Abstract
Description
Technical Field
[0001] This utility model relates to balance wheel technology, and more particularly to a tension balance wheel for high-speed railway lines. Background Technology
[0002] Balance wheels are used in high-speed rail lines, positioned between an insulating rod and a compensating ratchet, connected by a compensating rope. When the compensating rope, passing over the balance wheel, is exposed to wind and sun, it can develop cracks, broken strands, and other damage. Additionally, the anchoring rope may rub against the guide anchor ratchet base. This leads to an imbalance at both ends of the compensating rope, causing the compensating ratchet to shift at an angle and position. Therefore, the balance wheel needs maintenance. Currently, maintenance requires equipment such as a level, which is time-consuming, inconvenient, and hinders the efficiency of time-sensitive maintenance work. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model proposes a tensioning balance wheel for high-speed railway lines.
[0004] The technical solution of this utility model is implemented as follows:
[0005] A tension balance wheel for high-speed railway lines includes:
[0006] A balance wheel, wherein an annular groove is formed in the middle of the balance wheel, and first teeth are provided on both sides of the annular groove;
[0007] Fixed plates are provided at the upper and lower ends of the balance wheel, and positioning pins are provided at both ends of the fixed plates. The balance wheel is set in the middle of the two fixed plates through the positioning pins.
[0008] And a balance block disposed between the fixed plate and the fixed plate, the balance block having a second tooth that mates with the first tooth, the balance block being installed between the fixed plate and the fixed plate by a bolt.
[0009] In this tensioning balance wheel for high-speed railway lines, the balance block is provided with a strip groove, and the bolt is set in the strip groove.
[0010] In this tensioning balance wheel for high-speed railway lines, the fixed plate is provided with symmetrically arranged parallel protrusions, and the balance block is provided with parallel grooves that cooperate with the parallel protrusions.
[0011] In this tensioning balance wheel for high-speed railway lines, the height of the parallel protrusion is greater than the depth of the parallel groove.
[0012] In this tensioning balance wheel for high-speed railway lines, the balance block is provided with scale lines.
[0013] The tensioning balance wheel for high-speed railway lines described in this invention has the following advantages: By observing the position of the scale lines on the balance block, it is possible to determine whether the balance wheel is tilted, facilitating quick maintenance by inspection personnel. Furthermore, the visible balance block improves maintenance efficiency, saves time, and reduces the difficulty of maintenance. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the tensioning balance wheel structure for high-speed railway lines according to this utility model;
[0015] Figure 2 for Figure 1 The main view;
[0016] Figure 3 for Figure 1 Exploded view. Detailed Implementation
[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0018] like Figures 1 to 3 As shown, this utility model of a tensioning balance wheel for high-speed rail lines includes a balance wheel 1, a fixing plate 2, and a balance block 3.
[0019] An annular groove 4 is formed in the middle of the balance wheel 1, and first teeth 5 are provided on both sides of the annular groove 4. A compensating rope is installed in the annular groove 4. After the compensating rope passes around the balance wheel 1, its two ends are placed on both sides of the compensating ratchet and wound around it, so two ropes are formed. When one of the ropes breaks, comes apart, or is damaged, it will cause uneven stress on both ends of the compensating rope, which will cause the balance wheel 1 to shift or tilt, affecting the position of the insulating rod and the compensating ratchet.
[0020] Fixing plates 2 are positioned at the upper and lower ends of the balance wheel 1, forming an installation area 6 between the fixing plates 2. The balance wheel 1 and the balance block 3 are positioned within the installation area 6. Positioning pins 7 are provided at both ends of the fixing plates 2, and the balance wheel 1 is positioned between the two fixing plates 2 via the positioning pins 7. The balance wheel 1 is mounted on one end of the fixing plate 2, and the other end is connected to the insulating rod via a traction component.
[0021] The balance block 3 is positioned between the fixed plate 2 and the fixed plate 2. The balance block 3 has a second tooth 8 that engages with the first tooth 5. When one end of the compensating rope is damaged, the tension at that end decreases, causing the compensating rope to rotate the balance wheel 1. This, in turn, causes the first tooth 5 on the balance wheel 1 to drive the second tooth 8 on the balance block 3. This causes the balance block 3, originally positioned in the middle of the fixed plate 2, to move to one end, resulting in more graduations 9 on one end and fewer graduations 9 on the other, facilitating quick diagnosis by maintenance personnel.
[0022] The balance block 3 is installed between the fixed plate 2 and the fixed plate 2 by a bolt 10. The fixed plate 2 is provided with a pin hole 11 and a positioning hole 12. The bolt 10 is set in the positioning hole 12 and the positioning pin 7 is set in the pin hole 11.
[0023] A strip groove 13 is provided on the balance block 3, and a bolt 10 is set in the strip groove 13. The strip groove 13 facilitates the installation of the balance block 3, allowing it to move within a certain length range, and the maximum position of movement is limited by the bolt 10.
[0024] The fixed plate 2 has symmetrically arranged parallel protrusions 14, and the balance block 3 has parallel grooves 15 that mate with the parallel protrusions 14. The height of the parallel protrusions 14 is greater than the depth of the parallel grooves 15. The parallel protrusions 14 and parallel grooves 15 can guide the sliding position of the balance block 3.
[0025] The balance block 3 is equipped with scale lines 9, which makes it easy for maintenance personnel to make quick judgments and observe whether the balance wheel 1 is tilted at an angle.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
