DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Pantograph is an electrical device used by electric traction locomotives to obtain electric energy from the contact network. It is installed on the roof of the locomotive or EMU. Pantographs can be divided into single-arm pantographs and double-arm pantographs. Both are composed of a slide plate, an upper frame, a lower arm (a lower frame for double-arm pantographs), a chassis, a pantograph lifting spring, a transmission cylinder, a supporting insulator and other components. The diamond pantograph, also known as the diamond pantograph, was very common in the past, but was gradually eliminated due to its high maintenance cost and the fact that it was easy to break the contact network in the event of a fault. In recent years, single-arm pantographs have been used more often (see figure). The smoothness of the load current passing through the contact surface between the contact line and the pantograph slide plate is related to the contact pressure, transition resistance and contact area between the slide plate and the contact line, and depends on the interaction between the pantograph and the contact network.

[0048] Working principle:

[0049] Raise the bow

[0050] The compressed air enters the transmission cylinder evenly through the electro-pneumatic valve, and the cylinder piston compresses the bow-lowering spring in the cylinder. At this time, the bow-raising spring causes the lower arm to rotate, lifting the upper frame and the slide plate. The pantograph rises at a uniform speed, and there is a slow pause when it approaches the contact line, and then it quickly touches the contact line.

[0051] Bow Drop

[0052] The compressed air in the transmission cylinder is rapidly discharged into the atmosphere through the pantograph buffer valve. Under the action of the bow-lowering spring, the force of the bow-raising spring is overcome, causing the pantograph to drop rapidly and detach from the contact network.

[0053] Current receiving quality

[0054] The smoothness of the load current passing through the contact surface between the contact wire and the pantograph slide is related to the contact pressure, transition resistance and contact area between the slide and the contact wire, and depends on the interaction between the pantograph and the contact network.

[0055] In order to ensure the smooth flow of traction current, there must be a certain contact pressure between the pantograph and the contact wire. The actual contact pressure of the pantograph network consists of four parts: the vertical force applied by the pantograph lifting system to the slide plate is the static contact pressure (generally 70N or 90N); due to the elastic difference of the contact suspension itself, the contact line will rise to varying degrees under the action of the pantograph lifting, so that the pantograph will vibrate up and down during operation, and the pantograph will generate an alternating dynamic contact pressure related to its own calculated mass; the pantograph is affected by the air flow during operation, which generates an aerodynamic force that increases rapidly with the increase of speed; the damping force generated by each joint of the pantograph during the process of raising and lowering the pantograph.

[0056] The pantograph-net contact pressure can directly reflect the contact condition between the pantograph slide and the contact wire. It must conform to the normal distribution law and fluctuate within a certain range. If it is too small, the offline rate will increase; if it is too large, it will cause greater mechanical wear between the slide and the contact wire. In order to ensure that the pantograph has reliable current-collecting quality, the calculated mass of the pantograph should be reduced as much as possible, and the elastic uniformity of the contact suspension should be increased. The quality and electromechanical performance of the slide have a great influence on the current-collecting quality.

[0057] Classification

[0058] Pantographs are divided into four categories: double-arm, single-arm, vertical and Ishizu.

[0059] Double Arms

[0060] The double-arm pantograph is the most traditional pantograph, also known as the "diamond" pantograph, named after its diamond shape. However, due to the high maintenance cost and the risk of breaking the contact network in the event of a failure, some newly manufactured railway vehicles have switched to single-arm pantographs; some railway vehicles (such as the Shinkansen 300 series vehicles) have also been converted from the original double-arm pantograph to a single-arm pantograph.

[0061] Single arm

[0062] In addition to the double-arm type, there is also a single-arm pantograph, which can also be called a "Z" (Z) (ㄑ) shaped pantograph. The advantage of this type of pantograph is that it is quieter than the double-arm pantograph and is less likely to tear the contact network when a fault occurs. It is a more common type of pantograph. Depending on the design methods of each railway vehicle manufacturer, there will be some differences in the design of the pantograph.

[0063] Vertical

[0064] In addition to the above two types of pantographs, some pantographs are designed vertically, also known as "T"-shaped (also called wing-shaped) pantographs. Their low wind resistance is particularly suitable for high-speed driving to reduce noise during driving. Therefore, this type of pantograph is mainly used for high-speed railway vehicles. However, due to the high cost, vertical pantographs are no longer used (the Japanese Shinkansen 500 series was modified from a vertical pantograph to a single-arm pantograph).

[0065] Ishizu style

[0066] The sixth-generation president of Japan's Okayama Electric Rail, Ryusuke Ishizu, invented it in 1951 and it is also known as the "Okayama Electric Rail" and "Okayama Rail Rail".

[0067] In the related technology, a T-shaped pantograph mounting structure on a roof includes a pantograph base, a pantograph connecting arm is fixedly connected to the pantograph base, a pantograph sliding plate is fixedly connected to the top of the pantograph connecting arm, two supporting insulators are fixedly connected to the bottom of the pantograph base, a T-shaped mounting block is fixedly connected to the bottom of each supporting insulator, a roof is provided below the pantograph base, two slide grooves are provided on the roof, two T-shaped mounting blocks are respectively inserted into the slide grooves, and a mounting mechanism is provided on the roof.

[0068] The mounting mechanism comprises a T-shaped rotating rod which passes through the roof and is rotatably connected thereto, a driving bevel gear is fixedly connected to the bottom of the T-shaped rotating rod, the driving bevel gear is meshed with two driven bevel gears, the two driven bevel gears are fixedly connected to a threaded rod, the two threaded rods are rotatably connected to the roof, the outer walls of the two threaded rods are sleeved with slides which are threadedly connected thereto, the two slides are slidably connected to the roof, the opposite ends of the two slides are fixedly connected to two positioning blocks, each positioning block passes through the roof and is slidably connected thereto, each T-shaped mounting block is provided with two positioning grooves, and each positioning block is respectively inserted into the positioning groove and arranged.

[0069] Both ends of the supporting insulator are installed and fixed to the pantograph base and the T-shaped mounting block by welding.

[0070] The outer wall of the T-shaped rotating rod is covered with a protective cover, and the material of the protective cover is insulating rubber.

[0071] A through hole is penetrated on the slide plate, and the outer wall of the threaded rod and the inner wall of the slide plate are respectively provided with matched external threads and internal threads.

[0072] The cross section of the slide plate is arranged in a square shape.

[0073] The advantages of this solution are:

[0074] 1. The staff holds the T-shaped rotating rod and rotates it to drive the active bevel gear, two driven bevel gears and threaded rod to rotate, so that the slides and positioning blocks on both sides move away from each other until the positioning block is inserted into the positioning groove, completing the installation and fixation of the T-shaped mounting block, and realizing the installation and fixation of the pantograph on the roof. The operation is simple and saves installation time.

[0075] 2. The staff holds the T-shaped rotating rod and rotates it in reverse to drive the active bevel gear, two driven bevel gears and threaded rod to rotate in reverse, so that the slides and positioning blocks on both sides move relatively, until the positioning block is out of the positioning groove, the T-shaped mounting block can be slid out of the slide groove, thereby realizing the disassembly of the pantograph and facilitating its maintenance.

[0076] In summary, the pantograph can be installed or disassembled through the installation mechanism, and when the pantograph is damaged, the disassembly and installation can be completed quickly, ensuring that the vehicle's itinerary is scheduled on time.

[0077] A roof pantograph mounting structure includes a groove portion arranged on the roof for mounting the pantograph, a base is arranged inside the groove portion, the base is fixedly connected to the vehicle body, the bottom of the pantograph is fixedly mounted on the base, and a sound insulation board is also arranged between the base and the bottom of the pantograph.

[0078] The base is an H-shaped frame structure.

[0079] A counterweight block is arranged on the base and is fixed on the base through a fastener.

[0080] The sound insulation board consists of two layers of metal plates, upper and lower, and the sound insulation material in the middle.

[0081] A plurality of micro-perforated plates are installed on the lower surface of the sound insulation board.

[0082] A plurality of micro-perforated plates are arranged parallel to each other in the vehicle length direction, and a reinforcing rib is fixed between every two adjacent micro-perforated plates, and the reinforcing rib is fixed on the sound insulation plate.

[0083] The cross section of the microporous plate is U-shaped, and both sides of the microporous plate are provided with flanges fixedly connected with the sound insulation board.

[0084] The shape of the sound insulation board matches the shape of the groove part and completely covers the groove part. The sound insulation board is fixedly connected to the base and the vehicle body at the same time.

[0085] A circle of pressure strips is arranged around the sound insulation board to adjust the gap between the sound insulation board and the vehicle body at the groove part.

[0086] The sound insulation board is fixedly connected to the vehicle body through a vibration-damping seat.

[0087] The advantage of this solution is that the pantograph is completely installed inside the groove of the roof, which can not only effectively reduce the impact of airflow excitation of the pantograph system and the generation of aerodynamic noise, but also make the vehicle appearance more smooth and beautiful. In addition, the pantograph is fixed to the steel structure through a base, which is not only convenient for installation and maintenance, but also avoids direct connection between the pantograph and the steel structure. A layer of sound insulation board is set between the pantograph and the base, which can effectively reduce the transmission of structure-borne noise into the car, and at the same time can better isolate air noise, which plays a good role in absorbing and reducing aerodynamic noise and structure-borne noise in the pantograph area of ​​high-speed railway passenger cars.

[0088] The camshaft is an axially-coupled device for arranging the axes of rotation of the axes of rotation of the carbon skateboard and of the axes of rotation of the carbon skateboard. A set of springs is arranged between the upper inlay block and the support block. A set of airbag driving devices for driving the pantograph body is installed near one side of the base. Three sets of insulators are arranged at the bottom of the base. The insulators are fixedly installed at the bottom of the base, and a set of mounting blocks are fixedly arranged at the lower ends of the insulators. The advantage of this solution is that the connecting seat can be fixedly connected to the carbon slide board on the bottom surface first, and then the carbon slide board with the connecting seat installed can be replaced as a whole. When replacing and installing the carbon slide board, the upper mosaic block is embedded in the upper mosaic groove and the lower mosaic block is embedded in the lower mosaic groove. At this time, the upper mosaic block is aligned with the side positioning block, and the fastening block and the side positioning block are fixedly connected by fastening screws to complete the installation of the carbon slide board. The fastening screws designed here are fixed from the side, which can avoid fixing from the bottom like the previous installation method. There are no obstacles when fixing from the side, which is easy to operate and more practical during installation. In addition, a group of springs are set between the support block and the fastening block to play a supporting role. Since the support block will be pressed down and deformed when the slide board contacts the cable, the springs set between the support block and the fastening block can improve the toughness of the entire structure, which can prevent the support block from being pressed and deformed.

[0089] A novel locomotive pantograph mounting structure comprises a mounting seat, an arc-shaped plate, a mounting plate, a drainage mechanism and a fixed mounting mechanism; wherein the top side surface of the mounting seat is fixedly connected with the arc-shaped plate, and the top side of the arc-shaped plate is fixedly connected with the mounting plate;

[0092] There are two mounting plates, which are located on two opposite sides of the top of the arc-shaped plate, and a plurality of mounting holes are evenly opened on the surfaces of the mounting plates.

[0093] There are several guide grooves, and adjacent guide grooves are evenly distributed with equal distances. One end of the guide groove is in contact with the contact surface of the arc plate, and the other end of the guide groove is connected with the drainage groove.

[0094] A through hole is opened on the surface of the magnet block, a drain pipe is slidably connected in the through hole, a clamping plate is attached to the top side of the drain pipe, and the top side of the clamping plate is threadedly connected to the end of the fastening bolt on the surface of the magnet block for rotational connection.

[0095] The bottom surfaces on opposite sides of the installation plate are both fixedly connected with reinforcement plates, and the two reinforcement plates are placed parallel to each other.

[0096] The top side surface of the base supporting the insulator of the pantograph body is threadedly connected with fixing bolts at four corner positions, and the ends of the fixing bolts are threadedly connected with the mounting holes on the surface of the mounting plate.

[0097] The advantage of this solution is that

The elastic force of the thrust spring 18 is greater than the gravity of the base 3, thereby ensuring the stability of the connection; when disassembly is required, the connecting column 13 is rotated by a tool, and the support plate 21 pushes the base 3. When the second limit block 15 falls into the aisle, the connecting column 13 is separated from the connecting sleeve 2, and the disassembly is completed.

[0128] The pantograph installation structure of the present invention is simple to install and disassemble, convenient and quick, reduces the disassembly time of the pantograph, and reduces the impact of pantograph maintenance on vehicle travel arrangements.

[0136] In order to prevent noise / device damage caused by the bumps of the vehicle during use, a damping member is arranged between the inner wall of the mounting seat 1 and the outer wall of the base 3. A step hole 5 is opened on the side wall of the mounting seat 1, and a bolt 4 is passed through the step hole 5. The bolt 4 passes through the mounting seat 1 and is fixedly connected to the damping sleeve 6. The third slide bar 24 is fixedly connected to the outer wall of the base 3 through the connecting member 7. When vibration occurs, the base 3 drives the third slide bar 24 to slide in the damping sleeve 6 through the connecting member 7, and then drives the damping block 9 to slide in the damping sleeve 6. The damping fluid flows through the flow channel 901 to generate viscosity, consume energy, and reduce vibration.
