[0025] Embodiment 1, as Figure 1 - Figure 6 As shown, the utility model provides a steel bar spacing detection device for highway bridge construction, including a ruler body 1, a limiting mechanism 2 is arranged on one side of the ruler body 1, a through groove 3 is provided at the bottom of the ruler body 1, a moving block 4 is arranged in the ruler body 1, a limiting shell 5 is sleeved on the outer surface of the moving block 4, a movable benchmark 6 is fixedly connected to the bottom of the limiting shell 5, a limiting hole 7 is provided on one side of the limiting shell 5, a sliding groove 8 is provided on one side of the moving block 4, a first return spring 9 is fixedly connected in the sliding groove 8, a sliding rod 10 is slidably connected in the sliding groove 8, one end of the sliding rod 10 is fixedly connected to the first return spring 9, and the other end of the sliding rod 10 is fixedly connected to the limiting block 11.

[0026] The effect achieved by the entire embodiment 1 is that when the movable mark rod 6 needs to be disassembled or replaced, the two limit blocks 11 are pressed so that the two limit blocks 11 drive the two slide bars 10 to approach each other, and then the limit shell 5 can be pulled out from the moving block 4, thereby facilitating the disassembly or replacement of the movable mark rod 6. When it needs to be installed, the two limit blocks 11 are first pressed to insert the moving block 4 into the limit shell 5, so that the two slide bars 10 approach each other and squeeze the two first return springs 9. Under the elastic force of the two first return springs 9, when the moving block 4 is inserted to the target position, the two slide bars 10 drive the two limit blocks 11 to squeeze into the two limit holes 7, thereby limiting the limit shell 5, which is convenient for installing the movable mark rod 6.

[0027] Embodiment 2, as Figure 1 - Figure 6As shown, a threaded rod 12 is rotatably connected in the ruler body 1, and the smooth end of the threaded rod 12 is movable and penetrates the ruler body 1. A rotating cap 13 is fixedly installed on the smooth end of the threaded rod 12. The moving block 4 is sleeved on the outer surface of the threaded rod 12. A limiting groove 14 is provided on the inner top of the ruler body 1. A limiting plate 15 is slidably connected in the limiting groove 14. The bottom of the limiting plate 15 is fixedly connected to the moving block 4. The limiting mechanism 2 includes a placement groove 201. The placement groove 201 is provided on one side of the ruler body 1. A fixed connection is provided in the placement groove 201. There is a fixed rod 202, the outer surface of the fixed rod 202 is sleeved with a second return spring 203, the outer surface of the fixed rod 202 is sleeved with a pressure plate 204, the bottom of the pressure plate 204 is fixedly connected with a pressure block 205, the material of the pressure block 205 is rubber, and the inner surface of the pressure block 205 is provided with anti-slip protrusions, the top of the pressure plate 204 is fixedly installed with a first handle 206, the top of the ruler body 1 is fixedly installed with a second handle 16, the front side of the ruler body 1 is provided with a scale 17, and the bottom of the ruler body 1 is clamped with a fixed mark rod 18.

[0028] The effect achieved by the entire embodiment 2 is that by rotating the rotating cap 13, the rotating cap 13 drives the threaded rod 12 to rotate. Since the limit plate 15 limits the moving block 4, the threaded rod 12 drives the moving block 4 to move, and the moving block 4 drives the limit plate 15 to slide synchronously in the limit groove 14, thereby driving the movable mark rod 6 to move, so as to facilitate the adjustment of the position of the movable mark rod 6 to determine the spacing of the steel bars. Then, by setting the limiting mechanism 2, the two first handles 206 are pulled to make the two first handles 206 move away from each other, so that the two pressing plates 204 move away from each other, and at the same time, the second return spring 203 is squeezed and begins to shrink. After the position of the movable mark rod 6 is adjusted by rotating the rotating cap 13, the two first handles 206 are released. Under the elastic force of the second return spring 203, the two pressing blocks 205 are driven to clamp and fix the threaded rod 12 to prevent the threaded rod 12 from rotating and affecting the spacing detection result. Then, by providing the second handle 16, it is convenient for the staff to take it, and a scale 17 is provided, so that the movable mark rod 6 can detect the spacing through the scale 17.

[0029] Working principle: when measuring the spacing between the steel bars, first pull the two first handles 206 to move the two first handles 206 away from each other, so that the two pressure plates 204 move away from each other, and at the same time the second return spring 203 is squeezed and starts to shrink, then rotate the rotating cap 13, so that the rotating cap 13 drives the threaded rod 12 to rotate, and since the limit plate 15 limits the moving block 4, the threaded rod 12 drives the moving block 4 to move, and the moving block 4 drives the limit plate 15 to slide synchronously in the limit groove 14, thereby driving the movable mark rod 6 to move, and the spacing of the steel bars is determined by adjusting the position of the movable mark rod 6. After the position of the movable mark rod 6 is adjusted, release the two first handles 206, and under the elastic force of the second return spring 203, drive the two pressure blocks 205 to clamp and fix the threaded rod 12, avoiding The threaded rod 12 is prevented from rotating to prevent affecting the spacing detection result. The steel bar spacing is then detected by the scale 17. When the movable benchmark 6 needs to be disassembled or replaced, the two limit blocks 11 are pressed, so that the two limit blocks 11 drive the two slide bars 10 to approach each other, and then the limit shell 5 can be pulled out from the moving block 4, so that the movable benchmark 6 can be disassembled or replaced. When it needs to be installed, the two limit blocks 11 are first pressed to insert the moving block 4 into the limit shell 5, so that the two slide bars 10 approach each other and squeeze the two first return springs 9. Under the elastic force of the two first return springs 9, when the moving block 4 is inserted to the target position, the two slide bars 10 drive the two limit blocks 11 to squeeze into the two limit holes 7, thereby limiting the limit shell 5 and facilitating the installation of the movable benchmark 6.
