Problems solved by technology

At present, the existing hydraulic lifting or jacking systems all adopt the portal structure with cable wind rope. The defects of this structure are: first, the portal structure has relatively large defects and difficulties in hoisting high foundation or segmented equipment and structures Second, the setting of the cable wind rope has great restrictions on the installation of equipment, process pipelines, steel structures and other construction around the suspended object

Embodiment 1

[0022] The present invention proposes an integrated mobile hydraulic lifting system with a cable-free wind rope, such as figure 1 As shown, the system includes two parallel running rails 5 and four tower columns 1, the two running rails 5 are fixed on the ground, the bottom of the tower column 1 is set in the running rails 5, and the tower The column 1 can slide along the running track 5 . Two of the tower columns 1 are arranged on one running track, and the other two tower columns 1 are correspondingly arranged on the second running track. The tops of the tower columns arranged on the same running track are respectively connected by the first hoisting beam 3 and the second hoisting beam 3'. The tower columns arranged on the two running tracks correspond to each other, and the tops of the tower columns 1 corresponding to each other are respectively connected by tower connecting beams 2 . The tower column 1 and the tower connecting beam 2 form a frame structure tower. The fi...

Embodiment 2

[0032] In this embodiment, the third hoisting beam is fixed on the upper surfaces of the first hoisting beam and the second hoisting beam, and there is no need to arrange rails on the upper surfaces of the first hoisting beam and the second hoisting beam.

[0033] Others are the same as embodiment 1.

Abstract

The invention relates to the field of lifting and hoisting, in particular to an integrally moving on-load hydraulic lifting system without a mooring rope and a lifting method. The integrally moving on-load hydraulic lifting system without the mooring rope comprises a tower and two parallel running rails, the tower comprises four vertical posts and connection crossbeams, and the two running rails are fixed on the ground. The bottom ends of the four vertical posts are arranged in the running rails so that the vertical posts can slide in the running rails. Two of the vertical posts are arranged on one of the running rails, and the other two vertical posts are arranged on the other running rail, the vertical posts on the two running rails correspond to each other, and the top ends of the corresponding vertical posts are connected through the connection crossbeams. The vertical posts and the connection crossbeams form the tower in the frame type structure. Without the mooring rope, the hydraulic lifting system can integrally move in long distance in an on-load manner, and lifting is safe and stable and economical.

Description

technical field [0001] The invention relates to the field of hoisting and hoisting, in particular to an integrated mobile hydraulic lifting system and a hydraulic lifting method with a cable-free wind rope. Background technique [0002] With the increase in the scale of petroleum refining and chemical plants, there are more and more heavy equipment in the plant, and with the improvement of transportation capacity and manufacturing level, it has become inevitable for super long and heavy equipment to enter the installation site as a whole. Compared with hoisting by crane, using hydraulic lifting or jacking system for hoisting extra-large equipment has great advantages in terms of safety and reliability, hoisting capacity, entry and exit costs, floor space and idle costs, etc., and has been widely accepted. Applications. At present, the existing hydraulic lifting or jacking systems all adopt the portal structure with cable wind rope. The defects of this structure are: first, ...
