Abstract
The invention discloses a heavy sweeper which comprises a tensioning device, a telescopic cross beam, a sweeping blade and a bolt assembly, wherein the sweeping blade is connected with the telescopic cross beam through the bolt assembly, and the tensioning device comprises a fixed seat, a power twister, a damping sleeve and a screw slippery prevention lead screw. One end of the screw slippery prevention lead screw is connected with a fixed seat shaft, the other end of the screw slippery prevention lead screw is suspended, a power twister base is arranged in a fixed seat hole through the damping sleeve and fixedly connected with one end of the telescopic cross beam through a compression bolt in a sleeving mode, and a power twisting arm of the power twister is connected with the screw slippery prevention lead screw in a sleeving mode and fixed through a forward and backward rotation screw slippery prevention regulation nut and a spring. By means of the bolt assembly, replacement is more convenient. The blade still keeps tensile force stable on a belt under high-frequency vibration by means of the tensioning device, fatigue damage to a blade base is reduced, loss of tensile force caused by looseness of the nut is avoided, service life is prolonged, and tensioning of a knife edge can be regulated without disassembling the sweeper.
Description
Technical field
The present invention relates to a kind of swabbing pig, relate in particular to a kind of heavy swabbing pig.
Background technology
The material cleaning of conveyer unloading roller belt need to be used the residue on heavy swabbing pig cleaning belt, there is in use following subject matter in heavy swabbing pig in the market: 1, under belt running state, because causing cleaning blade, the shake of belt cannot be attached on belt, cause leaking coal or clear up not thorough, therefore clean weak effect, the fatigue damage of simultaneously shaking blade pedestal causes reduce service life; 2, because tightening device exists defect loosening under high-frequency vibrations, cause it to lose tensile force and cannot work and damage belt; 3, do not have Aseismatic Design or Aseismatic Design unreasonable, cause blade damage belt clamps, and belt is scrapped; 4, 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 structure design is unreasonable, easily occurs leaking coal, tears belt, damages belt clamps, pollutes the problems such as environment on coalface.
Summary of the invention
The object of the invention is to solve the aforementioned problems in the prior, and provides a kind of cleaning effective, does not leak material, does not damage the heavy swabbing pig of belt and belt clamps, long service life.
The present invention is for achieving the above object, and the technological means adopting is: a kind of heavy swabbing pig, comprise tensioner, flexible crossbeam, cleaning blade, bolt assembly, and described cleaning blade is connected with flexible crossbeam by bolt assembly; Described tensioner comprises 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 in one end of flexible crossbeam by push bolt, 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 cleaning blade is selected urethanes blade.
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 tensioner arranges two groups, is arranged on respectively on two telescopic girdeies at flexible crossbeam two ends.
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.
Further, described cleaning blade bottom arranges groove, and in blade lower end surface, deep gouge is set.
Beneficial effect of the present invention is: cleaning blade material selection urethanes, and the performances such as its high-wearing feature, high resiliency, fastness to water, fuel resistance are much better than polyurethane, and cleaning blade adopts bolt assembly to fix, and more allowing blade replacement is convenient; 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 the common fault of having corrected the hold-down nut of like product and lose after loosening 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 under belt is constantly shaken, can be attached to closely on belt, remain stable tensile force, and reduce the fatigue damage of shake blade pedestal, improve the service life of blade, and regulate the tensioning of the edge of a knife without dismounting swabbing pig.
