Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling equipment, in particular to a device for increasing the tension of a steel rope of a scrap steel transport trolley of a continuous annealing unit. Background Art

[0002] The scrap steel transport trolley is a device used to transport the scrap cut by the disc shear at the tail of the cold rolling mill. Its function is to transport the scrap cut by the disc shear to the scrap steel box. It moves back and forth between the bottom of the disc shear and the scrap steel box. The power is to release two 20mm diameter steel ropes from a drum for traction. When the transport trolley runs to the scrap steel tank, the hydraulic cylinder under the transport trolley lifts it up, causing the transport trolley to tip over and pour the scrap steel into the scrap tank. If you want to lift the transport trolley, the traction steel rope must have a certain amount of elongation. However, due to the certain amount of elongation of the steel rope, the steel rope has no tension. During the production process, the steel rope often cannot be normally rolled onto the drum. For example, the steel rope jumps the groove, the second layer is formed, etc., which causes the steel rope to be damaged or even broken, resulting in shutdown, which seriously affects the production efficiency of the unit. Summary of the invention

[0003] In view of the above problems, the purpose of the utility model is to provide a device for increasing the tension of the steel rope of the scrap steel transport trolley of the continuous annealing unit, which can ensure the tension of the steel rope and also ensure the elongation requirement of the steel rope when the scrap steel transport trolley is lifted up, so that the tensioning device can automatically adjust the tension of the steel rope so that the steel rope can be wound onto the drum according to the standard.

[0004] The technical solution adopted by the utility model is as follows:

[0006] Furthermore, one end of the connecting rod is fixedly connected to the swing shaft, and the other end is connected to the fixed shaft rotation pair.

[0007] Furthermore, there is a certain distance between the roller bodies of the fixed guide roller and the swing guide roller for passing the steel rope.

[0008] Furthermore, the guide roller has a diameter of 140-160 mm and a length of 1300-1400 mm.

Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0017] It should be noted that, in the description of the present invention, the terms "upper", "lower", "top", "bottom", "one side", "the other side", "left", "right", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation.

[0018] See attached Figure 1 The utility model provides a device for increasing the tension of a steel rope of a scrap steel transport trolley of a continuous annealing unit, comprising a fixed guide roller 1, a swing guide roller 2, a connecting rod 3, a fixed shaft 4 and a swing shaft 5.

[0019] Among them, the fixed guide roller 1 and the swing guide roller 2 are arranged side by side in parallel with a certain distance between the roller bodies for the steel rope 6 to pass through. In this embodiment, the diameters of the fixed guide roller 1 and the swing guide roller 2 are both 140-160mm, and the lengths are both 1300-1400mm; the fixed guide roller 1 is connected to the fixed shaft 4 via a corresponding rotation pair; the swing guide roller 2 is connected to the swing shaft 5 via a corresponding rotation pair; the front sides of the fixed shaft 4 and the swing shaft 5 are connected by a connecting rod 3, and the rear sides of the fixed shaft 4 and the swing shaft 5 are connected by a connecting rod 3, and one end of the connecting rod 3 is fixedly connected to the swing shaft 5, and the other end is connected to the rotation pair of the fixed shaft 4.

[0020] The connecting rod 3 is a rectangular rod with a length of 280-320 mm, a thickness of 8-12 mm, and a width of 60-80 mm.

[0021] The devices are used in pairs and are respectively installed on both sides of the unit winch 7, and the two ends of the fixed shaft 4 are fixed on the corresponding positions of the unit structure.

[0022] The utility model installs a group of guide rollers that can automatically swing on the steel rope 6 between the two sides of the winch 7 and the transport trolley 8, and utilizes the swing of the guide rollers to press the steel rope 6 with their own weight to keep the steel rope 6 in a taut state. When the transport trolley 8 reciprocates, one guide roller that is tensioned by the force on the steel rope 6 is lifted, and the other guide roller that is not tensioned on the steel rope 6 is pressed down to tighten the steel rope 6. When the transport trolley 8 stops running to dump materials, the transport trolley 8 is lifted up by the oil cylinder 9, and the steel rope 6 is stretched along with the transport trolley. At this time, the swinging guide roller 2 is lifted to ensure the length requirement of the steel rope 6. After the transport trolley 8 falls back, the steel rope 6 is extended, and the guide roller automatically presses the steel rope 6 to ensure that the steel rope 6 is always in a tensioned state. It automatically adjusts according to different work requirements to keep the steel rope 6 taut at all times to meet the different length requirements of the steel rope 6 when the transport trolley is running and dumping materials.
