Description
Technical field
The present invention relates to the wedge shapes of the plate and frame sieve on the vibrating screen used in the industries such as a kind of oil, mine, metallurgy
Fast tensioning device.
Background technology
Sieve is the critical piece of vibrating screen screening solid phase particles, plays the role of throwing particle, sizing screening.Sieve exists
Compass screen surface is prone to wear out in screening process, needs to frequently replace sieve, therefore fast tensioning device is to improving vibrating screen working efficiency
It has a major impact.Traditional sieve tensioning mode is roughly divided into bolt tightening type, voussoir compression type and shaft and rolls tightly three kinds of formula,
In it is most widely used with voussoir compression type, the tensioning mode generally use manually tap promotes wedge block to move, pass through voussoir
Pressure fixing sieve.In double-deck screen shale shaker or the vibrating screen of step screen network arrangements form, lower screen is compressed using voussoir
Formula, it is difficult to carry out the wedging and disassembling section of voussoir.
In order to solve the problems, such as existing for wedge block compression mode, patent 2015204924371 discloses a kind of suitable for shaking
The tension-type voussoir pressing device of dynamic sieve installs wedge block in vibrating screen side plate inner wall, and screwing bolts make voussoir generate inclined-plane
Pressure, which is realized, compresses compass screen surface, but fixes a face sieve and need multiple pressing devices, therefore when design dismounts at the scene but has
It is inconvenient.Rotation is arranged in a kind of drilling fluid vibrating sieve frame screen cloth fixing device of patent 201510007094.X outside screen box
Driving wheel, driving wheel band carry-over bar and wedge block move, and pressed seat forces wedge block to move down and compresses frame screen cloth, which sets
The wedge block upper gear rack of meter is arc-shaped, and in assembling and dissembling process, the centre-to-centre spacing of gear and rack is not fixed, and wedge block will fall off, often
Secondary assembly and disassembly will reinstall wedge block.Patent 2016203066005 proposes a kind of vibrating screen frame screen cloth fast compressing device,
Operation principle is that installation compresses pawl on the outside of eccentric shaft, and rotation eccentric axis makes compression pawl band dynamic voussoir movement further fix frame
Sieve, the method ignore the locking design of pressing device, and the vibrating screen middle exciting force that works long hours will make eccentric shaft generate loosening,
Sieve cannot finally be fastened.
The shortcomings that overcome above-mentioned wedge block tensioning apparatus, spy propose a kind of wedge shape of plate and frame sieve of the present invention quickly
Tensioning apparatus.
Invention content
It is an object of the invention to overcome the shortage of prior art, a kind of quick tensioning dress of the wedge shape of plate and frame sieve is provided
It sets, by optimizing the structure of wedge-shaped fast tensioning device, is asked with solving low, secured effect difference of existing tensioning apparatus working efficiency etc.
Topic.
To achieve the above object, present invention employs following technical solutions.
A kind of wedge-shaped fast tensioning device of plate and frame sieve of the present invention, by wedge block, open rectangle pipe, wedge-shaped rack, tooth
Wheel shaft, plate and frame sieve, sieve supporting beam, gear shaft support base, sieve box side plate composition.
The wedge block, sieve supporting beam are fixedly connected on sieve box side plate, and Open Side Down and is welded on for open rectangle pipe
On wedge block；It is a certain included angle between wedge block and sieve supporting beam, the maximum value of the angle is no more than wedge-shaped rack and wedge block and sieve
The permitted angle of friction of net supporting beam material；Wedge-shaped the used key groove of rack and the angle phase between wedge block and sieve supporting beam
Together, the small end side on upper part inclined-plane opens up the gear teeth, and the length that the gear teeth open up section must assure that wedge-shaped rack can be by wedging, wedge
Symmetrical groove is opened up on the two sides of shape rack, the upper plane of groove is parallel with the wedge-shaped upper inclined surface of rack；Open rectangle
Pipe clamp enters the groove on the two sides of wedge-shaped rack, and groove makes wedge-shaped rack keep more solid with gear shaft in moving process
Fixed centre-to-centre spacing.
The gear shaft support base is fixedly connected on sieve box side plate, and gear shaft is mounted on gear shaft support base, wheel
Tooth and the gear teeth meshing on wedge-shaped rack drive wedge-shaped rack to be moved to the left, wedge-shaped rack when gear shaft rotates clockwise
By wedging, to which plate and frame sieve is compressed by wedge-shaped rack；When gear shaft rotates counterclockwise, wedge-shaped rack is driven to move right
Dynamic, wedge-shaped rack is relaxed, to which plate and frame sieve is relaxed.
The wedge block is of an L-shaped structure, and vertical part is fixedly connected with sieve box side plate, and lower part keeps flat part stage casing and opens up
The notch of one fixed width, while opening up the corresponding position of notch in the top of open rectangle pipe and wedge block lower part and opening up equal length
Notch, to ensure that gear shaft and the gear tooth portions of wedge-shaped rack can engage.
The advantage of the invention is that：（1）It can be by the torque size of control turning gear wheel shaft, more accurately in fastener cycle
Ground controls the tensioning pressure needed for voussoir.（2）In assembling and dissembling process, wedge block will not fall off, and can guarantee wheel and rack have compared with
Fixed centre-to-centre spacing, operation is light, and sieve is replaced efficient.（3）It is simple and compact for structure, taken up space smaller, installing and dismounting letter
Just, the vibrating screen especially suitable for screen box narrow space.
