Description

Technical Field

[0001] This utility model relates to the field of crucible tilting, specifically a semi-automatic crucible tilting limiting system. Background Technology

[0002] A crucible is a container used to melt materials such as metals and ceramics. Crucibles play an important role in industrial production, especially in metallurgy, chemistry, and oil refining. When workers pour crucibles, they need to use semi-automatic tilting forklifts. However, semi-automatic tilting forklifts do not have a limit system, which makes it impossible to accurately pour each row of crucibles into the steel mold. Molten metal often spills during the pouring process due to the varying skill levels of the operators. To address these problems, the inventors have proposed a semi-automatic crucible tilting limit system to solve the aforementioned issues. Utility Model Content

[0003] To address the issue of the lack of a limit system in semi-automatic tilting forklifts, the purpose of this invention is to provide a semi-automatic crucible tilting limit system.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a semi-automatic crucible tilting and limiting system, including a mounting rod, a plurality of limiting mechanisms rotatably arranged on the top of the mounting rod, a guide mechanism arranged at the bottom of the mounting rod, and a mounting mechanism arranged at one end of the mounting rod. The limiting mechanism includes a rotating block, the bottom of which rotatably engages with the top of the mounting rod, and an L-shaped limiting block fixedly arranged on the top of the rotating block. A vertical rod is fixedly arranged on one side of the L-shaped limiting block by a first bolt, and a top plate is fixedly arranged on the top of the vertical rod. A through hole is opened at one end of the top of the top plate, and the through hole slides. The slide rod is equipped with a U-shaped retaining plate fixedly installed at its bottom end. A spring is fixedly installed between the top plate and the U-shaped retaining plate, and the spring is sleeved on the surface of the slide rod. A connecting block is fixedly installed at one end of the L-shaped limiting block. A first stop block is rotatably installed on one side of the connecting block. A fixing block is fixedly installed at the top center of the top plate. A through hole is opened on one side of the fixing block. An insert rod is fixedly installed in the through hole by a second bolt. Two square holes are opened on one side of the slide rod. The insert rod is engaged with one of the square holes. A second stop block is fixedly installed on one side of the rotating block. A gripping block is fixedly installed at the top of the slide rod.

[0005] Preferably, the installation mechanism includes an installation block, a limiting groove is formed on the top of the installation block, an opening is formed on one side of the installation block, the opening communicates with the limiting groove, a movable block is engaged in the limiting groove, one end of the installation rod passes through the opening and is fixedly engaged with one side of the movable block, installation strips are symmetrically fixed at both ends of the installation block, and multiple third bolts are threaded on one side of the installation strip.

[0006] Preferably, the guiding mechanism includes an intermediate block, a connecting rod is fixedly disposed at the bottom center of the intermediate block, a U-shaped guide plate is fixedly disposed at one end of the connecting rod, and the top of the intermediate block is fixedly engaged with the bottom of the mounting rod by a fourth bolt.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. Using L-shaped limit blocks, U-shaped clamping plates, springs, and insert rods, bend the first L-shaped limit block to a position perpendicular to the mounting rod. The structure of the semi-automatic tilting forklift tilting crucible contacts the L-shaped limit block. Loosen the second bolt, pull out the insert rod, and the U-shaped clamping plate moves down, firmly locking the structure of the semi-automatic tilting forklift tilting crucible and the L-shaped limit blocks. Repeat the operation when passing the remaining L-shaped limit blocks to ensure that each row of crucibles can be accurately poured into the steel mold, avoiding the phenomenon of molten metal spilling during the tilting process due to different operator skill levels.

[0017] 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.

[0018] Example: Figure 1-5 As shown, this utility model provides a semi-automatic crucible tilting limiting system, including a mounting rod 1. Multiple limiting mechanisms 2 are rotatably mounted on the top of the mounting rod 1, a guide mechanism 3 is mounted on the bottom of the mounting rod 1, and a mounting mechanism 4 is mounted at one end of the mounting rod 1. Each limiting mechanism 2 includes a rotating block 21, the bottom of which rotatably engages with the top of the mounting rod 1, and an L-shaped limiting block 22 is fixedly mounted on the top of the rotating block 21. The limiting mechanisms 2 facilitate limiting other parts of the semi-automatic tilting forklift. The mounting mechanism 4 facilitates the disassembly and assembly of the mounting rod 1, making maintenance convenient and quick. The guide mechanism 3 enhances the structural stability of the semi-automatic tilting forklift when tilting molten crucible.

[0019] A vertical rod 24 is fixedly installed on one side of the L-shaped limiting block 22 by the first bolt. A top plate 25 is fixedly installed on the top of the vertical rod 24. A through hole is opened at one end of the top of the top plate 25. A sliding rod 26 is slidably installed in the through hole. A U-shaped clamping plate 27 is fixedly installed at the bottom of the sliding rod 26. A spring 28 is fixedly installed between the top plate 25 and the U-shaped clamping plate 27. The spring 28 is sleeved on the surface of the sliding rod 26.

[0020] By adopting the above technical solution, the initial state of the U-shaped clamp 27 is directly above the L-shaped limiting block 22 and does not engage with the L-shaped limiting block 22. When the structure of the semi-automatic tilting forklift tilting the crucible passes the first L-shaped limiting block 22, the first L-shaped limiting block 22 is bent to a position perpendicular to the mounting rod 1. At this time, the structure of the semi-automatic tilting forklift tilting the crucible contacts the L-shaped limiting block 22, playing a preliminary limiting role. The spring 28 is always in a compressed state, exerting a downward force on the U-shaped clamp 27. The U-shaped clamp 27 moves down, firmly clamping the structure of the semi-automatic tilting forklift tilting the crucible and the L-shaped limiting block 22, playing a further limiting role on the structure of the semi-automatic tilting forklift tilting the crucible.

[0021] One end of the L-shaped limiting block 22 is fixedly provided with a connecting block 29, and a first stop block 210 is rotatably provided on one side of the connecting block 29.

[0022] By adopting the above technical solution, when the first L-shaped limiting block 22 is bent to a position perpendicular to the mounting rod 1, the first stop block 210 is rotated to make it contact the side of the mounting rod 1, which further limits the structure of the semi-automatic tilting forklift tilting the crucible.

[0023] A fixing block 211 is fixedly installed at the center of the top of the top plate 25. A through hole is opened on one side of the fixing block 211. A plug rod 213 is fixedly installed in the through hole by a second bolt 212. Two square holes 214 are opened on one side of the slide rod 26. The plug rod 213 is engaged with one of the square holes 214.

[0024] By adopting the above technical solution, when the L-shaped limiting block 22 is in the initial state, the insert rod 213 is inserted into the square hole 214 located below, so that the U-shaped clamping plate 27 is kept directly above the L-shaped limiting block 22. When the L-shaped limiting block 22 comes into contact with the structure of the semi-automatic tilting forklift tilting the crucible, the second bolt 212 is loosened, the insert rod 213 is pulled out, so that the U-shaped clamping plate 27 moves down, and engages and further limits the structure of the L-shaped limiting block 22 with the structure of the semi-automatic tilting forklift tilting the crucible.

[0025] A second stop 215 is fixedly installed on one side of the rotating block 21.

[0026] By adopting the above technical solution, the second stop 215 can ensure that the L-shaped limiting block 22 can be rotated to a position perpendicular to the mounting rod 1.

[0027] A gripping block 23 is fixedly installed at the top of the slide bar 26.

[0028] By adopting the above technical solution, the U-shaped card plate 27 can be easily lifted and released by the staff through the gripping block 23.

[0029] The mounting mechanism 4 includes a mounting block 41. A limiting groove is provided on the top of the mounting block 41. An opening 42 is provided on one side of the mounting block 41. The opening 42 communicates with the limiting groove. A movable block 43 is snapped into the limiting groove. One end of the mounting rod 1 passes through the opening 42 and is fixedly engaged with one side of the movable block 43. Mounting strips 44 are symmetrically fixed at both ends of the mounting block 41. Multiple third bolts 45 are threaded on one side of the mounting strips 44.

[0030] By adopting the above technical solution, when the device needs to be installed, the mounting block 41 and mounting strip 44 are installed and fixed on the semi-automatic tilting forklift by the third bolt 45. When the limit mechanism 2 and guide mechanism 3 need to be maintained and disassembled, the movable block 43 can be slid to disengage from the limit groove, and the limit mechanism 2 and guide mechanism 3 can be removed for maintenance.

[0031] The guide mechanism 3 includes an intermediate block 31, a connecting rod 32 is fixedly installed at the bottom center of the intermediate block 31, a U-shaped guide plate 33 is fixedly installed at one end of the connecting rod 32, and the top of the intermediate block 31 is fixedly engaged with the bottom of the mounting rod 1 by a fourth bolt 34.

[0032] By adopting the above technical solution, the structure of the semi-automatic tilting forklift tilting crucible slides along the inner wall of the U-shaped guide plate 33, which makes the structure of the semi-automatic tilting forklift tilting crucible more stable when tilting the crucible.

[0033] Working principle:

[0034] When the semi-automatic tilting forklift needs to tilt the crucible, as the tilting structure passes the first L-shaped limit block 22, the first L-shaped limit block 22 is bent to a position perpendicular to the mounting rod 1. At this time, the tilting structure of the semi-automatic tilting forklift contacts the L-shaped limit block 22, which plays a preliminary limiting role. Loosen the second bolt 212 and pull out the insertion rod 213. The spring 28 is always in a compressed state, exerting a downward force on the U-shaped clamping plate 27. The U-shaped clamping plate 27 moves down and firmly clamps the tilting structure of the semi-automatic tilting forklift and the L-shaped limit block 22, which plays a further limiting role on the tilting structure of the semi-automatic tilting forklift. When passing the second L-shaped limit block 22, the second L-shaped limit block 22 is bent to a position perpendicular to the mounting rod 1. This operation is repeated to facilitate the tilting operation of the crucible.

[0035] When the device needs to be installed, the mounting block 41 and mounting strip 44 are installed and fixed on the semi-automatic tilting forklift by the third bolt 45. When the limit mechanism 2 and guide mechanism 3 need to be maintained and disassembled, simply slide the movable block 43 to disengage it from the limit groove, and the limit mechanism 2 and guide mechanism 3 can be removed for maintenance.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
