Abstract
A steering mechanism of a large road surface automatic feeding cutting machine comprises a machine frame provided with a nose lifting mechanism and a pair of rear driving wheels. The steering mechanism is characterized by further comprising a pair of universal wheels which are arranged on a rear machine frame of the rear driving wheels, and the universal wheels have a suspension state and a touchdown state which can be converted. When the universal wheels are in the touchdown state, the rear machine frame can be lifted so that the rear driving wheels can be in the suspension state. As for one embodiment, the universal wheels are fixed on the rear machine frame through a wheel frame. As for another embodiment, the universal wheels are arranged on the rear machine fame through a turning type wheel frame. The steering mechanism is simple in structure and low in cost, and the whole large road surface automatic feeding cutting machine steers conveniently and freely.
Description
Technical field
The utility model relates to a kind of road surface auto-feed cutting machine, especially a kind of steering hardware of large-scale road surface auto-feed cutting machine.
Background technology
The road surface auto-feed cutting machine of prior art is to adopt rear drive sprocket structure.Drive train is provided with the similar type of external import of diff, expensive.For considering Cost Problems, the drive train of home-made model is not generally established diff, the little type product that body is light, and while turning to tune, operator firmly mentions rear drive sprocket and moves body and can complete.For body weight, 500 kilograms of left and right or larger large type product, steering structure must be set and just can complete and turn to tune operation.In production, need to design a kind of steering hardware for large type product simple in structure.
Utility model content
Problem to be solved in the utility model is to provide a kind of steering hardware of large-scale road surface auto-feed cutting machine, and it is simple in structure, with low cost, easy to use.
The utility model adopts following technical scheme: comprise frame, described frame is provided with machine head lifting mechanism and a pair of rear drive sprocket, it is characterized in that: also comprise a pair of cardan wheel, described a pair of cardan wheel is located on the rear side frame of rear drive sprocket, described a pair of cardan wheel is provided with the unsettled and two kinds of mode of operations that can mutually change that land, described a pair of cardan wheel, when landing mode of operation, can make a pair of rear drive sprocket in vacant state rear side frame lifting.Its principle is: set up a pair of cardan wheel on rear side frame, when complete machine does not need steering operation, in vacant state.When needs turn to, a pair of cardan wheel is convertible into the state of landing, and meanwhile, rear side frame is lifted, and a pair of rear drive sprocket is unsettled, and a pair of cardan wheel has replaced rear drive sprocket and landed.Now, can complete easily the steering operation of complete machine.
A kind of improvement is that described a pair of cardan wheel is fixed on rear side frame by wheel carrier, by controlling machine head lifting mechanism, the mode of operation of convertible a pair of cardan wheel.This fixed type wheel carrier structure, when complete machine does not need steering operation, in vacant state.When needs turn to, by rotary handle, control machine head lifting mechanism and upwards lift head, be fixed on a pair of cardan wheel on rear side frame and around the wheel shaft of rear drive sprocket, be moved downward to the state of landing, now continue rotary handle, a pair of rear drive sprocket converts vacant state gradually to.Now, can conveniently complete complete machine steering operation.After having turned to, contrarotation handle, a pair of rear drive sprocket lands gradually, a pair of cardan wheel with vacant state, now complete machine can normal operation.
Another kind improves, and described a pair of cardan wheel is installed on rear side frame by a convertible wheel carrier, also comprises stop pin and crowbar, and when described convertible wheel carrier is upwards dug, a pair of cardan wheel is in vacant state, and stop pin can lock vacant state; While turning under described convertible wheel carrier, by crowbar, a pair of rear drive sprocket can be located to vacant state.Under convertible wheel carrier, turn over, a pair of cardan wheel lands, and presses down crowbar and can make rear drive sprocket unsettled, now, can conveniently complete complete machine steering operation.
The utility model is simple in structure, with low cost, complete machine steering operation convenient.
Accompanying drawing explanation
Fig. 1 is the first embodiment (showing fixed type wheel carrier) structural representation.
Fig. 2 is the second embodiment (showing convertible wheel carrier) structural representation.
The specific embodiment
As shown in Figure 1, the utility model the first embodiment comprises frame 1, described frame 1 is provided with machine head lifting mechanism 2 and a pair of rear drive sprocket 3, also comprise a pair of cardan wheel 4, described a pair of cardan wheel 4 is located on the rear side frame 5 of rear drive sprocket 3, described a pair of cardan wheel 4 is provided with the unsettled and two kinds of mode of operations that can mutually change that land, described a pair of cardan wheel 4 is when landing mode of operation, can make a pair of rear drive sprocket 3 in vacant state rear side frame 5 liftings, described a pair of cardan wheel 4 is fixed on rear side frame 5 by wheel carrier, by controlling machine head lifting mechanism 2, the mode of operation of convertible a pair of cardan wheel 4.Its principle is: that sets up is fixed on a pair of cardan wheel 4 on rear side frame 5, when complete machine does not need to turn to, in vacant state.When needs turn to, by rotary handle 6, control machine head lifting mechanism 2 and upwards lift head, simultaneously, the a pair of cardan wheel 4 being fixed on rear side frame 5 is moved downward to around the wheel shaft of rear drive sprocket 3 state of landing, now continue rotary handle 6, a pair of rear drive sprocket 3 converts vacant state gradually to, and a pair of cardan wheel 4 has replaced rear drive sprocket 3 and landed.Now, can conveniently complete complete machine steering operation.After having turned to, contrarotation handle 6, a pair of rear drive sprocket 3 lands gradually, a pair of cardan wheel 4 with vacant state, now complete machine can normal operation.
Figure 2 shows that the utility model the second embodiment, described a pair of cardan wheel 11 is installed on rear side frame 13 by a convertible wheel carrier 12, also comprise stop pin 14 and crowbar 15, when described convertible wheel carrier 12 is upwards dug, a pair of cardan wheel 11 is in vacant state, and stop pin 14 inserts pin-and-hole 18 and vacant state can be locked; When described convertible wheel carrier turns over for 12 times, by crowbar 15, a pair of rear drive sprocket 16 can be located to vacant state.Convertible wheel carrier turns over (Fig. 2 is down turning shape state, and convertible wheel carrier 12 can overturn around axle 17) for 12 times, and a pair of cardan wheel 11 lands, and presses down crowbar 15 and can make rear drive sprocket 16 unsettled, now, can conveniently complete complete machine steering operation.
The utility model is not limited to the concrete structure of above-described embodiment, within the equivalent transformation of other homogeneous structure all falls into protection domain of the present utility model.
