The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0022] The line cooling device applied to the riser cutting robot will be described below in combination with specific embodiments. Please refer to Figure 1 , Figure 1 is a structural schematic diagram of the line cooling device applied to the riser cutting robot provided by the embodiments of the application, wherein the riser cutting robot device 1; a gas pocket 2 is used as a gas source, at least one electromagnetic valve is connected, the gas inlet end of which is connected to the gas source, for controlling the on-off of compressed air; in this embodiment, two electromagnetic valves, namely electromagnetic valve 3 and electromagnetic valve 4, are connected; the electromagnetic valve 3 is connected to the flow meter 12, and the tail end is connected to the X1 motor line protection pipe 5, the Z motor line protection pipe 7, the C motor line protection pipe 8 and the Y motor line protection pipe 9; the electromagnetic valve 4 is connected to the flow meter 13, and the tail end is connected to the X2 motor line protection pipe 6, the A motor line protection pipe 10 and the B motor line protection pipe 11.
[0023] Among them, the line protection pipe is used for wrapping the cable of the riser cutting robot, the gas inlet end of which is connected to the gas outlet end of the electromagnetic valve, and the gas outlet end of the line protection pipe is provided with an exhaust port to form a cooling gas flow channel in the pipe,
[0024] In this embodiment, by placing the robot cable in the protection pipe and passing in the continuous flow of compressed air, active cooling protection of the cable in the high temperature environment is realized, and the failure caused by heat melting or burning of the cable is effectively avoided.
[0025] The control module is electrically connected with the electromagnetic valve and the main power supply of the riser cutting robot, for controlling the electromagnetic valve to be opened to pass in the compressed air when the device is powered on and running, and for controlling the electromagnetic valve to be closed to stop the air supply when the device is powered off.
[0026] In this embodiment, the control module is electrically connected with the main power supply or the main controller of the riser cutting robot, and the running state of the device is monitored in real time. When the riser cutting robot is powered on and starts or enters the running state, the control module automatically opens the electromagnetic valve, connects the compressed air, and starts to cool the cable; when the device is powered off, stops or triggers the emergency stop, the control module immediately closes the electromagnetic valve and cuts off the air source. It is ensured that the cooling is only enabled when it is really needed, the "on-demand cooling" is realized, and the waste of compressed air caused by continuous air supply when the device is not running is avoided.
[0027] Preferably, a flow monitoring module is arranged in the air path between the electromagnetic valve and the line protection pipe, and the flow monitoring module is in communication with the control module. When the flow is detected to be lower than a preset threshold, the control module sends a flow interruption alarm signal.
[0028] In this embodiment, the flow monitoring module is installed in the air path (e.g., after the electromagnetic valve outlet) to continuously detect the compressed air flow through the line protection pipe and determine whether the cooling system is working normally. When the air flow is interrupted or the flow is significantly reduced due to reasons such as pipe bending, seal aging, foreign matter blockage, or air source failure, the flow monitoring device (e.g., flow meter) can output an abnormal signal to trigger the control system to send an audible and visual alarm or a shutdown instruction, thereby avoiding the cable from being exposed to a high-temperature environment without cooling.
[0029] Further, a temperature sensor is arranged inside at least one line protection pipe or on the surface of the cable, and the signal output end of the temperature sensor is connected to the control module. The control module dynamically adjusts the opening degree of the electromagnetic valve or triggers a high-temperature alarm according to the signal of the temperature sensor.
[0030] By receiving the temperature data of the temperature sensor arranged in the cable or the protection pipe, when the temperature exceeds the threshold value: an over-temperature alarm is triggered; the opening degree of the electromagnetic valve can be further dynamically adjusted (if a proportional valve is used) to increase the cooling air flow; or the protection process is directly entered.
[0031] Further, the control module is further configured to: when receiving the flow interruption alarm signal of the flow monitoring module or the over-temperature alarm signal of the temperature sensor, automatically output a shutdown instruction to the control system of the riser cutting robot to stop the equipment running in linkage. In this embodiment, the temperature sensor and the flow sensor are linked to perform safety intervention. For example, the triggering conditions are that the flow continuously below the threshold value for more than a set time and the temperature rapidly rises or exceeds a dangerous value, and the alarm signal is not manually confirmed and processed. At this time, the action that can be performed is that the control module sends a shutdown instruction to the main controller (PLC / CNC) of the riser cutting robot; after the main system receives the instruction, the cutting operation is paused, the shaft movement is stopped, and the safety state is entered. Through the double early warning mechanism of this embodiment, it is prevented to continue running in the case of cooling failure, which leads to cable burning, short circuit, and even fire.
[0032] Preferably, the air outlet end of the line protection pipe is provided with a directional air outlet, and the air outlet direction of the air outlet is away from the movement components of the robot and the high-temperature area. The air outlet end of the line protection pipe is provided with a directional air outlet, and the air outlet direction of the air outlet is specially designed to make the compressed air flow discharged by the air outlet avoid the movement components (such as truss beams, slides, motor housings, drag chains, etc.) of the robot and the high-temperature heat source area (such as preheated castings, cutting gun operation points and their heat radiation range). If the compressed air is directly blown to the movement components (such as guide rails, encoders or sensors), it may cause excessive cooling, condensate accumulation or dust disturbance, affecting the positioning accuracy or causing false triggering. By directional air outlet, such interference can be avoided, and the stability of the robot movement can be ensured. If the air outlet is directed towards the high-temperature castings (surface temperature 200-300℃) or the cutting flame area (local temperature up to 1500℃), the low-temperature air flow discharged may be quickly heated and then backflow to the vicinity of the protection pipe outlet, weakening the cooling effect, and even forming a local thermal vortex. Directional air outlet can guide the waste heat flow to a low-temperature, open area, improving the cooling efficiency.
[0033] In the environment of a foundry workshop, if the air outlet has no direction control, it may form a negative pressure area at the outlet, sucking in the surrounding high-temperature sparks or metal dust, increasing the internal pollution of the pipeline or the risk of ignition. Directional air outlet can guide the air flow to a safe area (such as the floor below or a dedicated exhaust channel), reducing the safety hazards.
[0034] When multiple line protection pipes are discharging air at the same time, if the directions are chaotic, it is easy to cause local air flow disorder. By uniformly planning the air outlet direction (such as uniformly downward or towards the outside of the equipment), it is helpful to maintain the order of the air flow in the operation area and improve the working environment.
[0035] The technical features of the above-mentioned embodiments can be combined in any way. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described, but as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.
[0036] The above-mentioned embodiments only express several implementation ways of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, some modifications and improvements can be made, which are all within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
