[0002] In the overhaul operation of railway freight cars, the flaw detection operation is responsible for inspecting internal cracks of products and is a crucial link in the freight car overhaul operation. In the flaw detection operation, magnetic suspension liquid flaw detection is widely welcomed due to its advantages of fast response speed, low energy consumption, and simple control.
[0003] In the process of using magnetic suspension liquid for flaw detection, it is necessary to place the fully mixed magnetic particle solution in a conical flask and let it stand and precipitate for a specified time, then observe the volume value of the magnetic particles at the bottom of the conical flask, and further analyze to obtain the flaw detection result of the product.
[0004] In the prior art, generally, a stopwatch is used by manual operation to time the precipitation time of the magnetic suspension liquid. However, when the detection volume is large, the process of manually measuring the precipitation time of the magnetic suspension liquid is easily affected by human uncertain factors, resulting in inaccurate timing. Content of the Utility Model
[0005] In order to solve the technical problem that the timing is inaccurate due to being easily affected by human uncertain factors when manually measuring the precipitation time of the magnetic suspension liquid in the background art, the utility model provides a magnetic suspension liquid precipitation timer.

[0008] Optionally, the placement rack is fixedly connected to the main body, and a placement groove is arranged on the placement rack, and the placement groove is used for placing the container.

[0017] The beneficial effects of the present utility model are as follows:
[0018] The present utility model provides a magnetic suspension liquid precipitation timer, which includes a main body, a placement rack, an induction component and a timing component. When a container is placed on the placement rack, the induction component detects the container and thus feeds back a corresponding electrical signal to the timing component.

[0026] When performing maintenance operations on railway freight cars using magnetic suspension liquid, the flaw detection operation is used to check for internal cracks in the product, which is a crucial link in the maintenance operations of railway freight cars. During the process of using magnetic suspension liquid for flaw detection, it is necessary to place the fully mixed magnetic particle solution in a conical flask and let it stand and precipitate for a specified time, then observe the volume value of the magnetic particles at the bottom of the conical flask, and further analyze to obtain the flaw detection result of the product. For example, according to the regulations on flaw detection operations in the "Regulations for the Maintenance of Railway Freight Car Wheelsets", "After fully stirring the magnetic suspension liquid evenly, use a conical long-neck precipitation tube to collect 100 milliliters of the magnetic suspension liquid sprayed from the nozzle, let it stand and precipitate. The water-based magnetic suspension liquid stands for 30 to 35 minutes, and the oil-based magnetic suspension liquid stands for 40 to 45 minutes, and then observe the volume value of the magnetic powder at the bottom of the conical long-neck precipitation tube", so as to judge whether there are cracks inside the product.
[0027] However, in existing operations, the precipitation time of the magnetic suspension liquid is generally timed manually using a stopwatch. During the timing process, it is very easy to be affected by human uncertain factors, resulting in inaccurate timing and affecting the internal flaw detection result of the product; at the same time, it also requires a special person to specifically perform the stopwatch timing work, consuming manpower.
[0028] See Figure 1 and Figure 2 , which shows a schematic diagram of a magnetic suspension liquid timer described in the present application. The magnetic suspension liquid precipitation timer includes: a main body 1, a placement rack 2, an induction component 3 and a timing component 4; wherein, the placement rack 2 is connected to the outside of the main body 1 and is used for placing containers; the induction component 3 is arranged on the main body 1 or the placement rack 2 and is electrically connected to the timing component 4. The induction component 3 is used to detect whether a container is placed in the placement rack 2 and feedback a signal to the timing component 4; the timing component 4 starts or ends the timing state based on the signal feedback by the induction component 3.
[0029] In this embodiment, a magnetic suspension liquid timer is provided. When the magnetic suspension liquid precipitation timer is in use, when the induction component 3 detects that the container is placed on the placement rack 2, the induction component 3 feeds back a corresponding electrical signal to the timing component 4, specifically, it can be a first electrical signal. After receiving the first electrical signal, the timing component 4 starts the timing state and times the precipitation time; or when the induction component 3 detects that the container is taken away from the placement rack 2, the induction component 3 feeds back a corresponding electrical signal to the timing component 4, specifically, it can be a second electrical signal. After receiving the second electrical signal, the timing component 4 ends the timing state.
[0030] Specifically, the container in this embodiment can be selected as an Erlenmeyer flask, a pear-shaped magnetic powder measuring tube, or any other well-known magnetic suspension liquid container in the art. It should be noted that those skilled in the art can specifically select the type of the container according to the actual production and use requirements, and this embodiment does not make further limitations.
[0031] The magnetic suspension liquid precipitation timer provided in this embodiment avoids the technical problems of labor consumption and susceptibility to human uncertain factors caused by only relying on manual stopwatch timing in the prior art.
[0032] Furthermore, the timing component 4 can be selected as a programmable controller, a microprocessor, etc. arranged on the circuit board. By way of example, it can be selected as a 51 series single-chip microcomputer, an STM32 series single-chip microcomputer, an 8051 series single-chip microcomputer, etc. Preferably, it can be selected as the STC89C51 type. It should be noted that those skilled in the art can specifically select the type of the timing component 4 and the circuit board according to the actual production and use requirements, and this embodiment only provides a relatively preferred selection scheme.

[0034] In this embodiment, a placement groove 2-1 should be provided on the placement rack 2. In the specific application process, the container containing the fully mixed magnetic particle solution is placed in the placement groove for static precipitation. When the container is placed on the placement groove 2-1, the induction component 3 detects the container, and the induction component 3 feeds back a corresponding electrical signal to the timing component 4, specifically, it can be a first electrical signal. After receiving the first electrical signal, the timing component 4 starts the timing state and times the precipitation time; or when the induction component 3 detects that the container is taken away from the placement groove 2-1, the induction component 3 feeds back a corresponding electrical signal to the timing component 4, specifically, it can be a second electrical signal. After receiving the second electrical signal, the timing component 4 ends the timing state.
[0035] Furthermore, the placement rack 2 can be set as a clamping bracket or a self-locking structure.

When the container is placed in the placement slot 2-1, the container generates pressure on the pressure sensor, so that the pressure sensor feeds back a corresponding electrical signal to the timing component 4, which can be specifically a first electrical signal. After receiving the first electrical signal, the timing component 4 starts the timing state and counts the sedimentation time; or when the container is removed from the placement slot 2-1, the pressure sensor detects that the pressure disappears, and the pressure sensor feeds back a corresponding electrical signal to the timing component 4, which can be specifically a second electrical signal. After receiving the second electrical signal, the timing component 4 ends the timing state.
[0038] Furthermore, the pressure sensor should include a plurality of pressure detection points, and the plurality of pressure detection points are evenly arranged in the placement groove 2 - 1 , so as to accurately obtain the placement status of the container.

Specifically, the infrared sensor should detect the placement slot 2-1. When it is detected that a container is placed in the placement slot 2-1, the infrared sensor feeds back a corresponding electrical signal to the timing component 4, which may be a first electrical signal. After the timing component 4 receives the first electrical signal, it starts the timing state and counts the sedimentation time; or when the container is taken away from the placement slot 2-1, the infrared sensor detects that the container is taken away from the placement slot, and feeds back a corresponding electrical signal to the timing component 4, which may be a second electrical signal. After the timing component 4 receives the second electrical signal, it ends the timing state.
