Abstract
The utility model belongs to road construction machinery and relates to a self-feedback floating scraping system for a road milling machine. The system comprises a scraper arranged at the lower part of a road milling machine body, wherein the scraper can be driven to go up and down through a scraper cylinder; the system also comprises a control system for controlling the scraper to go up and down; the control system comprises a pressure sensor which is arranged on the scraper and can detect the size of the grounding pressure of the scraper; the detection signal output end of the pressure sensor is connected with at least central processing unit (CPU) which can process the detection data; and the control instruction output end of the CPU is connected to a scraper valve group which can control the action of the scraper cylinder. The scraper grounding pressure is detected and adjusted in real time, so that proper grounding pressure can be always kept in the scraping operation process of the road milling machine, the road milling machine can be adapted to the change of the road at different terrains, and the construction effect and efficiency are improved.
Description
Technical field
The utility model belongs to field of road engineering machinery, relates to the unsteady scraper system of a kind of pavement milling machine self feed back.
Background technology
The course of work of pavement milling machine need be drawn the intact road surface of milling and be scraped the purpose that operation reaches the cleaning road surface, assembles waste material.Existing milling machine generally adopts simply to draw scrapes operation form, and a cover scraper namely is installed at the milling and planing drum rear portion, the scraper natural grounding, and ground pressure immobilizes.This mode can only merely realize the scraper function, and in the operating mode of milling machine complexity without any the adjusting adaptive capacity.Thereby cause uncontrollable to the cleannes of scraper on the one hand, might cause the excessive scraping to ground on the other hand again, make milling work produce excessive advance resistance, so both uneconomical, environmental protection, also operating efficiency be can reduce, even work, damage machine influenced.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of ground pressure that can adjust the operation of pavement milling machine scraper in real time, the unsteady scraper system of the pavement milling machine self feed back that efficiency of construction is high and construction quality is good.
The unsteady scraper system of pavement milling machine self feed back of the present utility model includes the scraper plate that is installed in the pavement milling machine body bottom section, and scraper plate can be by its lifting of scraper plate hydraulic oil cylinder driving, to change the ground pressure of scraper plate lower end; This system also includes to control the control system of scraper plate lifting; Described control system includes the pressure sensor that is installed on the scraper plate and can detects scraper plate ground pressure size; The detection signal output of described pressure sensor is connected to one can handle the CPU element that detects data, the control instruction output of described CPU element be connected to can control the scraper plate cylinder action scrape the plate valve group, thereby can control the scraper plate lift adjustment in real time according to the detection signal of pressure sensor.
Described CPU element also includes the control instruction output that is connected with the pavement milling machine traveling control system, thereby can adjust the speed of travel according to the size of ground pressure, makes it mutual coupling.
The utility model is by to real-time detection and the adjusting of scraper plate ground pressure, can make milling keep more suitable ground pressure in the operation process eventually drawing to scrape, thereby can adapt to the variation on different terrain road surface, improved construction effect and efficient.
Description of drawings
Fig. 1 is the system architecture schematic diagram of the utility model embodiment.
The specific embodiment
As shown in the figure, the unsteady scraper system of this pavement milling machine self feed back includes the scraper plate 2 that is installed in road-surface milling locomotive 1 body bottom, and scraper plate can drive its liftings by scraper plate oil cylinder 3, to change the ground pressure of scraper plate lower end; This system also includes to control the control system of scraper plate 2 liftings; Described control system includes the pressure sensor 4 that is installed on the scraper plate and can detects scraper plate ground pressure size; The detection signal output of described pressure sensor is connected to one can handle the CPU element 5 that detects data, the control instruction output of described CPU element be connected to can control the scraper plate cylinder action scrape plate valve group 6, thereby can control the scraper plate lift adjustment in real time according to the detection signal of pressure sensor.Described CPU element 5 also includes the control instruction output that is connected with pavement milling machine traveling control system 7, thereby can adjust the speed of travel according to the size of ground pressure, makes it mutual coupling.
