Abstract
An end casting (2, 4) for a conveyor line pan (1, 3) of the kind having two sigma side sections is of substantially constant thickness along its length and is provided with recesses (8, 14, 26, 28) on its outer face for the reception of a boltless connector (12). <IMAGE>
Description
IMPROVEMENTS IN OR RELATING TO CONVEYORS
This invention concerns improvements in or relating to conveyors of the kind known as armoured flexible conveyors utilised in the movement of bulk material especially in underground mines, for example coal mines.
The present invention has particular reference to end castings of the type described and claimed in our co-pending UK Patent
Application No 87 25F225 (Case 4868 & Wherein the thickness of the end casting section is substantially constant along its length thereby to improve durability. It is a requirement that the conveyor line pans, a series of which comprises the conveyor, are articulated one to the other to enable it to 'snake' within the seam when advancing the coal face. It is conventional to utilise bolted fittings which interengage the end castings for this purpose, and in the alternative to employ boltless fittings ocomonly known as 'dog bone' connectors.
It is an object of the present invention to provide an improved end casting for a conveyor line pan incoprorating a boltless connector.
According to the invention an end casting for a conveyor line pan of the kind having two sigma side sections interconnected centrally by a deck plate over which chain driven flight bars are arranged to be driven, the end casting being of substantially constant thickness along its length, wherein the end- casting is provided on its relatively outer face with recesses to accommodate and retain the shank and the head of a boltless connector.
The recesses are formed centrally of the end casting with one extending longitudinally for the shank and the other opening out therefrom to receive in retaining manner the head of the connector. In this respect, the relatively larger recess is provided with retaining lugs behind which the head of the connector engages.
The recess for receiving the shank of the connector may taper longitudinally in order to afford some clearance for the purpose of flexibility in use.
By way of example only one form of end casting according to the invention is described below with reference to the accompanying drawings in whi: Figure 1 is a side view of two interengaging
end castings secured to the end of adjacent
line pans;
Figure 2 is a perspective exploded view of two
mating end castings; and
Figure 3 is a side view of a boltless connector.
Referring to the drawings, line pans 1, 3 eadh has an end casting of male and female form shown in Figures 1 and 2 respectively at 2 and 4 being of substantially constant thickness along their length. The male end casting 2 has a projection 6 formed centrally thereof and this is provided with a longitudinally tapering recess ss 8 to accommodate the shank 10 of a boltless connector 12.
The recess 8 opens into a further and larger recess 14 which in use- accommcdates a head 16 of the connector and a fixing element 18 thereof. Retaining lugs 20 are formed on part of the peripheral edges of the recess 14 for engaging the fixing element 18.
The projection 6, in use, registers within a reception area 22 on the female end casting 4 which has a boss 24 provided with a longitudinally extending recess 26 for receiving the shank 10 of the connector 12 as shown in ghosted outline in Figure 1. The recess 26 opens into a further recess 28 for receiving and retaining a head 30 of the connector 12. Retaining lugs 32 are provided at the peripheral edges of the recess 28 for engaging the head 30.
In Figure 1, the connector 12 is shown in situ with the shank 10 in the recesses 8 and 26 of the male and female end castings 2,4 and the heads 16, 30 of the connector occupying the recesses 14, 28, the head 30 being retained behind the lugs 32. As seen from Figure 3, the head 16 of the connector 12 has an end extension 40 over which the fixing element 18 is intended to slide, the element being retained behind the lugs 20. The end extension preferably has a cross hole 42 for a retaining pin (not shown).
Application of the connector 12 is achieved from the female end casting by first inserting the head 30 and the shank 10 into the respective recesses and then locating the head 16 in the recess 14, the fixing element 18 being slid over the end extension 40 behind lugs 20 with a pin inserted in the cross hole 42.
The present invention combines the strength and enhanced wear characteristics of our earlier invention with the ease of pan assembly afforded by utilising a boltless connector.
Claims (5)
1. An end casting for a conveyor line pan of the kind having two sigma side sections interconnected centrally by a deck plate over which chain driven flight bars are arranged to be driven, the end casting being of substantially constant thickness along its length, wherein the end casting is provided on its relatively outer face with recesses to accommodate and retain the shank and the head of a boltless connector.
2. An end casting as claimed in claim 1 in which recesses are formed centrally of the end casting with one extending longitudinally for the shank and the other opening out therefrom to receive in retaining manner the head of the connector.
3-. An end casting as claimed in claim 2 in which the relatively larger recess is provided with retaining lugs behind which the head of the connector engages.
4. An end casting as claimed in claim 2 in which the recess for the shank of the bolt tapers.
5. An end casting substantially as hereinbefore described with reference to Figures 1, 2 and 3 of the accompanying drawings.
