Description

Technical Field

[0001] This utility model relates to the field of railway contact wire de-icing technology, specifically to a railway contact wire de-icing device. Background Technology

[0002] Traditional tools for de-icing contact lines include insulated ice-breaking rods and wooden ice-breaking rods. These tools remove ice by striking the contact line to generate vibration. Using insulated ice-breaking rods requires wearing insulated boots and gloves. These rods are quite long, typically up to six meters, requiring personnel to hold them high and walk forward while striking. This limited physical strength results in short de-icing sections and incomplete de-icing. Using wooden ice-breaking rods requires continuous striking of the contact line, which can also lead to incomplete de-icing in areas with thick ice. Repeatedly striking the same point can damage the contact line if the force is not properly controlled.

[0003] Therefore, there is a need to design a lightweight, flexible, thorough de-icing tool that does not damage the contact wire. Utility Model Content

[0004] The purpose of this invention is to provide a railway contact line de-icing device. It consists of two relatively rotatable semi-circular steel pipes, with a first arc-shaped buckle, a second arc-shaped buckle, and a fixing component between them. After rotating and clamping the two steel pipes onto the contact line requiring de-icing, the first and second arc-shaped buckles are locked together by the fixing component, thus securing the two semi-circular steel pipes to the outside of the contact line. Then, the worker at height grips the handles firmly with both hands and pushes in the same direction, using the fixing pins to easily break up the ice covering the contact line, achieving rapid de-icing. This not only significantly reduces damage to the contact line but also reduces the physical exertion of the user. Compared to existing tools, this tool is small, easy to use and carry, and requires less technical skill from the user, greatly meeting the needs of high-altitude operations and addressing the aforementioned shortcomings of existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a railway contact wire de-icing device, comprising:

[0006] The de-icing device body includes two symmetrically arranged semi-circular steel pipes. One of the steel pipes has a first arc-shaped buckle symmetrically fixed at both ends on its outer side, and the other steel pipe has a second arc-shaped buckle symmetrically fixed at both ends on its outer side. The top ends of the first arc-shaped buckle and the second arc-shaped buckle are rotatably connected by a pivot, and a fixing component is provided between the bottom ends of the first arc-shaped buckle and the second arc-shaped buckle.

[0007] A connecting post is fixed to the middle of the outer side of each of the two steel pipes, and a handle can be detachably connected to one end of each connecting post relative to the steel pipe.

[0008] Preferably, the fixing component includes a groove at the bottom end of the first arc-shaped buckle, a screw is rotatably connected to the inside of the groove via a rotating shaft, and a buckle knob is threadedly connected to the bottom end of the screw. The bottom end of the second arc-shaped buckle has a channel that matches the screw, and the top end of the channel has a circular insertion hole that matches the buckle knob.

[0009] Preferably, the end of the handle near the connecting post is provided with a threaded head, and the end of the connecting post is provided with a threaded groove that matches the threaded head.

[0010] Preferably, the outer wall of the handle is provided with anti-slip texture, and the end of the handle is provided with a rounded chamfer.

[0011] Preferably, a plurality of fixing nails are symmetrically arranged at one end of each of the two steel pipes.

[0012] Preferably, one of the steel pipes is provided with a connecting frame at one end relative to the fixing nail, a support plate is fixed at one end of the connecting frame, a fixing knob is connected to the middle of the side wall of the support plate by a thread, and an arc-shaped clamping plate is movably connected to one end of the fixing knob and located inside the support plate by a bearing, and multiple slices are provided on the inner side of the arc-shaped clamping plate.

[0013] Preferably, the support plate has guide posts symmetrically extending through both ends, and one end of the guide post is fixedly connected to the arc-shaped clamping plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] By setting two semi-circular steel pipes that can rotate relative to each other, and with a first arc-shaped buckle, a second arc-shaped buckle, and a fixing component between the two steel pipes, after the two steel pipes are rotated and clamped on the contact line that needs to be de-iced, the first arc-shaped buckle and the second arc-shaped buckle can be locked by the fixing component, thus securing the two semi-circular steel pipes to the outside of the contact line. Then, the high-altitude worker can firmly grasp the handle with both hands and push in the same direction, and with the help of the fixing nail, the ice covering the outside of the contact line can be easily broken up to achieve rapid de-icing. This not only greatly reduces damage to the contact line, but also reduces the physical exertion of the user. Compared with existing tools, this tool is small in size, easy to use and carry, and has low technical requirements for the user, which greatly meets the needs of high-altitude operations.

[0016] In addition, by setting threaded heads and threaded grooves, the handle can be quickly attached and detached from the steel pipe, and by separating the handle from the steel pipe, it is more convenient to store and carry the device.

[0017] By setting up a connecting frame, a fixed knob, an arc-shaped clamping plate, and multiple sets of blades, when the ice is thick and difficult to break up by impact, the arc-shaped clamping plate can be controlled to drive multiple sets of blades tangentially towards the ice, so that the blades cut into the surface of the ice layer or get stuck in the gaps in the ice layer. Then, by using the handle to drive the steel pipe and blades to rotate, the hard ice can be quickly broken up by the twisting action of the blades on the ice, thereby further realizing the de-icing function, ensuring thorough de-icing, and greatly improving the effectiveness of the device.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1-5 The railway contact wire de-icing device shown includes:

[0028] The de-icing device body includes two symmetrically arranged semi-circular steel pipes 1. One steel pipe 1 has a first arc-shaped buckle 4 symmetrically fixed at both ends of its outer side, and the other steel pipe 1 has a second arc-shaped buckle 8 symmetrically fixed at both ends of its outer side. The top ends of the first arc-shaped buckle 4 and the second arc-shaped buckle 8 are rotatably connected by a pivot, and a fixing component is provided between the bottom ends of the first arc-shaped buckle 4 and the second arc-shaped buckle 8.

[0029] The fixing component includes a groove 5 at the bottom of the first arc-shaped buckle 4, a screw 6 is rotatably connected inside the groove 5 via a rotating shaft, a buckle knob 7 is threadedly connected to the bottom of the screw 6, and a channel 10 matching the screw 6 is opened at the bottom of the second arc-shaped buckle 8, and a circular insertion hole 9 matching the buckle knob 7 is provided at the top of the channel 10.

[0030] Multiple fixing nails 11 are symmetrically arranged at one end of each of the two steel pipes 1.

[0031] A connecting post 2 is fixed to the middle of the outer side of each of the two steel pipes 1, and a handle 3 can be detachably connected to one end of each connecting post 2 relative to the steel pipe 1.

[0032] The outer wall of the handle 3 is provided with anti-slip texture, and the end of the handle 3 is provided with a smooth chamfer.

[0033] The handle 3 can be made of insulating material, and the anti-slip texture can enhance the anti-slip performance when gripping, while the rounded chamfer can prevent scratches to the operator.

[0034] The handle 3 has a threaded head 13 at one end near the connecting post 2, and the connecting post 2 has a threaded groove 12 that matches the threaded head 13 at one end. By setting the threaded head 13 and the threaded groove 12, the handle 3 can be quickly attached and detached from the steel pipe 1 when the threaded head 13 and the threaded groove 12 are screwed together. Furthermore, by separating the handle 3 from the steel pipe 1, it is more convenient to store and carry the device.

[0035] Through the above technical solution:

[0036] When in use, by holding the handles 3 on both sides with both hands, the two steel pipes 1 can be rotated and separated by the relative rotation of the first arc-shaped buckle 4 and the second arc-shaped buckle 8. Then, the two steel pipes 1 can be brought close to the contact line that needs to be de-iced and clamped together. Then, the buckle knob 7 at the bottom of the first arc-shaped buckle 4 can be pulled to rotate, so that the buckle knob 7 drives the screw 6 to rotate and pass through the channel 10 into the circular insertion hole 9. Then, the buckle knob 7 on the screw 6 can be turned to make the end of the buckle knob 7 tightly inserted into the circular insertion hole 9, thereby locking the first arc-shaped buckle 4 and the second arc-shaped buckle 8, thus securing the two semi-circular steel pipes 1 to the outside of the contact line. Then, the high-altitude worker can hold the handles 3 with both hands and push in the same direction, and with the help of the fixing nails 11 at the end, the ice covering the outside of the contact line can be easily broken up to achieve rapid de-icing. This not only greatly reduces the damage to the contact line, but also reduces the physical exertion of the user, and the effect is good.

[0037] Furthermore, after de-icing is completed, or if other equipment blocks the advance of the de-icing tool, the two steel pipes 1 can be quickly unlocked by turning the buckle knob 7 in the opposite direction, thereby separating them from the contact line.

[0038] Compared to existing tools, this tool is small in size, easy to use, requires less technical skill from the user, and can be made of lightweight and sufficiently rigid materials, making it easy for users to carry.

[0039] In one specific embodiment of this utility model, a connecting frame 14 is provided at one end of a steel pipe 1 relative to a fixing nail 11. A support plate 15 is fixed at one end of the connecting frame 14. A fixing knob 16 is threadedly connected to the middle of the side wall of the support plate 15. An arc-shaped clamping plate 17 is movably connected to one end of the fixing knob 16 and located inside the support plate 15 via a bearing. Multiple slices 18 are provided on the inner side of the arc-shaped clamping plate 17.

[0040] Guide posts 19 are symmetrically inserted through both ends of the support plate 15, and one end of the guide post 19 is fixedly connected to the arc-shaped clamping plate 17. With the support and guidance of the guide posts 19, the arc-shaped clamping plate 17 can be ensured to move stably along a straight line.

[0041] When the ice is thick and difficult to break up by impact, after the steel pipe 1 is fixed to the contact line, it can be moved to bring the connecting frame 14 closer to the ice. By turning the fixing knob 16, the fixing knob 16 drives the arc-shaped clamping plate 17 to move towards the ice. Then, the arc-shaped clamping plate 17 drives multiple sets of slices 18 to cut into the ice, so that the slices 18 cut into the surface of the ice layer or get stuck in the gaps in the ice layer. Then, by gripping the handle 3, the steel pipe 1 is rotated, which drives the multiple sets of slices 18 to rotate. Under the twisting of the slices 18 against the ice, the hard ice can be quickly broken up, thereby further realizing the de-icing function, ensuring thorough de-icing, and greatly improving the use effect of the device.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
