In the figure:

1. the device comprises a base I, a base 2, an anti-collision rotating block, a nitrogen spring 3, a sheath pull wire 4, a base II, an adjusting screw 6, a tension spring 7, a rotating shaft 8, a lifting arm 9 and a nozzle 10.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, the nozzle lifting device includes a base, a lifting arm 9, a bump protection rotating block 2, a sheath pulling wire 4, and a nozzle 10 disposed at a lower end of the lifting arm 9.

The upper end of lifing arm 9 and anticollision commentaries on classics piece 2 all articulate on the base through pivot 8, and the lower extreme of anticollision commentaries on classics piece 2 is aligned around with lifing arm 9, is equipped with nitrogen spring 3 between the upper end of anticollision commentaries on classics piece 2 and the base II 5, is equipped with extension spring 7 between the upper portion of lifing arm and the base I1.

Base I1 and base II 5 are located the both sides of lifing arm respectively, and two bases are all established on environmental protection vehicle chassis, or directly are two parts on vehicle chassis.

The anti-collision rotating block 2 is a plate structure, a lug is arranged on the plate structure, and the lug is connected with the rotating shaft. The lower ends of the tension spring 7 and the anti-collision rotating block are positioned on the same side of the lifting arm. And a sheath pull wire for driving the lifting arm to lift is arranged on the base II, the lower end of the sheath pull wire is connected with the lifting arm, and the sheath pull wire and the tension spring are respectively positioned on two sides of the lifting arm.

The initial state of anticollision commentaries on classics piece is that the lifing arm is vertical with the laminating lifing arm of anticollision commentaries on classics piece lower extreme. The lower extreme of anticollision commentaries on classics piece corresponds the lifing arm and is equipped with the rubber buffer block, reduces the lifing arm striking. Furthermore, the lower extreme of anticollision commentaries on classics piece is equipped with and is used for the adjusting screw 6 to the spacing regulation of lifing arm.

The invention integrates the mechanical connecting rod transmission, the application of the mechanical pendulum bob and the push rod, has compact and stable structure, has flexible avoidance and anti-collision functions, ensures stable and reliable work under various complex conditions, and forms a brand new and ingenious structure.

Anticollision commentaries on classics piece 2 and lifing arm 9 are articulated with pivot 8 respectively, and pivot 8 is fixed with chassis or base to make lifing arm 9 can revolute 8 rotatory lifts of pivot, and secondly, the sheath is acted as go-between 4 and is fixed on base 5, and is articulated fixed with lifing arm 9, and at this moment, when the sheath is acted as go-between 4 and is received external force and stretched, lifing arm 9 is rotatory together with nozzle 10 and is risen. Conversely, when the sheath pull wire 4 is not stressed, the lifting arm 9 rotates downwards under the action of the tension spring 7.

When the nozzle for the forward running of the vehicle meets an obstacle, the lifting arm and the nozzle rotate clockwise and backward to avoid collision, and when the nozzle for the backward running of the vehicle meets the obstacle, the lifting arm and the nozzle rotate anticlockwise and forward to avoid collision, so that the collision of the obstacle to the nozzle can be effectively reduced, and the stable and reliable work under various complex conditions is guaranteed; and the structure is compact, and the arrangement is convenient.

The above-mentioned features are merely for describing preferred embodiments of the present invention and may be arbitrarily combined to form a plurality of embodiments of the present invention.

The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution, or to apply the inventive concept and solution directly to other applications without modification.
