Description

Technical Field

[0001] This utility model relates to the field of turnout switching resistance monitoring technology, specifically a turnout switching resistance monitoring connection component. Background Technology

[0002] Turnout switching resistance monitoring refers to the technical means of real-time monitoring of the resistance encountered by railway turnouts during the switching process. Turnouts are track connection devices that allow trains to switch from one track to another. They are one of the weakest links in the track, and their switching process is subject to complex forces, including tension, compression, and bending moments. They are also affected by environmental factors such as altitude and temperature. Over time, these factors can cause turnout deformation, leading to abnormal switching resistance and seriously affecting train operation safety.

[0003] The turnout switching resistance monitoring connection assembly is a device used to monitor the switching resistance of railway turnouts, primarily to ensure the safety and stability of trains during the switching process. This assembly typically includes several key components, such as fork-shaped irons, actuating rods, monitoring bolts, and backup bolts.

[0004] For example, utility model application No. 202021587901.2 discloses a turnout switching resistance monitoring connection assembly. This assembly, through the backup bolt, is not affected by the force between the fork-shaped iron and the actuating rod, thus ensuring the monitoring bolt's normal monitoring of the turnout switching resistance. Even if the monitoring bolt breaks, the fork-shaped iron and the actuating rod are connected by the backup bolt, allowing the railway turnout to continue switching. This solves the problem in the prior art where the turnout switching resistance monitoring bolt is at risk of breaking after prolonged operation, thus affecting train safety. However, the connection stability and structural strength of connection components similar to those in the aforementioned document are relatively limited, potentially leading to structural damage and preventing them from fulfilling their intended structural function.

One end of the fork-shaped component is horizontally inserted into the actuating rod component, and three sets of bolt components are vertically installed at the connection between the fork-shaped component and the actuating rod component. The lower end of the bolt components is threaded with a fixing nut. Limiting bolts are horizontally installed on both sides of the fork-shaped component and the actuating rod component, and limiting nuts are threaded on both ends of the limiting bolts. The fork-shaped component includes a fork-shaped body, a first through hole, a second through hole, a docking slot, a third through hole, and docking lug components.

[0009] Furthermore, the actuating rod component includes a main rod body, a first connecting hole, a second connecting hole, a mating tenon, a third connecting hole, and connecting lug components. The main rod body has a first connecting hole and a second connecting hole vertically opened at one end near the fork-shaped component, and a mating tenon is connected to the end of the main rod body near the fork-shaped component. The third connecting hole is vertically opened in the middle of the mating tenon. Connecting lug components are symmetrically arranged on both sides of the end of the main rod body near the fork-shaped component.

[0010] Furthermore, the first through hole, the second through hole, the first connecting hole, and the second connecting hole have the same structure, the third through hole and the third connecting hole have the same structure, and the first connecting hole, the second connecting hole, and the third connecting hole are all located on the same horizontal central axis.

[0011] Furthermore, the outer surface structure of the mating tenon matches the inner surface structure of the mating slot, and the main rod, mating tenon, and connecting ear component are welded together. Moreover, the connecting ear component has a horizontal hole structure in the middle, and the hole structure in the middle of the connecting ear component matches the surface structure of the limiting bolt.

[0012] Furthermore, the bolt component includes a monitoring bolt, a first fastening structure, a second fastening structure, and a pin hole. The monitoring bolt has a first fastening structure on its middle section surface, and a second fastening structure is provided at both the upper and lower ends of the first fastening structure. The monitoring bolt also has a pin hole horizontally opened at its bottom end.

[0013] Furthermore, the monitoring bolt, the first fastening structure, and the second fastening structure are fixedly connected, and the outer surface structures of the first fastening structure and the second fastening structure are matched with the inner surface structures of the first through hole, the second through hole, the first connecting hole, the second connecting hole, the third through hole, and the third connecting hole.

[0014] This utility model provides a turnout switching resistance monitoring connection component, which has the following beneficial effects:

[0015] 1. This utility model features a mating slot at one end of the fork-shaped body and a tenon at one end of the main rod. With this structure, when the fork-shaped body is mated with another fork-shaped body, the tenon can be inserted horizontally into the mating slot to form a mortise and tenon joint. Simultaneously, a set of bolts is vertically screwed into the third through hole and the third connecting hole. Combined with a fixing nut, this provides good structural connection stability for the two sets of bolts vertically installed inside the first through hole, the second through hole, and the first connecting hole and the second connecting hole. Furthermore, monitoring the first and second fastening structures on the bolt surfaces ensures the tightness and stability of the structure when the bolts are inside the first through hole, the second through hole, the first connecting hole, the second connecting hole, and the third through hole and the third connecting hole, reducing unnecessary structural loosening.

This ensures structural strength while maximizing structural lifespan and minimizing unnecessary structural damage. Furthermore, the above structural design is simple and can be selectively used, ensuring both ease of use and flexibility. Attached Figure Description

Symmetrical mating lugs 106 are provided on both sides of one end of hole 105. The first through hole 102, the second through hole 103, the mating slot 104, and the third through hole 105 are all on the same horizontal central axis. The fork-shaped body 101 and the mating lugs 106 are welded together. The middle of the mating lugs 106 has a horizontal hole structure, and the hole structure in the middle of the mating lugs 106 matches the surface structure of the limit bolt 5. When the fork-shaped body 101 is mated with the fork-shaped body 101, the mating tenon 204 can be inserted into the interior of the mating slot 104 in the horizontal direction to form a tenon and mortise mating structure. At the same time, a set of bolt components 3 are vertically screwed into the interior of the third through hole 105 and the third connecting hole 205. With the use of the fixing nut 4, the two sets of bolt components 3 installed vertically inside the first through hole 102, the second through hole 103, the first connecting hole 202, and the second connecting hole 203 can be assisted to provide good structural connection firmness.

[0025] like Figures 1 to 5As shown, the actuating rod component 2 includes a main rod body 201, a first connecting hole 202, a second connecting hole 203, a mating tenon 204, a third connecting hole 205, and connecting lug components 206.

The third through hole 105 and the third connecting hole 205 have the same structure. The first connecting hole 202, the second connecting hole 203, and the third connecting hole 205 are all on the same horizontal central axis. The outer surface structure of the mating tenon 204 matches the inner surface structure of the mating slot 104. The main rod 201, the mating tenon 204, and the connecting ear member 206 are welded together. Moreover, the connecting ear member 206 has a horizontal hole structure in the middle. Furthermore, the hole structure in the middle of the connecting ear member 206 matches the surface structure of the limiting bolt 5.
