Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] In the present invention and the embodiments of the present invention, the construction machine is a crane. The movement of the center of gravity of the counterweight 1 mentioned in the following description refers to the change of the center of gravity of the counterweight 1 relative to the position of the crane, and the change of the center of gravity of the counterweight 1 can cause the change of the anti-overturning moment of the crane.

[0023] Such as figure 2 and image 3 As shown, the embodiment of the present invention provides a counterweight mechanism for construction machinery. The construction machine includes a turntable and a winch system 10 connected with the turntabl...

Abstract

The invention provides a balance weight mechanism used in an engineering machine which includes a rotating bench and a winding system connected thereto. The balance weight mechanism comprises: two balance weights which are arranged symmetrically relative to the width direction of the winding system and are respectively pivotedly connected to the winding system; and a driving apparatus, of which one end is pivotedly connected to the winding system and the other end is respectively connected to the two balance weights drivingly for driving the balance weights to rotate within the planar surface relative to the winding system. The balance weight mechanism can solve the problem of a poor whole stability in the prior art.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a counterweight mechanism for construction machinery. Background technique [0002] At present, most of the counterweights of cranes are fixed counterweights. The center of gravity of such counterweights is stationary relative to the turntable and the distance from the center of rotation cannot be changed. The distance from the center of gravity of the counterweight to the center of gyration affects the stability of the vehicle. The length of the rear suspension when the vehicle is running limits the distance from the center of mass of the counterweight to the center of rotation. Make the counterweight movable, and move the counterweight in a direction away from the center of slewing when the vehicle is working, which can effectively increase the anti-tipping moment and improve the stability of the vehicle. [0003] The prior art patent 201110181113 provides a co...
