Description
Technical field
The utility model relates to a kind of instrument, especially relates to a kind of lifting device that is exclusively used in I-beam section, belongs to mechanical field.
Background technology
I-beam section, also referred to as girder steel, is that cross section is the rectangular steel of I-shaped shape.I-beam section divides common I-beam section and lightweight I-beam, three kinds of H shaped steel.That cross sectional shape is the shaped steel of flute profile.I-beam section is widely used in various building structure, bridge, vehicle, support, machinery etc.The edge of a wing of common I-beam section and lightweight I-beam by root to attenuation gradually on limit, there is certain angle, the model of common I-beam section and lightweight I-beam is to represent with the Arabic number of the high cms of its waist, web, edge of a wing thickness its specifications different from flange width represent with the milli number of waist wide (the b) * waist of high (h) * leg thick (d), as " general work 160 * 88 * 6 ", represent that waist high is 160 millimeters, leg is wide is 88 millimeters, and waist is thick is the common I-beam section of 6 millimeters." light industry 160 * 81 * 5 ", represents that waist high is 160 millimeters, and leg is wide is 81 millimeters, and waist is thick is the lightweight I-beam of 5 millimeters.
No matter i shaped steel is coventional type or light-duty, because sectional dimension is all relatively high, narrower, therefore the moment of inertia of two main sleeves of pair cross-section differs larger, therefore, generally only can be used directly in and in its web plane, be subject to curved member or formed lattice primary structure member.To axis compression member or also having crooked member all should not adopt perpendicular to web plane, this just makes it on field of application, have great limitation; H shaped steel belongs to high-efficiency and economic and cuts out face section bar (other also has light gauge cold-formed steel shape, profiled sheet etc.), and because cross sectional shape is reasonable, they can make steel bring into play higher usefulness, improves load-carrying capacity.What be different from unskilled labor font is that the edge of a wing of H type steel is widened, and inside and outside surface is normally parallel, can be convenient to like this be connected with other members with high strength bolt.Its size forms series rationally, and model is complete, is convenient to design and selects.I-beam section is due to the abnormity of its structure, and the sharp edge edge of containing causes easily equipment or operating personal being damaged when carrying, adopts bundling type transportation easily to come off in vibrations process.
Utility model content
The purpose of this utility model is to overcome the problems that existing I-beam section exists when carrying, designed a kind of lifting device that is exclusively used in I-beam section, this lifting device simple in structure, principle is easy, can carry out repeated usage, manufacture, use cost is low, utilize the structure arranging, I-beam section is clamped, make I-beam section stablize and can not come off in hoisting process, efficiency is high, prevents safety misadventure.
The purpose of this utility model is achieved through the following technical solutions: a kind of lifting device that is exclusively used in I-beam section, comprise the fixed way that is regular tetragonal body structure, on a wall of described fixed way, be provided with projection, projection and fixed way are welded as integral structure, and the line between the center of projection and the center of fixed way is parallel with plumb bob vertical, on projection, be provided with through hole, the center of through hole and the center superposition of projection, and the line of centers of through hole, perpendicular to the line between the center of projection and the center of fixed way, is provided with anchor fitting on fixed way.
Described anchor fitting comprises and is arranged on the groove that is rectangular structure on fixed way, the center of groove and the center superposition of fixed way, and the line of centers of groove and the line of centers of through hole parallel.
Described fixed way forms groove away from one end indent of projection, and groove is communicated with the both sides of fixed way, and the center of groove is arranged on the line between the center of projection and the center of fixed way.
Described groove is communicated with groove, and the size of groove is less than the size of groove.
Described projection is cambered surface away from the end face of one end of fixed way, and the arc top of cambered surface is away from fixed way, and the formation of the sidewall of cambered surface and projection is smoothly connected.
In sum, the beneficial effects of the utility model are: this lifting device simple in structure, principle is easy, can carry out repeated usage, manufacture, use cost is low, utilizes the structure arranging, I-beam section is clamped, make I-beam section stablize and can not come off in hoisting process, efficiency is high, prevents safety misadventure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark and corresponding parts title in accompanying drawing: 1-projection; 2-through hole; 3-fixed way; 4-groove; 5-groove.
the specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment:
As shown in Figure 1, a kind of lifting device that is exclusively used in I-beam section, comprise the fixed way 3 that is regular tetragonal body structure, on a wall of described fixed way 3, be provided with projection 1, projection 1 is welded as integral structure with fixed way 3, and the line between the center of the center of projection 1 and fixed way 3 is parallel with plumb bob vertical, on projection 1, be provided with through hole 2, the center superposition of the center of through hole 2 and projection 1, and the line of centers of through hole 2, perpendicular to the line between the center of projection 1 and the center of fixed way 3, is provided with anchor fitting on fixed way 3.Through hole 2 is the passages that pass as suspension hook, lifting device is fixed on crane, and in order to keep lifting center of gravity stable, so center that need to all parts is set on same plumb bob vertical, the length of projection 1 is less than the face size that is in contact with it fixed way 3, make the center of gravity of lifting device on fixed way 3, more stable during lifting.
Described anchor fitting comprises and is arranged on the groove 5 that is rectangular structure on fixed way 3, the center superposition of the center of groove 5 and fixed way 3, and the line of centers of groove 5 is parallel with the line of centers of through hole 2.The size of groove 5 is slightly larger than the size of the top board of I-beam section, and I-beam section can be extend in groove 5, utilizes the sidewall of groove 5 that I-beam section is blocked, and when lifting, can not come off.
Described fixed way 3 forms groove 4 away from one end indent of projection 1, and groove 4 is communicated with the both sides of fixed way 3, and the center of groove 4 is arranged on the line between the center of projection 1 and the center of fixed way 3; Described groove 4 is communicated with groove 5, and the size of groove 4 is less than the size of groove 5.Groove 4 is the placement passages as I-beam section web, the thickness of web is generally less than the width at I-beam section top, so the size setting of groove 4 is less than to the size of groove 5, utilizes the difference of size, I-beam section is clamped on groove 5, by suspension hook, passes through hole 2 and realize lifting.
Described projection 1 is cambered surface away from the end face of one end of fixed way 3, and the arc top of cambered surface is away from fixed way 3, and the formation of the sidewall of cambered surface and projection 1 is smoothly connected.End face by projection 1 is set to arc surface, has reduced the area of top end face, and when lifting, what suspension hook and projection 1 interfered may greatly reduce, and suspension hook can be extend in through hole 2 exactly.
Take aforesaid way, just can realize preferably the utility model.
