Embodiment Construction
[0040] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0041] The specific embodiments of the present invention are for the convenience of further description of the concept of the present invention, the technical problems to be solved, the technical features constituting the technical solution and the technical effects brought about. It should be noted that the description of these embodiments does not constitute a limitation of the present invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0042] Due to the many hoisting performance conditions of super-large-tonnage cranes, the weight of a single piece of counterweight is small, and the number of combinations is large. When the overall height of the counterweight exceeds a ce...

The invention relates to a combined counterweight mounting structure and a mobile crane. The combined counterweight mounting structure comprises a counterweight support on which counterweights can be placed, and a locking device for locking the counterweights on the counterweight support, wherein the counterweight support comprises an auxiliary counterweight support and a movable positioning support hinged with the auxiliary counterweight support, and the auxiliary counterweight support is provided with a fixed positioning block; the movable positioning support is provided with a movable positioning block, and is matched with the fixed positioning block by rotating the movable positioning support to position the counterweights. According to the combined counterweight mounting structure, a single-row counterweight arrangement mode and a side-by-side counterweight arrangement mode can be switched, and the overall height of center of gravity of the counterweight can be reduced, and the overall stability, reliability and safety of the use process of the counterweight can be improved under the condition of unchanging a distance between the center of gravity and the center of rotation.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a combined balance weight installation structure and a crane. Background technique [0002] In the field of construction machinery, cranes are commonly used hoisting construction machinery equipment, which mainly include rail cranes and mobile cranes. Among them, mobile cranes include all-terrain cranes and tire cranes. Mobile cranes are widely used in engineering construction due to their advantages such as good passability, good maneuverability, fast transfer, and fast driving speed. However, the mobile crane is limited by its own weight, and the hoisting weight is small. In order to improve the stability of the mobile crane during work, a counterweight is usually assembled on the mobile crane. [0003] The counterweight is the main structural component of the mobile crane, and the weight of the counterweight has a great influence on the stability and lifting performance o...
