Description
Technical field
The utility model belongs to the safe handling facilities in a kind of coal mine tunnel initating, construction of tunnel, metal, the nonmetallic ore construction, relates in particular to scraper mucking.
Background technology
At present, mainly there is the following aspects problem in scraper mucking in actual use in security protection:
1, according to " safety regulations in coal mine " regulation, scraper mucking must be furnished with full section safety device.And actual in the production of scraper mucking, do not embody this point, existing national neither one manufacturer production has the scraper mucking of full section safety device.
2, in use, in order to reach the requirement of " safety regulations in coal mine ", applying unit generally is to make according to the actual conditions in tunnel.But because the tunnel has height to become a series of situations such as slope, Gao Maoqu.In zones such as Gao Maoqu, the safety device of making generally all can not be used, and other zones are adjusted frequent.
3, all now safety device is used Bolt Connection after all being based on the top angle bar, boring of scraper mucking chute.Because chute is yielding, last angle bar limit intensity is low, fragile.So under the on top impaired situation, the tipping bucket accident takes place, can not play the security protection effect.Security reliability is poor.
4, full section security protection should comprise chute directive wheel front region, and this part is a blank, owing to there is not reliable security protection, cause in the 12m scope of rules regulation directive wheel rear, when the slusher machine operation, must not carry out the parallel operations of other work, this has limited digging efficient significantly, up to more than 15%.
When 5, moving scraper mucking, modal wire rope suspensioning formula protector will whenever move a scraper mucking and make a call to four anchor poles and fix, and is not only time-consuming, also will spend about 300 yuan cost of materials, 200 yuan of labour costs etc. at every turn.Move once by every 30m, developing in general year 3000m in big-and-middle colliery will move 100 times, will waste 50,000 yuan.The in-situ processing protector is very time-consuming, also is a factor that influences scraper mucking efficient, approximately influences about 8% according to measuring and calculating.Be converted into output value separate unit be about 420,000 yuan/month promptly the annual only this item of big-and-middle-sized mine can lose up to more than 5,000,000.
6, because chute often damages, and the chute interchangeability of different manufacturers has certain problem, after changing chute, the protector of making before also usually using does not connect, and make again.And the protector reusability of field fabrication is poor.It is too big to compare the fixing safety device input that can roll over dress.
7, former also production of the producer that has fixed or safety device.But only in the intermediate channel part of chute.And fail to realize " full section " security protection.And because mill slusher machine wire rope.When chute is out of shape, poor practicability is not installed.Be eliminated one after another.Promptly up till now, also there is not a kind of reliable comprehensive security protector.
Summary of the invention
In order to solve the problem that existing scraper mucking lacks full section security protection, the utility model provides a kind of scraper mucking with full section security protection mechanism.
The technical solution that realizes above-mentioned purpose is as follows:
Scraper mucking with full section security protection mechanism comprises the directive wheel, dumping apron, middle part chute and the dustpan mouth that connect successively, and the below of middle part chute is provided with motor, reductor and cylinder;
Described dumping apron both sides are respectively equipped with preposition protective guard, the corresponding linkage section with dumping apron of chute both sides, described middle part are respectively equipped with intermediate channel epimere protective guard, described middle part chute is respectively equipped with intermediate channel hypomere protective guard with the corresponding linkage section of dustpan mouth both sides, and described dumping apron inlet portion both sides are connecting web beam between the preposition protective guard top.
The inlet portion both sides of described dumping apron inlet portion and export department both sides, described middle part chute middle part and export department both sides and described dustpan mouth are respectively equipped with the protective guard seat;
Described preposition protective guard, intermediate channel epimere protective guard and intermediate channel hypomere protective guard comprise two vertical rods and the cross bar more than respectively, and connect to form frame-like, and the vertical rod lower end is plugged in the protective guard seat;
Connecting web beam between the vertical rod top of the preposition protective guard in described dumping apron inlet portion both sides.
Described protective guard seat is a L type channel-section steel, and its long limit is connecting portion of the group outside of dumping apron or middle part chute or dustpan mouth, and minor face is connecting dumping apron or middle part chute or dustpan mouth bottom outside; Described vertical rod and cross bar are channel-section steel; Described vertical rod lower end and protective guard seat splicing position are provided with stiffener.
The height of described intermediate channel epimere protective guard and intermediate channel hypomere protective guard is the 300-500 millimeter.
Useful technique effect of the present utility model is embodied in the following aspects:
1, preposition safety guide rail of the present utility model, can prevent to rout up when slusher from moving in the mistake position chute effectively reliably, because the intensity of channel-section steel is much larger than the intensity of wire rope, the upper beam of inclined design is after wire rope is disrumpent feelings, and slusher is stuck under motorless situation; Hurt sb.'s feelings thereby prevented from effectively to turn over before the slusher.Play the security protection effect.
2, spron side rail of the present utility model mainly plays the effect of the both sides of dumping apron being carried out security protection; Prevent the accident that slusher forms in this section rollover.This section is made by single channel-section steel, makes simply easy accessibility.
3, intermediate channel epimere protective guard of the present utility model mainly plays the effect of slusher in this section rollover that prevent to the middle part epimere.With the intermediate channel sectional making.Plug-in type connects, the coupling reliability height, and the middle part does not have upper beam, can not form the wearing and tearing to the operation wire rope.Channel-section steel assembly welding intensity height, anti-accident ability is strong.
4, the utility model intermediate channel hypomere protective guard, this section are the emphasis of comprehensive security protection, are one of operating positions of slusher machine driver.Based on the both sides plug-in type protective guard of the anti-beam base of L type, intensity height, good reliability.
In sum, the utility model design science is reasonable, and intensity is big, reliability is high, adopts detachable plug in construction design, is convenient to assembling and disassembling and transportation, can move at random; Do not need to beat and hang gown and fix, the efficient height is real comprehensive security protector.
