Technical Field

[0001] The utility model relates to the technical field of static level instruments, in particular to a static level monitoring device. Background Art

[0002] Static leveling monitoring technology is an important high-precision measurement method in the field of engineering monitoring. It is widely used in the settlement monitoring of large structures such as bridges, dams, high-rise buildings, subway tunnels, etc. The traditional static leveling system mainly relies on the principle of liquid pressure transmission, and accurately measures the settlement or tilt change of the structure by monitoring the height difference of the liquid level between each measuring point. However, the installation and adjustment of such systems often require extremely high accuracy and stability to ensure the reliability of the measurement data.

[0003] Existing monitoring devices are generally equipped with level and height adjustment mechanisms in the form of threaded propulsion. However, in order to be able to separately level multiple positions of the device when adjusting the level and to improve the freedom and flexibility of the level adjustment, the multiple threaded rods used for propulsion drive in the adjustment mechanism are independently arranged, lacking a mechanism for transmitting synchronous driving force, and cannot be driven to rotate synchronously. As a result, when adjusting the overall height of the device, it is necessary to screw and drive multiple threaded rods in sequence, which makes the operation more cumbersome and inconvenient. Utility Model Content

[0004] In view of this, the utility model provides a static level monitoring device to solve the problem that when adjusting the overall height of the device, it is necessary to screw and drive multiple threaded rods in sequence in steps, which is troublesome and inconvenient to operate.

[0007] Four threaded propulsion shafts are rotatably installed on the horizontal support ring on the upper side, and the bottom end part of the threaded propulsion shaft is welded with a knob and a driving disk at upper and lower intervals; the part of the threaded propulsion shaft located above the knob is screwed with a threaded sleeve, and four universal balls are rotatably inlaid and connected with the top ends of the four threaded sleeves respectively; rubber driving pads and driven gears are fixed at the upper and lower ends of the vertical driving shaft respectively; a driving assembly is rotatably installed in the inner space of the base, and the driving assembly as a whole is composed of a bottom gear ring and a vertical rotating shaft welded to the center position of the gear ring, wherein a lifting ring is welded to the outer side of the bottom end of the gear ring, and the vertical rotating shaft is movably connected to the center position of the cross bracket; the gear ring is meshed with the four driven gears for transmission, and the four driven gears are in contact with the lifting ring; under normal circumstances, the four rubber driving pads are kept separated from the four driving disks, and the four rubber driving pads slide upward and are in contact with the four driving disks.

[0008] Furthermore,

[0009] The device body as a whole is composed of a liquid storage tank and a top cover and a bottom cover which are respectively inserted and fixed at the upper and lower ends of the liquid storage tank.

[0010] Furthermore,

[0011] The bottom of the bottom cover is welded with a horizontal tray with an enlarged diameter, and four vertical connecting rods are welded between the circumferential outer ring part of the horizontal tray and four universal balls.

[0012] Furthermore,

[0013] A liquid level sensor is threadedly fastened at the center of the top cover, and two air valves are symmetrically threadedly fastened at the outer ring of the top end of the top cover.

[0020] The utility model provides a static level monitoring device, which has the following beneficial effects:

[0021] When the utility model is in use, four threaded propulsion shafts, four threaded sleeves and four universal balls are arranged around the interval between the device body and the base, and the horizontality of at least four directions on the device body can be adjusted, which can improve the freedom of horizontal adjustment of the device body. The utility model is flexible to use, compatible with different complex leveling conditions, and has a wide range of applications.

[0022] In addition, when the four rubber driving pads are connected to the four driving disks by power coupling transmission, the driving assembly can synchronously rotate and drive the four driving disks and the four threaded propulsion shafts to implement a one-time rapid lifting and lowering adjustment of the overall height of the device body. This eliminates the trouble of having to twist the four threaded propulsion shafts step by step to adjust the overall height of the device body, and the operation is convenient and quick.

[0023] In addition, the four vertical drive shafts that can slide up and down and the four rubber drive pads actually constitute a power clutch mechanism between the drive assembly and the four threaded propulsion shafts.
