Problems solved by technology

[0003] In order to solve the above technical problems, the present invention provides a self-climbing steel beam crane capable of variable amplitude. By adopting the crane of the present invention, when the steel beam is hoisted, the height and position of the steel beam can be adjusted. Beam alignment, the sliding mechanism of the device is set on the top of the lifting truss, so that the steel girder can be adjusted by sliding longitudinally, and then the elevation of the steel girder is adjusted through the hoist. It is very convenient to install the steel girder, which solves the traditional complex The cost of the luffing mechanism tower crane with rotating boom is too high, and it is easy to collide with the tower column

Embodiment 1

[0031] see Figure 1-7 , a self-climbing steel beam crane capable of variable amplitude, which includes a concrete beam, an embedded part 17 is fixed on the concrete beam, a column 8 is fixedly installed on the embedded part 17, and the top of the column 8 A lifting truss 6 is fixedly installed, and the top of the lifting truss 6 is fitted with a longitudinal sliding seat 1 through sliding fit, and a hoisting and lifting device for lifting heavy objects is installed in cooperation between the longitudinal moving sliding seat 1 and the lifting truss 6 ; The side of the column 8 is equipped with a climbing mechanism for driving its alternate lifting. By adopting the self-climbing steel beam crane with the above structure, it replaces the traditional luffing mechanism tower crane with rotating boom, and is used for the installation of steel beam 16. During the installation process, it is convenient to move the sliding seat 1 vertically The longitudinal installation position of t...

Embodiment 2

[0038] The use method of any one of the variable-amplitude self-climbing steel-tied beam cranes includes the following steps:

[0039] Step 1: Form the space structure of the hoisting truss 6 through parallel connecting rods, and fix it on the steel tie beam 16;

[0040] Step 2: Drive the longitudinal sliding seat 1 to move at the bottom of the lifting truss 6 through the guide chain, and adjust the longitudinal position of the steel tie beam 16 to be installed;

[0041] Step 3: After the longitudinal position adjustment is completed, lock it on the lifting truss 6 through the locking device 4, then start the winch 5, and drive the moving pulley mechanism 2 and the spreader 3 through the winch 5 to adjust the height position of the steel beam 16. adjustment, and then realize the butt joint of the steel tie beam 16;

[0042] Step 4: After the steel tie beam 16 of the bottom section is installed, start the climbing mechanism again, push the upward adjustment shoe 10 through the...

Abstract

The invention provides a self-climbing steel beam crane with the amplitude capable of being varied and a use method of the self-climbing steel beam crane. The self-climbing steel beam crane includes aconcrete cross beam, an embedded part is fixed on the concrete cross beam, vertical columns are fixedly installed on the embedded part, lifting trusses are fixedly installed at the tops of the vertical columns, longitudinal moving sliding seats are installed at the tops of the lifting trusses in a sliding fit mode, a winding lifting device for lifting heavy objects is installed between the longitudinal moving sliding seats and the lifting trusses in a fit mode, and a climbing mechanism for driving the vertical columns to alternatively lift is installed on the side faces of the vertical columns. According to the crane, when hoisting steel beams, steel beam alignment can be adjusted when the height and position remain unchanged, a sliding mechanism of the crane is arranged at the top ends of the lifting trusses to make the steel beams longitudinally and slidably adjust, then the elevation of the steel beams is adjusted through a winch, the steel beams are extremely conveniently installed, and the problems that the cost is too high and tower columns are prone to colliding with traditional complicated variable amplitude mechanism tower cranes according to the traditional complicated variable amplitude mechanism tower cranes with rotating big arms are well solved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a self-climbing steel beam crane capable of variable amplitude. Background technique [0002] The installation of steel girders is a very important link in bridge construction. When the steel girders need to move longitudinally, the traditional construction method is to install large-tonnage tower cranes. The disadvantages of this process are: the requirements for the foundation of the tower crane are high, and the tower crane is attached to work and the weight of a single piece Large, troublesome to install, and extremely expensive. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a self-climbing steel beam crane capable of variable amplitude. By adopting the crane of the present invention, when the steel beam is hoisted, the height and position of the steel beam can be adjusted. Beam alignment, the ...
