Description

Technical Field

[0001] The utility model belongs to the technical field of aerospace carrier equipment production, in particular to a first-stage tail cabin and booster docking vehicle. Background Art

[0002] Space launch technology is one of the fastest-growing modern science and technology, representing the ability of human beings to enter the outer space. As an important part of the development of aerospace technology, the launch vehicle is a vehicle that pushes various spacecraft manufactured by people into space. It is mainly composed of a rocket body, a power plant system and a control system. During the assembly process of the launch vehicle, the booster needs to be assembled to the first-stage tail cabin. This requires the operator to dock the two during assembly and always pay attention to the relative position of the two to ensure the accuracy of the assembly position. This operation method is heavily dependent on manual calibration, which is inconvenient to operate, labor-intensive and inefficient. Therefore, there is an urgent need for a device that can dock and position the first-stage tail cabin with the booster to simplify the operation, reduce the workload and improve work efficiency. Utility Model Content

[0003] In view of this, in order to solve the above-mentioned technical problems, the utility model proposes a first-stage tail cabin and booster docking vehicle with simple structure, low manufacturing cost, and convenient operation, which can effectively simplify the docking work, reduce workload, reduce assembly difficulty, and improve assembly efficiency.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] A first-stage tail cabin and booster docking vehicle, comprising:

[0006] A positioning tool plate, the positioning tool plate comprising an annular plate body and a clamping assembly arranged in the inner ring of the plate body for clamping the booster;

[0007] A mounting seat, on which the positioning tooling disc is rotatably mounted;

[0008] The bearing mechanism comprises a bearing frame for supporting the mounting seat and casters arranged at the bottom of the bearing frame.

[0009] The booster is fixed to the disc by a clamping assembly, and the disc is connected to the mounting base for relative rotation. The bearing mechanism moves the fixed booster to the first-stage tail cabin. Since the booster is fixed by the clamping assembly, no additional supporting force is required to support the booster. By rotating the disc, the docking position of the booster and the first-stage tail cabin is adjusted to achieve accurate docking between the first-stage tail cabin and the booster, reducing the workload of manual docking, making assembly easier and working more efficient.

[0010] Furthermore, the disc body includes two annular plates which are arranged in parallel and symmetrically in front and back, and a connecting column which connects and fixes the two annular plates.

[0011] Furthermore, the clamping assembly includes a support platform and a plurality of clamps; the support platform is fixed on the inner ring of the disk body, and the side of the support platform facing the center of the disk body is an arc-shaped surface; the end of the clamp facing away from the center of the disk body is telescopically connected to the disk body, and the side facing the center of the disk body is an arc-shaped surface.

[0012] When the booster is just put into the tray, it is supported by the support platform, and the clamp adjusts the telescopic length and then clamps to the surface of the booster to fix the booster. That is, the booster is clamped and fixed by the arc surface of the support platform and multiple clamps.

[0013] Furthermore, the clamp includes a connecting seat, a fixing sleeve, a connecting rod, and a clamping plate; the connecting seat is fixed to the disk body, and a socket is provided on the connecting seat, and the direction of the socket is consistent with the radial direction of the disk body; one end of the connecting rod is movably inserted into the socket and fixed to the connecting seat through the fixing sleeve, that is, the length of the connecting rod extending into the inner ring of the disk body is adjustable, thereby achieving clamping of the disk body, and the fixing sleeve can be detachably fixed to the connecting rod and the connecting seat by means of a threaded connection; the clamping plate is fixed to the other end of the connecting rod, and the side of the clamping plate facing the center of the disk body is an arc-shaped surface.

[0014] The booster is sent into the inner ring of the disc body and is first supported by the support platform. The fixing sleeve is unscrewed. At this time, the connecting rod and the connecting seat are in an unfixed state. The extension length of the connecting rod is adjusted to make the clamping plate fit tightly against the surface of the booster. Then the fixing sleeve is screwed on, the connecting rod and the connecting seat are fixed, the position of the clamp is fixed, and the booster is firmly fixed by the support platform and multiple clamps.

[0015] Furthermore, anti-skid cushion pads are provided on the curved surface of the support platform and the curved surface of the clamping plate to prevent the surface of the booster from being scratched.

[0016] Furthermore, there are two or three clamps; when there are two, the two clamps are equidistant from the support platform; when there are three, two of the clamps are symmetrically arranged, and the other one is symmetrically arranged with the support platform.

[0017] Furthermore, the mounting seat is a frame structure with an arc-shaped upper end, and a roller group is arranged along the arc at its upper end; the disk body is installed on the upper part of the mounting seat, and the outer edges of the two ring plates are adapted to the rollers of the roller group and can rotate relative to the roller group; a rotating handle is provided on the ring plate.

[0018] The disk body is inserted into the mounting seat near the outer edge and is rotatably connected to the mounting seat. When external force is applied to the rotating handle, the disk body rotates, and the outer edge of the disk body rotates relatively on the roller group, thereby realizing the rotation of the disk body.

[0019] Furthermore, a circle of sliding grooves is provided on the outer end surface of the ring plate along the circumferential direction, and a slide rail is provided on the upper end of the mounting seat, which is buckled in the sliding groove and can slide relatively along the sliding groove.

[0020] When the disc body rotates, the slide rail on the mounting seat rotates in the slide groove of the ring plate to guide and stabilize the disc body.

[0021] Furthermore, the bearing frame includes a support frame with the casters at the bottom, a lifting rod installed on the support frame and fixed to the mounting seat, and an adjusting hand wheel for adjusting the lifting and lowering of the fixed lifting rod.

[0022] The height of the lifting rod is adjusted by the hand wheel, thereby adjusting the height of the mounting base and the disc body, and then adjusting the height of the clamped booster to better dock the booster with the first-stage tail cabin.

[0023] Furthermore, the lifting rod is a screw structure, and its screw nut is rotatably connected to the support frame through a rotating bearing, the adjusting handwheel is connected to the screw nut, and the top of the lifting rod is fixed to the mounting seat.

[0024] The lead screw nut is connected to the support frame through a rotating bearing. The rotation of the lead screw nut does not affect the support frame. When the hand wheel is turned, the lead screw nut rotates, and the lifting rod of the lead screw structure rises and falls.

[0025] Compared with the prior art, the first-stage tail cabin and booster docking vehicle described in the utility model has the following advantages:

[0026] (1) The first-stage tail cabin and booster docking vehicle of the utility model has a simple structure and low manufacturing cost. The booster is fixed on the disc body by a clamp to play a supporting and fixing role. The booster is moved to a suitable position by a bearing mechanism, and the docking surface of the booster is adjusted by rotating the disc body to achieve accurate docking of the first-stage tail cabin and the booster, reducing the workload of manual docking, simplifying the docking work, making it easier to assemble, and improving work efficiency;

[0027] (2) The carrier described in the utility model can be raised and lowered in height, thereby optimizing the docking accuracy between the booster and the first-stage tail cabin, facilitating adjustment, reducing assembly difficulty, and providing greater adaptability.
