Description
Technical field
A kind of extension band type conveyor E type pin of the utility model, belongs to conveyor technical field.
Background technique
In underground coal mine working face plane system, extension band type conveyor plays an important role, and the raw coal being responsible for working surface production to get off continuously is transported in the main conveying system of down-hole.Along with the quick propelling of working surface, extension band type conveyor tail must follow up in time, so just requires that its fuselage can meet fast assembling-disassembling.
E type pin is central link part in extension band type conveyor fuselage, is responsible for middle frame and middle frame, upper supporting roller frame and middle frame and the connection between supporting leg and middle frame, can meets fuselage and realize fast assembling-disassembling.Its catenation principle be utilize E type pin resiliently deformable produce the connection that extruding force realizes between connected piece.According to existing E type pin service condition, because equipment is in the continuous vibrations of running middle machine body, E type pin is easy to come off.
According to the structure of existing E type pin, increase its subtended angle though simple and can increase connection elastic force, also correspondingly increase the opening size of plug, increase the difficulty of installing.Therefore, be necessary to be improved.
Model utility content
In order to overcome the deficiencies in the prior art, provide that a kind of structure is simple, easy installation and removal, the reliable a kind of E type pin of safety and stability.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of extension band type conveyor E type pin, comprise latch and plug, there is plug latch one end, and the angle between described latch is 7 ° ~ 9 °.
Described plug is tilted conical.
The taper of described tilted conical is tilted to the inside.
Angle between described latch is 8 °.
Round-corner transition is adopted between described latch and plug.
The beneficial effect that the utility model is compared with prior art had is:
1, two latch subtended angles are larger, and resilient pressing force is sufficient, makes to be interconnected more reliably fastening;
2, adopt novel plug, ensure when enough subtended angles, make latch opening minimum, reliable and stable, easy for installation.
Accompanying drawing explanation
Below by accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is plan view of the present utility model;
Fig. 2 is left view of the present utility model;
In figure, 1 is that latch, 2 is for plug.
Embodiment
The utility model will be further described by reference to the accompanying drawings for embodiment below.
As depicted in figs. 1 and 2, a kind of extension band type conveyor E type pin, comprise latch 1 and plug 2, there is plug 2 latch 1 one end, and the angle between described latch 1 is 7 ° ~ 9 °.
Described plug 2 is tilted conical.
The taper of described tilted conical is tilted to the inside.
Angle between described latch 1 is 8 °.
Round-corner transition is adopted between described latch 1 and plug 2.
Increase the angle between two latches 1, resilient pressing force is sufficient, makes to be interconnected more reliably fastening; New plug 2 adopts tilted conical structure, and taper is tilted inside E type pin, and at utmost reduce the opening of E type pin, cone structure and upper square-round steels coupled position use round-corner transition.New structure has sufficient elastic force, and less opening, greatly increases the reliability of connection, and largely reduce installation difficulty.
Claims (3)
