Description

Technical Field

[0001] This utility model relates to the technical field of aluminum electrolysis production equipment, specifically to a material tube anti-collision detection device for an aluminum electrolysis overhead crane shell-breaking machine. Background Technology

[0002] In the aluminum electrolysis production process, the overhead crane shell-breaking machine plays a crucial role. However, during operation, the relative movement between the shell-breaking head and the material tube of a traditional shell-breaking machine often poses a collision risk due to operational errors or equipment malfunctions, which can damage the equipment and threaten production safety. To address this challenge, technicians have made numerous attempts, such as the anti-collision buffer mechanism for the loading and unloading robot disclosed in Chinese patent CN205465411U. Although it includes pneumatic fingers and grippers, it still has shortcomings: First, it lacks a real-time monitoring mechanism, making it difficult to detect the proximity of the shell-breaking head to the moving tube in a timely manner, increasing the risk of collision; second, the position adjustment method is not flexible enough, relying on manual or low-precision adjustment methods, making it difficult to achieve rapid and accurate adjustment of the moving tube position, thus affecting the operating efficiency and overall safety of the equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a material tube anti-collision detection device for an aluminum electrolysis overhead crane shell-breaking machine.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A collision prevention detection device for the feed pipe of an aluminum electrolysis overhead crane shell-breaking machine includes a shell-breaking machine, a support base located on the side of the shell-breaking machine, a feeding channel located on the support base, and an adjustment mechanism, wherein:

[0006] The shell-breaking machine includes a cylinder at the top and a shell-breaking head connected to the cylinder. The shell-breaking head extends and retracts under the drive of the cylinder, and the shell-breaking head is positioned facing the electrolytic cell below.

[0007] The support base includes a clamping part that clamps on both sides of the shell of the shell-breaking head. A main support is provided along one side of the clamping part, and an L-shaped side support is provided below the main support. The main support and the side support together support the inclined feeding channel.

[0008] The material feeding channel includes a material feeding bin located at the top of the main support, a temporary storage bin located on the side support, a material feeding pipe located between the material feeding bin and the temporary storage bin, and a movable pipe located at the bottom of the temporary storage bin. The movable pipe is a corrugated pipe bent towards the shell-forming head.

[0009] The adjustment mechanism includes a drive motor and an adjustment screw fixed to the bottom of the main support. The drive motor drives the slider located on the adjustment screw to move left and right. The inner sides of the drive motor and the adjustment screw are respectively connected to the end of the movable tube by steel wire ropes. The movable tube is also equipped with a sensor for anti-collision detection.

[0010] This technical solution improves the feeding channel and adjustment mechanism to achieve anti-collision detection function of the shell-breaking machine's material tube during use. Specifically, the shell-breaking machine uses cylinders to power the shell-breaking head, enabling it to extend and retract. By controlling the cylinder's air intake and exhaust, the shell-breaking head achieves rapid and precise extension and retraction. Supports are securely clamped to the shells on both sides of the shell-breaking head via clamping parts. The main support and side supports jointly support the inclined feeding channel, considering not only structural stability but also optimizing the material flow path. The feeding bin, feeding pipe, and temporary storage bin ensure continuous and stable material flow. The movable pipe, acting as the final barrier for material release, features a corrugated design with bends towards the shell-breaking head, ensuring smooth material release while providing flexibility to adapt to different working conditions. The adjustment mechanism, through the combined use of a drive motor and adjusting screw, adjusts the position of the movable pipe. The rotation of the drive motor causes the slider to move left and right on the adjusting screw, thus fine-tuning the position of the movable pipe. Sensors on the movable pipe monitor the distance between the shell-breaking head and the movable pipe in real time. When the distance is less than a set value, the sensor sends a signal, triggering an anti-collision detection mechanism to prevent the shell-breaking head from colliding with the movable pipe.

[0011] In addition, the anti-collision detection device for the feed tube of the aluminum electrolysis overhead crane shell-breaking machine proposed in this utility model also has the following additional technical features:

[0012] According to one embodiment of the present invention, the sensor is a photoelectric sensor, which is used to detect the distance information between the shell-breaking head and the movable tube.

[0013] In this technical solution, a photoelectric sensor is used to detect the distance between the shell-breaking head and the moving tube in the anti-collision detection of the shell-breaking machine. When the distance between the two is less than a preset safety value, the sensor will send a signal to obtain the relative position between the shell-breaking head and the moving tube in real time and accurately, thereby preventing collisions caused by excessive proximity.

[0014] According to one embodiment of the present invention, the detection device further includes a PLC controller, which is connected to the sensor, the drive motor and the cylinder respectively. The input terminal of the PLC controller is connected to the photoelectric sensor, and the output terminal of the PLC controller is connected to the drive motor and the cylinder respectively.

[0015] In this technical solution, the input terminal of the PLC controller is connected to the photoelectric sensor to receive distance information sent by the sensor; the output terminal is connected to the actuators such as the drive motor and cylinder to control the drive motor to drive the adjusting screw to move to the right, away from the shell-breaking head; reduce the frequency of the cylinder, and stop the shell-breaking machine's operation when necessary to avoid impacting the moving tube.

[0016] According to one embodiment of the present invention, a photoelectric alarm is also provided on the top of the main support, and the photoelectric alarm is connected to the PLC controller.

[0017] In this technical solution, the photoelectric alarm is connected to the PLC controller. When the PLC detects a potential collision risk, it will trigger the alarm to issue an alarm signal.

[0018] According to one embodiment of the present invention, the feeding channel stores fluoride salt material, which is released into the electrolytic cell near the shelling head through a movable tube.

[0019] In this technical solution, fluoride salts are important raw materials in the aluminum electrolysis process. By controlling their release location and capacity, the smooth progress of the electrolysis process is ensured.

[0020] According to one embodiment of the present invention, both the feeding bin and the temporary storage bin are equipped with electromagnetic valves connected to a PLC controller at their bottoms.

[0021] In this technical solution, the PLC controller controls the opening and closing of the solenoid valve as needed to regulate the flow rate of the material; by controlling the opening time and degree of the solenoid valve, the flow rate of the fluoride material is controlled.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] The distance between the punching head and the moving tube is monitored in real time by photoelectric sensors, which effectively prevents collisions caused by excessive proximity; the PLC controller, in conjunction with the drive motor and adjusting screw, enables the adjustment of the position of the moving tube.
