Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of A in Fig. 1:
Fig. 3 is the partial enlarged drawing of B in Fig. 1;
Fig. 4 is that the utility model is at the partial enlarged drawing (hiding clamp nut) of stage clip position.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Referring to Fig. 1 ~ Fig. 4, road sweeper rear-guard chain regulating system of the present utility model, comprise chassis 1, chassis 1 upper surface is provided with rear axle assy 2, the two ends of rear axle assy 2 are provided with rear-guard drive sprocket 3, described rear-guard drive sprocket 3 drives rear wheel assembly 41 by rear-guard driving chain 4, on described chassis 1, be also provided with back axle supporting seat 5, the driving shaft 21 of rear axle assy 2 is set up in the U groove 51 of back axle supporting seat 5, on driving shaft 21, be installed with junction plate 6, after having back axle trip bolt 7 through the strip hole 52 on described junction plate 6 and back axle supporting seat 5, by clamp nut 8, locked, back axle trip bolt 7 has certain activity surplus in strip hole 52, the needs that regulate to adapt to the tensioning of rear-guard driving chain, also include lift adjustment screw rod 9, on described driving shaft 21, be installed with back axle support member 10, on back axle support member 10, be provided with screw 101, described lift adjustment screw rod 9 is connected on described chassis 1 through after this screw 101, on the lift adjustment screw rod 9 between chassis 1 and back axle support member 10, be equipped with stage clip 11, the two ends of described stage clip 11 respectively with chassis 1 and back axle support member 10 butts, preferably, described lift adjustment screw rod 9 is four symmetrical surroundings that are arranged in described driving shaft 21.
