Technical Field

[0001] This utility model relates to the technical field of material anti-fall devices, specifically to an anti-fall buffer device for a steel plant transfer system. Background Technology

[0002] During steelmaking operations, various ores need to be transferred between plant areas. This requires the use of numerous conveyors for transporting the ores. To prevent materials from falling during transfer, some conveyors are equipped with receiving hoppers at their feeding ends to catch materials falling from other conveyors. This effectively prevents materials from scattering during transfer between different conveyors, ensuring the safety of material transport. However, the size of the flared opening at the top of some existing receiving hoppers is fixed, while the models of the conveyors used for material transport may not be standardized. This means that the width of the conveyors may also vary, and different receiving hoppers are required for transferring ores between different models of conveyors, which brings great inconvenience to the ores transport operation.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-3As shown, this utility model embodiment provides a fall prevention buffer device for a steel plant transfer system, including a feeding channel 1, a spiral channel (not shown in the figure) is provided in the feeding channel 1, and an openable inclined collecting plate 2 is provided on each side wall of the top port of the feeding channel 1. The edges of each two adjacent collecting plates 2 are connected by an extendable connecting strip 3, and a fixing device for positioning itself is provided on the outer side of the collecting plate 2.

[0020] The fixing device includes a support plate 4 disposed on the outside of each collecting plate 2. The upper end of the support plate 4 is hinged to the collecting plate 2. The material discharge channel 1 has a fixing plate 5 placed horizontally on the outside of each of its side walls. The lower end of the support plate 4 is inclined and fixed on the fixing plate 5.

[0021] The outer side of the aggregate plate 2 is provided with a protruding mounting head 6, the top of the support plate 4 is provided with a hinge joint 7, the hinge joint 7 is hinged to the mounting head 6 through a pin 8, and the lower end of the support plate 4 is provided with a horizontally placed fixing wing 9, which is fixedly connected to the retaining plate 5.

[0022] The fixing plate 5 has several positioning holes 5a evenly distributed in the transverse direction at the position corresponding to the fixing wing 9. The fixing wing 9 is provided with fixing bolts 10, which pass through the fixing wing 9 and are threadedly connected to the positioning holes 5a.

[0023] The bottom of the fixed plate 5 is provided with a supporting rib plate 11.

[0024] The material collection plate 2 is hinged to the top of each side wall of the material discharge channel 1 via hinge 12.

[0025] Preferably, the connecting strip 3 is made of polyester fiber.

[0026] A connecting plate 13 is provided at the lower end of the feeding channel 1, and the connecting plate 13 is installed on the frame of the conveying equipment.

[0027] The working principle of this utility model is as follows: Based on the size and material discharge of the conveyor, the position of the collecting plate 2 is adjusted. First, the fixing bolts 10 are removed, allowing the support plate 4 to move freely. The collecting plate 2 is then folded outwards, causing the connecting strips 3 between the collecting plates 2 to open. After the position of the collecting plate 2 is selected, the fixing wing 9 at the lower end of the support plate 4 is aligned with the corresponding positioning holes 5a on the fixing plate 5. Then, the fixing bolts 10 are used to fix the position of the fixing wing 9, thus completing the process of adjusting the position of the collecting plate 2. The fixed and expandable collecting plate 2 can adjust the size of the entire horn opening to match the specifications of the conveyor and complete the transfer of ore. The discharge channel 1 is installed at the feeding start position of the lower conveyor. The horn opening structure formed by the collecting plate 2 at the top of the discharge channel 1 is aligned with the feeding end of the upper conveyor. The ore conveyed by the upper conveyor falls and enters the spiral channel in the discharge channel 1 along the horn opening for transport. Then it falls onto the lower conveyor for rotation. This can prevent the ore from falling during transfer.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
