[0024] The technical solution of the present invention is further described below in conjunction with specific implementation methods:

[0025] like Figure 2 As shown, a retractable protective device for automatically monitoring the horizontal and vertical displacements of a railway roadbed comprises a metal base 1, a metal rod 2, a metal protective cover 3, a sliding mechanism 4 and a rotating mechanism 5. The metal rod 2 is connected to the metal base 1 via the rotating mechanism 5, the rotating mechanism 5 is connected to the back of a total station for railway inspection, the metal protective cover 3 is slidably connected to the metal rod 2 via the sliding mechanism 4, and the metal protective cover 3 covers the total station when it is lowered.

[0026] The metal base 1 is installed on the forced centering pier for horizontal displacement outside the foundation pit. Four fixing holes are evenly arranged circumferentially on the metal base 1 for installing expansion bolts. The metal base 1 is fixedly connected to the forced centering pier through the expansion bolts.

[0027] like Figure 3 As shown, in this embodiment, the metal base 1 is processed from a 1 cm thick stainless steel plate into a circular track with an outer diameter of 59 cm and an inner diameter of 48 cm.

[0028] like Figure 4 As shown, the rotating mechanism 5 includes a connecting frame 53, a bearing 52 and a roller 51. The roller 51 is slidably connected to the annular track. The center of the roller 51 is connected to the general end of the connecting frame 53 through the bearing 52. The other end of the connecting frame 53 is fixedly connected to the back of the total station, and the bottom end of the metal rod 2 is fixed to the connecting frame 53. The inner ring and the outer ring of the bearing 52 are connected to the roller 51 and the connecting frame 53 respectively, and the connecting frame 53 is fixed to the back of the total station, so that the rotating mechanism can be driven to rotate when the total station rotates, so that the metal rod 2 and the sliding mechanism 4 are always located at the back of the total station, which will not affect the monitoring.

[0029] In this embodiment, the metal rod 2 is made of a stainless steel rod with a diameter of 2 cm and a length of 90 cm.

[0030] The metal protective cover 3 is made of a 1 mm thick stainless steel plate, has a square horizontal cross section, a side length of 60 cm, a height of 1 m, and an opening at the bottom.

The screw rod 41 and the metal rod 2 are both arranged vertically, the side of the motor 44 is fixedly connected to the bottom end of the metal rod 2, the motor 44 is fixedly mounted on the connecting frame 53, the motor 44 is connected to the bottom end of the screw rod 41 by transmission, the slider 42 is provided with a screw hole matching the screw rod 41, the slider 42 is sleeved on the screw rod 41, the collar 43 is connected to the metal rod 2 by sliding, and the metal protective cover 3 is fixedly connected to the slider 42 and the collar 43. The device also includes a controller, which is electrically connected to the motor 44. The motor 44 is started by the controller to drive the screw rod 41 to rotate, so as to realize the lifting and lowering of the slider 42, thereby adjusting the height of the metal protective cover 3, and the collar 43 and the metal rod 2 play a role in limiting the moving direction of the slider 42. In order to prevent the slider 42 from detaching from the screw rod 41, a limit plate can also be installed on the top of the screw rod 41. When the metal protective cover 3 is lowered, it can protect the total station from wind and rain.

[0032] like Figure 1-4 As shown, a method for using a retractable protective device for automatically monitoring horizontal and vertical displacements of a railway roadbed comprises the following steps:

[0033] Step 1: The controller drives the sliding mechanism 4 to lift the metal protective cover 3;

[0034] Step 2: Install the metal base 1 on the forced centering pier through expansion bolts;

[0035] Step three, install the total station on the forced centering pier, and the back of the total station is fixedly connected to the rotating mechanism; install the device first and then the total station to prevent bumping into the instrument.

[0036] Step 4: lower the metal protective cover 3 to cover the total station;

[0037] Step 5: When used on site, the metal protective cover 3 is raised to the highest position through the controller, and then the total station starts to automatically measure the horizontal displacement and vertical displacement monitoring points of the railway roadbed.
