Description
Technical field
The utility model relates to a kind of tensioner that belt is carried swabbing pig tension force that is used for regulating, especially a kind of various band conveyors, as the tensioner that the used band conveyor of industries such as colliery, power plant, harbour, cement mill, grain depot uses, specifically a kind of screw rod is regulated rotary tensioner.
Background technology
As everyone knows, existing band conveyor field mostly adopts swabbing pig that conveyer belt is carried out cleaning, is used for cleaning the material that remains on the conveyer belt, keeps the normal operation of belt.Because swabbing pig need contact with belt when cleaning, the size of the tension force between swabbing pig and the belt not only can have influence on the cleanliness level of belt, also has influence on the belt maintenance.The tension force of swabbing pig and belt is too little, and cleaning is just totally not thorough, and cleanliness level is lower, but is not easy to damage conveyer belt; The tension force of swabbing pig and belt is too big, though cleanliness level improves, beat type or vibrations appear in swabbing pig easily in the use, easily cause the damage of belt.
Also do not have at present can the automatically regulating swabbing pig and belt between the device of tension force, swabbing pig mixes up the relative position of swabbing pig and belt when mounted, belt is just relative definite with the tension force between the swabbing pig, can not automatically regulating in the use, as abnormal condition, damage belt easily.
The existence of above-mentioned situation has limited swabbing pig and has played a role well, because swabbing pig lacks from conditioning function, is easy to damage blade when running into obstacle in the use, and after the swabbing pig damage, maintenance maintenance is also not too convenient.
Summary of the invention
The purpose of this utility model be can not automatic compensation during at the work of existing belt cleaner tensile force between itself and belt; thereby easily cause problem to belt damage; design a kind of can swabbing pig and belt conveyor between tension force, sweeper blade and conveyer belt are all played the screw rod of corresponding protection effect and regulate rotary tensioner.
The technical solution of the utility model is:
A kind of screw rod is regulated rotary tensioner, comprise erecting frame 8, pressing plate 4, fixed cover 10 and swivel mount 12, pressing plate 4 links to each other with erecting frame 8, fixed cover 10 and swivel mount 12 all are arranged in the installing space that is formed by erecting frame 8 and pressing plate 4, an end that it is characterized in that fixed cover 10 stretches out outside the erecting frame 8, the swabbing pig mounting pipe is by bolt 7, nut 6 is fixed in the fixed cover 10, the other end that fixed cover 10 is arranged in erecting frame 8 is installed on the end of middle elastic component 11, the other end of middle elastic component 11 is installed in the swivel mount 12, swivel mount 12 is installed in the erecting frame 8 by the screw rod 13 that passes on its engaging lug, cylindrical so nut 5 is installed on screw rod 13, and the cylindrical surface of cylindrical so nut 5 contacts rotationally with the earhole that is connected of swivel mount 12.
Fixed cover 10 is installed on the erecting frame 8 by lining 9, and the boss limit of lining 9 is arranged in erecting frame 8, and its cylinder partly stretches out outside the erecting frame 8.
The beneficial effects of the utility model:
It is a development of technology that the utility model does not have from conditioning function for swabbing pig under the prior art situation substantially; the tensioner that is provided with automatically regulating function; can realize the automatically regulating of tension force between swabbing pig and belt conveyor, sweeper blade and conveyer belt are all played good protective effect.Make the pressure that remains certain limit in the swabbing pig ground cleaning course, and can moment when running into obstacle takeoff and have " autospasy " function.
The utility model has made full use of neutral elastic component (being generally elastomeric material makes) and has had the characteristic of twisting resistance, the torsion that is subjected in use for swabbing pig has certain regulatory function, thereby can effectively avoid the damage of sweeper blade, and make cleaning effect better.
The utility model runs into foreign matter at cleaning course, as branch, rice bar, belt dung and scared belt position, can make swabbing pig moment hightail belt, and can reset immediately, realizes automatic protection functions.
The utility model also has simple in structure, makes the advantage that has easy for installation.
Description of drawings
Fig. 1 is a three-dimensional decomposition texture scheme drawing of the present utility model
Fig. 2 is the mounting structure scheme drawing of Fig. 1.
Fig. 3 is the plan structure scheme drawing of Fig. 2.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1～3.
Among the figure: 1 is bolt (M6 * 15, gauge member); 2 is spring shim (Φ 6); 3 is pad (Φ 6); 4 is pressing plate; 5 is the cylindrical so nut; 6 is nut (M12); 7 is bolt (M12 * 40); 8 is erecting frame; 9 is lining; 10 is fixed cover; 11 is elastic component; 12 is swivel mount; 13 is screw rod; 14 is jump ring.
A kind of screw rod is regulated rotary tensioner, comprise erecting frame 8, pressing plate 4, fixed cover 10 and swivel mount 12, pressing plate 4 is by bolt 1, spring shim 2 and pad 3 link to each other with erecting frame 8, fixed cover 10 and swivel mount 12 all are arranged in the installing space that is formed by erecting frame 8 and pressing plate 4, fixed cover 10 is sleeved in the lining 9, the boss limit of lining 9 is arranged in erecting frame 8, the end that its cylinder partly stretches out erecting frame 8 external fixation cover 10 stretches out outside the erecting frame 8, the swabbing pig mounting pipe is by bolt 7, nut 6 is fixed in the fixed cover 10, the other end that fixed cover 10 is arranged in erecting frame 8 is installed on the end of middle elastic component 11, the other end of middle elastic component 11 is installed in the swivel mount 12, swivel mount 12 is installed in the erecting frame 8 by the screw rod 13 that passes on its engaging lug, as Fig. 1, shown in 3, cylindrical so nut 5 (as Fig. 2) is installed on screw rod 13, and the cylindrical surface of cylindrical so nut 5 contacts rotationally with the earhole that is connected of swivel mount 12.
