Abstract
The utility model relates to a multifunctional oil pressure wheel disassembling apparatus, which belongs to a special tool which is used for the mechanical maintenance, the vehicle maintenance, the weight pushing, etc. The multifunctional oil pressure wheel disassembling apparatus has the double functions of a common pressure oil lifting jack and a thread bar type wheel disassembling apparatus. The multifunctional oil pressure wheel disassembling apparatus is characterized in that the external side of the main cylinder is provided with an annular oil storage cylinder whose inner part is provided with a pressure oil spring whose upper end is fixed with the top portion of the oil storage cylinder; the lower end of the pressure oil spring is provided with a sealing ring, and the lower portion of a small piston is provided with a two-position four-way change valve which is respectively communicated with the bottoms of the oil storage cylinder and the main cylinder through pipelines. The utility model which has the features of small operating force and universal operation can be widely used for the operations, such as the disassembly of belt wheels, bearings, and liners, the pushing of the weight, etc.
Description
The utility model relates to a kind of multi-functional pressure oil wheel puller, belongs to the specific purpose tool that is used for flight-line maintenance, vehicle maintenance, weight pushing tow etc.
The instrument that is used to unload belt pulley at present has screw mandrel formula wheel puller, promotes forward by manually twisting screw mandrel during work, and operating physical force is big, generally work simultaneously with two people, and the also employing ordinary jack that has, but ordinary jack can only vertical direction work.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and little, the universal work of a kind of operating force is provided, has the multi-functional oil pressure wheel puller of ordinary jack and screw mandrel formula wheel puller dual-use function.
The purpose of this utility model is achieved in that it comprises master cylinder, main piston rod, valve piston, control stick, active top, hook, hook rack, base etc., at master cylinder arranged outside annular oil storage cylinder, dress is pressed oily spring in this oil storage cylinder, press oily spring upper end to fix with the oil storage cylinder top, sealing ring is equipped with in the lower end; Two-position four way change valve is equipped with in the valve piston bottom, this reversal valve by pipeline respectively with oil storage cylinder and master cylinder bottom UNICOM.
The utility model compared with prior art not only has common wheel puller and press the repertoire of oily jack, but also it is little to have operating force, and characteristics that can universal work can be widely used in work such as flight-line maintenance, vehicle maintenance, weight pushing tow.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of two-position four way change valve of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model by master cylinder (1), main piston rod (2), oil storage cylinder (3), press oily spring (4), control stick (5), valve piston (6), two-position four way change valve (7), commutation handle (8), oil pipe (9), sealing ring (10), hook rack (11), hook (12), active top (13), add bar (14) etc. and form.Master cylinder of the present utility model (1) arranged outside annular oil storage cylinder (3), dress is pressed oily spring (4) in this oil storage cylinder (3), press oily spring (4) upper end to fix with oil storage cylinder (3) top, sealing ring (10) is equipped with in the lower end, oil is stored under certain pressure, during work under the effect of pressing oily spring (4), oil storage cylinder (3) though in oil work in any direction, oil all can arrive valve piston (6) smoothly; Two-position four way change valve (7) is equipped with in valve piston (6) bottom, and this reversal valve (7) passes through oil pipe line (9) UNICOM bottom oil storage cylinder (3) and master cylinder (1) respectively; Active top (13) is installed on the main piston rod (2), as required, also can adorn on the active top and adds bar (14).Hook rack of the present utility model (11) is provided with groove, and hook (12) bottom is assemblied in this groove, according to unloading wheel (15) diameter, adjusts the position of hook (12).During the utility model work, the reversal valve lever handle (8) that promptly commutates transfers to the A position, oil from oil storage cylinder (3) through reversal valve (7) O hole to the M hole again to valve piston (6), after control stick (5) pressurization, oil from reversal valve (7) N hole to the P hole again to master cylinder (1) cavity of resorption, during main piston rod (2) return, the commutation handle (8) of reversal valve (7) is transferred to the B position, oil just flows to valve piston (6) again to the M hole through the P hole from master cylinder (1) cavity of resorption, the pressurization back from N hole to O hole again to oil storage cylinder (3).
Claims (3)
