Description

They are installed during the pouring of the structure and are used for overlapping when building the upper structure to facilitate the installation and fixation of the foundation of external engineering equipment. Embedded parts are mostly made of metal. Embedded steel pipes are often used in actual construction. Since embedded steel pipes are designed in multiple sections during manufacturing and welded at the interface during installation, steel pipe clamps are often used to position the steel pipes to be welded to achieve auxiliary welding.
[0003] The steel pipe clamp in the prior art usually uses two ferrules to clamp the steel pipe from both sides, and then uses fixing bolts to reinforce it from both sides of the ferrules. However, due to the heavy weight and long length of the steel pipe, errors are prone to occur when using the ferrules to fix the steel pipe. After the ferrules are fixed with bolts, the interfaces of the two steel pipes cannot be accurately aligned and cannot be welded. It will also take a lot of time to adjust again after loosening the ferrules, which is not conducive to the efficiency of welding the embedded steel pipes. Utility Model Content

DETAILED DESCRIPTION
[0020] 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.
[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a pre-embedded welding positioning steel pipe clamp, comprising a support seat 1, a support rod 2 is fixedly connected to the top of the support seat 1, a top plate 3 is fixedly connected to the top of the support rod 2, a scissors-type lifting frame 4 is fixedly installed at the bottom of the top plate 3, a lifting plate 5 is fixedly connected to the bottom of the scissors-type lifting frame 4, a first fixed seat 6 and a second fixed seat 7 are fixedly connected to the bottom of the lifting plate 5, a bidirectional screw rod 8 is rotatably connected to the middle of the first fixed seat 6, one side of the bidirectional screw rod 8 is rotatably connected to the side wall of the second fixed seat 7, a first rotating handle 9 is fixedly connected to the side of the bidirectional screw rod 8 away from the second fixed seat 7, and a first sliding seat 10 and a second sliding seat 11 are threadedly connected to the surface of the bidirectional screw rod 8.
[0022] In an optional embodiment: the first sliding seat 10 is fixedly connected to the bottom with a first positioning block 12 , the second sliding seat 11 is fixedly connected to the bottom with a second positioning block 13 , and the middle parts of the first positioning block 12 and the second positioning block 13 are rotatably connected with a positioning tube 14 .
[0023] It should be noted that when in use, the device is placed on both sides of the embedded part groove so that the opening direction of the positioning tube 14 is the same as the direction of the groove. Before welding the embedded steel pipe, the scissor-type lifting frame 4 can be driven to reset, so that the scissor-type lifting frame 4 drives the lifting plate 5 to rise, thereby bringing the main body of the steel pipe clamp to the top of the groove, so as to facilitate the two steel pipes to be welded to be inserted into the positioning tube 14 for fixation. After the steel pipe is fixed, the first rotating handle 9 is rotated so that the first rotating handle 9 drives the bidirectional screw rod 8 to rotate, thereby driving the first sliding seat 10 and the second sliding seat 11 to slide toward the middle of the bidirectional screw rod 8, thereby achieving the effect of driving the welding ports of the two steel pipes to be aligned, so that the pipe ports of the steel pipes to be welded can be accurately positioned, and no additional adjustment is required to achieve alignment.
[0024] In an optional embodiment: the side of the first positioning block 12 is fixedly connected to the first fixed box 15, the side of the second positioning block 13 is fixedly connected to the second fixed box 16, a rotating rod 17 is provided in the middle of the first fixed box 15, one end of the rotating rod 17 is rotatably connected to the inner wall of the second fixed box 16, and the end of the rotating rod 17 away from the second fixed box 16 is fixedly connected to the second rotating handle 18, and both sides of the rotating rod 17 are fixedly connected to the limiting blocks 19, the first positioning block 12 and the first fixed box 15 are provided with a gear cavity 20, the outer wall of the rotating rod 17 is slidably connected to the inside of the first fixed box 15 with a driving gear 21, the middle part of the driving gear 21 is provided with limiting grooves 22 on both sides of the rotating rod 17, the inner wall of the limiting groove 22 is slidably connected to the limiting block 19, the outer wall of the positioning tube 14 is fixedly connected to the inside of the gear cavity 20 with a driven gear 23, and the driven gear 23 is meshed with the driving gear 21.
[0025] It should be noted that when the distance between the first positioning block 12 and the second positioning block 13 is reduced, the distance between the first fixed box 15 and the second fixed box 16 is also reduced synchronously. Since the end of the rotating rod 17 away from the second rotating handle 18 is rotatably connected to the inner wall of the second fixed box 16, and the middle part of the first fixed box 15 has no connection with the rotating rod 17, when the bidirectional screw rod 8 is rotated to reduce the distance between the first fixed box 15 and the second fixed box 16, the rotating rod 17 can use the inner wall of the second fixed box 16 as a reference point to achieve the sliding of the first fixed box 15 on the surface of the rotating rod 17. After the sliding is completed, the second rotating handle 18 is continuously rotated during welding so that the second rotating handle 18 can be brought The movable rotating rod 17 rotates, so that the limit block 19 on the surface of the rotating rod 17 rotates synchronously, and then the driving gear 21 inside the first fixed box 15 and the second fixed box 16 is driven to rotate under the action of the limit groove 22, so that the driving gear 21 drives the driven gear 23 to rotate under the action of the meshing connection, thereby driving the two positioning tubes 14 to rotate inside the first positioning block 12 and the second positioning block 13, and then driving the two steel pipes to rotate, so that the operator does not need to actively adjust the welding position during welding, which is convenient for use and can also avoid the welding point being blocked by the device. Through the above arrangement, it is possible to adjust the spacing between the steel pipe welding ports while driving the steel pipe to rotate, which is helpful for the efficiency of welding work.
[0026] In an optional embodiment: adjusting bolts 24 are threadedly connected to both sides of the positioning tube 14 , and a clamping plate 25 is rotatably connected to one side of the adjusting bolt 24 close to the inside of the positioning tube 14 , and the clamping plate 25 is arc-shaped.
[0027] It should be noted that rotating the adjusting bolt 24 causes one end of the adjusting bolt 24 to screw into the interior of the positioning tube 14, thereby pushing the clamp 25 to move toward the inner center of the positioning tube 14, and then clamping the steel pipe inside the positioning tube 14 from both sides, and positioning the steel pipe in the center of the positioning tube 14, thereby adapting to the spacing adjustment and rotary welding functions of the device.
