Abstract

In order to achieve assembling of certain aircraft engine fuel oil accessories, the invention provides a multi-degree-of-freedom aircraft engine fuel oil accessory support trolley. The support trolleycomprises a hydraulic lifting trolley and a support device; in the hydraulic lifting vehicle, a sliding frame is connected with a hydraulic cylinder through a supporting arm of the trolley body, a hydraulic trolley handle is arranged on the trolley body, a trolley chassis is arranged at the lower portion of the trolley body, and four universal wheels are arranged on the trolley chassis; in the support device, a main pump support is a semi-cylindrical shell, a strap and a clamp are arranged on the main pump support, and a rotating roller is arranged below the main pump support for driving themain pump support to rotate; the rotating roller is arranged on a pulley rotating support, and the pulley rotating support is of a plane structure; the lower portion of the pulley rotating support isconnected with a pitching frame through a bolt, and the pitching frame is connected with a sliding block through a connecting bolt; the sliding block is arranged on the sliding frame, a worm is arranged inside the sliding block, and the sliding block can slide on the sliding frame.

Description

technical field [0001] The invention relates to the replacement of fuel accessories of aero-engines, and in particular provides a bracket vehicle for changing the fuel accessories of aero-engines in the field. Background technique [0002] The accessory case of a certain type of aero-engine is placed below. When the main pump regulator and nozzle afterburner regulator fail and other large-scale fuel accessories are installed below, it needs to be replaced in the field. Due to the influence of the special position of the engine and the narrow space, it has been assembled by manual lifting, which may easily lead to problems such as scratches on the fuel accessory conduit and broken rubber rings. In order to solve this problem, the present invention designs a six-degree-of-freedom structure (that is, a rotation-bending-rotation structure) of the terminal "RBR", and applies a hydraulic rod to lift and manipulate the handle of the hydraulic car to realize the fuel accessories in ...
