Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a laser locator for a water steel casing guide frame device and a method thereof. Background Art

[0002] In the process of concrete pouring pile foundation construction of river-crossing bridges, in view of comprehensive considerations of environmental protection, construction quality, safety and economy, water-based steel casings are usually pre-installed before pile foundation construction. In order to ensure that the verticality of the water-based steel casing construction does not exceed one thousandth, and the pile center offset is not greater than 3 cm, in order to meet the subsequent water-based concrete pouring pile foundation operations, a special water-based steel casing construction guide device must be used.

[0003] The guide device is divided into two layers, the upper and lower layers of the construction bridge deck. The guide device on the bridge deck can be accurately positioned with the help of high-precision equipment such as GPS engineering surveying instruments and total stations. However, for the guide device under the bridge deck, due to space limitations and line of sight obstruction, the above instruments cannot be directly applied.

[0004] At present, when installing the guide device under the bridge deck, the plumb bob positioning method is adopted. The specific operation method is to set a number of plumb bobs on the guide device on the bridge deck, and install the guide device under the bridge deck according to the position of the plumb bobs. However, this method has many defects:

[0005] 1. Limited accuracy: In modern construction that pursues extremely high precision, the accuracy of the plumb bob orientation method often cannot meet the requirements, and its error range may exceed the threshold allowed by the construction.

[0006] 2. The operation is cumbersome and time-consuming: Plumb bob orientation requires manual operation, and the swing of the plumb bob must be observed at all times to determine the direction, which not only increases the complexity of the operation, but also prolongs the construction time and reduces efficiency.

[0007] 3. Susceptible to environmental factors: The plumb bob orientation method is easily affected by natural factors such as wind and vibration, causing the plumb bob to swing away from the true vertical direction, thus affecting the accuracy of the measurement results. Summary of the invention

[0008] The embodiment of the present invention provides a laser locator and method for an underwater steel casing guide frame device, which utilizes the characteristics of a laser beam to complete the orientation work. Compared with the existing positioning method using a plumb bob, it not only has less interference and can effectively improve the positioning accuracy, but also can be automatically operated, thereby improving the convenience of use.

[0009] In view of the above problems, the technical solution proposed by the present invention is:

[0011] A laser output component having at least one laser for outputting a laser beam;

[0012] The connection adjustment component is connected to the laser output component to connect the laser output component to the guide device; and to adjust the angle of the laser beam output by the laser output component.

[0018] Furthermore, a magnetic ring is provided on a side of the rotary driver a away from the mounting frame, and a signal output end of the control module is communicatively connected with the rotary driver a and a signal input end of the rotary driver a.

[0019] A positioning method for an above-water steel casing guide frame device comprises a control end and at least four laser output components, wherein the control end is in communication connection with the laser output components;

[0020] The following steps are involved:

[0021] Use positioning instruments to position the guide device on the deck of the temporary bridge under construction;

[0032] The control end controls the laser output component to change the parameters of the output laser beam according to a preset mode.

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Figure 2 A schematic diagram of the structure of a laser locator disclosed in an embodiment of the present invention is shown. The laser locator proposed in the present invention has four working modes.

[0048] Working mode 1: Single machine working mode 1.

[0049] In the above working mode, the laser output component 1 is turned on by pressing the button 12, and the connecting adjustment component 2 is magnetically attracted to the guide device 3. At this time, the control module 15 determines the level of the current laser output component 1 according to the signal output by the horizontal sensor 16 (when the laser output component 1 is horizontal, the laser beam output by it is perpendicular to the horizontal plane). When it is recognized that the position of the laser output component 1 is not horizontal, the control module 15 controls the rotation driver a22 and the rotation driver b23 to adjust the rotation angle according to the signal output by the horizontal sensor 16. When it is determined that the position of the laser output component 1 is horizontal according to the signal output by the horizontal sensor 16, the rotation driver a22 and the rotation driver b23 are controlled to stop running.

[0050] Working mode 2: Single machine working mode 2.

[0051] In the above working mode, the control module 15 obtains the signal output by the horizontal sensor 16 in real time to determine the current level of the laser output component 1. When it is identified that the position of the laser output component 1 is not horizontal, the control module 15 controls the rotation driver a22 and the rotation driver b23 to adjust the rotation angle according to the signal output by the horizontal sensor 16. When it is determined that the position of the laser output component 1 is horizontal according to the signal output by the horizontal sensor 16, the rotation driver a22 and the rotation driver b23 are controlled to stop running.

[0052] Working mode 3: Online working mode 1.

[0053] In the above working mode, several laser locators are magnetically attracted to different positions of the guide device 3, and an opening command is output through the control terminal 4. At this time, the control module 15 determines the level of the current laser output component 1 according to the signal output by the horizontal sensor 16. When it is identified that the position of the laser output component 1 is not horizontal, the control module 15 controls the rotation driver a22 and the rotation driver b23 to adjust the rotation angle according to the signal output by the horizontal sensor 16. When it is determined that the position of the laser output component 1 is horizontal according to the signal output by the horizontal sensor 16, the rotation driver a22 and the rotation driver b23 are controlled to stop running.

[0054] Working mode 3: Online working mode 2.

[0055] In the above working mode, the control command is output through the control terminal 4. At this time, the control module 15 controls the laser 14 to change the output beam brightness and / or flashing frequency according to the preset mode. After the positioning is completed, the stop command is output through the control terminal 4, and the control module 15 restores the output beam of the laser 14 to its original state.

[0056] The above-mentioned working mode 3 is used when working in a strong light environment, when it is difficult to capture the output light beam of the laser 14 under a bridge.

[0057] like Figure 3 As shown, the connection adjustment component 2 has two mutually perpendicular rotational degrees of freedom, which are used to adjust the rotation angle of the laser output component 1 in the two mutually perpendicular rotational degrees of freedom. The connection adjustment component 2 includes an L-shaped mounting frame 21, and the mounting frame 21 has two mutually perpendicular mounting surfaces. A rotation driver a22 is provided on one of the mounting surfaces, and the output shaft of the rotation driver a22 is connected thereto. A rotation driver b23 is provided on the other mounting surface, and the output shaft of the rotation driver b23 is connected to a mounting plate 24. The outer shell 11 is arranged on the mounting plate 24. A magnetic ring 25 is provided on the side of the rotation driver a22 away from the mounting frame 21. The signal output end of the control module 15 is communicatively connected with the rotation driver a22 and the signal input end of the rotation driver a22.

[0058] The magnetic ring 25 can be used to magnetically connect the connection adjustment component 2 and the guide device 3, which effectively improves the convenience of use.

[0059] The rotation driver a22 and the rotation driver b23 use commercially available motors as power sources to drive the laser output component 1 to rotate in two mutually perpendicular rotational degrees of freedom.

[0060] like Figure 4 As shown, the laser output component 1 includes an outer shell 11, inside of which a control module 15 and a laser 14 are arranged, wherein a side wall of the outer shell 11 has a window for laser beam output, a level sensor 16 is integrated on the control module 15, and a button 12 and a display screen 13 are arranged on the surface of the outer shell 11, wherein a signal input end of the controller is communicatively connected with a signal output end of the level sensor 16 and the button 12, and a signal output end of the controller is communicatively connected with a signal input end of the laser 14 and the display screen 13.

[0061] When there are multiple lasers 14 , there are multiple corresponding windows for outputting laser beams, and the windows for outputting laser beams correspond to the positions of the lasers 14 one by one.

[0062] When more than one laser 14 is used, different lasers 14 can be set to different colors. In working mode 3, the flashing process can turn on multiple lasers 14 at the same time to enhance the recognition of the output beam and facilitate quick finding of the output beam.

[0063] The control module 15 can control the start and stop of the laser 14 , as well as the brightness and flashing frequency of the output laser beam.

[0064] When the control module 15 receives a control instruction from the control terminal 4 or inputs a control instruction through the key 12 , the control module 15 executes the above control operation.

[0065] like Figure 2 and 5 As shown, the display screen 13 can display the current working status during the working process, such as the horizontality of the laser output component 1, the brightness and flickering frequency of the output laser beam, and the stand-alone or online mode.

[0072] S31 a, obtaining parameters of the level sensor 16 of the laser output component 1;

[0073] S32a, according to the acquired parameters, respectively control the rotation driver a22 and the rotation driver b23 to rotate, and adjust the laser output component 1 to be perpendicular to the horizontal plane of the laser beam.

[0074] The control end 4 adjusts the parameters of the laser beam output by the laser output component 1, including the following steps:

[0075] S31 b, obtaining parameters of the level sensor 16 of the laser output component 1;

[0076] S32b, according to the acquired parameters, respectively controlling the rotation driver a22 and the rotation driver b23 to rotate, and adjusting the laser output component 1 to be perpendicular to the horizontal plane of the laser beam;

[0077] S33b, the control terminal 4 controls the laser output component 1 to change the parameters of the output laser beam according to a preset mode.
