Description

Technical Field

[0001] This utility model relates to the technical field of rope force distribution devices, specifically a detachable perforated force distribution plate for ropes. Background Technology

[0002] In scenarios involving rope operations such as lifting, traction, and hoisting, to prevent a single rope from breaking due to excessive stress, it is often necessary to distribute the tension across multiple ropes using a force-sharing device. Currently, most commonly used rope force-sharing structures are one-piece designs, which present problems such as difficult assembly and disassembly, inconvenient maintenance, and the need to replace the entire structure when a component fails, increasing operating costs.

[0003] Meanwhile, the existing force-sharing devices have simple force-sharing plate structures and unreasonable mounting frame layouts, resulting in uneven rope stress and significant local stress concentration. This easily leads to force-sharing plate deformation or rope wear, affecting operational safety and equipment lifespan. In addition, traditional force-sharing plates have a fixed and limited number of rope connection holes, making it difficult to adapt to the force-sharing requirements of multiple ropes, thus limiting their applicability.

[0004] In addition, the connecting parts of existing force distribution devices are mostly fixed with a single thread, which is prone to loosening under vibration or long-term stress, resulting in a decrease in the stability of the force distribution and posing a safety hazard. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a detachable multi-hole force-sharing plate for ropes that offers sensitive and accurate monitoring.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a detachable perforated force-shaping plate for ropes, comprising a first perforated force-shaping plate and a second perforated force-shaping plate, and a long rod, wherein the long rod passes through the mounting holes of the first perforated force-shaping plate and the second perforated force-shaping plate;

[0009] One end of the long rod is sequentially fitted with a central pressure spring, a central rod, and a knob. The knob is threaded to one end of the central rod. One end of the central pressure spring is fitted onto the long rod and abuts against the second multi-hole force-sharing plate. The other end of the central pressure spring is fitted onto the central rod.

[0010] One end of the long rod is connected to the second porous force-sharing plate through a perforated pin, and the long rod is connected to the central rod through a cotter pin.

[0011] Preferably, the first porous force-shaping plate is provided with at least three first mounting brackets, and the second porous force-shaping plate is provided with at least four second mounting brackets, with the three first mounting brackets located at the gaps between the four second mounting brackets, and the mounting holes are provided on the first mounting brackets and the second mounting brackets.

[0012] More preferably, the knob and the center rod are connected by a set screw.

[0013] Preferably, a compression spring is fitted onto the set screw.

[0014] Preferably, both the first and second porous force-sharing plates are five-hole force-sharing plates.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a detachable perforated force-sharing plate for ropes, which has the following advantages:

[0017] First, the long rod passes through the mounting holes of the first and second multi-hole force-shaping plates, and together with the intermediate pressure spring, center rod and knob, it realizes detachable assembly, which greatly facilitates installation and subsequent maintenance and significantly shortens the operation time.

[0018] Secondly, at least three first mounting brackets on the first porous force-shaping plate are located in the gaps between at least four second mounting brackets on the second porous force-shaping plate. This arrangement makes the rope more evenly distributed on the force-shaping plate. When the rope is under force, the tension can be more evenly distributed, avoiding excessive local stress, significantly improving the stability of the force-shaping plate, and extending the service life of the force-shaping plate.

[0019] Furthermore, the knob and the center rod are connected by a set screw, and a compression spring is fitted on the set screw. This not only enhances the stability of the connection between the knob and the center rod and prevents loosening due to vibration and other factors, but the compression spring can also buffer vibration and impact, further improving the reliability and durability of the connecting parts.

[0020] Finally, the first and second multi-hole force-sharing plates adopt a five-hole design, which can accommodate the force-sharing needs of up to five ropes. This not only copes with complex multi-rope tension distribution scenarios, but also ensures the simplicity of the force-sharing plate structure and ease of operation. It achieves a good balance between force-sharing capacity and ease of use, effectively solving the problems of inconvenient assembly, poor force-sharing effect, and insufficient applicability of traditional force-sharing structures.

[0024] 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.

[0025] Please see Figure 1-2 The present invention is a detachable multi-hole force-sharing plate for ropes, including a first multi-hole force-sharing plate 1 and a second multi-hole force-sharing plate 2, and a long rod 3, wherein the long rod 3 is inserted into the mounting holes 12 of the first multi-hole force-sharing plate 1 and the second multi-hole force-sharing plate 2;

[0026] One end of the long rod 3 is sequentially fitted with a medium pressure spring 5, a central rod 4 and a knob 6. The knob 6 is threadedly connected to one end of the central rod 4. One end of the medium pressure spring 5 is fitted on the long rod 3 and abuts against the second porous force-sharing plate 2. The other end of the medium pressure spring 5 is fitted on the central rod 4.

[0027] One end of the long rod 3 is connected to the second porous force-sharing plate 2 through a flow pin 10, and the long rod 3 is connected to the central rod 4 through a cotter pin 7.

[0028] The long rod 3 passes through the mounting holes 12 of the first porous force-shaping plate 1 and the second porous force-shaping plate 2, providing support and connection for the entire force-shaping plate. A central pressure spring 5, a central rod 4, and a knob 6 are sequentially fitted onto one end of the long rod 3, with the knob 6 threadedly connected to the central rod 4. When the knob 6 is tightened, it pushes the central rod 4, thereby compressing the central pressure spring 5. One end of the central pressure spring 5 abuts against the second porous force-shaping plate 2. Under the action of compression, the first porous force-shaping plate 1 and the second porous force-shaping plate 2 are tightly fitted together, ensuring the stability of the overall structure of the force-shaping plate. Simultaneously, one end of the long rod 3 is connected to the second porous force-shaping plate 2 via a stud pin 10, and the long rod 3 is connected to the central rod 4 via a cotter pin 7, further fixing the relative positions of the components and preventing relative displacement of the components of the force-shaping plate when the rope is under stress, ensuring the reliability of the force-shaping process. When the rope is connected to the two force-shaping plates, the tension of the rope is transmitted through the mounting bracket and force-shaping holes of the force-shaping plates. By utilizing the structural strength of components such as the long rod 3 and the central rod 4, the larger tension of the single rope is distributed to multiple ropes, thus achieving the force-sharing function.

[0029] At least three first mounting brackets 13 on the first porous force-shaping plate 1 are located at the gaps between at least four second mounting brackets 11 on the second porous force-shaping plate 2, and mounting holes 12 are provided on these mounting brackets. This layout ensures a compact overall structure of the force-shaping plates while making the rope distribution on the first porous force-shaping plate 1 and the second porous force-shaping plate 2 more uniform. When the rope is under tension, the tension can be more evenly distributed to each mounting bracket, avoiding excessive stress on local mounting brackets, improving the stability of the force distribution and the service life of the force-shaping plates.

[0030] The knob 6 and the center rod 4 are connected by a set screw 9, which restricts the relative rotation between the knob 6 and the center rod 4. During the operation of the force distribution plate, even if affected by vibrations from rope tension, the stability of the threaded connection between the knob 6 and the center rod 4 is ensured, preventing the knob 6 from loosening. This ensures that the clamping force of the central pressure spring 5 on the first porous force distribution plate 1 and the second porous force distribution plate 2 is always maintained, thus maintaining the structural stability of the force distribution plate.

[0031] A compression spring 8 is fitted onto the set screw 9. When the set screw 9 secures the knob 6 and the center rod 4, the compression spring 8 is compressed, generating an elastic preload. This preload further enhances the tightness of the connection between the knob 6 and the center rod 4. At the same time, the compression spring 8 can buffer the impact of vibration on the connection, reduce the possibility of the set screw 9 loosening due to vibration, and extend the service life of the connecting parts.

[0032] Both the first multi-hole force-sharing plate 1 and the second multi-hole force-sharing plate 2 adopt a five-hole design, which can accommodate the force distribution requirements of up to five ropes. Compared with force-sharing plates with fewer holes, it can handle more complex multi-rope tension distribution scenarios; compared with force-sharing plates with too many holes, it can ensure the simplicity of the force-sharing plate structure and the convenience of operation, thus achieving a balance between force distribution capacity and ease of use.

[0033] Detailed Workflow

[0034] Assembly preparation: Prepare the following components: first multi-hole force distribution plate 1, second multi-hole force distribution plate 2, long rod 3, medium pressure spring 5, center rod 4, knob 6, flow pin 10, cotter pin 7, set screw 9, compression spring 8, etc.

[0035] Inserting long rod 3: Insert long rod 3 through the mounting holes 12 of the second porous force-shaping plate 2 and the first porous force-shaping plate 1 in sequence.

[0036] Install the elastic and connecting components: Slide the intermediate pressure spring 5 onto one end of the long rod 3, then slide the center rod 4 onto the long rod 3, so that the other end of the intermediate pressure spring 5 is on the center rod 4; connect the knob 6 to one end of the center rod 4 by thread, then slide the compression spring 8 onto the set screw 9, and then use the set screw 9 to pass through the knob 6 and the center rod 4 to achieve a fixed connection between the two; use the stud pin 10 to connect one end of the long rod 3 to the second multi-hole force distribution plate 2, and use the cotter pin 7 to connect the long rod 3 to the center rod 4.

[0037] Rope connection: Based on the actual number of ropes, connect multiple ropes to the force-sharing holes of the first multi-hole force-sharing plate 1 and the second multi-hole force-sharing plate 2 respectively.

[0038] Force distribution operation: When the rope is under tension, the force is transmitted to the mounting brackets of the first porous force distribution plate 1 and the second porous force distribution plate 2. Through the support of components such as the long rod 3 and the central rod 4, and the clamping action of the central pressure spring 5, the large tension of the single rope is distributed into smaller tensions of multiple ropes, completing the force distribution operation. During this process, components such as the set screw 9 and the pressure spring 8 ensure the stable connection between the knob 6 and the central rod 4, and the layout of the first and second mounting brackets 11 makes the tension distribution more even.

[0039] Disassembly and maintenance: After the work is completed, remove the cotter pin 7, stud pin 10, set screw 9 and other parts in sequence, loosen the knob 6 to release the compression force of the central pressure spring 5, and then take out the long rod 3, center rod 4 and other parts, and inspect, maintain or replace each part of the force distribution plate.
