DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "center, lateral, longitudinal, up, down, front, back, left, right, vertical, horizontal, top, bottom, inside, outside" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] The technical solution of the present invention is a horizontal stabilization device for an observer, and its three-dimensional structural schematic diagram is shown as follows: Figure 1 , its front view is as follows Figure 2 As shown, its cross-sectional structural diagram is as follows Figure 3 As shown, the base 1 includes at least three support members 2 evenly arranged in a ring. The upper end of the support member 2 is connected to a support ring 3. The center line of the support ring 3 is perpendicular to the ground plane of the base 1. The upper part of the support ring 3 is a concave annular spherical surface 301. A ball seat 4 is provided in conjunction with the annular spherical surface 301. The upper surface of the ball seat 4 is horizontal. A tie rod 5 is provided at the bottom center of the ball seat 4. The tie rod 5 passes through the support ring 3 and is connected to a foundation block 6, and the foundation block 6 is suspended in the air.

[0032] By the corresponding matching arrangement of the supporting ring 3 and the spherical seat 4, the spherical seat 4 can also maintain a horizontal state when the terrain is slightly inclined, thereby providing a stable and reliable observation platform for the observer.

[0033] When the abutment or bridge deck is impacted by waves or rivers under surge conditions, it will sway slightly, and the suspended foundation block 6 will increase the gravity of the spherical seat 4, so that the tie rod 5 will be perpendicular to the horizontal plane. When installing the horizontal stabilization device, the tie rod 5 is connected to the spherical seat 4, penetrates the support ring 3, and the tie rod 5 is screwed to the foundation block 6 to facilitate the installation of the tie rod 5 and the foundation block 6. The tie rod 5 can be a steel bar, a steel bar, or other soft or wooden bars.

[0034] The accuracy of the concave annular spherical surface 301 and the spherical surface of the ball seat 4 will affect the observation reliability of the observer. In mechanical manufacturing, the annular spherical surface 301 and the spherical surface of the ball seat 4 have high accuracy requirements, and lubricating parts are filled between them. The lubricating parts can be ordinary lubricating oil, fine butter or lubricating plastic, etc., to reduce the friction between the annular spherical surface 301 and the spherical surface of the ball seat 4. When the terrain is slightly tilted, the ball seat 4 can also maintain a horizontal state, thereby providing a stable and reliable observation platform for the observer 16.

[0035] In order to reserve more sufficient activity space for the basic block 6, the upper center of the base 1 is set as a concave surface, and the concave surface can be a semicircular concave or a rectangular concave.

[0036] One fifth of the volume of the sphere is beneficial to the stable movement of the ball seat 4 on the supporting ring 3 without slipping off, so the ball seat 4 is set to one fifth of the volume of the sphere.

[0037] In order to prevent the horizontal stabilization device from tilting significantly, a positioning buckle is provided on the horizontal plane of the ball seat 4 for buckling the observer 16. The positioning buckle can be a slot, a spring clip or a positioning bandage. The observer 16 can be any instrument required for observation, such as a level, a level meter, etc.

[0038] If the abutment or pier sways slightly under surge conditions, as long as it does not affect its safety performance within a certain normal range, construction can continue on its basis. However, if the sway exceeds a certain range, the abutment or pier is no longer suitable for continued construction. The structure is enlarged in the A direction as shown in the figure below: Figure 4 As shown, in order to clearly read the shaking value, the basic block 6 is evenly connected to the basic rod 7, the position of the basic rod 7 corresponds to the position of the support member 2, the outer end of the basic rod 7 passes through the support member 2 and is provided with a positioning piece 8, a first spring 9 is provided between the positioning piece 8 and the support member 2, and a scale 10 is provided at the lower part of the support member 2, and the scale 10 is located below the positioning piece 8.

[0039] By setting a basic rod 7 on the basic block 6 and a scale 10 below the basic rod 7, when the base surface is tilted, the horizontal stable structure tilts, and the ball seat 4 is relatively horizontal, that is, the basic block 6 is relatively horizontal, thereby driving the basic rod 7 to move relative to the support member 2. The movement amount is read by the scale 10 to determine whether the base surface tilt exceeds the range, that is, to determine the impact state environment of the abutment or bridge deck, etc. The reading is marked on the scale 10 according to the change amount.

[0040] In order to accurately judge the details of the shaking, multiple support members 2 can be evenly arranged, preferably an even number, four or eight are appropriate numbers, and values ​​are read in all directions. Preferably, when the device is level as a whole, the positioning piece 8 is located at the zero scale of the scale 10, the outer side of the positioning piece 8 can be a positive value, and the inner side of the positioning piece 8 can be a negative value. When the abutment or pier is slightly tilted, the sum of the scales of the relative positioning pieces 8 is zero, and the value with the largest scale change is read to determine whether the shaking amount exceeds the range, and the shaking direction is determined by determining which scale value has the largest value.

[0041] The first spring 9 only plays a buffering role to prevent the hard collision between the positioning piece 8 and the support member 2 from causing vibration and affecting the use of the horizontal stabilizer. The setting of the first spring 9 cannot affect the vertical effect of the base block 6 and the tie rod 5 relative to the horizontal plane.

[0042] The basic rod 7 passes through the support member 2, and its contact position is set to be smooth. The through hole can be relatively enlarged so that it does not affect the movement of the basic rod 7. It is best that when it is horizontal or shaking, the basic block 6 and the basic rod 7 are both suspended, so that the read value is accurate.

[0043] When the horizontal stabilizer is placed on a cap or a pier, if the cap or the pier shakes greatly, or the bottom of the horizontal stabilizer will have a hard impact with the base surface during transportation, in order to avoid the impact affecting the life of the horizontal stabilizer, a buffer structure is set at the bottom of the base 1, and a cross-sectional structural diagram of the buffer structure is added as shown in FIG. Figure 5 As shown, a plurality of fixing holes 11 are evenly arranged below the base 1, a mounting plate 12 is arranged at the bottom of the base 1, a fixing column 13 is arranged on the mounting plate 12 corresponding to the fixing hole 11, the fixing column 13 passes through the second spring 14, and the fixing column 13 passes through the fixing hole 11 and is connected to the fixing cap, and a plurality of mounting holes 15 are evenly arranged on the mounting plate 12.

[0044] The mounting hole 15 is used to fix the device on the abutment or bridge pier. The elastic deformation of this buffer structure is small, which plays a role of micro-buffering, so as to avoid the influence of the accuracy of the value of the scale 10 when the deformation of the buffer structure is large.

[0045] The surge conditions described in the present invention refer to the vibrations caused by the ups and downs of waves in the ocean or river. This vibration will have a great impact on the measuring equipment, resulting in a lack of a stable foundation during construction and measurement in the marine environment, causing the results measured by the measuring equipment to be inaccurate and unusable.

[0046] When the base 1 shakes slightly or violently in a surge environment, the center of gravity of the ball seat 4 is always vertically downward, and only the base 1 and the support 2 shake slightly, because the ball seat 4 and the support 2 below are in contact through a spherical surface, so the ball seat 4 has the principle of stability under its own gravity, and also ensures that the central axis of the level observer is always vertically downward. This is the stability principle of the level observer, and the reading of the level observer can be accurately measured through this principle.

[0047] The working process of the horizontal stabilizer is as follows:

[0048] First, install and debug the horizontal stabilization device; after the tie rod 5 passes through the supporting ring 3, it is screwed to the foundation block 6, and the foundation rod 7 passes through the through hole of the support member 2 and is screwed to the foundation block 6; debug the device, adjust the mounting plate 12 and the spherical seat 4, when it is horizontal, the foundation block 6 and the foundation rod 7 are in a suspended state, the center line of the spherical seat 4 is perpendicular to the horizontal plane, and the positioning piece 8 is on the zero scale of the scale 10.

[0049] Secondly, install the horizontal stabilizer; through the mounting hole of the mounting plate 12, install the horizontal stabilizer on the abutment or pier, fix the observer 16 through the positioning buckle, and adjust the mounting screws and the positioning buckle.

[0050] Again, observe and read the values; the observer 16 performs observation and reads the shaking values ​​of the abutment or pier at the same time. The values ​​read by the relatively positioned scales 10 must sum to zero. If the reading on one side is positive, it must be negative relative to the other side. By reading the maximum values ​​of several scales 10, the shaking direction and whether the shaking exceeds the range can be determined.

[0051] Finally, disassemble; after the observation and reading of the values ​​are completed, disassemble the horizontal stabilizer, remove the mounting screws, and slowly place the horizontal stabilizer into the transport box, keeping the box environment dry and avoiding excessive impact.

[0052] In summary, on the one hand, by the corresponding matching arrangement of the support ring 3 and the spherical seat 4, the spherical seat 4 can also maintain a horizontal state when the terrain is slightly tilted, thereby providing a stable and reliable observation platform for the observer; on the other hand, by arranging the basic rod 7 on the foundation block 6 and the scale 10 below the basic rod 7, when the base surface is tilted, the stable structure tilts, and the spherical seat 4 is relatively horizontal, that is, the foundation block 6 is relatively horizontal, thereby driving the basic rod 7 to move relative to the support 2, and the movement amount is read by the scale 10 to judge whether the base surface tilt exceeds the range, that is, to judge the impact state environment of the pedestal or bridge deck, etc. The problem mentioned in the prior art that the slight shaking of the offshore pedestal or bridge pier affects the accuracy of the observer 16, and the problem that the slight shaking of the pedestal or bridge pier exceeds the range affects the construction work and threatens its construction safety is solved.
