Abstract

The utility model relates to a novel well-drilling diesel-engine cylinder-sleeve dismounting tool that is applied to the petroleum well-drilling industry, which comprises a lead screw (1), a rotation nut (2), a bearing cover plate (3), a supporting disc (4) and the like, wherein, a soleplate (7) is connected with the lead screw (1) through a cylindrical pin (6) to form a lead-screw assembly; the rotation nut (2) and a bearing (5) are mounted on the supporting disc (4), which is covered by the cover plate (3) to form a supporting-disc assembly; the lead-screw assembly is vertically connected with the supporting-disc assembly through a trapezoidal thread, and the supporting-disc assembly is fixed by a diesel-engine cylinder-cover long bolt without a bracket. The tool has simple structure and convenient operation, and not only can simply pull out the cylinder sleeve, but also can press the cylinder sleeve into a steel-sleeve hole through homogenous stress, thereby preventing the cylinder sleeve from easily being damaged and deformed under the striking. In addition, the tool is convenient to carry, and is simple and convenient to be installed, and can randomly replacing the cylinder sleeve on the spot of the well-drilling team, thereby greatly improving the working efficiency and reducing the labor intensity.

Description

Novel drilling diesel engine cylinder sleeve dismantling device
Technical field
The utility model is to be used for the used a kind of engine maintenance instrument of oil drilling industry, is a kind of diesel cylinder sleeve dismounting and press mounting tool.Specifically, be a kind of novel drilling diesel engine cylinder sleeve dismantling device.
Background technology
Diesel engine is widely used in the oil and gas well drilling scene, often runs into the replacing cylinder sleeve in diesel engine is repaired, and the cylinder sleeve assembling has cooperation, is difficult to dismounting and press-fits when changing.The cylinder sleeve that has is cooled off incrustation scale and corrosion influences, and the dismounting difficulty is bigger.In the known technology, the patent No. is that the positive and negative screw thread internal and external threads cover that " the cylinder sleeve provision for disengagement " of 98221572.X adopted is realized the screw mandrel transmission, can only dismantle small-sized cylinder sleeve; The patent No. be 200621061771.X's " provision for disengagement of drilling diesel engine cylinder sleeve " though can dismantle big-and-middle-sized cylinder sleeve, structure is comparatively complicated, troublesome poeration, and can only dismantle and can not press-fit cylinder sleeve.
Summary of the invention
The purpose of this utility model provides a kind of novel drilling diesel engine cylinder sleeve dismantling device, and its structure is simpler, and operation is carried more convenient, is a kind of drilling diesel engine cylinder sleeve dismounting and press mounting tool.
The utility model is achieved in that and comprises screw mandrel, rotation nut, bearing cover, supporting disk, bearing, straight pin, base plate, base plate is connected to form the screw mandrel assembly by straight pin and screw mandrel, rotation nut and bearing are assemblied on the supporting disk, cover cover plate and form the supporting disk assembly, the screw mandrel assembly is vertically connected on the supporting disk assembly by trapezoidal thread.
Screw mandrel adopts trapezoidal thread.
The interior box thread of rotation nut is corresponding with the trapezoidal male thread of screw mandrel.
The cylindrical of rotation nut cooperates with bearing 5 endoporus.
The upper and lower faces of base plate is processed into stepped ramp type.
Bearing adopts circular cone roller bearing.
Advantage of the present utility model is: this instrument is by diesel engine cylinder cover stay bolt fixed support disc assembly, do not need support, simple in structure, easy to operate, not only easily drawing goes out cylinder sleeve but also the force-applied body steel bushing hole that uniformly cylinder sleeve is pressed into, and prevents that cylinder sleeve from knocking damaged easily down, distortion.Easy to carry in addition, simple installation can be increased work efficiency greatly arbitrarily at the on-the-spot cylinder sleeve of changing of drilling crew, reduces labour intensity.
Description of drawings
Accompanying drawing 1 is an overall structure schematic diagram of the present utility model.
Accompanying drawing 2 is local enlarged diagrams of Fig. 1.
Accompanying drawing 3 is base plate 7 front views of the present utility model.
Accompanying drawing 4 is base plate 7 vertical views of the present utility model.
The specific embodiment
As shown in Figure 1, form by screw mandrel 1, rotation nut 2, bearing cover 3, supporting disk 4, bearing 5, straight pin 6, base plate 7, base plate 7 is connected to form the screw mandrel assembly by straight pin 6 and screw mandrel 1, and base plate 7 can be convenient to put into counter the hanging on the cylinder sleeve edge in cylinder sleeve bottom around the straight pin rotation; To rotate nut 2 and bearing 5 is assemblied on the supporting disk 4, and cover cover plate 3 and form the supporting disk assemblies, the screw mandrel assembly is vertically connected on the supporting disk assembly by trapezoidal thread.The base plate 7 of screw mandrel 1 is rotated into certain Angle, put into that cylinder sleeve is counter to be hung or be pressed on the cylinder sleeve edge, assembly with supporting disk 4 is fixed on six fixed length double-screw bolts of diesel engine cylinder cover as required, (can increase the arm of force in case of necessity with spanner, adopt pipe wrench) rotate rotation nut 2 screw mandrel assembly vertical support dish 4 is moved up and down, realize anti-or hang and push extracting or being pressed into of cylinder sleeve by base plate.This tool construction is simple, easy to operate, and not only easily drawing goes out cylinder sleeve but also the force-applied body steel bushing hole that uniformly cylinder sleeve is pressed into, and prevents that cylinder sleeve from knocking damaged easily down, distortion.This instrument is easy to carry in addition, and simple installation can be increased work efficiency greatly arbitrarily at the on-the-spot cylinder sleeve of changing of drilling crew, reduces labour intensity.
As shown in Figure 1, screw mandrel 1 should adopt trapezoidal thread, is convenient to screw mandrel 1 transmission, gains in strength.Box thread is corresponding with the trapezoidal male thread of screw mandrel 1 in the rotation nut 2, and rotation nut 2 its cylindricals cooperate with the endoporus of bearing 5, rotate with bearing 5 inner orbits when work.Bearing 5 selects for use circular cone roller bearing can bear the big axially load of religion.
As shown in Figure 2, will rotate nut 2 and bearing 5 is assemblied on the supporting disk 4, and cover cover plate 3 and form the supporting disk assemblies, the screw mandrel assembly is vertically connected on the supporting disk assembly by trapezoidal thread.
Shown in accompanying drawing 3, accompanying drawing 4, base plate 7 upper and lower faces are processed into stepped ramp type, are embedded in to be convenient to drawing on the cylinder sleeve on the lower limb or to be pressed into.
