Description

Technical Field

[0001] The utility model belongs to the technical field of subway deformation monitoring, and in particular relates to an auxiliary device for subway deformation monitoring. Background Art

[0002] During subway construction, the changes in the main structure mainly follow the ground heave and subsidence. The repeated vibrations during subway operation and the unbalanced centrifugal force on the curve may induce the deformation of the tunnel body and the changes in the soil properties around the tunnel. The deformation monitoring of the subway generally includes deep horizontal displacement, strong internal force of the enclosure and settlement of underground pipelines. If it involves subway tunnels, there are also factors such as cracks, vault settlement, clearance convergence and segment deformation.

[0003] Subway deformation detection is an important means to ensure the safety of subway structures and prevent potential disasters. Displacement monitoring technology based on the Bassett convergence system is one of the detection amplifications: the monitoring unit is installed on the tunnel profile, and the deformation of the measuring ring causes the angle sensor to record the angle change, thereby calculating the displacement of the fixed point. However, the detection units in the existing technology are mostly fixed in a certain place. In actual applications, it is impossible to change the position conveniently and quickly according to the different detection positions. Utility Model Content

The housing 501 is fixedly connected with a battery 509, an electromagnet 510 and a motor 504. The output shaft of the motor 504 is fixedly connected with a driving gear 505. The surface of the driving gear 505 is meshed with a driven gear 506. The surface of the driven gear 506 is fixedly connected with a roller 508. The driven gear 506 and the roller 508 are sleeved with a pin 507. Both ends of the pin 507 are fixedly connected to the inner surface of the housing 501. By setting the track 1 and the moving mechanism 5, in actual applications, through the cooperation between the above, not only can the free change The position of the mobile mechanism 5 is changed so that the detection mechanism 6 can change its position quickly, thereby meeting the needs of various position detections, and different types of tracks 1 can be installed according to different actual needs. When a linear track 1 is installed, it can be freely assembled and extended, thereby increasing the movable area range of the mobile mechanism 5, thereby achieving the purpose of improving the detection area of ​​the detection mechanism 6. At the same time, under the action of the battery 509 and the electromagnet 510, a magnetic force is generated to attract the track 1, thereby fixing the position of the shell 501, avoiding the shaking of the shell 501, ensuring the stability of the detection mechanism 6, and thus ensuring the accuracy of the detection result. The protective mechanism 7 includes a fixed rod 701, one end of the fixed rod 701 is fixedly connected to a buffer plate 702, the surface of the buffer plate 702 is slidably connected to a frame 704, and the interior of the frame 704 is sleeved with a spring 703, and one end of the spring 703 is fixedly connected to the surface of the buffer plate 702. By setting the protective mechanism 7, in actual applications, the mobile mechanism 5 can be protected, thereby avoiding the mobile mechanism 5 from colliding with the two ends of the track 1 when moving to cause damage to the device, thereby ensuring the service life of the device.

[0020] Specifically, the detection mechanism 6 is fixedly connected to the adapter block 502, the fixing rod 701 is fixedly connected to the shell 501, the slider 503 is slidably connected inside the slide groove 2, the shell 501 overlaps the inner surface of the track 1, and the adapter block 502 overlaps the outer surface of the track 1.

[0021] Specifically, the track 1 is connected to the external tunnel wall through the extension plate 3 and the expansion screw 4. The shape of the track 1 is an arc, but not limited to an arc.

[0022] Specifically, there are two rollers 508 , and both rollers 508 are overlapped on the inner surface of the track 1 .

[0023] The working principle of the utility model is:

[0024] S1. When the device is used, firstly, a track 1 of a corresponding shape is taken according to different use requirements, and then the track 1 is fixed to the wall of the subway tunnel through the expansion wire and the extension plate 3. Since the moving mechanism 5 and the detection mechanism 6 are both arranged inside the track 1, the detection mechanism 6 can start the detection work. At the same time, if it is necessary to increase the detection range of the detection mechanism 6, it is only necessary to connect multiple tracks 1. The mutual connection between the tracks 1 only requires opening the two ends of the track 1. However, the two ends of the track 1 at the head and tail need to be in a closed state to prevent the moving mechanism 5 from sliding out of the track 1.

[0025] S2. When the position of the detection mechanism 6 needs to be changed, it is only necessary to turn on the motor 504 through the external controller, so that the motor 504 drives the driving gear 505 to rotate. Under the action of meshing, the driven gear 506 drives the roller 508 to rotate on the surface of the pin 507. Since the roller 508 is overlapped on the inner surface of the track 1, the rotation of the roller 508 will drive the shell 501 to move. Under the action of the slider 503 and the adapter plate, the detection mechanism 6 moves accordingly to achieve the purpose of adjusting the position of the detection mechanism 6. After moving to the designated location, the electromagnet 510 is powered by the battery 509 to generate magnetic force and attract the track 1, thereby fixing the position of the shell 501, avoiding the shaking of the shell 501, ensuring the stability of the detection mechanism 6, and thus ensuring the accuracy of the detection result;

[0026] S3. During the movement of the mobile mechanism 5, it may collide with the two ends of the track 1. In the event of a collision, the frame 704 will drive the spring 703 to perform a circular motion on the surface of the buffer plate 702 to weaken the impact force, thereby achieving the purpose of protecting the mobile mechanism 5.
