Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline turning devices, specifically relating to a steel pipeline turning device. Background Technology

[0002] After steel pipes are manufactured, they usually need to be transferred from the workstation to a designated storage area. During the transfer process, the angle of the steel pipes needs to be adjusted due to changes in the width of the passageway or the required angle for stacking.

[0003] In existing technologies, when steel pipes are inside a workshop, they are usually turned horizontally or vertically using a combination of workshop cranes and manual assistance. Outside the workshop, however, a crane and manual labor are required to turn them vertically or horizontally. Both of these methods rely on hoisting, which requires a significant amount of manpower, such as controlling the position of the workshop crane and operating the hoisting machine. Furthermore, to improve stability during hoisting, the steel pipes need to be additionally secured to prevent slippage. Therefore, in actual use, this method is labor-intensive, inefficient, and poses safety risks. Utility Model Content

[0004] The present invention aims to provide a steel pipe turning device to solve the problems of low efficiency and high cost of the hoisting turning method mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe turning device, comprising... The mounting frame has multiple sets of conveying components installed at intervals. Each conveying component includes a first motor, a connecting shaft, and tapered rollers. The connecting shaft is rotatably mounted on the mounting frame, and two tapered rollers are symmetrically arranged on the connecting shaft. The first motor is mounted on the mounting frame, and the movable end of the first motor is connected to the connecting shaft for transmission. The rotating mechanism includes a base, a rotating shaft, and a power component. The rotating shaft is rotatably mounted on one end of the mounting bracket, the base is mounted on the bottom surface of the rotating shaft, and the power component is mounted on the mounting bracket and is used to drive the mounting bracket to rotate around the rotating shaft.

[0006] The principle and effects of this technical solution: 1. By placing the pipe on the conveying assembly, the conveying assembly can move the entire pipe to the mounting frame, and the mounting frame can rotate horizontally through the rotating mechanism to complete the pipe turning operation. Furthermore, the reverse movement of the conveying assembly can automatically complete the pipe unloading operation. In conjunction with conveyor belts and other methods, a streamlined loading-turning-unloading operation can be completed. Compared with hoisting methods, it saves more manpower and is safer and faster to use.

[0007] 2. The first motor drives the conical roller to rotate, which allows the pipes overlapping the conical roller to move under the influence of friction (moving onto or detaching from the mounting frame). By installing the base on the bottom surface and connecting the rotating shaft to the base and the mounting frame, the pipes placed on the mounting frame can be turned by rotating around the rotating shaft. Power is provided by the power component, and under the premise of setting the rotation angle and the range of motion of the first motor, automatic turning and automatic unloading operations can be completed. In conjunction with the feeding mechanism, automatic feeding can also be completed. The entire process does not require hoisting, which enhances safety.

[0008] The present invention is further configured such that: the power component includes a roller and a second motor, the roller is disposed at the bottom of the mounting frame, and the second motor is mounted on the bottom surface of the mounting frame and is connected to the roller for transmission.

[0009] The principle and effect of this technical solution: The second motor drives the roller to rotate, which in turn drives the mounting bracket to move. The mounting bracket rotates around the rotation axis, and the second motor can drive the roller to drive the mounting bracket to rotate around the rotation axis, which in turn drives the pipeline to change direction.

[0010] The present invention is further configured such that: multiple limiting frames are installed at intervals on the top of the mounting frame, and the cross-section of the limiting frames is "n" shaped.

[0011] The principle and effect of this technical solution: When the mounting bracket rotates around the rotation axis, centrifugal force is generated. During this process, the pipe placed on the conveying component may move relative to the conveying component. The setting of the limit bracket restricts the range of movement of the pipe to prevent the pipe from falling off the mounting bracket when turning, thus ensuring the stability of the pipe relative to the mounting bracket when turning.

[0012] The present invention is further configured such that a limiting plate is installed on the side of the mounting bracket near the rotating shaft.

[0013] The principle and effect of this technical solution: By setting the limit plate, the pipe being conveyed on the conveying component can be limited to avoid the pipe being directly detached from the mounting bracket due to excessive conveying by the conveying component.

[0014] The present invention is further configured as follows: it also includes a movable frame, and connecting screws are fixed on the two opposite outer walls of the mounting frame. Sliding grooves are opened on the two side walls of the movable frame, and the connecting screws are movably inserted into the sliding grooves. A hand-tightening nut is threaded on the connecting screw, and the hand-tightening nut abuts against the outer wall of the movable frame. The inner wall of the movable frame abuts against the outer wall of the mounting frame, and the limiting plate is fixed to the movable frame.

[0015] The principle and effect of this technical solution: By setting the connecting screw through the sliding groove, the connecting screw can restrict the position of the movable frame. That is, the movable frame can only move relative to the connecting screw through the sliding groove. Furthermore, by tightening the nut against the outer wall of the movable frame, the position of the movable frame relative to the mounting frame can be restricted. In other words, this solution can adjust the position of the limiting plate by controlling the position of the movable frame relative to the mounting frame, so that the position of the limiting plate can be adjusted according to the length of the pipeline.

[0016] The present invention is further configured such that at least two connecting screws are provided in a sliding groove.

[0017] The principle and effect of this technical solution: By setting two connecting screws, multi-point support can be formed, so that the movable frame will not rotate around the connecting screws, thus ensuring the stable sliding of the movable frame relative to the mounting frame.

[0018] The present invention is further configured to include a positioning block, which is installed on the ground.

[0019] The principle and effect of this technical solution: By setting the positioning block, the maximum rotation angle of the mounting bracket around the rotation axis can be limited, so as to avoid the situation where the mounting bracket fails to rotate to the designated position due to the excessive driving of the power component, thereby improving the reliability of the mounting bracket driving the steel pipe to turn.

[0022] Example 1, as shown in the appendix Figure 1-3 As shown, a steel pipe turning device includes a mounting frame 110 and a rotating mechanism. The mounting frame 110 is equipped with multiple sets of transmission components at intervals. Each set of transmission components includes a first motor 210, a connecting shaft 220, and a conical roller 230. The connecting shaft 220 is rotatably mounted on the mounting frame 110, and two conical rollers 230 are symmetrically arranged on the connecting shaft 220. The first motor 210 is mounted on the mounting frame 110, and the movable end of the first motor 210 is connected to the connecting shaft 220 for transmission (specifically, it can be transmitted by a coupling, gear transmission group, etc., which are conventional transmission technologies and are only briefly described here).

[0023] The rotating mechanism includes a base 310, a rotating shaft 320, and a power component. The rotating shaft 320 is rotatably mounted on one end of the mounting frame 110. The base 310 is mounted on the bottom surface of the rotating shaft 320 and fixed to the ground. The power component is mounted on the mounting frame 110 and is used to drive the mounting frame 110 to rotate around the rotating shaft 320. The power component includes rollers 330 and a second motor 340. The rollers 330 are mounted on the bottom of the mounting frame 110, and the second motor 340 is mounted on the bottom surface of the mounting frame 110 and is connected to the rollers 330 in a transmission connection (specifically, it can be driven by a coupling, gear transmission group, etc., to drive the rollers 330 to rotate by rotating the shaft of the rollers 330). In specific implementation, the number of rollers 330 can be greater than the number of second motors 340, that is, the second motor 340 only drives some of the rollers 330 to move.

[0024] In this design, the maximum length of the two conical rollers 230 along the connecting shaft 220 is 1044 mm. The first motor is a geared motor, and the spacing between adjacent conveying components is 2.8 m. Under this structure, the diameter of the largest conveying steel pipe is 3000 mm, the diameter of the lowest conveying steel pipe is 500 mm, the rotating shaft 320 is φ200 mm, the roller 330 is a φ300 mm steel wheel with a thickness of 100 mm, and the second motor is a geared motor.

[0025] The production line control system uses a PLC with Ethernet for communication, employing one master station and two slave stations. The master station is located in the main control cabinet of the production line, while the two slave stations are located in the control boxes of the rotating mechanisms. Data is transmitted in real time via a wireless module. To enable the steel pipe turning mechanism to have an automatic rotation function, multiple sensors are installed before and after the conical roller 230. Three DC three-wire inductive sensors and two photoelectric sensors can detect a distance of 300 cm to monitor the real-time position of the steel pipe. The rotating mechanism uses three DC three-wire inductive sensors to detect the rotation status and rotation angle.

[0026] Example 2, as shown in the appendix Figure 4 As shown, the difference from Embodiment 1 is that multiple limiting frames 120 are installed at intervals on the top of the mounting frame 110. The cross-section of the limiting frame 120 is "n" shaped, and the distance between the limiting frames 120 is 2.8m. The setting of the limiting frames 120 can prevent the steel pipe from detaching from the mounting frame 110.

[0027] Example 3, as shown in the appendix Figure 5 , 6 As shown, the difference from Embodiment 1 is that a movable frame 420 is also provided on the side of the mounting frame 110 near the rotating shaft 320. Two connecting screws 430 are fixed to the two opposite outer walls of the mounting frame 110, and the two connecting screws 430 are spaced apart. The cross-section of the movable frame 420 is U-shaped. Sliding grooves 421 are opened on the two side walls of the movable frame 420. The connecting screws 430 are movably inserted into the sliding grooves 421, and a hand-tightening nut 440 is threaded on the connecting screws 430. The hand-tightening nut 440 abuts against the outer wall of the movable frame 420, and the inner wall of the movable frame 420 abuts against the outer wall of the mounting frame 110. The limiting plate 410 is fixed to the movable frame 420.

[0028] Example 4, as shown in the appendix Figure 7 As shown, it also includes a positioning block 510 fixedly installed on the ground. The positioning block 510 is connected to the ground by bolts, specifically used to limit the rotation angle of the mounting frame 110. It can also mark the rotation angle range of the mounting frame 110 to prevent workers from being injured by the mounting frame 110 if they move into its rotation range. Any parts of this device not shown are the same as or can be implemented using existing technology.

[0029] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.
