Description

Technical Field

[0001] The present application relates to the field of rail vehicles, and in particular, to an auxiliary device for locking a skirt plate of a rail vehicle. Background Art

[0002] During the production and commissioning phase of high-speed EMUs, the installation and locking of the undercarriage equipment compartment skirt is a key step in ensuring the safe operation of the train. To ensure the smooth progress of this process, the existing technical solution adopts the following operation scheme:

[0003] Two-person collaboration: When locking the skirt, two people work together. One employee is responsible for closing the skirt with force to ensure that the gap between the skirt and the car body is as small as possible. The other employee uses the four-corner key to rotate the skirt lock 90 degrees to lock it. This two-person collaboration can improve the accuracy and efficiency of locking.

[0004] Auxiliary measures during locking: During the locking process, the employee responsible for pushing the skirt will push the skirt hard to further reduce the gap between the skirt and the vehicle body. This will help another employee to lock the skirt lock more easily and reduce the resistance and difficulty during locking.

[0005] Confirmation and adjustment after locking: When the skirt lock is rotated 90 degrees and locked in place, the employee responsible for using the four-corner key will press the skirt lock cylinder toward the inside of the vehicle body to make the skirt lock automatically rebound because the skirt lock has a rebound function. This step ensures that the plane between the skirt lock and the skirt is flush, improving the stability and reliability of the lock.

[0006] This solution still relies heavily on manual operation, including two people working together, pushing the skirt plate hard, rotating the four-corner key, etc. This highly manual method is easily affected by human factors, such as unskilled operation and lack of concentration, which may lead to problems such as inadequate locking or damage to the lock core.

[0007] This solution involves multiple operation steps and collaborative work, which requires employees to have certain operation skills and experience. For new employees or employees who are not familiar with the operation, there may be risks of difficulty in operation or misoperation.

[0008] The need for two people to work together and push the skirts hard increases the safety risks during operation. At the same time, if the locking is not in place or there are other problems, the skirts may fall off when the train is running at high speed, causing serious safety accidents. In addition, the complexity of the operation and the dependence on manpower may also affect the efficiency of the operation. Summary of the invention

[0068] In a specific embodiment, the auxiliary device for locking the rail vehicle skirt provided by the present application includes a handle body 1, a skirt pressing block 2, a bracket 3 and a vehicle body auxiliary fixing assembly 4. Among them, the handle body 1 is used to provide the operator with a gripping position and a transmission function of the operating force. It is preferably designed to be ergonomic and covered with an anti-slip material on the surface to ensure that the user holds it stably during operation. The length and diameter of the handle are carefully calculated to accommodate the hand size of most operators. The handle body 1 is preferably set to a cylindrical or rectangular structure, which can be set as needed.

[0069] The skirt panel pressing block 2 is located at the bottom of the handle body 1, and is used to press-fit the rail vehicle skirt panel.

[0070] The bracket 3 is located at one end of the handle body 1 along the length direction, and is arranged horizontally along the handle body 1. The handle body 1 is hinged to the bracket 3 and rotates around the bracket 3. The bracket 3 provides a rotation axis for the handle body 1. During the rotation of the handle body 1 around the bracket 3, the skirt plate pressing block 2 is driven to move towards the skirt plate and press the skirt plate.

[0071] In this specific embodiment, the bracket 3 includes two vertical brackets 31 arranged opposite to each other and a transverse bracket 32. The transverse bracket 32 ​​is connected between the two vertical brackets 31, and is rotatably connected to the handle body 1 and provides a rotation axis for the handle body 1. Any vertical bracket 31 is fixed to the vehicle body auxiliary fixing assembly 4. A vertical bracket 31 is respectively provided at both ends of the transverse bracket 32 ​​in the length direction. The vertical bracket 31 and the transverse bracket 32 ​​are preferably arranged in an integrated manner. The handle body 1 is rotatably connected to the transverse bracket 32. The transverse bracket 32 ​​provides a rotation axis for the handle body 1. The handle body 1 rotates around the transverse bracket 32, such as moving closer to or away from one side of the rail vehicle skirt board, and the skirt board is pressed.

[0072] Specifically, a rotating connection part 321 is provided in the middle of the transverse bracket 32; the end top wall 4331 of the handle body 1 is provided with a mounting block 12 and a first mounting groove 11 extending in the transverse direction, the mounting block 12 is detachably fixedly connected to the handle body 1, and the bottom wall of the mounting block 12 is provided with a second mounting groove 121 extending in the transverse direction, the first mounting groove 11 and the second mounting groove 121 are connected to form a rotating limit cavity, and the rotating connection part 321 is rotatably connected in the rotating limit cavity.

[0073] The transverse bracket 32 ​​is preferably configured as a rod-shaped structure, and the rotating connecting portion 321 is also configured as a rod-shaped structure, and the diameter of the rotating connecting portion 321 is larger than the diameter of the transverse bracket 32, so as to facilitate cooperation with the first mounting groove 11; the top wall 4331 at one end of the handle body 1 in the length direction is provided with a first mounting groove 11 for cooperation with the rotating connecting portion 321; the mounting block 12 is located on the end wall top wall 4331 of the handle body 1, and the bottom wall where the mounting block 12 cooperates with the handle body 1 is provided with a second mounting groove 121, and the second mounting groove 12 1 extends laterally along the mounting block 12, the second mounting groove 121 and the first mounting groove 11 are connected to form a rotation limiting cavity, the second mounting groove 121 and the first mounting groove 11 are preferably respectively set as semicircular grooves, and the rotation limiting cavity forms a cylindrical cavity structure and contacts the rotation connection part 321; the mounting block 12 fixes the device to the bracket 3 to ensure that the vehicle body auxiliary fixing component 4 will not shift up and down, and the mounting block 12 applies the force of the handle body 1 to the vehicle body auxiliary fixing component 4 to ensure that the handle body 1 can be fixed on the bracket 3.

[0074] Specifically, the mounting block 12 is a rectangular structure and has a mounting hole for the mounting block 12. The mounting hole for the mounting block 12 is a through hole. After the fastening bolt passes through, it realizes a mechanical connection with the handle body 1. An arc surface is provided on the outer wall of the mounting block 12, which is convenient for the operator to grasp during assembly.

[0075] In another embodiment, the vehicle body auxiliary fixing assembly 4 is used to detachably fix the handle body 1 to the rail vehicle body, so that the handle body 1 can drive the skirt panel pressing block 2 to press the rail vehicle skirt panel, ensuring that the device will not fall off during operation.

[0076] The vehicle body auxiliary fixing component 4 is preferably a suction cup 42 structure, which includes a suction cover 41, a suction cup 42 and a suction auxiliary mechanism 43; the bottom of the suction cover 41 is provided with an open first suction cavity 411, and the top wall 4331 of the suction cover 41 is provided with a suction cover switch hole 412 connected to the first suction cavity 411; the bracket 3 is fixed on the suction cover 41;

[0077] The bottom of the suction cup 42 has an open second suction cavity 421, the suction cup 42 is located in the first suction cavity 411, and the top wall 4331 of the suction cup 42 is provided with a suction cup switch protrusion 422, which penetrates the suction cover switch hole 412 and extends upward;

[0078] The adsorption auxiliary mechanism 43 is hinged at one end to the handle body 1 and connected to the suction cup switch protrusion 422 at the other end. When the handle body 1 rotates around the bracket 3, the adsorption auxiliary mechanism 43 drives the suction cup switch protrusion 422 to drive the suction cup 42 to move up and down, squeezing or releasing the gas in the first adsorption chamber 411 and the second adsorption chamber 421 to vacuum the vehicle body.

[0079] Among them, the suction cup switch protrusion 422 is preferably set as a suction cup 42 switch protrusion, and the suction cup 42 switch protrusion is provided with a suction cup switch action hole 4221; the suction cover switch hole 412 is preferably set as a circular hole, and the two vertical brackets 31 are respectively fixed on both sides of the diameter direction of the suction cover 41, and the top wall 4331 of the suction cover 41 is provided with a suction cover switch hole 412, and the suction cup switch protrusion 422 extends upward through the suction cover switch hole 412. When the suction cup switch protrusion 422 moves upward, it drives the top wall 4331 of the suction cup 42 to move upward, and the space between the first adsorption chamber 411 and the suction cup 42 is squeezed, and the gas is discharged through the suction cover switch hole 412. The first adsorption chamber 411 of the suction cover 41 forms a negative pressure due to the gas discharge, and the suction cover 41 forms adsorption, and at the same time, a force is applied to the suction cup 42 to discharge the gas in the second adsorption chamber 421 of the suction cup 42 to form a negative pressure, thereby pressing the suction cup 42 onto the rail vehicle body, thereby achieving fixation between the auxiliary device and the body. The suction cover 41 is used to protect the suction cup 42, prevent dust and debris from contaminating, and ensure the adhesion performance of the suction cup 42. There is a cavity and a sealing function inside. When the vacuum is drawn, the suction cup 42 can be opened and closed to facilitate the operator to use the suction cup 42. The suction cup 42 absorbs the auxiliary device on the vehicle body through the negative pressure principle to ensure that the auxiliary device does not fall off during operation. The suction cup 42 is usually made of a soft rubber material with a certain elasticity and adhesion. When the operator operates the suction cup pressure rod 432, the air inside the suction cup 42 is discharged, forming a negative pressure, so that the suction cup 42 is tightly adsorbed on the vehicle body.

[0080] In a specific embodiment, the adsorption auxiliary mechanism 43 includes a suction cup switch tension rod 431 and a suction cup pressure rod 432; the suction cup switch tension rod 431 is inserted into the suction cup switch action hole 4221 to drive the suction cup 42 to move up and down; one end of the suction cup pressure rod 432 is hinged to the handle body 1, and the other end is hinged to the suction cup switch tension rod 431; during the rotation of the handle body 1 around the bracket 3, the suction cup pressure rod 432 is driven to drive the suction cup 42 to move up and down through the suction cup switch protrusion 422.

[0081] The suction cup switch tension rod 431 and the suction cup switch action hole 4221 are preferably clearance-matched. Driven by the rotation of the handle body 1, the suction cup switch tension rod 431 drives the suction cup pressure rod 432 to drive the suction cup switch action hole 4221 and the suction cup switch protrusion 422 to move up and down.

[0082] It can be understood that the suction cup pressure rod 432 is used to operate the suction cup 42 to adsorb and release the suction cup 42; in other embodiments, the suction cup pressure rod 432 is generally a retractable structure, and the adsorption and release of the suction cup 42 are controlled by push-pull operations; during adsorption, the operator pulls the pressure rod outward to discharge the air inside the suction cup 42 to form a negative pressure; during release, the operator pushes the pressure rod inward to allow the air inside the suction cup 42 to enter, thereby destroying the negative pressure state.

[0083] In another embodiment, the adsorption auxiliary mechanism 43 further includes a pressure rod fixing frame 433, which is detachably fixed to the handle body 1; the pressure rod fixing frame 433 includes:

[0084] A top wall 4331 and two side walls 4332 arranged opposite to each other on both sides of the top wall 4331, the top wall 4331 is provided with a pressure rod fixing frame mounting hole 43311 for fixing to the handle body 1;

[0085] The pressure rod support rod 4333 is located between the two side walls 4332, and both ends are fixed to the corresponding side walls 4332 respectively; the suction cup pressure rod 432 has a pressure rod mounting hole 4321, and the pressure rod mounting hole 4321 is sleeved on the pressure rod support rod 4333 with a clearance fit, and the suction cup pressure rod 432 is rotatably connected to the pressure rod support rod 4333 through the pressure rod mounting hole 4321.

[0086] The pressure rod fixing frame 433 is used to support and fix the suction cup pressure rod 432, ensuring that the suction cup pressure rod 432 maintains a stable position and direction during operation. The pressure rod fixing frame 433 usually adopts a sturdy structural design, such as a metal frame or a plastic bracket 3. The pressure rod fixing frame 433 adopts a U-shaped structure, and the U-shaped structure is detachably fixedly connected to the handle body 1, and the connection with the suction cup pressure rod 432 at the bottom ensures that the suction cup pressure rod 432 will not shake or deviate from the predetermined trajectory during operation. The suction cup pressure rod 432 is a cylindrical structure with a cavity inside to reduce the weight of the device.

[0087] In another embodiment, the suction cup switch tension rod 431 includes:

[0088] An action hole transition portion 4311 and axial limiting portions 4312 axially located at two ends of the action hole transition portion 4311;

[0089] And / or, the diameter of the axial limiting portion 4312 is greater than the diameter of the active hole transition portion 4311 , thereby limiting the axial movement of the active hole transition portion 4311 .

[0090] The action hole adapter 4311 is set as a cylindrical structure, which is connected to the suction cup switch action hole 4221, and drives the suction cup 42 to move up and down under the drive of the suction cup pressure rod 432, so as to adsorb and release the suction cup 42. Preferably, the suction cup pressure rod 432 has a pressure rod cavity, and the pressure rod cavity is connected to the action hole adapter 4311, so that the suction cup pressure rod 432 moves in the pressure rod cavity.

[0091] Optionally, the handle body 1 is a V-shaped structure, which includes a first handle portion 13 and a second handle portion 14, and the tail end of the first handle portion 13 has a handle sheath 5; the skirt plate pressing block 2 is located at the head end of the second handle portion 14 close to the first handle portion 13, and the bracket 3 is located at the tail end of the second handle portion 14. In other embodiments, the handle body 1 can be set as an L-shaped structure to achieve force transmission.

[0092] Two mounting holes for mounting the mounting block 12 are respectively provided at the ends of the handle body 1, and bolts are used for connection to prevent the mounting block 12 from falling off. The mounting block 12 is placed on the handle body 1, aligned with the mounting holes of the mounting block 12, and the mounting block 12 and the handle body 1 are connected by bolts, and the mounting block 12 and the handle body 1 are locked to prevent the mounting block 12 from moving.

[0093] In one embodiment, the skirt plate pressing block 2 comprises:

[0094] The pressing block body 21 has a pressing block mounting hole 211, and the pressing block body 21 is fixed to the handle body 1 through the pressing block mounting hole 211 and a countersunk hexagon socket head bolt;

[0095] The bottom of the pressing block body 21 is provided with a pressing block skirt contact surface 212 which matches the shape of the railway vehicle skirt.

[0096] The skirt plate pressing block 2 transmits the downward force generated by the handle body 1 to the skirt plate through the skirt plate pressing block 2, so that the skirt plate is in full contact with the vehicle body and the gap between the vehicle bodies is reduced; the pressing block mounting hole 211 is an internal countersunk through hole, which is used for the countersunk hexagon socket bolt to pass through the pressing block mounting hole 211 to achieve mechanical connection with the handle body 1. The pressing block skirt plate contact surface 212 of the skirt plate pressing block 2 is consistent with the shape of the skirt plate surface, so that the skirt plate pressing block 2 is in full contact with the skirt plate, the gap with the skirt plate surface is reduced, and the pressing force is fully transmitted to the skirt plate.

[0097] The second handle portion 14 of the handle body 1 is also provided with four mounting holes for mounting the skirt plate pressing block 2, which are connected by bolts to prevent the skirt plate pressing block 2 from falling off. The skirt plate pressing block 2 is placed on the handle body 1, aligned with the pressing block mounting holes 211 of the skirt plate pressing block 2, and the skirt plate pressing block 2 and the handle body 1 are connected and locked by bolts to prevent the skirt plate pressing block 2 from moving.

[0098] The outer wall of the handle sheath 5 is cylindrical, and the handle sheath 5 has a handle body mounting hole 51 inside, which is a square hole for sleeve connection with the first handle 13. The handle sheath 5 is used to protect the handle body 1 and other connecting parts, prevent wear and damage, and extend the service life of the device. The sheath is usually made of wear-resistant and anti-aging materials, such as rubber or plastic. It is tightly wrapped around the handle body 1 and other connecting parts to provide additional protection and reduce the impact of external factors on the device.

[0099] In a specific implementation, the specific operation process of locking the skirt plate of a railway vehicle by the auxiliary device for locking the skirt plate includes:

[0100] ① Check that all parts of the auxiliary device for locking the skirt plate of rail vehicles are intact and in good appearance.

[0101] ② The suction cup 42 in the auxiliary device for locking the rail vehicle skirt is brought close to the vehicle body, and the operator presses down hard, so that the suction cup 42 is adsorbed on the vehicle body.

[0102] ③ After the skirt board is manually lifted up, the skirt board is pressed hard to make the skirt board lock automatically close, and the auxiliary device for locking the skirt board of the rail vehicle is operated to make the skirt board contact surface 212 of the pressing block contact with the skirt board surface.

[0103] ④ The employee operates the handle body 1 to move downward, and under the action of the lever force, the contact surface 212 of the pressure block skirt plate generates a contact force with the skirt plate surface, so that the gap between the skirt plate and the vehicle body becomes smaller.

[0104] ⑤ The employee uses the four-corner key to rotate the skirt lock clockwise to lock the skirt lock in place. After releasing the four-corner lock, the four-corner lock tongue automatically pops out to quickly lock the skirt lock.

[0105] The specific operation process of opening the skirt plate by the auxiliary device for locking the skirt plate of a railway vehicle includes:

[0106] ① Check that all parts of the auxiliary device for locking the skirt plate of rail vehicles are intact and in good appearance.

[0107] ② The suction cup 42 in the auxiliary device for locking the rail vehicle skirt is brought close to the vehicle body, and the operator presses down hard, so that the suction cup 42 is adsorbed on the vehicle body.

[0108] ③ The employee operates the handle body 1 to move downward, and under the action of the lever force, the contact surface 212 of the pressure block skirt plate generates a contact force with the skirt plate surface, so that the gap between the skirt plate and the vehicle body becomes smaller.

[0109] ⑤ The employee uses the four-corner key to rotate the skirt board lock counterclockwise and turn the skirt board lock to the open position, and then the skirt board lock can be easily opened. After releasing the four-corner lock, the four-corner lock tongue will automatically pop out to realize the quick opening of the skirt board lock.

[0110] It is understandable that in conventional technology, the locking work of the existing skirt lock requires two workers to cooperate with each other, which not only requires tacit cooperation between the workers, but also may cause errors in communication or operation, affecting work efficiency. After adopting the auxiliary device for locking the skirt of rail vehicles, only one worker is needed to complete the entire locking work. This not only simplifies the operation process, but also avoids the errors that may be caused by the cooperation of multiple people, thereby significantly improving the working efficiency of the portable skirt lock.

[0111] Secondly, the locking device designed for high-speed EMU skirt locks fully considers the workers' operating habits and usage experience. Its humanized design allows workers to easily get started and reduces learning costs. At the same time, due to the automation and modularity of the device, workers no longer need to use too much force or perform complex operations, thereby reducing labor intensity.

[0112] Thirdly, without a dedicated locking device, the skirt lock may have quality problems such as deformation of the lock tongue during the locking process, resulting in locking failure. This not only affects the normal operation of the EMU, but may also cause safety hazards. The auxiliary device for locking the skirt of rail vehicles ensures the stability of the lock tongue during the locking process through its precise mechanical structure and stable performance, effectively reducing quality problems such as deformation of the lock tongue, thereby improving the locking operation quality of the skirt lock of high-speed EMUs.

[0113] Finally, the traditional skirt lock locking method often relies on the experience and skills of workers, lacking support for standardization and automation. The application of auxiliary devices for rail vehicle skirt locking not only changes this situation, but also promotes innovation in production methods. Through the introduction of the device, the production process is more standardized and automated, thereby improving production efficiency. In addition, the detachable and modular design of the device also allows multiple skirt locks to be operated simultaneously, further improving production efficiency.

[0114] In summary, the application of the auxiliary device for locking the skirt of rail vehicles not only improves work efficiency and operation quality, but also reduces the labor intensity of workers and improves production efficiency. The auxiliary device for locking the skirt of rail vehicles is not only suitable for high-speed EMUs, but can also be adjusted as needed and applied to other types of trains or vehicles. Its modularity, automatic adjustment and quick disassembly characteristics make the device have broad application prospects in train maintenance and overhaul.
