Description
Technical Field
The utility model belongs to the technical field of the architectural survey, especially, relate to an universal joint survey pole to one side.
Background
In the foundation ditch excavation work progress, probably take place the foundation ditch and collapse, have very big potential safety hazard, in order to guarantee the safety of engineering, so in the foundation ditch excavation construction, deep horizontal displacement monitoring is the monitoring link that is indispensable. The existing monitoring mode mainly adopts a sliding inclinometer or a pre-embedded deep horizontal displacement measuring unit for monitoring. Both have certain drawbacks. The sliding inclinometer needs to embed an inclinometer tube in advance, but the inclinometer tube is often twisted when embedded, so that later-stage monitoring data is inaccurate. Meanwhile, when the sliding inclinometer is used every time, a plurality of people are required to cooperate to place the inclinometer into an inclinometer pipeline, data are recorded at intervals during the falling process of the sliding inclinometer, and finally, the data are summarized to judge the displacement change. And another pre-embedded deep horizontal displacement measuring unit is a disposable product generally, so the use cost of the whole device is higher.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned defect of the prior art, the utility model aims at providing a universal joint survey pole to one side.
The purpose of the utility model is to realize through the following technical scheme:
the universal joint survey pole that inclines, including the sleeve pipe and arrange the intraductal connecting rod of sleeve in, the connecting rod is provided with two at least, every connect through universal joint between the connecting rod, every all set up measuring unit on the connecting rod.
Preferably, the measuring unit is disposed on the connecting rod through a connecting seat fixed to the connecting rod.
Preferably, the connecting rod is further provided with a centering ring, and the centering rings are arranged at two ends of the connecting rod.
Preferably, the connecting rod is disposed at an edge side of the righting ring.
Preferably, the adjacent measuring units are electrically connected through a connecting cable.
Preferably, the centering ring is provided with an exhaust hole, the aperture of the exhaust hole is larger than the diameter of the connecting cable, and the connecting cable is arranged in the exhaust hole in a penetrating manner and connected with the adjacent measuring units.
Preferably, the measuring units on the inclinometry rods are all arranged in the same direction.
Preferably, the sleeve is a rigid plastic tube.
Preferably, the outer diameter of the centralizing ring is comparable to the inner diameter of the casing.
The utility model discloses outstanding effect does: the utility model discloses a but the universal joint inclinometry pole has realized the deep horizontal displacement's of pre-buried formula recycle once more to can accomplish the deep horizontal displacement measuring unit's of pre-buried formula installation fast and bury underground.
The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The device comprises a connecting rod 1, a connecting base 2, a universal joint 3, a measuring unit 4, a connecting cable 5, a centering ring 6, an exhaust hole 61 and a sleeve 7.
Detailed Description
The utility model discloses a universal joint survey pole to one side combines fig. 1 to show, including sleeve pipe 7 and arrange connecting rod 1 in sleeve pipe 7 in, sleeve pipe 7 adopts the stereoplasm plastic tubing. The connecting rod 1 is provided with at least two. The specific number of the connecting rods 1 can be adjusted according to the needs, and in the embodiment, the connecting rods 1 are provided with 3 connecting rods. Every connect through universal joint 3 between the connecting rod 1, every all set up measuring unit 4 on the connecting rod 1. By changing the length of the connecting rod 1, the distance between the measuring units 4 and thus the measuring distance can be changed. The number of measurement units can also be varied as desired to accommodate wells of various depths. The measuring unit 4 is a horizontal displacement measuring unit, such as a horizontal displacement sensor, and the specific type and the like of the measuring unit are not limited.
Specifically, the connecting rod 1 is provided with a connecting base 2 for installing a measuring unit 4, and the measuring unit 4 is arranged on the connecting base 2. The adjacent measuring units 4 are electrically connected through a connecting cable 5. The universal joint 3 enables the inclination measuring rod to deform randomly along with the direction of the inclination measuring hole in the inclination measuring hole, so that better auxiliary measurement can be realized.
In order to ensure the position of the connecting rod 1 when the connecting rod enters the casing 7, the connecting rod 1 is provided with a centering ring 6, the outer diameter of the centering ring 6 is equivalent to the inner diameter of the casing 7, and the centering rings 6 are arranged at two ends of the connecting rod 1. Furthermore, the righting rings 6 are uniformly distributed on the connecting rod 1 of the inclinometer at intervals, are generally arranged at the head end and the tail end of the inclinometer, and are uniformly distributed at the middle section of the inclinometer. Meanwhile, in order to enable the inclination measuring rod to be more attached to the inclination measuring hole to deform, the connecting rod 1 is arranged on the edge side of the righting ring 6. The righting ring 6 is provided with an exhaust hole 61 to avoid gas resistance generated in the installation process. And the aperture of the exhaust hole 61 is larger than the diameter of the connecting cable 5, so that the connecting cable 5 can smoothly penetrate through the exhaust hole 61 to connect adjacent measuring units 4, and the space can be better saved. In order to better ensure the monitoring precision, the orientation of the measuring unit 4 on the inclined measuring rod is arranged in the same direction.
The following brief description of the utility model discloses a use installation:
during the use, with deviational survey connecting rod 1 with universal joint 3 interconnect, will complain measuring unit 4 and fix to deviational survey connecting rod 1 through connecting base 2 on, right circle 6 and install universal joint 3 below to respectively install a piece at whole root universal joint deviational survey pole lowermost part and the top right circle 6, connect connecting cable 5 well, and ensure that all measuring unit 4 are towards same direction, put into sleeve pipe 7 with the universal joint deviational survey pole that connects at last, the monitoring point is laid promptly and is accomplished. After the project is finished, the universal joint diagonal measuring rod and the measuring unit 4 in the sleeve 7 can be recovered, so that the monitoring cost is further reduced. The specific measurement and calculation method does not belong to the protection key of the present invention, and therefore is not repeated herein.
The utility model has a plurality of implementation modes, and all technical schemes formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
