Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in figure 1, the wireless temperature measuring device for the bearing outer ring of the railway wagon comprises an elastic support 1 fixed at the bottom of a wagon wheel bearing iron-stop bolt, a heat conductor 2 is installed on the elastic support 1, the heat conductor 2 is in contact with the wagon wheel bearing, a temperature sensor 3 used for detecting the temperature of the heat conductor is further installed on the elastic support 1, and the temperature sensor 3 is in wireless communication with a railway wagon control system.
The utility model discloses an elastic support 1 installation heat conductor 2 utilizes elastic support's elasticity to press the heat conductor on freight train wheel bearing's outer lane, and temperature sensor 3 detects the temperature of heat conductor. When the freight car wheel bearing breaks down, the bearing can produce high temperature, and on temperature transfer heat conductor 2, temperature sensor 3 detected high temperature, sent the railway freight car control system with temperature signal and reported to the police. The heat conductor 2 is made of copper, and the top of the heat conductor is provided with an arc surface which is in contact with the outer ring of the truck wheel bearing, so that the contact area of the heat conductor 2 and the truck wheel bearing can be increased, and the heat transfer efficiency is improved. Meanwhile, the temperature sensor is not directly contacted with the bearing of the wagon wheel, so that the temperature sensor can be effectively prevented from being damaged.
As shown in fig. 2, a fixing hole 4 is formed at the front end of the elastic support 1, the temperature sensor 3 is installed in the fixing hole 4 and fixed by a nut 5, a heat insulation groove 6 is fixed on the elastic support 1, a through hole 7 is formed at the bottom of the heat insulation groove 6, the heat conductor 2 is fixed in the heat insulation groove 6, and the top of the temperature sensor 3 passes through the through hole 7 and contacts with the heat conductor 2. The heat insulation groove 6 is of a groove-shaped structure made of rock wool or asbestos, the heat insulation groove is glued on the elastic support, the heat conductor is fixed in the heat insulation groove, the temperature of the heat conductor can be prevented from being transmitted outwards, and therefore the temperature sensor can be more accurate when detecting the temperature of the heat conductor.
The foregoing is considered as illustrative and not restrictive of the preferred embodiments of the invention, and any modifications, equivalents and improvements made within the spirit and principles of the invention are intended to be included within the scope of the invention.
