Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Referring to fig. 1, the utility model provides a full sleeve pipe secant pile pore-forming vertical deviation monitoring structure can obtain the angle of slope so that correct, has characteristics such as easy to use, precision height. The following description is provided with reference to the accompanying drawings for the vertical deviation monitoring structure of the full-casing secant pile pore-forming.
As shown in fig. 1 and 2, the utility model discloses full sleeve pipe secant pile pore-forming vertical deviation monitoring structure includes: the bubble vial comprises a sleeve 10 detachably hooped on a sleeve 90, a level bubble 13 arranged on the upper surface of the sleeve 10, a sensor 21 fixed on the sleeve, a controller 22 electrically connected with the sensor, an alarm 23 and a display 24 electrically connected with the controller 22.
As shown in fig. 1, the sleeve 10 includes an upper ring 101, a lower ring 103 below the upper ring, and a connecting cylinder 102 connecting the upper ring and the lower ring. Wherein the upper ring 101 and the lower ring 103 are both flat annular pieces and are perpendicular to the axis of the bushing 90 such that the upper surface of the sleeve is perpendicular to the axis of the bushing. The connector barrel 102 is of a cylindrical configuration and has an inner wall which abuts the outer wall of the sleeve 90 so that the axis of the sleeve 10 is coincident with the axis of the sleeve 90 and the sleeve 10 tilts as the sleeve 90 tilts. Preferably, the sleeve 10 comprises two openable semicircular structures, one side of the two semicircular structures is connected by a hinge 11, the other side of the two semicircular structures is provided with a buckle 12, the two buckles 12 on the two semicircular structures are buckled to tightly clamp the sleeve 10 on the sleeve 90, and conversely, the sleeve 10 can be detached by releasing the buckle 12.
The level vial 13 is disposed on the upper surface of the sleeve 10, i.e., the upper surface of the upper ring 101. In a preferred embodiment, the vials 13 include two vials 131, the vials 131 are disposed perpendicular to each other, and the vials 131 are both disposed along a tangent of the upper ring 101. It should be noted that the arrangement of the vials is not limited to the above-described embodiment, and the number of vials may be plural and may be arranged in the radial direction of the upper ring 101. Further, vial 13 includes a circular vial that more intuitively reflects the vertical deviation of cannula 90 and the direction of its inclination. By adjusting the sleeves 90 so that the bubbles in a plurality of vials are all centered within the vial, the sleeve 10 and sleeves 90 are both in an initial vertical position.
As shown in fig. 2, the sensor 21 is fixed on the sleeve 10, the voltage signal output by the sensor 21 when the sleeve 10 and the casing 10 are in the initial vertical position is the initial voltage signal, and the voltage signal output by the sensor 21 changes with the inclination of the sleeve and the casing.
In one embodiment, the sensor is an accelerometer 211, and the accelerometer 211 is a sensor capable of measuring acceleration, and since only gravity acts during construction, the accelerometer 211 monitors that the force direction changes and outputs a corresponding voltage signal during the gradual tilting of the casing 90 from the initial vertical state.
In another embodiment, the sensor is a gyroscope 212, the gyroscope 212 is a sensor capable of measuring an angular velocity, and in the process that the casing 90 is gradually inclined from the initial vertical state, the gyroscope 212 obtains an angular velocity value and outputs a corresponding voltage signal, and the obtained angular velocity value is integrated to obtain the inclination angle.
In yet another embodiment, the sensor is a device that integrates an accelerometer 211 with a gyroscope 212. Since the accelerometer 211 is easily affected by vibration, the noise in the signal is large, while the gyroscope is less affected by vibration and can smooth the signal, but since an integration operation is required, if the angular velocity signal has a slight deviation, the angular velocity signal changes after the integration operation to form an accumulated error, and the accumulated error increases gradually with the time, and finally the circuit is saturated, and a correct angle signal cannot be formed. Therefore, the device integrating the accelerometer 211 and the gyroscope 212 is used as a sensor, and the signals of the accelerometer 211 and the gyroscope 212 can be mutually corrected to obtain more accurate output, so that the precision of the monitoring structure is improved.
Specifically, angle information theta g obtained by the accelerometer is compared with an angle theta obtained after the gyroscope is integrated, and the compared error signal is amplified by the proportion of 1/Tg and then is superposed with an angular velocity signal output by the gyroscope, and then is integrated. For the given angle theta g of the accelerometer, the angle theta generated after proportional and integral links is necessarily equal to theta g finally.
The output angle comprises two first-order inertia links, wherein the first term is an angle corresponding to a gravity acceleration Z axis, and the second term is a numerical value of the acceleration of the gyroscope passing through the inertia links. The system has no pure integral link, so the micro deviation of the angular speed of the gyroscope can not form accumulated errors. Where the parameter Tg determines the time constant of these two inertial elements. T g, the larger the angle output tracks the Z-axis output, but the more noise Tg on the gravity accelerometer is effectively suppressed, which amplifies the gyroscope output error.
In order to avoid too long tracking time of the output angle theta, the following two measures can be taken:
(1) the amplification circuit of the gyroscope is carefully tuned so that its zero point bias is as close as possible to the set point and is stable.
(2) At the beginning of the operation of the control circuit and the program, the object is kept as much as possible in the set state, so that the output angles θ and θ g are made equal at the beginning. Thereafter, the output of the accelerometer simply cancels the deviation of the integral, and the output angle does not have large deviation.
The controller 22 is electrically connected to the sensor, and the controller 22 collects a voltage signal output by the sensor and converts the collected voltage signal into a corresponding tilt angle value. A display 24 is electrically connected to the controller 22 for displaying the tilt angle value so that the builder can visually see the vertical deviation of the sleeve.
The alarm 23 is electrically connected to the controller 22, a monitoring unit is arranged in the controller 22, the monitoring unit compares the inclination angle value with a set angle value, and when the inclination angle value is larger than the set angle value, the controller 22 controls the alarm 23 to give an alarm, so that the constructor can correct the direction of the sleeve in time.
It is following right the utility model discloses the construction and the use of full sleeve pipe secant pile pore-forming vertical deviation monitoring structure explain.
The two semicircular structures of the sleeve are firstly opened through the hinge piece, the sleeve is hooped on the sleeve, and then the buckle is buckled to fix the sleeve on the sleeve. The straightness that hangs down of adjustment sleeve pipe makes the bubble in the air level be located the central point of air level to zero the sensor at this moment, can carry out the construction afterwards, constructor accessible display observes the angle of sleeve pipe slope directly perceivedly in the work progress, and if sleeve pipe inclination surpasss the angle of settlement then the siren sends out the police dispatch newspaper in the work progress.
The present invention has been described in detail with reference to the embodiments shown in the drawings, and those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details of the embodiments should not be construed as limitations of the invention, which are intended to be covered by the following claims.
