Abstract
Description
Technical Field
[0001] This utility model relates to the field of track inspection instrument technology, and in particular to a quick-release connector for a split-type track inspection instrument. Background Technology
[0002] With the rapid development of my country's railways and urban rail transit, the daily maintenance requirements for these lines have also reached a high level. To ensure the safe and stable operation of railways, the workload of line maintenance personnel is constantly increasing, and track inspection instruments, as commonly used equipment for railway line inspection, have been widely applied.
[0003] Existing track inspection instruments are mainly H-type and T-type in structure. Since the stability of the structure directly affects the stability and accuracy of the measurement parameters, a monolithic structure is generally adopted. However, the monolithic structure is large and heavy, making it inconvenient for field personnel to handle, and in some narrow places or steep slopes, it can even pose significant difficulties and safety risks. Therefore, there is a strong need for a more easily transportable, modular track inspection instrument. A modular track inspection instrument divides the longitudinal and transverse beams into two parts, reducing the size and weight of each component and facilitating field handling. Furthermore, disassembling the original monolithic T-type structure also reduces the size and weight of the packaging box. Currently, most modular track inspection instruments use locating pins for assembly. The locating pins have threads at the front end, and are tightened with nuts after positioning. The problems with using locating pins are that they are difficult and inconvenient to install and remove, have low accuracy, and are prone to loosening. Secondly, current modular track inspection instruments lack integrated electrical circuits and electrical connection components, thus requiring improvement. Utility Model Content
[0004] Therefore, it is necessary to provide a quick-release connector for a split-type track inspection instrument to address the above problems.
[0005] A split-type track inspection instrument quick-release connector includes a crossbeam and a longitudinal beam. The crossbeam has a crossbeam connector at its end, and the longitudinal beam has a longitudinal beam connector on its side. The crossbeam connector and the longitudinal beam connector are detachably connected, forming a T-shaped structure. The longitudinal beam connector has a positioning hole, and a latch hook is located on its outer side. An electrical connection socket is located inside the longitudinal beam connector. The crossbeam connector has a positioning post that matches the positioning hole, and a self-locking latch is located on its outer side. The latch ring and latch hook are detachably connected. An electrical connection plug, which is electrically connected to the electrical connection socket, is located inside the crossbeam connector.
[0006] Preferably, the positioning hole includes a main positioning hole and a secondary positioning hole, and the positioning post includes a main positioning post and a secondary positioning post. The main positioning post is matched and inserted into the main positioning hole, and the secondary positioning post is matched and inserted into the secondary positioning hole.
[0007] Preferably, the secondary positioning hole and the secondary positioning post adopt an elliptical structure.
[0008] Preferably, the crossbeam connector and the longitudinal beam connector are made of stainless steel by milling.
[0009] Preferably, there are two secondary positioning holes, which are arranged on both sides of the main positioning hole to form a triangular positioning.
[0010] The advantages of this utility model are: the split-type track inspection instrument integrates electrical connection function, which can realize quick connection of electrical circuit, eliminates the need for two people to carry it together, and facilitates transportation. In places with poor working conditions such as steep slopes, it can greatly reduce the potential safety hazards of collaborative transportation. At the same time, the detachable structure also facilitates storage. Attached Figure Description

Figure 2 This is a schematic diagram of the crossbeam connector structure; Figure 3 This is a schematic diagram of the longitudinal beam connector structure; Figure 4 This is a schematic diagram of another embodiment of the longitudinal beam connector. Detailed Implementation
[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0013] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0015] like Figures 1-3As shown, a split-type track inspection instrument quick-release connector includes a crossbeam 100 and a longitudinal beam 200. The end of the crossbeam 100 is provided with a crossbeam connector 1, and the side of the longitudinal beam 200 is provided with a longitudinal beam connector 2. The crossbeam connector 1 and the longitudinal beam connector 2 are detachably connected, so that the crossbeam 100 and the longitudinal beam 200 form a T-shaped structure. The longitudinal beam connector 2 is provided with a positioning hole 21, and the outer side of the longitudinal beam connector 2 is provided with a latch hook 22. The longitudinal beam connector 2 is provided with an electrical connection socket 23. The crossbeam connector 1 is provided with a positioning post 11 that matches the positioning hole 21. The outer side of the crossbeam connector 1 is provided with a self-locking latch 12. The buckle of the self-locking latch 12 is detachably connected to the latch hook 22. The crossbeam connector 1 is provided with an electrical connection plug 13 that is electrically connected to the electrical connection socket 23. Specifically, in this embodiment, the crossbeam connector 1 and the longitudinal beam connector 2 are connected to the crossbeam 100 and the longitudinal beam 200 respectively by bolts or direct welding. The crossbeam 100 and the longitudinal beam 200 are spliced to form a T-shape, which can straddle the rails and travel along the rails for track inspection operations. Furthermore, to facilitate disassembly and transportation and ensure assembly accuracy, the longitudinal beam connector 2 is provided with several hollow positioning holes 21. During assembly, the positioning pins 11 on the crossbeam connector 2 can be inserted into the corresponding positioning holes 21 to complete the initial positioning and accuracy calibration. When the positioning pins 11 are inserted into the positioning holes 21, the insertion accuracy is completely corrected, so that the electrical connection socket 23 and the electrical connection plug 13 are aligned and inserted, thereby completing the electrical connection at the same time as the mechanical connection. As can be seen, the positioning post 11 lacks a locking structure after being inserted into the positioning hole 21. To prevent the positioning post 11 from detaching from the positioning hole 21, a self-locking latch 12 is installed on the outside of the crossbeam connector 1, and a latch connecting hook 22 is set on the outside of the longitudinal beam connector 1. By cooperating with the self-locking latch 12 and the latch connecting hook 22, the buckles of the self-locking latches 12 on both sides of the crossbeam connector 2 are opened outward, locking the crossbeam connector 1 and the longitudinal beam connector 2, thereby connecting the crossbeam 100 and the longitudinal beam 200 into one unit. When track replacement inspection and transport of the track inspection instrument are required, the operator only needs to reverse the operation to separate the crossbeam 100 and the longitudinal beam 200, making disassembly and transport extremely convenient. The applicant's designed split-type track inspection instrument does not require two people to carry it together and is easy to transport. In areas with poor working conditions, such as steep slopes, it can greatly reduce the potential safety hazards of collaborative transport. At the same time, the detachable structure also facilitates storage.
[0016] like Figures 1-3As shown, the positioning hole 21 includes a main positioning hole 211 and a secondary positioning hole 212, and the positioning post 11 includes a main positioning post 111 and a secondary positioning post 112. The main positioning post 111 is fitted into the main positioning hole 211, and the secondary positioning post 112 is fitted into the secondary positioning hole 212. Specifically, the main positioning post 111 and the secondary positioning post 112 on the crossbeam connector 1 are aligned with the main positioning hole 211 and the secondary positioning hole 212 on the longitudinal beam connector 2, and are slowly inserted into the holes. The double-hole fit improves assembly accuracy and ensures that the electrical connection performance meets the standards.
[0017] like Figures 1-3 As shown, the secondary positioning hole 212 and the secondary positioning post 112 adopt an elliptical structure, which ensures the positioning accuracy in both the horizontal and vertical directions when the crossbeam and the longitudinal beam are connected.
[0018] Specifically, the crossbeam connector 1 and the longitudinal beam connector 2 are made of stainless steel by milling, forming an integral piece with high structural strength.
[0019] like Figure 4 As shown, there are two auxiliary positioning holes 212, which are arranged on both sides of the main positioning hole 211. Together with the main positioning hole 211, they form a triangular positioning, which enhances the rigidity and stability of the connection, effectively prevents vibration and loosening and slight displacement of the track inspection instrument during its movement, and avoids electrical connection failure between the electrical connection socket 23 and the electrical connection plug 13.
[0020] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
