Description

Technical Field

[0001] The utility model belongs to the technical field of railway turnout indicating rods, and more specifically, particularly relates to a climbing type pointed rail indicating rod with adjustable notch length. Background Art

[0002] Turnouts and their switching equipment are important basic equipment for railways, which are directly related to the safety and efficiency of railway driving. Among the signal failures that affect driving safety, turnout failures account for a large proportion. At present, my country's high-speed railways generally use large-number turnouts of No. 42, No. 30 or No. 38, and most of these turnouts are laid at the junction of the connecting line and the two lines, which are relatively far away from the signal maintenance area or have relatively inconvenient transportation. Once the equipment fails, it will affect the operation of the train and cause interference to transportation if it is not handled in time. The large-number turnout point rail has a large creep volume, which has a great impact on the switch machine gap and is easy to get stuck in the gap and cause failures.

[0003] At the same time, the current adjustment of the switch secret sticker of the split external locking turnout is basically carried out in the middle of the track, which requires the cooperation of multiple people, causing inconvenience to the on-site signal workers. If the adjustment can be carried out on the switch machine side, the number of people can be reduced and the adjustment can be convenient. In addition, the existing installation method, the state of the turnout, the turning back and creeping of the point rail, etc. also have a great impact on the change of the switch machine gap. On the movable heart rail, the existing installation adjustment method is under the wing rail, which is very inconvenient to adjust and prone to errors.

[0004] Checking whether the switch point rail is in the specified position is an indispensable part of railway switching equipment. It is usually checked by the switch machine indicator rod. The main inspection method is to require the switch machine inspection block to align the indicator gap. On-site maintenance requires frequent adjustment of the rod length to ensure that the switch machine indicator gap meets the standard requirements.

[0005] Existing adjustment mechanism applications such as Figure 1 As shown, the indicating rod is connected to the circular hole of the joint movable head at the lower part of the flexible joint. The buckle sleeve 3 is driven to rotate by the buckleless sleeve 2 to move the indicating connecting rod to adjust the position of the indicating rod. Whether the position of the indicating rod is appropriate needs to be judged by observing the relative position of the indicating notch and the inspection block at the switch machine. After the indicating is adjusted, the buckleless sleeve 2 is pressed against and fixed with the nut 1.

[0006] The existing structure has the problem that the buckled shaft sleeve 3 and the buckleless shaft sleeve 2 are not easy to align during adjustment, and repeated adjustment and testing are required. In particular, when the train running density is high and the construction time is very tight, it is difficult to adjust the switch gap once. At the same time, the indicating connecting rod is rigidly connected to the rail through a flexible joint. During use, due to the frequent influence of severe vibration of the train, vibration impact occurs between the flexible joint, the indicating rod and the connecting shaft sleeve, which affects the stability and life of the equipment.

[0007] Therefore, developing an adjustment mechanism that can quickly and accurately adjust the gap of the switch machine, better adapt to adverse conditions such as turnout creep and stock rail overturning, and reduce the probability of on-site failures has significant economic and social benefits for ensuring train operation safety, improving maintenance efficiency, and reducing the maintenance labor intensity of signal workers. Summary of the Invention

[0008] To solve the above technical problems, the present utility model provides a creep-adaptable stock rail indicating rod with adjustable gap length to solve the technical problems in the prior art that the traditional large-number indicating rod has a large creep amount, has a great impact on the switch machine gap, is prone to jamming the gap and causing failures, and is very inconvenient to adjust and prone to errors.

[0013] As a further scheme of the present utility model, one end of the adjusting sleeve is inserted into the through hole. One end of the elastic reed contacts the adjusting sleeve, and the other end is connected with the hole plug. The elastic reed can be selected from multiple standard disc springs.

Detailed Embodiment

[0026] The following further describes the implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the technical solutions of the present utility model, but cannot be used to limit the protection scope of the present utility model.

[0027] Embodiment:

[0028] As shown in the Figures 1 to 2 accompanying drawings:

[0029] The present utility model provides a climbing-type switch rail indicating rod with adjustable notch length, which includes an indicating rod 11 and an adjustable tip iron 17. One end of the indicating rod 11 is bent upward, removing the complex flexible joint in the traditional indicating rod, simplifying the overall structure, reducing the mass, and being beneficial to reducing the influence of vibration and impact; a threaded end is provided at the top of the bent part of the indicating rod 11. Through this threaded end, the indicating rod 11 is connected with a steel sleeve 20 and an insulating sleeve 21. A screw joint 12 is clamped between the steel sleeve 20 and the insulating sleeve 21. An adjusting component is provided on one side of the screw joint 12. Through this adjusting component, the adjustable tip iron 17 is connected to the screw joint 12, which not only simplifies the structure of the indicating rod 11, but also enables the adjustable tip iron 17 to be quickly adjusted through the adjusting component, realizing the function of adjusting the notch length. Compared with the traditional indicating rod, this switch rail indicating rod adopts an optimized integrated structure, realizes the adjustable function by setting the adjusting component, reduces the mass, improves the flexibility of adjustment, and better meets the needs under different working conditions.

[0030] Among them, as shown in the Figure 2 accompanying drawings, the adjusting component includes an adjusting sleeve 13. A threaded end is provided at one end of the screw joint 12 away from the indicating rod 11, and a threaded hole is correspondingly opened on one side of the adjusting sleeve 13. Through this structure, the threaded end of the screw joint 12 can be screwed into the threaded hole inside the adjusting sleeve 13. When using this switch rail indicating rod, by simply adjusting the depth of the adjusting sleeve 13 screwed into the screw joint 12, the connection length between the adjustable tip iron 17 and the indicating rod 11 can be conveniently adjusted, thereby realizing the adjustment of the notch size; solving the problem that the traditional switch rail indicating rod needs to be repeatedly tightened and loosened to adjust the notch size, bringing great convenience to users; at the same time, stepless fine adjustment can also be performed in the state without a notch to meet the needs in different scenarios; through the setting of the adjusting component, not only can the notch size be conveniently and flexibly adjusted, but also the applicability of this switch rail indicating rod is greatly improved.

[0031] In addition to the adjusting sleeve 13, the adjusting component further includes an elastic reed 14 and a hole plug 15. One end of the adjustable tip iron 17 is provided with a through hole, and the elastic reed 14 and the hole plug 15 are arranged in this through hole. Among them, one end of the elastic reed 14 contacts the adjusting sleeve 13, and the other end is connected to the hole plug 15. In order to have good elasticity, multiple standard disc springs are used for the elastic reed 14. When the user needs to adjust the screwing depth of the screw joint 12 in the threaded hole by rotating the adjusting sleeve 13, the adjusting sleeve 13 will be subjected to the pressure of the elastic reed 14. Specifically, it can eliminate the looseness feeling during the rotation of the adjusting sleeve 13, so that the adjusting size is more accurate. By setting the elastic reed 14, the entire adjusting component is stable and reliable during use, bringing a better adjusting experience to the user.

[0032] One end of the adjusting sleeve 13 is inserted into the through hole. The outer surface of the adjusting sleeve 13 adopts a smooth circular structure, and the part extending out of the adjustable tip iron 17 at one end is hexagonal. Through this hexagonal structure extending out, the user can conveniently use a special tool for rotation operation. By rotating the hexagonal part of the adjusting sleeve 13, the screwing adjustment of the screw joint 12 inside the adjusting sleeve 13 can be realized, which not only ensures the compact internal structure of the adjusting component but also takes into account the convenience of external operation. The user only needs to use a simple tool to rotate the hexagonal part to adjust the length of the screw joint 12 screwed into the adjusting sleeve 13.

[0033] The hole plug 15 is installed from the side of the adjustable tip iron 17 close to the switch rail. By rotating the hole plug 15, the adjusting sleeve 13 and the elastic reed 14 can be pressed tightly. In order to keep the elastic reed 14 in an effectively pressed state, the outer side of the hole plug 15 adopts an inclined angle structure. When rotating and pressing through the hole plug 15 to press the adjusting sleeve 13 and the elastic reed 14 in place, since the outer inclined angle part of the hole plug 15 will be restricted by the bottom angle of the switch rail, the hole plug 15 cannot continue to rotate. Through this structural setting, it can be ensured that no matter how it is operated, the elastic reed 14 will always be in an effectively pressed state.

[0034] The adjusting component has been further optimized in terms of ensuring adjustment reliability. Specifically, a backup nut 16 is also provided at the threaded end of the screw joint 12. One side of the backup nut 16 is in contact and fixed with the adjusting sleeve 13. After the screw joint 12 is screwed into the adjusting sleeve 13, the user can make necessary size adjustments. After the adjustment work is completed, the adjusted screw joint 12 and the adjusting sleeve 13 can be fixed against loosening by the backup nut 16, thus ensuring the adjustment accuracy and preventing size changes caused by loosening at the same time.

[0035] Among them, please refer to as Figure 2As shown in the figure, a limiting device 19 is provided at a position near the middle on the indicating rod 11. The limiting device 19 is fixed on the proximal basic rail or the switch installation device. In this way, when the switch rail undergoes length changes due to the rise and fall of the ambient temperature and thus creeps, the limiting device 19 can limit the possible horizontal swing of the indicating rod 11 caused by the creep of the switch rail. At the same time, when the switch rail expands and contracts in the horizontal direction, due to the limitation of the limiting device 19, the indicating rod 11 cannot swing in the horizontal direction either. It can only make a slight rotation around the horizontal axis. This enables the screw joint 12 and the adjusting sleeve 13 to rotate within the adjustable tip iron 17.

[0036] An articulated bearing 18 is provided at one end of the indicating rod 11 away from the adjusting component. The function of the articulated bearing 18 is to connect with the switch machine. At the same time, by restricting the possible horizontal swing of the indicating rod 11 caused by the creep of the switch rail through the limiting device 19, it is converted into a slight rotational movement around the long axis, and this slight rotation is absorbed and eliminated by means of the articulated bearing 18. The problem of the length change of the indicating rod 11 caused by the creep of the switch rail is solved. This also enables the indicating rod 11 to better adapt to the complex track conditions with a certain degree of irregularity. At the same time, through the limitation of the limiting device and the absorption of the articulated bearing 18, it effectively prevents faults such as notch jamming that may be caused by creep, thereby improving the use stability of this adjusting component. It not only ensures the connection with the switch machine but also enhances the working reliability of the component itself in adverse environments.

[0037] In order to further improve the reliability and service life of this switch rail indicating rod, an oil injection hole through which lubricating oil can be injected is provided on the adjustable tip iron 17. Through this oil injection hole, lubricating oil can be regularly injected into the interior of the component to achieve the lubrication effect. This effectively ensures the smooth operation of each moving part of the component during long-term operation and reduces the occurrence of faults caused by interference wear. At the same time, the oil injection structure also facilitates the necessary maintenance of the component in the future. Only by replenishing lubricating oil through the oil injection hole can the maintenance purpose be achieved. This is very beneficial for reducing the maintenance difficulty and cost, and can further reduce various possible faults of this adjusting component, and on this basis, improve its overall working stability again.

[0038] The specific usage mode and function of this embodiment: One end of the indicating rod 11 is bent upward, removing the complex flexible joint in the traditional indicating rod, simplifying the overall structure and reducing the weight. The bent part is provided with a threaded end. Through the threaded end, the steel sleeve 20, the insulating sleeve 21 and the screw joint 12 can be connected together. One end of the screw joint 12 is connected with an adjusting component.

[0039] The adjusting component includes an adjusting sleeve 13, a resilient reed 14 and a hole plug 15. The screw joint 12 is connected by screwing its threaded end into the threaded hole in the adjusting sleeve 13. One end of the resilient reed 14 contacts the adjusting sleeve 13, and the other end is connected to the hole plug 15. The adjusting sleeve 13 is fixed by a backup nut 16 to prevent loosening.

[0040] During use, by rotating the adjusting sleeve 13, the adjustable tip iron 17 moves back and forth relative to the indicating rod 11 to adjust the size of the notch, solving the problem of inconvenient adjustment of the traditional indicating rod and improving the applicability.

[0041] A limiting device 19 is provided on the indicating rod 11, which can limit the possible horizontal swing of the indicating rod 11 caused by the creep of the switch rail, convert it into a slight rotational movement around the long axis, and absorb and eliminate it through the spherical plain bearing 18, and prevent the notch jamming fault caused by creep, improving the stability.
