Abstract
The invention provides a crushing roller side protection mechanism, which is characterized in that: comprises wear-resistant pieces arranged on two side surfaces of a crushing roller of the crusher; each side surface of the crushing roller is provided with a plurality of mounting positions; the wear-resistant part is detachably arranged in the mounting position. The detachable and replaceable wear-resistant parts are arranged on the two side surfaces of the roller, so that the roller side plates are effectively protected, the rapid replacement of the wear-resistant parts is possible, and the thickness of the wear-resistant parts can be accurately controlled within a proper range.
Description
Technical Field
The invention relates to the field of maintenance of pavement crushers, in particular to a detachable wear-resisting plate on the side of a crushing roller and an arrangement method thereof.
Background
A crushing roller of the crusher forms a groove on a road surface in the process of crushing forwards and downwards. As shown in fig. 1, the side walls of the grooves rub against the sides of the roller, easily resulting in excessive wear of the roller sides.
The side wear-resisting plates of the crushing roller of the existing crusher are all of welded structures. If the wear plate is worn excessively, the wear plate can only be welded again on site, which is inconvenient. And the thickness of the wear plate cannot be accurately controlled.
Disclosure of Invention
As shown in fig. 1, the side surfaces of the rollers also need to have anti-wear measures. Therefore, the invention aims to overcome the defects and realize the protection of the side surfaces of the roller by installing a set of wear-resisting mechanisms on the two side surfaces of the roller.
The invention provides a crushing roller side protection mechanism, which is characterized in that: comprises wear-resistant pieces arranged on two side surfaces of a crushing roller of the crusher;
each side surface of the crushing roller is provided with a plurality of mounting positions;
the wear-resistant part is detachably arranged in the mounting position.
Further, the invention provides a crushing roller side protection mechanism, which is characterized in that: the number of the single side of the wear-resistant part is 2-16.
Further, the invention provides a crushing roller side protection mechanism, which is characterized in that: the distance between the wear-resistant pieces and the axis of the roller is distributed in a stepped manner from near to far.
Further, the invention provides a crushing roller side protection mechanism, which is characterized in that: the wear-resistant piece is annularly arranged on the side surface of the crushing roller to form a wear-resistant ring surface.
Further, the invention provides a crushing roller side protection mechanism, which is characterized in that: the wear-resistant part adopts a high-strength bolt with strength above 8.8 grade.
Further, the invention provides a crushing roller side protection mechanism, which is characterized in that: the structure that wearing parts and broken roller side contact is the helicitic texture, installs in the installation position of broken roller side through the spiro union mode.
Further, the invention provides a crushing roller side protection mechanism, which is characterized in that: the shape of the external visual surface of the wear-resistant part is rectangular, cylindrical, arc or hexagonal.
Further, the invention provides a crushing roller side protection mechanism, which is characterized in that: the mounting positions are sunken or raised on the side surfaces of the crushing rollers.
Effects and effects of the invention
The detachable and replaceable wear-resistant parts are arranged on the two side surfaces of the roller, so that the roller side plates are effectively protected, the rapid replacement of the wear-resistant parts is possible, and the thickness of the wear-resistant parts can be accurately controlled within a proper range.
In addition, the working process of the roller related to the invention is to dig and crush a groove downwards on the ground to form a vertical surface on the side surface, the vertical surface is formed by a certain crushing cutter head, and the existing high-strength wear-resistant part can be used as the crushing cutter head.
Drawings
Fig. 1 is a schematic diagram showing the operation of a crushing roller of the crusher to form a groove in a road surface during forward and downward crushing;
fig. 2 is a schematic view showing the installation of the crushing roller side protection mechanism according to the present embodiment.
Detailed Description
As shown in fig. 2, the present embodiment provides a side protection mechanism for a crushing roller, which is 4 wear-resistant pieces mounted on two sides of the crushing roller of a crusher, and the number of the wear-resistant pieces can be 2-16 according to the size of the roller and the requirement of practical use, and the wear-resistant pieces are generally arranged in pairs and uniformly arranged on the outer surface of the roller.
In order to realize the installation of the wear-resistant part, each side surface of the crushing roller is provided with a plurality of installation seats in a slotting mode, and internal threads are arranged in the installation seats;
the lower end part of the wear-resistant part is of an external thread structure, the external thread structure is matched with the internal thread structure, and the internal thread and the external thread can be butted in a screwing mode, so that the wear-resistant part is easily installed on the roller or detached from the roller.
The wear-resistant part is a high-strength bolt with strength of more than 8.8 grades, and the external view surface of the wear-resistant part can be any geometric figure with a rectangular shape, a cylindrical shape, an arc shape or a hexagonal shape.
As a variant, the wear parts may also be stepped from the near to the far from the roller axis.
