Description

Technical Field

[0001] This invention relates to the field of automatic combustion chamber tilting, and specifically to a tilting platform and its working method. Background Technology

[0002] In the explosives industry, combustion chambers are typically heavy-duty, thick-walled cylindrical structures. Due to limitations in specific workshop layouts, the installation, relocation, and maintenance of combustion chambers often rely on manual lifting, primarily using simple lifting machinery and human labor. The rotation of the combustion chamber usually involves switching it between a horizontal and vertical position to facilitate internal loading, injector installation, sensor wiring, or hoisting into place. Current technology typically involves manual overhead crane lifting, with the specific steps being manual installation of lifting lugs, lifting straps, and manual lifting and rotation. During manual rotation, violent shaking, collisions, or sudden stops can occur, and the resulting inertial forces or frictional heat may induce accidental explosions. Furthermore, in traditional rotation operations, to observe the posture and adjust the position of the wire rope, operators often need to closely follow the combustion chamber's movement, sometimes even requiring manual assistance from below or to the side of the combustion chamber. This results in high labor intensity, high safety risks, and low production efficiency. Summary of the Invention

[0005] Preferably, the tilting frame assembly further includes a second lead screw, which is connected to a plurality of the guide rail seats.

The clamp and the positioning sensing device are respectively fixedly connected to the sliders, and the positioning sensing device is symmetrically arranged about the clamp. The clamp and the positioning sensing device translate along the second guide rail through the sliders, which drives the second lead screw to move the guide rail seat, thereby causing the clamp mounting platform to translate along the first guide rail.

[0007] Preferably, the clamp installation platform is further provided with a fixing plate, a plurality of flat keys located on the fixing plate, a plurality of quick-change blocks cooperating with the flat keys, and a pin; the fixing plate is set on the mounting frame and is arranged parallel to the second guide rail; the quick-change blocks are fixed on the flat keys by pins to limit the quick-release clamp and the positioning sensing device.

[0034] like Figures 1-11 As shown, this invention proposes a tilting platform, including a frame assembly 1, a tilting frame assembly 2, a clamp mounting platform 3, clamps 4, and a positioning sensing device 5. The tilting frame assembly 2 is located above the frame assembly 1, and the clamp mounting platform 3 is mounted on the tilting frame assembly 2. The clamp mounting platform 3 is equipped with clamps 4 and positioning sensing devices 5 symmetrically arranged about the clamps 4. The positioning sensing devices 5 and clamps 4 can be manually adjusted in installation position to adapt to the clamping requirements of combustion chambers of different lengths. The frame assembly 1 includes a base frame 1-1, a sliding plate guide rail 1-2, a sliding plate 1-3, a bracket 1-4, a first lead screw 1-5, a first motor 1-6, a sliding plate bearing seat 1-7, a fixing frame 1-8, and a connecting frame 1-10; the tilting frame assembly 2 includes a tilting frame 2-1, a support seat 2-2, a fixing sleeve 2-3, a positioning sleeve 2-4, a first guide rail 2-5, a second lead screw 2-6, a second motor 2-7, a guide rail seat 2-8, a guide rail lock 2-9, a drag chain 2-10, a buffer block 2-11, and a first transmission frame. 2-12, Second transmission frame 2-13; Clamp mounting platform 3 includes mounting frame 3-1, second guide rail 3-2, flat key 3-3, pin 3-4, quick change block 3-5, slider 3-6, fixing plate 3-7; Clamp 4 includes upper clamp 4-1, lower clamp 4-2, detection sensor 4-3, quick clamp 4-4, mounting base 4-5; Positioning sensing device 5 includes mounting plate 5-1, cylinder seat 5-2, locking cylinder 5-3, pin 5-4, bushing 5-5, proximity switch 5-6, and round pin assembly 5-7.

[0035] like Figure 2 and Figure 3As shown, sliding plate guide rails 1-2 are provided on both sides of the upper surface of the base frame 1-1. A sliding plate 1-3 is provided on the sliding plate guide rails 1-2, and a sliding plate bearing seat 1-7 is provided on the sliding plate 1-3. A locking device is also provided at the lower end of the sliding plate 1-3 to mechanically lock and limit the sliding plate when it reaches its position, improving the motion positioning accuracy. A first lead screw 1-5 and a first motor 1-6 connected to the first lead screw 1-5 are provided on one side of the base frame 1-1. The sliding plate 1-3 is connected to the first lead screw 1-5 on one side via a connecting block 1-10. Dust covers are provided on the outside of the first lead screw 1-5 and the first motor 1-6 to prevent dust from entering. The dust covers also include a bellows cover 1-9. The connecting block 1-10 is connected to the bellows cover 1-9 on both sides. This device achieves high-precision, stable, and reliable linear drive of the entire tilting frame through the first lead screw 1-5 and the first motor 1-6. A fixed frame 1-8 and a bracket 1-4 are also provided on the base frame 1-1. Figure 4 and Figure 6 As shown, the lower surface of the tilting frame 2-1 is provided with a first transmission frame 2-12, a second transmission frame 2-13, and a buffer block 2-11. The first transmission frame 2-12 of the tilting frame 2-1 is connected to the sliding plate bearing seat 1-7 on the sliding plate 1-3 via a bearing, and the second transmission frame 2-13 is connected to the bracket 1-4 via a bearing, forming a stable moving guide rod tilting mechanism. Figure 8 and Figure 9 As shown, when the tilting frame 2-1 is in a vertical state, the combustion chamber can be hoisted; when the tilting frame 2-1 is in a horizontal state, the combustion chamber can be stably placed and subsequent translation operations can be performed.

[0036] The buffer block 2-11 on the tilting frame 2-1 contacts the fixed frame 1-8. The cooperation between the fixed frame 1-8 and the buffer block 2-11 achieves stable support and shock absorption of the tilting frame 2-1 in the horizontal direction, reducing operational impact and noise. The first motor 1-6 drives the first lead screw 1-5 to rotate, thereby driving the sliding plate 1-3 to slide along the sliding plate guide rail 1-2. The sliding plate bearing seat 1-7 moves synchronously with the sliding plate 1-3, causing the swing center of the tilting frame 2-1 to move accordingly. Under the hinge constraint of the bracket 1-4 and the second transmission frame 2-13, the tilting frame 2-1 can smoothly switch between the horizontal and vertical states. When the first motor 1-6 drives the first lead screw 1-5 to move the sliding plate 1-3 along the sliding plate guide rail 1-2 toward the support 1-4, the flipping frame 2-1 switches to a vertical state. When the first motor 1-6 drives the first lead screw 1-5 to move the sliding plate 1-3 along the sliding plate guide rail 1-2 toward the support 1-4, the flipping frame 2-1 is in a horizontal state.

[0037] A support seat 2-2 is provided at one end of the upper surface of the flipping frame 2-1. The support seat 2-2 is located above the first transmission frame 2-12. The support seat 2-2 is provided with a fixing sleeve 2-3 and a positioning sleeve 2-4 located inside the fixing sleeve 2-3. The support seat 2-2 provides axial coarse positioning for the combustion chamber and is used for bottom support of the product to prevent the combustion chamber from falling during the flipping process, thereby improving safety. The upper surface of the tilting frame is provided with a first guide rail 2-5 on both sides, several guide rail seats 2-8 and guide rail locks 2-9 located on the first guide rail 2-5. The guide rail seats 2-8 are connected to the second lead screw 2-6, and the second lead screw 2-6 is connected to the second motor 2-7. A mounting bracket 3-1 is fixed on the guide rail seat 2-8. The guide rail locks 2-9 are arranged between the guide rail seats 2-8. The guide rail locks 2-9 are pneumatic. The second motor 2-7 drives the second lead screw 2-6 to rotate, thereby driving the guide rail seat 2-8 to move along the first guide rail 2-5. The mounting bracket 3-1 moves with the guide rail seat 2-8 and translates. When the guide rail seat 2-8 moves, the guide rail locks 2-9 move accordingly. When the guide rail seat 2-8 is in place, the guide rail locks 2-9 are pneumatically locked, thereby rigidly limiting the guide rail seat 2-8 to ensure no swaying or displacement under heavy load.

[0038] like Figure 5 As shown, the mounting frame 3-1 has second guide rails 3-2 on both sides and several sliders 3-6 on the second guide rails 3-2. The clamp 4 is fixed to the sliders 3-6 by the mounting base 4-5. The positioning sensing device 5 is fixed to the sliders 3-6 by the mounting plate 5-1. The mounting frame 3-1 also has a fixing plate 3-7, which is located between the two second guide rails 3-2 and is parallel to the second guide rails 3-2. The fixing plate 3-7 has several flat keys 3-3. The quick-change block 3-5 is fixed to the flat key 3-3 by the pin 3-4. The clamp 4 and the positioning sensing device 5 can be manually changed along the second guide rails 3-2 by the sliders 3-6. After the quick-change block 3-5 is manually adjusted, it limits the clamp 4 and the positioning sensing device 5 to ensure clamping accuracy and consistent repeatability.

[0039] like Figure 7 As shown, a lower clamp 4-2 is fixed on the mounting base 4-5 of the clamp 4, and an upper clamp 4-1 is connected to the lower clamp 4-2. The upper clamp 4-1 and the lower clamp 4-2 are clamped and fixed by quick clamps 4-4 to prevent the clamps from coming loose. Detection sensors 4-3 are respectively provided on both sides of the mounting base 4-5. The detection sensor 4-3 on the quick clamp 4-4 side is used to detect when the clamp is in place to prevent it from being loose, while the detection sensor 4-3 on the other side is used for in-place detection to prevent the clamp from not opening when the robotic arm grasps it. The inner sides of the upper clamp 4-1 and the lower clamp 4-2 are coated with rubber to prevent wear on the combustion chamber surface. The clamp 4 is used for quick fixing of products with a combustion chamber length > 1800mm to prevent the combustion chamber from tipping over during rotation.

[0040] like Figure 8As shown, the mounting plate 5-1 of the positioning sensing device 5 has cylinder seats 5-2 on both sides and locking cylinders 5-3 fixed on the cylinder seats 5-2. The locking cylinders 5-3 are connected to the pins 5-4. A bushing 5-5 is also provided on the outside of the pins 5-4. The cylinder seats 5-2 are fixed to the mounting plate 5-1 by a round pin assembly 5-7. The cylinder seats 5-2 are also provided with a proximity switch 5-6 to detect the extension and retraction status of the pins 5-4, realizing closed-loop monitoring and safety interlocking of the locking action. After the positioning sensing device 5 is positioned and fixed, the locking cylinder drives the pins 5-4 to extend and engage with the fastening clamp on the combustion chamber.

[0041] like Figure 11 As shown, the specific working method of the tilting platform includes tilting the tilting frame 2-1 to a vertical state before loading to facilitate the hoisting and loading of the combustion chamber. After the clamp 4 is opened, the combustion chamber is clamped and fixed. The positioning sensor 5 is adjusted and fixed to the limit position of the combustion chamber. Then, the tilting frame 2-1 is tilted to a horizontal state. Subsequently, the clamp mounting platform 3 and the combustion chamber are moved horizontally to the gripping position. Then, the combustion chamber is gripped and moved away by the robot and reset. After the combustion chamber is hoisted and unloaded, it is moved away. Finally, the clamp mounting platform 3 is adjusted to move horizontally back to the initial position, and the tilting frame 2-1 is reset to a vertical state. The above steps are repeated to achieve continuous operation.

[0042] Before loading, the first motor 1-6 drives the first lead screw 1-5 to move the sliding plate 1-3 along the sliding plate guide rail 1-2 until the tilting frame 2-1 is in a vertical state; the combustion chamber is hoisted, the clamp 4 is opened to clamp and fix the combustion chamber, and the positioning sensor 5 is adjusted and automatically sensed to engage and fix the fastening clamp on the combustion chamber; then the first motor 1-6 drives the first lead screw 1-5 to move the sliding plate 1-3 along the sliding plate guide rail 1-2 until the tilting frame 2-1 reaches a horizontal state; the second motor 2-7 drives the second lead screw 2-6 to rotate, thereby driving the guide rail seat 2-8 to move along the first guide rail 2-5, and the clamp mounting platform 3 moves away from the support seat 2-2 until the combustion chamber is horizontally moved to the gripping position, at which point the combustion chamber... One end does not contact the fixing sleeve 2-3 and positioning sleeve 2-4 inside the support base 2-2, which facilitates the subsequent hoisting of the combustion chamber; the combustion chamber is grasped by a robot arm; after the upper clamp 4-1 of the clamp 4 is opened by the quick clamp 4-4, the combustion chamber is moved to the automatic demolding device by the robot arm for subsequent operations. After completion, the combustion chamber is moved back to the clamp mounting platform 3 by the robot arm. The automatic demolding device, robot arm, combustion chamber and tilting platform are in the same high-temperature working environment. After the combustion chamber cools down, the combustion chamber is hoisted and unloaded; the second motor 2-7 drives the second lead screw 2-6 to rotate, thereby driving the guide rail seat 2-8 to move along the first guide rail 2-5 until the clamp mounting platform 3 returns to the initial position. The above steps are repeated to achieve continuous operation.
