Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
A kind of fast assembling and disassembling device, comprise end cap 1, special spanner 2, type tube 3, type tube 3 two ends are provided with end cap 1, the center of circle of end cap 1 is provided with plug hole, described end cap 1 external cylindrical surface is provided with three axial pass troughs 101 that circumferentially direction is uniform, be provided with inclined-plane 102 between the right flank of each axial pass trough 101 and end cap 1 external cylindrical surface, the angle between inclined-plane 102 and end cap 1 end face is γ, angle γ 107 is 6 ~ 8 °; The height on the cut inclined-plane of right flank of each axial pass trough 101 is the thickness that Ha, height H a105 are greater than end cap 1/1st two, and the height on the cut inclined-plane of each end cap 1 external cylindrical surface is that Hb, height H b106 are greater than 1/2nd of height H a105; The center line that axial pass trough 101 is connected with the center of circle is provided with two one or two hand holes, and two one or two hand holes, on a concentric circles, two one or two hand holes are provided with handle 103, and the distance between two handles 103 cylindricals is length La104; Described special spanner 2 comprises handle 201 and the arm of force 202, the arm of force 202 be "
П" shape structure, the arm of force 202 is arranged on one end of handle 201, and the length of the arm of force 202 is Lb, and length Lb203 is more than or equal to length La104, and length L203 is less than the internal diameter of type tube 3.
During concrete enforcement, 1), when not changing type tube 3 structure, utilize existing three pin-and-holes in type tube 3 end, do three step-like straight pins, the small end of pin can produce interference fit with pin-and-hole, load in pin-and-hole by the small end of pin inside the hole of type tube 3, large end portion is exposed at outside pin-and-hole, can ensure to sell can not be thrown out of because of centrifugal force when type tube 3 rotates; 2) when, end cap 1 uses, put into asbestos pad in type tube 3 endoporus after, pick up the handle 103 on end cap 1, axial pass trough 101 on end cap 1 is aimed at the straight pin on type tube 3, end cap 1 is pushed in type tube 3 hole, clockwise rotary end cover 1, the inclined-plane 102 on end cap 1 is contacted with straight pin and wedging, suitably knock handle 103 with instrument again or with special spanner 2, end cap 1 tightened further, then completing the installation of end cap 1; 3), centrifugal casting time, type tube 3 turns clockwise, and due to the effect of inertia force, can keep wedging and can not unclamp between end cap 1 and straight pin; 4), dismounting end cap 1 time, oppositely knock or turn handle 3, end cap 1 being loosened, then catches handle 3 to rotate counterclockwise end cap 1 to axial pass trough 101 pairs of straight pins, end cap 1 can be taken out; 5), the angle of inclination on inclined-plane 102 is suitable, can not be too large, to ensure the self-locking performance after wedging, again can not be too little, so as not to end cap 1 need to turn over after larger angle could wedging, the length on inclined-plane 102 can be made like this to increase, operating efficiency reduction; 6), the height H a size of end cap 1 near axial pass trough 101 place be suitable, and making end cap 1 turn over suitable angle just can wedging, the position that namely straight pin wedging is suitable on inclined-plane 102; 7), the wedging power of three place's straight pins to end cap 1 should be made after end cap 1 wedging substantially equal, ensure end cap 1 evenly press seal pad, therefore, position and the size on three inclined-planes, place 102 of three straight pins and end cap should have good uniformity, and the processing on inclined-plane 102 should ensure certain precision.
Obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without the need to also giving all embodiments, and thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
