Problems solved by technology
[0002] With the rapid development of domestic petrochemical and coal chemical industries, the weight and size of large-scale equipment in the chemical plant area continue to increase, and the method of hoisting with conventional cranes has been unable to meet the hoisting requirements of large-scale equipment
The gantry hydraulic lifting system used in the lifting of chemical equipment has been put into use. The hydraulic lifting device is a new type of lifting equipment integrating hydraulic, electrical and control technologies. It can vertically lift extra-large and heavy parts under difficult operating conditions Horizontal translation and safety in place, with the use of large hydraulic lifting and hoisting systems, new requirements have been put forward for the installation and removal methods of large hydraulic lifting devices. However, the existing hydraulic lifting devices have various installation and removal methods, but there are parts Large volume, heavy weight, inconvenient long-distance transportation, or cumbersome installation and dismantling, complicated operation, unsafe and other problems, bring a lot of inconvenience to the use and operation on site

Embodiment Construction
[0026] The installation method of the portal type hydraulic lifting device of the present invention comprises the following steps, (1) installing the base 11, at first shoveling the pad iron nest on the ground, placing the pad iron in the pad iron nest, adjusting the height and levelness with the pad iron to form Install the foundation, and then use a 50t truck crane to place each component of the base 11 on the pad iron, such as figure 1 As shown, the base includes two first base members 111 with the same structure, two second base members 112 with the same structure and two third base members 113 with the same structure. Two base components form a well-shaped shape, and then the adjacent two base components are connected by bolts, and the above-mentioned base components are welded with fixing parts 114, such as Figure 2a , 2b , 2c, there are pre-embedded bolt holes 115 on the fixing part 114, and M48 pre-embedded bolts are arranged on the installation foundation, and the c...

Abstract
The invention relates to a mounting method for a door type hydraulic pressure lifting device. The mounting method comprises the following steps: a base is mounted, wherein structural members are mutually connected on a mounting foundation, then the structural members are connected with the mounting foundation, a first portal frame and a second portal frame are mounted, after standard nodes and top nodes are respectively assembled, a hoisting manner is used for successively placing the standard nodes from bottom to top, and the top nodes are placed at the top; load-bearing beams are mounted, wherein firstly the load-bearing beams are assembled well on the ground and then hoisted and mounted, and a crane beam is assembled well on the ground and then hoisted and mounted; a hydraulic pressure hoisting system is mounted, finally, a pumping station and a remote control and monitor system are mounted. The mounting method for the door type hydraulic pressure lifting device is convenient for long-distance transport, reduces the amount of high-rise operations, is simple to operate, and is convenient to mount and demount.
