The diamond-shaped slider 115 and the displacement screw 116 constitute a spiral pair, and a displacement motor 117 is fixedly installed on the cross slide 112. The output shaft of the displacement motor 117 and the displacement screw 116 are fixedly connected, and trapezoidal push blocks 118 are fixedly arranged on the side surfaces of the L-shaped slide 113. The inclined surfaces on the four trapezoidal push blocks 118 are respectively in contact with the corresponding inclined surfaces on the diamond-shaped slider 115.

[0029] In the initial position, the center line of the diamond slider 115 and the axis of the switching motor 111 are in the same straight line. At this time, under the action of the diamond slider 115 and the trapezoidal push block 118, the springs between the L-shaped slide 113 and the cross slide 112 are not compressed. At this time, the two arc-shaped clamping blocks 114 in the same clamping unit are located at the closest position.

[0030] The shift motor 107 is started to drive the shift screw 106 to rotate, so that the T-shaped slide 105 moves horizontally relative to the base 101.

[0031] A positioning slide 102 is slidably mounted on the base 101, a positioning screw rod 103 is rotatably mounted on the base 101, the positioning screw rod 103 and the positioning slide 102 constitute a spiral pair, a positioning motor 104 is fixedly mounted on the base 101, the output shaft of the positioning motor 104 is fixedly connected to the positioning screw rod 103, a plurality of placement components are arranged on the positioning slide 102, the placement components each include two symmetrically arranged clamping units 2, the clamping units 2 each include a strip rotating plate 122 and two symmetrically slidably mounted T-shaped slides 119 on the positioning slide 102, a spring is arranged between the T-shaped slide 119 and the positioning slide 102, an arc-shaped clamping block 114 is fixedly mounted on the lower end of the T-shaped slide 119, the strip rotating plate 122 is rotatably mounted on the positioning slide 102, and the strip rotating plate 122 is used to push the corresponding two T-shaped slides 119 to slide.

[0032] The placement assembly also includes a driving gear plate 128 and a limiting ratchet ring 131. The driving gear plate 128 is rotatably mounted on the adjustment slide 102. There is friction between the driving gear plate 128 and the adjustment slide 102. Under the action of the friction between the adjustment slide 102 and the driving gear plate 128, the driving gear plate 128 will not rotate relative to the adjustment slide 102 when no external force is applied. A transmission gear 133 is rotatably mounted on the bar rotating plate 122. A torsion spring is arranged between the bar rotating plate 122 and the transmission gear 133. One end of the torsion spring is fixedly connected to the bar rotating plate 122, and the other end of the torsion spring is fixedly connected to the transmission gear 133. The driving gear plate 128 is meshed with the corresponding two transmission gears 133 to form a gear pair. The limiting ratchet ring 131 is fixedly installed on the adjustment slide 102. The limiting ratchet 130 is fixedly installed on the driving gear plate 128. The limiting ratchet 130 and the limiting ratchet ring 131 are engaged to form a ratchet mechanism. The axes of the transmission block 127, the driving gear plate 128, the limiting ratchet 130 and the limiting ratchet ring 131 in the same placement assembly are on the same straight line.

[0033] In the initial position, the spring between the T-shaped slide 119 and the adjustment slide 102 is compressed, and the two T-shaped slides 119 in the same clamping unit 2 are located at the closest position. At this time, both ends of the strip rotating plate 122 do not contact the side of the T-shaped slide 119.

[0034] Under the action of the limiting ratchet 130 and the limiting ratchet ring 131, the limiting ratchet 130 is driven to rotate relative to the limiting ratchet ring 131, and the driving gear plate 128 is rotated synchronously. At this time, the limiting ratchet 130 is driven to rotate in the opposite direction. Under the action of the limiting ratchet ring 131, the limiting ratchet 130 will not rotate. The driving gear plate 128 rotates to make the corresponding two transmission gears 133 rotate. Under the action of the torsion spring between the bar rotating plate 122 and the transmission gear 133, the bar rotating plate 122 rotates synchronously, thereby making The two ends of the strip rotating plate 122 respectively contact the surfaces of the T-shaped slides 119 on both sides, and the strip rotating plate 122 continues to rotate, so that the two T-shaped slides 119 corresponding to the strip rotating plate 122 move in the direction away from the transmission gear 133 corresponding to the strip rotating plate 122, that is, the two T-shaped slides 119 move away from each other, and then the arc clamping blocks 114 corresponding to the two T-shaped slides 119 move away from each other, and the spring between the T-shaped slide 119 and the adjustment slide 102 is compressed.

[0035] A driving assembly is provided on the positioning slide 102, and the driving assembly includes a transposition slide 124, which is slidably mounted on the upper surface of the positioning slide 102, a transposition screw rod 120 is rotatably mounted on the positioning slide 102, and the transposition slide 124 and the transposition screw rod 120 constitute a spiral pair, a transposition motor 123 is fixedly mounted on the positioning slide 102, and the output shaft of the transposition motor 123 is fixedly connected to the transposition screw rod 120, a straight-line rotating plate 126 is rotatably mounted on the transposition slide 124, a driving motor 125 is fixedly mounted on the positioning slide 124, and the output shaft of the driving motor 125 is fixedly connected to the straight-line rotating plate 126, and a transmission round block 127 is fixedly mounted on the limiting ratchet 130, and the transmission round block 127 is provided with a straight-line sliding groove 135 that cooperates with the straight-line rotating plate 126.

[0036] In the initial position, the position of the straight-line chute 135 on the transmission round block 127 is parallel to the axis of the transposition screw 120 , and at this time, the corresponding inner side surfaces of the plurality of straight-line chute 135 are on the same plane.

[0037] Then, the driving motor 125 is started to drive the straight-line rotating plate 126 to rotate, so that the side surfaces on both sides of the straight-line rotating plate 126 are parallel to the inner side surfaces of the straight-line sliding groove 135 at this time, and then the transposition motor 123 is started to drive the transposition screw rod 120 to rotate, that is, the transposition slide plate 124 slides relative to the adjustment slide plate 102, so that the transposition slide plate 124 moves to the top of the component to be adjusted. At this time, the straight-line rotating plate 126 is engaged with the straight-line sliding groove 135 on the transmission round block 127 in the placement component, and at this time, the axis of the transmission round block 127 in the placement component and the axis of the driving motor 125 are in the same straight line, and then the driving motor 125 is started to drive the straight-line rotating plate 126 to rotate, that is, the transmission round block 127 in the placement component is engaged with the straight-line sliding groove 135. The round block 127 rotates, thereby causing the driving gear plate 128 and the limiting ratchet 130 to rotate synchronously. Under the action of the transmission gear 133, the two bar-shaped rotating plates 122 in the placement assembly rotate synchronously, that is, the two T-shaped slides 119 in the clamping unit 2 in the placement assembly move away from each other. When the bar-shaped rotating plate 122 causes the two relative T-shaped slides 119 to move to the farthest position, the bar-shaped rotating plate 122 continues to rotate, and the bar-shaped rotating plate 122 gradually loosens its support for the T-shaped slides 119, and the two T-shaped slides 119 move toward each other, eventually causing the bar-shaped rotating plate 122 to move to the initial position. At this time, the straight-line rotating plate 126 and the transmission round block 127 rotate 360 ​​degrees synchronously.

[0038] The driving assembly also includes two long slides 121 symmetrically and slidably mounted on the upper surface of the positioning slide 102, a spring is arranged between the long slide 121 and the positioning slide 102, and the long slide 121 is fixedly provided with driving racks 134 equal to the number of the placement components, and the bar-shaped rotating plate 122 is fixedly mounted with a driven gear 129, and the driven gear 129 and the corresponding driving rack 134 form a gear pair and a rack pair when meshing, and the positioning slide 102 is rotatably mounted with a driving cam 132, and another transmission round block 127 is fixedly mounted on the upper surface of the driving cam 132, and the transmission round block 127 on the driving cam 132 is also provided with a straight groove 135 that cooperates with the straight rotating plate 126, and when the spring between the positioning slide 102 and the long slide 121 is not deformed, the driven gear 129 does not contact the corresponding driving rack 134.

[0039] In the initial position, the spring between the long slide 121 and the adjustment slide 102 is not deformed. At this time, the two long slides 121 are located at the closest position, that is, at this time, the driving rack 134 is not in contact with the corresponding driven gear 129, and at this time, the end of the driving cam 132 does not contact the surface of the long slide 121, and the straight groove 135 on the transmission circle 127 on the driving cam 132 and the straight groove 135 on the transmission circle 127 in the placement assembly are in the same position relative to the axis of the shifting screw 120.

[0040] The shifting motor 123 is started to drive the shifting slide 124 to move, so that the shifting slide 124 moves to the top of the driving cam 132. At this time, the axis of the driving motor 125 and the axis of the transmission round block 127 on the driving cam 132 are in the same straight line, and at this time, the straight-line rotating plate 126 is engaged with the straight-line sliding groove 135 on the transmission round block 127. Then the driving motor 125 is started to drive the straight-line rotating plate 126 to rotate, so that the driving cam 132 rotates. When the end face of the driving cam 132 rotates to contact the side of one of the two long slides 121, the long slide 121 moves in the direction away from the other long slide 121. At this time, the other long slide 121 does not move, and the spring between the long slide 121 and the adjustment slide 102 is compressed, and the driving rack 134 on the long slide 121 is synchronously The driven gear 129 is rotated and the bar rotating plate 122 is rotated synchronously. Under the action of the limiting ratchet 130 and the limiting ratchet ring 131, the driving gear plate 128 will not rotate under the action of the transmission gear 133, that is, the transmission gear 133 will not rotate, and the torsion spring between the bar rotating plate 122 and the transmission gear 133 is compressed. Under the action of the driving rack 134 on the long slide 121, the multiple bar rotating plates 122 located on the same side of the adjusting slide 102 are all rotated, that is, the two T-shaped slides 119 in the multiple clamping units 2 located on the same side of the adjusting slide 102 are moved away from each other, and the driving cam 132 continues to rotate. When the end of the driving cam 132 is out of contact with the long slide 121, the bar rotating plate 122 returns to its initial position under the action of the torsion spring between the bar rotating plate 122 and the transmission gear 133.

[0041] Working principle: A steel pipe placing rack is provided on the base 101, and the rack is not located under the positioning slide 102. Then the shift motor 107 is started to move the T-shaped slide 105 to the top of the steel pipe to be taken on the steel pipe placing rack. Then the switching motor 111 is started to move one of the two clamping units to the position closest to the steel pipe. Then the displacement motor 117 is started to move the diamond slider 115 toward the arc clamping block 114 in the clamping unit, so that the two arc clamping blocks 114 in the clamping unit move away from each other. The steel pipe is moved in the direction of rotation, and then the shift motor 110 is started to move the L-shaped slide 108 downward, so that the clamping unit 1 moves downward, and then the two arc-shaped clamping blocks 114 in the clamping unit 1 move to the two sides of the steel pipe, and then the displacement motor 117 is started to make the diamond slider 115 return to the initial position, and under the action of the spring between the L-shaped slide 113 and the cross slide 112, the two arc-shaped clamping blocks 114 in the clamping unit 1 can clamp and fix the steel pipe, and then the shift motor 110 is started to move the L-shaped slide 108 upward, so as to clamp the steel pipe.

[0042] Then, the switching motor 111 is started to drive the cross slide 112 to rotate 180 degrees, so that the clamping unit 1 that clamps the steel pipe is located at the farthest position from the lower surface of the base 101, and then the shifting motor 107 is started to move the T-shaped slide 105 to be directly below the placement component to be installed. At this time, the steel pipe is located directly below the placement component to be installed, and then the transposition motor 123 is started to drive the transposition slide 124 to move, so that the transposition slide 124 moves to be directly above the placement component to be installed. At this time, the straight-line rotating plate 126 engages with the straight-line sliding groove 135 on the transmission round block 127 in the placement component, and then the driving motor 125 is started to drive the straight-line rotating plate 126 to rotate, that is, the driving gear plate 128 rotates, and then the two strip rotating plates 122 in the placement component are rotated, that is, the two T-shaped slides 119 in the clamping unit 2 in the placement component move away from each other, and the arc-shaped clamping block 114 on the T-shaped slide 119 moves synchronously.

[0043] Finally, the two T-shaped slides 119 are moved to the farthest position, and then the shift motor 110 is started to move the steel pipe upward, so that the steel pipe moves to the position between the arc-shaped clamping blocks 114 at the lower ends of the two opposite T-shaped slides 119, and the drive motor 125 is continued to be started to drive the two bar-shaped rotating plates 122 to rotate, so that the two bar-shaped rotating plates 122 return to the initial position. At this time, the straight-line rotating plate 126 and the transmission circle 127 rotate 360 ​​degrees synchronously. Under the action of the spring between the T-shaped slide 119 and the adjustment slide 102, the arc-shaped clamping block 114 at the lower end of the T-shaped slide 119 clamps and fixes the steel pipe. Repeating the above steps can achieve clamping and fixing of the steel pipe by multiple placement components.

[0044] Then, the adjusting motor 104 is started to drive the adjusting screw rod 103 to rotate, so that the adjusting slide plate 102 moves downward, and then the multiple steel pipes clamped on the adjusting slide plate 102 move downward, so as to facilitate the subsequent galvanizing of the steel pipes. During the galvanizing process of the steel pipes, the transposition motor 123 is started to move the transposition slide plate 124 to the top of the driving cam 132, and the straight-shaped rotating plate 126 is engaged with the transmission round block 127 on the driving cam 132. Then, the driving motor 125 is started to drive the driving cam 132 to rotate, so that the ends of the driving cam 132 are successively It contacts the side surfaces of the two long slides 121, that is, firstly the arc-shaped clamping blocks 114 in the multiple clamping units 2 located on the same side of the adjusting slide 102 loosen the fixation on the steel pipe, so as to facilitate galvanizing of the clamping position of the steel pipe. After the galvanizing of the clamping position is completed, the driving cam 132 continues to rotate, so that the arc-shaped clamping blocks 114 in the multiple clamping units 2 on this side continue to clamp the steel pipe, and then the arc-shaped clamping blocks 114 in the multiple clamping units 2 on the other side loosen the clamping of the steel pipe, so as to facilitate galvanizing of the clamping position of the steel pipe.

[0045] After completing the galvanizing process on the steel pipe, perform the above steps in reverse. Under the action of the auxiliary components, clamp the steel pipes on the placement components one by one and place them on the steel pipe placement rack. Repeat the above steps to achieve continuous batch loading of galvanized steel pipes.

[0046] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
