Abstract
The utility model relates to a suction nozzle suspension device for a sweeping car. A pulling force follow-up device is arranged on a chassis (1), one end of the pulling force follow-up device is supported on a chassis wheel shaft (2) by a post rod (3), and the other end suspends a suction nozzle (10) by a lifting rope (9). The pulling force follow-up device is that the chassis of a sweeping car is provided side by side with three swing arms (4), and the right angle ends (6) of the swing arms are hinged on the chassis by pin shafts; The horizontal rod end of one front swing arm is hinged to the upper end of the post rod, and the lower end of the post rod is supported on an outer shell of the chassis wheel shaft; the horizontal rod ends of the two back swing arms are connected to the lifting rope suspending the suction nozzle; or the chassis of the sweeping car is provided side by side with a swing arm and two pulleys (12), and the lifting rope suspending the suction nozzle is connected to a vertical rod of the swing arm by the pulleys; or the chassis of the sweeping car is provided side by side with three oil cylinders which are communicated with each other by an oil pipe to obtain the pulling function of the follow-up device. The utility model does not affect the suspension pulling force for the suction nozzle because of the chassis descending, and thus, the service life of a supporting wheel of the suction nozzle is prolonged.
Description
Technical field
The utility model relates to a kind of sweeping machine suction nozzle-hanging device.
Technical background
At present, the suction nozzle installed down of sweeping machine all is to adopt chain or steel wire, spring to be suspended on the chassis.Owing to the suction of rubbish, the chassis can descend gradually in the cleaning work process, and at this moment, the chassis also can reduce gradually to the pulling force of suction nozzle, make the weight of suction nozzle lean on the bogie wheel under the suction nozzle to support substantially, so the bogie wheel wearing and tearing is very fast, and application life is short.
Summary of the invention
The purpose of this utility model is will provide a kind of not influence the suction nozzle of sweeping car suspension arrangement of pulling force because of the chassis descends.
The technical solution of the utility model is: a pulling force hunting gear is installed on the chassis, and of this device is bearing on the wheel shaft of chassis by push rod, and the other end hangs suction nozzle by lifting rope.
The utility model influence suspension pulling force to suction nozzle because of the chassis descends, prolonged the suction nozzle bogie wheel application life, thereby the operating cost of saving sweeping machine.
Description of drawings
Fig. 1,2,3 is the structure principle chart of 3 embodiment of the utility model.
Among the figure 1, the chassis, 2, the chassis wheel shaft, 3, push rod, 4, swing arm, 5, swing arm montant end, 6, swing arm right angle end, 7, the horizontal rod end of swing arm, 8, stay cord, 9, lifting rope, 10, suction nozzle, 11, bogie wheel, 12, pulley, 13,14,15 oil cylinders, 16, oil pipe.
The specific embodiment
Introduce the utility model below in conjunction with drawings and Examples.
Embodiment 1: with reference to Fig. 1,3 swing arms 4 are installed on the chassis 1 of sweeping machine side by side, swing arm right angle end 6 is hinged on the chassis by bearing pin, the front horizontal rod end 7 of a swing arm is hinged on push rod 3 upper ends, the push rod lower end is supported on chassis wheel shaft 2 shells, and the horizontal rod end of latter two swing arm is ined succession and hung the lifting rope 9 of suction nozzle 10.3 swing arm montant ends 5 are connected as a single entity by stay cord 8.
Embodiment 2: with reference to Fig. 2, a swing arm 4, two pulleys 12 are installed successively side by side on the chassis 1 of sweeping machine.Two lifting ropes 9 that hang suction nozzle are connected on the montant end 5 of swing arm 4 by pulley 12.
Embodiment 3: with reference to Fig. 3, on the chassis 1 of sweeping machine, oil cylinder 13,14,15 is installed side by side, the piston rod of oil cylinder 13 connects push rod 3.The rear end of oil cylinder 13 is communicated with the rod end of oil cylinder 14 by oil pipe 16, and the rod end of oil cylinder 13 is communicated with by the rear end of oil pipe with oil cylinder 14; The rear end of oil cylinder 14 is communicated with by the rear end of oil pipe with oil cylinder 15, and the rod end of oil cylinder 14 is communicated with by the rod end of oil pipe with oil cylinder 15.
Above-mentioned 3 embodiment respectively by the effect of swing arm, pulley, oil cylinder, remain unchanged the pulling force of the 9 pairs of suction nozzles of lifting rope that hang suction nozzle 10, the not influence of a small amount of lifting of suspension chassis of friction on bogie wheel 11 and ground.
