Abstract
The utility model is disclosed is the directed trip hammer of a kind of beam type oil pumping machine crank pin dismounting, the crank pins of quick release beam pumping unit.This orientation trip hammer, comprises and swims hammer, trip hammer is set in sliding tube, and one end is connected with extension pipe, and the other end is hammered gear cap into shape with trip and is connected, and the front end of extension pipe is also connecting jackscrew, utilizes the slip in sliding tube of trip hammer to impact crank pins it is deviate from from pin-and-hole.The utility model will be brandished sledgehammer and ram and to pound crank pins, become to utilize that trip hammer is mobile stably to be impacted, impact trip hammer gear cap and make crank pins become flexible, deviate from.Utilize this instrument dismounting crank-pin, than shortening 2-3 hour with the traditional approach dismounting used time, not only easy to operate, and avoided work high above the ground, significantly promoted the security of dismantlement work.The utility model manufactures compared with fluid pressure type crank pins stripping attachment that cost is low, reliable operation, easy to use and carry.
Description
Technical field
The utility model relates to the extracting tool of petroleum industry beam pumping unit crank pin, and particularly the directed trip of a kind of beam type oil pumping machine crank pin dismounting is hammered into shape, the crank pins of quick release beam pumping unit.
Background technology
Crank pins is the crucial tie point of oil pumper, crank pin fracture accounts for 10%～20% of oil pumper total failare, once there is the disconnected fault such as de-, can cause oil pumper to turn over machine, rod deformation, badly damaged wellhead equipment, cause the parts damages of oil pumper 1/3～2/3, even entail dangers to personal safety when serious, the main path of avoiding above-mentioned accident is exactly timely dismounting and change crank pins.
In dismantling crank pins operation, site operation personnel are pounded out with sledgehammer at present.Operating personnel is in order to use hammer handled easily, must stand in the high empty position that there is no barrier around, so this just requires staff to stand and brandishes hammer in the upper plane of oil pumping unit reduction gearbox, personal safety can not get ensureing, and the long-term rust of pin is extremely in pin-and-hole, and the disassembling section time is long, two or three hours at least, at most time half a day, not only waste manpower, time, also affected rate while driving a well.
Within these several years, developed successively recently fluid pressure type crank pins stripping attachment, this instrument can address the above problem preferably, but use and find through scene, this device still shows slightly heavy, complex operation, and cost of manufacture is higher, need to develop a kind of more light and simple instrument, used for dismantling crank pins.
Summary of the invention
The purpose of this utility model is to overcome above technical deficiency, provides the dismounting of a kind of beam type oil pumping machine crank pin directed trip hammer, makes it manufacture that cost is low and operation is more easy, solves the problem of field stripping crank pin for pumping unit difficulty.
Technical solution of the present utility model is: the directed trip hammer of a kind of beam type oil pumping machine crank pin dismounting, comprise trip hammer, trip hammer is set in sliding tube, one end is connected with extension pipe, the other end is connected with trip hammer gear cap, the front end of extension pipe is also connecting jackscrew, utilizes the slip in sliding tube of trip hammer to impact crank pins it is deviate from from pin-and-hole.
Compared with prior art the utlity model has following useful effect: the utility model will be brandished sledgehammer and ram and to pound crank pins, become and utilized that trip hammer is mobile stably to be impacted, impact trip hammer gear cap and make crank pins become flexible, deviate from.Utilize this instrument dismounting crank-pin, than shortening 2-3 hour with the traditional approach dismounting used time, not only easy to operate, and avoided work high above the ground, significantly promoted the security of dismantlement work.The utility model manufactures compared with fluid pressure type crank pins stripping attachment that cost is low, reliable operation, easy to use and carry, has good result of use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, and unrestricted protection domain of the present utility model.Referring to Fig. 1, the directed trip hammer of a kind of beam type oil pumping machine crank pin dismounting comprises trip hammer 7, and trip hammer 7 is set in sliding tube 5, and one end is connected with extension pipe 4, and the other end is connected with trip hammer gear cap 8, and the front end of extension pipe 4 is also connecting jackscrew 2.Jackscrew 2 is flechette-type structures, and arrow front end coordinates with the central blind hole of crank pins, and the body of rod upper sleeve through between arrow and extension pipe 4 insurance rope sling 3.On insurance rope sling 3 and trip hammer gear cap 8, be all fixed wtih safety rope 1, safety rope 1 two ends are connected with becket bridle.Insurance rope sling 3 is provided with becket bridle and penetrates hole, and this Kong Zhongke penetrates the becket bridle of a safety rope 1; The becket bridle of another root safety rope 1 is welded on trip hammer gear cap 8.The rear end of trip hammer gear cap 8 can pack in the crown type nut bore of crank pin for pumping unit.Trip hammer 7 ends near jackscrew 2 one end are provided with trip leadman handle 6.
Below in conjunction with embodiment, specific works process of the present utility model is described:
1, adjust crank pins position;
2, in oil pumper rotation process, when crank pins is positioned at pumping unit gear shifting box front end, shut down brake, this instrument is installed:
3, the crank pins crown type nut that will change is dismantled and screws out half, trip hammer gear cap 8 in this instrument is inserted in crown type nut bore, and then by the central blind hole of jackscrew 2 another crank pins of aligning oil pumper, rotate and regulate jackscrew 2 to make sliding tube 5 fixing, and safety rope 1 being tied up on the left connecting rod and right connecting rod of oil pumper.Staff holds trip leadman handle 6 the push-and-pull trip hammer 7 of this instrument, makes trip hammer 7 impact trip hammer gear cap 8, makes crank pins loosening.
