Background
When the super-tonnage tower crane adopts a hydraulic cylinder to jack, the hydraulic cylinder and the cylinder box body beam need to be installed in high altitude, and the size and the weight of the corresponding hydraulic cylinder are increased along with the increase of the size of the cross section of the tower body of the large-tonnage tower crane. The requirements on the installation accuracy and the installation efficiency of the hydraulic oil cylinder are high, if the angle and the position of the hydraulic oil cylinder are deviated, the installation efficiency of the hydraulic oil cylinder is seriously influenced, and meanwhile, the requirement on hoisting equipment is higher and higher due to the increase of the whole weight of the climbing frame.
After the hydraulic oil cylinder and the jacking cross beam are installed, the whole weight is overlarge, the installation space is limited, the installation in high altitude is extremely difficult in the existing mode, and the requirement on hoisting equipment is overhigh. The installation process of the existing tower crane has the following defects: the climbing frame with the hydraulic oil cylinder and the jacking cross beam is installed in integral hoisting, the requirement on hoisting equipment is too high when the weight of the climbing frame of the ultra-large tonnage tower crane is too high, the integral installation of the climbing frame is difficult due to too large weight, the installation efficiency is low, the installation cost is high, the installation position is not accurate, and the installation process is complex and the safety accident is easy to occur.

thirdly, mounting a cushion block on the step I on the upper side of the foundation section to be heightened, and placing a support rod of the climbing frame on an auxiliary cushion block;
the fourth step: and connecting the hydraulic oil cylinder with the climbing frame to complete installation.
The first step is specifically as follows: hanging the jacking cross beam on the step I at the lowest layer on two sides of the foundation section, and penetrating an anti-falling pin shaft;
the second step is specifically as follows: lifting a hydraulic oil cylinder, enabling a push rod to face downwards, installing a push rod head into an ear plate of a jacking cross beam, penetrating a pin shaft, installing a shaft end baffle, enabling the oil cylinder to lean against a cross web member on the uppermost layer of a foundation section under the assistance of a chain block, and temporarily fixing the oil cylinder by using a chain block pocket;
the third step is specifically as follows: firstly, placing auxiliary cushion blocks on 4 steps on the upper layer of the basic section, then hoisting the climbing frame, slowly sleeving the climbing frame from the upper part, supporting four support rods on the auxiliary cushion blocks of the steps on the upper layer of the basic section, and ensuring that the support rods are reliably clamped into the steps.
The fourth step is specifically as follows: after the hydraulic oil cylinder and the headless pin shaft are installed, the hydraulic oil cylinder and the headless pin shaft are connected with the upper lug plate of the climbing frame and fixed through the bolt pin shaft and the like to complete installation.
The invention has the beneficial effects that: the hydraulic oil cylinder and the jacking oil cylinder are arranged on the foundation section in advance in the installation process, so that the influence of the gravity of the hydraulic oil cylinder can be reduced, the safety is high, the requirement on hoisting equipment can be reduced, and the cost is saved. The installation position of the hydraulic oil cylinder is determined after the hydraulic oil cylinder is fixed at the lower end, so that the installation precision can be improved, and the process is stable. The installation sequence is clear and definite and the precision is high, can practice thrift manpower and materials, reduce cost.
