Description

Technical Field

[0001] This utility model relates to the field of inspection instrument technology, specifically to a coupler support seat jamming inspection instrument. Background Technology

[0002] Coupler support jamming is one of the possible faults in railway vehicle operation. The inspection process needs to be meticulous and comprehensive to ensure safe operation.

[0003] The inspection method is generally the jack inspection method: Before the coupler is assembled, place a jack between the upper surface of the support seat and the impact seat, operate the jack to press down the support seat, the support seat should move down a distance of not less than 30mm, and the support seat should be able to return to its original position after the jack is removed; this method requires disassembling the coupler assembly to check for support seat jamming, which is labor-intensive and difficult to implement.

[0004] Another method is manual inspection: After the coupler is assembled, use a crowbar about 2m long. Insert one end of the crowbar into the gap between the coupler and the impact seat along the longitudinal direction of the car body. Manually press down the other end of the crowbar, pressing down the upper part of the coupler head, causing the coupler head and the support seat to move down. The support seat should move down a distance of not less than 10mm. After the crowbar is removed, the support seat should be able to return to its original position. This method requires two people to operate at the same time. One person is responsible for pressing down the coupler, and the other person is responsible for checking the pressing distance to confirm whether there is any jamming. This method is relatively labor-intensive. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing inspection methods typically involve disassembling the vehicle hook using a jack, which is labor-intensive; and manual methods, which use a pry bar to press down the hook head, require two people to work together to check the downward movement distance and confirm that the hook is stuck, which is also labor-intensive.

[0006] To solve the above problems, the technical solution adopted by this utility model is a coupler support seat jamming inspection instrument, including a housing, a protruding structure at one end of the housing, a slot on the lower side of the housing, an adjustable fixing structure in the slot, a connecting shaft fixed inside the slot, a connecting block rotatably mounted on the outside of the connecting shaft, a limit groove on the lower side of the connecting block, a strong magnet connected in the limit groove, an anti-slip pad on the outside of the connecting shaft at one end of the connecting block, a threaded hole on one side of the housing, a threaded fastening rod rotatably connected in the threaded hole, one end of the threaded fastening rod abutting against one side of the connecting block, a distance detection port on the lower side of the protruding structure, an indicator light embedded in one end of the housing, a charging port on one end of the housing, a button on the upper side of the housing, and a proximity switch on one side of the housing.

[0007] As a further embodiment of this utility model: a distance sensor is provided inside the housing at the distance detection port for detecting the downward pressing distance of the coupler.

[0008] As a further embodiment of this utility model: the indicator light is set to red and blue. The red light flashes rapidly to indicate that the instrument has started working and is reading the initial distance value. After successful reading, the blue light flashes rapidly. Then the coupler is pressed down. When the instrument detects a distance change of more than 10 mm, the blue light stays on. If the 10 mm change test is not completed, the red light will flash slowly after resetting, and the test can continue. After the 10 mm change test is completed, the coupler returns to the initial position, and the red light flashes slowly.

[0009] As a further solution of this utility model: the charging port is a Type-C interface. The advantages of using a Type-C interface are that it can be plugged in either direction without distinguishing the orientation, which improves the convenience of use; it supports high-speed data transmission and can quickly transfer large files; it has high-power charging capability to meet the fast charging needs of multiple devices; it is compatible with multiple protocols to achieve multi-functional integration; and it is highly durable with a long plug-in life.

[0010] As a further aspect of this invention, a rechargeable battery is provided inside the housing to facilitate power supply to the internal electronic components of the instrument.

[0011] As a further aspect of this invention, the length of the connecting block is less than the length of the connecting shaft, which facilitates the rotation of the connecting block.

[0012] As a further embodiment of this utility model: a knob is fixed at one end of the threaded fastening rod to facilitate rotation of the threaded fastening rod.

[0013] Compared with the prior art, the advantages of this utility model are as follows: This application adds a detection instrument, so when checking the coupler support seat jamming, only one person is needed to press down the coupler. The detection instrument is used to judge the pressing distance and the reset status, which saves manpower and simplifies the inspection operation. Attached Figure Description

[0020] 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 protection scope of the present utility model.

[0021] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0022] Combined with appendix Figure 1-3It can be seen that the device includes a housing 7, which houses a rechargeable battery to power the internal electronic components. One end of the housing 7 has a protruding structure. A slot 7.1 is formed on the lower side of the housing 7's interior, containing an adjustable fixing structure. This adjustable fixing structure includes a connecting shaft 8 fixed inside the slot 7.1, and a connecting block 9 rotatably mounted on the outside of the connecting shaft 8. The length of the connecting block 9 is less than the length of the connecting shaft 8 to facilitate rotation. A limit groove is formed on the lower side of the connecting block 9, in which a strong magnet 6 is connected. An anti-slip pad 10 is provided on the outside of the connecting shaft 8 at one end of the connecting block 9. A threaded hole 7.2 is formed on one side of the housing 7, in which a threaded fastening rod 11 is rotatably connected. One end of the threaded fastening rod 11 abuts against one side of the connecting block 9, and a knob is fixed to one end of the threaded fastening rod for easy rotation. A distance detection port 3 is located below the protruding structure, and a distance sensor is located inside the housing 7 at the distance detection port 3. Used to detect the depressing distance of the coupler, one end of the housing 7 is equipped with an indicator light 1, which is set to red and blue. The red light flashes rapidly to indicate that the instrument has started working and is reading the initial distance value. After successful reading, the blue light flashes rapidly and then the coupler is depressed. When the instrument detects a distance change of more than 10 mm, the blue light stays on. If the 10 mm change test is not completed, the red light will flash slowly after resetting, and the test can continue. After the 10 mm change test is completed, the coupler returns to the initial position and the red light flashes slowly. One end of the housing 7 has a charging port 2, which is a Type-C interface. The advantages of using a Type-C interface are that it can be plugged in either direction without distinguishing the direction, which improves the convenience of use; it supports high-speed data transmission and can quickly transfer large files; it has high-power charging capability to meet the fast charging needs of multiple devices; it is compatible with multiple protocols to achieve multi-functional integration; and it is durable and has a long plug-and-play life. There is a button 4 on the upper side of the housing 7 and a proximity switch 5 on one side of the housing 7. When it approaches the carriage, it will activate the instrument.

[0023] The working principle of this application is as follows: When conducting the test, the device is first placed on the top of the coupler support. If the top of the support is a sloping structure, the threaded fastening rod 11 can be loosened first to make the connecting block 9 loose. Then, the strong magnet 6 is attracted to the top of the support. Then, the housing 7 is rotated to make it horizontal so as to make accurate distance detection. Then, the threaded fastening rod 11 is rotated so that one end of it presses against one side of the connecting block 9 so as to fix the position of the housing 7 for subsequent testing.

[0024] Then, align the distance detection port 3 with the coupler. When the proximity switch 5 approaches the carriage, the instrument will be activated, and the red light will flash rapidly as the instrument begins to work, reading the initial distance value. After a successful reading, the blue light will flash rapidly. Then, a single person can use a crowbar, inserting one end into the gap between the structure and the support base, and then press the coupler down using the lever principle. When the instrument detects a distance change of more than 10 mm, the blue light will remain on. If the 10 mm change test is not completed, the red light will flash slowly after resetting, and the test can continue. After the 10 mm change test is completed, the coupler will return to its initial position, and the red light will flash slowly. There is no need to add another observer for visual inspection, saving manpower.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
