Description

Technical Field

[0001] This utility model relates to the field of maintenance device technology, specifically a portable railway line maintenance device. Background Technology

[0002] A railway line is a specific path for trains to travel, consisting of rails, sleepers, ballast, etc. Railway lines are the foundation of railway transportation, bearing the weight of trains and their cargo, and guiding trains to travel in a predetermined direction. Railway line maintenance devices are indispensable tools in railway maintenance work. Rail turners are a relatively common type of railway line maintenance device, but existing maintenance devices still have certain defects in use.

[0003] There are many types of railway line maintenance devices in the existing technology. The rail flipper is a commonly used railway maintenance tool. The rail flipper is easy to carry. The rail flipper is mainly used to change the direction of the track, adjust the gauge, and replace the track in railway maintenance work. By using the rail flipper, maintenance personnel can operate and replace the track more conveniently, thereby improving work efficiency and safety. The traditional rail flipper has a relatively simple overall structure. The rail flipper is mainly composed of a handle and a curved clamp mouth. Because the outer surface of the handle is relatively smooth, it is easy for the operator to slip when holding the handle, resulting in low railway line maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a portable railway line maintenance device to solve the problem of hand slippage that currently available maintenance devices on the market are prone to during use, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable railway line maintenance device, comprising: a handle body and a curved pliers mouth, wherein the end of the handle body is connected to the curved pliers mouth, a slot is provided on the outer side of the handle body, an anti-slip sleeve is slidably connected to the outer side of the handle body, a connecting shaft is connected inside the anti-slip sleeve, a locking block is rotatably connected to the outer side of the connecting shaft, a tension spring is connected between the locking block and the anti-slip sleeve, a rotating plate is movably connected to the ends of the two locking blocks through a rotating shaft, a pressing block is movably connected between the two rotating plates through a rotating shaft, a magnet is installed inside the anti-slip sleeve, and a baffle is magnetically attracted to the outer side of the two magnets.

[0006] Preferably, the baffles are arranged in two sets symmetrically about the center of the handle body.

[0007] Preferably, the pressing block is T-shaped.

[0008] Preferably, a connecting ring is welded to the outer side of the handle body away from the curved pliers mouth, and an insertion interface is provided at the top of the connecting ring, with a plastic limiting post connected to the inner wall of the insertion interface.

[0009] Preferably, a protective sleeve is provided on the outer side of the end of the handle body near the connecting ring, and a fixing ring is connected to the outer side of the protective sleeve.

[0010] Preferably, a plug rod is connected to the bottom of the fixing ring, and a locking rod is connected to the outside of the plug rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This portable railway line maintenance device can press the ends of two sets of pressing blocks inside the anti-slip sleeve closer to each other. When one set of pressing blocks moves, it can drive two sets of rotating plates to move through two sets of rotating shafts. When the two sets of rotating plates move, they can drive one end of two sets of locking blocks to move closer to each other through the rotating shafts. When the plug rod and locking rod move to the maximum position, the plastic limiting post in the squeezed state can be reset. At this time, the two sets of plastic limiting posts can limit the locking rod, thereby making the protective sleeve fit on the end of the handle body and preventing it from falling off. The protective sleeve can protect the end of the handle body, thereby improving the safety of the maintenance device during use.

[0012] 1. Railway line maintenance devices can improve the efficiency and convenience of railway line maintenance. Traditional rail tippers are prone to slippage at the handle, leading to low maintenance efficiency. This device allows for pressing the ends of two sets of pressing blocks inside the anti-slip sleeve closer together. When one set of pressing blocks moves, it drives two sets of rotating plates via two sets of shafts. The movement of these rotating plates, in turn, drives one end of two sets of locking blocks closer together via the shafts. When the tension spring is stretched to a specified degree, the other end of the locking block can rotate from inside the slot into the anti-slip sleeve. At this point, the anti-slip sleeve can be pushed. When the end of the locking block near the handle body moves to the outside of a designated set of slots, the two sets of pressing blocks can be released. At this time, the tension spring can be reset, so that the end of the locking block near the handle body can engage with the inside of the designated set of slots, thereby adjusting the position of the anti-slip sleeve. The baffle is then placed inside the anti-slip sleeve, so that the baffle can be magnetically attracted to the magnet. The anti-slip sleeve can prevent the operator from slipping their hand when using the rail flipper, and the position of the anti-slip sleeve can be adjusted according to the operator's usage habits.

[0013] 2. The overall structure of the railway line maintenance device is relatively simple. However, if the handle is not operated properly during use, workers and nearby personnel may be poked by the end of the handle, posing a safety hazard. To address this, a protective sleeve can be fitted over the outside of the handle's end. Then, the insertion rod and locking rod at the bottom of the fixing ring can be placed into the corresponding insertion interfaces inside the connecting ring. As the protective sleeve rotates, it drives the fixing ring and insertion rod to rotate as well. When the locking rod moves to the designated position, its end can compress the ends of the two sets of plastic limiting posts, causing them to deform. When the insertion rod and locking rod move to their maximum position, the compressed plastic limiting posts reset. At this point, the two sets of plastic limiting posts limit the locking rod, thus securing the protective sleeve to the handle's end and preventing it from falling off. The protective sleeve protects the handle's end, improving the safety of the maintenance device during use. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-3 It is understood that this utility model provides a technical solution: a portable railway line maintenance device, including: a handle body 1 and a curved pliers mouth 2. The end of the handle body 1 is connected to the curved pliers mouth 2. A slot 3 is opened on the outer side of the handle body 1. An anti-slip sleeve 4 is slidably connected to the outer side of the handle body 1. A connecting shaft 5 is connected inside the anti-slip sleeve 4. A locking block 6 is rotatably connected to the outer side of the connecting shaft 5. A tension spring 7 is connected between the locking block 6 and the anti-slip sleeve 4. The ends of the two locking blocks 6 are movably connected to a rotating plate 8 through a rotating shaft. A pressing block 9 is movably connected between the two rotating plates 8 through a rotating shaft. A magnet block 10 is installed inside the anti-slip sleeve 4. A baffle 11 is magnetically attracted to the outer side of the two magnet blocks 10. Two sets of baffles 11 are symmetrically arranged about the center of the handle body 1. The pressing block 9 is T-shaped.

[0023] In practical implementation, railway line maintenance devices can improve the efficiency and convenience of railway line maintenance. Traditional rail turners are prone to slippage at the handle body 1 during use, leading to low railway line maintenance efficiency. Before using the rail turner, the ends of the two sets of pressing blocks 9 inside the anti-slip sleeve 4 can be pressed close together. When one set of pressing blocks 9 moves, it drives two sets of rotating plates 8 to move via two sets of rotating shafts. When the two sets of rotating plates 8 move, they drive one end of two sets of locking blocks 6 to move close together via rotating shafts. When the locking blocks 6 move, they can rotate via connecting shaft 5, and when the locking blocks 6 rotate, they can stretch the tension spring 7. When the tension spring 7 is stretched to a specified degree, the other end of the locking block 6... The end can be rotated from inside the slot 3 to inside the anti-slip sleeve 4. At this time, the anti-slip sleeve 4 can be pushed. When the anti-slip sleeve 4 moves, it can slide along the outside of the handle body 1. When the end of the locking block 6 near the handle body 1 moves to the outside of a designated set of slots 3, the two sets of pressing blocks 9 can be released. At this time, the tension spring 7 can be reset, so that the end of the locking block 6 near the handle body 1 can be engaged inside the designated set of slots 3, thereby adjusting the position of the anti-slip sleeve 4. The baffle 11 is placed inside the anti-slip sleeve 4. The baffle 11 is made of iron, so that the baffle 11 can be magnetically attracted to the magnet block 10, thereby blocking the pressing block 9 and making it less likely for the pressing block 9 to be accidentally touched.

[0024] See Figures 1-3It can be seen that the anti-slip sleeve 4 can prevent the operator from slipping their hand when using the rail flipper, and the position of the anti-slip sleeve 4 can be adjusted according to the operator's usage habits.

[0025] See Figure 1 , Figure 4 , Figure 5 and Figure 6 It can be seen that a connecting ring 12 is welded to the outer side of the handle body 1 away from the curved pliers mouth 2. The top of the connecting ring 12 is provided with an insertion interface 13. A plastic limiting post 14 is connected to the inner wall of the insertion interface 13. A protective sleeve 15 is provided on the outer side of the end of the handle body 1 near the connecting ring 12. A fixing ring 16 is connected to the outer side of the protective sleeve 15. A plug rod 17 is connected to the bottom of the fixing ring 16. A locking rod 18 is connected to the outer side of the plug rod 17. The ends of the locking rod 18 and the plastic limiting post 14 are both arc-shaped.

[0026] In practical implementation, the overall structure of the railway line maintenance device is relatively simple. The end of the handle body 1 away from the curved clamp mouth 2 is usually conical, which can be inserted and placed on the ground. However, if the handle body 1 is not operated properly when the rail turner is in use, the staff and nearby personnel are easily poked by the end of the handle body 1, which poses a certain safety hazard when the maintenance device is in use. The protective sleeve 15 can be first put on the outside of the end of the handle body 1, so that the fixing ring 16 on the protective sleeve 15 can be moved above the connecting ring 12. At this time, the insertion rod 17 and the locking rod 18 at the bottom of the fixing ring 16 can be placed into the corresponding insertion interface 13 inside the connecting ring 12. Then, the protective sleeve 15 is rotated clockwise. When the protective sleeve 15 rotates, it can drive the fixing ring 16 and the insertion rod 17 to rotate. When the insertion rod 17 moves, it can drive the locking rod 18 to move along the inner wall of the insertion interface 13. When the locking rod 18 moves to the designated position, its end can squeeze the ends of the two sets of plastic limiting posts 14, so that the plastic limiting posts 14 can be squeezed and deformed.

[0027] See Figure 1 , Figure 4 , Figure 5 and Figure 6 It can be seen that when the plug rod 17 and the locking rod 18 move to the maximum position, the plastic limiting post 14 in the squeezed state can be reset. At this time, the two sets of plastic limiting posts 14 can limit the locking rod 18, so that the protective sleeve 15 is fitted onto the end of the handle body 1 and is not easy to fall off. The protective sleeve 15 can protect the end of the handle body 1, thereby improving the safety of the maintenance device during use.

[0028] In summary, when using this portable railway line maintenance device, the ends of the two sets of pressing blocks 9 inside the anti-slip sleeve 4 can be pressed closer to each other. When one set of pressing blocks 9 moves, it can drive the two sets of rotating plates 8 to move through the two sets of rotating shafts. When the two sets of rotating plates 8 move, they can drive the ends of the two sets of locking blocks 6 to move closer to each other through the rotating shafts. The anti-slip sleeve 4 can prevent the operator from slipping when using the rail tipper, and the position of the anti-slip sleeve 4 can be adjusted according to the operator's usage habits. The protective sleeve 15 can protect the end of the handle body 1, thereby improving the safety of the maintenance device during use.
