Description

Technical Field

[0001] The present invention relates to the technical field of slag raking machines, and specifically to an improved slag raking machine. Background Art

[0002] In modern industrial production, a large amount of aluminum slag is generated during the metal smelting and heat preservation processes. If this aluminum slag is not cleaned up in time, it will not only affect the product quality, but also reduce the thermal efficiency of the furnace and increase energy consumption. Baowu Aluminum Co., Ltd. faces the problem of aluminum slag treatment during the production process.

[0003] The company currently has two imported slag raking vehicles, which are responsible for removing the aluminum slag in the smelting furnace and the heat preservation furnace. However, due to long-term high-intensity operation, these two slag raking vehicles have experienced oil leakage and damage to some components, and urgent major repairs are needed. But during the equipment maintenance period, the slag raking operation cannot be carried out normally, seriously affecting the production progress. If new slag raking vehicles are purchased, not only is the cost high, but also the procurement cycle is long, making it difficult to quickly meet the production requirements.

[0004] Under this background, transforming a forklift into a slag raking machine has become a practical solution. Forklifts are widely used in the industrial field, with good mobility and a certain load-bearing capacity, and are easy to operate, and the maintenance technology is mature. By using a forklift for transformation, its advantages can be fully utilized, while reducing the equipment procurement cost and manufacturing cycle. By removing the original forklift forks and lifting devices, modifying the counterweight, adding a hydraulic cooler, transforming the hydraulic pipeline and electrical system, and then installing a specially designed slag raking mechanism, such as a frame, arm swing device, pitching mechanism, slag raking arm assembly, etc., an ordinary forklift can be transformed into a slag raking machine that meets the production requirements.

[0005] This transformation solution can not only solve the urgent problem of the current production operation of Baowu Aluminum Co., Ltd., but also provide an innovative idea and method for other enterprises facing similar problems. By reasonably using existing resources for transformation and upgrading, enterprises can reduce costs while improving production efficiency and enhancing their market competitiveness. Summary of the Invention

[0006] Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides an improved slag raking machine, which solves the problems raised in the above background art.

[0007] (II) Technical Solution In order to achieve the above object, the present invention specifically adopts the following technical solutions: An improved slag raking machine includes a mobile vehicle, a frame is provided on the mobile vehicle, and a pitching mechanism is provided on the frame; The pitching mechanism includes that the bottom of the frame is connected to the front axle of the mobile vehicle in a split form and can rotate up and down. The top of the frame is rotatably connected to a pitching oil cylinder, and the bottom of the pitching oil cylinder is rotatably connected to the shell of the mobile vehicle; An arm swinging device is arranged on the frame; The arm swinging device includes a swinging oil cylinder rotatably connected to the frame. The front end of the swinging oil cylinder is rotatably connected to a position at the bottom of the sliding sleeve in the slag scraping arm assembly. The bottom of the sliding sleeve is snap-fitted and rotatably connected to the connecting seat. The connecting seat is fixedly connected to a position on the side of the frame and is horizontal with the swinging oil cylinder; The slag scraping arm assembly includes a sliding sleeve. A slag scraping arm slides in the middle of the sliding sleeve. The slag scraping arm is rectangular, and reinforcing plates are fixedly connected around it. The bottom reinforcing plate is rotatably connected to the bottom roller. The bottom roller is rotatably connected below the sliding sleeve. The side wall reinforcing plate is rotatably connected to the side roller. The side roller is fixed to the side wall of the sliding sleeve through a bearing seat and rotates in contact with the slag scraping arm. Two fixators are fixedly connected to the top of the slag scraping arm. A chain belt fitting on the upper part of the slag scraping arm is fixedly connected between the two fixators. A power device is arranged on the sliding sleeve; The power device includes a housing fixed to the upper part of the sliding sleeve. A servo motor is fixedly connected to one side wall of the housing. The output end of the servo motor is fixedly connected to a power roller rotating inside the housing. The power roller is meshed and driven on the chain belt to move the slag scraping arm; A slag scraping shovel is fixedly connected to the front end of the slag scraping arm.

[0008] Further, the pitching mechanism is pushed by the telescoping of the pitching oil cylinder to make the frame pivot around the front wheel axis, realizing the pitching movement of the frame in the vertical direction from 3° to -10° downward, and the frame is vertical at 0°.

[0009] Further, through the telescoping of the swinging oil cylinder of the arm swinging device, a horizontal rotation of 0° - 90° is realized.

[0010] Further, three chain belts are in a group. Tooth rollers for positioning are rotatably connected to the sliding sleeve. There are two tooth rollers in the power device, and the tooth rollers are meshed to position the rotation of the chain belt.

[0011] Further, pressure rollers are arranged on both sides of the power device in the middle of the sliding sleeve. The pressure rollers are in an "I" shape. The two ends are pressed against the reinforcing plates to rotate, and the middle shape fits on the chain belt for pressing and driving.

[0012] Further, limiters are arranged at both ends of the slag scraping arm. When the slag scraping arm expands and contracts, the limiters abut against the pressure rollers at both ends of the sliding sleeve to prevent the slag scraping arm from detaching from the sliding sleeve.

[0013] Further, there are three circumferentially distributed teeth on the power roller, and the chain belt is engaged through the teeth.

[0014] Further, a forklift is selected for the transformation of the mobile vehicle.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides an improved slag skimmer, which has the following beneficial effects: This solution has remarkable results in cost control and resource utilization. Selecting a forklift to transform the slag skimmer greatly reduces the equipment procurement cost and avoids the high investment in developing a new mobile chassis. For example, Baowu Aluminum uses the existing Hangcha forklift for transformation, saving a large amount of funds. At the same time, it effectively revitalizes the idle or existing forklift resources of the enterprise, avoids equipment waste, and the transformation process is simple. Based on the mature structure of the forklift, it reduces the design and R & D costs, shortens the manufacturing cycle, quickly meets the urgent production needs, and solves the slag skimming problem efficiently at low cost, improving the economic benefits of the enterprise.

[0016] From the perspectives of performance, operation and maintenance, this solution has outstanding advantages. The forklift itself has strong mobility and stable load-bearing. After transformation, it provides good mobility and load-bearing performance for the slag skimmer, ensuring the stable operation of each component and the accurate slag skimming operation. Its technology is mature and it is convenient to integrate new components. Moreover, the existing maintenance personnel of the enterprise can maintain it after simple training, reducing the maintenance difficulty and cost. The operators are familiar with the operation logic of the forklift and can easily get started with the new equipment, reducing the training cost and time, improving the production efficiency, and enhancing the overall competitiveness of the enterprise in the slag skimming operation link.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment As Figures 1-3 shown, an improved slag skimmer proposed in an embodiment of the present invention includes a mobile vehicle 1, a frame 2 is provided on the mobile vehicle 1, and a pitching mechanism is provided on the frame 2; The mobile vehicle 1 provides the mobility for the entire slag skimmer, enabling it to move flexibly in the working site and reach different slag skimming operation positions. Its connection method with the frame 2 provides stable support for the subsequent movements of each mechanism, ensuring the stability of each mechanism during operation; As Figures 1-3 shown, the pitching mechanism includes that the bottom of the frame 2 is connected to the front axle of the mobile vehicle 1 in a half-coupling form and can rotate up and down. The top of the frame 2 is rotatably connected to a pitching oil cylinder 3, and the bottom of the pitching oil cylinder 3 is rotatably connected to the shell of the mobile vehicle 1; The frame 2 serves as the core support structure, bearing the weights and working loads of components such as the arm swing device, the pitching mechanism, the slag skimming arm assembly, and the power device. Its connection method with other components ensures the relative positional relationship between each mechanism, enabling each mechanism to work together to achieve the various functions of the slag skimmer; As Figures 1-3 shown, the pitching mechanism is composed of the half-coupling connection between the bottom of the frame 2 and the front axle of the mobile vehicle 1, and the rotational connection between the top of the frame 2 and the pitching oil cylinder 3. The other end of the pitching oil cylinder 3 is rotatably connected to the shell of the mobile vehicle 1, and the frame 2 is pushed to rotate around the front wheel axis by the telescopic movement of the oil cylinder.

[0021] The pitching movement of the frame 2 in the vertical direction from 3° to -10° downward is realized, changing the height and angle of the slag skimming arm assembly to adapt to the slag skimming operation requirements at different heights and depths, ensuring that the slag skimming shovel 19 can accurately reach the target position for slag skimming.

[0022] As Figure 4 shown, an arm swing device is provided on the frame 2; The arm swing device includes a swing oil cylinder 4 rotatably connected to the frame 2. One end of the swing oil cylinder 4 is rotatably connected to the frame 2, and the other end is rotatably connected to the bottom of the sliding sleeve 5 in the slag skimming arm assembly. The bottom of the sliding sleeve 5 is snap-fitted and rotatably connected to the connecting seat 6, and the connecting seat 6 is fixed to the side of the frame 2 and is horizontal with the swing oil cylinder 4.

[0023] By the telescopic movement of the swing oil cylinder 4, the sliding sleeve 5 is driven to rotate around the connecting seat 6, enabling the slag raking arm assembly to achieve a horizontal rotation of 0° - 90°, expanding the horizontal range of the slag raking operation, and allowing the slag rake to perform slag raking operations in a larger area.

[0024] As Figures 4-6 shown, the slag raking arm assembly includes a sliding sleeve 5. A slag raking arm 7 slides in the middle of the sliding sleeve 5. The slag raking arm 7 is rectangular, and reinforcement plates 8 are fixedly connected around it. The bottom reinforcement plate 8 is rotatably connected to a bottom roller 9, and the bottom roller 9 is rotatably connected below the sliding sleeve 5. The sidewall reinforcement plate 8 is rotatably connected to a side roller 10, and the side roller 10 is fixedly mounted on the sidewall of the sliding sleeve 5 through a bearing seat and rotates in contact with the slag raking arm 7. Two fixators 11 are fixedly connected to the top of the slag raking arm 7, and a chain belt 12 that fits on the upper part of the slag raking arm 7 is fixedly connected between the two fixators 11. A power device is provided on the sliding sleeve 5; Through the telescopic movement of the slag raking arm 7 in the sliding sleeve 5, the adjustment of the slag raking distance is achieved. The reinforcement plates 8, bottom roller 9, and side roller 10 ensure the smooth sliding of the slag raking arm 7. The chain belt 12 and the fixators 11 cooperate with the power device to provide a power transmission path for the telescopic movement of the slag raking arm 7; As Figures 4-6 shown, the power device includes a housing 16 fixed to the upper part of the sliding sleeve 5. A servo motor 17 is fixedly connected to one sidewall of the housing 16. The output end of the servo motor 17 is fixedly connected to a power roller 18 that rotates inside the housing 16. The power roller 18 is meshed and driven on the chain belt 12 to move the slag raking arm 7; The servo motor 17 provides power to drive the power roller 18 to rotate. The power roller 18 drives the slag raking arm 7 to move inside the sliding sleeve 5 through meshing with the chain belt 12. It is the power source for the telescopic movement of the slag raking arm 7 and determines the telescopic speed and force of the slag raking arm 7; As Figures 4-6 shown, a slag raking shovel 19 is fixedly connected to the front end of the slag raking arm 7; As a component directly performing the slag raking operation, under the drive of the slag raking arm 7, it penetrates into the smelting furnace or holding furnace to rake out the aluminum slag. Its fixed connection method ensures stability during the slag raking process and ensures the efficient progress of the slag raking operation.

[0025] The slag scraper is composed of a mobile vehicle 1, a frame 2, a pitch mechanism, an arm swing device, a slag scraper arm assembly, a power unit and a slag scraper 19. The mobile vehicle 1 is modified from a forklift to provide mobility for the whole machine. The frame 2 serves as a supporting structure to carry various components. Its bottom is connected to the half of the front axle of the mobile vehicle 1, and its top is rotatably connected to the shell of the mobile vehicle 1 through a pitch cylinder 3. When the pitch mechanism is working, the pitch cylinder 3 telescopes and pushes the frame 2 with the front wheel axis as the hinge point, realizing the pitch movement of the frame 2 from 3° in the vertical direction to -10° downward, thereby adjusting the height angle of the slag scraping operation.

[0026] In the arm swing device, one end of the swing cylinder 4 is rotatably connected to the frame 2, and the front end is rotatably connected to the bottom of the sliding sleeve 5 of the slag scraping arm assembly. The bottom of the sliding sleeve 5 is engaged and rotated on the connecting seat 6, and the connecting seat 6 is fixed to the side of the frame 2. When the swing cylinder 4 is extended or retracted, it drives the sliding sleeve 5 to rotate around the connecting seat 6, realizing a 0°-90° horizontal rotation, thereby expanding the slag scraping operation range.

[0027] The sliding sleeve 5 of the slag scraper arm assembly is equipped with a rectangular slag scraper arm 7. The reinforcement plates 8 around the slag scraper arm 7 are rotatably connected to the bottom roller 9 and the side roller 10 respectively to ensure the smooth sliding of the slag scraper arm 7. Two fixtures 11 are fixed on the top of the slag scraper arm 7, and the chain belt 12 is connected between the two. The servo motor 17 of the power device is fixed on the upper shell 16 of the sliding sleeve 5, and the power roller 18 at its output end rotates in the shell 16 and engages the chain belt 12. When the servo motor 17 is running, the power roller 18 drives the chain belt 12, thereby moving the slag scraper arm 7 back and forth in the sliding sleeve 5, realizing the telescopic action of the slag scraper arm 7.

[0028] The slag scraper 19 is fixed at the front end of the slag scraper arm 7. With the coordinated operation of various mechanisms, the slag scraper 19 reaches the designated position and performs the slag scraping operation. In addition, the sliding sleeve 5 is provided with a pressure roller 13 and a toothed roller 14. The pressure roller 13 is in the shape of an "I" character, with both ends pressed on the reinforcement plate 8 for rotation, and the middle part is pressed with the chain belt 12 for transmission; the toothed roller 14 engages and positions the chain belt 12 for rotation to ensure the stable operation of the chain belt 12. Limiters 15 are provided at both ends of the slag scraper arm 7, which resist the pressure rollers 13 at both ends of the sliding sleeve 5 when extending and retracting, preventing the slag scraper arm 7 from detaching from the sliding sleeve 5, ensuring safe and reliable operation.

[0029] like Figures 3-6 As shown, in some embodiments, the chain belts 12 are grouped into three, and are connected to the positioning toothed rollers 14 on the sliding sleeve 5 for rotation, and two toothed rollers 14 are in two power devices, and the toothed rollers 14 mesh with the positioning chain belts 12 for rotation; The chain belts 12 are grouped in three pieces, and this grouping method helps to enhance the stability and uniformity of power transmission. The multiple chain belts 12 work together to better withstand the tension generated when the slag scraper arm 7 moves, avoiding problems such as breakage or slipping due to excessive force on a single chain belt 12, and ensuring that the slag scraper arm 7 can stably perform telescopic movements; A positioning gear roller 14 is rotatably connected to the sliding sleeve 5, and two gear rollers 14 are located at the power device. The gear roller 14 meshes with the chain belt 12. During the movement of the chain belt 12, the gear roller 14 plays a key role in positioning and guiding. On the one hand, the teeth of the gear roller 14 are precisely matched with the chain links of the chain belt 12 to prevent the chain belt 12 from running off track during operation, ensuring that the chain belt 12 always runs on the correct track. On the other hand, the rotation of the gear roller 14 can reduce the frictional resistance between the chain belt 12 and the sliding sleeve 5, making the rotation of the chain belt 12 smoother, reducing energy loss, and improving the working efficiency of the slag skimmer. When the servo motor 17 in the power device drives the power roller 18 to rotate, the power roller 18 drives the chain belt 12 to move. At this time, the two gear rollers 14 located at the power device are in close meshing with the chain belt 12, assisting the power roller 18 in transmitting power and making the movement of the chain belt 12 more stable. At the same time, the positioning function of the gear roller 14 ensures the accuracy of the chain belt 12 during power transmission, thereby ensuring that the slag skimming arm 7 can extend and retract along the set trajectory to achieve precise slag skimming operations.

[0030] As Figures 3-6 shown, in some embodiments, pressure rollers 13 are provided in the middle of the sliding sleeve 5 on both sides of the power device. The pressure rollers 13 are in the shape of a "worker" character, with both ends pressing and rotating on the reinforcement plate 8, and the middle part being shaped to fit on the chain belt 12 for pressing and driving. Both ends of the pressure roller 13 are pressed and rotated on the reinforcement plate 8, and the reinforcement plate 8 is fixed around the slag skimming arm 7. This connection method enables the pressure roller 13 to provide additional support force for the slag skimming arm 7. During the extension and retraction of the slag skimming arm 7, the pressure roller 13 shares part of the weight of the slag skimming arm 7 and acts together with the bottom roller 9 and the side roller 10 to reduce the local pressure of the slag skimming arm 7 on the sliding sleeve 5, reduce the wear degree of the components, and extend the service life of the equipment.

[0031] The middle part of the pressure roller 13 is shaped to fit on the chain belt 12 for pressing and driving. When the power roller 18 of the power device drives the chain belt 12 to move, the middle part of the pressure roller 13 is in close contact with the chain belt 12, increasing the frictional force between the chain belt 12 and the pressure roller 13, making the chain belt 12 more stable during transmission and not prone to slipping. This helps to ensure the effective transmission of power, ensuring that the slag skimming arm 7 can extend and retract at the expected speed and force, and improving the efficiency and accuracy of the slag skimming operation.

[0032] Since the pressure rollers 13 are distributed on both sides of the power device, connected to the reinforcement plate 8 at both ends, and cooperate with the chain belt 12 in the middle, when the chain belt 12 drives the slag scraping arm 7 to move, the pressure rollers 13 can play a certain role in restraining and balancing the movement of the slag scraping arm 7. It can prevent the slag scraping arm 7 from shaking or deviating during the sliding process, enabling the slag scraping arm 7 to smoothly extend and retract along the axis direction of the sliding sleeve 5, ensuring that the slag scraping shovel 19 can accurately reach the target position during the slag scraping operation and improving the quality of the slag scraping operation.

[0033] As Figures 3-6 shown, in some embodiments, limiters 15 are provided at both ends of the slag scraping arm 7. When the slag scraping arm 7 extends and retracts, the limiters 15 abut against the pressure rollers 13 at both ends of the sliding sleeve 5 to prevent the slag scraping arm 7 from detaching from the sliding sleeve 5; During the operation of the slag scraper, the slag scraping arm 7 frequently extends and retracts. If the slag scraping arm 7 extends or retracts excessively, it is very likely to detach from the sliding sleeve 5, which will cause equipment damage and even pose a threat to the safety of the operator. The presence of the limiters 15 sets a boundary for the extension and retraction of the slag scraping arm 7. When the slag scraping arm 7 extends and retracts to a position close to the limit, the limiters 15 will abut against the pressure rollers 13 at both ends of the sliding sleeve 5 to prevent the slag scraping arm 7 from moving further, thereby preventing the slag scraping arm 7 from detaching from the sliding sleeve 5 and ensuring the normal operation of the equipment and the safety of the operator.

[0034] Once the slag scraping arm 7 detaches from the sliding sleeve 5, the slag scraper will not be able to perform the slag scraping operation normally, and a large amount of time and cost will be required for maintenance. The cooperation between the limiters 15 and the pressure rollers 13 ensures that the slag scraping arm 7 always slides normally within the sliding sleeve 5, maintaining the stability and reliability of the equipment. This helps to improve the working efficiency of the slag scraper, reduce the downtime caused by equipment failures, and ensure that the production operation can proceed continuously and smoothly.

[0035] The detachment of the slag scraping arm 7 from the sliding sleeve 5 will cause serious damage to the slag scraping arm 7, the sliding sleeve 5 and related connecting components, accelerate the wear of the equipment, and shorten the service life of the equipment. By preventing the slag scraping arm 7 from detaching from the sliding sleeve 5, the limiters 15 reduce the risk of damage to equipment components, reduce unnecessary repairs and replacements, thereby extending the overall service life of the slag scraper and saving the enterprise the cost of equipment renewal and maintenance.

[0036] As Figures 3-6 shown, in some embodiments, three teeth are circumferentially distributed on the power roller 18, and the chain belt 12 is engaged through the teeth; Increasing Friction and Power Transmission Efficiency: There are three circumferentially distributed teeth on the driving roller 18, which increases the contact area and friction with the chain belt 12. When the servo motor 17 drives the driving roller 18 to rotate, these teeth can mesh more firmly with the chain belt 12, avoiding slipping, enabling power to be transferred from the driving roller 18 to the chain belt 12 more efficiently, and then driving the slag skimming arm 7 to move smoothly, ensuring the coherence and stability of the slag skimming operation.

[0037] Precise Positioning and Transmission Stability: The three teeth are evenly distributed on the circumference of the driving roller 18 and mesh precisely with the chain belt 12, providing precise positioning for the chain belt 12 during operation and ensuring the position accuracy of the chain belt 12 during transmission. This helps to maintain the smooth movement of the slag skimming arm 7, enabling it to maintain a stable speed and direction during telescoping, improving the accuracy and quality of the slag skimming operation, and avoiding the shaking of the slag skimming arm 7 caused by unstable transmission of the chain belt 12, which affects the slag skimming effect.

[0038] Adapting to Working Intensity and Extending Service Life: The design of the three teeth increases the meshing reliability between the driving roller 18 and the chain belt 12, enabling it to better withstand the large loads during the slag skimming operation. During frequent slag skimming operations, even when encountering a certain degree of impact or resistance, the meshing structure between the teeth and the chain belt 12 can remain stable and is not easily damaged. This structural design helps to extend the service life of the driving roller 18 and the chain belt 12, reduce the frequency of equipment maintenance and component replacement, lower the usage cost, and improve the overall performance and economy of the slag skimmer.

[0039] As Figures 1-3 shown, in some embodiments, the mobile vehicle 1 is selected to be transformed from a forklift; Selecting a forklift to transform the mobile vehicle 1 is based on the characteristics of the forklift itself and the requirements of the slag skimming operation. This transformation method has many advantages and can effectively meet the various requirements of the slag skimmer in actual work.

[0040] Utilizing Existing Resources and Reducing Costs: Using an existing forklift for transformation avoids the high costs of specifically designing and manufacturing a brand-new mobile chassis. Enterprises do not need to invest a large amount of funds in research and development and production of new mobile equipment. They only need to carry out targeted transformation on the forklift to convert it into a mobile carrier of the slag skimmer, greatly reducing the equipment procurement and manufacturing costs. For example, Baowu Aluminum Company transformed a 20-ton Hangcha forklift on-site into a slag skimmer, making full use of the existing equipment resources and saving funds.

[0041] Having Good Mobility and Load-bearing Capacity: The forklift itself has strong mobility and a certain load-bearing capacity.

[0042] Facilitating Transformation and Integration: The structure of the forklift is relatively simple, and the layout of each component is relatively clear, facilitating transformation and integration of new components.

[0043] Mature technology and operation foundation: Forklifts are widely used in the industrial field, with mature technology and a perfect maintenance system.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
