Description

A kind of round steel pipe hoisting appliance

Technical field

The utility model relates to a kind of device that hoisting force is directly acted on the load surface, specifically, relates to a kind of hoisting appliance for round steel pipe.

Background technology

In daily production process, the staff often need to lift operation to round steel pipe, but because steel tube section is circular, therefore is difficult for finding suitable suspension centre.

The lifting mode that adopts at present mainly contains two kinds, and the first is used hanging belt binding lifting, and shortcoming is the steel pipe below need to be paved, with convenient binding hanging belt, after steel pipe was in place, hanging belt also was not easy to unload simultaneously, operate cumbersomely, waste unnecessary man-hour; It two is to use the suspension hook lifting at steel pipe two ends, and shortcoming is when the steel pipe tube wall is thinner, only is hooked in the upper wall position of steel pipe inboard due to suspension hook, and the deadweight of steel pipe can make the thin-walled tube cross section that the distortion of unrepairable occurs.

The utility model content

To be solved in the utility model is the technical matters of existing round steel pipe lifting inconvenience, and a kind of round steel pipe hoisting appliance is provided, and can improve work efficiency when guaranteeing working accuracy.

In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:

A kind of round steel pipe hoisting appliance, consisted of by the hoisting appliance body, described hoisting appliance body comprises a S shape plate and the 2nd S shape plate arranged in a crossed manner mutually, a described S shape plate be connected the 2nd S shape plate and connect by bearing pin at the point of crossing place, the top of a described S shape plate and described the 2nd S shape plate is respectively arranged with lifting hole(eyelet).

An a described S shape plate and S shape board member that be arranged identical by two forms, and the clamping plate that arrange by the interval between two described S shape board members connect, and described the 2nd S shape plate is arranged in two spaces between a described S shape board member.

The thickness of described clamping plate is greater than the thickness 1mm ~ 2mm of described the 2nd S shape plate.

The bottom arc diameter of a described S shape plate and described the 2nd S shape plate is 500mm.

The width of a described S shape plate and described the 2nd S shape plate is 80mm ~ 100mm.

The beneficial effects of the utility model are:

(1) the latter half of a S shape plate of the present utility model and the 2nd S shape plate consists of more than half circular arc, anchor ear that can be whole is outside at round steel pipe, make round steel pipe stressed evenly in when lifting, not only Hoisting Security is stable, even and also can not deform than the steel pipe of thin pipe wall.

(2) a S shape plate of the present utility model and the 2nd S shape plate are arranged in a crossed manner, be similar to scissor design and make a S shape plate and the 2nd S shape plate folding with convenience, can be very easy to and carry out Assembly ﹠Disassembly easily on round steel pipe, operating efficiency is higher.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As shown in Figure 1, the present embodiment has disclosed a kind of round steel pipe hoisting appliance, and mainly by a S shape plate 1 with the 2nd S shape plate 2 is mutually arranged in a crossed manner consists of, a S shape plate 1 and the 2nd S shape plate 2 connect by bearing pin 3 at the point of crossing place.The top of the one S shape plate 1 and the 2nd S shape plate 2 is provided with respectively lifting hole(eyelet) 4 symmetrically, and lifting hole(eyelet) 4 can be connected with hoist cable 7 by buckle.

During making, the diameter range that lifts by crane at first as required round steel pipe 5 is determined to be generally 500mm by the bottom arc diameter of a S shape plate 1 and the 2nd S shape plate 2, like this hoisting appliance round steel pipe 5 of all diameters less than 500mm of can slinging.Consider in addition and take into account economical with materials and safety two aspects, the width of a S shape plate 1 and the 2nd S shape plate 2 is got 80mm ~ 100mm and is advisable.

The one S shape plate 1 is comprised of two identical S shape board members, two S shape board members are parallel to each other, and two S shape board members 11 pass through clamping plate 12 weld togethers of three block gaps, and clamping plate 12 should be avoided the position of S shape plate 1 middle part installation the 2nd a S shape plate 2 and bearing pin 3.

The 2nd S shape plate 2 is plugged in space between two S shape board members of a S shape plate 1, is connected with a S shape plate 1 by bearing pin 3.In order to make the 2nd S shape plate 2 can be between two S shape board members of a S shape plate 1 effectively movable, the gap between two S shape board members, namely the thickness of clamping plate 12 should be slightly larger than the thickness of the 2nd S shape plate 2, generally is advisable with 1mm ~ 2mm.Certainly, a S shape plate 1 also can only be made of single-skin panel, this moment and the 2nd S shape plate 2 cross-lappings.

Bearing pin 3 needs to adopt fixation after installing, in order to avoid long-time frequent the use caused it to come off and safety misadventure occurs.General adoptable method has two kinds, and a kind of is with bearing pin 3 and S shape plate 1 welding; Another kind is to overlap respectively top external diameter at the two ends of bearing pin 3 greater than the plectane of bearing pin 3 diameter 5mm ~ 10mm and fixing, and the method is more convenient for safeguarding with respect to first method.

As shown in Figures 2 and 3, when this hoisting appliance is about to drop down onto when needing the round steel pipe of lifting 5 upper end, strut round about respectively the first half of a S shape plate 1 and the 2nd S shape plate 2, the latter half of a S shape plate 1 and the 2nd S shape plate 2 will be opened.After circular arc that a S shape plate 1 and the 2nd S shape plate 2 the latter halfs consist of is enclosed within round steel pipe 5 outsides, directly lifting, the lifting power that crane makes progress and the downward gravity of round steel pipe 5 cooperatively interact, will make arc structure that a S shape plate 1 and the 2nd S shape plate 2 the latter halfs consist of tightly hold tightly round steel pipe 5 locked.After hoisted in position, make to strut in the same way a S shape plate 1 and the 2nd S shape plate 2, just can conveniently this hoisting appliance be unloaded.

Generally, can use single the hoisting appliance round steel pipe 5 of slinging, Hoisting Position is the center of gravity of round steel pipe 5.Comparatively thick and heavy round steel pipe 5 needs to use two these hoisting appliances to lift, use two hoisting cranes to connect respectively this hoisting appliance, or by an equalizing bar 6, connect respectively hoist cable 7 at two ends, hoist cable 7 is connected on lifting hole(eyelet) 4 by buckle again, thereby make the direction of lifting power perpendicular to the ground, as shown in Figure 4.

Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, within these all belong to protection domain of the present utility model.
