Description

Technical Field

[0001] The utility model belongs to the technical field of conveyors, and specifically relates to a double-adjustable push beam for a scraper conveyor. Background Technique

[0002] During the production process of a coal mine working face, due to the change in the length of the working face, it is necessary to change the length of the scraper conveyor to adapt to the change in the working face length. At this time, it is necessary to add or remove adjustment grooves. After adding or removing the adjustment grooves, the connection position between the scraper conveyor and the hydraulic support will change. If the connection position between the scraper conveyor and the hydraulic support cannot be changed in time, there will be a situation where the roof of the coal mining working face is not supported, which is what is usually referred to as empty roof, and empty roof is a safety hazard that is not allowed.

[0003] To solve the problem of empty roof, the current common practice in the industry is to replace the appropriate push beam.

[0004] However, there are two problems in this regard:

[0005] First, the operation space in the coal mine underground working face is small, and there is no suitable lifting equipment, so replacing the push beam is time-consuming and laborious.

[0006] Second, since there are many types of lengths of the adjustment grooves in the working face, it is necessary to design push beams of different specifications, and the production and manufacturing costs are relatively high. Summary of the Invention

[0007] The technical problem to be solved by the utility model is: how to design an adjustable push beam for connecting a scraper conveyor and a hydraulic support in a fully-mechanized coal mining working face underground in a coal mine.

[0008] To achieve the above technical objectives, the utility model adopts the following technical solutions:

[0009] A double-adjustable push beam for a scraper conveyor, comprising a push beam body, a pin shaft, a washer, an open pin, and a row-hole movable support frame body; wherein, the row-hole movable support frame body is installed on the push beam body, the row-hole movable support frame body is connected to the push beam body through the pin shaft, and the pin shaft is fixed with the washer and the open pin.

[0010] Preferably, the row-hole movable support frame body is adjusted at multiple horizontal positions on the push beam body.

[0011] The utility model discloses a double - adjustable pushing beam for a scraper conveyor. The pushing beam can adapt to the coal mining face by changing its installation position. During the production process, due to the change in the length of the working face, in order to change the length of the scraper conveyor, after adding or removing the adjustment groove, the utility model can realize the reasonable adjustment of the connection position between the scraper conveyor and the hydraulic support. The utility model not only solves the problem of setting the pushing point of the hydraulic support after adding the adjustment groove when the length of the fully - mechanized coal mining face changes, but also reduces the equipment production and procurement costs, with obvious economic benefits.
