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.

Referring to fig. 1, an embodiment of the present application discloses a hydraulic lifting machine, including: the vertical column 1 comprises a longitudinal beam and a top plate 14 arranged at the upper end of the longitudinal beam; the sliding table 2 is arranged on the longitudinal beam in a manner of moving along the vertical direction; wherein, a through hole 15 for the sliding table 2 to penetrate out is arranged on the top plate 14.

By the above mechanism, the slide table 2 can be passed out of the through hole 15 of the top plate 14 in the process of moving upward. The highest extreme position of the ramp 2 is thus no longer limited by the top plate 14 of the upright 1. Meanwhile, the height of the upright post 1 is not increased, so that the overall strength of the upright post 1 is not affected.

In particular, the hydraulic lift in the present application, like other hydraulic lifts, also comprises bases 5 arranged below the uprights 1 and a connecting plate 6 arranged between the bases 5.

Referring to fig. 2, in the present embodiment, the side member includes a first side wall 11, and a second side wall 12 and a third side wall 13 respectively disposed at front and rear sides of the side wall, a groove is formed between the first side wall 11, the second side wall 12, and the third side wall 13, and the top plate 14 closes the groove at a top of the side member.

In particular, the recess is open on its side facing away from the first side wall 11, so that the width of the ramp 2 can be unrestricted in the transverse direction, in order to further improve the support of the ramp 2 for the vehicle.

Specifically, a rack 4 is arranged on the upright post 1, and a safety bar 3 corresponding to the rack 4 is arranged on the sliding table 2. The quantity of stand 1 is two, is provided with two racks 4 along longitudinal separation range on every stand 1, the quantity of slip table 2 is two, every slip table 2 set up with the bumper strip 3 that rack 4 corresponds, hydraulic pressure machine of lifting is still including and only one rope, the rope can be simultaneously to the height of slip table 2 control. When the rope is unlocked, the two slipways 2 can be lifted and lowered in synchronization to provide stable control of the vehicle disposed on the slipways 2.

The length between the racks 4 can be increased, so that a plurality of racks 4 (for example, two racks) arranged at intervals in the longitudinal direction can be arranged on the upright post 1, and the safety bars 3 corresponding to the plurality of racks 4 are arranged on the sliding table 2. The safety bar 3 of the slide table 2 is in contact with at least one of the plurality of racks 4 when the slide table 2 is in any one position. For example, for strength, the safety bar 3 of the slide table 2 may be simultaneously in contact with one or more racks 4 of the column 1 when it is in any position.
