Magic hand for spraying concrete vehicle frame levelling gear
The utility model relates to magic hand for spraying concrete vehicle frame, is specifically related to make the levelling gear of vehicle frame maintenance level.
At present, the ejection function unit of magic hand for spraying concrete all concentrates on its vehicle frame platform, due to can not relative motion between vehicle frame and crawler body, cause jet robot on ramp when operation, vehicle frame is heeling condition, so that ejection function unit is also heeling condition, thereby causes jet performance to be subject to the impact in ramp and often break down.
Summary of the invention
Technical problem to be solved in the utility model is, for above-mentioned the deficiencies in the prior art, and a kind of magic hand for spraying concrete vehicle frame levelling gear is provided, and make the relative motion of the relative crawler body energy of jet robot vehicle frame, make vehicle frame horizontal operating condition of energy maintenance on ramp.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of magic hand for spraying concrete vehicle frame levelling gear, this magic hand for spraying concrete has PLC controller, be characterized in, this levelling gear is located between the vehicle frame and crawler body of this jet robot, and comprises leveling hydraulic ram, and this leveling hydraulic ram is connected with described PLC controller, and the cylinder barrel of this oil cylinder and the sole of crawler body are hinged, the expansion link of this oil cylinder and the bottom-hinged of vehicle frame.
Compared with prior art, the beneficial effects of the utility model are: the setting up of this levelling gear, can make vehicle frame rotate to guarantee vehicle frame on ramp when operation in horizontality, the each mechanical element on vehicle frame is all in level attitude, make element stable working, can effectively reduce fault rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model is magic hand for spraying concrete vehicle frame levelling gear, it is located between the vehicle frame 1 and crawler body 2 of this jet robot, comprise leveling hydraulic ram, this leveling hydraulic ram is connected with the PLC controller (not shown) of this magic hand for spraying concrete, and the cylinder barrel 3 of this oil cylinder is hinged with the sole (not shown) of crawler body 2, the expansion link 4 of oil cylinder and the bottom-hinged of vehicle frame 1.
So, in the time that magic hand for spraying concrete is constructed on ramp, under the effect of PLC controller, vehicle frame is upwards steeved under leveling hydraulic ram promotes, until parallel with horizontal surface, thereby can, by the flexible angle of adjusting vehicle frame swing of leveling hydraulic ram, make vehicle frame remain horizontality, reach the object of vehicle frame leveling.
