Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

FIG. 1 is a perspective view of the overall structure of the double-deck platform leveling device of the present invention; fig. 2 is a structural sectional view of the double-deck platform leveling device in an initial state; fig. 3 is the structural section view of the jacking state of the double-deck platform leveling device of the present invention.

Referring to fig. 1 to 3, a leveling device for a double-deck platform includes an upper platform 1, a lower platform 2, a jacking mechanism disposed on the lower platform 2 for lifting the upper platform 1, and a plurality of leveling legs 3 for supporting the lower platform 2, wherein the lower platform 2 is mounted at the bottom of a special vehicle or a workbench, and the upper platform 1 is used for jacking vehicle-mounted equipment to be leveled so as to meet leveling requirements.

Specifically, the jacking mechanism comprises a driving source, a transmission mechanism connected with the driving source and a jacking assembly used for lifting the upper platform 1. The jacking assembly comprises a box body 6 fixedly mounted on the lower platform 2, an outer pipe 7 fixedly connected to the box body 6, and a screw rod 8 sleeved in the outer pipe 7, wherein the screw rod 8 is connected with a transmission mechanism and moves in an extending manner along the length direction of the outer pipe 7, and the top end of the screw rod 8 supports the upper platform 1. More specifically, this driving source is motor 4, and the output shaft of motor 4 links to each other with drive mechanism, and drive mechanism here is gear train 5, and gear train 5 links to each other with lead screw 8 and drives lead screw 8 and rotate, and lead screw 8 supports upper mounting plate 1 to realize climbing mechanism to the jacking operation of upper mounting plate 1. The driving source can also be driven by an oil cylinder, and the upper platform 1 is jacked by an oil cylinder rod, so that jacking operation of the upper platform 1 is realized. But in this embodiment we are implemented using a motor 4 drive.

Furthermore, a leveling component is arranged at the supporting position of the top end of the screw rod 8 and the upper platform 1 and used for leveling vehicle-mounted equipment loaded on the upper platform 1, and the leveling requirement is met. The leveling component comprises an upper mounting cover 9 sleeved at the top end of the screw rod 8, a thrust bearing 10 embedded in the upper mounting cover 9 and a locking nut 11 mounted on the upper mounting cover 9. When the upper platform is adjusted to be flat, the locking nut 11 is unscrewed, so that the upper platform 1 is slightly adjusted by the thrust bearing 10 in the jacking process, and the upper platform 1 is prevented from being clamped in the jacking process.

In this embodiment, upper mounting plate 1 and lower platform 2 are square structure, and the quantity of adjusting the landing leg is 4, sets up on platform 2's four corners down for the climbing mechanism that goes up and down upper mounting plate 1 also is 4, has 4 motors 4, 4 lead screws 8 promptly, sets up on platform 2's four corners down, supports upper mounting plate 1's four corners, and during the jack-up, four motors 4 are simultaneous working, make the jack-up stable.

The working process is as follows: during the initial state, upper mounting plate 1 hugs closely on lower mounting plate 2, and during lead screw 8 shrink went into outer tube 7, lock nut 11 at lead screw 8 top was in the lock state of dying, and upper mounting plate 1 can not the lifting. When the lifting mechanism is lifted, the locking nut 11 is loosened, the upper platform 1 is in a free state, the four screw rods 8 are prevented from being clamped mutually when being lifted synchronously, the power of the driving source motor 4 is transmitted through the transmission mechanism gear set 5 to drive the screw rods 8 to rotate, so that the lifting operation of the upper platform 1 is realized, the upper platform 1 can be finely adjusted front and back, left and right under the action of the thrust bearing 10, the upper platform ascends at the same speed as the four screw rods 8, and the screw rods 8 are driven by the nuts to move spirally. When the upper platform 1 rises, the lower platform 2 can be synchronously lifted under the action of the leveling supporting legs 3, when the leveling stroke of the lower layer foundation, namely the lower platform 2, is finished, the synchronous lifting stroke of the upper platform 1 is also finished, then the locking nut 11 at the top of the synchronous lifting is locked manually, and the lower platform 2 can continue to level until the leveling is finished.

The utility model discloses a leveling operation is realized to double-deck platform, has increased the effective stroke in the unit height, has solved the limited problem of installation space of special type vehicle or workstation bottom, and occupation space is little, and in addition, this double-deck platform's support stability is good, and the jacking is fast, and the concentricity can be guaranteed with the 2 synchronous jacking of lower platform to upper mounting plate 1.
