Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The action synoptic diagram of the unit brake device for detecting distance of travel that the synoptic diagram of the unit brake device for detecting distance of travel that Fig. 1 provides for the utility model, Fig. 2 provide for the utility model.As shown in Figure 1 and Figure 2, unit brake comprises pedestal 5, is fixed on the checking cylinder that has piston rod 64, lever kinematic train, brake pushrod 10 and brake shoe 7 on the pedestal 5, one end of the lever 3 in the lever kinematic train is connected on the piston rod 6 of checking cylinder 4, the other end is connected an end of brake pushrod 10, and the other end of brake pushrod 10 is connected on the brake shoe 7.The unit brake device for detecting distance of travel of this embodiment comprises signal gathering unit 1 and detecting signal unit 2, wherein to be used to gather the brake cylinder piston rod 6 that links to each other with checking cylinder 4 be the stroke signal of piston pulling rod to signal gathering unit 1, then this signal is sent to detecting signal unit 2, the stroke signal of the piston rod 6 that detecting signal unit 2 received signal collecting units 1 send, and the stroke signal of piston rod 6 is scaled the run-length data of brake shoe 7, thereby draw critical distance between brake shoe 7 and the wheel tread 8 whether within safe range according to lever 3 enlargement ratios of lever kinematic train.
The signal gathering unit 1 of this embodiment can comprise signal generator 11 and signal receiver 12.Signal generator 11 can be a magnetic module, and signal receiver 12 can be hall sensor, and signal generator 11 is arranged on the piston rod 6 of checking cylinder of unit brake.Preferably, on the connecting pin 9 of the lever 3 in signal generator 11 piston rod 6 that is installed in checking cylinder and the lever kinematic train.Interaction by gaseous tension in the checking cylinder 4 and spring 41, signal generator 11 is along with brake cylinder piston rod 6 moves together, the distance between brake shoe 7 and the wheel tread 8 is delivered to brake cylinder piston rod 6 by brake pushrod 10 and via 3 amplifications of the lever in the lever kinematic train.There is proportionate relationship in brake cylinder piston rod 6 on the checking cylinder 4, for example 3.2 times with the stroke of brake shoe 7.When the critical distance of brake shoe 7 and wheel tread 8 be stroke when safe range is for example between the 7-12mm, to be that stroke is corresponding be 22.4-38.4mm to the critical distance of the brake cylinder piston rod 6 that signal gathering unit 1 is gathered.Therefore signal receiver 12 Initial fixs that are arranged on unit brake pedestal 5 inboards are selected in the 22.4mm place, as brake shoe 7 and wheel tread 8 minimum spacing signal sampling points 121, at the 38.4mm place as brake shoe 7 and wheel tread 8 maximum spacing signal sampling points 122.Wherein, a plurality of signal receivers 12 can also be set as required, in order to carry out the warning of multiple level of security.Signal receiver 12 collects the stroke signal of signal generator 11, can be sent to detecting signal unit 2 by the shielded multiconductor cable line.
Detecting signal unit 2 comprises signal processing unit 21 and alarm unit 22.When signal processing unit 21 draws stroke between brake shoe 7 and the wheel tread 8 and exceeds preset threshold value according to the stroke signal that receives, send alarm command to alarm unit 22, so that alarm unit 22 sends corresponding warning message.When the run-length data of brake shoe 7 exceed predetermined threshold value on send in limited time and exceed upper limit alarm information; Following the sending in limited time that exceeds predetermined threshold value when the run-length data of described brake shoe 7 exceeds the lower limit warning message.Alarm unit 22 can be audio alarm unit and/or video alarm unit.
With 8 pairs of wheel locomotives is example, and each wheel is provided with a unit brake, and each unit brake all is provided with a corresponding signal gathering unit 1, and therefore 16 signal gathering unit 1 are set altogether.Each unit brake adopts quick aviation connector to be connected in the junction box, is separately fixed on the trailing or leading bogie.Adopt bus mode to connect detecting signal unit 2, each bogie is half of a bus unit.Preceding 4 to take turns be a bus unit, and another bus unit is taken turns in back 4, by the unit connection box, adopt quick aviation connector with data delivery to detecting signal unit 2.Transmission line adopt corrugated stainless steel tubing do in conductive pipe, external application stainless steel webmaster go bail for protect heat insulation.The terminal box pipe-line all is fixed on the engine truck.Two buses that the front and back four-wheel is two groups are prolonged the locomotive trough and are connected with detecting signal unit 2.Correspondingly, detecting signal unit 2 is provided with 16 alarm units 22, and alarm unit 22 can be video alarm unit and/or audio alarm unit.The video alarm unit can adopt the LED lamp.Each signal gathering unit 1 corresponding two LED lamp surpasses upper threshold to the distance between brake shoe 7 and the wheel tread 8 respectively and the threshold value lower limit is reported to the police, and color is obviously distinguished; The audio alarm unit is also can be at the distance between brake shoe 7 and the wheel tread 8 excessive and too smallly report to the police respectively, and obviously different.
The safe range of the critical distance between brake shoe 7 and the wheel tread 8 is 7-12mm, and scope is very for a short time to be unfavorable for direct measurement.The utility model can amplify measurement range with brake shoe 7 stroke proportionate relationships by brake cylinder piston rod 6 on the braking checking cylinder 4, for example 3.2 times, when the safe distance of brake shoe 7 and wheel tread 8 is 7-12mm, the safe distance of the signal gathering unit 1 corresponding brake cylinder piston rod of gathering 6 is 22.4-38.4mm accordingly, can improve the sensitivity of measurement like this.
By unit brake device for detecting distance of travel of the present utility model, can brake shoe quick and easy and judging unit detent accurately and the distance between the wheel tread whether within the scope of safety, when exceeding safe range, can send warning message, be convenient to the staff and adjust, safe and reliable.
