Description

Technical Field

[0001] The invention relates to the technical field of brake hose disconnection training, in particular to an intelligent brake hose disconnection training device. Background Art

[0002] Railway shunting operation is an important part of railway transportation production, and the removal and installation of vehicle brake hoses is an indispensable operation link in shunting operation; the brake hose is a hose connecting the brake main pipes of two vehicles, and a connector is installed at its end. The operation process of removing or connecting the connectors of the two brake hoses between the locomotive and the vehicle is called removing or connecting the brake hose. Before removing the brake hose, the angle plug at the root of the brake hose must be closed to plug the air path of the brake hose. After connecting the brake hose, the angle plug must be opened to connect the brake hose air path and check whether the brake hose is leaking. The skill of removing and installing the brake hose is a basic skill that shunting operators should possess.

[0003] Therefore, we propose an intelligent training device for disconnecting and connecting brake hoses to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose an intelligent training device for disconnecting and connecting brake hoses.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An intelligent training device for connecting and disconnecting brake hoses comprises a mechanical system, an electrical control system and a software system. The mechanical system further comprises a display, a pipeline pressure sensor, an air compressor, five simulation vehicles, a pressure regulating mechanism and a speed regulating mechanism. A brake hose group is arranged between adjacent simulation vehicles. The brake hose group has two brake hoses. The brake hose is connected to the simulation vehicle through an angle plug. Two simulation vehicles have respective button boxes on their coupling parts. The button boxes are divided into button box one and button box two.

[0007] The electrical control system includes PLC programmable controller, analog quantity acquisition module, switching power supply, distribution box, button box, proximity switch sensor, pressure sensor, and computer;

[0008] The software system consists of lower computer programs, upper computer acquisition middleware, and assessment management software.

[0009] Preferably, the five simulated vehicles include simulated vehicle one, simulated vehicle two, simulated vehicle three, simulated vehicle four and simulated vehicle five.

[0010] Preferably, in the mechanical system, a five-vehicle four-gear structure is simulated, and angled plugs and brake hoses are installed between each gear.

[0011] Preferably, in the mechanical system, operation button box one and button box two are installed in the simulated vehicle one and simulated vehicle five.

[0012] Preferably, in the mechanical system, button box one has a start test button and an emergency stop switch button, and button box two has an end test button and an emergency stop switch button.

[0013] Preferably, in the mechanical system, the platform notifies the assessment system to start the test timing by pressing the start test button and the end test button, and presses the emergency stop switch button to cut off the power supply in an emergency.

[0014] Preferably, in the mechanical system, air is supplied in series to all hoses through an air compressor, and the wind pressure and wind speed can be adjusted and managed through a pressure regulating mechanism and a speed regulating mechanism.

[0015] Preferably, in the electrical control system, proximity switch sensors are installed at the opening and closing positions of the corner plug doors of each vehicle.

[0016] Preferably, in the electrical control system, a pressure sensor is installed at the end of the simulated five-car.

[0017] Preferably, in the electrical control system, the button box input, the sensor and the conduction connection status of each hose are collected in real time through the PLC programmable controller, and the data are sent back to the computer for analysis and processing.

[0018] Preferably, an air pressure sensor is also installed in the electrical control system, which can accurately determine whether the rubber ring of the hose connected by the trainee is in good condition by detecting the real-time change of the air pressure value.

[0019] Preferably, in the software system, the host computer acquisition middleware is mainly used to collect the status of the transfer equipment and is used during system debugging, and is minimized by default after startup.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This system can not only meet the students' daily training needs, but also conduct on-site assessments. It uses electronic components such as proximity switches and pressure sensors, which can provide real-time feedback on the status of the corner plug and the system pressure value. While the students are operating, the large screen will display the switch status of the corner plug and the connection status of the brake hose synchronously with animation, making the training more reasonable and effective. The system software has clear and intuitive screens, and also has functions such as performance record management, which can meet the students' practical training and skill assessment of removing and installing brake hoses.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] In the description of the present invention, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The conjunction "consisting of excludes any unspecified element, step, or component. If used in a claim, this phrase renders the claim closed-ended so that it does not include materials other than those described, except for conventional impurities associated therewith. When the phrase "consisting of" appears in a clause of the body of a claim rather than immediately following the subject matter, it limits only the elements described in that clause; other elements are not excluded from the claim as a whole.

[0033] Approximate terms in the specification and claims are used to modify quantities, indicating that the present invention is not limited to the specific quantity, but also includes acceptable and modified parts close to the quantity without causing changes in the relevant basic functions. Accordingly, the use of "about", "approximately", etc. to modify a numerical value means that the present invention is not limited to the exact numerical value. In some examples, the approximate terms may correspond to the accuracy of the instrument for measuring the numerical value. In the specification and claims of this application, range limitations can be combined and / or interchanged, and if not otherwise stated, these ranges include all subranges contained therein.

[0034] In addition, the indefinite articles "a" and "an" before the elements or components of the present invention have no restrictions on the quantity requirements (i.e. the number of occurrences) of the elements or components. Therefore, "a" or "an" should be interpreted as including one or at least one, and the elements or components in the singular form also include the plural form, unless the number is obviously intended to be in the singular form.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figure 1-6 , an intelligent training device for connecting and disconnecting brake hoses, including a mechanical system, an electrical control system and a software system. The mechanical system also includes a display, a pipeline pressure sensor, an air compressor, five simulation cars, a pressure regulating mechanism, and a speed regulating mechanism. A brake hose group 6 is also arranged between adjacent simulation cars. The brake hose group 6 has two brake hoses, and the brake hose is connected to the simulation car through a folding plug door 9. Two simulation cars have button boxes on their hook parts, and the button boxes are divided into button box one 7 and button box two 8. The five simulation cars include simulation car one 1, simulation car two 2, simulation car three 3, simulation car four 4 and simulation car five 5;

[0037] In the mechanical system, a five-car 5 four-gear structure is simulated, and an angle plug gate 9 and a brake hose are installed between each gear. The simulated car 1 and the simulated car 5 are installed with an operation button box 1 7 and a button box 2 8. The button box 1 7 has a start test button and an emergency stop switch button, and the button box 2 8 has an end test button and an emergency stop switch button. The platform notifies the assessment system to start the test timing by pressing the start test button and the end test button, and presses the emergency stop switch button to cut off the power supply in an emergency; in the system, an air compressor is used to supply air in series to all hoses, and the wind pressure and wind speed can be adjusted and managed through the pressure regulating mechanism and the speed regulating mechanism.

[0038] Reference Figure 1-6 , an intelligent training device for connecting and disconnecting brake hoses, the electrical control system includes a PLC programmable controller, an analog quantity acquisition module, a switching power supply, a distribution box, a button box, a proximity switch sensor, a pressure sensor, and a computer; in the electrical control system, a proximity switch sensor is installed at the opening and closing positions of the corner plug door of each vehicle, and an operation button box 1 7 and a button box 2 8 are installed on the simulated vehicle 1 and the simulated vehicle 5, and a pressure sensor is installed at the end of the simulated vehicle 5. The button box input, the sensor and the conduction connection status of each hose are collected in real time through the PLC programmable controller, and the data are sent back to the computer for analysis and processing; an air pressure sensor is also installed in the system, which can accurately determine whether the rubber ring of the hose connected by the trainee is in good condition by detecting the real-time change of the air pressure value.

[0039] Reference Figure 1-6 , an intelligent training device for disconnecting and connecting brake hoses, the software system includes a lower computer program, a host computer acquisition middleware, and an evaluation management software; the host computer acquisition middleware is mainly used to collect the status of transfer equipment and is used during system debugging, and is minimized by default after startup.

[0040] The following parameter requirements are imposed on system technology:

[0041] Working environment: temperature range is 0℃~55℃, relative humidity ≤90%;

[0042] Power supply: AC220V±20V / 50Hz, 3.5KW, ground resistance <4Ω;

[0043] Wind source requirements: ≥0.5Mpa;

[0044] System dimensions: 4800*1400*1450mm (length*width*height);

[0045] Weight: 0.5T.

[0046] Another thing to note is that the signal line is laid inside the brake hose. After the hose is connected, it is necessary to check whether it is connected properly. However, because the hose is a rubber product, it cannot conduct electricity and it is not convenient to install sensors for detection. A wire is laid inside each hose as a signal line. This avoids external wiring and affects the appearance and student training, as shown by the red line in the figure below;

[0047] The pressure sensor value is monitored to determine whether there is leakage in the hose connection, thereby determining whether the hose connection operation meets the standards.

[0048] The examination process is as follows:

[0049] (1) Turn on the system power and air compressor, make sure the emergency stop buttons on the two button boxes are in the open state, turn on the computer and start the host computer acquisition middleware, assessment management software, and test management software;

[0050] (2) Students select students and test items ([Remove management] or [Take over management]) on the test management software interface and enter the test interface;

[0051] (3) The student presses the button [Start Test] on the button box 7, the [Test Status] indicator on the button box lights up, the test starts timing, and the status of the 3D model is updated in real time;

[0052] (4) Trainees perform operations such as opening and closing corner doors and disconnecting and connecting hoses as required;

[0053] (5) After the trainee has completed the operation, he / she presses the button [End Test] on the button box 28, and the [Test Status] indicator on the button box turns off. At this time, the test of the assessment program ends. If it is a takeover exercise, the system will also detect the change of the pipeline air pressure through the air pressure sensor to determine whether the hose connection is qualified.

[0054] (6) Close the program, computer, and power supply one by one.

[0055] The main electrical components list is as follows:

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0059] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
