Description

Technical Field

[0001] This utility model relates to the field of engineering surveying, specifically to a retractable protection device for automatic monitoring of horizontal and vertical displacement of railway subgrade. Background Technology

[0002] In the automated monitoring of railway subgrade, the horizontal and vertical displacements are monitored every two hours, requiring the total station to be permanently installed on the forced centering pier. However, current total stations lack protective devices, making them susceptible to damage in severe weather, thus affecting their lifespan and hindering long-term effective operation. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a retractable protection device for automatic monitoring of horizontal and vertical displacement of railway subgrade.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A retractable protection device for automatic monitoring of horizontal and vertical displacement of railway subgrade includes a metal base, a metal rod, a metal protective cover, a sliding mechanism, and a rotating mechanism. The metal rod is connected to the metal base through the rotating mechanism, and the rotating mechanism is connected to a total station used for railway testing. The metal protective cover is slidably connected to the metal rod through the sliding mechanism, and covers the total station when the metal protective cover is lowered.

[0006] As a preferred technical solution, the metal base is installed on the horizontal displacement forced centering pier outside the foundation pit. The metal base has four fixing holes evenly arranged around the circumference, and expansion bolts are installed in the fixing holes. The metal base is fixedly connected to the forced centering pier through the expansion bolts.

[0007] As a preferred technical solution, the metal base is a ring track, and the rotating mechanism includes a connecting frame, a bearing and a roller. The roller is slidably connected to the ring track, and the center of the roller is connected to one end of the connecting frame through the bearing. The other end of the connecting frame is fixedly connected to the back of the total station, and the bottom end of the metal rod is fixed on the connecting frame.

[0008] As a preferred technical solution, the sliding mechanism includes a motor, a lead screw, a slider, and a collar. Both the lead screw and the metal rod are arranged vertically. The side of the motor is fixedly connected to the bottom end of the metal rod, and the motor is drivenly connected to the bottom end of the lead screw. The slider has a screw hole that matches the lead screw, and the slider is sleeved on the lead screw. The collar is slidably connected to the metal rod, and the metal protective cover is fixedly connected to the slider and the collar.

[0009] As a preferred technical solution, the metal substrate, metal rod, metal protective cover, and sliding mechanism are all made of stainless steel.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The retractable protection device for automatic monitoring of horizontal and vertical displacement of railway subgrade of the present invention uses a rotating mechanism to keep the main components of the device always behind the total station, so as not to affect the monitoring process. The height of the metal protective cover can be adjusted by a metal rod and a sliding mechanism. When not in use, the metal protective cover is lowered to cover the total station, thereby protecting the total station from damage caused by rain and snow. When measuring, the metal protective cover is raised and the total station starts automatic monitoring, thereby ensuring that the instrument can work effectively for a long time.

[0017] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0018] like Figure 2 As shown, a retractable protection device for automatic monitoring of horizontal and vertical displacement of railway subgrade includes 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 through the rotating mechanism 5, and the rotating mechanism 5 is connected to the back of a total station used for railway testing. The metal protective cover 3 is slidably connected to the metal rod 2 through the sliding mechanism 4. When the metal protective cover 3 is lowered, it covers the total station.

[0019] like Figure 3 As shown, in this embodiment, the metal substrate 1 is made of a 1cm thick stainless steel plate and processed into a ring track with an outer diameter of 59cm and an inner diameter of 48cm.

[0020] 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 circular track. The center of the roller 51 is connected to the general end of the connecting frame 53 via the bearing 52. The other end of the connecting frame 53 is fixedly connected to the back of the total station. The bottom end of the metal rod 2 is fixed to the connecting frame 53. The inner and outer rings of the bearing 52 are connected to the roller 51 and the connecting frame 53, respectively. The connecting frame 53 is fixed to the back of the total station, which allows the rotating mechanism to rotate when the total station rotates, ensuring that the metal rod 2 and the sliding mechanism 4 are always located on the back of the total station and do not affect monitoring.

[0021] In this embodiment, the metal rod 2 is made of stainless steel rod with a diameter of 2cm and a length of 90cm.

[0022] The metal protective cover 3 is made of 1mm thick stainless steel plate, with a square horizontal cross section, a side length of 60cm, a height of 1m, and an opening at the bottom.

[0023] like Figure 1 As shown, the sliding mechanism 4 includes a motor 44, a lead screw 41, a slider 42, and a collar 43, all made of stainless steel. The lead screw 41 and the metal rod 2 are both vertically oriented. 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 and is driven by the bottom end of the lead screw 41. The slider 42 has a threaded hole matching the lead screw 41 and is fitted onto the lead screw 41. The collar 43 is slidably connected to the metal rod 2. 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 controller starts the motor 44, driving the lead screw 41 to rotate, thus raising and lowering the slider 42, thereby adjusting the height of the metal protective cover 3. The collar 43 and the metal rod 2 restrict the movement direction of the slider 42. To prevent the slider 42 from detaching from the lead screw 41, a limiting plate can also be installed on the top of the lead screw 41. When the metal protective cover 3 is lowered, it serves to protect the total station from wind and rain.

[0024] like Figure 1-4 As shown, a method for using a retractable protection device for automatic monitoring of horizontal and vertical displacement of railway subgrade includes the following steps:

[0025] Step 1: The metal protective cover 3 is raised by driving the sliding mechanism 4 through the controller;

[0026] Step 2: Install the metal base 1 onto the forced centering pier using expansion bolts;

[0027] Step 3: Install the total station on the forced centering block, with the back of the total station fixedly connected to the rotating mechanism; install the device first, then the total station, to prevent the instrument from being bumped or damaged.

[0028] Step 4: Lower the metal protective cover 3 to cover the total station;

[0029] Step 5: When using the instrument on site, raise the metal protective cover 3 to its highest position using the controller, and then the total station will automatically start measuring the horizontal and vertical displacement monitoring points of the railway subgrade.

[0030] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art can make non-inventive modifications to this embodiment as needed, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
