Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit monitoring, in particular to an inclinometer tube for foundation pit monitoring. Background Art

[0002] With the acceleration of urbanization, the number and scale of construction projects are constantly expanding. Especially for construction projects in urban central areas, due to the scarcity of land resources, it is often necessary to carry out difficult foundation pit construction on a small site. In order to ensure the safety of foundation pit construction, real-time monitoring of the foundation pit is very necessary. In the process of foundation pit monitoring, the inclinometer is a measuring tube pre-buried underground to observe the horizontal displacement inside the soil.

[0003] When using the existing inclinometer tube, there is a problem that the tube body is easily touched, resulting in measurement errors. At the same time, falling rocks, soil blocks, etc. can easily cause blockage to the device, affecting the measurement effect. Therefore, the existing device needs to be improved to meet actual needs.

[0029] Specifically, two groups of fixed frames 9 are relatively fixedly installed inside the pipe sleeve 1, and two groups of sliding rods 12 are relatively fixedly installed at the bottom end of the movable plate 13. Each group of sliding rods 12 penetrates and slides to connect one group of fixed frames 9, and the bottom end is respectively fixedly connected to the top of one group of connecting plates 11, and the outer peripheral surface of the operating rod 14 is slidably connected to the inside of the rubber sliding sleeve 18. The advantage is that first, the top of the operating rod 14 is held and pressed downward, and the operating rod 14 slides inside the rubber sliding sleeve 18. At the same time, the operating rod 14 drives the movable plate 13 to drive the two groups of sliding rods 12 downward, and the two groups of sliding rods 12 drive the two groups of connecting plates 11 to slide inside the corresponding fixed frames 9 and squeeze the spring 10 at the same time. At this time, the operating rod 14 drives the circular plate 15 downward to fit the block 17 with the groove 81 on the side of the circular groove 8, and the operating rod 14 is connected to the threaded rod 4. The threaded rod 4 rotates, and when the position of the threaded rod 4 is adjusted, the operating rod 14 is loosened to release the pressure of the spring 10 by the movable plate 13, the slide rod 12, and the connecting plate 11. The spring 10 rebounds, and each component is reset. The block 17 is disengaged from the slot 81. At this time, the threaded rod 4 is inside the pipe sleeve 1 and cannot be adjusted. The threaded rod 4 is prevented from accidentally touching the threaded rod 4 and causing the threaded rod 4 and the pipe body 5 to tilt. The pipe sleeve 1 is used to protect the threaded rod 4 and the pipe body 5 to prevent debris from entering.

[0030] Specifically, two groups of clamping blocks 17 are relatively fixedly installed on the side of the circular plate 15, and two groups of clamping grooves 81 are relatively opened on the side of the circular groove 8. The advantage is that when the operating rod 14 drives the circular plate 15 downward to drive the clamping block 17 downward, the clamping block 17 is embedded in the clamping groove 81, and the rocker 16 is rotated, so that the rocker 16 drives the operating rod 14 to rotate, and the operating rod 14 drives the circular plate 15 to drive the clamping block 17 to drive the threaded rod 4 to rotate inside the threaded groove 2, and the depth of the threaded rod 4 is adjusted, so that the threaded rod 4 drives the pipe body 5 to go deep into the foundation pit.

[0031] Specifically, a set of limiting plates 3 are fixedly installed at the bottom of the pipe sleeve 1, the inside of the limiting plates 3 is slidably connected to the outer peripheral surface of the pipe body 5, and a set of threaded rods 4 are threadedly connected inside the thread groove 2. The advantage is that the limiting plates 3 limit the top of the threaded rods 4, avoiding the continuous adjustment of the depth when the threaded rods 4 penetrate into the foundation pit and cannot be observed by the naked eye, so that the threaded rods 4 drive the pipe body 5 to separate from the pipe sleeve 1.

[0032] Specifically, a group of tapered rods 7 are fixedly installed at the bottom of the connecting flange 6. The advantage is that when the threaded rod 4 drives the pipe body 5 to penetrate into the foundation pit, the tapered rods 7 facilitate the device to drill holes at the bottom of the foundation pit, so as to facilitate the fixing of the device.

[0033] When in use, first hold the top of the operating rod 14 and squeeze the operating rod 14 downward. The operating rod 14 slides inside the rubber sliding sleeve 18. At the same time, the operating rod 14 drives the movable plate 13 to drive the two sets of sliding rods 12 downward. The two sets of sliding rods 12 drive the two sets of connecting plates 11 to slide inside the corresponding fixed frame 9 and squeeze the spring 10 at the same time. At this time, the operating rod 14 drives the circular plate 15 downward to fit the block 17 with the groove 81 on the side of the circular groove 8. The operating rod 14 drives the circular plate 15 downward to drive the block 17 downward. At the same time, the block 17 is embedded in the groove 81, and the rocker 16 is rotated so that the rocker 16 drives the operating rod 14 to rotate. The operating rod 14 drives the circular plate 15 to drive the block 17 to drive the threaded rod 4 to rotate inside the threaded groove 2, and the depth of the threaded rod 4 is adjusted, so that the threaded rod 4 drives the pipe body 5 to go deep into the foundation pit. When the position adjustment of the threaded rod 4 is completed , release the operating rod 14, so that the movable plate 13, the sliding rod 12, and the connecting plate 11 release the pressure of the spring 10, the spring 10 rebounds, the various components reset, and the block 17 disengages from the slot 81. At this time, the threaded rod 4 is inside the pipe sleeve 1 and cannot be adjusted to adjust the threaded rod 4, so as to avoid the problem that the threaded rod 4 accidentally touches the threaded rod 4 and the pipe body 5 is tilted. The pipe sleeve 1 protects the threaded rod 4 and the pipe body 5 to prevent debris from entering. The outer peripheral surface of the threaded rod 4 is slightly larger than the outer peripheral surface diameter of the pipe body 5 by one centimeter. The limit plate 3 limits the top of the threaded rod 4 to avoid continuous adjustment of the depth when the threaded rod 4 penetrates deep into the foundation pit and cannot be observed by the naked eye. The threaded rod 4 drives the pipe body 5 to disengage from the pipe sleeve 1. When the threaded rod 4 drives the pipe body 5 to penetrate deep into the foundation pit, the cone rod 7 is used to facilitate the device to drill a hole at the bottom end of the foundation pit, so as to facilitate the fixation of the device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
