Abstract
A chain tensioning device for a chain elevator of a bar production line is characterized in that lower bases mutually symmetrical are arranged on the front side and the rear side of a base plate, each lower base comprises two lower vertical plates which are arranged at a certain interval, the upper ends of the two vertical plates are connected through a third connecting plate and are provided with two upper vertical plates, the upper ends and the lower ends of the two upper vertical plates are respectively connected through a first connecting plate and a second connecting plate, two slide rails are arranged on the opposite inner sides of the two upper vertical plates, a slide seat is arranged between the slide rails and provided with a throughout hole and a vertical fixed hole, a lead screw is inserted into the fixed hole and provided with an adjusting nut arranged below the slide seat, the uppermost connecting plate is provided with a threaded hole, a bolt is inserted into the fixed hole, and the bottom end of the bolt contacts with the slide seat. The height of a tensioning gear is adjusted by adjusting the height of the slide seat, tightness degree of a chain can be adjusted, the chain can be tensioned, tension effect is good and falling of the chain can be avoided.
Description
Technical field:
The utility model belongs to tightening device, is specifically related to the chain stretching device of production line of bar caterpillar elevater.
Background technology:
The tensioning frame of the caterpillar elevater of steel rolling mill's production line of bar is bad to the tension effects of chain, often falls chain, and damages easily, and maintenance is large, and maintenance time is long, and the maintenance load is large.Because the tension effects of chain is bad, and steel billet is dropped, the steel billet that drops often smashes the roller of below, coupler, motor, reductor etc., and its loss is serious.
Summary of the invention:
The purpose of this utility model provides a kind of chain stretching device of production line of bar caterpillar elevater, and its reasonable in design, tension effects are good, can avoid chain releasing, and that guarantees to produce normally carries out.
The purpose of this utility model is achieved in the following ways: the chain stretching device of this production line of bar caterpillar elevater, the technical scheme that adopts is: the both sides, front and back of base plate are provided with symmetrical lower bottom base, described lower bottom base by two each other lower riser at regular intervals consist of, the upper end of two lower risers links to each other by the 3rd connecting panel, the upper end of two lower risers is equipped with two upper vertical plates, the top and bottom of two upper vertical plates link to each other with the second connecting panel by the first connecting panel respectively, the second connecting panel and the 3rd connecting panel are bolted fixing, two relative inboards of upper vertical plate are provided with slide rail, be provided with slide between two slide rails, axis hole before and after slide is provided with and runs through, slide is provided with vertical fixed orifice, be inserted with leading screw in the fixed orifice, the lower end of leading screw is run through the second connecting panel and the 3rd connecting panel and is fixed with both by nut, the place, below that is in slide on the leading screw is provided with setting nut, the place, top that is in slide on the first connecting panel is provided with tapped bore, penetrated bolt in the tapped bore, the bottom of bolt contacts with slide.
The beneficial effects of the utility model are: the chain stretching device of this production line of bar caterpillar elevater, regulate the height of Tension gear by the height of regulating slide, thereby the elasticity of adjusting chain, chain is carried out tensioning, its reasonable in design, tension effects are good, can avoid chain releasing, that guarantees to produce normally carries out.
Description of drawings:
Fig. 1 is front view of the present utility model.
Fig. 2 is that side of the present utility model is attempted.
The specific embodiment:
See figures.1.and.2, the chain stretching device of this production line of bar caterpillar elevater, the both sides, front and back of base plate 1 are provided with symmetrical lower bottom base, described lower bottom base by two each other lower riser 2 at regular intervals consist of, the upper end of two lower risers 2 links to each other by the 3rd connecting panel 11, the upper end of two lower risers 2 is equipped with two upper vertical plates 3, the top and bottom of two upper vertical plates 3 link to each other with the second connecting panel 10 by the first connecting panel 9 respectively, the second connecting panel 10 and the 3rd connecting panel 11 are bolted fixing, two upper vertical plate 3 relative inboards are provided with slide rail 12, be provided with slide 4 between two slide rails 12, axis hole 5 before and after slide 4 is provided with and runs through, slide 4 is provided with vertical fixed orifice 13, be inserted with leading screw 6 in the fixed orifice 13, the lower end of leading screw 6 is run through the second connecting panel 10 and the 3rd connecting panel 11 and is fixed with both by nut, the place, below that is in slide 4 on the leading screw 6 is provided with setting nut 8, the place, top that is in slide 4 on the first connecting panel 9 is provided with tapped bore, penetrated bolt 7 in the tapped bore, the bottom of bolt 7 contacts with slide 4.
This specific embodiment in use, be placed between two slides 4 being located at the Tension gear that is used for the adjusting chain degree of tension on the chain, the rotating shaft insertion of Tension gear is fixed in the axis hole 5, so just can change by the height that changes slide 4 height of Tension gear, thus the elasticity of adjusting chain.When wanting tension chain, unscrew setting nut 8 and nut is moved down, then downward turn bolt 7 is in order to promote slide 4 downwards, and then spur Tension gear downwards, thereby realize the tensioning of chain, screw setting nut 8 after putting in place and hold out against slide 4 to fix slide 4 with bolt 7 simultaneously when slide 4 moves down, prevent that it from moving up and down and affect tension effects.
