Description

Technical Field

[0001] The invention relates to the field of lifting tools, in particular to a lifting tool for quickly processing red blanks. Background Art

[0002] Since the steel rolling heating furnace is in a continuous production process, there will be abnormal situations in production. When the walking beam is not synchronized or the stroke of the steel tapping machine is not in place, it is easy to cause the billet to not be on the claw of the steel tapping machine during steel tapping, which may cause the billet to fall. Since it is close to the heating furnace door, the temperature on site is high and personnel cannot get close. It is difficult to handle the billet after it falls, and the furnace needs to be stopped for disposal. At the same time, the billet affects the claw stroke of the steel tapping machine after it falls, causing equipment damage, secondary expansion of accidents and increasing production costs.

[0003] Therefore, it is necessary to develop new lifting tools in a targeted manner to overcome the above problems. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a lifting tool for quickly handling red billets. When the red billets fall into the furnace or under the roller, they can be handled in time, greatly reducing the processing time and preventing accidents from expanding. At the same time, it ensures that employees are safe and controlled when handling red steel.

[0005] Technical solution: The present invention is a lifting tool for quickly processing red blanks, characterized in that it includes a C-shaped slot, a lifting ring is provided on the top of the C-shaped slot, and the lifting ring is connected to an external chain; the C-shaped slot is cut from a steel plate with a thickness of 50 mm, the inside of the C-shaped slot is cut according to the cross-sectional length and width of the red blank, and a triangular groove is used at the bottom to facilitate the C-shaped slot to be inserted into the red blank.

[0006] Among them, the overall length of the C-shaped slot is 490mm, the overall width is 490mm, and the overall thickness is 50mm.

[0007] Wherein, the C-shaped slot includes an upper crossbar portion, a lower crossbar portion and a vertical bar portion; the width of the upper crossbar portion is 70 mm, and the width of the lower crossbar portion is 60 mm.

[0008] Wherein, the length of the vertical rod part is 360mm and the width is 100mm.

[0009] The distance between the lifting ring and the end of the upper crossbar of the C-shaped slot is 105 mm.

[0010] Wherein, the vertical cross-section of the hanging ring is a trapezoidal structure with a hole in the middle.

[0011] Wherein, the height of the hanging ring is 105mm.

[0012] When in use, the handling personnel control the lifting device with push-pull rods so that the C-shaped slot is inserted into the cross-section of the red billet, providing a force point for lifting the red billet. This not only solves the problem of personnel being unable to get close due to high temperature and ensures safety and control, but also can quickly handle the stuck red billet and prevent the accident from expanding again.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention is used to deal with abnormal conditions in the heating furnace. When the heating furnace equipment is abnormal and the red steel falls into the furnace or under the roller, it can greatly reduce the fault handling time, ensure the rapid lifting of the red steel, prevent the accident from expanding, and ensure that the employees are safe and controlled when handling the red steel. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of the present invention. DETAILED DESCRIPTION

[0015] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0016] The lifting tool for quickly processing red blanks of the present invention comprises a C-shaped slot, a lifting ring is provided on the top of the C-shaped slot, and the lifting ring is connected to an external chain; the C-shaped slot is cut from a steel plate with a thickness of 50 mm, the inside of the C-shaped slot is cut according to the cross-sectional length and width of the red blank, and a triangular groove is adopted at the bottom to facilitate the C-shaped slot to be inserted into the red blank.

[0017] Among them, the overall length of the C-type slot is 490mm, the overall width is 490mm, and the overall thickness is 50mm. The C-type slot includes an upper crossbar part, a lower crossbar part and a vertical bar part; the width of the upper crossbar part is 70mm, and the width of the lower crossbar part is 60mm. The length of the vertical bar part is 360mm and the width is 100mm. The distance between the lifting ring and the end of the upper crossbar part of the C-type slot is 105mm. The vertical cross-sectional shape of the lifting ring is a trapezoidal structure with a hole in the middle. The height of the lifting ring is 105mm.

[0018] When in use, the handling personnel control the lifting device with push-pull rods so that the C-shaped slot is inserted into the cross-section of the red billet, providing a force point for lifting the red billet. This not only solves the problem of personnel being unable to get close due to high temperature and ensures safety and control, but also can quickly handle the stuck red billet and prevent the accident from expanding again.

[0019] After actual application on site, timely processing can be achieved, greatly reducing the processing time, from the time required to stop the furnace for processing (about 24 hours) to about 2 hours, preventing the accident from expanding while reducing the impact on production costs, while ensuring that employees are safe and under control when handling red steel.
