Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides a dismantled pillar offset monitoring device, comprising: a base 1 and a measuring mechanism; the measuring mechanism comprises a lifting block 8, an upper measuring rod 3 and a lower measuring rod 5 located just above the base 1, the upper measuring rod 3 is slidably installed on one side of the lifting block 8, an upper measuring head 4 is arranged at the end of the upper measuring rod 3, the lower measuring rod 5 is located on the base 1, a lower measuring head 6 is arranged at the end of the lower measuring rod 5, a displacement sensor 20 is installed on the upper measuring rod 3, a tape measure 7 is fixed to one side of the upper measuring head 4, and the end of the tape measure 7 is fixedly connected to one side of the lower measuring head 6; a first baffle 10 is arranged at the end of the upper measuring rod 3, one end of a rack 11 is fixedly connected to one side of the first baffle 10, and the other end of the rack 11 is fixedly connected to a second baffle 12.

[0027] A driving mechanism for driving the upper measuring head 4; the driving mechanism includes a rack 11, a driving gear 14 and a motor 13. A cavity 15 penetrating the lifting block 8 is provided on the lifting block 8. The rack 11 is located at one end of the upper measuring rod 3, and the rack 11 is slidably installed in the cavity 15. The driving gear 14 rotates inside the cavity 15, and the driving gear and the rack 11 are meshed. The driving gear is driven by the motor 13. A control panel 9 is installed on the outer wall of the lifting block 8. The motor 13 is fixedly installed on one side of the outer wall of the lifting block 8, and the output end of the motor 13 is transmission-connected to the driving gear 14.

[0028] Among them, a display screen and control buttons are set on the control panel 9 for controlling the cylinder 2 and the motor 13 and calculating the measurement results, and the displacement sensor 20 signal is connected to the control panel 9;

[0029] When the upper measuring head 4 is zeroed (i.e., when the first baffle 10 is attached to the side wall of the lifting block 8), the upper measuring head 4 is coaxially arranged with the lower measuring head 6, the length of the upper measuring rod 3 is the same as the length of the lower measuring rod 5, and a guide wheel is arranged at the outlet of the tape measure 7 so that the upper part of the tape measure is located at the lower end of the upper measuring head 4 during measurement, and the lower end of the tape measure is arranged on the lower end side of the lower measuring head 6 through a connecting rod;

[0030] When the first baffle 10 abuts against the lifting block 8, it is the zero point. At this time, if the upper and lower measuring heads 6 can abut against the pillar, the pillar is not tilted or offset;

[0031] When the second baffle 12 contacts the lifting block 8, the maximum measuring length is reached.

[0032] In actual use, the device is moved to a designated point. When measuring the pillar, the lower measuring head 6 is made to contact the pillar. At this time, the length of the tape measure 7 is a right-angled side of the right triangle. The motor 13 is started, and the motor 13 drives the driving gear 14 to rotate. Since the rack 11 and the driving gear 14 are meshed, the upper measuring head 4 can be displaced until the upper measuring head 4 contacts the pillar. At this time, the length of the tape measure 7 is the hypotenuse of the right triangle, and when the displacement sensor 20 is displaced with the upper measuring rod 3, the reading of the displacement sensor 20 is the displacement of the pillar, and the reading is the other right-angled side of the right triangle. According to the trigonometric function, the two acute angles of the right triangle can be calculated, so as to know the displacement angle of the pillar.

[0033] When calculating specifically: the measurement results give a right triangle, where the right angle is at point A, B and C are the other two points, AB is the right side, and AC is the hypotenuse.

[0034] Angle B (or Angle C, since they are both acute angles) can be calculated using the following formula:

[0035] tan(B)=AB / BC

[0036] tan is the tangent function, B is the angle to be calculated, AB is the length of the right angle side, and BC is the length of the other right angle side.

[0037] The control method of the control panel 9 of the present application is to use a built-in PLC controller. The control circuit of the PLC controller can be realized by simple programming by technicians in this field, which is common knowledge in this field. In addition, the present application document is mainly used to protect mechanical devices, so the present application document no longer explains the control method and circuit connection in detail. Through code programming by technicians in this field, numerical values ​​can be input and measurement results can be output through the control panel 9.

[0038] Also, see Figure 1 :

[0039] A slide groove 16 is provided at the bottom of the cavity 15 of the lifting block 8, and a slider 17 is integrally formed at the bottom of the rack 11, and the slider 17 is slidably installed inside the slide groove 16. A cylinder 2 is installed on the base 1, and the end of the telescopic rod of the cylinder 2 is fixedly connected to the bottom of the lifting block 8. Convex plates 18 are symmetrically provided on the outer walls on both sides of the upper end of the cylinder 2, and guide rods 19 are symmetrically provided at the bottom of the lifting block 8, and the guide rods 19 are slidably inserted into the convex plates 18.

[0040] The height of the upper measuring head 4 can be adjusted by the cylinder 2, so that it can be adapted to pillars of different heights, greatly improving the application range of the device.

[0041] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
