TECHNICAL FIELD

[0001] The application relates to the technical field of steel pipe truss, in particular to a steel pipe truss machine for metal scaffolding. BACKGROUND

[0002] A truss is a structure with a constant geometric shape composed of triangular frames formed by straight bars, and the junctions between the bars are called nodes. According to the axis of the truss bars and the distribution of external forces, the truss can be divided into plane trusses and space trusses. Space structures such as roof trusses and bridges are composed of a series of parallel plane trusses. If they mainly bear plane loads, they can be simplified as plane trusses for calculation.

[0003] In the production process of the existing scaffolding, workers usually cut steel pipes into the required length first, and then manually weld or manually rotate bolts to splice into a truss structure. The whole production process not only brings great labor intensity to the workers, but also has low production efficiency and poor quality. The whole operation process is not only cumbersome, but also prone to problems such as unstable welding and structural deformation, which affects the construction safety and service life. Therefore, we propose a steel pipe truss machine for metal scaffolding. SUMMARY

[0053] The vertical and horizontal assembly assembly 9 includes a cutting member 12 arranged above the bottom plate 1, which drives the plurality of pipe cutting circular knives 8 to rotate and lift, and drives the plurality of pipe cutting circular knives 8 to cut the two ends of the adjacent horizontal pipe 3; The bottom plate 1 is provided with a turnover member 13, which drives the horizontal pipe 3 to move between the two vertical pipes 2 after cutting, the bottom plate 1 is provided with a rotating member 14, which drives the plurality of vertical pipes 2 to rotate, so that the rotated vertical pipe 2 enters different processing stations, and the bottom plate 1 is provided with a drilling member 15, which drills holes in the two ends of the vertical pipe 2.

[0054] The cutting member 12 comprises a cutting frame 121 arranged on the bottom plate 1, four lifting grooves 122 are arranged on the cutting frame 121, a rectangular rod 123 matched with the lifting grooves 122 is slidably arranged in each of the four lifting grooves 122, a cutting motor 124 is arranged at the opposite end of each of the four rectangular rods 123, four cutting pipe circular knives 8 are arranged at the output ends of the four cutting motors 124 respectively, lifting rods 125 are slidably arranged on both sides of the cutting frame 121, the opposite ends of the four rectangular rods 123 are arranged in the adjacent lifting rods 125 respectively, two cutting electric push rods 126 are arranged on the bottom plate 1, the bottom ends of the two lifting rods 125 are arranged at the output ends of the two cutting electric push rods 126 respectively, when the cross pipe 3 is clamped by the first clamp plate 137 and the second clamp plate 139, the two cutting electric push rods 126 are started at the same time, the two cutting electric push rods 126 will pull down the lifting rods 125, the downward moving lifting rods 125 will drive the corresponding rectangular rods 123 to move downward, so that the rectangular rods 123 slide in the lifting grooves 122, at this time, the four cutting motors 124 are started, the cutting motors 124 will drive the cutting pipe circular knives 8 at the output ends to rotate, with the descending of the rectangular rods 123, the cutting pipe circular knives 8 gradually cut into the cross pipe 3, realizing the accurate cutting of the cutting pipe circular knives 8 on both ends of the cross pipe 3, after the cutting is completed, the four cutting motors 124 are automatically stopped, the lifting rods 125 are lifted back, and the rectangular rods 123 are reset, which ensures that the cutting surfaces of both ends of the cross pipe 3 are flat, improves the assembly precision, reduces the subsequent welding error, ensures the stability of the scaffold structure, and prolongs the service life.

[0055] The turnover member 13 comprises a turnover frame 131 arranged on the bottom plate 1, two turnover rods 132 are rotatably arranged on the turnover frame 131, two turnover plates 133 are equidistantly arranged on the outer sides of the two turnover rods 132 respectively, and first telescopic frames 134 are arranged on both sides of the four turnover plates 133;

[0056] Second telescopic frames 135 are slidably arranged in the first telescopic frames 134, telescopic springs 136 are arranged between the first telescopic frames 134 and the second telescopic frames 135, first clamp plates 137 are arranged at the ends of the second telescopic frames 135 away from the telescopic springs 136, clamp shafts 138 are rotatably arranged in the first clamp plates 137, second clamp plates 139 are arranged on the outer sides of the clamp shafts 138, turnover torsional springs 1310 are arranged on the outer sides of the clamp shafts 138, the first clamp plates 137 close to the four cutting pipe circular knives 8 are located at the bottom of the cross pipe 3, and the first clamp plates 137 away from the four cutting pipe circular knives 8 are located at the top of the cross pipe 3;

[0057] The two turnover levers 132 are provided with turnover gears 1311 on the outer sides. One of the two turnover levers 132 is provided with a turnover motor 1312 at one end. The turnover frame 131 is provided with an auxiliary gear 1313 on the side close to the turnover motor 1312 through a rotating shaft. The auxiliary gear 1313 is engaged with an adjacent turnover gear 1311. The auxiliary gear 1313 and the other turnover gear 1311 are provided with a turnover belt 1314 on the outer sides. The turnover belt 1314 is provided with a plurality of turnover tooth grooves 1315 which are engaged with the auxiliary gear 1313 and the other turnover gear 1311. The cross pipe 3 is placed between the first clamp plate 137 and the second clamp plate 139 on the side close to the pipe cutting circular knife 8, so that the cross pipe 3 presses the first clamp plate 137 and the second clamp plate 139. When the first clamp plate 137 and the second clamp plate 139 are pressed by the cross pipe 3, the second clamp plate 139 rotates through the clamp shaft 138. At this time, the turnover torsional spring 1310 on the outer side of the clamp shaft 138 starts to store energy. After the cross pipe 3 completely enters between the first clamp plate 137 and the second clamp plate 139, the turnover torsional spring 1310 releases energy to drive the second clamp plate 139 to quickly clamp the cross pipe 3, so as to ensure that the cross pipe 3 is stably positioned and facilitate subsequent pipe cutting operation. After the cross pipe 3 is clamped by the first clamp plate 137 and the second clamp plate 139, two cutting electric push rods 126 are started at the same time. The two cutting electric push rods 126 pull down the lifting rod 125. The lifting rod 125 moving downward drives the corresponding rectangular rod 123 to move downward, so that the rectangular rod 123 slides in the lifting groove 122. At this time, four cutting motors 124 are started. The cutting motor 124 drives the pipe cutting circular knife 8 at the output end to rotate. With the descent of the rectangular rod 123, the pipe cutting circular knife 8 gradually cuts into the cross pipe 3, so as to realize accurate cutting of the cross pipe 3 at both ends by the pipe cutting circular knife 8. After cutting is completed, the four cutting motors 124 are automatically stopped, the lifting rod 125 is lifted back, and the rectangular rod 123 is reset. After the cutting of the cross pipe 3 is completed, the turnover motor 1312 is started. The turnover motor 1312 drives one of the turnover levers 132 at the output end to rotate. When the turnover lever 132 rotates, the turnover gear 1311 provided at one end of the turnover lever 132 also rotates, so as to drive the auxiliary gear 1313 engaged with the turnover gear 1311 at the output end of the turnover motor 1312 to rotate. When the auxiliary gear 1313 rotates, the turnover belt 1314 provided on the outer side of the auxiliary gear 1313 drives one of the turnover gears 1311 above the auxiliary gear 1313 to rotate through the plurality of turnover tooth grooves 1315, so as to make the two turnover gears 1311 synchronously and reversely rotate. When the two turnover gears 1311 synchronously and reversely rotate, the corresponding turnover levers 132 also synchronously and reversely rotate, so as to make the turnover plates 133 on the outer sides of the two turnover levers 132 synchronously and reversely rotate. While the turnover plates 133 rotate, the first telescopic plates provided on both sides of the turnover plates 133 also rotate with the turnover plates 133.Thus, the corresponding second telescopic plate is synchronously and reversely rotated, so that the second telescopic plate drives the horizontal pipe 3 with both ends cut to rotate through the first clamp plate 137 and the second clamp plate 139. When the horizontal pipe 3 rotates 180°, the turnover motor 1312 is turned off, so that the turnover plate 133 stops rotating, and the horizontal pipe 3 is stably turned over to a predetermined position, facilitating the next operation of the worker. Its role is to ensure that the cut horizontal pipe 3 can reach the side close to the vertical pipe 2 through accurate turnover and positioning, facilitate the butt joint of the vertical pipe 2 and the horizontal pipe 3, reduce the manual adjustment time, improve the assembly efficiency, and reserve a horizontal pipe 3 feeding station through another first clamp plate 137 and second clamp plate 139. It ensures that the worker can still perform the feeding and discharging operation of the horizontal pipe 3 before the butt joint of the cut horizontal pipe 3, ensures the continuity of the production process, avoids the efficiency loss caused by waiting, and further improves the automation level and working efficiency of the whole assembly line.

[0058] The rotating member 14 comprises a rotating frame 141 arranged on the bottom plate 1, and the rotating frame 141 is provided with a rotating motor 142 on the top. The output end of the rotating motor 142 is provided with an adjusting gear 143, and the rotating frame 141 is rotatably provided with two rotating shafts 144. The outer sides of the two rotating shafts 144 are provided with rotating gears 145. Among the two rotating gears 145, one rotating gear 145 close to the adjusting gear 143 is engaged with the adjusting gear 143, and the other rotating gear 145 is provided with a rotating belt 146 outside the adjusting gear 143. The rotating belt 146 is provided with a plurality of rotating tooth grooves 147 engaged with the adjusting gear 143 and the rotating gear 145.

After the staff places the horizontal pipe 3 on the first clamp plate 137 and the second clamp plate 139, the staff places the vertical pipe 2 in the rotating groove 1410 formed in the rotating wheel 149, and makes the top of the vertical pipe 2 adhere to the circular magnet plate 1411 in the top plate 148. The circular magnet plate 1411 generates strong adsorption force, firmly fixes the vertical pipe 2, and prevents sliding. Then the rotating motor 142 is started, which drives the adjusting gear 143 at the output end to rotate. When the adjusting gear 143 rotates, one rotating gear 145 engaged with the adjusting gear 143 rotates in the opposite direction synchronously with the adjusting gear 143, and the rotating belt 146 arranged on the outer side of the adjusting gear 143 drives one rotating gear 145 away from the rotating motor 142 to rotate synchronously through a plurality of rotating gear grooves 147, so that the two rotating gears 145 rotate in the opposite direction synchronously. When the two rotating gears 145 rotate in the opposite direction synchronously, the rotating shaft 144 arranged at the axis of the two rotating gears 145 rotates synchronously with the corresponding rotating gear 145, so that the rotating shaft 144 drives the top plate 148 at the bottom to rotate. When the two top plates 148 rotate in the opposite direction synchronously, the circular magnet plate 1411 arranged on the inner side of the top plate 148 also rotates synchronously, ensuring that the vertical pipe 2 remains stable during rotation and avoids any deviation or shaking, thereby ensuring accurate positioning and safe operation of the vertical pipe 2 during processing. At this time, the rotating wheel 149 arranged at the bottom of the top plate 148 is driven by the rotating shaft 144 to rotate in the opposite direction synchronously, so that the two rotating wheels 149 drive the vertical pipe 2 to rotate smoothly until the vertical pipe 2 rotates 120° around the rotating shaft 144 and reaches the side of the vertical plate 152. The purpose is to accurately control the rotation angle, ensure that the vertical pipe 2 reaches the drilling station, and then enable the drilling bit 156 to accurately process the reserved holes at both ends of the vertical pipe 2, ensuring that the hole positions are symmetrical and have no deviation, improving the stability and service life of the overall structure, achieving efficient and accurate processing, and ensuring that each part can be accurately connected during subsequent assembly, avoiding structural looseness or deformation caused by hole position errors, further improving the firmness and safety of overall assembly, and ensuring long-term stable operation of the equipment.

As the vertical plate 152 approaches the longitudinal pipe 2, the rubber pad 154 in the recess of the Y-shaped plate 153 gradually adheres to the surface of the longitudinal pipe 2 to provide stable support and prevent vibration during drilling. When the rubber pad 154 contacts the longitudinal pipe 2, the drilling drill bit 156 starts to contact the surface of the longitudinal pipe 2.

[0066] In use, when the worker needs to assemble the scaffold, the cross pipe 3 is placed between the first jaw plate 137 and the second jaw plate 139 on the side close to the pipe cutting circular knife 8, so that the cross pipe 3 extrudes the first jaw plate 137 and the second jaw plate 139, when the first jaw plate 137 and the second jaw plate 139 are extruded by the cross pipe 3, the second jaw plate 139 will rotate through the jaw shaft 138, at this time the flip torsional spring 1310 outside the jaw shaft 138 starts to store energy, when the cross pipe 3 completely enters between the first jaw plate 137 and the second jaw plate 139, the flip torsional spring 1310 releases energy, driving the second jaw plate 139 to quickly clamp the cross pipe 3, ensuring that the cross pipe 3 is stably positioned, facilitating subsequent pipe cutting operation, when the cross pipe 3 is clamped by the first jaw plate 137 and the second jaw plate 139, two cutting electric push rods 126 are started at the same time, the two cutting electric push rods 126 will pull down the lifting rod 125, the downward moving lifting rod 125 will drive the corresponding rectangular rod 123 to move downward, so that the rectangular rod 123 slides in the lifting groove 122, at this time, four cutting motors 124 are started, the cutting motor 124 will drive the cutting pipe circular knife 8 at the output end to rotate, with the descent of the rectangular rod 123, the cutting pipe circular knife 8 gradually cuts into the cross pipe 3, realizing the accurate cutting of the cutting pipe circular knife 8 on both ends of the cross pipe 3, after cutting is completed, the four cutting motors 124 automatically stop, the lifting rod 125 rises back, and the rectangular rod 123 resets, after completing the cutting of the cross pipe 3, the flip motor 1312 is started, the flip motor 1312 will drive a flip rod 132 at the output end to rotate, when the flip rod 132 rotates, the flip gear 1311 arranged at one end of the flip rod 132 will rotate accordingly, so that the flip gear 1311 at the output end of the flip motor 1312 drives the auxiliary gear 1313 meshing therewith to rotate, when the auxiliary gear 1313 rotates, the flip belt 1314 arranged outside the auxiliary gear 1313 will drive a flip gear 1311 located above the auxiliary gear 1313 to rotate through the plurality of flip tooth grooves 1315, so that the two flip gears 1311 synchronously reverse rotate, when the two flip gears 1311 synchronously reverse rotate, the flip rods 132 corresponding thereto also synchronously reverse rotate, so that the flip plates 133 outside the two flip rods 132 synchronously reverse rotate, the first extension plates arranged on both sides of the flip plate 133 rotate with the flip plate 133 at the same time, thereby driving the corresponding second extension plates to synchronously reverse rotate, so that the second extension plates drive the cross pipe 3 cut at both ends through the first jaw plate 137 and the second jaw plate 139 to rotate, when the cross pipe 3 rotates 180°, the flip motor 1312 is turned off, so that the flip plate 133 stops rotating, the cross pipe 3 is stably flipped to the predetermined position, facilitating the next step operation of the worker;

[0067] After the staff places the horizontal pipe 3 on the first clamp plate 137 and the second clamp plate 139, the staff places the vertical pipe 2 in the rotating groove 1410 of the rotating wheel 149, and the top of the vertical pipe 2 is attached to the circular magnet plate 1411 in the top plate 148. The circular magnet plate 1411 generates strong adsorption force to firmly fix the vertical pipe 2 and prevent it from sliding. Then, the rotating motor 142 is started, which drives the adjusting gear 143 at the output end to rotate. When the adjusting gear 143 rotates, a rotating gear 145 engaged with it rotates in the opposite direction synchronously. The rotating belt 146 outside the adjusting gear 143 drives a rotating gear 145 away from the rotating motor 142 to rotate synchronously, so that the two rotating gears 145 rotate in opposite directions synchronously. When the two rotating gears 145 rotate in opposite directions synchronously, the rotating shaft 144 arranged at the axis of the two rotating gears 145 rotates synchronously with the corresponding rotating gear 145, so that the rotating shaft 144 drives the top plate 148 at the bottom to rotate. When the two top plates 148 rotate in opposite directions synchronously, the circular magnet plate 1411 inside the top plate 148 also rotates synchronously, ensuring that the vertical pipe 2 remains stable during rotation and avoids any deviation or shaking, thereby ensuring accurate positioning and safe operation of the vertical pipe 2 during processing. At this time, the rotating wheel 149 arranged at the bottom of the top plate 148 is driven by the rotating shaft 144 to rotate in the opposite direction synchronously, so that the two rotating wheels 149 drive the vertical pipe 2 to rotate smoothly until the vertical pipe 2 rotates 120° around the rotating shaft 144 to reach the side of the vertical plate 152.

[0068] When the vertical pipe 2 reaches the side of the vertical plate 152, the drilling electric push rod 151 is started to move the vertical plate 152 towards the rotated vertical pipe 2. At the same time, the drilling motor 155 is started to rotate the drilling drill bit 156 at the output end. As the vertical plate 152 approaches the vertical pipe 2, the rubber pad 154 in the recess of the Y-shaped plate 153 gradually adheres to the surface of the vertical pipe 2, providing stable support to prevent vibration during drilling. When the rubber pad 154 contacts the vertical pipe 2, the drilling drill bit 156 begins to contact the surface of the vertical pipe 2. As the vertical plate 152 continues to approach, the rubber pad 154 generates greater friction after being squeezed, ensuring that the vertical pipe 2 is stable and immovable. The drilling drill bit 156 gradually penetrates and accurately drills a hole at the predetermined position. The entire process is smooth and efficient, avoiding any deviation and ensuring the processing quality. After completing the drilling work, the drilling electric push rod 151 slowly retreats, and the vertical plate 152 returns to its original position. The rubber pad 154 releases the pressure. Then, the rotating motor 142 is continued to be started to rotate the vertical pipe 2 by 120° to the next predetermined position. It should be noted that please refer to the drawings in the specification Figure 12, three rotating grooves 1410 on the rotating wheel 149 correspond to three workstations respectively, the three workstations are respectively a feeding workstation, a drilling workstation and an assembling workstation, with the longitudinal pipe 2 completing the drilling work continuing to rotate 120°, reaching the assembling workstation, in the process of reaching the assembling workstation, two longitudinal pipes 2 will gradually contact the two ends of the horizontal pipe 3 after cutting in the rotating process, and are automatically clamped by the arc on the surface, ensuring that the horizontal pipe 3 and the longitudinal pipe 2 are tightly fitted, when the two longitudinal pipes 2 and the two ends of the horizontal pipe 3 are fitted, with the rotation of the two longitudinal pipes 2, the horizontal pipe 3 is gradually pulled by the two longitudinal pipes 2, at this time, the second telescopic frame 135 slides in the first telescopic frame 134, and the telescopic spring 136 starts to store energy after being pulled, when the two ends of the horizontal pipe 3 are completely clamped between the two longitudinal pipes 2, the first clamp plate 137 and the second clamp plate 139 still continue to clamp the horizontal plate, the purpose is to ensure that the distance between the two horizontal pipes 3 does not change, which is convenient for subsequent welding and shaping, when the two ends of the horizontal pipe 3 are completely clamped between the two longitudinal pipes 2, the welding robot 7 is started, the welding robot 7 accurately moves to the predetermined position, starts the welding program, the high-temperature welding gun is aligned with the joint of the horizontal pipe 3 and the longitudinal pipe 2, the metal is instantaneously melted and a firm weld is formed, the welding robot 7 here is prior art, which will not be described in detail here;

[0069] After the welding is completed, the welding robot 7 automatically returns to the original position, and then the traction electric push rod 113 on both sides of the conveying belt 111 is started. The traction electric push rod 113 will push the traction plate 114 at the output end to the direction of the horizontal pipe 3 until the inclined surface of the inclined edge plate 115 is in contact with the welded horizontal pipe 3. At this time, the traction electric push rod 113 continues to push the traction plate 114, and the inclined edge plate 115 will be extruded by the horizontal pipe 3. When the inclined edge plate 115 is extruded, the inclined edge plate 115 will slide into the traction plate 114 until the inclined edge plate 115 is completely embedded in the traction plate 114. At this time, the first traction spring 116 in the inclined edge plate 115 starts to store energy. With the continuous movement of the traction plate 114, the inclined edge plate 115 passes over the horizontal pipe 3, and the inclined edge plate 115 is quickly reset and pops out under the action of the first traction spring 116. At this time, the four inclined edge plates 115 are clamped on the opposite sides of the two horizontal pipes 3 respectively under the cooperation of the traction plate 114, and then the traction electric push rod 113 is started to pull back the traction plate 114. During the process of pulling back the traction plate 114, the welded horizontal pipe 3 is firmly fixed by the four inclined edge plates 115. The traction ball 117 slidingly arranged in the traction plate 114 can cooperate with the second traction spring 118 to avoid displacement of the horizontal pipe 3 during the pulling process, ensuring the stability of the horizontal pipe 3 and the vertical pipe 2 during movement. With the continuous retreat of the traction electric push rod 113, the opposite sides of the two horizontal pipes 3 will be in contact with the two conveying belts 111 respectively. At this time, the conveying belt 111 is started to drive the welded horizontal pipe 3 and the vertical pipe 2 to move towards the auxiliary pipe 4 until the welded horizontal pipe 3 and the vertical pipe 2 move to the middle section of the two conveying belts 111. It should be noted that when the traction plate 114 cooperates with the inclined edge plate 115 to pull back the horizontal pipe 3, the second clamp plate 139 will rotate through the clamp shaft 138 until the horizontal pipe 3 is separated from the second clamp plate 139 and the first clamp plate 137. At this time, the extension spring 136 immediately pulls the second extension plate to reset the second extension plate, ensuring the efficiency and accuracy of the entire assembly process.

[0070] When the welded horizontal pipe 3 and the vertical pipe 2 are pulled by the traction plate 114 and the bevel plate 115, two feeding electric push rods 168 are started at the same time, and the feeding electric push rods 168 will push the push rod 167 at the output end forward, so that the push rod 167 slides in the feeding bin 163, at this time the push rod will push the short pipe 5 to slide in the feeding bin 163 and the discharge hole 166, until the short pipe 5 corresponding to the push rod is pushed into the first arc-shaped magnet plate 174, then the feeding electric push rod 168 controls the push rod 167 to retract, when the push rod 167 is completely retracted, the feeding spring 164 will push the feeding push plate 165 upward, so that the feeding push plate 165 pushes all the short pipes 5 in the feeding bin 163 upward, facilitating the subsequent pushing operation of the push rod 167, ensuring that the short pipes 5 enter the first arc-shaped magnet plate 174 in turn, then the worker can put the auxiliary pipe 4 into the recess of the two second arc-shaped magnet plates 175, and the bottom end of the auxiliary pipe 4 is attached to the top of the auxiliary table 161, when it is necessary to supplement the short pipes 5 in the feeding bin 163, the worker only needs to open the feeding cover 169, and then put the short pipes 5 into the feeding bin 163, when the first arc-shaped magnet plate 174 and the second arc-shaped magnet plate 175 respectively adsorb the short pipe 5 and the auxiliary pipe 4, the conveying electric push rod 171 is started, which will push the connecting plate 172 at the output end, so that the connecting plate 172 drives the two clamping plates 173 to move towards the welded horizontal pipe 3 and the vertical pipe 2, the first arc-shaped magnet plate 174 and the second arc-shaped magnet plate 175 respectively arranged at both ends of the clamping plate 173 will firmly adsorb the corresponding short pipe 5 and auxiliary pipe 4, and under the pushing of the connecting plate 172, the clamping plate 173 gradually precisely butt joints the short pipe 5 and the auxiliary pipe 4 between the horizontal pipe 3 and the vertical pipe 2, at this time, the short pipe 5, the auxiliary pipe 4 and the welded horizontal pipe 3 and the vertical pipe 2 will reach the middle section of the conveyor belt 111 at the same time, after ensuring that each part is closely attached, the welding robot 7 is started to accurately weld the joint of the horizontal pipe 3 and the vertical pipe 2 and the short pipe 5 and the auxiliary pipe 4, after welding is completed, the welding robot 7 automatically returns to the original position, the conveyor belt 111 continues to operate, and the conveying electric push rod 171 retreats, until the welded overall scaffold is about to leave the edge of the conveyor belt 111, the grabbing mechanical arm 6 is started, so that the grabbing mechanical arm 6 accurately clamps the welded overall scaffold, after the scaffold completely leaves the conveyor belt 111, the grabbing mechanical arm 6 stably places it in the finished product area, ensuring that it is stacked neatly to avoid collision.
