Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment testing, in particular to a relay detection device. Background Art

[0002] Signal safety relays are mainly used in signal control systems in the fields of railways and urban rail transit, and are used to control automatic controls such as signal display, turnout action, section occupancy, ATO, ATP, etc., so they require a high safety factor. Signal safety relays usually have 4 to 8 sets of contacts, and the contacts of signal safety relays should be connected or disconnected at the same time. If the relay contacts are not synchronized, it may cause abnormal control (fault) of the signal circuit.

[0003] The reason for the deviation of relay contact action is the mechanical fatigue of the contact. Due to long-term use, the relay contacts are deformed under the action of the pull-in pressure, resulting in changes in the contact gap, which causes the contact to move in sequence and inconsistently. Therefore, in order to ensure the safe use of the relay, preventive maintenance is required regularly to adjust and correct the position of the contacts on the horizontal axis so that all contacts are closed / opened at the same time and the action is consistent.

[0004] At present, the signal safety relay intelligent comprehensive test bench (referred to as the comprehensive test bench) is usually used to test the performance parameters of the signal relay. The comprehensive test bench is mainly for qualification testing and cannot directly reflect the deviation of the relay contact in terms of action consistency. The deviation of the relay contact action consistency mainly depends on the experience of the maintenance personnel to judge by themselves, and lacks scientific and effective detection methods, resulting in relatively low maintenance efficiency.

[0035] Signal safety relays usually include multiple moving contacts, and normally open contacts and normally closed contacts that correspond to the moving contacts one by one. When the relay coil is energized, each moving contact needs to be electrically connected to the corresponding normally open contact and disconnected from the normally closed contact at the same time; when the relay coil is de-energized, each moving contact needs to be electrically connected to the corresponding normally closed contact and connected to the normally open contact at the same time, thereby realizing the relay's function of switching the circuit on and off.

[0036] Combine the following Figure 1-5The utility model describes a relay detection device.

[0037] like Figure 1 and Figure 2 As shown, the relay detection device 1 provided by the utility model includes a relay body 11 and a detection component 12; the relay body 11 is provided with a plurality of first contacts 111 and second contacts 112 corresponding to each other; the detection component 12 includes a plurality of signal detection circuits 121 and a power supply 122, each signal detection circuit 121 includes an electrical connector 123, a first signal lamp 124 and a second signal lamp 125, each first signal lamp 124 is electrically connected to one of the first contacts 111, and each second signal lamp 125 is electrically connected to one of the second contacts 112; each electrical connector 123 is electrically connected to the power supply 122, and the electrical connector 123 is provided with a first station and a second station; in the first station, each electrical connector 123 is moved to be electrically connected to the corresponding first contact 111; in the second station, each electrical connector 123 is moved to be electrically connected to the corresponding second contact 112.

[0038] In this embodiment, the relay detection device 1 is generally used to detect the consistency of contact actions of various types of relays. The relay body 11 can be a test box, which is generally used to place the relay to be tested; a plurality of first contacts 111 correspond one by one to one of the normally open contacts or normally closed contacts of the relay, and a plurality of second contacts 112 correspond one by one to the normally open contacts or normally closed contacts of the relay; by setting a plurality of signal detection circuits 121 and a power supply 122, the signal detection circuit 121, the power supply 122 and each first contact 111 or second contact 112 respectively constitute a separate loop, so that all contacts can be detected separately; by setting a first signal lamp 121 in each loop 4 or the second signal light 125, the on-off status of each circuit can be more intuitively displayed by turning the signal light on or off, thereby displaying the connection or disconnection status of each contact; when the electrical connector 123 is located at the first station, each electrical connector 123 is electrically connected to the corresponding first contact 111, so that the corresponding circuit is connected, so as to detect the connection status of each first contact 111; when the electrical connector 123 is located at the second station, each electrical connector 123 is electrically connected to the corresponding second contact 112, so that the corresponding circuit is connected, so as to detect the connection status of each second contact 112.

[0039] Based on the above embodiment, the detection method of the relay detection device 1 is as follows:

[0040] Turn on the power supply 122, place the electrical connector 123 in the first station, and when the connection with each first contact 111 is normal, the corresponding circuit is connected, and the first signal light 124 should light up at the same time. When the electrical connector 123 leaves the first station, the circuit is disconnected, and the first signal light 124 should go out at the same time; similarly, place the electrical connector 123 in the second station, and when the connection with each first contact 111 is normal, the corresponding circuit is connected, and the second signal light 125 should light up at the same time. When the electrical connector 123 leaves the second station, the circuit is disconnected, and the second signal light 125 should go out at the same time. If some signal lights are turned on or off in advance or lag, it means that there is an abnormality in the electrical connection of the corresponding first contact 111 or the second contact 112, that is, there is a problem with the consistency of the corresponding relay contact action, which is convenient for maintenance personnel to repair and adjust according to the specific situation. Maintenance personnel can adjust the corresponding contact spacing to gradually synchronize it. Through repeated inspection and adjustment, the purpose of synchronous action is finally achieved.

[0041] The relay detection device 1 provided by the utility model is provided with a plurality of signal detection circuits 121 and a power supply 122, and cooperates with a first contact 111 and a second contact 112, so that each contact is located in a separate detection circuit, so as to detect the electrical connection of each contact; at the same time, a first signal light 124 or a second signal light 125 is provided in each circuit, and the on-off status of the circuit is more intuitively displayed through the lighting of each signal light, so as to facilitate the detection of the connection status of each contact; in addition, by placing the electrical connector 123 at the first station or the second station, so as to simultaneously connect the circuits corresponding to all the first contacts 111 or all the second contacts 112, and through the synchronization of lighting or extinguishing the first signal light 124 or the second signal light 125, the consistency of the action of each contact of the relay is intuitively displayed, so as to facilitate the maintenance personnel to carry out repair and adjustment, improve the maintenance efficiency, and effectively solve the problem that the detection of the consistency of the action of each contact of the relay is not intuitive enough and the maintenance efficiency is low in the prior art.

[0042] In some embodiments, the detection assembly 12 further includes: an electromagnet and a pull rod; the pull rod is provided with a plurality of electrical connectors 123, and the electromagnet is provided on one side of the pull rod;

[0043] When the electromagnet is powered on, the electromagnet drives the pull rod to move upward, and the multiple electrical connectors 123 all move to the first position; when the electromagnet is powered off, the pull rod moves downward, and the multiple electrical connectors 123 all move to the second position.

[0044] In this embodiment, an electromagnet is provided, which attracts the pull rod when energized, thereby causing the pull rod to move upward and driving multiple electrical connectors 123 to move to the first station at the same time, so that the first contact 111 can be detected; when the electromagnet is powered off, the attraction force on the pull rod is lost, causing the pull rod to move downward under the action of gravity and driving multiple electrical connectors 123 to move to the second station at the same time, so that the second contact 112 can be detected; by providing a pull rod to drive multiple electrical connectors 123 to move at the same time, the consistency of the action of the electrical connector 123 is ensured, which is beneficial to detecting the consistency of the action of each contact, and the structure is simple and the use effect is good.

[0045] Specifically, in some embodiments, the electromagnet includes: an armature and a coil, the armature is connected to the pull rod, and the coil is arranged on one side of the armature.

[0046] In this embodiment, when the coil is energized, it can generate magnetic force, thereby attracting the armature, so that the armature drives the pull rod to move upward, and drives multiple electrical connectors 123 to move to the first station at the same time, so as to detect the first contact 111; after the coil is powered off, the armature drives the pull rod to move downward under the action of gravity, and drives multiple electrical connectors 123 to move to the second station at the same time, so as to detect the second contact 112. The operation is simple, the maintenance efficiency is high, the structure is simple, and the practicability is strong.

[0047] Optionally, when testing the relay, the coil can be powered on and off to drive the pull rod to move up and down, thereby driving the multiple electrical connectors 123 to move to the first station or the second station; or, the armature can be directly pushed manually to drive the pull rod to move up and down, thereby driving the multiple electrical connectors 123 to move to the first station or the second station.

[0048] In some embodiments, the first signal lights 124 are all signal lights of the same color, and the second signal lights 125 are all signal lights of the same color of another color.

[0049] In this embodiment, by setting all the first signal lights 124 connected to the first contact 111 to the same color, when the action consistency of the first contact 111 is detected, the display result is more intuitive, which is convenient for maintenance personnel to judge the action consistency of the connection point and improves the detection efficiency; for the second contact 112, this embodiment also has similar technical effects, which will not be repeated here; in addition, by setting the colors of the first signal light 124 and the second signal light 125 differently, it is convenient for maintenance personnel to distinguish between the first signal light 124 and the second signal light 125, which is conducive to observing the detection results and improving the detection efficiency.

[0050] In a specific embodiment, the first signal light 124 is a red signal light, and the second signal light 125 is a green signal light.

[0051] In this embodiment, the red signal light and the green signal light have a greater degree of distinction, which is beneficial for maintenance personnel to observe the detection results and improve detection efficiency.

[0052] like Figure 2 As shown, in some embodiments, the anode of each first signal lamp 124 is electrically connected to the corresponding first contact 111, the cathode of each first signal lamp 124 is electrically connected to the ground terminal of the power supply 122, and each electrical connector 123 is electrically connected to the power supply terminal of the power supply 122.

[0053] In this embodiment, each first contact 111, each first signal light 124, the power supply 122 and each electrical connector 123 are connected end to end in sequence to form a loop. When the electrical connector 123 moves to the first workstation, the electrical connector 123 is electrically connected to the first contact 111, and the entire loop is connected, which is convenient for detecting the first contact 111. The structure is simple and practical.

[0054] like Figure 2 As shown, in some embodiments, the anode of each second signal lamp 125 is electrically connected to the corresponding second contact 112, the cathode of each second signal lamp 125 is electrically connected to the ground terminal of the power supply 122, and each electrical connector 123 is electrically connected to the power supply terminal of the power supply 122.

[0055] In this embodiment, each first contact 111, each second signal light 125, the power supply 122 and each electrical connector 123 are connected end to end in sequence to form a loop. When the electrical connector 123 moves to the second workstation, the electrical connector 123 is electrically connected to the second contact 112, and the entire loop is connected, which is convenient for detecting the second contact 112. The structure is simple and practical.

[0056] like Figure 2 As shown, the relay body 11 is further provided with a plurality of third contacts 113 , each of the third contacts 113 is arranged between the corresponding first contact 111 and the second contact 112 , and one end of each electrical connector 123 is electrically connected to one of the third contacts 113 .

[0057] In this embodiment, the third contact 113 usually corresponds one to one to the moving contact of the relay. When the electrical connector 123 moves to the first station, it drives the third contact 113 to be electrically connected to the first contact 111, thereby connecting the corresponding circuit; similarly, when the electrical connector 123 moves to the second station, it drives the third contact 113 to be electrically connected to the second contact 112, thereby connecting the corresponding circuit.

[0058] Specifically, the power supply 122 is a 5V to 10V DC power supply. The 5V to 10V DC power supply can meet the detection requirements, and the voltage is low, which will not cause electric shock injuries to personnel, nor will it burn equipment due to excessive voltage, thereby improving the safety of labor and equipment.

[0059] In some embodiments, Figure 1 As shown, the relay detection device 1 further includes: a lifting platform 13 , and the relay body 11 is arranged on the lifting platform 13 .

[0060] In this embodiment, the height of the relay body 11 is adjusted by setting the relay body 11 on the lifting platform 13 and adjusting the height of the lifting platform 13, thereby adjusting the operating height of the maintenance personnel, so that the maintenance personnel can operate the relay detection device 1 for detection in a more suitable posture, thereby reducing the work intensity of the maintenance personnel and reducing the risk of occupational diseases (cervical vertebrae diseases) for the maintenance personnel. The structure is simple and the use effect is good.

[0061] Specifically, the lifting platform 13 can be one of various lifting platforms such as a scissor-type lifting platform, a guide rail lifting platform, and a multi-column lifting platform.

[0062] In a specific embodiment, Figure 1 As shown, the relay detection device 1 includes a relay body 11 and a lifting platform 13; the lifting platform 13 is a scissor-type lifting platform with a height adjustment range of 80-340mm; the relay body 11 is a test box placed on the lifting platform 13; the relay detection device 1 can be placed on a desktop, and the lifting platform 13 can be adjusted according to the desktop and the height of the maintenance personnel to make the relay body 11 at a more comfortable operating height.

[0063] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, a plurality of relay sockets 115 are disposed on the relay body 11 , and each relay socket 115 is provided with a plurality of first contacts 111 and second contacts 112 corresponding to each other.

[0064] In this embodiment, by setting a plurality of relay sockets 115, the relay can be directly plugged into the relay detection device 1 through the relay socket 115, and the first contact 111 and the second contact 112 are directly electrically connected to the signal light, the power supply 122 and other components through the relay socket 115, without the need for separate connection, making the disassembly and assembly of the relay more convenient and quick, and improving the detection efficiency. By setting a plurality of relay sockets 115, the relay detection device 1 can be applied to the detection of multiple relays, which is easy to operate and has strong practicality.

[0065] Specifically, the number of contact groups of the first contacts 111 and the second contacts 112 on the plurality of relay sockets 115 may be different to be suitable for detecting relays with different numbers of contact groups, thereby making the device structure smaller and lighter while meeting various relay detection requirements.

[0066] In a specific embodiment, Figure 4 and Figure 5 As shown, the relay body 11 includes a 230×220×120mm test box, wherein a relay socket 115 with 8 groups of first contacts 111 and second contacts 112 is provided on the front side panel, which can be used for the detection of 8 groups of contact relays; the rear side panel is provided with a relay socket 115 with 4 groups of first contacts 111 and second contacts 112, which can be used for the detection of 4 groups of contact relays.

[0067] The device embodiments described above are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the present embodiment. A person skilled in the art may understand and implement the present invention without creative effort.
