Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prebaked anode disassembling machines, in particular to a limiting system for prebaked anode disassembling machines. Background Art
[0002] In the process of roasting prebaked anodes for aluminum electrolysis, the anode carbon blocks are usually operated by the raw anode marshaling unit and the roasted carbon block disassembling unit. The raw anodes are stored in the horizontally arranged carbon block warehouse and transported to the anode roasting workshop by the stacking crane and the chain conveyor. In the anode roasting workshop, the raw anodes are marshaled into a vertically arranged anode group of six or seven blocks by the marshaling unit, and the carbon blocks are arranged in an alternating manner. Then, the roasting multifunctional crane loads them into the anode roasting furnace for roasting. The roasted anodes are lifted by the multifunctional crane to the carbon block cleaning machine for disassembly and cleaning. The cleaned carbon blocks are re-marshaled according to specifications and sent to the carbon block warehouse.
[0003] Among them, the center push rod of the disassembly machine is the component with the highest failure rate. In the current disassembly machine, the forward limit switch and the backward limit switch of the center push rod are installed above the center push rod, and the induction blocks that cooperate with the forward limit switch and the backward limit switch are set at both ends of the upper part of the center push rod. The carbon block is pushed to the working position of the center push rod by the side push rod, and then pushed out to the horizontal turntable by the center push rod for disassembly. The forward and backward states of the center push rod are controlled by the limit switch, but because the position of the limit switch is easily affected by the block coking material trapped on the center push rod, the limit switch is sensed in advance, causing misoperation, and then causing the carbon block to fail to be pushed into place or collide. This not only increases the labor intensity, but also easily leads to mechanical damage and increased production costs. At the same time, there is a greater safety risk. Utility Model Content
[0004] The utility model aims to provide a prebaked anode disassembly machine limit system to solve the above technical problems, improve work efficiency, reduce the failure rate of disassembly, and ensure orderly production.

[0006] Furthermore, the sensing blocks are two blocks which are vertically spaced apart, and the two sensing blocks are both adjustable and fastened on the connecting chain.
[0007] Furthermore, the sensing block is limited to move vertically within a range between the front position sensor and the rear position sensor.
[0008] Furthermore, it also includes a second horizontal slide rail, the center line of the second horizontal slide rail is arranged colinearly with the center line of the first horizontal slide rail, and the second horizontal slide rail is provided with a horizontal turntable at the far end of the push block driving mechanism.

[0019] Example
[0020] like Figure 1-3 As shown, in this embodiment, a limiting system of a prebaked anode disassembling machine is mainly disclosed, which is used for limiting the pushing of carbon blocks 9, including a first horizontal slide rail 1, on which a push block driving mechanism 2 for pushing the carbon blocks 9 is slidably connected, one end of the push block driving mechanism 2 is connected to a vertically movable sensing block 4 through a connecting chain 3, a pulley 5 bypassing the connecting chain 3 is provided between the push block driving mechanism 2 and the sensing block 4, and a front position sensor 61 for limiting the forward pushing of the push block driving mechanism 2 and a rear position sensor 62 for limiting the retreat of the push block driving mechanism 2 are vertically arranged from top to bottom on one side of the sensing block 4, the front position sensor 61 and the rear position sensor 62 are both electrically connected to the push block driving mechanism 2, and it should be noted that The push block driving mechanism 2 can be a push rod driven by a motor to slide linearly along the first horizontal slide rail 1. When the push block driving mechanism 2 pushes the carbon block 9, the sensing block 4 rises and approaches the forward position sensor 61. After approaching and sensing, the push block driving mechanism 2 is controlled to stop moving to achieve the push limit. When the push block driving mechanism 2 retreats, the sensing block 4 descends and approaches the rearward position sensor 62. After approaching and sensing, the push block mechanism is controlled to stop moving to achieve the retreat limit. After bypassing the pulley 5 through the connecting chain 3, the horizontal displacement of the push block driving mechanism 2 is converted into the vertical displacement of the sensing block 4, which effectively avoids the influence of the block coking material on the sensor, improves work efficiency, reduces the failure rate of disassembly, and ensures the orderly development of production.
[0021] Furthermore, in a specific implementation, the above-mentioned sensing blocks 4 provided in the embodiment of the utility model are two blocks vertically spaced apart, and the two sensing blocks 4 can be adjustably fastened on the connecting chain 3. Specifically, the sensing blocks 4 are fastened to the connecting chain 3 by radially penetrated bolts, or by a clamp connection, to achieve an adjustable fastening connection between the sensing blocks 4 and the connecting chain 3, which can effectively adjust the pushing and retracting distance of the push block driving mechanism 2.
[0022] Furthermore, in a specific implementation, the sensing block 4 provided in the embodiment of the utility model is limited to move vertically within the range between the front sensor 61 and the rear sensor 62. The sensing block 4 has a certain weight and falls naturally. In the initial state, the sensing block 4 is close to the rear sensor 62.
[0023] Furthermore, in a specific implementation, the above-mentioned embodiment provided in the utility model also includes a second horizontal slide rail 7, the center line of the second horizontal slide rail 7 is arranged colinearly with the center line of the first horizontal slide rail 1, and the second horizontal slide rail 7 is provided with a horizontal turntable 8 at the far end of the push block driving mechanism 2. It should be noted that under the pushing action of the push block driving mechanism 2, the carbon block 9 slides linearly on the second horizontal slide rail 7 and slides toward the horizontal turntable 8 for disassembly.
[0024] Furthermore, in the specific implementation, the center line of the above-mentioned first horizontal slide rail 1 provided in the embodiment of the utility model and the central rotation plane of the pulley 5 are located in the same vertical plane, ensuring the smoothness and accuracy of sliding, reducing the friction loss of the system during operation, and improving the service life and efficiency of the system.
[0025] Furthermore, in the specific implementation, the above-mentioned connecting chain 3 provided in the embodiment of the utility model is a steel rope or an iron chain, which has a strong load-bearing capacity and wear resistance, can ensure the stability and reliability of the system during long-term operation, reduce maintenance costs and failure rates, and improve the overall performance and economy of the system.
