Description

Technical Field

[0001] This utility model belongs to the field of automatic pickling and transportation technology for steel pipes, and particularly relates to an automatic pickling and transportation vehicle for steel pipes. Background Technology

[0002] Pickling is a surface treatment process for steel pipes. Its main purpose is to remove impurities such as rust and oxide scale from the surface of the steel pipes to improve their surface quality and corrosion resistance. Pickling mainly utilizes the chemical reaction between acid solution and oxides on the surface of the steel pipe, causing them to dissolve and fall off. Common pickling solutions include hydrochloric acid, sulfuric acid, and nitric acid, and different pickling solutions have different characteristics and applicable ranges.

[0003] After pickling, steel pipes need to be gripped by a grabbing device and then removed from the pickling tank by a lifting device. However, common lifting devices often sway during the lifting process, which can cause the steel pipes to fall off. Falling pipes can easily lead to damage and wasted resources. Therefore, we propose an automated steel pipe pickling and transport vehicle. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic pickling and transport vehicle for steel pipes to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an automatic pickling and transport vehicle for steel pipes, comprising:

[0006] A fixed frame has a sliding groove inside, in which two movable frames are slidably installed. A common connecting frame is fixedly installed between the two movable frames. Two support rods are fixedly installed on both sides of each movable frame. A rectangular groove is opened inside the movable frame, in which a lifting rod is slidably installed. Four rotating frames are symmetrically fixedly installed on the inner wall of the rectangular groove and around the periphery of the lifting rod. A rotating roller is rotatably installed inside each rotating frame. A rubber pad is fixedly installed around the periphery of each rotating roller, and the periphery of the rubber pad is in contact with the periphery of the lifting rod.

[0007] Two U-shaped frames are fixedly installed on the top of two movable frames. Two rollers are rotatably installed inside each U-shaped frame. A mounting frame is fixedly installed on one side of each U-shaped frame. A take-up roller is rotatably installed inside the mounting frame. Two steel wire ropes are fixedly installed on the take-up roller. One end of each steel wire rope passes through the top of the two rollers and is fixed to the lifting rod. A motor is fixedly installed on one side of the mounting frame. The output end of the motor passes through one side of the mounting frame and is coaxially connected to the take-up roller.

[0008] A drive assembly, located within a fixed frame, is used to drive two movable frames to move.

[0009] In this technical solution, during use, personnel can simultaneously start two motors. The output shafts of the two motors will drive two take-up rollers to rotate. The rotation of the take-up rollers will wind two steel wire ropes around them. At this time, the steel wire ropes will slide on the corresponding rollers. Under the action of friction, the sliding of the steel wire ropes will drive the rollers to rotate, causing the rollers to rotate within the U-shaped frame. Simultaneously, the two steel wire ropes will also pull the lifting rod up and down. Under the action of friction, the upward movement of the lifting rod will drive eight rotating rollers to rotate, causing the rotating rollers to rotate on the rotating frame. At the same time, rubber pads can protect the lifting rod, ensuring that the lifting rod will not wear out during the lifting process. In addition, the eight rubber pads will press against the periphery of the lifting rod, ensuring that the lifting rod will not wobble during the lifting process, thereby ensuring the stability of the lifting rod. The lifting of the two lifting rods can drive the gripping device to lift and lower.

[0010] Subsequently, the two moving frames are moved by the drive components, and the movement of the two moving frames will move the connecting frame, which in turn will move the gripping device, which will then move the pickling steel pipe.

[0011] In the above technical solution, the driving component further includes:

[0012] A threaded rod is rotatably mounted in a sliding groove. One end of the threaded rod passes through two movable frames. A rotating groove is provided in the fixed frame on one side of the sliding groove. A bevel gear one is rotatably mounted in the rotating groove. One end of the bevel gear one extends through one side of the rotating groove into the sliding groove and is coaxially connected to the threaded rod. A bevel gear two is meshed at the top of the bevel gear one and located in the rotating groove. A motor two is fixedly mounted at the top of the fixed frame and above the rotating groove. The output end of the motor two extends through the top of the fixed frame into the rotating groove and is coaxially connected to the bevel gear two.

[0013] In this technical solution, starting motor two causes the output shaft of motor two to drive bevel gear two to rotate. Under the action of meshing, the rotation of bevel gear two drives bevel gear one to rotate. The rotation of bevel gear one drives the threaded rod to rotate. Under the action of the thread, the rotation of the threaded rod drives two moving frames to move. At the same time, the movement of the two moving frames drives the connecting frame to move, thereby driving the gripping device to move. The gripping device drives the pickled steel pipe to move.

[0014] In the above technical solution, the threaded rod is further threadedly connected to the two movable frames, the second bevel gear is rotatably connected to the rotating groove, and the output shaft of the second motor is rotatably connected to the fixed frame and the rotating groove.

[0015] In this technical solution, it is ensured that the rotation of the threaded rod can drive the two moving frames to move, that the second bevel gear can rotate normally in the rotating groove, and that the output shaft of the second motor can rotate normally in the fixed frame and the rotating groove.

[0016] In the above technical solution, the output shaft of the motor is rotatably connected to the mounting bracket, and the wire rope is slidably connected to the roller.

[0017] In this technical solution, it is ensured that the output shaft of motor one can rotate normally within the mounting bracket, and that the wire rope can slide normally on the roller.

[0018] In the above technical solution, the support rod is further described as having an inclined structure.

[0019] In this technical solution, the structural stability of the support rod is ensured.

[0020] In the above technical solution, both of the movable frames are further welded tightly to the connecting frame.

[0021] In this technical solution, the structural stability of the two movable frames and the connecting frame is ensured.

[0022] In the above technical solution, the cross-section of the mobile frame is T-shaped.

[0023] In this technical solution, the structural stability of the mobile frame is ensured.

[0024] Furthermore, in the above technical solution, the movable frame and the U-shaped frame are integrally formed.

[0025] In this technical solution, the structural stability of the movable frame and the U-shaped frame is ensured.

[0026] The beneficial effects of this utility model are:

[0027] This automatic pickling and transport vehicle for steel pipes, through the coordinated operation of two motors, two winding rollers, two wire ropes, two rollers, two lifting rods, eight rotating rollers, and eight rubber pads, ensures that the lifting rods do not sway during the lifting process, thus guaranteeing the stability of the lifting rods. The lifting of the two lifting rods can drive the gripping device to lift and lower. Attached Figure Description

Example

[0040] This embodiment provides an automatic pickling and transport vehicle for steel pipes, including:

[0041] A fixed frame 1 has a sliding groove 2 inside the fixed frame 1. Two movable frames 3 are slidably installed in the sliding groove 2. The same connecting frame 15 is fixedly installed between the two movable frames 3. Two support rods 4 are fixedly installed on both sides of the movable frame 3. A rectangular groove 5 is opened inside the movable frame 3. A lifting rod 6 is slidably installed in the rectangular groove 5.

At the same time, the eight rubber pads 14 will press the periphery of the lifting rod 6 to ensure that the lifting rod 6 will not wobble during the lifting process, thus ensuring the stability of the lifting rod 6. The lifting of the two lifting rods 6 can drive the gripping device to lift and lower.
