A ship's arresting cable toughness testing apparatus

Abstract

This utility model discloses a marine arresting cable toughness testing device, including a platform with two protective shells mounted on top. Hydraulic rods are installed inside the protective shells, and positioning seats are mounted on the output ends of the hydraulic rods. The positioning seats are slidably connected to the top of the platform, and positioning components are mounted on top of the positioning seats. A movable shell assembly is installed inside the protective shells. This marine arresting cable toughness testing device achieves efficient clamping of the arresting cable through a unique design of the positioning and movable shell assemblies. During positioning, only two operators need to simultaneously push the guide plate to close the U-shaped frame. During the closing process, the guide plate applies pressure to the square rod through pulleys, causing the clamping blocks to slide down and securely clamp both ends of the sample arresting cable. Unlike traditional testing methods that use multiple bolts to fix the clamping blocks to prevent upward movement, this greatly simplifies the clamping and releasing operation process, saves time and manpower, and improves testing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of rope testing technology, and in particular to a marine arresting cable toughness testing device. Background Technology

[0002] Marine arresting cables, specifically referring to aircraft carrier arresting cables in aircraft carrier scenarios, are crucial devices used to absorb the kinetic energy of landing aircraft and shorten the landing taxi distance. They are considered the "lifeline" of carrier-based aircraft and are typically composed of high-strength steel wires with extremely high tensile strength. Each arresting cable generally consists of 6 strands of special steel wire rope, and each strand is made up of 12 thicker main steel wires, 12 medium-sized steel wires, and 6 thin steel wires arranged in a triangular shape twisted together.

[0003] The applicant found through a search that steel wire ropes in the prior art need to undergo toughness testing during production. Traditional testing methods mostly involve fixing both ends of the rope with two sets of movable positioning structures to perform tensile testing. For example, the steel wire rope lock testing device disclosed in patent number 202020436653.5 is designed in this way.

[0004] However, in practical applications, it has been found that the above solution has certain shortcomings. When positioning, it is necessary to press down on both ends of the sample rope with a pressure block and fix it with multiple bolts to prevent the pressure block from moving upward. This makes the clamping and unclamping operations very complicated, time-consuming and labor-intensive. In addition, the movable door of the above solution does not have a certain limiting structure after closing, resulting in insufficient protection performance.

[0005] Therefore, the applicant proposes a marine arresting cable toughness testing device to solve the problem. Utility Model Content

[0006] This invention provides a marine arresting cable toughness testing device, which solves the problems mentioned in the background.

[0007] To solve the above technical problems, this utility model provides a marine arresting cable toughness testing device, including an equipment platform, two protective shells installed on the top of the equipment platform, and hydraulic rods installed inside the protective shells. The output end of the hydraulic rods is equipped with a positioning seat, the positioning seat is slidably connected to the top of the equipment platform, and a positioning component is installed on the top of the positioning seat. A movable shell component is installed inside the protective shell.

[0008] The positioning component includes a U-shaped frame fixed to the top of the positioning seat, a clamping block slidably installed on the inner side of the U-shaped frame, corresponding arc-shaped grooves provided at the bottom of the clamping block and the top of the positioning seat, two square rods passing through the U-shaped frame fixed to the top of the clamping block, pulleys installed on the top of the square rods, and a return spring connected to the groove on the top of the clamping block and the U-shaped frame.

[0009] The square rod moves up and down through the closing operation of the movable shell assembly.

[0010] Preferably, the movable shell assembly includes a U-shaped frame slidably installed on the inner wall of the protective shell. The U-shaped frame has a three-section design and an integrally installed guide plate. The guide plate extends out from one end of the protective shell, and the guide plate corresponds to the position of the pulley. The end of the guide plate facing the pulley has an arc surface design.

[0011] Preferably, the U-shaped frame has openings on both sides, and tempered glass is installed in the openings.

[0012] Preferably, a square plate is fixed to the outer end of the guide plate, and when the two U-shaped frames are attached, the square plate will also engage with the square groove on one side of the protective shell.

[0013] The two square plates on the same side are fitted with handles together.

[0014] Preferably, a limiting slot is installed on both sides of the square groove on one side of the protective shell. A stop block can be placed in the limiting slot. When the two U-shaped frames are attached, the placed stop block is attached to the protective shell and the side wall of the square plate.

[0015] Preferably, anti-slip pads can be provided on the surfaces of the arc-shaped grooves corresponding to the bottom of the clamping block and the top of the positioning seat.

[0016] Compared with related technologies, the marine arresting cable toughness testing device provided by this utility model has the following advantages:

[0017] This utility model of marine arresting cable toughness testing equipment achieves efficient clamping of arresting cables through a unique positioning component and movable shell component design. During positioning, only two workers need to push the guide plate simultaneously to close the U-shaped frame. During the closing process, the guide plate applies pressure to the square rod through the pulley, causing the clamping block to slide down and firmly clamp both ends of the sample arresting cable. Unlike traditional testing methods, there is no need to use multiple bolts to fix the pressure block to prevent upward movement, which greatly simplifies the clamping and unclamping operation process, saves time and manpower, improves testing efficiency, and has good linkage.

[0018] Compared to the traditional testing schemes that lack a limiting structure and have insufficient protective performance after the movable door is closed, the movable shell assembly of this utility model has a reliable limiting and protective design. When the two U-shaped frames are attached, the square plate engages with the square groove on one side of the protective shell, and then the stop block is engaged and placed in the limiting slot, so that the two U-shaped frames are in a stable state, ensuring that the U-shaped frames will not move outward during toughness testing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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 without creative effort are within the protection scope of the present utility model.

[0028] Depend on Figures 1-7This invention provides a marine arresting cable toughness testing device, comprising a platform 1, with two protective shells 11 mounted on the top of the platform 1, and hydraulic rods 12 installed inside the protective shells 11. Positioning seats 13 are mounted on the output ends of the hydraulic rods 12, and the positioning seats 13 are slidably connected to the top of the platform 1. A positioning assembly 2 is mounted on the top of the positioning seats 13. A movable shell assembly 3 is mounted inside the protective shells 11. The positioning assembly 2 includes a U-shaped frame 25 fixed to the top of the positioning seats 13, and a clamping block 21 slidably mounted inside the U-shaped frame 25. The bottom of the clamping block 21 and the top of the positioning seats 13 have corresponding arc-shaped grooves. Two square rods 22 passing through the U-shaped frame 25 are fixed to the top of the clamping block 21, and pulleys 23 are mounted on the top of the square rods 22. The grooves on the top of the clamping block 21 and the U-shaped frame 25 are connected to the positioning seat 13. The frame 25 is connected to a return spring 24. The square rod 22 moves up and down through the closing operation of the movable shell assembly 3. Anti-slip pads can be set on the surfaces of the arc-shaped grooves corresponding to the bottom of the clamping block 21 and the top of the positioning seat 13. Marine arresting cables are usually composed of high-strength steel wires, which have extremely high tensile strength and relatively smooth surfaces. During toughness testing, a large tensile force needs to be applied to the arresting cable. If there are no anti-slip pads on the surface of the arc-shaped groove, the arresting cable is prone to slipping in the arc-shaped groove under the action of tensile force, resulting in unstable clamping and affecting the accuracy of the test results. Anti-slip pads can increase the friction between the arresting cable and the arc-shaped groove, so that the arresting cable can be more firmly fixed in the arc-shaped groove when subjected to tensile force, ensuring the stability of clamping and thus improving the reliability of the test results.

[0029] The movable shell assembly 3 includes a U-shaped frame 31 that is slidably installed on the inner wall of the protective shell 11. The U-shaped frame 31 has a three-section design and an integrated guide plate 32. The guide plate 32 extends out from one end of the protective shell 11. The guide plate 32 corresponds to the position of the pulley 23, and the end of the guide plate 32 facing the pulley 23 has an arc surface design.

[0030] Through the design of positioning component 2 and movable shell component 3, during positioning, both U-shaped frames 31 are in the open state and located inside the protective shell 11. At this time, the two ends of the sample restraint rope are bent into U-shapes and placed in the arc-shaped groove at the top of the positioning seat 13. Then, two workers simultaneously push the guide plate 32 to move the U-shaped frames 31 to close them. When the two U-shaped frames 31 are in contact, the other end of the U-shaped frame 31 is still partially inside the protective shell 11. During the closing process, the arc-shaped end of the guide plate 32 will contact the pulley 23. At this time, as the U-shaped frames 31 continue to close, the guide plate 32 applies downward pressure to the square rod 22 through the pulley 23, causing the square rod 22 to drive the clamping block. 21 slides downward along the U-shaped frame 25, the return spring 24 is compressed, and the arc-shaped groove at the bottom of the clamping block 21 gradually approaches the arc-shaped groove at the top of the positioning seat 13, finally firmly clamping both ends of the sample blocking rope between them, thus achieving rope positioning. After positioning is completed, the hydraulic rod 12 is activated, driving the positioning seat 13 to slide on the top of the equipment platform 1, applying tension to the sample blocking rope, thereby performing toughness testing. During the testing process, the pulley 23 slides at the bottom of the guide plate 32. If the rope breaks or other abnormalities occur, the protective shell 11 and the closed U-shaped frame 31 provide protection, effectively preventing the broken rope from flying and injuring people, thus ensuring the safety of the operators.

[0031] The U-shaped frame 31 has openings on both sides, and tempered glass 34 is installed in the openings.

[0032] Furthermore, the tempered glass 34 facilitates the observation of the internal situation by the staff. When the U-shaped frame 31 is closed, the tempered glass 34 is located on one side of the protective shell 11, and the U-shaped frame 31 can be designed with a sealing gasket.

[0033] A square plate 33 is fixed to the outer end of the guide plate 32. When the two U-shaped frames 31 are attached, the square plate 33 will also engage with the square groove on one side of the protective shell 11. The two square plates 33 on the same side are used to install the handle.

[0034] Furthermore, the square plate 33 can be positioned to ensure that the two U-shaped frames 31 can be moved to the center position for contact, which is very practical. The handle can be used to pull the U-shaped frames 31 when they are moving.

[0035] On one side of the protective shell 11, limit slots 14 are installed on both sides of the square groove. The limit slots 14 can hold the stop block 15. When the two U-shaped frames 31 are attached, the placed stop block 15 is attached to the side wall of the protective shell 11 and the square plate 33.

[0036] Furthermore, through the design of the limiting slot 14 and the stop block 15, after the two U-shaped frames 31 are attached, the stop block 15 can be locked in the limiting slot 14. In this way, the square plate 33 cannot move outward, and the two U-shaped frames 31 are in a stable state, ensuring that the U-shaped frames 31 will not move outward during toughness testing. This is very practical.

[0037] Working principle: During the toughness test of marine arresting cables, the two U-shaped frames 31 are initially in the open state and located inside the protective shell 11. The two ends of the sample arresting rope are bent into a U-shape and placed in the arc-shaped groove at the top of the positioning seat 13. Then, two workers simultaneously push the guide plate 32, causing the U-shaped frames 31 to move and close. During the closing process, the arc-shaped end of the guide plate 32 contacts the pulley 23, which applies downward pressure to the square rod 22. The square rod 22 drives the clamping block 21 to slide downward along the U-shaped frame 25, compressing the return spring 24. The arc-shaped groove at the bottom of the clamping block 21 gradually approaches the arc-shaped groove at the top of the positioning seat 13. Finally, the two ends of the sample barrier rope are firmly clamped to achieve positioning; at this time, the square plate 33 engages with the square groove on one side of the protective shell 11, and the stop block 15 is engaged and placed in the limiting slot 14, so that the two U-shaped frames 31 are in a stable state; then the two hydraulic rods 12 are activated, driving the positioning seat 13 to slide on the top of the equipment platform 1, applying tension to the sample barrier rope for toughness testing. During the test, the pulley 23 slides at the bottom of the guide plate 32, and the protective shell 11 and the closed U-shaped frame 31 play a protective role to prevent the broken rope from flying and injuring people; the staff can observe the internal situation through the tempered glass 34.
