Abstract
The utility model relates to an connecting ring on a coal mine exploitation feeding device, in particular to a connecting ring for the vertical ring of a conveyer. A connecting ring for the vertical ring of the conveyer is characterized in that the connecting ring consists of an upper half ring and a lower half ring which are matched through a steplike matching surface; one end of the steplike matching surface is provided with a located large arc tenon fossa the middle part of which is closed in a joint mode and is inserted with a unidirectional key; the other end is provided with a V-shaped surface used for assisting location; two elastic opened pins are connected with the connection location in a joint mode in the middle between the upper half ring and the lower half ring. The utility model has a unique structure, can be fast connected, is safe and reliable as well as has high intensity and reliability.
Description
Technical field
The utility model relates to the application coupling link on the pit mining load transfer device of a kind of colliery, especially relates to the upright articulating chain link of a kind of conveyer.
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 the curved tooth structure, is made up of two semi-rings and compound type locating dowel pin.The round-link chain chain ring that existing colliery pit mining load transfer device uses, adopted two semi-ring curved tooths to match and the compound type locating dowel pin, in use, the chain ring two ends are subjected to longitudinal pulling force, the compound type locating dowel pin is by the 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 compound type locating dowel 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 down-hole bad working environment, the stressed excessive chain annular strain that causes of chain, the compound type locating dowel pin often occurs and drop out chain link, cause chain link to damage, take off situations such as chain, chain rupture, increased the maintenance of equipment.Home and abroad colliery pit mining load transfer device speed of development is exceedingly fast in recent years, and the die is cast for the development of large-scale, heavy, superduty load transfer device, therefore this chain ring not only the life-span low, and poor reliability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, but a kind of structure uniqueness at high speed connection, safe and reliable a kind of novel high-strength, the upright articulating chain link of conveyer of high reliability are provided.
The utility model is realized in the following way
A kind of conveyer founds the articulating chain link, it is characterized in that: it is to be cooperated by stepped fitting surface by last semi-ring and following semi-ring to form;
One end of described stepped fitting surface is provided with great circle arc tenon nest, the sealing of middle part bridging type of location and is inserted with the unidirectional key, the other end that are used to locate and is provided with the V-type face that is used for auxiliary positioning;
Middle part bridging type sealing place is connected with two elastic opening pins between described upward semi-ring and the following semi-ring;
The described face that heals up of going up semi-ring and following semi-ring exceeds radius size in short transverse.
1) the structure uniqueness, prolonged service life: the conveyer that the utility model provides founds the articulating chain link, by two semi-rings and two elastic opening pins are formed up and down, round-link chain imposes on upright articulating chain link longitudinal force, inner great circle arc tenon nest locating surface in chain ring two ends and unidirectional key insert the location, reach the effect of transmitting pulling force, the chain link middle part is adopted and is taken key formula sealing piece design and two elastic opening pin designs, the opposing chain ring is out of shape tension up and down, improve the rupture strength of chain ring, avoid the chain knotting, the service life of improving chain ring.
2) fitting surface structure uniqueness: it is to be cooperated by stepped fitting surface by last semi-ring and following semi-ring to form for the utility model, and its height dimension approaches the flat round-link chain width dimensions of same specification much smaller than the flat articulating chain link of same specification width dimensions.
3) safe and reliable, range of use is wide: adopt the technical solution of the utility model, can effectively solve the stressed excessive chain annular strain that causes of chain, cause chain link to damage, take off chain, situations such as chain rupture, the opposing chain ring is out of shape tension up and down, improve the rupture strength of chain ring, avoid the chain knotting, increase the service life of chain ring, increase the reliability of chain ring, this chain ring is a kind of high strength, high reliability is found the articulating chain link, be applicable to long-term work large-scale in harsh environment more, heavy, on the pit mining load transfer device of high-power colliery, therefore, at high yield, using this structure chain ring on the load transfer device slat conveyer of efficient mechanical coal mining colliery can bring long-term for the colliery fully, considerable economic.

The specific embodiment
A kind of conveyer founds the articulating chain link, as shown in Figure 1, 2: it is to be cooperated by stepped fitting surface by last semi-ring 1 and following semi-ring 2 to form, one end of stepped fitting surface is provided with the great circle arc tenon nest 4 of location, the middle part bridging type seals and is inserted with the unidirectional key 5, the other end that are used to locate and is provided with the V-type face 6 that is used for auxiliary positioning as shown in Figure 3, middle part bridging type sealing place is connected with two elastic opening pins 3 between last semi-ring 1 and the following semi-ring 2, and the face that heals up of last semi-ring 1 and following semi-ring 2 exceeds radius size in short transverse.
Round-link chain is put into chain ring semi-ring appropriate location, the relative application of force of the vertical dislocation of semi-ring closes up and down, chain ring two ends great circle arc tenon nest 4 is located at this moment, the chain link middle part is taken the unidirectional key 5 of key formula and is also inserted the location thereupon, in two pin-and-holes, the elastic opening pin 3 of respectively packing into has promptly been realized the quick connection of round-link chain.
