Description

Technical Field

[0001] The present invention relates to the technical field of rail transit test equipment, and in particular to a performance test bench for a rack bogie and a method for using the same. Background Art

[0002] A rack train is a new type of rail vehicle used on mountain railways, earning it the nickname "the climbing expert" of the railway family. Its track design is quite unique: in addition to the conventional two rails, a third rail with teeth and grooves, known as the rack, is laid in the middle of the track. Correspondingly, a gear mechanism is installed on the underside of the train, precisely matching the rack. When the train climbs, the gears in the running gear mesh tightly with the rack, generating a force that propels the train forward. This ingenious design allows it to easily navigate steep slopes.

[0003] Due to their special operating environment and structural design, it is of great significance to conduct structural response analysis on rack-and-rail trains. When operating in complex mountainous areas, they not only have to bear the loads of conventional wheel-rail trains, but also have to cope with the dynamic forces generated by the meshing of the rack and rail, while facing additional challenges brought by steep slopes, curves and other road conditions. In addition, harsh environments such as high altitudes and large temperature differences can also affect the structural performance of the train. Through structural response analysis, it is possible to conduct in-depth research on the vibration, stress distribution, fatigue characteristics, etc. of the train under various operating conditions, thereby optimizing the train structural design, ensuring the strength and stability of key components, improving the safety and reliability of train operation, extending the service life, and providing a scientific basis for maintenance and inspection to ensure the efficient and safe operation of rack-and-rail trains.

[0004] Existing rack test equipment is mostly designed for a single working condition and lacks the ability to conduct comprehensive tests on dynamic slopes or the entire rack bogie, making the data obtained from the tests insufficient for reference. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects in the prior art that the rack test devices are mostly designed for a single working condition, lack the ability to carry out comprehensive tests on dynamic slopes or on the rack bogie as a whole, and make the data obtained from the tests insufficient for reference, and to provide a performance test bench for a rack bogie and a method for using the same.

[0006] In a first aspect, the present invention provides a rack bogie gear rack meshing performance test bench, comprising: Test bench rack; An adjustment platform, the adjustment platform is arranged above the test bench frame, the rear side of the adjustment platform is hinged to the test bench frame, the adjustment platform can be rotated along the hinge point and locked in position, and the adjustment platform is provided with an active member, and the active member can rotate; The bogie is arranged on the top surface of the adjustment platform. The bogie includes a frame, a rack wheel and a plurality of running wheels. The rack wheel and the running wheels can rotate. The rotation of the active member drives the rack wheel to rotate. The rotation of the adjustment platform drives the bogie to tilt.

[0007] During the test, the side where the hinge point is located is the rear side of the adjustment table.

[0008] One side of the adjustment table is hinged to the test bench frame. The adjustment table can be rotated and locked along the hinge point, thereby simulating the slope of different lines as closely as possible, involving different operating conditions. It can conduct structural response tests on dynamic slopes, which helps to improve the accuracy of test results. The bogie is installed, which includes rack wheels and running wheels. The rack wheels and running wheels can rotate, which is as close as possible to the actual operation of the rack railway, which helps to improve the accuracy of the test results and enhance the reference value of the test results.

[0009] Preferably, a telescopic device is provided between the adjustment platform and the test platform frame, and the extension or contraction of the telescopic device can drive the adjustment platform to rotate along the hinge point.

[0010] A telescopic device is provided, and the extension or contraction of the telescopic device drives the adjustment table to rotate along the hinge point, which is convenient for adjustment.

[0011] Preferably, two sides of the telescopic device are hinged to the adjustment platform and the test bench frame respectively.

[0012] The two sides of the telescopic device are hinged to the adjustment table and the test bench frame respectively, and will not affect the rotation of the adjustment table around the hinge point. Preferably, it further comprises a stopper, which is arranged on the rear side of the adjustment platform and is connected to the rear running wheel of the bogie.

[0013] During the actual test process, the height of the front side of the adjustment platform is higher than that of the rear side, so a stopper is set to prevent the bogie from sliding down as much as possible.

[0014] Preferably, a pressure sensor is provided between the stopper and the running wheel.

[0015] A pressure sensor is set between the stopper and the running wheel to measure the pressure applied by the running wheel on the stopper. The rotation speed of the rack wheel is adjusted according to the pressure measured by the pressure sensor. This can be as close as possible to the actual working environment of the rack railway, thereby ensuring the accuracy of the test as much as possible.

[0016] Preferably, the active member is a rack chain and a chain gear, the chain gear rotates to drive the rack chain to rotate, the rack chain is engaged with the rack wheel, and the rack chain rotates to drive the rack wheel to rotate.

[0017] The active parts are the rack chain and chain gear, which ensure that the contact form with the rack wheel is as close as possible to the actual operation of the rack train, which is conducive to improving the accuracy of the test results.

[0018] Preferably, the adjustment platform is further provided with a chain support plate, and the chain support plate is used to support the rack chain and the rack wheel.

[0019] Setting up chain support plates helps to improve the stability of the structure.

[0020] Preferably, the adjustment platform is also provided with an active support wheel and a passive support wheel, and the active support wheel and the passive support wheel are both connected to the walking wheel. The front side and the rear side of any walking wheel are respectively provided with the active support wheel and the passive support wheel, and the rotation of the active support wheel drives the rotation of the walking wheel, and the rotation of the walking wheel drives the rotation of the passive support wheel.

[0021] By setting support wheels, and providing active support wheels and passive support wheels on the front and rear sides of any support wheel, any support wheel can be rotated, simulating the situation of the rack train in the actual use scenario as much as possible, which is conducive to improving the accuracy of the test results.

[0022] Preferably, the top surface of the adjustment platform is further provided with at least two steel rails, the length direction of the steel rails is parallel to the traveling direction of the bogie, and the positions of the steel rails are adapted to the positions of the traveling wheels of the bogie.

[0023] Steel rails are provided, and the positions of the steel rails are adapted to the positions of the running wheels, so as to facilitate the bogie to drive in or out of the adjustment platform.

[0024] In a second aspect, the present invention provides a method for using a performance test bench for a rack bogie, using the rack bogie gear and rack meshing performance test bench as described above, comprising the following steps: S1. Place the bogie on the top surface of the adjustment platform, connect the rack wheel and the active component, rotate the adjustment platform along the hinge point to the predetermined position and fix it; S2. Rotate the active member at a uniform speed, so that the active member drives the rack wheel to rotate at a uniform speed; accelerate the rotation speed of the rack wheel until the gravity component of the bogie in the direction parallel to the top surface of the adjustment platform is balanced; S3. Perform a dynamic response test of the rack railway train. After the test is completed, return the adjustment platform to its original position, and drive the running wheels to move and detach from the adjustment platform, thereby completing the dynamic response test of the rack railway train under the simulated slope.

[0025] By rotating the active element at a constant speed, the rack wheel's rotational frequency remains very constant, facilitating precise extraction of the rack wheel's natural vibration characteristics and minimizing speed fluctuations that could interfere with spectral analysis. Furthermore, if the angle between the adjustment table and the test stand frame needs to be changed while maintaining the constant rack wheel's rotational frequency, speed interference can be minimized, effectively defining the design critical load. By accelerating the active element, the rack wheel's rotational frequency increases, simulating the climbing conditions of a rack bogie. The meshing of the rack wheel with the rack generates traction, reducing the bogie's force component in the downhill direction of the track to zero. In dynamic response testing of rack trains, the active element can be rotated at a constant speed first and then accelerated, or accelerated first and then rotated at a constant speed. The bogie's gravity component parallel to the top surface of the adjustment table is balanced, meaning the rear running wheels no longer transmit pressure to components behind them.

[0026] This method can simulate sudden changes in slope during the operation of a rack train and eliminate the influence of speed to extract the inherent vibration characteristics of the rack wheels, making it applicable to a variety of operating conditions. Furthermore, direct testing on the bogies more closely reflects the actual use of rack trains, which helps improve the accuracy of the test results.

[0027] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a rack-and-steel bogie gear-cog meshing performance test bench, comprising a test bench frame, an adjustment platform and a bogie, wherein one side of the adjustment platform is hinged to the test bench frame, and the adjustment platform can be rotated and locked along the hinge point, so as to simulate the slopes of different lines as much as possible, involving different working conditions, and capable of conducting structural response tests on dynamic slopes, which is conducive to improving the accuracy of the test results. A bogie is provided, and the bogie comprises rack wheels and running wheels, and the rack wheels and running wheels can rotate, as close as possible to the actual operation of the rack railway, which is conducive to improving the accuracy of the test results, thereby improving the reference value of the test results. The present application overcomes the defects of the rack test devices existing in the prior art, which are mostly designed for a single working condition and lack the ability to conduct comprehensive tests on dynamic slopes or the rack-and-steel bogie as a whole, resulting in insufficient reference value of the data obtained from the test.

[0028] 2. The present invention provides a method for using a performance test bench for a rack bogie. The bogie is first placed on the top surface of an adjustment table, and the adjustment table is rotated along the hinge point. The rack wheels are then rotated at a constant speed and at an accelerated speed, respectively, and finally a dynamic response study is conducted. This method can simulate the climbing conditions of a rack train during operation and can also eliminate the influence of speed to extract the inherent vibration characteristics of the rack wheels. It is applicable to various working conditions. Directly setting up the bogie for testing is closer to the actual use of the rack train, which helps to improve the accuracy and reference value of the test results.

DETAILED DESCRIPTION

[0031] The present invention will be further described in detail below with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments, as all technologies implemented based on the present invention fall within the scope of the present invention.

[0032] Unless otherwise specified, in the description of the specific embodiments of the present invention, the terms indicating the orientation or positional relationship, such as "upper", "lower", "left", "right", "center", "inside", and "outside", are based on the expressions of the orientation or positional relationship shown in the accompanying drawings, or are the orientation or positional relationship in which the invented product / device / apparatus is placed when it is conventionally used. These terms of orientation or positional relationship are merely for the purpose of facilitating the description of the scheme of the present invention or simplifying the description of the specific embodiments to facilitate the rapid understanding of the scheme by technicians, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship, and therefore should not be understood as limiting the present invention.

[0033] In addition, if the terms "horizontal", "vertical", "overhanging", "parallel" and the like appear, it does not mean that the corresponding devices / components / elements are required to be absolutely horizontal or vertical or overhanging or parallel, but may be slightly tilted or have deviations.

As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its role in the solution of the present invention.

[0034] In addition, the expressions “first”, “second”, “third”, etc. in the terms are merely used to distinguish the description of the same or similar components, and should not be understood as emphasizing or implying the relative importance of specific components.

[0035] In addition, in the description of the embodiments of the present invention, "several," "plurality," and "a number" represent at least two. It can also be any number such as two, three, four, five, six, seven, eight, nine, or even more than nine.

[0036] Furthermore, in the description of the technical solution of the present invention, unless otherwise expressly specified, defined, or limited, the terms "disposed," "installed," "connected," "connected," "provided with," "laid," and "arranged" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections. They may be welded, riveted, bolted, threaded, or other commonly used connection methods in the art. Such connections may be mechanical, electrical, or communicative; they may be direct, indirect via an intermediate medium, or internally connected between two components.

[0037] Example 1 like Figures 1 to 3 As shown, a rack bogie gear rack meshing performance test bench comprises: Test bench frame 1; An adjustment platform is provided above the test bench frame 1, the rear side of the adjustment platform is hinged to the test bench frame 1, the adjustment platform can be rotated along the hinge point 102 and locked in position, and the adjustment platform is provided with an active member that can rotate; The bogie 4 is arranged on the top surface of the adjustment platform. The bogie 4 includes a frame, a rack wheel 401 and a plurality of running wheels 402. The rack wheel 401 and the running wheels 402 can rotate. The rotation of the active member drives the rack wheel 401 to rotate, and the rotation of the adjustment platform drives the bogie 4 to tilt.

[0038] In this embodiment, the bogie 4 includes four running wheels 402 and a rack wheel 401. The rack wheel 401 is arranged between the two running wheels 402 on the front side. Figure 1 and Figure 2 As shown, the position arrangement of the rack wheel 401 as close as possible to the rack train is conducive to ensuring the accuracy of the test results.

[0039] During the test, the side where the hinge point 102 is located is the rear side of the adjustment table.

[0040] One side of the adjustment platform is hinged to the test bench frame 1. The adjustment platform can be rotated and locked along the hinge point 102, thereby closely simulating the different slopes of the rack railway in actual operation. This covers different working conditions and allows for structural response testing under dynamic slopes, which helps improve the accuracy of test results. A bogie 4 is provided, which includes a rack wheel 401 and a running wheel 402. The rack wheels 401 and 402 are able to rotate, closely simulating the actual operation of the rack railway, which helps improve the accuracy of test results.

[0041] Furthermore, the top surface of the test bench frame 1 is provided with several support rods 104, each of which is connected to the top surface of the test bench frame 1 and the bottom surface of the adjustment platform. In this embodiment, at least one set of support rods 104 is included, with one set of support rods 104 comprising a first support rod 104 positioned in front of the front wheels 402 and a second support rod 104 positioned behind the rear wheels 402. The adjustment platform is hinged on one side to the second support rod 104, while the other side can be placed on top of the first support rod 104. The distance between the bottom surface of the adjustment platform and the first support rod 104 is adjustable.

[0042] Furthermore, a telescopic device is provided between the top surface of the test bench frame 1 and the bottom surface of the adjustment platform. In this embodiment, the telescopic device is a hydraulic telescopic rod 101, and both ends of the hydraulic telescopic rod 101 are hinged to the test bench frame 1 and the adjustment platform. The extension or contraction of the hydraulic telescopic rod 101 drives the adjustment platform to rotate along the hinge point 102 of the second support rod 104, thereby adjusting the angle between the adjustment platform and the test bench frame 1, and then driving the bogie 4 to tilt, which can be closer to the actual working environment of the rack railway and is conducive to improving the accuracy of the rack test results. In other embodiments, the hydraulic telescopic rod 101 can be replaced with a pneumatic telescopic sleeve, a ball screw telescopic system or a scissors-type lifting mechanism, which is not limited in this application.

[0043] Furthermore, a stopper 303 is provided on the rear side of the adjustment platform and connected to the rear running wheel 402 of the bogie 4. The tilted adjustment platform causes a gravitational force component on the bogie 4 in a direction parallel to the adjustment platform. If the rack wheel 401 of the bogie 4 is not rotating fast enough, it cannot balance the gravitational force in this direction. Therefore, the stopper 303 is provided to minimize displacement of the bogie 4, which could affect the test. Furthermore, a pressure sensor is provided between the stopper 303 and the running wheel 402. The pressure sensor can be used to measure the pressure applied by the running wheel 402 to the stopper 303. When the pressure applied by the running wheel 402 to the stopper 303 is 0, it can be considered that the bogie 4 has been simulating the working condition of a sudden change in slope during the climbing process of the rack train. In actual use, the pressure sensor can also be connected to a display module or an alarm module, and the display module displays the pressure received by the pressure sensor; or when the pressure received by the pressure sensor is 0, the alarm module emits a sound to remind. The specific connection structure can refer to the connection system of the existing pressure sensor, and this application does not impose any restrictions.

[0044] Furthermore, the active member is a rack chain 201 and a sprocket 202. The rotation of the sprocket 202 drives the rack chain 201 to rotate. The rack chain 201 is engaged with the rack wheel 401. The rotation of the rack chain 201 drives the rack wheel 401 to rotate. The rack chain 201 and the sprocket 202 are provided so as to be as close as possible to the use scenario of the rack train, which is conducive to improving the accuracy of the test results. In this embodiment, the rack chain 201 is driven by a sprocket motor 204, and the sprocket motor 204 is also connected to a gearbox 203, which can control the rotation speed of the rack chain 201, thereby simulating different working conditions during the operation of the rack train. The adjustment platform is also provided with a chain support plate 103, which is used to support the rack chain 201 and the rack wheel 401.

[0045] Furthermore, the adjustment platform is further provided with an active support wheel 3011 and a passive support wheel 3012, and the active support wheel 3011 and the passive support wheel 3012 are both connected to the running wheel 402. The front and rear sides of any running wheel 402 are respectively provided with the active support wheel 3011 and the passive support wheel 3012. The active support wheel 3011 rotates to drive the running wheel 402 to rotate, and the running wheel 402 rotates to drive the passive support wheel 3012 to rotate. In this embodiment, an active support wheel 3011 and a passive support wheel 3012 are respectively provided on the front and rear sides of a running wheel, which can not only drive the running wheel 402 to rotate, but also support the running wheel 402. The active support wheel 3011 and the support wheel motor 302 are connected by a belt, and the support wheel motor 302 drives the active support wheel 3011 to rotate. The support wheel motor 302 is arranged below the active support wheel 3011 and located at the lower part of the top surface of the adjustment platform, and is used to simulate the adhesion operating condition of the rack bogie (non-rack meshing operating condition).

[0046] Furthermore, at least two rails 304 are provided on the top surface of the adjustment platform. The length direction of the rails 304 is parallel to the traveling direction of the bogie 4. The positions of the rails 304 are adapted to the positions of the traveling wheels 402 of the bogie 4. Figure 1 and Figure 2 As shown, the rail 304 is broken into multiple sections below the running wheel 402, leaving space for the active support wheel 3011 and the passive support wheel 3012. The rail 304 is used to support the bogie 4 to enter or exit the adjustment platform.

[0047] In this embodiment, Figure 3 As shown, the rack chain 201 includes teeth 2011, chain links 2012 and rollers 2013. The teeth 2011 and chain links 2012 are arranged alternately, and the positions of the rollers 2013 and chain links 2012 correspond to each other. The spacing between two adjacent teeth 2011 matches the tooth pitch of the rack wheel 401, which facilitates the engagement of the rack wheel 401 and the rack chain 201.

[0048] Example 2 like Figure 4 As shown, a method for using a performance test bench for a rack bogie, using a rack bogie gear and rack meshing performance test bench as described in Example 1, includes the following steps: S1, the bogie 4 drives along the rail 304 onto the top surface of the adjustment platform, engages the rack wheel 401 and the rack chain 201, extends the hydraulic telescopic rod 101, rotates the adjustment platform along the hinge point 102 to the predetermined position and fixes it; S2, the sprocket motor 204 is started, driving the chain gear 203 to rotate at a constant speed, and the chain gear 203 rotates to drive the rack wheel 401 to rotate at a constant speed. The rotation direction of the rack wheel 401 points to the rear side at the meshing point with the rack chain 201. In this embodiment, Figure 1 and Figure 2 As shown, the rack wheel 401 rotates counterclockwise; then the rotation speed of the rack wheel 401 is accelerated until the pressure transmitted to the rear stopper 303 by the traveling wheel 402 is 0; S3. Perform a dynamic response test of the rack train. After the test is completed, return the adjustment platform to its original position, and drive the running wheel 402 to move and detach from the adjustment platform, thereby completing the dynamic response test of the rack train under the simulated slope.

[0049] In this embodiment, step S2 first rotates rack wheel 401 at a constant speed and then accelerates rack wheel 401. This eliminates the thermodynamic interference caused by the accelerated rotation of rack wheel 401 and directly separates the dynamic load increment caused by the inertial force. However, in actual testing, rack wheel 401 can also be accelerated first and then rotated at a constant speed, and this application does not impose any restrictions.

[0050] The above contents are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
