Fig. 1 is a structural representation of the present invention.

Wherein, 1. lifting arm, 11. leverage components, 12. pedal I, 13. the balance pivot hole, 14. position and lock holes, 15. pins, 16. push rods, the tractive spring 17. lifting arm resets is 2. located latch hook, 21. right angle type pins, 22. swing arms, 23. hole, 24. skidway holes, 25. swing arms reset and use the tractive spring, 3. separation wedge, 31. voussoirs, 32. turning arms, 33. lever is given directions hole, 34. pedal II, the 35. turning arms tractive spring that resets.

The specific embodiment

The present invention will be further described below in conjunction with accompanying drawing and embodiment.

Among Fig. 1, lifting arm 1 is installed on the vertical clamped beam of level of road-sweeper, and lifting arm 1 is in the position that vertically slightly turns forward; Install on the pin 15 of lifting arm and separate wedge 3, separate turning arm on the wedge 3 tractive spring 35 1 ends that reset and hang on the lifting arm 1, the other end hangs over and separates on the wedge 3.This moment lifting arm 1 and separate wedge 3 and be cross-shaped, the pedal II34 of separation wedge 3 is positioned at horizontal level.Lifting arm 1 is a f shape leverage component 11, and pedal I12 is being fixed in the upper end of leverage component 11, and the middle section position of leverage component 11 has a balance pivot hole 13; There is a position and lock hole 14 pin 15 that separates wedge 3 to be installed between pedal I12 and the fulcrum hole 13 with one, lower end at f shape leverage component 11 is installed with fork-shaped push rod 16, the other end of push rod 16 is connected with the crane of road-sweeper by a lever, with fork-shaped push rod 16 parallel lifting arms in addition

Location latch hook 2 levels are installed in above-mentioned lifting arm 1 and the below of separating wedge 3 infalls, and it comprises a right angle type pin 21, and it is fixed on the middle section position of swing arm 22, forms a T-Type structure; Swing arm 22 left ends have a hole 23 with the vertical direction of road-sweeper vehicle frame assembling, so that be fixed on the crossbeam of road-sweeper front end, right-hand member is a Long Circle skidway hole 24, skidway hole 24 is through on the indication axle of lifting arm 1, thereby on the same horizontal cross fixed axis when installing with lifting arm 1, skidway hole 24 ends at swing arm 22 have a swing arm to reset with tractive spring 25, and swing arm resets and hangs on the beam of road-sweeper with tractive spring 25 other ends, is the horizontal cross position.

After lifting arm 1, separation wedge 3 and location latch hook 2 all install, separate the thin cutter of the voussoir 31 on the wedge 3, over against gap between lifting arm 1 and the location latch hook 2.

Separating wedge 3 is steel voussoirs 31 of oblique 30 degree of single face, and the position that takes over, the stage casing that it is fixed on turning arm 32 at distance voussoir 31 50MM place left, has a lever to give directions hole 33 on the turning arm 32, and indication hole 33 is through on the pin 15 of lifting arm 1; Nearly voussoir 31 ends at turning arm 32 have pedal II34, and the other end is equipped with the turning arm tractive spring 35 that resets.

The lifting action principle:

When forcing in the pedal I of lifting arm 1, lifting arm 1 is located lock hook 2 when promptly rotation arrives certain position before car external part inserts in the position and lock hole 14 of lifting arm 1, this moment, the pedal I end of lifting arm 1 was in the position of leaning forward most, also be the extreme higher position that road-sweeper rotating disc brush is raised built on stilts, finish promoting action.

When lifting arm 1 converts the decline state to by the lifting state, promptly be the effect that separates wedge 3.Force in when separating wedge 3 pedal II, separate wedge 3 and be rotated down.Voussoir 31 is compressed into the slit between lifting arm 1 and the location lock hook 2, pin 15 ends that force location lock hook 2 to stretch into lifting arm 1 withdraw from, simultaneously under lifting arm 1 lower end lifting arm resets the tractive of tractive spring 17, lifting arm 1 rotate, drives road-sweeper behind car rotating disc is brushed and is dropped to the position of cleaning ground.The state of step-down operation that Here it is.

More than be exactly that the lifting of using lever principle and tractive spring assembly realization road-sweeper rotating disc brush is handled.This apparatus structure is brief, and operation is reliable, is the manipulation device of economical and practical a kind of descending operation.
