Detailed description of the invention
Below by accompanying drawing, novel technical scheme is used to be described in further detail to this.
As shown in Figure 1, Multifunctional replaceable triangular track skidder comprises gripping apparatus, capstan engine device, board mounting device and triangular track running gear.When carrying out car loading operation, gripping apparatus is delivered to timber place by cantilever arrangement 29, upper gripping apparatus 5 is opened, skidder is walked forward, is pushed into by log in gripping apparatus chamber, and upper gripping apparatus 5 cuts out under the effect of hydraulic actuating cylinder 10, timber is picked up, skidder moves to by transport trolley, and upper gripping apparatus 5 is opened again, and timber is fallen on transport trolley under gravity.When carrying out skidding operation, skidder is parked on skid road, lift-launch steel plate 13 turns round under the effect of hydraulic actuating cylinder 10 fits with ground, steel rope is pulled to timber place, timber is bound, use capstan engine 8 by timber strand collection on lift-launch steel plate 13, carry steel plate 13 under the effect of hydraulic actuating cylinder 10, one end of timber to be lifted, timber is pulled to appointed place by skidder, carry steel plate 13 again to fit with ground, capstan engine reverses, and skidder runs forward, and timber is under gravity from landing lift-launch steel plate.
As shown in Figure 6, triangular caterpillar deivce is a kind of " certainly taking road surface " formula running gear to triangle crawler belt running gear operation logic, and when drive wheel crawler belt does twining movement, ground can produce opposite effect power to crawler belt, thus drives vehicle to advance.Three sections can be divided into when triangular caterpillar deivce is advanced, 1 ~ 2 is ground section, 2 ~ 5 is that slack list section, 6 ~ 1 is for driving section (pilled-in selvedge), when skidder is advanced forward, skidder Driving Torque is Mk, this torque produces the propulsive effort Ft (wherein, r is the dynamic radius of drive wheel) of Mk/r on drive wheel 20.Ft acts in the driving section of 6 ~ 7, be delivered to 8 ~ 1 through tension wheel 17 and drive section, pass to 1 ~ 2 ground section through support wheel 19, contact the antagonistic force Fk of a formation level at ground section with soil, this power is the propulsive effort of skidder, and its direction is identical with skidder working direction.Because Ft can be wound around crawler belt because of the rotation of tension wheel 17 and the friction of crawler belt and tension wheel 17 and propulsive effort and consume a part of power in the process transmitted, therefore the power that hypothesis driven wheel consumes is very η z, then the real propulsive effort of triangular caterpillar deivce is: Fk=Ft (1-η z).
The above; for the present invention's preferably detailed description of the invention; protection scope of the present invention is not limited to listed detailed description of the invention; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
