Description

The two guiding of center strand slat conveyer scraper plate

Technical field:

The utility model belongs to the coal mining field of transport machinery, relates to the scraper plate of a kind of center strand slat conveyer (containing elevating conveyor), particularly a kind of two guiding scraper plates.

Background technology:

It is that forward folk prescription is only made the short range backwards rotation to conveying when chain link or tight chain that center strand slat conveyer (containing elevating conveyor) under the coal mine is in operation always.Because existing coal mine lower scraping plate conveyer can not two-wayly be carried, the needed a large amount of materials of driving surface are always entirely by artificial heavy difficult ground conveyance, not only labor strength is big, efficient is low, influence is produced, and running counter to the common function of the two-way conveying of Transport Machinery, the needs that more and more incompatible modern coal borehole operation is produced are demanded urgently improving.

Scraper plate in slat conveyer, for chain link plays directional tagging, and scraper plate by two chute interfaces when the mismatch amount exceeds standard, self also need the guiding.Though former slat conveyer design has considered and the gauge of mismatch up and down of two chutes has been fixed in the 2mm this point that left and right sides mismatch gauge fixes in the 3mm, should be unblocked at this ideal state lower scraping plate.But in the rugged environment, chute mismatch amount often substantially exceeds regulation under coal mine, will inevitably influence the unobstructed property of scraper plate at the chute interface, and the scraper plate card phenomenon of stumbling often takes place.Scraper plate is in case stumbled, and is difficult to suitablely to lead, and gently then the conveyer operation has some setbacks, and heavy then scraper plate is stumbled disconnected, stumbles, if in the kerve that drops, other scraper plate of can stumbling again causes conveyer to hinder dead accident, and it is big to deal with difficulty, the time-consuming ordinary production that has a strong impact on of expense.

The designer is after hearing that being engaged in the first-line workman of colliery underground mining hauling operation reflects the existing above-mentioned defective of existing slat conveyer, through investigation and analysis, think: the major cause that causes above-mentioned present situation be the shape at the scraper plate of existing slat conveyer and the both ends that the chute inboard is close improper due to.(select from " the coal industry standard MT//152-1997 of the People's Republic of China (PRC) ") as shown in Figure 2, the plan view shape at the both ends that are close with the chute inboard of existing scraper plate is an arc Eight characters shape, be that the both ends of the surface plan view shape is an arc, being Eight characters shape distributes, arc distance is forward narrower, reverse broad causes conveyer unidirectionally to carry, and can not long-time reverse running; When scraper plate when exceeding standard by two chute interface mismatch amounts, guiding changes, scraper plate stumbled be difficult to lead behind the card suitable, along with the scraper plate operation card of stumbling is more and more serious, the scraper plate of stumbling that breaks of consequently stumbling.

The utility model content:

The designer is through above-mentioned analysis and on-the-spot experience, be determined is that Coal Production and workman's work are considered, purpose is to develop a kind of scraper plate that can overcome the existing above-mentioned critical defect of existing slat conveyer (containing elevating conveyor), to give full play to the effect of existing slat conveyer.

Technical solution adopted in the utility model is, shape to existing center strand slat conveyer scraper plate is improved, design the two guiding of a kind of center strand slat conveyer scraper plate, its planform is: scrape plate body, the scraper plate both ends that are close with the chute inboard, wherein the scraper plate both ends plan view shape that is close with the chute inboard is that symmetrical arc is trapezoidal, it is trapezoidal to be that both ends all are, with the inboard directly approaching trapezoidal upper base of chute, curved, be used to realize the two-way transportation of slat conveyer and play easily the stumbled effect of card of scraper plate that solves.

Because the utility model takes abovementioned technology that the shape of existing slat conveyer scraper plate is improved, at first since change into trapezoidal, so scraper plate just can be in chute way traffic, thereby realized the two-way conveying of slat conveyer; Because trapezoidal upper base (outside) is short arc, thus when scraper plate in case stumbled, can be very fast it is unobstructed can not to influence conveyer along logical, the scraper plate bad resistance machine accident of stumbling more can not take place.

This two guiding scraper plates of the present utility model only improve a little to the shape of existing scraper plate, just can solve the existing problem of existing slat conveyer fully preferably, realized the two-way conveying of slat conveyer (containing elevating conveyor), for slat conveyer has increased new function, improved capacity utilization rate, reduced underground labour's heavy hard working, reduce downhole materials and transported cost, improved work efficiency, avoided the mechanical accident generation preferably, and transformed simply, be easy to promote, no development risk has significant advantage and positive effect.

Description of drawings:

Fig. 1 represents the planform scheme drawing of the two guiding of the utility model center strand slat conveyer scraper plate;

Fig. 2 represents existing center strand slat conveyer blade structure scheme drawing.

The specific embodiment:

In conjunction with the accompanying drawings and embodiments, further specify concrete structure shape of the present utility model.

The embodiment 1 of the two guiding of the utility model center strand slat conveyer scraper plate, referring to Fig. 1, expression is to the improvement of existing U-bolt formula scraper plate, its structure comprises: scrape plate body 1, with the chute inboard near end 4.1,4.2, fixed orifice 3, key way 2, be that symmetrical arc is trapezoidal with the chute inboard near the plan view shape of end 4.1,4.2 wherein, promptly both ends all are trapezoidal, be short arc with the inboard directly approaching trapezoidal upper base 5.1,5.2 of chute.

Embodiment 2 of the present utility model is a kind of to existing improvement of pressing chain scraper, and its structure comprises existing structure of pressing chain scraper, and wherein the plan view shape with the inboard approach end of chute is identical with embodiment 1, and it is trapezoidal to be symmetrical arc.

Unobstructed in order to ensure slat conveyer safety in two-way conveying, except that adopting the measure of described two guiding scraper plate, also the amount of mismatch up and down of two chute interfaces is expanded in the 11mm, left and right sides mismatch amount expands in the 19mm.

This two guiding scraper plates of the present utility model also are applicable to elevating conveyor.
