Abstract
The utility model discloses a heavy sweeper tensioning device. The heavy sweeper tensioning device comprises a fixing seat, a torque unit, a damping sleeve and an unscrewing-proof screw; one end of the unscrewing-proof screw is coupled to the fixing seat, the other end of the unscrewing-proof screw is suspended in the air; the base of the torque unit is mounted inside the hole of the fixing seat through the damping sleeve and fixed on a sweeper in a sleeve mode through a compression bolt, and the torque arm of the torque unit sleeves the unscrewing-proof screw and fixed through a rotating unscrewing-proof nut and a spring. The heavy sweeper tensioning device maintains a fastening state under high-frequency vibration and accordingly solves the problem that compression nuts loosen and lose tension, enables a blade to be close to a belt to main stable tension, reduces the fatigue damage to a blade base due to vibration and prolongs the service life of the sweeper; the damping sleeve provides secondary buffering to the sweeper and accordingly minimizes the damage to a belt buckle; a tension adjusting device can adjust the tension degree of the edge of the blade without disassembly of the sweeper and thereby facilitate usage and maintenance.
Description
Technical field
The utility model relates to a kind of heavy swabbing pig, relates in particular to a kind of heavy swabbing pig tightening device.
Background technology
The material cleaning of conveyer unloading roller belt need to be used the residue on heavy swabbing pig cleaning belt, heavy swabbing pig in the market cannot be attached on belt because the shake of belt causes cleaning blade in use, cause leaking coal or clear up not thorough, therefore clean weak effect, the fatigue damage of simultaneously shaking blade pedestal causes reduce service life.Trace it to its cause, subject matter is: loosening under high-frequency vibrations because of tightening device, and cause it to lose tensile force and cannot work, cause cleaning blade damage belt; Do not have Aseismatic Design or Aseismatic Design unreasonable, cause blade damage belt clamps, and belt is scrapped; And while regulating cleaning blade edge of a knife position, need to dismantle swabbing pig, operation and maintenance is all inconvenient.
In sum, existing heavy swabbing pig causes cleaning effect thorough not because tensioning device structure design is unreasonable, easily occurs leaking coal, tears belt, damages belt clamps, pollutes the problems such as environment on coalface, working service inconvenience.
Utility model content
The utility model object is to solve the aforementioned problems in the prior, and a kind of heavy swabbing pig tightening device is provided, and uses the heavy swabbing pig cleaning of this device effective, does not leak material, does not damage belt and belt clamps, long service life, easy to maintenance.
The utility model is for achieving the above object, the technological means adopting is: a kind of heavy swabbing pig tightening device, comprise permanent seat, power twister, damping sleeve, anti-back silk screw mandrel, one end of anti-back silk screw mandrel is connected with permanent seat axle, the other end is unsettled, power twister pedestal is arranged in permanent seat perforate by damping sleeve, and fixedly sleeved on swabbing pig by push bolt, and the toggle of power twister is socketed on anti-back silk screw mandrel and by positive and reverse return anti-back setting nut and spring and fixes.
Further, described push bolt arranges three, is positioned on the excircle of power twister pedestal.
Further, between described positive and reverse return anti-back setting nut and spring, be also provided with packing ring.
Further, one end that described anti-back silk screw mandrel is connected with permanent seat axle is fixed by pad and spring cotter.
Further, described damping sleeve adopts polyurethane damping sleeve.
Further, described permanent seat is installed uniform four connecting bores of perforate surrounding of damping sleeve, is positioned at anti-back silk screw axis and a connecting bore is set above connecting, for connecting belt feeder on central axis corresponding to four connecting bores.
The utility model beneficial effect is: the anti-withdrawing nut of positive and reverse return coordinate with anti-back silk screw mandrel allows tensioner under high-frequency vibration, keep confining loosening, thereby solved the hold-down nut of like product and lost after loosening the common fault of tensile force; Adding of polyurethane damping sleeve makes swabbing pig have secondary buffer effect, and blade has been dropped to minimum to the damage of belt clamps; The structure of tensioner uniqueness makes blade constantly under shake, still can be close on belt at belt, remains stable tensile force, and reduces the fatigue damage of shake blade pedestal, the service life of improving swabbing pig; Be the tensioning degree of the adjustable edge of a knife by regulating tightening device without dismounting swabbing pig, working service is more convenient.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: 1, permanent seat, 2, power twister, 3, damping sleeve, 4, anti-back silk screw mandrel, 5, push bolt, 6, spring, 7, positive and reverse return anti-back setting nut, 8, packing ring, 9, spring cotter.
Detailed description of the invention
The heavy swabbing pig tightening device of one as shown in Figure 1, 2, comprise permanent seat 1, power twister 2, damping sleeve 3, anti-back silk screw mandrel 4, one end of anti-back silk screw mandrel 4 is connected with permanent seat 1 axle, the other end is unsettled, power twister 2 pedestals are arranged in permanent seat 1 perforate by damping sleeve 3, and fixedly sleeved on swabbing pig by push bolt 5, the toggle of power twister 2 is socketed on anti-back silk screw mandrel 4 and by positive and reverse return anti-back setting nut 7 and spring 6 and fixes.
Described push bolt 5 arranges three, is positioned on the excircle of power twister pedestal.3 push bolts 5 are connected to power twister 2 and swabbing pig after one, regulate positive and reverse return anti-back setting nut 7, make spring 6 stress deformations, and the power control power twister 2 that recycling spring 6 recovers distortion rotates.
Between described positive and reverse return anti-back setting nut 7 and spring 6, be also provided with packing ring 8.
One end that described anti-back silk screw mandrel 4 is connected with permanent seat 1 axle is fixing by pad and spring cotter 9.
Described damping sleeve 3 adopts polyurethane damping sleeve.
Described permanent seat 1 is installed uniform four connecting bores of perforate surrounding of damping sleeve 3, is positioned at anti-back silk screw mandrel 4 axles and a connecting bore is set above connecting, for connecting belt feeder on central axis corresponding to four connecting bores.
The utility model utilize the anti-withdrawing nut of positive and reverse return to coordinate with anti-back silk screw mandrel to allow tensioner under high-frequency vibration, keep confining loosening, thereby solved the hold-down nut of like product and lost after loosening the common fault of tensile force; Adding of polyurethane damping sleeve makes swabbing pig have secondary buffer effect, and blade has been dropped to minimum to the damage of belt clamps; The unique texture that power twister 2, anti-back silk screw mandrel 4, positive and reverse return anti-back setting nut 7 and spring 6 coordinate makes blade constantly under shake, still can be close on belt at belt, remain stable tensile force, and the fatigue damage of minimizing shake blade pedestal, the service life of improving swabbing pig; Be the tensioning degree of the adjustable edge of a knife by regulating tightening device without dismounting swabbing pig, working service is more convenient.
