DETAILED DESCRIPTION

[0034] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Embodiment 1:

[0036] like Figure 1-Figure 4As shown, the embodiment provides a multi-directional building material detection tool, which includes a base 1, and a workbench 2 is arranged on the upper end of the base 1.

[0037] In order to facilitate the installation of steel bars, a pair of bearing seats for placing steel bars, a moving mechanism capable of controlling the relative movement of the two bearing seats, and a control box 3 capable of controlling the operation of the whole machine are symmetrically arranged at the upper end of the workbench 2. The tensile test of the steel bars is completed by the movement of the bearing seats. A control panel 301 for operation is also arranged on the control box 3. The control box 3 has a built-in logic processor, and the control and data are displayed through the control panel 301.

[0038] A dotting machine 4 for marking steel bars is also arranged on the workbench 2. The dotting machine 4 is a finished product machine of the prior art, which is fixedly installed on the workbench 2 to facilitate marking of the steel bars during inspection.

[0039] Specifically, the bearing seat includes a bearing plate 5 slidably connected to the base 1 and a clamping plate 6 arranged above the bearing plate 5. The bearing plate 5 is also provided with an adjusting mechanism capable of controlling the up and down movement of the clamping plate 6, including a driving mechanism providing a power source and a guiding mechanism for guiding the movement of the clamping plate 6; wherein the driving mechanism includes a servo motor 8 arranged in the bearing plate 5, a threaded rod 9 threadedly connected to the clamping plate 6 is arranged at the rotating end of the servo motor 8, the guiding mechanism includes a guide rod 10 arranged on the bearing plate 5 and a guide groove 11 slidably connected to the guide rod 10 on the clamping plate 6, the threaded rod 9 is driven to rotate by the servo motor 8, and the rotation of the threaded rod 9 can control the clamping plate 6 threadedly connected thereto to move along the guide plate 10. In order to improve the stability of the movement of the clamping plate 6, the threaded rod 9 can be arranged at the center position, and the guide rod 10 and the guide groove 11 are arranged in two and symmetrically.

[0040] A plurality of stations 7 for placing steel bars are symmetrically arranged at one end adjacent to the bearing plate 5 and the clamping plate 6, and a clamp mechanism for clamping steel bars is movably installed on each station 7, and the clamp mechanism includes a plurality of clamps 12 of different specifications, and all the clamps 12 are detachably mounted on the station 7 by screws. The station 7 is a mounting groove for installing the clamp 12. In order to improve the clamping accuracy of the clamp 2, a dovetail groove 701 is arranged on the station 7, and a slider 1201 adapted to the dovetail groove 701 is arranged on the clamp 12. During installation, the dovetail groove 701 plays a precise positioning role, thereby ensuring that the clamps 12 on the bearing plate 5 and the clamp 6 can cooperate with each other to clamp the steel bars. The clamp 12 is an iron block that can be placed in the station 7, and is fixed to the station 7 by screws through screw holes reserved on the station 7. The end of the clamp 12 in contact with the steel bar is arranged in multiple specifications for matching different types of steel bars, and the end of the clamp 12 in contact with the steel bar is arranged with a texture matching the texture of the steel bar, so as to clamp the steel bar firmly.

[0041] In order to improve the storage effect of a plurality of clamps 12 , a tool box 201 capable of storing the clamps 12 is arranged at the bottom of the workbench 2 , which is more convenient to use and avoids the loss of the clamps 12 .

[0042] Among them, the moving mechanism includes a double-headed stud 13 connected to the control box 3 and capable of controlling the relative movement of the two bearing plates 5. The two bearing plates 5 are respectively connected to the double-headed stud 13 in two directions of threads. Two sprocket wheels 14 are arranged at one end of the double-headed stud 13 located in the control box 3. Chains 15 for transmission are arranged on the two sprocket wheels 14. A servo motor 16 connected to the chain 15 is also arranged in the control box 3. A sprocket 17 connected to the chain 15 is arranged at the driving end of the servo motor 16. The chain 15 is driven by the servo motor 16, thereby synchronously driving the two double-headed studs 13 to rotate, and then synchronously controlling the movement of the bearing plates 5 threadedly connected thereto. Since it is a double-headed threaded column 13, the two bearing plates 5 can be synchronously controlled to move in opposite directions, thereby being able to stretch the steel bars.

[0043] Embodiment 2:

[0044] like Figure 1 and Figure 2 As shown, on the basis of Example 1, in order to realize the strength detection of the steel bars, a pressure mechanism capable of applying pressure to the steel bars is arranged directly above the bearing seat, specifically including a bracket 18 arranged above the workbench 2, an electric push rod 19 is arranged at the center of the bracket 18, a pressure plate 20 is arranged at the telescopic end of the electric push rod 19, and a plurality of pressure heads 21 in contact with the steel bars are arranged on the pressure plate 20, and the number of the pressure heads 21 is consistent with the maximum number of placed steel bars, and the pressure heads 21 are controlled by the electric push rod 19 to descend and contact with the steel bars, and the pressure heads continue to descend to bend the steel bars.

[0045] A data acquisition device for collecting pressure data is arranged at the position where the pressure head 21 is installed on the pressure plate 20. The data acquisition device is a pressure sensor connected to the control box 3. The pressure sensor transmits the numerical value to the control box 3 in real time for statistical archiving.

[0046] In order to avoid the steel bar from hitting the workbench and affecting the detection data when bending, a clearance groove 22 for steel bar detection is arranged on the workbench 2 just below the pressing plate 20. When the steel bar is pressed down to bend the steel bar, a clearance space is reserved for the steel bar to bend down.

[0047] Working principle: When inspecting the steel bars, first fix the steel bars. According to the specifications of the intercepted steel bars, select the appropriate clamp 12, drive the threaded rod 9 to rotate through the servo motor 8 to raise the clamp 6, prepare the installation space for the installation of the clamp 12, then align the slider 1201 with the dovetail groove 701, install the clamp 12 into each station 7, and finally fix it by inserting screws, then place the steel bars on the clamp 12 on the bearing plate 5, drive the threaded rod 9 to rotate through the servo motor 8 to lower the clamp 6 until the steel bars are clamped, and when the steel bars need to be removed, control the servo motor 8 to rotate in the opposite direction;

[0048] When testing the tensile force of the steel bar, first use a dotting machine to mark the surface of the steel bar, then use the above-mentioned clamping method to clamp the marked steel bar, and use the servo motor 16 to drive the chain 15, and use the chain 15 to synchronously drive the two studs 13 to rotate, thereby synchronously controlling the movement of the bearing plate 5 threadedly connected thereto. Under the action of the studs 13, the two bearing plates 5 are synchronously controlled to move in different directions, thereby stretching the steel bar. Finally, the stretching change of the steel bar is calculated based on the change in the spacing of the marked points on the steel bar, so that the data on the tensile force that the steel bar can withstand can be understood. By stretching multiple steel bars at the same time and taking the average value, the accuracy of the data is improved.

[0049] When measuring the strength of the steel bar, after the steel bar is fixed by the above-mentioned clamping method, the electric push rod 19 is controlled to drive the pressure head 21 to press down to bend the steel bar, and the pressure data of the pressure head 21 is detected in real time by the pressure sensor, and the data is transmitted to the control box 3.

[0050] Since multiple workstations are arranged, multiple steel bars can be inspected at the same time, and the inspection structure takes the average value for calculation, which improves the inspection efficiency while also improving the inspection accuracy.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
