A rotatable engine installation structure of an aerial work vehicle

Abstract

A rotatable engine mounting structure of an overhead working vehicle comprises an engine mounting base (6) rotatably connected with a get-on platform (3), the engine mounting base is a support body comprising a rectangular groove shape, an upper lug and a lower lug which are parallel to each other are arranged on the side face of the engine mounting base, a benchmark positioning hole is formed in a chassis of the get-on platform, the engine mounting base (6) is connected with the benchmark positioning hole in a pivot mode through a rotating pin shaft (4), and therefore the engine mounting base can rotate between the working position and the maintenance position. A rubber cushion block (11) is fixedly connected with the bottom of the engine mounting base (6). The structure further comprises a guide plate (15), the guide plate is fixedly connected with the chassis of the get-on platform (3), and the rubber cushion block (11) is supported on the guide plate. The mounting structure can achieve engine rotation in the narrow space, maintenance of the engine is facilitated, meanwhile, the problem of difficult screwing in and screwing out caused by large vibration between the engine and the platform and the machining error is solved, and the structure is simplified.

Description

technical field [0001] The invention relates to an installation structure, in particular to the technical field of an installation seat that can be used for a rotatable engine of an aerial work vehicle. Background technique [0002] Self-propelled aerial work vehicle is a special vehicle for transporting staff and equipment to the designated operating height for special operations. It is gradually replacing traditional scaffolding and is widely used in municipal construction, large-scale construction sites and construction facilities, maintenance of chemical equipment, Surface decoration projects such as ship repair, welding and painting work, such as for the 2010 Shanghai World Expo, built more than 100 venues of various types. The internal height and structural characteristics of these venues determine that aerial work vehicles are almost indispensable in their construction and use. [0003] The above-mentioned high-altitude operation vehicles generally use fuel power or ...

AI Technical Summary

Problems solved by technology

[0006] (1) Difficult maintenance problems caused by too small gap between the engine of the aerial work vehicle and the vertical plate;

[0007] (2) The excessive rotation of the engine after the rotary installation damages the hydraulic pump and engine accessories;

[0008] (3) After the engine is installed by rotation, the engine mount and the platform vibrate greatly;

[0009] (4) After the engine is installed by rotation, the engine casing is not properly processed, resulting in difficulty in installation
