Abstract
The utility model relates to a pavement milling machine front discharge door ground clearance self-adapting device, which comprises a conveyer support, a hydraulic cylinder, an electromagnetic valve and a controller. The conveyer support is connected with a front discharge door of a milling machine; the hydraulic cylinder is capable of driving the front discharge door and the conveyer support to ascend and descend; the electromagnetic valve is capable of controlling ascending and descending movement of the hydraulic cylinder; a position sensor installed at the bottom portion of the conveyer support is capable of detecting swing angles of a swing device; the controller is capable of outputting ascending and descending control instructions to the electromagnetic valve; the position sensor is capable of outputting ascending or descending control signals to control signal input portion of the controller; the control signal input portion of the controller is also connected with a manual selection switch capable of inputting the ascending or descending control signals; and the controller is connected with the position sensor through a state switching switch. The pavement milling machine front discharge door ground clearance self-adapting device is capable of automatically adjusting heights of the pavement milling machine front discharge door and a conveyer, simultaneously having high detecting accuracy, high use reliability and long service life.
Description
Technical field
The utility model belongs to field of road engineering machinery, and the structure of output pavement milling machine specifically is a kind of ground clearance of front discharge door of pavement milling machine self-reacting device before relating to.
Background technology
The preceding output pavement milling machine of taking back material collecting device is when carrying out milling work, and the waste material that milling is got off comes out by the discharging opening impelling of milling and planing drum the past earlier, falls on the defeated material belt, is transported in the truck by defeated material belt and transports.Because milling machine output bin gate and conveyer are at the front end of milling and planing drum, under the situation of the corrupted road surface of complexity, the terrain clearance of output bin gate and conveyer is control in real time, bin gate and conveying function are with road surface situation lifting when meeting the road surface sudden change with assurance, avoid itself and pavement friction to cause conveyer belt to damage or the bin gate resistance excessive, simultaneously terrain clearance again can not be excessive, otherwise waste material impelling quantity not sufficient can occur or overflow from the bottom.Existing milling machine control system still can't realize this requirement preferably.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of milling machine that can detect in real time to treat work pavement behavior and adjust bin gate and conveyer height automatically, simultaneously accuracy of detection height, dependability height, long preceding discharge door of pavement milling machine and conveyer terrain clearance self-reacting device of life-span according to testing result.
Ground clearance of front discharge door of pavement milling machine automaton of the present utility model includes conveyer bridge, the hydraulic cylinder that can drive preceding discharge door and conveyer bridge lifting that is connected with the preceding discharge door of milling machine, the electromagnetic valve that can control hydraulic cylinder ground lifting action, it is characterized in that: the position sensor that is used for detecting the road surface is installed in the conveyer bridge bottom, this position sensor can detect the pendulum angle of a pendulous device, this pendulous device one end is hinged on the conveyer bridge, and the other end contacts with ground; Also including one in the utility model device can be to the controller of above-mentioned electromagnetic valve output rising and decline control instruction; Described position sensor can rise or the decline control signal to the output of the control signal importation of controller; The control signal importation of controller also is connected with the manual selection switch that can import rising or decline control signal; Controller also is connected with position sensor through a state switch, is used for control position working sensor or quit work.
The utility model can just change according to the road surface when work, by position sensor the ground level information conveyance is arrived controller, give electromagnetic valve through output order after the logical process, discharge door and conveyer terrain clearance can monitor and adjust in real time before making, effectively having avoided conveyer belt to contact with earth bulging with ground friction damage or preceding bin gate increases resistance, has prolonged its application life of parts; Its control accuracy height of while, good operating stability.
Description of drawings
Fig. 1 is the frame for movement schematic diagram of the utility model embodiment;
Fig. 2 is the control principle figure of the utility model embodiment.
The specific embodiment
As shown in the figure, this device includes conveyer bridge 2, the hydraulic cylinder 3 that can drive preceding discharge door and conveyer bridge lifting that is connected with the preceding discharge door 1 of milling machine, the electromagnetic valve YV1 that can control hydraulic cylinder ground lifting action, in the conveyer bridge bottom position sensor SQ1 that is used for detecting the road surface is installed; Position sensor SQ1 can detect the pendulum angle of a pendulous device 5, and these pendulous device 5 one ends are hinged on the conveyer bridge, and the other end contacts with ground; Also including one in the device can be to the controller 4 of electromagnetic valve YV1 output rising and decline control instruction; Position sensor SQ1 can rise or the decline control signal to the output of the control signal importation of controller; The control signal importation of controller also is connected with a manual selection switch SA2 that can import rising or decline control signal; Controller also is connected with position sensor SQ1 through a state switch SA1, is used for control position working sensor or quit work.State switch SA1 is used for switching manual work state, automatic mode or halted state, and only can effectively exporting when automatic mode of position sensor SQ1 risen or the decline control signal; No matter automatically still during the manual work state, manual selection switch SA2 all can effectively export and rise or the decline control signal, has guaranteed the emergency processing of special circumstances.
