[0031] 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.

[0032] Reference Figure 1 - Figure 3, the utility model provides an embodiment: a steel bar detector for safety supervision of construction projects, including a table top 1, the table top 1 is used to provide support, the bottom four corners of the table top 1 are fixedly connected with legs, the legs provide support, the top of the table top 1 is fixedly connected with a support platform 8 and two groups are provided, the two groups of support platforms 8 provide support, and a feeding assembly is provided between the two groups of support platforms 8;

[0033] The feeding assembly includes a feeding box 82, and steel bars can be placed in the feeding box 82 for automatic feeding and detection. The feeding box 82 is fixedly connected to the top of the table 1 near the two groups of support tables 8. A through hole 83 is provided on the inner wall of the bottom end of the feeding box 82. The through hole 83 facilitates the downward movement of the feeding block 86, so that the front end of the feeding block 86 is parallel to the bottom inner wall of the feeding box 82, so that the steel bars can roll onto the feeding block 86. The bottom end of the feeding box 82 is fixedly connected to a support box 89 near the bottom end of the through hole 83. The support box 89 provides support. The support box 89 passes through and is fixedly connected to the bottom end of the table 1. The top of the table 1 is fixedly connected to a detector 2. The detector 2 can drive the hydraulic rod 3 to move, thereby driving the detection head 4 to move to detect the steel bars. A hydraulic rod 3 is provided at the bottom of the front end of the detector 2. The hydraulic rod 3 can drive the detection head 4 to move downward. The lower end outer wall of the hydraulic rod 3 is fixedly connected to a support plate 5, and the support plate 5 provides support.

[0034] Reference Figure 4 The top of the support plate 5 passes through and is slidably connected with a sliding rod 6, which supports a pressing block 7. The bottom end of the sliding rod 6 is fixedly connected with a pressing block 7 near the bottom end of the support plate 5. The bottom end of the pressing block 7 is set to an arc surface, which can limit the steel bar by squeezing the steel bar on the arc surface to improve the stability of the steel bar. The pressing block 7 is elastically connected to the support plate 5 through a spring 9. When the pressing block 7 contacts the steel bar, it is squeezed by the steel bar and the spring 9 is squeezed at the same time. The reverse force of the squeezing of the spring 9 makes the pressing block 7 always squeeze the steel bar to limit the position, thereby improving the stability of the steel bar limitation.

[0035] Reference Figure 1 - Figure 3 The inner wall of the support box 89 is slidably connected with a slide plate 811, and the slide plate 811 supports the steel bar. The support box 89 and the slide plate 811 are elastically connected by spring three 810. When the feed block 86 moves downward, the slide plate 811 is squeezed and the spring three 810 is squeezed at the same time. When the feed block 86 moves upward, the slide plate 811 can be reset by the reverse force of the spring three 810 being squeezed, thereby blocking the through hole 83 to prevent the steel bar from falling in. The slide plate 811 slides on the inner wall of the through hole 83, and the inner wall of the through hole 83 is plugged with a feed block 86. The feed block 86 is set to an L shape, and the bottom surface of the front end of the feed block 86 is set to an inclined surface. The top of the front end of the feed block 86 is provided with a groove, and the steel bar can roll into the front end groove of the feed block 86, and the front end groove of the feed block 86 can only accommodate one steel bar.

[0036] Furthermore, the feed block 86 is fixedly connected to the bottom end of the support plate 5, and the feed block 86 can be driven to move by the support plate 5. A detection head 4 is provided at the bottom end of the hydraulic rod 3. The detection head 4 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The front inner wall of the feed box 82 is fixedly connected with an inclined block 87, and steel bars can be placed on the inclined block 87. When the feed block 86 moves downward to be parallel to the bottom inner wall of the feed box 82, the first steel bar can be pushed by the steel bar rolling on the inclined block 87 to roll into the feed block 86 for loading. The right side of the support platform 8 is fixedly connected with an extrusion block 81, and the extrusion block 81 is in contact with the positioning plate 812.

[0037] Reference Figure 1 - Figure 3 The right side of the support platform 8 is fixedly connected with a support block 84 near the front of the extrusion block 81. The support block 84 supports the positioning plate 812 and the discharge platform 85. The rear surface of the support block 84 is slidably connected with the positioning plate 812. The positioning plate 812 can position the steel bar at the top of the positioning plate 812 after contacting the extrusion block 81. The positioning plate 812 and the support block 84 are elastically connected by a spring 88. The bottom end of the positioning plate 812 is set as an inclined surface. When the feed block 86 drives the steel bar to move upward, the bottom end inclined surface of the positioning plate 812 is squeezed by the steel bar to make the positioning plate 812 move upward. The extrusion spring 88 is moved in the direction of the front surface. When the steel bar is moved to the top of the positioning plate 812, the reverse action of the extrusion of the spring 88 can drive the positioning plate 812 to reset and contact the extrusion block 81 to support the steel bar. The top of the support block 84 is set as an inclined surface. By setting the top of the support block 84 as an inclined surface, the steel bar can be fixed from the top inclined surface of the support block 84 to the top of the discharge platform 85. The top of the support block 84 is fixedly connected to the discharge platform 85. The top of the discharge platform 85 is set as a groove shape, and the inspected steel bar can be rolled into the groove.

[0038] Working principle: When in use, after the steel bar is put into the inclined block 87 and rolled into the feed block 86, the hydraulic rod 3 is driven to move by starting the detector 2, and the support plate 5 and the feed block 86 are driven upward by the movement of the hydraulic rod 3, and the steel bar is driven upward by the movement of the feed block 86. When the steel bar contacts the bottom end inclined surface of the positioning plate 812, the bottom end inclined surface of the positioning plate 812 is squeezed, so that the positioning plate 812 moves to the front end to squeeze the spring 2 88. When the steel bar is moved to the top of the positioning plate 812, the squeezing of the positioning plate 812 is released, and the reverse force of the squeezing of the spring 2 88 is released. The positioning plate 812 is driven to reset and support the steel bar. At this time, the hydraulic rod 3 moves downward to drive the support plate 5, the pressing block 7, the sliding rod 6, and the feed block 86 to move downward. When the pressing block 7 moves to contact the steel bar, it squeezes the steel bar and squeezes the spring 9 at the same time. The reverse force of the squeezed spring 9 and the bottom arc surface of the pressing block 7 make it possible to limit the steel bar. At this time, the detection head 4 contacts the steel bar for detection. At the same time, the bottom end of the feed block 86 is set as an inclined surface to squeeze the steel bar toward the front end. After that, the feed block 86 slides into the through hole 83 to squeeze the slide plate 811, and the spring three 810 is squeezed through the slide plate 811.

[0039] When the top of the feed block 86 is parallel to the inner wall of the feed box 82, multiple steel bars are pushed from the inclined block 87, so that a steel bar rolls into the feed block 86, and then the hydraulic rod 3 moves upward to drive the support plate 5, the pressing block 7, and the feed block 86 to move upward. At the same time, the reverse force of the spring 3 810 being squeezed drives the slide plate 811 to slide to the through hole 83, blocking the through hole 83, thereby preventing the bottom steel bar from falling from the through hole 83. The squeezing of the spring 1 9 is released by the movement of the support plate 5, and the pressing block 7 is driven to move to release the limitation of the steel bar. When the feed block 86 drives the next steel bar to move to the positioning plate 812 After the bottom end, the bottom end slope of the positioning plate 812 is squeezed, so that the positioning plate 812 moves to the front end to squeeze the spring 2 88, and at the same time, the tested steel bars are pushed through the front end of the feed block 86, and the tested steel bars are pushed into the discharge table 85. At the same time, the reverse force of the spring 2 88 is squeezed to push the positioning plate 812 to reset and support the next steel bar, thereby continuing to move the hydraulic rod 3 downward, driving the detection head 4 to perform detection, and at the same time continuing to put the next steel bar into the feed block 86 for batch detection. There is no need to manually replace the steel bars, which improves the convenience of detection. At the same time, batch detection can be performed to improve the detection efficiency.
