Description

Technical Field

[0001] This utility model belongs to the field of quick-release device technology, specifically, it relates to a quick-release structure for simulating a track and a detection device for axle counting equipment. Background Technology

[0002] Axle counters, also known as microcomputer axle counters, are devices installed at both ends of railway stations. They use closed-loop sensors installed on the rails to monitor the number of train wheelsets passing by. After being detected by a microcomputer system and gates located indoors, the wheelset count of the station is sent to the other station using semi-automatic equipment. When the train arrives at the other station, the station automatically opens the track when the received wheelset count matches that of the departure station. In other words, it is a railway signaling device that can detect passing wheels and can replace many ordinary track circuits.

[0003] Axle counting equipment is usually installed on steel rails. Before it is put into use, its working condition needs to be tested. Currently, most testing devices directly fix the axle counting equipment on simulated steel rails. If there is a malfunction in the working condition of the axle counting equipment, it is necessary to repeatedly disassemble and reassemble the axle counting equipment from the simulated steel rails for testing. The disassembly and reassembly process of the axle counting equipment takes a lot of time and is not conducive to the effective testing process.

[0004] Therefore, the technical solution of this utility model is proposed. Summary of the Invention

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 3 As shown in the illustration, this application provides a quick-release structure for simulating a track, such as... Figure 2 and Figure 3 As shown, the installation includes an installation opening 7 (preferably rectangular, but other shapes are also possible; the specific shape depends on the actual design and is not specifically limited) at the required installation location of the simulated track 2. An installation plate 8 is disposed within the installation opening 7, and the installation plate 8 is connected to a first guide plate and a second guide plate 9 on opposite sides along the first direction. The first guide plate and the second guide plate 9 are respectively slidable along the second direction, with the first direction perpendicular to the second direction (e.g., ...). Figure 2 As shown in the diagram); the first guide plate and the second guide plate 9 are respectively provided with a first elastic element and a second elastic element (both elastic elements are springs 14); the first limiting plate 16 and the second limiting plate are provided at the mounting opening 7, and the first limiting plate 16 and the second limiting plate are also located on opposite sides of the mounting plate 8 along the first direction, and can slide along the first direction to approach or move away from the mounting plate 8, wherein the first limiting plate 16 is connected to the first elastic element, the second limiting plate is connected to the second elastic element, and the first limiting plate 16, the first elastic element, the second limiting plate and the second elastic element work together to limit the position of the mounting plate in the mounting opening 7 along the first direction, so as to realize the installation along the first direction. The device includes a position limiter in one direction; it also includes a push-pull rod 11 (preferably a T-shaped structure for easy connection and push-pull operation; however, the push-pull rod 11 can also be other shapes, as long as it can satisfy the push-pull action; the specific shape is not limited in this technical solution). The push-pull rod 11 is connected to the mounting plate 8 and is set along the second direction. When the push-pull rod 11 is pushed, the push-pull rod 11 drives the mounting plate 8, the first guide plate, and the second guide plate 9 to slide along the second direction. When resetting, the push-pull rod 11 is used to limit the position of the mounting plate 8 in the second direction within the mounting opening 7, thereby achieving the position limit of the mounting plate 8 in the second direction within the mounting opening 7 during resetting.

[0033] When using this invention, if a malfunction is detected in the working state of the axle counting device 3, the two limiting plates can be pressed. The two limiting plates, in conjunction with the two elastic elements, move towards the mounting plate 8 in the first direction, allowing the two limiting plates to squeeze the two elastic elements until the mounting plate 8 is in a free state in the first direction within the mounting opening 7. Then, the push-pull rod 11 is pulled to move in the second direction. That is, the push-pull rod 11, in conjunction with the two mounting slots and the two guide plates, drives the mounting plate 8 to move within the mounting opening 7, allowing the mounting plate 8 to move the axle counting device 3 until it is removed from the mounting opening 7. This allows the axle counting device 3 to be quickly removed from the simulated track 2, and then the staff can check the working state of the axle counting device 3, facilitating its maintenance.

[0034] like Figure 2 and Figure 3 As shown in the figure, in order to realize the installation of the elastic element, the following specific structure can be adopted: the first guide plate is provided with a first movable cavity 12, the second guide plate 9 is provided with a second movable cavity, the first elastic element is provided in the first movable cavity 12, and the second elastic element is provided in the second movable cavity.

[0035] Furthermore, such as Figure 3 As shown, in order to achieve the connection between the limiting plate and the corresponding guide plate, the following specific connecting structure is preferred in this embodiment: a first snap-fit ​​block 13 is connected between the first limiting plate 16 and the corresponding first guide plate, and a second snap-fit ​​block is connected between the second limiting plate and the corresponding second guide plate 9.

[0036] One end of the first elastic member abuts against the inner wall of the first movable cavity 12, and the other end abuts against the first snap-fit ​​block 13;

[0037] One end of the second elastic element abuts against the inner wall of the second movable cavity, and the other end abuts against the second snap-fit ​​block.

[0038] Furthermore, specifically, such as Figure 3 As shown, a first locking groove 19 and a second locking groove are respectively provided on the first limiting plate 16 and the second limiting plate. One end of the first locking block 13 is located in the first locking groove 19, and the other end is inserted into the first movable cavity 12. One end of the second locking block is located in the second locking groove, and the other end is inserted into the second movable cavity.

[0039] like Figure 3 As shown, in order to guide the movement of the limiting plate and prevent deviation, as Figure 3As shown in the figure, in this embodiment, a movable guide structure is provided at the simulated track 2 corresponding to the first limiting plate 16 and the second limiting plate, respectively. The movable guide structure includes a movable groove 15, a guide groove 17 and a limiting guide block 18. The movable groove 15 and the guide groove 17 both extend along the first direction. The limiting guide block 18 is connected to the corresponding limiting plate and is slidably disposed on the guide groove 17.

[0040] Taking the compression of the first limiting plate 16 as an example, the first limiting plate 16 is displaced in the movable groove 15 along the first direction, while the limiting guide block 18 is driven to slide and guide along the first direction on the guide groove 17.

[0041] To guide the mounting plate 8 along the second direction, in this embodiment, as follows: Figure 2 As shown, a first mounting groove 10 and a second mounting groove extending in a second direction are provided in the mounting opening 7. A first guide plate is slidably disposed in the first mounting groove, and a second guide plate 9 is slidably disposed in the second mounting groove.

[0042] According to the second aspect of this application, such as Figure 1 As described above, this utility model provides a detection device for an axle counting device, including a base 1, a simulated track 2 arranged side by side on the base 1, a simulated wheel 4 disposed on the simulated track 2, an axle counting device 3, and a quick-release structure of the simulated track 3 as described above. The axle counting device 3 is disposed on the quick-release structure of the simulated track 2. When the simulated wheel 4 runs along the simulated track 2 and passes through the axle counting device 3, the required information of the passing simulated wheel 4 can be detected, and the required information can be transmitted to the control system to determine the working status of the axle counting device.

[0043] like Figure 1 As shown, it also includes a position sensor 6, which is connected to the control system and is used to detect the running position of the simulated wheel.

[0044] Understandably, a fixing plate 5 is provided on the base 1, and the position sensor 6 is located on the fixing plate 5.

[0045] In use, the train's operation can be simulated through the base 1, simulated track 2 (which can be simulated steel rail), simulated wheels 4, axle counting device 3 mounted on the mounting plate 8, and position sensor 6. The axle counting device 3 detects signals passing through the simulated wheels 4, monitoring the number of wheelsets passing. After detection by an indoor microcomputer system and a gate, the wheelset count of this station is sent to the other station using semi-automatic equipment. When the train arrives at the other station, the station automatically opens the section when the received wheelset count matches that of the departure station. This simulation process allows for the monitoring of the working status of the axle counting device 3. If the axle counting device 3 malfunctions, its quick-release mechanism on the simulated track 2 allows for rapid removal, enabling staff to inspect its operation. This facilitates maintenance, enabling rapid inspection and real-time monitoring of its working status, improving work efficiency and reliability, saving time, and enhancing practicality.
