Abstract
The invention discloses a crane lifting arm. The crane lifting arm comprises a fixed lifting hook, a lifting arm, an oil cylinder, a hinge, a support rack, and a motor, the fixed lifting hook is arranged on the lifting arm, the lifting arm and the support rack are connected through the hinge, the oil cylinder is arranged on the lifting arm, and the motor control the lifting arm to elevate and rotate. The motor is used to control the lifting arm to elevate, the rotation angle can also be controlled by the motor, and the rotation angle can reach 360 degrees. The crane lifting arm has the advantages of convenient installation, simple structure, low manufacture cost, and long service life.
Description
Technical field
The present invention is specifically related to a kind of crane arm.
Background technology
Along with the development of industry, increasing weight-lifting equipment is employed in production, and the arm on weight-lifting equipment is varied, and a lot of arm also needs to rotate.Suspension hook on general arm is all installed by wirerope-winding, the installation method not only troublesome poeration of this suspension hook, and complex structure, and cost is higher, inapplicable in the less demanding occasion of some sling heights.And the arm rotated has plenty of and pulls rotating disk to realize by common oil cylinder, the little and bad control of rotating speed of this method anglec of rotation; The electric control system of arm inside is complicated, is realized by motor, and difficulty of processing is large, and manufacturing cost is higher.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the invention provides a kind of crane arm.
Technical scheme: a kind of crane arm, comprise fixing suspension hook, arm, oil cylinder, hinge, bracing frame and electrical motor, described arm is provided with fixing suspension hook, is connected through the hinge between arm and bracing frame, described arm is equipped with oil cylinder, and described motor control boom luff rotates.
As optimization: described electrical motor is provided with electric cabinet and button box.
As optimization: described electrical motor is provided with safety guide rail and protects.
As optimization: described arm is also provided with removable suspension hook.
As optimization: be provided with sheath protection outside described oil cylinder.
Beneficial effect: arm of the present invention realizes controlling boom luff and the anglec of rotation by motor, and the anglec of rotation can reach 360 °, easy for installation, and structure is simple, and manufacturing cost is less, and service life is longer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment
As shown in Figure 1, a kind of crane arm, comprise fixing suspension hook 1, arm 2, oil cylinder 3, hinge 4, bracing frame 5 and electrical motor 6, described arm 2 is provided with fixing suspension hook 1, connected by hinge 4 between arm 2 and bracing frame 5, described arm 2 is equipped with oil cylinder 3, and described electrical motor 6 controls arm 2 lifting rotation.Electrical motor 6 is provided with electric cabinet 7 and button box 9.Electrical motor 6 is provided with safety guide rail 8 and protects.Arm 2 is also provided with removable suspension hook 10.Sheath protection is provided with outside oil cylinder 3.
For those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Arm of the present invention realizes controlling boom luff and the anglec of rotation by motor, and the anglec of rotation can reach 360 °, easy for installation, and structure is simple, and manufacturing cost is less, and service life is longer.
