Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0034] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0035] For ease of description, spatial relative relationship terms may be used in the text to describe the relative positional relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation other than the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or change in motion state, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "over other elements or features". Therefore, the exemplary term "below" can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0036] In industrial heat treatment processes, trolley furnaces, as common high-temperature heating equipment, are widely used in processes such as annealing, normalizing, and quenching of metal materials. After the workpieces are heat-treated, they need to be promptly transferred from the furnace to the cooling or subsequent processing area. Therefore, the stability and efficiency during the furnace discharging stage have an important impact on the overall production process.

[0037] In the high-temperature operation scenario of trolley furnaces, there are many technical bottlenecks in the existing furnace discharging tooling.

[0038] In terms of the lifting method, traditional tooling mainly relies on forklifts for furnace discharging operations. In environments where forklift operations are not suitable, such as narrow spaces and strong high-temperature radiation, it is difficult to achieve flexible and efficient lifting, which limits the convenience and applicability of the operations.

[0039] In terms of structural stability, most of the partition plates of the existing tooling adopt simple support structures. In high-temperature environments, affected by material thermal creep and gravity, they are prone to collapse and deformation, which not only reduces the furnace loading capacity but also frequently causes tooling damage, increasing the maintenance cost and downtime.

[0040] In addition, the internal structure of the existing tooling is fixed and cannot be adjusted according to the heights of different workpieces. When loading the furnace, it is difficult to achieve a reasonable layout for workpieces of different sizes, reducing the space utilization rate and production efficiency.

[0041] To solve the above technical problems in the prior art, the present application provides a multi-layer combined lifting rack, which solves problems such as inconvenient lifting, easy damage of tooling, and poor applicability during the high-temperature furnace discharging process of trolley furnaces through innovative structural design and function optimization, and improves the overall efficiency and economy of trolley furnace operations.

[0042] Refer toFigures 1-9 , the present application provides a multi-layer combined lifting frame 10, the lifting frame 10 includes a lifting frame housing 100, a positioning insertion rod 210, a load-bearing spacer 230 and a partition assembly 200. An accommodation space 101 is provided inside the lifting frame housing 100. The partition assembly 200 is placed in the accommodation space 101 and is connected to the inside of the lifting frame housing 100 through the positioning insertion rod 210 and the load-bearing spacer 230. Lifting holes 102 are provided on both sides of the lifting frame housing 100.

[0043] The transfer method of the lifting frame 10 provided by the present application is flexible, and the ladle can be freely selected to be taken out by a crane or a forklift, improving the convenience and efficiency of operation; the five-point load-bearing design of the partition 220 has high structural stability, avoiding the collapse and deformation of the partition 220 at high temperature, reducing the tooling damage, maintenance cost and downtime; the split adjustable design of the load-bearing spacer 230 has strong adaptability to workpieces being loaded into the furnace, can adjust the layout according to the height of different workpieces, and improves the utilization rate of the loading space and production efficiency.

[0044] In some embodiments, the lifting frame housing 100 is integrally precision cast with a high-strength and high-temperature-resistant alloy material and adopts a multi-layer three-dimensional structure design, which can improve the structural strength and rigidity of the lifting frame housing 100.

[0045] In some possible implementation manners, the lifting frame housing 100 includes a first side wall 110, a second side wall 120, a third side wall 130 and a fourth side wall 140. The first side wall 110 and the third side wall 130 are oppositely arranged, the second side wall 120 and the fourth side wall 140 are oppositely arranged, and the first side wall 110, the second side wall 120, the third side wall 130 and the fourth side wall 140 are sequentially connected to enclose the accommodation space 101;

[0046] Lifting holes 102 are provided on both the second side wall 120 and the fourth side wall 140, and the lifting holes 102 on the second side wall 120 are adapted to the corresponding lifting holes 102 on the fourth side wall 140.

[0047] In some possible implementation manners, the lifting holes 102 are elliptical.

[0048] By adopting the elliptical lifting holes 102, an anti-slip effect can be achieved.

[0049] Among them, the position and size of the lifting holes 102 are analyzed and optimized by mechanics. When the forklift cannot meet the transfer requirements, the crane hook can be accurately matched with the lifting holes 102 to realize the smooth lifting and taking out of the lifting frame 10 and the workpiece from the hot zone, effectively expanding the applicable scenarios of the lifting, and improving the flexibility and safety of the lifting.

[0050] In some possible embodiments, the hoisting frame body 100 further includes a bottom side 150. The first side wall 110, the second side wall 120, the third side wall 130, and the fourth side wall 140 are all connected to the bottom side 150 to form the hoisting frame body, and the partition assembly is assembled and connected to the bottom side through the positioning insertion rods and the load-bearing partition blocks.

[0051] In some possible embodiments, the partition assembly 200 includes a plurality of partitions 220. The positioning insertion rods 210 are multiple, and the multiple positioning insertion rods 210 are arranged at intervals and are respectively inserted into the bottom side 150 of the hoisting frame body 100. The multiple partitions 220 are arranged at intervals along the height direction of the positioning insertion rods 210 and are sequentially penetrated through the positioning insertion rods 210. The load-bearing partition block 230 is provided with a through hole 231, and the load-bearing partition block 230 is penetrated through the positioning insertion rod 210 through the through hole 231 and abuts against the partition 220.

[0052] Among them, the number of load-bearing partition blocks 230 between two adjacent partitions 220 can be set and adjusted according to actual conditions. For example, it can be 1, 2, 3, 4, or 5, etc. Specific values are not limited in this application.

[0053] In some possible embodiments, the load-bearing partition block 230 can be made by single-piece precision casting of a high-strength and high-temperature-resistant alloy material. This design enables the load-bearing partition block 230 to be quickly and flexibly adjusted according to the height of the loaded workpiece, that is, the partition 220. Through the combination of different split units, workpieces of various height specifications can be adapted, greatly improving the adaptability of the hoisting frame 10 to workpieces of different sizes and enhancing the practicability of the tooling under complex working conditions.

[0054] In some possible embodiments, the partition 220 can be made by integral precision casting of a high-strength and high-temperature-resistant alloy material, which reduces the overall weight while ensuring the bearing capacity.

[0055] In some possible embodiments, each partition 220 is provided with a plurality of connection holes 221 and a plurality of limiting grooves 222. The plurality of connection holes 221 are distributed at intervals. When the partition 220 is penetrated through the positioning insertion rod 210 through the connection holes 221, the load-bearing partition block 230 is partially embedded in the limiting grooves 222.

[0056] In some possible embodiments, the bottom side 150 is provided with a plurality of positioning holes, the plurality of positioning holes are distributed at intervals, each positioning hole is arranged opposite to each connection hole 221, and the plurality of positioning insertion rods 210 are in one-to-one correspondence and cooperation with the plurality of positioning holes.

[0057] In some possible embodiments, the positioning plug 210 is precision-cast from a single piece of high-strength and high-temperature-resistant alloy material. One end thereof is precisely fitted with a preset positioning hole on the bottom side 150, and the other end is precisely butted with the corresponding positioning structure of the partition plate 220. Through precise positioning and stable connection, it can effectively prevent the load-bearing partition block 230 from shifting or collapsing during high-temperature operation and loading, significantly improving the durability and reliability of the tooling from the aspect of structural stability.

[0058] In some possible embodiments, the plurality of positioning holes include a first positioning hole 151, a second positioning hole 152, a third positioning hole 153, a fourth positioning hole 154, and a fifth positioning hole 155; the first positioning hole 151, the second positioning hole 152, the third positioning hole 153, and the fourth positioning hole 154 are respectively close to the four end points of the bottom side 150, and the fifth positioning hole 155 is close to the center of the bottom side 150.

[0059] By providing the first positioning hole 151, the second positioning hole 152, the third positioning hole 153, the fourth positioning hole 154, and the fifth positioning hole 155, and each positioning hole is inserted with a positioning plug 210, in this way, the partition plate 220 can adopt an advanced five-point load-bearing layout. And because the first positioning hole 151, the second positioning hole 152, the third positioning hole 153, and the fourth positioning hole 154 are respectively arranged close to the four end points of the bottom side 150, and the fifth positioning hole 155 is arranged close to the center of the bottom side 150, a reasonable distribution of the load can be achieved, thereby effectively resisting the thermal stress and gravity in a high-temperature environment, preventing the partition plate 220 from collapsing and deforming. At the same time, by optimizing the space layout, the furnace loading capacity is increased and the production efficiency is improved.

[0060] In some possible embodiments, the positioning plug 210 includes a rod body 211 and a positioning ring 212. The positioning ring 212 is sleeved on the rod body 211, and the bottom side 150 is further provided with a positioning groove 156. When the rod body 211 is inserted into the positioning hole, the positioning ring 212 is in fit connection with the positioning groove 156.

[0061] By providing the positioning ring 212 and providing a positioning groove 156 on the bottom side 150 that cooperates with it, when the rod body 211 is inserted into the positioning hole, the positioning ring 212 can be in interference fit connection with the positioning groove 156. This structural design enables the positioning plug 210 to not only maintain stability by interference fit or friction after being inserted and fixed, but also further enhance the reliability of the connection through the shape fit between the positioning ring 212 and the positioning groove 156.

[0062] Specifically, the positioning ring 212 is partially embedded in the positioning groove 156 to form a limiting and anti-rotation structure, effectively preventing the positioning insertion rod 210 from loosening, shifting or falling off when subjected to external forces (such as vibration, collision or lateral force during operation), thereby significantly improving the stability and positioning accuracy of the connection between the positioning insertion rod 210 and the bottom side 150.

[0063] In some possible embodiments, the positioning ring 212 and the rod body 211 are integrally formed.

[0064] Integral processing and forming can better control dimensional tolerances and geometric tolerances. There is no welding seam or connection interface between the positioning ring 212 and the rod body 211. The overall structure is stronger, not prone to fracture or deformation, more suitable for complex working conditions such as high temperature, vibration or heavy load, and can effectively improve the service life and reliability of the positioning insertion rod 210.

[0065] In addition, for integral forming, there is no need to additionally assemble the positioning ring 212, reducing manual operation steps and improving production efficiency.

[0066] In some possible embodiments, the height of the positioning insertion rod 210 is equal to the height of the lifting frame body 100.

[0067] In this way, the positioning insertion rod 210 can be protected by the lifting frame body 100, avoiding the situation that the positioning insertion rod 210 slips off the tooling during the transfer of the furnace-out tooling.

[0068] Based on the above embodiments, the loading process of the lifting frame 10 provided in this application is as follows:

[0069] 1) Positioning and insertion of the positioning insertion rod 210: When loading the workpiece on the lifting frame 10, insert the positioning insertion rod 210 accurately into the outer frame of the lifting frame body 100, that is, the bottom side 150, at the preset high-precision positioning holes according to the design requirements, ensure that the positioning insertion rod 210 is firmly installed and the verticality meets the standard, and build a stable foundation for subsequent operations.

[0070] 2) Loading the first layer of workpieces: Place the workpieces steadily and accurately on the first layer of the tooling according to the furnace loading process requirements, ensure that the workpieces are placed steadily and evenly distributed, and avoid the center of gravity deviation and uneven load caused by improper placement of the workpieces.

[0071] 3) Adjustment of the load-bearing spacer 230: According to the actual height of the workpieces loaded on the first layer, select the load-bearing spacer 230 split units with appropriate height specifications and install them on the positioning insertion rod 210.

[0072] 4) Installation of the partition 220: Install the partition 220 by matching it with the positioning insertion rod 210 and the load-bearing spacer 230 through the positioning holes, ensure that the partition 220 is firmly installed, and form a stable and reliable load-bearing structure layer.

[0073] 5) Circular loading: Repeat the above steps of loading workpieces on the first layer, adjusting the load-bearing spacer block 230, and installing the partition plate 220 until the furnace loading operation of all workpieces is completed. During the furnace loading process of each layer, it is necessary to comprehensively detect and adjust the positions of the workpieces and the installation states of the load-bearing spacer block 230 and the partition plate 220 to ensure that the furnace loading quality meets the standards.

[0074] In addition, the discharging methods of the lifting frame 10 provided in the above embodiments may include the following two types:

[0075] 1) Forklift discharging: When the forklift operation conditions are available at the operation site and comply with safety regulations, drive the forklift to the side of the lifting frame 10, insert the forklift into the bottom of the tooling, slowly lift the forklift fork arms, and smoothly fork up the entire lifting frame 10, and transport it away from the hot zone of the trolley furnace according to the predetermined driving route.

[0076] 2) Hoisting discharging / Crane discharging: When the forklift cannot operate, move the crane to a suitable position above the lifting frame 10. The operator accurately places the lifting hook of the crane into the lifting hole 102 at the bottom side 150 of the frame body 100 of the lifting frame, and slowly hoist it through the crane operation control system, lift the lifting frame 10 smoothly from the hot zone, and transport it away according to the predetermined hoisting route.

[0077] In summary, the lifting frame 10 provided in this application has the following advantages:

[0078] 1. The hoisting flexibility is significantly improved: The setting of the hoisting hole 102 provides diversified hoisting means for the lifting frame 10, effectively solving the problem that the forklift cannot operate under specific working conditions. Through cooperation with the crane, efficient hoisting can be achieved in complex space environments and high-temperature and strong radiation areas, greatly improving the flexibility, applicability, and safety of hoisting operations, and meeting the requirements of different working scenarios.

[0079] 2. The structural stability is greatly enhanced: The organic combination of the multi-layer structure and the five-point load-bearing design of the partition plate 220 significantly improves the structural stability of the lifting frame 10 in high-temperature environments through advanced mechanical analysis and optimization design means. It effectively prevents the partition plate 220 from collapsing and deforming, ensures the reliability of the tooling during long-term high-temperature operations, reduces the maintenance and replacement costs caused by structural damage, and at the same time increases the furnace loading capacity, improving production efficiency and economic benefits.

[0080] 3. The workpiece adaptability is comprehensively optimized: The split and adjustable design of the load-bearing spacer block 230, combined with precise connection and positioning technologies, enables the lifting frame 10 to quickly and flexibly adapt to the furnace loading requirements of workpieces with different heights. Through simple combination and adjustment of split units, the adaptation to workpieces of different sizes can be completed in a short time, expanding the application range of the tooling, improving the flexibility and efficiency of production, and reducing the furnace loading difficulty and costs caused by workpiece size differences.

[0081] 4. The durability of the tooling is effectively improved: The precise positioning and stable connection design of the positioning plug 210 effectively prevent the unstable phenomenon of the positioning plug 210 during use and the risk of the load-bearing spacer 230 shifting and collapsing during use from the root cause of structural stability, thereby damaging the workpiece.
