Description

Technical Field

[0001] This application belongs to the field of metallurgical technology, and in particular relates to a device for changing the arc-shaped track of an annular cooler. Background Technology

[0002] In the mining and metallurgical industry, replacing the arc-shaped track of annular cooling sintering machines has always been a challenge. Traditional replacement methods, such as having multiple people carry the 140KG track to the designated position or using tools like crowbars to lift it and manually adjust it into place, have many drawbacks. Firstly, the operation requires a large amount of manpower; each replacement requires at least 4-6 people to lift the track, plus 2 more to tighten the pressure plate bolts, resulting in high labor costs. Secondly, the working environment is harsh. The arc-shaped track is located on both sides below the annular cooling machine, less than 1.2 meters from the platform, and surrounded by a large amount of lubricant, requiring workers to work in a semi-squatting position, making the labor extremely strenuous. Furthermore, the safety risks are extremely high; a slight mishap could cause the track to detach, resulting in injuries such as being crushed or knocked down. Moreover, the replacement time is long, exceeding 30 minutes each time, severely impacting production stability and output. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art.

[0027] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0028] The following is for reference. Figures 1-3 This application describes a device for changing the arc-shaped track of an annular cooler according to an embodiment of the present application.

[0029] Please see Figure 1 , Figure 2 and Figure 3 The ring cooler arc track 200 replacement device provided in this application embodiment includes a frame 110 and a snap-fit ​​component 120.

[0030] The frame 110 includes two support members 111 extending in the front-back direction and a connector 112 extending in the left-right direction. The two support members 111 are spaced apart in the left-right direction, and the connector 112 is connected between the two support members 111. The support members 111 are used to support the arc-shaped track 200. The front end of the support member 111 is provided with a snap-fit ​​120, which is located on the lower side of the support member 111. The snap-fit ​​120 is configured to snap onto the outer edge 300 of the water seal groove. The connector 112 is spaced apart from the front end of the support member 111, and the connector 112 is provided with a gripping part that can be held by at least one person.

[0031] When fabricating frame 110, materials with sufficient strength and stability must be selected to make two support members 111 and connecting members 112. The selected materials should be able to withstand the weight of the curved track 200 and the external forces generated during operation. The support member 111 extends in the front-to-back direction, and its specific length needs to be determined based on the actual specifications of different annular coolers and operational requirements. For example, in a specific application scenario of annular cooler, the length of the support member 111 is determined through detailed on-site surveys and precise measurements, combined with the operation procedure for replacing the curved track 200, to achieve effective support and precise positioning of the curved track 200. The two support members 111 are arranged at intervals in the left-to-right direction, and the interval distance should fully consider the size of the curved track 200 to be replaced and the operating space required by the operators to ensure a smooth and safe operation.

[0032] The connector 112 extends in the left-right direction and is fixed between the two support members 111 by a reliable connection process, thereby forming a stable frame 110 structure. The connection process can employ welding, riveting, or other methods to ensure that all components of the frame 110 are firmly connected and will not loosen or shift during operation. Taking welding as an example, suitable welding methods such as argon arc welding can be selected to ensure weld quality and enhance the overall strength of the frame 110.

[0033] A specially designed snap-fit ​​component 120 is connected to the lower front end of the support component 111. The snap-fit ​​component 120 can be manufactured by machining, casting, or other molding processes. Its shape is precisely designed to fit the height of the outer edge 300 of the water seal groove, allowing it to be stably snapped onto the outer edge 300 of the water seal groove, providing a stable support base for the entire replacement device. The connector 112 is designed with a gripping part based on ergonomic principles, allowing at least one person to hold it. For example, a protrusion or groove of a specific shape can be provided on the surface of the connector 112, or auxiliary parts for easy gripping can be installed. Simultaneously, the surface of the gripping part can be treated, such as by using an anti-slip coating or roughening treatment, significantly increasing the friction when the operator grips it, improving the stability and reliability of operation.

[0034] In actual use, the assembled frame 110 is first moved to the replacement position of the arc track 200 of the annular cooler, so that the snap-fit ​​part 120 at the front end of the support 111 is accurately snapped onto the outer edge 300 of the water seal groove. The operator applies an upward lifting force through the gripping part. At this time, the device is similar to a lever structure. Using the snap-fit ​​part 120 as a fulcrum, the connecting part 112 is lifted upward, which in turn drives the support 111 to rise, thereby lifting the arc track 200 on the support 111, preparing for the subsequent replacement operation of the arc track 200.

[0035] According to the embodiment of this application, the replacement device for the arc-shaped track 200 of the annular cooler utilizes a frame 110 structure composed of a support member 111 and a connector 112. The support member 111 directly supports the arc-shaped track 200, changing the traditional method of manually carrying the track and significantly reducing labor intensity. The support structure at the front end of the support member 111 can be snapped onto the outer edge 300 of the water-sealing groove, providing a stable support point and avoiding safety risks caused by unstable support in traditional operations. The gripping part on the connector 112 facilitates force application by the operator, further improving operational stability and safety. The entire replacement device is rationally designed, effectively solving the problems of high manpower requirements, high labor intensity, high safety risks, and long replacement time in the traditional replacement process of the arc-shaped track 200 of the annular cooler. It significantly improves the efficiency and safety of replacing the arc-shaped track 200 of the annular cooler, strongly ensuring the smooth operation of production.

[0036] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, the lower end of the snap-fit ​​member 120 may be provided with a snap-fit ​​groove 121, the shape of which is configured to match the outer edge 300 of the water seal groove.

[0037] When manufacturing the snap-fit ​​component 120, a slot 121 can be formed at the lower end of the snap-fit ​​component 120 by mechanical processing, or a slot 121 can be formed between the two snap-fit ​​components 120 by setting two snap-fit ​​components 120.

[0038] The shape of the slot 121 is designed to match the outer edge 300 of the water seal groove to improve the stability of the snap-fit ​​fastener 120 and effectively prevent the snap-fit ​​fastener 120 from shifting, shaking, or coming loose during the support process. Specifically, the shape of the slot 121 can fit tightly against the outer edge 300 of the water seal groove to ensure the snap-fit ​​stability of the snap-fit ​​fastener 120. The snap-fit ​​fastener 120 and the support member 111 are rotatably connected so that the support member 111 can rotate flexibly when the snap-fit ​​fastener 120 is fixed; or, the size of the slot 121 can be slightly larger than the outer edge 300 of the water seal groove so that the snap-fit ​​fastener 120 and the outer edge 300 of the water seal groove can move relative to each other to facilitate the flexible movement of the support member 111.

[0039] In some examples, slot 121 can be a U-shaped slot.

[0040] According to some embodiments of this application, the grip portion may be provided with anti-slip texture.

[0041] Anti-slip textures can include parallel straight lines, knurled patterns, and diamond patterns. In practical use, the grip with anti-slip textures greatly improves the safety and stability of the operator. In harsh working environments such as wet and oily conditions, friction tests showed that the coefficient of friction between the grip with anti-slip textures and the operator's hand increased from 0.3 to 0.65 compared to the grip without anti-slip textures. This means that when the operator applies upward lifting force through the grip, their hand is less likely to slip, allowing for more stable force application. This ensures the smooth operation of the curved track 200 replacement device during lever operation, effectively preventing device loss of control due to hand slippage, and thus guaranteeing the smooth progress of the entire curved track 200 replacement operation.

[0042] Please see Figure 1 and Figure 2 According to some embodiments of this application, the replacement device for the arc track 200 of the annular cooler may further include a lifting lug 130 and a power component 140. The lifting lug 130 is disposed on the connecting member 112; the power component 140 is disposed above the frame 110, and the power component 140 is dynamically coupled to the lifting lug 130 through a sling.

[0043] When actually manufacturing and installing the lifting lug 130, the lifting lug 130 can be made of the same or compatible metal material as the main body of the frame 110. For example, if the main body of the frame 110 is made of Q235 steel, the lifting lug 130 should also be made of the same material to ensure that it has sufficient strength and toughness to withstand the tension during the lifting process. The lifting lug 130 can be fixed to the connector 112 by welding. Depending on the actual needs, the shape of the lifting lug 130 can be designed as U-shaped, D-shaped, etc., and its size is determined according to the tension it bears and its compatibility with the connector 112. For example, the opening width of the U-shaped lifting lug 130 can be 50mm and the thickness can be 10mm to meet the mechanical performance requirements of the device.

[0044] The selection of the power component 140 depends on the actual operational requirements of the arc track 200 replacement device for the annular cooler. If frequent and efficient track replacement is required, an electric hoist can be used as the power component 140; if the operating environment is complex and there are strict limitations on the size and weight of the power component 140, a manual hoist can also be used. The power component 140 is installed on a fixed bracket above the frame 110. This fixed bracket must have sufficient strength and stability to firmly support the power component 140. The fixed bracket is connected to the fixed structure at the work site (such as steel beams of the factory building) by bolts or welding. The power component 140 and the lifting lug 130 are connected by a sling, which can be a high-strength steel wire rope or chain. When connecting the sling to the lifting lug 130 and the power component 140, special rigging accessories, such as U-rings and shackles, are used to ensure a secure and reliable connection and prevent safety accidents such as disengagement during operation.

[0045] In actual operation, when workers need to lift frame 110 to replace curved track 200, the power unit 140 is activated. If an electric hoist is used, the motor is turned on by operating the control button, driving the drum to wind up and down the sling, thereby lifting frame 110. If a manual hoist is used, the worker pulls the chain to drive the gear transmission mechanism inside the hoist, thereby winding up and down the sling and lifting frame 110. During the lifting process, due to the firm connection between lifting lug 130 and connecting piece 112, and the reliable power coupling between the sling, lifting lug 130, and power unit 140, frame 110 can be lifted smoothly, greatly reducing the labor intensity of workers and improving the efficiency and safety of curved track 200 replacement operations.

[0046] According to some embodiments of this application, the lug 130 can be centrally located along the length of the connector 112.

[0047] Because the lifting lug 130 is centrally located along the length of the connector 112, the frame 110 remains balanced when the power unit 140 pulls the lifting lug 130 to lift the frame 110 via the sling. This balanced lifting effect prevents the frame 110 from tilting due to the offset position of the lifting lug 130, thus ensuring the stability of the curved track 200 during lifting and greatly improving the safety and accuracy of track replacement operations. Simultaneously, the centrally located lifting lug 130 allows the lifting force to be evenly distributed on the connector 112, effectively reducing the risk of deformation of the connector 112 due to uneven force and extending the service life of the device.

[0048] Please see Figure 1 and Figure 2According to some embodiments of this application, the frame 110 may also include a reinforcing member 123, which extends in the left-right direction and connects between two supporting members 111. The reinforcing member 123 and the connecting member 112 are spaced apart in the front-back direction.

[0049] When fabricating the reinforcing member 123, a material with the same material or matching performance as the supporting member 111 and the connecting member 112 should be selected. For example, if the supporting member 111 and the connecting member 112 are made of Q345 steel, the reinforcing member 123 should also be made of Q345 steel to ensure the material compatibility and consistency of mechanical properties of the entire frame 110. The shape of the reinforcing member 123 can be designed as a square tube, a round tube, or angle steel, etc., determined according to the actual structural requirements and strength calculations. If space utilization and installation convenience are considered, a square tube can be selected, with a side length generally between 40mm and 60mm. When installing the reinforcing member 123, a welding connection is used to firmly connect both ends of the reinforcing member 123 to the two supporting members 111 respectively.

[0050] The reinforcing member 123 and the connecting member 112 are spaced apart in the front-to-back direction so that the reinforcing member 123, the two supporting members 111, and the connecting member 112 form a closed frame structure, ensuring the stability of the overall structure. The connecting member 112 can be located at the rear end of the two supporting members 111 to extend the torque, facilitate force application and operation, and increase the working space. The reinforcing member 123 can be spaced apart from the front end of the supporting members 111.

[0051] In some examples, multiple reinforcements 123 may be provided.

[0052] In practical use, the reinforcement 123 significantly enhances the overall strength and stability of the frame 110. When the frame 110 bears the arc-shaped track 200, the reinforcement 123 can share the pressure borne by the support 111 and the connecting 112, greatly improving the load-bearing capacity of the frame 110. This effectively prevents deformation of the frame 110 during operation, ensuring the reliable operation of the arc-shaped track 200 replacement device for the annular cooler, extending the device's service life, and also improving the safety and efficiency of track replacement operations.

[0053] According to some embodiments of this application, the support member 111 may be provided with two limiting protrusions spaced apart in the front-rear direction, and the portion of the support member 111 between the two limiting protrusions is used to support the arc-shaped track 200.

[0054] The shape of the limiting protrusions can be designed as cylindrical, cuboid, or triangular prism, taking into account both the processing difficulty and the limiting effect on the arc-shaped track 200; no specific shape is limited. The limiting protrusions can be firmly fixed to the support member 111 by welding to ensure the stability of the overall structure and the stable limiting effect on the arc-shaped track 200. When the arc-shaped track 200 is placed on the support member 111, the two limiting protrusions effectively restrict the forward and backward displacement of the arc-shaped track 200 on the support member 111. This prevents the track from sliding or shifting during replacement, ensuring the accuracy and safety of the track replacement operation. Simultaneously, the setting of the limiting protrusions makes the support position of the arc-shaped track 200 on the support member 111 more defined and stable, contributing to improved performance of the entire replacement device.

[0055] According to some embodiments of this application, the bottom of the support member 111 may be provided with casters.

[0056] When installing the casters, they can be bolted to the bottom of the support 111. In actual use, the casters at the bottom of the support 111 greatly improve the mobility of the replacement device. Operators can easily push the replacement device and quickly move it to the replacement position on the arc track 200 of the annular cooler.

[0057] According to some embodiments of this application, both the support member 111 and the connector 112 can be made of 40mm-60mm thick steel pipe.

[0058] These steels exhibit excellent strength, toughness, and machinability, meeting the mechanical requirements of the annular cooler's arc-shaped track 200 replacement device when supporting the arc-shaped track 200 and coping with complex operating environments. Furthermore, the circular steel pipe surface has low friction, allowing for convenient and flexible adjustment of the arc-shaped track 200's position when supported on the support member 111, thus improving operational flexibility.

[0059] According to some embodiments of this application, the support member 111 and the connector 112 are perpendicular to each other, the length of the support member 111 is 1.5m-2m, and the length of the connector 112 is 1.2m-1.5m.

[0060] When determining the length of support component 111, the length is selected within the range of 1.5m-2m based on the actual structure of the annular cooler and the dimensions and position of the curved track 200. For example, for a certain model of annular cooler, after detailed on-site measurements and mechanical analysis, considering the weight distribution and support stability requirements of the curved track 200, the length of support component 111 is determined to be 1.8m. Similarly, the length of connector 112 is selected between 1.2m and 1.5m based on the working space of the annular cooler and its fit with support component 111. Assuming a specific work scenario, considering the operator's activity space within frame 110 and the support range of frame 110 for the curved track 200, the length of connector 112 is determined to be 1.3m.

[0061] The perpendicular and rationally designed lengths of the support member 111 and the connector 112 give the frame 110 structure excellent stability and load-bearing capacity. The perpendicular structure forms a stable right-angle support system, effectively distributing the weight of the curved track 200 and improving the frame 110's resistance to deformation. The length settings of the support member 111 and the connector 112 not only provide comprehensive support for the curved track 200 but also adapt to the structural characteristics and operational requirements of different annular coolers. For example, when supporting a common 2.2m long curved track 200, the frame 110 structure can stably support the track, ensuring smooth track replacement operations while providing ample operating space for operators, improving operational efficiency and safety.
