Description

Technical Field

[0001] This utility model relates to the field of rail transit model testing technology, and specifically to a rail transit model testing device. Background Technology

[0002] Rail transit model testing refers to the process of evaluating and optimizing the entire lifecycle of a rail transit system, including its design, construction, operation, and maintenance, through a series of scientific and systematic experimental methods based on simulating the actual rail transit operating environment. This testing typically involves verifying, testing, and analyzing the physical or digital model of the rail transit system to ensure that the system's safety, reliability, and performance meet predetermined standards. Rail transit model testing equipment may include simulated environment structures, load-bearing platforms, deflection detection devices, etc., to simulate real rail transit operating conditions and to conduct rapid and accurate testing of the model.

[0003] A search of Chinese patent authorization (publication number: CN119309759A) discloses a rail transit model testing device, including a base plate, a support mechanism and a disassembly mechanism on top of the base plate. The support mechanism includes two fixed frames, the bottom surface of which is fixedly connected to the upper surface of the base plate. Fixed frames are fixedly connected to the front and back of both fixed frames. Two first forward and reverse motors are fixedly connected to the inner wall of one of the fixed frames. This rail transit model testing device, under the action of rotating threaded rods, can drive the moving blocks and moving plates on the surface to move, thereby adjusting the position of the support frame. Adjusting the distance between the support frame and the fixed frames can also change the support strength for the track body. Simultaneously, the electric telescopic rod can be extended, pushing the surface support frame upwards until it moves to the bottom of the track body for support.

[0004] However, in implementing the relevant technology, the above-mentioned rail transit model testing device has the following problems: the existing technology requires the operation of multiple disassembly and assembly mechanisms to disassemble and assemble the track body, resulting in low disassembly and assembly efficiency of the track body. Therefore, a rail transit model testing device is proposed. Utility Model Content

[0005] This utility model proposes a rail transit model testing device, which solves the problem in related technologies that require the operation of multiple disassembly and assembly mechanisms to disassemble and assemble the track body, resulting in low disassembly and assembly efficiency of the track body.

[0006] The technical solution of this utility model is as follows: A rail transit model testing device, comprising:

[0007] A base plate and a support plate fixedly installed on top of the base plate. A photoelectric deflectometer is fixedly installed on the top of the support plate, and a track body is inserted into the top of the support plate.

[0008] An elastic component is disposed on the top of the base plate, and a limiting plate is slidably connected to the outer side wall of the elastic component. A toothed plate is fixedly installed on one side of the limiting plate.

[0009] The gear is rotatably connected to the top of the base plate, and the gear meshes with the toothed plate.

[0010] A vertical rod is fixedly installed at the bottom of the track body, and one side of the limiting plate is engaged with one side of the vertical rod.

[0011] Preferably, a second track body is fixedly installed on the top of the support plate, and a test trolley is provided on the top of the second track body.

[0012] Preferably, the elastic component includes a support block, a slide rod, and a spring. The support block is located at the top of the base plate, the slide rod and the spring are located on both sides of the support block, the limiting plate is slidably connected to the slide rod, and one end of the spring is fixedly connected to the limiting plate.

[0013] Preferably, a limiting block is fixedly installed on one side of the limiting plate.

[0014] Preferably, a limiting groove is provided on one side of the vertical rod, and the limiting block is engaged with the limiting groove.

[0015] Preferably, the top of each support plate is provided with a rectangular groove, and the vertical rod is inserted into the rectangular groove.

[0016] Preferably, one side of the limiting plate is connected to a connecting plate via a damping pivot, and the top of the base plate is provided with a positioning groove.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] By using the elastic components, limiting plates, toothed plates, and gears, the movable limiting plates slide through the elastic components, driving the toothed plates to move. The toothed plates then drive the meshing gears to rotate, causing the two limiting plates to move closer to each other. This allows the vertical rod at the bottom of the track body to pass through the support plate, with the bottom end of the vertical rod contacting the top of the base plate. Releasing the limiting plates allows the elastic components to move the limiting plates back to their original position, and the limiting plates and vertical rods engage, quickly completing the installation of the track body. Conversely, the track body can be quickly disassembled, thus solving the problem of low efficiency in existing technologies that require multiple disassembly and assembly mechanisms.

Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1 - Figure 4 The present invention provides a rail transit model testing device, comprising:

[0027] The base plate 1 and the support plate 2 are fixedly installed on the top of the base plate 1. A photoelectric deflectometer 3 is fixedly installed on the top of the support plate 2, and a track body 4 is inserted into the top of the support plate 2.

[0028] Elastic component 5 is set on the top of the base plate 1. The outer side wall of the elastic component 5 is slidably connected to the limiting plate 6. A toothed plate 7 is fixedly installed on one side of the limiting plate 6.

[0029] Gear 8 is rotatably connected to the top of base plate 1, and gear 8 is meshed with toothed plate 7;

[0030] Vertical rod 10 is fixedly installed at the bottom of track body 4, and one side of limiting plate 6 is engaged with one side of vertical rod 10.

[0031] The elastic component 5 includes a support block 51, a slide rod 52 and a spring 53. The support block 51 is located on the top of the base plate 1. The slide rod 52 and the spring 53 are located on both sides of the support block 51. The limiting plate 6 is slidably connected to the slide rod 52. One end of the spring 53 is fixedly connected to the limiting plate 6.

[0032] One side of the limiting plate 6 is connected to the connecting plate 15 via a damping shaft, and the top of the base plate 1 is provided with a positioning groove 16.

[0033] In use, the movable limiting plate 6 slides and compresses the spring 53 via the slide rod 52. The limiting plate 6 drives the toothed plate 7 to move, and the toothed plate 7 drives the meshing gear 8 to rotate, causing the two limiting plates 6 to move closer to each other. At this time, the limiting plate 6 will drive the connecting plate 15 to move to the top of the positioning groove 16. The rotating connecting plate 15 is located in the positioning groove 16. After the limiting plate 6 is released, the positioning groove 16 cooperates with the connecting plate 15 to limit the limiting plate 6. The vertical rod 10 at the bottom of the track body 4 passes through the support plate 2, and the bottom end of the vertical rod 10 contacts the top of the bottom plate 1. The rotating connecting plate 15 separates from the positioning groove 16 to release the limitation on the limiting plate 6. The spring 53 drives the limiting plate 6 to slide back to its original position via the slide rod 52, so that one side of the limiting plate 6 is engaged with one side of the vertical rod 10, completing the quick installation of the track body 4. Conversely, the track body 4 can be quickly disassembled.

[0034] Specifically, a second track body 13 is fixedly installed on the top of the support plate 2, and a test trolley 14 is set on the top of the second track body 13.

[0035] The test trolley 14 is started and moves from the second track body 13 to the first track body 4. The test trolley 14 is a mature existing technology and will not be described in detail. The photoelectric deflectometer 3 is a precision instrument that uses the photoelectric effect for non-contact measurement. It focuses a laser beam into a tiny spot through an optical system. This focused spot is irradiated onto the surface of the structure under test. When the structure bends or deflects, the position of the spot also changes. The reflected light is guided back into the sensor, which can detect the change in deflection of the first track body 4.

[0036] Specifically, a limiting block 9 is fixedly installed on one side of the limiting plate 6, and a limiting groove 11 is opened on one side of the vertical rod 10, with the limiting block 9 and the limiting groove 11 engaging with each other.

[0037] When one side of the limiting plate 6 engages with one side of the vertical rod 10, the limiting block 9 is engaged in the limiting groove 11.

[0038] Specifically, a rectangular groove 12 is provided through the top of each support plate 2, and the vertical rod 10 is inserted into the rectangular groove 12.

[0039] When installing the track body 4, the vertical rod 10 at the bottom of the track body 4 passes through the rectangular groove 12, so that the bottom end of the vertical rod 10 contacts the top of the base plate 1, which initially limits the position of the track body 4 to facilitate installation.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
