Description

Technical Field

[0001] The utility model belongs to the field of compensating rope anti-deviation and anti-abrasion, and particularly relates to an auxiliary device for preventing deviation and abrasion of a catenary compensating rope. Background Technique

[0002] With the rapid development of China's railway transportation industry, the requirements for the railway power supply system are increasing day by day. As a key facility for electric locomotives to obtain electric energy, the stability and reliability of the railway catenary are directly related to the safe operation of trains. Article 126 of the "General Rules for Operation and Maintenance of Regular-speed Railways of China National Railway Corporation" clearly stipulates that the compensating rope shall not rub against other components to avoid problems such as wear, strand breakage, and even wire breakage caused by friction. These problems will not only reduce the working efficiency of the compensating device but also pose a threat to the safety of train power supply.

[0003] However, in actual applications, the operating environment of the catenary compensating device is complex and changeable, and often faces the following challenges:

[0004] Installation position limitation: On certain specific railway lines, due to terrain conditions, the installation position of the compensating device may be restricted, resulting in a change in the lower anchor angle. This change in angle causes a deviation in the relative position between the compensating rope and the compensating pulley, increasing the possibility of friction.

[0005] External pillar skew: Natural and human factors along the railway may cause the pillar to skew. The skew of the pillar will further exacerbate the deviation and abrasion between the compensating rope and the pulley, making the operation of the equipment inflexible.

[0006] Long-term operation wear: Even under normal circumstances, the compensating rope will gradually wear during long-term operation. Especially in the case of deviation and abrasion, the wear rate will increase significantly, eventually leading to strand breakage or even fracture of the compensating rope. Once the compensating rope breaks, the tension of the catenary will drop rapidly, and normal power supply cannot be achieved, seriously affecting the operation safety of trains.

[0007] High maintenance cost: Due to the frequent replacement and maintenance of the compensating rope, the railway department needs to invest a large amount of manpower and material resources for regular inspections and maintenance, increasing the operating cost.

[0008] Based on this, the utility model proposes an auxiliary device for preventing deviation and abrasion of a catenary compensating rope. Content of the Utility Model

[0009] To solve the above problems in the prior art, that is, the change in the lower anchor angle caused by limited installation position, the additional wear caused by external pillar skew, the accelerated wear and fracture risk during long-term operation, and the high maintenance cost, the utility model provides an auxiliary device for preventing deviation and abrasion of a catenary compensating rope, including a fixed end, an adjusting end, and a clamping end;

[0010] The fixed end is fixed to the support part of the compensation device. An adjusting end that moves along its length is installed on the fixed end, and a clamping end that can swing along it is installed on the adjusting end. The clamping end is fixed to the welding ring of the double-ring rod of the compensation device.

[0011] In some preferred embodiments, the fixed end includes a snap ring, a bolt, and a first nut;

[0012] The snap ring is clamped on the support part of the compensation device. The bolt passes through the snap ring and is threadedly connected to the support part, and is tightened and locked by the first nut to realize the locking and fixing between the snap ring and the support part.

[0013] In some preferred embodiments, the support part is the drop-anchor angle steel base of the compensation device.

[0014] In some preferred embodiments, the adjusting end includes a first connecting rod, a snap pin, a long slot, a first screw rod, a second nut, and a swinging hole;

[0015] The first connecting rod is fixed to the snap ring. A swinging hole is formed in the first connecting rod. A first screw rod that swings along it is arranged in the swinging hole. A long slot is formed in the first screw rod along its length direction. Two snap pins that move along it are arranged in the long slot. The snap pins are arranged on both sides of the first connecting rod. The first screw rod is threadedly connected to two second nuts. The second nuts are used to adjust the positions of the snap pins, so as to fix the first connecting rod and the first screw rod. By adjusting the positions of the snap pins in the long slot, the inclination angle of the first screw rod is adjusted;

[0016] The clamping end that moves along the length direction of the first screw rod is arranged on the first screw rod.

[0017] In some preferred embodiments, the clamping end that moves along the length direction of the first screw rod is arranged on the first screw rod, and its specific structure is:

[0018] The first screw rod is arranged in a second through hole. The second through hole is formed in a connecting plate. Through the second through hole, the connecting plate moves along the length direction of the first screw rod. A third nut is respectively arranged on the upper and lower sides of the connecting plate. The two third nuts are used to clamp the connecting plate. The connecting plate is fixed to the clamping end.

[0019] In some preferred embodiments, the first connecting rod and the first screw rod are perpendicularly arranged.

[0020] In some preferred embodiments, the clamping end is a hoop.

[0021] In some preferred embodiments, the length direction of the long strip hole is parallel to the length direction of the first screw.

[0022] In some preferred embodiments, the two second nuts are respectively arranged on the sides of the two pins away from the first connecting rod.

[0023] Advantages of the present utility model:

[0024] Reduce wear: Through the design of the adjusting end, the device can adapt to the requirements of different installation positions.

[0035] The following further elaborates on the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and are not intended to limit the utility model. Additionally, it should be noted that for ease of description, only parts related to the relevant utility model are shown in the drawings.

[0036] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will elaborate on the present application in detail with reference to the drawings and embodiments.

[0037] As Figures 1-5 shown, referring to Figure 1 , Figure 2 and Figure 5 , the present utility model provides an anti-deviation wear auxiliary device for a catenary compensation rope, including a fixed end 1, an adjustment end 2, and a clamping end 3;

[0038] The fixed end 1 is fixed to the support part of the compensation device. An adjustment end 2 that moves along its length is installed on the fixed end 1. A clamping end 3 that can swing along it is installed on the adjustment end 2. The clamping end 3 is fixed to the double-ring rod welding ring 4 of the compensation device.

[0039] Among them, the clamping end 3 is a clamp. Two pieces of the clamp are fixed to the double-ring rod welding ring 4 of the compensation device by using fixing bolts. The cooperation between the bolts and the clamp is a prior art and will not be elaborated here.

[0040] The fixed end 1 in the present utility model is designed as a high-strength metal part, which can be firmly installed on the support part of the compensation device. This part has sufficient strength and stability to ensure its core role in the entire device - that is, as the basis for other components.

[0041] In this embodiment, referring to Figure 1 and Figure 2 , the fixed end 1 includes a snap ring 11, a bolt 12, and a first nut 13;

[0042] The snap ring 11 is clamped on the support part of the compensation device. The bolt 12 passes through the snap ring 11 and is threadedly connected to the support part, and is tightened and locked by the first nut 13 to achieve the locking and fixing between the snap ring 11 and the support part.

[0043] Among them, the snap ring 11 can be understood as an n-shaped channel steel.

[0044] In this utility model, the snap ring 11 is clamped on the support part, that is, on the drop-anchor angle steel base 5 of the compensation device, and then the bolt 12 is passed through the snap ring 11 and threadedly connected to the drop-anchor angle steel base 5 to ensure a firm connection between the fixed end 1 and the drop-anchor angle steel base 5.

[0045] The adjusting end 2 is installed on the fixed end 1 and can be moved along the length direction of the fixed end through threaded or other mechanical connection methods. This design allows the position of the adjusting end 2 to be adjusted according to the actual installation position and the state of the compensation rope to adapt to different working conditions.

[0046] In this embodiment, referring to Figure 1 , the adjusting end 2 includes a first connecting rod 21, a snap pin 22, a long slot 23, a first screw 24, a second nut 25, and a swing hole 28;

[0047] The first connecting rod 21 is fixed to the snap ring 11. A swing hole 28 is provided in the first connecting rod 21. A first screw 24 that swings along it is arranged in the swing hole 28. A long slot 23 is provided along the length direction of the first screw 24. Two snap pins 22 that move along it are arranged in the long slot 23. The snap pins 22 are arranged on both sides of the first connecting rod 21. The first screw 24 is threadedly connected to two second nuts 25. The second nuts 25 are used to adjust the position of the snap pins 22, thereby fixing the first connecting rod 21 and the first screw 24. By adjusting the position of the snap pins 22 in the long slot 23, the inclination angle of the first screw 24 is adjusted; a clamping end 3 that moves along the length direction of the first screw 24 is provided on the first screw 24.

[0048] The specific adjustment process of the adjusting end 2 is as follows:

[0049] Preparation: Confirm that the position of the adjusting end 2 needs to be adjusted to optimize the working state of the compensation rope, reduce wear, or ensure appropriate tension.

[0050] Loosen the fixing nuts: Use a suitable tool such as a wrench to loosen the second nuts 25 at both ends of the first screw 24. The function of these nuts is to lock the position of the snap pins 22. Therefore, loosening them can release the adjusting end 2 and enable it to move freely on the first connecting rod 21.

[0051] Move the adjusting end: Push or pull the adjusting end 2 by hand to move it along the length direction of the first connecting rod 21 to a new predetermined position. The first connecting rod 21 is fixed, and the position of the adjusting end 2 is changed by the movement of the snap pins 22 in the long slot 23.

[0052] Adjust to the appropriate position: According to the actual situation, move the adjustment end 2 to the position that can minimize the friction between the compensating rope and the pulley. This position should ensure the smooth operation of the compensating rope while maintaining appropriate tension.

[0053] Fasten the adjustment end: After the adjustment end 2 reaches the ideal position, tighten the two second nuts 25 again. Ensure that the second nuts 25 tightly press on the first screw rod 24, so that the pin 22 is fixed at the corresponding position in the long slot 23, thereby firmly fixing the adjustment end 2 on the first connecting rod 21.

[0054] Inspection and confirmation: Carefully check whether all components are correctly installed and firmly fixed. In particular, confirm whether the position of the adjustment end 2 can indeed help reduce the wear of the compensating rope and whether the compensating rope has appropriate tension.

[0055] Test run: On the premise of not affecting normal operation, let the catenary compensation device conduct a short test run, observe the working state of the compensating rope, and ensure that no abnormal situation occurs. If necessary, fine-tune until the best effect is achieved.

[0056] In addition, for specific reference Figure 2 、 Figure 3 and Figure 4 , by adjusting the position of the pin 22 in the long slot 23, the present invention can make the first screw rod 24 tilt and swing along the swing hole 28, so as to drive the clamping end 3 to be fixed with the double-ring rod welding ring 4 at different tilt angles.

[0057] See Figure 3 As shown, the swing direction of the first screw rod 24 tilting and swinging along the swing hole 28 is the up and down direction in Figure 3 .

[0058] Among them, the length direction of the long slot 23 is parallel to the length direction of the first screw rod 24.

[0059] In the present invention, the two second nuts 25 are respectively arranged on the side of the two pins 22 away from the first connecting rod 21.

[0060] See Figure 2 and Figure 3 , the clamping end 3 that moves along the length direction of the first screw rod 24 is arranged on the first screw rod 24, and its specific structure is:

[0061] The first screw rod 24 is arranged in the second through hole which is opened on the connecting plate 26. The connecting plate 26 is moved along the length direction of the first screw rod 24 through the second through hole. A third nut 27 is arranged on each of the upper and lower sides of the connecting plate 26. The two third nuts 27 are used to clamp the connecting plate 26, and the connecting plate 26 is fixed to the clamping end 3.

[0062] The specific process of the clamping end 3 moving along the first screw rod 24 is as follows:

[0063] Determine the movement requirement: First, the operator needs to evaluate the state of the compensating rope to determine whether the clamping end 3 needs to be adjusted in position, as well as the specific movement direction and distance. This is usually to optimize the path of the compensating rope and reduce friction with pulleys or other components.

[0064] Loosen the third nuts 27: Use a suitable tool such as a wrench to loosen the two third nuts 27 located on the upper and lower sides of the connecting plate 26. The function of these nuts is to fix the connecting plate 26 so that it cannot move along the first screw rod 24. After loosening the nuts, the connecting plate 26 will be able to slide freely on the first screw rod 24.

[0065] Move the connecting plate 26: Push or pull the connecting plate 26 by hand to move it along the length direction of the first screw rod 24 to a new predetermined position. Ensure that the connecting plate 26 is stable during the movement and does not get stuck or tilted.

[0066] Adjust to the appropriate position: According to the actual situation, move the connecting plate 26 to the position that can minimize the friction between the compensating rope and the pulley. This position should ensure the smooth operation of the compensating rope while maintaining appropriate tension.

[0067] Fasten the connecting plate 26: When the connecting plate 26 reaches the ideal position, tighten the two third nuts 27 again. Ensure that the two third nuts 27 tightly clamp the connecting plate 26 to fix it at the corresponding position on the first screw rod 24.

[0068] Check and confirm: Carefully check whether all components are correctly installed and firm. In particular, confirm whether the positions of the connecting plate 26 and the clamping end 3 can indeed help reduce the wear of the compensating rope and whether the compensating rope has appropriate tension.

[0069] Test run: Without affecting normal operation, let the catenary compensation device conduct a short trial run, observe the working state of the compensation rope, and ensure that no abnormal conditions occur. If necessary, fine-tuning can be carried out until the best effect is achieved. Check the movement effect: Finally, the operator needs to check the effect after movement to ensure that the clamping end 3 and the compensation rope no longer have unnecessary friction with the pulley or other components. This involves observing the movement trajectory of the compensation rope, measuring the change in the tension of the compensation rope, etc. If the movement effect is found to be not good, the above steps need to be repeated until a satisfactory result is achieved.

[0070] Wherein, the first screw rod 21 and the second screw rod 22 are vertically arranged.

[0071] The main function of the clamping end 3 is to be connected to the double-ring rod welding ring 4 of the compensation device through a clamping mechanism, so as to fix the compensation rope and reduce or eliminate the eccentric wear phenomenon between the compensation rope and the pulley.
