Abstract
A chain adapted to be driven over a horizontal pan, said chain including an oblong endless horizontal link, and an oblong endless vertical link, said vertical link having an overall height and said horizontal link having a horizontal width, said width to height ratio being greater than 1.3.
Description
Technical field
The present invention relates to be used to carry the transfer unit of the discrete material as coal and analogue, and relate more specifically to the chain that uses with the longwell delivery system incorporates.
Background technology
Fig. 1 has shown a part of longwell delivery system.Described delivery system comprises a drain pan and a coal transportation carrier bar mechanism thereon.The coal conveying mechanism comprises a chain sprocket driving device (not shown), and this device is along drain pan traction carrier bar mechanism.Fixed interval has scraper plate on chain.When chain and scraper plate when drain pan moves, by scraper plate coal is transported to the end of drain pan, at this place, coal is delivered to a mechanism that is used for taking out from underground mine coal.
The two kinds of different chain patterns that mainly contain with the use of longwell delivery system incorporates.A kind ofly be known as circular chain link or cross chain, and in Fig. 2, it be illustrated.In the cross chain, horizontal link chain has identical size with vertical chain.Another kind of chain is commonly called small-sized or flat link chain, and in Fig. 3 it is described.In a kind of flat link chain, used with the cross chain in identical horizontal link chain, but its vertical chain link is than the vertical chain link in the cross chain short about 1 ten five (15%).
Summary of the invention
The invention provides a kind of driven improved type chain above horizontal drain pan that is suitable for, described chain comprises a horizontal chain link and a vertical chain link, described vertical chain has overall height, and horizontal chain link has overall width, and the ratio of described and height-width is less than 2.In one embodiment, vertically chain link has non-circular " D " shape section, and the circular portion of described " D " shape part is towards the center of vertical chain link.In other embodiment (not shown), as be expected in the chain characteristic and occur and generation soon after chain uses, the profile phase coupling of the horizontal chain link that described special-shaped part is faced with it, thus between two chain links, finish in fact with the linearity contact.
Improved type chain of the present invention has produced several places and has improved, particularly when being applied to described chain in the longwell load transfer device.The wide plate chain is carried for longwell less chain height is provided.For thin seam mining, the final increase of power density allows to use lower linear drain pan, and for thicker seam mining, the geometric configuration of chain can reduce the wearing and tearing of chain and drive sprocket greatly.
Overall chain height reduce to be far smaller than flat link chain or cross chain, the result can reduce the overall height about 20 (20%) percent of conveyer drain pan.So just, can make the longwell conveyer above the conveyer drain pan, have bigger space and carry more coal.Lower drain pan height also allows to use the longwell conveyer at littler coal seam height.Shorter vertical chain link also allows to use lighter scraper plate, because overall height is less, therefore, for specified height, the required material of each piece scraper plate still less.
The horizontal chain link of the broad of chain allows the horizontal chain link of increase and drives area of contact between the sprocket wheel of horizontal chain link among the present invention.Fig. 2,3 and 5 have shown horizontal chain link ingear sprocket wheel a kind of and cross chain link or flat link chain.Fig. 4 and 6 has shown the of the present invention horizontal chain link by sprocket engagement.As illustrated in Figures 5 and 6, in fact among the present invention more horizontal chain link by sprocket engagement since this moment distribution of load in bigger zone, therefore can reduce to betide usually the abrasion loss in horizontal chain link and the sprocket wheel.
Vertically laterally long " D " shape section 13 of chain link can also be put forward other advantage.In fact, shown in Fig. 7 and 8, " D " shape section makes vertical chain link contact or pass the linear contact of whole surface formation of chain link with horizontal chain link at least two different contact point places.Can produce several advantages by this linear contact.By linearity contact, the wearing and tearing that can lower whole chain.When wearing and tearing took place chain, the expansion of chain wear can also reduce the elongation of chain.

Before describing one embodiment of the present of invention in detail, it is to be understood that the present invention should not be limited to limit or the structure of the parts of explanation and the details of layout in the accompanying drawings on it is used in following specification sheets.The present invention can have other embodiment and can realize in a different manner or finish.Equally, the purpose that it is to be understood that terminology used herein and term is explanation and should be considered limiting." comprise ", the use of " comprising " and distortion thereof means and comprises listed hereinafter article and its equivalent and other article." by ... constitute " and the use of distortion mean and only comprise listed hereinafter article and its equivalent.In addition, it will be appreciated that: be for convenience and the term that uses and should not constitute limited term as " forward ", " backward ", " left side ", " right side ", " making progress " and " downwards " etc.
The specific embodiment
As Fig. 4, shown in 6 and 7～10, the invention provides a kind of driven chain 10 above horizontal drain pan 14 that is suitable for, chain 10 comprises a horizontal chain link 18 and a vertical chain link 22, vertically chain link 22 has overall height, described horizontal chain link has overall width, and the ratio of described width and height is greater than 1.3.More particularly, vertically the width of chain link 22 is approximately 1.63 with the ratio of height, and shown in Fig. 7 and 8, vertically chain link 22 has " D " shape section, and the circular portion of described " D " is towards the center of the horizontal chain link 18 of Long Circle ring-type.
Fig. 9 has illustrated that how making a rod for example by welding its end be linked to each other forms the method for horizontal chain link 18.Figure 10 has illustrated in described most preferred embodiment, in the top of vertical chain link 22 and the method that base section is removed unnecessary excess stock.
To understand many other feature and advantage of the present invention from following claim.
