However, in actual use, if the steel cable is accidentally loosened during disassembly by direct contact, the original tension balance will be broken. The tension change will be transmitted to the adjacent steel cables, causing the adjacent steel cables to fall off, which cannot effectively ensure the operational safety during the repair process.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0019] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model is provided: an aircraft steel cable tension holding clamp tool, including a lower clamp plate 1, an upper clamp plate 2 is provided on the top of the lower clamp plate 1, a clamping mechanism 3 is provided between adjacent lower clamp plate 1 and upper clamp plate 2, the clamping mechanism 3 is used to clamp the steel cable, and an installation mechanism 4 is provided on the outer side of the upper clamp plate 2, the installation mechanism 4 is used for opening, closing and fixing the device. The clamping mechanism 3 includes a lower clamping seat 31, the bottom of which is fixedly connected to the inner bottom of the lower clamping plate 1. An upper clamping seat 32 is fixedly connected to the inner top of the upper clamping plate 2. Both the lower clamping seat 31 and the upper clamping seat 32 are made of 6061-T6 aluminum alloy. The surfaces of both the lower clamping seat 31 and the upper clamping seat 32 are treated with hard anodizing. Adhesive layers 33 are fixedly connected between adjacent lower clamping seats 31 and upper clamping seats 32. Multiple V-grooves 34 are provided between adjacent two adhesive layers 33. Both adhesive layers 33 are made of polyetheretherketone (PEEK). The size of the multiple V-grooves 34 decreases from left to right. The clamping mechanism 3 also includes multiple rubber strips 35. The outer sides of the multiple rubber strips 35 are fixedly connected to the inner front and rear ends of the lower clamping plate 1 and the inner front and rear ends of the upper clamping plate 2, respectively. The multiple rubber strips 35 are made of VMQ silicone rubber. The outer edges of the multiple rubber strips 35 are chamfered. Specifically, the lower clamping plate 1 and the upper clamping plate 2 work together to form the main frame of the tool, the clamping mechanism 3 achieves stable clamping of the steel cable, and the installation mechanism 4 controls the opening, closing and fixing of the tool, working together to ensure the clamping operation needs during the aircraft steel cable maintenance process. When the clamping mechanism 3 is working, before clamping the aircraft steel cable, the upper clamping plate 2 and the lower clamping plate 1 are opened by the installation mechanism 4. The steel cable to be clamped is placed on the top of the lower clamping seat 31 at the bottom of the inner side of the lower clamping plate 1. The bonding layer 33 on the top of the lower clamping seat 31 contacts the bottom of the steel cable. Through the cooperation between the bonding layer 33 and the lower clamping seat 31, the steel cable is initially supported. According to the actual size of the steel cable, the corresponding size of the V-groove 34 on the bonding layer 33 between the lower clamping seat 31 and the upper clamping seat 32 is selected. The steel cable is inserted into the V-groove 34. Through the cooperation between the V-groove 34 and the bonding layer 33, the steel cable is initially positioned in the horizontal direction to avoid the steel cable from shifting left and right during the subsequent clamping process. Subsequently, the upper clamping plate 2 and the lower clamping plate 1 are closed by the installation mechanism 4. The upper clamping seat 32 on the top inner side of the upper clamping plate 2 moves down synchronously with the upper clamping plate 2. The bonding layer 33 at the bottom of the upper clamping seat 32 gradually approaches the top of the steel cable until the bonding layer 33 at the bottom of the upper clamping seat 32 is in complete contact with the top of the steel cable. Through the cooperation between the upper clamping seat 32 and the upper clamping plate 2, downward pressure is provided to the bonding layer 33, so that the bonding layer 33 tightly wraps the surface of the steel cable. Through the cooperation of the lower clamping seat 31, the upper clamping seat 32 and the bonding layer 33, the steel cable is secured. The cable is clamped and fixed in the vertical direction. Both the lower clamp 31 and the upper clamp 32 are made of a specific aluminum alloy and the surface is treated with hard anodizing. Through the material characteristics of the lower clamp 31 and the upper clamp 32, it is ensured that the clamp itself will not deform during the clamping process, thus ensuring the stability of the clamping structure. The bonding layer 33 is made of a specific material. Through the cooperation between the bonding layer 33 and the steel cable, the clamp is prevented from directly contacting the steel cable, which would cause wear on the surface of the steel cable. The friction between the bonding layer 33 and the steel cable is enhanced, thereby improving the clamping stability. During the clamping process, the rubber strips 35 on the inner front and rear ends of the lower clamping plate 1 and the inner front and rear ends of the upper clamping plate 2 simultaneously contact the connection points of the front and rear sides of the steel cable. The rubber strips 35 are made of a specific silicone rubber material and the outer edges are chamfered. Through the cooperation of the rubber strips 35 with the lower clamping plate 1 and the upper clamping plate 2, the steel cable is clamped from the front and rear direction, which restricts the movement of the steel cable in the front and rear direction. The material of the rubber strips 35 increases the friction between the steel cable and the steel cable. Through the cooperation of the rubber strips 35 with the bonding layer 33, the steel cable is stably clamped. When it is necessary to change to a different size of steel cable for clamping, the upper clamping plate 2 and the lower clamping plate 1 are opened through the installation mechanism 4, the steel cable is taken out from the current V-groove 34, and then the corresponding size of the V-groove 34 is selected according to the new steel cable size and re-inserted. Through the design of the V-groove 34 size decreasing from left to right, combined with the cooperation of the bonding layer 33 and the rubber strip 35, it can adapt to different sizes of aircraft steel cables.

[0020] Reference Figure 2 , Figure 3 and Figure 4The installation mechanism 4 includes two hinges 41, the left sides of which are fixedly connected to the right side of the lower clamping plate 1. The top right side of the lower clamping plate 1 and the top right side of the upper clamping plate 2 are provided with tie holes 42. The four corners of the top of the upper clamping plate 2 are threaded with screws 43. The top and bottom of the outer walls of the screws 43 are threaded with wing nuts 44. The installation mechanism 4 also includes multiple washers 45. The outer sides of the multiple washers 45 are respectively set between the adjacent wing nuts 44. The multiple washers 45 are all made of 17-4PH stainless steel. The installation mechanism 4 also includes multiple bolts 46. The left sides of the multiple bolts 46 are threadedly connected to the right side of the two hinges 41. The inner sides of the multiple bolts 46 are provided with internal hexagonal groove structures. The top of the upper clamping plate 2 is provided with a tensioning assembly 47. The tensioning assembly 47 includes multiple winches 471. The bottom of the multiple winches 471 is rotatably connected to the top of the upper clamping plate 2. The top of the multiple winches 471 is fixedly connected with an operating rod 472. Specifically, when the installation mechanism 4 controls the opening and closing of the tool, the left side of the two hinges 41 is fixed to the right side of the lower clamping plate 1, and the left side of the bolt 46 is threadedly connected to the right side of the hinge 41. Through the cooperation of the bolt 46 and the hinge 41, the hinge 41 is fixed to the right side of the upper clamping plate 2, so that the upper clamping plate 2 can rotate around the hinge 41. When the operator rotates the upper clamping plate 2 upward, the upper clamping plate 2 flips upward with the hinge 41 as the axis. Through the cooperation of the hinge 41 with the lower clamping plate 1 and the upper clamping plate 2, the tool is opened, making it easy to put the steel cable into the clamping mechanism 3. After the steel cable is placed, the upper clamping plate 2 is rotated downward until the upper clamping plate 2 and the lower clamping plate 1 return to the closed state. Through the rotation characteristics of the hinge 41, the tool can be opened and closed conveniently. After the tool is closed, it needs to be fixed. The screws 43 at the four corners of the top of the upper clamping plate 2 pass through the upper clamping plate 2 and the lower clamping plate 1. The wing nuts 44 at the top and bottom of the outer wall of the screws 43 are located at the top of the upper clamping plate 2 and the bottom of the lower clamping plate 1, respectively. Rotating the wing nuts 44 causes them to move towards the clamping plate through the cooperation between the wing nuts 44 and the screws 43. The washers 45 between the adjacent wing nuts 44 move with the wing nuts 44 until the washers 45 contact the surface of the clamping plate. Through the cooperation between the washers 45 and the wing nuts 44, the contact area between the wing nuts 44 and the clamping plate is increased, preventing the wing nuts 44 from damaging the surface of the clamping plate and enhancing the fixing stability. Continue to rotate the wing nuts 44 until they tightly fix the upper clamping plate 2 and the lower clamping plate 1. Through the cooperation of the screws 43, the wing nuts 44 and the washers 45, the tool is fixed after closing, preventing the tool from accidentally opening or closing during the clamping process. The tensioning assembly 47 is used to fix the steel cable, which passes through the winch 471. The operator rotates the operating lever 472 at the top of the winch 471, which drives the winch 471 to rotate on the top of the upper clamping plate 2. During the rotation of the winch 471, the steel cable is tightened. Through the cooperation between the winch 471 and the operating lever 472, the steel cable is additionally fixed. Through the cooperation between the winch 471 and the mooring hole 42, the clamping force of the clamping mechanism 3 on the steel cable is enhanced, preventing the steel cable from loosening during maintenance. When it is necessary to open the tool to remove the steel cable, the operating lever 472 is rotated in the opposite direction, the winch 471 loosens the rope, and then the wing nut 44 is rotated in the opposite direction to release the screw 43 from fixing the clamping plate. The upper clamping plate 2 is then rotated upward to realize the operation of tool opening, closing, fixing and tightening.

[0021] Working principle: The tool is opened by the installation mechanism 4. The left side of the bolt 46 is threaded to the right side of the hinge 41. The hinge 41 is fixed to the right side of the upper clamping plate 2 by the cooperation of the bolt 46 and the hinge 41. The operator rotates the upper clamping plate 2 upwards. The upper clamping plate 2 rotates around the hinge 41 as the axis. The tool is opened by the cooperation of the hinge 41 with the lower clamping plate 1 and the upper clamping plate 2. The steel cable to be clamped is placed on the top of the lower clamping seat 31 at the bottom of the inner side of the lower clamping plate 1. The bonding layer 33 on the top of the lower clamping seat 31 contacts the bottom of the steel cable. The corresponding V-groove 34 on the bonding layer 33 is selected according to the size of the steel cable. The steel cable is inserted into the V-groove 34. The steel cable is horizontally positioned by the cooperation of the V-groove 34 and the bonding layer 33. By using the closure tool of the installation mechanism 4, the upper clamping plate 2 is rotated downwards until it closes with the lower clamping plate 1. The upper clamping seat 32 on the top inner side of the upper clamping plate 2 moves downwards accordingly. The bonding layer 33 at the bottom of the upper clamping seat 32 contacts the top of the steel cable. The cooperation between the upper clamping seat 32 and the upper clamping plate 2 provides downward pressure to the bonding layer 33, causing the bonding layer 33 to wrap around the steel cable. The cooperation between the lower clamping seat 31, the upper clamping seat 32, and the bonding layer 33 achieves the upper and lower clamping and fixing of the steel cable. At the same time, the rubber strips 35 on the front and rear ends of the inner side of the lower clamping plate 1 and the upper clamping plate 2 contact the front and rear sides of the steel cable. The cooperation between the rubber strips 35 and the clamping plate assists in clamping the steel cable. The screw 43 at the top of the upper clamping plate 2 passes through the clamping plate through the fixing tool of the installation mechanism 4. The wing nut 44 on the outer wall of the screw 43 is rotated. The wing nut 44 drives the adjacent washer 45 to move to contact the clamping plate. The contact area is increased by the cooperation between the washer 45 and the wing nut 44. The clamping plate is tightly fixed by continuing to rotate the wing nut 44. Then the tensioning assembly 47 is started and the operating rod 472 at the top of the winch 471 is rotated. The operating rod 472 drives the winch 471 to rotate and tighten the steel cable. The clamping force is enhanced by the cooperation between the winch 471 and the mooring hole 42. After the cable repair is completed, rotate the operating lever 472 in the opposite direction to loosen the cable with the winch 471, rotate the wing nut 44 in the opposite direction to release the screw 43 from the lock, rotate the upper clamp 2 upward to open the tool, and remove the cable from the V-groove 34 to complete the cable clamping and repair operation, thus meeting the clamping requirements during the aircraft cable repair process.
