Description

Technical Field

[0002] To shorten construction time and reduce the weight of bridges, prefabricated construction beams are widely used in bridge engineering. During the assembly and axis control process of construction beams at temporary sites, external environmental constraints pose significant challenges. The main factors include the steel plate material of the beam's top slab, making it difficult to mount a total station on its surface; the movement of personnel and repeated adjustments further complicate the process, making it difficult to maintain the stability of measuring instruments, thus affecting assembly accuracy and efficiency.

[0003] Due to the different shapes of bridges, there are several ways to splice adjacent construction beams. For example: Splicing Form 1: Adjacent construction beams are spliced ​​along a straight line, with the tops of the two beams coplanar and the beams being coaxial; Splicing Form 2: There is a longitudinal angle between the two construction beams, and their axes are coplanar; Splicing Form 3: There is a horizontal angle between the two construction beams, and their axes are coplanar. Determining the position of the construction beams for these splicing forms presents a significant challenge. Utility Model Content

This description is only a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.

[0035] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0036] In the initial embodiment, the present invention provides a pre-assembly axis control device for airport construction beams, such as... Figure 1-10 As shown, the project includes a first construction beam and a second construction beam to be assembled. The first construction beam is equipped with a first positioning mechanism at its top, and the second construction beam is equipped with a second positioning mechanism at its top.

The first positioning mechanism and the second positioning mechanism are equipped with mutually cooperating distance detection units and position detection units.

[0037] In splicing configuration one, the top axes of the first and second construction beams are not only coplanar but also collinear. In splicing configurations two and three, since there is a certain angle between the first and second construction beams, the top axes are coplanar and the angle between the top axes should meet the requirements.

[0038] In a further embodiment, such as Figure 1-10 As shown, the first positioning mechanism and the second positioning mechanism respectively include positioning plate 1 and positioning plate 2 (e.g., ...). Figure 1As shown), the positioning plate 1 and positioning plate 2 are respectively connected to the top steel plates of the first construction beam and the second construction beam via magnetic suction 5 (in this utility model, the tops of the first and second construction beams are flat by default; if the actual working conditions are uneven, they can be leveled, for example, by setting adjustable support legs on positioning plate 1 or positioning plate 2 to make them parallel to the preset horizontal plane at the top of the first or second construction beam).

[0039] In a further embodiment, such as Figure 1-10 As shown, the first positioning beam 101 and the second positioning beam 201 are provided with a plurality of through holes 17 along the centerline of the front-rear direction. When the center axis of the plurality of through holes 17 intersects with the top axis 4 of the corresponding first construction beam or the top axis 3 of the corresponding second construction beam, it means that the centerline of the first positioning beam 101 and the second positioning beam 201 along the front-rear direction is in the same longitudinal plane as the top axis 4 of the corresponding first construction beam or the top axis 3 of the corresponding second construction beam.

[0040] In a further embodiment, such as Figure 1-10 As shown, there are two linear drive mechanisms, respectively located on the top of the positioning plate 1 on the left and right sides of the first positioning beam 101 (e.g., Figure 1 As shown in the figure, the linear drive mechanism includes two first mounting plates 61 arranged opposite each other. A first lead screw 6 is rotatably connected between the two first mounting plates 61. The outer end of the first lead screw 6 passes through the corresponding first mounting plate 61 and is fixedly connected to the output shaft of a first servo motor (not marked in the figure) preset on the outer surface of the first mounting plate 61. A first movable seat (such as...) is screwed onto the first lead screw 6. Figure 2 As shown, the first movable seat 21) has a fixed block 22 on its top. The top of the fixed block 22 is connected to a first fixed plate 24 via a vertical rod 23. The front end of the first fixed plate 24 is provided with a transmitter 25.

[0041] In a further embodiment, such as Figure 1-10As shown, there are two coordinate positioning mechanisms, respectively located on the top of the positioning plates 2 on the left and right sides of the second positioning beam 201. Each coordinate positioning mechanism includes a second mounting plate (e.g., a second mounting plate arranged opposite to the left and right sides) Figure 1 , 4 As shown, there are two second mounting plates (A8 and B12). A second lead screw (not marked in the figure) is rotatably connected between the two second mounting plates. The outer end of the second lead screw passes through the corresponding second mounting plate and is fixedly connected to the output shaft of the second servo motor 15, which is preset on the outer surface of the second mounting plate. A second movable seat (such as...) is screwed onto the second lead screw. Figure 5 As shown, the second movable seat 21 has an electric cylinder 30 on its top. The fixed end of the electric cylinder 30 is embedded in the top of the second movable seat, and the telescopic end extends longitudinally upward and is fixedly connected to a hinge seat 29. A motor seat 32 is rotatably connected to the hinge seat 29 through a hinge shaft. One end of the hinge shaft is fixedly connected to the output shaft of a third servo motor 31 fixedly connected to the outside of the hinge seat 29. A fourth servo motor (such as...) is fixedly mounted on the top of the motor seat 32. Figure 8 As shown in the figure (not marked), the top of the output shaft of the fourth servo motor is provided with a second fixing plate 33, and the front end of the second fixing plate 33 is provided with a receiving end 34.

[0042] The bottom ends of the two second mounting plates are respectively connected by sliders to a first linear guide rail 7 and a second linear guide rail 9 arranged in the front-back direction. The first linear guide rail 7 and the second linear guide rail 9 are respectively fixedly connected to the top end of the positioning plate 2. A third lead screw 13 is also provided between the first linear guide rail 7 and the second linear guide rail 9 in the front-back direction. The two ends of the third lead screw 13 are respectively rotatably connected to a third mounting plate (such as...). Figure 4 As shown in the figure (not marked), the bottom end of the third mounting plate is fixedly connected to the top end of the positioning plate 2, and the outer side of the third mounting plate is provided with a fifth servo motor 14. The output shaft of the fifth servo motor 14 is fixedly connected to the end of the third lead screw.

[0043] A third movable seat 11 is screwed onto the third lead screw, and a crossbar 10 is connected between the two second mounting plates. The top end of the third movable seat 11 is fixedly connected to the bottom end of the crossbar 10. The second movable seat can avoid flipping by sliding with the crossbar, the first movable seat is connected to the top of the first positioning plate by sliding, and the bottom end of the third movable seat is slidably connected to the top of the second positioning plate.

[0044] The mechanism of coordinate positioning is:

[0045] The position of the third moving base in the X-axis can be controlled by the fifth servo motor 14, the position of the second moving base in the Y-axis can be controlled by the second servo motor 15, the height of the receiving end can be controlled by the electric cylinder, the elevation angle of the receiving end can be controlled by the third servo motor, and the horizontal rotation angle of the receiving end can be controlled by the fourth servo motor, thereby comprehensively controlling the XY axis coordinates and angles of the receiving end.

[0046] In a further embodiment, such as Figure 1-10 As shown, the controller is equipped with a database, which is based on data collected when the first construction beam and the second construction beam reach the docking position, including: (1) a data unit showing the one-to-one correspondence between the detection values ​​of the laser ranging sensor and the included angle, wherein the included angle refers to the included angle between the first construction beam and the second construction beam along the longitudinal direction and the included angle along the horizontal direction; such as Figure 1 , 6 As shown in Figures 7 and 9, during the docking process, the detection values ​​of the laser ranging sensor have a one-to-one correspondence with the included angle. Therefore, the correctness of the included angle can be verified by the detection values. (2) The corresponding data unit of the positional relationship between the transmitter and receiver and the included angle, that is, the position of the receiver in the coordinate positioning mechanism, the position of the transmitter on the first lead screw, the extension of the electric cylinder, the rotation angle of the third servo motor, and the rotation angle of the fourth servo motor at a certain included angle. For detailed application of this embodiment, please refer to the embodiments in the following content.

[0047] In a further embodiment, such as Figure 10 As shown, the bottom of the first and second construction beams are respectively equipped with jacking mechanisms A and B, which are electrically connected to the controller; the tops of the first and second positioning plates are respectively equipped with tilt sensors, which are electrically connected to the controller. The jacking mechanisms generally employ a DX jacking machine, which can achieve multi-directional adjustment of the construction beams.

[0048] In a further embodiment, such as Figure 10 As shown, a control method for an airport construction beam pre-assembly axis control device includes steps for splicing mode one, steps for splicing mode two, and steps for splicing mode three.

[0049] like Figure 1 , 6 As shown, the steps for splicing configuration one include:

[0050] S11. Install a first positioning mechanism at the top of the first construction beam and a second positioning mechanism at the top of the second construction beam, so that positioning plate one and positioning plate two are fixed to the top steel plate of the first construction beam or the second construction beam respectively by magnetic attraction; set the front-back direction as the X-axis and the left-right direction as the Y-axis, so that the transmitter and receiver on the left and right sides are at the same coordinate on the Y-axis, and the height of the transmitter and receiver are matched and cooperate with each other.

[0051] S12. Using jacking mechanisms A and B, the front ends of the first and second construction beams are aligned. After the top of the second construction beam is leveled, it remains stationary. Using jacking mechanism A, the top of the first construction beam is adjusted to be horizontal, and the laser rangefinder projects the horizontally emitted measuring light onto the front surface of the detection plate 16. When the detected distance is greater than the set distance, the first construction beam is moved to one side of the second construction beam until the laser rangefinder detects the set distance and stops. At this time, the controller determines that the distance between the first and second construction beams has reached the set requirement, and the included angle between the tops of the first and second construction beams is 180°.

[0052] S13. Move the first construction beam horizontally left and right to check if the transmitter and receiver on the left and right sides are aligned. If they are aligned, stop moving the first construction beam. If the signal from the receiver cannot be received after moving the first construction beam horizontally left and right a set distance, move the first construction beam upwards to a set height and repeat the left and right movement of the first construction beam until the transmitter and receiver on the left and right sides are aligned. At this time, the controller determines that the tops of the first construction beam and the second construction beam are coplanar, which also means that the top axes of the first construction beam and the second construction beam are coplanar. Based on the included angle of 180° between the tops of the first construction beam and the second construction beam and the coplanarity of the top axes of the first construction beam and the second construction beam, combined with the fact that the distance between the first construction beam and the second construction beam meets the set requirements, the controller determines that the first construction beam and the second construction beam have reached the docking position.

[0053] like Figure 7 As shown, the steps for splicing configuration two include:

[0054] S21. Based on the completion of step 13, the controller, according to the preset longitudinal angle between the top ends of the first construction beam and the second construction beam, uses the jacking mechanism A to tilt the rear end of the first construction beam upward and make the top end of the first construction beam reach the preset longitudinal angle between the top end of the second construction beam and the top end of the second construction beam.

[0055] S22, the jacking mechanism A controls the first construction beam to move up and down in conjunction with its forward and backward movement, until the laser rangefinder detects the detection value corresponding to the longitudinal angle in S21, and stops when the detection value remains unchanged during the forward and backward movement of the first construction beam (e.g., ...). Figure 7As shown, at this time, the measuring light 35 of the laser rangefinder 28 is projected onto the upper end of the second positioning beam (the measured value remains unchanged when the beam is moved back and forth); at this time, the initial correction of the influence of step S21 on the position of the first construction beam is completed, and the controller determines that the front top edges of the first and second construction beams are coplanar, and the longitudinal angle between the tops of the first and second construction beams reaches the set standard; however, on the other hand, the distance between the first and second construction beams in the front and rear directions still needs to be adjusted.

[0056] S23. The controller rotates the third servo motor clockwise by the same angle as in S21, and adjusts the extension / retraction of the electric cylinder and the position of the receiver in the coordinate positioning mechanism based on the database data. If the position of the transmitter on the first lead screw remains unchanged, only the position of the receiver in the X-axis is adjusted; if the position of the transmitter on the first lead screw changes, the Y-axis coordinates of the receiver and transmitter are adjusted to be consistent. Figure 7 As shown, the light emitted by the transmitter has an inclined angle, so the elevation angle, height, and coordinate position of the receiver need to be adjusted. Since the light emitted by the transmitter is parallel to the top of the positioning plate, the controller adjusts it according to the data in the database so that when the two sets of transmitters and receivers are triggered, it can determine that the top axes of the first and second construction beams are coplanar (the transmitters and receivers on both sides are aligned, so naturally the two top axes are in the same longitudinal plane. However, at the same time, the triggering of the transmitter and receiver also means that the distance between the first and second construction beams has reached the set standard, because the data in the database is collected when the docking position is reached).

[0057] S24. The jacking mechanism A controls the first construction beam to move back and forth, and detects whether the transmitter and receiver on the left and right sides are aligned. If they are aligned, the first construction beam stops moving. At this time, the controller determines that the top axes of the first construction beam and the second construction beam are coplanar and the distance between the first construction beam and the second construction beam reaches the set standard. The first construction beam and the second construction beam reach the docking position.

[0058] like Figure 9 As shown, the steps for splicing configuration three include:

[0059] S31. Based on the completion of step 13, the controller, according to the preset horizontal angle between the top of the first construction beam and the top of the second construction beam, uses the jacking mechanism A to rotate the first construction beam around one side of the front end, and makes the top of the first construction beam reach the preset horizontal angle between the top of the first construction beam and the top of the second construction beam.

[0060] S32. Keep the top of the first construction beam at the preset horizontal angle with the top of the second construction beam unchanged, and move the first construction beam back and forth and left and right until the detection value of the laser range sensor is consistent with the preset standard value and the detection value remains unchanged when moving the first construction beam left and right (at this time, the measuring light 35 moves left and right on the detection plate, so the measurement value remains unchanged). At this time, the controller determines that the distance between the first construction beam and the second construction beam in the front and back direction has reached the set requirement.

[0061] S33. Based on the horizontal angle in S31, the controller adjusts the transmitter on the first lead screw to reach the set position. Figure 9 Only the position adjustment of one side of the transmitter is given. In actual implementation, the positions of both sides of the transmitter need to be adjusted. Adjust the position of the receiver in the coordinate positioning mechanism and adjust the rotation angle of the fourth servo motor so that the receiver reaches the set angle (i.e. the angle that can cooperate with the transmitter when in the docking position).

[0062] S34. The jacking mechanism A moves the first construction beam left and right. It stops when the transmitting end and the receiving end are aligned. If no signal is detected after moving a certain distance, the first construction beam moves upward a certain distance and then moves left and right until the transmitting end triggers the receiving end. At this time, the controller determines that the top axes of the first construction beam and the second construction beam are coplanar. At the same time, the top ends of the first construction beam and the second construction beam are coplanar, and the first construction beam and the second construction beam reach the docking position.

[0063] In the above embodiments, once the docking position is reached, the connection between the first construction beam and the second construction beam can begin, such as welding or installing components like bolts.

[0064] This invention uses data collected after the docking position is completed to infer whether the first and second construction beams have reached the docking position through the control of the controller. Based on the detection data of the laser rangefinder and the cooperation of the transmitter and receiver of the through-beam photoelectric sensor, the relative position of the first and second construction beams is comprehensively judged, which can realize automated position adjustment, greatly reduce the difficulty of operation, and improve docking efficiency.
