detailed description

The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings, so as to make the technical solutions of the present invention easier to understand and grasp.

As shown in Figures 1, 2, 3, and 4, a hydraulic lifting and transporting device includes two outer feet 1 arranged symmetrically from left to right, and an inner foot 2 between the two outer feet 1, The tops of the two outer feet 1 are provided with a top beam 3, the bottom of the top beam 3 can slide along the length direction of the inner feet 2 and a crossbeam 4 is provided, and the bottom of the crossbeam 4 is provided with four jacks 5, and the bottom of the jacks 5 is connected to Inner foot 2 contacts.

Wherein the four corners of the beam 4 are respectively fixed with a first connecting seat 41, and each first connecting seat 41 is connected with a shrinking hydraulic cylinder 42 through a pin; correspondingly, the inner foot seat 2 is provided with four Two connecting seats 21, the second connecting seat 21 is connected with the piston rod of the retracting hydraulic cylinder 42 through a pin.

The top of the inner foot seat 2 is provided with two third connecting seats 22, the third connecting seats 22 are connected with the first joint 23 through the pin shaft, and the first joint 23 is connected with the horizontal hydraulic cylinder 24 through the pin shaft; correspondingly, one of them Two fourth connecting seats 11 are arranged on the outer base 1, and the fourth connecting seats 11 are connected with the second joint 12 through the pin shaft, and the second joint 12 is connected with the piston rod of the transverse hydraulic cylinder 24 through the pin shaft.

As shown in Figure 3, the left outer wall of the top beam 3 is fixed with a fifth connecting seat 31, and the fifth connecting seat 31 is connected with a longitudinal hydraulic cylinder 32 through a pin shaft, and the longitudinal hydraulic cylinder 3 is arranged along the length direction of the outer foot seat 1; As shown in FIG. 4 , correspondingly, the top of the beam 4 is provided with a sixth connection seat 33 , and the sixth connection seat 33 is connected to the piston rod of the longitudinal hydraulic cylinder 32 through a pin.

The working principle of the present invention is as follows:

(1) Horizontal working principle: in the initial state, loads are placed on the top beam 3, and the inner foot 2 is raised by shrinking the hydraulic cylinder 42. At this time, the outer foot 1 bears the load; the jack 5 raises the outer foot 1 and Loading, at this time, the load is borne by the inner foot seat 2; the lateral hydraulic cylinder 24 works to move the outer foot seat 1 together with the load forward, and the inner foot seat 2 is still bearing the load at this time, and the load has moved forward for a certain distance; the jack 5 Contraction, shrinking hydraulic cylinder 42 raises the inner foot 2, at this time, the outer foot 1 bears the load, and the inner foot 2 is suspended; the horizontal hydraulic cylinder 24 moves the inner foot 2 forward, and the device state returns to the beginning at this time state, and prepare for the next cycle sequence.
