Description

Technical Field

[0001] The present invention relates to the technical field of speed control equipment for railway hump marshalling yards, and particularly to an accessory box for air source treatment components of a vehicle retarder. Background Art

[0002] At present, after years of development, pneumatic gravity vehicle retarders have become important speed control equipment in domestic railway hump marshalling yards. Pneumatic gravity vehicle retarders are popular among users because of their reliable performance, low maintenance volume, and less environmental pollution. Up to 80% of the marshalling yards across the country use this equipment.

[0003] An accessory box for air source treatment components is provided for the pneumatic gravity vehicle retarder to perform water separation, filtration, and oil mist treatment on the compressed air entering the reversing valve and the cylinder, ensuring the normal operation of the retarder and improving the reliability and service life of the retarder.

[0004] The main pneumatic components of the accessory box for air source treatment components are a water separator filter and an oil mist lubricator. For easy observation, the filter cups and oil mist cups of these two components are made of transparent organic materials.

[0005] The accessory box for air source treatment components is a weak link in the maintenance of the retarder. During the service life of the retarder, the accessory box needs to be regularly opened for maintenance, the water separator filter needs to be drained and replaced regularly. Sometimes, the water separator filter and the oil mist lubricator have to be replaced as a whole. This requires the accessory box to have the functions of convenient maintenance and quick replacement, and at the same time requires the accessory box to have good sealing performance.

[0006] Existing ordinary accessory boxes, such as Figure 1 shown, have a plug-in type box cover, which is not divided into left and right installations, facilitating production, manufacturing, and installation. However, during use, the box cover is prone to deformation, increasing the difficulty of plugging and unplugging the box cover, with poor sealing performance and dust prevention effect, and requires regular cleaning. In addition, the two sides of the box cover are close to the filter cup and the oil mist cup. In summer, when exposed to the sun, it is easy to cause uneven heating of the cup bodies of the filter cup and the oil mist cup, resulting in the problem of cup body bursting.

[0007] Therefore, currently, designing a new type of accessory box has become an inevitable requirement for improving the reliability and maintainability of the retarder. Summary of the Invention

[0055] For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0056] See Figures 2 to 14 , the present invention provides an accessory box for the air source treatment element of a vehicle retarder, specifically an accessory box for the air source treatment element of a pneumatic gravity type vehicle retarder, including a box body 1 with openings (openings) at both the top and the right side;

[0057] At the front and rear ends of the left side of the top of the box body 1, they are respectively hinged to the lower left side of the box cover 8 through a hinge 9;

[0058] The right bottom end of the box cover 8 has a right side guard plate 80, and this right side guard plate 80 is hermetically buckled on the right opening of the box body 1, and the shape and size of this right side guard plate 8 correspond to and match the shape and size of the right opening of the box body 1;

[0059] Among them, at the middle positions of the top of the front and rear ends of the box body 1, there is respectively a first main pipeline installation notch 101;

[0060] The two first main pipeline installation notches 101 are respectively fixedly connected to the left and right ends of the main pipeline 10 through a pair of clamps 2;

[0061] It should be noted that the main pipeline is a pipeline in a pneumatic gravity type vehicle retarder for transporting compressed air into the reversing valve and the cylinder, and it is an existing pipeline.

[0062] Among them, on the main pipeline 10, an oiler 11 and a water separator 12 are installed;

[0063] The oiler 11 and the water separator 12 are installed and are located in the inner cavity of the box body 1;

[0064] Among them, the front and rear ends of the box cover 8 respectively have a second main pipeline installation notch 102 at positions directly above the two first main pipeline installation notches 101.

[0065] When each first main pipeline installation notch 101 and the second main pipeline installation notch 102 directly above it are combined up and down, a pipeline through hole for accommodating the clamp 2 and the main pipeline 10 is formed.

[0066] Among them, a heat insulation board 6 is provided on the inner side of the top of the box cover 8.

[0067] In the present invention, specifically, the clamp 2 is fixedly connected to the first main pipeline installation notch 101 at the top of the box body 1 through bolts.

[0068] In the present invention, specifically, a circle of hollow sealing strips 5 is installed around the four peripheral edges of the heat insulation board 6. The outer sides of the four weeks of this circle of hollow sealing strips 5 are in close contact with the inner side wall of the top of the box cover 8. The reason for such a design is mainly to prevent solar radiation from reaching the two side plates of the accessory box, avoid the bursting of the filter cup and the oil cup due to local heating, block conduction, radiation, and convection. The hollow sealing strips on the heat insulation board 6 have the same structure as the hollow sealing strips on the box cover 8 and can be used interchangeably.

[0069] In the present invention, specifically, refer to Figure 3 、 Figure 8 As shown, a same circle of hollow sealing strips 5 is installed around the front and rear side edges at the bottom, the left side edge of the box cover 8, and the bottom edge and the front and rear side edges of the right side guard plate 80.

[0070] In the present invention, specifically, a circle of limit convex plates 101 is provided around the top and the inner side edge on the right side of the box body 1.

[0071] When the box cover 9 is closed on the box body 1, the limit convex plates 101 are in close contact with the hollow sealing strips 5 on the box cover 8 and the right side guard plate 80.

[0072] In the present invention, specifically, a sealing rubber sheet 4 is provided between the upper and lower side surfaces of the main pipeline 10 and the clamp 2, so as to enhance the sealing effect.

[0073] In the present invention, specifically, for each pair of clamps, the left and right ends of the upper clamp 2 respectively have a sealing cover 201.

[0074] Among them, the sealing cover 201 at the left end of the clamp is located outside the limit convex plate 101 (i.e., on the side away from the inner cavity of the box body 1).

[0075] The sealing cover 201 at the right end of the clamp is located inside the limit convex plate 101 (i.e., on the side close to the inner cavity of the box body 1).

[0076] Therefore, through the design of the internal and external dislocation distribution of the two sealing covers 201, the sealing effect of the clamp part can be increased.

[0077] In the present invention, specifically, refer to Figure 3 、 Figure 9 As shown, at the middle part of the lower side of the right side guard plate 80 on the right end of the bottom of the box cover 8, a box lock 7 (such as the existing Shengjiu brand box lock with a compression function) is installed. It should be noted that the box lock 7 adopts the Shengjiu brand box lock with a compression function, which can compress the sealing strip, as Figure 9 shown.

[0078] In the present invention, specifically, refer to Figure 3 、 Figure 5 As shown, a welding joint 3 is connected to the front end of the main pipeline 10;

[0079] On the front side of the welding joint 3, there is a sealing groove 30 that is circumferentially distributed and concave;

[0080] Therefore, through the design of the sealing groove 30, when the welding joint 3 and the pipeline joint 31 are installed, the sealing ring between the welding joint 3 and the pipeline joint 31 is not likely to fall off. It should be noted that the front side of the original welding joint has a sealing stop 32.

[0081] In the present invention, specifically, refer to Figure 3 、 Figure 13 As shown, a covered terminal block 13 is installed on the inner side of the bottom of the box body 1;

[0082] On the top of the covered terminal block 13, a hollow transparent glass cover 130 with an open top is snap - connected.

[0083] It should be noted that for the present invention, by adopting the method of adding a glass cover to the terminal block, oil mist can be prevented from invading the terminal block and damaging the terminal block. Figure 12 Shown is the terminal block without a glass cover originally.

[0084] In the present invention, specifically, the hinge 9 includes an upper hinge 91 and a lower hinge 92;

[0085] Among them, the upper hinge 91 and the lower hinge 92 are connected by a pin shaft 90;

[0086] The upper hinge 91 and the lower hinge 92 are respectively welded to the box cover 8 and the box body 1,

[0087] Specifically, a flipping limit part is added at a preset position on the lower hinge 92.

[0088] In the present invention, specifically, a filter screen is additionally provided on the oil suction pipe of the oiler 11.

[0089] Based on the above technical solutions, for the present invention, as an improved accessory box, as Figure 2 shown, the box cover adopts a flip type and needs to be installed separately on the left and right during assembly (the left and right air inlets are divided facing the box cover), and the main pipeline and the box body are fixed and assembled by a clamp. The widths on both sides of the box are increased, and heat insulation plates are added.

[0090] Compared with the prior art, the accessory box of the vehicle reducer air source treatment element provided by the present invention has the following beneficial effects:

[0091] 1. The box cover of the present invention adopts a flip cover method, which is convenient for on-site inspection and maintenance, and the sealing effect between the box body and the box cover is relatively good, reducing the on-site maintenance amount;

[0092] 2. The present invention places the main pipeline at the joint of the box body and the box cover, which facilitates on-site installation and the replacement of components such as pipelines, filters, and oil misters during maintenance;

[0093] 3. The present invention adds a heat insulation plate inside the top of the box cover to prevent the filter cup and oil mist cup from being locally heated sharply due to direct sunlight, and further avoid the bursting of the cups;

[0094] 4. The present invention adds a filter screen to the oil suction pipe of the oil mist separator, which helps to avoid the problem that the reducer cannot work properly due to impurities in the oil entering the compressed air.

[0095] In summary, compared with the prior art, the accessory box of the vehicle reducer air source treatment element provided by the present invention has a scientific structural design. Its box cover adopts a flip cover method, which is not only convenient for on-site inspection, but also has excellent sealing performance between the box body and the box cover, good sealing effect, and is conducive to reducing the on-site maintenance amount.

[0096] In addition, the accessory box of the vehicle reducer air source treatment element provided by the present invention is also provided with a heat insulation plate inside the top of the box cover, which can effectively prevent the filter cup and oil mist cup on the water separator and oil mist separator from being locally heated sharply due to direct sunlight, and avoid the problem of further bursting of the cups.

[0097] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
