Description

Technical Field

[0001] This utility model relates to the field of rail transit safety technology, specifically a train derailment rotation anti-collision device. Background Technology

[0002] Train derailment refers to the phenomenon where the wheelsets of a train leave the rails while the train is running. Derailments can be classified into four types: climbing derailment, sliding derailment, jumping derailment, and falling off the rails. Derailment accidents can be caused by a variety of factors, including uneven vehicle load, serpentine running, uneven track, and excessive wheel load reduction. To prevent more serious casualties and property damage after a train derailment, rotating anti-collision structures are generally installed on both sides of the track.

[0003] In terms of structural design, the kinetic energy of the train is usually reduced by structures such as anti-collision barrels and springs. However, after the spring is compressed and contracted, its elastic force can easily cause the train to shift back and continue to slide, thereby reducing the protective effect of the device. Utility Model Content

[0004] The purpose of this invention is to provide a train derailment rotation anti-collision device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a train derailment rotational anti-collision device, comprising an anti-collision barrel body, a column fixedly connected to the inner wall of the anti-collision barrel body, a cylinder fixedly connected to the side of the column near the anti-collision barrel body, an oil storage cylinder inside the cylinder, a working cylinder inside the cylinder, a base at the bottom of the cylinder, a piston slidably connected inside the working cylinder, a rod fixedly connected to the side of the piston away from the base, and a connecting spring movably sleeved on the surface of the rod.

[0008] As a further preferred embodiment of this technical solution, a support frame is provided at the bottom of the anti-collision barrel body, and cylinders are fixedly connected to the left and right sides of the support frame. A rack plate is fixedly connected to the output rod of the cylinder. A rotating gear is engaged on the side of the rack plate near the anti-collision barrel body, and a slider is fixedly connected to the side of the rack plate away from the cylinder.

[0012] This utility model provides a train derailment rotational anti-collision device, which has the following beneficial effects:

[0013] (1) When a train derails, the train's kinetic energy collides with the anti-collision barrel body and squeezes the anti-collision barrel body to deform it. The connecting spring is squeezed and contracted, thereby absorbing the train's kinetic energy. At the same time, the rod drives the piston to slide in the working cylinder. Under pressure, hydraulic oil enters the oil storage cylinder. During the movement of hydraulic oil, the piston and the valve on the base throttle the hydraulic oil, thereby achieving damping and improving the anti-collision effect.

[0014] (2) This utility model starts the cylinder, whose output rod drives the rack plate to move, and the slider slides in the guide groove. Due to the meshing of the rotating gear and the rack plate, the rotating gear drives the connecting shaft and the anti-collision barrel body to rotate. When the derailed train comes into contact with the anti-collision barrel body, the rotation of the anti-collision barrel body guides the direction of the train's movement, preventing it from continuing to move along the derailment direction, thereby achieving the purpose of blocking the train.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown, in this embodiment, a train derailment rotational anti-collision device includes an anti-collision barrel body 1, a column 2 fixedly connected to the inner wall of the anti-collision barrel body 1, a cylinder 3 fixedly connected to the side of the column 2 near the anti-collision barrel body 1, an oil storage cylinder 4 disposed inside the cylinder 3, a working cylinder 5 disposed inside the cylinder 3, a base 6 disposed at the bottom of the cylinder 3, a piston 7 slidably connected inside the working cylinder 5, a rod 8 fixedly connected to the side of the piston 7 away from the base 6, and a connecting spring 9 movably sleeved on the surface of the rod 8.

[0022] When a train derails, its kinetic energy collides with and deforms the anti-collision barrel 1, causing the connecting spring 9 to compress and absorb the train's kinetic energy. Simultaneously, the rod 8 drives the piston 7 to slide within the working cylinder 5. Under pressure, hydraulic oil enters the reservoir cylinder 4. During the rebound of the connecting spring 9, the oil pressure at the bottom of the cylinder 3 decreases, causing the hydraulic oil in the reservoir cylinder 4 to be pumped back into the working cylinder 5. Furthermore, during the movement of the hydraulic oil, the valves on the piston 7 and the base 6 throttle the hydraulic oil, thereby achieving damping and improving the anti-collision effect.

[0023] There are multiple anti-collision barrel bodies 1, and the multiple anti-collision barrel bodies 1 are made of plastic. There are multiple cylinder bodies 3, and the working cylinder 5 is filled with hydraulic oil. The connecting spring 9 is located between the cylinder body 3 and the anti-collision barrel body 1.

[0024] A rotating rod 10 is fixedly connected to the top of the anti-collision barrel body 1, a rubber sleeve 11 is fixedly connected to the surface of the anti-collision barrel body 1, and a connecting shaft 12 is fixedly connected to the bottom of the anti-collision barrel body 1.

[0025] A support frame 13 is provided at the bottom of the anti-collision barrel body 1. Cylinders 14 are fixedly connected to the left and right sides of the support frame 13. A rack plate 15 is fixedly connected to the output rod of the cylinder 14. A rotating gear 16 is engaged on the side of the rack plate 15 close to the anti-collision barrel body 1. A slider 17 is fixedly connected to the side of the rack plate 15 away from the cylinder 14. A guide groove 18 is provided inside the support frame 13.

[0026] By activating cylinder 14, its output rod drives rack plate 15 to move, and slider 17 slides in guide groove 18. Due to the meshing of rotating gear 16 and rack plate 15, rotating gear 16 drives connecting shaft 12 and anti-collision barrel body 1 to rotate. When the derailed train comes into contact with anti-collision barrel body 1, the rotation of anti-collision barrel body 1 guides the direction of train movement, preventing it from continuing to move along the derailment direction, thereby achieving the purpose of blocking the train. Cylinders 14 are provided on both sides of support frame 13. While one side cylinder 14 drives anti-collision barrel body 1 to guide, the other side cylinder 14 can drive the anti-collision barrel body 1 on that side to reverse. Thus, the rotation of anti-collision barrel body 1 can offset the kinetic energy of the train, thereby reducing the continued sliding distance of the train after derailment.

[0027] The rack plate 15 is located inside the support frame 13. The rotating gear 16 and the connecting shaft 12 are fixedly connected. There are two guide grooves 18, and the two guide grooves 18 are adapted to the slider 17.

[0028] A top plate 19 is fixedly connected to the top of the support frame 13, a battery 20 is fixedly connected to the top of the top plate 19, a support column 21 is fixedly connected to the top of the top plate 19, an mounting plate 22 is fixedly connected to the top of the support column 21, and a photovoltaic panel 23 is fixedly connected to the top of the mounting plate 22.

[0029] By adding photovoltaic panels 23 to the support frame 13, the absorbed solar energy is converted into electrical energy and stored in the battery 20, which can provide power to the cylinder 14 when it is working, thus improving the overall energy efficiency of the device.

[0030] The top plate 19 and the rotating rod 10 are rotatably connected, the battery 20 and the cylinder 14 are electrically connected, and the mounting plate 22 is inclinedly set on the top of the support column 21.

[0031] This utility model provides a train derailment rotational anti-collision device, the specific working principle of which is as follows:

[0032] In use, the cylinder 14 is activated, and its output rod drives the rack plate 15 to move. The slider 17 slides in the guide groove 18. Due to the meshing of the rotating gear 16 and the rack plate 15, the rotating gear 16 drives the connecting shaft 12 and the anti-collision barrel body 1 to rotate. When the derailed train comes into contact with the anti-collision barrel body 1, the rotation of the anti-collision barrel body 1 guides the direction of the train's movement, preventing it from continuing to move along the derailment direction. At the same time, the train collides with the anti-collision barrel body 1 due to its kinetic energy and squeezes the anti-collision barrel body 1, causing it to deform. The connecting spring 9 is squeezed and contracted, thereby absorbing the kinetic energy of the train. Meanwhile, the rod 8 drives the piston 7 to slide in the working cylinder 5. Under pressure, hydraulic oil enters the oil storage cylinder 4. During the movement of the hydraulic oil, the piston 7 and the valve on the base 6 throttle the hydraulic oil, thereby achieving damping and achieving the purpose of stopping the train.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
