Description

Technical Field

[0001] The invention relates to the technical field of gate surveying and mapping, and in particular discloses a measuring device and a measuring method for gate slot installation. Background Art

[0002] The gate is an important part of hydraulic structures. During the installation of the gate, the quality of the gate slot installation directly affects the installation and water-blocking effect of the gate. The main control inspection items for the gate slot installation quality include: the deviation of the main rail surface, the water stop plate to the center of the gate slot, the center of the orifice, and the flatness of the working surface. In the NB / T35045 specification: the qualified standard for the deviation of the main rail slide surface of the gate slot and the water stop plate to the center of the gate slot is within the working range of -1 to +2mm, the qualified standard for the deviation to the center of the orifice is within the working range of -3 to +3mm, and the qualified standard for the deviation of the working surface flatness is ≯2mm; the distance between adjacent measuring points is ≯1m. Among these inspection items: the flatness of the main rail slide surface and the water stop plate surface is directly related to the water-sealing effect of the gate.

[0003] At present, in traditional inspection work, the inspection method for the above deviation is the vertical piano wire method, that is, a piano wire is hung at the top of the door slot, and a weight is hung at the bottom of the piano wire. After the piano wire is stable, the minimum distance between the piano wire and the measured surface of the door slot is measured with a steel ruler at every 1m interval from the top to the bottom of the door slot. After the measurement, the minimum distance of each measuring point is compared to see the verticality of the door slot installation and the flatness (straightness) of the measured surface. Combined with the large span (the distance between the main rails and the counter rails on the left and right sides) and the small span (the distance between the main rail and the counter rail on the same side) at the top or bottom of the door slot, the deviation of the main rail and the counter rail from the center of the door slot and the deviation from the center of the orifice can be determined. However, in water conservancy projects, the use of traditional inspection work has certain shortcomings. The following are some of the following problems: (1) The heights of gate slots such as diversion tunnels, dam center holes, and surface holes are all tens of meters. After the construction of the embedded parts of the gate slots is completed, a rack must be set up to assist in the acceptance. According to the specifications, the distance from the top to the bottom of the gate slot should be measured every 1m. Therefore, the construction rack construction workload is large, and the inspection personnel also face certain risks of working at heights; (2) During the measurement process, the piano wire is easily disturbed by external interference conditions (such as wind, accidental collision, etc.) and swings. At this time, it takes a long time to wait for the piano wire to stabilize, affecting the acceptance efficiency and measurement accuracy; (3) When reading the steel ruler, the human eye's estimation of the distance is also biased, which can easily cause measurement errors. Therefore, a measuring device and a measuring method for gate slot installation are proposed to improve the above problems. Summary of the invention

[0045] A measurement method for gate slot installation, referring to Fig.10 , applied to a measuring device for gate slot installation, comprising the following steps:

[0046] Step 1: Place the trolley on the surface to be measured, use the lifting assembly 4 to cooperate with the adsorption and adhesion assembly to adjust the gap between the magnet 2 and the surface to be measured, control the suction force of the magnet 2 to ensure that the rear wheel 3 and the directional front wheel 8 and the pulley 23 are in close contact with the surface to be measured, and control the trolley to automatically crawl along the vertical direction of the surface to be measured by the single-chip controller 18;

[0047] Step 2: Control the car to travel along the specified path through the second inclination sensor 25 and the single chip controller 18;

[0048] Step 3: Under the instruction of the single-chip controller 18, the trolley moves intermittently with a cycle of one wheelbase forward and a 5s pause, and records each pause point, i.e., A0-An, and the deviation of each pause point of the trolley passing through the measured surface is detected and recorded, and the flatness of the door slot installation can be calculated through mathematical calculation, and the display screen 7 is used to display the displacement value and flatness of each measuring point of the trolley;

[0049] Step 4: In the rectangular coordinate system, set the reference point. The X-axis represents the ideal plumb plane and the displacement of the measuring trolley. The Y-axis represents the offset between the measuring trolley and the ideal plumb surface. The curve represents the contour of the measured surface of the door slot. Point A0 represents the starting point of the measured surface, and point An represents the end point of the measured surface. Then, sort the verticality of the n points to obtain the maximum, minimum and position of the verticality of each point on the measured surface of the door slot.

[0050] In summary, the measuring principle of the present invention is as follows: when working, the inspector places the trolley on the surface to be measured, and uses the turntable 401 in the lifting assembly 4 to drive the main shaft 408 to rotate, and drives the two transmission belts 402 and the three double pulleys 409 and the two transmission rods 403 to rotate, and cooperates with the meshing action of the worm 406 and the worm wheel 405 to drive the lifting plate 410 and the magnet 2 in the adsorption and adhesion assembly to move, adjust the gap between the magnet 2 and the surface to be measured, and control the suction force of the magnet 2 to ensure that the rear wheel 3 and the directional front wheel 8 and the pulley 23 are in close contact with the surface to be measured in the door slot; then, the inspector controls the driver 9 and the directional front wheel 8 to work through the single-chip controller 18, and controls the trolley to automatically crawl along the vertical direction of the measured surface. When the entire measuring trolley does not travel along the specified path, it will generate a gap with the original path. Angle, at this time, the trolley detects this angle through the second inclination sensor 25, and after finding it, it sends a signal to the stepper motor to deflect an opposite angle, so as to ensure that the measuring trolley travels along the specified path; then, under the instruction of the single-chip controller 18, the trolley makes intermittent motion with a period of pausing for 5s every time it advances one wheelbase, and the pulley 23 and the feeler rod 20 move on the uneven measured surface, synchronously driving the first inclination sensor 13 to deflect. When the directional front wheel 8 of the trolley moves from point A0 (starting point) to point A1, the rear wheel 3 of the trolley arrives at point A0 synchronously. At this time, the trolley stops moving forward. After a stabilization time of 5s, the angle between the trolley body 1 and the X-axis is read as α1 through the first inclination sensor 13, and a perpendicular line through point A1 is drawn to the x-axis, and the intersection point with the x-axis is B1 (such as Fig.10 As shown), in the right triangle △A0A1B1, when α1 is very small, the value of A0A1×Sinα1 is basically consistent with the value of α1×π×AOA1 / 180 (arc length formula), so A1B1=α1×π×AOA1 / 180=3.49α1, where the value of line segment A1B1 represents the offset of point A1 relative to point A0 (starting point) in the Y direction (i.e., verticality); similarly, when the directional front wheel 8 moves from point A1 to point A2, the rear wheel 3 of the car reaches point A1, and the angle between the car and the X-axis is α2, and a perpendicular line through point A2 intersects with the x-axis at B2, and a line parallel to the x-axis through point A1 intersects with line segment A2B2 at C2 (as shown Fig.10As shown), in the right triangle △A1A2C2, A2C2=3.49α2, wherein the value of line segment A2C2 represents the verticality of point A2 relative to point A1 in the Y direction. The value of line segment A2C2 is algebraically added with the value of A1B1 to obtain A2B2, and the value of line segment A2B2 represents the verticality of point A2 relative to point A0 (starting point) in the Y direction. Similarly, as the trolley continues to move, the verticality of points A3, A4...An relative to point A0 (starting point) in the Y direction can be obtained. After that, the verticality of n points can be sorted, and the maximum value, minimum value and position of the verticality of each point on the measured surface of the door slot can be known, the flatness of the door slot installation can be calculated, and the displacement value and flatness of the trolley at each measuring point can be displayed on the display screen 7.

[0051] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
