Abstract
The utility model provides a manual laborsaving chain tightener, includes the shell, changes piece, sprocket, be equipped with the gear box in the shell, the input shaft of gear box stretch out the casing of gear box outer and stretch out the end with the outside commentaries on classics piece fixed connection of shell, the output shaft of gear box stretch out gear case housing outer and stretch out the end with the outside sprocket fixed connection of shell. The utility model discloses simple structure, reasonable in design through gear drive, has improved chain tensioner's transmission effect, finally drives sprocket turns through the output shaft, makes tight chain efficiency improve to reach laborsaving mesh.
Description
Technical field
The utility model belongs to a kind of mining equiment accessory, particularly relates to a kind of saving hand chain tensioner sheet.
Background technology
Present many collieries are all use slat conveyer, often need the chain link lengthening or shorten slat conveyer, and during manual operation, at headstock both sides bolt jail chain, electrical motor makes it reverse, and reaches the object of dismounting chain.But, easily cause device damage by the mode of crawl motor, and be more dangerous operation, often occur chain link also strength cause workman to point extruding, severe one is broken finger.Although this operating mode, than very fast, be unallowed, belong to and operate against regulations in the operating instruction in colliery.Current chain tensioner sheet structure is undesirable, and this chain tensioner sheet mainly adopts connecting rod and hinge arrangement, and could be realized the object of flexible drag hook by the transmission of repeatedly power, therefore efficiency is low, and meanwhile, because the fed distance of down-hole chain is very long, very heavy, manual operation is extremely required great effort.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of saving hand chain tensioner sheet.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of saving hand chain tensioner sheet, comprise shell, switch block, sprocket wheel, gear case is provided with in described shell, the input shaft of described gear case stretches out the outer and external part of the housing of gear case and is fixedly connected with the switch block of described housing exterior, and the output shaft of described gear case stretches out the external and external part of gearhousing and is fixedly connected with the sprocket wheel of described housing exterior.
Preferably, described gear case includes housing, described gear case includes housing, the input shaft, tween drive shaft and the output shaft that are parallel to each other is provided with successively in described housing, described input shaft is fixed with driving gear, tween drive shaft is fixed with intermediate gear, described output shaft is fixed with transmission gear.
Preferably, described driving gear, intermediate gear, transmission gear are time gear.This optimal way structure is simple, can improve transmission effect very well, better realize tight chain.
Preferably, the radius of described driving gear, intermediate gear, transmission gear increases successively.This optimal way drives big gear wheel by miniature gears, realizes labour-saving object.
Preferably, described switch block is provided with pit, and described pit internal fixtion connects rocking bar.
The beneficial effects of the utility model are: structure is simple, reasonable in design, by gear transmission, improves the transmission effect of chain tension adjusting device, drive sprocket rotation, tight chain efficiency is improved, and reaches laborsaving object eventually through output shaft.

In figure: 1-rocking bar, 2-switch block, 3-input shaft, 4-sprocket wheel, 5-output shaft, 6-shell, 7-gear case, 8-driving gear, 9-tween drive shaft, 10-intermediate gear, 11-transmission gear.
Detailed description of the invention
Below introduce with reference to the accompanying drawings and an embodiment of the present utility model is described.
A kind of saving hand chain tensioner sheet, comprise shell 6, switch block 2, sprocket wheel 4, gear case 7 is provided with in described shell 6, the input shaft 3 of described gear case 7 stretches out the outer and external part of the housing of gear case 7 and is fixedly connected with the switch block 2 of described shell 6 outside, the output shaft 5 of described gear case 7 stretch out gear case 7 housing outward and external part be fixedly connected with the sprocket wheel 4 of described shell 6 outside.Described gear case 7 includes housing, the input shaft 3, tween drive shaft 10 and the output shaft 5 that are parallel to each other is provided with successively in described housing, described input shaft 3 is fixed with driving gear 8, tween drive shaft 9 is fixed with intermediate gear 10, described output shaft 5 is fixed with transmission gear 11.Described driving gear 8, intermediate gear 9, transmission gear 11 are time gear.The radius of described driving gear 8, intermediate gear 9, transmission gear 11 increases successively.Described switch block 2 is provided with pit, and described pit internal fixtion connects rocking bar 1.
During use, being rotated by rocking bar 1 drives switch block 2 that the input shaft 3 in gear case 7 is rotated, intermediate gear 9 is driven to rotate by driving gear 8 on input shaft 3, and then driven transmission gear 11 to rotate by tween drive shaft 9, movable sprocket 4 is with to rotate eventually through output shaft 5, on sprocket wheel 4, chain tightens up, and realizes tight chain.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
