Guyed observation cabinet with cable displacement sensor

Release date: June 25, 2019 Hits: 159

Expansive soil or other soil slope engineering usually occurs horizontal relaxation, settlement and other deformation under internal load during construction and operation period, which has a great impact on the safety and stability of slope engineering. Therefore, it is very important to monitor the deformation of slope soil. At present, soil horizontal displacement monitoring methods mainly use inclinometer pipe deep displacement and surface observation pier displacement, while soil vertical displacement monitoring methods mainly use settlement ring and surface bench mark. At home and abroad, there is no special instrument and automatic instrument for monitoring horizontal relaxation deformation and settlement deformation at different horizontal positions of soil slope, and there is no monitoring equipment for large deformation of soil mass. Most of the existing measurement methods are manual measurement, so it is difficult to realize real-time monitoring and the monitoring effect is lag. At present, in order to cooperate with soil deformation monitoring, an observation cabinet is needed to record the degree of soil deformation.

summary of the invention

The purpose of the utility model is to provide a pull wire type observation cabinet for realizing the observation of deformation degree.

In the picture: constant tension rope Displacement sensor Al; constant force cable sensor mounting support A2; upper support plate A3; lower support plate A4; large pulley assembly A5; small pulley assembly A6; cabinet main column A7; positioning sleeve A8; positioning collar A9; cabinet side plate Al0; bottom plate all; top plate A12; wire body A13; hammer sleeve A14; hammer A15.

Specific implementation mode

The utility model is further described in detail with the attached drawings.

The utility model relates to a pull wire type observation cabinet, which comprises a cabinet body composed of main column A7, bottom plate al 1, top plate A12 and cabinet side plate Al0; the inner side of cabinet side plate Al0 is connected with upper support plate A3 and lower support plate A4; the upper end of upper support plate A3 is provided with several constant force pulling ropes Displacement sensor A constant force pulling rope sensor Al is arranged on the mounting support A2 of the constant tension rope displacement sensor. The constant force pulling rope sensor can be connected with MCU to realize the functions of recording, warning and remote transmission of monitoring results.

One end of a number of wire bodies A13 passes through the bottom plate AI; the line body A13 slides with the small pulley assembly A6 through the positioning collar A9; and the line body A13 is connected with the measuring line of the displacement sensor al of the constant tension rope through the knot. Line A13 passes through the bottom plate all and connects to other components to realize variant monitoring.

Preferably, the other end of the wire body A13 passes through the heavy hammer sleeve A14 and is connected with the counterweight A15, and is in sliding fit with the large pulley assembly A5; in this design, the tension on the wire body A13 can be increased as necessary, so that the tension is greater than the limit of the constant tension rope displacement sensor al.

Preferably, there are eight mounting supports A2 of constant tension rope displacement sensor and eight corresponding wire body A13.
