Description

Technical field:

[0001] The utility model relates to the technical field of positioning, in particular to a steel pipe welding positioning mechanism. Background technology:

[0002] The process flow of the small space concrete I-beam steel composite formwork support system is formwork production → formwork assembly → accurate formwork layout → installation of embedded parts and preliminary mold closing → installation of formwork support rods → insertion of tension bolts → installation of column hoops or wall main beams → uniform adjustment of rod supports → inspection of formwork verticality → tightening of formwork, etc. When uniformly adjusting the rod supports, it is necessary to uniformly weld multiple locating ribs on the top of the I-beam while ensuring that the center of the locating rib is in the same vertical line as the center of the bottom support steel pipe, in order to increase the force in the same vertical direction. It is necessary to use a positioning mechanism to position the locating rib to ensure that the center of the locating rib is in the same vertical line as the center of the bottom support steel pipe.

[0003] The existing positioning rib positioning mechanism is mainly composed of a catheter and two hooks. The two hooks are rotatably sleeved on the catheter. The two hooks are connected by mortise and tenon joints to form a scissors-like connection to clamp and position the bottom steel pipe. Then, positioning ribs are placed on the side wall of the transverse tube of the catheter and welded to the I-beam. After one positioning rib is welded, it is necessary to weld another positioning rib. The staff needs to pinch the hook downward to realize the opposite or opposite rotation of the two hooks, and then slide to the other bottom support steel pipe and then clamp it on its surface for positioning. When the hook is clamped on the bottom support steel pipe, the staff needs to lower their heads to observe and position it. The positioning operation process of the bottom support steel pipe is complicated, and accidents may occur easily if you are not careful. High-altitude construction increases the risk of work.

[0025] like Figure 1-Figure 5 As shown, the utility model provides the following technical solutions: a steel pipe welding positioning mechanism, including a catheter 1, a vertical tube of the catheter 1 is fitted with two hooks 2 for rotation, the arc grooves on the two hooks 2 are arranged in opposite directions, the catheter 1 is fixed with two limit rings 3, the hook 2 is arranged between the two limit rings 3 and fits with the surface thereof, a groove 5 is formed on the top surface of the hook 2, a spring 4 is arranged in the groove 5, the spring 4 is sleeved on the vertical tube of the catheter 1 and one end is fixedly connected to the side wall of the vertical tube of the catheter 1, the other end of the spring 4 is fixedly connected to the surface of the hook 2, a positioning component is fixedly connected inside the vertical tube of the catheter 1, and the positioning component can limit the rotation of the hook 2.

[0026] A positioning groove 16 is provided on the side wall of the transverse tube of the conduit 1. The cross-section of the positioning groove 16 is arc-shaped, which is convenient for placing the positioning rib for positioning.

[0027] The top surface of the hook 2 at the bottom end is arranged to fit with the bottom surface of the hook 2 at the top end, thereby improving the stability of the two hooks 2 when rotating.

[0028] Please combine Figure 1 As shown, during use, when it is necessary to weld the positioning ribs, first place the transverse tube of the conduit 1 on the top surface of the I-beam, then pull the conduit 1 to slide, and the conduit 1 drives the hook 2 to slide and gradually fit the surface of the bottom support steel pipe, and the bottom support steel pipe pushes the hook 2 with the arc groove facing away from the support steel pipe to rotate, and the hook 2 gradually rotates to push the positioning component to move, and the positioning component cancels the limit on the hook 2, and at this time the spring 4 drives the hook 2 to rotate around the bottom support steel pipe and fit the surface of the bottom support steel pipe again, thereby achieving the two hooks 2 to hold the bottom support steel pipe Clamp it for positioning, then place the positioning rib vertically into the positioning groove 16, and then weld the positioning rib to the top surface of the I-beam. The setting of the limit ring 3 limits the hook 2 to improve the stability of the hook 2. After the welding of the positioning rib is completed, the corresponding supporting steel pipe is put on the positioning rib and then the supporting steel pipe and the top surface of the I-beam are welded to ensure that the supporting steel pipe at the bottom is in the same vertical straight line. After the elastic potential energy of the spring 4 is released, the hook 2 can be rotated in the opposite direction. The rotation of the hook 2 drives the spring 4 to be gradually tightened to store the elastic potential energy.

[0029] After the positioning rib is welded, the catheter 1 is directly pulled to move, and the catheter 1 drives the hook 2 to move. At this time, the bottom support steel pipe will push a hook 2 to rotate, and the rotation of the hook 2 drives the positioning component to move to cancel the rotation of the hook 2. The spring 4 drives the hook 2 to rotate and separate from the bottom support steel pipe, thereby realizing the separation of the two hooks 2 from the bottom support steel pipe. When sliding to the other bottom support steel pipe, the bottom support steel pipe will push the other hook 2 to rotate. The hook 2 drives the positioning component to move and cancel the rotation of the hook 2. The corresponding spring 4 drives the hook 2 to rotate and clamp the bottom support steel pipe again for positioning. The positioning ribs are placed in the above manner to weld the positioning ribs. There is no need to manually pinch the hook 2 to achieve the closure of the hook 2, and there is no need for the staff to lower their heads to observe and position. The operation is simple and the safety factor is improved.

[0030] Please combine Figure 1 , Figure 3 , Figure 4 As shown, an embodiment of the positioning component includes a compression spring 7 fixed in the vertical tube of the catheter 1, one end of the compression spring 7 is fixedly connected to a slide rod 6, one end of the slide rod 6 passes through the catheter 1 and passes into an arc groove 8, the arc groove 8 is provided on the surface of the hook 2, the slide rod 6 is slidably connected to the catheter 1 and the arc groove 8 respectively, the cross-section of the slide rod 6 close to the arc groove 8 end is an arc surface, and the elastic force of the compression spring 7 is much greater than the elastic force of the spring 4.

[0031] Please combine Figure 1 As shown, during use, when the bottom supporting steel pipe pushes the hook 2 to rotate, the hook 2 drives the arc groove 8 to rotate, and the arc groove 8 drives the slide bar 6 to move and squeeze the compression spring 7 to deform. The slide bar 6 moves and gradually retracts into the conduit 1 to cancel the limit on the hook 2. At this time, the corresponding spring 4 drives the hook 2 to rotate, and stops rotating when the arc groove on the hook 2 is stuck on the bottom supporting steel pipe, or when the hook 2 drives the arc groove 8 to rotate and corresponds to the slide bar 6 again, the deformed compression spring 7 drives the slide bar 6 to slide and insert into the arc groove 8 again to limit the hook 2 so that the hook 2 cannot rotate.

[0032] Two T-shaped slide bars 9 are slidably provided in the vertical tube of the catheter 1. The two T-shaped slide bars 9 are superimposed and fixedly connected to each other. The top end of the T-shaped slide bar 9 passes through the catheter 1 and is slidably connected thereto. A tension spring 10 is sleeved on the vertical bar of the T-shaped slide bar 9 at the top.

When the bottom supporting steel pipe pushes the hook 2 to rotate, the hook 2 can push the corresponding slide bar 6 to slide and cancel the limit on the hook 2. Then the T-shaped slide bar 9 at the top is loosened, and when the slide bar 6 is inserted into the arc groove 8 again, the slide bar 6 drives the through groove 12 to move and correspond to the trapezoidal slider 11 again, and the deformed tension spring 10 pulls the top T-shaped slide bar 9 to move, and the top T-shaped slide bar 9 drives the bottom T-shaped slide bar 9 to move, and the bottom T-shaped slide bar 9 drives the trapezoidal slider 11 to be inserted into the through groove 12 again to limit the slide bar 6, thereby improving the stability of the slide bar 6 and preventing the slide bar 6 from sliding unintentionally.
