Abstract
The invention belongs to the field of pavement engineering machinery, and relates to a self-feedback floating scraping system of a pavement milling machine. The self-feedback floating scraping system comprises a scraping plate and a control system, wherein the scraping plate is arranged on the lower part of a turning body of the pavement milling machine and can lift by being driven by a scraping plate oil cylinder; the control system is used for controlling the lifting of the scraping plate, and comprises a pressure sensor which is arranged on the scraping plate and can detect ground pressure of the scraping plate; the detection signal output end of the pressure sensor is connected to a CPU (Central Processing Unit) capable of processing detection data; and the control instruction output end of the CPU is connected to a scraping plate valve group capable of controlling the action of the scraping plate oil cylinder. The self-feedback floating scraping system disclosed by the invention can keep the appropriate ground pressure all the time for milling in a pulling and scraping operation process by detecting and regulating the ground pressure of the scraping plate in real time, thereby being suitable for the change of pavements with different terrains and improving the construction effect and efficiency.
Description
Technical field
The invention belongs to field of road engineering machinery, relate 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 promptly 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 excessive scraping on the other hand again, make milling work produce excessive advance resistance, so both uneconomical, environmental protection ground, also operating efficiency be can reduce, even work, damage machine influenced.
Summary of the invention
Technical problem to be solved by this invention 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 invention 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 the control system that is used for controlling the 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 present invention is by to the 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 embodiment of the invention.
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 the control system that is used for controlling 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.
