The safety monitoring displacement punctuation observation has the following defects:
firstly, the terrain observation is complex, the observation difficulty is high, the labor and the time are consumed;
secondly, the potential safety hazard exists, and the safety guarantee rate of personnel and equipment is low;
the observation prism is easy to damage, economic loss is caused, and the replacement difficulty is large;
fourthly, the observation prism is easy to damage, and the observation task is influenced;
disclosure of Invention
The utility model aims to solve the technical problem that overcome above-mentioned prior art not enough, provide an installation simple, convenient, swift, grasp easily, be applicable to the rotation type prism safety cover of all kinds of personnel's operation.
The technical scheme for solving the technical problems is as follows: the centering disc is fixed in concrete at a safety monitoring displacement mark point, a lower protective cover is arranged on the centering disc in a forced mode, an upper protective cover is rotatably sleeved on the inner upper portion of the lower protective cover, an observation hole is machined in one side face of the upper protective cover, a connecting rod is arranged in the center of the centering disc in a forced mode, a prism is arranged at the top of the connecting rod, and the prism is located in the protective cover and corresponds to the observation hole.
The utility model discloses an inside round rack that is provided with of lower safety cover forces upper portion to be provided with the gear bracing piece in the centering dish, and gear bracing piece upper portion is provided with the gear, and the gear bracing piece can rotate relatively with the gear, and the fixed safety cover that is provided with in gear upper portion, and the gear and rack mesh makes and goes up safety cover and lower safety cover and rotate relatively.
The utility model discloses an observation hole upper portion of going up the safety cover is provided with semi-circular guard plate.
The upper protective cover of the utility model is a hollow cylindrical structure with an opening at the lower part; the lower protective cover is a hollow cylindrical structure with an opening at the upper part.
Compared with the prior art, the utility model has the following advantages:
1. the method has wide application range and is suitable for monitoring the safety displacement of projects such as water conservancy projects, highways, railways, municipal works and the like;
2. the installation is simple, convenient and fast, and is easy to master, thus being suitable for various personnel to operate;
3. the prism is protected, labor is saved, time is saved, heavy work of repeated installation and disassembly is replaced, the observation prism is guaranteed not to be damaged due to influences of wind, frost, rain, snow, dangerous stones, wind, sand and the like, and the safe observation task is guaranteed to be smoothly carried out.
4. The actual operation is not influenced by objective conditions, climate and environment, and the method is safe, convenient and reliable;
5. simple manufacture, low manufacturing cost, economy and practicality.
