Description
Technical field
The invention belongs to technical field of jacks, it is specifically related to a kind of Mechanical type airplane screw block.
Background technology
One kind equipments such as main equipment such as aircraft, in jacking process, its loading characteristic is: jacking stroke is long. common screw block requires that the difference of altitude from the state height for subsequent use of screw block to jacking terminal reaches 1500mm～3500mm, wherein 1200mm～3200mm is idle path, useful load stroke is only about 300mm, the weight of load reaches 10 tons～30 tons, and there is bigger side force, it is about the 10% of vertical load, this volume just determining this kind equipment is generally huger, own wt is also big, impel the propulsion source of screw block lifting to select manually or electric hydaulic mode at present more, hydraulic driving mode has easy to operate, the operation Impact direction of manual operation bar is easy to adjustment, the advantage operated steadily. but also deposit many shortcomings: easily leakage of oil, poor in self, complex structure, that F.F. enters rising or falling speed with work is identical, cause lift velocity very slow, single job often needs 20 minutes～50 minutes, the motion pattern of the general body of large-scale screw block is three supporting-point roller traveling modes, not having two-dimensional motion, top alignment is best to be not easy by force operation.
Common hydraulic jack to the lifting of the big range structure formation adopting combined nesting Multi-stage cylinder more, the fluid that multicomputer closes hydraulic cylinder inside bears same pressure, also have the diameter ratio of effect of increasing hydro-cylinder when unavoidable problem is idle path in a structure bigger, so needing fuel delivery big, if adopting the hydro-cylinder jacking 3000mm of manual mode, it is generally required to the time of about 40 minutes, this makes troubles to field condition aircraft maintenance, moreover hydraulic efficiency system there will be leakage of oil unavoidably, this is concerning very unfavorable the aircraft jacking needing long period (service intervals of several hours to tens days).
The movement of common heavy screw block body adopts three-wheel to move more, and front-wheel can change working direction, and being unfavorable for owing to aircraft bottom space is little moving around regulates central position, top, so just making top alignment aircraft carrying focus point become not to be very convenient. Owing to the top of aircraft screw block vertex is from 3000mm～5500mm, scene often needs repeatedly repeatedly to be directed at and can complete, and this makes troubles to actual use, also can affect device security.
Hydraulic jack loading piston bar can not bear side force, its mechanical interlock mechanism has two big shortcomings, one is want manually to adjust at any time in F.F. process, so its operation is it is generally required to two people operate, two is that nut is connected with next stage and can only transmit side force by frictional force, has potential safety hazard.
