Abstract
The utility model relates to a vertical-ring connector unit on high-power scraper conveying equipment for underground mining of coal mines, in particular to a novel vertical-ring connector unit which comprises an upper half ring (1), a lower half ring (2) and positioning pins (3). The upper half ring (1) and the lower half ring (2) are integrally connected with each other by the positioning pins (3). The novel vertical-ring connector unit is characterized in that two ends of the upper half ring (1) are respectively fittingly connected with two ends of the lower half ring (2) by mortise and tenon joints at the two ends of the upper half ring (1) and the two ends of the lower half ring (2), the middle of the upper half ring (1) is in lap joint with the middle of the lower half ring (2) in a concave-convex matching manner, pin holes are arranged at lap joints of the upper half ring (1) and the lower half ring (2), and the positioning pins (3) are mounted on the pin holes. According to the technical scheme, the novel vertical-ring connector unit has the advantages that problems of damage to an existing connector unit, chain releasing, chain breaking and the like due to deformation of the existing connector unit when stress on a chain is excessively high can be effectively solved, the connector unit can resist upper and lower deformation expansion force, the breaking strength of the connector unit is improved, chain knotting is prevented, the service life of the connector unit is prolonged, and the reliability of the connector unit is improved.
Description
Technical field
The utility model relates to the vertical ring chain ring on the high-power scraper plate load transfer device of colliery pit mining, especially a kind of novel vertical ring chain ring.
Background technology
At present, the connection of high-tensile round-link chain on the pit mining load transfer device of domestic colliery, the chain ring of employing is curved tooth structure (referring to accompanying drawing 1), is comprised of two semi-rings and Combined locating pin.The joint ring for chain that existing colliery pit mining load transfer device uses, adopted two semi-ring curved tooths to match and Combined locating pin, in use, the chain ring two ends are subjected to longitudinal pulling force, Combined locating pin is by interior mould-injection and the pin that rises, the location up and down semi-ring that curved tooth is cooperatively interacted is stressed, to reach the effect of transmitting pulling force.This curved tooth structure chain ring must strictly be controlled curved tooth size, angle and tolerance clearance, guarantees the expanding force of Combined locating pin and the breaking load of chain ring, just can reach the effect of transmitting pulling force.
Curved tooth structure chain ring is all very difficult in processing, measurement, and in actual use, because the abominable stressed excessive chain annular strain that causes of working environment, chain in down-hole, Combined locating pin often occurs and drop out chain link, cause chain link to damage, take off the situations such as chain, chain rupture, increased the maintenance of equipment.Recent domestic colliery pit mining load transfer device speed of development is exceedingly fast, and the die is cast for the development of large-scale, heavy, superduty load transfer device.So this chain ring life-span is low, and poor reliability has not been suitable for the development of load transfer device, for this situation, founds ring chain ring, the problem that exists to solve present chain ring in the urgent need to adopting new high-power slat conveyer.
The utility model content
The purpose of this utility model provides the novel vertical ring chain ring of a kind of high strength, high reliability, can realize quick connection and the safe and reliable use of colliery pit mining load transfer device high-tensile round-link chain.
A kind of novel vertical ring chain ring, form by upper semi-ring and lower semi-ring and with the locating dowel pin that both link into an integrated entity, its special feature is: the two ends of wherein going up semi-ring and lower semi-ring all are connected by the Tenon at this place, two ends, and the centre of upper semi-ring and lower semi-ring overlaps by concavo-convex cooperation, lap-joint on upper semi-ring and lower semi-ring all has pin-and-hole in addition, at pin-and-hole locating dowel pin is installed.
Wherein pin-and-hole has two, and locating dowel pin all is installed on each pin-and-hole, and locating dowel pin adopts the elastic opening pin.
Wherein be respectively equipped with tenon and mortise at upper semi-ring two ends, and be respectively equipped with corresponding mortise and tenon at lower semi-ring two ends.
Adopt the technical solution of the utility model, can effectively solve the stressed excessive chain ring distortion that causes of chain, cause chain ring to damage, take off the situations such as chain, chain rupture, the opposing chain ring is out of shape up and down tension, improve the rupture strength of chain ring, avoid the chain knotting, increase the service life of chain ring, increase the reliability of chain ring.Chain ring of the present utility model is the vertical ring chain ring of a kind of high strength, high reliability, be more applicable on large-scale, heavy, the high-power colliery pit mining load transfer device of long-term work in harsh environment, therefore, on the load transfer device slat conveyer of highly efficient and productive mechanical coal mining colliery, especially be fit to use the chain ring of this structure.

The specific embodiment
Shown in Fig. 2,3,4, the utility model is a kind of novel vertical ring chain ring, form by upper semi-ring 1 and lower semi-ring 2 and with the locating dowel pin 3 that both link into an integrated entity, the two ends of wherein going up semi-ring 1 and lower semi-ring 2 all are connected by the Tenon at this place, two ends, specifically be respectively equipped with tenon and mortise at upper semi-ring 1 two ends, and be respectively equipped with corresponding mortise and tenon at lower semi-ring 2 two ends.
And the centre of upper semi-ring 1 and lower semi-ring 2 overlaps by concavo-convex cooperation, specifically is provided with boss and groove in the centre of upper semi-ring 1, and is provided with corresponding groove and boss in the centre of lower semi-ring 2.Lap-joint on upper semi-ring 1 and lower semi-ring 2 all has pin-and-hole in addition, at pin-and-hole locating dowel pin 3 is installed.Specifically have two pin-and-holes, locating dowel pin 3 all is installed on each pin-and-hole, and locating dowel pin 3 adopts the elastic opening pin.
During use round-link chain is put into appropriate location on the semi-ring of chain ring, upper semi-ring 1 closes with the relative application of force of lower semi-ring 2 vertical dislocation, this moment, the great circle arc Tenon of its two ends band Self-locking angle was located, the chain link middle part is taken the unidirectional key of key formula and is also inserted the location thereupon, in two pin-and-holes, be respectively charged into the elastic opening pin, namely realized the quick connection of round-link chain.
