DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the patent will be described clearly and completely below with reference to the drawings in the embodiments of the patent. Obviously, the described embodiments are only part of the embodiments of the patent, not all the embodiments. Based on the embodiments in the patent, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the patent.

[0019] Please refer to Figure 1 and Figure 2 The patent provides a technical solution: a portable steel pipe welding support, comprising a base 1, and support plates 4 are mounted on the top of the base 1 left and right sides;

[0020] The base 1 comprises a first plate body 2 and a second plate body 3, the right end top of the first plate body 2 and the left end top of the second plate body 3 are hingedly connected by a hinge, and the top of the first plate body 2 and the top of the second plate body 3 are each provided with a square groove;

[0021] The middle part of the bottom of the support plate 4 is provided with a threaded groove 7, a stud 8 is screwed in the threaded groove 7, the bottom end of the stud 8 is integrally formed with a square column 9, the shape and size of the square column 9 match the shape and size of the inside of the square groove, and the square column 9 is inserted into the square groove;

[0022] The middle part of the support plate 4 is provided with a circular hole 5, the inner side wall top of the circular hole 5 is provided with a mounting groove 10, the top of the mounting groove 10 is provided with a threaded hole 11, a bolt 12 is screwed in the threaded hole 11, a spring 14 is sleeved on the side wall of the bolt 12, the bottom end of the spring 14 is fixedly installed with a pressing plate 13, the left and right ends of the pressing plate 13 are integrally formed with a sliding block 15, and the left and right ends of the inner side wall of the mounting groove 10 are each provided with a sliding groove 16. The sliding block 15 is slidingly installed in the sliding groove 16.

[0023] The sliding block 15 is slidingly installed in the sliding groove 16, which is used to limit the movement trajectory of the pressing plate 13, so that it can only move up and down.

[0024] Specifically, the end head side wall of the bolt 12 is fixedly installed with a gear 17.

[0025] The two gears 17 on the two bolts 12 can be engaged with a rack respectively. Figure 1 When the rack is pushed, the two bolts 12 can be controlled to rotate at the same time, thereby facilitating the control of the two pressing plates 13.

[0026] Specifically, the top of the support plate 4 is fixedly installed with a fixed plate 18, and the front side of the fixed plate 18 is provided with a rectangular groove 19.

[0027] The upper and lower widths of the rectangular groove 19 match the upper and lower widths of the rack to be used, and when the rack is placed in the rectangular groove 19 and then moved to the front side, the teeth on the front side of the rack can be engaged with the two gears 17, which is used to limit the movement trajectory of the rack.

[0028] The height of the rack needs to be greater than the height of the gear 17, so as to adapt to the change in height when the gear 17 rotates.

[0029] Specifically, the bottom of the pressing plate 13 is provided with an arc-shaped groove 20.

[0030] The arc-shaped groove 20 matches the arc of the outer side wall of the steel pipe to be clamped and welded, which can increase the pressing area and thus increase the pressing force.

[0031] Specifically, the inner side wall of the circular hole 5 is provided with an annular groove 6.

[0032] The annular groove 6 can reduce the contact area between the steel pipe and the inner side wall of the circular hole 5, reduce the hindering effect, and facilitate the insertion of the steel pipe into the circular hole 5.

[0033] Specifically, the support plate 4 includes an upper plate body 21 and a lower plate body 22, the bottom of the upper plate body 21 and the top of the lower plate body 22 are relatively combined, mounting rings are arranged at the front and rear ends of the upper plate body 21 and the lower plate body 22, mounting bolts are arranged in the mounting rings, and nuts are screwed with the bottom ends of the mounting bolts through the two mounting rings.

[0034] By dividing the support plate 4 into two parts of the upper plate body 21 and the lower plate body 22, the annular groove 6 can be divided into two parts, which facilitates the opening of the annular groove 6 and the mounting groove 10 in the early stage.

[0035] Specifically, the bottom end of the bolt 12 can be provided with a spherical surface.

[0036] The spherical surface can reduce the contact area between the bottom end of the bolt 12 and the top of the pressing plate 13, reduce the damping effect, and further increase the sliding effect of the contact surface when the bolt 12 rotates.

[0037] Working principle: when in use, the two steel pipes to be welded are inserted into the two circular holes 5 respectively, and the welding ends are combined together, the bolt 12 is rotated, the pressing plate 13 is driven downward by the bolt 12, the spring 14 is stretched and elongated, the steel pipes are fixed by the arc-shaped groove 20 pressing on the outer side wall of the steel pipes, then the welding ends of the two steel pipes are welded together, after welding is completed, the bolt 12 is reversely rotated to move upward, the pressing plate 13 is separated from the steel pipes by the rebound effect of the spring 14, and the steel pipes can be extracted.

[0038] When transporting and carrying, the support plate 4 can be disassembled from the first plate body 2 and the second plate body 3 by moving the support plate 4 upward to make the square column 9 disengage from the square groove, then rotating the square column 9 to make the stud 8 disengage from the threaded groove 7 to ensure the flatness of the bottom of the support plate 4, and the bottom of the support plate 4 is placed in the carriage of the transport vehicle, and the first plate body 2 and the second plate body 3 are folded through the hinged position, the whole support can be disassembled through the above structure, the occupied space is small, and the transportation and carrying of the steel pipe welding frame are facilitated.
