CN201087009Y - Side removing type chain ring for compact chain vertical ring for mining - Google Patents

Abstract

The utility model relates to a side tipping type mine connecting link for a compact chain vertical ring. The utility model is a special conveyor chain, a coupling device between the Compact chain sections occurring in the coalmine machinery in recent years. Because the outer side of the utility model is wide, the dimension is small, and the utility model is different from a standard connecting link. The utility model adopts a wear part, the majority of connecting links are invalid due to the damage of the connecting part during the using process. The utility model adopts the technology key point that the strength of the coupling part of the connecting link and the connecting reliability can be strengthened. The connecting link is composed of three parts, and two large-semicircular holes and three T-shaped tongue-and-grooves with backward locking oblique angles are arranged on a large semi ring. The two small-semicircular holes and the three Tshaped tongue-and-grooves with backward locking oblique angles are arranged on a small semi ring., when being connected, the flat rings at the end heads of two chain sections are respectively put into two semi-circulars of the large semi ring firstly, and then the small semi ring is buckled from side direction. After T-shaped rabbets are fully added in the tongue-and-grooves, a spring pin is added. When the chain segment is loaded, the two semicircular T-shaped rabbets can be tightly locked due to the backward locking oblique angles, the damage is not caused due to pulling off the tongue-and-grooves.

Description

Side dump is mining compact vertical chain ring chain ring

Affiliated technical field: the utility model relates to the new-type conveyer chain-compact chain in a kind of coal mine machinery, the connecting device between the segment, and only be used for upright ring.

Background technology: compact chain is emerging in the world in recent years mining conveyer chain, and its feature is that the outer wide size of upright ring is little, can not connect with governing criterion chain ring in the MT/T99-1997 industry standard.Only met the trivial formula chain ring of a kind of V in the market.The vertical dismounting of the trivial formula chain ring of V, two semi-rings equally connect with two T type tenons.

Chain ring is easily to change part, and its inefficacy mainly is because the fracture damage at link position.The key points in design of institute's chain ring is under enabled condition, increases the intensity and the coupling reliability of point of attachment as far as possible.

Summary of the invention: under enabled condition, strengthen the intensity of chain ring point of attachment and the reliability of connection is the technical problem underlying that need solve when designing chain ring as far as possible.

The utility model is for solving the technical scheme of its technical matters: adopt the side direction dismounting, connect with three type tenons, open support for preventing that T type tenon is past behind load, adopted and can fall trivial structure.

The utility model is a chain ring, by big semi-ring, small semi-ring, three compositions of spring Xiao are put into the flat ring of two segment ends respectively earlier two semicircle holes of big semi-ring during chain link, buckle small semi-ring again after, at the middle part of chain ring, laterally squeezed into spring Xiao, two segments have just been caught.

The beneficial effects of the utility model are that the side direction dismounting can be added a T type tenon, and T type tenon can both be trivial, can hold tightly when carrying, have increased the linking intensity of chain ring and the reliability of connection, prolong its service life with the breakage that delays point of attachment.

Description of drawings: the utility model is further specified below in conjunction with accompanying drawing:

Fig. 1 is the trivial chain ring of V-type that present mining compact vertical chain ring is used.

Fig. 2 is that its A-A cuts open figure.

Fig. 3 is that its B-B cuts open figure.

Fig. 4 is a constructional drawing of the present utility model.

Fig. 5 is that utility model T type tenon falls the enlarged drawing of trivial structure.

Fig. 6 is spring Xiao's occupation mode figure.

The utility model is made up of (3) three of big semi-ring (1) small semi-ring (2) spring Xiao in Fig. 4.

The specific embodiment: the holes of circle and three bands fall the T type tongue-and-groove at trivial oblique angle mostly two in Fig. 4 on the big semi-ring (1).Small semi-ring (2) has the hole of two not a half circles and three bands to fall the T type tenon at trivial oblique angle, during connection, earlier with the flat ring in the termination of two segments, puts into two semicircles of big semi-ring respectively, buckles small semi-ring from side direction again.After buckling into tongue-and-groove fully Deng T type tenon, squeeze into spring Xiao (3), two segments just have been connected together.When the segment load, the T type tenon of two semi-rings is embraced tighter and tighter because of the oblique angle of locking in is arranged, and is not damaged because of strutting tongue-and-groove.
