Description

Technical Field

[0001] The invention relates to the technical field of railway line maintenance equipment, and in particular to a spraying device for load-bearing cables of an electrified railway contact network. Background Art

[0002] In the operation of electrified railways, catenary cables play a vital role. The cables are exposed to the outdoor environment for a long time, and are eroded by wind, sun, rain and various adverse weather conditions. The protective coating on the surface of the cables that have been installed and put into use for a period of time may be worn, aged, or fall off, which will seriously affect the service life and performance of the cables.

[0003] In order to extend the service life of the catenary cables, they need to be regularly maintained and sprayed. However, due to the special structure and working environment of the catenary cables, the spraying work faces many challenges. The catenary cables need to support the railway power transmission cables, and they will bend at the supporting points, which makes the shape of the spraying area irregular and increases the difficulty of spraying. In addition, there are vertical tension cables between the catenary cables and the power transmission cables. The presence of these tension cables further limits the operating space of the spraying equipment, making it difficult for the spraying equipment in the prior art to approach the part of the catenary cables to be sprayed, and it is impossible to achieve efficient and uniform spraying.

DETAILED DESCRIPTION

[0047] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0049] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0051] Reference Figure 1 to Figure 6An embodiment of the present invention proposes a spraying device for the catenary cables of an electrified railway contact network, which is used for spraying the catenary cables, and includes a body 1; a spraying frame 2 which is movable and swingable relative to the body 1, and the spraying frame 2 has a spraying space 3, and the spraying space 3 is used to accommodate the catenary cables; a first spraying head 4 is swingably set on the body 1 and is located on one side of the spraying space 3.

[0052] In this embodiment, when performing the spraying operation, according to the position and shape of the catenary cable, the spray frame 2 first adjusts the height by lifting and moving so that its spraying space 3 can accurately accommodate the catenary cable. At the same time, the first spray head 4 also swings accordingly to adapt to the position and shape of the catenary cable and spray the catenary cable. The lifting and swinging functions of the spray frame 2 and the swinging of the first spray head 4 can accurately align the part of the catenary cable to be sprayed to ensure the accuracy of the spraying. It can effectively deal with the bending of the catenary cable at the supporting point to ensure comprehensive coverage of the spraying without leaving dead corners. The spraying angle and position can be flexibly adjusted according to different working conditions and the actual state of the catenary cable to improve the spraying efficiency.

[0053] Furthermore, the moving direction of the machine body 1 is defined as horizontal, and it also includes a first swing arm 5, which is swingably set on the machine body 1, and the direction of the swing axis is along the horizontal direction; the second swing arm 6 is swingably set on the first swing arm 5, and the swing axes of the first swing arm 5 and the second swing arm 6 are parallel, and the spray rack 2 is set on the second swing arm 6.

[0054] In this embodiment, when performing the spraying operation, the first swing arm 5 swings on the machine body 1 in the horizontal direction, driving the second swing arm 6 and the spray rack 2 to make a preliminary adjustment of the horizontal position. Then, the second swing arm 6 swings on the first swing arm 5, thereby making a more precise adjustment to the horizontal position of the spray rack 2, so that the spray rack 2 can be accurately aligned with the part of the load-bearing cable to be sprayed. By swinging the first swing arm 5 and the second swing arm 6 in sequence, high-precision adjustment of the horizontal position of the spray rack 2 is achieved, ensuring that the complex shape and position of the load-bearing cable can be accurately aligned. It can flexibly cope with various complex situations such as the bending of the load-bearing cable and the obstruction of the pulling cable, greatly improving the adaptability of the device under different working conditions. Rapid and accurate position adjustment reduces the preparation time before spraying and improves the overall efficiency of the spraying operation.

[0055] Furthermore, it also includes a positioning frame 7, which is arranged on the spraying frame 2, and the positioning frame 7 is located on one side of the spraying space 3; the first positioning member 8 is arranged on the positioning frame 7; the first roller member 9 is rotated and lifted and slid relative to the first positioning member 8, and the rotation axis of the first roller member 9 is in the horizontal direction, and the first roller member 9 is used for rolling abutment with the load-bearing cable.

[0056] In this embodiment, first, the first swing arm 5 and the second swing arm 6 swing to drive the spray rack 2 to adjust its position. Then, the spray rack 2 slides down until the first roller 9 contacts the catenary. During the contact process, since the position of the catenary may have a certain deviation or unevenness, the sliding first roller 9 can be lifted and slid within a certain range, thereby avoiding hard contact with the catenary. When the height or position of the catenary changes, the first roller 9 can slide up and down accordingly, always maintaining rolling contact with the catenary. At the same time, during the spraying operation, the first roller 9 can continue to rotate along its transverse rotation axis to reduce the friction between the catenary and the catenary, and better adapt to the shape and movement of the catenary. Through the cooperation of the swing arm and the sliding action, the first roller 9 is accurately docked with the catenary, ensuring the smooth progress of subsequent work. The sliding setting effectively avoids the damage to the catenary and the device caused by hard contact, and plays a role of buffering and protection. It can flexibly lift and slide according to the actual position and height change of the load-bearing cable, maintain a good contact state, and enhance the adaptability of the device. The continuous rolling contact provides stable support for the load-bearing cable, which helps to achieve uniform and high-quality spraying effect.

[0057] Furthermore, it also includes a second positioning member 10, which is swingably arranged on the first positioning member 8, and the swing axis of the second positioning member 10 is in the horizontal direction; the second roller member 11 is relative to the second positioning member 10 and is arranged to rise, fall, slide and rotate, the rotation axes of the first roller member 9 and the second roller member 11 are parallel, the second roller member 11 is used to roll and abut with the load-bearing cable, and a cable placement space 1101 is formed between the first roller member 9 and the second roller member 11. The second positioning member 10 drives the second roller member 11 to swing to increase the cable placement space 1101, or to reduce the cable placement space 1101.

[0058] In this embodiment, before the spraying operation is performed, the second positioning member 10 drives the second roller member 11 to swing open, enlarging the cable placement space 1101 to facilitate the placement of the catenegro. When the catenegro is placed in place, the second positioning member 10 drives the second roller member 11 to swing closed, reducing the cable placement space 1101, so that the first roller member 9 and the second roller member 11 can be in close contact with the catenegro. During the spraying process, if the position or shape of the catenegro changes, the second roller member 11 adapts by lifting, sliding and rotating. At the same time, the second positioning member 10 can also swing appropriately as needed to adjust the cable placement space 1101 to ensure the stability and good rolling contact of the catenegro. The adjustable cable placement space 1101 facilitates the installation and removal of the catenegro and improves work efficiency. By reducing the cable placement space 1101, the catenegro can be stably clamped to reduce its shaking and displacement during the spraying process. The lifting, sliding, rotation of the second roller member 11 and the swing of the second positioning member 10 can flexibly adapt to various changes of the catenegro and ensure continuous and effective rolling contact. Stable clamping of the load-bearing wire and good contact help achieve more precise spraying, improve the uniformity and quality of the coating. At the same time, the ability to accommodate load-bearing wires of different sizes and shapes increases the versatility of the device.

[0059] Furthermore, it also includes a second spray head 12, which is swingably set on the spray frame 2, and the first spray head 4 and the second spray head 12 are respectively set on both sides of the spray space 3, and the swing axes of the first spray head 4 and the second spray head 12 are both vertical, and the first spray head 4 and the second spray head 12 are configured to swing in opposite directions, and after swinging, they approach or move away from each other, extend into the spray space 3 or move away from the spray space 3.

[0060] In this embodiment, the spray material outlet positions of the first spray head 4 and the second spray head 12 are eccentrically arranged relative to their respective rotation axes, and the first spray head 4 and the second spray head 12 are sprayed from both sides respectively, which can cover the surface of the catenary cable more comprehensively and quickly, thereby improving the spraying efficiency. In addition, during the spraying operation, the first spray head 4 and the second spray head 12 are vertically swung for the relatively straight and stable part of the catenary cable itself. When precise small-scale spraying is required, they are close to each other to form an angle between the spraying directions, and the closer they are, the smaller the angle is, and the closer the distance to the catenary cable is. In this way, concentrated and precise spraying can be performed within a specific small range, and the influence between each other is reduced. The two spray heads are close to each other to form an angle, which can realize precise spraying of a specific straight and stable section of the catenary cable, thereby improving the accuracy and pertinence of the spraying. Concentrated spraying within a small range can make the coating distribution more uniform and thick, and enhance the protective effect. It is suitable for spraying the straight and stable section of the catenary cable, and improves the adaptability of the device to different catenary cable layout states. It can quickly complete high-quality spraying of specific sections, shorten the operation time, and improve overall work efficiency.

[0061] Furthermore, it also includes a first gear 13, which is arranged on the swing axis of the first spray head 4; a second gear 14 is arranged on the swing axis of the second spray head 12, and the first gear 13 and the second gear 14 are meshed; a rotating drive member 15 is arranged on the spray frame 2 to drive the first gear 13 to rotate.

[0062] In this embodiment, when the positions of the first spray head 4 and the second spray head 12 need to be adjusted, the rotating drive member 15 is started to drive the first gear 13 to rotate. Since the first gear 13 and the second gear 14 are meshed, the rotation of the first gear 13 will drive the second gear 14 to rotate in the opposite direction. Thereby, the first spray head 4 and the second spray head 12 can be swung accordingly according to the design requirements to achieve the adjustment of the position and angle. Through the gear meshing method, the synchronous coordination of the swing of the first spray head 4 and the second spray head 12 is achieved to ensure that they can work accurately together. The driving of the first gear 13 by the rotating drive member 15 can achieve precise control of the swing angle and speed of the spray head to meet different spraying requirements. In addition, this mechanical transmission method has high transmission efficiency, stable and reliable operation, and reduces the possibility of failure. Only one rotating drive member 15 needs to be controlled to adjust the two spray heads at the same time, which simplifies the operation process and improves work efficiency.

[0063] Furthermore, the first roller member 9 has a first concave arc portion 901, and the second roller member 11 has a second concave arc portion 1102. Both the first concave arc portion 901 and the second concave arc portion 1102 are used for rolling contact with the load-bearing cable, and the second concave arc portion 1102 has a neck portion 1103. After the second positioning member 10 drives the second roller member 11 to rotate, the load-bearing cable is used to enter or leave the second concave arc portion 1102 from the neck portion 1103.

[0064] In this embodiment, during operation, the first concave arc portion 901 of the first roller member 9 and the second concave arc portion 1102 of the second roller member 11 are in rolling contact with the catenary, providing stable support and guidance. When the catenary needs to be installed or removed, the second positioning member 10 drives the second roller member 11 to rotate, and the catenary can enter or leave from the neck portion 1103 of the second concave arc portion 1102. In addition, during operation, when the cable placement space 1101 is in an open state, due to the design of the neck portion 1103 of the second concave arc portion 1102, the second roller member 11 will not interfere with the tension cable at the bottom of the catenary. Especially when the catenary is located at the position of the bottom hoisting cable, this design can ensure that the second roller member 11 can smoothly contact or separate from the catenary without being hindered by the tension cable. The problem of interference between the second roller member 11 and the tension cable at a specific position is effectively solved, ensuring the normal operation of the device under complex working conditions. It can well cope with the special situation of the catenary at the bottom hoisting cable, expanding the scope of application of the device. It reduces jams and failures caused by component interference, making operations smoother and improving work efficiency.

[0065] Furthermore, it also includes a brush member 16, which is lifted and slidably arranged on the spray frame 2, and the brush member 16 has a brush portion 1601, and the brush portion 1601 is used for slidingly abutting against the load-bearing cable. The brush member 16 also has a groove portion 1602, and the brush portion 1601 is arranged in the groove portion 1602, and the groove portion 1602 is used to accommodate the load-bearing cable.

[0066] In this embodiment, before or during the spraying operation, the brush 16 adjusts its position by lifting and sliding, so that the groove 1602 accommodates the catenary cable, and the brush 1601 slides and abuts against the catenary cable. The brush 16 can move up and down as needed to clean, pretreat or assist in spraying the surface of the catenary cable. Before spraying, the surface of the catenary cable is cleaned and pretreated to remove impurities and old coatings, thereby improving the adhesion of the coating and the quality of spraying. During the spraying process, the sliding abutment of the brush 1601 can help evenly distribute the paint and enhance the spraying effect. The lifting and sliding settings can adapt to catenary cables of different diameters and positions, ensuring effective contact between the brush 1601 and the catenary cable. It integrates the functions of cleaning, pretreatment and auxiliary spraying, reduces the operating steps and improves work efficiency.

[0067] Further, the first positioning member 8 has a first guide groove 801, the second positioning member 10 has a second guide groove 1001, and also includes a first sliding block 17, the first sliding block 17 is slidably set in the first guide groove 801, and the first roller member 9 is rotatably set on the first sliding block 17; the second sliding block 18 is slidably set in the second guide groove 1001, and the second roller member 11 is rotatably set on the second sliding block 18; one end of the first elastic member 19 acts on the first sliding block 17, and the other end acts on the bottom wall of the first guide groove 801, providing a force to move the first sliding block 17 away from the bottom wall of the first guide groove 801; one end of the second elastic member 20 acts on the second sliding block 18, and the other end acts on the top wall of the second guide groove 1001, providing a force to move the second sliding block 18 away from the top wall of the first guide groove 801.

[0068] In this embodiment, since the catena is not in an ideal straight state, there are small fluctuations. In the process of rolling contact with the catena, when the catena has small fluctuations, the first roller 9 and the second roller 11 will be subjected to the force of the catena. At this time, the first sliding block 17 will slide in the first guide groove 801, compressing or stretching the first elastic member 19, and the second sliding block 18 will slide in the second guide groove 1001, compressing or stretching the second elastic member 20. The elastic force of the elastic member will react on the sliding block, so that the first roller 9 and the second roller 11 can continue to maintain pressure rolling contact with the catena. It can effectively deal with the small fluctuations of the catena, ensure that the roller always maintains good contact with the catena, and improve the adaptability of the device. Through the cooperation of the elastic member and the sliding block, the contact pressure between the roller and the catena is kept stable, ensuring the reliability of the work. Continuous and stable contact helps to achieve a uniform and high-quality spraying effect and enhance the protective performance of the catena. Avoid uneven local spraying or leakage due to poor contact, and reduce damage to the catena.

[0069] Furthermore, it also includes a third elastic member 21, one end of the third elastic member 21 acts on the spray frame 2, and the other end acts on the brush member 16 to provide a force for the brush member 16 to slide down; one end of the first connecting rod 22 is hinged to the brush member 16, and the other end is hinged to the second positioning member 10. The first connecting rod 22 is configured so that after the brush member 16 rises and falls and slides relative to the spray frame 2, the second positioning member 10 is driven to swing through the first connecting rod 22.

[0070] In this embodiment, first, by controlling the height of the spraying frame 2, the brush member 16 is brought into contact with the load-bearing cable, and then the brush member 16 is further squeezed and pushed until the first roller member 9 also comes into contact with the load-bearing cable. Under the action of the third elastic member 21, the brush member 16 comes into closer contact with the load-bearing cable. At the same time, when the brush member 16 does not come into contact with the load-bearing cable, the second positioning member 10 drives the second roller member 11 to be in an outward swing state through the connection of the first connecting rod 22, and the cable placement space 1101 is opened. This is the first non-contact working state, which belongs to natural reset.

[0071] The second working state is that when the straight section encounters the pulling section of the catenary cable and the catenary cable is in a downward bending state, the pressure between the brush 16 and the catenary cable is reduced until they are separated, and the brush 16 slides downward relative to the spray frame 2, driving the cable placement space 1101 to open, and the second roller 11 avoids the pulling cable. In this section, the angle between the first spray head 4 and the second spray head 12 increases and moves away, and the catenary cable is sprayed in a wider range by manually controlling the first swing arm 5 and the second swing arm 6, taking into account the synchronous spraying of the catenary cable and the pulling cable. After returning from the concave section of the catenary cable to the straight section, the brush 16 contacts the catenary cable again, and then closes the cable placement space 1101, and continues the automatic positioning spraying work.

[0072] This solution can cope with different shapes and position changes of the catenary cables, including straight sections, downward curved sections and pulling sections, which improves the versatility and adaptability of the device. Through the action of the brush 16 and the roller and the adjustment of the cable placement space 1101, precise contact with the catenary cables and effective avoidance of obstacles are achieved, ensuring the smooth progress of the spraying work. The position and angle of the spray head can be reasonably adjusted under different working conditions to achieve more comprehensive and uniform spraying, thereby improving the quality of the protective coating of the catenary cables and pulling cables. The combination of automatic positioning spraying and manual control not only ensures work efficiency, but also enables flexible processing under complex working conditions, thereby improving the reliability of the device.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
