Description

Technical Field

[0001] This invention belongs to the field of railway safety monitoring technology, and specifically introduces a bracket structure that is compatible with magnetic head wiring and car number installation. Its main function is to realize car number fixing and magnetic head wiring. Background Technology

[0002] The Vehicle Operation Safety Monitoring System (5T System) serves the Chinese railway vehicle sector. It employs intelligent, networked, and information-based technologies, constructing 5T System detection stations along railway lines to achieve dynamic detection, centralized data collection, networked operation, remote monitoring, and information sharing of passenger and freight vehicle operation safety by ground equipment. By establishing a comprehensive, all-encompassing, and three-dimensional ground-to-vehicle safety monitoring system, it constructs a safety barrier for railway transportation, ensuring the safety of railway transportation.

[0003] The railway vehicle infrared axle temperature detection system (THDS) is part of the 5T system. It is responsible for non-contact detection of railway trains, detecting hot axles and preventing hot axle shearing, which plays an important role in the safe operation of railway vehicles. Existing THDS systems are installed along railway lines, such as the literature [1]: Chen Dong. Principle and application of intelligent axle temperature detection system [J]. Shanghai Railway Science and Technology, 2011(02), 23-24, which describes an unattended automated detection device composed of infrared detection probes, housing and control cabinet and other main components.

[0004] The miniaturized THDS system's trackside enclosure and car number are installed on custom-made sleepers. The sleepers have pre-reserved wiring channels; both the enclosure's cables and the car number's cables connect to equipment in the trackside cabinet or equipment room via these channels. The magnetic head is mounted on the rail using a rail-mounted method. Currently, the connection between the magnetic head cable and the control equipment involves drilling a hole in the probe enclosure. The magnetic head cable first enters the probe enclosure through this hole, and then, along with other cables inside the enclosure, connects to the control equipment in the trackside equipment room or cabinet via a laid steel conduit. Figure 1 As shown. However, this method has the following drawbacks: 1) The miniaturized THDS detector box is small in size and has limited internal space, making it difficult to accommodate the magnetic head cable and its connector; 2) The magnetic head cable needs to cross the rails to enter the detector box, which can easily damage the cable during the tamping process of the railway tamping machine, and does not meet the requirement of tamping without disassembly.

[0005] To address the problems existing in the prior art, a bracket structure compatible with magnetic head wiring and vehicle number mounting is provided, thus resolving the aforementioned issues.

[0006] This utility model is a bracket structure compatible with magnetic head wiring and car number installation. It includes a bracket, a cover plate, a threaded plate and a magnetic head wire inlet, and is installed as a whole in the middle of the THDS special sleeper.

[0008] The bracket has holes on its bottom surface that are fitted with screws to fix it to the middle of the THDS special sleeper; at the same time, the hollow part on the bottom surface of the bracket is connected to the hollow part on the top surface of the THDS special sleeper; and nuts are fixedly installed below each hole on the top surface of the bracket.

[0009] The magnetic head cable inlet is a cylindrical structure, and its ends are fixed to the through holes designed at the front and rear corresponding positions on the left end of the bracket.

[0010] The magnetic head cable enters the machine room sequentially through the inlet, the top cable routing port of the sleeper, and the steel braided tube connected to the THDS special sleeper; the protective rubber tube wrapped around the magnetic head cable is inserted into the inlet of the magnetic head cable and fixed with a clamp.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] This utility model relates to a bracket structure compatible with magnetic head wiring and vehicle number mounting, comprising a bracket 1, a cover plate 2, a threaded plate 3, and a magnetic head cable inlet 4. Figure 2 As shown.

[0026] like Figure 3 As shown, the bracket 1 is a hollow rectangular frame structure made of angle steel, with side walls in the circumferential direction. The bracket has a length of 720mm in the left-right direction, a width of 219mm in the front-back direction, and a height of 60mm in the longitudinal direction. The top left side of the bracket 1 has a beam 101 designed along the front-back direction. The bracket 1 section on the left side of the beam 101 has a length of 104mm in the left-right direction and is used to connect and accommodate the magnetic head cable; the bracket 1 on the right side of the beam 101 is used to fix the vehicle number 9 (automatic identification device and data processing unit in the vehicle number recognition system (AEI)) and the vehicle number cable connection.

[0027] The bottom edge of bracket 1 has three sleeper connection holes 102 at equal intervals from left to right. The bracket 1 is fixedly installed on the upper surface of the THDS special sleeper by bolts passing through each hole and engaging with the nuts embedded in the THDS special sleeper (a hollow sleeper with a pre-reserved channel for wiring and a cable inlet on the top surface).

[0028] The top surface of the bracket 1, which faces each of the aforementioned holes, is divided into a hollow section, so that it will not obstruct the holes from above and hinder the installation of bolts. Furthermore, after the bracket 1 is fixed on the THDS special sleeper, the hollow section on the bottom surface of the bracket 1 serves as the cable inlet, which communicates with the cable inlet on the top surface of the THDS special sleeper.

[0029] Meanwhile, a lower sealing ring 5 is provided circumferentially between the support 1 and the THDS special sleeper to prevent rainwater from entering the support through the gap between them. The lower sealing ring 5 is positioned on the annular protrusions designed on the bottom surface of the support 1 along the beam 101, the front edge of the bottom surface of the support 1, the right edge of the bottom surface of the support 1, and the rear edge of the bottom surface of the support 1.

[0030] The top beam 101 of the bracket 1 has two vehicle number mounting holes A103, one at the front and one at the rear. Two connecting nuts are welded and fixedly installed on the bottom surface of the beam 101, coaxial with the two vehicle number mounting holes A103. The right side of the top surface of the bracket 1 has an outwardly extending portion, forming a platform structure 8. This platform structure 8 has two vehicle number mounting holes B104, one at the front and one at the rear. The two vehicle number mounting holes B104 are strip-shaped holes designed along the left-right direction.

[0031] The aforementioned car number mounting holes A103 and B104 are used to mate with the four through holes at the four corners of car number 9, fixing car number 9 to the top surface of bracket 1 with bolts. During car number 9 installation, two bolts pass through the two through holes on the left side of car number 9 and the corresponding car number mounting hole A103, and are threaded into the two nuts under beam 101. The other two bolts pass through the two through holes on the right side of car number 9 and the two car number mounting holes B104, and are threaded into the two threaded holes on the threaded plate 3 located below platform structure 8; thus fixing car number 9 to the top surface of bracket 1, and simultaneously sealing the hollow portion of the top surface of bracket 1 located on the right side of beam 101. During the installation of car number 9 and bracket 1, an upper sealing ring 6 is provided between them, positioned on the annular protrusions designed along beam 101, the front edge of the top surface of bracket 1, the right edge of the top surface of bracket 1, and the rear edge of the top surface of bracket 1.

[0032] The strip-shaped hole design of the two car number mounting holes B104 mentioned above can accommodate the size error of car number 9 and the machining error of bracket 1 when installing car number 9. If the hole design of bracket 1 and car number 9 can ensure that the position of each connecting hole is strictly accurate and without error, then car number mounting holes B104 can also be designed as round holes, which can be opened at the right edge of the top surface of the frame 1, without the need for a platform structure design; at the same time, two connecting nuts are welded to the lower surface of the platform structure 9 on the right edge of the top surface of the frame, which are coaxial with the two car number mounting holes B104 respectively.

[0033] like Figure 4 , Figure 5 As shown, the aforementioned threaded plate 3 is an independent part. Its upper surface has a rectangular guide groove 301 designed perpendicular to the line connecting the two threaded holes. This guide groove 301 is used to engage with a rectangular protrusion 105 designed perpendicular to the line connecting the centers of the two vehicle number mounting holes B104 on the lower surface of the platform structure 8, achieving alignment between the two threaded holes on the threaded plate 3 and the two vehicle number mounting holes B104. Therefore, when installing the threaded plate 3, by sliding the threaded plate 3 in conjunction with the rectangular protrusion, the two threaded holes on the threaded plate 3 can reach the positions of the two vehicle number mounting holes B104 on the platform structure 8 during the sliding process.

[0034] The cover plate 2 is fixedly installed on the left side of the top surface of the bracket 1 to seal the hollow part on the left side of the top beam of the bracket 1. The cover plate 2 has through holes on both its front and rear sides, which respectively mate with the through holes designed at the front and rear edges of the left side of the top surface of the bracket 1. Simultaneously, two connecting nuts, coaxial with their upper through holes, are welded and fixedly installed on the lower surface of the front and rear edges of the left side of the top surface of the bracket 1. Then, bolts are passed through the through holes corresponding to the top surface of the cover plate 2 and the bracket 1 to connect with the connecting nuts, thus fixing the cover plate 2. A cover plate sealing ring 7 is provided between the cover plate 2 and the left side of the top surface of the bracket to achieve a seal; the cover plate sealing ring 7 is fitted onto the annular protrusion designed on the left side of the top surface of the bracket 1 along the rear edge of the top surface of the bracket 1, the left side edge of the top surface of the bracket 1, the front edge of the top surface of the bracket 1, and the beam 101.

[0035] The magnetic head cable inlets 4 are two hollow cylindrical structures, with their ends welded and fixed to corresponding through holes on the left end of the bracket 1. The two magnetic head cable inlets 4 are angled upwards, with their axes forming a 15° angle with the horizontal plane to facilitate the connection of the rubber tube. The front ends of the two magnetic head cable inlets 4 have circumferentially raised protrusions designed to engage with the clamps that lock the rubber tube, preventing the clamps from falling off.

[0036] In application, the bracket structure of this utility model, which is compatible with magnetic head wiring and vehicle number installation, first fixes bracket 1 to the top surface of the THDS-specific sleeper, located between the two probe boxes. For example... Figure 6 As shown, the magnetic head cable enters the bracket 1 through the magnetic head cable inlet 4. Simultaneously, the protective rubber tube encasing the magnetic head cable is inserted into the magnetic head cable inlet 4 and secured with clamps. After entering the bracket 1, the magnetic head cable runs through the interior of the bracket 1, entering the THDS-specific sleeper through the cable routing port on the top of the sleeper, and then entering the machine room through the steel braided tube connected to the THDS-specific sleeper. This ensures that the magnetic head cable does not cross the rails during its routing, preventing damage to the magnetic head cable during the railway tamping process. Furthermore, the magnetic head cable no longer needs to enter the THDS detection box; it can directly enter the machine room, saving space inside the probe box.
