Preferably, the steel column comprises a bottom column and a top column; the bottom end of the bottom column is welded with a chassis arranged on the ground, and the top end of the bottom column is welded with a connecting disc; connecting discs are welded at the upper end and the lower end of the top column; the connecting disc of the bottom column is detachably connected with the connecting disc at the lower end of the top column through a bolt; and the connecting disc at the upper end of the top column is detachably connected with the outer side wall of the steel beam through a bolt.
Preferably, the steel beam comprises a connecting beam and a hook beam; the lifting hook is prefabricated on the lifting hook beam; the hook beam is positioned between the two connecting beams, and two ends of the hook beam are detachably connected with the connecting beams through bolts and nuts after being sleeved with the connecting beams; the outer side wall of the connecting beam is detachably connected with the connecting disc at the upper end of the top column through a bolt.
Preferably, the steel column and the steel beam are both made of square steel with the wall thickness of 10 mm.
Preferably, the steel columns are 200mm by 200mm square steels, and the steel beams are 200mm by 300mm square steels.
Preferably, the base plate is a rectangular steel plate with the thickness of 1000mm by 1000mm, and the connecting disc is a rectangular steel plate with the thickness of 500mm by 500 mm.
By last, use the utility model provides a portable lifting hook can obtain following beneficial effect: through the lifting hook that detachable construction constitutes, neglected loading or unable pre-buried installation lifting hook before having solved the people's air defense door leads to the hoist and mount of on-the-spot people's air defense door to have the technical problem of great difficulty, can reuse, conveniently carries.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments of the present invention or the prior art will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive faculty.
Fig. 1 is a schematic view of a portable hook according to an embodiment of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
At present, the traditional civil air defense door lifting hook is embedded in a front top plate of a civil air defense door, the traditional lifting hook is limited by the situation of the front top plate of the door and the situation of error and leakage caused by cooperative communication of field progress, and once the civil air defense door is installed in an neglected mode or cannot be embedded, the civil air defense door is lifted in a field mode, so that great problems and inconvenience exist.
Therefore, it is required to provide a reusable and portable hook, and referring to fig. 1, the present embodiment provides a portable hook for installing a civil air defense door, which includes a portal-shaped bracket formed by detachably connecting two steel columns 10 and a steel beam 20, and a hook 30 prefabricated on the steel beam 20.
Specifically, the steel column 10 includes a bottom column 11 and a top column 12. A chassis 13 arranged on the ground is welded at the bottom end of the bottom column 11, and a connecting disc 14 is welded at the top end; connecting discs 14 are welded to the upper and lower ends of the top pillar 12. Wherein the connecting disc 14 of the bottom column 11 is detachably connected with the connecting disc 14 at the lower end of the top column 12 through a bolt, and the connecting disc 14 at the upper end of the top column 12 is detachably connected with the outer side wall of the steel beam 20 through a bolt.
The steel beam 20 comprises a connecting beam 21 and a hook beam 22, and the hook 30 is prefabricated on the hook beam 22. The hook beam 22 is located between the two connecting beams 21, and both ends of the hook beam are detachably connected with the connecting beams 21 through bolts and nuts after being sleeved. The outer side wall of the connecting beam 21 is detachably connected with the connecting disc 14 at the upper end of the top column 12 through a bolt.
Through above-mentioned structure, can dismantle into a plurality of component with portable lifting hook, also can make up into a complete lifting hook 30 with a plurality of component parts when people's air defense door installation, lifting hook 30 through detachable construction constitution has solved neglected loading or unable pre-buried installation lifting hook 30 before people's air defense door, leads to the hoist and mount of on-the-spot people's air defense door to have the technical problem of great difficulty.
