Description

Technical Field

[0001] This application relates to the field of furnace dismantling equipment, and in particular to a novel extended arm for a furnace dismantling machine. Background Technology

[0002] Furnace dismantling machines, as crucial equipment in the industrial sector, are widely used in furnace dismantling operations in industries such as steel and chemicals. With the rapid development of modern industry, furnace dismantling machines play an irreplaceable role in improving work efficiency, reducing labor intensity, and ensuring operational safety. However, with the diversification and complexity of production demands, the technical limitations of traditional furnace dismantling machines are gradually becoming apparent. For example, their lack of flexibility and adaptability is particularly prominent when handling furnaces of varying heights or distances. This not only limits the application range of furnace dismantling machines but also places higher demands on operators. Therefore, improving the design of the key component of the furnace dismantling machine, the operating arm, has become an important direction for enhancing the overall performance of the equipment.

[0003] To address the issue of non-adjustable boom length, existing technologies typically employ the following methods: One is to replace booms of different lengths to meet varying operational needs. This method is simple and direct, but requires frequent shutdowns for component replacement, making it cumbersome and time-consuming. The second method involves adding a hydraulic telescopic mechanism, using hydraulic cylinders to extend and retract the boom. This allows for dynamic length adjustment, but the complexity and high cost of the hydraulic system increase maintenance difficulty. The third method uses a multi-segment connection structure, connecting multiple boom segments with bolts or clips to achieve length adjustment. However, this approach is prone to overall instability due to loose connections in practical use.

[0004] Regarding the aforementioned technologies, existing solutions often fail to simultaneously balance ease of adjustment and structural stability. For example, changing the manipulator arm is inefficient and unsuitable for rapid operation; while hydraulic telescopic mechanisms enable dynamic adjustment, their high cost and complex maintenance limit their application; multi-segment connection structures, though less expensive, have not effectively addressed the stability issues at the connections; and while multi-stage adjustment mechanisms offer good flexibility, uneven stress in practical applications can lead to localized deformation or failure. Therefore, effectively addressing the instability caused by increased manipulator arm length while ensuring adjustable arm length has become a pressing technical challenge. Utility Model Content

[0005] To address the aforementioned issues, this application provides a novel extended arm for a furnace dismantling machine.

[0006] This application provides a novel extended arm for a furnace dismantling machine, comprising a first support mechanism on which a movable rod is slidably connected; a power mechanism disposed on the first support mechanism and the movable rod, the power mechanism being used to move the movable rod; a second support mechanism disposed on the movable rod, the second support mechanism being capable of supporting the movable rod; and a transmission mechanism, at least one set of the transmission mechanism being disposed between the support mechanism and the movable rod, the transmission mechanism including a connecting plate disposed on the support mechanism, a first rack disposed on the side of the connecting plate pointing towards the movable rod, and a transmission assembly disposed on the movable rod, the transmission assembly meshing with the first rack, the transmission assembly being capable of driving the second support mechanism to move.

[0007] By adopting the above technical solution, the sliding connection between the first support mechanism and the moving rod enables the adjustability of the moving rod, thus adapting to operational needs under different working conditions. The power mechanism makes the movement of the moving rod more convenient and efficient, improving the working efficiency of the furnace dismantling machine. The second support mechanism supports the moving rod, enhancing the stability and load-bearing capacity of the entire extended arm. The meshing design of the connecting plate and the first rack in the transmission mechanism, along with the transmission component, allows for precise control of the movement of the second support mechanism, ensuring operational accuracy and reliability.

[0008] Preferably, the first support mechanism includes a first support plate, a support column is provided on the first support plate, a support sleeve is provided on the support column, and the movable rod is slidably connected inside the support sleeve.

[0009] By adopting the above technical solution, the first support mechanism forms a stable support structure through the first support plate and the support column. The support sleeve provides sliding space for the moving rod, allowing the moving rod to slide smoothly within the support sleeve, thereby improving the stability and reliability of the entire extended arm.

[0010] Preferably, the power mechanism includes baffles at both ends of the supported sleeve, a first air inlet connected to the supported sleeve, a second air inlet connected to the supported sleeve, and a baffle plate on the outer edge of the moving rod, the baffle plate being disposed inside the supported sleeve and positioned between the first air inlet and the second air inlet.

[0011] By adopting the above technical solution, the movement of the moving rod can be precisely controlled by pneumatic drive. Specifically, gas is introduced into the support sleeve through the first and second air inlets, respectively. The gas pushes the baffle plate to slide along the inner wall of the support sleeve, thereby driving the moving rod to reciprocate. This design is not only simple in structure and low in cost, but also effectively improves the operational flexibility and work efficiency of the extended arm of the furnace dismantling machine. In addition, the baffle prevents gas leakage, ensures the stability and reliability of power transmission, and further enhances the performance of the entire device.

[0012] Preferably, the second support mechanism includes a support rod slidably disposed on the movable rod, the support rod passing through the movable rod and perpendicular to the movable rod, a second rack being provided at the end of the support rod pointing towards the transmission assembly, the second rack meshing with the transmission assembly, and a fine-tuning component being provided at the end of the support rod pointing towards the ground.

[0013] By adopting the above technical solution, the support rod is slidably mounted on and perpendicular to the moving rod, allowing for flexible position adjustment to adapt to different working scenarios. The second rack meshes with the transmission assembly, enabling precise control of the support rod's movement by the transmission assembly, thus achieving effective support for the moving rod. The fine-tuning assembly further enhances the stability of the support rod, maintaining the balance of the extended arm of the furnace dismantling machine in complex terrain, ensuring the safety and reliability of the operation process.

[0014] Preferably, the fine-tuning component includes a support sleeve, a second support plate is provided at the end of the fine-tuning component pointing towards the ground, a fine-tuning plate is slidably connected inside the fine-tuning sleeve, a fine-tuning spring is provided between the fine-tuning plate and the second support plate, and the end of the support plate away from the second support plate is connected to the support rod.

[0015] By adopting the above technical solution, a slidingly connected fine-tuning plate is installed inside the support sleeve of the fine-tuning component, and elastic support is provided by a fine-tuning spring. This allows the fine-tuning plate to automatically adjust its position according to the ground conditions, thereby achieving fine-tuning of the height of the second support plate and ensuring stable contact between the second support plate and the ground. At the same time, the support plate connects the fine-tuning component to the support rod, ensuring the stability of the overall structure and improving the adaptability of the extended arm of the furnace dismantling machine in complex terrain.

[0016] Preferably, the transmission assembly includes two sets of support seats disposed on the moving rod, a rotating shaft rotatably connected to the support seats, a plurality of first gears disposed on the drive shaft, the first gears meshing with the first rack, and a second gear disposed on the drive shaft, the second gear meshing with the second rack.

[0017] By adopting the above technical solution, the transmission assembly can achieve synchronous drive of the first and second racks. Specifically, the support base mounted on the moving rod provides a stable mounting foundation for the rotating shaft. The first gear on the rotating shaft meshes with the first rack, thereby transmitting power to the second support mechanism and ensuring its movement along a predetermined trajectory. Simultaneously, the second gear on the drive shaft meshes with the second rack, further enhancing the accuracy and stability of the transmission. This design effectively improves the overall motion coordination of the extended arm, reduces energy loss, and enhances the operational precision of the equipment.

[0018] Preferably, it further includes a locking mechanism, wherein the locking mechanism is provided with parallel grippers on the moving rod, the transmission end of the parallel grippers is movable to the support rod, and the side of the transmission end of the parallel grippers pointing towards the support rod is provided with a friction surface.

[0019] By adopting the above technical solution, the locking mechanism can effectively fix the position of the support rod. Specifically, the parallel grippers set on the moving rod can contact the support rod through their transmission end, and increase the friction between the two by using the friction surface, thereby achieving stable locking of the support rod, preventing it from moving unexpectedly during operation, and improving the stability and safety of the entire extended arm structure.

[0020] Preferably, a guard plate is provided on the side of the movable rod away from the second support mechanism.

[0021] By adopting the above technical solution, the guard plate is set on the side of the moving rod away from the second support mechanism, which can effectively prevent the moving rod from excessive displacement or detachment from the support structure during movement, thereby improving the stability and safety of the entire extended arm.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Through the sliding connection between the first support mechanism and the moving rod, and the action of the power mechanism, the length of the extended boom can be quickly adjusted to effectively meet the operational needs of different heights and distances. Compared with the traditional method of changing the operating boom, this design eliminates the need to stop the machine to replace parts, significantly improving work efficiency. Furthermore, compared with complex hydraulic telescopic mechanisms, this solution has a simple structure, reducing equipment costs and maintenance difficulty, and providing a reliable guarantee for the efficient operation of the furnace dismantling machine under complex working conditions.

[0024] 2. The meshing design of the first rack and pinion in the transmission mechanism ensures smooth power transmission and coordinates the movement between the moving rod and the second support mechanism. This design not only improves the stability of the extended arm during extension and retraction but also effectively solves the problem of structural deformation or failure caused by the increased length, thereby enhancing the overall reliability of the equipment.

[0025] 3. The second support mechanism, through the cooperation of the support rod and the fine-tuning component, further enhances the precise control capability of the extended arm's end. The support rod can be adjusted under the action of the moving rod, while the fine-tuning component can achieve fine adjustment through the fine-tuning spring, thereby ensuring that the extended arm maintains good adaptability and operational accuracy in various operating scenarios, and is particularly suitable for furnace dismantling operations with high positioning requirements.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application provides a novel extended arm for a furnace dismantling machine, as referenced in its embodiments. Figure 1 It includes a first support mechanism 1, a power mechanism 2, a second support mechanism 3, and a transmission mechanism 4. A movable rod 101 is slidably connected to the first support mechanism 1. The power mechanism 2 is set on the first support mechanism 1 and the movable rod 101 to drive the movable rod 101 to move. The second support mechanism 3 is set on the movable rod 101 to provide support. The transmission mechanism 4 is connected between the support mechanism and the movable rod 101 to realize motion transmission, thereby solving the problem of unstable support when the extended arm is too long.

[0031] Specifically, the first support mechanism 1 includes a first support plate 102 and a support column 103. The support column 103 is disposed on the first support plate 102, and a support sleeve 104 is provided on the support column 103. The moving rod 101 is slidably connected inside the support sleeve 104. The first support plate 102 and the support column 103 provide a stable base, and the guide groove inside the support sleeve 104 guides the moving rod 101 to slide axially, ensuring that the sliding process is smooth and without deviation.

[0032] refer to Figure 2 The power mechanism 2 includes a baffle 201, a first air inlet 202, a second air inlet 203, and a baffle 204. Baffles 201 are provided at both horizontal openings of the support sleeve 104, providing good sealing. The support sleeve 104 has a first air inlet 202 and a second air inlet 203, which are used to introduce compressed air to push the moving rod 101 to slide. The first air inlet 202 and the second air inlet 203 are connected to an external air pump. The baffle 204 is located on the outer edge of the moving rod 101, separating the support sleeve 104 between the first air inlet 202 and the second air inlet 203. The baffle 204 and the moving rod 101 are integrally cast or otherwise designed to ensure that they will not detach during sliding.

[0033] The working principle of the power mechanism 2 is as follows: by introducing compressed air into the first air inlet 202 or the second air inlet 203, a pressure difference is formed in the support sleeve 104, which pushes the baffle plate 204 to drive the moving rod 101 to slide along the support sleeve 104, thereby realizing the length adjustment of the extension arm.

[0034] refer to Figure 1 as well as Figure 2 The second support mechanism 3 includes a support rod 301 and a fine-tuning component 303. The support rod 301 is vertically inserted into the movable rod 101, and is located within and perpendicular to the movable rod 101. A second rack 302 is provided on the side of the support rod 301 pointing towards the first support mechanism 1, and the end of the support rod 301 pointing towards the ground is connected to the fine-tuning component 303. The fine-tuning component 303 includes a fine-tuning sleeve 3031, a second support plate 3032 is provided below the fine-tuning sleeve 3031, a fine-tuning plate 3033 is provided inside the fine-tuning sleeve, and a fine-tuning spring 3034 is provided between the fine-tuning plate 3033 and the second support plate 3032. The fine-tuning plate 3033 is slidably connected within the fine-tuning sleeve 3031, and the other end of the fine-tuning plate 3033 is fixedly connected to the support plate.

[0035] The working principle of the second support mechanism 3 is as follows: the support rod 301 is connected to the moving rod 101 through a sliding connection to achieve the support function of the moving rod 101; the fine adjustment spring 3034 drives the second support plate 3032 to move vertically by contraction to ensure that the second support plate 3032 is set on the ground.

[0036] refer to Figure 1 as well as Figure 2 The transmission mechanism 4 includes a connecting plate 401, a first rack 402, and a transmission assembly 403. The connecting plate 401 is mounted on the support sleeve 104, and in one embodiment, it is an L-shaped plate. The first rack 402 is located on the side of the connecting plate 401 facing the moving rod 101. The transmission assembly 403 includes a support base 4031, a rotating shaft 4032, a first gear 4033, and a second gear 4034. The support base 4031 is mounted on the moving rod 101 and rotatably connected to the rotating shaft 4032. The rotating shaft 4032 is equipped with the first gear 4033 and the second gear 4034. The first gear 4033 meshes with the first rack 402, and the second gear 4034 meshes with the second rack 402. Force is transmitted through gear meshing, ensuring smooth and reliable movement.

[0037] The working principle of the transmission mechanism 4 is as follows: the first rack 402 meshes with the first gear 4033, converting the horizontal square reciprocating motion of the moving rod 101 into the rotational motion of the rotating shaft 4032; the second gear 4034 meshes with the second rack 302, converting the rotational motion into the vertical reciprocating motion of the support rod 301, thereby realizing the length adjustment and the synchronous motion of the support rod 301.

[0038] refer to Figure 1 as well as Figure 2 The locking mechanism 5 is mounted on the moving rod 101 and includes a parallel gripper 501 and a friction surface 502. The transmission end of the parallel gripper 501 can move to the support rod 301, and the friction surface 502 is provided on the side of its transmission end pointing towards the support rod 301. In one embodiment, the friction surface 502 is made of rubber, which has good anti-slip properties. Through the locking mechanism 5, the support rod 301 can be fixed at a specific position to prevent sliding due to external forces, further improving the stability of the structure.

[0039] The working principle of the locking mechanism 5 is as follows: when the moving rod 101 slides to the target position, the parallel gripper 501 is activated to clamp the support rod 301. The friction surface 502 contacts the support rod 301 to generate friction, thereby preventing the support rod 301 from sliding and ensuring the stability of the structure in a specific position.

[0040] refer to Figure 1 In one embodiment, a guard plate 105 is added to the side of the movable rod 101 away from the second support mechanism 3 and is fixed to the end of the movable rod 101 with bolts. The function of the guard plate 105 is to prevent the movable rod 101 from sliding excessively beyond the safe range, thus providing a limiting protection function.

[0041] The working principle of the guard plate 105 is as follows: when the moving rod 101 slides to the limit position, the baffle 201 will block further sliding, so as to avoid structural damage due to excessive sliding and play the role of limit protection.

[0042] The overall principle is as follows: the length adjustment function of the extended arm is achieved through the cooperation of sliding connection and gear transmission. Specifically, the power mechanism 2 uses compressed air to push the moving rod 101 to slide, and the transmission mechanism 4 converts the sliding into the movement of the support rod 301 through gear meshing. At the same time, the fine-tuning component 303 can compensate for the error caused by the length change, ensuring the stability of the overall structure. This design not only improves the convenience of adjustment, but also provides additional support for the robotic arm when the length is increased, preventing instability caused by the swaying of the robotic arm, and significantly improves the operational flexibility and work efficiency of the furnace dismantling machine.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
