[0002] In the production of precision steel pipes, a straightening machine must be used to straighten the pipes to meet the required straightness. Existing straightening machines typically involve supporting the pipe on top of a moving roller, then manually pushing the roller to move the pipe directly under the straightening machine. The pipe also needs to be manually rotated during the straightening process. This traditional manual straightening process, using a hand-pushed straightening trolley, is labor-intensive and inefficient. Utility Model Content

[0003] The purpose of this invention is to provide an electric straightening trolley for steel pipes. This straightening trolley can be used for the auxiliary straightening of steel pipes. During the straightening process, it allows the steel pipes to move and rotate freely, replacing the traditional manual rotation and movement process, reducing labor intensity, and improving work efficiency.

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1-4As shown, the electric straightening trolley for steel pipes includes a movable frame 7, on which a first axle 6 and a second axle 11 are mounted in parallel. Track wheels 9 are mounted at both ends of the first axle 6 and the second axle 11, and the track wheels 9 are connected to a mobile power device for driving their rotation. A synchronous drive device is installed between the track wheels 9 on the first axle 6 and the second axle 11. A support column 15 is mounted on the top of the first axle 6 and the second axle 11, and a top frame 12 is mounted on the top of the support column 15 via a flexible telescopic mechanism. A roller mechanism for rolling support of the steel pipe is installed in the middle of the top of the top frame 12. This straightening trolley can be used for auxiliary straightening of steel pipes. During the straightening process, the steel pipe can move and rotate freely, replacing the traditional manual rotation and movement process, reducing labor intensity and improving work efficiency. In specific use, the steel pipe to be straightened is supported by the roller mechanism, and its angle is adjusted. Then, the mobile power device drives the entire device to move along the track, thereby changing the straightening position.

[0030] Furthermore, the mobile power device includes a first motor 1, which is fixed to the top of the front frame 3 via a motor base. The front frame 3 is fixed to the head side of the mobile frame 7. A drive sprocket 2 is mounted on the output shaft of the first motor 1. The drive sprocket 2 is driven by a first chain 4 meshing with a double-row sprocket 5. The double-row sprocket 5 is correspondingly mounted on a track wheel 9 on a first axle 6. This mobile power device provides the power for the trolley to move, thereby driving the entire trolley to move on the track, thus changing the position of the steel pipe to achieve straightening of the required position. During operation, the first motor 1 drives the drive sprocket 2, which in turn drives the first chain 4. The first chain 4 drives the double-row sprocket 5, which in turn drives the track wheel 9. The track wheel 9 supports the track, thus enabling the entire trolley to move.

[0031] Furthermore, the synchronous drive device includes a second chain 8, which meshes with both the double-row sprocket 5 and the driven sprocket 10. The driven sprocket 10 is correspondingly mounted on the track wheel 9 on the second wheel axle 11. This synchronous drive device ensures that the moving power device can synchronously drive the track wheel 9 located on the second wheel axle 11, guaranteeing that the front and rear track wheels 9 rotate synchronously. During operation, the double-row sprocket 5 drives the second chain 8, which in turn drives the driven sprocket 10, which in turn drives the track wheel 9. The track wheel 9 then engages with the track, thereby achieving synchronous movement.

[0032] Furthermore, the flexible telescopic mechanism includes a sleeve 16 disposed on the top of the top frame 12. The sleeve 16 is fixed to the top of the top frame 12 by a connecting plate 14 and a connecting bolt 13. The top of the support column 15 is slidably limited and installed inside the sleeve 16. A spring 17 is disposed inside the sleeve 16 and located at the top of the support column 15. A compression plate 18 is disposed at the top of the spring 17 and is slidably disposed inside the sleeve 16. An adjusting screw 19 is installed on the top cover of the sleeve 16 via a threaded drive. The bottom end of the adjusting screw 19 contacts and engages with the top end of the compression plate 18. The above-mentioned flexible telescopic mechanism can realize the flexible lifting support of the entire top frame 12, thereby playing a certain buffering role. During operation, when the steel pipe applies gravity to the entire top frame 12, the adjusting screw 19 is pressed by the sleeve 16, and the spring 17 is pressed by the adjusting screw 19. The compression of the spring 17 thereby realizes the flexible support of the entire top frame 12. Furthermore, the stiffness of the support force can be adjusted by adjusting the screw 19.

[0033] Furthermore, there are four sets of flexible telescopic mechanisms, which are correspondingly arranged and installed at the four top corners of the top frame 12. The above-mentioned four sets of flexible telescopic mechanisms ensure the stability and reliability of the support for the top frame 12.

[0034] Furthermore, the roller mechanism includes a rectangular box 22 fixed to the top frame 12. Parallel roller shafts 20 are rotatably mounted inside the rectangular box 22. Rollers 24 and gears 25 are respectively mounted on the two roller shafts 20 via flat keys 23. The gears 25 are connected to a roller rotation mechanism that provides rotational power. This roller mechanism enables rotational support for the steel pipe to be straightened. During operation, the gears 25 synchronously drive the roller shafts 20, which in turn drive the rollers 24. The rollers 24 then synchronously rotate the steel pipe supporting the top, thereby adjusting its angle.

[0035] Furthermore, the roller shaft 20 is rotatably supported on the rectangular housing 22 by bearing 21. Through the above...

[0036] Furthermore, the roller rotation mechanism includes a second motor 26, which is fixed to the top of the top frame 12. A drive gear 27 is mounted on the output shaft of the second motor 26, and the drive gear 27 simultaneously meshes with two sets of gears 25 for transmission. This roller rotation mechanism provides rotational power. During operation, the second motor 26 drives the drive gear 27, which in turn synchronously drives the gears 25, thereby synchronously driving the roller shaft 20 to rotate.

[0037] Furthermore, the bottom end of the support column 15 is provided with a threaded post 28, which is fixedly connected to a nut seat 29. The nut seat 29 is fixed on the corresponding first wheel axle 6 and second wheel axle 11. Through the cooperation between the threaded post 28 and the nut seat 29, reliable support and fixation of the support column 15 can be achieved.

[0038] Example 2:

[0039] The method for using the electric straightening trolley for steel pipes includes the following steps:

[0040] Step 1, Arrangement and installation of the alignment trolley:

[0041] Multiple straightening trolleys are rolled and supported on the track of the straightening machine;

[0042] Step 2, Placement of the steel pipe to be straightened:

[0044] Step 3, move the position of the steel pipe to be straightened:

[0045] According to the part to be straightened, start the mobile power device, which drives the entire straightening trolley to move on the track, thereby moving the steel pipe to be straightened directly under the pressure head of the straightening machine;

[0046] Step 4, Adjusting the angle of the steel pipe to be straightened:

[0047] According to the straightening direction of the steel pipe to be straightened, the roller mechanism is started, and the roller mechanism drives the roller 24, which in turn drives the steel pipe at the top to rotate, thereby rotating the steel pipe to the required angle.

[0048] Step 5, Press-fitting and straightening of the steel pipe to be straightened:

[0049] After the position and angle of the steel pipe are adjusted, start the straightening machine to straighten the steel pipe.
