Balance weight installing support and wheel crane

Abstract

The invention relates to the technical field of engineering machinery, and discloses a balance weight installing support and a wheel crane. The balance weight installing support comprises a supportingbase (1) and an adjusting mechanism. An installing face for supporting a balance weight (2) is formed on the top of the supporting base (1). The bottom of the supporting base (1) is rotationally connected to a wheel crane frame (3). The adjusting mechanism can control the rotation of the supporting base (1) to adjust the installing face into a horizontal state. By means of the technical scheme, the balance weight installing support comprises the adjusting mechanism which can control the rotation of the supporting base to adjust the installing face for supporting the balance weight into the horizontal state all the time, the balance weight installing support is more accurately in location fit with a balance weight lifting mechanism subsequently, and therefore the balance weight installingefficiency is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a counterweight installation support and a wheeled crane. Background technique [0002] With the development of large-scale projects and changes in the construction terrain environment, wheeled cranes are more and more widely used in various engineering construction projects due to their advantages such as convenient transfer operations, flexible lifting operations, and strong adaptability to operating conditions. . As an important part of a wheeled crane, the weight of the counterweight has a great influence on the stability and lifting performance of the wheeled crane. Therefore, how to quickly install the counterweight has become a key point in the design of wheeled cranes. [0003] Such as figure 1 As shown, in the prior art, the wheeled crane support system 16 is first operated in place during the counterweight installation process, and at this time the enti...

Problems solved by technology

[0004] However, the current design of this fixed counterweight installation support is only suitable for the installation of the counterweight of wheeled cranes with relatively small tonnage. It will also increase accordingly, and the distance between the counterweight installation position and the supporting point of the support system is relatively far. In order to have enough space to place the counterweight, the front section of the wheeled crane chassis will be lengthened, which is easy to cause during the counterweight installation process. The deformation of the wheeled crane bracket, correspondingly, due to the deformation and deflection of the wheeled crane frame, it often leads to inaccurate positioning with the counterweight lifting mechanism. At this time, it is necessary to adjust the counterweight positioning seat on the counterweight installation bracket to make the counterweight installation efficient. lower
