Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation, in particular to an emergency self-stabilizing infrared shaft temperature detection system to avoid brittleness and fragmentation. Background Art

[0002] The infrared axle temperature detection device is a safety protection facility that performs non-contact detection on rail trains to detect hot axles of vehicles and prevent hot axles. It is an important equipment to ensure the safety of railway transportation. The infrared axle temperature detection device applies advanced technologies such as optics, infrared remote sensing, information processing, communication networking and automatic control. When the vehicle passes through the detection station, the device uses the infrared detector in the infrared probe installed on the trackside to detect the size of the infrared radiation emitted by each vehicle bearing and converts it into a corresponding voltage signal. The higher the temperature of the bearing surface, the higher the energy of its infrared radiation, and the higher the corresponding voltage value output by the infrared probe, thereby achieving the purpose of vehicle axle temperature detection and detecting hot axles.

[0003] The existing patent (Announcement No.: CN201124845Y) is a shaft temperature detection device, including a box, a detection window, a shaft temperature probe, and a probe adjustment mechanism. The probe adjustment mechanism includes: a probe bracket, an arc-shaped convex part fixedly connected to the probe bracket; a guide rail bracket, an arc-shaped concave part fixedly connected. The two ends of the guide rail bracket are supported and fixed by two cross beams located in front and behind the shaft temperature probe. The outer convex surface of the arc-shaped convex part contacts the inner concave surface of the arc-shaped concave part. The two contact surfaces are part of the same sphere, and the center of the sphere coincides with the center point of the detection window. The convex part has an arc-shaped longitudinal groove, and the concave part has an arc-shaped longitudinal guide rail that cooperates with the arc-shaped longitudinal groove.

[0004] The existing technology has the following problems: the passing of a train will cause severe vibrations, which can easily damage the axle temperature detection components. The existing axle temperature detection components are more likely to become brittle under long-term exposure to the sun. When the train is running, the brittle nature of the components is more likely to be broken after continuous vibration, which shortens the maintenance cycle of the axle temperature detection components and requires frequent monitoring. There is a lack of relevant measures that can uniformly solve the chain problem of excessive brittleness and breakage due to vibration after exposure. Summary of the invention

[0005] The purpose of the utility model is to provide an emergency self-stabilizing infrared axle temperature detection system that avoids brittleness and fragmentation.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] As mentioned in the background technology of the present application, it has been found through research that the existing earthquake-resistant measures for the shaft temperature detection components are not perfect, resulting in a short maintenance cycle of the shaft temperature detection components and certain defects.

[0031] In order to solve the above-mentioned defects, the present application discloses an emergency self-stabilizing infrared axle temperature detection system that avoids brittleness and fragmentation. By setting up an anti-seismic assembly that avoids brittleness and fragmentation, the detection box 2 can be restrained and fixed when a train passes by, thereby improving the seismic performance of the detection box 2, avoiding damage to the detection box 2, and extending the maintenance cycle.

[0032] The following will describe in detail how the solution of the present application solves the above technical problems in conjunction with the accompanying drawings.

[0033] See also Figures 1 to 7 In the embodiment of the utility model, an emergency self-stabilizing infrared axle temperature detection system for avoiding brittleness and fragmentation includes: a rail 1, and an axle temperature detection assembly symmetrically fixed on both sides of the rail 1, wherein the axle temperature detection assembly includes a detection box 2 and an anti-brittleness and fragmentation anti-seismic assembly fixed on both sides of the detection box 2. By setting the anti-brittleness and fragmentation anti-seismic assembly, the detection box 2 can be constrained and fixed when a train passes by, thereby improving the anti-seismic performance of the detection box 2, avoiding damage to the detection box 2, and extending the maintenance cycle.

[0034] In this embodiment, the anti-fragile and anti-seismic assembly specifically includes: a base 3 symmetrically fixed on both sides of the detection box 2, a driving groove 7 is opened inside the base 3, and two parallel electric push rods 8 are embedded in the bottom end surface of the driving groove 7, the top output shafts of the two electric push rods 8 are commonly fixedly connected with a trapezoidal plate 9, and the top surface of the trapezoidal plate 9 is fixedly connected with three evenly distributed optical axes 10 along its length direction, the optical axes 10 on the two trapezoidal plates 9 pass through the corresponding base 3 and are commonly fixedly connected with a sunshade 6, and each trapezoidal plate 9 is provided with a synchronous clamp on the side close to the detection box 2. The setting of the anti-fragile and anti-seismic assembly can constrain and fix the top and both sides of the detection box 2 when necessary, thereby improving the anti-seismic performance of the detection box 2.

[0035] In this embodiment, the synchronous clamping piece specifically includes: a shaft 18 fixed inside the driving groove 7, the outer side of the shaft 18 is rotatably connected to three parallel right-angle plates 11 along its length direction, and one end of the right-angle plate 11 is fixedly connected to a clamping plate 12, and one side of the clamping plate 12 is fixedly connected to a rubber gasket 19, which can not only prevent the clamping plate 12 from crushing the detection box 2, but also improve the seismic performance of the detection box 2. The synchronous clamping piece can clamp the side of the detection box 2 and automatically return to the initial position after the train leaves, which is convenient for use.

[0036] In this embodiment, a strip reinforcement plate 4 is fixedly connected to the bottom end of the side of the base 3 away from the detection box 2, and a vibration sensor 5 is embedded in the side of the strip reinforcement plate 4 facing the rail 1. The vibration sensor 5 can sense the vibration of the rail 1 when the train passes by, and send the collected information to the background control terminal, which timely controls the operation of the anti-fragmentation and anti-seismic assembly to constrain and fix the detection box 2.

[0037] In this embodiment, the bottom end surface of the sun visor 6 is fixedly connected with a plurality of evenly distributed anti-vibration cotton blocks 13 along its length direction. The sun visor 6 can not only provide sunshade effect, but also constrain the top of the detection box 2 when needed, while the anti-vibration cotton blocks 13 can prevent the detection box 2 from being crushed and improve the anti-vibration performance of the detection box 2.

[0038] In this embodiment, an aluminum alloy rectangular sleeve 15 is provided inside the detection box 2, and three parallel aluminum alloy circular sleeves 17 are fixedly connected to the top of the aluminum alloy rectangular sleeve 15. The aluminum alloy circular sleeves 17 are connected to the aluminum alloy rectangular sleeve 15, and the top of the aluminum alloy circular sleeve 17 penetrates the top surface of the detection box 2. When the train passes by, the air flow near the rail 1 is fast, and the heat inside the detection box 2 can be quickly discharged through the aluminum alloy rectangular sleeve 15 and the aluminum alloy circular sleeve 17, thereby improving the heat dissipation performance of the detection box 2.

[0039] In this embodiment, the openings at both ends of the aluminum alloy rectangular sleeve 15 are fixedly connected with filter screens 16. The filter screens 16 can reduce the impurities in the outside air from entering the interior of the aluminum alloy rectangular sleeve 15.

[0040] In this embodiment, two parallel axle temperature probes 14 are embedded above one side of the detection box 2 facing the rail 1. The axle temperature probes 14 are used to monitor axle temperature information, and the axle temperature probes 14 are selected from the axle temperature probes 14 disclosed in the background art.

[0041] The working principle of the utility model is:

[0042] The utility model can realize the self-protection process of its own complete performance in the environment of excessive exposure to sunlight and periodic vibration for a long time, ensure the basic use performance of the shaft temperature detection component is complete and durable, reduce the frequency of inspection and maintenance, avoid frequent operation of replacing parts, and reduce maintenance costs.

[0043] There are two working modes of the anti-fragmentation and anti-seismic assembly. In the first working mode, the sunshade 6 is raised and the clamping plate 12 is located in the driving groove 7;

[0044] Combination Figure 2 As shown; in the second working mode, the sunshade 6 is lowered and pressed on the top of the detection box 2, and the clamping plate 12 is located outside the driving groove 7 and abuts against the side of the detection box 2;

[0045] Combination Figure 3As shown. When the train has not yet reached the infrared axle temperature detection device, the anti-fragmentation and anti-seismic assembly is in the first working mode. In this state, the two sides and the top of the detection box 2 are not blocked and can be in contact with the air over a large area, which accelerates the heat dissipation speed. When the train is about to reach the infrared axle temperature detection device, the vibration sensor 5 collects the vibration signal of the rail 1 and sends the collected vibration signal to the background control terminal. The background control terminal promptly controls the operation of the anti-fragmentation and anti-seismic assembly to constrain and fix the detection box 2 to ensure that the anti-fragmentation and anti-seismic assembly switches from the first working mode to the second working mode, specifically: the electric push rod 8 runs to retract the output shaft, the sunshade 6 is lowered and pressed on the top of the detection box 2, and the trapezoidal plate 9 follows the downward pressure and rotates around the shaft 18 against the right-angle plate 11, and the clamping plate 12 on the right-angle plate 11 is rotated out of the drive slot 7 and against the side of the detection box 2, thereby constraining and fixing the top and both sides of the detection box 2 at the same time, improving the anti-seismic performance of the detection box 2. In addition, when the train is passing, the air near the rail 1 flows quickly, and the aluminum alloy rectangular sleeve 15 and the aluminum alloy circular sleeve 17 can absorb the heat inside the detection box 2, and then dissipate the heat into the airflow and quickly discharge it during the rapid flow of air, thereby improving the heat dissipation performance of the detection box 2. When the train is far away, the anti-fragmentation and anti-seismic assembly switches from the second working mode to the first working mode, the electric push rod 8 runs and extends the output shaft, the sun visor 6 rises, and the right-angle plate 11 returns to the initial position under the gravity of the clamping plate 12. In this embodiment, the model of the vibration sensor 5 is Z3TD, and the model of the electric push rod 8 is NKLA64.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
