Description

Method for guiding multi-point support reciprocating impactor and guiding multi-point supporting reciprocating impactor device implementing same

Technical field

The invention relates to the field of machinery, and is suitable for the field of reciprocating driving, and is particularly suitable for a method for guiding a multi-point supporting reciprocating impactor in the field of mining or crushing or loading, and a guiding multi-point supporting reciprocating impactor device implementing the method.

Background technique

The shearer, the roadheader and the excavator are collectively referred to as the mining machine. The invention with the patent number 96100994.2 proposes an impact type coal mining machine. The impact coal falling mechanism of the mining machine is a reciprocating impact mining, due to the reciprocating impact of the impact device. The impactor is heavy and bulky, and its guiding device uses sliding friction. Therefore, it only has been drilled for more than ten meters at the site. Due to the serious wear of the guiding device, it cannot continue to work. Other impact shearers use rolling friction. The use effect is improved, but since the reciprocating impactor is large in height and large in volume, and the guiding rolling body is disposed inside the supporting portion, the guiding member of the reciprocating impactor is disposed on the inner side of the supporting portion and the guiding rolling body, and the guiding member reciprocates The support has a narrow support width and a small number of support points, and the upper guide rolling element has no supporting effect on the rolling friction of the reciprocating impactor. The upper part of the guiding member is provided with a rolling body, and the connecting width and height of the guiding member and the reciprocating impactor are connected. Reduced, the weight of the reciprocating impactor is applied to the lower guiding rolling body, the large reciprocating impactor When hitting the coal wall or rock wall or cement concrete, etc., it is subjected to a large external force to discriminate the impact. The impactor applies the discriminating force to the guide member with a narrower righting width and a small righting point for the reciprocating impactor. For the damage of the rolling elements and the power system, the guiding rolling elements are arranged at the upper and lower ends of the impact guiding members. Because the upper and lower rolling bodies need to occupy a large space, the size of the impact guiding members supporting the righting impact head is relatively reduced, resulting in support and righting. The strength of the impact head is insufficient. The upper and lower guiding rolling elements are arranged on the outer side of the impact guiding member to increase the height and/or the width of the impact guiding mechanism. When the multi-layer impact head is provided, the higher guiding mechanism must make the upper and lower impact heads be compared. Larger, higher impact head must increase the impact resistance, especially because the impact head such as the shearer must be larger than the height and width of the power box, only after the impact head impacts more than the height and width of the power box and the impact head When the total height of the mining is greater than the total height of the fuselage, the power box and the fuselage can pass through to achieve continuous coal mining, for example, reciprocating impact In order to match the flexible scraper conveyor for reloading, the coal machine must have a certain amount of mining undercover. In order to facilitate the smooth advancement of the hydraulic support, there must be sufficient cutting amount. Therefore, the impact head must have a certain height, ie The impact head must be made larger and heavier, but the larger and heavier impact head impacts the material when the material contact area is large, so that the reaction force is concentrated and strong. When the material is impacted, the impact of the upper and lower impact teeth is large, and the force is strong. Unevenness is easy to produce lateral force' Lateral force and impact reaction force are transmitted to the drive mechanism and the fuselage, which is easy to damage the drive mechanism. The impact reaction force easily resonates with the fuselage to deform the fuselage. In severe cases, it will cause impact mining. The problem of regional collapse and other problems causes serious damage to the equipment that cannot be continuously operated. In order to solve the above problems, the present invention proposes a method for guiding a multi-point support reciprocating impactor.
