[0001] AN OBSTACLE DETECTION EQUIPMENT FOR A RAILROAD VEHICLE

[0002] TECHNICAL FIELD

[0003] The invention relates to an obstacle detection equipment for a railroad vehicle comprising a transverse beam impact element in an impact unit.

[0004] BACKGROUND

[0005] In the literature, it may be encountered that there is an obstacle in front of the vehicle during the movement of railroad vehicles on the rail. For this reason, the railroad vehicle must apply sudden braking as an obstacle on the movement path, for example, in the event of a live exit. For this, solutions that enable the vehicle to brake suddenly by sending a signal to the train control monitoring system together with the impact on the railroad vehicle are required. In addition, it is to prevent a large object from coming to the wheel of the railroad systems vehicle, and in this case, to reduce the risk of accidents. In addition, systems that ensure minimal damage to living things in case of impact are not known in the current art.

[0006] Impact detection for a railroad vehicle is known in the technical field. For this purpose, the invention EP2548783 relates to impact detection for a vehicle. The invention discloses a detection equipment for detecting an impact between an impact partner and a vehicle, in particular a railroad vehicle. The detection equipment comprises a mounting bracket, at least one impact unit and at least one sensor device for connecting the detection equipment to the vehicle. The impact unit comprises at least one impact element for contact with the impact partner and is mechanically connected to the mounting bracket. The at least one sensor is designed to generate an impact signal as a result of the relative movement between the impact unit and the mounting bracket. In said system, there is no system that prevents the damage of the striking object after the impact.

[0007] All the problems mentioned above have made it necessary to make an innovation in the relevant technical field as a result. BRIEF DESCRIPTION OF THE INVENTION

[0008] The present invention relates to an obstacle detection equipment for a railroad vehicle for eliminating the above-mentioned disadvantages and bringing new advantages to the related technical field.

[0009] An object of the invention relates to an obstacle detection equipment for a railroad vehicle in which a signal is sent for sudden braking by providing obstacle detection using a mechanical sensor.

[0010] Another object of the invention is to provide an obstacle detection equipment for a railroad vehicle in which a form that can prevent damage to the living being entering under the railroad vehicle is provided.

[0011] Another object of the invention is to provide an obstacle detection equipment for a railroad vehicle in which it is desired to detect large objects that may enter under the railroad systems vehicle and the wheel of the vehicle in advance and to prevent the vehicle from emergency braking and derailing, thus preventing possible fatal and injured major accidents in case of derailment of the vehicle.

[0012] The present invention is an obstacle detection equipment for a railroad vehicle comprising at least one muffle support bracket provided in an impact unit to hold a transverse beam impact element; a mounting bracket in which the muffle support is mounted from a rear part of a muffle with a form to wrap around the bracket; a support arm assembled linearly from a mounting area at the rear part of the mounting bracket; and a mounting bracket support assembled from the rear area of the support arm and in the form of an angular slope in the horizontal axis (y) in order to realize all the objects that will emerge from the abovementioned and the following detailed description. Accordingly, its novelty comprises a spring that provides compression damping in the impact unit by moving in a reaction direction corresponding to a reaction force formed by the impact of the railroad vehicle on an obstacle or a living being during its movement in a movement direction; a mechanical stimulating element mounted on the muffle and moving in the reaction direction with the compression of the spring in the reaction direction; a mechanical sensor triggered by the movement of the mechanical stimulating element in the reaction direction by contacting a key and sending the impact state signal to a train control monitoring system. Thus, after the mechanical sensor is triggered, the signal to the train control monitoring system (TCMS) and the train control monitoring system operate the emergency brake of the vehicle by understanding that the railroad vehicle is in an emergency state and needs to brake.

[0013] A possible embodiment of the invention is characterized in that the reaction direction in which the spring is compressed is in a plane between a direction opposite to the movement direction corresponding to a reaction force and a vertical direction. Thus, considering that the movement direction of the railroad vehicle is +x direction, the mechanical stimulating element can hit the sensor key when the spring is compressed in the xz plane by moving in the -x direction and upwards in the z direction.

[0014] A possible embodiment of the invention is characterized in that the impact element is a composite material containing s-glass fiberglass material. Thus, a form is provided to prevent damage to the creature entering under the vehicle.

[0015] A possible embodiment of the invention is characterized in that it is mounted on a second arm with a first arm from the ends of the spring. Thus, a spring assembly that provides damping due to impact is formed in the rear part.

[0016] A possible embodiment of the invention is characterized in that the bonding resin in the composite material in the impact element is a polyester-based vinyl ester resin. Thus, the resin with high water resistance is selected.

[0017] A possible embodiment of the invention is characterized in that the single layer of s-glass fiberglass material in the impact element, muffle and muffle support bracket is nominally in the range of 0.12 to 0.25 mm thickness and 0.17 mm thickness in line with the requirements and accessibility of our model. Thus, a layered elastic structure is provided.

[0018] A possible embodiment of the invention is characterized in that the amount of s-glass fiberglass material in the composite material of the impact element is between 25% and 30%. Thus, the s-glass fiberglass is in the same category as the e-glass fiberglass, and the flexibility coefficient and tensile strength are higher in the range of 25%-30%.

[0019] A possible embodiment of the invention is characterized in that it comprises a filament wrap in the first layer of the composite material in the impact element and consists of seven layers of fiberglass material. Thus, since the impact element is in a round structure, its roundness is in the form of a filament wrap, and a durable structure is obtained since there are seven layers of fiberglass material in total. A possible embodiment of the invention is characterized in that the first arm is connected to the muffle. Thus, a spring that will provide damping to the backward impact element depending on the impact can be connected.

[0020] A possible embodiment of the present invention is characterized in that adjustment at different reaction forces with structural changes to be made is provided in the spring.

[0021] A possible embodiment of the invention is characterized in that it can be integrated into all railroad system vehicles after the changes to be made in the body.

[0022] A possible embodiment of the invention is characterized in that the second arm is connected to a connection plate provided at the rear of the support arm in such a way that the spring is in a horizontal and angular position. Thus, a connection can be made in such a way that the spring can be compressed in an angular position.

[0023] A possible embodiment of the invention is characterized in that the 7-layer of the composite material in the impact element is added at angles of 90°, +45°, -45°, 0°, -45°, +45° and 90°, respectively. Thus, the resistant structure in the fiberglass material can be provided.

[0024] A possible embodiment of the invention is characterized in that the composite material in the impact element is combined with vacuum in a way that uses the same layer order and angles in the overlapping joints. Thus, the two parts are combined by laying by hand using the same layer order and angles in the part to be joined by vacuum joining method.

[0029] DETAILED DESCRIPTION OF THE INVENTION A smart protection device and working method of the invention are explained with examples that do not have any limiting effect only for a better understanding of the subject in this detailed description.

[0030] Figure 1 shows an obstacle detection equipment for a railroad vehicle of the invention from a top perspective, Figure 2 shows a front perspective, and Figure 3 shows a side perspective. There is an impact unit (26) in an obstacle detection equipment for a railroad vehicle (10) given in the Figures. A transverse beam impact element (12) is located in the impact unit (26). In the invention, there is at least one muffle support bracket (14) provided to hold a transverse beam impact element (12) in the impact unit (26). Here, the muffle support is shaped with a muffle (15) to wrap over the bracket (14). A mounting bracket (18) is mounted at a rear portion of the muffle (15). From a mounting area at the rear of the mounting bracket

[0031] (18), a support arm (20) is mounted in a linear manner. Here, a mounting bracket support (22) is mounted from the rear area of the support arm (20). The mounting bracket support (22) is in the form of an angular inclination in the movement axis (x). In an obstacle detection equipment for a railroad vehicle (10) of the invention, there is a spring (32) that provides compression and damping in the impact unit (26) by moving in a reaction direction (B) in which the railroad vehicle corresponds to a reaction force formed by hitting an obstacle or a living being during its movement in a movement direction (A). Here, there is a mechanical stimulating element (34) mounted on the muffle (15) and moving in the reaction direction with the compression of the spring (32) in the reaction direction (B). In addition, there is a mechanical sensor (40) in an obstacle detection equipment for a railroad vehicle (10) of the invention, which is triggered by contacting a sensor key (42) with the reaction direction movement (B) of the mechanical stimulating element (34) and sends the impact condition signal to a train control monitoring system. In this way, after the mechanical sensor (40) is triggered, the signal to the train control monitoring system (TCMS) and the train control monitoring system operate the emergency brake of the vehicle by understanding that the vehicle is in an emergency and needs to brake. Here, the muffle support bracket (14) and the mechanical stimulating element (34) are assembled together using a plurality of bolts (16) from the holes drilled through the muffle. In addition, it is made by passing a mounting shaft

[0032] (19) through the holes opened in the lateral walls of the bracket and support arm in order to mount the mounting bracket (18) and the support arm (20) through the end parts. Again, the mounting bracket support (22) is mounted to the railroad vehicle from a rear connection area (24) at the rear so that the obstacle detection equipment (10) is connected to the railroad vehicle thanks to the mounting of the mounting bracket support (22). The reaction direction (B) in which the spring (32) of the invention is compressed is in a plane between a direction opposite to the movement direction (A) corresponding to a reaction force and a vertical direction. In this way, considering that the movement direction of the railroad vehicle is +x direction, the mechanical stimulating element (34) can hit the sensor key (42) with the compression of the spring (32) in the xz plane by moving in the -x direction and in the vertical axis (z) in the +z direction. The impact element (12) mentioned in the invention is a composite material containing s-glass fiberglass material. In this way, a form is provided to prevent damage to the creature entering under the vehicle. In addition, the spring (32) mentioned in the invention is mounted to a second arm (30) with a first arm (28) at its ends. In this way, a spring (32) assembly that provides damping due to impact is formed in the rear part. Here, the first arm (28) is connected to the muffle (15). In this way, a connection can be made to the spring (28) that will provide damping to the backward impact element (12) depending on the impact. In addition, the second arm (30) is connected to a connection plate (36) provided at the rear of the support arm (20) so as to ensure that the spring (32) is in a horizontal and angular position. Thus, a connection can be made so that the spring (32) is compressed in an angular position. Also, in the mechanical sensor (40), at least one bolt (44) is mounted, for example, with 2 screws from a lateral connection area (38) provided in the connection plate (36). Again, from the holes drilled in the connection plate (36), the support arm (20) and the mounting bracket support (22) are mounted using a plurality of bolts (46). In one embodiment, the bonding resin in the composite material in the impact element (12) is a polyester-based vinyl ester resin. In this way, the resin with high water resistance is selected. The s-glass fiberglass material in the impact element (12) of the invention is in the nominal range of 0.12 to 0.25 mm thickness of the single layer and is 0.17 mm thick in line with the requirements and accessibility of our model. A layered elastic structure is provided in this way. The amount of s-glass fiberglass material in the composite material of the impact element (12) in the invention is between 25% and 30%. In this way, s-glass fiberglass is in the same category as e-glass fiberglass, and its flexibility coefficient and tensile strength are higher in the range of 25%-30%. Here, the composite material in the impact element (12) comprises the filament wrap in its first layer and is in the form of 7 layers of fiberglass material. In this way, since the impact element (12) is in a round structure, its roundness is in the form of a filament wrap, and a durable structure is obtained since it is a total of 7 layers of fiberglass material. In addition, the 7-layer of the composite material in the impact element (12) is stacked at angles of 90°, +45°, -45°, 0°, -45°, +45° and 90°, respectively. The resistant structure in the fiberglass material can be provided in this way. In the invention, the composite material in the impact element (12) is combined with the muffle (15) and the muffle support (14) of the present invention as a composite, with the help of the mold, the stacking is combined with the vacuum in such a way that the similar layer order and angles in the impact element are used. In this way, the parts to be joined by the vacuum joining method are combined by hand tilting using the same layer order and angles in the part to be joined. In addition, the weight of the material, which is 9.5 kg in the first structure, is reduced to 3.05 kg by providing a thickness of 1 ,5mm thick composite material, and it is technically 53% more elastic material, and 8.5 times more durable material is obtained.
