Description

Technical Field

[0001] The present disclosure relates to an embodiment that relates to the technical field of obstacle removers, and in particular to an obstacle remover equipped with an aluminum honeycomb-clad energy absorbing device. Background Art

[0002] As one of the passive safety protection devices of rail transit, the main function of the snowmobile is to remove obstacles on the track during the train's operation, while protecting the wheels and bottom of the rail train, ensuring that the car body is not damaged or slightly damaged, and avoiding accidents such as train derailment.

[0003] A cowcatcher is a device installed at the bottom of the head car of a rail train. The traditional cowcatcher is a purely rigid structure that meets the static strength requirements of the cowcatcher in the EN15227-2008 standard. However, it does not have energy absorption properties, which means that during the operation of the train, once it collides with an obstacle, the cowcatcher is overloaded and there is a risk of falling off, affecting normal use and causing significant losses. Summary of the invention

[0004] In response to the existing technical problems, the present invention provides an aluminum honeycomb-clad energy absorber with a built-in obstacle remover, which is used to optimize the energy absorption capacity of the obstacle remover. When the obstacle remover collides with an obstacle, the aluminum honeycomb energy absorption device is deformed to reduce the impact of the obstacle on the fixed part, thereby improving the collision resistance of the obstacle remover.

[0005] To achieve the above-mentioned purpose of the invention, the present invention provides a kind of obstacle remover, comprising: a sliding part, installed at the bottom front end of the carriage of a rail vehicle, the obstacle remover sliding part is used to directly contact the obstacle; a fixed part, installed at the bottom of the carriage of a rail vehicle, the obstacle remover fixed part and the obstacle remover sliding part are connected through a sliding part slider and a fixed part slider, as a rigid bracket, mainly playing the role of overall support and connection between the obstacle remover and the vehicle body; an aluminum honeycomb coated energy absorber, installed between the sliding part and the fixed part, the aluminum honeycomb coated energy absorber is fixedly connected to the fixed part, and in the process of the train colliding or clearing obstacles, the sliding part compresses the aluminum honeycomb coated energy absorber to allow the aluminum honeycomb coated energy absorber to deform under the action of the collision force and further absorb the collision energy.

[0006] Furthermore, the sliding part comprises: a sliding part main body bracket, which is installed at the front end of the sliding part; a sliding part crossbeam, the rear end of which contacts the aluminum honeycomb-wrapped energy absorber and is connected to the inner side of the sliding part main body bracket, and the sliding part crossbeam breaks when subjected to a collision force greater than the bearing capacity of the sliding part to initially absorb the collision energy. When a train collides, the sliding part crossbeam compresses the energy absorber in the direction of the train's travel to absorb the collision energy.

[0007] Furthermore, the sliding part main body bracket includes: a sliding part center plate, a profile bending part, a sliding part slider and a sliding part positioning part; the front end of the profile bending part A112 is fixedly connected to both sides of the sliding part center plate at a certain angle and is distributed in a mirror image; there are four sliding part positioning parts, and the four sliding part positioning holes are on both sides of the travel direction and are relatively arranged on the sliding part profile bending part.

[0008] Furthermore, the sliding part positioning member includes a sliding part positioning member supporting profile and a sliding part positioning member mounting profile, which are spaced apart in a transverse direction perpendicular to the direction of travel. The sliding part positioning member supporting profile is positioned by relying on the sliding part positioning member mounting profile. When the obstacle clearing plate of the obstacle clearing device is worn, the sliding part positioning member supporting profile slides to change the relative position of the sliding part positioning member mounting profile and the sliding part positioning member supporting profile.

[0009] Furthermore, the fixing part includes: an outer fixing part component installed on the outer side of the fixing part; a fixing part crossbeam, the front end of the fixing part rear inner panel of the fixing part crossbeam contacts the rear flange of the energy absorber of the aluminum honeycomb coated energy absorber, and is connected to the inner side of the outer fixing part component.

[0010] Furthermore, the external component of the fixing part includes: a fixing part profile bending part B is connected to a profile bending part C, and the inner profile bending part C is connected to a fixing part slider to form a whole, and a fixing part positioning part A and a fixing part positioning part B are respectively provided on the fixing part profile bending part B and the profile bending part C.

[0011] Furthermore, the fixed part positioning member A includes: a fixed part positioning member supporting profile A and a fixed part positioning member supporting profile A; the fixed part positioning member B includes: a fixed part positioning member supporting profile B and a fixed part positioning member supporting profile B; a total of two fixed part positioning members A are arranged on the fixed part profile bending member C, and a total of four fixed part positioning members B are arranged on the fixed part profile bending member B, all along the traveling direction and mirror-arranged, the fixed part positioning member installing profile A and the fixed part positioning member supporting profile B.

[0012] Furthermore, the rear inner panel of the fixed part is in contact with the rear flange of the energy absorber of the aluminum honeycomb wrapped energy absorber and is installed on the crossbeam frame of the fixed part; the crossbeam reinforcement plate of the fixed part is connected to the crossbeam of the fixed part on the inner side of the outer component of the fixed part.

[0013] Furthermore, the sliding portion slider and the fixing portion slider are meshed with each other.

[0014] Furthermore, the aluminum honeycomb wrapped energy absorber includes: flange, skin, guide tube, honeycomb core and partition; the cover plate is installed at the front end of the guide tube, the guide tube is used as the central structure of the aluminum honeycomb wrapped energy absorber, the flange, honeycomb core and partition are installed on the guide tube in series, and the skin wraps the whole structure; the flange of the aluminum honeycomb wrapped energy absorber includes: upper flange and lower flange, the honeycomb core of the aluminum honeycomb wrapped energy absorber includes: honeycomb core A and honeycomb core B; the guide tube and the center hole on the upper flange form a sliding fit, bear non-axial load, ensure that the honeycomb core moves longitudinally in one dimension during the compression process, and play a positioning and limiting role together with the skin; the honeycomb core A and the honeycomb core B are separated by a partition, and the two honeycomb cores are respectively arranged in series as the first-stage energy absorbing element and the second-stage energy absorbing element along the direction of train travel, and are wrapped by the skin. The first energy absorbing component and the second energy absorbing component are both aluminum honeycomb structures, which are connected in series along the direction of train travel, separated by a partition, and wrapped by the skin. When a train collides, the first energy-absorbing component close to the sliding part begins to compress, acting as a primary energy-absorbing buffer. At this time, the second energy-absorbing component is also stressed but deformed less, acting as a secondary energy-absorbing buffer. In addition, the skin also plays an energy-absorbing role to a certain extent. When the snowcatcher is compressed, the skin is also stressed and deformed, playing a certain degree of buffering role.

[0015] The advantages of the present invention over the prior art are as follows: when a train collides or the obstacle clearing plate is used to clear an obstacle, the sliding part of the obstacle clearer compresses the aluminum honeycomb-coated energy absorber under the action of the impact force, while the fixed part of the obstacle clearer remains fixed, and the sliding part ensures the transmission of force in the direction of the train's travel through the slider of the fixed part. The aluminum honeycomb-coated energy absorber serves as the core structure that bears the energy absorption function. When the obstacle clearer is overloaded, the aluminum honeycomb-coated energy absorber dissipates the energy generated by the vehicle collision in the form of its own plastic deformation, reduces the impact of obstacles on the fixed part, and thus reduces the risk of the fixed part falling off. Therefore, the aluminum honeycomb-coated energy absorber improves the overall energy absorption performance of the obstacle clearer while improving the collision resistance of the obstacle clearer and reducing losses.

[0016] The present invention arranges an oil collecting box above the heating module at the bottom of the insulation box to collect food soup and ensure that the food soup does not flow to the surface or inside of the heating module, thereby avoiding smoke and soup dripping on the surface of the heating module to block the vents. The unique design of the air outlet cavity and the return air cavity of the oil collecting box ensures smooth circulation of hot air in the insulation box and normal insulation function. It is the most ideal design in the field of rail vehicle insulation boxes, which not only realizes the insulation function, but also is light in weight, firmly fixed, and has no noise. The oil collecting pan can be taken out by pressing the fixed spring piece, which is convenient for operation and can thoroughly clean the dirt on the oil collecting pan.

[0037] A snowplow is a device installed at the bottom of the head car of a rail vehicle. Its main function is to clear obstacles on the track to prevent them from entering the bottom of the vehicle and damaging the bogie, or causing the wheels to run over foreign objects and derail. At present, the front part of the snowplow is a snowplow plate, which is installed at the bottom of the car through an energy-absorbing device. When the snowplow plate collides with an obstacle, the energy-absorbing device deforms to absorb the energy during the collision. However, the energy-absorbing device is easily deformed and damaged under the action of the collision force, and needs to be replaced as a whole, resulting in large losses, and the energy-absorbing effect of the energy-absorbing device is not good.

[0038] Figure 1 It is a three-dimensional schematic diagram of a snow clearer according to an embodiment of the present disclosure.

[0039] The embodiment of the present disclosure provides a kind of obstacle remover, such as Figure 1 As shown, it includes a snowcatcher sliding part 1, a snowcatcher fixing part 2 and an aluminum honeycomb coated energy absorber 3. The snowcatcher sliding part 1 is installed at the bottom of the carriage of the rail vehicle, and is installed at the front end as a rigid bracket, and directly contacts the obstacle during the collision between the snowcatcher and the obstacle; the snowcatcher fixing part 2 is installed at the bottom of the carriage of the rail vehicle, and is also a rigid bracket, which mainly plays the role of overall support and connection between the snowcatcher and the vehicle body; the aluminum honeycomb coated energy absorber 3, as an energy absorbing mechanism, is installed between the snowcatcher fixing part and the sliding part. When the snowcatcher is overloaded, it dissipates the energy generated in the collision process by its own plastic deformation, thereby improving the collision resistance of the snowcatcher and reducing the loss of the snowcatcher.

[0040] According to the embodiments of the present disclosure, Figure 1 As shown, the obstacle clearer sliding part 1 and the obstacle clearer fixed part 2 are bent into an arc from front to back. At the same time, positioning holes are installed on both sides of the obstacle clearer sliding part 1 and the obstacle clearer fixed part 2 for positioning and installing the sliding part positioning member support profile 1142, the fixed part positioning member A support profile 2141, and the fixed part positioning member B support profile 2151. The overall structure is symmetrically arranged along the axis of the travel direction of the rail vehicle, which is beneficial for the airflow to flow backward along the side wall of the obstacle clearing plate and reduce the wind resistance during the travel of the rail vehicle.

[0041] Figure 2 Schematic diagram of the sliding part of the obstacle avoider according to the embodiment of the present disclosure. Figure 3 It is a schematic diagram of the main support of the sliding part of the obstacle remover according to an embodiment of the present disclosure.

[0042] According to the embodiments of the present disclosure, Figure 1 , Figure 2 and Figure 3As shown, the obstacle clearer sliding part 1 is mainly composed of a sliding part main body bracket 11 and a sliding part cross beam 12. The sliding part main body bracket 11 is installed at the front end of the sliding part, including a sliding part center plate 111, a profile bending part 112, a sliding part slider 113 and a sliding part positioning part 114. The front end of the profile bending part A112 is fixedly connected to both sides of the sliding part center plate 111 at a certain angle, and is distributed in a mirror image. The obstacle clearer sliding part positioning holes 114 are distributed on the profile bending part A112. The sliding part positioning holes 114 are composed of a sliding part positioning part installation profile 1142 and a sliding part positioning part support profile 1141, which are used to install the obstacle clearing plate. The sliding part cross beam 12 The rear end of the sliding part cross beam 12 contacts the aluminum honeycomb coated energy absorber 3 and is connected to the inner side of the sliding part main body bracket 11. The sliding part cross beam 12 breaks when subjected to a collision force greater than the bearing capacity of the sliding part 1, so as to initially absorb the collision energy. The sliding portion cross beam 12 is composed of a sliding portion base plate 121 , a sliding portion inner plate 122 and a sliding portion front reinforcement plate 123 .

[0043] In an exemplary embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the obstacle clearer sliding part main body bracket 11 and the sliding part cross beam 12 are connected through the sliding part center plate 111, the sliding part embedded plate 122 and the sliding part front reinforcement plate 123, the two ends of the sliding part base plate 121 are connected to the inner side of the profile bending part 112, the sliding part embedded plate 122 is embedded in the front side of the sliding part base plate 121, the rear end of the sliding part center plate 111 is fixedly connected to the sliding part embedded plate 122, and the sliding part front reinforcement plate 123 is embedded in the sliding part profile bending part A111, which supports the overall structure and improves the overall strength of the mechanism.

[0044] In an exemplary embodiment, Figure 1 and Figure 2 As shown, there are four positioning holes 114 for the sliding part of the obstacle remover. The four positioning holes 114 for the sliding part are arranged on both sides of the traveling direction and are arranged on the bending part of the sliding part profile to ensure the balance of the obstacle remover. The four positioning holes 114 for the sliding part each include a supporting profile 1141 for the sliding part positioning member and a mounting profile 1142 for the sliding part positioning member. The plurality of supporting profiles 1141 for the sliding part positioning member are spaced apart in the transverse direction perpendicular to the traveling direction to increase the rigidity strength of the sliding part positioning holes 114 of the mounting assembly. The supporting profile 1141 for the sliding part positioning member is positioned by the mounting profile 1142 for the sliding part positioning member. When the obstacle removal plate of the obstacle remover is worn, the supporting profile 1141 for the sliding part positioning member slides through the mounting profile 1142 for the sliding part positioning member. By changing the relative position of the mounting profile 1142 for the sliding part positioning member and the supporting profile 1141 for the sliding part positioning member, the position of the obstacle removal plate can be changed.

[0045] The obstacle avoider sliding part substrate 121 serves as the bottom structure of the sliding part and is in direct contact with the aluminum honeycomb coated energy absorber 3. When a train collides, the sliding part substrate 121 compresses the energy absorber in the direction of train travel to absorb the collision energy.

Figure 5 It is a schematic diagram of the external components of the fixed part of the obstacle remover according to the embodiment of the present disclosure. Figure 6 It is a schematic diagram of the cross beam of the fixed part of the obstacle remover according to the embodiment of the present disclosure.

[0047] According to the embodiments of the present disclosure, Figure 4 As shown, the obstacle clearer fixed part 2 is mainly composed of a fixed part outer component 21 and a fixed part cross beam 22. Among them, the fixed part outer component 21 mainly includes a profile bending part B211, a pier profile bending part C212 and a fixed part slider 213. The fixed part profile bending part B211 is connected to the profile bending part C212, and the inner profile bending part C212 is connected to the fixed part slider 213 to form a whole. The fixed part profile bending part B211 and the profile bending part C212 are respectively provided with a fixed part positioning part A214 and a fixed part positioning part B215; the fixed part cross beam 22 is composed of a fixed part cross beam frame 221, a fixed part cross beam reinforcement plate 222 and a fixed part rear inner plate 223.

[0049] In an exemplary embodiment, Figure 1 and Figure 2As shown, the obstacle remover includes two types of fixed part positioning parts, namely fixed part positioning parts A214 and fixed part positioning parts B215. There are two fixed part positioning parts A214 and four fixed part positioning parts B215, the fixed part positioning parts A214 are arranged on both sides of the travel direction and are relatively arranged on the fixed part profile bending part C212, and the fixed part positioning parts B215 are arranged on both sides of the travel direction and are relatively arranged on the fixed part profile bending part B211, so as to ensure the balance of the obstacle remover. Six sliding part positioning members (two fixed part positioning members A214 and four fixed part positioning members B215) The fixed part positioning member A214 includes a fixed part positioning member support profile A2141 and a fixed part positioning member installation profile A2142, and the fixed part positioning member B215 includes a fixed part positioning member support profile B2151 and a fixed part positioning member installation profile B2152. A plurality of fixed part positioning member support profiles 2141 and 2151 are spaced apart in a transverse direction perpendicular to the traveling direction to increase the rigidity strength of the fixed part positioning member. The fixed part positioning member support profiles 2141 and 2151 are positioned by the fixed part positioning member installation profiles 2142 and 2152. When the obstacle clearing plate of the obstacle clearing device is worn, the fixed part positioning member support profiles 2141 and 2151 are slid by the fixed part positioning member installation profiles 2142 and 2152, and the position of the fixed part positioning member support profiles 2141 and 2151 is changed, so that the position of the obstacle clearing plate can be changed.

[0050] The rear inner panel 223 of the fixed part of the obstacle avoider is used as the bottom structure of the fixed part, directly in contact with the aluminum honeycomb wrapped energy absorber 3. The front end of the fixed part cross beam 22 is in contact with the energy absorber rear flange 322 of the aluminum honeycomb wrapped energy absorber 3, and is installed on the fixed part cross beam frame 2211, and the upper side is connected to the inner side of the fixed part outer component 21. When the train collides, the sliding part base plate 121 compresses the energy absorber in the direction of the train's travel, and the fixed part rear inner panel 223 remains fixed to absorb the collision energy.

[0051] According to the embodiments of the present disclosure, Figure 1 , Figure 2 and Figure 4 As shown, the snowmobile sliding part 1 and the snowmobile fixed part 2 are respectively provided with a sliding part slider 113 and a fixed part slider 213, and the sliding part slider 113 and the fixed part slider 213 are meshed with each other. When the train collides, the aluminum honeycomb coated energy absorber 3 is compressed by force, and the snowmobile sliding part 1 slides along the traveling direction of the train, ensuring the one-dimensional sliding of the snowmobile sliding part 1 in the traveling direction of the train.

[0052] Figure 7 Schematic diagram of the aluminum honeycomb-clad energy absorber of the obstacle avoider according to an embodiment of the present disclosure. Figure 8 is a cross-sectional view of the aluminum honeycomb-clad energy absorber of the obstacle avoider according to an embodiment of the present disclosure.

[0053] According to the embodiments of the present disclosure, Figure 7 and Figure 8 As shown, the aluminum honeycomb wrapped energy absorber 3 mainly includes a flange 32, a skin 33, a guide tube 34, a honeycomb core 35 and a partition 36. The center hole cover plate 31 of the energy absorber is installed at the front end of the guide tube 34. The guide tube 34 serves as the central structure of the aluminum honeycomb wrapped energy absorber 3. The flange 32, the honeycomb core 35 and the partition 36 are installed on the guide tube 34 in series. The skin 33 wraps the whole structure to prevent the honeycomb structure from being exposed to the air. The guide tube 34 passes through the center hole of the upper flange 321 to form a sliding fit. The honeycomb core A351 and the honeycomb core B352 are separated by the partition 36 and sleeved on the guide tube 34. The bottom is sealed by the flange 322 below the bottom and fixedly connected to the fixed part.

[0054] According to the embodiments of the present disclosure, Figure 1 , Figure 7 and Figure 8 As shown, in this solution, two aluminum honeycomb wrapped energy absorbers 3 are connected in total and symmetrically arranged between the sliding part 1 and the fixed part 2 of the snowmobile along the traveling direction of the train, which improves the energy absorption capacity of the snowmobile while ensuring the balance of the snowmobile.

[0055] According to the embodiments of the present disclosure, Figure 7 and Figure 8 As shown, the flange (32) of the aluminum honeycomb wrapped energy absorber (3) includes: an upper flange 321 and a lower flange 322. The aluminum honeycomb wrapped energy absorber 3 includes a honeycomb core A351 and a honeycomb core B352. The two honeycomb cores are respectively arranged in series along the direction of train travel through a partition 36 as a first-stage energy absorbing element and a second-stage energy absorbing element, and are wrapped by a skin. When the train collides, the honeycomb core A351 of the first-stage energy absorbing component close to the sliding part begins to compress, serving as a first-stage energy absorbing buffer. At this time, the honeycomb core B352 of the second energy absorbing component is subjected to force at the same time but has a small deformation, serving as a second-stage energy absorbing buffer.

[0056] According to the embodiments of the present disclosure, Figure 7 and Figure 8 As shown, the skin 33 is used to isolate the aluminum honeycomb structure from the outside air and to limit the plastic deformation of the aluminum honeycomb structure to a certain extent. In addition, the skin 33 also plays an energy absorption role to a certain extent. When the snow remover is compressed, the skin 33 is also deformed by force, playing a certain degree of buffering role.

[0057] According to the embodiments of the present disclosure, Figure 8 As shown, the guide tube 34 and the center hole on the upper flange 321 form a sliding fit, bear non-axial loads, ensure that the honeycomb core 35 moves longitudinally in one dimension during the compression process, and play a positioning and limiting role together with the skin 33.

[0058] According to the snowcatcher provided by the present disclosure, when a train collides or the snowcatcher plate clears an obstacle, the snowcatcher sliding part 1 compresses the aluminum honeycomb-coated energy absorber 3 under the action of the impact force, while the snowcatcher fixed part 2 remains fixed, and the sliding part 1 ensures the transmission of force in the direction of the train's travel through the slider of the fixed part 2. The aluminum honeycomb-coated energy absorber 3 serves as the core structure that bears the energy absorption function. When the snowcatcher is overloaded, the aluminum honeycomb-coated energy absorber 3 dissipates the energy generated by the vehicle collision in the form of its own plastic deformation, reduces the impact of obstacles on the fixed part, and thus reduces the risk of the fixed part 2 falling off. Therefore, the aluminum honeycomb-coated energy absorber 3 improves the overall energy absorption performance of the snowcatcher while improving the collision resistance of the snowcatcher and reducing losses.

[0059] Compared with the prior art, the present invention is optimized in structure, and uses a sliding part positioning member installation profile 1141 and a sliding part positioning member support profile 1142. When the obstacle clearing plate of the obstacle clearer is worn, the obstacle clearing plate can be easily replaced.

[0060] Based on the above specific embodiments, the purpose, technical solutions and beneficial effects of the present invention are further described in detail. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
