Detailed description of the invention
As shown in Figure 1, this universal drainage plate bolt tightener, including the upper fastener 1 being oppositely arranged and lower fastener 2, this upper fastener 1 and lower fastener 2 can adopt ut socket, the bayonet-like structures of adjustable wrench can also be adopted, be respectively used to block the nuts and bolt on the positive and negative two sides of drainage plate. Described upper fastener 1 is rotatably installed in transmission case 3, described transmission case 3 is fixedly connected on the side of headstock 4, by bearing, main shaft 5 is installed in described headstock 4, described main shaft 5 is in transmission connection with drive motor 6, direct gear-engaged type transmission as shown in Figure 1 can be adopted, it would however also be possible to employ the transmission of other forms such as chain sprocket;Upper fastener 1 is fixedly connected with driven gear 7, the upper end of described main shaft 5 is installed with driving gear 8, described driven gear 7 is in transmission connection by the idle wheel 13 being arranged in transmission case 3 with driving gear 8, multiple idle wheels 13 are arranged in a row, driving gear 8 engages successively, so that can drive driven gear 7 and upper fastener 1 to rotate. The lower end of main shaft 5 is set with outer wall and sets threaded thread bush 9, and thread bush 9 is tubular structure, and its outer wall is provided with screw thread, and the lower end of main shaft 5 is inserted in thread bush 9; The lower end of described headstock 4, with longitudinally disposed chute 19, is slidably fitted with support arm 10 in described chute 19 so that it is can only longitudinal sliding motion and can not rotate. Support arm 10 is the rod-like structure be arrangeding in parallel with transmission case 3, described lower fastener 2 is arranged on the outer end of support arm 10, it is oppositely arranged with upper fastener 1, the inner of described support arm 10 is provided with the thread jacket 11 that engagement sleeves is contained on thread bush 9, time thread bush 9 rotates, thread jacket 11 and support arm 10 can move up and down therewith.
Described upper fastener 1 and lower fastener 2 are the movable bayonet formula structure of scalable bore, what described movable bayonet formula structure included being oppositely arranged determines clamp 21 and dynamic clamp 22, the described rear end determining clamp 21 is with the slide bar sleeve being perpendicular to bayonet socket direction, the barrel of described slide bar sleeve is provided with the sleeve window 25 of communication with cavity, the rear end of described dynamic clamp 22 is with the adjusting screw rod 23 being inserted in jack rod sleeve tube inner chamber, being set with adjusting nut 24 on described adjusting screw rod 23, described adjusting nut 24 is installed in sleeve window; The described lower end determining clamp 21 is provided with the mounting seat 26 of cylindrical-shaped structure. Rotating adjusting nut 24 can make adjusting screw rod 23 slide in slide bar sleeve, thus changing the gap determining between clamp 21 and dynamic clamp 22, it is achieved bayonet socket bore is adjustable, it is adaptable to the nut of different size.
It is provided with tension mechanism between described main shaft 5 and thread bush 9, described tension mechanism includes the shell fragment 51 being hinged on main shaft 5, the friction plate 52 being hinged on shell fragment 51 outer end, the outside of described friction plate 52 and thread bush 9 inwall are frictional fit, with the axle bed hole of axial distribution on the outer wall of main shaft 5, being provided with hinge in described axle bed hole, the inner of shell fragment 51 is fixedly connected on hinge. Time without External Force Acting, friction plate 52 is extruded by shell fragment 51 laterally, it is made to be close to the inwall of thread bush 9, utilize frictional force that both are locked, make thread bush 9 with main shaft 5 synchronous rotary, when the resistance of motion of thread bush 9 becomes big, time more than the frictional force of friction plate 52, skidding on thread bush 9 relative main 5, time main shaft 5 rotates, thread bush 9 does not rotate.
Described headstock 4 is fixedly mounted on the end of extension rod 12. This extension rod 12 adopts insulant to make, it is simple to remote hot line job.
Additionally being set with sliding bearing in the mounting seat of upper fastener 1, described sliding bearing is supported on the tank wall of transmission case 3, upper fastener 1 so can be avoided stuck so that it is operate more flexible, reduces the resistance of motion. Described driven gear 7 is fixedly mounted in the mounting seat of upper fastener 1.
As shown in Figure 1, Figure 3, the outer end of described support arm 10 is provided with fastener installing hole, and the mounting seat 26 of described lower fastener 2 is arranged in fastener installing hole; In this mounting seat 26, fixed cover is equipped with snap ring 14, the excircle of described snap ring 14 is uniformly distributed multiple positioning tooth 15, the inwall of described fastener installing hole is provided with the annular groove of coupling snap ring 14, described annular groove is provided with the hole, location of coupling positioning tooth 15, the width in this hole, location, slightly larger than the width of positioning tooth 15, makes lower fastener 2 can have certain movement clearance.Time lower fastener 2 is arranged in fastener installing hole, snap ring 14 is stuck in annular groove, it is possible to avoid lower fastener 2 to come off from fastener installing hole, and positioning tooth 15 is arranged in hole, location simultaneously, makes lower fastener 2 can freely swing in certain amplitude. So when lower fastener 2 packs into nut, there is certain free gap, it is easier to location.
During use, first manually adjust upper fastener 1 and the size of lower fastener 2 bore according to the specification of nut. Gap between upper fastener 1 and lower fastener 2 is slightly larger than the length of the bolt on drainage plate 20 so that it is can be respectively placed in the upper and lower both sides of screw bolt and nut by capturing position; Passing through remote control subsequently or be arranged on the switch activated drive motor 6 on extension rod 12, drive motor 6 drives main shaft 5 to rotate, and main shaft 5 upper end of rotation drives upper fastener 1 to rotate by driving gear 8, idle wheel 13 and driven gear 7. Meanwhile, the lower end of main shaft 5 drives support arm 10 up by servo-actuated thread bush 9, progressively reduces the gap between upper fastener 1 and lower fastener 2, until upper fastener 1 and the screw bolt and nut on lower fastener 2 respectively corresponding clamping drainage plate 20; Now owing to the up resistance of support arm 10 increases, the resistance of motion of thread bush 9 strengthens, when the resistance of motion of thread bush 9 more than frictional force between thread bush 9 and friction plate 52 time, thread bush 9 stops the rotation, and main shaft 5 continues to be rotated through upper fastener 1 by nut screwing clamping. After nut screwing clamping, handle drive motor 6 to reversely rotate, owing to main shaft 5 counter-rotating is applied to the pressure of friction plate 52 much larger than the pressure rotated forward by shell fragment 51, the frictional force now reversely rotated is bigger, and the resistance of motion is less when thread bush 9 counter-rotating, support arm 10 inverted running, can depart from from bolt. Additionally, time for avoiding main shaft 5 to reverse, the nut tightened is unclamped by upper fastener 1, the ratchet mechanism of single direction rotation can be set between main shaft 5 and driving gear 8, make driving gear 8 can only rotate forward with main shaft 5, when main shaft 5 reverses time, driving gear 8 does not rotate, so both when main shaft 5 rotates forward by nut screwing clamping, can prevent from coming off again nut in process and release.
The concrete structure of ratchet mechanism and operation principle are known technology, have various structures form directly to apply, are not discussed in detail here.
