Description
Technical field
The utility model relates to railway locomotive control technology field, relates in particular to a kind of railway locomotive absorption type temperature sensor.
Background technology
The bearing temperature alarm of railway locomotive has crucial effects for the security of operation of locomotive, and existing bearing temperature alarm mainly contains dual mode:
1, built-in type sensor type of alarm:
Directly sensor is imbedded pre-buried hole measurement temperature on the bearing, all to adorn the bearing temperature alarm device be exactly this type to all passenger vehicles at present, and product design is simple, directly measures the reliability height.This programme advantage is directly to measure axle temperature, and shortcoming is to slot on axle box or to punch.But, some locomotive, such as harmonious locomotive, its bearing and axle box do not allow to slot on existing locomotive because of the reason of material and design, and traditional axle temperature checkout equipment is installed.
2, infrared sensor type of alarm:
Any object is because the motion of himself molecule, outside radiated infrared heat energy ceaselessly, thus form certain temperature field at body surface, be commonly called as " thermal imagery ".Infrared thermometer detects by absorbing the infrared radiation energy that object sends, and measures the temperature of equipment surface and the distribution in temperature field, thereby the Temperature Distribution situation on accurate judgment object surface has advantages such as accurate, real-time, quick.But, running environment very severe often at the bottom of the locomotive car, infrared sensor thermometric accuracy to camera lens cleaning have relatively high expectations, pollutions such as dust greasy dirt will cause thermometric inaccurate even deviation is bigger, need often safeguard camera lens.Therefore, this scheme advantage is a contact measurement not, does not destroy car body axle box structure; Shortcoming is often to safeguard clean lens, and the cost cost is higher.
The utility model content
The purpose of this utility model is to design a kind of novel railway locomotive absorption type temperature sensor, overcomes above-mentioned shortcoming of the prior art, addresses the above problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of railway locomotive absorption type temperature sensor, comprise sensor outer housing, directed magnet, sensor, lead and sensor circuit, described sensor circuit is arranged on the sensor circuit board, described sensor outer housing comprises housing and the loam cake that matches with described housing, described housing comprises shell base plate, sidewall, lead fairlead and circuit board erecting bed, have circuit board mounting hole and sensor fixed orifice on the described circuit board erecting bed, form magnet-fixation grooves between described shell base plate, described circuit board erecting bed and the described sidewall; Described directed magnet is arranged in the described magnet-fixation grooves, described sensor is arranged in the described sensor fixed orifice, described sensor circuit board is positioned on the described circuit board erecting bed and is fixed on the described sensor fixed orifice, and described lead is introduced and is connected on the sensor circuit board by described lead fairlead.
Be filled with heat-conducting silicone grease in the described sensor fixed orifice.
Space between described housing and the described loam cake keeps sealing all by the encapsulant embedding.
Space between described housing and the described loam cake is all by the epoxy resin embedding.
Described lead fairlead place is arranged with heat-shrink tube.
The lateral surface of described shell base plate is for installing surface of contact, and described installation surface of contact is plane or curved surface.
Described directed magnet is high-strength directional magnet.
Described circuit board mounting hole has two, and described sensor fixed hole position is between two described circuit board mounting holes.
The utility model absorption type sensor is monitored the rapid temperature rise of its fault omen by being adsorbed on the locomotive running gear position, and device in time sends acousto-optic and the audio alert signal is taked corresponding measure to remind the driver, the generation of prevention major accident.The problem that this programme emphasis solves is the bearing of harmonious locomotive etc. and the axle box reason because of material and design, do not allow on existing locomotive, to slot, can not destroy the axle box structure, the sensor of traditional axle temperature checkout equipment can not be installed, this absorption type sensor can address this problem.
This sensor is easy for installation succinct, now installs in the HXD1 of east of a lake locomotive depot, the electric locomotive of HXD2 type and comes into operation.Concrete installation method:
Sensor is installed 6 at every of the electric locomotive of HXD type, comprises 2 on left and right sides axle box, 2 of left and right sides axle suspension bearings, 2 of left and right sides motor bearings.HXD1, HXD2 are that 8 locomotives need be installed 48 sensors; HXD3, HXD1B, HXD2B, HXD3B are six locomotives, need to install 36 sensors.On each mounting points, carry out scrubbing work earlier, use the sand papering surface of contact then, make surface of contact totally level and smooth, on surface of contact, evenly smear electric heating silica gel, according to the type of the surface of contact sensor that described installation surface of contact is installed is curved surface or plane.This sensor has ferromagnetism, so can be stable be fixed on body surface with ferrous metal character, fixing more firm or will be installed in and do not have a body surface of iron ferrous metal character for making, should beat fixing glue fixes sensor all around with the object surface of contact at sensor.
The beneficial effects of the utility model are as follows:
(1) the utility model can be realized the not contact measurement of locomotive axle temperature, does not destroy car body axle box structure.
(2) the utility model can be realized do not slot accurate measurement under the prerequisite of axle box, no potential safety hazard, installation, use, easy to maintenance.
(3) the utility model to the locomotive car at the bottom of the adaptive faculty of running environment strong, cheap for manufacturing cost, maintenance cost is low.
