When the driving assembly acts on the supporting assembly 84 to reduce the included angle between the first supporting rod 841 and the second supporting rod 842, the height of the supporting assembly 84 is increased, so as to drive the supporting seat 82 to ascend relative to the base 81, and further lift the supporting part of the piggyback car upwards to a preset height (original position), that is, the supporting part can be rotationally driven by the rotational driving part, after the loading and unloading of the supporting part are completed, the rotational driving device reversely drives the supporting part to rotate to the original position, the driving assembly acts on the supporting assembly 84 to increase the included angle between the first supporting rod 841 and the second supporting rod 842, so as to reduce the height of the supporting assembly 84, so as to drive the supporting seat 82 to descend relative to the base 81 to the supporting part to be matched with the end underframe, and then the end underframe and the supporting part are driven to descend together and be matched with the. Alternatively, in this embodiment, the support member 84 may be configured as a scissor fork or retractable sleeve, and the support member 84 may be configured as two intersecting and relatively rotatable support rods to simplify the overall structure.
In the above embodiment, the driving mechanism includes the driving element and the locking assembly 832, the driving element is disposed on the base 81 and provides a force source for lifting, specifically, the driving element can act on the supporting assembly 84 to change an included angle between the two supporting rods, when the included angle between the two supporting rods reaches a minimum value, that is, the supporting seat 82 rises to a highest position, the locking assembly 832 can lock the relative positions of the two supporting rods, that is, the state of the supporting assembly 84 is kept unchanged, so that the height position of the supporting seat 82 is stable, the supporting seat 82 is prevented from falling due to sudden failure of the driving element, and thus, the lifting device can be ensured to provide stable support for the end chassis in a use state.
Further, the locking assembly 832 comprises a push rod 833 and a rocker 834, and the base 81 is further provided with a pin seat 812, specifically, as shown in fig. 7, the push rod 833 comprises a first section 8331, a bend 8333 and a second section 8332 which are sequentially arranged, wherein the bend 8333 is hinged to the driving member, an end of the first section 8331 is hinged to a bottom end of the first supporting rod 841 and can slide along the first slideway 811, one end of the rocker 834 is hinged to an end of the second section 8332, and the other end of the rocker 834 is hinged to the pin seat 812; the driving member can act on the bending part 8333 and drive the rocker 834 to rotate around the pin seat 812, so as to drive the bottom end of the first supporting rod 841 to slide along the first sliding way 811, and when the included angle between the two reaches the minimum, the bending part 8333 is located above the pin seat 812.
In detail, the opening of the bend 8333 is downward, the rocker 834 is hinged between the second section 8332 and the pin seat 812, the driving member can act on the bend 8333, and the rocker 834 is driven to rotate around a hinge point between the rocker and the pin seat 812, and then the push rod 833 is driven to rotate around the hinge point between the bend 8333 and the driving member, and the first section 8331 can drive the second support rod 842 to move around the hinge point when rotating, because of the limitation of the first slideway 811, the bottom end of the first support rod 841 only can slide along the first slideway 811, so as to realize the change of the included angle between the two support rods.
When the first supporting rod 741 slides along the first sliding channel 711 to the minimum included angle between the two supporting rods, so that the supporting seat 82 rises to the highest position, the bend 8333 is just above the pin seat 812, and the driving member is no longer in action, at this time, if the driving member fails to cause insufficient thrust, the driving action of the driving member on the supporting component 84 is removed, and the support portion continues to press down the supporting seat 82, so that the angle between the two supporting rods tends to increase, because the opening of the bend 8333 faces downward and is located right above the pin seat 812, at this time, the vertical downward pressure cannot move the push rod 833 transversely, so that the rotation of the rocker 834 and the sliding of the first supporting rod 841 along the first sliding channel 811 are limited, and thus the states of the supporting components 84 can be kept unchanged, that is, the included angle between the two supporting rods is unchanged, the height of the supporting seat 72 is unchanged, and the stability is better.
Through the arrangement of the locking device, when the driving member causes the supporting seat 82 to rise to the highest position through the supporting components 84, automatic locking between the supporting components 84 can be achieved, in such a state, the state of each supporting component 84 cannot be changed by vertical force, and only when the supporting seat 82 needs to be lowered, when the pushing rod 833 transversely moves to the bending part 8333 and is separated from the pin seat 812 by the reverse acting force provided by the driving member, unlocking can be achieved, and the bottom end of the first supporting rod 841 is driven to reversely move along the first sliding channel 811 until the supporting seat 82 descends to the lowest state (as shown in fig. 3). The locking assembly 832 can realize locking and unlocking while realizing lifting of the supporting seat 82, does not need to additionally provide a locking part, can simplify the whole structure and simplify operation, and ensures the stability and the convenience of operation of the whole structure.
