Description

Technical Field

[0001] The utility model relates to the field of high roadbed slopes, in particular to a high roadbed slope monitoring device. Background Art

[0002] A high roadbed slope is a high slope located on both sides of the road, which is often a mountain structure or a high slope structure. Since it is close to the road surface, if the high slope becomes loose and causes mudslides or slope collapse, it will directly destroy the road surface. Therefore, the protection and monitoring of high roadbed slopes is particularly important, so that early warning can be given before collapse to avoid major accidents.

[0003] A Chinese patent discloses a roadbed high slope monitoring device (authorization announcement number CN 218270719 U). The patent technology fixes the positioning sleeve to the specified position of the installation column, so that the installation column can only be inserted into the roadbed high slope to a specified depth, ensuring that the entire device can normally achieve the detection purpose, and the operation is simpler and more convenient. However, when adjusting the position of the positioning sleeve, it is necessary to use a ruler to assist in measuring the position of the positioning sleeve in order to prepare to grasp the depth of the installation column inserted into the roadbed high slope, which is not convenient enough. At the same time, the installation column is inserted into the roadbed high slope without a structure to improve stability, which makes the installation stability of the installation column poor and makes the installation column easy to be pulled out. Therefore, a person skilled in the art provides a roadbed high slope monitoring device to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a roadbed high slope monitoring device, including a mounting column and a stabilizing seat, wherein a laser receiver is mounted on the upper portion of the outer surface of the mounting column, a through hole is provided in the lower portion of the inner portion of the mounting column, a threaded rod is rotatably connected inside the through hole, the threads of the upper and lower portions of the outer surface of the threaded rod are in opposite directions, a rotating rod is mounted on the upper end of the threaded rod, and the rotating rod passes through the mounting column, the outer surface of the threaded rod is symmetrically threaded with a threaded sleeve, and the threaded sleeve is slidably connected to the inner wall of the through hole, notches are provided at the left and right ends of the threaded sleeve, an extrusion block is rotatably connected inside the notch, and one end of the extrusion blocks on the upper and lower sides is rotatably connected to a protruding block;

[0005] A scale line is installed on the outer surface of the mounting column, and the outer surface of the mounting column is slidably connected to the stable seat. Hidden grooves are symmetrically arranged on the inner wall of the stable seat. The inside of the hidden grooves is slidably connected to the pull block. Several clamping blocks are installed on the inner end of the two pull blocks, and a pull rod is installed on the outer end of the two pull blocks. A spring is sleeved on the outer surface of the pull rod.

[0010] Preferably, the outer end surfaces of the two protruding blocks are spike-shaped.

[0011] Preferably, the pull rod passes through the stabilizing seat and is installed with a pull ring.

[0012] Technical effects and advantages of the utility model:

[0013] The utility model pushes the stabilizing seat to move on the outer surface of the installation column and fixes the position of the stabilizing seat according to the scale line, so that the installation column can be quickly controlled to be inserted only into the specified depth of the high slope of the roadbed, which is convenient and quick. Then, the two threaded sleeves are driven to move toward the middle by rotating the threaded rod, so that the extrusion blocks on both sides are turned outward, and at the same time, the extension block moves outward, so that the extrusion block and the extension block squeeze the land, thereby improving the installation stability of the installation column.

[0020] The working principle of the utility model is:

[0021] A mounting column 1 equipped with a laser transmitter is installed on the roadbed, and multiple mounting columns 1 equipped with laser receivers 2 are installed at equal distances on the high slope. The laser receiver 2 receives the laser signal emitted by the laser transmitter to achieve the purpose of distance measurement. At the same time, when the laser receiver 2 moves synchronously with the mounting column 1, the measured distance changes, thereby achieving the purpose of detecting the high slope of the roadbed;

[0022] During installation, the pull ring 15 and the pull rod 14 are used to pull the pull block 13 to move the compressed spring 16, and the pull block 13 drives the clamping block 17 to move and retract into the hidden groove 12, pushing the stabilizing seat 11 to move on the outer surface of the installation column 1, and adjusting the position of the stabilizing seat 11 according to the scale line 9. Then, the pull ring 15 is released, and the clamping block 17 is pushed to reset and insert into the clamping groove 10 through the spring 16, fixing the position of the column stabilizing seat 11, thereby quickly controlling the installation column 1 to be inserted into the high slope of the roadbed to a specified depth;

[0023] Then, the threaded rod 4 is driven to rotate by the rotating block and the rotating rod 5, and the threaded rod 4 drives the two threaded sleeves 6 to move toward the middle, so that the extrusion blocks 7 on both sides are flipped outward. At the same time, the extending block 8 moves outward, so that the extrusion block 7 and the extending block 8 extend out of the through hole 3 to squeeze the ground, thereby improving the installation stability of the mounting column 1.
