A reciprocating impact excavator with a rolling guide and anti-rotation assembly block that implements the rolling-guiding anti-rotation assembly block-guiding anti-rotation method

Abstract

The invention belongs to the field of machinery, and in particular relates to a reciprocating impact excavator equipped with a rolling guide and anti-rotation assembly block, which implements a method of installing a rolling guide and anti-rotation assembly block for guiding and anti-rotation. device, rolling guide anti-rotation component block, integrated block connector, guide anti-rotation box seal and reciprocating punching teeth. The reciprocating punching teeth are set at the front end of the interlocking guide seal gear seat, and a connecting rod drives a single gear seat. Single pinion seat reciprocating impactor, a connecting rod drives multi-pinion seat to form a multi-pinion seat reciprocating impactor, install rolling guide anti-rotation assembly block to increase guide cohesion force, increase guide righting force, install rolling guide anti-rotation assembly The block makes a plurality of supporting lugs supporting multiple rolling guide stops into an integrated plate, and the integrated plate makes the space for supporting multiple rolling guide stoppers intensified and materialized, and improves the support for multiple rolling guide stoppers. positioning accuracy.

[0002] Due to the impact of the reciprocating impact roadheader on the coal wall, rock wall, concrete, etc. during the excavation process, the hard rock wall, concrete, etc. make the reciprocating impact part bear super strong reaction force, and the super strong reaction force has a certain impact on the reciprocating impact part. The super destructive force has resulted in frequent damage to the box seals, reciprocating impact power components, and reciprocating impact guide components of the reciprocating impact roadheader, and a large amount of maintenance. The main reasons are: 1. The support of the components is to set ear plates supporting each roller on the inner wall of the box composed of four-sided box plates. Except one side of each ear plate is connected with the box body, the rest of the parts are suspended in the air, and the ear plates are not connected to each other. Enhancing the strength of each supporting ear plate means making the ear plate bigger, which increases the volume of the box body, resulting in waste of space and material waste. Because of the poor support strength of the ear plate, the axial positioning of the roller is poor; 2. Inside the box The contact surface between the guide section and the rolling body produces partial sliding friction; 3. There are many processes in the processing of the bearing hole seats supporting more than two rolling bodies on the box, and it cannot be completed at one time by clamping one tool at a time, resulting in more than two The concentricity of the bearing seat is poor; 4. The axial positioning difference of more than two bearings makes it difficult for the axis of the two bearings to be perpendicular to the reciprocating impact guide rod after installation, so that the surface of the rolling body supported by the bearing and the reciprocating impact guide rod The surface fit is poor, resulting in a part of the surface with too large a gap, and a part of the surface is over-extruded. When the high-frequency impact of the reciprocating impact guide rod, the high temperature of the over-extruded part will cause deformation and damage to the parts, and the linearity of the reciprocating impact will be poor. The box seal section of the impact guide rod wears the box seal part, causing the seal to be damaged quickly, causing the power part in the box to generate high temperature due to the loss of lubricating and cooling fluid, and the severe high temperature deforms and damages the power part; 5. Support reciprocating The design and production of the rolling element surface of the impact guide rod and the surface of the reciprocating impact guide rod are not designed. When the reciprocating impact guide rod is subjected to a strong lateral force impact, even if the impact guide rod swings to a certain extent, the joint surface will still not The structure that produces sliding friction; 6. The design and manufacture of the surface of the rolling body supporting the reciprocating impact guide rod and the surface of the reciprocating impact guide rod has not been designed and manufactured so that when the reciprocating impact guide rod is subjected to a strong lateral force impact, the reciprocating impact guide rod The multiple sides of the rod are in a flat state and the surface of multiple rolling elements is respectively attached to the structure of rolling friction rolling guide, and the original design does not use strong control to avoid the swing of the reciprocating impact guide rod due to lateral force impact; 7. Reciprocating impact guide The rod is not equipped with a structure to widen and / or heighten the righting impact guide rod, so that the righting strength of the reciprocating impact guide rod is poor, so that the strong reaction force generated by the reciprocating impact directly acts on the reciprocating impact power components, resulting in damage to
