Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thereby a kind of design science is provided, installs firmly, the railway track temperature pick up of good heat-transfer, long service life.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of railway track temperature pick up, comprise sensor lower house, sensor upper shell and be located at the temp probe in the accommodating cavity of described sensor lower house, on described sensor lower house, wear screw rod, on the screw rod of described sensor lower house both sides, slide respectively and wear rail clamping termination, the upper inner of each described rail clamping termination have at the bottom of clamping Rail and with the draw-in groove that coincide and coordinate at the bottom of Rail, on the described screw rod in outside, described rail clamping termination, all revolve and establish clamp nut.
Base the above, between clamp nut and rail clamping termination, be provided with elastomeric pad.
Base the above, described sensor upper shell is aluminium alloys sensor upper shell, described sensor lower house is aluminium alloys sensor lower house.
Base the above, on the described screw rod of described sensor lower house both sides, all revolve and establish adjusting nut.
Base the above, described temp probe comprises round pie Stainless Steel Shell and is encapsulated in the 18b20 digital temperature chip in this Stainless Steel Shell by Heat Conduction Material.
Base the above, described accommodating cavity is and described temp probe the coincide round pie cavity that coordinates.
Base the above, described sensor lower house is provided with and is communicated with the cable-through hole of described round pie cavity, described cable-through hole outside is provided with buttock line locking head.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, the utility model by described sensor lower house and described sensor upper shell by sensor package in accommodating cavity, on described sensor lower house, wear screw rod, on the screw rod of sensor lower house both sides, wear rail clamping termination, at the bottom of the upper inner of this rail clamping termination has clamping Rail and with the draw-in groove that coincide and coordinate at the bottom of Rail, in use, by this railway track temperature pick up as for below rail, press close to the bottom surface at the bottom of Rail, afterwards rail is clamped on termination is stuck at the bottom of Rail by draw-in groove, by locking member, two rail clamping terminations are locked again, make entirety solid and reliable, draw-in groove and identical cooperation at the bottom of rails, the shape that draw-in groove is more fitted at the bottom of Rail, clamping is more steady, particularly prevent that this sensor from rotating.
Further, the upper and lower casing of sensor is made with aluminum alloy material, good heat conductivity, intensity is high, and can resist corrosion and the shock of the environmental factor such as rainwater, greasy dirt, road Cha of rail environment of living in, long service life arranges elastomeric pad between clamp nut and rail clamping termination, make fastening better effects if, reduce the generation of vibrations.
Further, the encapsulation probe of sensor is included as the thin Stainless Steel Shell of round pie, is provided with the round pie cavity corresponding with it in sensor lower house, makes the contact surface of sensor probe and housing large, is more beneficial to the transmission of heat.
It has advantages of design science, install firmly, good heat-transfer, long service life.
