Abstract
Description
Technical Field
[0001] This utility model relates to the field of inertial navigation equipment installation technology, and in particular to an inertial navigation trolley system inertial navigation mounting base, mounting shell and mounting base. Background Technology
[0002] With the advancement of high-speed railways, the requirements for the speed and accuracy of track irregularity detection and adjustment are becoming increasingly stringent. Currently, both domestically and internationally, track inspection instruments are widely used for rail laying and adjustment, as well as long rail adjustments (joint commissioning and testing), achieving a measurement efficiency of 200 meters per day. However, track inspection instrument operation has extremely high environmental requirements, must be carried out during off-peak hours, and must be coordinated with CPIII for subsequent intersection measurements. While large-scale equipment such as track inspection vehicles offers high measurement efficiency, they are prohibitively expensive, making them unaffordable for ordinary track maintenance sections; only large railway bureaus can afford them. This inefficiency and high cost make railway construction schedules extremely tight, which is detrimental to both construction and subsequent maintenance. Therefore, there is a need to develop a portable, intelligent, efficient, and high-precision INS / GNSS-based rapid and precise measurement system for track geometry, applicable to the entire process of ballastless track construction, including high-speed railway construction, track completion acceptance, and operation and maintenance of existing lines. Supported by hardware platforms and software algorithms, this system could achieve integrated detection of railway track smoothness at high speeds and could also be used for monitoring subgrade settlement, deformation, and displacement. Existing inertial navigation trolley systems for this type of system have large and heavy housings and mounting bases, making manual handling and disassembly inconvenient. Furthermore, most systems do not employ a detachable design, hindering the disassembly, installation, and manual transportation of the housing and base containing the inertial navigation equipment. Therefore, there is an urgent need for an inertial navigation trolley system with an inertial navigation mounting base, housing, and mounting base that are easy to disassemble, install, and transport manually.

[0034] Example 2
[0035] Please see Figure 3 This embodiment 2 provides an inertial navigation system mounting housing for an inertial navigation vehicle system, including a top cover 1, a housing 3, a handle 2, and an inertial navigation housing connecting plate 11. The inertial navigation equipment is installed inside the housing. The top cover 1 is located at the top of the housing. The handle 2 is fixedly connected to the upper surface of the top cover 1. The bottom 14 of the housing is fixedly connected to the inertial navigation housing connecting plate 11, which is trapezoidal. The handle 2 facilitates easy installation, disassembly, and manual transport of the inertial navigation mounting housing. The bottom of the housing is fixedly connected to the inertial navigation housing connecting plate 11 by pins, forming a whole unit that can be installed on the inertial navigation mounting base of embodiment 1.
[0036] In this embodiment 2, the bottom of the inertial navigation housing connecting plate 11 is provided with a limiting plug 12. Preferably, the limiting plug is a pin 12. One side of the inertial navigation housing connecting plate 11 is also provided with a limiting groove to cooperate with the limiting protrusion 15 on the side of the first fixing block 5 in embodiment 1.

[0038] In this embodiment 2, a number of operation buttons are provided on one of the outer shell side plates 4 of the outer shell 3 to facilitate the recording and collection of various data during inertial navigation operations.
[0039] Example 3
[0040] Please see Figures 1-4 This embodiment 3, based on embodiments 1 and 2, provides an inertial navigation vehicle system inertial navigation mounting base, including: an inertial navigation vehicle system mounting base as described in embodiment 1 and an inertial navigation vehicle system mounting shell as described in embodiment 2. The inertial navigation shell connecting plate 11 is located between the first fixing block 5 and the second fixing block 6. The limiting protrusion 15 is connected to the limiting groove on the side of the inertial navigation shell connecting plate 11, and the clamping block 7 abuts against the inertial navigation shell connecting plate 11.
[0041] In a preferred embodiment, the first fixing block 5, the second fixing block 6, and the inertial navigation housing connecting plate 11 are all trapezoidal, and the three can be fitted together.
[0042] The inertial navigation system mounting base plate 10 between the first fixing block 5 and the second fixing block 6 is also provided with a limiting hole 13, which is connected to the pin 12 for further fixing.
[0043] The first fixing block 5 and the second fixing block 6 are respectively fixed to the inertial navigation system mounting base plate 10 by pins and screws. The recessed part of the second fixing block 6 can fit into the clamping block 7. One end of the rotating handle 8 is fixed to the inside of the clamping block 7 by screws. By rotating the rotating handle 8, the clamping block 7 can be moved back and forth along the center direction of the inertial navigation system mounting base plate 10, and the clamping and separation of the clamping block 7, the second fixing block 6, and the inertial navigation system housing connecting plate 11 can be achieved. When the clamping block 7 and the second fixing block 6 are clamped together, the entire inertial navigation system mounting shell can be lifted by the handle 2. The entire shell is further limited by the engagement of the pin 12 and the limiting hole 13, and the limiting protrusion 15 on the side of the first fixing block 5 and the limiting groove (not shown in the figure) on the side of the inertial navigation system housing connecting plate 11. The inertial navigation system mounting shell is then limited and installed on the inertial navigation system mounting base plate 10. On the base, the directional limit of the entire inertial navigation system (INS) mounting housing is achieved. At this time, the rotating handle 8 can be rotated to move the clamping block 7 forward along the center of the INS mounting base plate 10 and press against the side of the INS housing connecting plate 11, further fixing the entire INS mounting housing. This ensures that the clamping block 7 and the INS mounting base plate 10 are tightly fitted. At this time, the entire INS mounting housing is fixed in place and will not move forward, backward, left, or right. The INS trolley system can then be operated to obtain the required data. After the operation is completed, the rotating handle 8 can be rotated in the opposite direction to make the clamping block 7 embed into the recessed part of the second fixing block 6 and fit against it. At this time, there is a gap between the clamping block 7 and the INS housing connecting plate 11. The entire INS mounting housing can be removed using the handle 2. This process is the disassembly and installation process of the entire INS mounting housing and the INS mounting base in the INS mounting base.
[0044] In summary, this utility model designs an inertial navigation mounting shell and an inertial navigation mounting base for installing small inertial navigation devices. The inertial navigation mounting shell and the inertial navigation mounting base are connected by limiting grooves, limiting protrusions, limiting holes, and limiting plugs to form an inertial navigation mounting base. The disassembly and installation of the inertial navigation mounting shell and the inertial navigation mounting base can be achieved simply by opening the limiting plug and controlling the rotation of the handle to separate or attach the clamping block from the inertial navigation shell connecting plate. This greatly improves the convenience of disassembly and installation of the inertial navigation mounting shell and the inertial navigation mounting base. Based on the premise of small inertial navigation devices, this invention designs an inertial navigation mounting shell, an inertial navigation mounting base, and the inertial navigation mounting base composed of the two, achieving the purpose of small overall size and light weight, reducing the burden of manpower.
[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
