Abstract
The utility model provides a pushing disassembling tool for a crank shaft of a beam-pumping unit. According to the pushing disassembling tool, the edge of a quadrate top plate (5) is fixedly connected with the edge of a groove bottom plate (7) through a locating tube (6), wherein the quadrate top plate (5) is in parallel to the groove bottom plate (7); a thrust screw (2) spirally passes through the middle part of the quadrate top plate (5) from outside to inside; and the groove bottom plate (7) is provided with an U-shaped groove (9) at a position corresponding to an axis part of the thrust screw (2). According the pushing disassembling tool for the crank shaft of the beam-pumping unit provided by the utility model, the crank shaft is disassembled in a spiral pushing way, therefore, the crank shaft can be prevented from being damaged or deformed, and the convenience, safety and high efficiency can be guaranteed during constructing at the site; and meanwhile, the pushing disassembling tool also can be used as a spring exerciser for disassembling a belt wheel of a pumping unit with a large diameter. The pushing disassembling tool is simple in structure, convenient to use, and high in adaptability.
Description
Technical field
The utility model relates to maintenance tool technology or device in the beam pumping unit operation, especially beam type oil pumping machine crank axle pushing tow extracting tool.
Background technology
In the prior art, beam pumping unit is used more extensive in oil field operation.Beam pumping unit also claims girder-like oil pump, beam type crank balanced pumping unit, refers to contain walking beam, and by the linkage commutation, the oil pumper of crank pouring weight balance is commonly called as the machine of kowtowing.Beam pumping unit from oil production method for bar class oil production equipment is arranged.When beam pumping unit was worked, the transmission of motor became moving up and down of horse head through gearbox, toggle, and horse head moves up and down through the plunger that polished rod, sucker rod drive the down-hole deep well pump, thereby constantly the crude oil in the well is extracted out pit shaft.The crank axle of using at beam pumping unit has important value aspect equipment work and the adjusting.
For guaranteeing that working conditions of oil extractor and oil well occurrence are complementary, often need to adjust the operating technology parameter of oil pumper, to improve the oil recovery efficiency of individual well.Beam pumping unit goes downwards to oil pumping machine crank first apart from cement base about 1.5 meters in adjusting the operating technology parametric procedure, and just can remove and install with cement base basic horizontal position.During original stroke of adjusting oil pumper, knock with sudden force the crown nut with hammer after the crown nut being loosened 2 screw threads at every turn, very easily produce spark, also easily cause crown nut and crank axle to damage or distortion.
Summary of the invention
Goal of the invention of the present utility model provides a kind of beam type oil pumping machine crank axle pushing tow extracting tool, and this installs as specific purpose tool, with crank axle for convenience detach.
The purpose of this utility model will realize by following technical measures: be connected and fixed by positioning pipe between parallel square top board and trough floor edge, ecto-entad spins and penetrates the thrust screw rod in the middle part of square top board, in trough floor to opening U-lag in thrust screw axis position, top board outer tail end in the thrust screw rod side of exposing connects hexagonal cap, and the lower end that the thrust screw rod side of being positioned at top board is connected with trough floor connects cone.
Advantage of the present utility model and effect: penetrate the thrust screw rod by spinning between square top board and trough floor, dismantle crank axle to revolve the top mode, avoid crank axle to damage or distortion, convenient, safe when guaranteeing site operation, efficient; Simultaneously, can also use as chest expander, be used for the larger belt wheel for oil pumping machine of dismounting diameter.Simple for structure, easy to use, strong adaptability.
Description of drawings
Fig. 1 is embodiment 1 structural representation in the utility model.
Reference numeral comprises: hexagonal cap 1, thrust screw rod 2, center nut 3, fastening nut 4, square top board 5, positioning pipe 6, trough floor 7, cone 8, U-lag 9.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Be connected and fixed by positioning pipe 6 between parallel square top board 5 and trough floor 7 edges, spinning at square top board 5 middle part ecto-entads penetrates thrust screw rod 2, should open U-lag 9 in thrust screw rod 2 axis positions 7 pairs of trough floor.
The outer tail ends of thrust screw rod 2 side's of exposing top boards 5 connect hexagonal cap 1, and the lower end that thrust screw rod 2 side's of being positioned at top boards 5 are connected with trough floor connects cone 8.
Side's top board 5 and trough floor 7 corresponding outer rims are square.
Positioning pipe 6 is 4, and screw rod simultaneously, is worn in the positioning pipe 6 in 4 bights of the side's of being evenly distributed on top board 5 and trough floor 7, and the part outside this screw rod side of exposing top board 5 and trough floor 7 edges is installed fastening nut 4.
U-lag 9 is to trough floor 7 one side openings.
In the utility model, install respectively 4 positioning pipes 6 additional 4 outsides of playing the fixation screw rod, top side's top board 5 is connected by 4 positioning pipes 6 with lower channel base plate 7, and be fixed respectively with 8 fastening nuts 4, consist of main body of the present utility model, at center nut 3 of the center of the square top board 5 of this main body welding, thrust screw rod 2 is screwed in wherein, the lower end head of thrust screw rod 2 is fixed with and is cone 8, and the upper end afterbody is connected with hexagonal cap 1.
Using method of the present utility model comprises:
The utility model is pushed on the crank, make the lower end forecone 8 of thrust screw rod 2 aim at the centre bore of crank axles, with the double offset ring spanner hexagonal cap 1 of rotary thrust screw rod 2 afterbodys in the direction of the clock, can pull down crank axle.
This utility advantage comprises: avoids knocking with sudden force the crown nut and causing crown nut and crank axle to damage or distortion with hammer, and convenient, safe when guaranteeing site operation, efficient; Simultaneously, can also use as chest expander, be used for the larger belt wheel for oil pumping machine of dismounting diameter.
