Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe sizing equipment, and in particular to an adjustable support device for a steel pipe sizing machine. Background Technology

[0002] The pipe support device of the pipe sizing machine is a key component to ensure the stable operation of the steel pipe during the sizing process. It bears the weight of the steel pipe, prevents the steel pipe from deforming or sagging due to its own weight, which would affect the sizing accuracy, and ensures that the steel pipe maintains the correct position and posture between the sizing rollers, so that the sizing process can proceed smoothly.

[0003] While some existing steel pipe sizing machine support devices can adjust the support height according to the steel pipe diameter, the included angle between the two conveying rollers cannot be flexibly changed when dealing with steel pipes of different diameters. When conveying steel pipes with larger diameters, if the included angle of the conveying rollers is fixed and large, the steel pipe is difficult to be stably limited and supported during the conveying process, and is prone to shaking and deviation. This not only affects the conveying stability of the steel pipe, but also leads to uneven stress on the steel pipe during the sizing process. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable support device for a steel pipe sizing machine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable support device for a steel pipe sizing machine includes a base with multiple partitions fixedly mounted on it. A motor is fixedly mounted on one side of one of the partitions and is electrically connected to an external main controller via a cable. An adjusting shaft is rotatably connected between the partitions, and one end of the adjusting shaft is fixedly connected to the output end of the motor via a coupling. Two guide rails are also fixedly mounted on the base between two partitions, and two mounting seats are provided on the two guide rails. Two sliders are fixedly mounted on the lower ends of the two mounting seats, and the sliders are slidably connected to the corresponding guide rails. Support arms are rotatably mounted on both sides of the two mounting seats, and the two support arms on the same side of the two mounting seats are cross-connected via a connecting shaft. Support rollers are movably connected to the opposite sides of the two support arms, and first shaft seats are movably connected to the opposite sides of the two support rollers.

[0007] As a further preferred embodiment of this utility model, a fixed seat is fixedly installed at the middle position of one side of the mounting base, and a second shaft seat is fixedly installed on the fixed seat. The setting of the second shaft seat can provide a basic support point for adjusting the height of the first shaft seat.

[0008] As a further preferred embodiment of this utility model, two third bearings are fixedly installed on the upper end of the support arm, and a first rotating shaft is rotatably connected between the two third bearings. The support arm is provided with two third bearings, and the first rotating shaft is provided between the two third bearings, which can provide installation conditions for one end of the support roller.

[0009] As a further preferred embodiment of the present invention, a second rotating shaft is rotatably mounted on one end of the support roller, and a third rotating shaft is rotatably mounted on the other end of the support roller. The second rotating shaft is also inserted into a shaft hole inside the first rotating shaft.

[0010] As a further preferred embodiment of this utility model, two fourth rotating shafts are rotatably connected inside the first shaft seat, and the third rotating shaft is inserted and installed on the fourth rotating shaft through the internal shaft hole. The fourth rotating shafts located on both sides of the third rotating shaft are each fitted with a retaining spring. The second rotating shaft at one end of the support roller is inserted and installed inside the first rotating shaft, while the third rotating shaft is inserted and installed on the fourth rotating shaft. This provides a basis for automatic adjustment of the support angle between the two support rollers when the support arm drives the support roller and the first shaft seat to change height.

[0011] As a further preferred embodiment of this utility model, two fourth shaft seats are fixedly installed at the lower end of the first shaft seat, and a support rod is movably connected between the fourth shaft seat and the second shaft seat.

[0012] As a further preferred embodiment of this utility model, both ends of the support rod are fixedly installed with fixed shafts, and one end of the fourth shaft seat is rotatably installed in the fourth shaft seat through the fixed shaft, while the other end of the support rod is rotatably installed in the second shaft seat through the corresponding fixed shaft. When the two mounting seats slide on the two guide rails, the height of the upper ends of the two cross-connected support arms will change, so that the support roller, together with the first shaft seat and the support rod, can adjust the support angle according to the pipes of different diameters.

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

[0014] In this invention, when the two sets of mounting seats and sliders move relative to each other or in opposite directions via the adjusting shaft, the two mounting seats can drive the upper ends of the four cross-connected support arms to adjust their height. Furthermore, the two support rollers, together with the first shaft seat, the first rotating shaft, and the support rod, can automatically adjust the support angle of the two support rollers according to the different pipe diameters. This allows for the provision of conveying support height for pipes of different diameters, and the stability of pipe support and conveying can be improved by adjusting the angle of the two support rollers.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-4 As shown, the present invention provides an adjustable support device for a steel pipe sizing machine, comprising a base 1, on which multiple partitions 2 are fixedly installed. A motor 3 is fixedly installed on one side of one of the partitions 2, and the motor 3 is electrically connected to an external main controller via a cable. An adjusting shaft 4 is rotatably connected between the multiple partitions 2, and one end of the adjusting shaft 4 is fixedly connected to the output end of the motor 3 via a coupling. Two guide rails 5 are also fixedly installed on the base 1 between two partitions 2, and two mounting seats 6 are provided on the two guide rails 5. Two sliders 7 are fixedly installed at the lower ends of the two mounting seats 6 respectively. The sliders 7 are slidably connected to the corresponding guide rails 5. Support arms 8 are rotatably installed on both sides of the two mounting seats 6, and the two support arms 8 on the same side of the two mounting seats 6 are cross-connected via a connecting shaft 9. Support rollers 10 are movably connected to the opposite side of the two support arms 8, and first bearing seats 11 are movably connected to the opposite side of the two support rollers 10.

[0022] like Figures 2-4As shown, two third bearing seats 14 are fixedly installed on the upper end of the support arm 8. A first rotating shaft 15 is rotatably connected between the two third bearing seats 14. The support arm 8 is provided with two third bearing seats 14, and the first rotating shaft 15 is provided between the two third bearing seats 14, which can provide installation conditions for one end of the support roller 10. A second rotating shaft 16 is rotatably installed on one end of the support roller 10, and a third rotating shaft 17 is rotatably installed on the other end of the support roller 10. The second rotating shaft 16 is also inserted into the shaft hole in the first rotating shaft 15. The first bearing seat 11 is located inside the shaft hole. Two fourth rotating shafts 18 are rotatably connected, and a third rotating shaft 17 is inserted and installed on the fourth rotating shaft 18 through an internal shaft hole. The fourth rotating shafts 18 located on both sides of the third rotating shaft 17 are each fitted with a retaining spring. A second rotating shaft 16 at one end of the support roller 10 is inserted and installed in the first rotating shaft 15, while the third rotating shaft 17 is inserted and installed on the fourth rotating shaft 18. This provides a basis for automatic adjustment of the support angle between the two support rollers 10 when the support arm 8 drives the support roller 10 and the first shaft seat 11 to change height.

[0023] like Figures 1-4 As shown, two fourth shaft seats 19 are fixedly installed at the lower end of the first shaft seat 11. A support rod 20 is movably connected between the fourth shaft seat 19 and the second shaft seat 13. A fixed seat 12 is fixedly installed at the middle position of one side of the mounting seat 6. The second shaft seat 13 is fixedly installed on the fixed seat 12. The setting of the second shaft seat 13 can provide a basic support point for adjusting the height of the first shaft seat 11. Fixed shafts 21 are fixedly installed at both ends of the support rod 20. One end of the fourth shaft seat 19 is rotatably installed in the fourth shaft seat 19 through the fixed shaft 21, and the other end of the support rod 20 is rotatably installed in the second shaft seat 13 through the corresponding fixed shaft 21. When the two mounting seats 6 slide on the two guide rails 5, the height of the upper end of the two cross-connected support arms 8 will change, so that the support roller 10 can cooperate with the first shaft seat 11 and the support rod 20 to adjust the support angle according to the pipe with different diameters.

[0024] It should be noted that this utility model is an adjustable support device for a steel pipe sizing machine. When using this adjustable support device, it is first installed in the corresponding position on the steel pipe sizing machine. When it is necessary to adjust the support height of the support roller 10 according to steel pipes of different diameters, the external main controller sends a command to the motor 3, the motor 3 starts, and its output end drives the adjusting shaft 4 to rotate. Because the adjusting shaft 4, located between the two partitions 2, is provided with left-hand and right-hand threaded sections and is threadedly connected to the corresponding mounting seats 6, and because the slider 7 at the lower end of the mounting seat 6 is slidably connected to the guide rail 5, the two mounting seats 6 will move relative to or in opposite directions on the guide rail 5. When the mounting seat 6 moves, the support arm 8 connected to it will move. Because the support arms 8 on the same side of the two mounting seats 6 are cross-connected by the connecting shaft 9, the movement of the mounting seat 6 will... The height of the upper end of the support arm 8 changes, and a third bearing 14 is fixed at the upper end of the support arm 8. A first rotating shaft 15 is rotatably connected between the two third bearings 14. A second rotating shaft 16 at one end of the support roller 10 is inserted into the first rotating shaft 15, and a third rotating shaft 17 at the other end is inserted into the fourth rotating shaft 18 in the first bearing 11. When the height of the support arm 8 changes, the support roller 10 and the first bearing 11 move accordingly. At the same time, the fourth bearing 19 at the lower end of the first bearing 11 is movably connected to the second bearing 13 of the fixed seat 12 on the mounting seat 6 through a support rod 20. The movement of the mounting seat 6 causes the height of the support arm 8 to change, thereby enabling the support roller 10 to cooperate with the first bearing 11 and the support rod 20 to automatically adjust the support angle according to the diameter of the steel pipe, stably support steel pipes of different diameters, and ensure that the steel pipe maintains the correct position and posture during the sizing process.
