Abstract
The utility model relates to a no-resistance carriage and flat car which is improved by a carriage and flat car of a resistant loading truck. A carriage board of the carriage vertical with relative speed of wind is necessarily under resistance which is in direct proportion to the cube of the relative speed of wind; the pressure differential resistance of the rear surface is in direct proportion to the square of the relative speed of wind. The utility model has the structure that a plane board vertical with the relative speed of wind is changed into a vertical net-shaped cartridge board, airflow passes through net holes in order to make the facade not generate resistance and make the back face not generate pressure differential resistance, and thus, the utility model plays the role of energy saving. A partition board is closed when power-shaped objects is loaded; two slide rings and the partition board sheathed on the slide rings are arranged on the joint position of the net-shaped cartridge board and a side cartridge board. Thus, the three cartridge boards are all arbitrarily pushed up or down.
Description
Affiliated technical field
The utility model relates to a kind of improvement, and resistance load-carrying lorry body and train open-top car are arranged is non-resistance load-carrying lorry body and train open-top car.
Background technology
The first row train of own first autotruck and grandson's Shi Difen invention rises, and its railway carriage is made up of the surface plate of four settings.Under the low speed before many decades, its power consumption still belongs to limited, constantly increases at express highway, and train constantly raises speed, railway carriage constantly extends, under the situation that boxboard constantly increases, and the incompatible modern needs of resistant railway carriage.The first, the automobile speed per hour increases to 120 kilometers by 60 kilometers, by W=1/2 ρ SV
3(ρ=density of air, S=are obstructed area, V=relative wind velocity) as can be known, resistance W and speed V cube are directly proportional, promptly speed increases by 1 times, resistance then increases by 8 times.In addition,, form vortex, thereby produce pressure drag, square being directly proportional of its resistance and speed at the back side of the plane boxboard vertical with wind speed.The second, according to the rule of wind, the height of establishing obstacle is h, forms a turbulent region behind obstacle, the turbulent region with after prolong and weaken, after 10h, wind speed is reduced to former wind speed.The existing long 8m of railway carriage, wide 2.3m, the bogie of high 0.8m.If be 1m at the bottom of the railway carriage to the operator's compartment top, can be being divided into four gradients in the case, then the wind speed at three of rearing-box plate gradient places becomes former wind speed, and the 4th gradient place is kept to slightly.When 120 kilometers of speed per hours and no-load, only (area is 1.38m for its rearing-box plate of 3/4
2) the driving engine per second need make 322763 joules merit, begins to overcome its resistance (pressure drag is still disregarded interior).If with computation of areaBZ, this car area that always is obstructed is about 6m
2, and rearing-box plate (1.845m
2) area that is obstructed accounts for 30% of the area that always is obstructed.During train open-top car no-load, 3/5 place of its rearing-box plate is former wind speed, and 2/5 place has slightly and weakens, if run for 80 kilometers with speed per hour, only the every sq m per second of rearing-box plate driving engine need be made 69281 joules merit, begins to overcome this resistance (pressure drag is still disregarded interior).The rearing-box plate that have only bogie vertical with relative wind velocity and the front and back boxboard of open-top car in railway carriage are meaningless for overcoming that resistance than boxboard consumes energy, and this kind power consumption is soluble.
Summary of the invention
The purpose of this utility model provides a kind of vertical net structure boxboard that does not produce resistance, air communication is crossed mesh, the front does not produce resistance, the back side does not produce pressure drag, the inferior open-top car of particularly annual 300000 trains of transporting the coal in the North to the South, when empty wagons north is returned, become the unresisted from the beginning to the end flat truck of row, thereby play energy-conservation effect.Vertical net structure, owing to be vertical, its stress is greater than the stress of existing boxboard on anti-extrusion.
The specific embodiment
The purpose of this utility model is achieved in that the boxboard vertical with relative wind velocity is the net like boxboard of gridiron.Four frames of grid constitute by Siping City's face thin plate is vertical.Thin plate has certain width, to strengthen the intensity of stress.When delivering thin, little and powder, before netted boxboard, close, remove dividing plate when sky returns, make air communication cross mesh with dividing plate.Dispose two slip rings at netted boxboard with combining of side boxboard, dividing plate can move on slip ring.Slip ring is two sections, can close and can divide, and boxboard is pushed to then and closed, and puts down then and divides.So, no matter adorn and unload, three boxboards all can be pushed to arbitrarily or be put down, and are same with existing boxboard.Open-top car then is a set collar.Dividing plate can be simple gate, also can be two-door.
Accompanying drawing proves
Concrete structure of the present utility model and enforcement thereof are provided by figure below.
Fig. 1 is vertical netted boxboard scheme drawing.(1) be three-dimensional grid, the width thin and thick of grid steel bar is decided by the purpose of using.(2) be dividing plate.
Fig. 2 is the birds-eye view of slip ring.The integral body of slip ring is a semi-ring, and 1/4 of semi-ring is welded on (3) on the boxboard of side, and 3/4 is welded on the band steel of netted boxboard inboard (4).Dividing plate has two holes, and two slip rings are enclosed within on two holes, and dividing plate (2) can move on slip ring.No matter the no-load of carrying is arranged, and three boxboards all can arbitrarily be pushed to or be put down.(5) be the last base of netted boxboard.(6) be the side boxboard.
Claims (3)
1, a kind of non-resistance railway carriage becomes unresisted netted boxboard to the have resistance plane boxboard vertical with relative wind velocity of load-carrying lorry and train open-top car, it is characterized in that netted for vertical, to strengthen anti-extrusion stress.
2,, it is characterized in that having a dividing plate that is used to load thin, little or powder according to the described non-resistance railway carriage of claim 1.
3, according to the described non-resistance railway carriage of claim 1, it is characterized in that two slip rings being arranged in the junction of netted boxboard and side boxboard, slip ring is two sections a semi-ring, dividing plate has two holes, is enclosed within on two slip rings.
