Description

Technical Field

[0001] This utility model relates to the field of aviation technology, specifically to an auxiliary tool for installing aircraft steel cable tensioning sleeves. Background Technology

[0002] During the installation and alignment of aircraft cables, the maintenance manual clearly stipulates that the number of exposed teeth at both ends of the cable tensioning sleeve must be consistent, and the cable tension must be uniform and meet the design tension requirements. This requirement means that assembly personnel may mistakenly adjust one side of the cable end during assembly, leading to incorrect rotation and loosening of the cable strands. Any deviation can affect the cable's tension performance and service life, ultimately impacting the overall safety of the aircraft.

[0003] The assembly of existing cable tensioning sleeves typically requires two maintenance personnel working together: one to hold the cable end in place, and the other to manually adjust the tensioning sleeve. This method is not only inefficient, but the manual alignment during adjustment is prone to errors in the number of exposed teeth. Furthermore, it is not suitable for two-person assembly in confined spaces. Simultaneously, the adjustment requires a high degree of communication and coordination; insufficient coordination can lead to asynchronous rotation of the cable ends, potentially increasing the probability of human error, the difficulty of adjustment, and the time required. Prolonged manual operation also increases the workload of maintenance personnel, hindering efficient maintenance work.

[0004] Therefore, it is necessary to develop an auxiliary tool to improve the installation efficiency and adjustment accuracy of steel cables. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this utility model is to provide an auxiliary tool for installing aircraft cable tensioning sleeves. This auxiliary tool has a simple structure, is easy to operate, and can improve the efficiency and accuracy of cable installation and adjustment.

[0006] To achieve the above objectives, this utility model proposes an auxiliary tool for installing aircraft steel cable tensioning sleeves, which includes:

[0007] Base;

[0008] Two slide blocks are mounted on the base. The two slide blocks can slide freely in the same straight line direction. Each of the two slide blocks is provided with a positioning groove for positioning the end of the steel cable. Both ends of the two positioning grooves are open so that the ends of the two steel cables can be placed into the two positioning grooves one by one. The two slide blocks define an installation space for installing the tightening and loosening sleeving.

[0009] Fasteners installed on the slide blocks are used to fix the cable ends in the positioning grooves so that the two cable ends on the two slide blocks are on the same straight line.

[0010] An adjusting screw is mounted on the base, the adjusting screw being used to adjust the distance between the two slides.

[0011] According to this utility model, an auxiliary tool for installing aircraft cable tensioning sleeves is proposed. Two adjustable sliding blocks are used to initially position the ends of two pre-connected steel cables. Fasteners are used to fix the cable ends to the sliding blocks, ensuring the two cable ends are aligned. An adjusting screw is then used to adjust the distance between the two sliding blocks, facilitating the installation and adjustment of the tensioning sleeve between the two sliding blocks. This ensures that the number of exposed teeth is consistent after the tensioning sleeve is connected to the two cable ends. This auxiliary tool for installing aircraft cable tensioning sleeves has a simple structure, is easy to operate, and can improve the efficiency and accuracy of cable installation and adjustment.

[0012] In addition, the aircraft steel cable tensioning sleeve installation auxiliary tool proposed in the above embodiments of this utility model may also have the following additional technical features:

[0013] Optionally, the base has a notch located between the two slides.

[0014] Optionally, both slides are provided with a first connecting hole, which communicates with the side of the positioning groove.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] The following is for reference. Figure 1 The present invention describes in detail the implementation of the auxiliary tool for installing the tensioning sleeve of aircraft steel cables according to the embodiments of the present invention.

[0026] The aircraft cable tensioning sleeve installation auxiliary tool according to an embodiment of the present utility model includes:

[0027] Base 1;

[0028] Two slide blocks 2 are installed on the base 1. The two slide blocks 2 can slide freely in the same straight line direction. Both slide blocks 2 are provided with positioning grooves 21 for positioning the steel cable ends 4. Both ends of the two positioning grooves 21 are open so that the two steel cable ends 4 can be placed into the two positioning grooves 21 one by one. The two slide blocks 2 define the installation space for installing the tightening and loosening screw sleeve 5.

[0029] Fasteners 3 are installed on slide 2 to fix the steel cable end 4 in the positioning groove 21 so that the two steel cable ends 4 on the two slides 2 can be placed into the two positioning grooves 21 one by one.

[0030] An adjusting screw (not shown) is mounted on the base 1. The adjusting screw is used to adjust the distance between the two slides 2.

[0031] In other words, the tension of the steel cable is adjusted by the tensioning sleeve 5 between the two steel cables. The ends of the two steel cables are provided with cable ends 4. The two cable ends 4 are connected to the two ends of the tensioning sleeve 5 by positive and negative threads. When adjusting or installing the tensioning sleeve 5, the auxiliary tool is placed along the length of the steel cable. Then, the two cable ends 4 are placed into the positioning grooves 21 on the two slide blocks 2 one by one, and then fixed by the fasteners 3. After being fixed, the two cable ends 4 are in a coaxial state. The relative distance between the two slide blocks 2 is adjusted by adjusting the screw to drive the two slide blocks 2 to slide, thereby adjusting the distance between the two cable ends 4. At this time, the operation of installing or disassembling and replacing the tensioning sleeve 5 and adjusting the tensioning sleeve 5 can be performed between the two slide blocks 2, thus ensuring the positional accuracy between the two steel cables and the tensioning sleeve 5. The positioning groove 21 can be configured with a concave-convex shape that matches the outer contour of the cable end 4, which facilitates precise positioning of the cable end 4. The two slides 2 can be adjusted synchronously by a screw with positive and negative threads engaging with the threaded hole on the slide 2, or one slide 2 can be adjusted individually by engaging with a screw with a one-way thread. The base 1 can be set with a scale for reference when adjusting the slide 2. The slide 2 and the base 1 can be connected by a sliding pair, or the slide 2 and the base 1 can be connected by a concave-convex engagement.

[0032] Therefore, the ends 4 of the two pre-connected steel cables are positioned by two sliding and adjustable slide blocks 2, and the ends 4 are fixed on the slide blocks 2 by fasteners 3, so that the two ends 4 are on the same straight line. Then, the distance between the two slide blocks 2 is adjusted by adjusting the screw, so that the distance between the two ends 4 is adjusted, which facilitates the installation and adjustment of the tensioning sleeve 5 between the two slide blocks 2, thereby ensuring that the number of exposed teeth of the tensioning sleeve 5 is consistent after it is connected to the two ends 4. This aircraft steel cable tensioning sleeve installation auxiliary tool has a simple structure, is easy to operate, and can improve the efficiency and adjustment accuracy of steel cable installation and adjustment.

[0033] Optionally, the base 1 is provided with a notch 11, which is located between the two slides 2. Understandably, by providing the notch 11, a larger clearance space can be formed between the two slides 2, thereby facilitating the insertion of a lever tool into the adjustment hole 51 of the tensioning sleeve 5 for rotational adjustment.

[0034] Optionally, both slides 2 are provided with first connecting holes 22, which communicate with the side of the positioning groove 21. Fasteners 3 are threaded into the first connecting holes 22 to abut against the connector safety clamp groove 41 of the cable end 4, thus fixing the cable end 4 within the positioning groove 21. Understandably, the threaded connection between the fastener 3 and the first connecting holes 22 allows the fastener 3 to abut against the connector safety clamp groove 41 of the cable end 4, thereby securely fixing the cable end 4. There can be two first connecting holes 22, with each hole corresponding to the other on opposite sides of the positioning groove 21. The fastener 3 can be a screw.

[0035] Optionally, both slides 2 are provided with second connecting holes 23. The adjusting screw is rotatably connected to the second connecting hole 23 and threadedly connected to the base 1, or the adjusting screw is threadedly connected to the second connecting hole 23 and rotatably connected to the base 1. Understandably, the rotatable connection between the second connecting hole 23 and the adjusting screw, and the threaded connection between the adjusting screw and the base 1, allows the adjusting screw to extend and retract when rotating, thus moving the slide 2 and adjusting the distance between the two slides 2, thereby adjusting the distance between the two steel cable ends 4. The threaded connection between the adjusting screw and the second connecting hole 23, and the rotatable connection between the adjusting screw and the base 1, allows the adjusting screw to remain stationary while rotating, driving the slide 2 to move through the threaded engagement, thereby adjusting the distance between the two slides 2. Two second connecting holes 23 can be provided on each slide 2, and the two second connecting holes 23 are correspondingly located on the lower side of the positioning groove 21.

[0036] Optionally, the base 1 is provided with a slide rail 12, and the slide block 2 is provided with a groove 24 adapted to the slide rail 12. Understandably, the slide rail 12 of the base 1 and the groove 24 of the slide block 2 cooperate to allow relative sliding between the slide block 2 and the base 1, thereby facilitating adjustment of the relative position between the two steel cable ends 4. The slide rail 12 is divided into left and right sections by a notch 11, and two slide blocks 2 are correspondingly arranged on the left and right sections of the slide rail 12.

[0037] Furthermore, the cross-sections of the slide rail 12 and the slide groove 24 are triangular. Understandably, by setting the cross-sections of the slide rail 12 and the slide groove 24 to be triangular, the stability of sliding between the slide block 2 and the base 1 can be improved, thereby ensuring the coaxiality and adjustment accuracy of the two steel cable ends 4.

[0038] Optionally, the base 1 is provided with a limiting member 13, which is used to limit the sliding range of the slide block 2. Understandably, by setting the limiting member 13, the slide block 2 can be prevented from detaching from the base 1 during sliding, while limiting the sliding range of the slide block 2, facilitating quick positioning between the cable end 4 and the slide block 2. The limiting member 13 can be detachably installed on the slide rail 12 with screws, facilitating the installation of the slide block 2 and the base 1.
