Embodiment
Below, in conjunction with accompanying drawing preferred implementation of the present invention is elaborated.
For the package assembly of pressing wheel assembly for connecting pipes of the present invention is described, at first combine Fig. 2 that the structure of pinch roller is elaborated.
As shown in Figure 2, the pinch roller 10 of pressing wheel assembly for connecting pipes of the present invention comprises interior wheel portion 11, foreign steamer portion 12 and horizontal part 13; Wherein, the upper end of said interior wheel portion 11 and the upper end of foreign steamer portion 12 are connected through said horizontal part 13; The upper end of wheel portion 11 is formed with mounting groove 14 and leg hole 15 in said; Said horizontal part 13 is formed with bolt hole 16; Said foreign steamer portion 12 is formed with bolt assembly department 17.
On the pinch roller of said structure, according to other parts of following method mounting pipe pressing wheel assembly for connecting, to form an assembly body unit.
Like Fig. 3 and shown in Figure 4, pressing wheel assembly for connecting pipes of the present invention also comprises break 20, finger 30, support ring 40 and connecting bolt 60; Wherein, said break 20 comprises ring portion 21 and shank 22, in the mounting groove 14 that this ring portion 21 and shank 22 are installed on pinch roller 10 respectively and the leg hole 15, thereby makes the shank 22 of break 20 protrude in the inside of pinch roller 10; Said finger 30 is installed on the ring portion 21 of said break 20, and said finger 30 inserts in the hollow portion 42 of the cylindrical part 41 that is formed on support ring 40; Said support ring 40 comprises flange 44, and this flange 44 is fixed in the horizontal part 13 of pinch roller 10 through bolt 51 and nut 52; Said connecting bolt 60 is installed on the bolt assembly department 17 of pinch roller 10 through nut 61.
The lower end of the interior wheel portion 11 of said pinch roller 10 is outstanding to inside; And should in the lower end of wheel portion 11 play the effect of press ring that extruding is arranged at the closed loop 80 (please refer to Fig. 5) of socket pipe 70 (please refer to Fig. 5) that is used for; And; In Fig. 2 and Fig. 3, though only show three bolt assembly departments 17 and bolt hole 16 respectively, the quantity of said bolt assembly department 17 and bolt hole 16 is to adjust according to the size of pinch roller.
Be formed with a plurality of said shanks 22 on the ring portion 21 of said break 20.In Fig. 2 and Fig. 3, though only show three shanks 22, its quantity is to adjust according to the size of pinch roller.
Said finger 30 is connected to form annular through a plurality of sheets 31 and elastomer 34 with the mode of alternately arranging each other, and the inner side surface of said sheet 31 is formed with limit pawl 32, and outer side surface is formed with rake 33.According to said structure, even the connecting tube 90 (please refer to Fig. 5) that is clamped by finger 30 becomes ellipse because of receiving external force, the also available uniform power of said finger 30 clamps connecting tube 90.
Said elastomer 34 can be processed by rubber or resilient synthetic resin, and can have the side section identical with the side section of piece sheet 31.
Said support ring 40 forms the cylindrical part 41 with certain altitude h for finger 30 is inserted in the hollow portion 42; For making the combination mutual noninterference of bolt 51 and connecting bolt 60, be formed with groove 43 on the outer circumferential face of said cylindrical part 41; The lower end of said cylindrical part 41 forms flange 44; Be formed with bolt hole 45 that is used for inserting bolt 51 and the bolt assembly department 46 that is used to install connecting bolt 60 with groove 43 corresponding positions on the said flange 44; This bolt assembly department 46 is arranged to the shape of aliging with the bolt assembly department 17 of pinch roller 10; Be formed with plane of inclination 47 around the said hollow portion 42; The inside lower end of said cylindrical part 41 is formed with shank groove 48.
The pressing wheel assembly for connecting pipes of the present invention of said structure, because need not to overturn said pinch roller 10 for assembling, therefore can be under the state that break 20 and finger 30 are installed on the pinch roller 10; Support ring 40 is fixed in pinch roller 10; Thereby in assembling process, locate the mounting point of said break 20 and finger 30 easily, make break 20 and finger 30 be difficult for breaking away from the mounting point; Thereby be convenient to assembling; And can, factory be transported to operation field with assembled state, thereby be convenient to use after accomplish assembling at operation field.
Below, explain that in conjunction with Fig. 5 and Fig. 6 utilization connects the manufacturing process of two pipes through the pressing wheel assembly for connecting pipes of the present invention of said process assembling.
(A) closed loop 80 is installed in the rake of socket pipe 70.
(B) pressing wheel assembly for connecting pipes 100 of the present invention is inserted on the connecting tube 90.
(C) front end with connecting tube 90 is inserted on the closed loop 80 that is installed on socket pipe 70.
(D) after the pressing wheel assembly for connecting pipes of the present invention 100 that will insert connecting tube 90 furthers socket pipe 70, the mounting part of connecting bolt 60 lower ends is mounted on the lower end of the flange 73 of socket pipe 70, on connecting bolt 60, combine nut 61 again.
(E) afterwards, tighten said nut 61 and can accomplish assembling.At this moment; As shown in Figure 6; Because of the effect of connecting bolt 60, pinch roller 10 will be to socket pipe 70 1 side shiftings, and the shank 22 of break 20 will insert in the shank groove 48 of support ring 40; Said break 20 is jack-up finger 30, thus said finger 30 receive support ring 40 plane of inclination 47 effect and clamp connecting tube 90.In addition, the lower end extruding closed loop 80 of the interior wheel portion 11 of pinch roller 10, the slit between closed loop 80 sealing socket pipes 70 and the connecting tube 90; And; When the shank 22 of break 20 stopped at the shank groove 48 of support ring 40, then the shank 22 because of said break 20 was supported by the flange 73 of socket pipe 70, so when fastening nut 61; Can prevent pinch roller 10 too to socket pipe 70 1 side shiftings, thereby the interior wheel portion 11 that prevents said pinch roller 10 too presses down closed loop 80.
As stated the assembling pressing wheel assembly for connecting pipes of the present invention in, as shown in Figure 7, though because of winter low excessively temperature the length of connecting tube 90 is dwindled; Or because of pipe interior generation abnormal pressure moves connecting tube 90 to the direction of arrow 95 in socket pipe 70, pinch roller 10 also can firmly be assembled in socket pipe 70 through connecting bolt 60, therefore needn't worry that the distance between pinch roller 10 and the socket pipe 70 changes; And; As long as pinch roller 10 do not come off, the interior wheel portion 11 of pinch roller 10 just can continue to push closed loop 80, therefore; Even connecting tube 90 is moved, can the sealing function of closed loop 80 not exerted an influence yet.In addition; Because of the finger 30 that clamps connecting tube 90 is shunk by the effect of the plane of inclination 47 of support ring 40; Therefore can suppress connecting tube 90 to greatest extent and move backward, and, because of under the state of the bolt assembly department 17 of the bolt assembly department 46 of alignment support ring 40 and pinch roller 10; Strengthened the combination of support ring 40 and pinch roller 10 through connecting bolt 60 and nut 61, thereby can prevent that support ring 40 from getting loose from pinch roller 10.
