Cantilever crane and drainage vehicle

Abstract

The invention discloses a cantilever crane system and a drainage vehicle, relates to the field of flood disaster emergency rescue equipment, and aims to improve the structure of the cantilever crane system. The boom system comprises a rotary platform, a connecting frame assembly, a boom assembly and a water pump. The revolving platform is configured to provide support; the revolving platform is configured to revolve relative to its own rotation axis. The connecting frame assembly is rotatably installed on the rotary platform. The arm frame assembly is rotatably installed on the connecting frame assembly so as to change the inclination angle of the arm frame assembly. The water pump is installed at the tail end of the boom assembly. According to the cantilever crane system provided by the technical scheme, the overall rotation of the cantilever crane assembly is realized through the connecting frame assembly, so that the working position of the water pump mounted on the cantilever crane assembly is changed, and the drainage requirements of different places are met.

Description

technical field [0001] The invention relates to the field of flood disaster emergency rescue equipment, in particular to a boom and a drainage vehicle. Background technique [0002] Due to the imperfect urban drainage system in our country, when heavy or continuous precipitation exceeds the local drainage capacity, it is very common for low-lying areas in the city to accumulate water. Urban waterlogging occurs in a wide range and lasts for a long time. The frequent urban waterlogging in recent years has brought huge losses to the life and property of urban residents, and also seriously affected the normal order of economy and society. Urban waterlogging emergency rescue is mainly to carry out drainage operations. As a supplement to the fixed drainage pumping station, the emergency drainage vehicle is suitable for drainage of accumulated water in places such as urban roads, overpasses, underpasses and tunnels. Among them, the boom-type emergency drainage vehicle is widely ...

AI Technical Summary

Problems solved by technology

[0004] The inventors have found that there are at least the following problems in the prior art: in the related art, the drainage mechanism is slidably connected to the support frame through a sliding mechanism. When it is necessary to move the drainage mechanism, there are many operating steps, and the operation needs to be slid first and then changed, which makes the operation complicated. The boom system has a simple structure and limited working range
