Description

Technical Field

[0001] This utility model belongs to the field of rail transit vehicle commissioning technology, and specifically relates to an automatic sand injection device for rail transit vehicle sand boxes. Background Technology

[0002] During the commissioning of high-speed trains, a sand-spreading function test is required. After the test, the sand box cover needs to be opened and quartz sand needs to be poured into the sand box. Currently, there is no device on the market that can automatically pour sand into the sand box. Therefore, sand is poured into the sand box little by little by hand using a measuring cup. This operation requires two people to work simultaneously in each carriage, and the working time is about 20 minutes per carriage, which is a significant waste of manpower. At the same time, during the sand pouring process, due to the narrow space, the quartz sand may fall into hidden places in the equipment compartment due to hand tremors when the measuring cup is inserted. This is very difficult to clean, and if it is not cleaned properly, it will affect the safety of train operation. Therefore, it is urgent to develop a device that can automatically pour sand into the sand box. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Reference Figure 1 , Figure 2 An automatic sand-filling device for a sand box in a rail transit vehicle includes a frame 1, which is a box structure formed by inserting tubes. To ensure product strength, the tubes are square tubes, which are fixed together as a whole by bolts. For easy movement, the bottom of the frame 1 is equipped with casters 5. In addition, a handrail 11 extends from the top of the frame 1 to enable portable movement.

[0025] A sand collection box 2 is installed inside the frame 1. The bottom of the sand collection box 2 is connected to a sand pump 3. The sand pump 3 is connected to a sand injection hose 4. A conveying blade 41 is installed inside the sand injection hose 4. (Refer to...) Figure 3 The sand pump 3 includes a drive motor 31, which drives the conveying blades 41 to rotate via a pulley 32. For portability, a power module is installed within the frame 1 to provide power to the sand pump 3. For easy charging, the power module is a rechargeable power module.

[0026] For ease of control, the frame 1 includes a control switch 6 for controlling the operation of the device. To achieve automatic operation, a sand quantity detection device is installed inside the sand collection box 2, and this device is connected to the control switch 6. Quartz sand is introduced from the sand collection box 2 into the sand tank of the trainset via the sand injection hose 4. When the sand injection quantity reaches the required test value, the control switch 6 will stop the operation of the sand pump 3, completing the sand filling process for the trainset. If the sand quantity detection device detects insufficient sand in the sand collection box 2, the control switch 6 will stop the operation of the sand pump 3, thus achieving automatic start and stop of the sand injection function.
