Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery, specifically a crane emergency retraction device and a crane. Background Technology
[0002] Cranes, as important pieces of machinery, are widely used in engineering construction and production activities around the world. Wheeled cranes, in particular, are the most produced and widely used type of crane due to their high mobility and rapid relocation. In some Southeast Asian countries, such as Singapore, frequent thunderstorms mean that cranes often encounter such weather during operation. Some cranes have been struck by lightning, causing damage to electronic components, such as damaged printed circuit boards, damaged chips, and data errors, leading to control system failure and inoperability.
[0003] To mitigate the impact of lightning strikes, some manufacturers install surge protection modules on cranes to achieve surge discharge and suppress residual voltage spikes. However, this solution has strict requirements on the crane's body resistance and installation location, and cannot guarantee complete elimination of the impact of lightning strikes. After a crane is damaged by lightning, the safety of the work site cannot be guaranteed when the outriggers and boom are extended, and the crane's extended position makes it difficult to transport it to a repair shop for maintenance. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a crane emergency retraction device, including a display module, a communication harness, an operating module, and a control module.
[0005] The communication harness connects the control module and the crane control box, facilitating communication between them. The display module and control module are connected to the control module, which receives, processes, and outputs signals. The manipulation module is used for motion control and transmits the manipulation signals to the control module. The display module displays signals and is controlled by the control device.
[0006] When a crane becomes uncontrollable due to damage to its electronic components caused by lightning strikes or other reasons, a crane retraction device can be connected to the crane's control box via a communication harness. The control module in the retraction device can replace the crane's own control system to operate the crane and achieve the purpose of retraction in emergency situations.
[0007] Furthermore, it also includes a wireless communication module for wirelessly connecting the display module and the control module to the control module, and for communication between the display module, the control module and the control module, so that the operator can connect the control module to the crane's control box via a communication harness and operate it from a distance from the crane.
[0008] Furthermore, the control module includes one or any combination of a switch, joystick, knob, button, and touchpad.
[0009] Furthermore, the display module includes one or any combination of a display screen and a button panel with indicator lights.
[0010] Furthermore, the display module and the control module are the same touch screen, and the control and display are performed through the touch screen.
[0011] Furthermore, the control module, display module, and operation module are integrated into one unit.
[0012] Furthermore, the use of spring wires or the installation of winding spools in the communication harness can enable control over longer distances.
[0013] Furthermore, the control module includes a processor and a memory, the memory storing several control programs for cranes, and the corresponding control program is selected through the operation module.
[0014] Furthermore, it also includes an alarm module, which is set in the display module. When the control module detects that the output signal does not match the crane model, the alarm module issues a warning.
[0015] This utility model also provides a crane, which is equipped with the winding device described above.
[0016] This invention enables rapid reconnection and quick retraction of the crane when its electrical control system is damaged or malfunctions. Through wireless connection or operation over a longer distance, it ensures both safety and user-friendliness during retraction.
[0017] The emergency crane retraction device proposed in this utility model is characterized by its small size and simple components, making it easy to carry. It can meet the needs of various cranes, offering greater flexibility in use and satisfying market demand for spare parts. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1:
[0024] See Figure 1 , Figure 2 The emergency vehicle recovery device in this embodiment includes a display module 1, a communication harness 2, an operation module 3, and a control module 4. Through the communication harness 2, it can be quickly connected to the pre-installed connector on the crane control box 5.
[0025] Display module 1 is used to display crane detection signals and is equipped with a display screen. Control module 3 is used for motion control and consists of switches, control joysticks, etc. Furthermore, display module 1 and control module 4 can be integrated, with control achieved via virtual buttons on the touchscreen display. Control module 4 is used for signal reception, signal processing, and signal output. To facilitate remote crane control in case of failure, a wireless communication module is added between control module 4, display module 1, and control module, using wireless communication. Furthermore, a bus interface is reserved between control module 4, display module 1, and control module; if wireless communication is affected, direct connection to the bus can be used for communication.
[0026] The control module 3 includes physical or virtual control elements such as buttons, switches, knobs, keys, and touch panels. It can control the crane's boom extension, luffing, slewing, and hoisting movements, as well as control the crane's engine start and stop. Additionally, an emergency stop button can be installed to immediately halt operation. For single-cylinder pin-type telescopic boom cranes, the cylinder pin movement can be controlled independently, such as inserting or removing the cylinder pin or arm pin.
[0027] Display module 1 can display crane-related information detected by crane detection elements and processed by control module 4. It can display the input / output status of control module 4 ports and fault diagnosis information, and has operation guidance and alarm prompt functions, such as hoist overwind alarm and over-unwind alarm. For single-cylinder pin telescopic boom type models, it can display signals indicating cylinder pin, boom pin, boom position detection, etc.
[0028] It also includes developing safety control strategies, considering basic relevant safety controls, and, in the event of partial loss of detection signals, appropriately relaxing permissions within a safe range to control the crane's extension, winch, luffing, and slewing actions to achieve crane retraction operations.
[0029] By streamlining the ports for crane emergency retraction actions and signal acquisition, and connecting them to the quick connector 5 in the control box, the wiring harness connections for different crane models are standardized. Only one set of emergency retraction device is needed, and quick connection and use can be achieved without changing the wiring sequence.
[0030] The control module 4 includes a processor and a memory. Preferably, the memory stores several crane control programs for different crane models. Different control programs can be configured when the component's acquired and executed signals differ. The display module 1 allows selection for specific crane models. By inputting an advanced code, the recommended correct program can be switched, facilitating the availability of spare parts. Simultaneously, the control module 4 compares the acquired and output signals. If it determines that the control program is incompatible with the crane model, it will issue an alarm and impose action restrictions on the display via the alarm module, guiding the selection of the correct program and further ensuring operational safety.
[0031] To reduce costs, the display module 1 and the control module can be integrated; the display screen in the display module 1 can also be replaced by a button panel with indicator lights, and the control joystick or touch screen button in the control module can be replaced by physical buttons or keypads; in addition, the control module 4, display module 1 and control module 3 can be integrated into one unit, and the wiring harness connection between the module and the control box 5 can be in the form of spring wire or reel, etc., to achieve long-distance control.
[0032] The emergency retrieval device designed in this embodiment enables rapid connection and retrieval when the crane's electrical control system fails. It features a proprietary safety control strategy and operation guidance display module 1, ensuring both safety and user-friendliness during retrieval. The standardized wiring harness interface and configurable program across the series of vehicle models make the emergency retrieval device more flexible and meet market spare parts demands. The emergency retrieval device proposed in this invention is characterized by its small size and simple components, making it easy to carry in vehicles.
[0033] Example 2:
[0034] This embodiment is a crane equipped with a crane recovery device as described in the above embodiment, which can be carried on the crane or stored independently.
[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
