Description

Technical Field

[0001] This utility model relates to the field of gas cylinder device technology, specifically to a device for pouring sand particles inside a gas cylinder. Background Technology

[0002] In industrial production, gas cylinders, as mobile pressure vessels for storing and transporting various gases, are crucial for safety and the purity of the medium. Especially for cylinders containing permanent gases or liquefied gases, sand, rust debris, and other impurities can easily accumulate on their inner walls after prolonged use. Failure to clean them promptly can lead to valve blockage, medium contamination, and even container wall abrasion. Therefore, the efficient emptying and cleaning of sand particles from inside gas cylinders has become a critical process in the industry. Currently, the emptying of sand particles from gas cylinders mostly relies on manual turning or simple mechanical assistance, which has significant drawbacks: manual operation is not only labor-intensive, but the gas cylinder is also prone to shaking during the turning process, causing impurities to splash, and it is difficult to accurately control the turning angle, resulting in sand particles remaining; existing mechanical devices have problems such as complex structure and poor adaptability.

[0003] For example, Chinese utility model patent CN222957142U discloses a flipping device for seamless gas cylinder processing, which uses a servo motor to drive a rotating rod to achieve synchronous flipping of multiple gas cylinders, thus improving batch processing efficiency. However, the rod-type transmission structure used makes it difficult to achieve precise 180-degree positioning of a single cylinder, and it lacks a dedicated unloading guide structure, allowing sand particles to easily scatter into the gaps between the equipment and cause contamination. In addition, the clamping mechanism of this device uses a combination of clamping plates and handwheels, which requires repeated adjustments for gas cylinders of different diameters, resulting in limited adaptability and failing to meet the high requirements for clamping stability when sand particles are being dumped. Utility Model Content

[0004] The purpose of this utility model is to provide a device for tilting sand particles inside a gas cylinder, so as to solve the problem that tilting sand particles in gas cylinders, as mentioned in the background art, mostly relies on manual turning or simple mechanical assistance, which has significant drawbacks: manual operation is not only labor-intensive, but the gas cylinder is also prone to shaking during the turning process, causing impurities to splash. At the same time, it is difficult to accurately control the tilting angle, resulting in the problem of sand particles remaining.

[0005] To achieve the above objectives, this utility model provides a gas cylinder sand-pouring device, including a base, a guide component mounted on the top of the base, and a clamping component provided on one side of the guide component for clamping and fixing the gas cylinder. The guide component includes a track ring, and a guide toothed ring is mounted on the inner side of the track ring. The clamping component includes a support cylinder, and a drive motor is mounted on the outer wall of one bottom side of the support cylinder. A drive gear is mounted on the output shaft of the drive motor, and the drive gear meshes with the guide toothed ring.

[0006] This setup uses a base to support the guide and clamping components, with a guide gear ring (fixed to the track ring) and a drive gear (connected to a servo motor) forming a meshing transmission pair. When the drive motor operates, the circumferential force generated by the gear meshing drives the support cylinder to rotate around the track ring, achieving the tilting action of the gas cylinder. The track ring provides a fixed trajectory for the gear transmission, ensuring the stability of the tilting path.

[0007] Preferably, a discharge trough is provided on the top surface of the base near the gas cylinder, and the inner wall of the discharge trough is a downwardly concave arc surface structure.

[0008] This design incorporates a downward-recessed, curved surface structure in the unloading chute. Utilizing gravity and the guiding properties of the curved surface, the poured sand particles naturally slide down the curved surface to the lower part of the chute. The curvature of the curved surface has been optimized to accommodate material flow trajectories at different pouring speeds.

[0009] Preferably, both outer walls of the support cylinder are fitted with tightening bolts, the gas cylinder is placed inside the support cylinder, and the threaded end of the tightening bolt passes through the side wall of the support cylinder and can abut against the outer wall of the gas cylinder.

[0010] This design uses tightening bolts on both sides of the support cylinder to generate radial pressure, which in turn uses friction to secure the outer walls of the gas cylinder. The symmetrical distribution of the two tightening bolts ensures balanced clamping force, preventing the gas cylinder from shifting under stress, and the tightening depth of the two bolts can be adjusted to accommodate gas cylinders of different diameters.

[0011] Preferably, positioning frames are provided on both sides of the support cylinder, the bottom end of the positioning frame is fixed on the base, and the top end of the positioning frame is rotatably connected to the top side of the support cylinder through a bearing.

[0012] This feature connects the positioning frame to the support cylinder via a bearing, converting the sliding friction of the support cylinder into rolling friction within the bearing. This significantly reduces rotational resistance, while the bearing can withstand radial loads, ensuring the axial stability of the support cylinder during rotation.

[0013] Preferably, a bracket is installed on one outer wall of the track ring, and the bottom of the bracket is fixed to the base.

[0014] This bracket design rigidly fixes the track ring to the base, forming a stable triangular support structure that can counteract the reaction force generated during gear meshing and prevent the track ring from shifting during transmission.

[0015] Preferably, the inner diameter of the support cylinder is larger than the diameter of the gas cylinder.

[0016] This setting provides a support cylinder with an inner diameter larger than the gas cylinder's diameter, and the reserved gap provides operating space for inserting, removing, and fine-tuning the angle of the gas cylinder, while also being compatible with gas cylinders of different diameters (within a certain range).

[0017] Preferably, the bottom of the base is equipped with an anti-slip pad.

[0018] This anti-slip pad increases the coefficient of friction between the base and the ground, using static friction to counteract the horizontal reaction force generated when the equipment flips, thus preventing the entire device from sliding.

[0019] Preferably, the drive motor is a servo motor, which drives the drive gear to rotate, thereby achieving a 180-degree rotation adjustment of the gas cylinder to pour out the internal sand particles.

[0020] This setting features a servo motor with closed-loop control characteristics, which can accurately respond to control signals. Through the meshing transmission of the drive gear and the guide gear ring, the angular displacement of the motor is converted into the rotation angle of the gas cylinder, achieving 180-degree precise positioning.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: The gas cylinder sand-tipping device employs a drive motor (servo motor) and a meshing transmission structure between a guide gear ring and a drive gear. Combined with the guiding action of the track ring, it enables precise 180-degree tilting adjustment of the gas cylinder. Compared to the rod-type transmission in the comparative document, which suffers from difficulty in precise positioning, this structure can strictly control the tilting angle, ensuring that the sand inside the gas cylinder is completely tilted out under gravity. This effectively solves the problem of sand residue caused by angular deviations in traditional manual operation or simple machinery. The combination of the support cylinder and the tightening bolt in the clamping component allows for adaptation to gas cylinders of different diameters by adjusting the tightening force of the bolt. Compared to the complex adjustment method of the clamping plate and handwheel in the comparison document, this method is more convenient to operate and significantly improves clamping stability. Furthermore, the inner diameter of the support cylinder is larger than the diameter of the gas cylinder, providing buffer space for the cylinder and preventing cylinder swaying during inversion through the tightening bolt. This fundamentally solves the risk of impurities splashing and cylinder falling, complying with safety regulations for pressure vessel operation. The curved discharge chute on the base precisely catches spilled sand when the gas cylinder is tilted, preventing it from scattering into equipment gaps or the work area. Compared to the design in the prior art, which lacks a dedicated discharge guide, this structure reduces sand wear on the equipment and environmental pollution, and lowers subsequent cleaning workload.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a device for tilting sand particles inside a gas cylinder, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the device includes a base 1, a guide component 2 mounted on the top of the base 1, and a clamping component 3 on one side of the guide component 2. The clamping component 3 is used to clamp and fix the gas cylinder 4. The guide component 2 includes a track ring 21, and a guide toothed ring 22 is mounted on the inner side of the track ring 21. The clamping component 3 includes a support cylinder 32, and a drive motor 35 is mounted on the outer wall of one bottom side of the support cylinder 32. A drive gear 351 is mounted on the output shaft of the drive motor 35, and the drive gear 351 meshes with the guide toothed ring 22.

[0025] In use, the base 1 supports the guide component 2 and the clamping component 3. The guide gear ring 22 on the inner side of the track ring 21 and the drive gear 351 on the output shaft of the drive motor 35 form a meshing transmission pair. When the drive motor 35 runs, the circumferential force generated by the gear meshing drives the support cylinder 32 to rotate around the track ring 21, realizing the flipping action of the gas cylinder 4. The track ring 21 provides a fixed trajectory for the gear transmission, ensuring the stability of the flipping path. Results: Compared to the lever drive in comparison document CN222957142U, the gear meshing drive offers higher precision and a constant transmission ratio, enabling precise control of the gas cylinder's four tilt angles, laying the foundation for a subsequent complete 180-degree tilt. Simultaneously, the modular component layout makes the overall structure compact, resolving the sand residue problem caused by angular deviations in traditional devices.

[0026] In this embodiment, as Figure 1 , Figure 2As shown, a discharge trough 11 is provided on the top surface of the base 1 near the gas cylinder 4, and the inner wall of the discharge trough 11 is a downwardly concave arc surface structure.

[0027] In use, the downward-concave arc-shaped structure of the unloading chute 11 utilizes gravity and the flow-guiding properties of the curved surface to allow the poured sand particles to naturally slide down the arc surface and flow to the lower part of the chute. The curvature of the arc surface has been optimized to adapt to the material flow trajectory at different pouring speeds. Compared to existing technologies that lack a dedicated unloading structure, this arc-shaped groove improves sand collection efficiency, reduces material spillage and wear on equipment and environmental pollution, and also reduces subsequent cleaning workload. Similar to the curved liner principle of dump trucks in mining areas, it achieves efficient unloading.

[0028] Specifically, such as Figure 4 As shown, tightening bolts 34 are installed on both outer walls of the support cylinder 32. The gas cylinder 4 is placed inside the support cylinder 32. The threaded end of the tightening bolt 34 passes through the side wall of the support cylinder 32 and can abut against the outer wall of the gas cylinder 4.

[0029] In use, the tightening bolts 34 on both sides of the support cylinder 32 generate radial pressure by tightening, and use friction to fix the outer walls of the gas cylinder 4. The symmetrical distribution of the two tightening bolts 34 ensures balanced clamping force, preventing the gas cylinder 4 from shifting under force, and the tightening depth of the bolts 34 can be adjusted to accommodate gas cylinders 4 of different diameters. Compared with the clamping plate and handwheel combination of the comparison document, this structure is more convenient to operate, achieves stable clamping without complex calibration, has higher precision in clamping force adjustment, and effectively prevents impurities from splashing due to the shaking of the gas cylinder 4 during the flipping process, complying with the safety regulations for pressure vessel operation.

[0030] Furthermore, such as Figure 4 As shown, positioning frames 31 are provided on both sides of the support cylinder 32. The bottom end of the positioning frame 31 is fixed on the base 1, and the top of the two positioning frames 31 is rotatably connected to the top side of the support cylinder 32 through bearings 33.

[0031] In use, the positioning frame 31 is connected to the support cylinder 32 via the bearing 33, converting the sliding friction of the support cylinder 32 into rolling friction within the bearing 33, significantly reducing rotational resistance. Simultaneously, the bearing 33 can withstand radial loads, ensuring the axial stability of the support cylinder 32 during tilting. This structural design reduces transmission losses, making the tilting action smoother. Compared to a rigid connection, the bearing 33 structure can buffer vibrations during tilting, extending the equipment's service life, while also ensuring the consistency of the gas cylinder 4's tilting trajectory.

[0032] Furthermore, such as Figure 3 As shown, a bracket 23 is installed on one outer wall of the track ring 21, and the bottom of the bracket 23 is fixed on the base 1. The track ring 21 and one of the positioning frames 31 are in the same plane.

[0033] In use, the bracket 23 rigidly fixes the track ring 21 to the base 1, forming a stable triangular support structure that can counteract the reaction force generated during gear meshing and prevent the track ring 21 from shifting during transmission. This structural design improves the overall stability of the guide component 2, avoids affecting the gear meshing accuracy due to the wobbling of the track ring 21, ensures the reliability of the flip angle control, and solves the positioning deviation problem caused by unstable support in traditional devices.

[0034] Furthermore, the inner diameter of the support cylinder 32 is larger than the diameter of the gas cylinder 4.

[0035] In use, the inner diameter of the support cylinder 32 is larger than the diameter of the gas cylinder 4. The reserved gap provides operating space for the insertion, removal, and fine-tuning of the gas cylinder 4, while also being compatible with gas cylinders 4 of different diameters within a certain range. This structural design enhances the adaptability of the device, allowing it to handle various specifications of gas cylinders 4 without replacing the clamping component 3, making it particularly suitable for scenarios involving the mixed handling of multiple types of gas cylinders 4.

[0036] Furthermore, such as Figure 1 , Figure 2 As shown, an anti-slip pad 12 is installed on the bottom of the base 1.

[0037] In use, the anti-slip pad 12 increases the coefficient of friction between the base 1 and the ground, using static friction to counteract the horizontal reaction force generated when the equipment is turned over, thus preventing the entire device from sliding. This structural design improves the stability of the equipment during operation, avoids deviations in the tilting angle of the gas cylinder 4 caused by the slippage of the base 1, and is especially suitable for smooth surfaces or high-intensity working environments, ensuring that operational safety meets industrial equipment standards.

[0038] Furthermore, the drive motor 35 is a servo motor. The drive motor 35 drives the drive gear 351 to rotate, thereby achieving a 4180-degree rotation adjustment of the gas cylinder and emptying the internal sand particles.

[0039] In operation, the drive motor 35 is a servo motor with closed-loop control characteristics, which can accurately respond to control signals. Through the meshing transmission between the drive gear 351 and the guide gear ring 22, the angular displacement of the motor is converted into the rotation angle of the gas cylinder 4, realizing the 180-degree rotation adjustment of the gas cylinder 4 for emptying the internal sand particles. Compared with ordinary motors, this structural design of the servo motor has higher angle control precision, ensuring that the gas cylinder 4 reaches the preset angle every time it is rotated, solving the angle error problem of traditional manual rotation or simple machinery.

[0040] When the gas cylinder sand-pouring device of this utility model is in use, the drive motor 35 first drives the drive gear 351 to rotate. The drive gear 351 meshes with the guide gear ring 22 on the inner side of the track ring 21 to convert the power of the motor into the circumferential motion of the clamping component 3, thereby achieving the precise flipping of the gas cylinder 4. The support cylinder 32, together with the tightening bolts 34 on both sides, fixes the gas cylinder 4 with radial pressure. The combination of the positioning frame 31 and the bearing 33 ensures the stability of the axis of the support cylinder 32 during the flipping process, preventing the gas cylinder 4 from shaking. The track ring 21 provides a fixed trajectory for flipping, and the unloading trough 11 on the base 1 collects the poured sand particles through the arc-shaped flow guiding characteristics, realizing the integrated operation of "flipping-unloading-collection". Work process With the open end of the gas cylinder 4 to be cleaned facing upwards, place it inside the support cylinder 32. Since the inner diameter of the support cylinder 32 is larger than the diameter of the gas cylinder 4, it can be easily inserted. Tighten the clamping bolts 34 on both sides of the support cylinder 32, ensuring the bolt ends press firmly against the outer wall of the gas cylinder 4. The symmetrically distributed clamping force ensures the gas cylinder 4 is securely positioned, preventing displacement during flipping. Then, start the drive motor 35. The output shaft of the servo motor drives the drive gear 351 to rotate. Through engagement with the guide gear ring 22, it drives the clamping component 3 to slowly rotate around the track ring 21. During the flipping process, the positioning frame 31 is connected to the support cylinder 32 via the bearing 33, converting sliding friction into rolling friction and reducing resistance. Simultaneously, the bracket 23 fixes the track ring 21, preventing wobbling during transmission.

[0041] The drive motor 35 achieves precise speed regulation through closed-loop control, driving the gas cylinder 4 to gradually rotate to 180 degrees. At this point, the open end of the gas cylinder 4 faces downwards, and the sand particles inside are poured into the unloading trough 11 under the action of gravity. The arc-shaped structure of the unloading trough 11 guides the sand particles to slide down the curved surface, preventing them from scattering. The anti-slip pad 12 at the bottom of the base 1 increases friction to prevent the entire equipment from slipping, ensuring stability during the tilting process. After the sand is poured out, the drive motor 35 reverses, causing the gas cylinder 4 to rotate 180 degrees back to its initial position with the open end facing upwards. Loosening the tightening bolt 34 allows the gas cylinder 4 to be removed from the support cylinder 32, completing one cleaning operation. The entire process, through the coordinated operation of the mechanical structure, achieves controllable rotation angle of the gas cylinder 4, stable clamping, and efficient unloading, solving the problems of low efficiency and poor safety associated with traditional manual operation or simple equipment.

[0042] Finally, it should be noted that the electronic components in the drive motor 35 and other components in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.
