Abstract
The utility model relates to a detachable long-standard section inclined ladder for a tower crane; each standard section of the inclined ladder is divided into two sections, and comprises a long ladder (1), a short ladder (2), a U-shaped support rod (3), a clamp plate (4), two support rods (5) and a protecting ring (6), wherein the lower end of the long ladder is fastened on the standards section by a U-shaped bracket through the clamp plate by a bolt; the upper end of the long ladder and the lower end of the short ladder are fixed on a platform of the standards section by bolts; and the short ladder is connected with the long adder by the two support rods. The whole set of ladder device is simple in manufacture, low in cost and easy to install. When the ladder is in use, the climbing is labor-saving, and the ladder is safe and reliable.
Description
Technical field
The utility model relates to and is applicable to removable tower crane undersetting constructional device and the installation method thereof of a kind of supporting leg large-scale and ultra-large type tower machine.
Background technology
Along with the continuous increase of tower machine series exploitation tonnage, the oad of tower machine also continues to increase; And be control traffic cost and the restriction that receives the shipping container size; The assembly type development and Design of tower machine is imperative; Because undersetting in the past adopts the box type construction unit design; Bulky, for reducing the volume of undersetting as far as possible, the removable undersetting of a kind of supporting leg can overcome the above problems well.
Summary of the invention
The purpose of the utility model is for large-scale and ultra-large type tower machine provide a kind of supporting leg removable undersetting, reduces the volume of undersetting as far as possible, with transportation and the control traffic cost that is suitable for shipping container.
For realizing above-mentioned purpose; The utility model is taked following technical scheme: this removable undersetting comprises: undersetting casing 1, supporting leg 2, bearing pin 3; Wherein the plane links to each other with high strength bolt with pivoting support on the undersetting casing, and the bottom main chord links to each other with bearing pin with body of the tower; Supporting leg is connected with undersetting casing and climbing frame respectively through bearing pin.
Compare former integral type undersetting, both realized its functional requirement, reduced it again effectively and split volume.
The utility model has the advantages that:
1, the undersetting casing adopts bearing pin to be connected with supporting leg, and is simple and compact for structure, easy for installation;
2, reduced the fractionation volume of undersetting effectively, reduced traffic cost greatly and help exporting the needs of sea-freight.
Description of drawings
Fig. 1 is the undersetting structural representation.
The specific embodiment
Undersetting casing 1, supporting leg 2, bearing pin 3, wherein the undersetting casing adopts independent design, and last plane links to each other with high strength bolt with pivoting support, and the bottom main chord links to each other with bearing pin with body of the tower; Supporting leg is connected with undersetting casing and climbing frame respectively through bearing pin.
Simple and compact for structure, easy for installation; This scheme is applicable to each large-scale and ultra-large type tower machine, and is practical and convenient, is convenient to promote.
