Description

Technical Field

[0001] This application relates to the field of crane technology, and specifically to a device for identifying the jib of a crane and a crane. Background Technology

[0002] Wheeled cranes typically come with a jib, which is configured according to the customer's construction needs, resulting in a high degree of randomness. The jib parameters are closely related to the operation of the crane; incorrect installation or settings can easily lead to malfunctions, and in severe cases, pose safety risks. When using the jib in operation, the crane is often installed and set up manually, which is highly subjective, prone to errors, and makes it difficult to guarantee operational safety. Utility Model Content

[0003] This application provides a device and a crane for identifying the jib of a crane, in order to solve the problem in the related art that it is difficult to ensure the safety of operation when the lifting equipment is using the jib.

[0004] In a first aspect, this application provides a device for identifying a crane jib, comprising: The controller, located at the tail of the crane's jib, is used to read the jib parameters stored in the Controller Area Network (CAN) module and identify the jib based on these parameters. At least two CAN modules are installed on the jib of the crane. Each CAN module corresponds to one section of the jib of the crane and stores the jib parameters of the jib to which the CAN module is located.

[0005] In one alternative implementation, the connection line between at least two CAN modules extends from the boom head to the boom tail of the crane.

[0006] In one alternative implementation, the connection lines between at least two CAN modules are connected via a harness or interface of the secondary arm.

[0007] In one alternative implementation, the CAN module is fixed to the auxiliary arm at any of the following locations: the arm head, the arm middle, and the arm tail, via a protective bracket. In one alternative implementation, the device further includes a display screen for showing the installation status of each section of the crane's jib.

[0008] In one alternative implementation, the connection between each section of the crane's jib also includes a transfer frame connection.

[0010] In one alternative implementation, the controller is configured to read the secondary arm parameters stored in the CAN module connected to the connection line in response to the connection line; and identify the secondary arm based on the secondary arm parameters.

[0011] In one alternative implementation, the controller is also used to verify the auxiliary arm parameters.

[0013] The device for identifying the jib of a crane proposed in this application achieves the following beneficial technical effects compared to the prior art: The device includes a controller and at least two CAN modules. The controller is located at the tail of the jib of the crane and is used to read the jib parameters stored in the CAN modules and identify the jib based on the jib parameters, thus avoiding incorrect installation of the jib and eliminating potential safety hazards in later crane operations. The at least two CAN modules are installed on the jib of the crane, with each CAN module corresponding to one of the jib sections of the crane.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] It is understood that before using the technical solutions disclosed in the various embodiments of this application, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in this application in an appropriate manner in accordance with relevant laws and regulations, and user authorization should be obtained.

[0019] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0020] In related technologies, the length of the crane's jib is detected using a wireless beacon. However, due to the instability of wireless signals, it is difficult to guarantee the safety of the crane from installation to operation. The above-mentioned defects can be overcome by the following embodiments of this application.

[0021] The following is combined Figures 1 to 2 This describes an embodiment of the present application.

[0022] Figure 1 This is a structural diagram of a device for identifying a crane jib according to an embodiment of this application. Figure 1 As shown in one embodiment of this application, a device for identifying a crane jib is provided, the device comprising: The crane's jib, shown in this figure, has five sections: jib 101, jib 102, jib 103, jib 104, and jib 105. Adjacent jibs are connected by hinges.

[0023] At least two CAN modules are used; this diagram shows five CAN modules: CAN module 201, CAN module 202, CAN module 203, CAN module 204, and CAN module 205. Each section of the crane's jib is equipped with a CAN module, with each jib corresponding to a specific CAN module. Specifically, CAN module 201 is installed on the first jib section 101, CAN module 202 on the second jib section 102, CAN module 203 on the third jib section 103, CAN module 204 on the fourth jib section 104, and CAN module 205 on the fifth jib section 105. Leveraging the high-efficiency communication, strong anti-interference capabilities, industrial-grade reliability, and real-time data processing of the CAN modules, accurate parameters for each jib section can be obtained and provided to the controller, providing reliable data for identifying the jib's status.

[0024] Each CAN module stores the parameters of the secondary arm to which the current CAN module belongs.

[0025] The jib head 301 is the longest extendable part of the jib of the crane.

[0026] The jib tail 302 is the section that connects the jib to the main boom of the crane. The jib tail 302 connects the jib to the head of the main boom by means of hinge.

[0027] Controller 4, located at the tail of the jib of the crane, is used to read the jib parameters stored in the CAN module and identify the jib based on the jib parameters.

[0028] The adapter frame 5 is used to connect two adjacent jib sections. In some crane jib structures, the adapter frame 5 can be used to connect two adjacent jib sections to increase the uniformity of force distribution between them. In some crane jib structures, the adapter frame is not used, and each jib section is directly connected.

[0029] In this embodiment, a connection line between at least two CAN modules extends from the boom head 301 to the boom tail 302 of the crane. In one example, the connection line between CAN modules on adjacent boom sections can be a twisted-pair cable for twisted-pair communication. In another example, the connection line can also be a network cable for Ethernet communication. Since the connection line extends from the boom head 301 to the boom tail 302, if a single CAN module is considered as a node, then multiple nodes are formed sequentially connected by this connection line from the boom head 301 to the boom tail 302, where the number of nodes equals the number of boom sections.

[0030] In this embodiment, the connection lines between at least two CAN modules are connected via the wiring harness or interface of the secondary arm. In one example, the connection lines are deployed using the existing wiring harness on the secondary arm, saving the cost of separate wiring. In another example, the connection lines are connected using the existing interface on the secondary arm, which not only saves costs but also improves the stability of information transmission through the existing stabilization facilities.

[0031] In this embodiment, the CAN module is fixed to the auxiliary arm via a protective bracket at any of the following locations: the arm head, the arm middle, and the arm tail. Specifically, the protective bracket is used to fix the CAN module to the auxiliary arm. For ease of installation, the protective bracket is preferably positioned at the arm head, arm middle, or arm tail of the auxiliary arm to facilitate fixing the CAN module. In one example, the protective bracket can be pre-fixed to the arm head of the auxiliary arm by welding, and the CAN module can then be installed inside the protective bracket.

[0032] In this embodiment, the device for identifying the crane's jib further includes a display screen showing the installation status of each jib segment. In one example, after each jib segment is installed, the display screen automatically updates the jib segment corresponding to the current segment on the crane boom, providing feedback to the operator that the jib segment has been successfully installed. In another example, the display screen can also guide the operator in installing the crane's jib. When the operator completes the installation of a jib segment, the display screen, after updating the display to show successful installation of the current jib segment, prompts the operator to select a specified model of the next jib segment as the target jib for hinged installation with the current jib segment. This continuously provides the operator with reliable jib models, preventing errors in the installation sequence and avoiding safety threats during crane operations.

[0033] In this embodiment, the connection between each section of the crane's jib also includes a transfer frame connection. Due to the size and weight requirements of the objects to be lifted, the crane needs to support multiple extended jib sections. Between some adjacent jib sections, a transfer frame can be used to connect them to enhance the stability of adjacent jib sections.

[0034] In this embodiment, the parameters of each jib section of the crane include at least one of the following: host identification code, jib type, jib length, jib weight, and data write date. The host identification code is a unique identifier for the jib CAN module in the crane's CAN bus network, ensuring the controller can correctly and uniquely identify and read the information of the currently installed jib section. The jib type refers to the model or specification code of the specific jib currently installed at the top of the crane's main boom, such as a light-duty jib, heavy-duty jib, or luffing jib. The jib weight refers to the weight of the jib assembly. The data write date refers to the date on which the data (such as identification code, type, weight, etc.) inside the CAN module was last written to or modified.

[0035] In the embodiments of this application, the controller is used to respond to the access connection line by reading the auxiliary arm parameters stored in the CAN module connected to the connection line; and to identify the auxiliary arm based on the auxiliary arm parameters. Specifically, when a certain auxiliary arm section is installed, the CAN module corresponding to that auxiliary arm section is connected to the controller. The controller accesses the auxiliary arm parameters stored in the CAN module of each connected auxiliary arm section via the CAN bus. The controller can extract auxiliary arm feature data from the auxiliary arm parameters. Based on the auxiliary arm feature data, the auxiliary arm is identified to obtain information such as the length, weight, and configuration model of the current auxiliary arm. In one example, the identification of the auxiliary arm can be accomplished through a mapping table of auxiliary arm feature data and auxiliary arms. The configuration of all auxiliary arms generated by combinations of various auxiliary arm models and multiple auxiliary arm sections is pre-calibrated, and auxiliary arm feature data is extracted. During the step-by-step installation of auxiliary arms, for each auxiliary arm section installed, the controller can read the auxiliary arm data in the CAN module of the installed auxiliary arm and extract the auxiliary arm feature data, and obtain the auxiliary arm corresponding to the auxiliary arm feature data from the above mapping table. This auxiliary arm includes the model and installation order of each auxiliary arm section constituting the current auxiliary arm. In another example, different combinations of boom parameters can be collected as samples, and the corresponding boom segment of each sample can be used as a label. A large number of samples are collected and labeled accordingly. This large dataset and corresponding labels are used to train a deep neural network (such as a fully connected neural network or logistic regression) to obtain a boom recognition model. Based on the boom recognition model, the boom parameters are identified to obtain the overall boom composed of each currently installed boom segment. Furthermore, based on the boom segments and their corresponding working conditions, the working conditions of the boom are identified, and the current boom segment and its working condition are displayed on a screen. During installation, the operator confirms the installation request for each boom segment, thereby further improving the reliability of the installation and preventing installation errors. This enhances the safety of subsequent crane operations.

[0036] In the embodiments of this application, the controller is also used to verify the parameters of the auxiliary arm. Specifically, in order to quickly verify the connected CAN modules, the controller uses preset rules to verify the most recently connected CAN modules. For example, if the model of the currently installed auxiliary arm does not appear in the auxiliary arm model list of the controller or does not appear in the specified order, it will indicate that there may be an incorrect installation, alerting the operator to carefully check, thereby providing the operator with a means to verify the correctness of the installation.

[0037] Figure 2 This is a structural diagram of another device for identifying a crane jib according to an embodiment of this application. The device includes a jib head 301, a first jib section 101, ..., an Nth jib section, a first CAN module (CAN-1) 201, ..., an Nth CAN module (CAN-N), a jib tail 302, and a controller 4. Each jib section from the jib head 301 to the jib tail 302 is equipped with a CAN module, and each CAN module is sequentially connected via a twisted pair cable or a network. The CAN module is connected to the controller 4 at the jib tail 302. Through a segmented jib wiring design, and by adding CAN modules to each segment, the controller and the jib CAN are connected via a network. The jib parameters for each section are stored in the CAN module. By reading the jib parameters corresponding to the connected CAN modules, the controller can identify the jib and confirm the operation information or working condition. By adding a jib CAN bus identification function, the installed jib can be effectively identified, preventing incorrect installation. Furthermore, if a display screen is connected to the boom's controller, the identified boom can be shown through a human-machine interface, guiding the installation of the boom to be installed. Moreover, if an accident occurs due to operator error in installing the boom or selecting the wrong operating condition, the installation status of the boom can be effectively recorded, identifying incorrectly installed booms and providing sufficient evidence for subsequent accident handling.
