The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of electric-controlled type railway vehicle brake cylinder condition checkout gear, comprise detector body 1 and contact lever 2, described detector body 1 rear end is provided with detector lid 3, described detector body 1 rear end and detector cover 3 junctions and are provided with O RunddichtringO 9, described contact lever 2 rear portions place detector body 1 internal cavity, detector body 1 is stretched out in its front portion, be provided with Bringing-back mechanism in described contact lever 2 front portions, described Bringing-back mechanism comprises the retracing spring 7 that is socketed on the contact lever 2 and the back-up ring 8 that is arranged on contact lever 2 front portions, described detector body 1 front end inside is stepped hole, described retracing spring 7 one ends are resisted against described stepped hole place, and its other end is resisted against on the back-up ring 8.
Wherein, be respectively arranged with micro-switch 4 in described detector body 1 internal cavity rear and front end, described micro-switch 4 is connected with signal wire (SW) 6 by Signal connector 5, described contact lever 2 rear portions can contact with the micro-switch 4 of detector body 1 internal cavity rear and front end respectively when mobile detector body 1 is interior, namely when the car brakeing cylinder is braked, described contact lever 2 rear portions contact with the micro-switch 4 of detector body 1 internal cavity front end, and described retracing spring 7 in the raw; When the car brakeing cylinder was alleviated, described contact lever 2 rear portions contacted with the micro-switch 4 of detector body 1 internal cavity rear end, and described retracing spring 7 is in compressive state.The stroke of detector is S=L1-L2, and wherein the L1 value is the piston travel maxim, and the L2 value is stretched out minimum value for brake cylinder piston rod, and the stroke of detector and the position of micro-switch can be set according to different model and the safety requirements of brake cylinder.
As shown in Figure 2, when the present invention used, the front end of described detector body 1 was threaded with the detector mount pad 11 that the piston rod of brake cylinder 10 links together, and described contact lever 2 front ends are resisted against on the baffle plate 12 of brake cylinder 10.
As shown in Figure 3, when car brakeing, detecting device is away from baffle plate, contact lever resets under action of reset spring, the micro-switch of contact lever compressed detected body Inner Front End, the micro-switch no signal output of the interior rear end of detector body this moment, the micro-switch of detector body Inner Front End has signal output, the braking of expression brake cylinder and brake cylinder piston rod stretch out fully, and retracing spring in the raw at this moment.
When brake cylinder was alleviated, brake cylinder piston rod drove contact lever near baffle plate, the retracing spring compression in the detecting device.
If the contact lever of detecting device is the micro-switch of compressed detected body Inner Front End still, the micro-switch no signal output of the interior rear end of detector body this moment, the micro-switch of detector body Inner Front End has signal output, and the expression brake cylinder does not have to have pressure between alleviation and brake shoe and wheel.
Do not arrive the micro-switch position of rear end in the detector body if the contact lever of detecting device is compressed by baffle plate, the equal no signals output of two switches this moment, the detecting device state as shown in Figure 4, the expression brake cylinder have improper release but between wheel and brake shoe without pressure.
If the contact lever of detecting device is compressed to the micro-switch position of rear end in the detector body by baffle plate, the micro-switch of the interior rear end of detector body this moment has signal output, the micro-switch no signal output of detector body Inner Front End, detector state as shown in Figure 1, the expression brake cylinder alleviate normal and the piston rod extension elongation in the specified value scope.
Wherein, the micro-switch signal is delivered to driver's control cabin through six pin signal wire (SW)s, by the detection to three kinds of states, the driver can understand the situation that brake cylinder relieved state and piston rod stretch out, and according to the difference notice station inspector of detected state vehicle is carried out respective handling.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
