The upright 5 is provided with a first drive assembly which drives the mounting plate 10 to slide along the mounting groove 8. The first drive assembly comprises a first motor 7 and a lead screw 14. The screw rod 14 is vertically and rotatably arranged in the mounting groove 8, and the mounting plate 10 is in threaded connection with the screw rod 14. The first motor 7 is fixedly arranged on the upper end face of the upright post 5, the motor shaft of the first motor 7 is vertically downward, and the motor shaft of the first motor 7 passes through the top wall of the mounting groove 8 and is coaxially and fixedly connected with the screw rod 14.
A pull rod 15 is fixedly connected to the lower end face of the mounting plate 10, the pull rod 15 is vertically arranged, and the lower end of the pull rod 15 is flexibly connected with the center of the upper end of the leveling rod 13 through a flexible rope. The leveling rod 13 is suspended below the mounting plate 10 by a pull rod 15. So that the leveling rod 13 can be freely adjusted according to the gravity of the leveling rod 13, and the leveling rod 13 is in a vertical state.
The lower end surface of the mounting plate 10 is rotatably provided with a second gear 17, and the limiting ring 12 is arranged on the lower end surface of the second gear 17 in a vertical moving way. The middle of the second gear 17 is coaxially provided with a perforation, and the upper end of the pull rod 15 passes through the perforation to be fixedly connected with the mounting plate 10. The limiting ring 12 is opposite to the upper end face of the leveling rod 13, and the projection of the limiting ring 12 on the upper end face of the leveling rod 13 falls into the upper end face of the leveling rod 13. The limiting ring 12, the pull rod 15 and the second gear 17 are coaxial.

The telescopic members comprise a first telescopic rod 6 and a second telescopic rod 11, and the first telescopic rod 6 and the second telescopic rod 11 are arranged in a staggered mode. The second telescopic rod 11 is an electric telescopic rod. In this embodiment, the first telescopic link 6 and the second telescopic link 11 are two.
The lower end of the limiting ring 12 is provided with a plurality of rolling grooves which are uniformly distributed along the circumference of the axis of the limiting ring 12, and each rolling groove is internally and rollably connected with a ball 18.
When the leveling rod 13 is adjusted in place, the leveling rod 13 swings under the action of self gravity and inertia. The stop collar 12 is moved downwardly in the direction shown in fig. 10, assuming that the balls 18 will contact the leveling rod 13 during the leftward swing of the leveling rod 13. The upper end surface of the leveling rod 13 is in an inclined state, so that the leftmost ball 18 is firstly contacted with the upper end surface of the leveling rod 13, and the ball 18 applies a vertical downward force to the leveling rod 13, so that the leveling rod 13 is prevented from continuously swinging leftwards, the swinging amplitude of the leveling rod 13 is reduced, and the leveling rod 13 moves to a horizontal state.
If the downward moving speed of the stop collar 12 is such that the leveling rod 13 gradually changes to the horizontal state, the leftmost ball 18 always keeps in contact with the leveling rod 13, and the leftmost ball 18 rolls on the upper end surface of the leveling rod 13. The balls 18 gradually come into contact with the leveling rod 13 from left to right. When the leveling rod 13 moves to a horizontal state, the plurality of balls 18 on the lower end surface of the limiting ring 12 are in contact with the leveling rod 13, and then the leveling rod 13 stops swinging under the action of the balls 18, so that the leveling rod 13 is stable in a vertical state.
If the downward moving speed of the stop collar 12 makes the leveling rod 13 gradually change to the horizontal state, the leftmost ball 18 is separated from the leveling rod 13, and when the leveling rod 13 swings rightward, the rightmost ball 18 contacts with the leveling rod 13 first, and the swing amplitude of the leveling rod 13 is further reduced because the stop collar 12 descends by a certain distance. Accordingly, the swing amplitude of the leveling rod 13 gradually decreases until the leveling rod 13 is in a vertical state, and the plurality of balls 18 are in contact with the leveling rod 13, so that the leveling rod 13 is stably maintained in a vertical state by the plurality of balls 18.
A limiting component is arranged in the limiting ring 12, and acts with the balls 18 to fix the balls 18.
The limiting component comprises a magnetic connecting block 20, a spring 21, an electromagnet 22 and a friction block 23.
A groove 19 is formed in the top wall of each rolling groove. The inner diameter of the groove 19 is smaller than the inner diameter of the rolling groove. One end of the spring 21 is fixed to the top wall of the groove 19, the other end of the spring 21 is vertically downward, and the magnetic connection block 20 is fixed to the lower end of the spring 21. A friction block 23 is fixed to the lower end of the magnetic connection block 20, and the friction block 23 is engaged with the balls 18. Electromagnet 22 is fixed on the top wall of groove 19, and electromagnet 22 is opposite to magnetic connection block 20 from top to bottom. When electromagnet 22 is energized, electromagnet 22 has a repulsive force against magnetic connection block 20.
When the electromagnet 22 is in the power-off state, under the action of the spring 21, a space is provided between the friction block 23 and the ball 18. When the electromagnet 22 is energized, the electromagnet 22 generates a repulsive force to the magnetic connection block 20, so that the magnetic connection block 20 moves downward against the elastic force of the spring 21, the friction block 23 contacts with the ball 18 and presses the ball 18, the ball 18 is fixed relative to the rolling groove, and the friction force between the limit ring 12 and the leveling rod 13 is increased. The second driving assembly is started, the second driving assembly drives the limiting ring 12 to rotate, and the limiting ring 12 drives the leveling rod 13 to rotate through the ball 18, so that the purpose of adjusting the angle of the leveling rod 13 is achieved.
The mounting plate 10 is provided with a second driving assembly, and the second driving assembly drives the limiting ring 12 to rotate through a second gear 17.
The second drive assembly comprises a second motor 9, a first gear 16. The second motor 9 is fixedly arranged at the upper end of the mounting plate 10, a motor shaft of the second motor 9 vertically penetrates through the lower end face of the mounting plate 10 downwards and then is fixedly connected with the first gear 16 in a coaxial mode, and the first gear 16 is meshed with the second gear 17. The second motor 9 drives the limiting ring 12 to rotate through the first gear 16, the second gear 17 and the telescopic piece.
Working principle: initially, the second telescopic rod 11 is in a contracted state, and a space is reserved between the limiting ring 12 and the leveling rod 13. Electromagnet 22 is in the de-energized state, and friction block 23 is spaced from ball 18 by spring 21.
Firstly, establishing a reference datum point on a highway foundation, knowing the elevation value of the reference datum point, assuming that the elevation value of the reference datum point is H, then vertically setting a reference leveling rod at the reference datum point, then reading an indication on the reference leveling rod through a leveling instrument, and assuming that the indication is L1, wherein the elevation value of an observation angle is H1 = H+L1.
And then the first supporting leg 2 and the second supporting leg 4 are pricked at the position of the settlement observation point, the second supporting leg 4 is rotated, and the leveling of the bottom plate 1 by the horizontal bubble instrument 3 is observed. And the influence of inclination on the angle of the leveling rod 13 on the detection result in the detection process is avoided.
Then, the first motor 7 is started, the screw rod 14 is rotated, the mounting plate 10 is moved up and down, the mounting plate 10 drives the leveling rod 13 to move up and down, the height of the leveling rod 13 is adjusted, and the first motor 7 is stopped after the adjustment is completed.
At this time, the leveling rod 13 swings under the action of its own weight and inertia. In order to quickly stabilize the leveling rod 13, the second telescopic rod 11 is started, so that the second telescopic rod 11 is extended, and the second telescopic rod 11 pushes the limiting ring 12 to move downwards.
As shown in fig. 10, the upper end surface of the leveling rod 13 is inclined while the leveling rod 13 swings leftward. Then the ball 18 at the leftmost end is firstly contacted with the upper end surface of the leveling rod 13, and the ball 18 applies vertical downward force to the leveling rod 13, so that the leveling rod 13 is prevented from continuing to swing leftwards, and the swing amplitude of the leveling rod 13 is reduced. Then, the leveling rod 13 swings downward, and the leveling rod 13 changes to a horizontal state.
If the downward moving speed of the stop collar 12 is such that the leveling rod 13 gradually changes to the horizontal state, the leftmost ball 18 always keeps in contact with the leveling rod 13, and the leftmost ball 18 rolls on the upper end surface of the leveling rod 13. The balls 18 gradually come into contact with the leveling rod 13 from left to right. When the leveling rod 13 moves to a horizontal state, the plurality of balls 18 on the lower end surface of the limiting ring 12 are in contact with the leveling rod 13, and then the leveling rod 13 stops swinging under the action of the balls 18, so that the leveling rod 13 is stable in a vertical state.
If the downward moving speed of the stop collar 12 makes the leveling rod 13 gradually change to the horizontal state, the leftmost ball 18 is separated from the leveling rod 13, and when the leveling rod 13 swings rightward, the rightmost ball 18 contacts with the leveling rod 13 first, and the swing amplitude of the leveling rod 13 is further reduced because the stop collar 12 descends by a certain distance. Accordingly, the swing amplitude of the leveling rod 13 gradually decreases, the leveling rod 13 is in a vertical state, the plurality of balls 18 are in contact with the leveling rod 13, the balls 18 have extrusion force on the leveling rod 13, and the leveling rod 13 is stably kept in the vertical state under the limiting action of the plurality of balls 18.
The reading of the levelling rod 13 is then observed by a level gauge and is noted as L2. The elevation value H2 = H+L1-L2 of the sedimentation point can be obtained according to H2 and H1.
When the scale direction and the observation angle in which the leveling rod 13 is stabilized are deflected, the observation is not facilitated. When the electromagnet 22 is energized, the electromagnet 22 generates a repulsive force to the magnetic connection block 20, so that the magnetic connection block 20 moves downward against the elastic force of the spring 21, the friction block 23 contacts with the balls 18 and presses the balls 18, and the balls 18 are fixed relative to the rolling grooves. So that the friction force between the ball 18 and the limit ring 12 is increased, and the limit ring 12 can drive the leveling rod 13 to rotate. The second motor 9 is started, the second motor 9 drives the limiting ring 12 to rotate through the first gear 16, the second gear 17 and the telescopic piece, and the limiting ring 12 drives the leveling rod 13 to rotate, so that the scale mark of the leveling rod 13 is gradually opposite to the observation angle, and the observation is convenient.
