Description

Technical Field

[0001] This utility model relates to the field of engineering machinery manufacturing technology, and in particular to an excavator travel reducer installation system. Background Technology

[0002] As a crucial piece of construction equipment, the performance and reliability of the excavator's travel system play a key role in the overall operating efficiency and safety. The travel reducer, as a core component of the travel system, directly affects the excavator's operational stability and service life through its installation quality. With the diversification of excavator market demands, companies need to produce various models to meet different customer needs, making frequent model changes the norm.

[0003] During the chassis assembly process, the required angle of the reducer towards the center joint varies depending on the model. Due to frequent model changes, operators in high-intensity, fast-paced production environments often struggle to accurately remember the installation angle for each reducer model, easily leading to incorrect installation. Incorrect reducer installation not only causes malfunctions and abnormal wear in the travel system but can also trigger serious quality issues, increasing after-sales maintenance costs. Currently, traditional reducer installation methods rely heavily on operator experience and memory, lacking effective error-prevention mechanisms. While some companies have developed installation guidelines, in practice, operator negligence and fatigue make strict adherence to these guidelines difficult, resulting in frequent installation errors.

Attached Figure Description

[0032] Figure 1 This is a schematic diagram showing the structure of the excavator travel reducer installation system provided in this embodiment of the utility model. Detailed Implementation

[0033] To make the technical problems, technical solutions, and advantages of this utility model clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this utility model. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this utility model. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0034] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0035] Reference Figure 1As shown in the figure, this application provides an excavator travel reducer installation system, including:

[0036] First memory 1, used to store excavator production plans;

[0037] The second memory 2, connected to the first memory 1, is used to obtain the excavator production plan and obtain the machine type information of the excavator currently in operation based on the excavator production plan;

[0038] The third memory 3 is used to pre-store the speed reducer installation angle parameters corresponding to various machine types;

[0039] Controller 4 is connected to the second memory 2 and the third memory 3 respectively;

[0040] At least one speed reducer installation control line is connected to the controller 4; each speed reducer installation control line is equipped with at least one first relay 5.

[0041] In this embodiment, the system, through the coordinated operation of various memories, controllers, and control circuits, achieves automated machine type identification, angle positioning, and error prevention warnings during the installation process of the excavator travel reducer, effectively solving many problems associated with manual installation. Specifically, the first memory 1 pre-stores the excavator production plan, which includes key information such as production task arrangements and machine type for different excavator models. The second memory 2 is connected to the first memory 1 and actively acquires the excavator production plan, providing a data foundation for subsequent operations. Based on the acquired excavator production plan, the second memory 2 parses out the machine type information of the excavator currently requiring operation. This machine type information may include characteristic parameters used to distinguish different machine models, such as the excavator's model, specifications, and applicable working conditions. For example, if the current task in the production plan is to produce a certain model of 20-ton excavator, the second memory 2 will extract the machine type identification information corresponding to that model. The third memory 3 pre-stores the reducer installation angle parameters corresponding to various machine type information. These parameters are standard installation angle values ​​pre-set according to the design requirements and performance indicators of different machine types. The controller 4 is connected to the second memory 2 and the third memory 3. When the second memory 2 obtains the current machine type information, the controller 4 will retrieve the reducer installation angle parameter that matches the machine type information from the third memory 3. For example, if the current machine type is model A excavator, the third memory 3 will have a parameter record of the installation angle α° corresponding to model A, and the controller 4 will retrieve that angle parameter.

[0042] The controller 4 generates a corresponding control signal based on the acquired installation angle parameters. The controller 4 transmits the control signal through at least one connected reducer installation control line. Each control line is equipped with at least one first relay 5, which acts as an electronic switch to receive and execute commands from the controller. The control signal is transmitted to the first relay 5 through the control line, controlling the relay's on / off state, and thus controlling the movement of the installation equipment (such as a robotic arm, positioning device, etc.) connected to the relay, to achieve precise control of the reducer's installation angle.

[0043] During installation, controller 4 monitors in real time whether the installation angle matches the standard angle parameters retrieved from the third memory 3. If the angle deviation exceeds a preset threshold during installation, controller 4 will trigger an error prevention warning function, possibly through light alarms, sound prompts, or sending alarm information to the system backend, to remind the operator to make timely adjustments and avoid installation quality problems caused by angle errors. For example, when the actual installation angle deviates from the standard angle α° by more than ±β°, controller 4 immediately activates an early warning to prevent the incorrect installation from continuing.

[0044] This application achieves accurate acquisition of current machine type information without manual intervention through data interaction between memory locations, improving identification efficiency and accuracy. Utilizing pre-stored standard angle parameters and precise controller control of the installation equipment, it achieves accurate positioning of the reducer installation angle, significantly reducing the angle error rate. Real-time monitoring of the installation process and timely warnings in case of deviations effectively avoid quality risks caused by negligence or operational errors during manual installation, improving installation quality and production efficiency.

[0045] Optionally, the core actuator on the reducer's control circuit is the first relay 5, which is as follows: Figure 1The diagram shows KM1, KM2, KM3, and KM4. The first relay 5 acts as an electrical control switch, receiving electrical signals from the controller 4 and controlling the circuit's on / off state, thereby driving the installed actuators (such as hydraulic valves, motors, etc.) to operate. The first relay 5 is typically an electromagnetic relay or a solid-state relay, possessing high reliability and fast response capabilities, suitable for frequent operation requirements in industrial environments. The first relay 5 is connected in series in the control circuit, with its coil end connected to the output of the controller 4 and its contact end connected to the installed actuator circuit. The reducer installation control circuit may also include: fuses / circuit breakers to prevent damage to relays and other components in case of overload or short circuit, usually connected in series at the control circuit power supply end; surge protectors to suppress transient overvoltages in the circuit, protecting relays and controllers from electromagnetic interference, especially suitable for high-frequency operation scenarios; and signal transmission cables, often using shielded cables or twisted-pair cables to reduce the impact of electromagnetic interference on control signals and ensure the accuracy of command transmission. Here, the coil end of the first relay 5 in the control circuit is connected to the output of the controller 4, and the contact end is connected to the installed actuator, such as a hydraulic motor or servo motor. The installation actuator can be used to drive a robotic arm or to move a speed reducer while installing tooling.

[0046] Optionally, the first relay 5 of each of the aforementioned reducer mounting lines is connected to a refueling line, the refueling line comprising:

[0047] Solenoid valve 6, air pump 7, and flow meter 8;

[0048] The solenoid valve 6 is connected to the first relay 5;

[0049] The air pump 7 is connected to the solenoid valve 6 and the flow meter 8 respectively.

[0050] In this application, the first relay 5 of each of the aforementioned reducer installation lines is connected to a filling line, such as... Figure 1 KM1, KM2, KM3, and KM4 are connected to the filling lines. The solenoid valve 6 acts as the electrical control switch for the filling line, with its coil connected to the contact of the first relay 5 to receive the relay's on / off signal. The air pump 7 provides the filling power; its input is connected to the outlet of the solenoid valve 6, and its output is connected to the flow meter 8. This is typically a pneumatic diaphragm pump or an electric air pump, adaptable to the viscosity requirements of the lubricating oil / hydraulic oil. The flow meter 8 is connected in series at the end of the filling line to monitor the oil flow rate in real time, and the signal is output to the controller 4 to control the accuracy of the filling volume.

[0051] When the controller 4 drives the first relay 5 to engage, the contacts simultaneously connect the installation actuator circuit and the solenoid valve 6 coil circuit, achieving "automatic triggering of lubrication upon completion of installation and positioning." For example, after the reducer installation angle meets the standard, the first relay 5 engages, the installation robotic arm stops moving, and simultaneously the solenoid valve 6 opens and the air pump 7 starts, beginning the addition of lubricating oil to the reducer. Closed-loop control of the lubrication amount: Flowmeter signal feedback: The flowmeter 8 converts real-time flow data (e.g., L / min) into an electrical signal (e.g., 4-20mA) and transmits it to the controller 4. Controller logic processing: The controller 4 compares the real-time cumulative flow with pre-stored lubrication parameters for different reducer models (e.g., a certain model requires 3.5L). When the cumulative flow reaches 90% of the preset value, the controller 4 outputs a PWM signal to adjust the opening of the solenoid valve 6, reducing the flow of the air pump 7 to achieve a "fast first, slow later" lubrication rhythm; when the flow reaches the preset value ±0.1L, the controller 4 cuts off the signal from the first relay 5, the solenoid valve 6 closes, the air pump 7 stops, and the lubrication is complete. This application avoids the problems of forgetting to add fuel or inaccurate fuel volume after manual installation, and reduces the manual intervention steps in installation and fueling.

[0052] Optionally, the system further includes:

[0053] The second relay 9 is connected to the controller 4;

[0054] The laser positioning module 10 is connected to the second relay 9; the laser positioning module 10 is used to emit a positioning laser point to indicate the standard installation position.

[0055] In this embodiment, the second relay 9 is referenced. Figure 1 KM5 and KM6 in the diagram, each of the second relays 9 is connected to the controller 4 and a laser positioning module 10, respectively. The second relay 9 acts as an electrical control switch for the laser positioning module; its coil end is connected to the output of the controller 4, and its contact end is connected to the power supply circuit of the laser positioning module 10. The laser positioning module 10 is typically a semiconductor laser emitter, such as red light with a wavelength of 635-670nm or green light with a wavelength of 520nm. The emission and deactivation of the laser point are controlled by the on / off state of the second relay 9, used to visually indicate the standard installation position of the reducer.

[0056] This application integrates the second relay 9 with the laser positioning module 10 to construct a composite positioning system of "digital parameter control plus physical vision guidance". This system not only meets the high-precision installation requirements of automated production lines, but also provides an intuitive auxiliary tool for manual operation. Especially in multi-model mixed production scenarios, the positioning reference can be quickly adapted through parameter switching, further improving the system's flexibility and installation efficiency.

[0057] Optionally, the system further includes:

[0058] An angle sensor 11 is installed on the reducer and is used to detect the actual installation angle of the reducer toward the center joint in real time.

[0059] The data acquisition module 12 is connected to the angle sensor 11 and the controller 4, and is used to transmit the installation angle signal corresponding to the actual installation angle to the controller 4.

[0060] In this embodiment, the angle sensor 11 is typically an absolute encoder or tilt sensor, directly mounted on the reducer housing or output shaft to monitor the actual angle of the reducer relative to the center joint in real time. The data acquisition module 12 acts as a signal conversion hub, converting the analog or digital signals output by the angle sensor 11 into a standard protocol recognizable by the controller 4.

[0061] Here, the angle sensor and the data acquisition module form a closed-loop feedback system, enabling the controller 4 to compare the actual angle with the standard angle parameters (third memory 3) in real time; dynamically adjust the on / off logic of the first relay 5 to precisely control the installation actuator; and trigger an early warning or automatic correction when the angle deviation exceeds the limit to achieve error prevention function.

[0062] Optionally, the controller 4 includes:

[0063] Comparator 41 is connected to the third memory 3 and the data acquisition module 12 respectively, and is used to compare the first signal of the reducer installation angle parameter corresponding to the current model information with the corresponding installation angle signal. When the voltage corresponding to the installation angle signal is greater than the voltage corresponding to the first signal, the first comparison signal is output.

[0064] The first signal output device 42 is connected to the comparator 42 and at least one of the first relays 5, and is used to receive the first comparison signal and output a cut-off control signal to the first relay 5 corresponding to the current model information.

[0065] In this embodiment, the voltage comparison chip integrated into the comparator 41 directly connects to the standard angle parameter signal and the actual angle feedback signal to achieve real-time analog quantity comparison. The first signal output device 42 can be composed of a transistor or MOSFET driving circuit, which controls the on / off state of the relay coil according to the logic level output by the comparator. Through the above hardware circuit design, the controller 4 realizes the real-time comparison and relay control functions of pure analog quantities. It can complete the angle deviation judgment and cut-off control without relying on software algorithms, and the response speed can reach the microsecond level, meeting the high reliability and anti-interference requirements of industrial sites. It is especially suitable for automated installation scenarios with strict real-time requirements.

[0066] Optionally, the system further includes:

[0067] First display 13;

[0068] The second signal output device 14 is connected to the comparator 41 and the first display 13. The second signal output device 14 is used to receive the first comparison signal and output an alarm signal to the first display 13.

[0069] In this embodiment, the second signal output device 14, based on the isolation drive circuit of the optocoupler, converts the high-level signal of the comparator into an alarm trigger signal recognizable by the display. The first display 13 is typically a three-color LED indicator (red / yellow / green) or an LCD screen, used to visually display the installation status.

[0070] Optionally, the system further includes:

[0071] The second display 15 is connected to the second memory 2 and the third memory 3 respectively.

[0072] In this embodiment, the second display 15 may be equipped with a data selector, which uses a 74HC157 quad 2-to-1 multiplexer to switch the display data source via the chip select signal (CS) of the controller 4. The second memory 2 transmits the model code via the SPI bus (MOSI / MISO / SCK); the third memory 3 transmits the model code via I... 2 C-bus (SDA / SCL) transmits angle parameters.

[0073] Optionally, the first display 13 and the second display 15 share a +5V regulated power supply, with a self-resetting fuse connected in series at the input terminal. When the current exceeds 200mA, it will automatically disconnect to prevent short circuit damage to the display module.

[0074] Optionally, the controller 4 described above can be connected to a separate power supply, or it can share a power supply with the first display 13 and the second display 15.

[0075] Through the above hardware circuit design, the system realizes a dual human-machine interaction mechanism of "real-time display of angle deviation plus over-limit alarm triggering". Operators can quickly judge the installation status through the indicator light color of the first display 13, and at the same time obtain accurate parameter comparison data through the second display 15, which greatly improves the operation efficiency and installation quality.

[0076] In summary, the proposed solution saves money by changing the filling operation from a single person to an automated operation; the improved structure diagram avoids personnel maintenance costs caused by insufficient gear oil filling and incorrect gear angle.
