Problems solved by technology
[0004] At present, the counterweight connection method of crawler cranes is mostly a multi-block superimposed type. Several counterweights are fixed together by bolts, and the oil cylinder is fixed on the turntable through the pin shaft. This connection method has the disadvantage that the pin shaft is not easy to disassemble. The problem that the counterweight cannot be adjusted and external equipment such as oil cylinders are added

The invention provides a combined counter weight of a crawler crane. The combined counter weight of the crawler crane comprises a first counter weight at the front side and a second counter weight at the rear side; the upper end surface of the first counter weight is provided with a first assembling groove; the left part and the right part of the bottom surface of the first assembling groove are respectively provided with a first fixing device; a second assembling groove is formed at the middle part of the front end surface of the second counter weight; the left part and the right part of the bottom surface of the second assembling groove are respectively provided with a second fixing device. A left support plate and a second support plate of an installation frame are utilized for being respectively matched with the first fixing devices, and the two first fixing devices are respectively connected with the left support plate and the second support plate through pin shafts; the left support plate and the right support plate are matched with the second fixing devices of the second counter weight; the two second fixing devices are respectively connected with the left support plate and the right support plate through pin shafts; the first counter weight and the second counter weight are fixed on the installation frame. The combined counter weight of the crawler crane provided by the invention is simple in structure, is easy to detach, and does not need to fix the counter weight by an external mechanism.
Description
technical field [0001] The invention relates to a combined counterweight of a crawler crane. Background technique [0002] Crawler cranes are widely used in the construction of airports, docks, power plant construction, roads, railway roadbeds, etc. Because the weight of the weight of the weight of the weight of the weight of the weight of the weight of the weight of the weight of the weight of the weight of the weight is too large, the weight and other components are usually disassembled and transported during transportation. [0003] There is an installation frame at the rear of the turntable of crawler crane. The installation frame is generally a metal frame structure. The installation frame includes a left support plate and a right support plate. The left support plate and the right support plate are placed in parallel, and the left support plate and the right support plate are fixed. Support, the structure of the left support plate and the right support plate is the sam...
