An embodiment of the utility model provides a carbon slide subassembly of pantograph, wherein, the pantograph can go up and down through the detection of determine module convection cell. Fig. 1 is a schematic view of a carbon slide assembly according to an embodiment of the present invention, fig. 2 is a schematic view of a part of a carbon slide assembly according to an embodiment of the present invention, and fig. 3 is a cross-sectional view of a carbon slide assembly according to an embodiment of the present invention. Wherein fig. 3 is a sectional view taken along a section line AA' shown in fig. 1.

As shown in fig. 1 to 3, the carbon skid assembly 10 includes: the carbon strip device comprises a bracket 11, carbon strips 12, a first guide pipe 13, a second guide pipe 14 and a first connector 15. The bracket 11 includes a middle portion 111 and at least one arcuate portion 112 located in a longitudinal direction of the middle portion 111. The carbon strips 12 cover the first surface 111a of the middle portion 111. The first draft tube 13 is located between the first surface 111a of the middle portion 111 and the carbon strips 12. At least a portion of the second draft tube 14 is received within the arcuate corner 112. The first connector 15 connects the first duct 13 and the second duct 14 to a detection assembly (not shown).

According to the above embodiment, since the first duct 13 and the second duct 14 are disposed in the middle part 111 and the corner part 112 of the carbon slider assembly 10 of the pantograph, not only the state of the middle part 111 but also the state of the corner part 112 can be detected, and thus, the pantograph can be lowered in time even when the corner part 112 is damaged by an external force, and the pantograph and the power grid in contact with the pantograph can be prevented from being further damaged. Further, by disposing the second duct 14 inside the bow corner 112, it is not necessary to additionally provide a member for accommodating the second duct 14, for example, it is not necessary to cover the surface of the bow corner 112 with carbon strips, and thus, the amount of carbon material used can be reduced, and the weight of the entire carbon slide board assembly 10 can be reduced.

In some embodiments, the carbon skid assembly 10 may be employed in a variety of electrically driven vehicles. The electrically driven vehicle may include, for example, a motor train unit train, an electric locomotive, a magnetic levitation train, a light rail train, a subway train, or the like. In use, the carbon slide assembly 10 moves with a vehicle, and the carbon strip 12 may be brought into contact with a wire of an electrical grid to draw current from the grid through sliding friction to power the vehicle.

In some embodiments, the pantograph may be automatically raised and lowered by detection of fluid by the detection assembly. For example, the detecting component may detect the fluid pressure or flow of the first flow guide pipe 13 and the second flow guide pipe 14, so as to determine whether the first flow guide pipe 13 and the second flow guide pipe 14 are damaged, and further, when the first flow guide pipe 13 and the second flow guide pipe 14 are damaged, the detecting component can timely control the fast pantograph lowering valve of the pantograph to automatically and fast lower the pantograph to protect the pantograph and the power grid from further damage.

In some embodiments, the fluid in the first and second flow conduits 13, 14 may be a gas, a liquid, or other object that may flow.

In some embodiments, in the carbon slide plate assembly 10, the middle portion 111 of the bracket 11 may be a portion covered with the carbon strip 12, and an arcuate portion 112 may be provided on one or both sides in the length direction of the middle portion 111. In which the bow 112 (also referred to as a sheepfold or other name) is curved with a predetermined curvature.

In some embodiments, the middle portion 111 and the bow corner portion 112 of the bracket 11 may be integrally formed, thereby enabling to improve the strength of the bracket 11. The present invention is not limited to this, and the intermediate portion 111 and the bow corner portion 112 may be connected by a mounting member, thereby facilitating assembly of the second duct 14 and the bracket 11.

In some embodiments, as shown in fig. 3, a first draft tube 13 may be disposed between the intermediate portion 111 and the carbon strip 12. For example, a groove 121 may be formed at an intermediate position of the lower end surface 12b of the carbon rod 12, and the first duct 13 may be accommodated in the groove 121 and be retained by the groove 121 and the first surface 111a of the intermediate portion 111. However, the present application is not limited thereto, and the first duct 13 may be housed in another manner.

In some embodiments, in the carbon slide plate assembly 10, the bracket 11 may be provided with the bowed corner portion 112 on one longitudinal side of the middle portion 111, or, as shown in fig. 1, the bowed corner portions 112 may be provided on both longitudinal sides of the middle portion 111, respectively. In the case where the bracket 11 is provided with 2 arcuate corner portions 112, the second duct 14 may be provided in one of the arcuate corner portions 112, or may be provided in each of the two arcuate corner portions 112. The two second ducts 14 disposed in the two arcuate corners 112 may be of the same or different configurations.

In some embodiments, the second duct 14 may be disposed throughout the length of the bow 112. By arranging the second duct 14 over the entire range of the bow corner 112 in the longitudinal direction, breakage at any position of the bow corner 112 can be detected. The present application is not limited to this, and the second duct 14 may be arranged in a partial range in the longitudinal direction of the bow-corner 112.

In some embodiments, at least a portion of the second draft tube 14 may be housed within the bow corner 112. For example, the portion of the second duct 14 connected to the first junction 15 may be located within the middle portion 111. The present application is not limited thereto, and the second duct 14 may be entirely located within the range of the arcuate portion 112.

Fig. 4 is another cross-sectional view of a carbon skid assembly 10 in accordance with an embodiment of the present invention. Fig. 4 is a cross-sectional view taken along a section line BB' shown in fig. 1. As shown in fig. 4, at least a portion of the second flow conduit 14 may be disposed within the cavity 1121 of the bow corner 112. By accommodating the second flow duct 14 in the cavity 1121 of the bow 112, there is no need to additionally provide a component for accommodating the second flow duct 14, for example, there is no need to cover the surface of the bow 112 with carbon strips, which is beneficial to reducing the weight of the carbon slide assembly 10, saving carbon materials, and simplifying the structure.

In addition, since the second flow guide tube 14 is disposed in the cavity 1121 of the arcuate portion 112, the arcuate portion 112 protects the second flow guide tube 14 to a certain extent. When the bow corner 112 is damaged slightly without affecting the use, the second draft tube 14 is not broken; the second duct 14 is broken only when the bow corner 112 is largely damaged, which may affect the use of the device, and thus the bow lowering control can be more appropriately performed. The present application is not limited thereto, and the second duct 14 may be housed in another manner.

In some embodiments, as shown in fig. 2, the first and second fluid conduits 13, 14 may be coupled to a detection assembly (not shown) via a first adapter 15. Thereby, the first and second flow tubes 13 and 14 can be detected by the detection means.

In some embodiments, in the carbon skid assembly 10, the first connectors 15 may be respectively disposed at both ends of the first draft tube 13, or the first connectors 15 may be disposed at one end of the first draft tube 13 or other positions.

In the case where two first joints 15 are provided, the distance between the two first joints 15 may be a predetermined distance, and thus, the distance between the first joints 15 may be set to a uniform standard, which facilitates connection with other components such as a detection assembly. Both first connections 15 can be connected to the detection assembly, whereby the first and second flow conduits 13, 14 can be detected by means of both first connections 15. Alternatively, one of the two first connectors 15 may be connected to the detection assembly.

In some embodiments, as shown in fig. 2, a first connector 15 may be used to connect the first fluid conduit 13, the second fluid conduit 14, and the detection assembly when connecting the first fluid conduit 13 and the second fluid conduit 14 to the detection assembly. This reduces the number of parts of the carbon slide plate assembly 10, and simplifies the connection relationship.

In some embodiments, both the first and second flow conduits 13, 14 may be in communication through the first adapter 15, and the fluid in the first and second flow conduits 13, 14 can be detected by the detection assembly. By communicating the first draft tube 13 and the second draft tube 14, when the first draft tube 13 is broken, the fluid in the second draft tube 14 can also flow out through the broken part of the first draft tube 13, or, when the second draft tube 14 is broken, the fluid in the first draft tube 13 can also flow out through the broken part of the second draft tube 14, thereby improving the flow change and facilitating the detection assembly to detect the breakage of the first draft tube 13 and the second draft tube 14. The present application is not limited thereto, and the first flow guide tube 13 and the second flow guide tube 14 may not be communicated with each other as long as the first flow guide tube 13 and the second flow guide tube 14 can be detected by the detection assembly.

In some embodiments, the first fluid conduit 13 and the second fluid conduit 14 may also be connected to the detection assembly via different first connectors 15. Furthermore, the detection assembly connected to the first flow duct 13 and the detection assembly connected to the second flow duct 14 may be identical or different.

Next, the structure of the carbon skid plate assembly 10 will be described by way of example, in which the first flow pipe 13, the second flow pipe 14, and the detection assembly are connected by one first joint 15.

Fig. 5 is yet another cross-sectional view of a carbon skid assembly 10 in accordance with an embodiment of the present invention. Wherein fig. 5 is a sectional view taken along a sectional line CC' shown in fig. 1. In some embodiments, as shown in fig. 5, the first duct 13 is coupled to the first bore 151 of the first joint 15, the second duct 14 is coupled to the second bore 152 of the first joint 15, and the first bore 151 and the second bore 152 are disposed at different locations along the length of the first joint 15. In other words, the first hole 151 and the second hole 152 are different in position in the up-down direction.

By providing the first and second holes 151 and 152 at different positions in the longitudinal direction of the first joint 15, it is possible to make the first flow tube 13 more easily arranged between the carbon rod 12 and the first surface 111a of the bracket 11 and the second flow tube 14 more easily arranged inside the bracket 111, avoiding excessive bending of the first and second flow tubes 13 and 14 in the up-down direction.

For example, the lower edge of the first hole 151 may be substantially flush with the first surface 111a of the intermediate portion 111 of the bracket 11 in the vertical direction, and/or the opening range of the second hole 152 may be made to fall within the range of the cavity of the bracket 11 as viewed in the longitudinal direction of the bracket 11. The present application is not limited thereto, and the first hole 151 and the second hole 152 may be located at the same position in the vertical direction or at other positions of the first joint 15.

In some embodiments, the first adapter 15, the first duct 13, and the second duct 14 may be connected in various ways. For example, the connection is performed by welding, bonding, or the like, or by a connection member (for example, a second joint 143 described later). Alternatively, the first joint 15, the first duct 13, and the second duct 14 may be integrally molded, thereby improving the sealing property.

Fig. 6 is a schematic view of the first connector 15 and the second flow conduit 14 of the carbon skid assembly 10 according to an embodiment of the present invention. In some embodiments, as shown in fig. 6, the second flow conduit 14 may include: first pipe portion 141 and second pipe portion 142. Wherein the first tube part 141 may be connected to the first joint 15, the first tube part 141 may extend in a direction deviating from the center line O of the arcuate portion 112 as viewed in a direction perpendicular to the first surface 111a of the bracket 11. The second pipe portion 142 communicates with the first pipe portion 141 and is disposed in the cavity of the bow corner portion 112. By providing the second duct 14 with the curved first pipe portion 141, when another member is provided near the center line O of the arcuate corner portion 112, interference between the second duct 14 and another member can be avoided, and the second duct 14 can be accommodated in the bracket 11 having various configurations.

The present invention is not limited to this, and the first pipe portion 141 may extend in the direction of the center line O of the arcuate corner portion 112. This simplifies the structure of the second duct 14, and facilitates manufacture and assembly.

In some embodiments, the first tube portion 141 may be integrally formed with the second tube portion 142, thereby enabling improved containment of the second delivery tube 14. Alternatively, first pipe portion 141 may be formed separately from second pipe portion 142 and connected by welding, bonding, or the like, or may be connected by a connecting member.

In some embodiments, the first pipe portion 141 may be directly connected to the first joint 15, or the second duct 14 may further include a second joint 143. The second joint 143 may connect the first joint 15 and the first pipe part 141. Thereby, the assembly of the second duct 14 and the first joint 15 is facilitated.

In some embodiments, the second connector 143 may be directly connected to the first connector 15, or the second delivery tube 14 may further include a third tube portion 144, the first connector 15 being connected to the first connector 15 through the third tube portion 144. This further improves the ease of assembly.

In some embodiments, the inner diameter of the second flow conduit 14 can be the same as the inner diameter of the first flow conduit 13. By making the inner diameter of the second duct 14 equal to the inner diameter of the first duct 13, it is possible to connect the second duct 14 and the first joint 15, and the first duct 13 and the first joint 15, using a uniform connection technique (e.g., a uniform welding process, etc.), facilitating assembly.

In some embodiments, the second flow conduit 14 may also have a different inner diameter than the first flow conduit 13. This makes it possible to flexibly set the inner diameters of the second duct 14 and the first duct 13, and to adjust the volume of the second duct 14 and the volume of the first duct 13 according to actual conditions. Further, the amount of fluid contained in the second flow tube 14 and the first flow tube 13 can be adjusted.

For example, when the length of the second duct 14 is small, the inner diameter of the second duct 14 is set large, and the amount of fluid contained in the second duct 14 satisfies a predetermined requirement, whereby the speed of the fluid flowing out of the second duct 14 can be ensured when the second duct 14 breaks, and therefore, the change in the flow rate can be easily detected, and the sensitivity of the pantograph can be ensured. However, the present application is not limited thereto, and the inner diameter of the first guide tube 13 may be larger than the inner diameter of the second guide tube 14.

In some embodiments, the difficulty of the first and second fluid conduits 13 and 14 being broken can be flexibly adjusted by adjusting the wall thickness, the wall material, and the like of the first and second fluid conduits 13 and 14. Thus, the rationality of the pantograph control is further improved.

Fig. 7 is another schematic view of a partial structure of the carbon skid plate assembly 10 according to an embodiment of the present invention, and fig. 8 is another schematic view of a partial structure of the carbon skid plate assembly 10 according to an embodiment of the present invention. In some embodiments, as shown in fig. 7 and 8, the carbon slip sheet assembly 10 may further include a cover plate 16, the cover plate 16 being disposed on at least a portion of the second surface 112a of the arcuate corner 112, and the cover plate 16 may be located on at least one side of the length of the carbon strip 12. As shown in fig. 8, the extending direction of the end surface M of the cover plate 16 abutting the carbon rod 12 forms an angle α of a predetermined angle with the width direction of the carbon rod 12, as viewed in the direction (vertical direction) perpendicular to the first surface 111a of the carriage 11.

By setting the extending direction of the end surface M to be nonparallel to the width direction of the carbon rod 12, it is thereby possible to avoid the occurrence of steps due to abrasion of the carbon rod 12 at the portion where the carbon rod 12 abuts against the lid plate 16 in the process of rubbing the grid with the carbon rod 12. Thus, the service life of the carbon slide plate assembly 10 can be improved.

In some embodiments, the preset angle may be any angle greater than 0 ° and less than 90 °. For example, the preset angle may be 15 °. The present application is not limited thereto, and the end surface M of the cap plate 16 abutting the carbon rod 12 may have other shapes, for example, an arc shape, a zigzag shape, and the like.

According to the above embodiment, since the first draft tube 13 and the second draft tube 14 are disposed in the middle part 111 and the corner part 112 of the carbon slide plate assembly 10 of the pantograph, not only the state of the middle part 111 but also the state of the corner part 112 can be detected, and therefore, when the corner part 112 is damaged by an external force, the pantograph can be lowered in time, and the pantograph and the power grid in contact with the pantograph can be prevented from being further damaged. Further, by disposing the second flow pipe 14 inside the arcuate corner portion 112, it is not necessary to additionally provide a member for accommodating the second flow pipe 14, and for example, it is not necessary to cover the surface of the arcuate corner portion 112 with carbon strips, so that the amount of carbon material can be reduced, and the weight of the entire carbon slide assembly 10 can be reduced.

The embodiment of the utility model provides a pantograph is still provided. The pantograph includes the carbon sliding plate assembly according to the above embodiment, and since the structure of the carbon sliding plate assembly has been described in the above embodiment, the content thereof is incorporated herein, and will not be described again.
