A support plate capable of controlling the movement of the tire is provided at the lower end of the straightening device base, and a threaded rod is rotatably mounted at the upper end of the support plate. In this invention, the force of the straightening device base is transmitted to the clamping plate, the clamping plate is transmitted to the rotating shaft, the rotating shaft is transmitted to the C-shaped plate, and the C-shaped plate is transmitted to the tire. The tire rolls on the ground. When the straightening device base needs to turn, it will drive the C-shaped plate to rotate at the lower end of the clamping plate through the rotating shaft. By setting four tires at the lower end of the straightening device base, the mobility of the straightening device base is improved.

[0004] However, the present invention has the following problems in actual use;

[0005] The existing device's design, which facilitates mobility, can lead to reduced stability during actual beam alignment operations.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Example 1;

[0029] Please see Figures 1 to 6To facilitate the correction of deformed vehicle beams, this utility model provides a technical solution: a mobile anti-collapse beam correction device. This mobile anti-collapse beam correction device is mainly used in the scenario of correcting damaged vehicles. It includes a base 1 and a support foot 2. A slider 8 for movement is snapped onto the side of the base 1. A hydraulic correction column 9 is threaded onto the upper end of the slider 8. A positioning pin 10 for fixing is inserted into the upper end of the slider 8. The positioning pin 10 passes through one side of the slider 8 and is threaded onto the inner wall of the base 1. A chain 11 is provided at the upper end of the hydraulic correction column 9. A hook 12 for limiting is fixedly connected to one end of the chain 11. A universal wheel 3 for movement is snapped onto the lower end of the support foot 2.

[0030] The slider 8 allows for more convenient adjustment of the position of the hydraulic straightening column 9 to achieve the appropriate position. By sliding the slider 8, the lateral position of the hydraulic straightening column 9 can be adjusted, so that the straightening force can be accurately applied to the position of the beam that needs to be straightened. When the slider 8 moves to the appropriate position, the positioning pin 10 is inserted into the inner wall of the base 1 to fix and limit the slider 8, preventing the slider 8 from sliding when the hydraulic straightening column 9 is working, and ensuring that the hydraulic straightening column 9 can stably straighten the beam. With the help of the hook 12, it can hook the vehicle beam or the clamp connected to the beam. At the same time, the hydraulic straightening column 9 generates a strong pushing or pulling force, which is transmitted through the chain 11, so that the hook 12 can accurately calibrate the deformed beam.

[0031] Example 2;

[0032] Please see Figures 2 to 6 To facilitate placing the vehicle on the upper part of the base 1, the upper part of the support foot 2 is connected to an adjustment shaft 4, and one end of the shaft 4 is threaded to a support foot 5. The side of the base 1 is fixedly connected to an auxiliary plate 18 for limiting the position. The upper part of the auxiliary plate 18 is provided with friction texture for anti-slip. The upper part of the support foot 5 is connected to a threaded post 6 for fastening. With the help of the auxiliary plate 18, it plays a role in auxiliary support and limiting the position, making it easier for staff to transport the damaged vehicle to the upper part of the base 1.

[0033] Example 3;

[0034] Please see Figures 1 to 4To facilitate easier height adjustment of the placement box 14 and enable its clamping plate 15 to fix and limit different vehicles, a limiting post 7 for support is inserted into the upper end of the base 1. A telescopic rod 13 for adjustment is inserted into the upper end of the limiting post 7. The upper end of the telescopic rod 13 is bolted to the placement box 14 for positioning. A clamping plate 15 for fixation is snapped into the inner wall of the placement box 14. A stepper motor 16 is inserted into the side of the clamping plate 15. A fastening post 17 for fixation is inserted into the side of the limiting post 7, and the fastening post 17 penetrates one side of the limiting post 7. The side thread is connected to the inner wall of the telescopic rod 13. By adjusting the height of the telescopic rod 13, the position of the placement box 14 can be changed to achieve a suitable height. The clamping plate 15 is snapped into the inner wall of the placement box 14 to fix the beam. The driving force generated by the stepper motor 16 drives the clamping plate 15 to rotate, thereby clamping the beam tightly to prevent the beam from shifting during the calibration process and ensuring the smooth progress of the calibration work. With the help of the fastening column 17, the telescopic rod 13 can be fixed and limited after it is adjusted to a suitable height.

[0035] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0036] In this invention, the working steps of the device are as follows:

[0037] First, using the casters 3 attached to the lower end of the support leg 2, the entire beam straightening device is moved within the workshop or other work area. After being pushed to a suitable position, the bearing leg 5 is rotated downwards by turning the shaft 4 inserted at the upper end of the support leg 2 until the bearing leg 5 contacts the ground. Then, the threaded column 6 inserted at the upper end of the bearing leg 5 is used for tightening to firmly fix the bearing leg 5 to the ground, allowing the equipment to be stably placed on the ground by relying on the bearing leg 5. The operator places the vehicle on the upper end of the base 1 and uses the clamping plate 15 attached to the inner wall of the placement box 14 to fix the beam. The slider 8, which is attached to the side of the base 1, is slid to adjust the lateral position of the hydraulic straightening column 9 threaded at the upper end of the slider 8, so that the hydraulic straightening column 9 can be accurately aligned with the position of the beam that needs to be corrected. Then, the hook 12 hooks the vehicle beam and activates the hydraulic straightening column 9 to generate a strong pushing or pulling force, which is transmitted through the chain 11 to correct the deformed beam.
