Description

Technical Field

[0001] This utility model belongs to the technical field of traction devices, and specifically relates to a strip steel pulling device. Background Technology

[0002] Strip breakage is a serious shutdown problem in galvanizing production, resulting not only in scrapped galvanized products but also significant waste of manpower and resources, and making strip movement difficult during reconnection. Especially when the breakage occurs between the zinc pot and water quenching equipment in a vertical galvanizing furnace, quickly removing the scrap strip from the equipment area, clearing the strip's path, and then pulling the broken strip end to a suitable position for welding is extremely difficult and poses certain production safety risks. When such a breakage occurs, the entire production line is forced to shut down for an extended period, severely impacting production efficiency. Therefore, it is necessary to design a device that facilitates strip pulling to reduce downtime. Summary of the Invention

[0003] This utility model provides a strip steel pulling device to solve the technical problems existing in the prior art. By adding a pulling device to the existing equipment foundation of the vertical furnace, the strip steel can be effectively pulled to move, thereby realizing the rapid resumption of production.

[0004] This utility model includes the following technical solution:

[0005] A strip steel pulling device includes a winch, a guide wheel, and a wire rope; the guide wheel is detachably mounted on the side of a zinc pot, and the winch is fixed in the middle of a vertical furnace support; the head of the wire rope is fixed to the winch, the middle of the wire rope passes sequentially through the guide wheel, a first steering roller assembly at the top of the vertical furnace support, and a second steering roller assembly at the bottom of the vertical furnace support, and the tail of the wire rope is fixed to the strip steel to be pulled; during traction, the winch winds up the wire rope and pulls the strip steel to move in the opposite direction of the production line within the vertical furnace.

[0006] Furthermore, when a spray device is provided at the outlet and inlet of the second steering roller assembly, the wire rope passes through the spray device when entering and exiting the second steering roller assembly.

[0007] Furthermore, several cooling air boxes are provided between the spraying device and the first steering roller assembly, and between the first steering roller assembly and the zinc pot, with the steel wire rope passing through the working channel of the cooling air box.

[0008] Furthermore, when the spacing between equipment within the vertical furnace support is narrow, at least two traction wheels are installed on the side of the vertical furnace support. Due to differences in the location and length of the broken strip, suitable welding positions may not be found among the existing equipment within the vertical furnace support. Therefore, pulling the strip out of the original production line makes welding operations easier.

[0009] Furthermore, the wire rope does not pass through the working channel of part of the cooling box when it passes the traction wheel.

[0010] Furthermore, a third steering roller assembly is provided between the second steering roller assembly and the outlet steering roller, located in the middle of the vertical furnace support.

[0011] Furthermore, the end of the wire rope is spot-welded to the strip to be pulled, or a hole is drilled in the strip to be pulled and the end of the rope is fixed with a lock.

[0012] The advantages and positive effects of this utility model are as follows:

[0013] 1. This utility model achieves the traction of broken strip by adding a winch, wire rope, guide wheel, traction wheel and other devices to the original equipment, thereby reducing equipment downtime; the scrap steel strip is quickly lifted out by the wire rope, the running path of the steel strip is cleared, and it is convenient to pull the two ends of the steel strip together for welding.

[0014] 2. The overall installation cost of this utility model is low, it does not conflict with the original equipment, it is highly practical, simple to operate, and saves manpower and resources. Attached Figure Description

Detailed Implementation

[0018] To further disclose the invention content, features, and effects of this utility model, the following examples are provided in conjunction with the accompanying drawings for detailed description. In the following description of the embodiments, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this patent and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this patent.

[0019] In the following description of the embodiments, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0020] Example 1: See Appendix Figure 1 A strip steel pulling device includes a winch 6, a guide wheel 5, and a wire rope 4. The guide wheel 5 is detachably mounted on the side of a zinc pot 1. The winch 6 is fixed in the middle of a vertical furnace support 3. The head of the wire rope 4 is fixed to the winch 6. The middle of the wire rope 4 passes sequentially through the guide wheel 5, a first steering roller assembly 7 at the top of the vertical furnace support 3, and a second steering roller assembly 8 at the bottom of the vertical furnace support 3. The tail of the wire rope 4 is fixed to the strip steel 2 to be pulled. The tail of the wire rope 4 is spot-welded to the strip steel 2 to be pulled, or a hole is drilled in the strip steel 2 to be pulled and the tail is fixed with a lock. During traction, the winch 6 winds up the wire rope 4 and pulls the strip steel 2 in the opposite direction of the production line within the vertical furnace.

[0021] When a spray device 10 is provided at the outlet and inlet of the second steering roller assembly 8, the wire rope 4 passes through the spray device 10 when entering and exiting the second steering roller assembly 8. Several cooling air boxes 11 are provided between the spray device 10 and the first steering roller assembly 7, and between the first steering roller assembly 7 and the zinc pot 1, and the wire rope 4 passes through the working channel of the cooling air box 11. A third steering roller assembly 9 is also provided between the second steering roller assembly 8 and the outlet steering roller 12, located in the middle of the vertical furnace support 3.

[0022] Working Principle: During the galvanizing process, strip steel 2 is prone to breakage at locations such as the zinc pot 1 and water quenching (spray device 10), which is very difficult to handle. However, the use of a winch 6 and wire rope 4 makes this process much easier. After the strip steel 2 breaks, the winch 6 transports the wire rope 4 to the breakage point, bringing the two broken joints together for welding. After use, the wire rope 4 and guide wheel 5 are retracted without affecting the production line operation.

[0023] Example 2: See Appendix Figure 2A strip steel pulling device is described, with other structures basically the same as in Embodiment 1. When the equipment spacing within the vertical furnace support 3 is narrow, two or more traction wheels 13 (two in this example) are installed on the side of the vertical furnace support 3. Due to differences in the location and length of the broken strip, suitable welding positions may not be found among the existing equipment within the vertical furnace support 3. Therefore, pulling the strip steel 2 out of the original production line makes welding operations easier. When the wire rope 4 passes through the traction wheel 13, it does not pass through the working channel of part of the cooling air box 11.

[0024] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit and scope of the claims. These modifications all fall within the protection scope of the present invention.
