Description

Technical Field

[0001] The present application relates to the technical field of reducers, and in particular to a reducer monitoring device and a reducer working system. Background Art

[0002] At present, the reducer is an important component of engineering machinery. Its application conditions are harsh, which will have a significant impact on the overall working performance, operation safety, and service life of engineering machinery. At present, during the use of reducers, major reducer manufacturers at home and abroad generally pay little attention to their internal operating environment, and usually do not effectively grasp the temperature rise and leakage of the internal gear oil of the reducer under actual working conditions. Very few companies will install a temperature sensor inside their reducer to transmit the oil temperature value inside the reducer to the controller. Only installing a temperature sensor can only detect the gear oil temperature inside the reducer, but cannot detect the oil pressure. Therefore, the floating oil seal is damaged, causing the internal gear oil to leak, and it cannot be monitored and processed in time. The result is that hidden faults occur inside the reducer (for example: gear pitting, wear, fracture, etc., resulting in oil temperature rise and floating oil seal damage and oil leakage), but the operator is not aware of it. He continues to operate the engineering machinery under hidden dangers, which eventually leads to major faults of the reducer until the entire engineering machinery stops. Summary of the invention

[0032] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0033] The components of the embodiments of the present application generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed, but merely represents the selected embodiments of the present application.

[0034] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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 this application can be understood according to specific circumstances.

[0037] Refer to the following Figures 1 to 3The invention describes a reducer monitoring device and a reducer working system according to some embodiments of the present application.

[0038] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a reducer monitoring device, including: a temperature and pressure sensor 1, which is used to be connected to the gear oil filling port 901 of the reducer 9 to detect the oil temperature and oil pressure inside the reducer 9.

[0039] The reducer monitoring device provided in this embodiment senses the oil temperature and oil pressure inside the reducer 9 through the temperature and pressure sensor 1 it has, so that the user can monitor the temperature rise of the gear oil inside the reducer 9 and whether there is oil leakage inside the reducer 9, thereby ensuring the normal operation of the reducer 9, which is safer and more reliable.

[0040] In addition, according to the temperature and pressure sensor 1 provided in the embodiment, it is directly and detachably connected to the gear oil filling port 901 of the reducer 9, without the need for cable connection, and has a wider range of applications. It can be particularly used in the following situations, that is, the reducer 9 encounters special working conditions, because its shell rotates (such as the walking reducer 9), or it runs in the air (such as the power head reducer 9, the mast lifting reducer 9, etc.). Ordinary sensors with cables cannot be connected to the controller through conventional cable connection methods. Therefore, the monitoring of important indicators is basically abandoned on these models of reducers 9. The temperature and pressure sensor 1 of the present application can cope with this situation without being restricted by cables.

[0041] In this embodiment, if Figure 2 As shown, the temperature and pressure sensor 1 and the gear oil filling port 901 of the reducer 9 are detachably connected by threads, that is, the gear oil filling port 901 is provided with channels running through both ends thereof, one end of the channel is connected to the outside of the reducer 9, and the other end of the channel is connected to the inside of the reducer 9, and an internal thread is processed on the inner wall of the channel. The temperature and pressure sensor 1 has a connecting end 101, and the outside of the connecting end 101 is processed with an external thread, so that the connecting end 101 is screwed into the channel of the gear oil filling port 901, thereby realizing a detachable connection between the temperature and pressure sensor and the gear oil filling port 901, so as to detect the temperature and oil pressure inside the reducer 9.

[0042] Of course, this is not limited to this. Although not shown in the figure, the temperature and pressure sensor can also be plugged into or sleeved with the gear oil filling port, and a sealing gasket can be set between the two. For example, when the temperature and pressure sensor is plugged into the gear oil filling port, the gear oil filling port is provided with a channel running through both ends thereof, one end of the channel is connected to the outside of the reducer, and the other end of the channel is connected to the inside of the reducer. The temperature and pressure sensor has a connecting end, which can be inserted into the channel, and an O-ring is set between the two to prevent oil leakage.

[0043] Among them, optionally, in the embodiment, the temperature and pressure sensor 1 is an integrated wireless temperature and pressure sensor, which can sense both temperature and pressure, and has the connection terminal 101 described above. The integrated temperature and pressure sensor is a commonly used sensing element in the prior art, and its other structures are not described in detail here.

[0044] In this embodiment, if Figure 2 and Figure 3 As shown, the reducer monitoring device further includes a data processing module 2 and a transmission terminal 3 electrically connected to each other;

[0045] The data processing module 2 is electrically connected to the temperature and pressure sensor 1; the transmission terminal 3 is wirelessly connected to the user client 4 via the mobile communication network 7;

[0046] The data processing module 2 is used to collect the data of the oil temperature and oil pressure in the reducer 9 in real time, and actively upload the data to the transmission terminal 3 at a regular time; or

[0047] The data processing module 2 is used for sending the temperature and pressure data to the transmission terminal 3 when receiving the instruction from the transmission terminal 3 to obtain the oil temperature and oil pressure data;

[0048] Among them, the data processing module 2 includes a control unit 201, an A / D conversion unit 202 (i.e., an analog-to-digital conversion unit) and a storage unit; the temperature and pressure sensor 1, the A / D conversion unit 202, the storage unit and the transmission terminal 3 are electrically connected in sequence; the temperature and pressure sensor 1, the A / D conversion unit 202 and the storage unit are electrically connected to the control unit 201 respectively.

[0049] According to the structural setting described above, when the reducer monitoring device of this embodiment is working, the temperature and pressure sensor 1 can automatically collect the oil temperature and oil pressure inside the reducer 9 as needed, and perform A / D conversion. The converted temperature and pressure values ​​are stored in the storage unit. The data is sent to the transmission terminal 3 on the engineering machinery host through the 2.4G ZigBee wireless communication protocol 8 through active uploading (temporary sending of temperature and pressure data) or passive acquisition (when the transmission terminal 3 on the engineering machinery host sends an acquisition instruction, the temperature and pressure values ​​are sent. This design mode is an energy-saving mode. When the host's acquisition instruction is not received, the main control unit 201 is in a dormant state).

[0050] Then, the transmission terminal 3 packages the collected data, and through the built-in HUAWEIME909s-821 module on the transmission terminal 3, the packaged data message can be conveniently transmitted to the network server of the host manufacturer through the mobile communication network 7 such as the 4G public network. The server then uses the Internet of Things communication protocol MQTT to send the data or alarm information to the operator's user client 4, such as the portable mobile client 401 and the cloud monitoring terminal 402, where the portable mobile client can be a mobile phone client, that is, a mobile phone APP, of course, not limited to this.

[0051] On this basis, that is, after having enough collected data resources as big data support, AI intelligent comparative analysis can be performed on the operating status of online devices, the operating status of the equipment can be diagnosed, and early fault warning function reminders can be made. That is, the mobile phone APP or cloud monitoring terminal 402 can remotely set and modify the temperature and pressure alarm thresholds of the intelligent reducer 9 through the network. When the warning signal is generated, the passive acquisition mode will automatically switch to the active upload mode, and an alarm prompt will be issued until the host confirms the alarm and returns to the passive acquisition mode.

[0052] Among them, the transmission terminal 3 can be a host instrument, which includes a main control unit 301, a communication module 302 and a touch screen 303, etc. The communication module 302 is used to receive and send data, the main control unit 301 is used to manage the communication module 302, and the touch screen 303 is used to send instructions to the main control unit 301. Of course, it is not limited to this.

[0053] In this embodiment, if Figure 2 and Figure 3 As shown, the reducer monitoring device also includes a nickel-hydrogen battery charge and discharge management unit 6 and a nickel-hydrogen battery 5 which are electrically connected to each other;

[0054] The nickel-hydrogen battery charge and discharge management unit 6 and the nickel-hydrogen battery 5 are electrically connected to the control unit 201 respectively;

[0055] The nickel-hydrogen battery 5 is electrically connected to the temperature and pressure sensor 1 for supplying power to the temperature and pressure sensor 1;

[0056] When the data processing module 2 sends the oil temperature and oil pressure data to the transmission terminal 3 at a regular time, the control unit 201 controls the nickel-hydrogen battery 5 to be in the energy-saving mode under the first power consumption;

[0057] When the data processing module 2 does not receive the instruction from the transmission terminal 3 to obtain the data of the oil temperature and the oil pressure, the control unit 201 controls the nickel-hydrogen battery 5 to be in the energy-saving mode under the second power consumption.

[0058] According to the structural setting described above, the temperature sensing component as the integrated temperature and pressure sensor as described above has a built-in nickel-hydrogen battery charge and discharge management unit 6 and a nickel-hydrogen battery 5, such as a 360ma nickel-hydrogen battery. In the active upload mode mentioned above, the control unit 201 makes the nickel-hydrogen battery 5 in an energy-saving mode under the first power consumption, specifically, the power consumption is as low as 5mA / h, and the working time can reach 80 hours. In the passive acquisition mode mentioned above, the control unit 201 makes the nickel-hydrogen battery 5 in an energy-saving mode under the second power consumption, specifically, the power consumption is as low as 0.5mA / h, and the working time can reach 800 hours. While monitoring the temperature and oil pressure, energy-saving use of the battery can be achieved. Among them, the control unit 201 can obtain the charge and discharge signal from the nickel-hydrogen battery charge and discharge management unit 6.

[0059] In summary, the reducer monitoring device provided in this embodiment uses an integrated temperature and pressure sensor to simultaneously detect the oil temperature and oil pressure inside the reducer 9, which makes the monitoring of the key indicators of the reducer 9 more complete and saves installation space and cost. The integrated temperature and pressure sensor is powered by a nickel-hydrogen battery 5 and does not require a cable, so it can be installed on any reducer 9. The integrated temperature and pressure sensor adds a data processing module 2 and a control module, etc., to achieve intelligent monitoring and information feedback of the reducer 9. Among them, a 2.4G wireless communication protocol is used between the integrated temperature and pressure sensor and the transmission terminal 3. Because there is no cable, the rotation and movement of the reducer 9 do not affect the transmission of the signal. At the same time, the monitoring indicators of the reducer 9 can be sent to the operator's mobile phone APP and the cloud monitoring center to achieve early warning and big data statistics.

[0060] An embodiment of the present application also provides a reducer working system, including the reducer monitoring device described in any of the above embodiments, and thus has all the beneficial technical effects of the device, which will not be repeated here.

[0061] In this embodiment, the reducer working system also includes a reducer 9, which is connected to the temperature and pressure sensing component of the reducer monitoring device. Specifically, the connecting end 101 of the temperature and pressure sensor 1 is connected to the gear oil filling port 901 of the reducer 9. It can be seen that the temperature and oil pressure inside the reducer 9 are sensed by the temperature and pressure sensor 1 of the reducer monitoring device, so that the user can monitor the temperature rise of the gear oil inside the reducer 9 and whether there is oil leakage inside the reducer 9, so as to ensure the normal operation of the reducer 9, which is safer and more reliable.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
