Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is done into a detailed description.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, the invention provides a kind of differential and drive liftable mechanism, comprise frame 11, be fixed on the driving assembly in frame 11, with the differential assembly driving assembly to be connected by chain, the wheel set be connected by chain with differential assembly and the spiral lift 10 be installed on wheel set, and the electric control system be connected with described spiral lift 10.Differential assembly comprises diff 9, hinge wheel 3 and differential minor sprocket 4, and hinge wheel 3 is installed on the input shaft of diff 9, and differential minor sprocket 4 is installed on the output shaft of diff 9.Driving assembly to comprise and drive reducing motor 1 and drive minor sprocket 2, drive minor sprocket 2 to be fixed on and drive on reducing motor 1, by driving the rotation of reducing motor to slow down, making driving minor sprocket export suitable rotating speed; Drive minor sprocket 2 to be connected with hinge wheel 3 by the first chain 8, drive minor sprocket 2 will rotate through the first chain 8 and pass to hinge wheel 3, then transmitted again by diff 9 and give 2 differential minor sprockets 4.In driving reducing motor 1 rotation process, by the transmission of the first chain 8 and the effect of diff 9,2 differential minor sprockets 4 are rotated simultaneously, and can differential function be realized in equipment turning process.Wheel set comprises wheel sprocket 5 and wheel 6, wheel sprocket 5 is fixed on the output shaft of wheel 6, wheel sprocket 5 is connected with differential minor sprocket 4 by the second chain 7, and differential minor sprocket 4 will rotate through the second chain 7 and pass to wheel sprocket 5, finally realize the rotation of wheel 6.Simultaneously due to the differential function of differential assembly, wheel 6 can be rotated by differential in turning process flexibly.Spiral lift 10 is installed on wheel 6.Wheel set has two covers, and often overlap on wheel set and be separately installed with spiral lift 10, the lifting of spiral lift is controlled by the electric control system of outside, adjustment wheel tracks is disembarked the height of frame, realize the level of frame or remain unchanged horizontal by certain angle, making frame not by the impact of floor level change.
Because this cover mechanism adopts chain and chain sprocket drive, in the process of wheel lifting, because chain allows certain sagging degree, make still can realize in wheel lifting process driving differential function.
Differential of the present invention drives liftable mechanism to be arranged on a kind of laser observing and controlling groove cleaning machine for clearing up Foundation trench, and carry out fieldwork in a building ground, site area is about 125m × 70m, adopts installation groove cleaning machine of the present invention to carry out Land leveling.JP3 laser transimitter is placed in the position of northeast corner, model machine starts thing, and essence is flat line by line from northwest corner, projector is while giving off laser beam, also rotate with the speed of 200 ~ 500r/min, define one with JP3 laser transimitter be the center of circle, radius 200m, the horizontal surface strafed by laser, as the benchmark reference plane of operation of leveling land.Start groove cleaning machine, drive reducing motor 1 to start working, and pass to wheel 6 by differential assembly, drive complete machine to advance.By the differential function of diff 9 in turning process, make two wheels export different rotating speeds, complete cornering operation.The work speed of walking is 1.50 ~ 2.50m/min, is arranged on the rough and uneven in surface degree of the laser pick-off chance on groove cleaning machine according to the benchmark reference plane perceiving ground of laser transimitter in walking process.Control signal is exported by comparing calculation by electrical control system, the motor controlling spiral lift 10 rotates, the screw rod of automatic control spiral lift 10 stretches and adjusts the height of two wheels respectively, makes the indexed plane cutting native cutter maintenance location, can complete high-precision prepartion of land operation.In operating range, install groove cleaning machine of the present invention and operate steadily, working properly, the smooth precision of final detection, error≤20mm, smooth precision is high.In conjunction with actual, illustrate that the present invention is very stable in walking application mechanically, differential can be realized and drive and elevating function, and structure simple, be convenient to installation, easy to maintenance.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
