Description

Technical Field

[0001] The utility model relates to the technical field of roadbed monitoring devices, in particular to a roadbed deformation monitoring mark. Background Art

[0002] Roadbed deformation monitoring is a technical support to ensure the safe operation of railway operating equipment and facilities during the construction of adjacent railway operating lines.

[0003] At present, railway roadbed deformation monitoring signs are mostly made by digging a 15cm*15cm*15cm foundation pit on the shoulder, pouring cement mortar, and pre-embedding expansion bolts. Monitoring prisms are installed on the expansion bolts. The monitoring sign layout process is cumbersome, labor-intensive, and has low operating efficiency. At the same time, the monitoring signs are easy to loosen and fall off. Affected by external wind force, the monitoring signs are prone to skew, and the distribution state of the monitoring signs is not stable enough.

[0004] To this end, we propose roadbed deformation monitoring signs. Utility Model Content

[0005] The utility model mainly solves the technical problem that the distribution state of the above-mentioned monitoring marks is not stable enough, and provides a roadbed deformation monitoring mark.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a roadbed deformation monitoring sign comprises a settlement rod, an auger blade is arranged at the outer circle of the settlement rod, a countersunk head is arranged at the lower end of the settlement rod, a fixing block is fixedly installed on the settlement rod, a plurality of groups of handles are fixedly installed on the outer side surface of the fixing block, and a handle ring is fixedly installed at one end of the plurality of groups of handles away from each other;

[0007] A support plate is arranged at the upper end of the sinking rod, a connecting column is fixedly installed on the inner wall surface of the support plate, and an identification plate is fixedly installed on the connecting column.

[0008] Preferably, a flange is provided at the upper end of the sedimentation rod, and a gasket is sleeved on the outer circumference of the flange.

[0009] Preferably, a through opening is formed on the support plate, and the support plate is sleeved on the flange through the through opening. The support plate is detachably mounted on the upper end of the settlement rod through the cooperation of a fastening bolt and the flange.

[0010] Preferably, a movable clamping block is movably mounted on the flange via a rotating shaft, a torsion spring is provided on the rotating shaft, and a limiting protrusion is provided on the outer side surface of the movable clamping block.

[0011] Preferably, a limiting hole having a structure matching the limiting boss structure is formed through the support plate.

[0012] Beneficial Effects

[0013] The utility model provides a roadbed deformation monitoring sign, which has the following beneficial effects:

[0014] (1) When using the roadbed deformation monitoring sign, people hold the handle to conveniently insert the settlement rod into the detection point, and rotate the handle ring to drive the settlement rod to rotate and drill into the ground through the spiral drill blade. The spiral drill blade is set to make the settlement rod stably distributed at the detection point, avoiding the settlement rod from being skewed due to external wind force, thereby achieving the effect of improving the stability of the settlement rod distribution.

[0015] (2) The roadbed deformation monitoring sign is fixedly installed on the settlement rod by the support plate driven by the fastening bolts. The cooperation between the flange and the fastening bolts makes it convenient for people to install and remove the support plate, thereby achieving the effect of quickly installing the sign.

[0016] (3) When installing the signboard of the roadbed deformation monitoring sign, the movable clamp block is controlled to rotate to an upright position, and the support plate is set on the flange through the through-hole. At this time, the movable clamp block is distributed in an upright position inside the support plate. By flipping the movable clamp block, the movable clamp block is rotated to a horizontal position, so that the limiting boss pin on the movable clamp block is inserted into the inside of the limiting hole. By setting the movable clamp block, the installation of the support plate is further simplified, so that the support plate drives the signboard to be quickly installed on the settlement rod, thereby achieving the effect of further efficient installation of the signboard.

When in use, people hold the grip 8 to conveniently pin the sinker rod 1 to the detection point, and drive the sinker rod 1 to rotate by rotating the handle ring 4, so that the sinker rod 1 rotates and drills into the ground through the auger blade 2. The auger blade 2 is arranged to stably distribute the sinker rod 1 at the detection point, so as to prevent the sinker rod 1 from being skewed due to the influence of external wind force, etc.
