Abstract
The invention relates to a lower wheel compressing device of a hoister, comprising a hoisting mechanism and the lower wheel. The invention is characterized in that: in the hoisting mechanism, a cradle is arranged at the upper part of a case body plate, a bearing seat plate is arranged at the lower part of the case body plate, the cradle uses the first nut to be screw connected to the upper end of an adjusting screw rod, the lower end of the screw rod is connected with the bearing seat plate, a spring gland is arranged at the middle part of the adjusting screw rod, and a spring is arranged on the section of the adjusting screw rod between the cradle and the spring gland. The invention realizes high degree adjustment of the lower wheel by transmission of the screw rod, namely the adjustment of center-to-center spacing between an upper wheel and the lower wheel, thus achieving the effects of tensioning and relaxing of a transmission body with obvious labor-saving effect.
Description
Technical field
The present invention relates to a kind of gig lower whorl pinch device, belong to mechanical field.
Background technology
The vertical-type bucket elevator is with the equipment of material from the low level vertical-lift to certain altitude.It carries the tensioning of body and absent-mindedness generally is to realize by the height of regulating lower whorl (flower wheel).
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of labor-saving effect tangible gig lower whorl pinch device is provided.
According to technical scheme provided by the invention, described gig lower whorl pinch device, comprise lifting mechanism and lower whorl, it is characterized in that: in described lifting mechanism, suspension bracket is set, bearing plate is set in the bottom of box plate on the top of box plate, suspension bracket utilizes the be spirally connected upper end of adjusting screw(rod) of first nut, the lower end of adjusting screw(rod) is connected with bearing plate, at the middle part of adjusting screw(rod) spring capping is set, and the adjusting screw(rod) between suspension bracket and the spring capping is provided with spring.
Be provided for second nut of retainer spring gland on the screw rod below described spring capping.Described bearing plate is provided with the Long Circle groove, and described lower whorl is arranged at the rear side of box plate, and the axle of lower whorl is slidingly connected in the Long Circle groove.
The present invention promptly goes up the width between centers of wheel and lower whorl and regulates by the height adjustment of screw mandrel transmission realization lower whorl, reaches the tensioning and absent-mindedness effect of carrying body, and the labor-saving effect is obvious.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
Shown in Fig. 1～2: pinch device comprises bearing plate 1, adjusting screw(rod) 2, spring capping 3, spring 4, first nut 5, lower whorl 6, box plate 7, suspension bracket 8, second nut 9 etc.
The present invention includes lifting mechanism and lower whorl 6, in described lifting mechanism, on the top of box plate 7 suspension bracket 8 is set, in the bottom of box plate 7 bearing plate 1 is set, suspension bracket 8 utilizes the be spirally connected upper end of adjusting screw(rod) 2 of first nut 5, the lower end of adjusting screw(rod) 2 is connected with bearing plate 1, at the middle part of adjusting screw(rod) 2 spring capping 3 is set, and the adjusting screw(rod) 2 between suspension bracket 8 and the spring capping 3 is provided with spring 4.Be provided for second nut 9 of retainer spring gland 3 on the screw rod 2 below described spring capping 3.Described bearing plate 1 is provided with Long Circle groove 10, and described lower whorl 6 is arranged at the rear side of box plate 7, and the axle of lower whorl 6 is slidingly connected in the Long Circle groove 10.
Principle of work of the present invention: rotate second nut 9, guarantee that spring 4 is in free state, during initial adjustment, rotate first nut, 5 controllable adjustable screw rods 2, the moving up and down of adjusting screw(rod) 2 can drive lower whorl 6 and realize moving up and down; Generally when installing or keep in repair, when being in relaxed state, first nut 5 can realize that lower whorl 6 is in running order; Promptly be totally released when not stressing when first nut 5, by rotating second nut 9, holddown spring 4 can make lower whorl 6 highly reduce.
