[0002] In the field of space launch, the erection cylinder is needed during the erection process of the launch tube. The erection cylinder needs to be fixed to the launch tube and the launch frame. During the process of connecting the erection cylinder to the launch tube, the pin hole of the erection cylinder needs to be accurately positioned with the pin hole on the launch tube. This requires the position of the erection cylinder to be constantly adjusted. Since the weight of the erection cylinder is generally around 2 tons, it is impossible to use manpower to center the pin hole. Multiple hoisting methods are often used to adjust the position and achieve pin hole centering. Due to the limited hoisting accuracy and the shaking during the hoisting process, this method of centering usually takes a long time, resulting in great difficulty in pin hole centering. At the same time, there are also problems such as high labor intensity, low efficiency, easy damage to the erection cylinder, and high risk factor of on-site operation. Utility Model Content

[0024] Specifically, a hinge seat 51 is provided on the erecting frame 5, one end of the erecting arm 4 is a free end, and the other end is hinged to the hinge seat 51 as a connecting end, and the middle part of the erecting arm is used to assemble a erecting cylinder to enable the erecting arm 4 to flip around the hinge seat 51 as the center.

[0025] A connecting piece is fixed in the middle position of the erecting arm 4, and a first connecting pin hole is opened on the connecting piece. A connecting hole matching with the first connecting pin hole is opened on one end of the movable connecting rod 31. After the first connecting pin hole matches with the corresponding connecting hole, a first pin shaft is passed through for connection. The movable connecting rod 31 can be flipped relative to the erecting arm 4 with the first pin shaft as the rotation axis to increase or decrease the angle between the two.

[0026] A connecting base 52 is provided on the main body of the erecting frame 5 between the erecting arm 4 and the movable support assembly, and a second connecting pin hole is opened on the connecting base 52. A connecting hole matching the second connecting pin hole is opened on the other end of the movable connecting rod 31. The second connecting pin hole is connected to the corresponding connecting hole through which a second pin shaft is passed. The movable connecting rod 31 can be flipped with the second pin shaft as the rotation axis.

[0027] The height of the roller support 3 is higher than the connecting base 52, and the roller support 3 can translate on the erecting frame 5. When the angle between the erecting arm 4 and the erecting frame is acute, the projection of the erecting arm 4 just falls on the translation path of the roller support 3. When the roller support 3 translates, it can move in a straight line along the movable connecting rod 31, and when the roller support 3 is close to the connecting base 52, the free end of the movable connecting rod 31 is supported and lifted, and when the roller support 3 is away from the connecting base, the free end of the movable connecting rod 31 falls.

[0028] In this embodiment, the mobile support assembly also includes a support 1 and a driving mechanism 2. The support 1 is fixed on the erecting frame 5, and a linear track 1a is also provided thereon; the driving mechanism 2 is fixed on the support 1 at one end of the linear track 1a away from the erecting arm 4, and the roller support 3 is provided on the linear track 1a and connected to the driving mechanism 2 through a rotating connecting member 21. The driving mechanism 2 is used to drive the rotating connecting member 21 to rotate so as to drive the roller support 3 to translate along the linear track 1a.

[0029] Specifically, Figure 2 As shown, the bracket 1 has a rectangular platform, and the linear rails 1a include two, and the two linear rails are fixed in parallel on the rectangular platform by screw connection. The driving mechanism 2 is centrally fixed on one end of the two linear rails 1a away from the erection arm 4. The roller support 3 is installed on the linear rail 1a and is located on the linear rail 1a between the driving mechanism 2 and the erection arm 4. The two ends of the rotating connection 21 are respectively connected to the roller support 3 and the driving mechanism 2. The driving mechanism 2 can drive the rotating connection 21 to rotate, so that the roller support 3 moves along the rotating connection 21 along the linear rail 1a.

[0030] In this embodiment, the aforementioned rotating connecting member 21 is a screw, which can specifically be a trapezoidal screw 2e. A screw nut 3a is also provided on the base 32 body. The screw nut 3a is fixed to the base between the two rollers by bolt connection. One end of the screw is passed through and connected to the screw nut 3a. When the driving mechanism 2 drives the screw to rotate, the screw and the screw nut 3a drive the base 2 to slide back and forth stably along a straight line through threaded cooperation, thereby realizing the stepless adjustment of the height of the free end of the movable connecting rod 31, and then realizing the stepless and stable adjustment of the height between the vertical arm and the horizontal plane.

[0031] In this embodiment, a slide groove parallel to the erecting arm 4 is provided on the erecting arm 4, and the roller 3b abuts against the slide groove. Combined with the linear track 1a, the slide groove and the roller 3b can further make the translation movement of the roller support 3 stable and reliable.

[0032] In this embodiment, Figure 3 As shown, the aforementioned driving mechanism 2 includes a reducer 2d, a sprocket 2c, a transmission chain 2b and a handwheel 2a, the sprocket 2c includes a first sprocket and a second sprocket arranged in the same plane, the output end of the reducer is connected to the other end of the rotating connecting member 21, and its input end is matched with the first sprocket, the first sprocket and the second sprocket are fixed on the reducer 2d, and the transmission chain 2b is meshed with the first sprocket and the second sprocket to form a transmission structure; the axis of the second sprocket is fixedly connected to the handwheel 2a, and the handwheel 2a can drive the second sprocket to rotate around its own axis.

[0033] Specifically, a bracket is fixed on the top surface of the reducer 2d, and the second sprocket and the handwheel 2a are rotatably fixed on both sides of the bracket respectively. The first sprocket is fixed to the side of the reducer 2d directly below the second sprocket. The transmission chain 2b is meshed and assembled with the first sprocket and the second sprocket to form a transmission structure. By rotating the handwheel 2a, the trapezoidal lead screw 2e is driven to rotate, and then the movable support 3 is driven to move left and right through the lead screw nut 3a. The roller 3b rolls along the movable connecting rod, thereby driving the erection arm to rise or fall, and finally realizing the rotational movement of the erection arm 5.

[0037] In this embodiment, a limit block (not shown in the figure) is further provided at one end of the rotating connecting member 21 close to the roller support 3 to prevent the roller support 3 from being too close to the driving mechanism, resulting in an excessively large vertical angle of the vertical cylinder, thereby ensuring that the angle between the vertical cylinder and the horizontal plane is within a safe range.

[0038] In this embodiment, Figure 5 As shown, the movable connecting rod 31 includes two parallel supporting beams 4b, a connecting plate 4c is connected between the two supporting beams 4b, and one end of the supporting beams 4b is hinged to the erecting frame 5 respectively; each supporting beam is provided with a slide groove, and the rollers 3b are respectively abutted against the corresponding slide grooves, so as to achieve more stable relative movement; specifically, the aforementioned slide groove is a V-shaped slide groove.

[0039] In this embodiment, Figure 5 As shown, a polytetrafluoroethylene pad 4a is also provided on the erecting arm 4 to prevent excessive sliding friction between the erecting cylinder and the erecting arm 4 during the supporting process, thereby preventing the erecting cylinder assembled on the erecting arm 4 from being damaged during the lifting process.

[0040] The utility model can realize the rapid alignment and docking of the vertical cylinder and the target pin hole without special lifting equipment and crane, reduces the requirements for operators and operating space, improves work efficiency, and has the characteristics of convenient and fast operation and high safety.
