Description

Technical Field

[0001] This utility model relates to the technical field of high-strength rope and net connection devices, and in particular to a high-strength rope and net connection device. Background Technology

[0002] In aerospace, marine engineering, and construction, rope net systems serve as key components for load-bearing, protection, and connection. The reliability of their connection with related structures directly affects system safety. With the increasing complexity of engineering applications, higher requirements are placed on the strength, wear resistance, and impact resistance of rope net connection devices. Although various rope net connection schemes exist in the current technology, there is still room for optimization in terms of the stability of multi-rope coordinated force, buffering performance under dynamic loads, and ease of maintenance during long-term use, in order to meet the needs of modern engineering for high-strength and high-reliability connection devices.

[0003] Existing high-strength rope net connection devices mostly adopt a one-way clamping structure, which directly squeezes the rope with bolts or buckles to achieve fixation. In actual use, when faced with dynamic loads, the one-way clamping force cannot automatically adjust with the load changes, which may lead to rope slippage or loosening of connecting parts, posing a safety hazard. Therefore, we propose a high-strength rope net connection device. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength rope net connection device to solve the problem mentioned in the background art, which mostly adopts a unidirectional clamping structure and achieves fixation by directly squeezing the rope with bolts or buckles. In actual use, when faced with dynamic loads, the unidirectional clamping force cannot be automatically adjusted with the load changes, which may lead to rope slippage or loosening of connecting parts, posing a safety hazard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength rope net connecting device, including a connecting seat, the front of which has two rope grooves, each containing a rope; a locking assembly is provided inside the connecting seat, the locking assembly including a torsion block, a spring, and an arc-shaped block; the torsion block is connected to the locking block via a screw; a slot is provided on the upper inner wall of the rope groove; the outer wall of the screw is threadedly connected to the top inner wall of the connecting seat; and the outer wall of the locking block is slidably connected to the inner wall of the slot.

[0006] As a preferred embodiment, the upper end of the screw is fixedly connected to the bottom of the torsion block, the lower end of the screw is rotatably connected to the top of the locking block, and the lower surface of the locking block is in contact with the upper surface of the rope.

[0007] As a preferred embodiment, the lower inner wall of the rope groove is provided with a groove located directly below the slot, the lower end of the spring is fixedly connected to the inner bottom wall of the groove, and the upper end of the spring is fixedly connected to the bottom surface of the arc-shaped block.

[0008] As a preferred embodiment, the upper surface of the arc-shaped block is in contact with the lower surface of the rope, and the outer wall of the arc-shaped block is slidably connected to the inner wall of the groove.

[0009] As a preferred embodiment, the right end of the rope groove is provided with an anti-wear component, the anti-wear component includes an arc-shaped anti-wear sleeve, an internal thread is provided on the inner wall of the right side of the rope groove, and an external thread is provided on the outer wall of the arc-shaped anti-wear sleeve.

[0010] As a preferred embodiment, the internal thread is threadedly connected to the external thread, and an elastic buffer anti-wear pad is fixedly connected to the inner wall of the arc-shaped anti-wear sleeve, with the inner wall of the elastic buffer anti-wear pad fitting against the outer wall of the rope.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By rotating the locking assembly, the operator drives the screw to rotate, pushing the locking block down along the groove and pressing the upper surface of the rope. When the rope is compressed, it squeezes the arc-shaped block, compressing the spring in the groove. The spring generates an upward reaction force, pushing the arc-shaped block to press against the lower surface of the rope, forming a bidirectional clamping structure that fixes the rope in the rope groove. This structure achieves dynamic adjustment of the clamping force through spring deformation. When the rope is under load, the spring is further compressed, the reaction force increases, and the clamping force is strengthened accordingly, effectively preventing the rope from slipping. Compared with the traditional unidirectional clamping structure, this device improves the strength and reliability of the connection through bidirectional clamping and load adaptive mechanism.

[0013] With its anti-abrasion components, the arc-shaped inner wall of the arc-shaped anti-abrasion sleeve matches the contour of the rope, preventing direct contact between the rope and the metal inner wall of the rope groove and reducing frictional loss. The elastic buffer anti-abrasion pad is fixed to the inner wall of the arc-shaped anti-abrasion sleeve and is made of elastic materials such as rubber, which fits tightly against the outer wall of the rope. When the rope is subjected to vibration or impact, the elastic buffer anti-abrasion pad absorbs energy through deformation, reducing rigid collisions between the rope and the arc-shaped anti-abrasion sleeve. At the same time, the combination of external and internal threads allows for convenient disassembly, assembly, and maintenance of the arc-shaped anti-abrasion sleeve. Attached Figure Description

[0021] 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.

[0022] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 4 and appendix Figure 5 A high-strength rope net connection device includes a connecting seat 1. The front of the connecting seat 1 has two rope grooves 2, and ropes 3 are arranged inside the two rope grooves 2. The connecting seat 1 has a locking assembly 4 inside, which includes a torsion block 402, a spring 406, and an arc block 407. The torsion block 402 is connected to a locking block 404 through a screw 403. The upper inner wall of the rope groove 2 has a slot 401. The outer wall of the screw 403 is threaded to the top inner wall of the connecting seat 1. The outer wall of the locking block 404 is slidably connected to the inner wall of the slot 401. The upper end of the screw 403 is fixedly connected to the bottom of the torsion block 402, and the lower end of the screw 403 is rotatably connected to the top of the locking block 404. The lower surface of the locking block 404 is in contact with the upper surface of the rope 3.

[0023] The connecting seat 1 is made of titanium alloy and is forged in one piece, which can improve the overall strength of the device and withstand a large load. The rope 3, as the object of connection and load-bearing, is used to transmit tension and load and is an important part of the entire rope net system.

[0024] The lower inner wall of the rope groove 2 is provided with a groove 405 located directly below the slot 401. The lower end of the spring 406 is fixedly connected to the inner bottom wall of the groove 405, and the upper end of the spring 406 is fixedly connected to the bottom surface of the arc block 407. The upper surface of the arc block 407 is in contact with the lower surface of the rope 3, and the outer wall of the arc block 407 is slidably connected to the inner wall of the groove 405.

[0025] The torsion block 402 provides a point of force for the operator. By rotating the torsion block 402, the screw 403 is driven to rotate, thereby adjusting the position of the locking block 404. Its design facilitates manual operation and improves the ease of use of the device.

[0026] Specifically, through the locking component 4, the operator rotates the torsion block 402, driving the screw 403 to rotate and pushing the locking block 404 down along the slot 401, pressing the upper surface of the rope 3. After being pressed, the rope 3 squeezes the arc-shaped block 407, compressing the spring 406 in the groove 405. The spring 406 generates an upward reaction force, pushing the arc-shaped block 407 to press against the lower surface of the rope 3, forming a bidirectional clamping structure. This structure achieves dynamic adjustment of the clamping force through the deformation of the spring 406: when the rope 3 bears a load, the spring 406 is further compressed, the reaction force increases, and the clamping force is strengthened accordingly, effectively preventing the rope 3 from slipping. Compared with the traditional unidirectional pressing structure, this device improves the strength and reliability of the connection through bidirectional clamping and load adaptive mechanism.

[0027] Please see the appendix Figure 1 - Appendix Figure 3 and appendix Figure 6 The right end of the rope groove 2 is provided with an anti-wear component 5, which includes an arc-shaped anti-wear sleeve 502. An internal thread 501 is provided on the inner wall of the right side of the rope groove 2, and an external thread 504 is provided on the outer wall of the arc-shaped anti-wear sleeve 502. The internal thread 501 and the external thread 504 are threadedly connected. An elastic buffer anti-wear pad 503 is fixedly connected to the inner wall of the arc-shaped anti-wear sleeve 502. The inner wall of the elastic buffer anti-wear pad 503 is in contact with the outer wall of the rope 3.

[0028] The internal thread 501 is formed on the inner wall of the right side of the rope groove 2, and it cooperates with the external thread 504 of the arc-shaped anti-wear sleeve 502 to realize the detachable connection of the arc-shaped anti-wear sleeve 502. This threaded connection method facilitates the installation and replacement of the arc-shaped anti-wear sleeve 502. When the arc-shaped anti-wear sleeve 502 is severely worn, it is not necessary to replace the entire connecting seat 1.

[0029] Specifically, through the anti-wear component 5, the arc-shaped anti-wear sleeve 502's arc-shaped inner wall matches the contour of the rope 3, avoiding direct contact between the rope 3 and the metal inner wall of the rope groove 2, thus reducing frictional loss. The elastic buffer anti-wear pad 503 is fixed to the inner wall of the arc-shaped anti-wear sleeve 502, and is made of elastic materials such as rubber, fitting snugly against the outer wall of the rope 3. When the rope 3 is subjected to vibration or impact, the elastic buffer anti-wear pad 503 absorbs energy through deformation, reducing rigid collisions between the rope 3 and the arc-shaped anti-wear sleeve 502. The external thread 504 and the internal thread 501 cooperate to achieve convenient disassembly, assembly, and maintenance of the arc-shaped anti-wear sleeve 502.

[0030] The working principle of this utility model is as follows: This utility model is a high-strength rope net connection device. First, the worker places the rope 3 in the rope groove 2 of the connecting seat 1, ensuring that the rope 3 is located between the locking block 404 and the arc-shaped block 407. Then, the worker manually rotates the torsion block 402, driving the screw 403 to rotate. Since the outer wall of the screw 403 is threadedly connected to the inner wall of the top of the connecting seat 1, when the screw 403 rotates, it pushes the locking block 404 to slide downward along the slot 401 until the lower surface of the locking block 404 presses against the upper surface of the rope 3. At this time, the rope 3 is compressed and presses downward against the arc-shaped block 407. The arc-shaped block 407 compresses the spring 406 in the groove 405. The spring 406 generates an upward reaction force, pushing the upper surface of the arc-shaped block 407 to press against the lower surface of the rope 3, forming a two-way clamping structure of upper pressure and lower push, fixing the rope 3 in the rope groove 2. When the rope 3 bears a load, the tension is transmitted to the locking block 404. 04 and the arc-shaped block 407, spring 406 are further compressed, the reaction force increases with the increase of load, automatically adjust the clamping force to prevent rope 3 from slipping. Next, the operator screws the arc-shaped anti-wear sleeve 502 into the inner thread 501 on the right side of the inner wall of the rope groove 2 through the external thread 504 on the outer wall, and fixes it to the right end of the rope groove 2, so that the inner wall of the elastic buffer anti-wear pad 503 is in contact with the outer wall of the rope 3. The direct contact between the rope 3 and the metal inner wall of the rope groove 2 is isolated by the arc-shaped anti-wear sleeve 502. Its arc-shaped inner wall matches the contour of the rope 3, reducing sliding friction loss. When the rope 3 is subjected to vibration or impact, the elastic buffer anti-wear pad 503 absorbs energy through deformation, reduces the rigid collision between the rope 3 and the arc-shaped anti-wear sleeve 502, and protects the surface of the rope 3. When the arc-shaped anti-wear sleeve 502 or the elastic buffer anti-wear pad 503 is worn, the arc-shaped anti-wear sleeve 502 can be directly unscrewed for replacement without disassembling the connecting seat 1, improving maintenance efficiency.
