Advantage of the present invention and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the structural representation that the present invention uses state;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the I portion enlarged drawing of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 3, the present invention includes dismounting tube 1, cross support plate 2,4 adjusts screw 3, tension pulley 4, detent mechanism 5,3 radial location screws 6, dwangs 7, plays hoisting shackle 8, cross support plate 2 adopts welded-steel plate construction, fluting in the middle of the support plate, another piece support plate is inserted in and is welded to each other across in the groove.Dismounting tube 1 is the thin-walled that is provided with axial abutment joint 21 cylindrical member of cracking, and the trace that can adapt to flame circle 20 internal diameters of cylinder sleeve changes.The radially outer edge of tension pulley 4 is welded in dismounting tube 1 lower end, plays the supporting role to dismounting tube 1, can prevent from deformation takes place when dismounting tube 1 is stressed, increases the rigidity of dismounting tube 1.Cross recess is left in dismounting tube 1 upper end, and cross support plate 2 card is inserted in behind the cross recess cross support plate 2 and dismounting tube 1 is integrally welded, has improved the rigidity of cross support plate 2 and dismounting tube 1.
Detent mechanism 5 comprises locating piece 51, positioning sleeve 52, alignment pin 53, nut 9 welderings are adjusted even with three respectively in three outer ends of cross support plate 2, the 4th outer end of cross support plate 2 and locating piece 51 welderings connect, three are screwed in respectively on corresponding three adjustment nuts 9 in four adjustment screws 3, and another is adjusted screw 3 and is screwed on the locating piece 51.3 nut seats 11 of dismounting tube 1 inboard radial equipartition, positioning sleeve 52 is inlaid in the locating piece 51 downside endoporus 511, leaves the gap between the two, is convenient to adjust the relative position between diesel cylinder liner end face and the cross support plate 2.Alignment pin 53 passes locating piece 51, positioning sleeve 52, and its lower end embeds in the cylinder sleeve end face locating hole 10, and dismounting tube 1 and cross support plate 2 are positioned on diesel cylinder liner 30 end faces.
Uniform 3 backing pins 40 in dismounting tube 1 middle part are used for dismounting tube 1 axial location at flame circle 20.Tension pulley 4 radially is provided with 3 breach 41, breach 41 positions are corresponding with radial location screw 6 positions, be convenient to it is screwed in the nut seat 11, radial location screw 6 terminations put in the flame circle hole 201, dismounting tube 1 and flame circle 20 are linked into an integrated entity, and pulling dismounting tube 1 just can be extracted flame circle 20.Dwang 7 is fixedlyed connected with the tilting contiguous block 22 that is fixed on the cross support plate 2 by its threaded one end, a support plate upside of cross support plate 2 is provided with two installing holes that play hoisting shackle 8, wherein first installing hole, 231 central vertical are used for the flame circle of dismounting L diesel engine cylinder sleeve in dismounting tube 1 end face; Second installing hole, 232 centers and dismounting tube 1 axis oblique are for the flame circle 20 of dismounting V-type diesel cylinder sleeve.
During dismounting diesel cylinder liner flame circle, earlier cross support plate 2 is put into diesel cylinder liner together with dismounting tube 1, fall flame circle 20 upper ends until 3 backing pins 40 at dismounting tube 1 middle part.Again alignment pin 53 is passed locating piece 51, positioning sleeve 52, its lower end is embedded in the cylinder sleeve 30 end face locating holes 10, dismounting tube 1 is positioned on the diesel cylinder liner end face together with cross support plate 2.Adjusting screws 3 with four is screwed in three of cross support plate 2 terminations respectively and adjusts on the screwed hole of nut 9 and locating piece 51, adjustment screw 3 terminations are resisted against on the diesel cylinder liner end face, adjust four extension elongations of adjusting screw 3 respectively, make dismounting tube 1 axis as far as possible near flame circle 20 axis, be convenient to extract flame circle 20.Then 3 radial location screws 6 are passed corresponding nut seat 11 respectively, radial location screw 6 terminations put in the flame circle hole 201, make with flame circle 20 to link into an integrated entity.Again an end of dwang 7 is fixedlyed connected with cross support plate 2 upper end contiguous blocks 22 by screw thread.The lateral pin that plays hoisting shackle 8 is passed a support plate first installing hole 231 (being used for dismounting L diesel engine cylinder sleeve flame circle) or second installing hole 232 (being used for dismounting V-type diesel cylinder sleeve flame circle) of cross support plate 2, made hoisting shackle 8 and cross support plate 2 hinged.Utilize on manpower or the little heavy-duty hoisting equipment and mention hoisting shackle 8, when alignment pin 53 breaks away from the diesel cylinder liner end face, just can forward and reversely promote dwang 7 repeatedly continuously, increase the torque of rotating the flame circle; Carry flame circle 20 on while rotating, dismounting tube 1 drives the 20 forward and reverse rotations of flame circle by three radial location screws 6, makes flame circle 20 loosening gradually, just flame circle 20 can be taken apart from diesel cylinder liner 30.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
