Embodiment Construction

[0028] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0029] Such as Figure 1 to Figure 2 As shown, according to one aspect of the present disclosure, a jib counterweight mechanism is provided, including a counterweight 6 arranged on the jib turntable 3, wherein the counterweight 6 is movably arranged on the jib turntable 3, and the counterweight The mechanism also includes a transmission device, through which the counterweight 6 is connected to the boom 1 of the crane, so as to adjust the position of the center of gravity of the counterweight 6 relative to the turntable 3 through the movement of the boom 1 .

[0030] With the elongation of the jib and the increase of the weight, the tipping moment of the cran...

Abstract

The invention relates to a cantilever crane counterweight mechanism and a crane. The cantilever crane counterweight mechanism comprises a counterweight (6) arranged on a cantilever crane rotary table (3). The counterweight (6) is movably arranged on the cantilever crane rotary table (3). The cantilever crane counterweight mechanism further comprises a transmission device. The counterweight (6) is connected to a suspension arm (1) of the crane through the transmission device, so that the position of the gravity center of the counterweight (6) relative to the cantilever crane rotary table (3) is adjusted through the movement of the suspension arm (1). With the increasing of the displacement of the gravity center, the anti-tipping torque of the crane can be gradually improved, so that the elevating capacity of the suspension arm is improved under the condition that the stability and safety of the suspension arm are guaranteed.

Description

technical field [0001] The present disclosure relates to the field of cranes, in particular, to a jib counterweight mechanism and a crane using the mechanism. Background technique [0002] The counterweight is an important part of the truck crane, which mainly plays the role of increasing the stabilizing moment and improving the lifting capacity. The further back the counterweight is in the working state, the greater the stabilizing moment and the higher the lifting capacity; in the prior art, the counterweight is fixedly installed on the turntable, and the installation position is generally the rearmost under the axle load of the rear axle that meets the requirements of national regulations. position. Although this method meets the requirements of national regulations, it does not provide sufficient stabilizing torque. Contents of the invention [0003] The object of the present disclosure is to provide a jib counterweight mechanism capable of adjusting the center of gr...
