Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to a welding type carbon slide plate. Background Art

[0002] The pantograph is an electrical device that electric traction locomotives use to obtain electricity from the contact network. It is installed on the roof of the locomotive or EMU. The carbon slide plate is a part installed on the top of the pantograph and in contact with the wire. The carbon slide plate has excellent conductivity and wear resistance, which can ensure the stability and efficiency of current transmission, while reducing wear on the contact network and ensuring the safe operation of the locomotive.

[0003] There are various ways to directly connect the pantograph and the carbon slide plate. Some trains use multiple sets of parts to assemble the carbon slide plate and the pantograph to facilitate the replacement of the carbon slide plate. Some trains use welding to fix the carbon slide plate and the pantograph. This makes the connection between the carbon slide plate and the pantograph tighter, which can further ensure the transmission and stability of the current.

[0004] However, when replacing the current welded carbon slide plate, since the pantograph and the carbon slide plate are welded together, the carbon slide plate and the pantograph need to be disassembled and replaced together. The existing disassembly and installation method requires the use of disassembly tools and a large number of screws, bolts and other parts, which has low disassembly and installation efficiency and may also cause parts to be lost. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology, when the current welded carbon slide plate is replaced, since the pantograph and the carbon slide plate are welded, the carbon slide plate and the pantograph need to be disassembled and replaced together. The existing disassembly and installation method requires the use of disassembly tools and a large number of screws, bolts and other parts. The disassembly and installation efficiency is low and it may also lead to the problem of parts loss. The utility model proposes a welded carbon slide plate.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the utility model describes a welding type carbon skateboard, including a pantograph, the top of the pantograph is fixedly connected to the carbon skateboard, the top of the carbon skateboard is provided with an electric wire, the two ends of the bottom of the pantograph are fixedly connected to a U-shaped seat, the bottom end of the U-shaped seat is provided with a fixing mechanism, the fixing mechanism includes a fixing seat, the fixing seat is provided at the bottom end of the U-shaped seat, a movable groove is provided at the top of the fixing seat, the two ends of the movable groove are rotatably connected with screws, a hexagonal column is provided at one end of the fixing seat, and the output shaft of the hexagonal column passes through the fixing seat and is fixedly connected to one end of one group of screws, the outer sides of the two ends of the screw are rotatably connected with movable blocks, and one side of the movable block is fixedly connected with multiple groups of fixed rods.

[0007] Preferably, the bottom end of the U-shaped seat is inserted into the movable groove, positioning rods are provided on both sides of the U-shaped seat, and two groups of positioning rods are fixedly connected to the top of the fixed seat, and multiple groups of fixing holes are opened inside the U-shaped seat, the size of the fixing holes is adapted to the size of the fixing rods, and the fixing holes are horizontally aligned with the fixing rods.

[0008] Preferably, a blocking column is fixedly connected to the outer side of the middle portion of the screw, and the threads formed at both ends of the screw are opposite.

[0009] Preferably, the moving block is inside the moving groove, and the size of the moving block is adapted to the moving groove.

[0010] Preferably, a protective mechanism is provided at one end of the fixing seat close to the hexagonal column, and the protective mechanism includes two groups of compression grooves, and the two groups of compression grooves are arranged on both sides of the hexagonal column, the compression grooves are opened on one side of the fixing seat, and long rods are fixedly connected at both ends of the compression grooves.

[0013] 1. The utility model realizes the function of inserting the U-shaped seat at the bottom end of the pantograph into the corresponding movable groove through the structural design of the fixing mechanism, rotating the hexagonal column to drive the screw to rotate, thereby moving the two sets of movable blocks and inserting the fixing rod on one side of the movable block into the fixing hole inside the U-shaped seat to complete the fixing function. This solves the problem of the existing welded carbon slide plate that when replacing the pantograph and the carbon slide plate, the carbon slide plate and the pantograph need to be disassembled and replaced together due to the welding between the pantograph and the carbon slide plate. The existing disassembly and installation method requires the use of disassembly tools and a large number of parts such as screws and bolts, which has low disassembly and installation efficiency and may also lead to the problem of parts loss, thereby improving the efficiency of installation and disassembly of the pantograph and the carbon slide plate.

[0014] 2. The utility model realizes, through the structural design of the protection mechanism, that when the slider and the protective shell are not subjected to external force, the elastic force of the spring will push the slider to the end of the long rod close to the hexagonal column. When the hexagonal column is rotated until the fixing rod is inserted into the fixing hole, the hexagonal column can be fine-tuned to cooperate with the spring so that the two sets of protective shells can be tightly attached to the outside of the hexagonal column. At this time, the hexagonal column cannot be easily rotated. This solves the problem that when the fixing rod is inserted into the fixing hole, in order to prevent external vibrations from causing the hexagonal column to rotate, thereby causing the screw rod to rotate and the fixing rod to disengage from the fixing hole, thereby improving the safety of the fixing mechanism.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 - Figure 4As shown, a welded carbon skateboard comprises a pantograph 1, the top of the pantograph 1 is fixedly connected to a carbon skateboard 2, the top of the carbon skateboard 2 is provided with a wire 3, the two ends of the bottom of the pantograph 1 are fixedly connected to a U-shaped seat 4, the bottom of the U-shaped seat 4 is provided with a fixing mechanism, the fixing mechanism comprises a fixing seat 5, the fixing seat 5 is provided at the bottom of the U-shaped seat 4, the top of the fixing seat 5 is provided with a movable groove 6, the two ends of the movable groove 6 are rotatably connected to a screw 7, one end of the fixing seat 5 is provided with a hexagonal column 8, and the output shaft of the hexagonal column 8 passes through the fixing seat 5 and is fixedly connected to one end of one group of screws 7, the outer sides of the two ends of the screw 7 are rotatably connected to a movable block 9, and one side of the movable block 9 is fixedly connected to multiple groups of fixed rods 10;

[0023] During operation, when the carbon slide plate 2 and pantograph 1 need to be replaced, they are removed from the fixing mechanism of the top bracket of the train, and then a new carbon slide plate 2 and pantograph 1 are replaced, and the U-shaped seat 4 at the bottom end of the pantograph 1 is inserted into the movable groove 6 between the two sets of positioning rods 12. At this time, the fixing hole 11 inside the U-shaped seat 4 is aligned with the fixing rod 10 on one side of the movable plate. When both sets of U-shaped seats 4 are inserted into the corresponding movable grooves 6, open the protective shell 16 on the outside of the corresponding hexagonal column 8 and rotate the hexagonal column 8 correctly. At this time, the screw 7 rotates and the movable plates at both ends of the screw 7 drive the fixed column to move toward the U-shaped seat 4. When the fixed column is inserted into the fixing hole 11, the fixation of the pantograph 1 and the fixing mechanism is completed.

[0024] Further, such as Figure 2 and Figure 3 As shown, the bottom end of the U-shaped seat 4 is inserted into the movable groove 6, and positioning rods 12 are provided on both sides of the U-shaped seat 4, and two groups of positioning rods 12 are fixedly connected to the top of the fixed seat 5. A plurality of fixing holes 11 are provided inside the U-shaped seat 4, and the size of the fixing holes 11 is adapted to the size of the fixing rods 10, and the fixing holes 11 are horizontally aligned with the fixing rods 10;

[0025] During operation, two sets of positioning rods 12 can enable the staff to determine the position of the U-shaped seat 4 when installing it, so that the fixing hole 11 inside the U-shaped seat 4 is aligned with the fixing rod 10. When the U-shaped seat 4 is installed, the hexagonal column 8 can be rotated so that the corresponding fixing rod 10 is inserted into the fixing hole 11 inside the U-shaped column, completing the fixation of the fixing mechanism to the pantograph 1 and the carbon slide plate 2.

[0026] Further, such as Figure 3 As shown, a blocking column 100 is fixedly connected to the outer side of the middle portion of the screw rod 7, and the threads opened at both ends of the screw rod 7 are opposite;

[0027] During operation, the threads at both ends of the screw 7 are opposite, so the rotation of the screw 7 can make the moving blocks 9 at both ends of the screw 7 move toward each other, so that the fixing rods 10 on the side of the two sets of moving blocks 9 close to the U-shaped seat 4 can be inserted into the fixing holes 11, and the blocking column 100 can collide with the fixing rods 10 when the U-shaped seat 4 is not placed inside the moving groove 6.

[0028] Further, such as Figure 3 As shown, the moving block 9 is inside the moving groove 6, and the size of the moving block 9 is adapted to the moving groove 6;

[0029] During operation, the rotation of the screw 7 will tend to drive the moving block 9 to rotate. Since the size of the moving block 9 is adapted to the moving groove 6, the tendency of the moving block 9 and the screw 7 to rotate together is hindered by the moving groove 6. At this time, through the characteristics of the threaded connection of the screw 7, the rotation of the screw 7 can drive the moving block 9 to move.

[0030] Further, such as Figure 3 and Figure 4 As shown, a protective mechanism is provided at one end of the fixing seat 5 close to the hexagonal column 8, and the protective mechanism includes two groups of compression grooves 13, and the two groups of compression grooves 13 are provided on both sides of the hexagonal column 8. The compression groove 13 is opened on one side of the fixing seat 5, and a long rod 14 is fixedly connected to the two ends of the compression groove 13. A slider 15 is sleeved on the outside of the long rod 14, and a protective shell 16 is fixedly connected to one side of the slider 15. One side of the protective shell 16 is in close contact with the outer side of the hexagonal column 8;

[0031] During operation, the structural design of the protection mechanism ensures that when the slider 15 and the protective shell 16 are not subjected to external force, the elastic force of the spring 17 will push the slider 15 to the end of the long rod 14 close to the hexagonal column 8. When the hexagonal column 8 is rotated until the fixing rod 10 is inserted into the fixing hole 11, the hexagonal column 8 can be fine-tuned to cooperate with the spring 17 so that the two sets of protective shells 16 can be close to the outside of the hexagonal column 8. At this time, the hexagonal column 8 cannot be easily rotated, which solves the problem that when the fixing rod 10 is inserted into the fixing hole 11, in order to prevent external vibrations from causing the hexagonal column 8 to rotate, thereby causing the screw 7 to rotate and the fixing rod 10 to disengage from the fixing hole 11, thereby improving the safety of the fixing mechanism.

[0032] Further, such as Figure 4 As shown, a spring 17 is sleeved on the outside of the long rod 14, and both ends of the spring 17 are fixedly connected to the slider 15 and the compression groove 13;

[0033] During operation, the spring 17 can keep the slider 15 and the protective shell 16 at the end of the long rod 14 close to the hexagonal column 8 without external force, thereby cooperating with the two sets of protective shells 16 to cling to the outside of the hexagonal column 8 to complete further protection measures for the hexagonal column 8.

[0034] Working principle: when the carbon slide plate 2 and pantograph 1 need to be replaced, remove them from the fixing mechanism of the top bracket of the train, and then replace the new carbon slide plate 2 and pantograph 1, and insert the U-shaped seat 4 at the bottom end of the pantograph 1 into the movable groove 6 between the two sets of positioning rods 12. At this time, the fixing hole 11 inside the U-shaped seat 4 is aligned with the fixing rod 10 on one side of the movable plate. When both sets of U-shaped seats 4 are inserted into the corresponding movable grooves 6, open the protective shell 16 on the outside of the corresponding hexagonal column 8 and rotate the hexagonal column 8 correctly. At this time, the screw 7 rotates and the movable plates at both ends of the screw 7 drive the fixed column to move toward the U-shaped seat 4. When the fixed column is inserted into the fixing hole 11, the fixation of the pantograph 1 and the fixing mechanism is completed. At this time, fine-tune the hexagonal column 8 so that the protective shell 16 can be close to the outside of the hexagonal column 8.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
