Description
Technical field
The utility model belongs to project security monitoring technical field, and in particular to connects to a kind of sleeve for safety monitoring
Connect bolt stress meters.
Background technique
Hydraulic and hydroelectric engineering is during practice of construction and is completed after operation, needs some stability of high slope situations of safety monitoring
And bolt stress meters are installed, it monitors stability of slope situation in real time, is influenced in actual installation anchor stress timing by objective condition, needed
It to be installed after the completion of construction and high altitude operation etc., one 4~8 meters of bolt stress meters length, conventionally employed butt welding, slot welding, side
Welding, the installation of traditional welding bolt stress meters have the following deficiencies: production one length, 4~8 meters of bolt stress meters it is time-consuming,
Consumptive material is big；It is influenced by working procedure arrangement, it is necessary to which installation in time, protection difficulty are big；It is influenced by construction environment, working face is narrow
Small, bolt stress meters can not be installed；Installation needs are overstaffed, uneconomical；Installation difficulty is larger, and success rate is difficult to ensure；System
It is inconvenient to make installation, and operation difficulty is big, the quality for installing bolt stress meters cannot guarantee that, the safety monitoring data of acquisition
It is untrue.
In project security monitoring technical field, the technical problem that currently need to urgently solve is to provide a kind of structure letter
Single, easy for installation, easy to operate, practical stress meter.
In order to improve site safety monitoring bolt stress meters installation success rate, special processing and fabricating sleeve connection anchor stress
Meter, improves good safety monitoring bolt stress meters installation efficiency, works well during practical application.
Summary of the invention
The technical problem to be solved by the utility model is to overcome the above-mentioned prior art, a kind of operation letter is provided
Just, the sleeve connection bolt stress meters for safety monitoring that installation is simple, quick, cost is relatively low, economic and practical.
Solving technical solution used by above-mentioned technical problem is:
Sleeve connection bolt stress meters are made of at least two bolt stress meters unit, the bolt stress meters unit are as follows:
One end of stress meter is coupled with the first anchor pole by the first swivel nut, and the other end of stress meter passes through the second swivel nut and the second anchor pole
Connection, stress meter are connected by cable with reading plotter.
The utility model uses the bolt stress meters unit being coupled to each other, and bolt stress meters unit is passed through using stress meter
Swivel nut couples with anchor pole, simplifies structure, improves the installation effectiveness of bolt stress meters, reduces production cost, at the same not by
Construction space influences, and environment influences, and ensure that quality.The utility model has structure simple, easy to operate, easy for installation, fast
Prompt, the advantages that production cost is low, economic and practical.The utility model can be used for the engineering technology such as water conservancy, highway, railway, municipal administration neck
Domain needs installation bolt stress meters technical field after being also used for high altitude operation, operation in narrow space, completion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Fig. 2 is the left view of Fig. 1.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figs. 1-2, the sleeve connection bolt stress meters for safety monitoring of the present embodiment are by the first anchor pole 1,
One swivel nut 2, stress meter 3, reading plotter 4, cable 5, the second swivel nut 6, the connection of the second anchor pole 7 are constituted.
The cylinder connection bolt stress meters of the present embodiment are made of 2 bolt stress meters units, with stress in installation process
Meter 3 inserts in the hole depth, to determine the specific number of bolt stress meters, it is ensured that bolt stress meters installation length, which meets design, to be wanted
It asks.
The bolt stress meters unit of the present embodiment are as follows: one end of stress meter 3 is joined by one end of screw thread and the first swivel nut 2
It connects, the other end of the first swivel nut 2 is coupled by screw thread with one end of the first anchor pole 1, and the other end of stress meter 3 passes through screw thread and the
One end of two swivel nuts 6 couples, and the other end of the second swivel nut 6 is coupled by screw thread with the second anchor pole 7, the first swivel nut 2 and the second spiral shell
Set 6 connects at the both ends of stress meter 3 with the first anchor pole 1, the second anchor pole 7 respectively, is tightened using torque spanner.Stress meter 3
It is connected by cable 5 with reading plotter 4, it is commodity available on the market that the reading plotter of the present embodiment, which uses stress sheet, can also
Using other types of reading plotter available on the market.When sleeve connection bolt stress meters are used for safety monitoring, when the first anchor
When stress variation occurs for the inside of bar 1 and the second anchor pole 7, stress meter 3 will be stretched or compress and be deformed, and deformation makes stress
The deformation that meter 3 is stretched or compresses, is transformed into vibratory string stress, changes the vibration frequency of vibratory string, frequency signal is through cable transmission
Reading plotter is arrived out, can measure stress suffered by anchor pole in measured structure object.
The above, the only preferred embodiment of the utility model, are not intended to limit the protection of the utility model
Range.
