Description

Technical Field

[0001] The utility model relates to the technical field of ballastless track detection devices, in particular to a ballastless track structural layer detection device. Background Art

[0002] Ballastless track is a multi-layered structural system. Due to the effects of foundation deformation, rain, cyclic temperature gradients, etc., each layer of the ballastless track may produce vertical relative deformation, vertical absolute deformation and lateral inclination. These residual deformations will eventually be reflected in track irregularities, affecting driving comfort and the health of the ballastless track. To this end, many scholars have conducted theoretical, simulation and experimental research on the deformation transfer laws of track structure layers. However, these studies often lack the support and verification of measured data. Therefore, it is necessary and valuable to carry out detection of the vertical relative deformation, vertical absolute deformation and lateral inclination of the ballastless track structure layers.

[0003] A search revealed that publication number CN217378408U discloses a ballastless track structural layer detection device, comprising a rigid frame and a rigid step truss. A plurality of roller pairs are provided at the bottom of the rigid frame, and the roller pairs are positioned on the ballastless track. An intelligent analysis integration system and a strapdown inertial navigation system are provided on the rigid frame. The rigid step trusses are symmetrically arranged on both sides of the rigid frame. Several ranging sensors are provided on each rigid step truss, and the rigid step trusses on both sides are positioned on the same vertical plane as any wheel axle. The intelligent analysis integration system is connected to the strapdown inertial navigation system and the ranging sensors.

DETAILED DESCRIPTION

[0024] The following will combine 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, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example:

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] A ballastless track structural layer detection device includes a mobile frame 2 mounted on a ballastless track 1, the front and rear ends of the mobile frame 2 are rotatably connected to a rotating shaft 3, the left and right ends of two groups of rotating shafts 3 and located at the top of the ballastless track 1 are rotatably connected to rollers 4, the left and right ends of the mobile frame 2 are hinged with folding frames 5, the bottoms of the two groups of folding frames 5 are fixedly installed with multiple groups of ranging sensors 6, the front end of the top of the mobile frame 2 is fixedly installed with a buffer box 7, the interior of the buffer box 7 is installed with a buffer mechanism 8, the top of the buffer mechanism 8 is fixedly installed with a first adjustment frame 9, and the top of the first adjustment frame 9 is rotatably connected to a detection computer 10.

[0028] First, a motor 201 is fixedly installed at the front end of the mobile frame 2, and a driving wheel 202 is fixedly installed on the driving end of the motor 201. A driven wheel 203 is fixedly connected to the outer side of the rotating shaft 3. The driven wheel 203 is connected to the driving wheel 202 through a transmission belt 204. When the ballastless track 1 is inspected, the driving wheel 202 is driven to rotate by the motor 201, and the driven wheel 203 is driven to rotate under the transmission of the transmission belt 204, thereby driving the roller 4 to rotate through the rotating shaft 3, and then driving the mobile frame 2 to move on the ballastless track 1 to inspect various places.

[0029] Furthermore, a push rod 205 is fixedly installed at the rear end of the top of the mobile frame 2, and a second adjustment frame 206 is fixedly installed on the top of the mobile frame 2 and in front of the push rod 205. The top of the second adjustment frame 206 is rotatably connected to a seat 207. When driving the mobile frame 2 to move, the seat 207 is turned to the direction of the push rod 205. Sitting on the seat 207, holding the push rod 205 with your hands, you can move stably on the mobile frame 2.

[0030] Then, the first adjustment frame 9 and the second adjustment frame 206 are both composed of a support tube 901 and a telescopic rod 902. The telescopic rod 902 is slidably connected to the inside of the support tube 901. A fixed sleeve 903 is fixedly installed at the connection between the support tube 901 and the telescopic rod 902. The height of the seat 207 and the detection computer 10 is adjusted by adjusting the length of the telescopic rod 902, which is convenient for making corresponding adjustments according to different detection personnel. After the adjustment is completed, it is fixed by the fixed sleeve 903.

[0031] Furthermore, the two groups of folding frames 5 are staggeredly installed at the left and right ends of the mobile frame 2, and the ends of the two groups of folding frames 5 that are close to each other are fixedly connected to the first fixed block 501, and the positions on the left and right sides of the mobile frame 2 corresponding to the first fixed block 501 are fixedly connected to the second fixed block 502. The first fixed block 501 and the second fixed block 502 are fixed by a pin 503. When the ballastless track 1 is inspected, the two groups of folding frames 5 are located at the left and right ends of the mobile frame 2, and the pin 503 is inserted into the inner side of the first fixed block 501 and the second fixed block 502 to fix the folding frames 5. The inspection is carried out by multiple groups of distance measuring sensors 6. After the inspection is completed, the pin 503 is pulled out, and then the two groups of folding frames 5 are folded toward the top of the mobile frame 2, thereby reducing space occupancy and storing and protecting the distance measuring sensors 6 on the folding frames 5.

[0032] Secondly, the buffer mechanism 8 includes a buffer base 801 slidably connected to the top of the buffer box 7, a lifting plate 802 is fixedly installed at the bottom of the buffer base 801 and located inside the buffer box 7, and the left and right ends of the buffer box 7 are fixedly connected with slide rods 803, and the interiors of the two sets of slide rods 803 are slidably connected with sliding sleeves 804. The outer sides of the two sets of slide rods 803 and the ends away from the two sets of sliding sleeves 804 are both provided with springs 805, and transmission rods 806 are installed between the two sets of sliding sleeves 804 and the lifting plate 802. When the ballast track 1 is being inspected, the inspection computer 10 is located on the top of the first adjustment frame 9. After the moving frame 2 moves on the ballastless track 1 and generates vibration, the buffer base 801 moves up and down on the top of the buffer box 7, causing the lifting plate 802 to move up and down inside the buffer box 7. Under the transmission of the transmission rod 806, the sliding sleeve 804 is pushed to slide on the outside of the sliding rod 803, thereby pushing the spring 805 to buffer the vibration, thereby avoiding damage to the inspection computer 10, avoiding affecting the inspection results and ensuring the normal progress of the inspection.

[0033] Finally, the four corners of the bottom of the buffer base 801 are slidably connected to the buffer box 7 through connecting columns 807. Sealing sleeves 808 are installed inside the buffer box 7 and on the outside of multiple groups of connecting columns 807, and the connecting columns 807 are slidably connected to the sealing sleeves 808. The two ends of the transmission rod 806 are rotatably connected to the sliding sleeves 804 and the transmission rod 806 respectively. The buffer base 801 slides up and down on the top of the buffer box 7 through the connecting columns 807. At the same time, the sealing of the connection between the connecting columns 807 and the buffer box 7 is guaranteed by the sealing sleeves 808 to prevent the entry of external impurities and ensure the normal operation of the buffer mechanism 8 inside the buffer box 7.

[0034] In this embodiment, the implementation scenario is specifically as follows: when inspecting the ballastless track 1, the seat 207 is turned to the direction of the push rod 205, and the user sits on the seat 207 and holds the push rod 205 to move stably on the mobile frame 2. The mobile frame 2 moves on the ballastless track 1 to inspect various places. When inspecting the ballastless track 1, two sets of folding frames 5 are located at the left and right ends of the mobile frame 2, and the pins 503 are inserted into the inner sides of the first fixed block 501 and the second fixed block 502 to fix the folding frames 5. The detection is performed through multiple sets of distance measuring sensors 6. After the detection is completed, the pins 503 are pulled out, and then the two sets of folding frames 5 are folded toward the top of the mobile frame 2 to reduce space occupation while storing and protecting the distance measuring sensors 6 on the folding frames 5. When inspecting the ballastless track 1, the detection computer 1 0 is located on the top of the first adjustment frame 9. After the moving frame 2 moves on the ballastless track 1 and generates vibration, the buffer base 801 moves up and down on the top of the buffer box 7, so that the lifting plate 802 moves up and down inside the buffer box 7, and the sliding sleeve 804 is pushed to slide on the outside of the sliding rod 803 under the transmission of the transmission rod 806, thereby pushing the spring 805 to buffer the vibration. The whole operation process is simple and convenient. Compared with the existing ballastless track structure layer detection device, the utility model is designed to reduce space occupation after the detection is completed, while storing and protecting the distance measuring sensor 6 on the folding frame 5. At the same time, during the detection process, the vibration of the detection computer 10 is buffered, which can avoid damage to the detection computer 10 and avoid affecting the detection results, thereby ensuring the normal progress of the detection.
