Description

Technical Field

[0001] This utility model relates to the field of traffic line maintenance technology, specifically to a liftable line de-icing device. Background Technology

[0002] In fields such as power transmission and rail transit, the normal operation of lines is crucial for ensuring energy supply and transportation safety. However, in cold winters, lines often accumulate thick layers of ice due to severe weather conditions. Icing significantly increases the weight of the lines, potentially causing them to sag or even break, and can prevent conductors and pantographs from making proper contact with power, severely impacting normal operation and necessitating de-icing. This is especially true for lines above the tracks, which, due to their elevated location and often subject to complex environmental factors, present significant challenges for de-icing. Existing de-icing methods and equipment have many shortcomings in handling de-icing tasks on lines above the tracks. Traditional de-icing tools typically require manual operation at height, which is not only inefficient but also poses significant safety risks. Large de-icing equipment is often limited by site and space constraints, making flexible deployment and operation along the track difficult. Furthermore, the unique structure and layout of lines above the tracks further complicate de-icing work. For example, the limited distance between the line and the track restricts the operating space for de-icing equipment; simultaneously, the height and inclination angle of the lines add to the inconvenience of de-icing operations, increasing the difficulty and complexity of the process.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Reference Figures 1-3 The present invention provides a liftable cable de-icing device for de-icing cables, comprising a base frame 1; a lifting platform 2 that is slidably raised and lowered relative to the base frame 1; and a de-icing component 3 that is slidably raised and lowered relative to the lifting platform 2, the de-icing component 3 being used to slide against the cable.

[0042] In this embodiment, considering the difficulties of de-icing tracks above the railway due to factors such as low efficiency and high risk of manual operation, limitations of large equipment in terms of site and space, and limited operating space caused by the special structure of the track, this solution sets up a base frame 1, a lifting platform 2, and a de-icing component 3. The lifting platform 2 is first adjusted and fixed according to the cable height. The height adjustment of the lifting platform 2 in this solution allows the device to adapt to various icing heights. Furthermore, while the traditional lifting platform 2 has a lifting height of less than 60cm, this solution, through adjustments to the size and fixing holes of the lifting platform 2, can achieve a height adjustment of less than 110cm, better meeting the adaptability requirements of various track heights on the railway. During de-icing, the rapid lifting device of the de-icing component 3 is activated, causing it to move up and down quickly. Upon contact with the ice layer, the striking component rapidly strikes the ice layer, breaking it, and then the scraping component scrapes away the broken ice. Throughout the process, the de-icing component 3 has a fast lifting speed, and the striking and scraping actions are performed continuously. The rapid lifting and lowering movement of the de-icing component 3, combined with the striking and scraping actions, significantly improves the speed and efficiency of de-icing. The striking action effectively breaks up hard ice layers, facilitating subsequent scraping and ensuring more thorough de-icing. The coordinated lifting, striking, and scraping actions reduce repetitive operations during the de-icing process, saving time and manpower. This combined action effectively handles ice layers of varying thickness and hardness, enhancing the device's applicability. The rapid and efficient removal of ice reduces the risk of line faults caused by ice, ensuring the normal operation of the lines.

[0043] Furthermore, the base frame 1 has a ladder section 101 and a base platform section 102. The ladder section 101 and the base platform section 102 are arranged at an angle, and the ladder sections 101 are symmetrically arranged in pairs on the base platform section 102.

[0044] In this embodiment, during use, the base frame 1 is placed in a suitable position. The presence of the ladder 101 facilitates the operator's standing or placement of tools, while the base platform 102 ensures the stable placement of the entire device. The design of the ladder 101 provides the operator with a convenient standing and operating position, facilitating the adjustment and maintenance of the de-icing device. The symmetrically arranged pairs of ladders 101 effectively utilize space without increasing the floor area, making the entire base frame 1 structure more compact. The angled arrangement of the ladder 101 and the base platform 102 increases the contact area between the base frame 1 and the ground, improving the stability of the device during operation and reducing the risk of shaking and tipping. The ladder 101 not only facilitates operation but can also be used for temporary storage of de-icing related tools and equipment, improving work efficiency. When operating on the ladder 101, the operator can better maintain balance and stability, reducing the probability of safety accidents caused by improper operation.

[0045] Furthermore, the lifting platform 2 is connected to the base frame 1 by pins, and the lifting platform 2 can be adjusted and slid on the base frame 1.

[0046] In this embodiment, appropriate pin holes are selected based on the cable height, and pins are inserted into the corresponding pin holes on the base frame 1 and the lifting platform 2 to achieve fixation of the lifting platform 2 on the base frame 1 and height adjustment. By using pin connections and selecting different pin holes, the height adjustment of the lifting platform 2 can be achieved quickly and easily. The cooperation between the pins and pin holes ensures that the lifting platform 2 is accurately and stably positioned after height adjustment, without slippage or displacement. The pin connection provides a reliable connection method, enhancing the structural strength and stability between the lifting platform 2 and the base frame 1. This simple mechanical connection method is low-cost and easy to maintain and replace.

[0047] Furthermore, the ladder 101 has a step 103 and a side 104, and also includes a pair of sliding members 4, with the two sliding members 4 respectively slidingly disposed on the side 104 of the two ladders 101; one end of the first connecting rod 5 and the second connecting rod 6 are respectively hinged to the two sliding members 4; the fixed sleeve rod 7 has a sliding groove 701 in the horizontal direction, and the non-hinged ends of the first connecting rod 5 and the second connecting rod 6 are respectively slidably disposed in the two ends of the sliding groove 701.

[0048] In this embodiment, when the slider 4 slides on the side portion 104, it drives the hinged ends of the first connecting rod 5 and the second connecting rod 6 to move. Simultaneously, the non-hinged ends of the first connecting rod 5 and the second connecting rod 6 slide within the sliding groove 701 of the fixed sleeve rod 7, achieving linkage and position limitation during the sliding of the slider 4. The connection structure of the first connecting rod 5, the second connecting rod 6, and the fixed sleeve rod 7 enhances the strength of the entire ladder portion 101, improving the durability and load-bearing capacity of the device. The design of the fixed sleeve rod 7 and the sliding groove 701 effectively limits the sliding range of the connecting rods, thereby accurately limiting the position of the slider 4 and preventing excessive or insufficient sliding. This flexible sliding and connection structure can adapt to different working scenarios and requirements, maintaining good performance even under different tilt angles or load conditions.

[0049] Furthermore, the fixing sleeve 7 also has a first fixing hole 702, which is oriented horizontally and vertically penetrates the sliding through groove 701. The first connecting rod 5 and the second connecting rod 6 have second fixing holes 703. The first connecting rod 5 and the second connecting rod 6 are configured such that, after sliding, the first fixing hole 702 and the second fixing hole 703 are aligned or unaligned. The fixing plug 8 is configured to be inserted into the first fixing hole 702 and the second fixing hole 703 simultaneously after the first fixing hole 702 and the second fixing hole 703 are aligned.

[0050] In this embodiment, the fixing plug 8 is a pin or bolt. The first connecting rod 5 and the second connecting rod 6 slide within the sliding groove 701. When they slide to a specific position, aligning the first fixing hole 702 with the second fixing hole 703, the fixing plug 8 is simultaneously inserted into both holes 702 and 703 to achieve fixation. To adjust the position, the fixing plug 8 is pulled out, allowing the first connecting rod 5 and the second connecting rod 6 to continue sliding until they are aligned again or the alignment is canceled. By inserting the fixing plug 8 into the aligned fixing holes, the positions of the first connecting rod 5 and the second connecting rod 6 can be firmly locked, ensuring that accidental slippage does not occur during de-icing operations. The positions of the first connecting rod 5 and the second connecting rod 6 can be flexibly adjusted according to actual needs to meet different de-icing conditions and angle requirements. The fixed connecting rod structure is more stable and can withstand the reaction force during the de-icing process, ensuring the stability and safety of the de-icing device.

[0051] Furthermore, the fixed sleeve rod 7 has a vertical first lifting guide groove 704, and also includes a sliding frame 9 which is slidably disposed in the first lifting guide groove 704. The sliding frame 9 has a second lifting guide groove 901, and one end of the de-icing component 3 is slidably disposed in the second lifting guide groove 901.

[0052] In this embodiment, during de-icing operations, the de-icing component 3 slides within the second lifting guide groove 901 of the sliding frame 9, enabling rapid lifting and lowering. Under the constraint and guidance of the guide groove, the de-icing component 3 operates more smoothly during rapid lifting and lowering to remove ice, avoiding disorderly shaking and deviation, thus more effectively striking and removing the ice layer from the cable. The second lifting guide groove 901 ensures the stability of the de-icing component 3 during rapid lifting and lowering, reducing poor de-icing effects or accidental damage to the cable caused by unstable movements. Smooth and rapid striking can more powerfully break the ice layer, improving the efficiency and quality of de-icing. Smooth movement reduces wear on the de-icing component 3 and the entire device, while also reducing potential damage to the cable, extending the service life of the equipment and cable. Stable de-icing action reduces the occurrence of accidents and ensures the safety of operators.

[0053] Furthermore, it also includes a rotation drive 10 mounted on a sliding frame 9; one end of a first crank 11 is mounted on the output end of the rotation drive 10; one end of a first rocker arm 12 is hinged to the other end of the first crank 11, and the other end of the first rocker arm 12 is hinged to one end of the de-icing component 3.

[0054] In this embodiment, the rotary drive 10 is activated, driving the first crank 11 to rotate. The rotation of the first crank 11 is converted into the reciprocating motion of the de-icing component 3 via the first rocker arm 12, enabling the de-icing component 3 to more effectively strike and remove the ice layer. The rotary drive 10 provides power, and the reciprocating motion of the de-icing component 3 is realized through the crank-rocker mechanism, improving the efficiency and effect of de-icing. The movement amplitude and frequency of the de-icing component 3 can be precisely controlled to adapt to different ice conditions and de-icing needs. The reciprocating motion of the de-icing component 3 can generate greater striking force, which helps to break up stubborn ice layers. When dealing with complex icing lines, increasing the rotation speed of the rotary drive 10 allows this device to perform continuous and efficient de-icing actions within a certain range through vibration. The crank-rocker mechanism has a compact structure and does not occupy too much space when mounted on the sliding frame 9, making the overall structure of the device more reasonable. This mechanical transmission method is stable and reliable, reducing the possibility of failure and ensuring the continuity of de-icing operations.

[0055] Furthermore, the end of the de-icing component 3 furthest from the hinge end has a bayonet portion 301, which is used to abut against the cable. The bayonet portion 301 is concave arc-shaped, V-shaped, concave rectangle-shaped, or barb-shaped.

[0056] In this embodiment, during the de-icing process, the de-icing component 3, through reciprocating motion and lifting action, brings the jaw portion 301 into contact with the ice layer on the cable to remove the ice. The special shape of the jaw portion 301 allows for better conformity to the cable's shape, increasing the contact area with the ice layer and improving the de-icing effect. Multiple shapes are available, such as concave arc, V-shape, or concave rectangle. Furthermore, the concave arc and V-shaped de-icing components 3 can also be equipped with barbed structures, enabling the de-icing component 3 to adapt to cables of different diameters and shapes, improving the device's versatility. The rationally designed shape of the jaw portion 301 reduces damage to the cable itself during de-icing, ensuring cable safety. Good fit and a large contact area contribute to faster and more thorough ice removal, improving the efficiency of the de-icing work. The tight contact between the jaw portion 301 and the cable makes the de-icing process more stable, reducing the shaking and displacement of the de-icing component 3, ensuring de-icing quality. The barbed design allows it to hang on the conductor for de-icing, easily handling various complex ice formations. The overall de-icing assembly is normally installed on the lifting platform 2, which also has a position to accommodate construction personnel to stand. In case of complex situations, the device can also be manually operated to carry out de-icing work. The support connecting rod of the de-icing device is an insulated device and can also be operated under power.

[0057] Furthermore, the lifting platform 2 has a stop section 201 and also includes a sliding block 13 that is horizontally slidably disposed on the lifting platform 2; one end of the first connecting rod 14 is hinged to the bottom of the sliding frame 9 and the other end is hinged to the sliding block 13; one end of the first elastic member 15 acts on the stop section 201 and the other end acts on the sliding block 13, providing a force for the sliding block 13 to move away from the stop section 201.

[0058] In this embodiment, during de-icing operations, when the cable height fluctuates, the sliding frame 9 moves up and down accordingly. The movement of the sliding frame 9 drives the sliding block 13 to slide horizontally on the lifting platform 2 via the first connecting rod 14. The elasticity of the first elastic element 15 allows the sliding block 13 to flexibly adjust its position according to changes in cable height, thus adapting to height variations at different points. It can automatically adjust according to fluctuations in cable height, ensuring that the de-icing device maintains good contact with the cable at all times, improving the de-icing effect. It effectively avoids situations where vibration is too strong or too weak in certain areas due to changes in cable height during de-icing, making the de-icing force more uniform. It reduces potential damage to the cable caused by uneven vibration and also lowers the risk of device malfunction due to uneven force. A uniform de-icing force can remove the ice layer more thoroughly, improving the quality and efficiency of de-icing.

[0059] Furthermore, it also includes a traveling wheel 16 rotatably mounted on the base 102, the traveling wheel 16 having a rail groove 1601 for rolling contact with the traveling track.

[0060] In this embodiment, when the device needs to be moved, the track grooves 1601 of the traveling wheels 16 roll and abut against the track, allowing the entire de-icing device to move smoothly and conveniently to the designated location for de-icing operations. The traveling wheels 16 enable the de-icing device to move easily on the track, greatly improving its mobility and work efficiency. The cooperation between the track grooves 1601 and the track ensures the directional accuracy and stability of the device during movement, preventing deviation. This facilitates continuous de-icing operations on long track lines, improving the continuity and coverage of the work.
