Description

Technical Field

[0001] The invention belongs to the technical field of aircraft launcher testing, and in particular relates to a launcher hoisting device. Background Art

[0002] During the development, production and repair process, the launcher needs to be installed on a fixed fixture to conduct performance testing under specific environmental conditions.

[0003] The launcher is mainly composed of three parts: the front fairing, the middle section, and the rear fairing. The front fairing is a truncated cone frame thin shell structure; the middle section is a cylindrical structure, which is the main load-bearing part, and two ears II are installed on the top of the middle section; the rear fairing is a cylindrical porous thin shell structure. The fixing fixture is an eight-sided cage structure; the upper end face is a frame structure with reinforcing ribs, and two buckles are installed below the upper end face for connecting with the two ears II of the launcher; the lower end face is fastened to the test bench; the front and rear end faces are closed hexagonal hollow structures, and the launcher can freely pass through the hollow parts of the front and rear end faces; the remaining four faces are frame structures with reinforcing ribs.

[0004] In order to truly simulate the working environment of the launcher on the aircraft, the launcher is connected to the fixture by a top hanging installation method. In order to rigidly transfer the vibration characteristics of the test bench to the launcher through the fixture, the fixture adopts a closed eight-sided cage structure, and in order to reduce the distortion during the transmission of vibration characteristics, the various surfaces of the fixture are required to be as close to the launcher as possible. The special connection requirements of the launcher and the special structural requirements of the fixture lead to special loading and unloading requirements for the launcher: before the launcher is sent into the fixture, the center of gravity must be found and the launcher must be axially aligned with the fixture; the launcher must be kept in a horizontal state during the process of being sent into the fixture; after being sent into the fixture, the launcher's ear II must be coordinated with the buckle of the fixture to avoid tedious adjustments in a small space.

[0005] Since the launcher is a large piece with a large weight, it cannot be loaded and unloaded by manpower alone and requires external force. Since there are other equipment required for the test on the ground around the test bench, it is not possible to use a lifting mechanism on the ground, so it can only be hoisted.

[0006] The existing lifting method uses two lifting ropes to adjust the center of gravity by adjusting the length of the lifting ropes and the position of the tying to make the launcher level. Since the front and rear fairings of the launcher are thin-walled structures and cannot withstand gravity, the tying position of the lifting rope can only be adjusted in the middle section. Pass the launcher axially through the front and rear end faces of the fixing fixture. Since the front and rear end faces of the fixing fixture are closed hexagonal hollow structures, the front end sling is restricted from entering the fixture. Therefore, it is necessary to support one end of the launcher, remove a lifting rope, pass the lifting rope through the hole on the upper end face of the fixing fixture, re-hang the launcher, and then send it into the fixing fixture. Then, in a narrow space, adjust the position of the launcher so that the lifting ear II of the launcher is coordinated with the buckle of the fixing fixture.

[0007] The existing lifting method requires repeated adjustment of the sling length and the tie position when adjusting the center of gravity to ensure that the launcher maintains a horizontal posture. The process of sending the launcher into the fixed fixture requires careful cooperation of multiple people. From removing a lifting rope to lifting it again, the launcher needs to be supported manually. If you are not careful, the launcher will collide with the fixed fixture, damaging the launcher shell and causing the launcher to be reworked and repaired. The space left after the launcher is sent into the fixed fixture is small, which is not conducive to the operation of adjusting the hanging point position. The existing lifting method is prone to economic losses, prolonging the delivery cycle of the launcher, and affecting the user's normal training tasks. At the same time, during the lifting process, the personnel are close to the launcher, which is easy to cause personal injury. Taking into account the three dimensions of work efficiency, quality risk and personal safety, the existing lifting method has extremely poor operability; it is urgent to design a new launcher lifting method and device. Summary of the invention

[0008] The purpose of the present invention is to provide a launcher hoisting method and device thereof, which are used to solve the problems of low working efficiency, high quality risk and endangerment to personal safety of the existing hoisting methods.

[0016] Furthermore, the rotating component also includes a protective cover, which is a tubular structure, made of soft material, and is sleeved on the support beam to protect the launcher during hoisting.

[0017] Furthermore, the connection and stop components of the launcher lifting device include a fixing plate I, a fixing plate II, a stop pin, a bolt and a nut; the fixing plate I and the fixing plate II are exactly the same, and are fan-shaped structures, with a total of 3 groups of through holes, which are defined as E holes, F holes, and G holes respectively; the bolts pass through the E holes of the fixing plate I, the A holes of the hanging beam II, and the E holes of the fixing plate II, and are fastened with nuts, and the hanging beam II fits tightly with the fixing plate I and the fixing plate II without any gap; the bolts pass through the F holes of the fixing plate I, the B holes of the rotating beam, and the F holes of the fixing plate II, and are fixed with nuts , a certain gap is left between the rotating beam and the fixed plates I and II, so that the rotating beam can rotate around the bolt; the stop pin passes through the G1 hole of the fixed plate I, the C hole of the rotating beam, the G1 hole of the fixed plate II, or passes through the G2 hole of the fixed plate I, the D hole of the rotating beam, the G2 hole of the fixed plate II, or passes through the G3 hole of the fixed plate I, the D hole of the rotating beam, the G3 hole of the fixed plate II, so that the rotating beam is stopped in the rotating direction; different perforation stopping methods can realize different angles of the rotating parts, thereby realizing the hoisting of launchers with different diameters.

[0018] Furthermore, the fixing plate Ⅰ and the fixing plate Ⅱ are exactly the same. The sizes and positions of the three groups of through holes, namely the E holes, the F holes, and the G holes, are as follows: The 4 through holes in group E are evenly distributed along the axial direction of the symmetry axis of the fixing plate, and the size of the holes and the hole pitch are the same as those of the group A through holes of the hanging beam Ⅱ; The 2 through holes in group F are symmetrically distributed on both sides of the symmetry axis of the fixing plate, and the hole diameter is the same as that of the B hole of the rotary beam; The 2 through holes of the G1 holes are symmetrically distributed on both sides of the symmetry axis of the fixing plate, and the distance between the F hole and the G1 hole on the same side of the symmetry axis of the fixing plate is the same as the distance between the B hole and the C hole on the rotary beam; The 2 through holes of the G2 holes are symmetrically distributed on both sides of the symmetry axis of the fixing plate, and the distance between the F hole and the G2 hole on the same side of the symmetry axis of the fixing plate is the same as the distance between the B hole and the D hole on the rotary beam; The 2 through holes of the G3 holes are symmetrically distributed on both sides of the symmetry axis of the fixing plate, and the distance between the F hole and the G3 hole on the same side of the symmetry axis of the fixing plate is the same as the distance between the B hole and the D hole on the rotary beam; The through holes of the G group on the fixing plate are the same as the hole diameters of the C hole and the D hole on the rotary beam.

[0020] The beneficial effects of the present invention: The hoisting device composed of the hanging beam component, two rotary components, and the connecting stop component in the present invention realizes the efficient and safe completion of the hoisting process of the transmitter from the ground to the fixed fixture. It solves the problems of the original hoisting method that requires careful cooperation of multiple people, has low work efficiency, is easy to damage the product, and has potential personal safety risks. In this solution, by adjusting the position of the lifting lug Ⅰ on the hanging beam Ⅰ, the center of gravity position is found, so that the transmitter maintains a horizontal state, and the axial alignment is completed before the transmitter is sent into the fixed fixture to adapt to the spatial position of the buckle in the fixed fixture. Through the overall "U-shaped" structure of the hoisting device, the transmitter can be sent into the fixed fixture without space limitation and in a horizontal posture, without secondary hoisting, avoiding repeated adjustment in a narrow space to ensure the coordination between the lifting lug Ⅱ of the transmitter and the buckle of the fixed fixture. In addition, through the combination of different hole positions on the fixing plate Ⅰ, the rotary beam, and the fixing plate Ⅱ, the two rotary components can be opened at different angles, thereby realizing the hoisting of transmitters with different diameters. The stop pin completes the rapid stop of the rotary component, and through the rotation of the stop block, the falling off of the stop pin is prevented to ensure reliable stopping.

Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] See also Figures 3 to 10In the specific implementation process of the present invention, a launcher hoisting method and device are designed, including a hanging beam component 12, two rotating components 10 and a connecting stop component 11; Figure 5 The suspension beam component 12 includes a suspension beam Ⅰ15, a suspension beam Ⅱ13, a reinforcement rib Ⅰ14 and a lifting lug Ⅰ16; Figure 6 As described above, the rotating component 10 includes a rotating beam 17, a supporting beam 19, a reinforcing rib II 18 and a protective cover 20; Figure 7 As mentioned above, the connection stopper 11 includes a fixing plate I 22, a fixing plate II 24, a stopper pin 21, a bolt 23 and a nut 25. Fig. 9 Said stop pin 21 comprises a pin body 26, a stop block 27 and a cylindrical pin 28;

[0034] The assembly is as follows: the hanging beam Ⅱ13 is a solid square steel, with a row of through holes in group A on the left and right end faces, and the upper end face is cut off at 45°. The hanging beam Ⅰ15 and the hanging beam Ⅱ13 are welded and fixed along the 45° section to form an L shape. The reinforcing rib Ⅰ14 is a triangular steel plate, and the right-angled sides are welded and fixed to the hanging beam Ⅰ15 and the hanging beam Ⅱ13 respectively. The lifting lug Ⅰ16 is connected to the hanging beam Ⅰ15 through a thread, and the threaded hole on the hanging beam Ⅰ15 is selected according to the center of gravity during lifting, so that the launcher 2 can maintain a horizontal position during lifting;

[0035] The rotating component 10 of the launcher hoisting device includes a rotating beam 17, a support beam 19, a reinforcing rib II 18 and a protective cover 20. The rotating beam 17 is a solid square steel, the upper and lower end faces are arc structures, and the left and right end faces have three through holes B, C, and D. The support beam 19 is a cylindrical structure, which is welded and fixed to the right end face of the rotating beam 17 to form an L shape. The reinforcing rib II 18 is a triangular steel plate, and the right-angled sides are welded and fixed to the rotating beam 17 and the support beam 19 respectively. The protective cover 20 is a tubular structure, the material is relatively soft, and it is put on the support beam 19 to protect the launcher 2 during hoisting.

[0036] The connection stop component 11 of the launcher hoisting device includes a fixing plate I 22, a fixing plate II 24, a stop pin 21, a bolt 23 and a nut 25; the fixing plate I 22 and the fixing plate II 24 are completely identical, and are fan-shaped structures, with a total of three groups of through holes, namely, E, F and G. The bolt 23 passes through the E hole of the fixing plate I 22, the A hole of the hanging beam II 13, and the E hole of the fixing plate II 24, and is fastened with a nut 25. The hanging beam II 13 fits tightly with the fixing plate I 22 and the fixing plate II 24 without any gap. The bolt 23 passes through the F hole of the fixing plate I 22, the B hole of the rotating beam 17, and the F hole of the fixing plate II 24, and is fixed with a nut 25. There is a gap of 2 to 3 mm between the rotating beam 17 and the fixing plate I 22 and the fixing plate II 24, and the rotating beam 17 can rotate around the bolt 23. The stop pin 21 passes through the G1 hole of the fixing plate I 22, the C hole of the rotating beam 17, and the G1 hole of the fixing plate II 24, or passes through the G2 hole of the fixing plate I 22, the D hole of the rotating beam 17, and the G2 hole of the fixing plate II 24, or passes through the G3 hole of the fixing plate I 22, the D hole of the rotating beam 17, and the G3 hole of the fixing plate II 24, so that the rotating beam 17 is stopped in the rotating direction. Different perforation stop modes can realize different angles of the rotating component 10, thereby realizing the hoisting of launchers 2 with different diameters.

[0037] In the specific implementation process, the further improved form can be: the fixing plate I 22 and the fixing plate II 24 in the connecting stop member 11 are completely identical, and the sizes and positions of the three groups of through holes E, F, and G are as follows: the four through holes in the E group are evenly distributed along the axial direction of the symmetry axis of the fixing plate, and the hole size and hole spacing are consistent with the through holes in the A group of the suspension beam II 13. The two through holes in the F group are symmetrically distributed on both sides of the symmetry axis of the fixing plate, and the hole diameter is consistent with the B hole of the rotary beam 17. The two through holes of G1 hole are symmetrically distributed on both sides of the symmetry axis of the fixed plate, and the distance between F hole and G1 hole on the same side of the symmetry axis of the fixed plate is consistent with the distance between B hole and C hole on the rotating beam 17; the two through holes of G2 hole are symmetrically distributed on both sides of the symmetry axis of the fixed plate, and the distance between F hole and G2 hole on the same side of the symmetry axis of the fixed plate is consistent with the distance between B hole and D hole on the rotating beam; the two through holes of G3 hole are symmetrically distributed on both sides of the symmetry axis of the fixed plate, and the distance between F hole and G3 hole on the same side of the symmetry axis of the fixed plate is consistent with the distance between B hole and D hole on the rotating beam; the apertures of G group through holes on the fixed plate are consistent with those of C hole and D hole on the rotating beam 17.

[0038] In addition, in some optional implementation cases, the stop pin 21 in the connecting stop component 11 includes a pin body 26, a stop block 27 and a cylindrical pin 28. The pin body 26 is a cylindrical structure with a step at one end and a notch at the other end, and a through hole in the vertical direction of the notch. The stop block 27 is a thin rectangular parallelepiped structure with a through hole at the center. The cylindrical pin 28 passes through the through holes of the pin body 26 and the stop block 27, and the stop block 27 is installed at the notch position of the pin body 26, and the stop block 27 can rotate freely in the notch. When the long side of the stop block 27 is along the direction of the notch of the pin body 26, the notch end of the pin body 26 can smoothly pass through the through holes of the fixed plate I 22, the slewing beam 17 and the fixed plate II 24; when the long side of the stop block 27 is perpendicular to the direction of the notch of the pin body 26, the notch end of the pin body 26 cannot pass through.

[0039] like Figure 4 As described above, the suspension beam component 12 is installed between the fixing plate I 22 and the fixing plate II 24 by using four bolts 23 and nuts 25 through the through holes of the A group and the E group. The two slewing components 10 are installed between the fixing plate I 22 and the fixing plate II 24 by using two bolts 23 and nuts 25 through the through holes of the B group and the F group, and the slewing components 10 can rotate around the bolts 23.

[0040] According to the diameter of the launcher 2, the C hole and the D hole on the rotating beam 17 and the corresponding through holes of the G group on the fixed plate are selected to adjust the opening angle of the two rotating parts 10. The stopper block 27 in the stopper pin 21 is moved so that the long side is along the direction of the notch of the pin body 26, and the stopper pin 21 is inserted from the corresponding through hole to limit the rotation of the rotating part 10; the stopper block 27 is moved again so that the long side is perpendicular to the direction of the notch of the pin body 26 to prevent the stopper pin 21 from falling off.

[0041] like Fig.10 As described, the support beam 19 equipped with the protective cover 20 is extended into the bottom of the launcher 2, and the position of the lifting ear Ⅰ16 on the lifting beam Ⅰ15 is adjusted so that the launcher 2 remains horizontal during the lifting process. The lifting device and the launcher 2 are lifted by the lifting ear Ⅰ16. The launcher 2 passes through the end faces of the front and rear hexagonal hollow structures of the fixing fixture 3 along with the support beam 19; the lifting beam Ⅰ15 and the lifting ear Ⅰ16 pass above the upper end face of the fixing fixture 3. When the lifting ear Ⅱ7 of the launcher 2 and the buckle 4 of the fixing fixture 3 are in the same vertical direction, lift it upward so that the lifting ear Ⅱ7 enters the buckle 4 and locks, and withdraw the lifting device to complete the lifting.

[0042] The present invention provides a new method for hoisting a transmitter to a fixed fixture during a transmitter test; the two rotating parts in the hoisting device are opened at different angles to realize the hoisting of transmitters with different diameters; the stop pin is used to realize the rapid and reliable stopping of the rotating part; the position of the lifting ear I on the lifting beam I is adjusted to realize the transmitter maintaining a horizontal state during the hoisting process. The problem that the original hoisting method requires close cooperation of multiple people, has low work efficiency, is easy to damage the product, and has personal safety risks is solved.

Any parts not described in detail are deemed to be conventional technical means or common knowledge in the field. It can be understood by ordinary technicians in this field that: based on the design concept of the present application, the technical solutions recorded in the aforementioned implementation methods should be adaptively modified, or some or all of the technical features therein should be replaced by equivalents.
