When hydraulic force pushes the rotating mechanism to rotate through the connecting rod, the sweeping block subassembly is driven to rotate and compresses a rubber belt, the torque of a rotating arm can be automatically adjusted along with abrasion of the sweeping block, and keeps constant, and a contacting section of the sweeping block and the rubber belt is not changed. In addition, the sweeper has the advantages of simple structure, convenience in installation, high sweeping effect, long service life and the like.
Description
Technical field
A kind of device for coal mine belt conveyor cleaning load-transfer device.
Background technology
Belt conveyer is the crucial transportation device in coal production, and heavy section swabbing pig is the requisite corollary apparatus of belt conveyer, it is installed on belt conveyer head head roll dead ahead or coal unloading drum below, be used for cleaning and after belt conveyer is unloaded coal, stick to the coal slime residue on adhesive tape driving surface, and make it fall into head hopper.The friction force that is dependence adhesive tape and drive roll due to belt conveyer carrys out transferring power, thereby the effect of tape surface cleaning, directly has influence on service life and the smooth operation of belt conveyer.Along with the fast lifting of comprehensive mechanical coal mining technical merit, the running velocity of belt conveyer and transport capacity also further strengthen, if swabbing pig cleaning effect is bad, coal slime residue enters on cylinder and tape contact face, can cause rubber belt from deviating, skid, aggravate adhesive tape wearing and tearing simultaneously, when serious, can cause substantial equipment accident.
At present, the swabbing pig using in coal mine belt conveyor is spring loaded and weight hammer type structure, they are to utilize spring force and weight power that cleaning board is pressed on adhesive tape, simple in structure, by the coal slime residue on clear band plate scraping adhesive tape, but in real work, there are a lot of problems, as poor in modulability, replacement frequency is high, maintenance load is large, degree of automation is low, production efficiency is low; Under the effect of spring force and weight, adhesive tape and thrust and the cleaning power of cleaning between piece are unstable, and reduce gradually along with the wearing and tearing of cleaning piece, make that the scraper plate rate of wear is fast, the life-span is short, cleaning weak effect.
Summary of the invention
1. technical solution problem
Poor for current existing swabbing pig controllability, replacement frequency is high, maintenance workload is large, cleaning weak effect, the shortcomings such as service life is short, the invention provides the heavy section of a kind of belt conveyer hydraulic permanent moment swabbing pig, it can be along with the wearing and tearing at work of cleaning piece, after can realizing the wearing and tearing of auto-compensation cleaning piece and the gap producing between adhesive tape, and make to clean and between piece and adhesive tape, keep constant contact force and cleaning power, can reduce the wearing and tearing with adhesive tape, reach desirable cleaning effect, extend the service life of swabbing pig, travel switch has been installed simultaneously on swabbing pig, in the time that cleaning piece may wear to end position, pivot arm can touch travel switch, makes belt conveyer auto-stop, avoids swabbing pig metal piece damage adhesive tape or causes equipment breakdown.
2. technical scheme
The technical solution adopted for the present invention to solve the technical problems is: this swabbing pig forms by cleaning block assembly, rotating mechanism, guide piece, hydraulic efficiency pressure system, travel switch and fixed mount, and wherein, cleaning block assembly comprises cleaning piece, slotted-angle shelving; Rotating mechanism comprises pivot arm, stay bearing plate and brace panel; Guide piece comprises jam nut, guide head, connecting rod, disk spring and adjustment pad; Hydraulic efficiency pressure system comprises hydralic hose, hydraulic actuating cylinder and energy storage.Cleaning piece and slotted-angle shelving are bolted to be integrated and form cleaning block assembly, in order to guarantee to clean the intensity of block assembly, strengthen gusset 10 of the uniform welding in the back side of slotted-angle shelving; The integrally welded formation rotating mechanism of stay bearing plate, brace panel and pivot arm; Cleaning block assembly is fixed together by bolt and rotating mechanism; Rotating mechanism is connected with fixed mount and connecting rod respectively by two bearing pins again, and the other end of connecting rod is connected with the piston rod in hydraulic actuating cylinder; Adjusting pad sheet, disk spring, guide head are housed in connecting rod, finally locked with jam nut, to guarantee that spring has enough elastic force, once cleaning piece touches the place of adhesive tape breakage, cleaning piece is under this elastic force effect, will loosen compression adhesive tape, thereby make the place of adhesive tape breakage smoothly by cleaning piece, to avoid swabbing pig to sustain damage; On hydraulic actuating cylinder, be welded with adapter plate, and be fixed on fixed mount by bolt; Energy storage is also fixed on fixed mount, is communicated with, to be used for the pressure of compensating hydraulic cylinder plunger shaft by hydralic hose with hydraulic actuating cylinder cavity of resorption.In the time that hydraulic coupling promotes rotating mechanism rotation by connecting rod, will drive cleaning block assembly to rotate, make to clean piece and compress the gap producing after adhesive tape compensate for wear.The moment acting on pivot arm due to connecting rod is constant, and the radius of pivot arm is also constant, and therefore, cleaning piece is also invariable all the time to the thrust of adhesive tape; Travel switch is also fixed on fixed mount by bolt; in the time that the angle of rotating mechanism swing reaches maximum permission angle; to touch travel switch action; belt conveyer will auto-stop; staff should change cleaning piece in time, avoids swabbing pig metal piece damage adhesive tape or causes equipment breakdown.
3. beneficial effect of the present invention
The present invention can guarantee that cleaner has constant thrust and cleaning power, and hydraulic coupling also makes all the time to clean piece and compresses adhesive tape, thereby improve the stability of work, guarantee the auto-compensation of wearing clearance, simultaneously, the length of effectively wearing and tearing cleaning piece also strengthens, and has further improved the service life of cleaning piece; In addition, this swabbing pig also has simple in structure, and Installation and Debugging and replacing are convenient, and maintenance workload is little, degree of automation and work efficiency high.
