Embodiment approach

[0028] The 1,000-ton lifting frame equipment is a large-scale special equipment that is transported to the construction site for assembly, inspection and acceptance after each component is produced by the manufacturer, and then put into use. Lifting frame equipment is composed of support system, walking system, power system, hydraulic system, electrical system and safety monitoring system. During the construction process, the 1,000-ton lifting frame equipment has high lifting height, heavy lifting weight, segmented installation and overall hoisting, and fast construction progress. It can be applied to special construction conditions in the beam lifting area with limited space and pier heights exceeding 30 meters.

[0029] The following is an example of a 1000-ton separate lifting frame composed of TLJ500-36 beam lifting machine, YLS1000 beam transporting vehicle and JQS1000 bridge erecting machine.

[0030] There are two TLJ500-36 beam lifting machines in the whole set of equi...

Abstract

The invention relates to the technical field of installation of large special hoisting equipment, and provides an installation construction process for 1000-ton hoisting and transporting frame equipment. The installation construction process comprises the following steps of step 1, installation preparation, step 2, girder crane assembling, step 3, girder transporting vehicle assembling, step 4, bridge girder erection machine assembling and step 5, whole hoisting and transporting frame equipment debugging. The installation construction process has the beneficial effects that accumulation of steel structure mounting errors is avoided by adopting a diagonal method and a suspension rope method, and safety and reliability of equipment are ensured; an installation site is planned in advance, secondary transfer of the equipment is avoided, and the installation efficiency is greatly improved; and a bridge girder erection machine is hoisted and installed by a girder crane, so that the use of atruck crane is reduced, and the installation cost is saved.

Description

technical field [0001] The invention relates to the technical field of installation of large-scale special lifting equipment, and more specifically relates to an installation and construction process for 1000-ton lifting frame equipment. Background technique [0002] At present, the domestic high-speed railway infrastructure construction is developing rapidly. With the diversified development of special equipment for railway bridge lifting frames, major construction companies continue to research, innovate and improve the installation and construction technology of lifting frame special equipment according to the actual situation on site, making it possible to improve The installation process and method of special equipment for transport racks tend to be standardized and rationalized. The traditional installation method is mainly for the installation of lifting rack equipment with a lifting height of 30 meters or less and a rated lifting capacity of 900 tons or less. Compute...
