Abstract

The utility model discloses a novel tensioning is led and defended to finishing mill device, taut lead when its mainly used production defend with the compensating beam reliably be connected, can play the guard action when leading to defend promoting hydraulic system trouble, the utility model discloses mainly including upper bracket 9, undersetting 6, thread bush 7, U type adjustment pad 8, pull rod 10, fixed stop 11, round pin axle 12 are constituteed, fill up through the adjustment and the thread bush fastening realizes taut lead defending. Use the utility model discloses can avoid current traditional taut calabash to appear the chain fracture easily when equipment operation and block the problem that the chain caused roll change time delay when roll change, can improve greatly and lead defend operating stability, and then reduce equipment failure rate. And meanwhile, the cost of spare parts is saved.

Description

Novel guide tensioning device of finishing mill

Technical Field

The utility model relates to a novel finishing mill is led and is defended taut device.

Background

The heavy and medium plate finishing mill guide and guard weighs 20 tons each, one is arranged in front of the finishing mill and behind the finishing mill, steel rolling follows the upper supporting roll and the upper working roll of the finishing mill, and once poor follow-up occurs, the steel plate falls down to cause serious operation equipment accidents of steel plate impact on the guide and guard. However, the problems are more in the use process, the internal structure is damaged due to the fact that water vapor on the site is large, the calabash is prone to occurring, the consumption is large, the internal structure is needed to be replaced once every month, the guide chain is broken suddenly and cannot be detected timely, the guide is directly damaged in the production process, and the guide loses the protection, and if the hydraulic system has a problem, the guide directly falls down to cause a major impact production equipment operation accident. In addition, the working rollers are replaced every day, the calabash needs to be pulled once manually, the chain of the calabash is long, and the production efficiency is seriously affected by frequent jamming.

Disclosure of Invention

An object of the utility model is to provide a novel finishing mill is led and is defended take-up device not only can reduce spare part fund and work load, can also improve production efficiency and finishing mill operation rate.

Realize a novel tensioning device is defended to finishing mill guide of above-mentioned purpose, including being fixed in the upper bracket on the finishing mill compensating beam and fixing the undersetting on leading defending, fixed two fixed stop that are setting up on the undersetting top surface, coaxial setting up the through-hole on two fixed stop, the upper bracket on vertically setting up a perforating hole, fixed stop between follow through one the round pin axle that passes in the through-hole is articulating a pull rod, upwards wearing out in the perforating hole on pull rod upper portion follow upper bracket, set up U-shaped adjustment pad and M56 thread bush on the pull rod on the upper bracket top surface from bottom to top respectively.

The utility model discloses an overall thinking is cancel original chain block, change for the pull rod, and the pinhole is taken to base both sides of installation above leading the guarding, and the pinhole is taken to the pull rod bottom, and it is fixed to wear into the round pin axle, realizes the pull rod and leads the reliable connection of guarding. The connecting point does not need to be moved generally, and the pin shaft is only needed to be removed to replace the base every 3 years. An upper support is arranged on the balance beam, a U-shaped groove is arranged in the upper support, so that the pull rod can be pushed through and pulled out, when the pull rod is pushed through to be prepared for production, a proper adjusting U-shaped pad needs to be placed in the pull rod, and then the pull rod is locked by an M56 threaded sleeve. When the roller is changed, the screw sleeve is cancelled and the pull rod is pulled out.

Through the structural form improvement of the tensioning device, the calabash needs to be tensioned in 40 minutes and replaced once per month before roller changing, the breakage of a main chain of the calabash and the blocking of a main chain and an auxiliary chain occur once every two months, and the tension rod is tensioned in 15 minutes and the thread blocking and the breakage accident of the tension rod do not occur once after roller changing at present, so that the fund and the labor load of spare parts are reduced, and the production efficiency and the operation rate of a finishing mill are improved.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic front view of a conventional structure.

Fig. 2 is a schematic view of the structure of the present invention.

Detailed Description

The utility model provides a tensioning of novel finishing mill guide, figure 1 shows for the current structure of adopting the taut guide of calabash adjustment mode, wherein on upper bracket 1 was fixed in the finishing mill compensating beam, undersetting 5 was fixed on the guide, through 2 fixed in the 1 below of upper bracket calabash 3, taut its calabash chain 4 can be through the rate of tension of undersetting 5 adjustment guide. Traditional structure has a great deal of problem, so the utility model discloses a structure shown in fig. 2, including being fixed in upper bracket 1 on the finishing mill compensating beam and fixing the undersetting 5 on leading defending, fixed two fixed stop 7 that are setting up on the 5 top surfaces of undersetting, the coaxial through-hole that is setting up on two fixed stop, upper bracket 1 on vertically setting up a perforating hole, fixed stop between follow through one the round pin axle 8 that passes in the through-hole is articulating a pull rod 6, and the through-hole on the upper bracket is upwards worn out on 6 upper portions of pull rod, and on the pull rod on the 1 top surface of upper bracket from bottom to top set up U-shaped adjustment pad 9 and M56 thread bush 10 respectively, just can conveniently lead defending through pull rod 6 is taut through rotatory thread bush 10 and increase and decrease adjustment pad 9, and adjustment and change are all very convenient.

Claims

1. The utility model provides a novel tensioning is led to finishing mill device, is including being fixed in the upper bracket on the finishing mill compensating beam and fixing the undersetting on leading defending, characterized by: the fixed two fixed stop that are setting up on the bottom suspension seat top surface, coaxial setting the through-hole on two fixed stop, the upper bracket on vertically setting up a perforating hole, the fixed stop between follow through a round pin axle that passes in the through-hole is articulating a pull rod, upwards wearing out in the perforating hole on the upper bracket of pull rod upper portion follow, set up U-shaped adjusting pad and M56 thread bush on the pull rod on the upper bracket top surface from bottom to top respectively.
