Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Please refer to Figure 1 The embodiments of the present invention relate to a multi-purpose emergency response tool for high-speed trains, comprising:

[0029] (1) Crowbar Module 12

[0030] The crowbar body 3 is cylindrical with an external thread at one end. The cylindrical shape facilitates gripping, and the external thread allows for rotational connection with the internal threaded clamp on the connecting rod module 13, enabling modular assembly. This facilitates tool storage and carrying, and ensures the overall structural stability after connection. It is made of alloy steel, such as 40Cr alloy steel. This alloy steel, after tempering, possesses high strength and toughness, capable of withstanding significant prying forces without easily breaking. When performing operations such as hook and tongue adjustments, significant force needs to be applied to components like the transition coupler; the 40Cr alloy steel crowbar body meets this requirement, ensuring operational effectiveness and safety. The reflective markings 2 on its surface are made of reflective film material. This material has high reflectivity and good weather resistance, maintaining good reflectivity under various harsh weather conditions (such as strong sunlight, rain erosion, and low-temperature freezing), improving the crowbar's visibility in the working environment and reducing the risk of accidents caused by accidental contact with the crowbar.

[0031] Crowbar head 1: Made of tool steel, such as T8 tool steel, and hardened and tempered to achieve a high level of hardness, it is flat and sharp. Its length is no less than 5cm and its width no less than 2cm. This shape and size design is based on the actual needs of the hook tongue coupling and adjustment operation. The flat crowbar head allows for better contact with the hook tongue, distributing the prying force evenly and reducing localized damage to the hook tongue; the sharp point facilitates insertion into the gap between the hook tongue and other components, precisely applying prying force to complete the coupling operation of the transition coupler.

[0032] (2) Linkage integral module 13

[0033] Link 8: The main body is cylindrical, with a length of not less than 25cm and a diameter of not less than 2cm. Sufficient length and diameter ensure that link 8 has sufficient strength and stability when subjected to various operating forces, and will not easily bend or break. Both ends are equipped with internal threaded clamps for connecting the pry bar module 12 and the adjustable wrench head module 14, making the entire tool an organic whole, reducing the number of tools, and making it easy to carry and operate.

[0034] Ratchet 4: Located at one end of connecting rod 8, it is equipped with an 18mm ratchet sleeve 41 and a 24mm ratchet sleeve 42. These two sleeve sizes are designed based on the dimensions of components commonly found on high-speed trains that require ratchet tools for operation. For example, in manual opening / closing of the hood and manual engagement / disengagement of the electric hook, they correspond to the dimensions of the hexagonal unlocking stud at the bottom of the hood and the manual unlocking bolt of the electric hook, respectively, ensuring precise engagement with these components and achieving efficient unlocking operations. A ratchet selector switch 6 is located on the right side of ratchet 4, allowing operators to quickly switch between different sleeve sizes according to actual needs, improving operational efficiency.

[0035] Tool scale 9: Located in the center of the front of the main body of connecting rod 8, with a length of not less than 50mm and not more than 90mm, and both ends of it being at least 10mm away from the first anti-slip rubber sleeve 7 and the second anti-slip rubber sleeve 11. Please refer to... Figure 2The scale of the tool ruler 9 is arranged circumferentially (e.g., using a ring-shaped scale line; the circumferential arrangement of the scale lines ensures that the scale can closely adhere to the object being measured, improving measurement accuracy). This includes main scale lines 91 and secondary scale lines 92. The main scale line 91 is made by embedding metal wire (such as stainless steel wire), with the wire being wider than the secondary scale line 92. This ensures the main scale line is highly visible and also improves legibility under different lighting conditions through the luster of the metal wire. The main scale line is coated with reflective paint; the selected reflective paint has a high reflectivity and good adhesion, ensuring clear display of the scale even in low-light working environments, such as at night or during emergency situations in tunnels, facilitating operator reading. The scale is arranged in a ring shape circumferentially, and a special injection molding process ensures that the scale lines closely adhere to the object being measured, improving measurement accuracy.

[0036] Lighting Device 14: Utilizing high-brightness, low-power LED chips as the light source, LED chips offer advantages such as long lifespan and strong shock resistance, making them suitable for use in complex and variable environments like emergency response. The power supply can be a rechargeable lithium battery, which boasts high energy density and low self-discharge rate, providing sustained power support for the lighting device. The housing of the lighting device is made of transparent polycarbonate, a material with excellent optical properties that effectively and evenly scatters the light emitted by the LED chips, while also possessing high strength and impact resistance to protect the internal chips and circuitry from external damage.

[0037] The first anti-slip rubber sleeve 7 and the second anti-slip rubber sleeve 11 are located at the left and right ends of the scale 9, respectively, with a length of not less than 7cm. They have anti-slip textures on the surface and are made of high-friction and insulating materials. The anti-slip textures and high-friction materials effectively increase the friction between the operator's hand and the connecting rod 8, preventing the tool from slipping during operation and ensuring operational safety. The use of insulating materials is due to the large number of electrical devices on the high-speed train; during operation, there may be contact with live parts or exposure to an electrical environment. Insulating materials prevent electric shock accidents caused by the tool's conductivity.

[0038] (3) Adjustable wrench head module 10

[0039] The main body (adjustable wrench structure) has an external thread at one end that rotates to connect with the internal threaded clamp on the connecting rod module 13, integrating it with the entire tool. It is made of chromium-molybdenum steel, which possesses high strength, high heat resistance, and good fatigue resistance. In operations such as emergency brake pad removal, the adjustable wrench is needed to frequently adjust the hexagonal reset bolt of the brake caliper. The chromium-molybdenum steel can withstand repeated stress over long periods without deformation or damage, ensuring smooth operation. Its maximum opening is no less than 36mm. This size design is based on the specifications of common bolts on components such as EMU brake calipers, meeting operational needs in most situations and ensuring the versatility of the adjustable wrench in emergency response tasks.

[0040] Hanging Ring 15: The hanging ring is designed in a circular or oval shape with a smooth surface, facilitating connection to ropes or poles, hooks, etc., at the work site. During emergency response, the hanging ring can be attached to poles or hooks at the work site for temporary tool placement, preventing tools from being damaged or lost due to careless placement on the ground or other locations. Alternatively, a rope can be tied to the hanging ring and attached to the worker, ensuring the adjustable wrench head module remains connected to the operator, preventing tools from falling due to large movements or unexpected situations during operation, ensuring tools are always available, and improving the efficiency and reliability of emergency response.

[0041] In a preferred embodiment of this tool, its application in emergency response tasks on high-speed trains is as follows:

[0042] (1) Manually opening / closing the hood task

[0043] Upon arriving at the driver's cab at the coupling end of the EMU, the operator first confirms that the [Interlock Control] circuit breaker is in the off state to prevent accidental power connection. Then, the operator closes the "Divide and Merge" butterfly valve in the driver's cab at the coupling end, cutting off the relevant air or hydraulic circuits to create a safe and stable environment for hood operation.

[0044] Take out the multi-purpose emergency handling tool for high-speed trains of this invention, and rotate the 18mm ratchet sleeve 41 at one end of the connecting rod integral module 13 onto the hexagonal unlocking stud at the bottom of the hood. The operator holds the connecting rod 8 and rotates the tool according to the direction of opening or closing the hood. At this time, the ratchet mechanism makes the operation more convenient and efficient. During the rotation, the torque transmitted by the tool acts on the unlocking stud, causing the locking mechanism of the hood to gradually unlock. After unlocking, the hood can be manually opened or closed.

[0045] (2) Manual connection / disconnection of electric hooks

[0046] The operator enters the driver's cab at the coupling end, first confirms that the [Connection Control] circuit breaker is off, then closes the "electric hook" shut-off valve to ensure that the air or hydraulic circuits related to the electric hook are cut off and that the electrical system is in a safe state.

[0047] Pick up the multi-purpose tool of this invention and place the 24mm ratchet sleeve 42 on the connecting rod module 13 onto the manual unlocking bolt of the electric hook. After switching to the 24mm sleeve via the ratchet changer switch 6, the operator rotates the tool in the direction of electric hook engagement / disengagement. The torque generated by the tool acts on the unlocking bolt, driving the engagement / disengagement mechanism inside the electric hook to move.

[0048] (3) Adjusting the task of hook tongue connection

[0049] When it is found that the transition coupler tongue is not properly engaged, that is, the red line pointer at the tongue is not aligned, the operator should first try the conventional re-uncoupling and pressing down of the transition coupler. If this is ineffective, the following operation should be performed.

[0050] The operator holds the emergency response multi-purpose tool of this invention and places the pry bar head 1 of the pry bar module 12 at the hook tongue. Based on the actual position of the hook tongue and the coupling requirements, the operator precisely applies force to the hook tongue using the flat, pointed design of the pry bar head 1. During operation, the lever principle is used to push the hook tongue to adjust its position until the transition coupler is fully engaged, ensuring the hook tongue is in the correct coupling position and guaranteeing the reliability of the connection between vehicles.

[0051] (4) Emergency brake pad removal task

[0052] When emergency removal of the brake pads is required, the operator first uses the adjustable wrench head module 10 of the tool of this invention. The opening of the adjustable wrench 10 is adjusted to 36mm to tightly lock the hexagonal reset bolt of the brake caliper.

[0053] The operator rotates the adjustable wrench 10 clockwise to adjust the hexagonal reset bolt of the brake caliper. The operator gradually moves the brake caliper arm to its maximum open position, increasing the clearance between the brake pads and the brake disc. In severe weather conditions such as ice, snow, or freezing rain, if adjusting with the adjustable wrench 10 alone is insufficient to achieve the desired clearance, the operator can further utilize the pry bar module 12. Inserting the pry bar into the appropriate position and using it to pry assist in adjusting the clearance between the brake pads and the brake disc, facilitates the removal of the brake pads, and ensures the smooth progress of brake system maintenance and repair work.

[0054] (5) Task of measuring the height difference between the coupler centerlines during EMU rescue.

[0055] The operator uses the tool scale 9 of the combination tool to measure the height difference between the center lines of the transition couplers. One end of the tool scale is aligned with a reference point on the coupler center line, and the other end is observed corresponding to the scale value on the other coupler center line. During measurement, it is essential to ensure the tool scale is perpendicular to the coupler center line. The height difference value is read according to the scale lines, and it is determined whether it does not exceed 50mm to prevent decoupling. In low-light environments, the reflective paint on the main scale lines makes the scale easier to read, and the lighting device 14 can also provide auxiliary lighting to ensure measurement accuracy.

[0056] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
