[0005] Furthermore, the wheel-supporting mechanism includes a slide rail connecting plate, a guide wheel bracket and a guide wheel. The slide rail connecting plate is fixedly connected to the top side surface or the support frame of the mounting frame through a plurality of countersunk screws. One end of the guide wheel bracket is slidably mounted on the slide rail connecting plate and locked by a hexagon socket screw.

One end of the two tension springs is respectively hinged to the two stop plates, and the other end is respectively hinged to the two sides of the guide wheel bracket, and the connection position is located at the end of the guide wheel bracket away from the guide wheel.

[0007] Furthermore, a pressure sensor is fixedly installed on the slide rail connecting plate located on the support frame, the pressure sensor is abutted against the end of the guide wheel bracket, and the pressure sensor is connected to an external alarm. When the pressure value of the pressure sensor reaches a preset value, the alarm sounds an alarm.

[0008] Furthermore, the roller assemblies include four, and the four roller assemblies are symmetrically distributed about the bottom center line of the mounting frame.

[0009] Furthermore, the roller assembly includes a fixed plate, a U-shaped frame and a roller. The fixed plate is fixedly installed on the bottom of the mounting frame.

[0011] Beneficial effects:

[0012] 1. In the present invention, by setting up the mounting frame and the four wheel mechanisms, the two wheel mechanisms on the top surface can be used to realize the installation positioning of the height of the two small rails, and the two wheel mechanisms on the side surface can be used to realize the positioning of the distance between the two small rails. There is no need to use a total station, the operation is convenient, and the installation quality and efficiency can be improved. During the specific installation, the four wheel mechanisms are assembled and connected with the mounting frame, and then the two wheel mechanisms on the top surface are placed on the two large rails, and the positions of the two wheel mechanisms on the side are adjusted so that they are rolled and connected with the sides of the two large rails that are close to each other. Finally, the mounting bolts of the small rail are adjusted to cooperate with the roller assembly, and the mounting bolts are locked.

[0013] 2. In the present invention, the position of the guide wheel can be easily adjusted through the arrangement of the slide rail connecting plate, the guide wheel bracket and the guide wheel, which facilitates the coordination between the guide wheel and the large track and can adapt to the use of large tracks of different widths and heights.

[0014] 3. In the present invention, through the setting of the pressure sensor and the alarm, the alarm signal of the alarm can be used to quickly and conveniently confirm whether the small track is installed in place, further improving the installation efficiency. The specific process is that before the small track is installed and fixed, due to the gravity of the installation frame, the pressure sensor has an initial pressure value. As the mounting bolts are adjusted, the small track will contact the roller assembly and support it. At this time, the gravity of the installation frame acting on the large track will be partially shared by the small track, thereby reducing the initial pressure value of the pressure sensor. Until the initial pressure value reaches the designed preset value, the alarm sends an alarm signal to confirm that the small track has been installed in place, where the preset value is the actual pressure value between the top wheel mechanism and the large track after the small track is installed and fixed. In the above process, after completing the installation of a section of small track, the alarm can be manually reset to facilitate the installation and fixation of the next section of small track.

[0015] 4. In the present invention, the symmetrical arrangement of the four roller assemblies can ensure the accurate installation and positioning of the two small tracks; the arrangement of the fixing plate, U-shaped frame and rollers can facilitate the adjustment of the spacing between the roller assemblies to meet the installation and fixation of small tracks of different widths; combined with the setting of the scale dimension line, the precise adjustment of the distance can be achieved.
