Description
Technical field
The present invention relates to mining load transfer device, be specially a kind of trailing type slat conveyer and jump chain sideslip power-off protection apparatus.
Background technology
Slat conveyer and band conveyor are two kinds of common transportation devices in coal preparation plant, and the feature such as compared with band conveyor, slat conveyer has good seal, and freight volume is large.Simultaneously the cost of slat conveyer and maintaining cost are also far above band conveyor.And unavoidably because wearing and tearing depth difference occurs that jumping the fault such as chain or sideslip occurs in long-term operation, owing to sealing completely, post driver usually can not in the abnormal condition of very first time discovering device.Just once occurred, because scraper plate occurs that the scraper plate that the fault discovery of jumping chain sideslip causes not in time and chain damage in a large number, even by the situation of burn-down of electric motor, causing the dynamo-electric power outage of more than ten hours in passing experience.For this reason; solve slat conveyer and occur that abnormal running finds that problem not in time becomes the key point that maintaining safeguarded by slat conveyer; and common break chain protector or spacing can only can be out of service when chain rupture appears in scraper plate, caused certain economic loss.
Summary of the invention
The object of this invention is to provide a kind of trailing type slat conveyer and jump chain sideslip power-off protection apparatus, shut down in time when there is the fault of jumping chain sideslip for slat conveyer, avoid larger loss.
The present invention adopts following technical scheme to realize:
Chain sideslip power-off protection apparatus jumped by a kind of trailing type slat conveyer, comprise the base on the crossbeam of the central slot being fixedly installed in slat conveyer, described base vertically installs vertical shaft by bearing, and the bottom of described vertical shaft connects one with pendulum, describedly stretches in middle cell body with pendulum; The indicator scale of a level is welded on the top of described vertical shaft; Described base arranges strut bar, and described supporting bar top is installed two parallel inductions and is shut down limit switches, and both sides above free end that limit switch is positioned at indicator scale are shut down in two inductions.
During use, install in the central slot of slat conveyer with pendulum, when in intermediate channel, convey materials passes through, scraper plate top contacts with putting, stir with pendulum, and the size of amplitude of fluctuation is passed to vertical shaft, vertical shaft can produce small vibration, vertical shaft upper end is that an angle of 90 degrees level welds an indicator scale, when normally running according to scraper plate, indicator scale amplitude of fluctuation size is installed induction and is shut down limit switch, this switch is connected with switchgear building, when cable chain appears in slat conveyer, when falling the abnormal operational conditions such as chain, slat conveyer tilts, the corresponding rotation of vertical shaft, indicator scale then reaches full swing position, any one in two induction shutdown limit switches can be blocked accordingly, and then trigger switch, cause scraping transporter out of service, thus reach the effect of power-off protection.
Said apparatus tool has the following advantages:
1, can the running condition of Simultaneous Monitoring slat conveyer.
2, the more major break down that slat conveyer finds there is cable chain, when falling the faults such as company to cause not in time is solved.
3, equipment cost is low, and structure is simple, is applicable to the slat conveyer in all posies.
4, compared with other break chain protector, this equipment just can stopping alarm before chain rupture does not appear in scraper plate, decreases unexpected generation.
This apparatus design is reasonable, can reduce the input quantity of scraper plate post personnel by actv., improve personnel's degree of utilization, also can avoid the generation of great scraper plate damage accident simultaneously, indirectly reduce the labour intensity of worker.

In figure, 1-base, 2-vertical shaft, 3-bearing, 4-is with pendulum, and 5-indicator scale, limit switch is shut down in 6-induction, and 7-strut bar, 8-limit spring, 10-central slot, 20-crossbeam, 41-cross bar, 42-swings skin, 43-counterweight.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are described in detail.
Chain sideslip power-off protection apparatus jumped by a kind of trailing type slat conveyer, as shown in Figure 1, 2, comprise the base 1 on the crossbeam 20 of the central slot 10 being fixedly installed in slat conveyer, described base 1 vertically installs a vertical shaft 2(vertical shaft by bearing rotation by upper and lower two bearings 3), the bottom of described vertical shaft 2 connects one with pendulum 4, describedly stretches in middle cell body 10 with pendulum 4; The indicator scale 5 of a level is welded on the top of described vertical shaft 2; Described base 1 arranges strut bar 7, and described strut bar 7 top is installed two parallel inductions and is shut down limit switch 6, two induction and shut down both sides above free end that limit switch 6 is positioned at indicator scale 5, as shown in Figure 3.The described both sides with pendulum 4 are connected with middle cell body 10 both sides respectively by limit spring 8, guarantee pendulum by mistake can not occur, and cause unnecessary shutdown.
During concrete enforcement, as shown in Figure 4,5, describedly comprise a cross bar 41 with pendulum 4, this cross bar can adopt angle bar, and described cross bar connects for 41 times and swings skins 42, and the two ends of described cross bar 41 arrange counterweight 43.The two ends of described cross bar 41 are connected with middle cell body 10 both sides respectively by limit spring 8, guarantee pendulum by mistake can not occur, and cause unnecessary shutdown, limit spring 8 length 200 ~ 250mm, pulling force 0.2 ~ 0.3mpa.
Slat conveyer runs, scraper plate fluctuating wobble skin, make whole with pendulum generation slightly swing, and the size of amplitude of fluctuation is passed to vertical shaft, vertical shaft vibrates, main shaft top is that an angle of 90 degrees welds an indicator scale, indicator scale amplitude of fluctuation size when normally running according to scraper plate, two side positions mounting limit master cock respectively above its free end, and be connected with switchgear building, when scraper plate there is cable chain, fall the abnormal operational conditions such as chain time, indicator scale reaches full swing position, position-limiting control switch effect, scraping transporter is out of service.Thus reach the effect of power-off protection.
This power-off protection apparatus has following economic benefit:
For 450 slat conveyers; when not installing power-off protector; the number of times that breaks down in year is about 8 ~ 10 times; flight chain damage rate is that 60%(whole scraper plate and chain material expense are about 20,000 yuan); scrape the probability that board motor (20,000 yuan of every platforms) burns out and be about 50%; primary fault about needs 3 hour repair time, and it is 520t that our factory raw coal hour enters the amount of the washing moon, and cleaned coal comprehensive yied is about 75%.
Can calculate 450 scraper plate years saving economic benefit is thus: (8 ~ 10) × ((2 × 60%+2 × 50%)+(500 × 75% × 600 × 3))=550 ~ 7,000,000 yuan.
Finally it should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted; although be described in detail with reference to the embodiment of the present invention; those of ordinary skill in the art is to be understood that; technical scheme of the present invention is modified or equivalent replacement; do not depart from the spirit and scope of technical scheme of the present invention, it all should be contained in claims of the present invention.
