Description

Technical Field

[0001] This utility model relates to the field of auxiliary storage and protection for industrial equipment, and in particular to a protective bracket for preventing gas cylinders from tipping over. Background Technology

[0002] The sintering area of ​​the ironmaking plant is a crucial link in steel production. It not only occupies a large area but also encompasses core systems such as feeding, primary mixing, secondary mixing (granulation), sintering (including main pumping), annular cooling, and screening (including bottom material laying). These systems are interconnected via belt drives and are also equipped with auxiliary systems for waste heat recovery and dust removal. The equipment is complex and diverse, resulting in heavy daily maintenance tasks. During maintenance, a large number of flammable and explosive gas cylinders such as oxygen and acetylene cylinders are used. The proper storage of these cylinders directly affects the safety of personnel and the production order in the work area. Improper storage can easily lead to leaks, explosions, and other safety accidents. Therefore, high requirements are placed on the anti-tipping performance of the cylinder storage racks.

[0003] In the prior art, Chinese utility model patent with publication number CN222085773U discloses an anti-tipping device for oxygen cylinders. This device mainly consists of a frame, a buffer pad, and a horizontal bolt. The internal space of the frame is divided into several C-shaped grids, the structural dimensions of which are adapted to the oxygen cylinder for positioning. The buffer pad is fixedly installed on the inner wall of the C-shaped grids to reduce collision damage between the oxygen cylinder and the grid walls. The horizontal bolt is installed in grooves on both sides of the opening of the C-shaped grid using a snap-fit ​​method. When the horizontal bolt is engaged in the groove, it blocks the oxygen cylinder from tipping over. When the oxygen cylinder needs to be replaced, simply remove the horizontal bolt to remove the cylinder.

[0004] However, the anti-tipping devices in the aforementioned existing technologies still have significant drawbacks: they rely on horizontal bolts to secure the gas cylinders, but a large gap always exists between the bolts and the cylinders, making it impossible to achieve a tight fit and clamping. Even if the cylinders are placed normally within the C-shaped grid, they may still wobble or even tip over within the gap due to personnel movement in the work area, equipment vibration, or minor collisions. This makes it difficult to meet the high-safety storage requirements for gas cylinders during maintenance in the sintering work area of ​​an ironmaking plant, and certain operational risks remain. Utility Model Content

[0005] This application provides a protective bracket for preventing gas cylinders from tipping over, which solves the technical problem in the prior art that gas cylinders may shake or even tip over, and improves the stability of gas cylinders stored in the maintenance scenario of the sintering operation area of ​​an ironmaking plant.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a protective bracket for preventing gas cylinder tipping, comprising a base plate and a frame, the frame being fixed above the base plate, and the frame being divided into multiple placement positions for placing gas cylinders; each placement position has a lower arc baffle at the bottom and an upper arc baffle at the top, the lower and upper arc baffles having the same opening direction and their arc curvature adapting to the outer wall of the gas cylinder; each placement position also has a "U"-shaped movable arc baffle, the movable arc baffle sliding horizontally with the frame, and the opening direction of the movable arc baffle being opposite to that of the lower and upper arc baffles; both sides of the opening end of the movable arc baffle are connected to the frame by tension springs, the tension springs being able to pull the movable arc baffle towards the center of the placement position in its natural state, so that the movable arc baffle, together with the lower and upper arc baffles, clamps the gas cylinder.

[0007] In use, the operator first pulls the movable arc baffle away from the placement position, stretching the tension spring. Then, the gas cylinder is placed into the placement position from the opening side of the lower and upper arc baffles. After releasing the movable arc baffle, the tension spring, under the action of the restoring elastic force, pulls the movable arc baffle closer to the gas cylinder until the movable arc baffle, the lower arc baffle, and the upper arc baffle all fit against the outer wall of the gas cylinder, thus clamping and fixing the gas cylinder. Because the movable arc baffle slides horizontally with the frame, and the tension spring can continuously pull the movable arc baffle towards the center of the placement position in its natural state, the movable arc baffle always fits tightly against the outer wall of the gas cylinder. There is no gap between the horizontal bolt and the gas cylinder in the prior art. Therefore, the gas cylinder can be stably clamped from three different height positions, effectively reducing the risk of the gas cylinder tipping over.

[0008] As a further improvement to the above solution, a guide crossbar is fixed inside the frame along the sliding direction of the movable arc baffle. The upper and lower bottom surfaces of the guide crossbar are provided with grooves extending along the length direction. A slider is provided on the inner side wall of the movable arc baffle. The slider size is adapted to the groove and is locked into the groove. This can effectively prevent the movable arc baffle from shifting during the sliding process and ensure that it always maintains a horizontal sliding state.

[0009] As a further improvement to the above solution, a handle is fixed to the outer side of the arc segment of the movable arc baffle away from the opening end; thus, when the operator needs to pull the movable arc baffle to put in or take out the gas cylinder, he / she can directly apply force to the handle.

[0010] As a further improvement to the above solution, the handle includes a strip plate and two connecting plates; the two connecting plates are fixed at both ends of the strip plate along its length, and the connecting plate away from the strip plate is fixed to a movable arc baffle; a groove is provided on the outer surface of the strip plate, and an identification plate can be inserted into the groove; thus, the type of gas cylinder in different placement positions can be quickly distinguished by the identification plate, which can effectively prevent the risk of misuse caused by confusion of gas cylinders.

[0011] As a further improvement to the above solution, the outer surfaces of the upper arc baffle, the lower arc baffle, and the movable arc baffle are all covered with a buffer layer; the buffer layer is made of rubber or sponge material; thus, during the process of the gas cylinder being placed in the placement position and contacting each arc baffle, and during the process of the movable arc baffle clamping the gas cylinder, the buffer layer can isolate the hard contact with the outer wall of the gas cylinder, effectively reducing the impact and friction damage to the gas cylinder.

[0012] As a further improvement to the above solution, an anti-slip silicone pad is attached to the upper surface of the base plate. The anti-slip silicone pad can cover the area where the base plate contacts the bottom of the gas cylinder. The silicone material can significantly increase the friction between the bottom of the gas cylinder and the base plate. Even if the protective bracket is slightly bumped or vibrated in the sintering operation area of ​​the ironmaking plant, it can effectively prevent the gas cylinder from sliding on the base plate.

[0013] As a further improvement to the above solution, "L"-shaped chain hooks are fixed on the left and right sides of the top of the frame, and protective chains are fitted on the chain hooks; the length of the protective chain is greater than the distance between the chain hooks on the two sides of the top of the frame; the protective chain can form a horizontal protective barrier at the top of the frame, so that even if the moving arc baffle cannot tightly clamp the gas cylinder due to unexpected situations such as spring failure, the protective chain can prevent the gas cylinder from tipping over from the placement position from the top.

[0014] As a further improvement to the above solution, ear plates are fixed on both sides of the frame, and the ear plates are provided with through holes for expansion bolts to pass through; thereby, the entire protective bracket can be firmly fixed to the wall or ground, and can effectively prevent the protective bracket itself from tipping over in the sintering operation area of ​​the ironmaking plant due to personnel walking, equipment collisions, etc.

[0015] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages: In use, the operator first pulls the movable arc baffle away from the placement position, stretching the tension spring. Then, the gas cylinder is placed into the placement position from the opening side of the lower and upper arc baffles. After releasing the movable arc baffle, the tension spring, under the action of the restoring elastic force, pulls the movable arc baffle closer to the gas cylinder until the movable arc baffle, the lower arc baffle, and the upper arc baffle all fit against the outer wall of the gas cylinder, thus clamping and fixing the gas cylinder. Because the movable arc baffle slides horizontally with the frame, and the tension spring can continuously pull the movable arc baffle towards the center of the placement position in its natural state, the movable arc baffle always fits tightly against the outer wall of the gas cylinder. There is no gap between the horizontal bolt and the gas cylinder in the prior art. Therefore, the gas cylinder can be stably clamped from three different height positions, effectively reducing the risk of the gas cylinder tipping over. Attached Figure Description

Detailed Implementation To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0018] This utility model discloses a protective bracket for preventing gas cylinders from tipping over, which includes a base plate 1 and a frame 2. The frame 2 is fixed above the base plate 1 and is divided into multiple placement positions. Each placement position is provided with a lower arc baffle 3 and an upper arc baffle 4 at its bottom and top, respectively. The openings of the lower arc baffle 3 and the upper arc baffle 4 face the same direction. Each placement position is also provided with a U-shaped movable arc baffle 5. The movable arc baffle 5 slides horizontally with the frame 2. The opening direction of the movable arc baffle 5 is opposite to the opening direction of the lower arc baffle 3 and the upper arc baffle 4. Both sides of the opening of the movable arc baffle 5 are connected to the frame 2 by tension springs 6.

[0019] In this embodiment, as Figure 1 , Figure 6 As shown, the base plate 1 is a rectangular plate structure. The frame 2 is welded and fixed to the upper surface of the base plate 1 by multiple metal rods. The interior of the frame 2 is divided into four independent placement positions by vertical metal rods. The size of each placement position is adapted to the outer diameter of a conventional gas cylinder 13. A lower arc baffle 3 is welded and fixed to the bottom of each placement position (i.e., the corresponding position above the base plate 1), and an upper arc baffle 4 is welded and fixed to the top of the placement position (i.e., the corresponding position below the horizontal bar of the frame 2). The arc curvature of the lower arc baffle 3 and the upper arc baffle 4 is consistent with the arc curvature of the outer wall of the gas cylinder 13, and the openings of both face the same side of the frame 2 to realize the insertion and removal of the gas cylinder 13. Each placement position is also equipped with a U-shaped movable arc baffle 5. The arc of the movable arc baffle 5 is also adapted to the outer wall of the gas cylinder 13, and its opening direction is opposite to that of the lower arc baffle 3 and the upper arc baffle 4. The two sides of the movable arc baffle 5 are connected to the frame 2 through a horizontal sliding structure, and can move horizontally along the frame 2. Hanging rings are welded to the two sides of the opening of the movable arc baffle 5, and hanging rings are also welded to the corresponding positions of the frame 2. The two ends of the tension spring 6 are respectively hooked onto the hanging rings of the movable arc baffle 5 and the frame 2. In its natural state, the tension spring 6 can pull the movable arc baffle 5 closer to the center of the placement position.

[0020] In actual use, the operator first pulls the movable arc baffle 5 away from the placement position. At this time, the tension spring 6 is stretched, and the movable arc baffle 5, the lower arc baffle 3, and the upper arc baffle 4 form a space sufficient to accommodate the gas cylinder 13. Then, the gas cylinder 13 is placed into the placement position from the opening side of the lower arc baffle 3 and the upper arc baffle 4, so that the bottom of the gas cylinder 13 is in contact with the bottom plate 1, and the outer wall of the gas cylinder 13 is in contact with the inner wall of the lower arc baffle 3 and the upper arc baffle 4. The movable arc baffle 5 is released, and the tension spring 6 pulls the movable arc baffle 5 closer to the gas cylinder 13 under the action of the reset elastic force until the inner wall of the movable arc baffle 5 is in contact with the outer wall of the gas cylinder 13. At this time, the gas cylinder 13 is clamped and fixed by the lower arc baffle 3, the upper arc baffle 4, and the movable arc baffle 5 from three positions at different heights. When it is necessary to remove the gas cylinder 13, pull the movable arc baffle 5 again to stretch the tension spring 6, and the gas cylinder 13 can be removed from the placement position.

[0021] In the above structure, by setting a movable arc baffle 5 with the opposite opening direction to the lower arc baffle 3 and the upper arc baffle 4, and with the elastic force of the tension spring 6, the gas cylinder 13 can be tightly clamped, effectively solving the problem of the gas cylinder being easy to tip over due to the gap between the horizontal bolt and the gas cylinder in the prior art.

[0022] Furthermore, such as Figures 2 to 4As shown, the frame 2 has a guide crossbar 7 inside, which is horizontally fixed between the vertical bars inside the frame 2, and the length direction of the guide crossbar 7 is consistent with the sliding direction of the movable arc baffle 5. The upper and lower surfaces of the guide crossbar 7 are respectively provided with rectangular grooves 701 extending along its length direction. The length of the grooves 701 is greater than the maximum sliding distance of the movable arc baffle 5. Slider blocks 501 are respectively provided on the inner walls of both sides of the movable arc baffle 5. The sliders 501 are rectangular block structures, and their dimensions are adapted to the dimensions of the grooves 701. The sliders 501 can be inserted into the grooves 701 from one end of the guide crossbar 7 and can slide along the grooves 701.

[0023] In the above structure, the groove 701 of the guide bar 7 cooperates with the slider 501 of the movable arc baffle 5 to provide guidance for the sliding of the movable arc baffle 5, prevent the movable arc baffle 5 from shifting up or down or tilting during the sliding process, and ensure that the movable arc baffle 5 always moves in the horizontal direction, thereby ensuring its stability and clamping effect when it is in contact with the gas cylinder 13.

[0024] Furthermore, a handle 8 is fixed to the end of the movable arc-shaped baffle 5 away from the opening. Specifically, the handle 8 is fixed at the center of the outer side of the arc segment of the movable arc-shaped baffle 5 away from the opening, and the fixing method can be welding. The handle 8 provides a convenient point of force for the operator to pull the movable arc-shaped baffle 5. Compared with directly pulling the side of the movable arc-shaped baffle 5, the handle 8 can reduce the operator's hand fatigue and avoid the hand from scratching the edge of the movable arc-shaped baffle 5 during the pulling process, thus improving the safety and convenience of operation.

[0025] More specifically, the handle 8 includes a strip plate 801 and connecting plates 802 fixed at both ends of the strip plate 801 along its length. The strip plate 801 is a rectangular metal plate, the length of which is less than the length of the arc segment of the movable arc baffle 5. The connecting plate 802 is also a rectangular metal plate. One end of the connecting plate 802 is welded to the end of the strip plate 801, and the other end is welded to the outer side of the arc segment of the movable arc baffle 5. A rectangular groove is formed on the outer surface of the strip plate 801, and a label can be inserted into the groove. The label can be marked with "oxygen," "acetylene," etc. By marking "oxygen," "acetylene," etc., on the label, the types of gas cylinders such as oxygen and acetylene in different placement positions can be quickly distinguished, avoiding the risk of use due to confusion of gas cylinders.

[0026] Furthermore, the outer surfaces of the upper arc-shaped baffle 4, the lower arc-shaped baffle 3, and the movable arc-shaped baffle 5 are all covered with a buffer layer. The buffer layer can be made of rubber or sponge and is attached using adhesive. This buffer layer effectively reduces hard collisions and friction between the gas cylinder 13 and the arc-shaped baffles, preventing scratches or deformation of the outer wall of the gas cylinder 13 due to impact. Simultaneously, the rubber or sponge buffer layer provides a certain degree of slip resistance, further enhancing the clamping stability of the gas cylinder 13 and reducing slight shaking of the gas cylinder 13 within its placement position.

[0027] Furthermore, an anti-slip silicone pad 9 is attached to the upper surface of the base plate 1. The anti-slip silicone pad 9 can significantly increase the friction between the bottom of the gas cylinder 13 and the base plate 1, effectively preventing the gas cylinder 13 from sliding on the base plate 1 even if the support is slightly bumped. It forms a double protection with the clamping effect of the arc baffle, further reducing the risk of the gas cylinder 13 tipping over. At the same time, the silicone material has good aging resistance and corrosion resistance, and can adapt to the complex environment of the sintering operation area of ​​the ironmaking plant.

[0028] In addition, chain hooks 10 are fixed to the left and right sides of the top of the frame 2, and protective chains 11 can be fitted onto the chain hooks 10. Figure 1 , Figure 5 As shown, the chain hooks 10 are L-shaped hooks. One end of each hook is welded to the left and right sides of the top of the frame 2. The length of the protective chain 11 is greater than the distance between the chain hooks 10 on the left and right sides of the top of the frame 2, so that both ends of the protective chain 11 can be inserted into the corresponding chain hooks 10 on both sides. When the protective chain 11 is inserted into the chain hooks 10, it forms an additional protective barrier on the top of the frame 2. Even if the movable arc baffle 5 cannot clamp the gas cylinder 13 due to reasons such as the failure of the tension spring 6, the protective chain 11 can still prevent the gas cylinder 13 from tipping over from the top of the placement position, achieving double protection and further improving the safety of gas cylinder storage. At the same time, the protective chain 11 is easy to disassemble and install, and does not affect the normal access to the gas cylinder 13.

[0029] In other embodiments, such as Figure 1 As shown, two ear plates 12 are fixed to each of the left and right sides of the frame 2. One side of the ear plate 12 is fixedly connected to the vertical rod of the frame 2 by welding, and the other side of the ear plate 12 extends outward from the frame 2. A circular through hole is opened at the center of each ear plate 12. The diameter of the through hole is adapted to the outer diameter of a conventional expansion bolt. In use, the expansion bolt can be passed through the through hole to fix the ear plate 12 to a fixed base on the wall or the ground, thereby achieving the fixation of the entire bracket. In the above structure, fixing the bracket to the wall or the ground by the ear plates 12 and the expansion bolts can prevent the bracket itself from tipping over due to collision, fundamentally avoiding the risk of the gas cylinder 13 falling due to the bracket tipping over.
