Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model comprises a hanging beam 1, wherein the left and right ends of the hanging beam 1 are hoisted by a steel wire rope 2; the lower parts of the hanging beams 1 are connected with clamps 3 through ropes 4; the clamp 3 comprises a middle vertical rod 301 connected with the rope 4, and a front vertical rod 302 and a rear vertical rod 303 are respectively arranged on the front side and the rear side of the middle vertical rod 301; the bottoms of the middle vertical rod 301 and the front vertical rod 302 as well as the bottoms of the middle vertical rod 301 and the rear vertical rod 303 are hinged through an upper bottom cross rod and a lower bottom cross rod which are parallel to each other, so that a front parallelogram structure and a rear parallelogram structure are formed; the tops of the middle vertical rod 301, the front vertical rod 302, the middle vertical rod 301 and the rear vertical rod 303 are hinged through a top cross rod 305 parallel to the low cross rod 304, and the top cross rod 305 can be detached.

In order to adapt to steel pipes with different lengths, a plurality of lifting hooks 5 are uniformly distributed at the lower end of the lifting beam 1, and a rope 4 above the clamp 3 is fixed on the lifting hooks 5.

For the convenience of hoisting, a hanging ring 306 is fixed at the upper end of the middle vertical rod 301, and the lower end of the rope 4 is fixed on the hanging ring 306.

In order to realize the dismantlement and the quick installation of top horizontal pole 305, the articulated shaft of the articulated point department of top horizontal pole 305 and well montant 301 can be demolishd, the one end of articulated shaft is provided with the arch, the other end cartridge has the spacer pin.

In order to increase friction, the outer edge surfaces of the middle vertical rod 301, the front vertical rod 302 and the rear vertical rod 303 are all wrapped with rubber layers.

In order to enhance the strength of the hanging beam 1, the hanging beam 1 is hoisted through a plurality of steel wire ropes 2.

When the utility model is used, firstly, the lifting hook 5 on the lifting beam 1 is properly selected according to the length of the steel pipe, and the rope 4 is connected with the lifting ring 306 on the clamp 3 through the lifting hook 5; by pulling out the top cross bar 305 at the point where the top cross bar 305 is hinged to the middle vertical bar 301, referring to fig. 2, the two top cross bars 305 on each clamp 3 can swing around the front vertical bar 302 or the rear vertical bar 303, and the top cross bar 305 can be rotated to one side so that it is no longer blocked between the middle vertical bar 301 and the front vertical bar 302 and between the middle vertical bar 301 and the rear vertical bar 303.

At the moment, the whole clamp 3 is placed on the ground, and the bottoms between the middle vertical rod 301, the front vertical rod 302 and the rear vertical rod 303 are hinged with two bottom cross rods which are vertically placed and are parallel to each other, so that the middle vertical rod 301, the front vertical rod 302 and the rear vertical rod 303 can be kept in a vertical state, and the steel pipes can be conveniently placed; when placing the steel pipe, lift the steel pipe to well montant 301 and preceding montant 302 through the manual work to and between well montant 301 and the back montant 303, through the dead weight of steel pipe, can keep the stability of whole device temporarily, make it not take place the slope, simultaneously in order to ensure safety, can keep wire rope 2 to have certain tensile force, thereby montant 301 keeps vertical state in the messenger, so, alright in order to better avoiding the device slope.

When the steel pipes are placed, the steel pipes are placed uniformly, namely, the same number of steel pipes are placed on the front side and the rear side of the middle vertical rod 301 as far as possible, so that the steel pipes are prevented from inclining during hoisting. The top cross bar 305 and the central vertical bar 301 may then be articulated again. Referring to fig. 3, the entire steel tube is now confined within the parallelogram formed by the central vertical rod 301, the front vertical rod 302 (the rear vertical rod 303), the top horizontal rod 305 and the bottom horizontal rod.

Afterwards alright lift by crane, because the gravity of steel pipe, this moment in montant 301 and preceding montant 302 (back montant 303), top horizontal pole 305, the parallelogram structure that the end horizontal pole is constituteed can take place to incline, see figure 4, the steel pipe can extrude end horizontal pole under the effect of dead weight this moment, thereby according to parallelogram structure's principle, then preceding montant 302 and well montant 301, and the interval between back montant 303 and the well montant 301 diminishes, press from both sides the steel pipe wherein, and because well montant 301, all be provided with the rubber layer on the outer fringe face of preceding montant 302 and back montant 303, consequently, can guarantee the stable centre gripping to the steel pipe.

After the steel pipe is conveyed to a destination, the whole device falls to the ground, and the parallelogram structure can be restored to the rectangular structure under the action of the gravity of the steel pipe, namely, the state of fig. 4 is restored to the state of fig. 3, and contrary to the step of placing the steel pipe, the steel pipe can be taken out after the top cross rod 305 is detached again.

This device is through montant 301 in setting up, preceding montant 302 (back montant 303), top horizontal pole 305, low horizontal pole 304 constitute parallelogram structure, can rely on the dead weight of steel pipe, thereby makes parallelogram structure warp and compresses tightly the steel pipe, has realized the chucking automatically, must extra action, can also be adapted to the steel pipe of different diameters simultaneously.

This device can keep the vertical state of preceding montant 302 or back montant 303 through setting up two low horizontal poles 304, conveniently carries out placing and taking out of steel pipe, guarantees that whole device can not take place the slope.

This device is through setting up a plurality of lifting hooks 5 in the bottom of hanging beam 1, can adjust the interval between two anchor clamps 3 about, conveniently is adapted to the steel pipe of different length.
