Embodiment Construction

[0025] The following structural drawings and embodiments further illustrate the present invention.

[0026] Such as Figure 1-4 shown.

[0027] A method for avoiding obstacles with the side brush of a road sweeper, which transmits the impact force of the obstacle received by the anti-collision retaining ring or block on the side brush assembly to the side brush retractable oil cylinder and converts it into a pressure signal, The pressure signal is converted into an electrical signal through the pressure switch to control the side brush retractable oil cylinder to change the oil inlet direction, and then drive the side brush to make a compound movement backward and upward in the direction of brush retraction, so as to avoid obstacles.

[0028] A side brush anti-collision retractable mechanism of a road sweeper, comprising a side brush connecting rod 1, a side brush retractable oil cylinder 2, one end of the side brush connecting rod 1 is hinged to a rocker shaft 3 fixed on the...

Abstract

The invention relates to a method for side brush of sweep road car escaped from barrier and the anti-attack and retraction mechanism in hydraulic and electrically principle, which is aimed at the problem that side brush of prior sweep road car is destroyed easily, anti-attack mechanism is complex and does on escaped from barrier efficiently. It compounded by mechanism, electricity and hydraulics can make side brush retract immediately when attacked and escape from barrier so as to avoid abnormal failure of side brush as attacking force is transmitted to electrical signal to control inlet direction of oil cylinder by pressure switch and electrical control device. It is provided with sensitive feedback, safety, stability and simple structure.

Description

technical field [0001] The invention relates to a method for improving the safety of special vehicles and its anti-collision mechanism, in particular to a method for preventing the side brushes of a road sweeper from being damaged by a combination of hydraulic pressure and electric control and its anti-collision mechanism, specifically a A method for avoiding obstacles with a side brush of a road sweeper and an anti-collision retractable mechanism thereof. Background technique [0002] At present, with the development of the economy and the advancement of science and technology, the market has continuously put forward new requirements for the performance of the road sweeper, such as the side brush should have anti-collision function. When the road sweeper is cleaning, when the side brush encounters an obstacle or encounters a large resistance, it must be able to avoid the obstacle in time to ensure that the side brush mechanism is not damaged, and the cleaning task must be c...
