Technical Field
[0001] The utility model relates to the technical field of aerospace tail fin transportation and docking installation, in particular to a rocket tail fin installation handle device. Background Art
[0002] In recent years, with the continuous development of the aerospace industry, the test operation work at the launch site has become more and more solidified, mainly including the installation of rocket tail fins, etc. Since rockets are high-value aerospace products, once an error occurs in the operation of the rocket, it will cause huge and even irreparable losses. Therefore, there are strict standards and requirements for the professional level and practical operation ability of the post personnel.
[0003] The tail fin is a supporting product of the first-stage rocket body structure. It is installed on the tail section of the first stage and constitutes the aerodynamic shape of the entire rocket body. It can improve the static stability of the rocket, meet the needs of rocket control stability, and withstand all loads in various mechanical environments during production, ground testing, and launch. In the aerospace test and launch process, the earliest rocket tail fin installation was carried, erected, and adjusted by operators by hand. During the previous tail fin installation processes, there have been safety problems caused by personnel slipping their hands. Later, the tail fin installation was improved by carrying and tying the tail fin. After many practical installations, it was found that more people were required during the installation of the tail fin, the assembly time was long, and the process and operation were complicated.
[0004] Specifically:
[0005] 1. When installing the tail fin, two groups of people are generally required, and each group requires multiple people. In addition to the personnel who lift the rocket tail fin, the installation of the tail fin requires relatively more people. Due to the narrow space at the rocket product installation site, it is inconvenient to install the tail fin with more people.
[0006] 2. When the tail fin is docked with the rocket, multiple people are required to work together outside the cabin to make adjustments. In addition, a designated person is required to stand and squat on the next step, carry the tail fin on his shoulders, and make fine adjustments to the height of the tail fin.
[0007] 3. The tying method of the tail wing is relatively complicated. Before installing the tail wing, the assembler ties the tail wing with a tie belt. The tying method is complicated, and it is inconvenient for the operator to operate during transportation, which may easily damage the tail wing. During the tying process of the transportation belt, skilled operators are required. If the operator has not received a certain amount of operation training, the tying may need to be repeated. The tying method of the tie belt is complicated, and if the tying is not in place, there may be a risk of the product falling off, causing bumps, and injuries to personnel;
[0008] 4. The height adjustment accuracy of the tail wing is poor and the operation is inconvenient, which affects the installation efficiency of the personnel. Traditional tail wing installation usually requires the cooperation of multiple people, and the operation method is complicated, inconvenient, and inefficient. There is a risk of product falling off, collision, and injury to personnel, and poor height accuracy. Utility Model Content

The connecting stud 4 is a section of external thread. The hexagon 5 is a hexagonal table of a certain height with a regular hexagonal cross section, and the parallel side width of the regular hexagon can match the national standard wrench. The gripping handle 8 is a truncated table of a certain height with a circular cross section, and the height is slightly larger than the width of an adult's palm. The front column 6 and the rear column 9 are truncated tables with circular cross sections, and their outer diameters are slightly larger than the outer diameter of the gripping handle, wherein the height of the rear column 9 is slightly larger than the depth of the bottom hole of its internal threaded hole; fillets 7 are provided at the transitions on both sides of the front column 6, the rear column 9 and the gripping handle 8 to prevent the operator from slipping and hurting his hands when holding the sliding handle to carry and install the tail wing; there is an internal threaded hole 10 at the end of the rear column 9.
[0035] The hexagon is on the left side of the connecting stud. The width of the parallel side of the hexagon is 32mm and the height is 10mm. Use an open-end wrench to clamp the hexagon and tighten the thread.
[0036] Tighten the screw handle when installing it on the tail wing; the grip handle is 120mm long and is used to hold the screw handle when carrying the tail wing, making it easier to carry and install the tail wing;
[0037] The front and rear columns are 20mm and 30mm long respectively, with a radius of 7.5mm to prevent the tail from slipping when people hold it; the 35mm diameter cylinder is 30mm long and has a 27mm deep M16×2mm threaded hole. The rear column can be connected to the lifting ring through threads, which is convenient for use when lifting the tail.
[0038] like Figure 1 and Figure 2 As shown, the eye screw 1 is composed of a ring 11 and a screw 12. Except for the shorter length of the stud, the rest is the same as the national standard eye screw GB 825-88M16.
[0039] like Figure 1 and Figure 3As shown, the rubber bushing 3 is pressed from industrial rubber and is a hollow cylinder, whose inner diameter matches the grip handle, whose outer diameter is equivalent to the inner diameter of the ring formed by an adult's palm, and whose height is slightly greater than the width of an adult's palm.
[0040] The grip handle is covered with a 2mm thick rubber bushing, and the surface of the bushing is processed into a knurled shape to achieve shock absorption and anti-slip properties, preventing hands from getting cold when directly gripping the metal grip handle in winter, thereby protecting the hands.
[0041] like Figure 1 and Figure 3 As shown, the connecting stud 4 is a structure connected to the tail threaded hole, and its thread size matches the tail threaded hole size. The stud thread length is slightly smaller than the tail threaded hole depth, and there is a small section of cylinder with a diameter equal to the outer diameter of the thread near the hexagonal end 5.
[0042] like Figure 1 and Figure 3 As shown, the stud of the eye screw 1 is connected to the internal threaded hole 10 at the end of the rear column 9 at the left end of the screw handle 2, the size of the stud of the eye screw 1 matches the thread size of the internal threaded hole 10 at the end of the rear column 9 at the left end, and the thread length of the eye screw 1 is slightly smaller than the depth of the internal threaded hole at the left end of the screw handle 2.
[0043] It can be connected with a four-hook sling for mechanical lifting and turning.
[0044] like Figure 1-Figure 6 As shown, the working principle of the utility model is as follows: taking a certain type of rocket tail as an example, three M10×1.5 threaded holes are punched on the outer surface of the tail, the upper and lower holes on the left side of the tail are 950mm apart, and the distance between the left and right holes of the tail is 840mm. Except for the thread length being 5mm shorter, the other parts of the lifting ring adopt the national standard lifting ring screw GB 825-88M16; the bushing is pressed from industrial rubber and has knurling on the outside, which can also be replaced by wrapping with a handlebar. The specific process of horizontal transportation, lifting, flipping, and adjusting the docking of the tail is as follows:
[0045] 1. Installation of tooling and horizontal transportation of the tail. Before transportation, tighten the six lifting ring handle tooling at A, D, B, E, C, and F on the threaded holes on both sides of the tail, and tighten them with an S=32mm open-end wrench. Two people in front and behind hold the four handle toolings A, C, D, and F to lift the tail out of the tail box and carry it horizontally to the installation site of the tail.
[0046] 2. Lifting the tail wing: Install the lifting ring handle tooling on the tail wing A, C, D, and F, connect the four-hook lifting device, and use a crane to lift it to the installation position of the tail wing on the movable platform.
[0047] 3. Tail flip. When flipping manually, lift up the tail A and D points, hold points B and E to lower the rear end of the tail and flip it to the installation docking position so that it is ready for docking installation. When flipping mechanically, hold points B and E by hand and disconnect the four-hook sling from points C and F.
[0048] 4. Tail installation. The interface between the tail and the rocket tail section is located on the longest end rib of the tail, which is four protruding ears. The four ears are of the same size, in groups of two, and the two ears in each group are coaxial. There are two supports at the corresponding position on the rocket tail section, with two notches in the middle of the supports. The height of the notches is slightly greater than the height of the ears, which are used to match the ears. When the tail is installed on the tail section, the two groups of ears on the tail need to be embedded in the slots of the tail section support. The relative position of the tail and the tail end is adjusted up and down, left and right, and front and back through the lifting ring handle tooling at A, D, B, E, C, and F. The tail and the product are docked and installed by adjusting the distance up and down to the required height for docking at points A and B. Point C assists the tail to be adjusted up and down and left and right to the appropriate position, so that the tail can be installed and docked better and faster. Make the tail ear coaxial with the mounting hole on the tail end support, then insert the bolt into the mounting hole, screw on the nut and tighten it with a fixed torque to fix the tail.
[0049] 5. Removal of the tooling: After the tail is installed, loosen the six tail lifting ring handle tooling on the tail with an open-end wrench, unscrew the tail lifting ring handle tooling by hand, and remove the tooling.
[0050] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model.
