Description

Technical Field

[0001] This utility model relates to the field of mold lifting technology, specifically to a simple insert-type lifting anti-detachment clamping plate device. Background Technology

[0002] In the use of molds, it is often necessary to transfer them, which usually requires lifting rods and lifting lugs. Because molds are generally large and heavy, some even weighing several tons, if the lifting rods slip during transfer and cause the mold to fall, it can lead to serious safety production failures with unimaginable consequences. Existing lifting rod anti-slip structures have a low safety factor, and the lifting rods are prone to falling off when moving back and forth inside the mold under lifting force, posing a potential safety hazard. Therefore, a simple insertable lifting anti-slip clamping plate device is proposed to solve this problem.

[0003] Among them, Chinese utility model patent application number CN201921669789.4 discloses an anti-detachment lifting rod for transferring molds, which relates to the field of mold lifting technology. This utility model involves an anti-detachment ring loosely fitted onto the large-diameter section of a stepped assembly, with an internal threaded sleeve engaging with the threaded section of the small-diameter section of the stepped assembly. The aim is to reduce the difficulty of installing the lifting rod in the early stages of the lifting rod's manufacturing process, lower the probability of the lifting rod falling off, and improve the safety factor. However, this improvement, which requires changes to the lifting rod's manufacturing process, has high production costs, is expensive, has low universality, and is not conducive to large-scale production.

[0004] Among them, Chinese utility model patent application number CN202323520736.5 discloses a gravity-based anti-falling lifting rod, which relates to the field of mold auxiliary structure technology. This utility model has a U-groove on the surface of the rod along the axial direction, so that the lifting rod can only be installed and disassembled when the U-groove is aligned with the anti-falling part, thereby enabling the rod to achieve a self-locking function and effectively reducing the risk of the lifting rod falling off. This utility model improves the anti-falling process in the early stages of the lifting rod's production process, requiring changes to the lifting rod's manufacturing process, resulting in high production costs, hindering large-scale mass production, reducing its social adoption rate, and having low universality.

[0005] Among them, Chinese utility model application CN202022726109.7 discloses an anti-falling lifting rod. This utility model relates to the field of mechanical processing technology. The utility model places a lifting base at the lifting hole of the mold base, inserts a lifting rod, and the lifting rod connects the lifting lug and the mold together. Rotating the lifting rod fixes it in the lifting lug, preventing it from sliding. The entire fixing operation is convenient, quick, and labor-saving, solving the problem of workers having to tighten multiple nuts one by one, which is time-consuming and labor-intensive. However, this utility model has a difficulty in aligning the lifting rod with the suspended part, greatly increasing the operational difficulty. Furthermore, other adhesives can easily adhere to the exposed lifting rod, potentially causing problems with the fit between the lifting rod and the lifting hole, thus affecting the overall production safety factor. Utility Model Content

[0006] The purpose of this utility model is to provide a simple insertable lifting anti-detachment plate device to solve the problems of low safety factor of existing lifting bar structure design, easy detachment of lifting bar under mold lifting force, potential safety hazards, and complex, not simple enough structure, high production cost, complicated installation and use of traditional lifting bar anti-detachment technology.

[0007] To address this, a simple insertable lifting anti-detachment plate device is proposed, comprising an anti-detachment plate installed on a lifting rod, wherein two symmetrical mounting holes are formed on the surface of the anti-detachment plate, the mounting holes being of an oblong shape, the mounting holes being used to allow bolts to pass through, and the bolts reciprocating within the mounting holes;

[0008] A through hole is formed between the two mounting holes, and the diameter of the through hole is clearance-fitted with the maximum outer diameter of the lifting rod.

[0009] A spring mounting plate is provided on the surface corresponding to the mounting hole at one end of the anti-detachment plate, and the spring mounting plate is provided with bolt holes for bolts to pass through. The bolts pass through both the bolt holes and the mounting holes to fix the spring mounting plate and the anti-detachment plate together.

[0010] The anti-detachment plate has a raised end at its upper and lower ends. The raised end is formed by protruding outward relative to the surface of the anti-detachment plate. The raised end is connected to the spring mounting plate by a spring.

[0011] The advantages are: In this utility model, the spring mounting plate and the anti-detachment plate are fixed together by bolts. At the same time, the bolts also fix the anti-detachment plate to the surface of the lifting mold where the lifting rod mounting end is located. Furthermore, the anti-detachment plate can move up and down on the fixed bolts through the waist-shaped mounting hole, rather than being firmly fixed to the mold surface.

[0012] The through hole in the middle of the anti-detachment plate is fitted with the lifting bar with a clearance fit to facilitate the installation and removal of the lifting bar.

[0013] During assembly and use, the spring connects the protruding end of the anti-detachment plate to the spring mounting plate. Initially, the spring is in a contracted state when no force is applied, while the protruding end of the anti-detachment plate and the spring mounting plate are mutually pulling. At this time, the bolt fixed on the spring mounting plate is the point of force application. The anti-detachment plate moves upward along the waist-shaped mounting hole under the pulling force of the spring. At the same time, the through hole also moves upward and interlocks with the limiting groove of the already installed lifting rod, thus realizing the anti-detachment locking function of the lifting rod of this utility model.

[0014] Conversely, when disassembly is required, pressing down on the anti-detachment plate stretches the spring, resets the through hole, and aligns it with the center of the lifting rod again, allowing the lifting rod to be pulled out for easy disassembly. The protruding end provides a force-bearing area when the anti-detachment plate is pressed, facilitating disassembly and installation.

[0015] A further improvement is that the bolts fix the anti-detachment plate to the mold surface at the lifting rod mounting end through the mounting holes, and the anti-detachment plate can move up and down on the fixed bolts through the upper and lower waist-shaped mounting holes.

[0016] The effect is that the movable anti-detachment plate enables the easy disassembly and installation of this utility model.

[0017] A further improvement is that the bolt is also equipped with a matching washer during assembly.

[0018] The benefits are: the gasket can reduce bolt wear and extend the overall service life, while also preventing the anti-detachment plate from falling off the fixing bolt.

[0019] A further improvement is that the anti-detachment plate structure is rhomboid, and the left and right sides of the rhomboid are rounded.

[0020] The effect is that the diamond-shaped anti-detachment plate makes it easy to identify the main direction during installation and use.

[0021] A further improvement is that two lifting lugs are formed on the surface of the spring mounting plate. The structure is that the semi-circular protrusions at the left and right ends of the spring mounting plate are raised outward relative to the surface of the spring mounting plate to form two lifting lugs.

[0022] The effect is that the lifting lugs are designed to facilitate the installation of the spring, to connect the spring mounting plate and the anti-slip plate via the spring, and to apply the shock absorption and locking effect of the spring to the anti-slip plate.

[0023] A further improvement is that the lugs on the spring mounting plate are connected to the protruding end at the upper end of the anti-slip plate via springs.

[0024] The benefits are as follows: the lugs on the spring mounting plate are connected to the protruding end at the top of the anti-slip plate via springs, which takes up less space, makes installation and disassembly more convenient, and greatly improves the user experience.

[0025] A further improvement is that the springs are in pairs.

[0026] The effect is that a pair of springs is sufficient to absorb the instantaneous impact force during the hoisting process (such as crane start-up / sudden stop), reducing the rigid impact on the mold and lifting equipment, thereby avoiding damage to the utility model structure. Beneficial effects

[0027] This utility model is a simple insert-type lifting anti-detachment clamping device mainly composed of an anti-detachment plate, a spring mounting plate, a spring, and bolts. In use, downward pressure is applied to the anti-detachment plate, and the through hole in the center of the anti-detachment plate coincides with the center of the lifting rod, allowing the lifting rod to be easily pulled out for simple disassembly. During installation, first press down on the anti-detachment plate, then push the lifting rod into the mold fixing position. After pushing it into place, release the anti-detachment plate; the through hole moves upward and engages with the limiting groove of the lifting rod, thus achieving a locking and anti-detachment effect. The operation is simple and the anti-detachment effect is excellent. This utility model provides a more stable anti-detachment effect, ensuring that the mold will not accidentally fall off during the lifting process, resulting in a high overall safety factor. Furthermore, this utility model is ingeniously designed, has a simple structure, low manufacturing cost, and is easy to use, making it suitable for widespread adoption. Attached Figure Description
