DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a supporting base 1 and two U-shaped supporting bases 2, the two U-shaped supporting bases 2 are symmetrically distributed on the top of the supporting base 1, the tops of the two U-shaped supporting bases 2 are hinged with two arc plates 3, a torsion spring is arranged between the arc plate 3 and the corresponding U-shaped supporting base 2, one side of the arc plate 3 is rotatably connected with a plurality of rotating rods 31, the side walls of the plurality of rotating rods 31 are fixedly connected with two pipe supporting rollers 311 for driving a pair of pipes, two slots 21 are provided on the inner sides of the two U-shaped supporting bases 2, the bottom ends of the four arc plates 3 are fixedly connected with a connecting plate 4, the connecting plate 4 is plugged into the inner walls of the corresponding slots 21, a limiting groove 41 is provided on the top of the connecting plate 4, the inner walls of the two U-shaped supporting bases 2 are slidably connected with a limiting wedge rod 5, and the limiting wedge rod 5 is plugged into the inner walls of the corresponding limiting groove 41.

[0019] In this embodiment: the support base 1 supports the bottom of each component of the device, and the two U-shaped support bases 2 support the corresponding two arc plates 3. The arc plate 3 is flipped at one end of the corresponding U-shaped support base 2 to adjust the angle. The inner arc surface of the U-shaped support base 2 is limited after the arc plate 3 is flipped at an angle to prevent the arc plate 3 from flipping too much and losing the ability to support the pipeline. The arc plate 3 drives a number of rotating rods 31 to rotate and adjust the angle. The diameter of the pipeline support roller 311 is larger than the rotating rod 31, so that one side of the pipeline support roller 311 can extend out of the arc The curved plate 3 contacts the side wall of the pipeline through the pipeline support roller 311, and the pipeline falls from the corresponding two curved plates 3 from top to bottom. The pipeline presses down and flips the two curved plates 3, so that the curved plates 3 can flip toward the corresponding U-shaped supporting frame 2. Then, the four curved plates 3 clamp and fix the pipeline, and the curved plates 3 can be flipped stably by the weight of the pipeline itself. The pipeline is limited above the curved plate 3, and when the curved plate 3 flips toward the curved inner wall of the U-shaped supporting frame 2, the curved plate 3 drives the corresponding connecting plate 4 to the slot 21 The connecting plate 4 is rotated in the direction of rotation, and then the connecting plate 4 is inserted into the corresponding slot 21. When the arc plate 3 contacts the arc-shaped inner wall of the U-shaped support base 2, the limiting wedge rod 5 is inserted into the limiting groove 41, so as to limit the connecting plate 4 and prevent the connecting plate 4 from detaching from the slot 21, so that the connecting plate 4 can limit the arc plate 3, and then the clamping and fixing of the four arc plates 3 to the pipe becomes more stable, preventing the pipe from shaking and detaching during the cutting process, and cutting the pipe through the cutting component at the top of the support base 1, so that the pipe is placed from top to bottom. Automatic locking can be achieved on the device, and the operation is simple and convenient, which reduces the time and steps for fixing the pipeline, thereby improving the work efficiency of pipeline cutting. At the same time, the arc plate 3 uses a plurality of pipeline support rollers 311 to contact the pipeline, and controls the rotation of a plurality of pipeline support rollers 311 to rotate the pipeline, so that the pipeline can be rotated, and then the different angles of the pipeline can be rotated to the bottom to correspond to the cutting component, thereby facilitating the cutting work of the cutting component on the pipeline, and there is no need to unlock the limit of the pipeline and then rotate it, the operation is more convenient and quick, and the work efficiency is further improved.

[0020] The side walls of the four arc-shaped plates 3 are fixedly connected with a plurality of transmission teeth 312, and the plurality of transmission teeth 312 are located between the corresponding two pipe support rollers 311. The inner wall of the arc-shaped plate 3 is rotatably connected with two driving gears 32, and a transmission chain 33 for driving the plurality of transmission teeth 312 is arranged between the two driving gears 32. The pipe support rollers 311 and the pipe contact surface are fixedly connected with an anti-skid layer 313; the two driving gears 32 inside the arc-shaped plate 3 are synchronously rotated through the transmission chain 33, and the driving gears 32 drive the transmission When the moving chain 33 slides on the inner wall of the arc plate 3, the transmission chain 33 is connected with the transmission gear 312 through the connecting hole on the chain, so that the transmission chain 33 can simultaneously drive the corresponding plurality of rotating rods 31 to rotate through the transmission gear 312, and the rotating rod 31 drives the corresponding two pipe support rollers 311 to rotate, so that the pipe support roller 311 obtains a power source for driving the pipe to rotate, and the anti-skid layer 313 increases the friction between the pipe support roller 311 and the pipe, so as to facilitate the driving and limiting work of the pipe support roller 311 on the pipe.

[0021] The inner walls of the four arc plates 3 are fixedly connected with arc partition plates 34 for limiting the transmission chain 33. The transmission chain 33 is slidably connected to the corresponding side walls of the arc partition plates 34. One side of the arc partition plates 34 is provided with a plurality of make way grooves 341 for making way for the pipe support rollers 311. The driving gear 32 does not contact the arc partition plates 34. The arc partition plates 34 limit the middle space of the transmission chain 33 to prevent the transmission chain 33 from interlaced contact and affecting the transmission effect. The arc partition plates 34 make way for the transmission teeth 312 through the make way grooves 341 to prevent the arc partition plates 34 from interfering with the rotation of the transmission teeth 312, and the driving gear 32 will not be interfered by the arc partition plates 34.

[0022] One side of each of the four arc plates 3 is fixedly connected with a limit block 35 for limiting the angle of the arc plate 3, and the limit block 35 contacts the top of the corresponding U-shaped support base 2, and one side of each of the four arc plates 3 is installed with a drive motor 36 corresponding to the drive gear 32; the limit block 35 is located on the outside of the arc plate 3, and when the pipeline is lifted up and taken out after cutting, the torsion spring drives the arc plate 3 to flip upward, and the arc plate 3 drives the limit block 35 to flip toward the U-shaped support base 2, and then the limit block 35 contacts the top of the U-shaped support base 2 and is limited by the U-shaped support base 2, so that the arc plate 3 cannot be flipped at this time, preventing the arc plate 3 from flipping excessively, and the drive motor 36 does not contact the pipeline, and the drive motor 36 drives one of the drive gears 32 to rotate.

[0023] A spring 51 is arranged between the limiting wedge rod 5 and the corresponding U-shaped supporting base frame 2. One end of the limiting wedge rod 5 is fixedly connected to a traction rope 52 for unlocking the connecting plate 4, and the spring 51 does not contact the traction rope 52; the spring 51 pushes the corresponding limiting wedge rod 5, so that the limiting wedge rod 5 can be stably plugged into the limiting groove 41 for limiting work. The traction rope 52 works in opposite directions to the spring 51. By pulling the traction rope 52, the traction rope 52 can pull the corresponding limiting wedge rod 5 into the U-shaped supporting base frame 2 and retract it, so that the limiting wedge rod 5 can be disengaged from the limiting groove 41, and then the pipeline is lifted, and the pipeline squeezes and flips the arc plate 3 upward, so that the space between the two arc plates 3 is automatically opened, which is convenient for taking out the pipeline after cutting.

[0024] The four traction ropes 52 are all slidably connected to the corresponding inner wall of the U-shaped support base 2. A winder 53 corresponding to the traction rope 52 is installed on the inner wall of the U-shaped support base 2. The winder 53 is used to wind up the corresponding two traction ropes 52; the U-shaped support base 2 provides external protection for the winder 53, and the winder 53 winds up the two traction ropes 52 by rotating the output shaft. The traction rope 52 slides in the internal track of the U-shaped support base 2. When the traction rope 52 is wound by the winder 53, the limit wedge rod 5 is pulled, so that the limit wedge rod 5 can unlock the connecting plate 4.

[0025] The working principle and use process of the utility model are as follows: when cutting the oil pipeline, the four arc plates 3 are divided into two groups and are in an unfolded state driven by the torsion spring, so that the pipeline can fall down and enter. Then the pipeline presses down and flips the arc plate 3, and the arc plate 3 drives the corresponding connecting plate 4 to rotate in the direction of the slot 21. Then the connecting plate 4 is inserted into the corresponding slot 21. When the arc plate 3 contacts the arc-shaped inner wall of the U-shaped support frame 2, the spring 51 pushes the limiting wedge rod 5 to extend in the direction of the connecting plate 4, and the limiting wedge rod 5 is inserted into the limiting groove 41, so as to limit the connecting plate 4 and prevent the connecting plate 4 from detaching from the slot 21, so that the connecting plate 4 can limit the arc plate 3, thereby enabling the four arc plates 3 to clamp the pipeline. The fixation becomes more stable, preventing the pipeline from shaking and detaching during the cutting process. Subsequently, the pipeline is cut, and several driving motors 36 are controlled to drive the corresponding driving gears 32 to rotate. The driving gears 32 drive the transmission chain 33 to slide on the inner wall of the arc plate 3. The transmission chain 33 can simultaneously drive the corresponding several rotating rods 31 to rotate through the transmission teeth 312. The rotating rods 31 drive the corresponding two pipeline support rollers 311 to rotate. The pipeline support rollers 311 drive the pipeline to rotate, so that different angles of the pipeline can be rotated to the bottom corresponding to the cutting component, thereby facilitating the cutting work of the cutting component on the pipeline. There is no need to unlock the limit of the pipeline and then rotate it. The operation is more convenient and quick, and the work efficiency is further improved.
