Embodiment Construction
[0035] Specific embodiments of the present invention 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 invention, and are not intended to limit the present invention.
[0036] In the present invention, in the case of no contrary description, the used orientation words such as "up, down, left and right" usually refer to the up, down, left and right shown in the accompanying drawings; "inside and outside" Refers to the inside and outside of the outline of each part itself.
[0037] According to one aspect of the present invention, there is provided a counterweight installation assisting device, wherein the counterweight installation assisting device 300 includes a connecting portion 300a for connecting to the vehicle frame 100 of a wheeled crane and a connecting portion 300a for supporting the counterweight 200 . The support par...

The invention relates to the field of engineering machinery and discloses a counter weight mounting auxiliary device, a wheeled crane and a counter weight mounting method. The counter weight mountingauxiliary device (300) comprises a connecting part (300a) used for being connected to a frame (100) of the wheeled crane and a supporting part (300b) used for supporting a counter weight (200). The supporting part (300b) can be supported on the ground and connected to the frame (100) through the connecting part (300a). The counter weight mounting auxiliary device can be supported on the ground through the supporting part, and accordingly the temporarily-stored counter weight can be supported through the supporting part. On one hand, the supporting part is supported on the ground, so that the design space of the wheeled crane is not occupied; and on the other hand, the size of the supporting part is smaller than that of the counter weight, the needed site space is small, and adaptability toa construction site is more flexible; and therefore, the counter weight can be conveniently and rapidly mounted through the counter weight mounting auxiliary device.
Description
technical field [0001] The invention relates to construction machinery, in particular to a counterweight installation auxiliary device, a wheeled crane and a counterweight installation method. 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. . The counterweight has a great influence on the stability and lifting performance of the wheeled crane. [0003] To install the counterweight, first place the counterweight in place and then complete the installation by the counterweight lifting mechanism of the wheeled crane. In the prior art, according to the type and size of the wheeled crane and the size and weight of the counterweight, etc., the counterweight can be placed i...
