Description

Technical Field

[0001] This utility model relates to the field of emergency response technology for couplers, specifically to an emergency response tool for adjusting the height of couplers. Background Technology

[0002] The coupler difference refers to the height difference between the center lines of two adjacent couplers. According to railway safety standards, the coupler difference for trains other than high-speed trains must not exceed 75mm. This seemingly simple value is a key indicator for ensuring railway transportation safety. When the coupler difference exceeds the specified range, uneven stress on the couplers can occur during train operation, especially during starting, braking, or passing through curves, potentially leading to serious accidents such as coupler breakage or decoupling.

[0003] Currently, in response to the above situation, conventional trains widely use emergency response devices. When the coupler difference exceeds the limit during train operation, the train crew usually uses a crowbar or oil pick to carry out emergency response. However, this method has a low safety factor and is inconvenient to operate. The emergency response time is about 15-20 minutes on average. If the on-site working conditions are limited, the difficulty of handling will increase, the time will be longer, and it may even exceed the station stop time, thus delaying the train's on-time operation.

[0004] To address this issue, we designed an emergency tooling system for adjusting the coupler height. Utility Model Content

[0005] This utility model provides an emergency tooling for adjusting the height of a train coupler. By using a push rod and a support seat together, it can be quickly assembled and the height of the coupler can be quickly adjusted, solving the problems of increased processing difficulty and long processing time mentioned in the background art.

[0006] This utility model provides the following technical solution: An emergency handling fixture for adjusting the height of a train coupler includes a support member and a push rod. The support member has a top head and a drive unit for driving the top head to rise and fall. One end of the push rod is detachably connected to the top head. A support seat is provided at the other end of the push rod.

Detailed Implementation

[0018] 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.

[0019] The coupler difference refers to the height difference between the center lines of two adjacent couplers. According to railway safety standards, the coupler difference for trains other than high-speed trains must not exceed 75mm. This seemingly simple value is a key indicator for ensuring railway transportation safety. When the coupler difference exceeds the specified range, uneven stress on the couplers can occur during train operation, especially during starting, braking, or passing through curves, potentially leading to serious accidents such as coupler breakage or decoupling. To address this, conventional trains widely use emergency response devices. When the coupler difference exceeds the limit during train operation, train crew members typically use crowbars or hydraulic picks for emergency response, but these methods are ineffective.

[0020] Example: Reference Figures 1-3This utility model provides an emergency handling tool for adjusting the height of a vehicle coupler. Its basic components mainly include a jack 102, a base 101 at the bottom of the jack 102, and a lifting head 600 connected to the jack 102 via a hydraulic drive structure 103. A hydraulic roller is also provided, which is used to press the hydraulic drive structure 103 on the jack 102. By applying pressure to the hydraulic drive structure 103 through the hydraulic roller, the lifting operation of the lifting head 600 can be realized. In actual use, the vehicle crew can easily adjust the height of the jack 102's top head 600 by simply operating the hydraulic roller. The hydraulic drive structure 103 includes a hydraulic pump, hydraulic lines, and a hydraulic control valve. The hydraulic pump is mounted on the base 101 and connected to the jack 102 via the hydraulic lines. The hydraulic control valve is installed on the hydraulic lines to control the flow direction and flow rate of the hydraulic oil, thereby controlling the lifting height of the top head 600. An anti-slip pad is also provided at the bottom of the base 101. The anti-slip pad is made of rubber material with a high coefficient of friction to increase the friction between the tooling and the ground, preventing the tooling from sliding during the adjustment of the coupler height and ensuring operational safety.

[0021] Specifically, a connecting rod 201 is also provided, and a sleeve 202 is provided at one end of the connecting rod 201. The sleeve 202 is detachably connected to the top head 600 of the support member 100, forming a top rod 200. The sleeve 202 can be fitted onto the top head 600. When it is necessary to adjust the height of the coupler, the sleeve 202 is fitted onto the top head 600. Due to the presence of the connecting rod 201, the operator can assist in the adjustment operation by fitting the connecting rod 201. The support seat 300 is fixedly connected to the other end of the connecting rod 201. The support seat 300 has a support surface, and at least six sets of limiting members are provided on the support surface. A clamping space 700 is formed between two adjacent sets of limiting members, which are two sets of transverse clamping plates 301 and four sets of oblique clamping plates 302.

[0022] Two sets of horizontal clamping plates 301 are arranged in parallel to limit and fix the coupler components at the bottom of the coupler from the horizontal direction, ensuring that the coupler components will not shift in the horizontal direction during the adjustment of the coupler height. Four sets of oblique clamping plates 302 are arranged in pairs on both sides of the horizontal clamping plates 301 and at a certain angle to the horizontal clamping plates 301. The oblique clamping plates 302 can clamp the coupler components from an oblique position, further enhancing the fixing effect of the coupler components and preventing them from shaking or shifting during the adjustment process, thus ensuring the stability and accuracy of the coupler height adjustment.

[0023] In the above scheme, the overall length of the top rod 200 is 745mm, and the length of the support base 300 is 200mm, the width is 80mm, and the thickness is 8mm. The top rod 200 is made of high-strength alloy steel and undergoes a special heat treatment process, possessing sufficient strength and rigidity to withstand significant forces without deformation during coupler height adjustment. The support base 300 is made of high-quality carbon steel, and its surface limiting components, including the transverse clamping plate 301 and the oblique clamping plate 302, are precision-machined with smooth, burr-free surfaces to ensure no damage is caused to the coupler components upon contact. During installation and use, the jack 102 is first fixed in a suitable position, then the sleeve 202 is placed on the top head 600. Next, the support base 300 supports the coupler components, causing the bottom of the coupler to fall into the clamping space 700. Through the combined action of the transverse clamping plate 301 and the oblique clamping plate 302, the coupler components are securely fixed, thus facilitating coupler height adjustment.

[0024] Reference Figure 4 and Figure 5 To improve the effectiveness of the above-mentioned device, a support component 500 and a storage box 400 made of stainless steel are also provided. The support component 500 consists of a support pad 501, a tray 502 and a rubber pad 503 made of silicone. The storage box 400 forms a storage space. The storage box 400 is hinged to a box cover 402. A locking plate 403 is rotatably installed on the box cover 402. A locking ring 404 is provided on the storage box 400. The locking plate 403 and the locking ring 404 are compatible. Handles 401 are provided on both sides of the storage box 400. The surface of the handles 401 is treated with anti-slip material to facilitate the handling and movement of the storage box 400 by the staff.

[0025] The bearing pad 501 has good flexibility and elasticity. The bearing pad 501 provides a stable support plane for the pallet 502. A rubber pad 503 is installed inside the pallet 502, and then the base 101 at the bottom of the jack 102 is placed on the rubber pad 503 to further increase the friction and prevent the coupler components from sliding during the adjustment process.

[0026] Specifically, the rubber pad 503 is 700mm long, 200mm wide, and 50mm high; the tray 502 is 708mm long, 208mm wide, and 20mm high; the bearing pad 501 has the same length and width as the rubber pad 503, but is 5mm thick; the storage box 400 is 850mm long, 250mm wide, and 250mm high; the lid 402 has an overall height of 20mm; and the base 101 is 60mm long, 60mm wide, and 10mm high.

[0027] When the storage box 400 is not in use, the lock plate 403 can be rotated to engage with the lock ring 404 to achieve a tight seal between the lid 402 and the storage box 400, preventing internal items from falling out or being affected by the external environment. The support member 100, top rod 200 and bearing member 500 can be disassembled and stored in the storage box 400 for easy access at any time.

[0028] When needed, simply open the cover 402, remove the support 100, top rod 200, and load-bearing component 500 from the storage box 400, and quickly assemble them according to the corresponding assembly steps. They can then be reused for coupler height adjustment work. Furthermore, because the storage box 400 is made of stainless steel, it has excellent corrosion resistance and durability, ensuring that the stored components are not affected by moisture, corrosion, or other environmental factors, effectively extending the service life of the entire emergency response tooling. At the same time, the reasonable size design of the storage box 400 provides sufficient storage space, allowing all components to be arranged orderly during storage, avoiding collisions and damage between components.

[0029] When a train experiences a coupler mismatch during operation, train crew members typically use crowbars or hydraulic picks for emergency response. This method is unsafe, inconvenient to operate, and takes an average of about 15 minutes. If on-site conditions are limited, it becomes difficult to handle and takes even longer, potentially exceeding the station stop time and delaying the train's on-time operation. This new device can be directly equipped and used to replace the original methods, reducing the average response time to about 3-5 minutes. It effectively shortens the emergency response time, improves operational efficiency, and eliminates the risk of affecting on-time train operation.

[0030] Secondly, when the coupler buffer block falls off, this device can also be used in conjunction with other emergency spare parts to quickly reset the coupler buffer block and quickly bind the buffer block to eliminate the risk of the parts falling off.

[0031] Finally, the dimensions of each part of this utility model were customized based on on-site measurements. The entire component can be disassembled and stored in a customized portable stainless steel storage box 400, making it convenient and quick to access and use. This improves the efficiency of emergency response. Train crew members do not need to frequently get on and off the train to retrieve materials during emergency response; they only need to retrieve the tool once, and one person can complete the emergency response, improving the efficiency of fault handling and effectively avoiding delays in train operation due to excessive emergency response time. It is also convenient for fixed-location storage and management. It can be used for emergency response when the train experiences a mismatch in coupling or when the coupler block falls off, reducing the time consumed during emergency response and improving the efficiency of emergency response.

[0032] Components not described in detail in this article are existing technologies.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
