[0028] An embodiment of the utility model provides a device for detecting the thickness of the steel bar protection layer for construction engineering.

[0029] Please refer to Figure 1 , including a steel bar detector 1 and a component guiding outer shell 2. The steel bar detector 1 is a prior art and will not be elaborated much. The setting of the component guiding outer shell 2 can effectively limit its internal components, ensure the stable movement of its internal components, and prevent tilting.

[0030] Please refer to Figure 1 and Figure 3 , a support extension sleeve 13 is fixedly arranged on one side of the component guiding outer shell 2. A support limiting plate 15 is slidably arranged inside the support extension sleeve 13. The setting of the support extension sleeve 13 can effectively limit the support limiting plate 15, thereby ensuring the smoothness of the support extension sleeve 13 during its own movement.

[0031] Please refer to Figure 1 , the support limiting plate 15 is rotatably connected to the special-shaped support frame 17 through a second linkage shaft 16 to ensure the flexible movement of the support limiting plate 15 and guarantee the smooth progress of subsequent detection work. The special-shaped support frame 17 is fixedly connected to the upper surface of the flat contact plate 18. The bottom of the flat contact plate 18 is subjected to frosted treatment, which can increase the resistance between the contact surface and make it easier to ensure the stability of the flat contact plate 18.

[0032] Please refer to Figure 3 , the support limiting plate 15 is fixedly connected to one end of the electric push rod 14, and the other end of the electric push rod 14 is fixedly connected to the support extension sleeve 13. The electric push rod 14 is a prior art and will not be elaborated much. The setting of the electric push rod 14 can effectively make the support extension sleeve 13 slide outside the support limiting plate 15.

[0033] Please refer to Figure 1 , Figure 4 and Figure 5 , the groove opened on the component guiding outer shell 2 is slidably connected to the linkage support plate 4 through the limiting plate 3. The close cooperation between the limiting plate 3 and the linkage support plate 4 ensures the smooth movement of the linkage support plate 4 inside the component guiding outer shell 2. There are two groups of linkage support plates 4. One side of each of the two groups of linkage support plates 4 is fixedly provided with a position control column 6. There are two groups of position control columns 6. The purpose of setting two groups of linkage support plates 4 and two groups of position control columns 6 is to make the two groups of linkage support plates 4 move relatively through the position control columns 6 under the restriction of the position control drive disk 7.

[0034] Please refer to Figure 2 and Figure 4, the linkage support plate 4 is fixedly connected to the support clamping module 5. There are two groups of support clamping modules 5, and the two groups of support clamping modules 5 are symmetrically distributed. A steel bar detector 1 is arranged between the two groups of support clamping modules 5. The support clamping module 5 is in contact with the steel bar detector 1. The purpose of setting two groups of support clamping modules 5 is to more directly ensure the stability of the steel bar detector 1, make the detection data more accurate, and not easily deviate.

[0035] Please refer to Figure 4 and Figure 5 , a position control column 6 is fixedly arranged on one side of the linkage support plate 4. The position control column 6 slides in the groove opened in the position control drive disc 7. The position control drive disc 7 is connected to the component guide housing 2 through the first linkage shaft 8. The setting of the position control drive disc 7 controls the movement of the position control column 6 through the direction of the groove opened in itself, so that the subsequent components move accordingly.

[0036] Please refer to Figure 6 and Figure 7 , a planar turbine 9 is fixedly arranged on the outer circumferential surface of the first linkage shaft 8. The teeth on the outer circumferential surface of the planar turbine 9 are meshed with the threads on the outer circumferential surface of the one-way worm 10. One end of the one-way worm 10 is fixedly provided with an external turning handle 11. The close fit between the planar turbine 9 and the one-way worm 10 can effectively transmit force and has a certain self-locking effect. The setting of the external turning handle 11 facilitates the staff to rotate the one-way worm 10.

[0037] Please refer to Figure 2 and Figure 6 , the one-way worm 10 is rotatably connected to the protective support housing 12. The protective support housing 12 is fixedly connected to the component guide housing 2. A one-way wheel 19 is arranged at the bottom of the component guide housing 2. The setting of the one-way wheel 19 makes it more convenient for the component guide housing 2 to move, and at the same time, it is not easy to deviate from the route during the movement.

[0038] Working principle: Place the planar contact plate 18 on the steel bar protective layer, hold the planar contact plate 18 by hand to enhance the stability effect of the planar contact plate 18. At this time, the one-way wheel 19 contacts the steel bar protective layer. Start the electric push rod 14 and the steel bar detector 1 to work. The electric push rod 14 pushes the support extension sleeve 13 to slide outside the support limiting plate 15. The support extension sleeve 13 drives the component guiding housing 2 to move. At this time, the one-way wheel 19 rotates on the steel bar protective layer. The component guiding housing 2 together with other components drives the steel bar detector 1 to move, and the detection work of the thickness of the steel bar protective layer can be completed. By applying an external force to rotate the external rotary handle 11, the one-way worm 10 drives the planar turbine 9 to rotate, driving the position control drive disk 7 on the first linkage shaft 8 to rotate in place. At this time, under the action of the limiting plate 3, the linkage support plate 4 is restricted by the component guiding housing 2. Under the action of the groove of the position control drive disk 7 itself, the linkage support plate 4 is driven by the position control column 6 to move horizontally inside the component guiding housing 2, increasing the distance between the two support clamping modules 5 and releasing the restriction effect on the steel bar detector 1, thus facilitating the maintenance of the steel bar detector 1.
