Abstract

The utility model discloses a crawling crane used for lifting wind power equipment, which comprises a main arm support. The upper end of the main arm support is connected with an arm support head and a goose-head arm. The goose-head arm structure is as follows: the goose-head arm is provided with a pair of upper rods of which one ends are connected with a top supporting plate and a pair of lower rods of which one ends are connected with the top supporting plate, and the included angle between the two upper rods is of 25 DEG to 35 DEG; the included angle between the two lower rods is of 10 DEG to 20 DEG; the included angle between a plane where the upper rods are located and another plane where the lower rods are located is of 10 DEG to 30 DEG; the other ends of the upper rods and the lower rods are connected with a hinging lug which is matched with a lug plate on the arm support arm; the included angle between the plane where the hinging lug center of the ends of the upper/lower rods is located and the plane where the lower rods are located is of 45 DEG to 55 DEG; the top supporting plate is provided with a top pulley shaft; overall truss-like goose-heard arms formed by straight rods and inclined rods are connected between the upper rods, between the lower rods, and between the upper rods and the lower rods. The crawling crane has good stiffness and strength, increases hoisting capacity, is easy to lift equipment and to operate, and increases the working efficiency.

Description

Lifting wind power equipment crawler crane

Technical field

The utility model relates to a kind of hoisting crane, particularly a kind of lifting wind power equipment crawler crane.

Background technology

The crawler crane that is used to lift wind power equipment at present is to be hinged with the principal arm frame on main frame, and principal arm frame upper end is connected to the jib head, and the jib head is connected with the gooseneck boom arm of bracing frame form by the hinge ear structure.This jib structure causes hoisting capacity little, lifting instability, inconvenience during the lifting wind power equipment, operating difficulties.

Summary of the invention

The purpose of this utility model provides a kind of lifting wind power equipment crawler crane that improves hoisting capacity, stable, the good operation of lifting, overcomes the deficiencies in the prior art.

Lifting wind power equipment crawler crane of the present utility model, comprise and crawler crane mainframe pivotally attached principal arm frame, be connected to the jib head in the upper end of principal arm frame, the jib head joins by otic placode and gooseneck boom arm, it is characterized in that: described gooseneck boom arm configuration is: upper boom that end and top support plate join and the lower beam that joins of end and top support plate are one to one arranged one to one, and the angle that forms between two upper booms is 25 °～35 °; The angle that forms between two lower beams is 10 °～20 °; The angle that forms between the plane at the plane at upper boom place and lower beam place is 10 °～30 °; The otic placode that the other end of upper boom and lower beam is connected on hinge ear and the jib head matches; Angle between the plane at upper boom and hinge place, ear center, lower beam termination and the plane at lower beam place is 45 °～55 °; Top support plate upper support has the top pulleys axle; All be connected with straight-bar and brace formation integral truss-type gooseneck boom arm between the upper boom, between the lower beam and between upper boom and the lower beam.

Lifting wind power equipment crawler crane of the present utility model, the hinge ear of wherein said upper boom and lower beam termination are two plate hinge ears, and the otic placode on the jib head is a veneer, and inserting also mutually, bearing pin connects.

Lifting wind power equipment crawler crane of the present utility model compared with prior art has rigidity and intensity preferably, has improved hoisting capacity, and hanging device is easy, and good operation has improved operating efficiency.

Description of drawings

Fig. 1 is the structural representation of whole jib in the utility model specific embodiment;

Fig. 2 is that the master of gooseneck boom arm looks scheme drawing;

Fig. 3 is a schematic top plan view shown in Figure 2.

The specific embodiment

As shown in Figure 1, 2, 3: 1 is the principal arm frame, is connected with jib head 10 in the upper end of principal arm frame 1.

2 is the gooseneck boom arm, and the concrete structure of gooseneck boom arm 2 is: have and hold the upper boom 3 that welds with top support plate 7 one to one and hold the lower beam 4 that welds with top support plate 7 one to one.Shape C at an angle between two upper booms 3, the number of degrees of angle C are determined between 25 °～35 °.Form an angle B between two lower beams 4, the number of degrees of angle B are determined between 10 °～20 °.The angle A that forms between the plane at the plane at upper boom 3 places and lower beam 4 places is determined between 10 °～30 °.

Upper boom 3 other ends are welded with hinge ear 5, and the other end of lower beam 4 is welded with down hinge ear 6.Last hinge ear 5 and the otic placode that cuts with scissors on ear 6 and the jib head 10 down match.Last hinge ear 5 and following hinge ear 6 are two plates hinge ears, and the otic placode on the jib head 10 is a veneer, and insertion and bearing pin connect mutually.

All be welded with straight-bar and brace formation integral truss-type gooseneck boom arm 2 between the upper boom 3, between the lower beam 4 and between upper boom 3 and the lower beam 4.Shape D at an angle between the plane at upper boom 3 and lower beam 4 terminations hinge place, ear center and the plane at lower beam 4 places, the number of degrees of angle D are definite between 45 °～55 °; Support plate 7 upper supports in top have top pulleys axle 8, and bearing is connected between top pulleys 9 and the sheave shaft 8.
