Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0040] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0041] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses a hydraulic lifting device and a lifting operation platform. The hydraulic lifting device is installed on the platform and used for driving pile legs to move up and down in thevertical direction relative to the platform. The hydraulic lifting device comprises an upper ring beam, a lower ring beam, first lifting oil cylinders and second lifting oil cylinders, wherein the upper ring beam is used for being detachably connected with the pile legs, the lower ring beam is coaxially arranged with the upper ring beam in a spaced mode and is used for being detachably connectedwith the pile legs, the first lifting oil cylinders are mounted on the platform, the first lifting oil cylinders are connected with the upper ring beam, and are used for driving the pile legs to movefor N pitches in the specified direction, N is a positive number from 0 to 1, the second lifting oil cylinders are mounted on the platform, and the second lifting oil cylinders are connected with thelower ring beam and are used for driving the pile legs to move for (1-N) pitches in the specified direction. According to the technical scheme, the two first lifting oil cylinders and the two second lifting oil cylinders are arranged to disperse the force supplied to the pile legs, so that the operation of the lifting device is stabler.
Description
technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a hydraulic lifting device and a lifting operation platform. Background technique [0002] The hydraulic lifting device is widely used in the water work platform, and it can cooperate with the pile legs to drive the water work platform to perform lifting movement in the vertical direction. [0003] In the prior art, the hydraulic lifting device mainly includes: a moving ring beam, a fixed ring beam, a lifting cylinder and a bolt assembly. The lifting cylinder drives the moving ring beam to achieve extension and contraction, and then realizes the relative displacement between the moving ring beam, fixed ring beam and pile legs, making the rise and fall of the water work platform a reality. [0004] In the process of realizing the above-mentioned technical effects, there are at least the following problems: [0005] The lifting cylinder provides a pitch displ...
