Description

Technical Field

[0001] The present invention relates to a strong-arm demolition vehicle, and in particular to an attachment identification device and an identification method for a strong-arm demolition vehicle. Background Art

[0002] In the field of engineering machinery safety control, strong-arm demolition vehicles are important equipment for emergency rescue. The frequent replacement and mode switching of their accessories has always been a key link in operational safety. Common accessory identification devices currently on the market mainly use electronic tag recognition or visual detection technology, such as obtaining accessory information through RFID readers or using cameras to capture accessory images for identification. Although such existing devices can automatically identify the type of accessory, they have obvious technical limitations: they can only determine the type or position of the accessory, but cannot detect whether the accessory is completely locked in place with the quick-change connector, nor can they identify whether the accessory has been incorrectly placed back into the bracket. The singleness of this detection dimension makes it impossible for the system to fully grasp the actual installation status of the accessory, so that the operator still needs to rely on visual observation to confirm the installation status after replacing the accessory. In a complex working environment, it is very easy to make misjudgments due to visual errors or operational negligence. At the same time, existing devices generally lack effective safety interlock mechanisms. When an attachment is installed and the mode does not match, the system can only provide passive prompts such as audible and visual alarms, but cannot actively intervene in the device's operation. This can lead to the device continuing to perform incorrect operations if the operator fails to respond in time after the alarm is issued, resulting in serious consequences such as attachment detachment, equipment damage, and even casualties. These technical defects not only reduce operational efficiency but also pose a major safety hazard to emergency rescue work. Summary of the Invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a strong-arm demolition vehicle attachment identification device that can eliminate manual judgment errors and is safe and reliable. Another purpose of the present invention is to provide a method for identifying strong-arm demolition vehicle attachments using the device.

[0004] Technical solution: The strong-arm demolition vehicle accessory identification device of the present invention includes a locking detection unit, an accessory storage detection unit, a control module, and an execution module; the locking detection unit is arranged inside the arm head quick-change connector, and is used to output an accessory locking status signal; the accessory storage detection unit outputs an accessory storage status signal; the control module is electrically connected to the locking detection unit, the accessory storage detection unit and the execution module respectively, and the control module outputs an operation permission instruction when receiving an accessory locked signal and a corresponding accessory not stored signal; the control module outputs an operation prohibition instruction when receiving an accessory not locked signal or a corresponding accessory stored signal; the execution module connects or disconnects the power circuit of the demolition vehicle operating mechanism according to the control module instruction.

[0020] Preferably, the alarm in steps S3 and S4 includes generating a high-frequency warning sound, generating vibration feedback on the control handle, and highlighting the cause of the abnormality on the status display unit.

[0021] Preferably, the system further includes a self-test step: detecting the communication status of each detector in turn when the system is powered on; simulating and generating a test signal to verify the control logic; outputting a self-test report and marking the faulty component.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1-8As shown, the core structure of the strong-arm demolition vehicle attachment identification device in this embodiment includes a lock detection unit, an attachment storage detection unit, a control module, and an execution module. The lock detection unit is located within the boom head quick-change connector and outputs an attachment lock status signal. The attachment storage detection unit outputs an attachment storage status signal. The control module is electrically connected to the lock detection unit, the attachment storage detection unit, and the execution module. The control module serves as the decision-making center of the entire device, receiving signals from the lock detection unit and the attachment storage detection unit, making judgments, and then generating corresponding action command signals to the execution module, which then executes the corresponding actions. When the lock detection unit detects that the attachment is unlocked, it means that the attachment is not in place, and the control module prohibits the execution of the module action to prevent the attachment from falling and causing a safety accident. When the lock detection unit detects that the attachment is locked, the attachment storage detection unit detects whether the corresponding attachment is in place. If the corresponding attachment is also detected to be in place, it indicates that the mode selection is incorrect and the locked attachment does not match the selected attachment mode. The control module prohibits the execution of the module action to avoid the operator's incorrect operation due to the different action logic and restriction protection corresponding to different attachments, resulting in low work efficiency and even safety accidents, causing damage to equipment and operators. When the lock detection unit detects that the attachment is locked and the attachment storage detection unit detects that the corresponding attachment is out of place, it indicates that the mode matching is normal, and the control module allows the execution of the module action. After the control module prohibits the device from continuing to operate, the operator can manually trigger the emergency unlock switch to force the power circuit to open after checking and correcting the problem. After the control module processes the new signal data and gives the permission instruction, normal operation can continue. This dual detection device, namely the locking detection unit and the accessory storage detection unit, is linked with the control module to eliminate manual judgment errors and improve the safety and efficiency of operations.

[0031] Furthermore, if the control module detects that an attachment is not properly installed or the incorrect mode is selected, the actuator module's alarm unit and hydraulic control valve group will also begin operating simultaneously. The alarm unit generates a high-frequency warning tone, the control handle produces vibration feedback, the status display unit highlights the cause of the abnormality, and the hydraulic control valve group shuts off the operating oil circuit, prohibiting further operation. The status display unit allows the operator to view the attachment lock status, attachment storage status, currently selected attachment mode, and system fault codes in real time. Upon system startup, the system automatically runs a self-test program, sequentially verifying each sensor signal path, simulating lock and storage signals to verify the control logic, and ultimately generating a self-test report and flagging faulty components to ensure device reliability.

[0032] The lock detection unit, embedded within the boom head quick-change connector, consists of a lock 1 for securing the attachment and a first detector 2 that detects the mechanical displacement of the lock 1 and converts it into a lock status signal. The core of the lock 1 is an axially movable locking pin 5 with an annular boss 6 at its center. A return spring 7 pushes the locking pin 5 to its extended position, securing the attachment. The first detector 2 uses a non-contact sensor aligned with the movement path of the annular boss 6. When the attachment is locked, the locking pin 5 retracts under external force, triggering the annular boss 6 to trigger the first detector 2 to emit a "locked" signal. Conversely, if the locking pin 5 is not in place, the first detector 2 outputs an "unlocked" signal. The attachment storage detection unit consists of a telescopic member 3 and a matching second detector 4. The telescopic member 3 contains a probe and a spring. The probe is held in an extended position by the spring. When the attachment is stored in the vehicle bracket, the probe is pressed in, triggering an "in position" signal. When the attachment is removed, the probe is ejected and a "out of position" signal is fed back.

[0033] The device's identification process works as follows: After the operator selects an attachment mode via the control panel, the system collects locking and storage signals in real time. It first verifies the locking status. If locking fails, an alarm is triggered. If locking succeeds, the system then compares the attachment storage status with the selected mode to ensure a logical match. If a discrepancy is detected, the system deems it an error, triggers an alarm, and prohibits the vehicle from starting.

[0034] Through the coordinated verification of dual physical signals of the locking detection unit and the attachment storage detection unit, and combined with the real-time logical judgment of the control module and the rapid response mechanism of the execution module, a complete attachment identification system is formed, which realizes the intelligent matching and active protection of the attachment installation status and operation mode. It not only improves the safety and reliability of the strong-arm demolition vehicle operation, but also solves the risk of misoperation of the existing device, and significantly improves the safety protection level of the strong-arm demolition vehicle under complex working conditions.
