Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is top view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 1, a kind of cylinder rod-like articles that is used for welds alignment device of slinging, and comprises a portal frame 1, is provided with clamping device in portal frame inside.
As shown in Figure 1, this clamping device comprises a boatswain chair 21, and plate 22 hinged one is embraced to downward-extension respectively in the two ends on boatswain chair base, embraces a plate bottom and bends inwards and form handgrip 221, two handgrip and be oppositely arranged.Be provided with rotating threaded shaft 23 between two armfuls of plates 22, the middle part of rotating threaded shaft is rotating handles 231.This rotating threaded shaft 23 is positive and negative leading screw, and namely the screw thread of rotating handles 231 both sides is arranged on the contrary, and the two ends of described rotating threaded shaft are each passed through embraces plate and and passes through threaded engagement between armful plate.Known shown in 1 by reference to the accompanying drawings, two armfuls of plates 22 can be furthered or push away when positive and negative rotation rotating threaded shaft 23.
As shown in Figure 1, lowering or hoisting gear is provided with between the crossbeam 11 of boatswain chair 21 and portal frame.
In the present embodiment, as shown in Figure 1, lowering or hoisting gear preferably adopts chain block 3, adopts chain block 3 that the mode manually pulled can be adopted to rise to lowering or hoisting gear neatly or decline.Certainly, lowering or hoisting gear also can adopt oil cylinder, motor etc., but chain block is easier when making this device relative to above-mentioned lowering or hoisting gear, and without the need to carrying out supply of electric power.
As shown in Figure 1, when operated, put down clamping device 2, two handgrips 221 are placed in the both sides of cylindrical bar 4, rotate rotating threaded shaft 23 and furthered by two armfuls of plates 22, the surface of two handgrips 221 contacts with cylindrical bar 4, because handgrip 221 is in the state of bending inwards, now upwards rise clamping device two handgrip 221 cylindrical bar 4 promptly to be mentioned, without the need to first being paved by cylindrical bar 4, this especially seems convenient when slinging electric pole operation.If the length of cylindrical bar 4 is longer, the device provided in multiple the present embodiment can be adopted to sling to cylindrical bar.After two sections of cylindrical bars are all lifted, the height of adjustment two sections of cylindrical bars, makes it highly consistent, and manually moves left and right clamping device the welding end centering of cylindrical bar can be welded.
As shown in Figure 1, for making handgrip 221 contact with the bottom of cylindrical bar 4, during making as far as possible, the floor design of handgrip 221 is plane, simultaneously for increasing the frictional force of handgrip and cylindrical object, is provided with frictional layer 2211 at the inner surface of handgrip, during making, frictional layer can select rubber or cork to make.
In above-mentioned description, when lowering or hoisting gear 2 and portal frame crossbeam 11 are for being flexible coupling, lowering or hoisting gear can move freely left and right, as lowering or hoisting gear 2 and portal frame crossbeam 11 be Hard link time, lowering or hoisting gear 2 moves left and right and can seem abnormal difficult.For solving high-tech problem, as shown in accompanying drawing 1 and accompanying drawing 2, portal frame crossbeam 11 is provided with the notch 111 along crossbeam trend, horizontal screw lead 5 is provided with above notch 11, the two ends of horizontal screw lead 5 and the two ends of crossbeam 11 support fixing by bearing (attached not shown bearing), horizontal screw lead 5 is provided with nut 6.Meanwhile, as shown in Figure 1, nut 6 and the lifting connection filled between 2 are connected by connecting rod 7, and this connecting rod 7 is through crossbeam notch 111, and its two ends are connected with nut, lowering or hoisting gear respectively.
For convenience of the rotation of horizontal screw lead 5, as shown in Figure 2, the end of portal frame crossbeam 11 is passed in one end of horizontal screw lead 5, and is provided with rotating handles 7 at the external part of horizontal screw lead.
During use, can make the positive and negative rotation of horizontal screw lead 5 by rotating rotating handles 7, thus drive nut 6 left and right displacement, nut 6 drives lowering or hoisting gear 2 to move left and right, chain block 3 drives lowering or hoisting gear 2 to move up and down, and realizes the coaxial alignment of two sections of cylindrical object welding ends.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalents thereof.
