Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling line steel coil transportation, in particular to a coiling fast chain guide rail device. Background Art

[0002] In the existing hot rolling line coiling unit, the fast chain carries an average single steel coil weighing 23.5 tons each time it runs. An average of more than 500 coils are rolled every day, and the chain runs more than 500 times. The original design of the height and width of the edges at both ends of the guide rail on the fast chain are very narrow, and the material is Q235, which has low strength and low wear resistance. When the edge of the upper guide rail is worn more than 5mm, the chain will deviate during operation, which not only poses a risk of derailment, but also poses a safety hazard. After being put into use, the fast chain will often run unstably due to the wear of the upper guide rail. In order to curb accidents, blocks were welded on the edge of the guide rail to maintain production. However, not only was the effect not good, but the blocks were quickly worn out or even squeezed out. There was an accident in which the chain with a steel coil derailed, which caused the rolling line to stop production for more than 3 hours.

[0003] In addition, the design width of the bottom surface of the quick chain upper rail is smaller than the actual width of the rail bracket, and the remaining size is not supported. The friction and impact on the edge of the rail when the chain is running at full load are not considered. Compared with the actual working conditions of the chain and the load it carries during operation, the maximum is about 28T. After actual use in recent years, it is found that the existing upper rail edge cannot meet the on-site working conditions at all, which leads to a short life of the upper rail, thereby increasing maintenance costs.

[0004] The upper guide rails support the movement of the fast chain. Each guide rail is nearly 4 meters long, with a total of 22 rails on both sides, with a total weight of 5034KG. According to the original design, the 22 guide rails need to be replaced as a whole every six months, and they need to wait for the annual maintenance to be implemented. If several guide rails are damaged during the six-month period, they can only be temporarily welded with blocking blocks to maintain production. Moreover, this operation is an unconventional operation with high risk and low efficiency. Even for the annual maintenance operation, since the 22 upper guide rails are installed on the chain bracket according to the drawings, when replacing the upper guide rails, it is necessary to first remove the upper chain. Every year, the annual maintenance and chain removal takes a long time, and then the sludge is cleaned; then the 22 upper guide rails are removed. Since the upper guide rails are fastened to the bracket with M16×40 hexagon socket bolts, the bolts are rusted and the threads are damaged, making them difficult to remove. It is even more time-consuming and laborious to reinstall the new upper guide rails, and each piece needs to be leveled and aligned. The operation is difficult, the construction time is long, and the efficiency is low, affecting the maintenance period of the entire hot rolling line. Summary of the invention

[0005] The utility model provides a winding fast chain guide rail device, which uses a stopper separated from the guide rail to increase wear resistance, extend the service life of the guide rail, save equipment spare parts costs, and improve maintenance efficiency.

[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0024] See Figure 1 , is a schematic diagram of the structure of the utility model. The utility model is a winding fast chain guide rail device, comprising a guide rail body 1 and a stopper 2, wherein the stopper 2 is fastened to both ends of the guide rail body 1 by fasteners; Figure 3 The block 2 is made of 45# steel and includes a transverse mounting body 201 and a vertical overlapping body 202. The vertical overlapping body 202 is 20 mm wide and 20 mm high. Fastener mounting holes 5 are provided on the transverse mounting body 201 and the guide rail body 1. The transverse mounting body 201 and the vertical overlapping body 202 are strip structures of the same length.

[0025] See Figure 2The guide rail body 1 is provided with a stop platform 6, a guide rail base 4 and a guide rail boss 3, the stop platform 6 is arranged at both ends of the guide rail base 4, the guide rail boss 3 is arranged on the inner side of the stop platform 6 and connected to the stop platform 6, the transverse mounting body 201 of the stop block 2 is arranged on the stop platform 6, and the vertical lap body 202 is in contact with the inner side of the stop platform 6, the fastener mounting holes 5 on the guide rail body 1 are evenly arranged on the center line of the stop platform 6, the guide rail boss 3 and the guide base 4 of the guide rail body 1, and the guide rail is fixed by the fastener mounting holes 5 of the guide rail boss 3 and the guide base 4, the position of the fastener mounting hole 5 on the stop platform 6 of the guide rail body 1 corresponds to the position of the fastener mounting hole 5 on the transverse mounting body 201, and the diameter is the same, the transverse mounting body 201 is fastened to the stop platform 6 by M16×35 bolts, and the width of the guide rail boss 3 is 4mm larger than the width of the outer ring of the quick chain bearing sitting on the guide rail boss 3.

[0026] Working principle: Two fast chains are arranged in parallel at both ends of the guide rail body 1, and the bearings supporting the fast chains are seated on the guide rail bosses 3 on both sides of the guide rail body 1. The fast chains are driven by the motor to transport the steel coils forward, and the positions of the stoppers 2 integrated with the guide rails at both ends of the guide rail body 1 are designed from the original design of 10mm high × 10mm wide to a 20mm high × 20mm wide strip structure. The strength and wear resistance of this strip structure guide rail are much greater than those of the Q235 material guide rail. The edge of 10mm wide and 10mm high is almost worn away by about 7mm in less than half a year. The present invention replaces the guide rail with 45# steel, and 45# steel is not damaged after heat treatment. The tube is superior to Q235 in both strength and wear resistance. During actual use, the guide rail and block 2 have not been replaced for two years, and the maximum wear does not exceed 5mm, which extends the wear resistance time of block 2 and also ensures the stability of the chain running in the upper guide rail. From the perspective of maintenance, as long as the wear of block 2 exceeds the standard wear range, it can be arranged for replacement during routine inspection. In actual use, the contact area between block 2 and the outer ring of the chain bearing is increased, so that the chain can run smoothly in the upper guide rail. Each replacement only requires replacement of block 2, and there is no need to replace the entire guide rail, which greatly saves the cost of spare parts and labor maintenance costs.

[0027] The stop block 2 and the guide rail body 1 are designed as a separate structure, and considering that the bolt may break when subjected to stress, a stop platform 6 is designed. The M16×35 bolt is used to assemble with the stop platform 6 of the guide rail, thereby ensuring that the stop block 2 is in stable contact with the guide rail body 1 without causing relative displacement. At the same time, the stop platform 6 plays a positioning and force-bearing role, so that the bolt is only subjected to tension but not shear force, thereby ensuring that the stop block 2 is firm and reliable. When the block 2 wears in the direction of the bearing end face beyond the standard range after the chain has been running for a period of time, it is only necessary to arrange to replace the left and right block 2, and the operation can be performed during routine inspection or daily repair, so that the guide rail function can be restored as soon as possible. This operation is of low difficulty, and relatively few people are required to operate it. In addition, the spare parts can be directly installed, which saves the time for installation and alignment, improves the operation efficiency, thereby improving the stability of the chain operation and accelerating the production rhythm.

[0028] The above embodiments are implemented based on the technical solution of the utility model, and detailed implementation methods and specific operation processes are given, but the protection scope of the utility model is not limited to the above embodiments. The methods used in the above embodiments are conventional methods unless otherwise specified.
