[0002] With the rapid development of high-speed railways and the continuous increase in train operation speed, the requirements for train safety and stability are increasing day by day. Therefore, it is necessary to ensure the smoothness of the train operation track. For this reason, it is necessary to use a high-speed comprehensive inspection train to conduct daily inspections on the track conditions and ensure that its conditions meet the usage requirements.

[0003] The track detection system (abbreviation: track inspection system) is one of the important detection systems of a high-speed comprehensive inspection train, which can detect track geometric parameters, including items such as track alignment, gauge, level, elevation, cross-level, and car body acceleration. The track inspection system mainly includes an inertial component, a laser imaging component, a car body acceleration component, an elevation measurement component, and a track stiffness unevenness detection device, etc. The track detection equipment installation beam (abbreviation: track inspection beam), as an important carrier of the track detection system, needs to meet the installation requirements of the track inspection system components. The rationality of its structural design directly affects the accuracy of the track inspection equipment detection results. At present, the traditional track inspection beam for high-speed inspection vehicles belongs to the design structure of the first-generation track inspection system. The track inspection beam of the track inspection system is relatively heavy, and the components are greatly affected by vibration and impact during actual operation, which is not conducive to the accuracy of the detection equipment results and the structural strength; at the same time, the detection equipment includes many components and the installation method is complex.

[0004] Therefore, based on the above problems, there is an urgent need to provide a track inspection beam for a high-speed comprehensive inspection train track detection equipment that meets the installation requirements of the track inspection equipment and the strength requirements, and a detection equipment installation method. Summary of the Invention

[0060] At the top end of the hanging seat 10, the upper layer plate 11 of the hanging seat 10 extends horizontally to the outside of the vertical plate 12 and forms an L-shaped mounting surface with the vertical plate 12. Both the upper side plate of the hanging seat 10 and the vertical plate 12 are fixedly connected to the bogie through bolts 51. Between the bottom end of the hanging seat 10 and the cross beam 20, they are fixedly connected through a connecting component 50 in a detachable manner. In order to reduce the influence of the impact and vibration during the train operation on the detection equipment, an elastic member 53 is provided between the hanging seat 10 and the cross beam 20. The elastic member 53 can be an elastic rubber block or a rubber pad.

[0061] The connecting component 50 includes a bolt 51 and a gasket 52, a sleeve 54, a nut 55, which are sequentially sleeved on the bolt 51, and an elastic member 53 sleeved outside the sleeve 54.

[0062] In the above technical solution, the track inspection beam for the high-speed comprehensive inspection train provided by the present invention has the following beneficial effects:

[0063] The upper surface of the cross beam 20 of the track inspection beam contacts the hanging seat 10 through the adjusting pad 30 and is fixedly connected by the connecting component 50. Among them, the connecting component 50 has an elastic member 53 for abutting against and absorbing vibration on the upper surface of the hanging seat 10. The first installation surface 100 is arranged in the middle of the upper surface of the cross beam 20, and the lower surface symmetrically forms a downward protruding installation part 22. The side part of the installation part 22 forms a second installation surface 200 that extends obliquely from the center of the bogie towards the track direction. The track inspection equipment is installed through the first installation surface 100 and the second installation surface 200. The overall structure of the track inspection beam is lightweight, meeting the installation and inspection requirements of the track inspection system equipment. The installation height of the equipment can be adjusted according to the wheel wear condition. The overall structural weight is reduced by 27.5 kg compared with the original structure, and the strength meets the requirements. An elastic member is provided to attenuate vibration. The installation methods of the cross beam, the hanging seat, and the inspection equipment are simple in structure and high in reliability.

[0064] The invention provides an installation method based on the above track inspection beam for the high-speed comprehensive inspection train. The method includes the following steps:

[0065] S1: The first installation surface 100 on the cross beam 20, the cushion block 25 on the second installation surface 200, and the hoisting area 300 are all machined surfaces to ensure the dimensional tolerance of the installation equipment plane and the dimensional tolerance of the installation plane between the cross beam 20 and the hanging seat 10.

[0066] S2: The bolt 51 is sequentially sleeved with the gasket 52 and the sleeve 54. The elastic member 53 is sleeved outside the sleeve 54. The bolt 51 is placed in the installation holes of the cross beam 20 and the hanging seat 10. The top end of the elastic member 53 abuts against the gasket 52, and the bottom end abuts against the hanging seat 10. The sleeve 54 is inserted into the installation holes of the hanging seat 10, multiple adjusting pads 30, and the cross beam 20 from top to bottom in sequence. The bolt 51 passes through the hanging seat 10, the cross beam 20, and the cushion plate 40 below the cross beam 20 and then installs the nut 55. There is a gap between the bottom end of the sleeve 54 and the cushion plate 40. The end of the bolt 51 is inserted with an anti-detachment pin. The top end of the hanging seat 10 is fixedly connected to the bogie through the bolt 51 using the auxiliary installation seat interface reserved on the side beam of the frame.

[0067] Specifically, the top end of the elastic member 53 abuts against the gasket 52, and the bottom end abuts against the suspension seat 10. The length of the sleeve 54 is greater than that of the elastic member 53. The installation of the sleeve 54 can appropriately compress the rubber block. A plurality of adjusting pads 30 are provided between the suspension seat 10 and the cross beam 20. The compression size of the rubber block is adjusted by pre-adjusting the thickness of the adjusting pad 30, so as to ensure that the rubber block has an appropriate vertical stiffness. Among them, a backing plate 40 is provided between the surface of the cross beam 20 and the nut 55. The sleeve 54 can sequentially penetrate through the adjusting pad 30 and the mounting hole on the cross beam 20. There is a gap between the bottom end of the sleeve 54 and the backing plate 40. After the nut 55 is installed, a pin is inserted at the end of the bolt 51 to prevent the nut 55 from loosening;

[0068] S3: During the operation of the inspection vehicle, the wheels will wear as the operation mileage increases, and the wheel diameter will decrease. To ensure the installation position of the equipment from the rail surface, the height of the track inspection beam needs to be adjusted. An adjusting pad 30 is provided between the cross beam 20 and the suspension seat 10, and the height can be adjusted according to the actual operation conditions. When removing the adjusting pad 30, a gasket 52 with a corresponding thickness needs to be added between the rubber block and the sleeve 54 as Figure 4 shown.

[0069] The top ends of the suspension seats 10 at both ends of the cross beam 20 are connected to the bogie through bolts 51 using the auxiliary mounting seat interfaces reserved on the side beam of the frame;

[0070] S4: The track inspection equipment mainly includes an inertial component 60 and a laser imaging component 70. The inertial component 60 includes an outer cover installed on the horizontal first mounting surface 100 above the middle of the cross beam 20 through a bolt 51 fastener, and the laser imaging component 70 is installed on the inclined second mounting surface 200 of the lower mounting part 22 of the cross beam 20 through a bolt 51 fastener. The installation method is simple and convenient, as Figure 5 shown;

[0071] An installation method designed by the present invention, based on the above-mentioned track inspection beam for high-speed comprehensive inspection trains, has the same beneficial effects as the track inspection beam, and will not be elaborated here one by one.

Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
