Description
Technical field
The utility model relates to weight-lifting equipment, is specifically related to a kind of crane arm of weight-lifting equipment.
Background technology
At present, the crane arm that countries in the world use on the hoisting cranes such as automobile and engineering formula machinery, generally adopt the welding manner (as shown in Figure 1) of fillet welding and vertical position welding, weld seam is positioned at crane arm corner angle position, its common shortcoming is that weld nugget bearing capacity is large, anti-bending strength is poor, and insufficient strength is good.When crane arm rotates to the left and right, between the arm of more piece crane arm and arm, can transverse shakiness be produced owing to there is gap, cause crane arm unstable, destroy the overall performance of crane arm, crane arm even can be caused to fracture or machinery rollover.
Summary of the invention
The purpose of this utility model is the shortcoming existed for existing welding crane arm, provides a kind of high strength not snap crane arm.
Technical solution of the present utility model is: it comprises the parallel relative oblong left side board in left and right and right side board, the side long leg that left side board is relative with about right side board divides after subtend side plate curved bend folding, edge weld together, long leg relative about another divides and bends to obtuse angle, offside side plate direction, it also comprises two long limits oblong base plate parallel with the long limit of right side board with left side board, two long sides of base plate bend towards the obtuse angle, same lateral plates direction of base plate, the interior angle side part of obtuse angle, both sides bending is fitted in the outer plate surface of obtuse angle bending part of left side board and right side board respectively, the edge on two long limits of base plate is welded in the outer plate surface of left side board and right side board, left side board and right side board obtuse angle bending long side weld be connected on base plate towards left side board and right side board obtuse angle bending interior angle lateral plates on.
Technique effect of the present utility model is: it is little that it has weld nugget bearing capacity, and anti-bending strength is strong, the advantage that intensity is good.Because position while welding bearing capacity is little, can not situation be snapped, the bulk strength of arm can be improved, also can ensure the stability of crane arm when crane arm rotates transverse shakiness to the left and right, ensure that the overall performance of crane arm, crane arm can not be caused to fracture or machinery rollover.More be conducive to the normal operation of guarantee equipment and safety, reduce accident rate.
The application force of crane arm when hoisting weight occurs on the bending position of integrative-structure, do not occur in welded joints, decrease pulling force and pressure that when hoisting crane works, butt welded seam produces, weld seam only bears the pulling force of about 70%, this welding method reduces the technical requirements of butt welded seam processing, four (eight) intrinsic for original crane arm bar weld seams are reduced to three (five) bars (as Fig. 1), reduces productive costs.

Fig. 2 is the utility model embodiment three-dimensional structure diagram.
Detailed description of the invention
As shown in Figure 2, it comprises the parallel relative oblong left side board 1 in left and right and right side board 2, the side long leg that left side board 1 is relative with right side board about 2 divides after subtend side plate curved bend folding, edge weld together, long leg relative about another divides and bends to obtuse angle, offside side plate direction, it also comprises two long limits oblong base plate 3 parallel with the long limit of right side board 2 with left side board 1, two long sides of base plate 3 bend towards the obtuse angle, same lateral plates direction of base plate 3, the interior angle side part of obtuse angle, both sides bending is fitted in the outer plate surface of obtuse angle bending part of left side board 1 and right side board 2 respectively, the edge on two long limits of base plate 3 is welded in the outer plate surface of left side board 1 and right side board 2, left side board 1 and right side board 2 obtuse angle bending long side weld be connected on base plate 3 towards left side board 1 and right side board 2 obtuse angle bending interior angle lateral plates on.
Left side board 1 is identical with right side board 2 subtend arc bending part radian, and the angle be bent to form is 90 degree, and the edge position of left side board 1 and the bending of right side board 2 subtend arc is positioned at same plane.The edge side outwardly of left side board 1 and right side board 2 subtend arc bending weld together is provided with the groove 11,21 that can strengthen firm welding, and the weldering of groove 11,21 place is flat.
Left side board 1 is identical with the bending angle of right side board 2 obtuse angle bending part, and the bending angle that two long sides of base plate 3 bend towards obtuse angle, a direction is identical.
Two long legs that the bending angle that left side board 1 and right side board 2 obtuse angle bending long leg divide adds upper plate 3 divide obtuse angle, the same lateral plates direction bending angle towards base plate 3 to be 270 degree.
The long leg of left side board 1 and right side board 2 divides the angle to the bending of obtuse angle, offside side plate direction to be 90-135 degree, and base plate 3 is 135-180 degree towards obtuse angle, the same lateral plates direction bending angle of base plate 3.
The long leg of left side board 1 and right side board 2 divides the angle to the bending of obtuse angle, offside side plate direction to be 122 degree, and base plate 3 is 148 degree towards obtuse angle, the same lateral plates direction bending angle of base plate 3.
It belongs to a kind of light-duty circular arc crane arm, left side board 1 and right side board 2 obtuse angle bending long leg divide and to bend long leg with base plate 3 obtuse angle and divide to be superimposed and weld, the pressure acted in welded joints is made to convert pulling force to, add the thickness of crane arm lower compression position, improve the bending strength of crane arm, namely decrease materials and turn improve lifting performance.
Be characterized in:
1, crane arm is designed to left and right structure, welds in the middle of top after left side board 1 and right side board 2 bending, and simultaneously welding two sides is shaping to be designed to groove, both decreases weld seam, and turn improves efficiency;
