The Safe And Stable Research Of Forest Ecotype's Transporting Of Monorail Vehicle

The forest is the largest ecological of the earth.How to develop the construction of the forest industry system while protecting forest environment better is the course which needs resolving ceaselessly by our forest engineering investigator.Whereas the transportation inside the forest is one of the key contents of this kind of research tasks.At present,the domestic transportation inside the forest more or less destroy the forest zoology,also some of them have difficulty in span or laying and the fee is quite high.However,ecological monorail vehicle in forest invested in this text have the character of forest ecotype as well as convenient installation and low fees.At first,this paper summarizes development at home and broad for the monorail vehicle, and takes general summary on the investigation method of monorail vehicle technology and its load of pile.This text takes the M-600HS(8Ps) type forest multifunctional monorail transport facility manufactured by Korea MCK Mechanism Co.,Ltd.For example,and introduces into the main framework and spare parts of the facility.Also on this basis,the text takes deep analysis on the running institution and makes collecting blue print design and intension checking calculation,studies the track mesh mechanism,track support institution and the retroframe for monorail vehicle.Aiming at the character that the speed of forest monorail vehicle is relatively faster and the vehicles are always running on the ascent,decline and detour road,the text investigates the security and stability of the support institution and retro-frame for the monorail vehicle deeply.The text also investigates the intension of monorail vehicle knighthead and stability of the full support institution through analysis the force-received state when the monorail vehicle running on the ascent,decline and detour road during load and without load status.Using running monorail vehicle entity to take brake security experimentation and analysis the security problem for each brake form during different operation conditions when the monorail vehicle running on the three different tracks with load and without load.Adopting passing matrix method to establish calculation equation for the load of pile in vertical direction for the monorail vehicle.The pile of anti-sinking disc adopted in this article has the advantage of high load,convenient installation and low fees.The article analyses the relationship between the load of pile in the direction and the pile root.The investigation indicates that the carrying capacity has nice adaptability to the soil floor depth the column knocked into and change of the oil floor construction when the plinth depth is larger than 60cm,and the length of the column and the change of the soil floor have little impact on load of pile,whereas load of pile is more sensitive to the anti-sinking and change of column diameter dimension.Under vertical load function,the horizontal limit carrying capacity for the plinth is more sensitive to the length of the column,but less sensitive to the column diameter, and the impact of the anti-sinking on the horizontal function can be ignored.As the column length larger than 0.8m and during the function less than 100kN horizontal load,the horizontal displacement less than 3mm on the plinth earth surface.As the pile length is 0.8m,the earth surface displaced impact of the vertical load on the plinth under horizontal load function can be general ignored.Whereas as the pile length is 0.6m,the earth surface displaced impact of the vertical load on the plinth under horizontal load function is much distinct,and load in vertical direction has tendency to enhance horizontal displacement obviously.At last,the running track for the monorail vehicle with 400m length,around 145 relative height margin and 45 degree max gradient has been installed in the firefight village,six feng mountain of Gonghe town inside the Muling country,Heilongjiang Province.And this track has had test run and has got operation monorail vehicle entity.This is the first success of installation and test for the forest ecological monorail vehicle in our country.
