Description

Glove box group for arranging iron ore test environment

Technical Field

The utility model relates to a glove compartment group for arranging iron ore test environment.

Background

The train operation control system is a system for ensuring the safe and rapid operation of the train. The complete train operation control system comprises vehicle-mounted equipment and ground equipment. The transponder information receiving unit (also called "transponder Transmission Module", "Balise Transmission Module (BTM)") is a key control device in the vehicle-mounted device, and is responsible for transmitting important safety information such as a block partition length, a line speed, a line gradient, train positioning, and the like to a vehicle-mounted host unit (ATP). Therefore, the reliability of each technical index of the transponder information receiving unit has an important influence on the safety of train operation.

For this reason, the environmental suitability of a BTM must be verified before the BTM can be placed into field use. It is now common practice to place in a laboratory the various natural environments that a BTM may encounter in a practical application site and verify the environmental suitability of the BTM therein.

The iron ore environment is a common natural environment in the actual operation scene of the train, and has a deep influence on the transmission performance of the BTM. However, there is currently no facility for rapidly building iron ore environmental tests for BTMs. Instead, the tester is required to pour the prepared iron ore onto a plastic cloth on the test table and then manually scrape the iron ore to the desired thickness (e.g., 2mm or 20mm, as required by the Transponder transport System test Specification (TBT 3544-2018) No. E.5.2.4.3). This causes the following problems:

first, it is inaccurate. In particular, the iron ore particles themselves provided by the iron ore manufacturer for testing may not meet the test requirements (e.g. greater than 2mm or greater than 20 mm) in diameter; and, the thickness of the iron ore constituting the iron ore test environment is manually scraped by a tester. Both of which may cause the thickness of the iron ore overlying the reference ring or transponder to be undesirable.

Second, it takes time. This is reflected in the need for the tester to manually reject out of the iron ore that does not meet the diameter requirements and to manually scrape out the iron ore environment of the required thickness.

These not only adversely affect the results of subsequent testing, but also affect testing efficiency.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 schematically shows a cross-sectional view of a glove box set according to an embodiment of the present invention, which helps to quickly and accurately construct a satisfactory iron ore environment so as to accurately test a tested piece. Note that satisfactory iron ores 6 have already been laid in the group of containers shown in fig. 1.

As shown in fig. 1, the glove box group includes a glove box (first glove box) 100 and a glove box (second glove box) 200. Wherein, the first glove box 100 is used for bearing the tested piece 10, and the second glove box 200 is placed above the tested piece 10. Specifically, the second glove box 200 is placed on the test object 10 placed on the placement area in the first glove box 100, and the second glove box 200 has a size (x-y direction) that coincides with the test object 10.

Note that the test object 10 may be a reference ring, a transponder, or the like. Hereinafter, the present embodiment will be described taking the test object 10 as a reference ring. For example, the test object shown in fig. 1 is a reference ring to which a tail cable is connected, the tail cable extending out of the glove box along the upper surface of the iron ore 6 laid in the first glove box 100. Those skilled in the art will appreciate that the first glove box 100 of the present invention can also be used to carry other components such as transponders (not shown).

Referring to fig. 2A and 2B, the details of the first glove box 100 will be described.

As shown in fig. 2A and 2B, the first glove box 100 includes: sundries box 1, filter screen 2, support piece 3 and placing area 4.

The glove box 1 is generally rectangular. For example, the glove box body 1 is composed of a rectangular bottom plate and four side plates extending upward from the edges of the bottom plate. The shape and size of the glove box 1 are not particularly limited as long as compliance with relevant test specifications (e.g., transponder transmission system test specifications) is ensured. The glove box 1 may also be, for example, cylindrical in shape, i.e. comprise a circular or oval bottom plate and side plates extending upwards from the edges of the bottom plate. The size of the sundries box body 1 is determined according to the field size of a laboratory and the requirements of the experiment. Specifically, according to the present embodiment, the glove box 1 may be designed to have a length (x direction) of 1220 millimeters (mm), a width (y direction) of 950mm, and a height (z direction) of 300mm.

The filter screen 2 is used to pass iron ore particles into the interior of the glove box 1. The filter screen 2 is placed inside the glove box 1 and supported by a support 3 described later. Preferably, the filter screen 2 has an overall shape that conforms to the glove box 1, i.e. completely covers the interior of the glove box 1 in the x-y direction. That is, the filter net 2 is placed inside the glove box 1 such that the bottom plate of the glove box 1 can be completely covered by the filter net 2. The space between the lower surface of the filter screen 2 and the bottom plate of the glove box 1 and the interior of a hollow structure described later constitute a space for containing iron ore particles. For example, the filter net 2 has a length of 1220mm and a width of 950mm. It will be understood by those skilled in the art that the filter screen 2 may be dimensioned so as not to completely cover the interior of the glove compartment 1 in the x-y direction, but to cover the periphery of the receiving area 4. This is to surround the specimen in a satisfactory manner with the iron ore.

As best shown in fig. 2A, the filter screen 2 is formed by a plurality of hollow structures (meshes) closely arranged in sequence. The hollow structure serves to pass iron ore particles. According to the present embodiment, the hollow structure is circular and has a diameter of 2mm or less. Those skilled in the art will appreciate that the shape and arrangement of the hollow structures need not be limiting. For example, the hollow structure may be of a shape other than circular, or the hollow structure may comprise more than one shape (e.g. a mixture of circular and elliptical shapes), provided that the maximum size of iron ore particles passing therethrough is ensured to meet the requirements. In addition, the purpose of the successive close packing of the hollow structures is to pass as much iron ore as possible quickly, so that the hollow structures can also be arranged somewhat sparsely.

As is also best shown in fig. 2A, the filter screen 2 is left with a through hole in the middle, which is not for passing iron ore particles, but for passing the placement area 4 therethrough. The shape of the through-hole generally depends on the shape of the test piece (i.e., the reference ring) (or the placement area 4). The size of the through-hole generally corresponds to (is coincident with, may also be referred to as "matches") the test piece (or placement area 4). In the present embodiment, the size of the through-hole is set to 390mm (length) × 200mm (width).

The material of the filter net 2 is a non-metal material such as fabric, polyamide fiber, acryl, etc. Preferably, the non-metallic material with better support, high tensile strength and wear resistance, such as carbon fiber, is used, so that the filter screen 2 cannot sink from the middle part after being placed in the glove box body, that is, the distance between the upper surface of the filter screen 2 and the bottom surface of the glove box body is ensured to meet the requirement (for example, 2 mm). The thickness (z direction) of the filter screen 2 is not necessarily too large, and may be limited to 0.5mm or less, for example.

The support 3 is used to support the filter screen 2, thereby controlling the thickness (z direction in the drawing) of the iron ore in the glove box 1. In the present embodiment, the height of the support 3 is such that the height of the filter web 2 meets the requirements of the transponder transmission system test specification.

In one embodiment, as best shown in fig. 4A, the support 3 and the filter screen 2 may be provided as one piece. In this case, the support 3 can be regarded as an extension of the four corners of the filter screen 2. That is, the thickness at the four corners of the filter screen 2 is set to be larger than the thickness of the other portions. The height of the supporting member 3 is set to be 2mm or 20mm from the bottom surface of the glove box body to the upper surface of the filter net 2. For example, the thickness of the filter net 2 is 2mm at the four corners, and the thickness of the remaining portion is 0.5mm. Alternatively, the thickness of the filter screen 2 is 20mm at the four corners, and the thickness of the rest is 0.5mm. This results in a thickness of exactly 2mm or 20mm for the arranged iron ore particles.

In another embodiment, as best shown in fig. 4B, the support 3 and the filter screen 2 may also be two separate elements that are separate and mountable together. In this case, the support 3 holds the filter screen 2 from below as an element separate from the filter screen 2. At this time, the thickness of the filter net 2 is 0.5mm, and the thickness of the support 3 is 1.5mm or 19.5mm. The two are combined together, so that the distance between the upper surface of the filter screen 2 and the bottom surface of the sundries box body is 2mm or 20mm. The supporting member 3 may be a solid body or a hollow body. In the case where the support 3 is configured as a hollow body, the hollow thereof should have a diameter of 2mm or less so that the iron ore falling into the container through the hollow is of a desired size.

The placing area 4 is positioned on the bottom plate inside the glove box body 1, and the upper surface of the placing area is used for placing the reference ring 10. The placement area 4 passes through a through hole in the middle of the filter screen 2 so that the upper surface of the placement area 4 is flush with the upper surface of the filter screen 2 (see fig. 2B) and flush with the upper surface of the iron ore filtered by the filter screen 2 (see fig. 1). The shape and size of the placement area 4 generally depends on the shape of the object to be tested (i.e., the reference ring). The storage area 4 may be an integral part of the floor extending from the floor inside the glove box 1 or may be a separate part from the floor.

The details of the second glove box 200 will be described in detail below with reference to fig. 3A and 3B.

As shown in fig. 3A and 3B, the second glove box 200 includes: a sundries box body 7, a filter screen 8 and a supporting piece 9.

The glove box body 7 is generally rectangular. The glove compartment 7 consists, for example, of a rectangular bottom plate and four side plates extending upwards from the edges of the bottom plate, the size of which depends on the requirements of the reference ring. For example, the shape and size of the glove box 7 are not particularly limited, but are consistent with the size of the reference ring to be tested (the size in the x-y direction). According to the present embodiment, the glove box 7 may be designed to have a length (x direction) of 390mm and a width (y direction) of 200mm. The height (z direction) of the glove box 7 is not particularly limited, but should not be too high so as to exceed the laying height of the iron ore. The height of the glove box 7 is 50mm, for example. Alternatively, the glove box 7 may also be cylindrical in shape, i.e. include a circular or oval bottom plate and side plates extending upwardly from the edges of the bottom plate.

The filter screen 8 is used to pass iron ore particles into the interior of the glove box 7. The filter screen 8 is placed inside the glove box 7 and supported by a support 9 described later. The filter screen 8 has an overall shape that corresponds to the glove compartment body 7, i.e. completely covers the glove compartment body 7 in the x-y direction. That is, the filter net 8 is placed inside the glove box body 7 such that the bottom plate of the glove box body 7 can be completely covered with the filter net 8. The space between the lower surface of the filter screen 8 and the bottom plate of the glove box 7 and the interior of a hollow structure described later constitute a space for containing iron ore particles. According to the present embodiment, the filter screen 8 may be designed to have a length of 390mm and a width of 200mm.

As best shown in fig. 3A, the filter screen 8 is formed by sequentially closely arranging a plurality of hollow structures, as with the filter screen 2. The hollow structure serves to pass iron ore particles. According to the present embodiment, the hollow structure is circular and has a diameter of 2mm or less. Similar to the filter screen 2, the shape and arrangement of the hollow structures of the filter screen 8 are not necessarily restrictive, and the hollow structures may be arranged slightly sparsely, which is not described herein again.

Like the filter screen 2, the filter screen 8 is made of a non-metal material, preferably carbon fiber, and will not be described in detail.

The support 9 is similar to the support 3, and serves to support the filter screen 8, thereby controlling the thickness of the iron ore. In the present embodiment, the height of the support 9 is such that the height of the filter screen 8 meets the requirements of the transponder transmission system test code.

In one embodiment, the support 9 and the filter screen 8 may be provided as one piece. In this case, the support 9 may be regarded as an extension at four corners of the filter screen 8. That is, the thickness at the four corners of the filter mesh 8 is set to be larger than the thickness of the other portions. The height of the supporting member 9 is set so that the distance between the upper surface of the filter net 8 and the bottom surface of the glove box body is 2mm or 20mm. For example, the thickness of the filter net 8 is 2mm at four corners, and the thickness of the other portions is 0.5mm. Alternatively, the thickness of the filter screen 8 at the four corners is 20mm, and the thickness of the remaining portion is 0.5mm. This results in a thickness of exactly 2mm or 20mm for the arranged iron ore particles.

In another embodiment, the support 9 and the filter screen 8 may also be two separate elements that are separate and mountable together. In this case, the support 9 holds the filter screen 8 from below as an element separate from the filter screen 8. At this time, the thickness of the filter net 8 is 0.5mm, and the thickness of the support 9 is 1.5mm or 19.5mm. The two are combined together to ensure that the distance between the upper surface of the filter screen 8 and the bottom surface of the sundries box body is 2mm or 20mm. The supporting member 9 may be a solid body or a hollow body. In the case where the support 9 is constructed as a hollow body, the diameter of the hollow thereof should be 2mm or less so that the size of the iron ore falling into the container through the hollow is satisfactory.

Further, since there is a requirement for a metal-free space in the test environment, and it is necessary to exclude the influence of other metal environments other than the iron ore environment on the test result, the materials of the components in the first glove box 100 and the second glove box 200 are all non-metal materials.

The following describes the usage of the glove box group of the present invention in detail.

The first filter screen 2 is installed in the first glove box body 1. The tester dumps iron ore particles to one side on the filter screen 2 as shown in fig. 2B. Iron ores 6 are scraped to the other side of the first glove box using a scraper 5. In the process, iron ore particles with the diameter less than or equal to 2mm are leaked in the first sundry box through screening and filtering of meshes. The tester uses the scraper to scrape on the filter screen back and forth for several times, so that the space between the filter screen and the sundry box is filled with the iron ore particles. Thus, after the redundant iron ores on the filter screen are taken out and the filter screen is taken off, a layer of iron ores with the thickness of 2mm is formed in the first sundry box. The operation of arranging the iron ores in the second glove box is the same as above. And after iron ore environments are arranged in the first sundry box and the second sundry box, the first sundry box, the tested piece and the second sundry box are assembled. That is, a test piece is placed on the placement area in the first glove box 1, and the second glove box 2 is placed on the test piece. Alternatively, after the iron ore environment of the first glove box is arranged, the tested piece is placed, then the second glove box is placed on the tested piece, and finally the iron ore environment is arranged for the second glove box (the method is the same as that for arranging the first glove box).

According to the glove box group of the embodiment, the iron ore environment with the required thickness can be rapidly arranged, the instability of the thickness of the iron ore scraped by hands of testers and the uncertainty of the size of iron ore particles can be reduced, and the time required for arrangement can be effectively prolonged.

The utility model provides a new filter screen is used for improving because of the iron ore granule irregular leads to the condition that individual particle size has surpassed iron ore environment requirement cover thickness in the standard, highly confirms the thickness of debris incasement iron ore through the support piece at four angles of filter screen, has improved the stability and the reliability of test result. The tester can also change the thickness of the non-liquid sundries in the sundry box by changing the height (z direction) of the supporting piece, and the method is suitable for the arrangement requirements of all non-liquid sundry environments (ballast, coal, sand, iron powder and the like) under the E.5.2.4 th reference ring and the responder in TB/T3544-2018.

In addition, as described above, the above embodiments of the present invention have been described with reference to the ring as an example, but the glove box assembly of the present invention can also be applied to a transponder. For example, when the transponder is arranged instead of the reference ring, the respective constituent elements of the glove box assembly of the present invention are not changed, and it is only necessary to modify the size of the through hole of the filter net 2, the size of the placement area 4, and the size of the second glove box body to be consistent with the transponder.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
