Description

Technical Field

[0001] This utility model belongs to the field of railway rail transit technology, specifically relating to an adjustment device for the opening and locking amount of an externally locking turnout. Background Technology

[0002] Due to external environmental factors such as high train speeds, heavy vehicle compression, and poor track bed tamping, the geometric dimensions of turnout frames change. Turnout maintenance at the engineering and electrical junction is frequent, and seasonal and adaptive adjustments to turnouts on site have become a routine task.

[0003] The existing adjustment devices for the opening and locking distance of externally locking turnouts mainly rely on... Figure 1 The connecting piece 3 shown connects the actuating rod 1 and the locking rod connecting assembly of the switch machine to the hinged connecting rod 2. One end of the connecting piece 3 has a threaded hole that is threaded to the hinged connecting rod 2. The other end of the connecting piece 3 has a U-shaped opening, which is detachably connected to the bolt 4 in the bolt hole on the actuating rod 1 by a bolt. When adjusting the turnout opening and locking amount, it is necessary to disassemble the connection between the U-shaped opening of the connecting piece 3 and the actuating rod 1, and then adjust the connection between the connecting piece 3 and the hinged connecting rod 2 by using the threaded section 5 at the connecting end of the hinged connecting rod 2 and its locking nut 6. The connection and locking position of threaded section 5 is used to adjust the opening and locking amount of the turnout. However, it cannot be adjusted in one go and requires repeated measurement and readjustment. It also requires repeated disassembly and reassembly of the connection between the connecting part 3 and the action rod 1. The process is cumbersome and time-consuming. In addition, the track opening time is limited. The "vertical" track opening is only about 30 minutes. The short time and lack of experience of the operators make the turnout adjustment and disassembly work frequent. Often, the turnout cannot be adjusted to the optimal state as required. The turnout connecting the up and down lines cannot be effectively adjusted, which poses a hidden danger to safe production. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing technology requires frequent adjustment and disassembly of turnouts, and the turnouts connecting the up and down lines cannot be effectively adjusted, which poses a hidden danger to safe production.

[0005] To achieve the above objectives, this utility model provides an adjustment device for the opening and locking amount of an externally locking turnout, comprising a tubular body, an adjusting nut rotatably connected to one end of the tubular body, and a locking bolt provided on the side wall of the tubular body. The screw of the locking bolt is threadedly connected to the tubular body or to a locking nut fixed on the side wall of the tubular body, so that the screw can be screwed into and out of the cavity of the tubular body.

[0006] The head of the locking bolt is located outside the tubular body;

[0007] The other end of the tubular body is a U-shaped connection port with a radially penetrating bolt hole.

[0008] Furthermore, a neck is provided at one end of the tubular body, and an annular protrusion or multiple protrusions evenly arranged circumferentially are provided at the outer end of the neck away from the tubular body.

[0009] The adjusting nut is sleeved on the neck, and the inner end of the adjusting nut is provided with an annular retaining ring to abut against the annular protrusion or protrusion, preventing the adjusting nut from slipping off the neck.

[0010] The advantages of this utility model are: simple structure, convenient operation, low requirements for operators, short operation time, safety, and high reliability. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "aligned", "overlapping", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] To address the problems of frequent and inaccurate turnout adjustment and disassembly work in existing technologies, and the inability to effectively adjust crossover turnouts connecting up and down lines within a 30-minute "vertical" track window, thus posing a safety hazard, this embodiment provides a solution. Figure 2 The external locking turnout opening and locking adjustment device shown includes a tubular body 7, one end of which is rotatably connected to an adjusting nut 8. A locking bolt 10 is provided on the side wall of the tubular body 7. The screw of the locking bolt 10 is threadedly connected to the tubular body 7 or to a locking nut 9 fixed on the side wall of the tubular body 7, so that the screw can be screwed into and out of the cavity of the tubular body 7, thereby abutting against an object placed inside the tubular body 7, playing a clamping role, and limiting the position of the tubular body 7 and the object to remain relatively stationary.

[0022] Depend on Figure 1 As can be seen, the head of the locking bolt 10 is located outside the tubular body 7, facilitating clamping the head of the locking bolt 10 for adjustment. The other end of the tubular body 7 is a U-shaped connection port 11, i.e., a U-shaped opening, with a radially penetrating bolt hole. This design is consistent with existing technology and is mainly used for... Figure 1 The actuating rod 1 shown is fixedly connected by bolt 4.

[0023] Combination Figure 4 It can be clearly seen that the adjustment device for the opening and locking amount of the external locking turnout provided in this embodiment (equivalent to...) Figure 1The connecting piece 3 shown has its two ends connected to the actuating rod 1 and the hinged connecting rod 2 of the locking rod connecting assembly, respectively. The connection method with the actuating rod 1 is consistent with existing technology. The main difference is that the connection with the hinged connecting rod 2 of the locking rod connecting assembly is achieved through a threaded connection between the adjusting nut 8 and the threaded section 5 of the hinged connecting rod 2. Because the adjusting nut 8 is rotatably connected to the constricted neck 13 of the tubular body 7 (non-threaded connection), the tubular body 7 does not rotate with the adjusting nut 8 during forward or reverse rotation of the threaded section 5; it simply follows the rotation. Adjusting the nut 8 allows for linear forward or backward movement, thus enabling the adjustment of the opening and locking amount of the externally locked turnout without disassembling the connection between the tubular body 7 and the actuating rod 1. The connection between the tubular body 7 and the actuating rod 1 can be maintained to achieve the adjustment of the opening and locking amount of the externally locked turnout with an accuracy of 0.05mm. Compared to the repeated disassembly and assembly of existing technologies, this method is simpler, less time-consuming, and significantly improves operational efficiency. In particular, it allows the turnout to be adjusted to its optimal state as required, ensuring the reliability and safety of the work.

[0024] Combination Figure 3 It can be seen that one end of the tubular body 7 provided in this embodiment (i.e. Figure 2 The left end shown has a constricted neck 13, which is located away from the outer end of the tubular body 7 (i.e., Figure 2 The left end shown is the outer end) is equipped with Figure 3 The annular protrusion or multiple protrusions 14 evenly arranged circumferentially are shown; the adjusting nut 8 is sleeved on the constricted neck 13, and the inner end of the adjusting nut 8 is provided with an annular retaining ring 15 to abut against the annular protrusion or protrusion 14, preventing the adjusting nut 8 from slipping off the constricted neck 13. Since the adjusting nut 8 and the constricted neck 13 are not threadedly connected, the axial limit of the adjusting nut 8 is achieved only through the cooperation of the annular retaining ring 15 and the annular protrusion or protrusion 14, so that the adjusting nut 8 only makes circumferential motion relative to the constricted neck 13. When the adjusting nut 8 is threadedly connected to the threaded section 6 and rotates, it will naturally drive the constricted neck 13 to move axially. When the adjustment position meets the requirements, the locking nut 9 and the locking bolt 10 provided on the side wall of the tubular body 7 make the screw of the locking bolt 10 screwed into the tubular body 7 and abut against the threaded section 6 inside the tubular body 7, so as to limit the relative stationary position of the tubular body 7 and the threaded section 6. Finally, by Figure 1 or Figure 4 Tighten the locking nut 6 toward the adjusting nut 8 to lock the axial position of the tubular body 7. This completes the adjustment of the opening and locking amount of the external locking turnout. Throughout the adjustment process, there is no need to repeatedly disassemble and reassemble the connection between the tubular body 7 and the actuating rod 1, which greatly simplifies the operation, improves the adjustment accuracy, reduces the labor intensity and operational risks of the operators, and also ensures the effectiveness and timeliness of the adjustment operation, greatly reducing the adverse effects of the "window" time.
