Description

Technical Field

[0001] This utility model relates to the field of railway signal equipment testing technology, and in particular to a force measuring instrument for switch machine contact groups. Background Technology

[0002] A switch machine is the power unit for railway turnout switching. It moves the turnout via an actuating rod fixed to the internal motor, thus changing the direction of the railway. As railway networks become denser and railway speeds increase, the performance requirements for switch machines also become more stringent. The pulling in and extending of the switch machine's actuating rod is controlled by the control center via a switch group, which is achieved by changing the direction of the electric motor. The switch group is one of the most important components of an electric switch machine, consisting of two arc-shaped contact plates and a movable contact post. The elasticity of the contact plates directly affects the tightness of their contact with the contact post. If the elasticity decreases, the contact plates need to be replaced; otherwise, poor contact may occur, posing a potential hazard to railway operation.

[0003] However, in practical applications, the main method for testing contact plate pressure is currently a handheld pressure tester. During testing, it requires manual labor to squeeze the pressure test head between the contact plate and the contact post, and to properly pry open the contact plate. The pressure data displayed by the tester varies from person to person, and the test data is not stable. Moreover, only one contact plate is tested at a time. A group of six contact plates requires six separate tests, which is time-consuming and labor-intensive, and not conducive to testing a large number of switch machine contact groups within a limited time window. Utility Model Content

[0004] This utility model discloses a force measuring instrument for switch machine contact groups, aiming to solve the technical problems mentioned in the background art above.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The force measuring instrument for switch machine contact group includes a force measuring instrument body and contact assembly. A display screen and buttons are fixedly installed on one side of the force measuring instrument body, and a first baffle, a second baffle, a first probe assembly, a second probe assembly, and a third probe assembly are fixedly installed on the other side of the force measuring instrument body.

[0007] The first probe assembly consists of a first conductive sheet and a second conductive sheet, a first pressure diaphragm and a second pressure diaphragm, and a support plate.

[0008] The support plate is designed so that the pressure of the first contact plate and the second contact plate is transmitted to the first conductive plate and the second conductive plate, and the pressure transmitted to the first pressure diaphragm and the second pressure diaphragm will not affect each other. At the same time, multiple contact plates can be tested, which saves time and effort and facilitates the testing of a large number of switch machine contact groups, thus improving the efficiency of the force measuring instrument.

[0009] The contact assembly includes a first contact piece, a second contact piece, a third contact piece, a fourth contact piece, a fifth contact piece, and a sixth contact piece, which are fixedly installed on one side of the contact assembly.

[0010] The designed contact components facilitate plug-in testing during use, and also make subsequent testing easier, thus improving the testing convenience of the force gauge.

[0011] In a preferred embodiment, a circular boss is provided on the first conductive sheet.

[0012] The circular protrusion facilitates contact between the device and the conductive sheet during use, making subsequent testing easier.

[0013] In a preferred embodiment, the support plate is provided with a first circular boss and a second circular boss on both sides.

[0014] The first and second circular bosses facilitate support and positioning during use, improving the ease of use of the component.

[0015] In a preferred embodiment, both the first pressure diaphragm and the second pressure diaphragm are provided with pressure sensing circuits.

[0016] The pressure sensing circuit allows for convenient pressure sensing during use, facilitating subsequent testing.

[0017] In a preferred embodiment, the first probe assembly, the second probe assembly, and the third probe assembly are all three identical probe assemblies.

[0018] By using multiple probe components, multiple components can be tested simultaneously during the testing process, which improves the ease of use of the force measuring instrument.

[0019] In a preferred embodiment, both the first baffle and the second baffle are provided with right-angle bosses, and the right-angle bosses are in close contact with the first right-angle edge and the second right-angle edge provided on one side of the contact assembly.

[0020] The right-angled bosses of the first and second baffles are in close contact with the first and second right-angled edges of the contact assembly, ensuring the consistency of the contact plate's state during pressure testing and thus guaranteeing the accuracy of the pressure test.

[0021] As can be seen from the above, the switch machine contact group force measuring instrument provided by this utility model has the following technical effects.

[0022] Firstly, the support plate ensures that the pressure of the first contact plate and the second contact plate is transmitted to the first and second conductive plates, and the pressure transmitted to the first and second pressure diaphragms does not affect each other. This allows for testing of multiple contact plates, saving time and effort, and facilitating the testing of a large number of switch machine contact groups, thus improving the efficiency of the force measuring instrument.

[0023] Secondly, the right-angled protrusions of the first and second baffles are in close contact with the first and second right-angled edges of the contact assembly, ensuring the consistency of the contact plate's state during pressure testing and thus guaranteeing the accuracy of the pressure test.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] Reference Figures 1-9 The force gauge for switch machine contact assembly includes a force gauge body 1 and contact assembly 2. A display screen 11 and buttons 12 are fixedly installed on one side of the force gauge body 1. On the other side of the force gauge body 1, a first baffle 13, a second baffle 17, a first probe assembly 14, a second probe assembly 15, and a third probe assembly 16 are fixedly installed. The first probe assembly 14, the second probe assembly 15, and the third probe assembly 16 are all three identical probe assemblies. The multiple probe assemblies allow for simultaneous testing of multiple components during the testing process, improving the ease of use of the force gauge. Both the first baffle 13 and the second baffle 17 are provided with right-angle bosses 171, and the right-angle bosses 171 are in close contact with the first right-angle edge 21 and the second right-angle edge 28 provided on one side of the contact assembly 2. The close contact between the right-angle bosses 171 of the first baffle 13 and the second baffle 17 and the first right-angle edge 21 and the second right-angle edge 28 of the contact assembly 2 ensures the consistency of the contact plate state during pressure testing, thereby ensuring the accuracy of the pressure test.

[0039] The first probe assembly 14 consists of a first conductive plate 141 and a second conductive plate 145, a first pressure diaphragm 142 and a second pressure diaphragm 144, and a support plate 143. The first conductive plate 141 is provided with a circular boss 1411, which facilitates contact with the conductive plate during use and facilitates subsequent testing operations. The support plate 143 is provided with a first circular boss 1431 and a second circular boss 1432 on both sides, which facilitates support and positioning operations during use and improves the ease of use of the component. The first pressure diaphragm 142 and the second pressure diaphragm 144 are both provided with pressure sensing circuits 1421, which facilitate pressure sensing operations during use and facilitate subsequent testing.

[0040] The support plate 143 ensures that the pressure of the first contact piece 22 and the second contact piece 23 is transmitted to the first conductive piece 141 and the second conductive piece 145, and then transmitted to the first pressure diaphragm 142 and the second pressure diaphragm 144 without affecting each other. At the same time, multiple contact pieces can be tested, saving time and effort, and facilitating the testing of a large number of switch machine contact groups, thus improving the efficiency of the force measuring instrument.

[0041] The contact assembly 2 includes a first contact piece 22, a second contact piece 23, a third contact piece 24, a fourth contact piece 25, a fifth contact piece 26, and a sixth contact piece 27, which are fixedly installed on one side of the contact assembly 2. The contact assembly 2 is designed to facilitate plug-in testing during use and also facilitates subsequent testing, thereby improving the testing convenience of the force measuring instrument.

[0042] Working principle: During testing, the first probe assembly 14, the second probe assembly 15, and the third probe assembly 16 of the force measuring instrument body 1 are inserted between the first contact piece 22 and the second contact piece 23, the third contact piece 24 and the fourth contact piece 25, the fifth contact piece 26, and the sixth contact piece 27 of the contact assembly 2. The right-angle bosses 171 of the second baffle 17 and the first baffle 13 are in close contact with the first right-angle edge 21 and the second right-angle edge 28 of the contact assembly 2, so that the pressure of the first contact piece 22 and the second contact piece 23, the third contact piece 24 and the fourth contact piece 25, the fifth contact piece 26 and the sixth contact piece 27 can be measured and displayed on the display screen 11. When the probe assembly is inserted into the first contact piece 22 and the second contact piece 23, the force of the first contact piece 22 and the second contact piece 23 acts on the first pressure diaphragm 142 and the second pressure diaphragm 144. The force measuring instrument body 1 collects the pressure and displays it on the display screen 11.

[0043] During testing, the first probe assembly 14 is inserted into the first contact piece 22 and the second contact piece 23. The pressure of the first contact piece 22 acts on the first conductive piece 141. The circular protrusion 1411 of the first conductive piece 141 transmits the force to the pressure sensing circuit 1421 of the first pressure diaphragm 142. The first circular protrusion 1431 on the support plate 143 is fixed. The first circular protrusion 1431 on the support plate 143 and the circular protrusion 1411 of the first conductive piece 141 press against each other against the pressure sensing circuit 1421 of the first pressure diaphragm 142. The pressure sensing circuit 1421 generates an electrical signal. The force measuring instrument body 1 collects the pressure electrical signal and displays it on the display screen 11.

[0044] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
