Description

Technical Field

[0001] This invention belongs to the field of cylinder loading equipment, and specifically relates to an automatic horizontal cylinder loading device. Background Technology

[0002] When loading projectiles, the cylinder needs to be pushed horizontally. Traditionally, loading is done manually or by hoisting. However, due to the large structure and weight of the cylinder, it's difficult to ensure its level using these methods, affecting the loading efficiency. Furthermore, the external converter and tail-end deployment mechanism need to be clamped and folded during loading, also manually, placing significant physical demands on the loading personnel. Prolonged work can lead to fatigue and significantly extend loading time. Manual loading also introduces many uncertainties, such as low loading accuracy and difficulty in ensuring the projectile is properly positioned. Therefore, automatic cylinder loading technology is a novel technology suitable for future unmanned intelligent manufacturing. Unlike traditional loading methods, automatic cylinder loading devices can achieve rapid, fully automated loading. This invention focuses on the research of an automatic cylinder loading device. Summary of the Invention

[0003] To address the above problems, this invention provides an automatic horizontal loading device for cylinders, which combines control technologies of a cylinder pushing mechanism and a cylinder supporting mechanism, automatic reset technology, and flexible adaptive alignment technology to achieve rapid and fully automatic loading of cylinders.

[0004] An automatic horizontal loading device for a cylinder includes a cylinder pusher, a converter clamping device, and a cylinder support. The cylinder pusher and cylinder support support carry and push the cylinder to move, while the converter clamping device clamps the converter on the cylinder and folds the tail-end unfolding mechanism.

[0005] The pusher assembly consists of a main frame and a pusher tailstock. A first guide rail is located at the bottom of the main frame, and sprocket drive mechanisms providing power for movement are located on both sides of the main frame. These sprocket drive mechanisms consist of multiple sprockets and a chain; rotation of the sprockets drives the chain to rotate. A sprocket drive mechanism is located at one end of the main frame, and is powered by the sprockets at the end. The sprocket drive mechanism drives the sprockets to rotate, thus providing power for the movement of the cylinder. The pusher tailstock is slidably connected to the first guide rail, and a chain buckle is located on each side of the pusher tailstock. The chain buckles are connected to the chain, and when the chain rotates, the chain buckles drive the pusher tailstock to move along the first guide rail. A connector is also provided on the pusher tailstock, allowing the tail of the cylinder to be connected to it.

[0006] The cylinder support is slidably mounted on the first guide rail. The upper end of the cylinder support is provided with a support frame that can fix the cylinder. By fixing the cylinder on the cylinder support, the cylinder support moves on the first guide rail, which in turn drives the cylinder to move.

[0007] Two converter clamping devices are used, movably mounting the converter on both sides of the main frame. These devices clamp and fold the converter and tail-end unfolding mechanism on the cylinder from both sides of the main frame. Each converter clamping device includes a movable base, a control device, a clamping mechanism, a folding mechanism, and a pre-compression mechanism. The control device controls the operation of the clamping, folding, and pre-compression mechanisms. The clamping and folding mechanisms are mounted on the same side above the movable base to allow operation of the cylinder. The control device is mounted on the other side above the movable base, and the pre-compression mechanism is integrated into the control system.

[0008] To clamp the converter on the cylinder, the clamping mechanism consists of a first base, clamps, a first cylinder, and connecting rods. There are two clamps and two connecting rods, which are symmetrically hinged to the first base. The first cylinder is fixed to the first base. One end of each connecting rod is hinged to the end of the first cylinder, and the other end is hinged to the middle of the two clamps respectively. When the first cylinder extends or retracts, the connecting rods can drive the clamps to open or close, thus achieving the clamping function. The clamping mechanism is mounted on a movable base via the first base.

[0009] To achieve the folding of the tail unfolding mechanism on the cylinder, the folding mechanism consists of a folding wheel, a second base, and a second cylinder. The folding wheel is installed at the end of the second cylinder. There are two second cylinders, which are installed in parallel on the second base. The folding wheel is moved by the extension and retraction of the two second cylinders to achieve the folding function. The folding mechanism is installed on the movable base through the second base.

[0010] To achieve the automatic pusher function, the sprocket drive mechanism consists of a drive motor and a reducer. The drive motor is connected to one end of the reducer, and the other end of the reducer is connected to the sprocket, allowing the drive motor to drive the sprocket to rotate through the reducer.

[0011] To adapt to different operating conditions of the pusher cylinder: the connector is connected to the tailstock of the pusher cylinder via a screw jack, allowing the connector to move up and down to adjust its position connected to the cylinder body.

[0012] Meanwhile, the cylinder support consists of a bottom plate and a top plate. The bottom plate is slidably connected to a first guide rail. A slide rail is installed between the top and bottom plates, connecting the top plate to the bottom plate. The slide rail is perpendicular to the first guide rail, and the cylinder frame is connected to the top plate via a lifting cylinder. The spatial position of the cylinder frame can be adjusted using the slide rail and the first guide rail to adapt to different cylinder pushing conditions.

[0013] A second guide rail is installed on the movable base, and two third guide rails are slidably connected to the second guide rail. The third guide rails are kept perpendicular to the second guide rail, allowing the first and second bases to be slidably connected to the two third guide rails respectively, thus enabling adjustment of their positions on the horizontal plane. To achieve automatic adjustment of the first and second bases, a third cylinder is connected to each end of the second guide rail, and a fourth cylinder is vertically connected to the end of each of the two third cylinders. The ends of the two fourth cylinders are connected to the first and second bases respectively. By controlling the third and fourth cylinders, the positions of the first and second bases can be adjusted.

[0014] To achieve the pre-compression function of the converter, the pre-compression mechanism consists of a fifth cylinder, a fixed plate, limiters, and a fixed base. The fixed base is fixed to the upper end of the control system, and two limiters are located on both sides of the fixed base. The fixed base and limiters are used to fix the position of the converter. The fixed plate is vertically set on the side of the fixed base, and the fifth cylinder is fixed on the fixed plate, positioning the fifth cylinder above the fixed base. After the fifth cylinder is activated, the converter is pre-compressed.

[0015] To prevent the pusher tailstock from being unable to be adjusted when the drive motor fails, a manual handle is connected to the sprocket drive mechanism. The manual handle is connected to the reducer, and the manual handle and the drive motor are located at the same end of the reducer. When the drive motor fails, the manual handle can be rotated to rotate the sprocket, thereby adjusting the position of the pusher tailstock.

[0016] In order to move the position and horizontal height of the main frame and the converter clamping device, casters and lifting supports are installed at the bottom of the main frame and the mobile base. The casters allow for movement, and when a fixed position is needed, the height of the lifting supports can be adjusted to lift the main frame and the converter clamping device, so that the casters leave the ground and the position of the main frame and the converter clamping device is fixed.

[0017] To further improve the efficiency of the pusher tailstock's position movement when the drive motor is not working, a crossbar is also provided on the pusher tailstock. The pusher tailstock can be moved by pulling the steel cable through the crossbar.

[0018] The automatic horizontal loading device for cylinders provided by this invention can achieve rapid and fully automatic loading of cylinders, ensuring that the cylinders are completely horizontal during the loading process. It can simultaneously process the converter and the tail unfolding mechanism, ensuring that the cylinders are loaded in one go, avoiding the problems of low efficiency and low accuracy of manual loading. It can load different types of cylinders, has a wide range of applications, and a high degree of automation. Attached Figure Description

Detailed Implementation

[0021] To further illustrate the concept of this invention, specific embodiments will be provided below for detailed explanation. These embodiments are merely illustrative and explanatory and should not be construed as limiting the scope of protection of this invention. All technologies implemented based on the content of this invention are covered within the scope of protection intended by this invention.

[0022] A horizontal automatic loading device for cylinders, such as Figure 1As shown, it consists of a pusher device 1, a converter clamping device 2, and a cylinder support 3, which decomposes the spatial motion coordinates into three directions: the horizontal x and y directions and the vertical z direction.

[0023] The pusher device 1 consists of a main frame 11 and a pusher tailstock 12. A first guide rail 111 in the x-direction is provided at the bottom of the main frame 11. Multiple parallel sprockets are provided on both sides of the main frame 11, and a chain is fitted onto each sprocket to form a sprocket drive mechanism 112. A sprocket drive mechanism 113 is provided at the left end of the main frame 11. The top of the sprocket drive mechanism 113 contains a drive motor 114 and a manual handle 116. The drive motor 114 and the manual handle 116 are connected to the power input end of a reducer 115, and the power output end of the reducer 115 is connected to the leftmost sprocket. Figure 3 As shown. Multiple casters and lifting supports are installed at the bottom of the main frame 11; the number is determined by the length of the main frame 11, as shown. Figure 2 As shown.

[0024] The bottom of the pusher tailstock 12 is slidably mounted on the first guide rail 111. Chain buckles 121 are installed on both sides of the pusher tailstock 12, and the two chain buckles 121 are respectively fastened to the chains on both sides. A lead screw jack is installed on the top of the pusher tailstock 12, and a connector 122 is connected to the lead screw jack. Two crossbars 124 are installed on each side of the support tailstock, as shown below. Figure 4 As shown.

[0025] The cylinder support 3 consists of a base plate 32, a top plate 33, and a cylinder support frame 31. The base plate 32 is slidably mounted on the first guide rail 111. A slide rail 34 is fixed to the upper end of the base plate 32, and the top plate 33 is slidably connected to the slide rail 34. The slide rail 34 is arranged along the y-direction. A lifting cylinder 35 is installed in the middle of the upper end of the top plate 33, and a clamp is fixed to the top of the lifting cylinder 35 as the cylinder support 3. Figure 5 As shown.

[0026] The bottom of the movable base 21 of the converter clamping device 2 is equipped with four movable wheels and four lifting support feet. A second guide rail 211 is set at one end of the movable base 21, and two third guide rails 212 are installed on the second guide rail 211, allowing the third guide rails 212 to slide along the second guide rail 211. The second guide rail 211 is set along the x-direction, and the third guide rails 212 are set along the y-direction. The control device 22 is installed at the other end of the movable base 21. A fixed base 254 is installed on the upper surface of the control device 22. Two limiters 253 are symmetrically installed on both sides of the fixed base 254. The fixed plate 252 is vertically fixed to the side of the fixed base 254. Then, the fifth cylinder 251 is fixed to the fixed plate 252, so that the fifth cylinder 251 is located above the fixed base 254 and vertically downward, forming a pre-compression mechanism 25. Figure 9As shown. The clamping mechanism 23 consists of a first base 231, clamps 232, a first cylinder 233, and connecting rods 234. The two clamps 232 are symmetrically hinged to the first base 231. The first cylinder 233 is mounted on the first base 231 with its top end positioned between the two clamps 232. One end of each connecting rod 234 is hinged to the top end of the first cylinder 233, and the other ends are hinged to the middle portions of the two clamps 232. The first base 231 is slidably mounted on a third guide rail 212. Figure 7 As shown. The folding mechanism 24 consists of folding wheels 241, a second base 242, and a second cylinder 243. Two rubber folding wheels 241 are respectively mounted on the ends of the two second cylinders 243. The two second cylinders 243 are then mounted parallel to each other on the second base 242. The second base 242 is slidably connected to another third guide rail 212, as shown. Figure 8 As shown. A third cylinder 213 in the y-direction is connected to each end of the second guide rail 211. A fourth cylinder 214 in the x-direction is connected to the ends of the two third cylinders 213. The ends of the two fourth cylinders 214 are connected to the first base 231 and the second base 242, respectively. Figure 6 As shown.

[0027] When loading the cylinder horizontally, the cylinder pusher 1 is moved to the working position via the moving wheels at the bottom of the main frame 11. Then, the lifting support feet are lowered to fix the position of the cylinder pusher 1, completing the fixation of the entire device. Two cylinder supports 3 are installed on the main frame 11, with a distance between the two cylinder supports 3, and the cylinder is fixed on the cylinder support frame 31. The position of the cylinder support frame 31 is adjusted by the lifting cylinder 35 and the slide rail 34 to keep the cylinder coaxial with the installation position. Then, the sprocket is controlled to rotate by the drive motor 114, so that the chain drives the cylinder pusher tail seat 12 to move to the tail end of the cylinder. The connector 122 is moved to a fixed position by the screw jack, and the connector 122 is connected to the cylinder.

[0028] Move the two symmetrical converter clamping devices 2 to both sides of the main frame 11, positioning them in the designated positions. Secure the converter clamping devices 2 with lifting supports, and adjust the height of the lifting supports so that the clamping mechanism 23 and the folding mechanism 24 are aligned with the cylinder in the z-direction. First, place the converter on the fixed plate 252, limiting its position with the limiter 253. Activate the fifth cylinder 251 to pre-compress the converter. After pre-compression, remove the converter and install it on the cylinder. Install all converters in the same manner. Then, control the movement of the clamping mechanism 23 using the control device 22. Use the third guide rail 212 and the second guide rail 211 to control the movement of the clamping mechanism 23 in the x and y directions, allowing the clamp 232 to loosely clamp the converter on the cylinder. Then, activate the first cylinder 233 to control the clamp 232 to firmly clamp the converter. Then, using the same method, the folding mechanism 24 is moved to the corresponding position of the tail unfolding mechanism on the cylinder. Then, the second cylinder 243 is activated to move the folding wheel 241 toward the tail unfolding mechanism. As the folding wheel 241 contacts the tail unfolding mechanism, it folds the tail unfolding mechanism. The folding and fixing of the cylinder is completed in the above manner.

[0029] Then, the support frame 31 is removed from the cylinder body, separating the cylinder support 3 from the cylinder body to prevent the cylinder support 3 from affecting the loading operation. Then, the drive motor 114 is started, causing the pusher tail seat 12 to move in the loading direction, pushing the cylinder to perform the loading operation. During loading, the clamping mechanism 23 and the folding mechanism 24 move synchronously until the cylinder is fully loaded. If a power outage or damage to the drive motor 114 occurs during the installation process, the manual handle 116 can be manually rotated to control the movement of the pusher tail seat 12. A steel cable is connected to the crossbar 124 on the pusher tail seat 12, and the pusher tail seat 12 is pulled by the steel cable.

[0030] The entire power supply of the device uses an isolation transformer for power protection to prevent leakage current from the electrical cabinet and components from being conducted to the equipment in use. The safety circuit employs a dual protection method, using both the main power supply and control power supply to disconnect the circuit. Combined with the design of the isolation transformer and safety circuit, the entire system control of the device can be used safely and reliably. Figure 10 As shown.
