of the lifting support rod 200. The inclination degree of the slope of the elevation slope piece 2000 is determined by the maximum weight of the pallet container goods loaded by the vehicle, and the inclination degree of the elevation slope piece 2000 is smaller as the maximum weight of the loaded pallet container goods is larger; conversely, the greater the inclination of the elevation swash block 2000.

The cross section of the lifting push-pull rod 201 is a groove with an upward opening, and the lifting push-pull rod is arranged in the moving push-pull rod 202. The lifting push-pull rod 201 is housed in the groove of the lifting bracket rod 200 together with the moving push-pull rod 202. Lifting rollers 2012 are uniformly arranged at the upper part in the groove of the lifting push-pull rod 201, and the number of the lifting rollers 2012 is equal to that of the lifting oblique blocks 2000. The highest point of the lifting roller 2012 is in the same plane with the upper plane of the lifting push-pull rod 201. The lifter roller 2012 is in one-to-one relationship with the lifter block 2000, i.e., at the initial position, the lifter roller 2012 is in contact with the lower end of the lifter block 2000. A lifting moving roller 2013 is further arranged at the lower part in the groove of the lifting push-pull rod 201, and the lifting moving roller 2013 penetrates through a third rectangular hole 2010 arranged on the bottom plane of the lifting push-pull rod 201 to be in contact with the upper plane of the bottom of the moving push-pull rod 202. The lifting oil cylinder 204 is arranged between the lifting support rod 200 and the moving push-pull rod 202, the fixed end of the lifting oil cylinder 204 is fixedly connected with the moving push-pull rod 202, and the telescopic end of the lifting oil cylinder 204 is fixedly connected with the lifting push-pull rod 201. Under the driving of the lifting oil cylinder 204, the lifting push-pull rod 201 makes longitudinal reciprocating movement between the lifting support rod 200 and the moving push-pull rod 202, and under the interaction of the lifting roller 2012 and the lifting oblique block 2000, the lifting support rod 200 is lifted or lowered in the longitudinal reciprocating movement process.

The cross section of the moving push-pull rod 202 is a groove with an upward opening, and the moving push-pull rod 202 supports the lifting push-pull rod 201 in the groove. Meanwhile, the push-pull rod 202 is moved to be positioned in a groove with a downward opening of the lifting support rod 200, and the lifting support rod 200 is supported upwards or supported through the lifting moving roller 2013, the lifting push-pull rod 201, the lifting roller 2012 and the lifting oblique block 2000. The reciprocating roller 2021 is arranged at the lower part in the moving push-pull rod 202, and the reciprocating roller 2021 passes through a first rectangular hole 2020 formed on the bottom plane of the moving push-pull rod 202 to contact with the top plane of the bottom groove raceway 203. Since the moving push-pull rod 202 supports the lifting push-pull rod 201 in the groove and the gap between the upper plane of the groove bottom of the moving push-pull rod 202 and the lower plane of the groove bottom of the lifting push-pull rod 201 is small, a second rectangular hole 2011 needs to be formed in the groove bottom of the lifting push-pull rod 201 to provide a space for installing the reciprocating roller 2021 and a space for moving the lifting push-pull rod 201.

The cross section of the bottom groove roller path 203 is a groove with an upward opening, and the width of the groove opening is the same as that of the downward opening of the lifting support rod 200. The height of the vertical sides of the bottom groove raceway 203 is preferably set so as not to interfere with the lowering of the lifter pin 200. The lower plane of the bottom groove raceway 203 is flatly and fixedly connected with the upper plane of the bottom of the first groove 1. The reciprocating oil cylinder 205 is arranged in the moving push-pull rod 202, the fixed end of the reciprocating oil cylinder 205 is fixedly connected with the front end plane of the bottom plate of the van body, and the telescopic end of the reciprocating oil cylinder 205 is fixedly connected with the moving push-pull rod 202. Since the upper plane of the bottom groove raceway 203 contacts the reciprocating roller 2021 mounted on the moving push-pull rod 202, the lifting push-pull rod 201 and the lifting support rod 200 supported by the moving push-pull rod 202 can reciprocate on the bottom groove raceway 203 by the reciprocating cylinder 205.

The stroke of the lift cylinder 204 is determined by the maximum weight of the pallet container loaded by the vehicle, and when the maximum weight of the loaded pallet container is larger, the stroke of the lift cylinder 204 is larger; whereas the smaller the stroke of the lift cylinder 204. When the lift cylinder 204 pushes, the lift push-pull rod 201 moves to the rear of the car, and at this time, the lift bracket rod 200 rises upward under the interaction of the lift roller 2012 and the lift ramp 2000. When the lifting cylinder 204 is pulled, the lifting push-pull rod 201 moves towards the front part of the carriage, and at this time, under the interaction of the lifting roller 2012 and the lifting oblique block 2000, the lifting support rod 200 falls back downwards until the upper plane of the lifting support rod 200 is not higher than the upper plane of the first groove 1.

The stroke of the reciprocating oil cylinder 205 can be selected to be not less than the length of the containerized cargo pallet along the longitudinal direction of the carriage, and other stroke lengths can be selected. When the reciprocating cylinder 205 performs pushing or pulling action, the moving push-pull rod 202 on the bottom groove raceway 203 reciprocates in the vehicle compartment together with the lifting support rod 200, the lifting push-pull rod 201, and the lifting cylinder 204 supported by the moving push-pull rod 202, and the distance of each movement is equal to the stroke of the reciprocating cylinder 205.

As shown in fig. 5, for the purpose of the present invention, a rear end structure diagram of a tray lifting/lowering mechanism 20 of a van vehicle and a van semi-trailer capable of automatically loading and unloading the tray containerized goods is provided. The rear end of the lifting pin 200 is connected to a double hinge plate 206, and the double hinge plate 206 includes an upper plate 2060, a middle plate 2061, a lower plate 2062, an upper shaft 2063, and a lower shaft 2064. The upper plate 2060 is horizontally fixed to the rear end of the lifting pin 200. The lower plate 2062 is vertically fixed to the rear end of the movable push-pull rod 202. The middle plate 2061 is hinged at one end to the upper plate 2060 via an upper shaft 2063 and at the other end to the lower plate 2062 via a lower shaft 2064. The length of the middle plate 2061 is related to the height of the lift pin 200, and when the lift pin 200 is raised or lowered, the lift pin 200 moves within a certain horizontal range under the restriction of the double hinge plate 206. By providing the double hinge plate 206, the stability of the pallet containerized goods during the loading and unloading operation can be improved.
