Description

Technical Field

[0001] This invention relates to the field of safety protection equipment for railway engineering vehicles, and in particular to an electrostatic shielding protection device for long rail train sets. Background Technology

[0002] Long rail trainsets are mainly used for loading, transporting, unloading, and related track construction and maintenance work on long rails. When loading, unloading, and unlocking long rails in electrified railway sections, workers typically need to operate on the upper part of the trainset or in the rail-bearing area. Because the area above the trainset is adjacent to the electrified overhead contact line, workers are susceptible to electrostatic induction and high-voltage electric fields during high-altitude operations, which can pose serious safety risks such as discharge and flashover. Therefore, long rail trainsets usually require electrostatic shielding devices that create an isolated protective area above the workers.

[0003] Existing shielding and protective devices for long rail train sets mostly employ a protective canopy in conjunction with lifting or tilting mechanisms to change the canopy's position under different operating conditions. However, in actual rail loading, transporting, and unloading operations, the protective canopy needs to reliably cover the work area when in protective mode, while also avoiding space for rail movement and hoisting operations during loading and unloading. Simultaneously, the protective canopy needs to be retracted to a position that does not affect the vehicle's clearance when the vehicle is in motion. In existing structures, the transmission relationship between the protective canopy's translational, tilting, and lifting actions is not tight enough. Some structures rely on manual pushing or simple guide sliding, which easily leads to problems such as unstable movement, asynchrony between the two sides, and swaying or jamming during operation, affecting the rapid switching and reliable resetting of the protective canopy between multiple operating conditions.

[0004] Furthermore, protective canopies typically have large lateral dimensions and a certain weight. If relying solely on unilateral guidance or single-point drive, they are prone to uneven loading during translation or tilting. If the connection structure between the protective canopy and the vehicle body mounting position is not stable enough, it may also lead to loosening between the insulating protective plate and the canopy's steel frame, thus affecting the long-term reliability of the electrostatic shielding protection device. Therefore, it is necessary to provide an electrostatic shielding protection device with a clear structural connection, stable lifting and translation, reliable tilting and obstacle avoidance, and suitable for the operating conditions of long-rail train sets. Summary of the Invention

[0005] The purpose of this invention is to provide an electrostatic shielding protection device for long rail train sets. By setting a vertically lifting guide column on a fixed support frame, and setting a rack-and-pinion translation structure at the top of the lifting guide column that can drive the protective canopy to move laterally, and by using a flip support seat, bushing, flip shaft and flip drive motor to form an overall flip structure of the protective canopy, the protective canopy on one side can be switched between a horizontal protection position and a flipped avoidance position, thereby meeting the requirements of long rail train sets for electrostatic shielding, protective canopy avoidance and vehicle clearance adaptation under different operating conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An electrostatic shielding protection device for long rail train sets includes a fixed support frame installed on the car body of the long rail train set. A lifting guide column is slidably mounted on the fixed support frame along the vertical direction. The lifting guide column is equipped with a vertical rack. A lifting drive gear that meshes with the vertical rack is installed on the fixed support frame. When the lifting drive gear rotates, it drives the lifting guide column to rise and fall relative to the fixed support frame through the vertical rack.

[0007] The top of the lifting guide column is provided with a translation mounting seat, and a baffle extending laterally along the long rail train is formed on the translation mounting seat. The baffle has two side plates arranged opposite each other and a top plate connected between the two side plates. A slide rail is provided between the two side plates, and a horizontal rack is slidably arranged in the slide rail. At least one of the side plates is provided with a translation drive motor. The output end of the translation drive motor meshes with the horizontal rack through a translation drive gear to drive the horizontal rack to translate laterally along the slide rail.

[0008] The bottom of the baffle is connected to a flip support seat, and a bushing is provided on the flip support seat. A flip shaft is rotatably inserted inside the bushing. A flip drive motor is also provided on the flip support seat. The flip drive motor drives the flip shaft to rotate through a gear transmission assembly, so as to drive the single-sided protective shed to flip as a whole between a horizontal protective position and a flip avoidance position.

[0009] The single-sided protective shed has a steel frame and an insulating protective plate laid on the steel frame. The outer periphery of the steel frame is provided with a frame beam, which is fixed to both ends of the horizontal rack by clamping members.

[0010] Preferably, the insulating protective board is an epoxy glass cloth laminate, and an insulating pad is provided between the insulating protective board and the steel frame of the shed.

[0011] Preferably, the fixed support frame is provided with a vertical guide column seat, the lifting guide column is slidably disposed along the vertical guide column seat, the vertical rack is fixed to one side of the lifting guide column and rises and falls synchronously with the lifting guide column; the lifting drive gear is fixed in position relative to the fixed support frame, and the lifting drive gear limits the lifting path of the lifting guide column through meshing transmission with the vertical rack.

[0012] Preferably, the fixed support frame is provided with two sets of vertical guide column seats at transverse intervals along the long rail train set. Each set of vertical guide column seats is provided with a lifting guide column, a vertical rack and a vertical guide column seat. The two sets of vertical racks are respectively engaged with the corresponding lifting drive gears. The two lifting drive gears are connected by a synchronous transmission shaft. The synchronous transmission shaft is driven by the same lifting drive motor so that the two sets of lifting guide columns are raised and lowered synchronously.

[0013] Preferably, the gear transmission assembly has a driving gear connected to the output end of the flip drive motor and a driven gear connected to the flip shaft. The driving gear meshes with the driven gear, and the flip drive motor drives the flip shaft to rotate relative to the bushing through the driving gear and the driven gear.

[0014] Preferably, the horizontal rack has a guide section located within the slide rail and a rack section meshing with the translation drive gear. The guide section is slidably engaged with the slide rail. The translation drive motor is connected to the translation drive gear via a reducer to drive the horizontal rack to translate along the slide rail.

[0015] Preferably, two sets of translational guide components are spaced apart along the width direction of the single-sided protective canopy. Each set of translational guide components has the baffle, the slide rail, and the horizontal rack. A transverse synchronous shaft is provided between the two sets of translational guide components. The transverse synchronous shaft is formed by at least two shaft segments coaxially connected by a coupling. One end of the transverse synchronous shaft is connected to a translational drive motor located on one side of one set of translational guide components. A translational drive gear is provided on the transverse synchronous shaft corresponding to the position of each horizontal rack. Each translational drive gear meshes with the corresponding horizontal rack. When the translational drive motor drives the transverse synchronous shaft to rotate, the transverse synchronous shaft drives the translational drive gears on both sides to rotate synchronously, so that the horizontal racks on both sides extend or retract synchronously along the corresponding slide rails.

[0016] The beneficial effects of this invention are as follows: The invention uses a combination of lifting guide columns, vertical racks, and lifting drive gears to adjust the height of the protective canopy via gears on a fixed support frame, facilitating switching between different working heights. The translation structure employs a combination of baffles, slide rails, and horizontal racks, with the horizontal rack moving laterally within the guide space defined by the baffles, reducing sway and external interference during translation. The rotating support, bushings, rotating shaft, and rotating drive motor work together to allow a single-sided protective canopy to rotate as a whole around a defined axis, facilitating the formation of an electrostatic shielding protection zone above workers at the horizontal protection position and providing space for loading and unloading long rails at the rotating avoidance position. Simultaneously, the insulating protective plate laid on the canopy's steel frame and fixed by frame beams and clamping components improves the overall strength and insulation stability of the protective canopy, thereby enhancing the safety and operational efficiency of long rail trains operating on electrified railway sections.

[0026] The specific embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the following embodiments are used to illustrate the structural composition and working principle of the present invention and do not constitute a limitation on the scope of protection of the present invention. Without departing from the concept of the present invention, those skilled in the art can make adaptive adjustments to the dimensions, installation direction, and drive form of each component according to the car body mounting position, vehicle clearance, and operating space of different models of long-rail train sets.

[0027] like Figures 1 to 7 As shown, this embodiment provides an electrostatic shielding protection device for long rail train sets. The device is installed on the car body mounting position of the long rail train set and can be raised, lowered, moved laterally, and rotated as needed during the rail assembly, transport, or unloading operations of the long rail train set.

[0028] A fixed support frame 1 is fixedly installed on the car body of the long rail car group. The fixed support frame 1 serves as the bearing foundation of the entire electrostatic shielding protection device and can be installed at the corresponding position of the long rail car group by bolt connection or welding connection.

[0029] The fixed support frame 1 is preferably formed by combining I-beams to ensure that the lifting guide and drive components have a stable installation reference. Two fixed support frames 1 with I-beam structures are set along the width of the single-sided protective canopy.

[0030] A lifting guide column 2 is vertically slidably installed on the fixed support frame 1.

[0031] The lifting guide column 2 is used to support the translational mounting base 5, the flipping support base 11 and the single-sided protective canopy 16 above it, and moves up and down relative to the fixed support frame 1 under the action of lifting drive.

[0032] The lifting guide column 2 is provided with a vertical rack 3. The vertical rack 3 can be fixed on one side of the lifting guide column 2, or it can be processed or assembled with the lifting guide column 2 as a whole.

[0033] A lifting drive gear 4 is provided on the other side of the fixed support frame 1, and the lifting drive gear 4 meshes with the vertical rack 3. The position of the lifting drive gear 4 remains fixed relative to the fixed support frame 1. When the lifting drive gear 4 rotates, it drives the vertical rack 3 to move vertically through meshing with the vertical rack 3, thereby driving the lifting guide column 2 to rise and fall relative to the fixed support frame 1.

[0034] To ensure the straightness and stability of the lifting guide column 2 during the lifting process, a vertical guide column seat 18 is provided on the fixed support frame 1, and the lifting guide column 2 is slidably arranged along the vertical guide column seat 18.

[0035] In a specific embodiment, the vertical guide column seat 18 is configured as a guide structure composed of a guide groove, which is semi-circular and fixed to the fixed support frame 1 by bolts; the lifting guide column 2 and the vertical guide column seat 18 are in sliding fit.

[0036] The vertical rack 3 is fixed to one side of the lifting guide column 2 and rises and falls synchronously with the lifting guide column 2. The lifting drive gear 4 limits the lifting path of the lifting guide column 2 through meshing with the vertical rack 3, so that the lifting guide column 2 can move vertically stably on the fixed support frame 1.

[0037] In a preferred embodiment, the fixed support frame 1 is provided with two sets of vertical guide column seats 18 spaced laterally along the long rail train set. Each set of vertical guide column seats 18 is provided with a lifting guide column 2 and a vertical rack 3. The two sets of vertical racks 3 respectively mesh with the corresponding lifting drive gears 4. The two lifting drive gears 4 are connected by a synchronous transmission shaft 19, which is driven by the same lifting drive motor 20.

[0038] After the lifting drive motor 20 outputs power, it simultaneously drives the two lifting drive gears 4 to rotate via the synchronous transmission shaft 19, causing the two sets of lifting guide columns 2 to rise and fall synchronously. This structure can reduce the off-center load caused by unilateral lifting, reduce the risk of tilting of the unilateral protective canopy 16 during the lifting process, and ensure the smooth lifting and lowering of the protective canopy.

[0039] A translational mounting base 5 is provided at the top of the lifting guide column 2. The translational mounting base 5 is used to install the horizontal translation structure and to transfer the vertical displacement of the lifting guide column 2 to the upper translation structure and protective canopy structure. A baffle 6 extending laterally along the long rail train is formed on the translational mounting base 5. The baffle 6 has two opposing side plates 61 and a top plate 62 connecting the two side plates 61. The two side plates 61 and the top plate 62 together form a guide space for accommodating and protecting the horizontal rack 8, making it less susceptible to interference from external foreign objects during the lateral movement of the horizontal rack 8, and also reducing the possibility of vertical warping or lateral swaying of the horizontal rack 8.

[0040] A slide rail 7 is provided between the two side plates 61. The slide rail 7 is a sliding guide structure of a groove-shaped guide rail extending laterally. A horizontal rack 8 is slidably arranged inside the slide rail 7, and the horizontal rack 8 can be translated laterally relative to the baffle 6 along the slide rail 7. At least one side plate 61 is provided with a translation drive motor 9, and the output end of the translation drive motor 9 meshes with the horizontal rack 8 through a translation drive gear 10. After the translation drive motor 9 is started, the translation drive gear 10 rotates, and the translation drive gear 10 pushes the horizontal rack 8 to extend or retract laterally along the slide rail 7 through the meshing action with the horizontal rack 8. With the above structure, the lateral position of the single-sided protective canopy 16 can be adjusted with the horizontal rack 8 to meet the different requirements of the protective canopy position in the protection state and the avoidance state.

[0041] In specific implementation, the horizontal rack 8 has a guide section 81 located within the slide rail 7 and a rack section 82 that meshes with the translation drive gear 10. The guide section 81 is slidably engaged with the slide rail 7 to ensure that the horizontal rack 8 translates in a predetermined direction; the rack section 82 is provided with teeth that mesh with the translation drive gear 10. The translation drive motor 9 can be connected to the translation drive gear 10 via a reducer 21, so that the translation drive gear 10 drives the horizontal rack 8 to move at a suitable speed and output torque. The reducer 21 is a gear reducer, worm gear reducer, or other reduction mechanism suitable for railway vehicle equipment.

[0042] In another preferred embodiment, two sets of translational guide components 22 are spaced apart along the width direction of the single-sided protective canopy 16. Each set of translational guide components 22 has a baffle 6, a slide rail 7, and a horizontal rack 8. A transverse synchronous shaft 23 is provided between the two sets of translational guide components 22. The transverse synchronous shaft 23 is formed by at least two shaft segments coaxially connected by a coupling 24.

[0043] One end of the transverse synchronous shaft 23 is connected to a translation drive motor 9 located on one side of one set of translation guide components 22. A translation drive gear 10 is provided on the transverse synchronous shaft 23 corresponding to the position of each horizontal rack 8, and each translation drive gear 10 meshes with the corresponding horizontal rack 8. When the translation drive motor 9 drives the transverse synchronous shaft 23 to rotate, the transverse synchronous shaft 23 drives the translation drive gears 10 on both sides to rotate synchronously, causing the horizontal racks 8 on both sides to extend or retract synchronously along the corresponding slide rails 7.

[0044] By using the transverse synchronous shaft 23 and coupling 24, the synchronous movement of the horizontal racks 8 on both sides can be achieved when using a single-sided translation drive motor 9, thereby avoiding the situation where one end of the protective canopy 16 moves ahead and the other end lags behind when it moves laterally.

[0045] A flip support 11 is connected to the bottom of the baffle 6. Specifically, the flip support 11 is located at the bottom of the baffle 6 at the position corresponding to the moving end of the horizontal rack 8.

[0046] A bushing 12 is provided on the flip support 11, and a flip shaft 13 is rotatably inserted inside the bushing 12. The flip shaft 13 is arranged along the flip axis direction of the single-sided protective canopy 16, and a rotatable support relationship is formed between the flip shaft 13 and the bushing 12.

[0047] A tilting drive motor 14 is also provided on one side of the tilting support 11. The tilting drive motor 14 drives the tilting shaft 13 to rotate via a gear transmission assembly 15. The gear transmission assembly 15 has a driving gear 151 connected to the output end of the tilting drive motor 14 and a driven gear 152 connected to the tilting shaft 13. The driving gear 151 and the driven gear 152 mesh. After the tilting drive motor 14 is started, it drives the tilting shaft 13 to rotate relative to the bushing 12 through the driving gear 151 and the driven gear 152.

[0048] The tilting support 11 is connected to the tilting shaft 13. When the tilting shaft 13 rotates, it drives the single-sided protective canopy 16 to tilt as a whole between a horizontal protective position and a tilting clearance position. The so-called horizontal protective position refers to the position where the single-sided protective canopy 16 is roughly located above the long rail train and can form an electrostatic shielding protection for the space above the workers; the so-called tilting clearance position refers to the position where the single-sided protective canopy 16, after tilting at a certain angle relative to the horizontal protective position, makes way for the loading, unloading, hoisting, or other working space of the long rail. The single-sided protective canopy 16 is an integral structure, and during the tilting process, it rotates as a whole around the tilting shaft 13, without the need to disassemble the canopy into multiple small canopy panels that can be tilted separately, which helps to improve the consistency of the tilting action and the structural stability after repositioning.

[0049] The single-sided protective canopy 16 has a canopy steel frame 161 and an insulating protective plate 162 laid on the canopy steel frame 161. The canopy steel frame 161 can be formed by a combination of structural steel, rectangular tubes, or plates, and is used to support the insulating protective plate 162 and ensure that the protective canopy has sufficient rigidity. The outer periphery of the canopy steel frame 161 is provided with a side frame beam 163, which is arranged along the outer periphery of the single-sided protective canopy 16 to strengthen the circumferential strength of the canopy and provide support for the installation of the insulating protective plate 162.

[0050] The frame beam 163 is fixed to both ends of the horizontal rack 8 by the clamping member 164, so that the horizontal rack 8 can drive the entire protective canopy 16 on one side to move when it moves laterally.

[0051] In one alternative embodiment, a single-sided integral protective canopy 16 is provided on both sides of the long rail train in the width direction. The single-sided integral protective canopies 16 on both sides are arranged facing each other in the horizontal protection position and are close to each other at adjacent edges.

[0052] To improve the overall stability of the two-sided integrated protective canopy 16 after closure, a locking pin structure is provided at the adjacent frame beams 163 of the two-sided integrated protective canopy 16. The locking pin structure includes a first locking member provided on one side frame beam 163, a second locking member provided on the other side frame beam 163, and a locking pin that can pass through the first and second locking members. When both sides of the one-sided integrated protective canopy 16 are flipped to the horizontal protective position and closed facing each other, the first and second locking members are aligned with each other, and the locking pin passes through the first and second locking members to lock the adjacent edges of the two-sided integrated protective canopy 16 together.

[0053] By setting the above-mentioned locking pin structure, the two single-sided integral protective canopies 16 can form mutual constraints in the horizontal protection position, reducing the possibility of relative misalignment, opening or lifting between the two single-sided integral protective canopies 16 under vehicle vibration or external force, thereby improving the continuity of the electrostatic shielding protection area and the structural stability of the protective canopy in the closed state.

[0054] The insulating protective plate 162 is preferably an epoxy fiberglass cloth laminate. Epoxy fiberglass cloth laminate has good electrical insulation properties and mechanical strength, making it suitable for electrostatic shielding protection structures in the operating environment of electrified railway sections. An insulating pad is provided between the insulating protective plate 162 and the steel frame 161 of the canopy. The insulating pad is made of rubber pads, insulating sheets, or other insulating materials to reduce direct contact between the insulating protective plate 162 and the metal steel frame 161, and to reduce the adverse effects of local conductive connections or mechanical wear on the insulation performance.

[0055] The working process of this invention is as follows: When the long rail train is in a working state that requires protection, the lifting drive motor 20 drives the synchronous transmission shaft 19 to rotate, the synchronous transmission shaft 19 drives the two lifting drive gears 4 to rotate synchronously, and the lifting drive gears 4 drive the lifting guide column 2 to rise or fall to a predetermined height by meshing with the vertical rack 3.

[0056] Subsequently, the translation drive motor 9 drives the horizontal rack 8 to extend laterally along the slide rail 7 via the translation drive gear 10, moving the single-sided protective canopy 16 to a position suitable for forming a protective area. When the single-sided protective canopy 16 is in the horizontal protective position, its insulating protective plate 162 is located above the workers, used to form electrostatic shielding and insulation protection between the workers and the live areas of the contact wire.

[0057] When the long rail train needs to perform rail loading, unloading, or other operations requiring clearing of working space, the translation drive motor 9 first drives the horizontal rack 8 to move the tilting support 11 and the single-sided protective canopy 16 laterally to a predetermined position. Then, the tilting drive motor 14 drives the tilting shaft 13 to rotate via the gear transmission assembly 15, causing the single-sided protective canopy 16 to tilt from its horizontal protective position to a tilting clearance position. After the operation is completed, the tilting drive motor 14 reverses the direction of the tilting shaft 13, returning the single-sided protective canopy 16 to its horizontal protective position. The translation drive motor 9 then drives the horizontal rack 8 to retract, and the lifting drive motor 20 adjusts the lifting guide column 2 to the corresponding height according to the vehicle's operating or operational status.

[0058] Because the lifting structure uses a lifting drive gear 4 meshing with a vertical rack 3 to move the lifting guide column 2, the height adjustment of the protective canopy has a clear guiding path; the translation structure uses a baffle 6, a slide rail 7, and a horizontal rack 8 in cooperation, which can achieve guided lateral movement within a limited space; the tilting structure uses a bushing 12 in cooperation with a tilting shaft 13, and the tilting drive motor 14 drives the tilting shaft 13 to rotate through a gear transmission assembly 15, so that the single-sided protective canopy 16 can tilt as a whole around a stable axis. The above-mentioned lifting, translation, and tilting structures work together to enable the electrostatic shielding protection device to adapt to the multi-condition operation requirements of long rail train sets and improve the stability and reliability of the protective canopy's operation.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any equivalent substitutions or modifications made to the shape, quantity, installation direction, transmission method, or connection method of the components within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
