Description
Technical field
The present invention relates to a kind of railway security working truck, especially relating to a kind of railway ballast cleaning car being applied to railway engineering field transfinites construction operation sacurity alarm system.
Background technology
Railway ballast cleaning car (hereinafter referred to as cleaning car) is used to the Work machine of railway ballast in ballast cleaning, dirty railway ballast digs out from the pillow end by it, after sieving, more clean railway ballast is backfilled to railway roadbed, and by the dirty native feedway of revolution, the dirt soil sifted out is scavenged into outside circuit.In the prior art, the structural representation of RM80 type tunneling boring ballast screening machine is disclosed in master thesis " research of the RM80 type tunneling boring ballast screening machine mining ability deficiency problem " literary composition delivered on March 1st, 2003 by Southwest Jiaotong University horse good citizen.Turning round dirty native feedway is arranged on above machine front vehicle frame, and the corner size of swing type mechanism depends on hydraulic cylinder piston stroke, and the hard-over of RM80 screen scarifier is ± 70 °.Revolution dirty dust conveyer belt, when operation, is 4800mm relative to the maximum height of rail level, and maximum throwing soil distance is 5500mm with the distance of track centerline.According to railway construction clearance regulation, the distance of contact system electric pole and wire center is about 3500mm, is in outside contact system electric pole, may encounters contact system electric pole, there is larger potential safety hazard when therefore turning round dirty native feedway work.
In current domestic cleaning car practice of construction secure administration procedure, what mainly adopt is that operating personal manual observation ensures construction safety.When the operation of cleaning car, the naked eyes by means of only driver judge and the warning of Security Officer judges the opportunity of regaining dirty native feedway.But in the construction operation process of reality, because camp site is a riot of sound, Security Officer and driver's confusing communication, and the carelessness of driver and speed of response cross the reasons such as slow, all can cause and can not reclaim load-transfer device in time, so that knock the grave accident of contact system electric pole over.Therefore existing cleaning car Safety Management will cause construction operation personnel on the one hand to increase, and maintenance cost increases, and on the other hand, manual observation relies on sensitieness and the sense of responsibility of personnel, and when maintenance task is heavy, the easy burnout carelessness of personnel, very easily causes accident.
In the middle of prior art, applied on October 27th, 2009 by railway line for passenger traffic Infrastructure maintenance center, Wuhan Railway office Wuhan, Wuhan University of Technology, and on 08 11st, 2010 bulletins, notification number was that the Chinese utility model patent of CN201545000U discloses one " anti-collision alarming device for track screen cleaning vehicle ".In this utility model patent, propose a kind of device using super sonic to carry out keeping away barrier, it comprises Programmable Logic Controller, ultrasonic transduter and warning device; Programmable Logic Controller, warning device are arranged on track screen cleaning vehicle, the dirt soil that ultrasonic transduter is arranged on track screen cleaning vehicle gets rid of arm front end, the mouth of ultrasonic transduter is connected with the signal input part of Programmable Logic Controller, and warning device is by Controlled by Programmable Controller.This utility model anti-collision alarming device for track screen cleaning vehicle is a kind of active defense mode, gets rid of arm collision-proof warning device based on the dirty soil of cleaning car of ultrasonic technology, can get rid of arm distance preceding object thing a distance at dirty soil and send alerting signal, alert gets around obstacle.But this device hardware is complicated, only on dirty dust conveyer belt with regard to mounting ultrasonic sensor, stepping motor, the components and parts such as Drive Module and proximity switch, and cleaning car construction operation bad environments, dirty dust conveyer belt vibration is large, and dust coverage condition is serious.On the one hand, easily cause ultrasonic transduter pedestal unstable, calculate distance in real time and there is larger error; On the other hand, dust dregs easily causes proximity switch work unreliable, the work that system can not be reliable and stable.

Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in accompanying drawing 1 to accompanying drawing 11, give the specific embodiment that a kind of railway ballast cleaning of the present invention car transfinites construction operation sacurity alarm system and the construction operation safety alarm method that transfinites based on the railway ballast cleaning car of this system, below in conjunction with the drawings and specific embodiments, the invention will be further described.
The specific embodiment of the invention provides the railway ballast cleaning car construction operation sacurity alarm system that transfinites can realize obstacle 3, as the spacing between contact system electric pole detects and closely alarm, cleaning car 1 carries out alarm in the distance of setting, in emergency circumstances, the dirty native feedway 2 of revolution can be triggered stop swinging, or cleaning car 1 stops operation walking, guarantee construction safety.
That a kind of railway ballast cleaning of the present invention car transfinites the detailed description of the invention of construction operation sacurity alarm system as shown in accompanying drawing 1 to 5, as shown in Figure 1 for railway ballast cleaning car provided by the invention transfinites the structural representation of a kind of detailed description of the invention of construction operation sacurity alarm system.
The specific embodiment of the invention takes the scheme that detection is measured and construction safety alarm two step that transfinites is walked:
(a) high speed detection process: as shown in Figure 2, detection of obstacles module 12 detects the spacing distance of obstacle 3 fast, distance measurement sensor 13 obtains cleaning car and travels mileage information, formed and comprise obstacle information and the mileage contrast information that obstacle 3 arrives orbit centre distance, shown by human-computer interaction module 14, and add according to result of a measurement or delete the information of obstacle 3;
