[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 4 As shown, an embodiment of the utility model provides a steel bar skeleton detection device, which includes a truss 10, a detection component 20, and a carrying component 30. The detection component 20 includes a first driving member 21 and a detection member 22. The detection member 22 is arranged on the truss 10, and the first driving member 21 is driven and connected to the detection member 22 so that the detection member 22 moves along the length direction of the truss 10; the carrying component 30 includes a second driving member and a carrying vehicle 31, and the carrying vehicle 31 is located below the detection member 22. The second driving member is driven and connected to the carrying vehicle 31 so that the carrying vehicle 31 can be movably arranged in the truss 10 along the length direction of the truss 10, and the carrying vehicle 31 has a detection position located inside the truss 10 and a loading and unloading position located outside the truss 10.

[0028] The technical solution of the utility model is applied, and the steel bar skeleton detection device includes a truss 10, a detection component 20 and a carrier component 30. When it is necessary to detect whether the steel bar skeleton is qualified, the carrier 31 is moved to the loading and unloading position outside the truss 10, and the steel bar skeleton is hoisted onto the carrier 31. The carrier 31 is driven by the second driving member to move along the length direction of the truss 10, so that it moves from the loading and unloading position to the detection position inside the truss 10, and the first driving member 21 is used to drive the detection member 22 to move along the length direction of the truss 10, so that the detection member 22 detects the steel bar skeleton to determine whether the steel bar skeleton is qualified. Compared with the manual detection method, the detection accuracy and detection efficiency are improved, and manpower is saved.

[0029] In this embodiment, there are two detection members 22 , and the two detection members 22 are spaced apart from each other along the width direction of the truss 10 .

[0030] Specifically, the detection part 22 includes a laser measuring instrument. The measuring principle of the laser measuring instrument is to use a line laser and a large target area array camera array. The line laser irradiates the longitudinal and transverse sections of the steel skeleton at a certain angle (preferably 60°) in parallel. The area array camera takes pictures to obtain intermittent line laser images. The image is pre-processed to extract the coordinates of the center position of the laser line. Then, according to the trigonometric relationship, the height of the skeleton can be finally obtained. At the same time, the edge pixel points of the line laser are analyzed to obtain the length and width of the skeleton. Under the irradiation of the line laser, each steel bar forms a line segment of a certain width in the area array camera. The pixel length of the line segment is obtained by image processing. The corresponding diameter of the steel bar can be obtained by calibrating the skeleton model, thereby obtaining the corresponding model of the steel bar.

[0031] like Figure 1 and Figure 2 As shown, the detection member 22 is adjustably arranged on the truss 10 along the width direction of the truss 10. With the above arrangement, when different types of steel bar skeletons are detected, the detection range of the detection member 22 can be adjusted by adjusting the position of the detection member 22 along the width direction of the truss 10.

[0032] like Figure 1 As shown, the carrier assembly 30 further includes a crossbeam 40 movably arranged on the truss 10 along the length direction of the truss 10, a slide groove extending along the length direction thereof is arranged on the crossbeam 40, and a slider is arranged on the detection member 22, and the slider is slidably arranged in the slide groove. The above arrangement has the advantages of simple structure and easy adjustment.

[0033] like Figure 1As shown, the carrier 31 also has an unqualified unloading position located outside the truss 10, and the unqualified unloading position is located at one end of the detection position away from the loading and unloading position. By setting the unqualified unloading position, when the steel skeleton is detected to be qualified, the steel skeleton can be unloaded to the loading and unloading position, and when the steel skeleton is unqualified, the steel skeleton can be unloaded to the unqualified unloading position to distinguish them.

[0034] like Figure 1 As shown, the steel bar skeleton detection device also includes a first position detection member 11, a second position detection member 12 and a third position detection member 13 arranged at intervals along the length direction of the truss 10. The first position detection member 11 is arranged corresponding to the loading and unloading position, the second position detection member 12 is arranged corresponding to the detection position, and the third position detection member 13 is arranged corresponding to the unqualified unloading position. With the above arrangement, the first position detection member 11, the second position detection member 12 and the third position detection member 13 can be used to limit the position of the carrier 31 respectively, so that the automatic control of the carrier 31 can be realized.

[0035] In this embodiment, the first position detection member 11, the second position detection member 12 and the third position detection member 13 are all travel switches.

[0036] The steel bar skeleton detection device further includes a controller and a detection data processor. The controller is respectively connected to the first driving member 21, the second driving member, the first position detection member 11, the second position detection member 12, the third position detection member 13 and the detection member 22 by signal, and the detection member 22 is connected to the detection data processor by signal. The controller can control the first driving member 21, the second driving member, the first position detection member 11, the second position detection member 12, the third position detection member 13 and the detection member 22. The detection data processor can process the data of the steel bar skeleton detected by the detection member 22 to determine whether the steel bar skeleton is qualified.

[0037] In this embodiment, the steel bar skeleton detection device also includes an industrial computer, which is used as a host computer to connect to the controller signal, and the operation instructions are transmitted to the controller by operating the industrial computer.

[0038] Specifically, the industrial computer transmits the operation instruction to the controller, the controller controls the second driving member, and the second driving member drives the carrier 31 to move along the length direction of the truss 10. When the carrier 31 moves to the first position detection member 11, the first position detection member 11 transmits a signal to the controller, thereby controlling the carrier 31 to stay at the loading and unloading position, and hoisting the steel skeleton onto the carrier 31. The second driving member drives the carrier 31 to move along the length direction of the truss 10. When the carrier 31 moves to the second position detection member 12, the second position detection member 12 transmits a signal to the controller, thereby controlling the carrier 31 to stay at the detection position. The controller controls the first driving member 21, and the first driving member 21 drives the detection member 22 to move along the length direction of the truss 10. At the same time, the steel skeleton is detected, and the detected data is transmitted to the detection data processor, and the detection data processor is used to process the data to determine whether the steel skeleton is qualified. For qualified steel bar skeletons, the controller controls the carrier 31 to move along the length direction of the truss 10. When the carrier 31 moves to the first position detection member 11, the first position detection member 11 transmits a signal to the controller, thereby controlling the carrier 31 to stay at the loading and unloading position to unload qualified steel bar skeletons. For unqualified steel bar skeletons, the controller controls the carrier 31 to move along the length direction of the truss 10. When the carrier 31 moves to the third position detection member 13, the third position detection member 13 transmits a signal to the controller, thereby controlling the carrier 31 to stay at the unqualified unloading position to unload unqualified steel bar skeletons.

[0039] Among them, the industrial computer realizes the control of the lower computer through secondary development of the basic data acquisition software. It also has data acquisition and data processing functions. It processes the initial messy point cloud data through point cloud segmentation, supplementation, merging and other algorithms, and then converts the point cloud data into image data. It identifies and locates various types of steel bars in the steel skeleton, and finally processes the data to calculate the steel bar diameter and spacing, count the number of steel bars, and output the inspection report.

[0040] like Figure 2 As shown, the carrier assembly 30 further includes a meshing gear and a rack 32, the first driving member 21 includes a motor disposed on the crossbeam 40, the gear is sleeved on the output shaft of the motor, and the rack 32 is disposed on the truss 10 and extends along the length direction of the truss 10. With the above arrangement, the first driving member 21 can drive the crossbeam 40 to move along the extension direction of the rack 32 through gear transmission, so as to drive the detection member 22 to move along the length direction of the truss 10.

[0041] In this embodiment, guiding grooves and guide rails are provided between the cross beam 40 and the truss 10 for guiding cooperation.

[0042] like Figure 1As shown, the steel bar skeleton detection device further includes a transport rail 33 passing through the truss 10 along the length direction of the truss 10, and the transport vehicle 31 is slidably arranged on the transport rail 33. The transport rail 33 can be used to move the transport vehicle 31 along the extension direction of the transport rail 33.

[0043] In this embodiment, the second driving member is a servo motor, and cooperates with a reducer to drive the carrier 31.

[0044] like Figure 1 As shown, a frame positioning plate 311 is provided on the carrier 31, and the frame positioning plate 311 includes a transverse plate capable of being limitedly matched with the transverse surface of the steel frame and a longitudinal plate capable of being limitedly matched with the longitudinal surface of the steel frame. The frame positioning plate 311 can be used to realize the positioning of the steel frame.

[0045] This detection device is used to perform non-contact measurement of the steel bar skeleton based on visual data measurement and detection methods. It is more efficient than the contact measurement method, and the detection time cycle can be controlled within 1.5 minutes.
