Abstract
The utility model discloses a puller for detachment and assembly of a plunger pump. The puller comprises a supporting base and a push-pull mechanism arranged on the supporting base, wherein the push-pull mechanism is provided with a power output end capable of moving up and down along the vertical center line of the supporting base. The supporting base further comprises supporting upright columns circumferentially distributed along the vertical center line of the supporting base. Tail ends of the supporting upright columns are provided with fixing structures used for detachably and fixedly being connected with a flange face of a pump shell body. The power output end of the push-pull mechanism is provided with a connecting stud, and the lower end portion of the connecting stud is used for being connected with an inner thread hole of a pump shaft in a threaded mode. When the push-pull mechanism is a linear motion mechanism, the upper end portion of the connecting stud is fixedly connected with the power output end or is matched with the power output end in a relatively rotating mode. When the push-pull mechanism is a screw rod, the upper end portion of the connecting stud is matched with the power output end in a relatively rotating mode. By means of upward moving of the power output end, a combination of the pump shaft and the pump bearing is pulled out from the inside of the pump shell body. On the contrary, by means of downward moving of the power output end, the combination can be installed in the pump shell body in a pressing mode.
Description
Technical field
The utility model relates to a kind of plunger displacement pump dismantling device, is specifically related to a kind of horse of drawing.
Background technology
Drawing horse is a kind of of small tool, claims thruster again, is widely used in dismantling various axles and tightens machine components, as bearing, belt wheel, gear etc., by its pushing tow mode, be divided into screw usually to draw horse and hydraulic cylinder type to draw horse, by its hook quantity, be divided into two pawl Shi Lama and three-pawl type again and draw horse.Present screw draws horse, mainly comprises supporting seat, screw rod and hook, and screw flight is assemblied in the center of supporting seat, and each hook is articulated in the periphery of supporting seat.During use, hook catches on the edge of waiting to tear open part, and rotary screw makes its lower end withstand the upper end of axle, continues rotary screw afterwards, and hook drives to wait to tear open on the part and moves, thereby finishes dismounting.And hydraulic cylinder type draws horse and screw to draw the difference of horse to be, has changed screw rod into hydraulic cylinder, makes dismounting more convenient, more laborsaving; No matter be screw or hydraulic cylinder type, can only realize downward pushing tow axle, can not upwards draw, and limited by this version of hook, can only will wait that tearing part open dismantles from axle.But for L2F series plunger displacement pump, when dismounting, the assembly of bearing and axle need be extracted in housing together, if use the horse of drawing of existing this version, then can't be realized dismounting, bearing can only be pressed in the housing together with axle.
The utility model content
The purpose of this utility model provides a kind of pushing tow downwards, can upwards lift the plunger displacement pump dismounting that pump shaft extracts together or install in the pump case together with the assembly of realizing pump shaft and pump bearing again draws horse.
The utility model adopts following technical scheme: horse is drawn in a kind of plunger displacement pump dismounting, comprise supporting seat and be arranged on push-pull mechanism on the supporting seat, push-pull mechanism has the clutch end that moves up and down along the vertical center line of supporting seat, also be provided with on the described supporting seat along the support post of its vertical center line circumferential arrangement, the end of each support post has the fixed structure that is removably fixed with for the flange face with pump case, and the clutch end of described push-pull mechanism is provided with the bottom and is used for being connected double-screw bolt with the internal thread hole of pump shaft is threaded; When push-pull mechanism was straight-line motion mechanism, the upper end of described connection double-screw bolt was connected or relatively rotates with described clutch end and cooperates; When push-pull mechanism was screw rod, the upper end of described connection double-screw bolt relatively rotated with described clutch end and cooperates.
Described supporting seat is cross structure, described each support post is arranged at respectively on four sections of cutting apart of supporting seat, described fixed structure be separately fixed at each support post end, turning edge of turning up, respectively turn edge have for the pump case flange face on four flange holes respectively corresponding, for the threaded connection hole of screw connection.
Described each support post is respectively by being arranged on the supporting seat along the corresponding mobile slide block of segment length direction guiding of cutting apart separately, on each slide block respectively screw thread be equipped with the separately corresponding section of cutting apart roof pressure and cooperate the dog screw of realizing that each slide block is located.
Described push-pull mechanism is that screw thread is assemblied in the screw rod in the supporting seat, described clutch end is the lower end of screw rod, the upper end of described connection double-screw bolt relatively rotates with described clutch end by the adapter sleeve that is fixedly set in the screw rod bottom and cooperates, the nut of described connection double-screw bolt upper end stretches in the adapter sleeve, turn in the lower end of adapter sleeve has, with the annular retaining edge that the nut block that is connected double-screw bolt cooperates, the annular retaining is along having the endoporus adaptive with the bar portion that is connected double-screw bolt.
Go back screw thread on the described connection double-screw bolt and be equipped with the locking nut that cooperates for pump shaft end face roof pressure.
Adopt the plunger displacement pump dismounting of said structure to draw horse, because the lower end of each support post has the fixed structure that the flange face with pump case is removably fixed with, can realize the fixing of supporting seat and support post and pump case by fixed structure, the clutch end of push-pull mechanism is connected by connecting double-screw bolt and pump shaft simultaneously, move just and the assembly of pump shaft and pump bearing can be extracted in pump case together on the dependence clutch end, opposite, rely on moving down just of clutch end assembly can be press fit in the pump case.
Further, supporting seat is cross structure, each support post can be regulated the folding distance of each support post like this by cutting apart the slide block that the guiding on the segment length direction moves and be assemblied on the supporting seat along corresponding separately, with the dismounting of the plunger displacement pump that adapts to the different model size.
