Description

Technical Field

[0001] This utility model relates to a device for correcting and preventing deformation of the circular rail of a rake crane rotary trolley, belonging to the field of crane rail construction technology. Background Technology

[0002] Our steelmaking plant and rail beam plant have 12 scraper cranes, which require a major overhaul on average every 3 years. Due to busy production, the scraper cranes undergo frequent inspections and maintenance. The replacement of the upper trolley's circular track is generally done in two ways: either during scheduled maintenance or during a major overhaul. The circular track is typically manufactured using a pressed and bent process, with a diameter of 6100mm, and consists of two semicircles. After pressing, during storage, the two semicircles expand outwards under stress, typically by 5mm to 10mm, causing installation difficulties and requiring on-site correction. The original method involved hoisting the circular track to the installation location for arc verification, and then correcting it on the upper trolley or by hoisting it to the ground. This traditional method involved high-altitude work on the trolley, and transporting spare parts to the ground was difficult due to the curved track's hoisting, making safety difficult to control. Furthermore, the correction process was time-consuming, difficult, and required significant manpower and resources. Meanwhile, the calibration time requires one shift. Since the steel mill and rail beam plant mainly use the cranes to ensure the production of 100-meter rails for the rail beams, the production pace is tight and the construction period requirements are high. Traditional maintenance methods cannot meet the production requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing circular track arc verification operation is difficult to control and takes a long time to correct.

The fixing component includes a card seat and an adjusting component. The card seat is set at both ends of the main tie rod. The card seat is provided with an opening. The opening direction is perpendicular to the axis of the main tie rod. The adjusting component is inserted into the side wall of the card seat groove. The insertion length of the adjusting component is adjustable, and the adjusting component can be fixed with the card seat.

[0007] The card holder in the above device has an inverted U-shaped structure.

[0008] Furthermore, the card holder in the above-mentioned device is welded from steel plates.

[0009] Furthermore, the above-mentioned device also includes an auxiliary tie rod, one end of which can be connected to the middle of the main tie rod, and the other end is provided with a fixing component.

It includes a main tie rod 4 and a fixing member 2. The fixing member 2 includes a retaining seat 21 and an adjusting member. The retaining seat 21 is located at both ends of the main tie rod 4 and has an opening perpendicular to the axis of the main tie rod 4. The adjusting member passes through the side wall of the groove in the retaining seat 21, and its insertion length is adjustable. The adjusting member can be fixed to the retaining seat 21. Those skilled in the art will understand that this device can not only correct deformed circular tracks 1, but also be installed on existing spare circular tracks 1 to prevent deformation of the spare parts during storage. This device mainly includes a main pull rod 4 and a fixing member 2. The fixing member 2 is mainly used to be clamped on the semi-circular track that constitutes the ring track 1. The fixing member 2 includes a clamping seat 21 and an adjusting member. The clamping seat 21 is set at both ends of the main pull rod 4 to keep the main pull rod 4 connected to the outer wall of the clamping seat 21. An opening is provided on the clamping seat 21 so that the clamping seat 21 is fastened to the opening end of the track through the opening. Preferably, the opening direction is perpendicular to the axis of the main pull rod 4. At the same time, the adjusting member is inserted into the groove side wall of the clamping seat 21 so that the insertion end of the adjusting member is inserted into the groove on both sides of the track. The insertion length of the adjusting member is adjustable and the adjusting member can be fixed to the clamping seat 21. Since the insertion end of the adjusting member directly abuts against the bottom surface of the track groove, the main pull rod 4 can be tightened by adjusting the insertion length of the adjusting member, so as to adjust the track opening distance, that is, the radius. At the same time, locking the adjusting member also fixes the adjusting member to the clamping seat 21. The track radius can be corrected by fixing the insertion length of the adjusting member.

[0021] Preferably, the adjusting component in the above-described device is a screw structure, and a threaded hole is provided on the side wall of the opening of the card holder 21, and the adjusting component is threadedly connected to the card holder 21. Those skilled in the art will understand that, in order to facilitate control of the insertion length of the adjusting component, this device preferably uses a screw structure for the adjusting component, and a threaded hole is provided on the side wall of the opening of the card holder 21, so that the adjusting component is threadedly connected to the card holder 21. This structure allows for the adjustment and fixing of the insertion length of the adjusting key by actually turning the adjusting component under the action of the thread preload, making actual operation more convenient.

[0022] Preferably, the adjusting components in the above-mentioned device include an inner adjusting screw 23 and an outer adjusting screw 22. Threaded holes are provided on both sides of the opening of the card holder 21.

Those skilled in the art will understand that, for ease of adjustment, this device preferably includes an inner adjusting screw 23 and an outer adjusting screw 22. To facilitate the threaded connection between the inner adjusting screw 23 and the outer adjusting screw 22 and the card holder 21, threaded holes are provided on both sides of the opening of the card holder 21. The inner adjusting screw 23 and the outer adjusting screw 22 are respectively inserted through the two sides of the opening and threadedly connected to the card holder 21. This structural arrangement allows the deformable track to achieve the desired arc shape to meet installation requirements simply by turning the inner adjusting screw 23 and the outer adjusting screw 22.

[0023] Preferably, the card holder 21 in the above-described device has an inverted U-shaped structure. Those skilled in the art will understand that, in order to ensure that the card holder 21 is always secured to the track during alignment and anti-deformation operations, the card holder 21 is preferably inverted U-shaped, so that the track is placed within the U-shaped opening of the card holder 21.

[0024] Preferably, the card holder 21 in the above-described device is welded from steel plates. Those skilled in the art will understand that, in order to reduce costs and facilitate manufacturing, the card holder 21 is preferably welded from steel plates, specifically by welding three steel plates to form an inverted U-shaped structure.

[0026] Preferably, the length direction of the adjusting member in the above-described device is perpendicular to the opening direction of the card holder 21. Those skilled in the art will understand that, in order to ensure that the force of the adjusting member is fully applied to the track, it is preferable that the length direction of the adjusting member is perpendicular to the opening direction of the card holder 21 to reduce losses.

[0027] Preferably, the two side walls of the opening of the card holder 21 in the above-described device are arranged in parallel. Those skilled in the art will understand that, in order to ensure the effective function of the main tie rod 4 and to ensure that the force acting on the end of the track opening is as diametrically as possible, the two side walls of the opening of the card holder 21 are preferably arranged in parallel.
