Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Refer to Fig. 1 to Fig. 3, a kind of chain tensioning device for hand barrow delivery system, comprise tensioner dolly 1, support the guide rail 5 of described tensioner dolly 1, the chain 6 for hand barrow delivery system transport hand barrow.
Guide rail 5 is fixed on truss with extending along the longitudinal direction, and tensioner dolly 1 only can be arranged on the guide rail 5 of the left and right sides along the longitudinal direction movably.In the present embodiment, guide rail 5 adopts angle steel.Tensioner dolly 1 is also connected with a screw rod extended back 2, described truss also extends in left-right direction and is installed with attaching parts 3, screw rod 2 is threaded the nut 4 be fixedly connected with attaching parts 3 by screw rod 2.In the present embodiment, attaching parts 3 also adopts angle steel, and the quantity of nut 4 has multiple.By fastening nut 4, screw rod 2 and attaching parts 3 are fixed together, and by the screwing position of setting nut 4 with screw rod 2, the expanding force of tensioner dolly 1 can be adjusted.As can be seen here, tensioner dolly of the present utility model 1 is movable just can tensioner chain 6, and is connected by attaching parts 3, nut 4 can be fixed by tensioner dolly 4 easily with screw rod 2, and structure is simple.The utility model increases the parts such as little angle steel, screw rod, nut in original hand barrow delivery system, just can realize the function of tensioner chain, not only save material, and easy to operate.
Refer to Fig. 2, tensioner dolly 1 comprises: sprocket wheel 11, left back side plate 12, be fixed on left back side plate 12 with support chains 6 run left back guide rail 13; Right back side plate 16, the right back guide rail 17 fixed and described right back side plate 16 runs with support chains 6.On truss, corresponding left back side plate 12 is provided with left front side plate 14, described left front side plate 14 is fixed with left front guide rail 15, has left splicing seams between left back guide rail 13 and left front guide rail 15.On truss, corresponding right back side plate 16 is provided with right front side plate 18, and right front side plate 18 is fixed with right front guide rail 19, has right splicing seams between right back guide rail 17 and right front guide rail 19.Left splicing seams and right splicing seams are staggered setting on the service direction of chain 6.After tensioner dolly 1 moves tensioner chain backward, left back guide rail 13 and left front guide rail 15 away from, right back guide rail 17 and right front guide rail 19 away from, the gap of left splicing seams and right splicing seams increases all thereupon.After tensioner dolly 1 moves forward, left back guide rail 13 is mutually close with left front guide rail 15, and right back guide rail 17 is mutually close with right front guide rail 19, and the gap of left splicing seams and right splicing seams reduces all thereupon.
Wherein, be also provided with major axis 20 between left back side plate 12 and described right back side plate 16, the end of major axis 20 is rotatably connected to roller 21, and roller 21 rolls and is arranged on guide rail 5.Sprocket wheel 11 is rotatably connected on sprocket shaft, and the two ends of sprocket shaft are rotatably connected to sprocket shaft roller, and sprocket shaft roller rolls and is arranged on guide rail 5, and like this, tensioner dolly 1 operates on left and right sides guide rail 5 by 4, front and back roller, mobile more steady.Left back side plate 12 is fixed between the left side of sprocket shaft and major axis 20, and right back side plate 16 is fixed between the right side of sprocket shaft and major axis 20.Wherein, described chain 6 is arranged at intervals with multiple chain roller set, each described chain roller set has the chain roller 61 be rotationally connected along the same axis, as shown in Figure 3.
When tensioner chain 6, tensioner dolly 1 and screw rod 2 are moved along guide rail 5 backward by roller 21, use nut 4 and attaching parts 3 screw rod 2 and attaching parts 3 to be fixed together, thus fixed by tensioner dolly 1 after tensioner.
The left splicing seams being staggered and arranging and right splicing seams is adopted in the utility model, can make the chain roller set on chain 6 operationally synchronization only have the chain roller of side to drop in splicing seams, on same axle two chain rollers are avoided all to fall into splicing seams, decrease vibrations when chain runs or be stuck, chain 6 being run more reliable and more stable.
