Other embodiments will be apparent to those skilled in the art from consideration of the specification. The specification and examples are exemplary only.
One aspect of the utility model provides a frock for supporting rocket engine installation. As shown in fig. 1, 2 and 8, the tool includes first columns 1 uniformly arranged along the circumferential direction, and a connecting structure connecting adjacent first columns 1. Wherein, connection structure contains spliced pole 3 and is located the connecting piece 2 at spliced pole 3 both ends, and the connecting piece 2 other end is connected with first stand 1. The spliced pole 3 contains first outer post 4, second outer post 5 and interior post 6, and first outer post 4 and second outer post 5 set up at the both ends of 6 length direction of interior post, and first outer post 4 and second outer post 5 can be followed the outer wall of interior post 6 and movable. On the length direction of interior post 6, first outer post 4, second outer post 5 and interior 6 surfaces of post are equipped with corresponding fixed orifices 7, and the fixed orifices 7 of different positions is through cooperating with mounting 8 for adjust the distance between first outer post 4 and the second outer post 5.
Specifically speaking, this kind of frock for supporting rocket engine installation comprises first stand 1 and connection structure. Because first outer post 4 and second outer post 5 can freely remove along the outer wall of inner prop 6, can realize finely tuning the distance between adjacent first stand 1 through adjusting the distance between first outer post 4 and the second outer post 5 to make the installing support get into rocket inside smoothly. The fixed orifices 7 are matched with the fixing piece 8, so that the distance between the first outer column 4 and the second outer column 5 can be conveniently adjusted, the first outer column 4 and the second outer column 5 can be effectively fixed, the displacement movement between the first outer column 4 and the second outer column 5 is avoided, and the whole tool can be safe and stable in the working state. The whole structure has the advantages of convenient operation, safety, reliability and capability of improving the efficiency.
In the present embodiment, in order to facilitate the connection of the connecting member 2 with the first upright 1 and the connecting column 3, the connecting member 2 has an elbow structure, one end of the connecting member is connected with the connecting column 3 through a fixing bolt, and the other end of the connecting member is provided with a concave portion, and the concave portion is closely attached to the surface of the first upright 1 and is welded to the first upright.
It should be noted that, as shown in fig. 1 and fig. 2, in order to facilitate fine adjustment of the distance between adjacent first vertical posts 1 and reduce the weight of the bracket, for example, the first outer post 4, the second outer post 5 and the inner post 6 are all of cylindrical structures with two ends communicated and a hollow interior. In the application process, in order to enlarge the use space and facilitate the installation of operators, for example, the cylindrical structure is provided with a curved arc (the curved arc is a structure which is concave towards one side far away from the center consisting of the plurality of first upright posts 1).
As shown in fig. 1, in order to facilitate adjustment of the movement between the first outer column 4 and the second outer column 5, for example, center lines of the first outer column 4, the second outer column 5, and the inner column 6 in the circumferential direction formed by the plurality of first upright columns 1 coincide with each other.
As shown in fig. 1, 3, 4, 5, and 6, in use, in order to facilitate adjustment of the movement of the first outer column 4 and the second outer column 5 along the inner column 6 and avoid the first outer column 4 and the second outer column 5 from shifting during the movement, for example, the inner wall surfaces of the first outer column 4 and the second outer column 5 near each other are respectively provided with a fixing block 9, the fixing block 9 is provided with a slot 10 formed along the extending direction of the two ends of the center line (i.e., the direction of bending arc), and the outer surface of the inner column 6 is provided with a protruding strip 11 for fitting the slot 10. In the process that the two outer columns move along the inner column 6, the grooves 10 and the protruding strips 11 are matched with each other, and the motion guiding and limiting effects are achieved on the first outer column 4 and the second outer column 5. The protruding strip 11 removes along 10 inner walls of fluting, guarantees that first outer post 4 and second outer post 5 remove smoothly along the outer wall of inner prop 6, avoids taking place to rock between two outer posts and the inner prop 6 simultaneously, has improved the accurate cooperation of fixed orifices 7 and mounting 8 in the follow-up interior outer post connection operation.
It should be noted that, if the outer column can't realize the accurate motion along the outer wall of inner column 6, the deviation can appear in the transverse position relation of interior outer column, and then can't realize the accurate cooperation of the fixed orifices of inner column 6 and the mounting of outer column, at this moment, need adjust inner column 6, make the fixed orifices of inner column 6 concentric with the mounting that first outer column 4 corresponds, thereby lead to first outer column 4 and second outer column 5 complex operation when being connected with inner column 6, work efficiency when reducing the frock support engine installation.
In the present embodiment, in order to prevent the fixed block from moving, for example, the fixed block 9 is welded to the inner wall of the first outer column 4 and the fixed block 9 is welded to the inner wall of the second outer column 5
In order to make the protruding strip 11 and the inner column 6 tightly connected, the fixation is firm, for example, the protruding strip 11 and the inner column 6 are tightly attached to each other and connected by welding.
In the present embodiment, in order to reduce the weight of the entire tool, the number of the fixing blocks 9 on the first outer column 4 and the second outer column 5 may be two, for example, without affecting the use effect.
As shown in fig. 1 and 7, in the fine adjustment process of the adjacent first upright 1, in order to accurately adjust the distance between the first outer column 4 and the second outer column 5 and to facilitate recording for use next time, for example, a scale mark 12 is provided on the surface of the inner column 6, when the distance between the adjacent first upright needs to be fine-adjusted, the first outer column 4 and the second outer column 5 can be moved along the surface of the inner column 6, and the actual moving distance of the first outer column 4 and the second outer column 5 can be accurately recorded by observing the scale on the surface of the inner column, so that the whole tool can be accurately adjusted.
It should be further noted that, in application, the fixture of the present application penetrates through the fixing holes through the fixing members to fix the first outer column 4 and the second outer column 5. In order to ensure the stable structure of the connecting column 3 and reduce errors, for example, an internal thread is arranged on the fixing hole 7, the fixing piece 8 is a bolt with an external thread, and the fixing hole 7 is in threaded connection with the fixing piece 8, so that the fixing piece 8 is ensured to be fixed firmly.
The foregoing is only an illustrative embodiment of the present invention, and any equivalent changes and modifications made by those skilled in the art without departing from the spirit and principles of the present invention should fall within the protection scope of the present invention.
