Abstract

The present invention relates to coal mine conveying chain technology, and is especially one kind of compact conveying chain for scraper conveying machine to convey coal in narrow coal cutting work face and conveying tunnel in coal mine. Structurally, the compact conveying chain consists of several long horizontal welded rings and several long vertical forged rings connected alternately and is produced through welding, extending and heat treatment. The forged ring has rectangular cross section structure, the mechanical performance same as that of traditional ring with circular cross section structure but reduced outer width or height. The compact conveying chain has compact structure and prolonged service life.

Description

Compact type delivery chain

One, technical field;

The present invention relates to colliery delivery chain technical field, be used for that coal-face and belt heading transport the slat conveyer equipment delivery chain in colliery under the coal mine.A kind of specifically compact type delivery chain

Two, background technology:

Traditional mining face under mine transportation device colliery, colliery is to connect (through the welding back) with many identical oval ring establishments to become long annular chains form with the slat conveyer chain, power boosting along with transportation device, the also corresponding increase of its chain specification and transportation device oad, take bigger locus, cause mining face under mine operational space, colliery less also bad with effect of loading coal transportation device.

Three, summary of the invention:

In order to reduce the oad of colliery mining face under mine transportation device, reduce the height of transportation chute and equipment, alleviate transportation device weight, improve the effect of loading coal of transportation device, the invention provides a kind of compact type delivery chain, this chain has the mechanical characteristics of traditional annular chains.

The technical solution adopted for the present invention to solve the technical problems is:

Still adopt the oval ring of traditional circular cross section with the colliery with the oval ring of level of slat conveyer transportation device driving chain sprocket tooth mesh chain, adopt with the upright ring of the oval ring bonded assembly of level and forge long ring, the straight-arm that forges long ring partly adopts retangular section structure.The centre portion of upright ring arc section is a circular cross section, and circular cross section and rectangular cross section the transition phase partly section of the interior circular arc in the hexagonal angle scope are semicircle, in greater than the hexagonal angle scope by semicircle to the transition of round rectangle section.In the outside by circular cross section gradually to the transition of round rectangle section.The rectangular cross section area is 0.9～1.1 with the ratio of the circle cross section area of the oval ring of level.So the tensile strength of two rings is basic identical, this structure has reduced outer wide (highly) size of upright (length) ring, admittedly claim compact type delivery chain.According to varying in size of chain specification, upright (length) ring outer wide (highly) and the outer wide size of the oval ring of level to reduce ratio different (from little specifications greatly extremely) be 0.7～0.9.The oval ring structure of level is identical with the oval ring of traditional circular cross section.

The invention has the beneficial effects as follows:

Adopt the long ring structure compactness of forging of rectangular cross section, height and the weight of equipment of colliery can be reduced, the operational space under the narrow harsh environment under coal mine such as colliery slat conveyer transportation device, coal excavation apparatus and safety support equipment can be increased with slat conveyer transportation chute and equipment.Compact type delivery chain is compared with traditional circular cross section annular chains, has increased the area that the middle plate of chain and slat conveyer is in contact with one another, reduced chain and in the plate rate of wear, so increased the service life of chain and transportation device.

Five, the specific embodiment:

Embodiment 1:

From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 6 and Fig. 7 as can be known, compact type delivery chain is formed by upright ring (forging long ring) (1) and staggered successively establishment to the needs design length of the oval ring of level (2), finishes after welding (the oval ring of level), stretching, heat treatment.The ratio of upright ring among Fig. 1 (forging long ring) height dimension B and the outer wide size B1 of the oval ring of level is 0.7.Upright ring rectangular cross section area is 1.1 with the ratio of the circle cross section area of the oval ring of level.The centre portion of upright ring arc section is a circular cross section, the section of the interior circular arc in the hexagonal angle scope of arc section is a semicircle, in greater than the hexagonal angle scope by semicircle section to the transition of round rectangle section, the outside by circular cross section gradually to the transition of round rectangle section.

Embodiment 2:

From Fig. 1, Fig. 2, Fig. 3, Fig. 5, Fig. 6 and Fig. 7 as can be known, compact type delivery chain is formed by upright ring (forging long ring) (1) and staggered successively establishment to the needs design length of the oval ring of level (2), finishes after welding (the oval ring of level), stretching, heat treatment.The ratio of upright ring among Fig. 1 (forging long ring) height dimension B and the outer wide size B1 of the oval ring of level is 0.9.The centre portion of upright ring arc section is a circular cross section, the section of the interior circular arc in the hexagonal angle scope of arc section is a semicircle, in greater than the hexagonal angle scope by semicircle section to the transition of round rectangle section, the outside by circular cross section gradually to the transition of round rectangle section.
