Abstract
Have polyurethane sieve plate and the mounting structure of self-locking function, for solving the problem that existing sieve plate easily gets loose, described sieve plate is provided with sieve aperture and installs through hole, it is characterized in that, described installation through hole is the conical bore shunk gradually from top to bottom.Through hole is installed and is distributed in four corners on sieve plate or two side edge.The mounting structure of above-mentioned polyurethane sieve plate, comprise and 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 by sieve plate and is fixed on described installation crossbeam.In the course of the work, the high-frequency vibration due to vibratory sieve is complicated motion, and power is decomposed at taper fit place, prevents the bolt of junction from occurring coming off.
Description
Technical field
The present invention relates to the sieve plate technical field used 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 current domestic all kinds of Mineral Processing Enterprises also backwardness relatively, to polyurethane screen (plate) have lightweight, screening efficiency is high, not low, easy for installation, the comprehensive benefit advantages of higher of plug-hole, anti-wear, shock resistance, tear-proof, life-span long (being 3 ~ 8 times of stainless steel sieve plate), noise, 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, namely presets counterbore at sieve plate, fastening by securing member.There is a problem and be exactly in this kind of mounting means, because vibratory sieve is in dither state all the time, so situation about loosening easily appears in bolt connection piece.Need to carry out regular inspection, produce in order to avoid impact is normal.
Summary of the invention
The present invention provides a kind of polyurethane sieve plate and the mounting structure thereof with self-locking function for solving in known technology the technical problem that exists, first the problem that the connector solving mounted sieve use easily loosens, reduce the maintenance cost in use procedure, reduce enterprise's production cost.
The present invention solves the technical scheme that its technical problem takes: a kind of polyurethane sieve plate with self-locking function, and described sieve plate is provided with sieve aperture and installs through hole, it is characterized in that, described installation through hole is the conical bore shunk gradually from top to bottom.
Further, the arrangement of described installation through hole on sieve plate is: arrange one respectively in four corners of sieve plate.
Further, the arrangement of described installation through hole on sieve plate is: arrange one respectively in two side edge of sieve plate.
The mounting structure of above-mentioned polyurethane sieve plate, comprise and 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 by sieve plate and is fixed on described installation crossbeam.
Described taper Quick fastening assembly comprises the bolt and expanding cone that are nested with each other, the cross recess radially offered is provided with at the large end of described expanding cone, described expanding cone plug is in conical bore, and described bolt is installed on crossbeam through being fastened on after expanding cone and conical bore from top to bottom successively.
A conically shaped is also arranged with between described expanding cone and bolt.
Described taper Quick fastening assembly comprises the expansion bolt and expanding cone that are nested with each other, the cross recess radially offered is provided with at the large end of described expanding cone, described expanding cone plug is in conical bore, and described expansion bolt is being installed on crossbeam by nut is solid through expanding cone and conical bore rear thread section from top to bottom successively.
The invention has the beneficial effects as follows: when connecting polyurethane sieve plate and installing crossbeam, 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, such polyurethane sieve plate will clamp, 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, the high-frequency vibration due to vibratory sieve is complicated motion, and power is decomposed at taper fit place, prevents the bolt of junction from occurring coming off.
Along with the growth of service time, the cooperation place between sieve plate and crossbeam can produce the gap of trace, needs regularly to safeguard, when safeguarding, by bolted once, very convenient.Greatly can improve equipment operation rate, reduce plant maintenance and maintenance time, enhance productivity.
