Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway rail breakage reinforcement technology, and in particular to an emergency rail breakage treatment device. Background Technology
[0002] With the continuous increase in railway speed, transport volume, and operating mileage in my country, the high-density and smooth railway transportation places higher demands on the emergency handling of track breakages. Quality defects in rails caused by production and transportation accidents, poor weld quality, and low maintenance quality can lead to rail breakage accidents. To improve the efficiency of emergency rail breakage response, reduce the impact of emergency response on railway transportation, and fill the technological gap of not being able to install emergency rescue devices for first aid after a main rail breakage at a turnout point, a comprehensive emergency rail breakage rescue device has been developed to address the difficulties in emergency rail breakage response in railway engineering.
[0003] Currently, if a rail break occurs on a straight or curved track, a standard rail emergency repair device can be used, allowing trains to proceed at a reduced speed. A maintenance window can then be requested for permanent repair (permanent repair refers to restoring the track's structure and function by inserting a short rail and welding it back on a damaged rail that has already undergone emergency or temporary repair). However, standard rail emergency repair devices require clamping and securing them to both sides of the stock rail. If the rail break occurs at a switch point, the break may be too large to install an emergency repair device due to the adjacent switch rail. In such cases, the train must be stopped for rail replacement and permanent repair before being allowed to proceed, significantly disrupting railway transport. Rail breaks at key switches or critical switch points on multi-directional railways pose a significant safety hazard due to the high volume and density of passenger and freight traffic, potentially escalating into an accident.
[0004] Therefore, in order to adapt to the installation of emergency rescue devices in various parts of the rail components, enhance emergency response efficiency, and improve safety redundancy, the development of an all-around emergency rescue device for rail breakage has become an urgent problem for technicians in this field. Utility Model Content
[0005] The purpose of this utility model is to provide an emergency rail breakage treatment device to solve the problem mentioned in the background art that the application scenarios of ordinary rail emergency rescue devices are limited and cannot be applied to rail breaks at the main rail of turnout switching points.
[0006] The present invention adopts the following technical solution:
[0007] This utility model discloses an emergency handling device for rail breakage, including a bridge plate. One side of the bridge plate is provided with a rail waist fitting part and a rail top fitting part. The rail waist fitting part fits with the rail waist of the base rail, and the rail top fitting part fits with the side of the rail top of the base rail.
[0008] The bridge deck has a portal opening in the middle along its length, and the portal opening is secured to the rail brace and the sleeper.
[0009] The bottom of the bridge plate is fixedly connected to the bottom of the base rail by multiple hook-lock components.
[0010] Preferably, a wheel contact surface is provided on the top surface of the bridge plate near the main rail, the wheel contact surface is inclined, and the wheel contact surface is in contact with the wheel.
[0011] Preferably, the hook lock assembly includes a hook lock bolt and a nut;
[0012] One end of the hook-lock bolt is hooked to the bottom of the rail on the side of the main rail away from the bridge plate, and the other end of the hook-lock bolt passes through the bottom of the bridge plate and is threadedly fastened to the nut.
[0013] Preferably, the bottom of the bridge plate is provided with a locking part, the locking part extends to the bottom of the basic rail, and the locking part is provided with a plurality of locking holes;
[0014] The hook bolt includes a threaded rod, one end of which is provided with a hook head, and the hook head is provided with a hook opening, which is engaged with the bottom of the rail on the side of the main rail away from the bridge plate.
[0015] The other end of the threaded rod passes through the locking hole and is threadedly fastened to the nut.
[0016] Preferably, the top surface of the hook head is lower than the top surface of the slide plate.
[0017] Preferably, the hook-lock assembly is symmetrically distributed on both sides of the sleeper.
[0018] Preferably, the gate opening is U-shaped, and the gate opening includes a rail support opening and a sleeper opening. The rail support opening is positioned on the outside of the rail support, and the sleeper opening is positioned on the outside of the sleeper.
[0019] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0020] This invention features a bridge plate that fits tightly against the side of the main rail, while the hook-locking bolts of the hook-locking assembly are located below the main rail, firmly hooking the bottom of the main rail to form a secure lock. This provides a solid support for the main rail from the bridge plate, solving the problem of difficult rail breakage handling at the turnout point. Furthermore, this device does not affect the normal adjustment of the switch rail during installation. Attached Figure Description

[0029] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0030] like Figures 1 to 3 As shown, this embodiment discloses an emergency rail breakage handling device, including a bridge plate 1. One side of the bridge plate 1 is provided with a rail web fitting part 1-1 and a rail top fitting part 1-2. The rail web fitting part 1-1 fits into the rail web of the base rail 3, and the rail top fitting part 1-2 fits into the side of the rail top of the base rail 3. A portal-shaped opening 1-3 is provided in the middle of the bridge plate 1 along its length, and the portal-shaped opening 1-3 is secured to the rail support 4 and the sleeper 5. The bottom of the bridge plate 1 is fixedly connected to the bottom of the base rail 3 by multiple hook-locking components 2, so that the bridge plate 1 as a whole supports the base rail 3, thereby improving the bending strength at the break. This allows for support and reinforcement without removing any rail components of the base rail 3, while preserving the stability of the original rail and ensuring traffic safety.
[0031] Among them, a wheel contact surface 1-4 is provided on the top surface of the bridge plate 1 near the main rail 3. The wheel contact surface 1-4 is set at an inclination and is in contact with the wheel 6, so that the bridge plate 1 can bear the load of the wheel 6 at the joint.
[0032] like Figures 4 to 5 As shown, in this embodiment, the gate opening 1-3 is convex in shape, and includes a rail support opening 1-3-1 and a sleeper opening 1-3-2. The rail support opening 1-3-1 is locked onto the outside of the rail support 4, and the sleeper opening 1-3-2 is locked onto the outside of the sleeper 5. There are a total of 6 hook-lock components 2, with three symmetrically distributed on each side of the sleeper 5.
[0033] In this embodiment, the length of the bridge deck 1 is the width of one sleeper 5 plus the distance between the two sleeper segments 5 on the left and right sides. That is, assuming the width of the sleeper 5 is 300 mm and the distance between the sleeper segments 5 is 300 mm, the length of the bridge deck 1 is 900 mm. This means the bridge deck 1 is located between the first and third sleepers 5 and spans over the second sleeper 5. This ensures that regardless of the location of the break, it will always be within the support and reinforcement range of the bridge deck 1, achieving the purpose of emergency handling.
[0034] like Figures 4 to 6 As shown, the hook-lock assembly 2 includes a hook-lock bolt 2-1 and a nut 2-2. The hook-lock bolt 2-1 is located below the base rail 3. One end of the hook-lock bolt 2-1 hooks into the bottom of the base rail 3 on the side away from the bridge plate 1, and the other end of the hook-lock bolt 2-1 passes through the bottom of the bridge plate 1 and is threadedly fastened to the nut 2-2. Specifically, a locking part 1-5 is provided at the bottom of the bridge plate 1, extending below the base rail 3. The locking part 1-5 has multiple locking holes 1-5-1. The hook-lock bolt 2-1 includes a threaded rod 2-1-1. One end of the threaded rod 2-1-1 is provided with a hook head 2-1-2. The hook head 2-1-2 is provided with a hook opening 2-1-3, which is engaged with the bottom of the base rail 3 on the side away from the bridge plate 1. The other end of the threaded rod 2-1-1 passes through the locking hole 1-5-1 and is threadedly fastened to the nut 2-2. After the nut 2-2 is tightened, the nut 2-2 is tightly attached to the side of the bridge plate 1 away from the base rail 3, so that the hook head 2-1-2 tightly hooks the bottom of the base rail 3, and at the same time fixes the bridge plate 1 and the base rail 3 together.
[0035] The top surface of the hook head 2-1-2 is lower than the top surface of the slide plate 7, thus ensuring the normal adjustment of the switch rail 8.
[0036] It should be noted that, based on the structure of the turnout switch section, there is a 20 mm gap between the bottom of the switch rail 8 and the bottom of the main rail 3, which provides sufficient space for the installation of the hook bolt 2-1 without affecting the normal adjustment of the switch rail 8.
[0037] In this embodiment, the torque of each hook-locking bolt 2-1 is designed to be 1100-1400 K˙M (which is consistent with the torque of the current rail adhesive freezing bolts and meets safety requirements).
[0038] In this embodiment, the bridge plate 1 is made of 40Cr heat-treated material to improve its bending strength.
[0039] In this embodiment, the bridge deck 1 is designed with an arc in the length direction that matches the basic rail 3, which serves to lower the slope.
[0040] It should be noted that the part of wheel 6 that is in contact with the wheel contact surface 1-4 is a conical surface with a very small taper, so the lateral force is also very small. After a rail break occurs, the train speed will be reduced and the train will pass under speed limit. When the train passes, wheel 6 presses on the main rail 3 and bridge plate 1 at the same time. With the close contact between bridge plate 1 and main rail 3, the pressure of wheel 6 is transmitted to the bottom of the rail and sleeper 5. Therefore, there is no risk that bridge plate 1 will detach due to the pressure of wheel 6, and the passage of the train is guaranteed.
[0041] The usage process of this utility model is as follows:
[0042] First, place the bridge plate 1 on the side of the base rail 3 where the joint is located, and place the rail support opening 1-3-1 and the sleeper opening 1-3-2 on the adjacent rail support 4 and sleeper 5. Fit the rail web fitting part 1-1 with the rail web of the base rail 3, and fit the rail top fitting part 1-2 with the side of the rail top of the base rail 3. Then, insert the hook opening 2-1-3 of the hook bolt head 2-1-2 into the bottom of the base rail 3 on the side away from the bridge plate 1. Pass the other end of the threaded rod 2-1-1 through the locking hole 1-5-1, and tighten the nut 2-2 to ensure that it is tightly attached to the bridge plate 1, so that the hook bolt head 2-1-2 tightly hooks the bottom of the base rail 3. At the same time, ensure that the rail web fitting part 1-1 is firmly attached to the rail web of the base rail 3, and the rail top fitting part 1-2 is firmly attached to the side of the rail top of the base rail 3. The construction is complete.
[0043] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
