A penstock for a face conveyor with a travel beam mounting socket

The subject of the invention is a gate of a longwall conveyor with a mounting socket for a travel beam connecting it with a mining powered support.

Hydraulic shifting devices belonging to the support are usually used to connect the face conveyor to the mine powered roof support.

In the known and commonly used solution, the end of the beam of the hydraulic shifter is connected to the fixing socket permanently attached to the valve support of the wall conveyor from the side opposite to the connection of the conveyor trough. The complicated shape of this seat is the result of the movement requirements of the powered support floor. The full profile of the clamping socket protrudes beyond the outer edge of the face conveyor valve. This is the main disadvantage of such a solution, as it prevents the complete shifting of the powered support section to the face conveyor, and, moreover, due to the complicated shape of the mounting socket of its position, it prevents the support from being firmly connected to the conveyor chute by means of bolted connections used for this purpose. Moreover, such a solution is material-consuming and complicates the construction of the face conveyor.

A device for coupling a mining support with a conveyor is also known from the Polish patent specification No. 64591. In this device, the shifter attached to the mechanized construction section is connected with its other end pivotally to the lower edge of the plate, the upper edge of which is also pivotally mounted to the wall of the conveyor valve. Such a construction allows for a variable contour of the conveyor from the side facing the housing during the movement of the mining housing section, but does not solve the problem of fixing the travel beam to the conveyor.

The aim of the invention is to eliminate the aforementioned disadvantages of the known solution of connecting the wall conveyor with a mining powered support, and in particular to allow the motorized support section to be fully moved to the edge of the valve of the wall conveyor, and to securely and simply screw the support to the chute of the wall conveyor. The invention also aims to simplify the structure of the wall conveyor and reduce its material consumption. These objectives were achieved by constructing a wall conveyor valve with a travel beam mounting seat.

The essence of the invention consists in the displacement of the mounting socket to the inner space of the wall conveyor support. An upper fixing hole is made in the upper, horizontal wall of the bracket. In the inner space of the support, above its base, a horizontal plate of the base of the socket is permanently fastened, in which the lower fixing hole is made coaxially with the upper fixing hole.

It is preferred that the upper wall of the support and the base plate of the socket are reinforced by permanently attaching the reinforcement caps around the upper and lower mounting holes thereto.

The subject of the invention is shown in the embodiment on the drawing, which shows the wall conveyor in a side section in the plane of the axis of the fastening socket of the travel beam.

Its construction is as follows. The conveyor chute 1 is connected on one side to the gripper 2, and on the other side to the side wall of the bracket 3. The upper fixing hole 4 is located in the upper, horizontal wall of the bracket 3. Above the base of the bracket 3, in its internal space, a horizontal plate is permanently mounted the base of the socket 5. In this plate, there is a lower fastening hole 6, placed on one vertical axis with the upper fastening hole 4. Around the upper fastening hole 4 and the lower fastening hole 6, reinforcing covers 7 are permanently mounted.

The bracket 3 constructed in this way is connected with the guide 8, forming a wall conveyor valve with the mounting seat of the travel beam. The end of the horizontally arranged travel beam is connected with the bracket 3 of the wall conveyor valve by means of a vertical pin inserted into the upper fastening hole 4 and the lower fastening hole 6. The supporting structure for such a connection consists of the structural elements of the bracket 3, in particular its upper horizontal wall and the base plate of the socket 5.

Claims (1)

Patent claim A gate of a wall conveyor with a mounting seat for a travel beam, consisting of a bracket to which the conveyor chute is connected with the groyne, and a guide, characterized in that the mounting seat is placed in the inner space of the support (3) of the wall conveyor so that in the upper on the horizontal wall of the bracket (3) there is an upper fixing hole (4), and coaxially with it, in the vertical axis there is the lower fixing hole (6), made in the horizontal plate of the socket base (5) permanently installed in the inner space of the bracket (3) above its base, it is preferred that reinforcing caps (7) are fixedly fixed around the upper fastening hole (4) and the lower fastening hole (6).
