Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a tie-and-install auxiliary device. Background Art

[0002] Steel structure grid systems are mostly used in buildings such as airports, gymnasiums, and factories. During the grid assembly process, some rods need to be butt-welded due to construction technology or methods. However, since most welding operations are done at high altitudes and the rods are heavy, it is difficult to ensure that the axis lines of the two butted rods are in the same straight line during the butt welding process. Therefore, an auxiliary welding device is needed, which is more widely used.

[0003] For example, the authorization announcement number is "CN220145089U", which is a tie-and-install auxiliary device. The length of the first rotating block and the second rotating block are adjusted to adapt to the length of the pipe fitting, and the first clamp is fixed to one pipe fitting, and the second clamp is fixed to another pipe fitting, and the first rotating block and the second rotating block are rotated to drive the two pipe fittings to rotate. Under the action of the support spring, the first connecting plate and the second connecting plate are tightened and the two fixed pipe fittings are ensured to be in the same straight line, and then the docking positions of the two pipe fittings are welded and fixed, which is convenient to use. However, in the above method, the spacing of the pipe fittings is adjusted by the relative movement of the two telescopic rods. Since the telescopic rods generally require a complete set of braking systems such as hydraulic starting systems, electric drives, etc. when in use, the working cost is relatively high. At the same time, the pipe fittings are limited by the clamps in the above method. Since the clamps are fixed in size and are only applicable to pipe fittings of the same thickness, they are highly limited. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that a complete braking system, such as a hydraulic starting system, an electric drive, etc., is generally required for a telescopic rod when in use, which results in a high working cost. At the same time, the pipe fitting is limited by a clamp in the above-mentioned method. Since the clamp has a fixed size and is only applicable to pipe fittings of the same thickness, it has a high limitation. Therefore, a tie-and-install auxiliary device is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tie-fastening installation auxiliary device is designed, including a first transverse plate and a second transverse plate, a straight rod is fixedly connected to the right side of the outer wall of the first transverse plate, the outer wall of the straight rod is slidably connected to the second transverse plate, an auxiliary spacing adjustment structure for tie-fastening installation is provided at the upper end of the outer wall of the second transverse plate, two concave plates are fixedly connected to the lower ends of the outer walls of the first and second transverse plates, a plurality of the outer walls of the concave plates are fixedly connected to clamps, a plurality of the outer walls of the clamps are fixedly connected to belts, and a plurality of the outer walls of the clamps are provided with auxiliary limiting structures for tie-fastening installation.

[0007] Preferably, the tie-knot installation auxiliary spacing adjustment structure includes an outer shell, the inner wall of the outer shell is threadedly connected to the threaded rod through a bearing, the right end of the outer wall of the threaded rod is fixedly connected with a handle, the outer wall of the threaded rod is threadedly connected to the threaded seat, the threaded seat is slidably connected to the inner wall of the outer shell, and the lower end of the outer wall of the threaded seat is fixedly connected to the upper end of the outer wall of the first horizontal plate.

[0008] Preferably, a plurality of through holes are processed on the plurality of belts, and the lower end of the outer wall of the outer shell is fixedly connected to the upper end of the outer wall of the second transverse plate.

[0009] Preferably, the two left-end clamps and belts are in contact with the outer wall of the first pipe, and the two right-end clamps and belts are in contact with the outer wall of the second pipe.

[0010] Preferably, the plurality of tie-anchor installation auxiliary limiting structures include a box body, two springs are arranged on the inner wall of the box body, the two sides of the springs are respectively fixedly connected to the vertical plate and the box body, the left end of the outer wall of the vertical plate is fixedly connected with a pull rod, the pull rod passes through the box body, the outer wall of the pull rod is slidably connected to the box body, two cross bars are fixedly connected to the right side of the outer wall of the vertical plate, a flat plate is fixedly connected to the middle part of the inner wall of the box body, the two cross bars pass through the flat plate, and the outer walls of the two cross bars are slidably connected to the flat plate.

[0011] Preferably, the plurality of belts respectively pass through openings processed on the surface of the second box body, and the outer walls of the plurality of cross bars are plugged into the through holes processed on the belts.

[0012] The utility model proposes a tie-and-install auxiliary device, the beneficial effect of which is that through the cooperation of the tie-and-install auxiliary limiting structure and the clamp, the vertical plate is pulled to move to the left in the first box body to compress the two springs, and the vertical plate moves to the left to drive the two cross bars to slide to the left in the flat plate, so that the two cross bars are pulled out of the through holes processed on the belt, and then the belt is pulled upward to make the outer wall of the belt close to the outer wall of the first pipe fitting, and then the pull rod is loosened to drive the flat plate to reset through the two springs, such as driving the two cross bars through the flat plate to insert the belt into the through holes corresponding to the belt to limit the position of the belt and thereby also limit the first pipe fitting, and utilizing the tie-and-install auxiliary limiting structure to drive the first cross plate to move, so that the limited first pipe fitting is moved closer to the second pipe fitting to adjust the spacing, thereby avoiding the prior art of adjusting the spacing of the pipe fittings through the relative movement of the two telescopic rods, because the telescopic rod generally requires a complete braking system such as a hydraulic starting system, an electric drive, etc. when in use, thereby reducing the working cost.

[0013] By pulling and installing the auxiliary spacing adjustment structure and the cooperation of the first horizontal plate and the second horizontal plate, turning the handle drives the threaded rod to rotate through the bearing in the shell. The rotation of the threaded rod drives the threaded seat to slide to the right in the slide groove processed on the inner wall of the shell. The sliding right of the threaded seat drives the first horizontal plate to move to the right, so that the limited first pipe fitting moves closer to the second pipe fitting. The pipe fitting is limited by pulling the belt, which is suitable for use with pipe fittings of different thicknesses and reduces limitations. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See attached Figure 1-4 : Multiple tie-installation auxiliary limiting structures 2 include a box body 201, two springs 202 are arranged on the inner wall of the box body 201, and the two sides of the spring 202 are respectively fixedly connected to the vertical plate 203 and the box body 201, and the elastic coefficients of the two springs 202 can meet the work needs according to the actual needs, and the left end of the outer wall of the vertical plate 203 is fixedly connected with a pull rod 205, and the pull rod 205 runs through the box body 201;

[0028] Working principle:

[0029] Auxiliary welding limit work for tie-in installation of pipe fittings:

[0030] When the pipe fittings need to be welded using a tie-in installation aid, the first pipe fitting 6 is placed between the two left-end clamps 9 and the belt 11, and then the pull 205 drives the vertical plate 203 to move leftward in the first box 201 to compress the two springs 202 (such as Figure 4), the vertical plate 203 moves to the left and drives the two cross bars 206 to slide to the left in the flat plate 204, so that the two cross bars 206 are pulled out from the through holes 10 processed on the belt 11, and then the belt 11 is pulled upward to make the outer wall of the belt 11 close to the outer wall of the first pipe 6, and then the pull rod 205 is loosened to drive the flat plate 203 to reset through the two springs 202, so that the two cross bars 206 can be driven by the flat plate 203 to insert the belt 11 and the corresponding through holes 10 to limit the position of the belt 11 and thus also limit the first pipe 6. Since the auxiliary limiting structure 2 for the tie-in installation is provided with multiple structures that are the same as the above-mentioned movement, the first pipe 6 and the second pipe 7 are limited in sequence (the second pipe 7 is placed between the two clamps 9 at the right end and the belt 11).
