Description
Technical Field
[0001] The utility model belongs to the technical field of railway contact network load-bearing cable laying-out, and in particular relates to a railway contact network load-bearing cable laying-out pulley device. Background Art
[0002] The laying out of the catenary cables of the railway contact network is an important construction project in the construction of the contact network. In the traditional curved section (the pillar is located on the inner side of the curve), the laying out device of the catenary cables is prone to eccentric wear, jamming, or the operators are unable to ease the cables into the flat wrist arm, which poses the risk of damaging the cables and jamming the cables, affecting the construction progress and quality. Once the cables are damaged, the "skylight", manpower and material resources are wasted, the entire cable is abandoned, and the economic loss is serious; the laying out of the traditional straight section requires the catenary cables to be turned from the bottom of the wrist arm to the catenary cable groove seat, and the wrist arm with the inclined cable needs to remove the inclined cable before the catenary cables are laid, which is inefficient. When constructing the existing line, the distance between the existing cable and the new line is large, which makes it inconvenient to compare the sag. In addition, the catenary cables cannot be fully eased and the ladder car group cannot carry out the hanging string adjustment operation and many other disadvantages. Utility Model Content
[0003] In order to solve the above-mentioned problems in the prior art, namely, the conventional curved section catenary cable pay-out device is prone to uneven wear and jamming of the cable, or the operator is unable to slowly put the cable into the flat wrist arm, and the conventional straight section pay-out requires the catenary cable to be flipped from the bottom of the wrist arm into the catenary cable groove seat, and the wrist arm with the oblique cable needs to remove the oblique cable before releasing the catenary cable, which is inefficient, the utility model provides a railway contact network catenary cable pay-out pulley device.
[0004] The present application provides a railway overhead contact network load-bearing cable pay-out pulley device, which adopts the following technical solution:
[0005] A railway overhead contact network load-bearing cable pay-off pulley device, comprising a curve section pay-off assembly and a straight section pay-off assembly;
[0006] The curved section pay-off assembly comprises a support rod connected to the flat wrist arm and arranged obliquely, a lever hoist hung on the end of the support rod, and a common hanging electric pay-off pulley connected to the hook chain of the lever hoist;
[0007] The straight section pay-off assembly comprises a support pulley detachably connected to the flat wrist arm.
[0008] By adopting the above technical solution, when the catenary cable is released in the curved section, the hand-operated hoist chain and the commonly used hanging electric wire-release pulley are in a vertical state, and the catenary cable moves in the pulley. When dropping anchor, the catenary cable will generate a pulling force toward the inside of the curve, so the pulley will swing toward the inside of the curve with the catenary cable. Since the catenary cable is always in the center of the pulley groove, the catenary cable will not be stuck or damaged. In addition, after dropping anchor, the catenary cable can be slowly moved into the catenary cable seat groove by releasing the hand-operated hoist, saving manpower and improving work efficiency.

At the same time, there is no need to flip the catenary cable from the bottom of the flat wrist arm to the catenary cable seat groove, saving manpower and improving work efficiency. In the construction of existing lines, due to the long distance between the new and old catenary cables in the traditional wire-release method, it is impossible to compare the sag of the new and old cables. In the straight section, the use of the load-bearing cable pay-out device makes the distance between the new and old load-bearing cables closer, which is convenient for operators to observe and compare the cable sag.

[0025] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings.
[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0027] The utility model provides a railway contact network load-bearing cable pay-off pulley device, referring to Figure 1 , Figure 2 The railway overhead contact network load-bearing cable pay-off pulley device comprises a curve section pay-off assembly 1 and a straight section pay-off assembly 2.
[0028] The railway overhead contact network catenary cable pay-off pulley device is installed on the railway overhead contact network system 3. The railway overhead contact network system 3 mainly includes columns 31 arranged on both sides of the railway. A horizontally arranged flat arm 32 is installed on the column 31. The flat arm 32 is rod-shaped as a whole. An oblique arm 33 is installed between the flat arm 32 and the column 31. One end of the oblique arm 33 is fixedly connected to the column 31, and the other end is fixedly connected to the flat arm 32 in the middle of the flat arm 32 to support the flat arm 32. A cable seat 34 is installed on the flat arm 32. The cable seat 34 is used to receive and support the catenary placed on the column 31.
[0029] Reference Figure 3 The curved section pay-off assembly 1 comprises a support rod 11, which is arranged obliquely. Two cross hoops 12 are installed on the support rod 11. One cross hoop 12 is arranged at the end of the support rod 11 and connects the support rod 11 with the oblique wrist arm 33. The other cross hoop 12 is arranged in the middle of the support rod 11 and connects the support plate with the flat wrist arm 32. The support rod 11 is arranged at about 45 degrees to the horizontal plane. A horseshoe connecting ring 13 is installed on the other end of the support rod 11, and the horseshoe connecting ring 13 is hinged to the end of the support rod 11. A hand-operated hoist 14 is hung on the horseshoe connecting ring 13, and the horseshoe connecting ring 13 is connected to the main body hook of the hand-operated hoist 14. The hook chain of the hand-operated hoist 14 is hooked to the commonly used hanging electric pay-off pulley 15. When releasing the wire, the load-bearing wire is placed in the groove of the commonly used hanging electric wire-releasing pulley 15, and the vertical height of the load-bearing wire shall not be lower than the flat wrist arm 32. After the load-bearing wire is anchored, the load-bearing wire is released into the groove of the load-bearing wire seat 34 by releasing the hand-operated hoist 14, and the load-bearing wire seat 34 pressure plate is tightened to fix the wire, completing the wire-releasing process. After the wire-releasing is completed, the curve section wire-releasing assembly 1 is removed. When all the hanging points are fully relaxed, the wire-releasing process is completed.
[0030] Among them, anchoring the catenary means tightening the tail end of the catenary to fix it on the column 31. Moreover, in the process of installing the catenary using the curved section pay-off assembly 1 in the curved section, there is an arc between the two columns 31. As the two ends of the catenary are tightened, the catenary takes the commonly used hanging electric pay-off pulley 15 and deflects with the end of the support rod 11 as the axis, so that during the catenary pay-off process, it is always located in the center of the groove of the commonly used hanging electric pay-off pulley 15, thereby reducing the jamming phenomenon between the catenary and the wheel during the pay-off process and reducing the wear of the catenary when it moves. After anchoring, the catenary can be closer to the catenary seat 34, and the catenary can be arranged in the groove of the catenary seat 34 by directly releasing the hand hoist 14.
[0031] Reference Figure 4The straight section pay-off assembly 2 includes a wrist hoop 21 installed on a flat wrist 32, the wrist hoop 21 is connected to the flat wrist 32 by a hoop connection, a support pulley 22 is installed on the upper side of the wrist hoop 21, a U-shaped plate 23 is arranged between the support pulley 22 and the wrist hoop 21, and the U-shaped plate 23 is connected to the wrist hoop 21 by bolts, the bolts not only connect the U-shaped plate 23 to the wrist hoop 21, but also can be used as bolt shafts to make the U-shaped plate 23 rotate horizontally on the wrist hoop 21 around the bolt shaft. A rotating shaft 24 is penetrated on the U-shaped plate 23, and both ends of the rotating shaft 24 are fixedly connected to the U-shaped plate 23, and the support pulley 22 is sleeved on the rotating shaft 24, so that the support pulley 22 is arranged in the U-shaped plate 23. The load-bearing cable is arranged and installed on the support pulley 22. The installation position of the straight section pay-off assembly 2 is close to the load-bearing cable seat 34.
[0032] Among them, the U-shaped plate 23 rotates horizontally around the bolt axis on the wrist clamp 21, so that during the process of the load-bearing cable being released, when the load-bearing cable has a deflection angle along the line (railway) direction, the U-shaped plate 23 can rotate along the line deflection, so that the line is always located in the center of the pulley groove to prevent the line from being stuck or damaged.
[0033] When laying out the line, place the load-bearing cable in the groove of the support pulley 22. After the load-bearing cable is anchored, the load-bearing cable is slowed down to the groove of the load-bearing cable seat 34. After the slowing down is completed, the straight section pay-out assembly 2 is removed. The straight section pay-out assembly 2 can be directly installed and paid out, eliminating the steps of fixing the flat wrist arm 32 and the positioning tube with iron wire, removing the inclined wire, restoring the inclined wire, and removing the iron wire. At the same time, there is no need to flip the load-bearing cable from the bottom of the flat wrist arm 32 to the groove of the load-bearing cable seat 34, which saves manpower and improves work efficiency. During the construction of existing lines, due to the long distance between the new and old load-bearing cables in the traditional pay-out method, it is impossible to compare the sag of the new and old lines. However, the use of the straight section load-bearing cable pay-out device makes the distance between the new and old load-bearing cables closer, which is convenient for operators to observe and compare the sag of the lines.
[0034] Reference Figure 4 , Figure 5, an anti-offline buckle 25 is also installed on the U-shaped plate 23, and the anti-offline buckle 25 includes a cover plate 251, and the cover plate 251 covers the upper side of the U-shaped plate 23, and a seesaw 252 is fixedly connected to one side of the cover plate 251, and the seesaw 252 is in contact with the outer surface of the U-shaped plate 23. A torsion spring 253 is installed between the cover plate 251 and the seesaw 252, and the torsion spring 253 is installed on the U-shaped plate 23, so that the anti-offline buckle 25 and the U-shaped plate 23 are connected together through the torsion spring 253. Among them, when the cover plate 251 is covered on the upper side of the U-shaped plate 23, one side of the cover plate 251 is suspended, and the seesaw 252 is in contact with the outer surface of the U-shaped plate 23. When the cover plate 251 is subjected to a force from bottom to top, the cover plate 251 tends to tilt upward. After the tilting tendency of the cover plate 251 is transmitted to the seesaw 252, the seesaw 252 tends to move toward the U-shaped plate 23. Before moving, the seesaw 252 contacts the surface of the U-shaped plate 23, so that the U-shaped plate 23 limits the movement of the seesaw 252, thereby limiting the tilting of the cover plate 251, and further, when the catenary placed on the lower side of the cover plate 251 bounces up, the cover plate 251 can limit the lifting of the catenary. When the cover plate 251 is subjected to a force from top to bottom, the cover plate 251 moves downward, and the seesaw 252 tilts to the side away from the U-shaped plate 23, thereby opening the upper side of the U-shaped plate 23 and taking the catenary out of the U-shaped plate 23. The cover plate 251 and the seesaw 252 are integrally formed.
[0035] In addition, by providing the torsion spring 253 , when the cover plate 251 moves downward, the torsion spring 253 applies a reverse force to the cover plate 251 , thereby controlling the cover plate 251 to return to its original position.
[0036] The term "comprise" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that includes a list of elements includes not only those elements but also other elements not expressly listed, or also includes elements inherent to such process, method, article, or apparatus / device.
[0037] So far, the technical solution of the utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings, but it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Without departing from the principle of the utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the utility model.
