Description

Technical Field

[0001] This patent relates to the technical field of pipe alignment tools, and particularly to an overhead pipe gallery pipe alignment tool. Background Art

[0002] An overhead pipe gallery is a corridor for pipes in the air that is erected on the ground or other supports, used to provide support and protection for the pipes so that the pipes can complete the conveying work. Since the pipes required for conveying are relatively long, workers need to align adjacent pipes inside the overhead pipe gallery and then connect them by welding. When aligning the pipes, pipe alignment tools are needed to ensure that the pipes are at the same height and horizontal line.

[0003] The existing pipe alignment tool consists of a walkable bottom plate. Two arc plates are connected to the base through two vertically arranged adjusting rods. When calibrating the same height of two pipes, only need to make the two arc plates at the same height through the adjusting rods, and then place the two pipes inside the two arc plates. However, when adjusting the different distances between the two arc plates, two pipes with different distances cannot be calibrated. For this reason, we propose an overhead pipe gallery pipe alignment tool. Summary of the Invention

[0017] The following will clearly and completely describe the technical solutions in the embodiments of this patent with reference to the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this patent without creative efforts shall fall within the scope of protection of this patent.

[0018] Please refer to Figure 1 、 Figure 2 and Figure 3 This patent provides a technical solution: an overhead pipe gallery pipe alignment tool, which includes a bottom plate 1. Rollers 2 are installed at the four corners of the bottom of the bottom plate 1. Vertical plates 3 are integrally formed on the left and right sides of the top of the bottom plate 1. A circular hole 4 is provided in the middle of the vertical plate 3. A screw rod 5 is rotatably connected in the circular hole 4 through a bearing. Two threads 6 in different directions are respectively provided on the left and right sides of the side wall of the screw rod 5. Nuts 7 are respectively connected to the two threads 6. A limiting slide bar 8 is fixedly installed at the bottom end of the outer side wall of the nut 7. Slide ways 9 are provided on the left and right sides of the top of the bottom plate 1. The bottom end of the limiting slide bar 8 is slidably installed in the slide way 9. An adjusting rod 10 is fixedly installed at the top end of the outer side wall of the nut 7. An arc plate 11 is fixedly installed at the top end of the adjusting rod 10.

[0019] The adjusting rod 10 includes a column 12 and a stud 17. The bottom end of the column 12 is fixedly installed at the top end of the outer side wall of the nut 7. A circular ring 13 is integrally formed at the top end of the column 12. A circular groove 14 is provided at the top of the circular ring 13. A bearing 15 is fixedly installed on the inner side wall of the circular groove 14. The outer side wall of the outer ring of the bearing 15 is fixedly installed on the inner side wall of the circular groove 14. The top end of the inner ring of the bearing 15 is fixedly installed with an internal thread ring 16. The inner side wall of the internal thread ring 16 is screwed with the side wall of the stud 17. A limiting member is provided at the bottom end of the stud 17.

[0020] The setting of the bearing 15 is used to enable the stud 17 to rotate relative to the column 12.

[0021] Specifically, the limiting member includes a square block 18. The top of the square block 18 is fixed to the bottom end of the stud 17. A square groove 19 is provided at the top end of the column 12. The side wall of the square block 18 is relatively fitted and slid with the inner side wall of the square groove 19.

[0022] The limiting member is used to limit the movement track of the stud 17 so that it can only move up and down, avoiding the rotation of the stud 17.

[0023] Specifically, the side wall of the stud 17 does not contact the inner side wall of the square groove 19.

[0024] By the side wall of the stud 17 not contacting the inner side wall of the square groove 19, the wear of the thread on the side wall of the stud 17 can be avoided.

[0025] Specifically, a rectangular hole 20 is provided at the right end of the inner side wall of the square groove 19, and a scale line 21 distributed continuously up and down is provided on the rear inner side wall of the rectangular hole 20.

[0026] The setting of the scale line 21 can calibrate the heights of the two square blocks 18, and further facilitate the calibration of the heights of the two arc plates 11.

[0027] Specifically, the limiting slide bar 8 includes a rod body 22. The top end of the rod body 22 is fixedly installed at the bottom end of the outer side wall of the nut 7. The bottom end of the rod body 22 is fixedly installed with a wheel frame 23. A limiting wheel 24 is rotatably connected to the wheel frame 23 through a pin shaft, and the bottom end of the limiting wheel 24 is rollingly installed in the slideway 9.

[0028] Specifically, the limiting wheel 24 is cylindrical, and the bottom sides of the front and rear sides of the limiting wheel 24 are respectively attached to the front and rear inner side walls of the slideway 9.

[0029] If the bottom end of the rod body directly slides in the slideway 9, the limit is sliding limit and the friction is large. If the limiting wheel 24 is rollingly installed in the slideway 9, the sliding limit part changes to rolling limit, which can reduce the friction, reduce the resistance and facilitate the operation.

[0030] Working principle: The upper side of the pipe gallery can be used to hoist two pipelines respectively through hoisting tools (the upper part of the pipe gallery is in an open state during installation). When the distance between the two pipelines in the pipe gallery becomes larger, the screw rod 5 can be rotated to make the two nuts 7 and the two arc plates 11 move away from each other, which is convenient for the calibration and alignment operation of the two pipelines with different distances, so that the two arc plates 11 move to the distance position of the two pipelines. Then the internal thread ring 16 can be rotated to make the stud 17 drive the arc plate 11 to move up and down until the arc plate 11 moves to the installation height of the pipeline. Then the pipeline is placed in the arc plate 11, and the two pipelines are welded together by welding, and then the pipeline is installed in the pipe gallery.

On the basis of the technical design principle, the settings of the power mechanism, power supply system and control system of the device are not fully described clearly. Under the premise that those skilled in the art understand the principle of the above patent, the specific details of its power mechanism, power supply system and control system can be clearly known.
