Abstract
Description
Technical Field
[0001] This utility model relates to the field of box-type electric furnace transfer technology, and in particular to a fixed structure for box-type electric furnace transfer. Background Technology
[0002] Box-type electric furnaces are widely used in industrial processing such as material heat treatment, metal smelting, and ceramic sintering due to their advantages of small size and precise temperature control. Although relatively small, box-type electric furnaces are still quite heavy. To facilitate manual handling, they are designed with a modular assembly mechanism. However, manual handling and reassembly not only increase the labor intensity of workers but also increase the probability of the box-type electric furnace being bumped or knocked during transportation, which can easily affect its subsequent operation.
[0003] To address the aforementioned technical problems, prior art patent application number 202121392435.7 discloses a transport structure for a box-type electric furnace. This device comprises a loading vehicle consisting of four casters at the bottom of a base, along with a handle mechanism mounted on the base. A first fixing mechanism and three sliding grooves are located on the top of the loading vehicle. A second, third, and fourth fixing mechanism are respectively installed within the three sliding grooves. The first and second fixing mechanisms are distributed laterally, while the third and fourth mechanisms are distributed longitudinally. After the box-type electric furnace is placed on top of the loading vehicle, the second, third, and fourth fixing mechanisms are moved and locked sequentially, enclosing the box-type electric furnace between the first, second, third, and fourth pressure plates, thus improving the stability of the transported box-type electric furnace. However, the aforementioned prior art requires moving the second, third, and fourth fixing mechanisms separately to allow them to work with the first fixing mechanism to enclose the box-type electric furnace before locking them in their moved positions. This fixing operation is cumbersome and relatively inefficient. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a fixing structure for box-type electric furnace transfer, so as to solve the problems that the fixing operation steps are relatively cumbersome and the fixing operation efficiency is relatively low.
[0005] Based on the above objectives, this utility model provides a fixed structure for transporting a box-type electric furnace, including two horizontal limiting parts and two vertical limiting parts alternately arranged on the top of the loading vehicle, wherein the horizontal limiting parts and the vertical limiting parts have the same structure.
[0006] The lateral limiting part includes a slide seat mounted on the loading vehicle and an L-shaped limiting block hinged to the top of the slide seat.
[0007] A support platform is provided between the ends of the four L-shaped limit blocks that are close to each other.
[0008] At least two pillars are fixed to the bottom of the support platform, and the bottom ends of the pillars are inserted into square holes provided on the loading vehicle.
[0009] When fixing the box-type electric furnace, the weight of the box-type electric furnace is used to push the support platform down, and the support platform simultaneously pushes the four L-shaped limit blocks so that the ends of the blocks that are close to each other deflect downwards, and the other ends deflect upwards to a vertical state, thus wrapping and fixing the box-type electric furnace in the horizontal direction.
[0010] Preferably, the fixing structure further includes a vertical groove on one of the vertical inner walls of the square hole and a slider slidably disposed in the vertical groove, with one side of the slider fixedly disposed at the bottom end of the outside of the support column.
[0011] Preferably, the right angle of the L-shaped limiting block is hinged to the top of the slide block, and one end of the L-shaped limiting block located at the bottom of the support platform is the short end, while the other end of the L-shaped limiting block is the long end.
[0012] Preferably, the fixing structure further includes two drive units arranged in a cross shape on the loading vehicle, the drive units being used to drive two opposing slides to move closer or further apart.
[0013] Preferably, the driving part includes two guide grooves and a driving member disposed between the two guide grooves, and the slide is slidably sleeved inside the guide grooves.
[0014] Preferably, the fixing structure further includes two transverse extensions and two longitudinal extensions that are alternately arranged on the four vertical surfaces of the support platform.
[0015] Preferably, the horizontal extension portion has the same structure as the vertical extension portion. The horizontal extension portion includes an extension plate inserted through the vertical surface of the support platform and protrusions provided on two opposite vertical surfaces of the extension plate. Two U-shaped levers are provided opposite each other on the short end of the L-shaped limiting block, and the protrusions are located inside the U-shaped levers.
[0016] Preferably, the opening of the U-shaped lever is parallel to the long end of the L-shaped limiting block, and the U-shaped lever is slidably disposed on the vertical surface of the short end of the L-shaped limiting block.
[0017] The beneficial effects of this utility model are:
[0018] This invention, by placing one side of each of the four L-shaped limiting blocks at the four boundaries of the bottom of the support platform, allows the box furnace to be lowered vertically onto the support platform. The larger weight of the box furnace presses down on the support platform, and the support platform simultaneously pushes the free ends of the four L-shaped limiting blocks towards the center of the platform. This constrains the box furnace's degrees of freedom in both longitudinal and transverse directions, reducing the number of steps required to fix the box furnace on the loading vehicle and improving the efficiency of the fixing operation. Furthermore, two driving parts can drive the two opposing transverse and longitudinal limiting parts to move closer or further apart simultaneously. This allows for adaptation to the bottom dimensions of the box furnace while expanding the support area of the support platform. Therefore, it is suitable for the transfer and fixing of box furnaces of different sizes and also improves the stability of the box furnace during transport. Attached Figure Description

[0028] like Figures 1 to 4 As shown, a fixed structure for transporting a box-type electric furnace includes two horizontal limiting parts 1 and two vertical limiting parts 2 alternately arranged on the top of the loading vehicle in a circumferential direction. The horizontal limiting parts 1 and the vertical limiting parts 2 have the same structure.
[0029] The lateral limiting part 1 includes a slide 12 mounted on the loading vehicle and an L-shaped limiting block 11 hinged to the top of the slide 12.
[0030] A support platform 4 is provided between the ends of the four L-shaped limiting blocks 11 that are close to each other. That is, the end of the L-shaped limiting block 11 that is close to the support platform 4 is located at the bottom of the support platform 4. This allows the support platform 4 to use the gravity of the box furnace to simultaneously drive the ends of the four L-shaped limiting blocks 11 that are far from the support platform 4 to deflect upwards and move towards the outside of the box furnace at the same time. This achieves the goal of surrounding the box furnace in the horizontal direction and constraining its degree of freedom in the horizontal direction, thereby improving the stability of the box furnace during transportation and preventing it from shaking in the horizontal direction.
[0031] At least two pillars 9 are fixed to the bottom of the support platform 4, and the bottom end of the pillars 9 is inserted and connected to the square hole 7 provided on the loading vehicle.
[0032] When fixing the box-type electric furnace, the weight of the box-type electric furnace is used to push the support platform 4 downward, and the support platform 4 simultaneously pushes the four L-shaped limit blocks 11 so that one end of each block is close to the other and deflects downward, and the other end of each block is deflected upward to a vertical position, thus fixing the box-type electric furnace in the horizontal direction. When unloading, the box-type electric furnace can be suspended by a truss so that the four L-shaped limit blocks 11 can be reset synchronously, reducing the fixing operation steps of the box-type electric furnace on the loading vehicle and improving the loading or unloading efficiency of the box-type electric furnace.
[0033] like Figures 2 to 4As shown, the fixed structure also includes a vertical groove 8 on one of the vertical inner walls of the square hole 7 and a slider 10 slidably disposed in the vertical groove 8. One side of the slider 10 is fixed to the bottom of the outside of the support column 9. This design can constrain the degree of freedom of the support platform 4 while making it only able to move in a straight line in the vertical direction, thereby improving the lifting stability of the support platform 4.
[0034] like Figure 1 , Figure 3 and Figure 4 As shown, the right angle of the L-shaped limiting block 11 is hinged to the top of the slide block 12, and one end of the L-shaped limiting block 11 located at the bottom of the support platform 4 is the short end, and the other end of the L-shaped limiting block 11 is the long end.
[0035] The fixed structure also includes two transverse extensions 5 and two longitudinal extensions 6 that are alternately arranged on the four vertical surfaces of the support platform 4.
[0036] The horizontal extension section 5 has the same structure as the vertical extension section 6. The horizontal extension section 5 includes an extension plate 52 that passes through the vertical surface of the support platform 4 and protrusions 53 provided on two opposite vertical surfaces of the extension plate 52. Two U-shaped levers 51 are provided opposite each other on the short end of the L-shaped limiting block 11, and the protrusions 53 are located inside the U-shaped levers 51.
[0037] The opening of the U-shaped lever 51 is parallel to the long end of the L-shaped limiting block 11, and the U-shaped lever 51 is slidably disposed on the vertical surface of the short end of the L-shaped limiting block 11.
[0038] With this design, the distance between the two opposing L-shaped limiting blocks 11 can be adjusted by the drive unit 3 so that the distance matches the length and width of the bottom of the box furnace. The size of the unfolded area of the extension plate 52 can also be stretched or shortened simultaneously to match the size of the bottom of the box furnace, thereby improving the stability of the box furnace.
[0039] like Figure 2 and Figure 3 As shown, the fixed structure also includes two drive units 3 arranged in a cross shape on the loading vehicle. The drive units 3 are used to drive the two opposing slides 12 to move closer or further apart.
[0040] The drive unit 3 includes two guide grooves 31 and a drive member 32 disposed between the two guide grooves 31. The drive member 32 includes a hidden groove disposed at the center of the top of the loading vehicle and a first bevel gear rotatably disposed in the hidden groove. The slide 12 is slidably sleeved inside the guide groove 31. A lead screw is rotatably disposed between the hidden groove and the guide groove 31. A second bevel gear is provided at one end of the lead screw. The first bevel gear meshes with the second bevel gear. One end of the lead screw passes laterally through the threaded hole on the slide 12. The first bevel gears in the two drive units 3 have different diameters and are vertically coaxially distributed opposite each other inside the hidden groove.
[0041] The two adjacent second bevel gears have different diameters. This design allows the power transmission directions of the two drive units 3 to intersect in the horizontal plane, which can both avoid mutual interference and stabilize the movement of the slide block 12.
[0042] Working principle: The box-type electric furnace is suspended above the support platform 4 using a truss. Then, the box-type electric furnace is placed on top of the support platform 4. Under the gravity of the box-type electric furnace, the support platform 4 is pushed down, which simultaneously pushes the long ends of the four L-shaped limiting blocks 11 upward and close to the vertical surface outside the box-type electric furnace until the long ends of the L-shaped limiting blocks 11 are vertical and attached to the vertical surface outside the box-type electric furnace. This completes the fixing of the box-type electric furnace. When unloading, the box-type electric furnace only needs to be lifted by the truss to be removed. No further disassembly is required, which improves the efficiency of fixing the box-type electric furnace on the loading vehicle. Furthermore, when the size of the box furnace changes, the spacing between the two corresponding L-shaped limit blocks 11 can be adjusted by individually controlling the corresponding drive unit 3, so that the spacing matches the size of the bottom of the box furnace. At the same time, the expansion plate 52 can be pulled out or retracted synchronously by the cooperation of the U-shaped lever 51 and the protrusion 53, thereby expanding or shrinking the support surface of the support platform 4 and adjusting the support surface of the support platform 4 to match the bottom of the box furnace, thus improving the stability of the box furnace after it is lowered.
