Summary of the invention
For the technical problem existed in above-mentioned prior art, the invention provides a kind of idler wheel steel belt pre-tightening apparatus, by being arranged on controlling device in roller and hold down gag, realizing the adjustment to steel band elasticity and pretension.Because all controlling devices and hold down gag are all placed within roller, take up room so this compact design has greatly been saved, can the narrow workplace of meeting spatial, this design simultaneously also has adjustment, feature easy to maintenance.
For achieving the above object, the technical solution adopted in the present invention is as follows:
A kind of idler wheel steel belt pre-tightening apparatus, is included in two steel bands staggered, mutually do not interfere in space on vertical direction, and it is separate that two steel bands connect a set of function separately, do not produce controlling device and the hold down gag of interference; One of them steel band controlling device comprises locating stud, for the locating stud lock screw of locking and positioning pin and steel band attachment screw, hold down gag comprises compact heap and housing screw on compact heap under steel band, steel band; Another steel band controlling device comprises locating stud, for the locating stud lock screw of locking and positioning pin and steel band attachment screw, hold down gag comprises compact heap, holddown plate, holddown plate set screw and housing screw on compact heap under steel band, steel band; Two steel bands are connected on locating stud respectively by steel band attachment screw, and are wound around in the opposite direction, realize roller thus and rotate; Under steel band, on compact heap and steel band, compact heap remains on required compacted position respectively by the rotation of housing screw.
Under described steel band, on compact heap and steel band, compact heap compresses with inclined-plane.
Described locating stud inserts in idler wheel bottom positioning pin hole.
Described locating stud has a word adjustment tank.
Described locating stud lock screw and housing screw all exposed above roller and outer fix.
Technical solution of the present invention, by rotating the locating stud that can rotate freely, realize the adjustment to the steel band elasticity be connected on locating stud, simultaneously by compact heap and compact heap on steel band under the steel band that installs wedge shape in roller additional, upper compact heap and the compression of lower compact heap transverse shifting realization to steel band; The maintenance of pre-stressed position is locked by housing screw and is realized.Locating stud lock screw is used to be locked by locating stud, to strengthen pretension reliability.Unclamp locating stud lock screw and housing screw, adjust steel band elasticity as required, last locking and positioning pin locking screw and housing screw.
Accompanying drawing explanation
Fig. 1 is roller overall structure schematic diagram of the present invention;
Fig. 2 is idler wheel steel belt structural drawing of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated: the present embodiment is implemented under premised on technical solution of the present invention, give detailed mode of execution, but protection scope of the present invention is not limited to following embodiment.
As depicted in figs. 1 and 2, steel band 1 is connected on different pins respectively by attachment screw 1 and attachment screw 1 from steel band 22, and is wound around in the opposite direction, realizes roller 3 thus and rotates.Staggering in steel band 1 and steel band 22 in the vertical direction space, does not mutually interfere.
Steel band 1 and each own a set of controlling device of steel band 22 and hold down gag, function is separate, does not produce interference.As shown in Figure 2, steel band 1 connect controlling device and pre-tightening apparatus be made up of compact heap 1 and housing screw 1 on compact heap 1, steel band under locating stud 1, steel band attachment screw 1, locating stud lock screw 1, steel band; The controlling device that steel band 22 connects and pre-tightening apparatus are made up of compact heap 2 11, holddown plate 15, holddown plate set screw 17 and housing screw 2 16 on compact heap 2 10, steel band under locating stud 2 14, steel band attachment screw 2 13, locating stud lock screw 2 12, steel band.
When steel band 1 assembles, by steel band attachment screw 1, one end of steel band 1 is connected with locating stud 1.Locating stud 1 inserts in roller 3 bottom dowel pin hole, and namely the cooperation of its micro-gap can not have an impact to positioning precision, is enough to again freely the turning round with certain surface friction drag ensureing locating stud 1.Lower compact heap 1 and upper compact heap 1 compress with inclined-plane, and remain on required compacted position by the fastening of housing screw 1.Steel band 1 is pressed in the vertical plane of roller groove by the vertical plane of lower compact heap 1.
After such assembling, rotate locating stud 1, just can adjust the elasticity of steel band 1.Then, locking housing screw 1, to be fixed on pre-stressed position by steel band 1.Finally, locating stud lock screw 1 is used to lock, locating stud 1 to strengthen pretension reliability.
When safeguarding, unclamp locating stud lock screw 1 and housing screw 1, according to said sequence adjustment steel band elasticity, last locking and positioning pin locking screw 1 and housing screw 1.Because a word adjustment tank of locating stud, locating stud lock screw 1 and housing screw 1 are all positioned at above roller and outside, therefore adjustment and maintenance is convenient, and operability is stronger.
When steel band 22 assembles, by steel band attachment screw 2 13, one end of steel band 22 is connected with locating stud 2 14.Locating stud 2 14 inserts in roller 3 bottom dowel pin hole, and namely the cooperation of its micro-gap can not have an impact to positioning precision, is enough to again freely the turning round with certain surface friction drag ensureing locating stud 2 14.Lower compact heap 2 10 and upper compact heap 2 11 compress with inclined-plane, and are subject to the constraint of the housing screw 2 16 being threaded onto holddown plate 15 tapped hole, to remain on required compacted position.Steel band 22 is pressed in the vertical plane of roller groove by the vertical plane of lower compact heap 2 10.
After such assembling, rotate locating stud 2 14, just can adjust the elasticity of steel band 22.Then, locking housing screw 2 16, to be fixed on pre-stressed position by steel band 22.Finally, locating stud lock screw 2 12 is used to lock, locating stud 2 14 to strengthen pretension reliability.
When safeguarding, unclamp locating stud lock screw 2 12 and housing screw 2 16, according to said sequence adjustment steel band elasticity, last locking and positioning pin locking screw 2 12 and housing screw 2 16.Because a word adjustment tank of locating stud, locating stud lock screw 2 12 and housing screw 2 16 are all positioned at above roller and outside, therefore adjustment and maintenance is convenient, and operability is stronger.
These are only that specific embodiments of the invention are described.The present invention is not limited to above-mentioned particular implementation, and those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect protection scope of the present invention.
