Description

Technical Field

[0001] This utility model relates to the technical field of aluminum electrolysis equipment, specifically to an anti-tipping device for anode carbon blocks used in aluminum electrolysis. Background Technology

[0002] In the electrolytic aluminum production process, anode carbon blocks are the core raw material and require multiple stages such as assembly, transportation, use, and waste electrode recycling. Among these, the stability of anode carbon blocks (including new blocks and replaced waste electrodes) during handling and placement directly affects production safety and operational efficiency. Existing technologies have explored solutions to prevent anode carbon blocks from tipping over. For example, utility model patent CN 219547123U discloses an anti-tipping device for anode carbon blocks used in aluminum electrolysis. This device clamps the anode carbon block onto the anode tray using a clamping mechanism. It uses an inclined support rod and upper jaws to support and limit the guide rod of the anode carbon block, effectively solving the problem of easy tipping of anode waste electrodes in the tray. Its structure is simple and easy to install, and it achieves anti-tipping protection in certain scenarios.

[0003] However, in actual large-scale production operations, the above-mentioned existing devices still have limitations in their applicability: on the one hand, their support structure only uses a single set of support rods and jaws to act on the guide rod, and the support point is single. When the anode carbon block is large in size, heavy in weight, or the ground at the work site is uneven, the overall anti-overturning ability is limited, and there is still a risk of tipping over. Utility Model Content

[0004] The purpose of this invention is to provide an anti-tipping device for anode carbon blocks used in aluminum electrolysis, which aims to solve the problem in the background art where replaced anode residues are easily tipped over in the anode tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-tipping device for anode carbon blocks used in aluminum electrolysis, comprising a mobile trolley and a support frame mounted on the mobile trolley. The support frame includes a first inclined support frame, a second inclined support frame, a vertical frame, an inclined beam, and a horizontal frame. One end of the first and second inclined support frames is respectively located on the front and rear sides of the upper middle part of the mobile trolley. The other ends of the first and second inclined support frames are connected together and fixed to the bottom end of the vertical frame. The top end of the vertical frame is fixedly connected to the bottom end of the inclined beam. The middle part of the horizontal frame is fixedly connected to the top end of the inclined beam. Limiting rods are fixedly connected to both ends of the horizontal frame. The two sets of limiting rods are arranged opposite to each other. A stabilizing mechanism is also provided on the mobile trolley.

[0006] Furthermore, the stabilizing mechanism includes a cylinder, a reinforcing arm, a supporting base plate, and a counterweight. Two cylinders are provided and spaced apart on the left and right sides of the upper end of the mobile trolley. A guide sleeve is provided between the piston rod of the cylinder and the middle of the lower inner surface of the mobile trolley. The piston rod end of the cylinder is fixedly connected to the reinforcing arm. The lower end of the reinforcing arm is provided with a supporting base plate. A toothed anti-slip pad is fixedly connected to the lower surface of the supporting base plate. The counterweight is fixedly installed in the middle of the upper surface of the supporting base plate.

[0007] Furthermore, a reinforcing bar is provided between the mobile trolley and the top of the vertical frame.

[0008] This utility model has the following beneficial effects: This utility model provides an anti-tipping device for anode carbon blocks used in aluminum electrolysis. It features multi-point collaborative support, which distributes the force more evenly. The counterweight acts directly on the supporting base plate, significantly lowering the overall center of gravity of the device and reducing the risk of tipping over from the source. Compared with existing structures that rely solely on clamping or single-point support, it offers greater stability under inclined ground or sudden external forces. The mobile trolley is equipped with universal wheels with brakes at the bottom, enabling flexible movement of the device on the work site. It is suitable for scenarios involving frequent transfers in multiple areas such as electrolysis workshops and assembly workshops. Attached Figure Description

[0010] like Figures 1 to 2 As shown, the anode carbon block anti-tipping device disclosed in this utility model is primarily designed to solve the problem of anodes easily tipping over during handling and placement. Through the coordinated action of a modular support structure and a stabilizing mechanism, reliable support and anti-tipping protection for the anode are achieved. The device as a whole includes a mobile trolley 1, a support assembly, and a stabilizing mechanism. Each component is made of high-strength metal materials (such as Q235 carbon steel or stainless steel) to ensure that the structural strength meets the anode load-bearing requirements, while also considering the device's mobility and operational stability.

[0011] The mobile trolley 1 serves as the supporting foundation and mobile carrier for the entire device. It adopts a frame structure design with universal wheels equipped with brakes at the four corners of the bottom, which facilitates flexible movement and quick fixation of the device on the work site. The top of the trolley is a flat mounting surface for fixing the support components and stabilizing mechanism. Its frame is assembled by welding to ensure the load-bearing rigidity of the overall structure. Metal profiles of corresponding thickness can be selected according to the weight specifications of the anode to meet the usage requirements under different working conditions.

[0012] The support assembly includes a first diagonal brace 2, a second diagonal brace 3, a vertical frame 4, a diagonal beam 5, a horizontal frame 6, and a limiting rod 7. All components are fixed by welding or bolting to ensure connection strength.

[0013] The first diagonal brace 2 and the second diagonal brace 3 are symmetrical in structure and are both made of square tubes or channel steel. One end is welded and fixed to the front and rear sides of the upper middle part of the mobile trolley 1, and the other end is inclined towards the middle of the trolley and connected to it. They are fixed together at the bottom of the vertical frame 4. The angle between the diagonal brace and the top of the mobile trolley 1 is set to 60°-75°. This angle design can maximize the dispersion of the pressure transmitted from the anode to the support and improve the overturning resistance of the support.

[0014] The vertical frame 4 is made of square steel pipe and is vertically set at the middle of the top of the mobile trolley 1. The bottom end is welded and fixed to the joint of the first and second diagonal braces, and the top end is welded and connected to the bottom end of the diagonal beam 5. It plays the role of intermediate load-bearing connecting the diagonal braces and the upper structure. Its height is designed according to the placement height requirements of the anode to ensure the stability of the center of gravity after the anode is placed.

[0015] One end of the inclined beam 5 is fixed to the top of the vertical frame 4, and the other end extends in an inclined direction away from the mobile trolley 1 and is welded and fixed to the middle of the horizontal frame 6. The angle between the inclined beam 5 and the vertical frame 4 is 30°-45°.

[0016] The horizontal frame 6 is made of metal profile of the same specification as the inclined beam 5. It is set horizontally and a set of limiting rods 7 are welded and fixed at both ends. The two sets of limiting rods 7 are arranged opposite each other to form a slot structure for clamping the anode. The length of the horizontal frame 6 is designed according to the width specification of the anode to ensure that the slot can be adapted to the size of the anode. The guide rod of the anode is placed in the slot for limiting. The limiting rods 7 are made of wear-resistant steel plate with a thickness of not less than 10mm. Rubber anti-slip pads are pasted on the inner side of the limiting rods 7.

[0017] The stabilizing mechanism includes a cylinder 8, a guide sleeve 9, a reinforcing arm 10, a support base plate 11, a toothed anti-slip pad 12, and a counterweight 13, which are used to further improve the overall stability of the device after the anode is placed and prevent the device from tipping over along with the anode.

[0018] Two identical pneumatic cylinders are selected for cylinder 8 and are installed symmetrically and at intervals on the front and rear sides of the top of the mobile trolley 1. The cylinder body of cylinder 8 is fixed to the mounting base on the top of the trolley with bolts. The piston rod extends vertically downward. The working pressure of cylinder 8 is set to 0.4-0.6MPa. The extension speed and extension length of the piston rod can be adjusted by the pneumatic control system to adapt to the support requirements of different ground conditions.

[0019] The guide sleeve 9 is made of wear-resistant alloy material and is fixedly installed in the middle of the lower inner surface of the mobile trolley 1. The piston rod of the cylinder 8 passes through the guide sleeve 9. The inner hole of the guide sleeve 9 is clearance-fitted with the outer diameter of the piston rod to guide and limit, ensuring that the piston rod always remains vertical during the extension and retraction process, and avoiding unstable support due to piston rod offset.

[0020] One end of the reinforcing arm 10 is fixedly connected to the piston rod end of the cylinder 8 via a flange, and the other end is welded and fixed to the upper surface of the support base plate 11. The reinforcing arm 10 can increase the connection strength between the piston rod and the support base plate 11, distribute the support pressure, and prevent the connection from being damaged due to concentrated force.

[0021] The support base plate 11 is made of rectangular thick steel plate with a thickness of not less than 15mm. The lower surface is fixed with a toothed anti-slip pad 12 by bolts, and the upper surface is welded and fixed with a counterweight block 13 in the middle. The area of ​​the support base plate 11 is designed according to the weight of the anode and the bearing capacity of the ground to ensure that the ground pressure during support is within the allowable range of the ground and to avoid ground subsidence.

[0022] The toothed anti-slip pad 12 is made of rubber or polyurethane material, and the lower surface has evenly distributed toothed protrusions, which can significantly increase the friction between the support base plate 11 and the ground, prevent the device from sliding when under force, and improve the support stability.

[0023] The counterweight 13 is made of cast iron or concrete, and its weight is calculated based on the weight of the anode and the overall center of gravity of the device. It is generally 1 / 3 to 1 / 2 of the weight of the anode. Its function is to lower the overall center of gravity of the device, enhance the device's anti-overturning ability, and prevent the device from tipping over due to the anode's high center of gravity.

[0024] The reinforcing rod 14 is made of metal round or square tube, and its two ends are welded and fixed to the top frame of the mobile trolley 1 and the top of the vertical frame 4, respectively, forming a triangular support structure. The stability of the triangular structure can further improve the anti-tilting ability of the vertical frame 4, disperse the lateral force borne by the vertical frame 4, avoid the vertical frame 4 from bending and deforming due to excessive force, and ensure the overall structural stability of the support assembly.

[0025] The specific operation process of this utility model is as follows: The operator releases the brakes on the bottom casters of the mobile trolley 1, pushes the device to the anode tray, then locks the brakes to fix the position of the device, and places the anode guide rod inside the anode tray.

[0026] Stable mechanism deployment: Activate the pneumatic control system to control the piston rods of the two cylinders 8 to extend downwards synchronously, driving the reinforcing arm 10, the support base plate 11 and the counterweight 13 to move downwards until the toothed anti-slip pad 12 is in close contact with the ground. At this time, the support base plate 11 forms a stable support with the ground through the toothed anti-slip pad 12, while the counterweight 13 lowers the overall center of gravity of the device.

[0027] Anode placement: The anode is slowly hoisted into the slot formed by the limiting rods 7 at both ends of the horizontal frame 6 using hoisting equipment. This ensures that the outer surface of the anode is in close contact with the rubber anti-slip pads on the inner side of the limiting rods 7. The limiting rods 7 clamp and limit the anode, preventing it from moving in the horizontal direction.

[0028] Operation completed: After the anode is placed in place or the relevant work is completed, the anode is lifted out of the slot by the hoisting equipment. Then, the piston rod of the cylinder 8 is controlled to retract upward, which drives the support base plate 11 and the counterweight block 13 to reset. The universal wheel brake is released, and the device is pushed to the next working position or storage area.
