Abstract
The utility model discloses an oval drum-type gasket for a fastening a screw which is used for connecting a bucket with an evaluating belt in a bucket elevator. The oval drum-type gasket is composed of a top structure, a transition connecting structure and a tilting structure, wherein the top structure, the transition connecting structure and the tilting structure are arranged continuously, the thickness of the top structure, the thickness of the transition connecting structure and the thickness of the tilting structure are the same, the transition connecting structure is arranged between the tilting structure and the top structure, the annular top structure is located on the upper most portion and in middle of the oval drum-type gasket, a round installation hole is formed in the middle of the top structure, the tilting structure which is bent towards the top in an arc-shaped mode is arranged on the edge of the lowest portion of the oval drum-type gasket, the vertical axial cross section of the transition connecting structure is conical, the horizontal radial cross section of the transition connecting structure is oval, and the radial cross section of the tilting structure is also oval. According to the oval drum-type gasket, the vertical center axis of the top structure, the vertical center axis of the transition connecting structure, the vertical center axis of the tilting structure and the vertical center axis of the installation hole are collinear; larger compressing force and a larger compressing area are available, when the bucket is subject to impact and shake, good initial tension of a nut is guaranteed, the nut is effectively prevented from becoming loose, the surface of the bucket is further compressed, and the bouncing effect and the retreat preventing effect are improved.
Description
Technical field
The utility model relates to a kind of pad of fastening screw trip bolt, specifically for noria, connects the screw fastening pad used of winnowing pan and elevator belt.
Background technique
Winnowing pan and elevator belt are the critical pieces of noria, winnowing pan, for holding the powdery of loose thickness, granular, little lump material, is usingd traction belt as dirivig member, by elevator belt continuance lifting, carries, between winnowing pan and elevator belt, be connected by screw, what match with screw is nut and pad.
The frequency bumping in the actual moving process of noria due to winnowing pan is very high, thus the requirement of retaining far above general fastening occasion, and the damaged location of winnowing pan is mostly the breakage of the screw hole of side.In existing noria, the fastening means of winnowing pan generally adopts screw, nut and flat gasket to add elastic washer or common drum type spacer mode, the requirement that this can not meet the locking of winnowing pan and increase working life, easily cause nut to be in operation and be hit and shake to produce and become flexible, and the breakage of the side screw hole of the winnowing pan that brings of impact repeatedly, cause winnowing pan damage and promote with holes be elongated to draw wear phenomenon, affect working life and equipment reliability of operation and the Security of winnowing pan, elevator belt.
Summary of the invention
The purpose of this utility model is the oval drum type spacer adopting while providing a kind of Bucket of Bucket Type Elevator rational in infrastructure, that using effect is good to install in order to solve the problem of prior art existence.
The technical solution adopted in the utility model is: the utility model is by the identical top structure of continuous thickness, transition connecting structure and turn over and stick up structure and form, turning over, to stick up between structure and top structure be transition connecting structure, the topmost part middle is circular top structure, the middle of top structure is circular mounting hole, lower-most edge is to stick up structure towards turning over of top arc bending, it is conical that the vertical axial cross section of transition connecting structure is, horizontal radial cross section ovalize, turns over the also ovalize of radial cross section that sticks up structure; Top structure, transition connecting structure and turn over and stick up the vertical center axis of structure and the vertical center axis conllinear of mounting hole.
The utility model can increase the unexistent bounce-back of traditional flat gasket and retaining effect, and than the larger impacting force of common drum type spacer with compress area, adapts to better different mounting holes apart from the distance to the side margin of winnowing pan.When winnowing pan is impacted and shake, all the time can guarantee that nut has good preliminary tension, when effectively preventing nut loosening, compress further winnowing pan surface, the winnowing pan material deformation that stops its compression, significantly improves working life and equipment reliability of operation and the Security of winnowing pan, elevator belt.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is the plan view of Fig. 1;
?in figure: 1. transition connecting structure; 2. turn over and stick up structure; 3. top structure; 4. mounting hole.
Embodiment
As shown in Figure 1-2, the utility model is by continuous top structure 3, transition connecting structure 1 and turn over and stick up structure 2 and form, and the thickness of this three part-structure is all identical.Top structure 3 is positioned at position, middle, top of the present utility model, is circular, and the middle of top structure 3 is circular mounting holes 4, and mounting hole 4 matches with the size of screw, and the central shaft of mounting hole 4 vertically downward.Turn over and stick up structure 2 and be positioned at lower-most edge of the present utility model, to stick up between structure 2 and top structure 3 be transition connecting structure 1 turning over, and it is conical that the longitudinal section of the vertical axial of transition connecting structure 1 is, the cross section ovalize of horizontal radial.Turn over that to stick up structure 2 are the utility model edge structures, turn over and stick up structure 2 towards top arc bending, the cross section that turns over the horizontal radial that sticks up structure 2 is ovalize also.The central shaft that top structure 3, transition connecting structure 1 and turning over sticks up structure 2 is identical, with the central shaft conllinear of mounting hole, and equal Vertical direction.
The utility model can be formed by a metallic material after mould punching, and centre is stamped into the oval drum type that raises into certain altitude, the middle top structure 3 that is positioned at top of drum type, and drum type surrounding is to the same direction of top structure 3, to turn over turning over of sticking up to stick up structure 2.Turning over the outermost edge of sticking up structure 2 is 1:5～7 apart from the minimum vertical height h of horizontal bottom and the end face of top structure 3 apart from the ratio of the vertical overall height H of horizontal bottom, vertical overall height H is also height overall of the present utility model, and the diameter d of mounting hole 4 is 1:4～6 with the ratio that ellipse turns over the long axis length D that sticks up structure 2.
The utility model in use, oval-shaped profile can adapt to different mounting holes better apart from the distance to the side margin of winnowing pan, joining material self character again, the fastening force of attaching nut and bullet pad, when winnowing pan is impacted and shake, all the time can guarantee that nut has good preliminary tension, when effectively preventing nut loosening, further compress winnowing pan surface.Edge is turned over and is stuck up slightly upward, guarantees moving freely when being stressed, and prevents from that edge is stuck on the surface of winnowing pan when stressed to damage winnowing pan.
