专利汇可以提供Mineral mining installations专利检索，专利查询，专利分析的服务。并且A mineral mining installation composed of a conveyor with a guide member for a plough on one side. The position of the guide member in relation to the floor of a mine working is controlled by means of beams connected to the goaf side of the conveyor. In one construction each beam is pivotably connected to the arms of a U-shaped bracket connected to the conveyor and a locking pin is insertable into various alignable bores in the beam and the arms of the bracket in order to secure the beam in various angular positions. In another construction each beam is composed of a channel member rigidly affixed to a leaf spring. The channel member is connected in the manner of a toggle linkage with a plate affixed to the goaf side of the conveyor and a piston and cylinder unit is connected between the channel member and the plate to effect a change in angular position.，下面是Mineral mining installations专利的具体信息内容。
1. In or for a mineral mining installation having a guide member attached to one side of a conveyor, an arragement for controlling the position of the guide member; said arrangement comprising an elongated beam with an end remote form the conveyor raisable and lowerable to effect such control and means for selectively connecting the beam to the conveyor in various angular control positions.
2. An arrangement according to claim 1, wherein the beam is connected to a bracket disposed on the side of the conveyor remote from the guide member.
3. An arrangement according to claim 2, wherein the bracket is U-shaped and there is provided means for pivotably connecting the beam to the bracket.
4. An arrangement according to claim 2, wherein the bracket is U-shaped, the arms of the bracket and the beam having alignable bores therein and wherein the selective connecting means is a locking pin insertable into various alignable bores in the beam and the arms of the bracket.
5. An arrangement according to claim 2, wherein there is provided means for connecting the bracket to the conveyor so as to permit the bracket to move to a limited extent in the direction of the longitudinal axis of the conveyor.
6. An arrangement according to claim 1, wherein the selective connecting means serves to connect the beam to the conveyor in one of several pre-determined angular positions.
7. An arrangement according to claim 6, wherein there are three said pre-determined angular positions.
8. A mineral mining installation comprising a. a conveyor: b. a guide member attached to the mineral face side of the conveyor; c. a plurality of beams disposed on the side of the conveyor remote from the guide member; d. U-shaped brackets connected to the side of the conveyor remote from the guide member, the arms of each bracket receiving an end portion of one of the beams therebetween; e. bores in the end portions of the beam and in the arms of the brackets; f. a pivot pin inserted into aligned bores in the arms of each bracket and the end portion of the associated beam to render the beam pivotable in relation to the bracket; and g. a locking pin insertably into alignable bores in the arms of each bracket and in the end portion of the associated beam to secure the beam in one of several pre-determined angular positions.
9. In or for a mineral mining installation having a guide member attached to one side of a conveyor an arrangement for controlling the position of the guide member; said arrangement comprising an elongate beam, a plate extending from the side of the conveyor remote from said one side, means for pivotably connecting the beam to the plate and a generally upstanding piston and cylinder unit for effecting relative displacement between said plate and the beam in the manner of a toggle linkage to thereby control the position of the guide member.
10. An arrangement according to claim 9 wherein the beam is composed of a channel member receiving the plate and a leaf spring affixed to the end of the channel member remote from said plate.
11. In or for a mineral mining installation having a guide member attached to one side of a conveyor, an arrangement for controlling the position of the guide member; said arrangement comprising an elongate beam, a U-shaped bracket disposed on the side of the conveyor remote from the guide member, a pivot pin connecting the beam to the bracket, alignable bores in the arms of the bracket and the beam and a locking pin insertable into aligned bores of the beam and the arms of the bracket to thereby connect the beam to the conveyor in one of several angular control positions.
12. A mineral mining installation comprising: a. a conveyor; b. a guide member attached to the mineral face side of the conveyor; c. at least one plate at the side of the conveyor remote from the guide member; d. an elongate beam disposed at the side of the conveyor remote from the guide member; e. means for pivotably connecting the beam to the plate; and f. a generally upstanding piston and cylinder unit operably connected between the plate and the beam to thereby effect relative displacement between said plate and said beam in the manner of a toggle linkage to control the position of the guide member.
13. An installation according to claim 12, wherein the beam is in the form of a channel member receiving the plate and a leaf spring affixed to the end of the channel member remote from the plate.
14. An installation according to claim 13, wherein said leaf spring is connected to a drag prop.
15. An installation according to claim 12, wherein a plough is guided for movement along the guide member, there being further provided a linkage connected to the plough and extending over the conveyor and a slidable guide locating the lInkage on a rail at the side of the conveyor remote form the guide member.
