Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0082] The obstacle remover provided in this embodiment can meet the requirements of speed grade obstacle remover in EN15227 standard. The obstacle remover provided in the embodiment of the present invention can solve the technical problems of low train running speed and poor safety performance caused by the obstacle being pushed by the obstacle remover in the track in the current related technology.

[0083] The obstacle remover provided in this embodiment can meet the requirements of speed grade obstacle remover in EN15227 standard. The obstacle remover provided in this embodiment of the application can solve the technical problems of low train running speed and poor safety performance in the current related technology because the obstacle remover may push obstacles in the track.

[0084] Some embodiments of the present application provide a deflector, see Figure 1 , Figure 2 and Figure 4, the obstacle remover includes an energy absorbing obstacle remover 1. The energy absorbing obstacle remover 1 includes a fixed shell 111, a sliding cover 112 and an energy absorbing unit 12, wherein the fixed shell 111 and the sliding cover 112 are arranged to form a closed accommodating space 110, and the sliding cover 112 is telescopically connected to the fixed shell 111 for removing obstacles. The energy absorbing unit 12 is located in the accommodating space 110, and the sliding cover 112 abuts against the energy absorbing unit 12 for buffering. The sliding cover 112 is set to be telescopically connected to the fixed shell 111. When a collision occurs, the sliding of the sliding cover 112 can absorb part of the energy, avoiding a hard collision that causes the sliding cover 112 to deform. And the energy absorbing unit 12 abuts against the sliding cover 112 to absorb the destructive energy transmitted by the sliding cover 112.

[0085] Specifically, an energy absorbing unit 12 is used inside the accommodation space 110 . When a collision occurs, the energy absorbing unit 12 abuts against the sliding cover 112 to generate deformation and absorb energy. When replacing, only the energy absorbing unit 12 in the accommodation space 110 needs to be replaced.

[0086] The obstacle remover provided in the present application has a sliding cover 112 and a fixed shell 111 that are telescopically connected. When a collision occurs, the sliding cover 112 slides to absorb a portion of the energy, thereby avoiding a hard collision that causes the sliding cover 112 to deform. During the sliding process, the sliding cover 112 makes the energy absorbing unit 12 abut against the sliding cover 112 to absorb the destructive energy transmitted by the sliding cover 112.

[0087] The energy absorbing unit 12 with different structures provides the following embodiments:

[0088] Embodiment 1:

[0089] See Figure 4 The energy absorbing unit 12 includes a first energy absorbing element (not shown). The first energy absorbing element is a honeycomb component, which is formed by splicing a plurality of columns, and the columns are provided with honeycomb-shaped through holes along the axial direction. The honeycomb energy absorbing unit has a simple structure.

[0090] Embodiment 2:

[0091] See also Figure 5 and Figure 6 The energy absorbing unit 12 includes a second energy absorbing element 1202, which includes a first mounting plate 123, an energy absorbing tube 121 and a cutting tool 122. The first mounting plate 123 is disposed in the accommodation space 110, the energy absorbing tube 121 is disposed in the accommodation space 110 for collision energy absorption, one end of the energy absorbing tube 121 is passed through the first mounting plate 123, the cutting tool 122 is disposed on the first mounting plate 123 and abuts against the tube wall of the energy absorbing tube 121 for cutting the tube wall of the energy absorbing tube 121 to form a cutting surface 1210 on the side wall of the energy absorbing tube 121.

[0092] Specifically, the cutting tool 122 can move relative to the energy absorbing tube 121. When a collision occurs, the first mounting plate 123 drives the cutting tool 122 to cut along the side wall of the energy absorbing tube 121, and absorbs energy by cutting the side wall of the energy absorbing tube 121, that is, by cutting the inner wall of the energy absorbing tube 121 to dissipate the energy generated by the collision of the vehicle. The first mounting plate 123 facilitates the installation of the energy absorbing tube 121 in the fixed shell 111, thereby forming a planing type energy absorbing unit.

[0093] In this embodiment, see further Figure 6 , the first mounting plate 123 is a stepped plate. The first mounting plate 123 includes a main body 1231 and a raised portion 1232. The main body 1231 is arranged away from the energy absorbing tube 121, and a guide hole 1230 is provided on the main body 1231. The raised portion 1232 extends from the end face of the main body 1231 toward the direction of the energy absorbing tube 121. The guide hole 1230 passes through the raised portion 1232, and the energy absorbing tube 121 extends into the guide hole 1230 from one side of the raised portion 1232. The cutting tool 122 is installed in the raised portion 1232, and the cutting tool 122 is a columnar structure. The length of the raised portion 1232 is less than the length of the main body 1231, so that the first mounting plate 123 is a stepped plate with thin sides and thick middle. The thickness in the middle is to ensure the installation space of the cutting tool 122, and the thickness on both sides is to consider weight reduction, so that the overall weight is lightweight.

[0094] Of course, in other embodiments, the length of the protrusion 1232 may also be greater than the length of the main body 1231, as long as it is thick in the middle and thin on both sides, and there is no limitation here.

[0095] Embodiment three:

[0096] See Figure 7 and Figure 8 The energy absorbing unit 12 includes a third energy absorbing element 1203, which includes a second mounting plate 126, an expansion tube 124 and a cone tube 125. The second mounting plate 126 is provided with a first mounting hole (not shown), one end of the expansion tube 124 is fixed to the second mounting plate 126, and the tube cavity of the expansion tube 124 is connected to the first mounting hole, one end of the cone tube 125 passes through the first mounting hole of the second mounting plate 126 and extends into the tube cavity of the expansion tube 124, the outer diameter of the cone tube 125 is greater than the inner diameter of the expansion tube 124, that is, the cone tube 125 and the expansion tube 124 are interference fit, so that when a collision occurs, the cone tube 125 squeezes the expansion tube 124 to deform so as to absorb the energy generated by the vehicle when the collision occurs, that is, the cone tube 125 expands the expansion tube 124, and the energy generated by the vehicle collision is dissipated through the plastic deformation of the expansion tube 124. The second mounting plate 126 is sleeved on the cone tube 125 , and the second mounting plate 126 is used to mount the cone tube 125 in the fixed shell 11 .

[0097] Specifically, one end of the cone tube 125 is closed, and the expansion tube 124 is compressed to abut against the closed end of the cone tube 125, which can limit the moving distance of the expansion tube 124 to a certain extent. The second mounting plate 126 is provided with connecting holes 1260 around it, and the fasteners of screws pass through the connecting holes 1260, so that the second mounting plate 126 is installed in the fixed shell 11 to form an expansion tube type energy absorption unit.

[0098] It should be noted that the above-mentioned energy absorbing elements can be used in combination. For example, the second energy absorbing element 1202 in the second embodiment can be used in combination with the first energy absorbing element. That is, the energy absorbing tube 121 of the second energy absorbing element 1202 can be installed in the first energy absorbing element. Specifically, a second mounting hole is provided on the first energy absorbing element, and the energy absorbing unit 12 also includes a second energy absorbing element 1202. The difference from the above-mentioned second embodiment is that the other end of the energy absorbing tube 121 extends into the second mounting hole and abuts against the hole wall of the second mounting hole. The first mounting plate 123 is located on the outside of the first energy absorbing element.

[0099] For example, the third energy absorbing element 1203 in the third embodiment can be used in combination with the first energy absorbing element. That is, the expansion tube 124 of the third energy absorbing element 1203 can be installed in the first energy absorbing element. Specifically, a second mounting hole is provided on the first energy absorbing element, and the energy absorbing unit 12 also includes the third energy absorbing element 1203. The difference from the above-mentioned third embodiment is that the other end of the expansion tube 124 extends into the second mounting hole and abuts against the hole wall of the second mounting hole. The second mounting plate 126 is located on the outside of the first energy absorbing element.

[0100] In one embodiment of the present application, see Figure 4 In order to ensure the relative sliding between the fixed shell 111 and the sliding cover 112, a sliding rail 1110 is provided on the side wall of the fixed shell 111, and a sliding groove 1120 slidably connected to the sliding rail 1110 is provided on the side wall of the sliding cover 112, or a sliding groove 1120 is provided on the side wall of the fixed shell 111, and a sliding rail 1110 slidably connected to the sliding groove 1120 is provided on the side wall of the sliding cover 112. The cooperation between the sliding rail 1110 and the sliding groove 1120 enables the fixed shell 111 and the sliding cover 112 to slide relative to each other.

[0101] Specifically, in this embodiment, the fixed shell 111 includes a shell 1111 and a first end plate 1112 arranged opposite to each other. The shell 1111 and the first end plate 1112 form a rectangular accommodation space with one side open, the first end plate 1112 bends and extends from the end of the shell 1111 toward the sliding cover 112, and a slide rail 1110 is provided on the inner wall of the first end plate 1112. The slide rail 1110 is a long strip-shaped protrusion extending along the extension direction of the first end plate 1112. The sliding cover 112 includes a cover body 1121 and two oppositely arranged sliders 1122. The cover body 1121 and the sliders 1122 surround a rectangular accommodating space with an opening on one side. The slider 1122 bends and extends from the end of the cover body 1121 toward the fixed shell 111. The slider 1122 is provided with a slide groove 1120. The slide groove 1120 is a long strip-shaped groove with openings at both ends. The long strip-shaped groove cooperates with the long strip-shaped protrusion to realize relative sliding between the fixed shell 111 and the sliding cover 112.

[0102] In one embodiment of the present application, the cover body 1121 includes a first plate body 1123, a second plate body 1124, a first side plate 1125, and a second side plate 1126. The first plate body 1123 is vertically arranged in the vertical direction, the second plate body 1124 is arranged to intersect with the first plate body 1123, and the angle a formed by the intersection of the first plate body 1123 and the second plate body 1124 is 120° to 160°. The first side plate 1125 extends from the side of the first plate body 1123 toward the fixed shell 111, and a part of the first side plate 1125 is plugged into the fixed shell 111. The second side plate 1126 is bent and extended from the side of the second plate body 1124 toward the fixed shell 111, and a part of the second side plate 1126 is plugged into the fixed shell 111.

[0103] The angle a formed by the intersection of the first plate 1123 and the second plate 1124 is 120° to 160°, that is, the first plate 1123 and the second plate 1124 are set in a V shape, so that the snow remover has the function of sweeping snow. When the angle is within this range, the snow sweeping effect is better. When the angle is too large, the snow will be concentrated behind the snow remover through the upper end of the first plate 1123, causing the snow to enter between the wheels and the track and cannot be discharged to the sides of the road. When the angle is too small, according to the definition in EN15227, after the distance from the highest point of the first plate 1123 to the track is determined, the total area of ​​the material will increase, which increases the cost. Of course, the angle a between the first plate 1123 and the second plate 1124 can not only sweep snow but also remove other obstacles, that is, the first plate 1123 and the second plate 1124 have the function of diversion, which is not limited here.

[0104] Part of the first side plate 1125 and part of the second side plate 1126 are both plugged into the fixed shell 111 , so that there is space for relative movement between the sliding cover 112 and the fixed shell 111 .

[0105] Specifically, in this embodiment, the housing 1111 includes a third plate 1113, a third side plate 1114, and a fourth side plate 1115. The third plate 1113 is disposed opposite to the first plate 1123 and the second plate 1124, the third side plate 1114 is bent and extended from the side edge of the third plate 1113 toward the first side plate 1125, a portion of the third side plate 1114 is plugged into the first side plate 1125, the fourth side plate 1115 is bent and extended from the side edge of the third plate 1113 toward the second side plate 1126, a portion of the fourth side plate 1115 is plugged into the second side plate 1126, so that there is space for relative movement between the fixed housing 111 and the sliding cover 112.

[0106] In one embodiment of the present application, the tip area 1127 of the first plate body 1123 and the second plate body 1124 has a curved surface structure, that is, the first plate body 1123 and the second plate body 1124 have a smooth transition and are in a circular arc plate structure. The curved surface structure of the first plate body 1123 and the second plate body 1124 is to adapt to multi-directional forces and try to ensure that the force and the contact surface are close to a vertical state, thereby increasing the strength of the sliding cover 112 to a certain extent.

[0107] In order to further increase the strength of the energy absorbing and obstacle removing device 1, the energy absorbing and obstacle removing device 1 further comprises a pressing plate 13, which is arranged on a side of the energy absorbing unit 12 facing the sliding cover 112. The pressing plate 13 can withstand a certain impact force to a certain extent.

[0108] In one embodiment of the present application, see Figure 2 The energy absorbing and obstacle removing device 1 further includes a reinforcement member 14, which is disposed on the outside of the fixed shell 111 and can strengthen the strength of the energy absorbing and obstacle removing device 1 to a certain extent. The reinforcement member 14 includes a connecting plate 141 and a bending plate 142 extending from the side of the connecting plate 141 toward the fixed shell 111, and the bending plate 142 is fixedly connected to the fixed shell 111. Specifically, there are two bending plates 142, which are respectively disposed on opposite sides of the connecting plate 141, and the two bending plates 142 and the connecting plate 141 are surrounded to form a hollow structure.

[0109] In one embodiment of the present application, see Figure 1 The obstacle clearing device also includes two obstacle clearing wings 2, which are respectively connected to the two ends of the fixed shell 111 and are axially symmetrical with respect to the fixed shell 111. The obstacle clearing wings 2 are inclined to the fixed shell 111, so that the obstacle clearing wings 2 have an obstacle clearing function.

[0110] The obstacle clearing wings 2 on both sides are welded by metal plates, and have the characteristics of stable structure, strong rigidity and large load-bearing capacity. They can effectively push obstacles to both sides to ensure that there are no obstacles on the track, while ensuring that the structure of the obstacle clearing wings 2 does not yield and deform.

[0111] In one embodiment of the present application, see Fig. 9 , the obstacle removal wing 2 includes a first wing 21 and a second wing 22. Among them, the first wing 21 is fixedly connected to the first plate body 1123, the second wing 22 is fixedly connected to the second plate body 1124, and the angle b formed by the intersection of the second wing 22 and the first wing 21 is 120°~160°. The angle between the first wing 21 and the second wing 22 is for the convenience of snow removal. When the angle is within this range, the snow removal effect is better. When the angle is too large, the snow will be concentrated behind the obstacle removal device through the upper end of the first wing 21, causing the snow to enter between the wheels and the track and cannot be discharged to both sides of the road. When the angle is too small, according to the definition in EN15227, after the distance from the highest point of the first wing 21 to the track is determined, the total material area will increase, which increases the cost. Of course, in other embodiments, the angle between the first wing 21 and the second wing 22 is not only convenient for snow removal, but also for removing other obstacles.

[0112] Specifically, the first wing plate 21 and the first plate body 1123 are fixed by welding, and the second wing plate 22 and the second plate body 1124 are fixed by welding.
