Description

Technical Field

[0001] This invention relates to the technical field of auxiliary equipment for transporting large workpieces, and specifically to an automatic product flipping device. Background Technology

[0002] In the solid fuel propellant industry, after the propellant casing is demolded, it is generally necessary to flip it over to change its position from vertical to horizontal, facilitating loading and transportation. Current propellant flipping devices typically employ manual double-hook lifting or screw-type flippers. For large-tonnage, large-volume solid propellant casings, this method is inefficient and carries significant risks. Summary of the Invention

[0003] Based on the above description, the present invention provides an automatic product flipping device to solve the problems of low flipping efficiency and high risk of large-tonnage, large-volume solid propellant shells.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0005] This application provides an automatic product flipping device, the technical solution of which is as follows:

[0006] An automatic product flipping device includes:

[0007] frame;

[0008] A tilting mechanism mounted on the frame includes a tilting support structure and a tilting drive cylinder. The tilting support structure includes a support side plate and a support bottom plate connected to each other. The support side plate has a first support surface, and the support bottom plate has a second support surface perpendicular to the first support surface. The tilting support structure can rotate relative to the frame about a horizontal first axis. The first axis is parallel to both the first and second support surfaces. The tilting drive cylinder body and piston rod are respectively hinged to the tilting support structure and the frame. The tilting drive cylinder body is used to drive the tilting support structure to rotate about the first axis.

[0009] The support side plate is provided with a clamping mechanism for clamping the propellant shell. The propellant shell is adapted to be placed between the support base plate and the support side plate in an orientation where its axis is parallel to the first support surface and perpendicular to the second support surface. The support base plate and the support side plate are respectively used to support the propellant shell in the axial and radial directions. The clamping mechanism is used to clamp the propellant shell to restrict the movement of the propellant shell.

[0010] Preferably, the clamping mechanism includes:

[0011] Two clamping arms are connected to the first support surface, and the two clamping arms are spaced apart along the first axis. The clamping arms can rotate about an axis parallel to the first axis.

[0012] Multiple product support seats are connected to the first support surface. The product support seats are located between the two clamping arms. The multiple product support seats are spaced apart along a direction perpendicular to the support base plate. The side of the product support seat away from the first support surface is provided with an arc-shaped groove for the propellant shell to be embedded.

[0013] The clamping arm is rotatable to abut against the propellant housing embedded in the arc-shaped groove, and is adapted to press the propellant housing onto the plurality of product support seats by the two clamping arms when the propellant housing is embedded in the arc-shaped groove.

[0014] Preferably, the support base plate is provided with a support disk located on the second support surface, the support disk includes a third support surface parallel to the second support surface, the propellant shell is adapted to be placed on the support disk in an attitude perpendicular to the axis and the third support surface, and the support disk is used to fix the propellant shell.

[0015] Preferably, the support plate can move closer to or further away from the support side plate in a direction perpendicular to the first support surface.

[0016] Preferably, the frame is provided with a plurality of base plate support seats, and the support base plate is located above the base plate support seats when the second support surface is horizontal. The base plate support seats are used to support the support base plate below the support base plate when the flip support structure is rotated to the second support surface being horizontal.

[0017] Preferably, the frame is provided with a movable support plate, the upper surface of the movable support plate is horizontal, and the support base plate is located directly above the movable support plate when the second support surface is horizontal. The movable support plate can be raised and lowered vertically and can be raised and lowered until its upper surface is flush with the second support surface in the horizontal state.

[0018] Preferably, it further includes a side plate support frame, the side plate support frame and the frame are distributed at intervals in the horizontal direction along a direction perpendicular to the first axis, the side plate support frame is provided with a plurality of side plate support seats, the support side plate is located above the side plate support seat when the first support surface is horizontal, and the side plate support seat is used to support the support side plate below the support side plate when the flip support structure is rotated to the first support surface being horizontal.

[0019] Preferably, the side plate support frame is provided with multiple vibration damping devices. When the support side plate is in a horizontal state, it is located above the side plate support seat. The vibration damping device includes a vibration damping seat, which is elliptical and rotatable on the side plate support frame. The vibration damping seat can be moved until its top height is lower than the top height of the side plate support seat. A vibration damping spring is provided between the vibration damping seat and the side plate support frame. When the vibration damping seat moves downward, it overcomes the elastic force of the vibration damping spring.

[0020] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects:

[0021] 1. This application employs a flipping support structure, wherein the support side plate and support base plate are respectively provided with a first support surface and a second support surface, forming an L-shaped structure. When the propellant shell is placed between the support base plate and the support side plate with its axis parallel to the first support surface and perpendicular to the second support surface, the support base plate and support side plate support the propellant shell axially and radially, respectively, and the clamping mechanism on the support side plate clamps the propellant shell to fix it. When flipping the propellant shell, the flipping support structure is first driven by a flipping drive cylinder to rotate until the second support surface is horizontal, then the first support surface is vertical. One end of the propellant shell is placed on the support base plate and clamped and fixed by the clamping mechanism. Then, the flipping support structure is driven by the flipping drive cylinder to rotate to the horizontal state of the first support surface. During the rotation, the support base plate and support side plate support the propellant shell axially and radially, and the propellant shell remains fixed during the flipping process under the clamping mechanism until the flipping support structure rotates to the horizontal state of the first support surface, completing the flipping action. The propellant casing is supported axially and radially during the flipping process and remains fixed, thus enabling the flipping operation to be completed quickly and reducing risks.

[0022] 2. This application utilizes two clamping arms and multiple product support seats to construct a clamping mechanism. The arc-shaped grooves on the product support seats allow the propellant casing's sidewalls to embed into the grooves when placed on the support base plate. The two clamping arms rotate to abut against the propellant casing, pressing it firmly against the product support seats. Under the constraint of the arc-shaped grooves and the two clamping arms, the propellant casing is restricted to radial movement, thus fixing it in place. This fixing method is simple and provides good stability, avoiding the risks associated with movement during propellant casing rotation.

[0023] 3. This application uses a support plate to support the propellant shell. The support plate is designed according to the structure of the propellant shell so that the propellant shell can be stably placed on the support plate. The support plate can move closer to or away from the support side plate in a direction perpendicular to the first support surface. During the process of hoisting the propellant shell onto the flip support structure, the support plate can be moved away from the support side plate first to provide sufficient space for hoisting the propellant shell. After the propellant shell is hoisted onto the support plate and fixed, the support plate is moved closer to the support side plate to move the propellant shell into the arc-shaped groove embedded in the product support seat, and then clamped and fixed by the clamping arm.

[0024] 4. This application, by setting multiple base plate support seats, side plate support frames, and multiple side plate support seats, ensures that when the tilting support structure rotates to the second support surface level, the support base plate is located above the base plate support seats and supported by the multiple base plate support seats. Similarly, when the tilting support structure rotates to the first support surface level, the support side plates are located above the side plate support seats and supported by the multiple side plate support seats. This avoids the tilting drive cylinder being constantly under stress, thus improving its service life. Attached Figure Description

[0038] Reference Figure 1-6 As shown, this application embodiment provides an automatic product flipping device, including a frame 1 and a flipping mechanism. The flipping mechanism is mounted on the frame 1 and includes a flipping support structure 2 and a flipping drive cylinder 3. The flipping support structure 2 includes a support side plate 21 and a support base plate 22 connected to each other. The support side plate 21 is provided with a first support surface 211, and the support base plate 22 is provided with a second support surface 221 perpendicular to the first support surface 211. The flipping support structure 2 can rotate relative to the frame 1 around a horizontal first axis. The first axis is parallel to both the first support surface 211 and the second support surface 221. The body and piston rod of the flipping drive cylinder 3 are hinged to the flipping support structure 2 and the frame 1, respectively. The body of the flipping drive cylinder 3 is used to drive the flipping support structure 2 to rotate around the first axis.

[0039] Reference Figure 1-2 and Figure 5-6 As shown, the support side plate 21 is provided with a clamping mechanism 4 for clamping the propellant shell. The propellant shell is adapted to be placed between the support base plate 22 and the support side plate 21 in an orientation that is parallel to the axis and 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 used to support the propellant shell in the axial and radial directions, respectively. The clamping mechanism 4 is used to clamp the propellant shell to restrict the movement of the propellant shell.

[0040] Reference Figure 1-2 As shown, specifically, the frame 1 structure is designed according to actual support needs, giving it sufficient structural strength to stably support the tilting mechanism. The first support surface 211 has a relatively long length in the direction perpendicular to the first axis to ensure stable support of the propellant shell. One end of the support side plate 21 along the length of the first support surface 211 is hinged to the frame 1, while the support base plate 22 is connected to the hinged end of the support side plate 21 and the frame 1. The body of the tilting 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 base plate 22, so that the point of force application of the tilting drive cylinder 3 to the support side plate 21 is far from the hinge axis. According to the lever principle, this reduces the force required to drive the support base plate 22.

[0041] Reference Figure 1-2As shown, to achieve the function of clamping the propellant casing, the clamping mechanism 4 includes two clamping arms 41 connected to the first support surface 211 and multiple product support seats 42. The two clamping arms 41 are connected and spaced apart along the first axis, and the clamping arms 41 can rotate about an axis perpendicular to the second support surface 221. The product support seats 42 are located between the two clamping arms 41, and the multiple product support seats 42 are spaced apart 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-shaped groove for the propellant casing to be embedded. The clamping arms 41 can rotate to abut against the propellant casing embedded in the arc-shaped groove, which is suitable for pressing the propellant casing onto the multiple product support seats 42 by the two clamping arms 41 when the propellant casing is embedded in the arc-shaped groove.

[0042] Reference Figure 2-3As shown, specifically, the clamping arm 41 is connected to the first support surface 211 via a clamping drive structure. 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 along the first axis. The middle part of the clamping arm 41 is hinged to the base 43, and the hinge axis is parallel to the first axis. A movable connecting rod 44 is connected to the end of the clamping arm 41 away from the product support base 42. One end of the movable connecting rod 44 is hinged to the support arm, and the other end is connected to a fixed connecting rod 45. One end of the fixed connecting rod 45 is hinged to the movable connecting rod 44, and the other end is hinged to the base 43. A clamping drive cylinder 46 is provided between the fixed connecting rod 45 and the base 43. The body and piston rod of the clamping drive cylinder 46 are respectively hinged to the base 43 and the fixed connecting rod 45. All the hinge axes are parallel to the first axis. A linkage mechanism is formed by a fixed link 45 and a movable link 44. In the design, when the piston rod of the clamping drive cylinder 46 extends, it drives the fixed link 45 to rotate. The fixed link 45 drives the movable link 44 to rotate, and the movable link 44 drives the clamping arm 41 to rotate, so that the end of the clamping arm 41 away from the telescopic rod rotates closer to the propellant shell embedded in the arc groove. Conversely, when the piston rod of the clamping drive cylinder 46 retracts, the fixed link 45 and the movable link 44 drive the end of the clamping arm 41 away from the telescopic rod to move away from the propellant shell. Furthermore, a limiting rod 47 is fixed on the base 43. The limiting rod 47 is located on the side of the fixed connecting rod 45 away from the product support seat 42. The axis of the limiting 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 extends to drive the fixed connecting rod 45 to rotate, when the piston rod of the clamping drive cylinder 46 extends to its maximum length, the fixed connecting rod 45 and the limiting rod 47 abut against each other. At this time, the included angle formed by the axis of the movable connecting rod 44 and the axis of the fixed connecting rod 45 on the side closer to the product support seat 42 is less than 180°. At this time, when the clamping arm 41 is rotated away from the propellant shell by the force of the propellant shell, the force applied by the clamping arm 41 to the fixed connecting rod 45 through the movable connecting rod 44 acts on the limiting rod 47, rather than on the clamping drive cylinder 46, thereby protecting the clamping drive cylinder 46 and ensuring that the clamping arm 41 fixes the propellant shell and prevents the product from tipping over.

[0043] Reference Figure 3As shown, to enable the clamping arm 41 to clamp propellant casings of different diameters, the movable connecting rod 44 is designed to be telescopic. Specifically, the movable connecting rod 44 includes two coaxial connecting cylinders 441, which are connected by an adjusting screw 442. Both ends of the adjusting screw 442 are inserted into the two connecting cylinders 441, and both are threadedly connected to the screw. Thus, by rotating the adjusting screw 442, the two connecting cylinders 441 can be moved closer or further apart, allowing the movable connecting rod 44 to extend or shorten. When the fixed connecting rod 45 rotates to abut against the limiting rod 47, the distance between the end of the clamping arm 41 that contacts the propellant casing and the product support base 42 can be adjusted by regulating the length of the movable connecting rod 44. In practical applications, the length of the movable link 44 is adjusted according to the specifications of the propellant shell being flipped so that when the fixed link 45 rotates to abut against the limit rod 47, the end of the clamping arm 41 that contacts the propellant shell just forms abutment against the product support base 42, so that the propellant shell is stably pressed onto the product support base 42 by the clamping arm 41, and the propellant shell is fixed in conjunction with the product support base 42.

[0044] Reference Figure 2-3 As shown, in order to avoid damage to the surface of the propellant casing by the clamping arm 41, an arc-shaped clamping plate 48 is provided at the end of the clamping arm 41 that contacts the propellant casing. The concave surface of the clamping plate 48 is used to contact the propellant casing, and a polyurethane pad and wool felt are provided on the concave surface of the clamping plate 48.

[0045] Reference Figure 1-2 As shown, both the product support base 42 and the clamping arm 41 are designed to move in a direction perpendicular to the second support surface 221. Specifically, the product support base 42 and the support side plate 21, as well as the base 43 and the support side plate 21, are movably connected via guide rails and sliders, respectively. Multiple product support bases 42 are connected and fixed via two connecting shafts. A cylinder is installed between one of the product support bases 42 and the support side plate 21 to drive the movement of multiple product support bases 42. The positions of the clamping arm 41 and the product support base 42 can be adjusted according to the structure of the propellant casing being flipped, clamping and fixing the propellant casing at suitable positions.

[0046] Reference Figure 1-2 As shown, further, two guide seats 6 are provided on the first support surface 211 at one end near the support base plate 22. The two guide seats 6 are distributed at intervals along the first axis and are used on both sides of the propellant shell to guide and limit the propellant shell.

[0047] Reference Figure 1-2As shown, a support plate 7 is provided on the support base plate 22, located on the second support surface 221. The support plate 7 includes a third support surface parallel to the second support surface 221. The propellant shell is adapted to be placed on the support plate 7 with its axis perpendicular to the third support surface. The support plate 7 is used to fix the propellant shell. Specifically, the support plate 7 is a disc-shaped plate with its axis perpendicular to the second support surface 221. 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 restrict the radial movement of the propellant shell.

[0048] To provide sufficient space for hoisting the propellant casing onto the support plate 7, the support plate 7 can move closer to or further away from the support side plate 21 in a direction perpendicular to the first support surface 211. The support plate 7 and the support base plate 22 are connected by guide rails and sliders to allow the positioning plate to move. A cylinder or hydraulic cylinder is used to drive the movement of the support plate 7. When hoisting the propellant casing onto the support plate 7, the support plate 7 is moved to a position far from the support side plate 21 to avoid collisions between the propellant casing and the positioning side plate during hoisting. After hoisting, the support plate 7 is moved closer to the support side plate 21 until the propellant casing is embedded in the arc-shaped groove of the product support seat 42.

[0049] Reference Figure 1 and Figure 5 As shown, furthermore, the frame 1 is provided with multiple base plate support seats 8. When the second support surface 221 is in a horizontal state, the support base 22 is located above the base plate support seats 8. The base plate support seats 8 are used to support the support base 22 below the support base 22 when the tilting support structure 2 rotates to the horizontal state of the second support surface 221. Specifically, the top surface of the base plate support seat 8 is set to a horizontal plane so that the base plate support seat 8 can stably support the support base 22. When the second support surface 221 is horizontal, the base plate support seat 8 bears the weight of the support base 22 and the propellant shell on it, avoiding the tilting drive cylinder 3 from being in a working state all the time, which would affect its service life.

[0050] Reference Figure 1 and Figure 4-6As shown, a side plate support frame 9 is also provided. The side plate support frame 9 and the frame 1 are distributed at intervals in the horizontal direction perpendicular to the first axis. The side plate support frame 9 is provided with multiple side plate support seats 91. When the first support surface 211 is in a horizontal state, the support side plate 21 is located below the side plate support seat 91. The side plate support seat 91 is used to support the support side plate 21 below the support side plate 21 when the flip support structure 2 rotates to the first support surface 211 is horizontal. Similarly, the top surface of the side plate support seat 91 is set to a horizontal plane so that the side plate support seat 91 can stably support the support side plate 21. When the first support surface 211 is horizontal, the side plate support seat 91 bears the weight of the support side plate 21 and the propellant shell on it, avoiding the flip drive cylinder 3 from being in a working state all the time, which would affect its service life.

[0051] Reference Figure 1 and Figure 4 As shown, furthermore, the side plate support frame 9 is provided with multiple vibration damping devices 10. When the supporting side plate 21 is in a horizontal state, it is located above the side plate support seat 91. The vibration damping device 10 includes a vibration damping seat 101, which is elliptical and can be mounted on the side plate support frame 9. The vibration damping seat 101 can be moved until its top height is lower than the top height of the side plate support seat 91. A vibration damping spring 102 is provided between the vibration damping seat 101 and the side plate support frame 9. When the vibration damping seat 101 moves downward, it overcomes the elastic force of the vibration damping spring 102. Specifically, the vibration damping device 10 includes a sleeve 103 with a vertical axis. The vibration damping seat 101 is connected to a guide shaft that passes through the sleeve 103. The vibration damping spring 102 is sleeved outside the guide shaft and located between the vibration damping seat 101 and the sleeve 103. When the flip support structure 2 rotates to the first support surface 211 in a horizontal state, 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. The vibration damping device 10 plays a vibration damping role, avoiding rigid collision between the support side plate 21 and the side plate support plate, which would cause damage to the propellant shell.

[0052] Reference Figure 5-6 As shown, a movable support plate 11 is provided on the frame 1. The upper surface of the movable support plate 11 is horizontal. When the second support surface 221 is horizontal, the support base plate 22 is located directly above the movable support plate 11. The movable support plate 11 can be vertically raised and lowered until its upper surface is flush with the first support surface 211 in the horizontal state. Specifically, the raising and lowering of the movable support plate 11 is achieved through the cooperation of a motor and a lead screw mechanism. When the flip support structure 2 rotates to the second support surface 221 being horizontal, the movable support plate 11 rises until its upper surface is flush with the second support surface 221 in the first horizontal state. The movable support plate 11 provides a standing platform for personnel to stand on and work.

[0053] Reference Figure 1 and Figure 5-6As shown, a ladder frame 12 is further provided next to the frame 1. A work platform 13, flush with a horizontal second plane, is provided on top of the ladder frame 12. The ladder frame 12 is equipped with a ladder for personnel to climb onto the work platform 13. In practical applications, the frame 1 and the side plate support frame 9 are placed in a pit, with the first support surface 211 and the second support surface 221 both flush with the ground in a horizontal state. The pit space accommodates the frame 1, the tilting drive cylinder 3, the side plate support frame 9, and the ladder frame 12. At this time, the work platform 13 is flush with the ground, and the ladder allows personnel to enter the pit for maintenance and other work. When the tilting support structure 2 rotates to the horizontal position of the second support surface 221, the movable support plate 11 rises to be flush with the ground, which can prevent personnel from accidentally falling into the pit during subsequent operations, thus improving safety.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
