Embodiment Construction
[0028] Such as figure 1 As shown, the present invention includes two position sensors for real-time detection of the stroke positions of the two left and right leveling oil cylinders installed on the left and right big arms of the paver respectively, and the signals detected by the two position sensors are compared and analyzed. Correspondingly, a programmable controller 1 that controls and adjusts the on-off and opening of each solenoid valve in the left and right solenoid valve groups. The two position sensors are connected to the programmable controller 1, and the programmable controller 1 is respectively connected to the solenoid valves in the left and right solenoid valve groups. The left and right solenoid valve groups are respectively installed in the left and right hydraulic pipelines connected between the left and right leveling cylinders and the hydraulic pump 7, and the solenoid valve groups include a high-speed switching valve, an electromagnetic reversing valve an...

The invention discloses a protector for preventing a paver ironing plate from being twisted. The protector comprises two location sensors which are installed at the travel positions of left and right leveling cylinders on left and right side arms of the paver and carries out real time detection, and a programmable controller which carries out contrastive analysis on the detected signal and correspondingly carries out control adjustment on the connection / disconnection and opening degree of each solenoid valve in the left solenoid valve group and the right solenoid valve group respectively; both the two location sensors are connected with the programmable controller, and the programmable controller is respectively connected with each solenoid valve in the left solenoid valve group and the right solenoid valve group; the left solenoid valve group and the right solenoid valve group are respectively installed in hydraulic pipelines of left and right leveling cylinders and hydraulic pumps; and the left and right leveling cylinders respectively carry out control driving on the left and right arms. The invention is reasonable in design, simple and convenient in use operation, and reliablein movement, and can effectively solve the practical problem of forced twisting ironing out existing in the paving process of a prior paver.
Description
technical field [0001] The invention belongs to the technical field of road paving construction machinery application, and in particular relates to a protection device for preventing the screed of a paver from twisting and deforming. Background technique [0002] At present, the paver has become an indispensable road paving construction machine in the construction of high-grade highways, and has been widely used. However, with the continuous development of electronic technology and automation control technology, as well as the continuous improvement of high-grade highway construction requirements, the paver should be given the task of high intelligence and high automation functions. Paver, like other large-scale engineering machinery, has a rather complicated mechanical structure, so how to realize the coordination between the various mechanical components of the paver has always been a problem that needs to be solved in the design of the automatic control system of the pave...
