Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a hydrostatic level mounting device. Background Technology

[0002] A hydrostatic leveling system is a precision instrument used to measure relative elevation changes between two or more points. A hydrostatic level consists of components such as a liquid cylinder, float, precision level gauge, and protective cover. Figure 4 As shown, the hydrostatic leveling system includes a liquid storage tank 1. By connecting multiple hydrostatic levels 2 in series, based on the principle that the liquid levels in communicating vessels are equal, the liquid levels in all the storage tanks are at the same horizontal level. The hydrostatic level 2 is generally fixed on the object being measured. When the object settles, the hydrostatic level 2 settles accordingly. At this time, the absolute height of the liquid level does not change. Therefore, for the hydrostatic level 2, the relative change value of the liquid level inside it is equivalent to the settlement value of the hydrostatic level 2. Therefore, by using the hydrostatic level 2, the settlement value of multiple points can be measured quickly and conveniently.

[0003] Most existing static level instruments are installed directly on the object being measured using brackets. When used to measure the settlement of railway or subway tracks, the static level instrument is easily affected by passing vehicles, causing fluctuations and affecting the stability of the system. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a static level installation device.

[0005] This utility model provides a static level mounting device, including a base plate, a shock-absorbing mechanism, a mounting screw, a support nut, a mounting housing, and a clamping nut. The bottom edge of the mounting housing has mounting lugs adapted to the mounting screw. A shock-absorbing mechanism is arranged on the base plate opposite to the mounting lugs. The mounting screw is fixed to the top surface of the shock-absorbing mechanism. The support nut is screwed onto the mounting screw. The mounting housing is set on the mounting screw via the mounting lugs and leveled by the support nut before being locked by the clamping nut. The static level is installed in the mounting housing.

[0006] Compared with the prior art, the beneficial effect of this utility model is that it reduces the vibration force transmitted to the static level when the vehicle passes by by using a shock-absorbing mechanism, thereby reducing the fluctuations caused by the influence of oncoming vehicles.

[0007] Optionally, the shock absorption mechanism includes a base plate, on which a rubber washer is fixed. A top plate is fixed to the top surface of the rubber washer.

A support sleeve is provided on the top surface of the base plate and placed in the vertical through hole. A support rod is provided on the bottom surface of the top plate and placed in the vertical through hole. The support rod is inserted into the support sleeve.

[0008] Optionally, a fixing plate is also included, and a lifting mechanism is provided between the fixing plate and the base plate.

The static level 2 is installed in the mounting housing 7.

[0022] During implementation, the mounting box 7 is a rectangular box structure with an open front door. After the static level instrument 2 is installed, it can be sealed with a side plate and screws that are compatible with the open door. The mounting box 7 can also provide some protection for the static level instrument 2. The mounting box 7 is also provided with through holes for the air pipe and water pipe to pass through. Gaskets are set at the through holes to prevent scratches when the pipes are inserted.

[0023] In implementation, the shock absorption mechanism 4 includes a base plate 10, on which a rubber washer 11 is fixed. A top plate 12 is fixed to the top surface of the rubber washer 11. The rubber washer 11 has a vertical through hole 13, the axis of which coincides with the axis of the rubber washer 11.
