Description

A self-moving tail roller multi-directional adjustment device for belt conveyors

technical field

The utility model relates to the technical field of a multi-directional adjustment device for self-moving tail of a retractable belt conveyor used in coal mines, in particular to a multi-directional adjustment device for idlers with self-moving tail of a belt conveyor, which is used in coal mines It is used in conjunction with the trough transfer machine to undertake the coal unloaded by the transfer machine.

Background technique

There are many self-moving devices for the tail of the retractable belt conveyor in the traditional underground coal mine, and they are basically designed for the reloader and the retractable belt conveyor with specific supporting dimensions, which have poor adaptability and no adjustability. Therefore, belt conveyors with different unloading heights require different matching heights for the tail self-moving device. Otherwise, the height difference will adversely affect the operation of the belt, damage the belt, reduce the life of the belt and seriously affect the unloading effect, causing the raw coal to overflow and fall onto the lower belt. If belt conveyors of different heights are equipped with self-moving devices of different heights, the cost is high and the utilization rate of the equipment is low.

Contents of the invention

The purpose of the utility model is to provide a multi-directional adjustment device for the idler roller of the belt conveyor tail self-moving, which can overcome the problems of the existing retractable belt conveyor tail self-moving device that cannot be interchanged and has poor adaptability.

The technical scheme adopted in the utility model is: the multi-directional adjustment device for the self-moving idler of the machine tail is composed of an adjustment frame, an idler frame, a quadrilateral connecting rod mechanism, a telescopic hydraulic cylinder and a slider, and a height adjustment hydraulic cylinder. The upper hinged end is connected with the upper hinged end of the head end frame, and the lower hinged end of the adjustment device is connected with the lower hinged end of the head end frame through the height adjustment hydraulic cylinder; the quadrilateral linkage mechanism and telescopic hydraulic cylinder and slider, height adjustment hydraulic cylinder All are installed on the adjustment frame, wherein the second hinge center of the quadrilateral linkage mechanism is fixed on the adjustment frame, and the first hinge center of the quadrilateral linkage mechanism is connected with the telescopic hydraulic cylinder and the slider installed on the adjustment frame; The roller frame is fixed on the quadrilateral linkage mechanism by the pin shaft, and the roller brackets are connected in turn through the guide rod. Under the action of the telescopic hydraulic cylinder, the quadrilateral connecting rod mechanism is deformed, and the adjacent idlers are uniformly elongated along the telescopic direction of the telescopic hydraulic cylinder, and the total elongation distance is a multiple of the stroke of the telescopic hydraulic cylinder.

The beneficial effect of the utility model is that the height and length of the butt joint section can be adjusted at any time according to the working conditions, which greatly improves the interchangeability and adaptability. The structure is reasonable, the operation is convenient, the economy is applicable, and it is suitable for the narrow and harsh environment of the underground coal mine.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model,

The double dotted line part in the figure is a schematic diagram of the adjustment action that can be adjusted in both the docking height and the docking length with the belt conveyor.

Detailed ways

In the figure: 1. idler frame, 2. quadrilateral linkage mechanism, 3. slide block, 4. adjustment frame, 5. telescopic hydraulic cylinder, 6. height adjustment hydraulic cylinder, 7. upper hinged end of head end frame, 8 . the lower hinged end of the head end frame, 9. the head end frame, 10. the guide rod.

It can be seen from the figure that the multi-directional adjustment device for the self-moving idler roller of the tape machine is composed of an adjustment frame 4, an idler frame 1, a quadrilateral linkage mechanism 2, a telescopic hydraulic cylinder 5, a slider 3, and a height adjustment hydraulic cylinder 6. , the upper hinge end of the adjustment frame 4 is connected with the upper hinge end 7 of the head end frame 9, the lower hinge end 8 of the adjustment frame 4 is connected with the lower hinge end 8 of the head end frame 9 through the height adjustment hydraulic cylinder 6, and the quadrilateral linkage mechanism 2, the telescopic hydraulic cylinder 5, the slider 3, and the height-adjusting hydraulic cylinder 6 are all installed on the adjustment frame 4, the second hinge center of the quadrilateral linkage mechanism 2 is fixed on the adjustment bracket 4, and the first joint of the quadrilateral linkage mechanism 2 The first hinge center is connected with the telescopic hydraulic cylinder 5 and the slider 3 installed on the adjustment frame 4. The roller frame 1 is fixed on the quadrilateral linkage mechanism 2 by the pin shaft, and the roller frames 1 are connected in turn through the guide rod 10. , the quadrilateral linkage mechanism 2 is sequentially assembled from movable linkages, and is fixed on the hinge center with a pin shaft. The telescopic direction of the cylinder 5 is uniformly elongated, and the total distance of the elongation is a multiple of the stroke of the telescopic hydraulic cylinder 5 . When in use, according to the needs of the site, the length is first adjusted to a suitable length through the telescopic hydraulic cylinder 5, and then the height is adjusted to a suitable height through the height adjustment hydraulic cylinder 6.
