Driving mechanism, has drive rod, and connection sliding block 3 is held in ejecting of drive rod, is used for driving slide block 3 to synchronize continuous moving on two tracks 2, with tightening belt；
Detent mechanism, has location bar 7 and locking piece 8, one end connection sliding block 3 of location bar 7, the other end is free end, can along being parallel to the direction continuous moving that drive rod ejects under the drive of slide block 3, locking piece 8 is for being locked in predeterminated position by location bar 7, with lock slider 3.
The tensioner of said structure, in space limited in track groups, is separately provided driving mechanism and detent mechanism.Wherein, the end that ejects of the drive rod of driving mechanism is directly connected with slide block 3；Detent mechanism has location bar 7 and locking piece 8, one end connection sliding block 3 of location bar 7, the other end is free end, the direction continuous moving that location bar 7 ejects along the drive rod being parallel to driving mechanism, locking piece 8 is for being locked in predeterminated position by location bar 7, with lock slider 3.Namely, location bar 7 is separate with drive rod and be arranged in parallel, go up in the horizontal direction, increase the installing space of driving mechanism, the driving mechanism of bigger stroke just can be set in this confined space, the length positioning bar 7 accordingly also is able to the longer of setting, when driving roller shifting, without changing driving mechanism position in track groups, cylinder 4 just can be moved to the position of tightening belt, and by locking piece 8, location bar 7 is locked in predetermined position, belt is made to be in tensioning state, thus simplifying the operation of tensioner tightening belt process, it is easy to the timely tightening belt of tensioner, and then improve the efficiency of tensioner tightening belt.
As preferred embodiment, above-mentioned tensioner, also include limiting plate 6, its two ends are individually fixed on a track 2, have the first pilot hole 61, and one end of location bar 7 is connected on slide block 3 through the first pilot hole 61；Locking piece 8 is for being locked in limiting plate 6 by location bar 7.When needs tightening belt, driving mechanism drives cylinder 4 continuous moving to the position of tightening belt, limiting plate 6 itself is not moved, only location bar 7 need to be fixed on limiting plate 6 by locking piece 8, just can so that cylinder 4 keeps the state of tightening belt, without as in prior art when the distance that cylinder 4 moves more than location bar 7 length time, need the position of mobile limiting plate 6, can location bar 7 be limited on limiting plate 6, and then the position of positioning rolls 4, consequently facilitating the operation of tightening belt.
As further preferred embodiment, locking piece 8 includes the external screw thread being arranged on the outer wall of location bar 7, and it being set in two nuts on the bar 7 of location, two nuts bear against on limiting plate 6, and by location bar 7 being locked on limiting plate 6 with externally threaded cooperation.When needs are to belt tension, only the nut at limiting plate 6 two ends need to be unclamped, when hydraulic cylinder 5 drives cylinder 4 to move to tightening belt position, by two nut screwing clampings, the two ends that location bar 7 just can be in the first pilot hole 61 are locked on limiting plate 6, so that cylinder 4 keeps tensioning state；And nut with externally threaded coordinate can realize location bar 7 slides on track 2 take office meaning position time, the state locked at any time, so make tensioner be easy to operate.
Variant embodiment as locking piece, the screwed hole being opened on the bar 7 of location can also be included, screwed pin and be opened in the groove on track 2 sidewall in outside wall surface, when positioning bar 7 and sliding into desired location, alignment pin is located in screwed hole, fixing and one end is coordinated to be positioned at the groove of track 2 with screwed hole, thus being locked on track 2 by location bar 7.Or other locking pieces 8 of the prior art, as long as at any time location bar 7 can be locked in the sliding position place on track 2, keep cylinder 4 to be in tightening belt state.
As further preferred embodiment, location bar 7 is two, and when drive rod ejects, two location bars 7 are arranged on the both sides of drive rod relative to the axisymmetrical of drive rod.Symmetrically arranged two location bars 7, it is simple to move to tightening belt position at cylinder 4, it is possible to slide block 3 is locked in this position more firmly, and cylinder 4 can more securely keep tightening belt state.
As deformation, the number of location bar 7 can also be one, three, four, five etc., as long as can pass through to position bar 7 cylinder 4 is securely positioned in the position being in tightening belt state, the number specifically arranging location bar 7 need to be determined according to actually used situation.
As more preferably preferred embodiment, limiting plate 6 arranging the second pilot hole 62, drive rod stretches out from the second pilot hole 62 and is connected to slide block 3 so that the more compact structure that tensioner is arranged on track 2.
As further preferred embodiment, also including fixing seat 9, the two ends of fixing seat 9 overlap respectively and are fixed on a track 2；Being provided with the 3rd pilot hole 91 on fixing seat 9, driving mechanism is fixed on fixing seat 9, and the free end of location bar 7 is removably set in the 3rd pilot hole 91.When positioning bar 7 along with slide block 3 continuous moving together, free end can move in the 3rd pilot hole 91, further such that the compact conformation of whole tensioner.
As in figure 2 it is shown, as the preferred implementation of driving mechanism, driving mechanism is hydraulic cylinder 5, hydraulic cylinder 5 is arranged on fixing seat 9, and the piston rod of hydraulic cylinder 5 is drive rod.It is further preferred that also sheathed dust cover 10 on one end of the close slide block 3 of drive rod, it is prevented that after drive rod stretches out, directly and extraneous contact, extraneous dust or foreign material drop on drive rod, affect the properly functioning of drive rod.
As deformation, driving mechanism can also be other driving device, for instance motor, the telescopic shaft of motor is as drive rod；Or cylinder etc., as long as can drive slide block 3 mobile on track 2.
As shown in figures 1 and 3, as the preferred implementation of cylinder 4 with the fixed form of slide block 3, slide block 3 being offered installing hole 31, arranges bearing block 11 in installing hole 31, bearing block 11 is installed bearing 12, cylinder 4 is located in the endoporus of bearing 12.When slide block 3 moves, cylinder 4 moves along with slide block 3, when slide block 3 move to cylinder 4 can the position of tightening belt time, slide block 3 maintains static, and cylinder 4 rotates in bearing 12, and then makes belt constantly rotate on cylinder 4, it is achieved transfer function.In addition, cylinder 4 can also adopt other modes of being rotatably connected of the prior art to be arranged on slide block 3.
As the best preferred embodiment, track groups is two, is separately positioned on the two side, front and back of framework 1；Slide block 3 is two, and a slide block 3 is connected to one end of cylinder 4, and another slide block 3 is connected to the other end of cylinder 4；Driving mechanism is two sets, and a set of driving mechanism is for driving the slide block 3 being connected to cylinder 4 one end, and another set of driving mechanism is for driving the slide block 3 being connected to cylinder 4 other end；Detent mechanism is two sets, for two slide blocks 3 of locking respectively.Now, cylinder 4 is before and after framework 1 between wall, the two ends of cylinder 4 are respectively provided with in a track groups, and respectively through a slide block 3, a set of driving mechanism and a set of detent mechanism, the two ends of cylinder 4 are separately positioned on the front and back wall of framework 1, make the cylinder 4 can more smoothly by belt tension.
