Abstract
The utility model discloses a detachable limiting device which comprises a flitch and a limiter, wherein the flitch is fixed on one side surface of a lower chord, four threaded holes I are formed in the flitch, and the limiter is in threaded connection with the flitch through bolts. The limiter is an angle steel. Four threaded holes II are formed in the upper surface of the lower chord and are the same as the diameter of the threaded hole I in the flitch. The structure can ensure that the limiter is convenient to disassemble and assemble and is not easy to lose.
Description
Technical Field
The utility model relates to the technical field of tower cranes, in particular to a detachable limiting device.
Background
The tower crane is usually loaded into a container when being exported, for medium and large tower crane export models, a traditional welding mode is always adopted for a boom limiting device at home and abroad, the boom is difficult to be loaded into the container in the mode, the boom limiting device is usually subjected to gas cutting before the tower crane is loaded into the container, and the boom limiting device is welded again when the tower crane is loaded into the container.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a detachable limiting device to solve the problem that a cargo boom of a tower crane is not easy to be loaded into a container.
In order to achieve the purpose, the detachable limiting device comprises a flitch and a limiter, wherein the flitch is fixed on one side surface of a lower chord, four threaded holes I are formed in the flitch, and the limiter is in threaded connection with the flitch through bolts.
Further, the limiter is an angle steel.
Furthermore, four threaded holes II are formed in the upper surface of the lower chord and have the same diameter as the threaded holes I in the flitch.
The utility model has the beneficial effects that: the limiting device is detachably arranged, so that the crane boom can be arranged in the container, and the complicated operations of gas cutting before boxing and welding after field installation are avoided; the lower chord of the cargo boom is provided with a threaded hole, and when the cargo boom is loaded into a container, the angle steel is temporarily fixed near the flitch for subsequent installation.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the construction of the flitch plate;
in the figure, 1-flitch, 11-threaded hole I, 2-angle steel, 3-bolt, 4-lower chord and 41-threaded hole II.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in figures 1-2, the detachable limiting device comprises a flitch 1 and a limiter, wherein the flitch 1 is fixed on one side surface of a lower chord 4, four threaded holes I11 are formed in the flitch 1, and the limiter is in threaded connection with the flitch 1 through bolts 3. The limiter is an angle iron 2. Four threaded holes II41 are formed in the upper surface of the lower chord 4, and the diameter of each threaded hole II41 is the same as that of the threaded hole I11 in the flitch 1. Compared with the prior art, set the stopper to detachable mode, can be when the jib loading boom needs vanning, dismantle very conveniently, the loaded down with trivial details operation of rewelding when having avoided on-the-spot cutting and installation with the stopper, when the jib loading boom vanning, in order to prevent that the stopper from losing or placing at will, set up four screw holes on the lower chord 4 of jib loading boom, can fix the stopper on the lower chord temporarily, can directly take off when reinstalling to connect can.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes which can be made within the knowledge of those skilled in the art without departing from the gist of the present invention are within the scope of the claims of the present invention.
