Abstract
The invention discloses a wheel-tracked combined type walking platform, comprising a track wheel, a track and a rack; the walking platform is further provided with walking wheels, a supporting bracket and a bidirectional hydraulic cylinder, wherein at least three walking wheels are provided and distributed at both ends of the rack; one end of the supporting bracket is connected with a wheel shaft of the walking wheel, and the other end of the supporting bracket is connected with the rack through a hinge; and the bidirectional hydraulic cylinder is arranged between the rack and the supporting bracket. Based on the platform with four wheels, the track is installed at an abdominal part of the platform to assist the platform barrier-crossing. Simultaneously, the height of each walking wheel is designed to be adjustable, and the height is adjusted by the hydraulic cylinder. A part of the track is on the ground or off the ground by adjusting the height of the walking wheel. When the platform is driven on the flat road, the height of the walking wheels can be reduced to cause the track to be partially off the ground, so that the quick walking of the walking platform is realized.
Description
Technical field
The present invention relates to the travelling platform that a kind of Transport Machinery is used, especially relate to a kind of wheel-track combined travelling platform.
Background technology
That present most of compound type travelling platform has is wheel-track combined, walking combined, the crawler leg composite of wheel.When wheel-track combined travelling platform goes, adopt the four-wheel mode of motion that lands on smooth road surface.This pattern has common running on wheels flat-bed motion characteristics; Can advance, fall back, turn; And have that friction drag is little, energy consumption is low, motion flexibly steadily, characteristics such as working space is little; Can realize that travelling platform is long apart from the motion requirement on flat road surface, guarantee that it enters the people place of working fast and efficiently.Conventional at present wheel-track combined travelling platform has following shortcoming: one of which, wheel are carried out directly compound form (two crawler belts are affixed on the road wheel inboard), cross over the ability of gully and soft terrain, the chassis of not improving travelling platform though strengthened it.In the time of under big obstacle appears at platform, effective obstacle detouring still; Its two, the travelling platform height can't be adjusted, and the driving system of road wheel and crawler belt is comparatively complicated.
Summary of the invention
The objective of the invention is deficiency, a kind of wheel-track combined travelling platform is provided, in the process of walking for solving the problems of the technologies described above; Can adjust voluntarily according to the difference of road conditions; When running into general obstacle, can pass through behind the podium level through adjustment, restart when below platform, running into big obstacle crawler belt carry out through; Convenient and energy-conservation, improve conveying efficiency greatly.
The present invention is the deficiency that solves the problems of the technologies described above, and the technical scheme that is adopted is: a kind of wheel-track combined travelling platform comprises Athey wheel, crawler belt and frame; This travelling platform also is provided with road wheel, bracing frame and two-way hydraulic cylinder; Road wheel is provided with three at least, and is distributed in the two ends of frame, and an end of bracing frame is connected with the wheel shaft of road wheel; The other end is connected with hinge with frame, between frame and bracing frame, is provided with two-way hydraulic cylinder.
Described two-way hydraulic cylinder, one of which end piston rod is connected with the frame hinge, and other end piston rod is connected with the bracing frame hinge.
Crawler belt on the described frame and Athey wheel are provided with one group at least.
The section form of described frame is trapezoidal, is setting wide at the top and narrow at the bottom, and Athey wheel and crawler belt are arranged on the end face on the narrow limit of frame.
The invention has the beneficial effects as follows:
This device is contained in the flat-bed belly with crawler belt on the platform base of four wheels, the assistance platform obstacle detouring.Height with road wheel is designed to adjustable height simultaneously, and adjustment highly can realize through hydraulic actuating cylinder.It is perhaps liftoff to let crawler belt partly land through the height of adjusting road wheel.When on flat road, going, the height that can reduce road wheel makes the crawler belt part liftoff, can realize the quick walking of this travelling platform like this.The height that when road conditions are bad, can improve road wheel partly lands crawler belt, and at this moment road wheel can liftoffly also can land.
This travelling platform can be used for machines working in paddy field, mainly leans on crawler belt to overtake when in the paddy field, walking.Mainly lean on road wheel to overtake on the road surface preferably in road conditions, can improve the conveying efficiency of Work machine like this.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Reference numeral: 1, road wheel, 2, two-way hydraulic cylinder, 3, Athey wheel, 4, crawler belt, 5, frame, 6, bracing frame.
The specific embodiment
As shown in the figure, a kind of wheel-track combined travelling platform mainly is made up of Athey wheel 3, crawler belt 4, frame 5, road wheel 1, bracing frame 6 and two-way hydraulic cylinder 2; The section form of described frame 5 can be any regular shape, and for example oblong etc. is preferentially adopted to trapezoidal; And being setting wide at the top and narrow at the bottom, Athey wheel 3 is arranged on the end face on frame 5 narrow limits with crawler belt 4, is the belly position that Athey wheel 3 and crawler belt 4 are arranged on frame 5; The both sides frame that is positioned at crawler belt 4 working direction is provided with road wheel; Described road wheel 1 is provided with three at least, and is distributed in the two ends of frame 5, and an end of bracing frame 6 is connected with the wheel shaft of road wheel 1; The other end is connected with frame 5 hinges, between frame 5 and bracing frame 6, is provided with two-way hydraulic cylinder 2.Described two-way hydraulic cylinder 2; One of which end piston rod is connected with the side hinge of frame 5; Other end piston rod is connected with bracing frame 6 hinges; Adopt the height of two-way hydraulic cylinder adjustment road wheel, the different road wheels of adjustment in real time that like this can road conditions land the conveying efficiency of raising Work machine with crawler belts.
