Abstract
The utility model provides a driving sprocket overspeed device tensioner with adjustable, its includes the base, it is the cylinder, and upper end open -ended central passage is seted up to the axial, and the guide slot that link up with the central passage is seted up along the axial to the both sides face that the base is relative, a pivot wears to locate base both sides face guide slot, pivot are located radially sets up the screw on the axle body of base, an adjusting screw, from the pivot screw is worn to establish in inserting the base in the base upper end to with the pivot meshing, the pivot is rotated and is gone up and down along with adjusting screw, the tightener sprocket, set up in the one end of pivot, the driving chain guide rail is the arc, and its guide rail central authorities establish the confession the through -hole that the tightener sprocket was placed, the guide rail side is to offering the installation through -hole that supplies the pivot to wear to establish by the through -hole to with this coaxial setting in the pivot, the tightener sprocket is located the through -hole of driving chain guide rail central authorities. This practicality can in time be pressed the lax degree of driving chain and adjusted the take -up pulley, operates safe and reliable, reaches to prevent that the driving chain driving sprocket that arouses loose excessively from jumping the emergence of tooth or sprocket broken teeth trouble.
Description
Technical field
The utility model relates to drive apparatus, particularly the adjustable driving chain wheel tightening device of one.
Background technology
Sprocket transmission device is one of type of drive in material transport equipment, by drive sprocket, messenger chain, is adjusted the compositions such as tensioning hole and tensioning bolt by bottom movable sprocket and actuating device.Body delivery system equipment is all adopt single system under normal circumstances, system is run continuously, as long as there is a certain body delivery system equipment fault in whole system, capital influential system runs, directly have influence on logistical balancing, thus impact is produced, and will affect the production of coke oven and blast furnace in metallurgy industry.Meanwhile, in process of production, jump tooth or sprocket wheel broken teeth fault as there is driving chain wheel, and device location is in narrow or high-altitude, similar fault occurs, and the repair time is long, affects very large.
And existing by the device systems of chain sprocket drive, there is no this type of tightening device.In existing equipment, generally, when messenger chain needs tensioning, all by adjusting tensioning hole bottom actuating device and tensioning bolt realizes, when needing tensioning in narrow place without adjustment hole without adjustable distance or device location between two sprocket wheels, can only be saved by dismounting one or two joint messenger chains, messenger chain tension or messenger chain can be caused like this to install.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable driving chain wheel tightening device, and the relax level pressing messenger chain in time regulates tension wheel, reaches and prevents the excessively loose generation causing driving chain wheel to jump tooth or sprocket wheel broken teeth fault of messenger chain.
For achieving the above object, the technical solution of the utility model is:
A kind of adjustable driving chain wheel tightening device, it comprises, pedestal, and it is column structure, and axially offer the central aisle of upper end open, the two sides that pedestal is relative offer the guide groove through with central aisle vertically; One rotating shaft, is arranged in described pedestal two sides guide groove, and on the axle body that rotating shaft is positioned at pedestal, radial direction offers screw; One adjusting screw(rod), inserts in pedestal from described pedestal upper end, wears described rotating shaft screw, and engage with rotating shaft, and rotating shaft is rotated with adjusting screw(rod) and is elevated; Idler sprocket, is arranged at one end of described rotating shaft; Messenger chain guide rail, curved, its guideway central establishes the through hole placed for described idler sprocket, and rail-sides in the face of offering the installation through hole worn for rotating shaft by through hole, and is coaxially arranged in rotating shaft with this, and idler sprocket is positioned at the through hole of messenger chain guideway central.
The utility model device is installed on midway location below messenger chain, and idler sprocket heads on messenger chain, and pitch of holes, the hole dimension of the tooth pitch of idler sprocket, tooth and messenger chain match, in the meshing reason embedded chain hole of idler sprocket.
When messenger chain occurs lax, messenger chain is introduced by introducing guide rail, and idler sprocket regulates up mobile occlusion messenger chain through screw rod, and reach certain tension force, messenger chain is drawn by guiding out of rail again, and guide rail moves integrally along with idler sprocket.
The beneficial effects of the utility model:
The relax level that the utility model can press messenger chain in time regulates tension wheel, only need move idler sprocket by adjusting screw(rod), and safety of operation is reliable, reaches and prevents the excessively loose generation causing driving chain wheel to jump tooth or sprocket wheel broken teeth fault of messenger chain.

Detailed description of the invention
See Fig. 1 ~ Fig. 5, the adjustable driving chain wheel tightening device of one of the present utility model, it comprises, pedestal 1, it is column structure, and axially offer the central aisle 11 of upper end open, the two sides that pedestal 1 is relative offer the guide groove 12 through with central aisle 11 vertically; One rotating shaft 2, is arranged in described pedestal 1 two sides guide groove 12, and on the axle body that rotating shaft 2 is positioned at pedestal 1, radial direction offers screw 21; One adjusting screw(rod) 3, inserts in pedestal 1 from described pedestal 1 upper end, wears described rotating shaft 2 screw 21, and engage with rotating shaft 2, and rotating shaft 2 is rotated with adjusting screw(rod) 3 and is elevated; Idler sprocket 4, is arranged at one end of described rotating shaft 2; Messenger chain guide rail 5, curved, its guideway central establishes the through hole 51 placed for described idler sprocket 4, and rail-sides is in the face of offering the installation through hole worn for rotating shaft 2 by through hole, and being coaxially arranged in rotating shaft 2 with this, idler sprocket 4 is positioned at the through hole 51 of messenger chain guide rail 5 central authorities.
The utility model is installed on midway location below messenger chain 100, idler sprocket heads on messenger chain, pitch of holes, the hole dimension of the tooth pitch of idler sprocket, tooth and messenger chain match, and in the meshing reason embedded chain hole of idler sprocket, the relax level pressing messenger chain in time regulates tension wheel.When messenger chain occurs lax, messenger chain is introduced by introducing guide rail, idler sprocket regulates up mobile occlusion messenger chain through screw rod, reach certain tension force, messenger chain is drawn by guiding out of rail again, guide rail moves integrally along with idler sprocket, drops to minimum, therefore have higher value of service by the load transfer device system failure by chain sprocket drive on the impact of producing.
