Above-mentioned motor 3 can be gasoline engine, also can be known motors such as diesel engine.Described oiling reversal valve 17 has adopted the two-bit triplet reversal valve in the present embodiment, and feasible substitute mode is also can adopt the 3-position-3-way reversal valve certainly.
Operating principle of the present utility model is: the motor-driven oiler of above-mentioned sleeper bolt mainly by bolt unscrew, winding device and oiling station two parts constitute, in the time of the Panasonic nut, nut is carried out up and down and the spraying of side; Also can unscrew, screw nut and the bolt oiling is carried out simultaneously, after oiling station is with fluid supercharging, atomizing, oil is sprayed at the whole body of rod of bolt.Specifically: described pressurized cylinder 6 can adopt a single-acting formula oil cylinder, the one chamber communicates with two-bit triplet oiling reversal valve 17, return spring is equipped with in another chamber, be divided into two-way, one the tunnel communicates by an one way valve 18 with oiling fuel tank 4, and another Lu Jingyi one way valve 19 communicates with nozzle 22 on the oiling sleeve 12.The hydraulic oil of getting when hydraulic pump 24 one tunnel enters and unscrews, screw reversal valve 16, operation unscrews, after screwing reversal valve 16, can realize the rotating of motor 7, one the tunnel enters pressurized cylinder 6 through two-bit triplet oiling reversal valve 17 (right position), spring in the pressurized cylinder 6 is compressed, at this moment oiling reversal valve 17 is got to oil suction position (position, a left side), spring in the pressurized cylinder 6 discharges, hydraulic oil in the pressurized cylinder 6 flows back to hydraulic oil container 2, pressurized cylinder 6 pistons are to left movement under the effect of spring force, one way valve 19 to nozzle 22 blocks, at this moment the machine oil in the oiling fuel tank 4 will be by oil-absorbing pipeline 21, be inhaled in the pressurized cylinder 6 through one way valve 18, operate oiling reversal valve 17 then and get to out oil level (right position), the hydraulic oil that hydraulic pump 24 is got promotes pressurized cylinder 6 pistons and moves right, high-pressure oil enters oil spout pipeline 20, at this moment oil-absorbing pipeline 21 is blocked by one way valve 18, oil spout pipeline 20 is more a lot of greatly than nozzle 22 diameters, and machine oil must reach certain pressure and could open nozzle 22, thereby the fluid of ejection atomizes.Unscrew, screw reversal valve 16 when any position, operation oiling reversal valve 17 can both be realized the suction and the ejection of oiling fluid, therefore whenever can both realize the bolt oiling that opposes at elasticity bolt.
On the body 125 of oiling sleeve 12, be equipped with a ring shaped oil passage 126, from ring shaped oil passage 126, be equipped with the perpendicular oil duct 124 that two 180 degree divide, at perpendicular oil duct 124 2 nozzles 22 are housed bottom, perpendicular oil duct 124 communicates with two nozzles, 22 1 end oil ducts, draw an oil input channel from ring shaped oil passage 126, oiling sleeve 12 outsides are equipped with a snap joint 121 and are communicated with oil input channel, and oil spout pipeline 20 is connected in the snap joint 121.
During operation, as shown in Figure 1, the motor-driven oiler of above-mentioned sleeper bolt is placed on the rail 13 for the treatment of operation one side, two bilateral travelling wheels 141 on the running gear 14 can be advanced on rail, oiling sleeve 12 and bolt sleeve 11 can running gear 14 for fulcrum moves up and down, can turn to opposite side from rail one side simultaneously.Ato unit 3, pumping plant 5 is started working, and unscrews, screws reversal valve 16 by operation, realize bolt sleeve 11 just commentaries on classics, stop and reversing.Power output by the regulator solution pressing system realizes regulating and control, and after each nut was wrenched, operation relief lever 9 made the hydraulic system off-load, then handrail is upwards lifted, thereby can easily sleeve and nut be separated.
During the pine removing nut, oiling sleeve 12 is the contact fastener earlier, and oiling sleeve 12 will compress spring 123 (as Fig. 4) then, and bolt sleeve 11 is enclosed within on the upright bolt and nut, can prevent the rotation of oiling sleeve 12 by guide rod 122.When bolt sleeve unscrews nut, operation oiling reversal valve 17 is to position, a left side (as shown in Figure 5), pressurized cylinder 6 is from the 4 interior oil suctions of oiling fuel tank, after nut Panasonic, pull oiling reversal valve 17 again to right position, promptly, make the position of pressurized cylinder 6 oil spouts, oil-out 65, the oil spout pipeline 20 of fluid through increasing cylinder 6 enters oiling sleeve 12, opens nozzle 22, and the opposition nut carries out spraying operation.Every operation oiling reversal valve 17 1 times, then finish fluid suction and the ejection once, as a distributive value deficiency, can operate oiling reversal valve 17 once more.In the spraying that whenever can both realize bolt that is unscrewing, screwing upright nut, motor-driven oiling unscrews, screws interference mutually of nut with motor-driven.
The above, it only is specific embodiment of the utility model, when can not limiting the scope that the utility model is implemented with this, i.e. equivalent variations and the modification of doing according to the utility model claim and description generally all should still belong in the scope that the utility model patent contains.
