[0012] Compared with the prior art, the technical solution of the present application has at least the following beneficial technical effects: 1. The present application sets a flip support structure, wherein the supporting side plate and the supporting bottom plate are respectively provided with a first supporting surface and a second supporting surface, that is, an L-shaped structure is formed. When the propellant shell is placed between the supporting bottom plate and the supporting side plate with the axis parallel to the first supporting surface and perpendicular to the second supporting surface, the propellant shell is supported in the axial and radial directions by the supporting bottom plate and the supporting side plate respectively, and the propellant shell is clamped by the clamping mechanism on the supporting side plate to fix it. When flipping the propellant shell, the flip support structure is first driven by the flip driving cylinder to rotate to the level of the second supporting surface, then the first supporting surface is vertical, one end of the propellant shell is placed on the supporting bottom plate, and the propellant shell is clamped by the hijacking mechanism to fix it, and then the flip support structure is driven by the flip driving cylinder to rotate to the horizontal state of the first supporting surface.

The propellant casing is supported axially and radially during the flipping process and remains fixed, so that the flipping work can be completed quickly and with reduced risks.

[0013] 2. The present application forms a clamping mechanism through two clamping arms and multiple product support seats. The arc groove on the product support seat is set so that when the propellant shell is placed on the support base plate, the side wall of the propellant shell is embedded in the arc groove, and the two clamping arms are rotated to abut against the propellant shell. The two clamping arms press the propellant shell onto the product support seat. Under the restriction of the arc groove and the two clamping arms, the propellant shell is restricted to move in the radial direction, thereby fixing the propellant shell. The fixing method is simple and has a good fixing effect, so as to avoid the risk caused by the movement of the propellant shell during the flipping process.

[0014] 3. The present application supports the propellant shell by setting up a support plate. The support plate is designed according to the propellant shell structure so that the propellant shell can be stably placed on the support plate. The support plate can be moved close to or away from the supporting side plate in a direction perpendicular to the first supporting surface. In the process of hoisting the propellant shell onto the flip support structure, the support plate can be moved away from the supporting side plate first to provide sufficient space for the hoisting of the propellant shell; after the propellant shell is hoisted onto the support plate and fixed, the support plate is moved close to the supporting side plate, so that the propellant shell is moved into the arc groove embedded in the product support seat, and is pressed and fixed by the clamping arm.

[0015] 4. The present application sets multiple bottom plate support seats, side plate support frames and multiple side plate support seats. When the flip support structure rotates to the level of the second support surface, the support bottom plate is located above the bottom plate support seat, and the support bottom plate is supported by the multiple bottom plate support seats. When the flip support structure rotates to the level of the first support surface, the support side plate is located above the side plate support seat, and the support side plate is supported by the multiple side plate support seats. This can prevent the flip drive cylinder from being always under stress and increase its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference Figure 1-2 and Figure 5-6 As shown, a clamping mechanism 4 for clamping the propellant shell is provided on the support side plate 21. The propellant shell is suitable for being placed between the support base plate 22 and the support side plate 21 with the axis parallel to the first support surface 211 and perpendicular to the second support surface 221. The support base plate 22 and the support side plate 21 are respectively used to support the propellant shell in the axial direction and the radial direction. The clamping mechanism 4 is used to clamp the propellant shell to limit the movement of the propellant shell.

[0025] Reference Figure 1-2 As shown, specifically, the structure of the frame 1 is designed according to the actual support needs so that it has sufficient structural strength to stably support the flip mechanism. The first support surface 211 has a longer length in a direction perpendicular to the first axis to ensure that the propellant shell can be stably supported. The support side plate 21 is hinged to the frame 1 at one end in the length direction of the first support surface 211, and the support bottom plate 22 is connected to the hinged end of the support side plate 21 and the frame 1. The body of the flip drive cylinder 3 is hinged to the frame 1, and the piston rod is hinged to the end of the support side plate 21 away from the support bottom plate 22, so that the force application point of the flip drive cylinder 3 on the support side plate 21 is far away from the hinge axis, and the force required to drive the support bottom plate 22 can be reduced according to the lever principle.

[0026] Reference Figure 1-2As shown, in order to realize the function of the clamping structure to clamp the propellant shell, the clamping mechanism 4 includes two clamping arms 41 connected to the first support surface 211 and a plurality of product support seats 42. The two clamping arms 41 are connected and spaced along the first axis direction, and the clamping arms 41 can rotate around an axis perpendicular to the second support surface 221. The product support seat 42 is located between the two clamping arms 41, and the plurality of product support seats 42 are spaced along a direction perpendicular to the support base plate 22. The side of the product support seat 42 away from the first support surface 211 is provided with an arc groove for the propellant shell to be embedded. Among them, the clamping arm 41 can be rotated to abut against the propellant shell embedded in the arc groove, and is suitable for pressing the propellant shell onto the plurality of product support seats 42 through the two clamping arms 41 when the propellant shell is embedded in the arc groove.

[0027] Reference Figure 2-3As shown, specifically, the clamping arm 41 is connected to the first support surface 211 through a clamping drive structure, and the clamping drive structure includes a base 43 fixed on the first support surface 211. The two ends of the clamping arm 41 are spaced apart in the direction of the first axis, and the middle of the clamping arm 41 is hinged to the base 43, and the hinge axis is parallel to the first axis. A movable link 44 is connected to one end of the clamping arm 41 away from the product support seat 42, and one end of the movable link 44 is hinged to the support arm, and the other end is connected to a fixed link 45, and one end of the fixed link 45 is hinged to the movable link 44, and the other end is hinged to the base 43. A clamping drive oil cylinder 46 is provided between the fixed link 45 and the base 43, and the body and piston rod of the clamping drive oil cylinder 46 are respectively hinged to the base 43 and the fixed link 45, and the above-mentioned hinge axes are parallel to the first axis. A connecting rod mechanism is formed by a fixed connecting rod 45 and a movable connecting rod 44. During design, when the piston rod of the clamping driving cylinder 46 is extended, the fixed connecting rod 45 is driven to rotate, the fixed connecting rod 45 drives the movable connecting rod 44 to rotate, and the movable connecting rod 44 drives the clamping arm 41 to rotate, so that the end of the clamping arm 41 away from the telescopic rod rotates close to the propellant shell embedded in the arc groove; conversely, when the piston rod of the clamping driving cylinder 46 is contracted, the end of the clamping arm 41 away from the telescopic rod is driven by the fixed connecting rod 45 and the movable connecting rod 44 to move away from the propellant shell. In addition, a limit rod 47 is fixed on the base 43, and the limit rod 47 is located on the side of the fixed link 45 away from the product support seat 42. The axis of the limit rod 47 is perpendicular to the first axis and parallel to the first support surface 211. When the piston rod of the clamping drive cylinder 46 is extended to drive the fixed link 45 to rotate, when the piston rod of the clamping drive cylinder 46 is extended to the maximum length, the fixed link 45 and the limit rod 47 are abutted, and at this time, the angle formed by the axis of the movable link 44 and the axis of the fixed link 45 close to the product support seat 42 is less than 180°. At this time, when the clamping arm 41 is subjected to the force of the propellant shell and rotates away from the propellant shell, the force applied by the clamping arm 41 to the fixed link 45 through the movable link 44 acts on the limit rod 47 instead of the clamping drive cylinder 46, thereby protecting the clamping drive cylinder 46 and ensuring that the clamping arm 41 fixes the propellant shell to prevent the product from overturning.

[0028] Reference Figure 3As shown, in order to enable the clamping arm 41 to clamp propellant shells of different diameters, the movable link 44 is set as a telescopic structure. Specifically, the movable link 44 includes two coaxial connecting tubes 441, and the two connecting tubes 441 are connected by an adjusting screw 442. The two ends of the adjusting screw 442 are respectively inserted into the two connecting tubes 441, and the adjusting screw 442 is threadedly connected to the two connecting tubes 441. Therefore, the two connecting tubes 441 can be moved closer to or away from each other by rotating the adjusting screw 442, so that the movable link 44 can be extended or shortened. When the fixed link 45 is rotated to abut against the limit rod 47, the distance between the end of the clamping arm 41 that contacts the propellant shell and the product support seat 42 can be adjusted by adjusting the length of the movable link 44. In actual application, according to the specifications of the flipped propellant shell, the length of the movable link 44 is adjusted until the end of the clamping arm 41 in contact with the propellant shell just forms an abutment with the product support seat 42 when the fixed link 45 is rotated to abut against the limit rod 47, so that the propellant shell can be stably pressed against the product support seat 42 by the clamping arm 41, and the propellant shell can be fixed in place by cooperating with the product support seat 42.

[0029] Reference Figure 2-3 As shown, in order to prevent the clamping arm 41 from damaging the surface of the propellant shell, an arc-shaped clamping plate 48 is provided at the end of the clamping arm 41 that contacts the propellant shell, and the inner concave surface of the clamping plate 48 is used to contact the propellant shell, and a polyurethane pad and wool felt are provided on the inner concave surface of the clamping plate 48.

The propellant shell is suitable for being placed on the support plate 7 with the axis and the third support surface perpendicular to each other, and the support plate 7 is used to be fixed to the propellant shell. Specifically, the support plate 7 is set to be a disc shape with the axis and the second support surface 221 perpendicular to each other, and a positioning seat 71 adapted to the end hole of the propellant shell is provided in the middle of the support plate 7. When the propellant shell is placed on the support plate 7, the positioning seat 71 passes through the end hole of the propellant shell to position and limit the radial movement of the propellant shell.

[0033] In order to have enough space to hoist the propellant shell onto the positioning plate, the positioning plate can be moved close to or away from the supporting side plate 21 in a direction perpendicular to the first supporting surface 211. The positioning plate can be moved by the cooperation of the guide rail and the slider between the positioning plate and the supporting bottom plate 22, and a cylinder or oil cylinder is provided to drive the positioning plate to move. When hoisting the propellant shell onto the positioning plate, the positioning plate is moved to a position far from the supporting side plate 21 to avoid accidents such as collision between the propellant shell and the positioning side plate during the hoisting process. After the hoisting is completed, the positioning plate is moved close to the supporting side plate 21 until the propellant shell is embedded in the arc groove of the product support seat 42.

Specifically, the top surface of the bottom plate support seat 8 is set as a horizontal plane, so that the bottom plate support seat 8 can stably support the bottom plate 22, and when the second support surface 221 is horizontal, the bottom plate support seat 8 bears the gravity of the bottom plate 22 and the propellant shell thereon, so as to avoid the flip drive oil cylinder 3 being in a working state all the time and affecting the service life.

The side panel support seat 91 is used to support the supporting side panel 21 below the supporting side panel 21 when the flip support structure 2 rotates to the level of the first supporting surface 211. Similarly, the top surface of the side panel support seat 91 is set as a horizontal plane, so that the supporting side panel 21 can be stably supported by the side panel support seat 91. When the first supporting surface 211 is horizontal, the side panel support seat 91 bears the gravity of the supporting side panel 21 and the propellant shell thereon, so as to avoid the flip driving oil cylinder 3 being in a working state all the time and affecting the service life.

When the flip support structure 2 rotates toward the horizontal state of the first support surface 211, the support side plate 21 first contacts the vibration damping seat 101, and the vibration damping seat 101 descends to compress the vibration damping spring 102, and the vibration damping device 10 plays a vibration damping role to avoid the support side plate 21 and the side plate support plate from rigidly colliding and causing damage to the propellant shell.
