Abstract
The utility model relates to an automatic anti-slip control device for an all-hydraulic pneumatic tyred roller. The device comprises a controller (U2), wherein the controller (U2) is connected with a display (U1) through a bus, is connected with a velocity sensor I (U3) and a velocity sensor II (U4), and is also connected with a discrepancy switch (S1) which is a hold switch, the controller (U2) is connected with a proportion electromagnet of an electro-hydraulic proportional valve of a hydraulic pump (Y1), the hydraulic pump (Y1) is connected with a hydraulic motor I (Y2) and a hydraulic motor II (Y3) through a pipeline, and the controller (U2) is connected with a proportion electromagnet of an electro-hydraulic proportional valve of the hydraulic motor I (Y2) and the hydraulic motor II (Y3). By the automatic anti-slip control device for the all-hydraulic pneumatic tyred roller, the all-hydraulic pneumatic tyred roller can be effectively prevented from slipping.
Description
Technical field
The utility model relates to a kind of control device, especially relates to a kind of all-hydraulic rubber-tyred roller that is used for, and can prevent the control device that skids to belong to technical field of engineering machinery.
Background technology
All-hydraulic rubber-tyred roller deadweight is bigger, and ground is produced big pressure, and its type of drive generally adopts two kinds of form of structure that drive trailing wheel of fixed displacement motor.In operating process, because the road surface, certain side drive wheel of road roller is skidded; Hydraulic pump oil only flows on the wheel that is skidding, and drives the wheel skid and rotate at a high speed, and the motor of other driving wheel does not all rotate; Cause road roller not walk, the carrying out of influence construction.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and can effectively prevent the control device that tyre roller skids.
The purpose of the utility model is achieved in that the automatic anti-slip control device of a kind of all-hydraulic rubber-tyred roller; Said device includes controller; Said controller links to each other with display through bus, and said controller links to each other with velocity sensor two with velocity sensor one, also is connected with discrepancy switch on the said controller; Said discrepancy switch is a maintained switch; The proportion electro-magnet of electro-hydraulic proportional valve links to each other on said controller and the hydraulic pump, and said hydraulic pump links to each other with hydraulic motor two with hydraulic motor one through pipeline, and the proportion electro-magnet of electro-hydraulic proportional valve links to each other on said controller and hydraulic motor one and the hydraulic motor two.
Compared with prior art, the beneficial effect of the utility model is:
1, preventing effectively that tire is one-sided skids; 2, automatic controlling level is high; 3, guarantee construction quality and progress; 4, prolong the application life of hydraulic pump and motor; 5, operation is directly perceived, simple and convenient.

Fig. 1 is the structured flowchart of the automatic anti-slip control device of a kind of all-hydraulic rubber-tyred roller of the utility model.
Fig. 2 is the circuit block diagram of the automatic anti-slip control device of a kind of all-hydraulic rubber-tyred roller of the utility model.
Wherein:

Discrepancy switch S1.
The specific embodiment
Referring to Fig. 1 and Fig. 2; The automatic anti-slip control device of a kind of all-hydraulic rubber-tyred roller that the utility model relates to; Said device includes controller U2, and said controller U2 links to each other with display U1 through bus, and said controller U2 links to each other with velocity sensor two U4 with velocity sensor one U3; Said velocity sensor one U3 and velocity sensor two U4 are used to obtain the real-time speed of travel of road roller; Also be connected with discrepancy switch S1 on the said controller U2, said discrepancy switch S1 is a maintained switch, and said controller U2 links to each other with the proportion electro-magnet that a hydraulic pump Y1 goes up electro-hydraulic proportional valve; Said hydraulic pump Y1 links to each other with hydraulic motor two Y3 with hydraulic motor one Y2 through pipeline, and said controller U2 links to each other with the proportion electro-magnet that hydraulic motor two Y3 go up electro-hydraulic proportional valve with hydraulic motor one Y2.
When system works, the signal that controller U2 provides through velocity sensor is calculated the travel speed of current each driving wheel of complete machine by inner equation; And judge whether discrepancy switch S1 moves; Display U1 can point out current complete machine travel speed and anti-slip to control duty automatically, if the complete machine side is during owing to the different phenomenon of wheel-slip or the unsettled both sides vehicle wheel rotational speed that produces, as long as the operator presses the discrepancy switch S1 of automatic anti-slip; Display U1 goes up anti-slip control icon meeting Gao Liang; The mode of operation of prompting user this moment, controller (U2) will make its swash plate increase to the minimizing PWM value that proportion electro-magnet receives on the hydraulic motor of a side drive wheel of skidding; Reduce its output torque of side hydraulic motor that skids through the oil inlet quantity of regulating corresponding hydraulic motor; Not enough until Torque Performance of Hydraulic Motor so that the driving wheel of hypervelocity skids, to reach skidding of the one-sided hydraulic motor of elimination, guarantee that complete machine goes steadily.After the travel conditions of vehicle recovered normally, the operator moved back to initial position with discrepancy switch S1, and anti-slip control promptly quits work automatically.
