[0002] During heat treatment, products are heated in a furnace and then placed in a water tank for quenching. For larger products, a forklift is typically used to remove them from the furnace and transfer them to the water tank for quenching. This process involves moving the forklift, removing the product, transferring it, and placing it down, resulting in a long time between removal from the furnace and immersion in the water, generally exceeding 100 seconds. This can negatively impact the heat treatment effect, especially for special materials, making it difficult to guarantee their performance. Therefore, a lifting gantry crane for heat treatment that can quickly transfer larger products is needed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 6 A lifting gantry for heat treatment includes a frame structure 1, a lifting platform 2, a platform structure 3, a telescopic component 4, and a lifting power structure 5. The frame structure 1 is set in a water tank. The lifting power structure 5 is fixedly installed on the upper end of the frame structure 1. The lifting platform 2 is movably assembled inside the frame structure 1 and is also assembled on the output end of the lifting power structure 5. The platform structure 3 is movably assembled on the upper surface of the lifting platform 2. The telescopic component 4 is set on the ground and its output end is assembled on the platform structure 3.

[0025] The support structure 1 serves to support and guide the lifting platform 2.

[0026] The telescopic component 4 is used to move the platform structure 3.

[0027] The lifting power structure 5 is used to drive the lifting platform 2 to move up and down.

[0028] Platform structure 3 is placed on lifting platform 2, and the product is placed on platform structure 3. When lifting platform 2 is raised or lowered, it can drive platform structure 3 and product to be raised or lowered.

[0029] Platform structure 3 is made of high-temperature resistant materials and its surface is coated with high-temperature resistant heat insulation coating.

[0030] The water tank is located underground and outside the outlet of the heating furnace. After the product is heated, it can be moved to the lifting platform 2 via the telescopic component 4. Then, the lifting platform 2 can be lowered to directly complete the water quenching of the product. The product transfer process is simple, reducing manpower and material resources during the transfer process and greatly shortening the transfer time. The entire process can be controlled within 30 seconds, thereby ensuring the performance of the product.

[0031] Specifically, such as Figures 1 to 3 As shown, the support structure 1 includes a bottom plate, columns 11 and guide plates 12. The bottom plate is located on the lower surface of the inner cavity of the pool. Four columns 11 are assembled at the four corners of the upper surface of the bottom plate. Two guide plates 12 are fixedly installed on the middle of the left and right sides of the upper surface of the bottom plate. A crossbeam 13 is fixedly installed on the upper end of the columns 11 and guide plates 12 on the same side, and the lifting power structure 5 is fixedly installed on the crossbeam 13.

[0032] The column 11 provides overall support, while the guide plate 12 guides and supports the lifting platform 2.

[0033] A flat plate is provided on the outside of the column 11, and the flat plate is placed on the ground. A triangular support plate is provided between the upper surface of the flat plate and the outer surface of the column 11 to increase the strength of the column 11.

[0034] The upper and lower ends of the guide plate 12 are respectively installed on the base plate and the crossbeam 13 to fix the guide plate 12.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, support plates 21 are fixedly installed on both the left and right surfaces of the lifting platform 2. Guide columns 22 are fixedly installed on the outer surface of the support plates 21. Channel steel 14 is fixedly installed on the inner surface of the guide plate 12, and the guide columns 22 are inserted into the channel steel 14.

[0036] Multiple sets of vertical bracing are provided between the support plate 21 and the lifting platform 2 to increase strength and stability.

[0037] The guide column 22 and the channel steel 14 work together to guide the lifting platform 2.

[0038] Specifically, such as Figure 1 As shown, there are three guide posts 22, and the three guide posts are located on the central axis of the outer surface of the support plate 21.

[0039] By setting multiple sets of guide columns 22, the stability of the lifting platform 2 on the guide plate 12 can be increased, effectively preventing the lifting platform 2 from deflecting.

[0040] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, the platform structure 3 includes a platform 31, a fixed plate 32, and side plates 34. A slider is fixedly installed on the lower surface of the platform 31. A slide rail 23 is assembled on the upper surface of the lifting platform 2, and the slider is inserted into the slide rail 23. The fixed plate 32 is fixedly installed on the left side of the upper surface of the platform 31, and the two side plates 34 are fixedly installed on the front and rear surfaces of the fixed plate 32, respectively.

[0041] The cooperation between the slider and the slide rail 23 limits the direction of movement of the platform structure 3. Corresponding tracks to the slide rail 23 are also provided on the ground outside the lifting platform 2 and inside the heating furnace so that the platform structure 3 can be moved into the heating furnace to heat the product, and at the same time, it is easy to move the platform structure 3 back onto the lifting platform 2.

[0042] The fixed plate 32 and the side plate 34 can limit the position of the product, so that the product is placed in the center as much as possible, which increases the stability during the subsequent lifting process of the lifting platform 2.

[0043] The outer surfaces of both the fixed plate 32 and the side plate 34 are provided with vertical tie rods to increase their strength.

[0044] Specifically, such as Figure 3 and Figure 5 As shown, the telescopic assembly 4 adopts a hydraulic device or an electric push rod device. The output end of the telescopic assembly 4 is fixedly installed with a telescopic plate 41. The lower surface of the outer end of the telescopic plate 41 is fixedly installed with an insert plate 42. The upper surface of the fixed plate 32 is provided with a slot 33, and the insert plate 42 is inserted into the slot 33.

[0045] The telescopic component 4 moves the telescopic plate 41, which in turn moves the platform structure 3, thus adjusting the product position.

[0046] The telescopic plate 41 is telescopic, which enables it to effectively move the platform structure 3.

[0047] Initially, the insert plate 42 is inserted into the slot 33, which can drive the platform structure 3 to move. When the telescopic plate 41 controls the platform structure 3 to move onto the lifting platform 2, the lifting platform 2 moves down, causing the insert plate 42 to separate from the slot 33. When the lifting platform 2 rises later, the insert plate 42 will re-insert and cooperate with the slot 33, and then the platform structure 3 can be moved again.

[0048] The edges of the lower surface of the insert plate 42 can be chamfered to better fit with the slot 33.

[0049] Specifically, such as Figure 3 and Figure 5 As shown, a limit rod 35 is fixedly installed on the left side of the upper surface of the platform 31, and the limit rod 35 is located on the right side of the fixed plate 32.

[0050] When transferring the product into the heating furnace, the limiting rod 35 is positioned inside the furnace and the fixing plate 32 is positioned outside the furnace. At this time, the door of the heating furnace can fall between the fixing plate 32 and the limiting rod 35. Then, the moving platform structure 3 makes the limiting rod 35 contact the door, which can effectively prevent the heat inside the heating furnace from dissipating.

[0051] Specifically, such as Figure 1 and Figure 6 As shown, lifting lugs 24 are fixedly installed on both the left and right sides of the upper surface of the lifting platform 2.

[0052] Specifically, such as Figure 1 and Figure 3 As shown, the lifting power structure 5 includes a groove wheel mounting frame 51, a double groove wheel 52, a single groove wheel 53, and ropes. The groove wheel mounting frame 51 is fixedly installed on the upper end of the upright structure 1. The double groove wheel 52 is located on the right side of the upper surface of the groove wheel mounting frame 51, and the single groove wheel 53 is located on the left side of the upper surface of the groove wheel mounting frame 51. There are two ropes. One rope passes through one groove of the double groove wheel 52 and is connected to a lifting lug 24. The other rope passes through the other groove of the double groove wheel 52 and the single groove wheel 53 and is connected to another lifting lug 24.

[0053] The outer ends of the two ropes are connected to the same power device, so when the power device is running, it can drive the two ropes to move the same distance, thereby achieving stable lifting and lowering of the lifting platform 2.

[0054] The quantity and position of the double-groove wheel 52 and the single-groove wheel 53 are adjusted.

[0055] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
