Description

Technical Field

[0001] The utility model belongs to the field of cranes, in particular to an omnidirectional rotating crane. Background Art

[0002] Generally, commonly used cranes usually use a hydraulic cylinder telescopic support to rotate the boom. Due to the limited telescopic length of the hydraulic cylinder, the rotation angle of the boom is very limited, the working range is relatively small, and it cannot be applied to all work occasions.

[0003] As shown in Chinese patent CN204400484U, a manual hydraulic rotary crane is disclosed, comprising a vertical arm, a boom, and a manual hydraulic cylinder. The vertical arm comprises a fixed sleeve at its bottom and a rotating arm connected thereto and rotatable about it. The upper end of the rotating arm is hinged to the horizontal boom, and the front end of the boom is connected to a hook. The manual hydraulic cylinder comprises a telescopic cylinder body, connecting pipelines, and a hand pump. The telescopic cylinder body is supported between the vertical arm and the boom, with one end hinged to the rotating arm and the other end hinged to the boom. This patent only uses a single telescopic cylinder body, which greatly limits the boom's range of motion, hindering operational efficiency. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an omnidirectional rotating crane capable of expanding the rotation angle and increasing the range of movement.

[0005] The technical solution adopted by the utility model to solve the technical problem is:

[0006] The utility model provides an omnidirectional rotating crane, comprising: a base, a boom, a connecting piece, a first telescopic piece, and a second telescopic piece; one end of the boom is hinged to the base; both ends of the connecting piece have a first hinge point and a second hinge point, the middle part of the connecting piece has a third hinge point, and the connecting piece is hinged to the base through the first hinge point; the fixed end of the first telescopic piece is connected to the base, and the movable end of the first telescopic piece is connected to the second hinge point of the connecting piece; the fixed end of the second telescopic piece is connected to the third hinge point of the connecting piece, and the movable end of the second telescopic piece is connected to the boom.

[0007] Furthermore, the second telescopic member is connected to the boom via a lug plate.

[0008] Furthermore, the first telescopic member and the second telescopic member are hydraulic cylinders, pneumatic cylinders or electric push rods.

[0009] Furthermore, the connecting member has a first connecting plate, a second connecting plate and a third connecting plate connected in sequence, the angle between the first connecting plate and the second connecting plate is 100° to 160°, and the angle between the second connecting plate and the third connecting plate is 100° to 160°.

[0010] Furthermore, the first hinge point is provided at the end of the first connecting plate, and the second hinge point is provided at the end of the third connecting plate.

[0011] The advantages and positive effects of the utility model are:

[0012] The utility model uses two telescopic parts and a connecting part. After the first telescopic part is extended into place, the supporting effect of the connecting part is utilized to enable the second telescopic part on the connecting part to continue to extend on the basis of the first telescopic part, thereby realizing two-stage telescopic extension, effectively expanding the rotation angle, increasing the range of movement, being beneficial to the operation of the crane in various occasions, and improving work efficiency.
