Description
Technical field
The utility model relates to the plate and frame sieves on vibrating screen used in the industries such as a kind of petroleum, mine, metallurgy
Wedge-shaped fast tensioning device.
Background technique
Sieve is the main component 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 raising 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, which generallys use artificial tap and promotes wedge block mobile, passes 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 vibration
The tension-type voussoir pressing device of dynamic sieve installs wedge block in vibrating screen side plate inner wall, and screwing bolts generate voussoir to 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.A kind of fixed device of drilling fluid vibrating sieve frame screen cloth of patent 201510007094.X, is arranged rotation 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 center of gear and rack gear is away from being 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,
Working 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 utility model
Fast tensioning device.
Summary of the invention
The purpose of the utility model is to overcome prior art deficiencies, provide a kind of wedge shape quickly tensioning of plate and frame sieve
Device, by optimizing the structure of wedge-shaped fast tensioning device, to solve low, secured effect difference of existing tensioning apparatus working efficiency etc.
Problem.
To achieve the above object, the utility model uses following technical solution.
A kind of wedge-shaped fast tensioning device of plate and frame sieve of the utility model, by wedge block, open rectangle pipe, chisel teeth
Item, gear 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 gear and wedge block and sieve
The permitted angle of friction of net supporting beam material；Wedge-shaped the used key groove of rack gear 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 gear can be by wedging, wedge
Symmetrical groove is opened up on the two sides of shape rack gear, the upper plane of groove is parallel with the wedge-shaped upper inclined surface of rack gear；Open rectangle
Pipe clamp enters the groove on the two sides of wedge-shaped rack gear, and groove makes wedge-shaped rack gear keep more solid with gear shaft in moving process
Fixed center away from.
The gear shaft support base is fixedly connected on sieve box side plate, and gear shaft is mounted on gear shaft support base, wheel
Gear teeth meshing on tooth and wedge-shaped rack gear drives wedge-shaped rack gear to be moved to the left, wedge-shaped rack gear when gear shaft rotates clockwise
By wedging, so that plate and frame sieve is compressed by wedge-shaped rack gear；When gear shaft rotates counterclockwise, wedge-shaped rack gear is driven to move right
Dynamic, wedge-shaped rack gear is relaxed, so that 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 lays flat part middle section 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 guarantee that gear shaft and the gear tooth portions of wedge-shaped rack gear can engage.
Utility model has the advantages that can be by the torque size of control turning gear wheel shaft, more in (1) fastener cycle
Tensioning pressure needed for accurately controlling voussoir.(2) in assembling and dissembling process, wedge block be will not fall off, and can guarantee wheel and rack
There is relatively fixed center away from operation is light, and sieve replacement is high-efficient.(3) simple and compact for structure, it takes up space smaller, installation is torn open
Simplicity is unloaded, the vibrating screen especially suitable for screen box narrow space.
