Abstract
The utility model relates to a hydraulic self-clamp device for detaching wheels, which is composed of a manual oil press machine, a regulating screw rod, a regulating slide block of claw open-close, a regulating draw rod of claw open-close, a wheel unloading draw rod, a top push rod, an adjustable top push rod and a claw, wherein, the regulating slide block of claw open-close has a threaded match with the regulating screw rod and is provided with a clutch mechanism. Both ends of the wheel unloading draw rod are respectively articulated with an articulated arm and the claw arm end part on the machine shell of the oil press machine. One end of the regulating draw rod of claw open-close is articulated with the articulated arm on the regulating slide block of claw open-close and the other end is articulated to the claw arm. The regulating screw rod is of a hollow type and one end of the regulating screw rod is hermetically connected with the oil of the oil press machine. The top push rod is arranged in a screw rod cavity, and one end of the top push rod is connected with a glide cylinder piston and the other end is extended out of the screw rod cavity. The adjustable top push rod has a threaded connection with the top push rod. The utility model has the advantage of labour saving of wheel unloading.
Description
The utility model relates to a kind of wheel puller.
At present the dismounting of wheel type parts generally all adopts wheel puller to carry out in the operation of the various machinery equipments of maintenance, makes machine breakdown to prevent to tear open in the wheel operation wheel shaft curved.The equal armrest of existing wheel puller propulsion arm moves screws propelling, because the service condition of machinery equipment, the difference of environment, the dead wheel type parts of particularly motionless for many years generation rust need apply huge jacking force when dismantling could be with it by unloading on the axle, at this moment often on the turn handle of propulsion arm, screw moment with increasing by the suit extension bar, thereby make disassembling section become very inconvenient and difficult, also brought totally unfavorable influence for simultaneously safety operation.
The purpose of this utility model provides a kind of fluid pressure type from clamping wheel puller, so that it is laborsaving to unload wheel operation, and also safe and reliable.
Fluid pressure type is from clamping wheel puller by manual hydraulic press, adjusting screw(rod), cooperate with screw flight have a clutch collude pawl opening and closing adjusting slider, collude pawl opening and closing adjusting yoke, unload the wheel pull bar, propulsion arm, adjustable propulsion arm, colluding pawl constitutes, unload hinged its other end of articulated jib on wheel pull bar one end and the manual hydraulic press casing with to collude pawl arm end hinged, what have clutch colludes pawl opening and closing adjusting slider by overcoat, be loaded on the nut that is shaped on teeth in the overcoat with its outer circumference surface of adjusting screw(rod) threaded engagement, be contained in the outer telescopic bayonet lock that has return spring that puts and constitute, collude pawl opening and closing adjusting yoke one end and collude hinged its other end of articulated jib on the pawl opening and closing adjusting slider and be hinged on and collude on the pawl arm.Adjusting screw(rod) is a hollow-core construction, and adjusting screw(rod) one end is connected with manual hydraulic press cylinder seal.Propulsion arm is loaded in the adjusting screw(rod) bar chamber, and propulsion arm one end is connected its other end with manual hydraulic press piston and stretches out outside the adjusting screw(rod) bar chamber.Adjustable propulsion arm and propulsion arm thread connection.
Adopt fluid pressure type when clamping wheel puller dismounting wheel type parts, bayonet lock to be extracted, make the block of bayonet lock releasing to nut, the turn nut makes and colludes the pawl opening and closing and wheel type parts are clamped catch on, discharge bayonet lock then, bayonet lock cooperates with nut teeth block can not relatively rotate and be shifted it nut locking with adjusting screw(rod).Screwing adjustable propulsion arm makes it hold out against the wheel shaft end, shake manual hydraulic press handle hydraulic press piston under the oil pressure effect, advance forward propulsion arm is moved ahead by adjustable propulsion arm to the wheel shaft pushing tow application of force by stretching out in the adjusting screw(rod) bar chamber, thereby by collude pawl with wheel type parts by backing off on the wheel shaft, unload and discharge oil pressure after wheel is finished, hand is adjustable, and the ejection push rod is withdrawn propulsion arm again, will collude pawl and can be finished by wheel type parts unloading operation.
Various to take turns type parts operating personnel firmly little, laborsaving from clamping wheel puller dismounting to utilize fluid pressure type, can be easily with the various type parts of taking turns by unloading on the wheel shaft, can improve the security of operating efficiency and operation greatly especially for the dead wheel type parts of dismounting rust.
Accompanying drawing is embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.
Fig. 1 clamps the wheel puller structure chart certainly for fluid pressure type.
Fig. 2 is for colluding pawl opening and closing adjusting slider assembly structure partial enlarged drawing.
Fig. 3 is the A-A profile of Fig. 2.
As shown in the figure, fluid pressure type from clamp wheel puller by manual hydraulic press (1), adjusting screw(rod) (9), with the adjusting screw(rod) threaded engagement have colluding pawl opening and closing adjusting slider (10), collude pawl opening and closing adjusting yoke (5), unload wheel pull bar (3), adjustable propulsion arm (7), propulsion arm (8), colluding pawl (6) and constitute of clutch, unload hinged its other end of articulated jib (2) on wheel pull bar one end and the manual hydraulic press casing with to collude pawl arm end hinged.Have clutch collude pawl opening and closing adjusting slider by outer circumference surface be shaped on teeth nut (14), be loaded on overcoat (13) on the nut, be loaded on the outer scalable bayonet lock (16) that has Return spring (15) that cooperates with nut teeth block that puts and constitute, collude pawl opening and closing adjusting yoke one end and collude hinged its other end of articulated jib (4) on the pawl opening and closing adjusting slider and be hinged on and collude on the pawl arm.Adjusting screw(rod) is connected with manual hydraulic press cylinder seal, and adjusting screw(rod) is a hollow type.Propulsion arm is loaded in the adjusting screw(rod) bar chamber, and propulsion arm one end is connected its other end with manual hydraulic press oil cylinder piston and stretches out outside the adjusting screw(rod) bar chamber.Adjustable propulsion arm is threaded with propulsion arm.Wheel puller colludes pawl and can be three-jaw and also can be four paws.(12) are manual hydraulic press filling pump piston coupling bar among the figure, and (11) are the external rocking bar of hydraulic press filling pump piston.
