Technical field
The present invention relates to a kind of mountain region conveying arrangement of easy rail mounted, having particularly related to one can with a varied topography, realizes Material Transportation and carry the Simple rail type conveying arrangement that other automatically working machineries (such as automatic medicine spraying device etc.) work between the mountain region that the gradient is larger.
Background technology
At present, attempting solving in the problem of High angle abrupt slope, mountain region transport difficult, mainly contain crawler type, aerial rope way formula and rail mounted three kinds, crawler type can cause certain destruction to the vegetation in mountain region in operational process, is unfavorable for the protection of mountain environment.Aerial rope way formula and rail mounted all need the special cableway of laying or track to run for conveying arrangement, the erection cost of cableway-type is higher, stability in operational process and the bad guarantee of safety, the erection cost of rail mounted is lower relative to the cost of cableway-type, the stability in operational process and the relatively good guarantee of safety.
The orbital fashion main following three kinds: one of existing rail mounted mountain region transportation device utilizes gear and the intermeshing mode of tooth bar.Weld tooth bar in orbit, and gear is installed on transportation device, by constantly engagement advance (this form is mainly in the majority with single track) thus realization is climbed between device self power driven wheel and track upper rack; Two is utilize mutually to compress between roller and track and the form of the friction force of generation drives advance (this form is also in the majority with single track); Three is utilize the mode being mutually wound around between steel rope and head roll and producing friction.Arrange the steel rope for drawing between track in advance, conveying arrangement is by head roll lay winding wire ropes thus (this form is in the majority to require to report his or her problems within a prescribed time and in a prescribed place) is advanced in realization climbing.
The first type of drive is the most reliable, and propulsive effort is comparatively large, but will manufacture very long tooth bar, and manufacturing cost is higher.The second type of drive is the simplest, but propulsive effort is obviously on the low side, and load and ramp angle are all less; The third type of drive is simpler relative to the first structure, because what adopt is Steel rope drive, so cost is lower, but braking and speed-regulating function are not very well, simultaneously because the continuous winding of cylinder and steel rope all can cause larger wearing and tearing to steel rope and cylinder.The first is because what adopt is the mode of rack and pinion engagement, therefore the precision of its speed governing and location is the highest, but because need to install the tooth bar grown the same as track in orbit, therefore price is higher, if the disposable processing of method sectional type of cold forging can be adopted, then connected the expense greatly can saved processing in orbit and install by the mode of welding.
Domestic and international existing rail mounted mountain region transportation device is all that the combustion engine of employing is as power mostly simultaneously; noise is larger; be unfavorable for the protection of mountain environment; and regulate at positioning precision and speed the deficiency that in accuracy, existence is very large; substantially can only meet the requirement of Material Transportation, and the integrated operation with other automated machine (such as automatic medicine spraying device etc.) can not be realized.Be that the rail mounted mountain region transportation device of driving and control is also because the huge cost of electric wire erection on a small quantity with electric power, what substantially use is all the electric power of battery storage, need in use procedure frequently to change battery, also need to bear the risk that unexpected power-off brings in the driving process of slope simultaneously.Therefore in order to solve the problem of hill slope transport difficult better, following several new requirement is proposed to new mountain region transportation device:
(1) laying of track wants simple, convenient, can not be too high to the requirement of landform, can lay, do not need to destroy original ground on a large scale in process of deployment according to mountain shape.
(2) power resources will become electrical motor from internal combustion engine development, reduce vibration & noise when running, and increase running stability, modern electric machines control technology application are come in simultaneously, improve the speed adjusting performance of transportation device and the precision of parking.
(3) electricity getting device wants structure simple, and erection is convenient, under the prerequisite avoiding large-scale track laying, avoids using battery as main power supply as far as possible.
