Abstract
The utility model discloses the load-shedding equipment used in a scraper conveyor of a mining line pan with no soleplate. The utility model is characterized in that the structure of three scraping plates of a scraper chain of the original scraper conveyer are changed, and therefore, the resistance of a ground chain is small; the power consumption is little; the operation is more facile; a large amount of coal resource is saved, and the recovery ratio is increased; the mechanical failure is reduced by 53%, and the maintenance cost is reduced by 64%. Meanwhile, the utility model has the advantages of simple structure, convenient installation and operation, etc.
Description
The utility model relates to a kind of mining intermediate channel does not have the load-shedding equipment of using on the slat conveyer of base plate.
Now the intermediate channel of Shi Yonging does not have the various slat conveyer of base plate, all exists because of the chain resistance excessive interruption of service that causes in the end is many serious shortcoming that inefficient power consumption is big, the lighter wastes electric power, weight person's machinery can not normal operation, because accident is many, causes service expenditure to increase.
Through actual measurement, a SGW-40T type slat conveyer in the use, laying 70m along the tunnel level is 2.4 times of rated current because of end chain resistance makes load current greatly, on the intermediate channel during coal this machine just push down automatically, this phenomenon has caused many unfavorable factors for the normal operation of slat conveyer, because of the mechanical overload that end chain resistance causes greatly, often as seen the phenomenon that motor overheating burns makes slat conveyer be difficult to guarantee normal operation.
The purpose of this utility model is that a kind of load-shedding equipment that the chain resistance is little at the bottom of the mine flight conveyer, power consumption is few, mechanical wear is little, go slick that makes will be provided.
The utility model purpose is to realize like this, on the scraper chain of original slat conveyer, changed the structure of three scraper plates, laterally weld the identical triangle metal sheet of three block sizes on its first order scraper plate successively, laterally weld the identical triangle metal sheet of four block sizes on the scraper plate of the second stage successively, horizontal welding one block length square metal plate on the third stage scraper plate, the size of its triangle metal sheet and oblong metal sheet to be scraping head, tail and intermediate channel, and guarantee resistance little be principle.
The utility model is owing to changed the structure of three scraper plates on original mine flight conveyer, make that its end chain resistance is little, power consumption reduces, it is more flexible to turn round, through actual measurement, a SGW-40T type slat conveyer, horizontal laying length 40m, adding the preceding working current of this device is 21A, add with 15 minutes after-currents of this device and drop to 18.5A, owing to add and use this device, do not lose the triangle coal, saved a large amount of coal resources, improved the rate of extraction, mechanical breakdown reduces by 53%, and service expenditure has reduced by 64%, adds to install with this that back medium-sized mine can be saved various expenses every year and resource value can reach more than 500,000 yuan.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is for mine flight conveyer load-shedding equipment intermediate channel and scrape the board connecting structure cut-away view.
Fig. 2, Fig. 3, Fig. 4 are respectively the structural representation of first, second, third grade of scraper plate.
Describe concrete structure of the present utility model and condition of service in detail below in conjunction with accompanying drawing, this load-shedding equipment is the structure that has changed three scraper plates on the scraper chain of original slat conveyer, its first order scraper plate (4) is gone up and is laterally welded the identical triangle metal sheet of three block sizes (5) successively, second stage scraper plate (6) is gone up and is laterally welded the identical triangle metal sheet of four block sizes (7) successively, third stage scraper plate (8) is gone up horizontal welding one block length square metal plate (9), its triangle metal sheet (5), (7) and the size of oblong metal sheet (9) not scrape head, tail and intermediate channel (1), and guarantee resistance little be principle.
With SGW-40T type slat conveyer is example, first and second grade scraper plate (4), (6) are equicrural triangle for triangle metal sheet (5), (7) of welding, bottom side length 100mm, height are 30mm, the thick 20mm of being, the triangle metal sheet (5) that is welded on first order scraper plate (4) is 70mm apart from the distance at scraper plate (4) two ends; The triangle metal sheet (7) that is welded on the second stage scraper plate (6) is 20mm apart from the distance at scraper plate (6) two ends; The oblong metal sheet (9) that is welded on the third stage scraper plate (8) is a cleaning board, the wide 400mm of plate, high 25mm, is 20mm apart from the distance at scraper plate (8) two ends; Sequence of erection: will be divided into trisection with slotted ring (2), garden ring (3) bonded assembly scraper chain length overall on the slat conveyer, at first Along ent first order scraper plate (4) is installed, after start 5 weeks of operation, at second Along ent second stage scraper plate (6) is installed again, move the identical time, third stage scraper plate (8) is installed again, is reached after moving 50 minutes altogether and give the phase effect, three grades of scraper plates will be installed successively as stated above to prevent that unexpected resistance from increasing and produce fault.
Other model slat conveyer can be according to above-mentioned principle and method, changes the quantity and the size of triangle metal sheet on the scraper plate according to the specification of material and chain, plate.
