Description
Technical field
The present invention relates to vibrating screens, in particular to vibrating screen mesh rail chair and combination of screens structure and installation method.
Background technology
Vibrating screen is the equipment for screening materials carrying, and sieve is equipped in vibrating screen host, and sieve is driven by host, then
It drives material to be vibrated in advance, accelerates the sieve pore that material penetrates sieve.There are many kinds of the forms of sieve, by material point, there is gold
Belong to sieve and non-metal mesh.Also have based on metallic sieve, with the product of nonmetallic materials bound edge frame.Mounting means has bolt
It is firm, drag hook tensioning, cassette installation.Cassette installation is mainly used for non-metal mesh or nonmetallic frame sieve.Cassette sieve has
Multicolumn cassette, bolt cassette, expansion pin cassette, rail chair cassette.Rail chair cassette is divided into double rail type and monorail, and material can also be divided into gold
Category formula and nonmetallic formula.Multicolumn cassette such as CN201180025086.8 and CN201180068606.3, bolt cassette
CN00802832.X, there is a Geometrical Tolerance Principle in two degree of freedom, the installation of rail chair formula as CN201210216809.9,
CN200580031058.1 and CN201220536035.3 only has Geometrical Tolerance Principle, it is clear that from sieve in one degree of freedom
Production and sieve dismount convenience to compare, and only limit pin-type load of the rail chair formula of one degree of freedom all than limiting two degree of freedom
Want simple and convenient.There are two the multicolumn cassette of degree of freedom limitation, bolt cassette, expansion pin cassette etc., the mold requirement of production, contractions
Rate changes, and the hole of vibrating screen host screen-mesh mounting structure or the geometric tolerance of support plate are all more complicated, difficult, and installation is more difficult,
After often installing one side, there is deformation, dislocation in another side, it is difficult to device to hole.Only there is Geometrical Tolerance Principle in one degree of freedom
Rail chair formula produces simpler, mold, and shrinking percentage only considers that a direction, dismounting are also easier to, but also there are one lack for rail chair formula
Point, rail chair length direction section are consistent, i.e., only non-length direction one degree of freedom limitation, in the longitudinal direction degree of freedom
It is not restricted, (length direction) is caused in the freedom degree direction not limited to be difficult to accurate positioning.Vibrating screen host is in operational process
In, it constantly vibrates, sieve vibrated material forward direction is sieve length direction, and sieve has edge not limit in freedom degree direction
The trend of (length direction) sliding, and the sieve size that horizontally slips along its length is not necessarily consistent can lead to sieve deformation, wrong
, occur gap between sieve, generates material leakage etc..Although usually having plate washer stop in the front end of flood sieve, before most
Other sieves outside sieve still have forward trend.In the prior art, double track rail chair generally use track separates mode such as
CN200820073743.1, and the mode of the card slot corresponding position of sieve connection carries out sieve positioning.But on sieve using every
Disconnected mode is not most suitable mode, because the position of sieve respective carter partition is entity, sieve is caused to be caught in and split out
When it is highly difficult, or even need to destroy energetically and can just split out.It is therefore desirable to have new mode overcomes disadvantages mentioned above.
Invention content
It is above-mentioned to solve the problems, such as, vibrating screen variable cross-section sieve rail chair provided by the invention and combination of screens structure,
It solves rail chair formula screen-mesh mounting structure to exist, rail chair length direction is unrestricted, it is difficult to which the problem of being accurately positioned can prevent compass screen surface from altering
It is dynamic and easy for installation.Correspondingly, the present invention also provides a kind of vibrating screen variable cross-section sieve rail chair and combination of screens installation sides
Method.
The technical proposal for solving the technical problem of the invention is：Vibrating screen variable cross-section sieve rail chair and combination of screens knot
Structure, it is characterized in that：The track length direction cross sectional shape of the rail chair has expansion or contraction change, sieve accordingly to clamp position and cut
Face shape synchronizes hypertonic.I.e.：The track length direction cross sectional shape of rail chair has expansion to change, and sieve accordingly clamps position section shape
Shape synchronizes expansion, or：The track length direction cross sectional shape of rail chair has contraction change, and it is same that sieve accordingly clamps position cross sectional shape
Step is shunk, and is positioned on track length direction to realize.
" sieve accordingly clamps position cross sectional shape " described above, be sieve entity constituted can accommodate rail chair track
Cavity shape section.This cavity shape cross-sectional expansion can just hold the rail chair track of expansion, this cavity shape cross-sectional constriction is
The rail chair track of contraction, formation length direction positioning action can be adjacent to.
Vibrating screen variable cross-section sieve rail chair and combination of screens structure, are characterized in that, the track length direction section shape of rail chair
Shape has expansion or contraction change, sieve accordingly to clamp position cross sectional shape and synchronize hypertonic.
Further preferably, when the rail section of rail chair is shunk, sieve accordingly clamps the track of the length than rail chair at position
Cross-sectional constriction partial-length is short.
Further preferably, when the rail section of rail chair is expanded, sieve accordingly clamps the track of the length than rail chair at position
Section enlarged length is long.
Further preferably, it on the track length of the rail chair isometric with compass screen surface can be one section of cross sectional shape variation, it can also
It is the variation of multistage cross sectional shape.
Further preferably, within the scope of the hypertonic segment length of the track of each section of rail chair, rail section shape can remain unchanged,
Various transition, gradual change section can also be used.
Further preferably, the track variable cross-section part of rail chair, cross sectional shape are up big and down small clamping structure, upper big portion
It is rectangular, round, shape changeable or various abnormity to divide.
In order to avoid there is the limited situation of two degree of freedom, and lead to difficult to install, the track change section of sieve and rail chair
Face length can be with Length discrepancy.Specifically, when the rail section of rail chair is contraction mode, sieve accordingly clamps the length ratio at position
The rail section constriction length of rail chair is short；When the rail section of rail chair is expansion pattern, sieve accordingly clamps position
Length is longer than the rail section enlarged length of rail chair；In this way, sieve variable cross-section section is only needed towards discharging side and rail chair
It reclines, the other side has a small amount of gap, positioning action that can generate.And there is a small amount of shape position error between the sieve length,
Also because there is the gap of the other end, and there is certain adjusting leeway, it is difficult will not to occur assembly in the longitudinal direction.This gap is not
Must be excessive, it is intended merely to the deviation for overcoming sieve manufacture to generate and screen supporting structure generates deviation and sets.If it is compared with gross porosity
Sieve, a small amount of gap between sieve is can to receive, and screening effect is not influenced, if it is fine mesh, because front and back sieve has
Structure that overlapped up and down, is still not in leak phenomenon under the fines more than sieve pore.
The material of rail chair can be metal material, can also be nonmetallic materials, nonmetallic materials be mainly polyurethane and
Two kinds of rubber.Metal rail chair and polyurethane rubber rail chair have their own advantages and deficiency, and constituent parts are existing using metal, also use
Polyurethane and rubber.The advantage and disadvantage of metal rail chair：Metal rail chair is at low cost, can change it is big, but the deficiency of metal rail chair
Place is that he is hard with when the cooperation of polyurethane rubber sieve one soft one, and relative resilient is smaller, easy tos produce relative motion friction, leads
Sieve is caused to clamp not tight.Metal rail chair long slab, strip welding, geometric tolerance are difficult to guarantee, and weld seam can not be soldered to position between double track.Peace
Dress geometric tolerance is difficult to ensure.Sieve does not have seat board to hold, and sieve rigidity requirement is high.Variable cross-section is made in metal rail chair length
Effect, difficulty are larger.The advantage and disadvantage of polyurethane and rubber rail chair：Polyurethane rail chair and sieve are all soft to soft, and elasticity is more preferable, no
It is also easy to produce relative motion, installation is more firm, and card slot shape can be changeable, ensures to clamp securely, make in polyurethane rubber rail chair length
Go out variable cross-section effect to be relatively easy to.But the making of polyurethane rubber rail chair needs mold to process, and first current cost is slightly higher.
The material of sieve has polyurethane, and rubber, rubber and plastic class, it is metal net also to have sieve main part, pours into a mould poly- ammonia
Ester rubber border.It is made on frame and the matched shape of rail chair.
The structure of rail chair and sieve cooperation, typically up big and down small clamping structure, this structure can also be various.
The track variable cross-section part of rail chair, upper big portion cross-sectional shape are rectangular, round, shape changeable and various abnormity
Deng.
On one rail chair in the size isometric with sieve, there can be one or more variable cross-section parts, can also be sieved in flood
In the rail chair length of net, several variable cross-section parts are only distributed, is not necessarily intended to correspond to length in every piece of sieve and all arranges variable cross-section portion
Point namely flood sieve on, several pieces of sieves are distributed in length direction, be not necessarily intended on every piece of sieve arrange variable cross-section knot
Structure also only can arrange variable section structure, that is, flood sieve length direction is not every piece of sieve all limited lengths on the sieve of part
Direction degree of freedom, the limitation of less length direction degree of freedom, it is possible to reduce the degree of difficulty of production and installation can also generate enough
Length direction positioning action, make sieve will not forward slip.
The technique effect of the present invention：The structure of the present invention is simple, it is only necessary to change former rail chair track and sieve edge card slot
A part of section, so that it may generate prevent compass screen surface play effect.Sieve durability is improved, oversize material leakage is prevented, prevents sieve
