Description

Technical Field

[0001] This utility model relates to the technical field of rapid repair tools for flange leaks in railway freight car piping systems. Background Technology

[0002] After the main air pressure of railway freight cars was standardized from 500 kPa to 600 kPa across the entire railway network, the phenomenon of air leakage in the piping system flanges increased significantly. Most of these air leakage faults were caused by the aging and hardening of the flange sealing ring material, edge biting, damage, and improper original installation. After the standardized air pressure was increased to 600 kPa, as the air pressure of the piping system further increased, the above-mentioned hidden dangers gradually evolved into piping system air leakage faults.

[0003] Troubleshooting this type of piping leak requires replacing the flange sealing ring. After the flange bolts loosen, tension exists at the pipe joint, necessitating the use of specialized tools to create sufficient gaps between the ducts on both sides of the flange to quickly remove the damaged sealing ring and install a new one. Previously, this type of fault required a manual hoist, but this tool is large, heavy, cumbersome to install, demands high operator skills, and is unreliable. Especially when carrying this tool over long distances for emergency handling, it is physically demanding, time-consuming, and disruptive to railway transport, hindering widespread adoption. Therefore, developing a small, strong, lightweight, portable, and easy-to-operate specialized tool suitable for various pipe diameters for quick flange sealing ring replacement is crucial and will significantly improve transport efficiency.

[0025] The main cause of air leakage in railway freight cars is a faulty flange seal. Replacing the flange seal requires specialized tools to create a sufficient gap between the ductwork on both sides of the flange, allowing for quick removal of the damaged seal and installation of a new one. The difficulty in handling this problem lies in the fact that after the flange is removed, the seal is compressed at both ends of the ductwork due to the original installation tension (along the axial direction of the duct). This prevents the seal from being removed and replaced. The specialized device described in this embodiment overcomes this tension by using external force, creating a gap that allows the seal to be freely removed and installed. This achieves the goals of saving time and effort, ensuring safety and reliability, quickly resolving the fault, and improving transportation efficiency. (Refer to the attached instruction manual.) Figure 1 To be continued Figure 7 The following provides a more detailed description of the structure, composition, and use of this device.

[0026] This is a rapid repair tool for flange leaks in railway freight car piping systems. The tool comprises three main functional components: a rack 100, a fixing component 200, and an adjusting component 300. The rack 100 is long and has teeth on one side. The fixing component can be quickly fitted and fixed to one end of the rack, while the adjusting component is quickly fitted and locked in place in the middle of the rack. By operating the adjusting component, the relative distance between the fixing and adjusting components is controlled, effectively creating a gap at the duct opening. The structure of each component is described in detail below.

[0027] The fixing assembly 200 includes a fixing base 210 and a clamp I 220. The fixing base is a block-shaped component with a square blind hole 211 that engages with a rack, inserting the end of the rack into the hole. The fixing base has a three-sided enclosed groove with a dovetail or T-shaped cross-section. Correspondingly, the clamp I has a T-shaped locking head, allowing for quick and easy fixing of the clamp I to the fixing base via insertion. A set screw is provided on the side wall of the insertion groove for temporary fixation of the clamp I.

[0028] Furthermore, clamp I220 preferably has a quick-fixing structure. This clamp adopts an opening and closing structure, and the air duct I can be quickly fixed in the clamp I by tightening bolts, thereby achieving quick fixation of the air duct I.

[0029] The adjusting assembly 300 includes a slider seat 310, clamp II 320, operating lever 330, pawl 340, ratchet 350, check pawl 360, and extension tube 370. The slider seat 310 has a square through hole that passes through a rack. A insertion groove is provided on the back of the slider seat 310. This insertion groove has a three-sided enclosed structure, and the cross-section of the insertion is a dovetail groove or a T-shaped groove. Correspondingly, the clamp II 320 has a corresponding T-shaped locking head, allowing for quick and easy fixing of the clamp II to the fixing seat via insertion.

[0030] Clamp II has the same mechanical structure as Clamp I, so it will not be described in detail again.

[0031] A ratchet mounting groove is provided on the slider seat 310. The ratchet mounting groove is located on the side away from the clamp II. The ratchet mounting groove is located on one side of the slider seat. An operating lever 330, a ratchet 350, and a check pawl 360 are installed in the ratchet mounting groove. The operating lever and the ratchet are coaxially installed in the ratchet mounting groove. The ratchet and the rack form a meshing mechanical engagement relationship. The check pawl is installed in the ratchet mounting groove. Under the action of a torsion spring, the check pawl is attached to the ratchet.

[0032] The aforementioned operating lever has a pawl mounting groove, and a pawl is installed in this groove. Under the action of a torsion spring, the pawl engages with the ratchet. By swinging the operating lever, the ratchet seat can be rotated. Simultaneously, the check pawl prevents the ratchet from reversing.

[0033] The usage instructions for this tool are as follows:

[0034] Assemble the fixing component 200 and adjusting component 300 onto the rack, then fix clamp I to duct I 01 and clamp II to duct II 02. After fixing, use the extension tube to place on the operating rod and swing the operating rod. During this operation, the tool will open the two ducts I and II with sufficient gap. Once the gap meets the requirements, quickly remove the damaged sealing ring 03 and install the new one. After replacement, release the ratchet holding force in the adjusting component and loosen and remove clamps I and II.

[0035] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
