Description

Technical Field

[0001] This application relates to the technical field of steel pipe production equipment, and in particular to a steel pipe transmission support device. Background Technology

[0002] Steel pipe cutting is a common process in metal processing, widely used in construction, machinery manufacturing, petrochemicals, and other fields. With industrial development, the applications of steel pipes are becoming increasingly diverse, and the requirements for cutting precision and efficiency are also rising. Currently, steel pipe cutting equipment mainly includes stationary cutting machines and mobile cutting machines. Stationary cutting machines are mostly used for mass production, while mobile cutting machines are suitable for on-site operations. However, regardless of the cutting method, the support of the steel pipe remains a key factor affecting cutting quality and efficiency. Traditional support devices are mostly of fixed dimensions, making it difficult to adapt to the cutting needs of steel pipes of different diameters. This leads to problems such as vibration and misalignment during the cutting process, affecting cutting precision and equipment lifespan. Utility Model Content

[0003] In order to meet the support requirements for steel pipes of different diameters and improve the applicability of the device, this application provides a steel pipe transmission support device.

[0004] The steel pipe transmission support device provided in this application adopts the following technical solution:

[0005] A steel pipe conveying support device includes a connecting seat, a support roller, and a locking assembly. The support roller is rotatably connected to the connecting seat, and the axis of rotation of the support roller is horizontal. The outer circumference of the support roller is provided with a plurality of grooves, the groove walls of which are used to fit against the outer wall of the steel pipe. The plurality of grooves are distributed at intervals around the axis of rotation of the support roller, and the grooves are arc-shaped. The radius of any one of the grooves is different. The locking assembly is connected between the connecting seat and the support roller to achieve relative fixation of the connecting seat and the support roller.

[0006] By adopting the above technical solution, several arc-shaped grooves with different radii are set on the outer periphery of the support roller, which can adapt to steel pipes of different diameters and meet the support requirements for steel pipes of different diameters. The groove wall fits in close contact with the outer wall of the steel pipe, reducing the possibility of vibration or displacement of the steel pipe during the cutting process and improving the reliability and applicability of the device.

[0007] Preferably, the distance from the center of any of the groove cross sections to the rotation axis of the support roller is equal, and all the grooves are connected.

[0008] By adopting the above technical solution, all grooves are connected, which can accommodate steel pipes of various diameters and improve the applicability of the device.

[0009] Preferably, the locking assembly includes a limiting post and a first reset member. The limiting post is slidably connected to the connecting seat, and the sliding direction of the limiting post is parallel to the rotation axis of the support roller. The end of the support roller near the limiting post is provided with a plurality of limiting holes, which are spaced apart around the rotation axis of the support roller. The limiting holes are used for the limiting post to be inserted into. The distance from the axis of any limiting hole to the rotation axis of the support roller is equal to the distance from the axis of the limiting post to the rotation axis of the support roller. The first reset member is connected between the limiting post and the connecting seat, and the first reset member makes the limiting post tend to be inserted into the limiting hole.

[0010] By adopting the above technical solution, the operator pulls the limiting post to overcome the elastic force of the first reset member and disengage from the limiting hole, thereby releasing the lock of the connecting seat and the support roller. When the corresponding limiting hole is aligned with the limiting post, the operator releases the limiting post, and the limiting post is embedded in the limiting hole under the action of the elastic force of the first reset member, thereby locking the connecting seat and the support roller, reducing the possibility of the support roller rotating during the steel pipe cutting process, and improving the reliability of the device.

[0011] Preferably, the support roller has a scale line at one end near the limiting hole.

[0012] By adopting the above technical solution, a scale line is set at one end of the support roller near the limiting hole, which makes it easy for operators to intuitively display the diameter of the groove at the contact point between the support roller and the steel pipe, ensuring that the groove wall fits in close contact with the outer wall of the steel pipe, reducing the possibility of the steel pipe moving relative to the support roller along the rotation axis of the support roller, and improving the reliability of the device.

[0013] Preferably, it further includes a fixed base and a drive cylinder, wherein the connecting base is slidably connected to the fixed base and the sliding direction of the connecting base is vertical, and the drive cylinder is connected to the fixed base and is used to drive the connecting base to slide.

[0014] By adopting the above technical solution and setting a drive cylinder, the connecting seat can be pushed to slide as needed, thereby driving the steel pipe to slide in the vertical direction to adapt to different processing heights and improve the applicability of the device.

[0015] Preferably, the lower end of the connecting seat is connected to a plurality of guide posts, which are divided into two groups. The two groups of guide posts are symmetrically distributed along the rotation axis of the support rollers. The plurality of support rollers in the same group are distributed at intervals along a direction perpendicular to the rotation axis of the support rollers. The fixed seat is provided with guide holes. The number of guide holes is the same as the number of guide posts and corresponds one-to-one. The guide posts are coaxially slidably embedded in the guide holes, and the outer wall of the guide posts is in contact with the wall of the guide holes.

[0016] By adopting the above technical solution, a number of guide posts are connected to the lower end of the connecting seat. The guide posts are coaxially slidably embedded in the guide holes, and the outer wall of the guide posts is in contact with the wall of the guide holes. This improves the stability of the connecting seat when sliding in the vertical direction, improves the stability of the connection between the connecting seat and the fixed seat, and improves the reliability of the device.

[0017] Preferably, the connecting seat includes a base body and a connecting frame. One end of the connecting frame is connected to the base body. There are two connecting frames, which are symmetrically distributed along the rotation axis of the support roller. The two ends of the support roller are rotatably connected to the two connecting frames respectively.

[0018] By adopting the above technical solution, the connecting seat consists of a seat body and two connecting frames. The two connecting frames are symmetrically distributed along the rotation axis of the support roller. The two ends of the support roller are rotatably connected to the two connecting frames respectively. The detachable connecting frames and seat body enable the maintenance and replacement of the connecting seat or support roller, thereby improving the service life of the device.

[0019] Preferably, the support roller is provided with a weight-reducing groove, which passes through the support roller along the rotation axis of the support roller.

[0020] By adopting the above technical solution, the support roller is equipped with a weight reduction groove, which reduces the weight of the support roller while ensuring the structural strength of the support roller. This reduces the gravity on the connecting seat, reduces the possibility of the connecting seat bending or breaking due to excessive force, and improves the service life of the connecting seat, as well as the service life and reliability of the device.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The outer circumference of the support roller is provided with several arc-shaped grooves of different radii, which can adapt to steel pipes of different diameters and meet the support requirements of steel pipes of different diameters. The groove wall fits in close contact with the outer wall of the steel pipe, reducing the possibility of vibration or displacement of the steel pipe during the cutting process and improving the reliability and applicability of the device.

[0023] 2. The operator pulls the limiting post to overcome the elastic force of the first reset piece and disengage from the limiting hole, thereby releasing the lock of the connecting seat and the support roller. The operator rotates the support roller, and when the corresponding limiting hole is aligned with the limiting post, the operator releases the limiting post. Under the action of the elastic force of the first reset piece, the limiting post is embedded in the limiting hole, thereby locking the connecting seat and the support roller, reducing the possibility of the support roller rotating during the steel pipe cutting process, and improving the reliability of the device.

[0024] 3. A drive cylinder is provided, which can push the connecting seat to slide as needed, thereby driving the steel pipe to slide vertically to adapt to different processing heights and improve the applicability of the device. Attached Figure Description

[0048] Pulling the handle 33 causes the limiting post 31 to overcome the elastic force of the first reset member 32 and disengage from the limiting hole 22. Rotating the support roller 2 causes the groove 21 of the corresponding radius to be at the top. Releasing the handle 33 causes the limiting post 31 to slide close to the support roller 2 under the action of the elastic force of the first reset member 32. The first chamfer 311 abuts against the wall of the limiting hole 22, and the limiting post 31 is embedded in the limiting hole 22. The support roller 2 and the connecting seat 1 are circumferentially fixed. Pulling the rotating frame 63 overcomes the elastic force of the second reset member 64, and the steel pipe slides into the groove 21. Releasing the rotating frame 63 causes the pressing roller 61 to rotate close to the support roller 2 under the action of the elastic force of the second reset member 64. The wall of the pressing groove 611 abuts against the outer wall of the steel pipe.

[0049] When the height of the steel pipe needs to be adjusted, the drive cylinder 5 operates, causing the connecting seat 1 to slide.
