The principle of work of the road sweeper lifting device specific embodiment that the utility model provides is:
As shown in Figure 1 and Figure 2, when road sweeper is in non-cleaning work state, the piston rod of oil cylinder 301 is in and stretches out most long status, oil cylinder 301 activation lever 201 rotates clockwise and is in clockwise maximum angle position, and lever 201 promotes snubber assembly 10 upwards to move together with refuse collector 60 by connecting rod 202. Refuse collector 60 upwards slides into distance extreme higher position, ground, it is ensured that refuse collector 60 bottom with ground clearance on ground, make road sweeper have the good property passed through when the state of traveling.
When road sweeper is in cleaning work state, the piston rod of oil cylinder 301 is in and shrinks the shortest state, oil cylinder 301 activation lever 201 rotates counterclockwise and is in counterclockwise maximum angle position, lever 201 contacts with shock-absorbing sleeve 403, shock-absorbing sleeve 403 is to lever 201 bumper and absorbing shocks and position-limiting action, lever 201 drives snubber assembly 10 to move downward together with refuse collector 60 by connecting rod 202, refuse collector 60 slides down to distance ground extreme lower position, ensure the contact good with ground bottom (as shown in Figure 3) of refuse collector 60, sweeping efficiency when guaranteeing that road sweeper is in working order.
In the road sweeper lifting device that the utility model provides, the cushioning principle of snubber assembly 10 specific embodiment is:
When road sweeper is in non-cleaning work state, the self gravitation of refuse collector 60 acts on the upper end of compression spring 102 by the substrate 101 of snubber assembly 10 and limiting plate 104, because the lower end of compression spring 102 is fixed on sliding plate 103 by stationary shaft 105, and the lower end of sliding plate 103 is supported by connecting rod 202 by hinged plate 110, so compression spring 102 is in compressed state.
When road sweeper is in cleaning work state, must contacting with ground bottom of refuse collector 60, namely the guide deflection sheave 501 on refuse collector 60 contacts with ground, as shown in Figure 3.
When the obstacle that the deceleration strip or other cleaning road surfaces that run into road protrude, the obstacle that the deceleration strip of road or other cleaning road surfaces are protruded will to the reactive force upwards of the walking wheel 603 on refuse collector 60, refuse collector 60 moves up under the effect of this reactive force, drive the substrate 101 on snubber assembly 10 and limiting plate 104 upwards to move simultaneously, upspring in the direction that compression spring 102 reduces to draught, to guarantee that refuse collector 60 can not be suspended in because upwards beating in the air. The effect of the cushion blocking 107 on snubber assembly 10 is when refuse collector 60 upwards moves too high, gives the buffering that refuse collector 60 is reverse; When the obstacle that the deceleration strip or other cleaning road surfaces of crossing road protrude, compression spring 102 returns to former compressed state again under the effect of refuse collector 60 self gravitation, it is achieved shock absorbing effect.
When running into the recessed road surface of road, refuse collector 60 loses road surface anchorage force, and under the effect of refuse collector 60 mass force, compression spring 102 continues to be compressed under the effect of refuse collector 60 mass force, absorbs moving load; When striding across the recessed road surface of road, compression spring 102 recovers former compressed state, it is achieved shock absorbing effect.
