Description

Technical Field

[0001] This utility model relates to the field of force-shaping plate technology, specifically, to a force-shaping plate. Background Technology

[0002] In modern industrial operations, the force distribution plate, as a key component for force transmission and distribution, directly impacts operational safety and efficiency. In existing technologies, some force distribution plates, when applied to lifting scenarios, frequently experience loosening or displacement due to design flaws in the fit between the mandrel assembly and the plate. Specifically, traditional mandrel assemblies often employ simple plug-in connections or interference fits, lacking multi-dimensional locking mechanisms. When the lifting load undergoes dynamic changes, such as the impact force during lifting or wind vibration, the mandrel assembly is prone to axial movement or radial displacement within the mandrel hole. For example, in a bridge construction project, the force distribution plate, where the mandrel base rod and plate relied solely on an interference fit, experienced a gap widening from 0.1mm to 0.5mm within three months under continuous vibration loads. This resulted in force imbalance in the force distribution plate, leading to a lifting rope misalignment accident. Simultaneously, due to the loosening of the mandrel assembly, the load cannot be evenly distributed across the plate's stress points, causing localized stress concentration. In a case involving heavy machinery, a 2cm long crack appeared on the edge of the force distribution plate due to long-term uneven stress. Tests showed that the stress value at the crack reached 82% of the material's yield strength, posing a serious safety hazard.

[0003] Furthermore, existing force distribution plates often face the challenge of cumbersome operation during disassembly and maintenance. The disassembly structure of existing force distribution plates is complex; for example, some products use a multi-bolt concealed fixing method, requiring the use of a special wrench to loosen 12 bolts one by one during disassembly, with a single maintenance session taking up to 4 hours. Moreover, the bolt holes are prone to stripping due to repeated disassembly. Maintenance records from a shipyard show that the average annual maintenance cost of traditional force distribution plates accounts for 18% of the total equipment investment, far exceeding the industry's reasonable level of 5%-8%. Due to the inadequate design of the connection structure between the spindle assembly and the plate body, disassembly requires complex operations using multiple tools, and may even necessitate the disassembly of the entire force distribution plate structure. This not only consumes a significant amount of time and manpower but also easily damages components during disassembly, failing to meet the practical needs for convenient maintenance of force distribution plates. This is also one of the important factors limiting the widespread application of existing force distribution plates. Currently, no effective solution has been proposed that simultaneously addresses these problems in related technologies, resolving stability, maintainability, and force balance.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a force-sharing plate to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A force-sharing plate includes: a plate body, wherein a through mandrel hole is provided on one side of the plate body, a mandrel assembly is movably inserted into the mandrel hole, and two closed lifting grooves are formed between the mandrel assembly and the plate body;

[0008] The mandrel assembly includes: a mandrel base rod, a bushing movably sleeved at the end of the mandrel base rod, a rotating rod movably inserted inside the bushing, a ring-shaped locking block at the end of the rotating rod and inside the bushing, the locking block being adapted to a groove provided inside the bushing, and the other end of the rotating rod movably inserted inside the mandrel base rod, and a spring being provided between the rotating rod and the mandrel base rod;

[0009] The other end of the mandrel base rod is fixedly provided with a clamp, which is adapted to the positioning groove provided in the mandrel hole.

[0010] Furthermore, the plate body is provided with several lifting holes.

[0011] Furthermore, a pin is fixedly provided inside the plate, and the end of the pin extends into the outermost positioning groove.

[0012] Furthermore, the outer circumferential surface of the bushing is provided with anti-slip texture, which is an annular ridge or a grid-like protrusion structure.

[0013] Furthermore, both the locking block and the groove are fan-shaped structures, the locking blocks are evenly distributed circumferentially along the end face of the rotating rod, and the groove is adapted to the locking block.

[0014] Furthermore, the spring is sleeved on the rotating rod, and the end of the spring abuts against the end of the spindle base rod.

[0015] Furthermore, the mandrel base rod is provided with a limiting groove, and the end of the rotating rod is inserted into the mandrel base rod and slides along the limiting groove.

[0016] The beneficial effects of this utility model are:

[0017] This invention significantly improves the stability and reliability of the force distribution plate in practical applications. The mandrel assembly and the plate body employ a three-dimensional mating structure: radial limiting with clamps and positioning grooves, circumferential locking with clamps and grooves, and axial pre-tensioning with springs. This changes the traditional single-fixation mode of plug-in connection or interference fit. This design creates a closed mechanical locking system within the plate body, effectively resisting axial movement and radial offset caused by dynamic loads during hoisting, and avoiding stress imbalance problems caused by component loosening.

[0018] Furthermore, disassembly is simple: just press the rotating rod and rotate the bushing to release the component lock, allowing the spindle assembly to be easily removed without the need for complex tools or disassembling the entire structure, significantly simplifying the maintenance process. This design avoids the cumbersome operation and easy damage to parts associated with traditional bolt fixing methods, effectively shortening maintenance time and reducing labor costs. In addition, the enclosed lifting slot structure allows the load to be evenly distributed across the plate, optimizing the force transmission path and reducing localized stress concentration.

[0029] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0030] According to an embodiment of the present invention, a force-sharing plate is provided.

[0031] like Figure 1-6 As shown, the force-shaping plate according to an embodiment of the present utility model includes: a plate body 1, a through mandrel hole 2 on one side of the plate body 1, a mandrel assembly 3 movably inserted into the mandrel hole 2, and two closed lifting grooves 4 formed between the mandrel assembly 3 and the plate body 1;

[0032] The mandrel assembly 3 includes: a mandrel base rod 31, a bushing 32 movably sleeved at the end of the mandrel base rod 31, a rotating rod 33 movably inserted inside the bushing 32, a ring-shaped locking block 34 located at the end of the rotating rod 33 inside the bushing 32, the locking block 34 being adapted to a groove 35 in the bushing 32, and the other end of the rotating rod 33 being movably inserted inside the mandrel base rod 31, and a spring 36 being provided between the rotating rod 33 and the mandrel base rod 31; a locking member 37 is fixedly provided at the other end of the mandrel base rod 31, and the locking member 37 is adapted to a positioning groove 38 in the mandrel hole 2.

[0033] In addition, the plate body 1 has several lifting holes 5. A pin 6 is fixedly installed inside the plate body 1, with the end of the pin 6 extending into the outermost positioning groove 38. The outer circumferential surface of the bushing 32 is provided with anti-slip texture 7, which is an annular ridge or a grid-like raised structure. Both the locking block 34 and the groove 35 are fan-shaped structures. The locking block 34 is evenly distributed circumferentially along the end face of the rotating rod 33, and the groove 35 is adapted to the locking block 34. The spring 36 is sleeved on the rotating rod 33, and the end of the spring 36 abuts against the end of the spindle base rod 31. The spindle base rod 31 is provided with a limiting slide groove, and the end of the rotating rod 33 is inserted into the spindle base rod 31 and slides along the limiting slide groove.

[0034] Using the above method, during installation, the mandrel assembly 3 is inserted into the mandrel hole 2. The retainer 37 at the end of the mandrel base rod 31 is adapted to the positioning groove 38 in the mandrel hole 2, achieving initial positioning of the mandrel assembly 3 and the plate 1. Then, pressing the rotating rod 33 causes it to slide in the limiting groove in the mandrel base rod 31, so that the retainer 34 at the end of the rotating rod 33 engages with the groove 35 in the bushing 32. At this time, the spring 36 is compressed, thereby rotating the bushing 32, which in turn rotates the rotating rod 33 and the mandrel base rod 31, thus disengaging the retainer 37 of the mandrel assembly 3 from the positioning groove 38, causing the retainer 37 to fall into the limiting groove 39, thereby firmly fixing the mandrel base rod 31 to the body 1.

[0035] During disassembly, press the rotating rod 33 and rotate the bushing 32 in the opposite direction to rotate the rotating rod 33 and the spindle base rod 31 together, so that the locking piece 37 at the end of the spindle base rod 31 matches the positioning groove 38 at an appropriate angle, and the spindle assembly 3 can be pulled out from the spindle hole 2 along one side. The pin 6 is used to further fix the spindle assembly 3 to prevent it from falling off during use.

[0036] In addition, during the hoisting process, the hoisting slot 4 is used to place the hoisting ropes, and the hoisting hole 5 in the plate 1 can also be used for hoisting. The pin 6 is used to disassemble the spindle base rod 31. When disassembling to the pin 6, it will not be pulled outward. The purpose of this design is that when disassembling the rope lock in the hoisting slot 4 on the other side, it is not necessary to completely disassemble the spindle base rod 31. The anti-slip texture 7 on the outer circumference of the bushing 32 increases the friction of the bushing 32 and improves the rotation efficiency.

[0037] In summary, by utilizing the above-mentioned technical solution of this utility model, the stability and reliability of the force distribution plate in practical applications are significantly improved. The mandrel assembly and the plate body employ a three-dimensional mating structure: radial limiting with clamps and positioning grooves, circumferential locking with clamping blocks and grooves, and axial pre-tensioning with springs. This changes the traditional single fixing mode of plug-in connection or interference fit. This design creates a closed mechanical locking system within the plate body, effectively resisting axial movement and radial offset caused by dynamic loads during hoisting, and avoiding force imbalance problems caused by component loosening.

[0038] Furthermore, disassembly is simple: just press the rotating rod and rotate the bushing to release the component lock, allowing the spindle assembly to be easily removed without the need for complex tools or disassembling the entire structure, significantly simplifying the maintenance process. This design avoids the cumbersome operation and easy damage to parts associated with traditional bolt fixing methods, effectively shortening maintenance time and reducing labor costs. In addition, the enclosed lifting slot structure allows the load to be evenly distributed across the plate, optimizing the force transmission path and reducing localized stress concentration.
