Description
Affiliated technical field
This patent relates to the production and the application engineering of conveying machinery equipment.
Background technology
Belt conveyer is the visual plant that mine is produced, heavy section swabbing pig (also claiming the head swabbing pig) is the indispensable accessory device of belt conveyer, it is installed on conveyor head head roll forward (FWD) the place ahead or discharge roll below, stick to residue on the load-transfer device in order to cleaning, and make it fall into the head hopper.Because conveyer is to rely on the friction force of load-transfer device and head roll to come transfer motion power, thereby the cleaning effect of load-transfer device has a significant impact service life and the conveyer smooth operation that prolongs load-transfer device, especially heavy type belt conveyor, because its running velocity is fast, transport capacity is big, if the cleaning effect is bad, dung enters head roll and tape contact face, cause rubber belt from deviating, skid, can aggravate the load-transfer device wearing and tearing simultaneously, cause the substantial equipment accident when serious.
At present, employed swabbing pig mostly is structures such as weight hammer type, spring loaded on the mine belt conveyor, and they are to utilize weight or spring that scraper plate is pressed on the load-transfer device, by the dung on the scraper plate scraping adhesive tape.But in real work, have many problems, poor as modulability, change the frequency height, maintenance workload is big; Under weight gravity or spring force effect, adhesive tape and the cleaning contact pressure (thrust) of interblock and tangential force (cleaning power) is unstable and reduce gradually along with the wearing and tearing of cleaning piece make that the scraper plate rate of wear is fast, and the life-span is short, cleans weak effect etc.At these problems, we develop and develop the heavy section of the adjustable constant force square of an a kind of belt conveyer swabbing pig, to improve the serviceability of swabbing pig; improve the cleaning effect; increase the service life, reduce fault power time, improve its work efficiency and degree of automation.
Summary of the invention
The technical matters that solves
Poor at present head swabbing pig controllability, life-span is short, shortcomings such as cleaning weak effect, the utility model provides a kind of belt conveying chain-drive section constant force square adjustable swabbing pig, this swabbing pig belongs to the first road swabbing pig, it can clean the gap that produces between piece wearing and tearing back and the adhesive tape by automatic compensation, makes the thrust of cleaning piece (being also referred to as scraper plate) keep constant, thereby has guaranteed to clean the constant of power; Secondly, can accurately regulate the size of cleaning power according to the adhesive tape running velocity, the wearing and tearing of minimizing and adhesive tape reach desirable cleaning effect; Once more, on swabbing pig, be provided with travel switch, when the cleaning piece may wear to end position, auto alarm, cleaning piece or shutdown are handled, are changed in prompting.Avoid swabbing pig metal piece damage adhesive tape or cause equipment breakdown.
Technical scheme
The technical scheme that its technical matters that solves the utility model adopts is: this swabbing pig is made up of cleaning block assembly, rotating mechanism, take-up device and fixed mount etc., and wherein, the cleaning block assembly comprises cleaning piece, slotted-angle shelving; Rotating mechanism comprises cover plate, carriage, pivot arm, rotating shaft; Take-up device comprises pull bar, pull bar axle sleeve, fixed pulley, movable pulley, steel rope and counterweight.Cleaning piece and slotted-angle shelving bolt together are one, and by being bolted on the carriage, only need adjust the length dimension of cleaning piece and slotted-angle shelving thereof, can satisfy the requirement of different size conveyer; Carriage is connected with rotating shaft by key with pivot arm, and rotating shaft is inserted in the axis hole of fixed mount, for guaranteeing the support strength of carriage, with bolt cover plate is fixed on the carriage.The rotation drive carriage and the cleaning piece of pivot arm rotate, and make the cleaning piece compress the also gap of compensation cleaning piece wearing and tearing back generation of adhesive tape; Pull bar is packed in the pull bar axle sleeve endoporus, the one end passes the square hole of pivot arm below, the end is connected with roller with bolt, the other end is adorned one group of movable pulley, fixed pulley axis is welded on the fixed mount, fixed pulley is contained on the fixed pulley axis, and travel switch is fixed by bolts near on the fixed mount of pull bar axle sleeve one side.When counterweight gravity by assembly pulley pulling pull bar in the pull rod shaft trepanning when mobile, by the rotation of roller compressing pivot arm, make the cleaning piece compress adhesive tape, simultaneously, because the moment that pull bar acts on the pivot arm is constant, the carriage radius of rotation is constant, thereby the cleaning piece also keeps constant to the thrust of adhesive tape.After the installation, can be according to the requirement of adhesive tape running velocity, the size of Field adjustment counterweight, when satisfying different running velocity to the requirement of cleaning power.When the pivot arm pendulum angle reaches maximum when allowing angle, will touch travel switch, in time handle and change by the alarm staff, avoid direct contact of parts such as slotted-angle shelving and damage adhesive tape or cause the accident with adhesive tape.
Beneficial effect
The beneficial effects of the utility model are: realized cleaning piece constant to the thrust of adhesive tape and cleaning power, kept the stable of cleaning effect; Counterweight forces makes the cleaning piece compress adhesive tape all the time, has guaranteed the automatic compensation of wearing clearance, and the cleaning piece length of effectively wearing and tearing is bigger, the service life of having improved the cleaning piece; By regulating counterweight and changing the length dimension of cleaning piece and slotted-angle shelving thereof, can satisfy the cleaning requirement that moves under the various belt speed, and good to the comformability of the conveyer of different size.This swabbing pig is simple in structure, Installation and Debugging and replacing convenient, the safe reliability height, and maintenance workload is little, degree of automation and high efficiency.
