Description

Technical Field

[0001] This utility model belongs to the field of locomotive functional testing, specifically relating to a sand collection and metering device for locomotive testing. Background Technology

[0002] During train operation, the wheels and rails gradually become smooth due to long-term friction. While this smoothness improves ride comfort, it significantly reduces friction during starting, braking, or climbing in rainy or snowy weather. If the locomotive spins, the wheel treads can peel off, potentially leading to rail deformation or breakage, and increasing the risk of loss of control. This is where the sandbox system becomes crucial. A key component of locomotive anti-skid technology, the sandbox system cleverly incorporates specialized sandboxes containing rigorously selected and processed anti-skid materials along the direction of wheel travel. When the train needs to increase friction between the wheels and rails, a specially designed sandblasting system quickly activates, spraying sand with a specific particle size, typically within the two to three millimeter range, onto the rails. By spraying sand, the sandbox system rapidly fills the gaps between the wheels and rails, increasing the roughness of the contact surface and significantly improving friction, ensuring stable train operation.

[0003] Excessive sand spraying will lead to waste of sand and gravel, while insufficient spraying will often cause trains to start unsuccessfully. Therefore, it is often necessary to test the sand spraying system of the sand box system in advance, measure the weight of the sprayed sand and gravel, and then determine whether the sand box system can work perfectly. However, the sprayed sand and gravel are often difficult to collect, and it is difficult to determine whether the locomotive sand spreading system can operate normally by measurement. Therefore, there is an urgent need to design a sand and gravel collection and measurement device. Utility Model Content

[0035] Example 1

[0036] This embodiment mainly introduces a sand collection and metering device for locomotive testing, including a collection box 1 and an arc-shaped receiving plate 2;

[0037] The top left side of the collection box 1 is provided with a raised left curved edge 3;

[0038] The top right side of the collection box 1 is provided with a raised right curved edge 4;

[0039] The arc-shaped support plate 2 is set on the top of the right bend 4;

[0040] The collection box 1 is equipped with a sand collection box 10, and a weight sensor is installed between the bottom of the sand collection box 10 and the collection box 1.

[0041] A display device is provided on the left curved edge 3 and connected to a weight sensor to display the weight inside the collection box.

[0042] The arc-shaped receiving plate is set at the bottom of the sand outlet of the sand box system to receive sand and transfer it to the collection box 1; a protrusion is provided on the other side of the bottom of the right bend to engage the rail.

[0043] Furthermore, the height of the left curved edge 3 is higher than that of the right curved edge 4. When sand and gravel fall into the collection box, the splashed sand and gravel will not leak out due to the height of the collection box, since the height of the left curved edge 3 is higher than that of the right curved edge 4.

[0044] Furthermore, the arc-shaped receiving plate 2 has an S-shaped configuration, which facilitates the sand and gravel sprayed from the sand box system to receive a buffer force during the spraying process, avoiding the splashing of sand and gravel. Since the arc-shaped receiving plate is rotatable, the sand and gravel can fall smoothly into the collection box as the arc-shaped receiving plate rotates.

[0045] Furthermore, a damping hinge is provided on the top panel of the right curved edge 4, and a magnetic adjustment plate is provided on the damping hinge. The arc-shaped receiving plate 2 is magnetically attached to the magnetic adjustment plate. When sand and gravel fall onto the arc-shaped receiving plate 2, the arc-shaped receiving plate 2 rotates accordingly, thereby transferring the sand and gravel on the arc-shaped receiving plate 2 into the sand collection box 10. The arc-shaped receiving plate 2 can also be magnetically replaced as needed.

[0046] In addition to the damping hinge method described above, this embodiment also provides another sand and gravel transfer device, please refer to... Figures 1-3 Specifically, a rotating bracket is provided on the top panel of the right curved edge 4, and an eccentric fixing block 5 is fixedly provided at the bottom of the arc-shaped support plate 2. The eccentric fixing block 5 is engaged with the rotating shaft 6 of the rotating bracket.

[0047] Furthermore, the rotating bracket includes a rotating shaft 6, a left bracket 7, and a right bracket 8;

[0048] The left bracket 7 and the right bracket 8 are respectively fixed to the top panel of the right bend 4 by bolts;

[0049] The left bracket 7 is provided with a first rotating hole, and the right bracket 8 is provided with a second rotating hole. The rotating shaft 6 passes through the first rotating hole and the second rotating hole, thereby enabling the rotating shaft 6 to rotate, which in turn drives the arc-shaped receiving plate 2 on the rotating shaft 6 to rotate.

[0050] Furthermore, the rotating shaft 6 is provided with a groove 9 for engaging the eccentric fixing block 5.

[0051] This application discloses a sand collection and metering device for locomotive testing, comprising a collection box and an arc-shaped receiving plate. The collection box has a left-hand curved edge at its top left side and a right-hand curved edge at its top right side. The arc-shaped receiving plate is positioned on top of the right-hand curved edge. A sand collection box is located within the collection box. A weight sensor is installed between the bottom of the sand collection box and the collection box. The weight sensor is connected to a display device on the left-hand curved edge. When sand from the sand box system flows onto the arc-shaped receiving plate, the plate rotates under the applied weight pressure, pouring the sand into the sand collection box. The display device shows the weight, thus enabling precise collection and weighing of the sand.
