The invention discloses an automatic jacking in-place device and method for tower crane standard section. An upper frame and a lower frame of the device are fastened and fixed to an upper tower cranestandard section a lower tower crane standard section respectively, four jacking hydraulic cylinders are uniformly distributed and vertically arranged between the upper frame and the lower frame, piston rods of the jacking hydraulic cylinders are fixedly connected to the upper frame, and cylinder barrels of the jacking hydraulic cylinders are fixedly connected to the lower frame; and a turnover platform is hinged to the upper frame and is used for containing a to-be-installed standard section, and the turnover platform is driven by a motor. The method comprises the following steps that the upper tower crane standard section and the lower tower crane standard section are disconnected, and the upper frame and the upper tower crane standard section are synchronously jacked to a specified distance which is met by the requirement; the turnover platform is adjusted to a horizontal state; the to-be-installed standard section is hoisted to the turnover platform in an inverted state; the turnover platform and the to-be-installed standard section are synchronously adjusted to an upright state, the to-be-installed standard section is enabled to fall onto the lower tower crane standard sectionis fixedly connected to the lower tower crane standard section, and the upper tower crane standard section is enabled to fall onto the to-be-installed standard section and is fixedly connected to theto-be-installed standard section; and tightening between the lower frame and the lower tower crane standard section are relieved, and the cylinder barrels of the jacking hydraulic cylinders are lifted back to the initial position.
Description
technical field [0001] The invention belongs to the technical field of tower cranes, and in particular relates to a device and method for automatically jacking and positioning a standard section of a tower crane. Background technique [0002] In the construction process of prefabricated buildings, the hoisting work of prefabricated components is basically completed by tower cranes. As the height of the building continues to increase, the tower crane also needs to cooperate with the building to climb the height, and the climbing of the tower crane The process is the installation process of the standard section. [0003] At present, the automation degree of the installation process of the standard section of the tower crane is relatively low, and a large amount of manpower is required for assistance, resulting in low installation efficiency. It also increases the danger of working at heights. Contents of the invention [0004] Aiming at the problems existing in the prior a...
