DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A clamping structure for clamping the fixed bracket is provided on the processing platform. The parts of the fixed bracket are clamped by the clamping structure, and then the welding of the fixed bracket is facilitated, avoiding the need for multiple people to cooperate to fix the parts during the processing of the fixed bracket, and avoiding the problems of slow welding processing progress and poor welding quality due to fixing problems. The fixed bracket on it is driven to rotate by the rotation of the support cylinder. After welding one side, the processing platform is rotated to continue welding the other side of the fixed bracket, avoiding the back and forth movement of personnel, and improving the processing efficiency during the workpiece welding process.

[0022] Furthermore, if Figure 1 As shown, the lower end of the support cylinder 7 is connected to the support base 1 through a detachable rotating mechanism. After the device is used in one place, it can be disassembled for easy storage and temporary storage for the next use, or transported to another construction site for assembly and continued turnover.

[0023] The detachable rotating mechanism comprises a first rotating structure rotatably arranged on the supporting base 1 , and a clamping structure matching the first rotating structure is arranged at the lower end of the supporting cylinder 7 .

[0024] Embodiment 2 is different from Embodiment 1 in that Figure 4 As shown, the first rotating structure includes a first rotating ring 19 rotatably arranged on the support base 1 and a plurality of sliding blocks 21 slidably arranged on the first rotating ring 19. After the support cylinder 7 can be inserted into the first rotating ring 19, the sliding block 21 is engaged with the support cylinder 7 to prevent the support cylinder 7 from falling off. Among them, a primary groove is provided in the central part of the support base 1, and the lower end of the first rotating ring 19 is rotatably connected in the primary groove through a bearing, and the first rotating ring 19 extends upward. The sliding block 21 is slidably arranged in the middle part of the first rotating ring 19, and the sliding block 21 can extend out of the inner ring surface of the first rotating ring 19. At least two sliding blocks 21 are evenly distributed in the circumferential direction of the first rotating ring 19.

[0025] Among them, a transverse sliding groove is provided on the first rotating ring 19, which slides with the sliding block 21, so that the sliding block 21 can slide out of the side of the first rotating ring 19 and then engage with the clamping structure on the supporting cylinder 7, or retract into the transverse sliding groove after disengaging from the clamping structure; and the inner end of the sliding block 21 is connected to the inner end of the transverse sliding groove through a spring 25.

[0026] Furthermore, if Figure 6As shown, the clamping structure includes a plurality of third grooves 28 arranged on the side surface of the lower end of the support cylinder 7 and matched with the sliding block 21, and the third grooves 28 are circumferentially arranged on the outer periphery of the lower end of the support cylinder 7 around the axis of the support cylinder 7. In this embodiment, four third grooves 28 and four sliding blocks 21 are provided, and the positions of the third grooves 28 and the sliding blocks 21 correspond one to one. In other embodiments, two, three, five, or six third grooves 28 and sliding blocks 21 may be provided.

[0027] Furthermore, the first rotating ring 19 is provided with a vertical slide groove, the lower end of which is cross-connected with the horizontal slide groove; a button 20 is slidably provided in the vertical slide groove, and the upper end of the button 20 is exposed from the upper surface of the first rotating ring 19, such as Figure 4 The lower end of the button 20 is provided with an inclined surface that slides with the inner end of the sliding block 21 and is used to push the sliding block 21 outward. Figure 5 As shown, the inner end of the sliding block 21, that is, the end of the sliding block 21 that is always located in the transverse slide groove, is provided with an upper inclined surface extending outwardly and upwardly from the end surface of the sliding block 21, that is, one end of the upper inclined surface is located at the lower part of the inner end surface of the sliding block 21, and the other end is located at the upper side of the sliding block 21. The lower end of the button 20 is provided with a lower inclined surface extending outwardly and upwardly from the lower end surface, that is, one end of the lower inclined surface is located at the lower end of the button 20, and the other end is located at the side of the button 20 facing the sliding block 21. Therefore, after the button 20 is pressed and moved downward, the lower inclined surface squeezes the upper inclined surface and slides with the upper inclined surface, so that the sliding block 21 moves outward, so that the outer end of the sliding block 21 enters the third groove 28 of the supporting cylinder 7.

[0028] like Figure 5As shown, the lower end of the button 20 is provided with a button slot 201, and the inner end of the sliding block 21 is provided with a protrusion that can be inserted into the button slot 201, and the protrusion is slidably matched with the button slot 201. Specifically, a rectangular protrusion extending inwardly and laterally is provided in the middle of the inner end of the sliding block 21, and the above-mentioned upper inclined surfaces are provided on both sides of the protrusion. Correspondingly, the button slot 201 is provided at the position of the rectangular protrusion in the middle of the lower end of the button 20, and the above-mentioned lower inclined surfaces are provided at the corresponding positions on both sides of the button slot 201. The button slot 201 has a certain height, so that when the button 20 is pressed downward to drive the lower inclined surface and the upper inclined surface to slide relative to each other, the rectangular protrusion of the sliding block 21 gradually slides from the lower part of the button slot 201 into the upper part of the button slot 201, until the upper inclined surface and the lower inclined surface are separated, and the inner end of the button 20 is pressed against the side surface of the lower part of the button 20. A vertical end face is provided at the inner end of the sliding block 21, that is, a vertical end face is provided at the lower end of the upper inclined surface, so that the end face is pressed against the side of the button 20 to prevent the sliding block 21 from being separated from the third groove 28. At this time, the upper end of the button 20 is still exposed from the upper surface of the first rotating ring 19, so that the sliding block 21 is separated from the third groove 28 after the button 20 is pushed upward, thereby achieving the purpose of disassembling the connection between the support cylinder 7 and the support base 1.

[0029] Furthermore, a protrusion extending laterally may be provided on one side of the upper end of the button 20 to facilitate pushing the button 20 upward, thereby allowing the sliding block 21 to return to its original position and slide out of the third groove 28 .

The opening of the first groove 26 faces downward, so as to be conveniently sleeved on the plug-in block 22. If the plug-in block 22 is rotationally symmetrically arranged around the rotation axis of the second rotating ring 24, the first groove 26 is rotationally symmetrically arranged around the axis of the support cylinder 7.

The rotation can be automatically controlled, and there is no need to manually rotate the workpiece, which improves the processing efficiency.

[0039] Step 3: top structure installation; Thread the connecting plate 8 onto the top of the supporting cylinder 7 (the direction in which the supporting cylinder 7 is rotated and tightened relative to the connecting plate 8 is consistent with the direction in which the supporting cylinder 7 rotates under the drive mechanism). Adjust the right channel steel 9 and the left channel steel 10 to a suitable length, and respectively open a first clamping groove 17 and a second clamping groove 18 on the right channel steel 9 and the left channel steel 10.

Then rotate the connecting plate 180°, and weld the other of the right channel steel 9 and the left channel steel 10 perpendicularly to the connecting plate 8 to the other end of the connecting plate 8, thereby initially forming a processing platform.

[0041] Finally, another pair of angle steels are symmetrically arranged, and the pair of angle steels are connected to the left channel steel 10 after passing the bolts through the second clamping groove 18 of the left channel steel 10. Then the processing platform is rotated 180°, and the other end of the pair of angle steels is passed through the first clamping groove 17 of the right channel steel 9, and connected to the right channel steel 9 to form a set of clamping grooves.
