Abstract
The utility model discloses a hydraulic puller, which solves the problems that the prior operation for detaching a belt pulley is easy to cause the deformation of a wheel rim and the like; the hydraulic lifting device comprises a hydraulic jack, a hydraulic jack rod, a threaded pipe, a handle nut and two closed handles, wherein the handle nut is in threaded connection with the threaded pipe; the closed handle main part is square frame shape, and the rear end of two closed handles articulates respectively on the handle nut, and the two is parallel to each other, and the front end of closed handle has half moon shape structure, and two half moon shape structures of two closed handles constitute circular structure class jointly, and this type of circular structure perpendicular to hydraulic jack center pin. The belt pulley is disassembled by the puller, so that the force bearing area of the belt pulley is increased, and the deformation and damage of the belt pulley caused by improper disassembly are effectively avoided.
Description
Technical field
The utility model relates to a kind of extracting tool, particularly dismantles the specific purpose tool of belt pulley, bearing or shaft coupling etc. from axle.
Background technology
Rod-pumped well adjusts the diameter of jig frequency, maintenance motor and 660V high-voltage motor belt pulley less, during dismounting motor pulley, usual use tri-paw puller, pulling force acts in belt pulley outer rim 3, owing to belt pulley being arranged some belt grooves, thus the tensile strength of belt pulley outer rim is reduced, so chest expander is pulled through in journey on top, can cause the deformation of belt pulley, pulling claw is easily slippage also, and disassembling section is time-consuming, effort, efficiency are low.
Summary of the invention
The utility model relates to a kind of hydraulic jacking drawer, and this hydraulic jacking drawer can increase the lifting surface area of belt pulley to greatest extent, and the setting of point of force application also avoids the lower outer rim of the tensile strength of belt pulley, avoids belt pulley by the generation of drawing deformation phenomenon.
In order to realize foregoing invention object, the technical solution adopted in the utility model is: a kind of hydraulic jacking drawer, comprise hydraulic jack, hydraulic jack bar, screwed pipe, handle nut and two closed handles, described handle nut is tetragonal body, handle nut arranges horizontal threaded bore, and screwed pipe is connected with handle nut thread; The internal diameter of screwed pipe is corresponding to the external diameter of hydraulic jack bar, and hydraulic jack bar is inserted in screwed pipe, and the tail end of hydraulic jack bar withstands on the push rod end face of hydraulic jack; Described closed handle main body is square frame-shaped, the rear end of two closed handles is hinged on handle nut respectively, the two is parallel to each other, the front end of closed handle has semilune structure, two semilune structures of two closed handles form similar round structure jointly, and such circular ring structure is perpendicular to hydraulic jack bar central shaft.
The beneficial effects of the utility model: use thruster dismounting motor pulley, belt pulley load area can be made to increase, and pulling force directly acts on motor shaft and belt pulley mating surface place, efficiently avoid because dismantling the improper belt pulley distortion caused and the generation damaging phenomenon, in addition, the dismounting for similar articles also can use, and only needs a people during operation, greatly reduce manpower and reduce labor intensity, disassembling section is easy, safe, efficient.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model hydraulic jacking drawer.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is closed handle semilune structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Shown in Fig. 1 composition graphs 2: a kind of hydraulic jacking drawer, comprise hydraulic jack 1, hydraulic jack bar 2, screwed pipe 3, handle nut 4 and two closed handles 5, described handle nut 4 is tetragonal body, and handle nut 4 arranges horizontal threaded bore, and screwed pipe 3 is threaded with handle nut 4; The internal diameter of screwed pipe 4 is corresponding to the external diameter of hydraulic jack bar 2, and hydraulic jack bar 2 is inserted in screwed pipe 3, and the tail end of hydraulic jack bar 2 withstands on the push rod end face of hydraulic jack 1; Described closed handle 5 main body is square frame-shaped, the rear end of two closed handles 5 is hinged on handle nut 4 respectively, the two is parallel to each other, as shown in Figure 3: the front end of closed handle 5 has semilune structure 6, two semilune structures 6 of two closed handles 5 form class circular ring structure jointly, and such circular configuration is mutually vertical with the central shaft of hydraulic jack bar 2.
During use, opening and closing is shaken hands, and adjustment closed handle front end semilune structure, makes it to lean against on the end face of belt pulley to be removed, the class circular ring structure that two semilune structures are formed, obviously increase with the contact area of belt pulley, the front end then adjusting hydraulic jack bar withstands on the axle center of motor shaft, and now hydraulic jacking drawer is fixing over pulleys carried, manually or electric hydaulic spanner, hydraulic top masterpiece is used on motor shaft, and reaction force impels closed handle to pull belt pulley, and dismantling belt pulleys gets off the most at last.
Claims (1)
1. a hydraulic jacking drawer, comprise hydraulic jack, hydraulic jack bar, screwed pipe, handle nut and two closed handles, described handle nut is tetragonal body, and handle nut arranges horizontal threaded bore, and screwed pipe is connected with handle nut thread; The internal diameter of screwed pipe is corresponding to the external diameter of hydraulic jack bar, and hydraulic jack bar is inserted in screwed pipe, and the tail end of hydraulic jack bar withstands on the push rod end face of hydraulic jack; It is characterized in that: described closed handle main body is square frame-shaped, the rear end of two closed handles is hinged on handle nut respectively, the two is parallel to each other, the front end of closed handle has semilune structure, two semilune structures of two closed handles form class circular ring structure jointly, and such circular ring structure is perpendicular to hydraulic jack bar central shaft.
