Description

Technical Field

[0001] This application relates to the field of gas filling technology, and in particular to a cylinder fixing device for industrial gas filling. Background Technology

[0002] In industrial gas filling operations, oxygen and carbon dioxide filling are common, and gas filling manifolds are the equipment used to complete this operation. Under current technological conditions, when a gas filling manifold is filling a cylinder with oxygen or carbon dioxide, keeping the cylinder stable by placing it on a stable base such as a standard pad is a common practice.

[0003] Currently, during the gas filling process, the gas cylinder is usually placed on a standard pad under the gas filling manifold. The standard pad mainly serves a simple support function, and its design purpose is only to ensure the basic stability of the gas cylinder when it is placed.

[0004] However, in actual operation, as gas is continuously filled into the cylinder, the internal pressure gradually increases, causing some shaking or vibration. The standard pad can only provide basic support and cannot effectively secure the cylinder. This means that the user needs to continuously hold the cylinder by hand during the filling process to maintain its stability. This not only increases the workload of the operator, but also makes the operator prone to fatigue and negligence during prolonged holding, leading to the cylinder tipping over, gas leakage, and waste.

[0005] Furthermore, because the position of the gas cylinder on the standard pad is not completely fixed and precise, the cylinder needs to be adjusted when connecting the valve so that the valve can connect. This process requires moving the cylinder, which is time-consuming and labor-intensive, reducing filling efficiency.

[0006] Furthermore, the standard pads are usually fixed in position and are not easy to move. When it is necessary to transport the cylinders from outside the workshop to the standard pads for filling, the user has to lift and place the cylinders on the standard pads manually. For cylinders that are large in size and heavy in weight, manual lifting and placing is labor-intensive and inconvenient.

[0007] To address the aforementioned issues, a cylinder fixing device for industrial gas filling is now designed. Utility Model Content

[0008] This application provides a cylinder fixing device for industrial gas filling, in order to solve the problem in the related art that the cylinder will shake or vibrate during the filling process, requiring the user to hold the cylinder continuously.

[0009] In a first aspect, a cylinder fixing device for industrial gas filling is provided, comprising:

[0010] A slide rail arranged below the gas filling manifold, and a frame that slides in cooperation with the slide rail;

[0011] The frame is provided with a through hole for positioning the steel cylinder, and the bottom of the frame is provided with a bracket for supporting the steel cylinder.

[0012] The frame is provided with a fixing mechanism, which includes a frame body on the frame, an arc-shaped groove for accommodating the steel cylinder, and a fixing ring hinged to the frame body. The fixing ring and the arc-shaped groove together form a defined channel for fixing the body of the steel cylinder.

[0013] In some embodiments, the frame includes a base that is n-shaped, with pivots arranged around the base and wheels rotatably mounted at the other end of the pivots.

[0014] In some embodiments, a slider is also provided at the bottom of the frame, the slider is adapted to the slide rail, and mounting rods connected to the base are provided around the slider.

[0015] In some embodiments, the bracket is disposed on the base, between the through hole and the slider, the bracket is U-shaped, and a rubber pad is disposed above the bracket.

[0016] In some embodiments, the frame includes two upright plates disposed opposite each other on the vehicle frame, a horizontal plate is disposed between the two upright plates, the arc-shaped groove is formed on the horizontal plate, and the fixing ring is arranged opposite to the arc-shaped groove.

[0017] In some embodiments, the fixing ring is semi-circular, a sleeve is provided at one end of the fixing ring, two fixing blocks are arranged opposite each other on the horizontal plate, a pin is provided between the two fixing blocks, and the sleeve is sleeved on the pin and rotates with it.

[0018] A fixing plate is provided at the other end of the fixing ring, and a positioning plate is provided on the horizontal plate. Both the fixing plate and the positioning plate have symmetrical insertion holes, and a limit rod is inserted into the insertion holes.

[0019] This application provides a cylinder fixing device for industrial gas filling. The cylinder is initially positioned by the through hole on the frame, making the position of the cylinder on the frame relatively accurate. The bracket supports the cylinder from below, sharing the weight of the cylinder. The cylinder body is firmly fixed by the limiting channel formed by the fixing ring and the arc groove, which avoids the cylinder shaking during the filling process, making it convenient to use and safer.

[0020] By pushing the frame along the slide rail, the cylinder can be moved to the bottom of the valve, thus connecting the cylinder and the valve. This reduces the time spent on repeated adjustments due to inaccurate connection and improves the efficiency of the filling operation. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] This application provides a cylinder fixing device for industrial gas filling, which can solve the problem in related technologies that the cylinder will shake or vibrate during the filling process, requiring the user to hold the cylinder continuously.

[0030] Please see Figure 1 , Figure 2 and Figure 5As shown, an industrial gas filling cylinder fixing device includes: a slide rail 1 arranged below the gas filling manifold, and a frame 2 that slides with the slide rail 1; the frame 2 is provided with a through hole 3 for positioning the cylinder, and a bracket 4 for supporting the cylinder is provided at the bottom of the frame 2; the frame 2 is provided with a fixing mechanism 5, which includes a frame body 51 on the frame 2, an arc-shaped groove 52 for accommodating the cylinder on the frame body 51, and a fixing ring 53 hinged on the frame body 51. The fixing ring 53 and the arc-shaped groove 52 together form a limiting channel 54 for fixing the cylinder body.

[0031] Inside the industrial gas filling workshop, a slide rail 1 is arranged below the gas filling manifold. The frame 2 slides along the slide rail 1, allowing the frame 2 to move along the slide rail 1.

[0032] When it is necessary to transport the gas cylinder to the gas filling position, the operator can place the gas cylinder on the frame 2. The through hole 3 set on the frame 2 serves as a positioning function. The operator places the bottom of the gas cylinder roughly aligned with the through hole 3.

[0033] After the gas cylinder is placed on the frame 2, the bracket 4 supports the gas cylinder from below, sharing part of the weight of the gas cylinder, ensuring the stability of the gas cylinder on the frame 2, and preventing the gas cylinder from falling off due to shaking during movement.

[0034] After the gas cylinder is placed on the frame 2 and initially positioned, the operator rotates the fixing ring 53 hinged on the frame 51 around the hinge point, causing the fixing ring 53 to move closer to the arc-shaped groove 52 until the fixing ring 53 and the arc-shaped groove 52 form a limiting channel 54, firmly fixing the gas cylinder body within it. At this point, the gas cylinder is securely restrained on the frame 2 and cannot be shaken or moved at will.

[0035] The frame 2 is pushed to move along the slide rail 1, so that the steel cylinder on the frame 2 is accurately moved to the bottom of the gas filling manifold, realizing the docking of the steel cylinder and the gas nozzle. During the filling process, since the steel cylinder has been firmly fixed by the fixing mechanism 5 and the bracket 4 provides stable support, the steel cylinder will not shake or shift due to pressure changes during filling, ensuring the safety and stability of the filling process.

[0036] The through hole 3 on the frame 2 provides initial positioning for the cylinder, making the cylinder relatively accurate in position on the frame 2. The bracket 4 supports the cylinder from below, sharing the weight of the cylinder. The cylinder body is firmly fixed by the limiting channel 54 formed by the fixing ring 53 and the arc groove 52, which prevents the cylinder from shaking during filling, making it convenient to use and safer.

[0037] By pushing the frame 2 along the slide rail 1, the cylinder can be moved to the bottom of the gas nozzle, thus achieving the connection between the cylinder and the gas nozzle. This reduces the time spent on repeated adjustments due to inaccurate connection and improves the efficiency of the filling operation.

[0038] When the gas cylinder is transported from the filling workshop to the filling station, the operator only needs to gently push the frame 2 to easily transport the gas cylinder to the gas filling position through the sliding cooperation between the frame 2 and the slide rail 1. This eliminates the need for the user to handle the gas cylinder, saving manpower and time and improving transportation efficiency.

[0039] like Figure 1 and Figure 2 As shown, the frame 2 in this embodiment includes a base 21, which is n-shaped. A pivot 22 is provided around the base 21, and a wheel 23 is rotatably mounted on the other end of the pivot 22.

[0040] The base 21 serves as the supporting structure for the frame 2, providing a stable basic framework for the entire device.

[0041] When the frame 2 needs to be moved, the operator applies external force to push or pull the frame 2. At this time, the wheels 23 begin to roll under the action of ground friction. Due to the rotational connection of the axle 22, the wheels 23 can change the direction of rotation according to the direction of pushing or pulling, thereby realizing the movement of the frame 2.

[0042] like Figure 1 and Figure 2 As shown, the bottom of the frame 2 is further provided with a slider 24, which is adapted to the slide rail 1, and mounting rods 25 connected to the base 21 are provided around the slider 24.

[0043] The shape and size of the slider 24 match the slide rail 1, allowing it to fit snugly and smoothly onto the slide rail 1.

[0044] When the cylinder needs to be transported to the gas filling position, push the frame 2, and the slider 24 will slide in a straight line along the extension direction of the slide rail 1. Since the slide rail 1 guides the slider 24, the frame 2 can only move along the path set by the slide rail 1, thus ensuring that the cylinder can be accurately transported to the bottom of the gas filling manifold and connected with the gas nozzle.

[0045] The mounting rod 25 secures the slider 24 to the bottom of the frame 2, ensuring a firm and reliable connection between the slider 24 and the frame 2.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment, the bracket 4 is disposed on the base 21, located between the through hole 3 and the slider 24. The bracket 4 is U-shaped, and a rubber pad 41 is disposed above the bracket 4.

[0047] The bracket 4 is set on the base 21, between the through hole 3 and the slider 24, and directly below the through hole 3, to ensure that the steel cylinder can be stably within the support range of the bracket 4 through the limiting of the through hole 3 and the support of the bracket 4 during the movement of the frame 2.

[0048] When the cylinder is placed on the bracket 4, the bottom of the cylinder will enter the groove of the U-shaped bracket 4, so that the cylinder is constrained by both sides of the bracket 4 in the horizontal direction.

[0049] The rubber pad 41 plays an important role in cushioning and protecting the cylinder during placement. When the cylinder is placed on the bracket 4, the rubber pad 41 undergoes a certain degree of elastic deformation, absorbing the impact force generated during placement and reducing the hard collision between the cylinder and the bracket 4.

[0050] like Figure 1 and Figure 2 As shown, in one embodiment, the frame 51 includes two upright plates 511 disposed opposite to each other on the frame 2, a horizontal plate 512 disposed between the two upright plates 511, an arc-shaped groove 52 formed on the horizontal plate 512, and a fixing ring 53 arranged opposite to the arc-shaped groove 52.

[0051] Two upright plates 511 are vertically fixed to the frame 2, providing vertical support for the entire frame 51 and ensuring that the frame 51 remains stable during the movement of the frame 2.

[0052] The horizontal plate 512 is horizontally positioned between the two vertical plates 511, serving as a connection and load-bearing structure, and providing a base plane for the installation of the arc-shaped groove 52.

[0053] An arc-shaped groove 52 is formed on the horizontal plate 512, and its shape is adapted to the outer contour of the gas cylinder. When the gas cylinder is placed near the frame 51, the operator can insert the side of the gas cylinder into the arc-shaped groove 52 to restrict the left and right movement of the gas cylinder in the horizontal plane, so that the gas cylinder is roughly in a fixed position.

[0054] The fixing ring 53 is arranged opposite to the arc-shaped groove 52, and its function is to cooperate with the arc-shaped groove 52 to further fix the steel cylinder.

[0055] Specifically, after the arc-shaped groove 52 is embedded in the bottom of the cylinder, the operator rotates the fixing ring 53 and puts it on the corresponding part of the cylinder. The fixing ring 53 constrains the cylinder from the other side and forms a complete limiting channel 54 with the arc-shaped groove 52, ensuring that the cylinder will not shake, roll or fall off during the movement of the frame 2.

[0056] like Figure 3 and Figure 4As shown, in one embodiment, the fixing ring 53 is semi-circular, and a sleeve 531 is provided at one end of the fixing ring 53. Two fixing blocks 532 are arranged opposite each other on the horizontal plate 512, and a pin 533 is provided between the two fixing blocks 532. The sleeve 531 is sleeved on the pin 533 and rotates with it.

[0057] A fixing piece 534 is provided at the other end of the fixing ring 53, and a positioning piece 535 is provided on the horizontal plate 512. Both the fixing piece 534 and the positioning piece 535 are provided with symmetrical insertion holes 536, and a limit rod 537 is inserted into the insertion hole 536.

[0058] A pin 533 is installed between the two fixed blocks 532, and a sleeve 531 is fitted onto the pin 533. The two are in a rotating fit relationship, so that the fixed ring 53 can rotate around the pin 533 as the axis.

[0059] When it is necessary to secure the gas cylinder, the operator can rotate the retaining ring 53 around the pin 533 to rotate the retaining ring 53 from the open state to the closed state, thereby surrounding the gas cylinder; when it is necessary to remove the gas cylinder, the retaining ring 53 is rotated in the opposite direction to open the retaining ring 53, making it easier to remove the gas cylinder.

[0060] When the retaining ring 53 rotates to the closed state and the bottom of the retaining plate 534 is in contact with the surface of the positioning plate 535, the operator can insert the limiting rod 537 into the insertion hole 536 of both. The limiting rod 537 passes through the insertion hole 536 on the retaining plate 534 and the positioning plate 535, thereby fixing this end of the retaining ring 53 to the cross plate 512, preventing the retaining ring 53 from opening on its own due to the shaking of the gas cylinder during the movement of the frame 2, and ensuring the reliability of the gas cylinder fixation.

[0061] The fixing ring 53 is opened and closed through the rotational cooperation between the sleeve 531 and the pin 533, and the fixing ring 53 can be easily rotated to complete the fixing and removal of the cylinder.

[0062] The closed state of the fixing ring 53 is fixed by inserting the limiting rod 537 into the insertion hole 536 on the fixing piece 534 and the positioning piece 535. This method is simple and effective.

[0063] The symmetrically arranged insertion holes 536 and the limiting rod 537 work together to constrain the fixing ring 53 in the vertical direction, further enhancing the stability of the fixation and ensuring that the cylinder remains stable during transportation or filling.

[0064] By extending the length of the limiting rod 537 to a certain extent, the fixing ring 53 is prevented from loosening or opening due to vibration or the shaking of the cylinder during the movement of the frame 2.
