Abstract
The invention provides a sand spreading electrical control device for an internal combustion locomotive. The sand spreading electrical control device for the internal combustion locomotive comprises a pressure relay, a forward sand spreading electromagnetic valve, a reverse sand spreading electromagnetic valve and a control circuit, wherein the control circuit comprises two parallel branches; one branch comprises the pressure relay, a delay coil and a normally-open contact which are serially connected; the other branch comprises a manual control circuit, a sand spreading circuit and a master switch which are serially connected; and one end of a circuit formed by connecting the normally-closed contact and the delay normally-closed contact in parallel is connected between the manual control circuit and the sand spreading circuit, and the other end of the circuit is connected between the pressure relay and the delay coil or between the pressure relay and the normally-open contact. In an emergency braking state, the pressure of a locomotive tube increases, the pressure relay is closed, and sands are spread; when a speed sensor detects that the rotation speed of a locomotive wheel is lower than a preset valve, the delay normally-closed contact is closed after a set time, and sand spreading stops; and the sand spreading amount is controlled by a delay relay, and when the locomotive has a low speed, the sands are not spread, thus saving resources, protecting environment and avoiding potential safety hazards.
Description
Technical field
The present invention relates to the diesel locomotive electronic control technology, relate in particular to a kind of diesel locomotive stucco electrical controller.
Background technology
For giving full play to the locomotive adhesive tractive effort, prevent wheel slipping and slide that the DF7 series internal combustion locomotive is provided with sanding device; Sanding device is comprised of electromagnetic valve, sander and pipeline.The driver controls stucco by foot-operated switch, when perhaps the locomotive control microcomputer detects wheel pair idling, and automatically stucco.
The principle of existing automatically controlled sanding device as shown in Figure 1, the stucco control process is as follows:
1) by manual control circuit control stucco, left food switch 1 and right threading switch 2 are housed on the operating console driver pedal, during one of them switch closure, there is one to get electronic work in forward electromagnetic valve and the reverse electromagnetic valve, the pressure air that comes from total reservoir enters sander, by sand pipe, sand blasting is spread on the rail level, forward electromagnetic valve and reverse electromagnetic valve comprise that by an a pair of locomotive reversing plug normal open switch 5 and normally closed switch 6 control respectively, only make the stucco of locomotive forward direction; Main supply switch 7 is used for safeguarding or the maintenance electric control circuit is used; During online use, because the power supply voltage height does not wait, the first diode 8 is used for controlling the electric current one direction and passes through major loop by reverse electromagnetic valve coil 4, the three diodes 10 for control electric current one direction for control electric current one direction by forward electromagnetic valve coil 3, the second diodes 9;
2) control automatic stucco by pressure relay, when emergency braking, the pressure relay airduct fills wind, and circuit is connected in pressure relay 11 actions, and forward electromagnetic valve or reverse electromagnetic valve get electronic work, and the pressure air of total reservoir enters the sander stucco.
3) by the automatic stucco of microcomputer control signal circuit 12 controls, when the traction motor maximum current〉500A, the poor ratio with average current of maximum current〉20% the time, microcomputer control stucco simultaneously display fault Information shows that " idle running " is if can eliminate idle running by stucco, difference between current diminishes, and then automatically stops stucco.If idle running further increases, when ratio〉30% the time, microcomputer control continues stucco and the linear main generator horsepower output that reduces, and shows simultaneously " serious idle running ".After idle running was eliminated, microcomputer stopped stucco automatically, and recovered the original power of main generator.
There is following shortcoming in prior art:
1, still frequent stucco when locomotive does not have speed not only causes the wasting of resources and environmental pollution, and consists of potential safety hazard.The sand pad that self stucco causes during the unit emergency braking may be blocked track circuit; The sand pad that a plurality of locomotives cause in same local stucco for a long time can make the not conducting of track circuit of the locomotive that rested on afterwards on the sand pad, the crisis of formation accident equally.
2, only have foot-operated switch, the driver can only operate with pin, in case malfunctioning switch can't operate.
When 3, train starting draws, without automatically stucco, and after the idle running disappearance, nothing time-delay stucco function.Can't give full play to locomotive and start adhesive tractive effort.
4, in the section during servicing work emergency braking tests of locomotive brake gear be must Test item, this test causes unnecessary stucco.
Summary of the invention
The invention provides a kind of diesel locomotive stucco electrical controller, be used for overcoming defective of the prior art, realize saving sand grains, cut the waste and environmental pollution; Increase the locomotive adhesion; Strengthen traffic safety.
The invention provides a kind of diesel locomotive stucco electrical controller, this device comprises for according to train tube pressure and preset value comparative result and closed pressure relay, forward stucco electromagnetic valve, oppositely stucco electromagnetic valve and control circuit, this control circuit comprises two parallel branches that are connected between dc power anode and the negative pole, and one of them parallel branch comprises this pressure relay; Another parallel branch comprises the manual control circuit of series connection, stucco circuit and main supply switch, this device also comprises the speed sensor for detection of vehicle wheel rotational speed, pair of contact and slug relay that the vehicle wheel rotational speed that detects according to this speed sensor and preset rotation speed comparative result move, this comprises open contact and normally closed contact to the contact, described slug relay comprises time-delay coil and time-delay normally closed contact, described time-delay coil and open contact are all connected with described pressure relay, described normally closed contact is connected between described manual control circuit and the stucco circuit with circuit one end after described time-delay normally closed contact is in parallel, and the other end is connected between described pressure relay and the time-delay coil or is connected between pressure relay and the open contact.
Diesel locomotive stucco electrical controller of the present invention, when emergency braking condition, it is large that train tube pressure becomes, pressure relay is closed, electromagnetic valve gets electric, the beginning stucco, when the rotating speed that speed sensor detects wheel was lower than preset value, open contact was closed, and normally closed contact disconnects, the time-delay coil gets electric, the time-delay normally closed contact disconnects after through the time of setting, and controls the stucco amount by slug relay, can stucco when locomotive does not have speed, relative prior art economizes on resources, protection of the environment, avoids potential safety hazard; The sand pad blocking-up track circuit that self stucco can not cause during the unit emergency braking; A plurality of locomotives can not cause the sand pad equally can not make the not conducting of track circuit of the locomotive that rested on afterwards on the sand pad in same local stucco for a long time yet yet, avoid the crisis of formation accident.
