Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0025] As a first aspect of the present invention, there is provided a supporting device, which can be used to support the outrigger of a crane, in particular, connected to the vertical oil cylinder of the outrigger of the crane. Of course, the supporting device can also be used to support other supporting parts subject to deflection and deformation.

[0026] like Figures 3 to 5 As shown, the supporting device includes: a lower support 20 , an upper support 10 and an elastic element 30 . Wherein, the lower support 20 includes a support portion 21 ; the upper support 10 is movably supported on the lower support 20 . One end of the elastic element 30 is connected to the side wall of the support portion 21 , and the other end of the elastic element ...

Abstract

Disclosed are a supporting device and cranes comprising the supporting device. The supporting device comprises a lower supporting base (20), an upper supporting base (10), and an elastic element (30), wherein the lower supporting base (20) comprises a supporting portion (21); the upper supporting base (10) is movably supported on the lower supporting base (20); and one end of the elastic element (30) is connected to the supporting portion (21) and the other end of the elastic element (30) is connected to the upper supporting base (10). In the present invention the upper supporting base is movably supported on the lower supporting base, when both forces in a vertical and horizontal direction are applied to a part to be supported due to a flexural deformation, the upper supporting base is pushed to horizontally move relative to the lower supporting base under the action of the force in the horizontal direction such that the part to be supported returns to a state in which the part to be supported is only subjected to the force in the vertical direction, so that the part to be supported can no longer generate flexural deformation and the service life of the part to be supported is prolonged.

Description

technical field [0001] The invention relates to the field of cranes, and more specifically, to a supporting device and a crane. Background technique [0002] Engineering mechanisms (such as cranes) in the prior art have outriggers and the like, and support devices need to be installed on the outriggers when in use. Wherein, one end of the outrigger is connected with the vehicle frame of the crane, the other end is provided with a vertical oil cylinder, and a supporting device is installed at the free end of the vertical oil cylinder. When the outrigger needs to be supported, the vertical oil cylinder is driven to move downward, thereby supporting the entire vehicle frame to the ground through the supporting device. [0003] like Figure 1 to Figure 2 As shown, the front end of the piston rod of the vertical oil cylinder 80 of the outrigger of the crane is a hemispherical head, and a groove matching the hemispherical head is provided on the supporting device 100, which is us...
