Abstract
The utility model provides a dual regulation type sweeper at the head of a heavy-duty belt conveyor, which can improve the sweeping effect and has longer service life. The sweeper mainly comprises sweeping blocks, sweeping block sleeves, a sweeping block bracket, an articulated frame, a hydraulic cylinder, a sectional shaft, a spring deflector rod, a spring adjustor and the like; and the sweeping block and the sweeping block sleeves are fastened and connected, and every two sweeping block sleeves, one articulated frame and a piston rod are connected into a whole, forming two groups totally. When abrading during working, the sweeping blocks are pushed to extend out by a constant hydraulic force provided by a static pressure cylinder to ensure that the sweeping blocks and an adhesive belt keep stable contact pressure and a stable sweeping force; the spring deflector rod is sleeved on the sectional shaft, and the other end thereof is inserted into the spring adjustor, and the sweeping blocks can swing with a certain angle through regulating adjusting screws at two ends of a box body of the spring adjustor, thereby regulating the position of the contact point of the sweeping blocks with the adhesive belt.
Description
Affiliated technical field
This patent relates to the production and the application engineering of conveying machinery equipment.
Background technology
Belt conveyer is that the high-yield and high-efficiency mine is realized the quantity-produced visual plant, and 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, still stick to residue on the load-transfer device driving surface after the discharging in order to cleaning, and make it fall into the head hopper.The cleaning effect of load-transfer device, to having a significant impact in the service life of prolongation load-transfer device and the smooth operation of twin-roll driving, especially heavy type belt conveyor, because its running velocity is fast, transport capacity is big, if the cleaning effect is bad, can causes rubber belt from deviating, skid, can aggravate the belt wearing and tearing simultaneously, cause equipment breakdown when serious.Employed swabbing pig is generally easy structure such as weight hammer type, spring loaded on the coal mine belt conveyor at present, they are to utilize weight or spring that scraper plate is pressed on the load-transfer device, simple in structure, but in real work, have many problems, poor as modulability, change the frequency height, maintenance load is big; Under weight gravity or spring force effect, adhesive tape and the contact pressure and the tangential force instability of cleaning interblock make that the cleaning piece rate of wear is fast, and the life-span is short, the cleaning weak effect; Degree of automation is low, and production efficiency is low etc., at these problems; we will develop and develop the two adjustable type swabbing pigs of a kind of heavy type belt conveyor head, to improve the serviceability of swabbing pig, improve the cleaning effect; 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 heavy type belt conveyor head two adjustable type swabbing pigs, this swabbing pig belongs to the first road swabbing pig, it can realize bidirectional modulation, can adjust the angle of cleaning piece swing, the cleaning piece is stretched out automatically along the adhesive tape direction, the gap that produces between compensation cleaning piece wearing and tearing back and the adhesive tape, make the cleaning piece with keeping stable contact pressure and cleaning power between the adhesive tape, the wearing and tearing of minimizing and adhesive tape reach desirable cleaning effect; The cleaning of this swabbing pig is packaged tears open conveniently, and stroke is big, to prolong its service life.
Technical scheme
The technical scheme that its technical matters that solves the utility model adopts is: this swabbing pig mainly is made up of cleaning piece, cleaning piece cover, cleaning piece support, body cradle, hydraulic actuating cylinder, hydraulic actuating cylinder carriage, built-up shaft, spring driving lever and spring-loaded governor etc.The cleaning piece connects as one with cleaning piece cover, and cleaning piece cover is connected by bearing pin with body cradle, and hydraulic cylinder piston rod also is connected with body cradle by bearing pin, and per two cleaning piece covers, a body cradle and a piston rod link into an integrated entity totally two groups.After the wearing and tearing of cleaning piece, rely on constant compression force in the hydraulic actuating cylinder, it is protruding to promote the cleaning piece, and the gap that produces between automatic compensation cleaning piece wearing and tearing back and the adhesive tape is to guarantee that cleaning piece contacts all the time with adhesive tape.
Between cleaning piece support with holes and the built-up shaft, between hydraulic actuating cylinder carriage and the built-up shaft, between hydraulic actuating cylinder carriage and the hydraulic cylinder body, Support bracket and built-up shaft and cleaning piece support all be integral by bolted connection, be fixed in then on the frame in the sealing-tape machine head-shield outside; Built-up shaft is made up of a channel-section steel, two solid drawn pipes and two solid minor axises, and sliding supported condition is adopted at its two ends; Make two spring driving levers of cleaning piece swing be set in two minor axis ends, the other end is inserted in respectively in two spring-loaded governors.By adjusting the set screw at two ends in the spring-loaded governor, can make spring driving lever rotating certain angle, thereby make the certain angle of cleaning piece swing.
Beneficial effect
The beneficial effects of the utility model are: realized two adjustings; can make the cleaning piece protruding automatically; can adjust the angle of cleaning piece swing again; not only clean effectively, and avoid adhesive tape to be torn, prolong the service life of swabbing pig and adhesive tape; reduce fault power time; easy for installation, regulate accurately, improved degree of automation and work efficiency.
