AI Technical Summary
[0003]目前，在气瓶存放方面，多数传统灌装架采用单根铁链对气瓶进行限位，以防止其倾倒，这种限位方式在常规、平稳的操作环境下，或许能够勉强维持气瓶的稳定，然而，乙炔气瓶体积较大且重量较重，在实际使用场景中，不可避免地会面临各种复杂状况，当灌装架发生碰撞时，单根铁链的限位效果就会大打折扣，因为单根铁链的受力点相对单一，在受到较大外力冲击时，铁链容易发生晃动、变形甚至断裂，无法有效地约束气瓶，导致气瓶倾倒
[0014]本实用新型启动电动推杆后，通过固定管与连接管的联动，能同步带动两组伸缩杆下降，实现多组限位环同时下落，高效且精准，使得限位环套设于气瓶合适位置，能够适用于不同高度的气瓶，有效约束气瓶，使其在遭受外力撞击、震动时不易倾倒，极大地提升了气瓶存放的安全性与稳定性，降低安全事故风险。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas cylinder filling rack technology, specifically an acetylene gas cylinder filling rack. Background Technology
[0002] Acetylene is an important industrial gas widely used in metal cutting, welding and other operations in industrial production and many application scenarios. Acetylene is usually stored in specially designed gas cylinders in the form of compressed gas. The filling and storage management of acetylene cylinders is a key link to ensure safe and efficient production operations, and acetylene cylinder filling racks play an indispensable role in this process.
[0003] Currently, in terms of gas cylinder storage, most traditional filling racks use a single iron chain to limit the cylinder and prevent it from tipping over. This limiting method may be able to maintain the stability of the cylinder under normal and stable operating conditions. However, acetylene cylinders are large and heavy, and in actual use scenarios, they will inevitably face various complex situations. When the filling rack is involved in a collision, the limiting effect of a single iron chain will be greatly reduced because the force point of a single iron chain is relatively singular. When subjected to a large external impact, the chain is prone to shaking, deformation, or even breakage, failing to effectively restrain the cylinder and causing it to tip over.
[0004] Therefore, this utility model provides an acetylene cylinder filling rack to solve the above problems. Utility Model Content
[0005] To address the above technical problems, this utility model provides an acetylene cylinder filling rack.
[0006] To solve the above-mentioned technical problems, the present invention provides an acetylene cylinder filling rack, including a limiting frame. A base is fixedly installed at the bottom end of the limiting frame, and multiple sets of gas cylinders are arranged on the base. A first mounting frame is fixedly installed at the middle of the rear side of the base, and second mounting frames are fixedly connected to both ends of the base on both sides of the first mounting frame. An electric push rod is arranged inside the first mounting frame. A sleeve is fixedly installed on the inner wall of each of the two sets of second mounting frames, and a telescopic rod is slidably installed on the inner wall of the sleeve. A limiting ring is provided at the top end of the electric push rod and the two sets of telescopic rods.
[0007] Furthermore, a round tube is fixedly installed at the top of the electric push rod and the two sets of telescopic rods, and a connecting rod is slidably installed on the inner wall of the round tube. A limit block is fixedly installed on the outer surface of the connecting rod, and a guide groove adapted to the limit block is opened on the inner wall of the round tube. The limit block is slidably embedded in the guide groove to prevent the connecting rod from rotating. A limit ring is fixedly installed at the end of the connecting rod.
[0008] Furthermore, a threaded rod is fixedly installed at the end of the connecting rod, and a nut is rotatably installed on the threaded rod.
[0009] Furthermore, each of the multiple sets of circular tubes has a fixed tube fixedly installed at its top end, and a connecting tube is slidably installed inside the fixed tube.
[0010] Furthermore, bolts are rotatably installed on the inner walls of both ends of the connecting pipe.
[0011] Furthermore, the top of the base has multiple sets of mounting slots, and the sides of the base have multiple sets of screw holes.
[0012] Furthermore, reinforcing rods are fixedly installed on the side walls of the two sets of second mounting frames, and the reinforcing rods are fixedly connected to the top of the base.
[0013] This utility model has the following advantages compared with the prior art:
[0014] After the electric push rod is activated, the two sets of telescopic rods can be driven to descend simultaneously through the linkage of the fixed tube and the connecting tube, so that multiple sets of limit rings can fall at the same time. This is efficient and precise, so that the limit rings are fitted into the appropriate position of the gas cylinder. It can be used for gas cylinders of different heights, effectively restraining the gas cylinder and making it less likely to tip over when subjected to external impact or vibration. This greatly improves the safety and stability of gas cylinder storage and reduces the risk of safety accidents. Attached Figure Description

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] like Figures 1 to 4The acetylene cylinder filling rack shown includes a limiting frame 1, a base 2 fixedly mounted at the bottom end of the limiting frame 1, and multiple sets of gas cylinders 11 arranged on the base 2. A first mounting frame 3 is fixedly mounted at the middle of the rear side of the base 2, and second mounting frames 4 are fixedly connected to both ends of the base 2 on both sides of the first mounting frame 3. An electric push rod 6 is arranged inside the first mounting frame 3. The electric push rod 6 serves as a power source, providing stable and controllable linear motion to power the lifting and lowering action of the limiting ring 8. The inner walls of both sets of second mounting frames 4 are fixedly mounted with... The sleeve 41 has a telescopic rod 42 slidably installed on its inner wall. The electric push rod 6 and the top of the two sets of telescopic rods 42 are all equipped with limit rings 8. The limit rings 8 act directly on the gas cylinder 11, constraining and limiting the gas cylinder 11 from multiple directions, effectively preventing the gas cylinder 11 from tipping over when subjected to external impacts or vibrations. This greatly improves the safety and stability of the gas cylinder 11 during storage and reduces the risk of safety accidents caused by the tipping of the gas cylinder 11. The inner ring of the limit ring 8 can also be equipped with a rubber pad to reduce collision impacts and avoid damage to the cylinder body.
[0022] To facilitate the disassembly of the limiting ring 8, a circular tube 83 is fixedly installed at the top of the electric push rod 6 and the two sets of telescopic rods 42. A connecting rod 81 is slidably installed on the inner wall of the circular tube 83, and a limiting block 82 is fixedly installed on the outer surface of the connecting rod 81. A guide groove adapted to the limiting block 82 is opened on the inner wall of the circular tube 83. The limiting block 82 is slidably embedded in the guide groove to prevent the connecting rod 81 from rotating, thus ensuring the stability of the limiting ring 8 during installation and use and ensuring that it can accurately perform its limiting function. The limiting ring 8 is fixedly installed at the end of the connecting rod 81. When it is necessary to disassemble the limiting ring 8, simply pull the connecting rod 81 out of the circular tube 83. The operation is convenient and quick.
[0023] In order to ensure that the limiting ring 8 is fixedly installed inside the round tube 83, a threaded rod 84 is fixedly installed at the end of the connecting rod 81, and a nut 85 is rotatably installed on the threaded rod 84. When the connecting rod 81 is inserted into the round tube 83, tightening the nut 85 can firmly fix the connecting rod 81 inside the round tube 83, preventing the connecting rod 81 from loosening or falling off during use, thereby ensuring the reliability of the connection between the limiting ring 8 and the round tube 83.
[0024] In order for the two sets of telescopic rods 42 and electric push rods 6 to move synchronously, the top ends of multiple sets of round tubes 83 are fixedly installed with fixed tubes 72, and connecting tubes 7 are slidably installed inside the fixed tubes 72. The combination of fixed tubes 72 and connecting tubes 7 forms a linkage mechanism that can transmit the movement of electric push rods 6 to the two sets of telescopic rods 42, so as to realize the synchronous movement of the three. The synchronous movement design ensures that the limiting rings 8 can descend or rise simultaneously and evenly, so that each gas cylinder 11 can be subject to the same degree of limiting effect.
[0025] In order for the connecting pipe 7 to be fixedly installed inside the fixed pipe 72, bolts 71 are rotatably installed on the inner walls of both ends of the connecting pipe 7. By rotating the bolts 71, the connection of the connecting pipe 7 inside the fixed pipe 72 can be strengthened, ensuring the stability and reliability of the connection between the connecting pipe 7 and the fixed pipe 72.
[0026] To initially limit the position of the gas cylinder 11, multiple sets of mounting slots 21 are provided at the top of the base 2. The depth or height of the mounting slots 21 is not less than 20cm, which further increases the stability during initial positioning. The gas cylinder 11 is placed in the mounting slots 21, which can initially position and fix the gas cylinder 11. In addition, multiple sets of screw holes 22 are provided on both sides of the base 2. The multiple sets of screw holes 22, together with the screws, can fix the base 2 on the ground, which improves the stability and safety of the entire filling rack.
[0027] To increase the stability of the second mounting frame 4, reinforcing rods 5 are fixedly installed on the side walls of the two sets of second mounting frames 4, and the reinforcing rods 5 are fixedly connected to the top of the base 2, forming a more stable triangular structure that can effectively disperse and bear the external force on the second mounting frame 4, preventing the second mounting frame 4 from deforming or shaking during use.
[0028] The working process of this embodiment is as follows:
[0029] First, multiple sets of acetylene cylinders 11 are placed sequentially into the pre-drilled mounting slots 21 on the base 2 to initially position the cylinders 11. After the cylinders 11 are placed, the electric push rod 6 located in the first mounting frame 3 is activated. The electric push rod 6 begins to work, and its output end moves downward in a straight line and gradually descends. A round tube 83 is fixedly installed at the top of the electric push rod 6. The round tube 83 is connected to the connecting tube 7 through a fixed tube 72. As the electric push rod 6 descends, the fixed tube 72 descends accordingly, thereby driving the connecting tube 7 to descend as well. Both ends of the connecting pipe 7 are connected to the round pipes 83 installed at the top of the telescopic rods 42 in the two sets of second mounting frames 4, so that the connecting pipe 7 and the round pipes 83 form a stable linkage. Therefore, when the connecting pipe 7 descends, it can synchronously drive the two sets of telescopic rods 42 to slide downward in the sleeve 41, realizing synchronous descent. The electric push rod 6 and the inner wall of the round pipes 83 fixedly installed at the top of the two sets of telescopic rods 42 are slidably installed with connecting rods 81. The outer surface of the connecting rods 81 is fixedly installed with limit blocks 82. The inner wall of the round pipes 83 is provided with guide grooves that are adapted to the limit blocks 82. The sliding fitting within the guide groove effectively prevents the connecting rod 81 from rotating within the circular tube 83, ensuring structural stability. As the electric push rod 6 and the telescopic rod 42 descend synchronously, the limiting ring 8 also descends and gradually fits onto the outside of the gas cylinder 11. Once the limiting ring 8 is fully fitted into the appropriate position on the gas cylinder 11, the operation of the electric push rod 6 is stopped. At this point, the limiting ring 8 effectively constrains and limits the gas cylinder 11, preventing it from easily tipping over even under external impacts or vibrations, thus greatly improving the safety and stability of the gas cylinder 11 during storage.
