Description

Technical Field

[0001] The utility model relates to the technical field of hoisting, in particular to an auxiliary tool for safe hoisting of a straightening machine roller system. Background Art

[0002] The medium and thick plate straightening machine is used to straighten the rolled steel plates, improve the straightness of the steel plates, and make the products meet the delivery requirements. The straightening machine roller system is the core component of the straightening machine, which is mainly composed of a frame, a transmission device, a roller box, and an adjustment mechanism. The working temperature of the hot zone straightening machine is between 450℃ and 950℃. With the increase in production, the straightening machine roller system needs to be replaced periodically or replaced in case of abnormal failure; unplanned replacement of the roller system will generally seriously affect the production rhythm. Due to the limitations of site space and the hoisting position of the roller system, each time the roller system is replaced, the upper roller box on the straightening machine needs to be removed before hoisting can be carried out; and removing the upper roller box on the straightening machine not only poses a safety hazard, but also increases the roller changing time. When removing the upper roller box, such as Figure 1 As shown, a steel wire rope is used to directly lift the locking step 100. However, due to the sharp right-angled edges of the upper roller box 101 locking step 100, there is a risk that the shear force during the lifting process will cut the lifting rope. Therefore, there is an urgent need for a tool that can assist in the safe lifting of the roller system, while reducing unplanned maintenance time and making the lifting operation safer and more efficient. Utility Model Content

[0003] The utility model aims to provide an auxiliary tool for safely lifting the roller system of a straightening machine, which can solve the problems of low working efficiency and potential safety hazards in the prior art when replacing the roller system.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: this auxiliary tool for the safe lifting of the straightening machine roller system includes a square body, the cross-section of the bottom end of the square body is arc-shaped, and a "V"-shaped groove is opened in the middle of the bottom end. The "V"-shaped groove opens downward, and the two sides of the "V"-shaped groove extend to the two sides of the top of the square body. A door-shaped frame adapted to the size of the locking step is provided on the top of the square body.

[0005] In the technical solution of the auxiliary tool for safe lifting of the straightening machine roller system, a more specific technical solution can also be: the square body is a rectangular parallelepiped, and the setting direction of the "V"-shaped groove is perpendicular to the length direction of the square body.

[0006] In some possible embodiments, the top surface of the square body is flat, the door-shaped frame is arranged at the front end of the top surface of the square body, the top plate of the door-shaped frame extends backward, and the two side edges of the top plate aligned with the "V"-shaped groove are provided with grooves corresponding to the "V"-shaped groove.

[0007] In some possible implementation schemes, the portal frame is welded to the square body.

[0008] In some possible implementation schemes, the square body is formed by turning round steel.

[0009] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0010] When in use, the auxiliary tool is put on the locking step of the upper roller box, and the wire rope is hung in the "V" groove to ensure that the wire rope is not easy to fall off, so that the lifting operation can be carried out in a safe state; the locking step is put into the door-type frame, and the door-type frame structure fits the locking step to ensure that the tool will not be skewed during lifting, ensuring safety and reliability during lifting, improving the work efficiency of replacing the roller system, reducing the labor intensity of the operator, and reducing the chance of safety accidents.

[0016] In order to make the above-mentioned purposes, features and advantages of the present invention easier to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to fully understand the present invention, but the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] In the description of the present invention, it should be understood that the terms "middle", "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", "radial", "circumferential", etc., indicating the orientation or position relationship, are the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0018] like Figure 2 and Figure 3 The straightening machine roller shown is an auxiliary tool for safe lifting, comprising a square body 1, the bottom cross-section of the square body is arc-shaped, and a "V"-shaped groove 2 is opened in the middle of the bottom end. The "V"-shaped groove opens downward, and both sides of the "V"-shaped groove extend to both sides of the top of the square body 1. A door-shaped frame 3 that is adapted to the size of the locking step 100 is provided on the top of the square body 1. The size of the door-shaped frame 3 is adapted to the locking step 100, so that the door-shaped frame 3 can fit the locking step, ensuring that the auxiliary tool will not be skewed during lifting, and ensuring safety and reliability during lifting; the square body 1 is a rectangular parallelepiped, and the direction in which the "V"-shaped groove 2 is set is perpendicular to the length direction of the square body, and when lifting, When lifting, ensure that the steel wire ropes 4 on both sides are parallel to the two side edges of the upper roller box to ensure safety and reliability during lifting; the top surface of the square body 1 is flat, and the door-shaped frame 3 is arranged at the front end of the top surface of the square body 1, and the top plate 3-1 of the door-shaped frame 3 extends backward. The two side edges of the top plate are aligned with the "V"-shaped groove 2 and are provided with grooves 3-2 corresponding to the "V"-shaped groove. When the steel wire rope is lifted, it is placed in the "V"-shaped groove 2 and passes through the groove 3-2, which ensures that the steel wire rope is stable and does not get stuck, and also avoids the hidden danger of the shear force cutting the lifting rope during the lifting process; the square body 1 is made of round steel by turning, and the door-shaped frame is welded to the square body by welding.

[0019] During use, the auxiliary tool is placed on the locking step 100, which passes through the entrance and exit of the door frame. The door frame 3 fits the locking step, and the wire rope 4 is buckled into the "V"-shaped groove 2. During lifting, the wire rope 4 passes through the groove 3-2 simultaneously. The "V"-shaped groove 2 and groove 3-2 can limit the cross-position of the wire rope and avoid the risk of shear force severing the lifting rope during the lifting process. This example is actually used on the plate line hot straightening machine at Liuzhou Iron and Steel's First Rolling Mill. After use, the efficiency of roller replacement is improved, and the lifting operation is also more convenient, achieving the effect required by the design modification.
