[0026] By rotating one buckle ring 31 , the axes of the two buckle rings 31 can be made perpendicular to each other, so that the two buckle rings can be respectively connected to two perpendicular positioning rods, thereby realizing the connection of the two positioning rods.

[0027] The buckle ring 31 includes two rotatably connected buckling parts 311. The rotatably connected manner of the two buckling parts 311 is a common manner in the technical field and is not specifically limited here.

When in use, one buckle part 311 can be rotated to open, and the opened buckle ring 31 is buckled on the positioning rod, and then the buckle part 311 is rotated again to close the buckle ring 31, and then the two buckle parts 311 are locked by bolts 312, so that the buckle ring 31 can be buckled and connected to the positioning rod.

[0028] When the first positioning rod 21 needs to be rotated, the buckle 31 connected to one end of the first positioning rod 21 can be opened, so that one end of the first positioning rod 21 is separated from the buckle 31. The other end of the first positioning rod 21 is also connected to the buckle 31, and the buckle 31 is rotatable, so that the first positioning rod 21 can be rotated, and the first positioning rod 21 can be rotated around the rotating shaft 32 of the rotating fastener 30 connected to the other end thereof.

The steel section 100 is in the positioning space, and the length and / or width of the positioning space can be adjusted, so that the positioning device of this embodiment can adapt to steel sections 100 of different sizes and can position steel sections 100 of different sizes.

[0030] In this embodiment, the first positioning modules 24 connected to the multiple first positioning rods 21 are located on the same vertical straight line, the second positioning modules 25 connected to the multiple second positioning rods 22 are located on the same vertical straight line, and the third positioning modules 26 connected to the multiple second positioning rods 22 are located on the same vertical straight line; the multiple first positioning modules 24 and the multiple second positioning modules 25 limit the outer side surface of the same flange plate 101, and the multiple third positioning modules 26 limit the outer side surface of another flange plate 101.

[0031] Before positioning the steel section 100 , the width M of the flange plate 101 and the sum N of the thickness of the two flange plates 101 and the width of the web plate 102 are measured. According to the width M of the flange plate 101, the spacing between the first positioning rod 21 and the second positioning rod 22 is adjusted so that the spacing between the first positioning rod 21 and the second positioning rod 22 is 1-10 mm more than the width M of the flange plate 101, and the first positioning rod 21 and the second positioning rod 22 can limit the two side edges of the flange plate 101 respectively; according to the sum N of the thickness of the two flange plates 101 and the width of the web 102, the spacing between the second positioning module 25 and the third positioning module 26 is adjusted so that it is 1-10 mm more than N, and the second positioning module 25 and the third positioning module 26 limit the outer side surfaces of the two flange plates 101 respectively; then the position of the first positioning module 24 is adjusted so that the straight line formed by the first positioning module 24 and the second positioning module 25 is perpendicular to the first positioning rod 21, and the first positioning module 24 and the second positioning module 25 limit the outer side surface of the same flange plate 101.

[0033] Preferably, the spacing between the first positioning rod 21 and the second positioning rod 22 is 1-5mm more than the width M of the flange plate 101, and the spacing between the second positioning module 25 and the third positioning module 26 is 1-5mm more than N; the steel section 100 can be accurately positioned so that the steel section 100 can maintain a vertical state; and the steel section 100 can be smoothly sunk, effectively preventing the steel section 100 from being stuck in the positioning space and unable to move down and sink.

[0034] In this embodiment, by adjusting the distance between the first positioning rod 21 and the second positioning rod 22, and adjusting the distance between the second positioning module 25 and the third positioning module 26, and adjusting the first positioning module 24 and the second positioning module 25 to the same straight line (the straight line is perpendicular to the first positioning rod 21), the length and width of the positioning space can be adjusted, so that the positioning device can adapt to steel sections 100 of different sizes.

[0035] By moving the positioning frame, the positioning frame is moved above the target position, and the steel section 100 is positioned in the positioning frame, so that the steel section 100 can be positioned above the target position, so that the steel section 100 can be aligned with the target position and accurately sunk to the target position without deviation, thereby improving the accuracy of the sinking and positioning of the steel section 100; the steel section 100 can be accurately sunk at the target position, effectively preventing the steel section 100 from deviating from the target position.

[0038] In this embodiment, the first positioning module 24 , the second positioning module 25 and the third positioning module 26 may all be rectangular parallelepiped, and the plane on the positioning module parallel to the outer side surface of the flange plate 101 is the limiting surface, which can achieve more effective positioning of the steel section 100 .

[0039] The ends of the positioning modules are fixedly connected with buckles, and the positioning modules can be detachably connected to the positioning rods through the buckles; the buckles connected to the ends of the positioning modules can be Figure 7 The shape and structure of the buckle ring 31 shown can realize the connection and removal of the positioning module conveniently and quickly, thereby facilitating the adjustment of the connection position of the positioning module.

[0041] A directional pulley 43 is provided at the bottom of the connecting rod 41, and the directional pulley 43 can slide along the slide groove 10. Through the sliding of the directional pulley 43, multiple positioning frames can be driven to slide along the slide groove at the same time, so that the position of the positioning frame can be adjusted.

[0042] A brake switch 44 is provided at the bottom of the connecting rod 41, and the brake switch 44 controls the rotation of the directional pulley 43. When the positioning frame moves to the target position, the directional pulley 43 can be controlled by the brake switch 44 to limit the rotation of the directional pulley 43, so that the positioning frame can be positioned at the target position to prevent the positioning frame from moving.

[0043] like Figure 6As shown, the slide groove 10 is in the shape of a rectangular parallelepiped, and an open groove 11 is provided at the top of the slide groove 10 along its length direction.

The bottom of the anchoring nail 13 is fixed to the ground, so that the slide 10 can be fixed on the ground to ensure that the slide 10 is stable and not affected by collision.
