The fully automatic hydraulic governor, be on the belt feeder middle frame, aligning carrier roller to be installed, on the middle frame of belt both sides, inspection is installed and drives wheel, oil pump by two fixed supports, composite oil cylinder (oil cylinder, oil circuit integrated package formation composite oil cylinder are installed in fuel tank) is set between aligning carrier roller and one of them fixed support, composite oil cylinder cylinder body and fixed support are hinged, the carrier roller frame rotating element of composite oil cylinder piston rod and aligning carrier roller is hinged, and the oil suction of oil pump is connected with oil pipe with the hydraulic fluid port of oil outlet with the composite oil cylinder afterbody.When utilizing belt deviation, belt edge is driven wheel with inspection and is contacted, drive inspection and drive the rotation of wheel drive oil pump, oil pump sucks hydraulic oil from the fuel tank of composite oil cylinder, pressure oil output enters an epitrochoidal chamber of oil cylinder by the oil circuit integrated package in the composite oil cylinder, and the hydraulic oil of another epitrochoidal chamber is got back in the fuel tank of composite oil cylinder by the oil circuit integrated package, realize the oil cylinder crank motion, drive aligning carrier roller front and back deflection and carry out belt correcting.
The hydraulic pressure device for adjusting deviation of above principle, though existing many products use in each big steel mill of the whole nation, power plant and mine, all are to have the complex structure multiple faults, its root problem is the complicated in mechanical structure of existing hydraulic pressure device for adjusting deviation, the hydraulic efficiency pressure system element is many, and it is big that probability appears in fault.Particularly the rotating speed of oil pump is lower than 400 rev/mins, out of reach Machinery Ministry oil pump standard revolving speed (must greater than 600 rev/mins), and the normal recommended pump speed is at 1000～1500 rev/mins, so the out-of-action situation of not oil suction of oil pump hydraulic pressure device for adjusting deviation occurs.
The utility model content
The purpose of this utility model is exactly at existing hydraulic pressure device for adjusting deviation above shortcomings, by improving design, change its principle of work and drive mechanism, provide a kind of simple in structure, low cost of manufacture, convenient for installation and maintenance, fault is few, entangle the limit and adjust stable performance, effective novel hydraulic aligning gear.
The purpose of this utility model is to realize like this, the novel hydraulic aligning gear, comprise that fixed support, tuningout oil cylinder, oil pipe, aligning carrier roller and inspection drive wheel, it is characterized in that being provided with the inclined to one side oil cylinder of left and right survey, tuningout oil cylinder, the inclined to one side oil cylinder of left and right survey and aligning carrier roller are installed on the fixed support, the piston rod of tuningout oil cylinder connects aligning carrier roller, left and right inspection is driven wheel and is articulated and connected with the cylinder body of the inclined to one side oil cylinder of left and right survey respectively, and the oil outlet pipe of the inclined to one side oil cylinder of left and right survey is connected with rod chamber with the rodless cavity of tuningout oil cylinder respectively.
The inclined to one side oil cylinder of described survey equates with the working chamber volume of tuningout oil cylinder.
Described aligning carrier roller comprises up belt training idler and descending belt training idler, and up belt training idler is installed by aligning carrier roller frame and flute profile carrying roller and connected and composed, and descending belt training idler is installed by aligning carrier roller frame and straight carrying roller and connected and composed.
Described fixed support is configured to by install connecting tuningout cylinder bracket and left and right on the aligning support.
Described left and right inspection is driven between wheel and the inclined to one side oil cylinder of left and right survey and is respectively equipped with connecting rod and is connected.
Being provided with the air pressure balance pipeline between the inclined to one side oil cylinder of described left and right survey interconnects.
When the belt transporter driving belt moves (belt direction of travel is the place ahead), when belt sideslip to the left, the cross travel that produces during sideslip, make left side inspection drive wheel and drive the left inclined to one side cylinder action of surveying, the pressure oil of the inclined to one side oil cylinder of left side survey enters the rodless cavity of tuningout oil cylinder by oil pipe, make piston rod stretch out, promote the aligning carrier roller clickwise.Running deviation value is big more left, and the length that the piston rod of tuningout oil cylinder stretches out is just long more, and then the angle of aligning carrier roller clickwise is just big more, forces the belt of sideslip to revert to the position at belt feeder center, realizes the function of belt centering operation.
In like manner, when belt sideslip to the right, the cross travel that produces during sideslip, make right edger roll inspection drive wheel and drive the right inclined to one side cylinder action of surveying, the right pressure oil of surveying inclined to one side oil cylinder enters the rod chamber of tuningout oil cylinder by oil pipe, makes the piston rod withdrawal, pulling aligning carrier roller left-hand revolution.Running deviation value is big more to the right, and the length of the piston rod of tuningout oil cylinder withdrawal is just long more, and then the angle of aligning carrier roller left-hand revolution is just big more, forces the belt of sideslip to revert to the position at belt feeder center, realizes the function of belt centering operation.
The utility model compact conformation is rationally simple, manufactures easily, and is easy for installation, and belt entangles the limit and adjusts effective.Adopt the inclined to one side oil cylinder of survey to equate, be connected, realize closing circulating oil path, make whole hydraulic circuit hermetically sealed, overcome harsh environment fully by high-pressure rubber pipe (left and right output oil pipe and air pressure balance pipeline) with the working chamber volume of tuningout oil cylinder.Great advantage is not have oil pump, valve group, pile-up valve group, fuel tank etc. in the system simultaneously, it has not only overcome former hydraulic pressure deviation correcting device because the oil suction instability of oil pump when low speed, faults such as the pile-up valve group is easily stuck, and significantly reduced productive costs (be about former cost 60%), avoided the service expenditure of on-site installation debugging and multiple faults.
The novel hydraulic aligning gear is an independently integral body; adopt the fixed support integral type to be installed on the middle frame of belt feeder; whole hydraulic efficiency pressure system and aligning carrier roller have all been installed when dispatching from the factory and connected; having added the hydraulic oil debugging finishes; need not at the scene to instruct and install; only need whole hydraulic pressure aligning gear once mounting on the middle frame of belt feeder, simple and convenient, reduce and shut down the set-up time.
