Description
Technical Field
[0001] This application relates to the field of building construction, and particularly to an automatic steel bar scribing device. Background Art
[0002] A steel bar scribing device is a device used for quickly and accurately scribing and positioning steel bars in building construction, mainly applied in the field of building steel bar layout. It simplifies the traditional manual scribing process, improves scribing efficiency and accuracy, and reduces labor intensity.
[0003] However, with the progress of automation technology, wireless communication technology, and chip technology, how to combine steel bar scribing with automation has become a research and development direction. In order to further improve efficiency and accuracy, while further reducing labor intensity, and also to protect the physical health of construction workers and reduce the impact caused by long-term contact with paint. Utility Model Content
[0004] In order to improve the problem of protecting the physical health of construction workers and reducing the impact caused by long-term contact with paint, this application provides an automatic steel bar scribing device.
[0005] An automatic steel bar scribing device provided by this application adopts the following technical solutions:
[0006] An automatic steel bar scribing device includes a vehicle body. A moving mechanism for driving the vehicle body to move is arranged below the vehicle body. A scribing mechanism for painting and scribing is arranged on the vehicle body. A wire passing hole is formed in the vehicle body, and a planning wire is passed through the wire passing hole. The moving mechanism controls the vehicle body to move along the direction of the planning wire to achieve automatic scribing.
[0007] By adopting the above technical solutions, construction workers only need to set the planning wire, then the moving mechanism automatically drives the vehicle body to move, and then the scribing mechanism scribes, thus realizing automatic scribing, greatly improving the efficiency. At the same time, it is not necessary for construction workers to push the vehicle body to move for a long time, reducing the contact time with scribing materials such as paint, and protecting the physical health of construction workers.
[0008] Optionally, a detection module is arranged inside the vehicle body. The detection module is used to detect the direction of the planning wire in the wire passing hole, obtain a detection signal and output it to the moving mechanism to control the moving direction of the vehicle body.
[0009] By adopting the above technical solutions, the movement of the moving mechanism is corrected by the detection module, so that the vehicle body accurately scribes along the direction of the planning wire, greatly improving the accuracy of automatic scribing.
[0010] Optionally, the detection module includes a pressure detection sub-module, which is used to detect the pressure of the planned line on the inner wall of the wire threading hole, obtain pressure data, and calculate the detection signal through the pressure data.
[0011] By adopting the above technical solution, the offset of the moving direction of the vehicle body on the planned line is calculated through pressure detection, so as to perform calculations, which is convenient and fast.
[0012] Optionally, the number of the pressure detection sub-modules is at least two and they are symmetrically arranged on both sides of the wire threading hole. The symmetric pressure detection sub-modules are in a group, and the detection signal is calculated through the pressure data of a group.
[0013] By adopting the above technical solution, it is only necessary to detect the pressure on the left and right, without the need for omnidirectional pressure detection, reducing the number of pressure detection sub-modules and lowering the cost.
[0014] Optionally, a flexible conduction layer is provided on the inner wall of the wire threading hole. The flexible conduction layer surrounds to form a through hole for the planned line to pass through, and the pressure detection sub-module is used to detect the pressure received by the flexible conduction layer.
[0015] By adopting the above technical solution, the planned line squeezes the flexible conduction layer, and the pressure is transmitted to the pressure detection sub-module through the deformation extrusion of the flexible conduction layer, reducing the pressure of the planned line on the pressure detection sub-module. At the same time, the detection range of the pressure detection sub-module is expanded in a different direction. That is, if the vehicle body tilts and causes the planned line to run out of the detection range on the left and right, and if it moves to the upper left corner or the upper right corner, outside the detection range of the pressure detection sub-modules on both sides, at this time, the continuity of the deformation of the flexible conduction layer will also transmit the pressure to the pressure detection sub-module, improving the detection efficiency.
[0016] Optionally, the number of the pressure detection sub-modules is at least two groups. The pressure detection sub-modules in different groups are distributed along the through direction of the wire threading hole. The planned direction data is calculated through the pressure data of different groups, and the detection signal is determined through the planned direction data.
[0017] By adopting the above technical solution, through multiple groups of pressure detection sub-modules, the accurate calculation of the offset direction of the planned line is realized, and the accuracy of automatic line marking is further improved.
[0018] Optionally, a wire winding roller is provided on the vehicle body, and the wire winding roller is used to wind the planned line.
[0019] By adopting the above technical solution, the planned line is automatically wound by the wire winding roller. After automatic line marking is completed, there is no need for construction personnel to recycle the planned line at the starting point, which is convenient and fast and improves the construction efficiency.
[0020] Optionally, the cross-section of the wire threading hole is square, a winding groove is formed in the flexible conduction layer, and the planning wire is wound on the wire take-up roller through the winding groove.
[0021] By adopting the above technical solution, the planning wire on the wire take-up roller will become thicker and thicker, which makes the height of the planning wire higher and higher. The inner wall of the square wire threading hole can make the pressure of the planning wire still be detected normally, reducing the probability that the inner wall of the circular wire threading hole will cause abnormal pressure direction due to the change of the height of the planning wire, and further improving the accuracy.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. Improve the efficiency of scribing construction;
[0024] 2. Improve the accuracy of scribing construction;
[0025] 3. Protect the physical health of construction workers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0032] The following further describes the present application in detail with reference to the Figures 1-5 accompanying drawings.
[0033] Embodiment 1 of the present application discloses an automatic steel bar scribing device. Refer to Figure 1The automatic steel bar marking device includes a vehicle body 1, and at least three moving mechanisms 11 for driving the vehicle body 1 to move are installed at the lower end of the vehicle body 1. The moving mechanism 11 includes wheels, a driving motor and a steering motor. The driving motor is used to control the rotation of the wheels, and the steering motor is used to drive the wheels and the driving motor to change the forward direction. The rotation directions of the driving motor and the steering motor are perpendicular to each other; a marking mechanism 12 for spraying paint and marking is installed on the vehicle body 1. The marking mechanism 12 includes a storage barrel 121 for storing materials and a nozzle for spraying marking or a roller for applying marking. The nozzle is downwardly used to spray materials toward the ground for marking; a threading hole 13 is opened through the position near the lower end of the vehicle body 1, and the threading hole 13 is penetrated in a horizontal position. A planning line 14 is penetrated in the threading hole 13, and the moving mechanism 11 controls the vehicle body 1 to move along the direction of the planning line 14 to realize automatic marking.
[0034] Reference Figure 1 and Figure 2 , fixing seats 141 are fixed on both ends of the planning line 14, the bottom of the fixing seat 141 is used to stick to the ground, and the fixing seat 141 is penetrated with a through hole 142 for the planning line 14 to pass through. After passing through the through hole 142, the planning line 14 is fixed in a circle, and the height of the through hole 142 is in the same horizontal plane as the height of the threading hole 13. In this embodiment, the threading hole 13 is a circular through hole, and the inner wall of the threading hole 13 is covered with a flexible conductive layer 22, and the flexible conductive layer 22 is annular. The outer side wall of the flexible conductive layer 22 is in contact with the inner wall of the threading hole 13, and the inner side wall of the flexible conductive layer 22 forms a through hole 23, and the planning line 14 passes through the through hole 23, and the diameter of the planning line 14 is adapted to the diameter of the through hole 23, that is, the outer side wall of the planning line 14 is in contact with the inner wall of the through hole 23.
[0035] Reference Figure 1 and Figure 2 and Figure 3, a detection module 2 is installed inside the vehicle body 1. If the planned line 14 is made of a material that is difficult to deform, such as a hard steel column, the detection module 2 may not be required. If the planned line 14 is a flexible line such as a rope, the detection module 2 is needed. The detection module 2 includes multiple pressure detection sub-modules 21. Every two pressure detection sub-modules 21 form a group, and there are at least two groups of pressure detection sub-modules 21. In this embodiment, the extending direction of the threading hole 13 is taken as the length direction of the vehicle body 1, the direction pointed by the gravity direction is downward, the direction opposite to the downward is upward, and the direction perpendicular to the length direction of the vehicle body 1 and at the same time perpendicular to the gravity direction is the width direction of the vehicle body 1. The two pressure detection sub-modules 21 in the same group are distributed on the inner walls on both sides of the threading hole 13 along the width direction of the vehicle body 1. That is, when the moving direction of the vehicle body 1 is deviated, the planned line 14 will offset and squeeze the flexible conduction layer 22 in the width direction of the vehicle body 1. At this time, the pressure detection sub-modules 21 on both sides will detect the corresponding pressure data. The corresponding detection signal is calculated through these pressure data and output to the moving mechanism 11 to correct the moving direction of the vehicle body 1. The most ideal situation is that the pressure detection sub-module 21 has a pressure of 0 for all.
[0036] Refer to Figure 2 , multiple groups of pressure detection sub-modules 21 are distributed along the extending direction of the threading hole 13 for detecting the degree of deviation. For example, the detection signal obtained from the pressure data of one group has a pressure data of 10N on the left side, and the detection signal obtained from the pressure data of another group has a pressure data of 5N on the left side. The interval distance between the two groups of pressure detection sub-modules 21 is 20 cm, and the elastic coefficient of the flexible conduction layer 22 is 10 N / cm. Then, the depths of the flexible conduction layer 22 at the positions of the two groups of pressure detection sub-modules 21 being squeezed can be calculated as 1 cm and 0.5 cm, and the deviation angle of the planned line 14 is This is only one correction, and subsequent continuous corrections are carried out to keep the moving direction of the vehicle body 1 constantly on the planned line 14.
[0037] Refer to Figure 2 And Figure 3 , the detection module 2 includes a processor and a database. The database is used to store threshold data and form a work log by combining the detection signal with time data. The threshold data is the allowed pressure data, which is 0 ideally, but can also be adjusted according to the actual situation. The processor is used to receive the pressure data and call the required threshold data from the database for calculation to obtain the detection signal to control the moving mechanism 11. The processor can also be included in the pressure detection sub-module 21.
[0038] The processor may include a central processing component such as a CPU or MPU, or a host system built around a CPU or MPU, including hardware or software. After the measuring instrument is equipped with a processor, people can freely control the measuring instrument through programming to make it operate according to people's wishes. The processor can control local quantity transfer, remote quantity transfer, remote communication, etc. through an internal protocol. The internal protocol generally refers to all protocols for realizing mutual communication or connection within the same measuring instrument or the same system, including: part or all of the human-computer interaction protocol, software / hardware (interface) protocol, chip bus (C-Bus) protocol, internal bus (I-Bus) protocol, etc. With the development of integrated circuit technology, some that belong to the external bus (E-Bus) protocol also belong to the internal protocol after being integrated into the chip along with the external bus (E-Bus).
[0039] The implementation principle of Embodiment 1 of this application for an automatic steel bar scribing device is as follows: If scribing is required, first align the direction of the wire threading hole 13, then pass the planning line 14 through the wire threading hole 13, then place the two fixing seats 141 at the end point and the starting point, and fix them by pressing with glue or stones, etc., and then connect the two ends of the planning line 14 to the fixing seats 141, add materials into the storage barrel 121, and then start the moving mechanism 11.
[0040] Embodiment 2:
[0041] Different from Embodiment 1, Embodiment 2 of this application discloses an automatic steel bar scribing device. Refer to Figure 4 And Figure 5 , the automatic steel bar scribing device includes a wire winding roller 3 rotatably connected to the vehicle body 1. The wire winding roller 3 is located on the outer side wall of the vehicle body 1 near the opening surface of the wire threading hole 13, and the wire winding roller 3 is located at the rear end position in the advancing direction of the vehicle body 1. That is, while the moving mechanism 11 drives the vehicle body 1 to advance, the wire winding roller 3 synchronously winds the planning line 14. In this embodiment, only one fixing seat 141 needs to be fixed at the end point. One end of the planning line 14 is wound on the wire winding roller 3, and the other end of the planning line 14 passes through the wire threading hole 13 and is fixed to the fixing seat 141.
[0042] Refer to Figure 5, the wire threading hole 13 can be a circular through hole or a square through hole. In this embodiment, the wire threading hole 13 is a square through hole, and the flexible conduction layer 22 is also square annular, so that the through hole 23 formed by enclosing the inner wall of the flexible conduction layer 22 is also square. And a winding groove 31 is penetrated through the lower end portion of the flexible conduction layer 22, and the winding groove 31 is communicated with the through hole 23. The planning wire 14 slides in the winding groove 31 and the through hole 23. One end of the planning wire 14 is wound on the wire take-up roller 3 after passing through the winding groove 31 or the through hole 23. As more and more of the planning wire 14 in the wire take-up roller 3 accumulates, the planning wire 14 on the wire take-up roller 3 will become thicker and thicker, which also makes the height of the planning wire 14 higher and higher. Therefore, it is necessary for the planning wire 14 to slide upward in the winding groove 31 for adaptation.
[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
