Description

Technical Field

[0001] The utility model relates to the technical field of rail transit positioning equipment, in particular to a high-precision positioning device for a rail vehicle. Background Art

[0002] Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. The most typical rail transit is a railway system consisting of traditional trains and standard railways. However, with the continuous development of train and railway technology, rail transit has shown more and more types, not only used for long-distance land transportation, but also widely used in medium and short-distance urban public transportation. With the development of rail transit and the improvement of the intelligence of the rail transportation network, more and more rail vehicles are now equipped with locators, which can track and feedback the position of each rail vehicle in real time. The RF locator, combined with the RF high-precision positioning system, can better locate the position of the rail vehicle with an accuracy of 1 cm.

[0003] However, some RF locators are expensive. If they are directly installed on a rail vehicle without an external mission protection mechanism, the locator may be damaged when hit by flying objects when traveling at high speed, resulting in the loss of the positioning signal.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 A high-precision positioning device for a rail vehicle comprises an RF locator body 1, the RF locator body 1 is installed in a protection mechanism 2, the protection mechanism 2 is arranged on a side wall surface of a rail vehicle 4, and a padlock 3 is arranged on the protection mechanism 2;

[0024] The protection mechanism 2 includes a protection box 23, a closable protection door 21 is provided on one side of the protection box 23, a padlock 3 is provided on the outside of the protection door 21, a rain shield 22 is provided on the upper end of the protection box 23, the RF locator body 1 is installed in the protection box 23, and a power box 5 is installed on one side of the RF locator body 1.

[0025] Among them, tempered glass 211 is arranged on the surface of the protective door 21, and a first lock plate 212 is welded in the middle of the side wall of one side of the protective door 21. The tempered glass 211 allows the operator to directly observe the situation inside the protective box 23, and facilitates the observation of the power supply of the power box 5 and the operating status of the RF locator body 1.

[0026] In addition, a second locking plate 231 is welded in the middle of the side wall on one side of the protective box 23, and a plurality of heat dissipation holes 232 are opened through the bottom wall of the protective box 23. Mounting holes 233 are symmetrically opened on the inner wall on one side of the protective box 23. A fixing component 8 is installed at the mounting hole 233. The mounting hole 233 is convenient for installing the fixing component 8, and then the fixing component 8 is screwed into the bolt hole matched with it opened on the surface of the rail car 4. This design makes it possible to open the protective door 21 for disassembly and installation from the inside, and prevent someone from disassembling the protective mechanism 2 from the outside and taking away the equipment inside.

[0027] Moreover, through holes are provided on the second lock plate 231 and the first lock plate 212, and the first lock plate 212 can be inserted between the second lock plates 231 on the upper and lower sides. The lock beam of the padlock 3 is hung on the first lock plate 212 and the second lock plate 231. The padlock 3 can lock the first lock plate 212 and the second lock plate 231 together so that they cannot be separated, thereby locking the protective door 21.

[0028] In addition, a plurality of limit plates 6 are symmetrically arranged on the inner wall of the protective box 23 with the mounting hole 233, and a placement rack 7 is arranged on the inner wall surface adjacent to the limit plate 6. The limit plate 6 is L-shaped, and a first rubber pad 61 is attached to the surface of one side of the limit plate 6. The RF locator body 1 is inserted between the limit plates 6 on both sides. The limit plate 6 can effectively limit and clamp the RF locator body 1 to fix it. At the same time, the first rubber pad 61 can enhance a certain friction force. After the outer wall of the RF locator body 1 contacts the first rubber pad 61, the RF locator body 1 can be well prevented from falling out.

[0029] Among them, the inner surface of the placing rack 7 is affixed with a second rubber pad 71, and the power box 5 is placed on the placing rack 7. The placing rack 7 can be used to place the power box 5 for supplying power to the RF locator body 1, and the second rubber pad 71 can enhance a certain friction force. After the outer wall of the power box 5 contacts the second rubber pad 71, it can well prevent the power box 5 from falling out.

[0030] In this embodiment, when the RF locator body 1 is installed on the rail car 4, the protective mechanism 2 is first installed on the rail car 4. First, according to the position of the mounting hole 233, a bolt hole that is compatible with the fixing component 8 is drilled on the surface of one side of the body of the rail car 4. Then, after aligning the mounting hole 233 of the protective box 23, the fixing component 8 is screwed in, so that the protective box 23 is installed on the rail car 4. Then, the RF locator body 1 can be inserted between the limit plates 6 on both sides, the power box 5 is placed in the placement rack 7, and then the two are connected.

[0031] After installing the RF locator body 1 and the power box 5, you can close the protective door 21 so that the first lock plate 212 is buckled between the second lock plates 231 on both sides, then open the padlock 3, pass the lock beam through the through holes of the first lock plate 212 and the second lock plate 231, and lock the padlock 3. This completes the installation of the RF locator body 1.

[0032] When the rail vehicle 4 is running, the heat dissipation holes 232 can also play a certain heat dissipation role. The upper rain shield 22 is convenient for preventing rainwater from entering the interior of the protection box 23 through the protection door 21 when the rail vehicle 4 is not running on rainy days.

[0033] In the utility model, a protective mechanism 2 is arranged outside the RF locator body 1, so that the RF locator body 1 can be protected by the protective box 23, so that when a flying object flies while the rail vehicle 4 is traveling, it can be blocked by the protective box 23, thereby playing a better protective role, and the overall anti-theft performance of the protective mechanism 2 is good, and the protective mechanism 2 can only be disassembled by opening the protective door 21.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
