Description

Technical Field

[0001] The utility model relates to the field of processing and transportation of workpieces, in particular to the repair and transportation of round towers and steel pipes. Background Art

[0002] At present, in the production and maintenance process of large circular towers and steel pipes, it is necessary to carry out operations such as handling and trimming of the workpieces.

[0003] Chinese patent application No. 202410371584.7 discloses a continuous welding device for steel structures, which can perform welding operations on steel pipes. Steel pipes of different specifications can be placed using a support mechanism. However, since the distance between the rollers in contact with the steel pipe is adjusted by rotating a movable bracket, the adjustment range is small, resulting in a small range of steel pipe diameters suitable for the welding device. The welding device is not provided with a moving mechanism, which is inconvenient for the next process operation.

[0004] At present, no technical solution that can solve the above technical problems has been found in the existing public technologies. Utility Model Content

[0024] like Figure 1-3As shown, an opening and closing walking turntable device includes a base 1, a rotating roller 3 and a walking wheel 4. The front and rear parts of the base 1 are detachably connected by bolts, and the length of the base 1 can be increased or decreased according to the workpiece 16. An opening and closing device is respectively arranged on the front and rear sides of the base 1, and the opening and closing device includes a U-shaped fixing frame 201 arranged on the left and right sides of the base 1 and a power mechanism for driving the U-shaped fixing frame 201 to move left and right, and the protruding ends 202 on both sides of the U-shaped fixing frame 201 are arranged obliquely inward. The rotating roller 3 is rotatably arranged on the protruding end 202 of the U-shaped fixing frame 201 through a bearing, and a rotating drive motor 5 is arranged on one side of the rotating roller 3. The workpiece 16 is placed on the rotating roller 3, and the rotating drive motor 5 drives the rotating roller 3 to rotate through a gear, thereby driving the workpiece 16 to rotate, which is convenient for the finishing operation of the workpiece 16, such as grinding, finishing, anti-corrosion and welding. Preferably, a rubber layer is arranged on the rotating roller 3. The power mechanism drives the U-shaped fixing frame 201 to move left and right. Compared with the rotation of the U-shaped fixing frame 201 with its bottom as the center, the horizontal movement range of the rotary roller 3 is greatly expanded, thereby expanding the application range of the device to workpieces 16 with different diameters. The running wheel 4 is arranged at the bottom of the base 1. The running wheels 4 on the left and right sides are connected by a transmission shaft 15. The base 1 is provided with a driving motor 14, which is connected to the transmission shaft 15 through a chain belt, thereby driving the running wheel 4 to rotate. The setting of the running wheel 4 integrates the transportation and repairing devices, reduces frequent manual operations, and improves production quality and production efficiency. When the workpiece 16 is produced and repaired, the flow path between the processes is fixed, so a track 13 is laid on the flow path, and the running wheel 4 cooperates with the track 13, and the running wheel 4 can run on the track 13.

[0025] The power mechanism includes a screw rod 6 which is rotatably arranged on the base 1 through a bearing and a nut 8 which is fixedly arranged at the bottom end of the U-shaped fixing frame 201; a slideway 9 which matches the U-shaped fixing frame 201 is arranged on the base 1, and the slideway 9 is arranged in the left and right directions. The screw rod 6 matches the nut 8, and the screw rod 6 is rotated, and the U-shaped fixing frame 201 moves left and right under the restriction of the slideway 9, as shown in FIG. Figure 1 As shown, one end of the screw rod 6 extends out of the base 1 and is provided with a handle 10. The screw rod 6 is a bidirectional screw rod, which is a bidirectional screw rod having two sections of threads with different rotation directions at both ends of the main body, and a nut is screwed on each of the two ends. When the main body is rotated, the two nuts will quickly approach or separate due to the different rotation directions; the setting of the bidirectional screw rod speeds up the adjustment of the distance between the left and right U-shaped fixing frames 201, thereby improving work efficiency.

[0026] Since the force exerted by the workpiece 16 on the opening and closing device is not vertically downward, a part of the horizontal force will act on the opening and closing device. When the weight of the workpiece 16 is too large, the opening and closing device will move outward, destroying the stability of the device. A locking mechanism is set between the opening and closing device and the base 1. The locking mechanism includes a first fixing hole 11 and a second fixing hole 12 that cooperate with each other. A plurality of first fixing holes 11 are arranged on the base 1 in a horizontal direction, such as Figure 3 As shown, there are 20 first fixing holes 11 arranged in the horizontal direction. In order to fix more firmly, a group of first fixing holes 11 can be set on the base 1 on the front and rear sides of the opening and closing device respectively; the bottom end of the U-shaped fixing frame 201 extends out of the probe plate, and the second fixing holes 12 are set on the probe plate. The first fixing holes 11 and the second fixing holes 12 are fixed by bolts or pins.

[0027] In order to place the workpiece 16 more firmly, Figure 1 As shown, the center of the workpiece 16 and the midpoint of the line connecting the centers of the two rotating rollers 3 on the U-shaped fixing frame 201 are connected into a straight line, and the angle between the two straight lines in the same opening and closing device is 45°~100°. Preferably, the angle between the two straight lines in the same opening and closing device is 60°.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
