Technical Field

[0001] This utility model belongs to the field of hook and tongue pin technology, specifically, it relates to a safety protection device for the hook and tongue pin of a rail vehicle. Background Technology

[0002] In steelmaking workshops, molten iron and other materials are mostly transported by rail vehicles. Currently, there is a risk of breakage in the "hook tongue pin" of rail-coupled vehicles. After breakage, the hook tongue pin will come out of the pin hole downwards, causing the hooks on both sides to detach, resulting in a hook detachment accident, which in turn can lead to traffic collisions, molten iron spillage and fire accidents, personal injury accidents, and locomotive derailment accidents.

[0003] Chinese patent CN216580518U discloses a safety protection device for the hook tongue pin of a rail-coupled vehicle. The device includes a mounting box fixed to the bottom surface of the hook tongue. A support plate located below the hook tongue pin is fixed to the outside of the mounting box. A transverse detection plate is hinged to the mounting box with the hinge axis arranged transversely. One end of the detection plate extends between the hook tongue pin and the support plate. A microswitch adapted to the other end of the detection plate is fixed inside the mounting box. A battery is installed inside the mounting box, and a horn is fixed to the lower end of the support plate. In the above-mentioned prior art, when the hook tongue pin breaks and needs replacement, the device needs to be disassembled, adjusted, and the hook tongue pin installed after the main body is fastened below the hook tongue. Then, the device needs to be fixed in its original position. The overall operation is complex and slow, and not fast or effective enough.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a safety protection device for the hook tongue pin of a rail vehicle, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A safety protection device for a rail vehicle hook tongue pin includes: a mounting ring, a housing, an inner housing, and a hook tongue pin. Mounting seats are uniformly fixedly connected to the outer top of the mounting ring. The inner wall of the housing has internal threads, and the outer wall of the inner housing has external threads. The inner housing is rotatably mounted inside the housing. A pad is provided on the top of the inner housing. A conductive copper sheet is horizontally arranged on the top of the pad. A fixing band is vertically arranged on the top of the pad, and the fixing band is positioned above the conductive copper sheet. The conductive copper sheet is folded into an L-shape, and a copper ring is provided on the top of the conductive copper sheet. The copper ring is fitted onto the hook tongue pin. A battery is provided on the inner side of the top of the inner housing, and a horn is provided on one side of the battery.

[0008] Optionally, the mounting ring has a claw opening between two mounting seats, a pressure block is provided with the claw opening facing outward, movable holes are provided on both sides of the pressure block, a spring post is sleeved in the movable hole, a spring is sleeved on the side wall of the pressure block and the claw opening, a hook is fixedly connected to the inner side of the outer shell at the claw opening, and a rotating shaft is provided on the outer side of the outer shell at the position opposite to the hook.

[0009] Optionally, the mounting ring has a viewing window located at the center of the jaw opening and the rotating shaft.

[0010] Optionally, a baffle is fixedly connected to the front section of the spring post inside the movable hole.

[0011] Optionally, a signal light is provided on the other side of the horn.

[0012] Optionally, a transparent cover is installed at the bottom of the inner shell.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] The safety protection device for the hook tongue pin of this rail vehicle is fixed to the hook tongue pin by fasteners through the mounting base. After opening the mounting ring and the outer shell, the copper ring is put on the hook tongue pin, and then the hook is fastened. By observing through the viewing window and rotating the inner shell, a certain distance is maintained between the bottom of the hook tongue pin and the conductive copper plate. When the hook tongue pin breaks, the hook tongue pin moves downward and the bottom contacts the conductive copper plate and the copper ring to form a current closed loop. The battery-powered horn alarm is activated. The operator only needs to press the pressure block to open the inner shell adjustment device, replace the hook tongue pin, and finally put the copper ring back on and repeat the previous operation. When replacing the hook tongue pin, there is no need to remove the entire device, which shortens the overall replacement time and improves work efficiency.

[0015] The safety protection device for the hook tongue pin of this rail vehicle adds a signal light to the battery line. When the hook tongue pin triggers the connection of the line, it not only emits a sound through the horn, but the signal light also flashes at the same time. The operator can observe the flashing area through the transparent cover, so as to quickly locate the location and make it convenient to use in relatively dark areas.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-6 As shown in the figure, this embodiment provides a safety protection device for a rail vehicle hook tongue pin, including...

[0029] like Figures 1 to 4As shown, in this embodiment, mounting bases 101 are uniformly fixedly connected to the outer side of the top of the mounting ring 1. The inner wall of the outer shell 2 has internal threads, and the outer wall of the inner shell 3 has external threads. The inner shell 3 is rotatably installed inside the outer shell 2. A pad 301 is provided on the top of the inner shell 3. A conductive copper sheet 302 is horizontally arranged on the top of the pad 301. A fixing strap 304 is vertically arranged on the top of the pad 301. The fixing strap 304 is positioned above the conductive copper sheet 302. The conductive copper sheet 302 is folded into an L-shape. A copper ring 303 is provided on the top of the conductive copper sheet 302. The copper ring 303 is fitted onto the hook pin 4. A battery 306 is provided on the inner side of the top of the inner shell 3. A horn 307 is provided on one side of the battery 306. The fixing strap 304 is made of non-conductive material to fix the conductive copper sheet 302 to the pad 301. Rotating the inner shell 3 can change the distance between the pad 301 and the top of the mounting ring 1. This shortens the distance between the bottom of the hook pin 4 and the conductive copper sheet 302, ensuring that when the bottom of the hook pin 4 breaks and contacts the conductive copper sheet 302, the pad 301 can support the hook pin 4 to prevent the broken part from falling. The broken part can still play a connecting role. This distance cannot be too long, otherwise the hook pin 4 will fall directly out of the pin hole when it breaks. Similarly, it cannot be too far to avoid accidental contact. When the broken part contacts the hook pin 4, the upper end of the hook pin 4 is fitted with a copper ring 303, and the lower end contacts the conductive copper sheet 302. The three form a current closed loop, which is then powered by an external battery 306. The current connects to the speaker 307 to make it work and produce sound, reminding the staff to replace the hook pin 4. The battery 306, speaker 307, conductive copper sheet 302, and copper ring 303 form a single circuit. When the hook pin 4 contacts the conductive copper sheet 302, the circuit is connected.

[0030] like Figure 1 , 3As shown in Figures 5 and 6, in this embodiment, the mounting ring 1 has a claw opening 102 between two mounting seats 101. A pressure block 103 is provided outward from the claw opening 102. Movable holes 105 are provided on both sides of the pressure block 103. A spring post 104 is sleeved in the movable hole 105. A spring 107 is sleeved on the side wall of the spring post 104 at the pressure block 103 and the claw opening 102. A hook 202 is fixedly connected to the inner side of the outer shell 2 at the claw opening 102. A rotating shaft 201 is provided on the outer side of the outer shell 2 at a position opposite to the hook 202. The mounting ring 1 and the outer shell 2 are connected on one side by hanging on the claw opening 102 through the hook 202, and on the other side by two extension blocks passing through the rotating shaft 201. The two can rotate around the pivot 201. The hook 202 is fixed by being hooked at the claw opening 102. By pressing the pressure block 103 inward from the outside, the spring column 104 extends into the movable hole 105 to squeeze the outer spring. The pressure block 103 pushes the hook 202 inward, thereby squeezing the hook 202 away from the claw opening 102. The mounting ring 1 and the outer shell 2 can then be opened. Even if the mounting ring 1 is fixed below the hook tongue pin 4, and the operator cannot adjust the device inward from the mounting ring 1, the mounting ring 1 and the outer shell 2 can be separated. The hook 202 is made of a material with localized extensibility and can be repeatedly bent. After adjustment, the hook 202 can be pushed back into the claw opening 102 to lock.

[0031] like Figures 1 to 3 As shown, in this embodiment, the mounting ring 1 has a viewing window 108 at the center of the claw opening 102 and the rotating shaft 201. The viewing window 108 is made of transparent material, allowing the interior to be observed from the outside. During installation, the inner shell 3 needs to be rotated to push the pad 301 up, shortening the distance between the conductive copper sheet 302 and the hook pin 4. At this time, it is necessary to manually judge whether the distance is reasonable through the viewing window 108 to avoid adverse consequences caused by being too close or too far.

[0032] like Figure 5 , 6 As shown, in this embodiment, a baffle 106 is fixedly connected to the front part of the spring post 104 inside the movable hole 105. The movable hole 105 is divided into two ends. The end closer to the spring 107 is narrower, and its inner diameter is the same as that of the spring post 104. The end further away from the spring 107 is wider, and its inner diameter is the same as that of the baffle 106. The baffle 106 is used to lock the movable hole 105 to prevent the pressure block 103 from popping out from the claw opening 102.

[0033] like Figure 4 As shown, a signal light 305 is provided on the other side of the speaker 307 in this embodiment; wherein, by adding a signal light 305 to the battery circuit, when the hook pin triggers the circuit connection, not only can sound be emitted through the speaker 307, but the signal light 305 can also flash at the same time, which can quickly locate the position and is convenient for use in relatively dark areas.

[0034] like Figure 4 As shown, a transparent cover is installed at the bottom of the inner shell 3 in this embodiment; the transparent cover is necessary to protect the internal battery 306, horn 307 and signal light 305, and the signal light 305 can emit light through the transparent cover to remind the staff.

[0035] Example 1

[0036] In this embodiment, the device is fixed to the hook pin 4 by passing the fastener through the mounting base 101. During installation, ensure that the hook pin 4 is aligned with the center of the pad 301. Press the pressure block 103 to open the mounting ring 1 and the outer shell 2, and put the copper ring 303 on the hook pin 4. Then fasten the hook 202. By observing the viewing window 108 and rotating the inner shell 3, a certain distance is maintained between the bottom of the hook pin 4 and the conductive copper sheet 302. When the hook pin 4 breaks, it moves downward and the bottom contacts the conductive copper sheet 302 and the copper ring 303 to form a current closed loop. The battery 306 powers the horn 307 to alarm. The operator only needs to press the pressure block 103 to open the inner shell 3 to adjust the device, replace the hook pin 4, and finally put the copper ring 303 back on and repeat the previous operation.

[0037] Example 2

[0038] In this embodiment, when the hook pin 4 breaks and triggers the alarm, the entire circuit will also activate the indicator light 305, which can emit light through the transparent cover and, together with the speaker 307, allow the operator to quickly locate the position, making it suitable for use in dim environments.
