Abstract
A transverse moving type tension mechanism for the chain type transmission unit is composed of machine frame, guide track connected to machine frame, tension frame movable on guide track, guide wheel module installed to said tension frame, an axle with one end connected to tension frame and another end linked with tension chain gear via bearing, and a counter weight linked with guide wheel module.
Description
Technical field
The present invention relates to technical field of conveying machinery, specifically a kind of tightening device of chain-type transmission device.
Background technology
In the prior art, gravity tensioning mechanism mostly vertically moves, and promptly realizes tensioning by tensioning frame and sprocket wheel with clump weight moving on gravity direction.The defective of this tensioning mode is the manufacturing cost height, and using has certain limitation; To requirement on height of workshop than higher, particularly under the situation that stroke of tension is bigger, on the factory building height space difficulty meet the demands; And fall by the gravity of counterweight pulling sprocket wheel fully, the alerting ability when guaranteeing that idler sprocket falls, to the requirement of assembling than higher.
Summary of the invention
The objective of the invention is to design a kind of laterally sliding tensioner, to satisfy the requirement that the rotary immersion type conveying machine system space is little, stroke of tension is big, precision is high, thereby provide a kind of use steel rope to realize turning to by assembly pulley, make the longitudinal movement of clump weight be converted into tensioning frame and idler sprocket side travel along guide rail, and utilize the characteristic of movable pulley, reduce the novel tensioning mechanism of the weight and volume of counterweight part.
According to design plan provided by the present invention, guide track is connected with frame, guide wheel assemblies is installed on the tensioning tressel, and the tensioning tressel movably frame on guide track, one end of axle links to each other with the tensioning tressel, the other end utilizes bearing to be connected with idler sprocket, and laborsaving counter weight device is connected with guide wheel assemblies.
Floating type turning rack guide track is installed on the tensioning tressel.Connect adjustable number device of long distance on frame, the other end of adjustable number device of this length distance is fixed on the tensioning tressel.On the tensioning tressel, travel switch is installed.
On frame, connect the chain trapped orbit, connect the chain movable rail at the tensioning tressel.On guide track, connect the stroke of tension cuing scale, on guide wheel assemblies, connect the stroke of tension pointer.Weight in the laborsaving counter weight device utilizes rope and guide wheel assemblies, and rope is on the pulley that is installed on the frame.
Compared with the prior art the present invention has characteristics such as simple in structure, compact, reasonable; Owing to adopt and realize tensioning along the side travel of guided way, saved height space, stroke of tension is big; Utilize the characteristic of movable pulley, reduce the weight and volume of counterweight part, reduced manufacturing cost; The tensioning activity is flexible, and is easy to use, stable performance, degree of automation height.
Description of drawings
Fig. 1 is a structural front view of the present invention.
Fig. 2 is a structure left view of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly is made up of parts such as idler sprocket 1, tensioning tressel 2, guide wheel assemblies 3, axle 4, guide track 5, laborsaving counter weight device 6, floating type turning rack guide track 7, stroke of tension cuing scale 8, stroke of tension pointer 9, travel switch assembly 10, adjustable number device 11 of long distance, chain trapped orbit 12, chain movable rail 13.
As shown in the figure: guide track 5 is connected with frame, guide wheel assemblies 3 is installed on the tensioning tressel 2, and tensioning tressel 2 movably frame on guide track 5, one end of axle 4 links to each other with tensioning tressel 2, the other end utilizes bearing to be connected with idler sprocket 1, and laborsaving counter weight device 6 is connected with guide wheel assemblies 3.Floating type turning rack guide track 7 is installed on tensioning tressel 2.
Connect adjustable number device 11 of long distance on frame, the other end of adjustable number device 11 of this length distance is fixed on the tensioning tressel 2.Travel switch 10 is installed on tensioning tressel 2.
On frame, connect chain trapped orbit 12, connect chain movable rail 13 at tensioning tressel 2.On guide track 5, connect stroke of tension cuing scale 8, on guide wheel assemblies 3, connect stroke of tension pointer 9.Weight in the laborsaving counter weight device 6 utilizes rope and guide wheel assemblies 3, and rope is on the pulley that is installed on the frame.
Principle of work of the present invention and working process: the present invention is that a kind of pulley that utilizes turns to, and rope traction drives tensioning tressel and sprocket wheel side travel and realizes slack-free equipment.Wherein laborsaving counter weight device 6 by pulley and rope traction guide wheel assemblies 3 along guide track 5 side travels, because guide wheel assemblies 3 is installed on the tensioning tressel 2, thereby idler sprocket 1 side travel that drives tensioning tressel 2 and link to each other with tensioning tressel 2 is realized tensioning thus.During tensioning, chain movable rail 13 is with tensioning tressel 2 side travels, and chain trapped orbit 12 is motionless, realizes the seamless link of chain track; Floating type turning rack guide track 7 one end positions are fixed, and an end side travel, track are done corresponding flexible, realize the transition of turning rack track.After reaching tensioning, will grow adjustable number device of distance and 11 adjust to the relevant position, in the time of in working order,, touch travel switch assembly 10, and in time send out and number report to the police if when having chain jamming and other improper situations to occur.Stroke of tension cuing scale 8 is fixed on the guide track 5, and that stroke of tension pointer 9 is done with whole tensioning tressel 2 is traversing, thus the indication stroke of tension, so that tightening device during near the maximum tension stroke, is in time adjusted chain length.
