Abstract
Disclosed are a polyurethane screen plate with a self-locking function and an installation structure thereof. The polyurethane screen plate with the self-locking function and the installation structure are used for solving the problem that an existing screen plate is prone to loosening, and screen holes and installation through holes are formed in the screen plate. The polyurethane screen plate is characterized in that the installation through holes are conical holes which gradually shrink from top to bottom. The installation through holes are distributed in the four corners of the screen plate or the two side edges of the screen plate. The installation structure of the polyurethane screen plate comprises installation cross beams and the polyurethane screen plate, and the installation cross beams are a part of a vibration screen. The installation structure is characterized in that the installation structure further comprises quick conical fastening components, the quick conical fastening components are installed in the conical holes of the screen plate and enable the screen plate to be fixed onto the installation cross beams. In the working process, due to the fact that high-frequency vibration of the vibration screen is complex movement, force is decomposed at the conical matching positions, and therefore bolts at the connecting positions are prevented from dropping.
Description
Technical field
The utility model relates to the sieve plate technical field using in vibrating screening device, specifically a kind of polyurethane sieve plate and mounting structure thereof with self-locking function.
Background technology
China is a mining powers, but domestic all kinds of Mineral Processing Enterprises are also relatively backward at present, to polyurethane screen (plate) have lightweight, screening efficiency is high, low, easy for installation, the comprehensive benefit advantages of higher of plug-hole, anti-wear, shock resistance, tear-proof, life-span long (be stainless steel sieve plate 3～8 times), noise not, be widely used on the screening machine of the industries such as metallurgy, mine, coal.
At present, polyurethane sieve plate typically uses bolt and is directly fixed in vibratory sieve, at the default counterbore of sieve plate, fastening by securing member.This kind of mounting means exists a problem to be exactly, because vibratory sieve is all the time in dither state, so loosening situation easily appears in bolt connection piece.Need to carry out regular inspection, produce in order to avoid impact is normal.
Utility model content
The utility model provides a kind of polyurethane sieve plate and mounting structure thereof with self-locking function for solving the technical problem existing in known technology, first solve the easily loosening problem of connector that mounted sieve uses, reduce the maintenance cost in use procedure, reduce enterprise's production cost.
The technical scheme in the invention for solving the technical problem is: a kind of polyurethane sieve plate with self-locking function, and on described sieve plate, be provided with sieve aperture and through hole is installed, it is characterized in that, described installation through hole is the conical bore shrinking gradually from top to bottom.
Further, the arrangement of described installation through hole on sieve plate is: four corners at sieve plate arrange respectively one.
Further, the arrangement of described installation through hole on sieve plate is: two side edge at sieve plate arrange respectively one.
The mounting structure of above-mentioned polyurethane sieve plate, comprise crossbeam and above-mentioned polyurethane sieve plate are installed, described installation crossbeam is a part for vibratory sieve, it is characterized in that, also comprise taper Quick fastening assembly, described taper Quick fastening assembly is arranged in the conical bore of described sieve plate and sieve plate is fixed on described installation crossbeam.
Described taper Quick fastening assembly comprises the bolt and the expanding cone that are nested with each other, large end in described expanding cone is provided with the cross recess of radially offering, described expanding cone plug is in conical bore, and described bolt is from top to bottom successively through being fastened on and installing on crossbeam after expanding cone and conical bore.
Between described expanding cone and bolt, be also arranged with a conically shaped.
Described taper Quick fastening assembly comprises the expansion bolt and the expanding cone that are nested with each other, large end in described expanding cone is provided with the cross recess of radially offering, described expanding cone plug is in conical bore, and described expansion bolt is consolidated and installed on crossbeam by nut through expanding cone and conical bore rear thread section successively from top to bottom.
The beneficial effects of the utility model are: in the time connecting polyurethane sieve plate and crossbeam is installed, first by polyurethane sieve plate as between two crossbeams, then taper Quick fastening assembly is inserted in conical bore, owing to being wedge-like engagement between taper Quick fastening assembly and conical bore, polyurethane sieve plate will clamp like this, form a kind of tight fit relation, and just can realize locking by controlling the pretightning force of bolt, by sieve plate being fixed on installation crossbeam tightly.In the course of the work, because the high-frequency vibration of vibratory sieve is complicated motion, power is decomposed at taper fit place, prevents that coming off from appearring in the bolt of junction.
Along with the growth of service time, the cooperation place between sieve plate and crossbeam can produce micro-gap, need to regularly safeguard, while maintenance, by bolted once, very convenient.Can greatly improve equipment operation rate, reduce plant maintenance and maintenance time, enhance productivity.
