The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
Fig. 1 is the structural drawing of man-operated mechanism;
Fig. 2 is the structural drawing of external regulating mechanism;
Fig. 3 is the structural drawing of mechanical self-latching mechanism;
Fig. 4 is the additional Electrohydraulic push rod that above three kinds of mechanisms are arranged.
Referring to Fig. 4, man-operated mechanism 1 is contained in the afterbody of motor 2, when electroless state is worked, opens handle and shakes handgrip, can realize that motor output shaft drives the fine setting and the case of emergency of hydraulic work system by the gear that combines as a whole with handle and the gear engagement speedup transmission on the motor rear axle.Fig. 1 is a kind of enforcement structure of man-operated mechanism.Bolt 17 connects a bearing axle 19 on motor back seat 16, and slip socket one has the internal gear 20 of open circles shell of column on the bearing axle 19, is one with screw attachment after the open circles shell of column socket of the cannulated sleeve position of folding handle 23 and internal gear 20.When not having the electricity operation, folding handle is taken out from the handle folder 18 of motor back seat, and half-twist, press down handle again, internal gear 20 can be overcome spring 21 elastic force, locking ball 22 is extruded from the locating slot of bearing axle, internal gear slide to for 20 times with the motor rear axle on outside during gear 29 engagement, spring 21 and steel ball 22 are with internal gear 20 another locating slot location in the bearing axle.When internal gear 20 glides, break away from the controlling rod 24 that is provided with on the support 28, because the effect of hinging supporting shaft 25 is lifted controlling rod 24, with the spring contact disengaging of power control switch 27, supply disconnecton.26 is the motor back cover.
Referring to Fig. 4, regulating block 3 sealed attachment of external controlling mechanism are at the housing opening place, individual outer regulate the bolt power transmissions and act on for speed control rod 10 in the housing and pressure regulation bar 7 respectively to be transferred element in bidirectional hydraulic lock 9 in the liquid-way system and the spill valve 6, can reach the purpose of external speed governing and pressure regulation by two.4,5 is one-way valve and oil pump, specifically implements structure such as Fig. 2, and external adjusting bolt 31 can make screw rod press down, and forces in speed control rod 10 and pressure regulation bar 7 respectively by force transmission shaft 34.The upper and lower slip of speed control rod is actually the size that changes spill port in the bidirectional hydraulic lock, and the upper and lower slip of pressure regulation bar then is the aperture of regulating relief valve.On speed control rod 10 and the pressure regulation bar 7 Returnning spring 11 and 8 being set, is when regulating bolt when back-outing, and helps force transmission shaft 34 to move on resetting, and the effect of force transmission shaft 34 is mainly in order to prevent that leakage of oil is convenient to sealing.33 is seal ring, and 32 is nut.
Referring to Fig. 4, the piston rod 14 that is arranged in the oil cylinder 13 of housing 12 is power transmission executive components of Electrohydraulic push rod, and in order to make its power transmission self-locking reliable, it is very feasible increasing by a mechanical self-latching mechanism 15, and concrete structure as shown in Figure 3.Piston rod 14 passes behind the hole that is slidingly matched of pulling claw seat 35 again diameter and diminishes and pass taper projection 38, and together pass supporting base 40 backs with the column part of taper projection and connect with nut 42 and packing ring 41, when piston rod 14 need be moved to the left, hydraulic cylinder piston forces in piston rod, piston rod 14 forces in taper projection 38, it is moved to the left, must act on pulling claw 39 inner conical surfaces that hinged point 43 connects on the supporting base 40, the spring force that makes pulling claw overcome extension spring 37 on the extension spring seat 36 outwards opens, pulling claw breaks away from pulling claw seat draw-in groove, then piston rod promotes the taper projection, and the taper projection promotes supporting base, the jaw 46 that supporting base promotes to connect with nut 45 on the jaw seat 44 is as executive component.
Above Fig. 1, Fig. 2, three kinds of additional mechanism providing additional operations of Fig. 3, can any one or two kinds or the function of three kinds of existing Electrohydraulic push rods of conduct and electric liquid gyrator product increase (the mechanical self-latching mechanism among the application only is applicable to Electrohydraulic push rod), product is had more uses flexible, reliable advantage.
