Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe transportation, in particular to a steel pipe transportation device. Background Art

[0002] Steel pipes have a hollow cross-section, with their length much greater than their diameter or circumference. They are categorized by cross-sectional shape into round, square, rectangular, and special-shaped steels; by material, into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steels; and by application, into pipes for pipelines, engineering structures, thermal equipment, the petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment. By production process, they are categorized into seamless steel pipes and welded steel pipes, with seamless pipes further divided into hot-rolled and cold-rolled types, and welded steel pipes further divided into straight-seam welded pipes and spiral-seam welded pipes.

[0003] During the production and transportation of steel pipes, it is necessary to transport the steel pipes piled on the ground to other processing locations. Existing steel pipe handling equipment cannot transport multiple steel pipes at a time, and the operation is relatively complicated, which affects the efficiency of steel pipe production. Based on the shortcomings of the existing technology, the utility model designs a steel pipe handling device. Utility Model Content

[0006] As an optimal technical solution of the present invention, a transmission rod is installed at one end of the output shaft of the two servo motors, and a first spur gear is installed at one end of the transmission rod. The first spur gear is engaged with one of the tooth grooves, and a first bevel gear is fixedly installed on the outer surface of the two transmission rods.

[0010] As a preferred technical solution of the present invention, a second spur gear is fixedly mounted on the other end of the two sleeve rods, and the two second spur gears are meshed with another set of tooth grooves.

[0011] As a preferred technical solution of the present invention, movable structures are installed on both sides of the outer surfaces of the two installation frames, and the four movable structures include support plates.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This steel pipe handling device, through the drive structure and the clamp structure, is used to move a pile of steel pipes on the ground. The device is passed through the middle of the steel pipe pile, and then the servo motors on both sides are simultaneously started, causing the first and second spur gears on both sides to rotate in opposite directions. As a result, two clamp steel rings are extended from both sides of the installation frame and form a circular ring from the bottom of the steel pipe pile, thereby clamping the steel pipe pile at both ends. This achieves the purpose of the device being able to carry multiple steel pipes at a time and being easy to operate.

[0015] 2. This steel pipe handling device uses a push handle and a moving structure.

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 A steel pipe handling device includes a main steel frame 1, a push handle 2 is fixedly installed at the middle position of the top of the main steel frame 1, driving structures 3 are installed on both sides of the top of the main steel frame 1, and clamping structures 4 are installed at both ends of the main steel frame 1; the two driving structures 3 include a base 31, a fixing frame 32 and a sleeve rod 38, and servo motors 33 are installed inside the two bases 31; the two clamping structures 4 include mounting frames 41, and the inner walls of both sides of the two mounting frames 41 are provided with symmetrical arc-shaped clips 42, and the outer surfaces of the two arc-shaped clips 42 are slidably installed with clamping steel rings 43, and the interiors of the two clamping steel rings 43 are provided with tooth grooves 44.

[0024] See also Figure 2-3 A transmission rod 35 is mounted on one end of the output shaft of the two servo motors 33, and a first spur gear 36 is mounted on one end of the transmission rod 35. The first spur gear 36 meshes with one of the tooth grooves 44, and a first bevel gear 34 is fixedly mounted on the outer surface of the two transmission rods 35. The two fixing frames 32 are fixedly connected to the main steel frame 1, and a second bevel gear 37 is rotatably mounted on the bottom of the two fixing frames 32. The two second bevel gears 37 mesh with the first bevel gear 34. Two sleeve rods 38 are rotatably connected to the mounting frame 41, and the two sleeve rods 38 are sleeved on the outer surface of the transmission rod 35. A third bevel gear 39 is mounted on one end of the two sleeve rods 38. The third bevel gear 39 meshes with the outer surface of the second bevel gear 37. A second spur gear 310 is fixedly mounted on the other end of the two sleeve rods 38. The two second spur gears 310 mesh with another set of tooth grooves 44.

[0025] By driving the servo motor 33, its output shaft can drive the transmission rod 35 to rotate, thereby allowing the transmission rod 35 to drive the first spur gear 36 to rotate, thereby allowing the corresponding hoop steel ring 43 to rotate. At the same time, since the first bevel gear 34, the second bevel gear 37, and the third bevel gear 39 are engaged with each other, the third bevel gear 39 can rotate in the opposite direction to the first spur gear 36 through the second bevel gear 37, thereby allowing the second spur gear 310 to drive the other hoop steel ring 43 to rotate in the opposite direction, thereby allowing the two hoop steel rings 43 to form a circular ring to clamp the steel pipe stack.

[0026] See also Figure 2 and Figure 5 The outer surfaces of the two mounting frames 41 are provided with movable structures 5 on both sides, and the four movable structures 5 include support plates 51. Hydraulic cylinders 52 are installed on the tops of the four support plates 51, and movable wheels 53 are installed at one end of the telescopic rods of the four hydraulic cylinders 52.

[0027] Through the push handle 2 and the movable structure 5, after the steel pipes are stacked with the clamp structures 4 on both sides, the four hydraulic cylinders 52 are driven to make the telescopic rods drive the main steel frame 1 and the clamp structures 4 on both sides to rise upward. Then the staff can move the device by pushing the push handle 2, which is very convenient.

[0028] Working principle: when a steel pipe handling device is used, the device is first passed through the middle of the steel pipe pile, and then the servo motors 33 on both sides are started at the same time. Through the drive of the servo motor 33, its output shaft can drive the transmission rod 35 to rotate, thereby allowing the transmission rod 35 to drive the first spur gear 36 to rotate, thereby allowing the corresponding clamping steel ring 43 to rotate. At the same time, since the first bevel gear 34, the second bevel gear 37, and the third bevel gear 39 are engaged with each other, the third bevel gear 39 can be rotated in the opposite direction to the first spur gear 36 through the second bevel gear 37, thereby allowing the second spur gear 310 to drive the other clamping steel ring 43 to rotate in the opposite direction, thereby allowing the two clamping steel rings 43 to extend from both sides of the mounting frame 41 and form a circular ring from the bottom of the steel pipe pile, thereby clamping the two ends of the steel pipe pile, and then through the drive of the four hydraulic cylinders 52, the telescopic rod drives the main steel frame 1 and the clamping structures 4 on both sides to rise upward, and then the staff can move the device by pushing the push handle 2.
