[0002] The steel pipes produced by the front swing spiral welded pipe unit are transferred from the rear bridge of the unit to the steel pipe transmission roller. The industry generally uses a stand for transition connection. At this stage, the steel pipes are transported horizontally by rolling by the weight of the steel pipes using the slope of the stand grate and stop at the receiver at the end of the stand.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] The embodiment of the present application provides a steel pipe offline device, which can block the steel pipe in transit, reduce the transmission speed of the steel pipe to zero, and then retract the pipe blocking roller into the interior of the transition stand. The steel pipe will continue to be transported to the next steel pipe transmission roller due to gravity, thereby playing a buffering role in the rolling of the steel pipe offline; it not only reduces the impact noise of the steel pipe, but also increases the life of the steel pipe and reduces maintenance costs.

[0038] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a steel pipe offline device, which may include: a transition stand 1, the transition stand 1 having a working surface 11, and the working surface 11 is inclined; a base 2, the base 2 is installed on the transition stand 1, and the base 2 is hinged with a pipe-blocking roller 3; a first telescopic driving member, the first telescopic driving member is installed on the base 2 and connected to the pipe-blocking roller 3, the first telescopic driving member can drive the pipe-blocking roller 3 to swing to expose the working surface 11, so that the pipe-blocking roller 3 is against the pipe body 4 on the transition stand 1.

[0039] Exemplarily, the working surface 11 can be arranged to be higher on the left and lower on the right, the base 2 can be located inside the transition platform 1, one end of the first telescopic drive member is hinged to the base 2, and the other end thereof is hinged to the tube-blocking roller 3; when the first telescopic drive member is extended, it can push the tube-blocking roller 3 to rotate clockwise and expose the outside of the working surface 11 to block the tube body 4 transported from the rear; when the first telescopic drive member is contracted, it can drive the tube-blocking roller 3 to rotate counterclockwise and retract to the bottom of the working surface 11, and at this time the tube body 4 continues to be transported under its own gravity.

[0040] Specifically, by adding an inclined transition stand 1 between the rear axle of the unit and the steel pipe transmission roller, the steel pipe can be easily transported without power by its own gravity. During the transmission process, due to the large drop, the steel pipe transmission speed is relatively fast. At this time, the first telescopic drive member can be started to drive the pipe blocking roller 3 to swing out of the top of the transition stand 1, blocking the steel pipe in transit, so that the transmission speed of the steel pipe is zero, and then the pipe blocking roller 3 is retracted into the interior of the transition stand 1. The steel pipe continues to be transported to the next steel pipe transmission roller due to gravity, playing a buffering role for the rolling of the steel pipe offline; it not only reduces the impact noise of the steel pipe, but also increases the life of the steel pipe and reduces the maintenance cost. It solves the problem that the traditional steel pipe stops at the receiver at the terminal of the stand, which is easy to cause damage to the surface of the steel pipe, and the impact noise with the receiver is large, which is harmful to the occupational health of employees.

[0041] In some embodiments, such as Figure 1 and Figure 2As shown, the steel pipe offline device may also include: a first steel pipe detection sensor 5, which is installed on the side of the transition platform 1 and is used to detect the steel pipe behind the pipe-blocking roller 3; a controller, which is electrically connected to the first steel pipe detection sensor 5 and the first telescopic drive member; the base 2, the pipe-blocking roller 3, the first telescopic drive member and the first steel pipe detection sensor 5 form a group of pipe blockers, and the transition platform 1 is provided with multiple groups of pipe blockers along the conveying direction of the transition platform 1. Exemplarily, the first steel pipe detection sensor 5 may be a proximity switch, which is fixed to the side of the transition platform 1 by bolts and exposed to the outside of the transition platform 1, so that the pipe body 4 passing above it can be detected. When the first steel pipe detection sensor 5 can detect whether there is a pipe body 4 passing, if so, the controller will control the first telescopic drive member to drive the pipe-blocking roller 3 to rotate clockwise and expose it outside the working surface 11, so as to prepare to block the pipe body 4 conveyed from the rear. The number of the multiple sets of pipe stoppers is proportional to the length of the transition stand 1 . The greater the number of the multiple sets of pipe stoppers, the less force of the collision between the pipe body 4 and the pipe stop roller 3 .

[0042] Of course, in some embodiments, the first steel pipe detection sensor 5 can also be a pressure sensor. When the tube body 4 reaches the position of the first steel pipe detection sensor 5, the first steel pipe detection sensor 5 will be squeezed to generate an electrical signal. The controller receives the electrical signal to determine whether there is a tube body 4 passing by.

[0043] In some embodiments, Figure 1 and Figure 2As shown, the steel pipe offline device can also include: two pipe-blocking rods 6, which are spaced apart along the width direction of the transition platform 1 and are located in front of the transition platform 1, and the two pipe-blocking rods 6 are hinged to the transition platform 1, and a V-shaped groove 61 is provided on one side of the pipe-blocking rod 6, and the V-shaped groove 61 is used to receive the pipe body 4; a second telescopic driving member, which is installed on the transition platform 1 and hinged to the pipe-blocking rod 6, and the second telescopic driving member can drive the pipe-blocking rod 6 to swing, so that the pipe body 4 in the V-shaped groove 61 slides out; a second steel pipe detection sensor 7, which is installed on the pipe-blocking rod 6 and is used to detect the pipe body 4 on the pipe-blocking rod 6; the second telescopic driving member and the second steel pipe detection sensor 7 are both electrically connected to the controller. Exemplarily, one end of the second telescopic driving member can be fixed to the transition platform 1, and the other end thereof can be connected to the two tube-stopping rods 6 via a connecting rod arranged in the front-to-back direction, that is, the other end of the second telescopic driving member is hinged with a connecting rod, and the two ends of the connecting rod are fixed to the two tube-stopping rods 6. When the second telescopic driving member is extended, the two tube-stopping rods 6 are pushed to rotate counterclockwise to hold the tube body 4 in the V-shaped groove 61, or when the second telescopic driving member is driven to contract, the two tube-stopping rods 6 are pulled to rotate clockwise until the right end of the V-shaped groove 61 is tilted to the right, and the tube body 4 slides out of the V-shaped groove 61 under its own gravity to proceed to the next process. Among them, the second steel pipe detection sensor 7 can be a proximity switch. When the second steel pipe detection sensor 7 detects that the tube body 4 has fallen into the V-shaped groove 61, the controller will drive the tube blocking rod 6 to rotate clockwise to transport the tube body 4 in the V-shaped groove 61 out. When the second steel pipe detection sensor 7 detects that there is no tube body 4 in the V-shaped groove 61, it will control the tube blocking rod 6 to rotate counterclockwise to return to its original position and prepare to receive the next tube body 4.

[0044] Of course, in some embodiments, the second steel pipe detection sensor 7 may also be a pressure sensor, and the pressure sensor is installed on the inner bottom wall of the V-shaped groove 61 .

[0045] In some embodiments, the first telescopic driving member and the second telescopic driving member both include an electric push rod or a hydraulic push rod.

[0046] In some embodiments, a resistance pad is fixed to the inner wall of the V-shaped groove 61. The resistance pad is fixed to the inner wall of the V-shaped groove 61, which can reduce the sliding speed of the tube body 4 in the V-shaped groove 61, further ensuring the service life of the tube body 4 and the quietness of the working environment.

[0047] In some embodiments, a rubber sleeve is provided on the outer wall of the tube-blocking roller 3. The rubber sleeve can further ensure the service life of the tube body 4 and the quietness of the working environment.

[0048] In some embodiments, such as Figure 3As shown, the transition stand 1 may include: two grate bars 12, the two grate bars 12 are arranged in parallel, and the tops of the two grate bars 12 form a working surface 11; a plurality of piers 13, a plurality of piers 13 are fixed under each grate bar 12, and the plurality of piers 13 are distributed at intervals along the length direction of the grate bar 12, and the heights of the plurality of piers 13 gradually decrease along the length direction of the grate bar 12. Among them, the transition stand 1 has a simple structure and is easy to assemble, which reduces the cost of the steel pipe offline device.

[0049] In some embodiments, Figure 3 As shown, the transition stand 1 may further include a pad 14, and a pad 14 is fixed between the pier 13 and the grate bar 12. By changing the number of pads 14 between each pier 13 and the grate bar 12, the inclination of the grate bar 12 can be changed, that is, the inclination of the working surface 11 can be changed, so as to ensure that it can be adjusted in actual use.

[0050] In some embodiments, Figure 3 As shown, the transition stand 1 may further include: a stiffening plate 15, which is fixed to the higher end of the grate bar 12. The stiffening plate 15 is added near the left end of the grate bar 12 to improve the structural strength near the left end of the grate bar 12, because the left end of the grate bar 12 (that is, near the height end of the grate bar 12) is used to receive the pipe body 4 dropped from the high place of the previous process, and the structural strength of the left end of the grate bar 12 needs to be ensured here.

[0051] In some embodiments, the slope of the grate bars 12 is greater than or equal to 1.5°. Of course, in some embodiments, the slope of the grate bars 12 can be between 1.5° and 4.5°, which can be adjusted according to actual conditions, such as considering the size of the tube body 4.

[0052] In some embodiments, a resistance pad may be installed on the top of the grate bar 12 to further reduce the sliding speed of the tube body 4 .

[0053] The specific working process of this device is as follows: the tube body 4 falls from the left end of the grate bar 12, the oil cylinder or electric push rod of the first tube stopper does not move, and the tube body 4 rolls to the first tube stopper by its own weight and stops at the position. At this time, the first steel pipe detection sensor 5 at the next tube stopper detects that if there is a tube body 4, the oil cylinder of the first tube stopper does not move, and the tube body 4 does not roll. If it is detected that there is no tube body 4 at the next tube stopper, the oil cylinder or electric push rod of the first tube stopper moves to let the tube body 4 roll to the second tube stopper. At this time, the second steel pipe detection sensor 7 detects that there is no steel pipe, and the oil cylinder or electric push rod connected to the tube stopper rod 6 rises, and the oil cylinder or electric push rod at the second tube stopper moves to let the tube body 4 roll into the V-shaped groove 61, and then the oil cylinder or electric push rod connected to the tube stopper rod 6 drops to let the tube body 4 fall on the roller of the next process, and the roller is started to transport the tube body 4 away. If there is a tube body 4 on the second steel tube detection sensor 7, the second tube stopper oil cylinder or electric push rod does not move, and the steel tube is positioned there until the steel tube in the V-shaped groove 61 is completely transported away.
